Description

Technical Field

[0001] The utility model relates to the technical field of electric tailgate controllers, in particular to a testing device for an electric tailgate controller. Background Art

[0002] The electric tailgate of a car is the second component besides the door that has the function of opening and closing and storing objects. Its main function is to fix and carry objects that need to be carried. With the development of cars, the development of tailgates is becoming more and more intelligent, so more attention needs to be paid to safety.

[0003] In the prior art, the detection of the electric tailgate controller is too rigid and cannot simulate a more realistic actual usage scenario. It does not have a practical test function for the environment and objects that suddenly appear.

[0004] To overcome these shortcomings, prior art (Chinese patent application number: CN220932378U, filed on August 31, 2023) discloses an electric tailgate test device comprising a test chamber capable of controlling temperature and humidity. The device also features an internal obstacle simulation mechanism, an external obstacle simulation mechanism, and an anti-pinch simulation mechanism, all located within the test chamber. This device addresses the issue of existing electric tailgate test devices being unsuitable for testing electric tailgates with obstacle avoidance mechanisms.

[0005] Although the existing technology can solve the above problems, the test of the electric tailgate basically only has a fixed position prediction, and does not have the ability to test the electric tailgate controller for objects that suddenly appear, and the test of the electric tailgate is not comprehensive enough. Utility Model Content

[0006] The purpose of the present utility model is to provide an electric tailgate controller testing device to solve the problem raised in the above-mentioned background technology that the test of the electric tailgate basically only has the pre-judgment of a fixed position, is unable to test the electric tailgate controller for objects that suddenly appear, and the test of the electric tailgate is not comprehensive enough.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electric tailgate controller test device, comprising an anti-pinch rod installed on the surface of the base, and an anti-pinch plate installed at the front end of the anti-pinch rod, a hydraulic rod installed above the base, and support rods installed on the front and rear surfaces of the hydraulic rod, a tailgate simulation plate installed on the upper surface of the hydraulic rod, and the lower surface of the hydraulic rod is fixedly connected to the base, a first slide groove is installed on the left side of the anti-pinch plate, and a traction trigger mechanism for sliding the first simulation block back and forth is installed above the first slide groove, the traction contact mechanism includes a first simulation block, and the first simulation block is installed A first inner groove is provided above the first slide groove, the first simulation block slides along the inner track of the first inner groove, a spring is installed at the front end of the first inner groove, and the end of the motion track of the first simulation block contacts the spring, a positioning support plate is installed above the first slide groove, and the positioning support plate is installed on the motion track of the first simulation block, and the front end protrusion of the first simulation block passes through the positioning support plate, a wire group is installed above the first simulation block, and the other end of the wire group is installed on the surface of the tailgate simulation plate, a transmission roller is installed on the surface of the support rod, and the wire group passes through the inside of the transmission roller;

[0008] A second slide rail is installed above the support rod, and an inclined push-pull mechanism for sliding the second simulation block is installed above the second slide rail.

[0009] Furthermore, the inclined push-pull mechanism includes a second simulation block installed above the second slide rail, and the upper surface of the second slide rail is provided with a second inner groove, and the second simulation block slides along the inner track of the second inner groove.

[0010] Furthermore, a third inner groove is formed on the surface of the second simulation block, and a sliding resistance rod is installed inside the third inner groove. A sliding support frame is installed on the lower surface of the second slide rail, and the sliding resistance rod passes through the inside of the sliding support frame.

[0011] Furthermore, the inner surface of the first inner groove contacts the lower surface of the first simulation block to form a sliding structure, and the front end of the first simulation block contacts the interior of the positioning support plate to form a sliding structure.

[0012] Furthermore, the surface of the wire group contacts the surface of the transmission roller to form a sliding structure, and the tailgate simulation plate contacts the surface of the first simulation block through the end of the wire group to form a traction structure.

[0013] Furthermore, the anti-pinch rod and the anti-pinch plate are an integrated structure, and the anti-pinch rod and the anti-pinch plate as well as the wire group and the transmission roller are all installed symmetrically about the center point of the base.

[0014] Furthermore, the outer surface of the sliding resistance rod contacts the interior of the third inner groove to form a sliding structure, and the outer surface of the sliding resistance rod contacts the interior of the sliding support frame to form a sliding structure, and the interior of the sliding support frame is also inclined according to the corresponding inclination angle of the sliding resistance rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the electric tailgate controller test device utilizes the downward contraction of the hydraulic rod to move the wire groups fixed on the left and right sides of the tailgate simulation plate downward. Since the middle part of the wire group passes through the transmission roller and the end is fixed to the first simulation block, the first simulation block is continuously pulled closer to the bottom of the tailgate simulation plate until the controller senses the presence of an object and stops moving. This design increases randomness and tests whether the controller has corresponding preventive measures against objects that suddenly appear during the landing process.

[0016] Furthermore, the upward extension of the hydraulic rod causes the tailgate simulation plate to push up the sliding resistance rod, causing it to slide along the inside of the third inner groove. Since the sliding resistance rod is placed on an inclined surface, the interior of the sliding support frame is also designed with a corresponding inclined surface. Therefore, the sliding resistance rod slides upward to push the second simulation block to slide along the second inner groove. This design tests the controller's defensive response to the presence of a moving object above the tailgate.

[0017] Furthermore, a spring is installed inside the first inner groove. After the first simulation block completes the triggering work, the first simulation block is bounced away from the positioning support plate through the elastic action of the spring. This design facilitates the next test of the controller and better detects the sudden reaction function of the controller. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figure 1-6 The utility model provides the following technical solution: an electric tailgate controller testing device, including a base 1, a first slide groove 2 and a second slide rail 19.

[0027] An anti-pinch rod 7 is installed on the surface of the base 1, and an anti-pinch plate 8 is installed at the front end of the anti-pinch rod 7. A hydraulic rod 17 is installed above the base 1, and support rods 18 are installed on the front and rear surfaces of the hydraulic rod 17. A tailgate simulation plate 9 is installed on the upper surface of the hydraulic rod 17, and the lower surface of the hydraulic rod 17 is fixedly connected to the base 1. A first slide 2 is installed on the left side of the anti-pinch plate 8, and a traction trigger mechanism for sliding the first simulation block 4 back and forth is installed above the first slide 2. The traction contact mechanism includes a first simulation block 4, which is installed above the first slide 2, and a first inner Groove 3, the first simulation block 4 slides along the inner track of the first inner groove 3, and a spring 5 is installed at the front end of the first inner groove 3, and the end of the movement track of the first simulation block 4 contacts the spring 5, a positioning support plate 6 is installed above the first slide groove 2, and the positioning support plate 6 is installed on the movement track of the first simulation block 4, and the front end protrusion of the first simulation block 4 passes through the positioning support plate 6, a wire group 10 is installed above the first simulation block 4, and the other end of the wire group 10 is installed on the surface of the tailgate simulation plate 9, a transmission roller 11 is installed on the surface of the support rod 18, and the wire group 10 passes through the inside of the transmission roller 11;

[0028] A second slide rail 19 is installed above the support rod 18 , and an inclined push-pull mechanism for sliding the second simulation block 13 is installed above the second slide rail 19 .

[0029] like Figure 1 、 Figure 2 、 Figure 4The technical solution shown, in order to solve the problem that the tailgate cannot be tested for its reaction to suddenly appearing objects, discloses: the inner surface of the first inner groove 3 contacts the lower surface of the first simulation block 4 to form a sliding structure, and the front end of the first simulation block 4 contacts the inside of the positioning support plate 6 to form a sliding structure, the surface of the wire group 10 contacts the surface of the transmission roller 11 to form a sliding structure, and the tailgate simulation plate 9 contacts the surface of the first simulation block 4 through the end of the wire group 10 to form a traction structure, the anti-pinch rod 7 and the anti-pinch plate 8 are an integrated structure, and the anti-pinch rod 7 and the anti-pinch plate 8 as well as the wire group 10 and the transmission roller 11 are all installed symmetrically about the center point of the base 1.

[0030] The controller is connected to the hydraulic rod 17 so that the hydraulic rod 17 first contracts downward. While contracting, the tailgate simulation board 9 fixed above the hydraulic rod 17 moves downward synchronously, driving the wire groups 10 fixed on the left and right ends to contract downward. Since the wire group 10 passes through the transmission roller 11 fixed on the surface of the support rod 18, the middle part of the wire group 10 remains stationary. The first simulation block 4 connected to the other end slides forward along the first inner groove 3 as the tailgate simulation board 9 descends. After the first simulation block 4 hits the spring 5 and the front end passes through the inside of the positioning support plate 6, it reaches the test position. After the test is completed, the wire group 10 changes from being taut to being relaxed, and the spring 5 also resets it due to its elastic action to complete the test.

[0031] like Figure 3 、 Figure 5 、 Figure 6 The technical solution shown, in order to solve the problem of complex design of the reaction test device installed above the tailgate, discloses: the inclined push-pull mechanism includes a second simulation block 13 installed above the second slide rail 19, and the upper surface of the second slide rail 19 is provided with a second inner groove 12, the second simulation block 13 slides along the internal track of the second inner groove 12, the surface of the second simulation block 13 is provided with a third inner groove 16, and the interior of the third inner groove 16 is installed with a sliding resistance rod 15, the lower surface of the second slide rail 19 is installed with a sliding support frame 14, and the sliding resistance rod 15 passes through the interior of the sliding support frame 14, the outer surface of the sliding resistance rod 15 contacts the interior of the third inner groove 16 to form a sliding structure, and the outer surface of the sliding resistance rod 15 contacts the interior of the sliding support frame 14 to form a sliding structure, and the interior of the sliding support frame 14 is also inclined according to the inclination angle of the sliding resistance rod 15.

[0032] The controller controls the hydraulic rod 17 to move upward. After moving to a certain height, the tailgate simulation plate 9 will contact the end of the sliding resistance rod 15 and continuously push up the sliding resistance rod 15 along the sliding support frame 14 during the movement. After the sliding resistance rod 15 passes through the sliding support frame 14, it also slides inside the third inner groove 16. The interior of the third inner groove 16 has the same inclination angle as the sliding resistance rod 15 and maintains an inclined state. Since the second simulation block 13 slides inside the second inner groove 12, the sliding resistance rod 15 moves upward while continuously sliding the second simulation block 13 inward along the second inner groove 12 to achieve the moving effect. In this way, whether the controller has the function of corresponding measures when there is a moving object above the tailgate is detected, and if the hydraulic rod 17 fails during the descent process, the anti-pinch rod 7 and anti-pinch plate 8 installed on both sides of the base 1 can effectively block the tailgate simulation plate 9 to prevent damage to the entire machine.
