Electric trunk release

Types of Electric Trunk Release

An electric trunk release is a popular feature on modern vehicles that enables drivers and passengers to open the trunk with a button press or switch activation. This mechanism is particularly useful when hands are full or in adverse weather conditions. The electric trunk release comprises an electric motor, a solenoid latch, and a switch or button. It interacts with the vehicle's central locking system for added security, ensuring the trunk can only be opened when the vehicle is stationary.

The types of electric trunk releases include:

• Touch Sensor Trunk Release:

  Touch sensor trunk releases have become a standard feature in contemporary vehicles, enhancing convenience. These sensors are typically embedded in the trunk lid or near the license plate area. When the driver approaches the vehicle with the key fob in their possession, the sensor detects the key's presence. This triggers the vehicle's body control module to unlock the trunk lid, allowing access without fumbling for the key fob button in one's pocket or purse. Moreover, during trunk opening, the touch sensor can also initiate trunk lid movement, reducing the force required to open the trunk. This feature is especially beneficial for individuals with physical limitations or when the car is loaded with groceries or sports equipment.

• Power Liftgate:

  A power liftgate is a feature commonly found in SUVs and minivans, allowing for automatic opening and closing of the vehicle's rear trunk. This feature simplifies loading and unloading cargo, especially for individuals with mobility challenges or when transporting large items. Activating the power liftgate can be done through buttons located on the key fob, the liftgate itself, or on the dashboard inside the vehicle. Additionally, the power liftgate can be programmed to open to a predetermined height, accommodating for situations where parking space is limited. Moreover, some power liftgates incorporate hands-free technology. Sensors near the rear bumper detect a foot movement, prompting the liftgate to open. This hands-free activation proves invaluable when one’s hands are full, eliminating the need to search for or press the key fob button.

• Trunk Release Button:

  The trunk release button is a simple yet effective way to enhance trunk access in various vehicles. Typically located on the key fob, within the driver's side door panel, or on the center console, this button connects to the vehicle's central locking system. Its primary function is to disengage the trunk lid from the vehicle body, allowing for easy trunk access. Some trunk release buttons also incorporate a delay mechanism, requiring a prolonged button press to prevent accidental trunk opening. This delay provides an extra layer of security and prevents unauthorized trunk access. Vehicles equipped with a trunk release button often feature a solenoid latch mechanism. This latch, activated by the electric motor, releases the trunk lid when the button is pressed. The hatchback lid usually has a spring mechanism to pull the lid down and a frame to hold the closed trunk.

Specification and maintenance of electric trunk release

• Load capacity

  The electric trunk release has a load capacity that varies depending on the car model. For example, a standard sedan trunk release handle can support up to 20 kg, while SUVs and hatchbacks can handle 30-40 kg. This load capacity includes the weight of the trunk lid and additional cargo.

• Trunk size

  The electric trunk release is designed for different car trunk sizes. A standard sedan trunk size is about 400-500 liters, while SUVs and hatchbacks have larger trunk sizes ranging from 500-700 liters. The electric trunk release mechanism is adapted to different trunk sizes to ensure smooth and safe opening and closing.

• Installation time

  The electric trunk release installation time may vary depending on the complexity of the mechanism and the car model. Typically, the installation of an electric trunk release takes from 2 to 5 hours, including the time for wiring, mounting, and testing. For some luxury cars, the installation of an electric trunk release can take up to 8 hours due to the need for integration with other electronic systems.

The electric trunk release is a convenient and useful feature for car owners, but it requires regular maintenance to ensure its smooth operation. Here are some tips to maintain the electric trunk release:

• 1. Keep it clean: Regularly clean the electric trunk release, including buttons, handles, and the trunk opening mechanism. Dirt, dust, or moisture can affect the operation of the electric system.
• 2. Check the wiring: Periodically inspect the wiring of the electric trunk release for any damage or wear. If there are any signs of damage, promptly replace the wiring to prevent problems with the trunk opening.
• 3. Lubricate moving parts: Periodically lubricate the moving parts of the electric trunk release, such as hinges and the trunk opening mechanism. Use a suitable lubricant, such as silicone grease or lithium grease, to ensure smooth operation and reduce friction.
• 4. Avoid overloading the trunk: Do not overload the trunk with excessive cargo. Exceeding the load capacity of the electric trunk release can lead to its malfunction and problems with opening and closing the trunk.
• 5. Follow the instructions: If the electric trunk release is not a standard feature of the car, carefully read the installation and operation instructions. Follow all recommendations of the manufacturer to ensure the correct operation of the electric system.

How to Choose Electric Trunk Release

Wholesale buyers should consider the following factors when sourcing electric trunk releases:

• Compatibility

  For a successful installation, ensure that the electric trunk release is compatible with the car's make, model, and year. It is recommended to use releases designed for specific vehicles. They are more likely to be compatible and require minimal modifications.

• Security

  The electric trunk release button should offer adequate security. A release that works with the car's central locking system will be secure. Additional security features like a trunk release delay or a hidden release button will prevent unauthorized access to the trunk.

• Quality

  At the end of the day, quality determines performance and durability. Look for reputable brands that are known for quality electric trunk releases. High-quality releases are made with durable materials and can withstand regular use. Quality releases also have fewer malfunctions.

• Ease of Installation

  Consider how easy it will be to install the electric trunk release. Releases that come with detailed instructions, wiring diagrams, and all necessary installation hardware will be easier to install. Also, look for releases that require simple installations, such as drilling holes. Complex installations are likely to be more difficult and take more time to install.

• Price

  Electric trunk releases are available at different price points. Set a budget but avoid cheap releases. They are likely to be of poor quality. Look for releases that offer value for money. The features and quality should match the price, and the price should be within the set budget.

• Warranty

  A warranty is a good indicator of the manufacturer's confidence in the quality of the electric trunk release. Look for releases that offer a reasonable warranty period. In case of defects, the warranty will protect the buyer.

• Customer Reviews

  Reading what other customers have to say about the electric trunk release can help the buyer make an informed decision. Customer reviews provide real-life information about the quality, performance, and ease of installation of the electric trunk release.
