Abstract
Description
Technical Field
[0001] This application relates to the field of automotive manufacturing technology, and more particularly to a dual-detection foot-operated trunk opening device. Background Technology
[0002] In the automotive manufacturing industry, cars are developing towards intelligence and functionality, with various functions becoming increasingly intelligent. For example, regarding the opening method of a car's trunk, traditional trunk opening is mostly achieved through buttons in the driver's cab. This type of opening method is known in the industry as a contact opening method. Currently, non-contact trunk opening methods are becoming more and more widespread. For example, a foot-operated non-contact trunk opening method involves installing a sensor at the trunk location. The sensor can detect a person's kicking motion and transmit the signal to the vehicle's controller, which then opens or closes the trunk. However, this opening method has certain drawbacks in practical applications. Because the sensor works by detecting the proximity of a person's foot, if other objects move near the sensor, it may be falsely triggered, causing the trunk to open accidentally. Utility Model Content
[0003] The purpose of this application is to provide a dual-detection foot-operated trunk opening device, which can open the trunk more accurately and prevent accidental opening of the trunk, thereby effectively solving the shortcomings of the prior art.
[0004] Therefore, this application provides a dual-detection foot-operated trunk opening device, comprising:
[0005] The first detector is installed in the trunk of the vehicle to detect foot movements;
[0006] The second detector is installed in the trunk of the vehicle to detect foot movements;
[0007] A drive assembly, installed on the vehicle body, to drive the trunk to switch between an open and closed state;
[0008] The controller is electrically connected to the first detector, the second detector, and the drive assembly, respectively.
[0009] The first and second detectors are located at different positions on the vehicle body. The controller is used to receive signals from the first and second detectors and drive the trunk to switch between open and closed states through the drive component.
[0010] In some possible implementations, the detection directions of the first detector and the second detector are located in the same vertical plane, which is parallel to the longitudinal length direction of the vehicle body.
[0011] In some possible implementations, the detection direction of the first detector is tilted toward the rear of the vehicle body, and / or the detection direction of the second detector is tilted toward the underside of the vehicle body.
[0012] In some possible implementations, the first detector is positioned horizontally and facing backward, while the second detector is positioned vertically and facing downward.
[0013] In some possible implementations, both the first and second detectors are plate antennas, and a capacitance is formed between the plate antennas and the ground.
[0014] In some possible implementations, the first detector and the second detector are respectively connected to the controller via coaxial cables.
[0015] In some possible implementations, both the first and second detectors are elongated plate-shaped antennas, with the length direction of both the first and second detectors arranged along the width direction of the vehicle body.
[0016] In some possible implementations, the first detector and the second detector are located at the middle of the width of the vehicle body in the width direction.
[0017] In some possible implementations, a light strip is also included, which has an extended length and extends in the width direction of the vehicle body. The extended length region of the light strip is the same as the extended length region of the first detector.
[0018] In some possible implementations, the first and second detectors extend for 60 centimeters.
[0019] According to the dual-detection foot-operated trunk opening device provided in this application embodiment, under the controller of the controller, the drive component can drive the trunk of the vehicle to switch from an open state to a closed state, or from a closed state to an open state. The first detector and the second detector are both located in the trunk of the vehicle. The first detector and the second detector can both be used to detect the kicking action of the person. After the first detector and the second detector detect the kicking action of the person's foot, they transmit the signal to the controller. Then the controller causes the trunk to open or close through the drive component. The first detector and the second detector form a dual detection, which greatly improves the fault tolerance rate, can effectively avoid false triggering, and can prevent the trunk from being opened accidentally.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] like Figures 1-2 As shown, this application provides a dual-detection foot-operated trunk opening device for vehicle trunk opening and closing operations. The trunk opening method has evolved from traditional contact-based methods to contactless methods. Contact-based methods include driver's seat buttons and trunk buttons. Currently, the most popular contactless trunk opening method is the foot-operated trunk opening method. In this method, a sensor is installed at the rear of the trunk. When a person kicks near the sensor, the sensor is triggered, and the vehicle control system switches the trunk from closed to open, or vice versa. However, this method has certain drawbacks in practical application. When other objects move near the sensor, it may trigger falsely, causing the trunk to open accidentally. This dual-detection foot-operated trunk opening device aims to eliminate the problem of false sensor activation and prevent accidental trunk opening.
[0024] The dual-detection foot-operated trunk opening device includes a first detector 201, a second detector 202, a drive assembly 300, and a controller 400. The first detector 201 and controller 400 are electrically connected, the second detector 202 and controller 400 are electrically connected, and the drive assembly 300 and controller 400 are electrically connected. The drive assembly 300 is located inside the vehicle body 90 and is used to switch the trunk from a closed state to an open state, or vice versa. The drive assembly 300 switches the trunk between open and closed states. The first detector 201 is located at the trunk of the vehicle body 90 and is used to detect foot movements. The second detector 202 is also located at the trunk and is used to detect foot movements. In this embodiment, the first detector 201 and the second detector 202 are located on the vehicle body 90... The controller 400 receives signals from the first detector 201 and the second detector 202. The controller 400 drives the trunk to switch between an open and closed state via the drive assembly 300. When both the first detector 201 and the second detector 202 detect foot movement (i.e., both are triggered by a kicking motion) and transmit signals to the controller 400, the controller 400 transmits a signal to the drive assembly 300 based on the received signal. If the trunk is closed, the controller 400 transmits a signal to the drive assembly 300 to open the trunk, causing it to switch from closed to open. Conversely, if the trunk is open, the controller 400 transmits a signal to close the trunk, causing it to switch from open to closed.
[0025] Therefore, under the combined action of the first detector 201 and the second detector 202, only when both the first detector 201 and the second detector 202 are triggered and simultaneously transmit signals to the controller 400 can the controller 400 drive the trunk to switch states through the drive component 300. Thus, the triggering condition for the trunk opening or closing action is a dual condition, which improves the fault tolerance rate. Compared with the single sensor method, this dual-detection foot-operated trunk opening device can effectively avoid false triggering and thus effectively prevent the vehicle's trunk from being opened accidentally.
[0026] Preferably, the detection directions of the first detector 201 and the second detector 202 are located in the same vertical plane, which is parallel to the longitudinal length direction of the vehicle body 90. In this embodiment, the detection direction of the first detector 201 is tilted towards the rear of the vehicle body 90, or the detection direction of the second detector 202 is tilted towards the lower part of the vehicle body 90. More preferably, the detection direction of the first detector 201 is tilted towards the rear of the vehicle body 90, and the detection direction of the second detector 202 is tilted towards the lower part of the vehicle body 90. In this way, the first detector 201 can detect the approach of a person kicking, while the second detector 202 can detect and capture the movement of the foot. This can form a continuous motion capture detection. More preferably, the detection direction of the first detector 201 is horizontal and towards the rear of the vehicle body 90, and the detection direction of the second detector 202 is vertical and downward. In this way, when a person opens the trunk, they are usually behind the vehicle body 90. When the person kicks, they first swing their leg towards the vehicle body 90. Then, the foot will extend to the bottom of the vehicle. Therefore, the first detector 201 is set on the rear side of the trunk of the vehicle body 90 and faces backward to detect. The second detector 202 is set on the bottom side of the trunk of the vehicle body 90 and faces downward to detect. The first detector 201 detects the person's leg approaching and transmits a signal to the controller 400. After the person kicks, the foot extends to the bottom of the vehicle body 90. The second detector 202 detects the approach of the person's foot and transmits a signal to the controller 400. After receiving the signals from the first detector 201 and the second detector 202, if the trunk is closed at this time, the controller 400 transmits a signal to the drive assembly 300 to open the trunk. The drive assembly 300 drives the trunk to switch from the closed state to the open state. If the trunk is open at this time, the controller 400 transmits a signal to the drive assembly 300 to close the trunk. The drive assembly 300 drives the trunk to switch from the open state to the closed state, thereby realizing the opening and closing control of the trunk.
[0027] In some examples, both the first detector 201 and the second detector 202 are plate antennas, forming a capacitance between the plate antennas and the ground. When a person's leg approaches the first detector 201, the capacitance value between the first detector 201 and the ground changes. When a person's foot extends into the bottom of the vehicle body 90 and approaches the second detector 202, the capacitance value between the second detector 202 and the ground changes. The controller 400 determines whether the first detector 201 and the second detector 202 are triggered based on the change in capacitance value.
[0028] A plate-shaped antenna can form a capacitance with the ground, and the detection of a person's legs and feet can be achieved by changing the capacitance value.
[0029] More preferably, both the first detector 201 and the second detector 202 are connected to the controller 400 via coaxial cables, making the signal transmission more stable and reliable.
[0030] More preferably, both the first detector 201 and the second detector 202 are elongated plate-shaped antennas. The lengths of both the first detector 201 and the second detector 202 are set along the width direction of the vehicle body 90, facilitating the detection of a person's legs and feet. In this embodiment, the first detector 201 and the second detector 202 are located in the middle of the width of the vehicle body 90, that is, the width direction of the vehicle body 90 is the left-right direction. The left and right sides of the width of the vehicle body 90 are symmetrical relative to these symmetrical planes. The first detector 201 and the second detector 202 are symmetrical along their lengths relative to these symmetrical planes. This allows for easy operation when a person performs a kicking motion in the middle of the vehicle body 90. In this embodiment, the first detector 201 is located above the second detector 202 on the vehicle body 90. The lengths of the first detector 201 and the second detector 202 are the same. The preferred extension length of the first detector 201 is 60 centimeters, facilitating detection within this area. More preferably, for detecting the feet and legs of pedestrians, a light strip 500 can be installed on the vehicle body 90. The light strip 500 has an extension length, and the extension direction of the light strip 500 is the width direction of the vehicle body 90. The extension area of the light strip 500 is the same as the extension area of the first detector 201. In this embodiment, the light strip 500, the first detector 201 and the second detector 202 have the same length, and the length direction of all three is the width direction of the vehicle body 90. Moreover, the position of the light strip 500 corresponds to the position of the first detector 201 and the second detector 202. The light strip 500 is symmetrically arranged about the left and right sides of the vehicle body 90 along the length direction. In this way, the position and detection range of the first detector 201 and the second detector 202 can be clearly observed through the light strip 500, and the position of the first detector 201 and the second detector 202 can be more accurately judged and determined. The triggering is more convenient, and it makes it easier for personnel to confirm which position on the vehicle body 90 to kick. The operation is more convenient and the convenience is greatly improved.
