Detailed implementation manners

[0049] In order to better understand the above technical solutions, the technical solutions of the embodiments of the present application will be described in detail below through the accompanying drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0050] Such as Figures 1 to 5As shown in the figure, a durability test bench for a touch switch 210 is proposed according to an embodiment of the present application, including: a frame body 110; a support plate 120, which is inclined and arranged on the frame body 110; a fixing member 130, which is slidably connected to the support plate 120, and the fixing member 130 is used to fix the touch switch 210; a driving assembly 140, which is slidably connected to the frame body 110, wherein the sliding direction of the driving assembly 140 intersects with the sliding direction of the fixing member 130; a bionic structure 150, which is connected to the driving assembly 140, and the driving assembly 140 is used to drive the bionic structure 150 to move towards or away from the touch switch 210.

[0051] The durability test bench for the touch switch 210 provided by the embodiment of the present application is provided with a frame body 110, a support plate 120, a fixing member 130, a driving assembly 140 and a bionic structure 150. Among them, the support plate 120 is inclined and arranged on the frame body 110, and the inclination angle can simulate the inclination angle of the vehicle instrument panel, so as to simulate the scenario of a user clicking on the touch switch 210 at the instrument panel. The fixing member 130 is slidably connected to the support plate 120, and the touch switch 210 is fixed by the fixing member 130, so that the touch switch 210 can slide relative to the support plate 120, thereby simulating various positions of the touch switch 210 on the instrument panel and improving applicability. The driving assembly 140 is slidably connected to the frame body 110, and the bionic structure 150 is connected to the driving assembly 140. The driving assembly 140 is used to drive the bionic structure 150 to move towards or away from the touch switch 210 to simulate the scenario of a user clicking on the touch switch 210. And the sliding direction of the driving assembly 140 intersects with the sliding direction of the fixing member 130 to be applicable to various clicking scenarios, and the positioning of the bionic structure 150 is precise, so that the durability data of the touch switch 210 obtained by testing is more accurate.

[0052] It can be understood that the durability test bench for the touch switch 210 provided by the embodiment of the present application can test touch switches 210 of various sizes and types to meet the layout designs of various touch switches 210 in vehicles. By adjusting the sliding position of the fixing member 130 relative to the support plate 120 and adjusting the sliding position of the driving assembly 140 relative to the frame body 110, the distance between the finger and the touch switch 210 and the position of the finger on the touch switch 210 when the user is normally using the touch switch 210 can be simulated, thereby improving the simulation degree of the human body clicking on the touch switch 210 and improving the accuracy of the durability test of the touch switch 210. Exemplarily, the support plate 120 is inclined at 45° to 70° relative to the bottom of the frame body 110 to simulate the inclination angle of the vehicle instrument panel, so as to better simulate the scenario of a user clicking on the touch switch 210 at the instrument panel.

[0053] In some examples, such as Figures 1 to 5As shown, the above-mentioned driving assembly 140 includes: a support rod 141, a first sliding groove 111 is provided on the above-mentioned frame body 110, and the above-mentioned support rod 141 is slidably connected to the above-mentioned first sliding groove 111; a support frame 142, which is arranged on the above-mentioned support rod 141; a driving motor 143, which is arranged on the above-mentioned support frame 142; a stop yoke mechanism 144, which is respectively connected to the above-mentioned driving motor 143 and the above-mentioned bionic structure 150, and the stop yoke mechanism 144 is used to drive the above-mentioned bionic structure 150 to move closer to or away from the above-mentioned touch switch 210 under the drive of the above-mentioned driving motor 143.

[0054] It can be understood that the driving assembly 140 is provided with a support rod 141, a support frame 142, a driving motor 143 and a stop yoke mechanism 144. Among them, first sliding grooves 111 are provided at corresponding positions on both side walls of the frame body 110, and both ends of the support rod 141 are slidably connected to the two first sliding grooves 111 respectively. The support frame 142 is arranged on the support rod 141 and is used to support the driving motor 143. The stop yoke mechanism 144 is connected to the output shaft of the driving motor 143, and the bionic structure 150 is connected to the stop yoke mechanism 144. The stop yoke mechanism 144 can convert the rotational force provided by the driving motor 143 into the power for the bionic structure 150 to move closer to or away from the test touch switch 210. With such a setting, it can simulate the process of a human body clicking on the touch switch 210 and the movement of a finger. Exemplarily, the stop yoke mechanism 144 can be a Scotch yoke mechanism. Utilizing the characteristics of the Scotch yoke mechanism, during the process of the bionic structure 150 approaching the touch switch 210, the closer it is to the touch switch 210, the slower the speed will be, which better simulates the scenario of deceleration when the user is about to touch the touch switch 210 and improves the simulation accuracy.

[0055] It can be understood that threads can be provided at both ends of the support rod 141. After adjusting the support rod 141 to a specified position, a nut can be screwed into the threads at both ends of the support rod 141 and abutted against the frame body 110 to fix the support rod 141 and improve stability. After adjusting the position of the support frame 142 at the support rod 141, the support frame 142 can be fixed by bolts, and the driving motor 143 can be fixed to the support frame 142 by bolts to further improve stability.

[0056] In some examples, as Figure 1 and Figure 2 shown, the above-mentioned stop yoke mechanism 144 includes: a transmission wheel 1441, which is connected to the output shaft of the above-mentioned driving motor 143, and a slider 1443 is arranged on the above-mentioned transmission wheel 1441; a frame body 1442, which is connected to the above-mentioned transmission wheel 1441, the above-mentioned slider 1443 is located inside the above-mentioned frame body 1442 and is used to slide inside the above-mentioned frame body 1442, and the above-mentioned bionic structure 150 is connected to the outer wall of the above-mentioned frame body 1442 on the side close to the above-mentioned support plate 120.

[0057] It can be understood that the anti-rotation yoke mechanism 144 is provided with a transmission wheel 1441 and a housing 1442. Among them, the output shaft of the driving motor 143 can drive the transmission wheel 1441 to rotate. A slider 1443 can be arranged at the end face of the transmission wheel 1441, and the slider 1443 can slide along the diameter direction of the transmission wheel 1441 to adjust the position of the slider 1443. The slider 1443 is located inside the housing 1442 and can slide inside the housing 1442 towards both ends of the housing 1442. The bionic structure 150 is connected to the outer wall of the housing 1442 on the side close to the support plate 120. With such a setting, when the driving motor 143 is started, the transmission wheel 1441 drives the slider 1443 to rotate. While the slider 1443 slides inside the housing 1442, it drives the housing 1442 to move linearly towards or away from the touch switch 210. Furthermore, the housing 1442 drives the bionic structure 150 to move linearly towards or away from the touch switch 210. With such a setting, it can simulate the process of a human finger moving when clicking the touch switch 210.

[0058] It can be understood that the two side walls of the housing 1442 limit the stroke of the slider 1443, thereby limiting the distance that the bionic structure 150 moves towards or away from the touch switch 210. And since the slider 1443 is subject to a greater resistance from the housing 1442 when it approaches the side wall of the housing 1442, the sliding speed is reduced. As a result, when the distance between the bionic structure 150 and the touch switch 210 is at the minimum and maximum, the moving speed is the slowest. This better simulates the scenario of deceleration when the user is about to touch the touch switch 210 and improves the simulation accuracy.

[0059] In some examples, as Figures 1 to 4 shown, the above-mentioned bionic structure 150 includes: a hydraulic rod 151, connected to the outer wall of the above-mentioned housing 1442 on the side close to the above-mentioned support plate 120; a simulated capacitive finger 152, connected to one end of the above-mentioned hydraulic rod 151 close to the above-mentioned support plate 120, for clicking the above-mentioned touch switch 210; wherein, an included angle is provided between the above-mentioned hydraulic rod 151 and the above-mentioned simulated capacitive finger 152.

[0060] It can be understood that the bionic structure 150 is provided with a hydraulic rod 151 and a simulated capacitive finger 152. Among them, the hydraulic rod 151 is connected to the outer wall of the frame 1442 close to the support plate 120. By adjusting the telescopic length of the hydraulic rod 151, the initial distance between the simulated capacitive finger 152 and the touch switch 210 can be adjusted to mimic the distance of a human finger touching the touch switch 210, so as to be able to simulate the influence of various touch distances on the durability of the touch switch 210, improve the applicability, and further ensure the reliability and accuracy of the test. Moreover, the distance adjustment range is small, and only the telescopic movement of the hydraulic rod 151 is required, which improves the debugging efficiency, avoids adjusting too many parts, affects the test accuracy and takes a long time. And the hydraulic rod 151 moves smoothly, improving the stability. The simulated capacitive finger 152 can trigger the touch switch 210 to simulate the scenario of a human finger triggering the touch switch 210.

[0061] It can be understood that an included angle is provided between the hydraulic rod 151 and the simulated capacitive finger 152. To avoid the simulated capacitive finger 152 clicking the touch switch 210 vertically, but clicking the touch switch 210 in a direction close to the horizontal direction. Such a setting takes into account the clicking angle when the user clicks the touch switch 210 at the inclined instrument panel, thereby improving the simulation realism and the simulation accuracy.

[0062] In some examples, such as Figures 1 to 4 shown, the above-mentioned touch switch 210 durability test bench further includes: a lifting lug 160, which is arranged on the above-mentioned support frame 142, and the above-mentioned hydraulic rod 151 passes through the above-mentioned lifting lug 160.

[0063] It can be understood that the touch switch 210 durability test bench is also provided with a lifting lug 160. The lifting lug 160 is connected to one side of the support frame 142 close to the hydraulic rod 151, so that the hydraulic rod 151 passes through the lifting lug 160. By the lifting lug 160, the degree of freedom of the hydraulic rod 151 is limited, avoiding the hydraulic rod 151 from shaking during the subsequent process of the simulated capacitive finger 152 clicking the touch switch 210 multiple times, improving the stability, and ensuring the accuracy of the durability test data of the touch switch 210.

[0064] In some examples, such as Figures 1 to 3 shown, one end of the above-mentioned simulated capacitive finger 152 close to the above-mentioned support plate 120 is made of silica gel material.

[0065] It can be understood that in order to ensure the authenticity of the imitation, the touch between the simulated capacitive finger 152 and the touch switch 210 should simulate the feel of a human finger touching the touch switch 210. One end of the simulated capacitive finger 152 used to click the touch switch 210 is made of silica gel material to ensure the reliability and accuracy of the test.

[0066] In some examples, such as Figures 1 to 3As shown, the above-mentioned bionic structure 150 further includes: a spraying member 153, connected to the above-mentioned frame 110, for spraying water on one end of the above-mentioned simulated capacitive finger 152 close to the above-mentioned support plate 120; a heating member, arranged at one end of the above-mentioned simulated capacitive finger 152 close to the above-mentioned support plate 120.

[0067] It can be understood that the bionic structure 150 is also provided with a spraying member 153 and a heating member. Among them, the spraying member 153 is connected to the frame 110, and water mist is sprayed on one end of the simulated capacitive finger 152 for clicking the touch switch 210 through the spraying member 153 to simulate the scenario of human fingers sweating. The amount and density of the sprayed water mist can be adjusted according to the test content, improving the applicability and the test accuracy. And a heating member is arranged inside one end of the simulated capacitive finger 152 for clicking the touch switch 210 to simulate the temperature of human fingers, improving the simulation fidelity and further improving the test accuracy.

[0068] In some examples, the above-mentioned bionic structure 150 further includes: a displacement sensor, arranged inside the above-mentioned simulated capacitive finger 152; a counter, arranged inside the above-mentioned simulated capacitive finger 152; a pressure sensor, arranged inside the above-mentioned simulated capacitive finger 152; among them, the above-mentioned displacement sensor, the above-mentioned counter and the above-mentioned pressure sensor are all located at one end of the above-mentioned simulated capacitive finger 152 close to the above-mentioned support plate 120.

[0069] It can be understood that the bionic structure 150 is also provided with a displacement sensor, a counter and a pressure sensor. Specifically, the displacement sensor, the counter and the pressure sensor are all located at one end of the simulated capacitive finger 152 for clicking the touch switch 210. The moving distance of the simulated capacitive finger 152 is detected in real time by the displacement sensor. The current click times of the simulated capacitive finger 152 are recorded in real time by the counter. The contact pressure between the simulated capacitive finger 152 and the touch switch 210 is detected in real time by the pressure sensor. And the detected data can be transmitted to the database for summarizing and analyzing the data, which is convenient for subsequent improvement of the touch switch 210 to improve the durability of the touch switch 210, and further improve the durability of the whole vehicle, improve the performance and improve the user experience.

[0070] In some examples, as Figures 1 to 4 shown, the above-mentioned support plate 120 is provided with a second sliding groove 121, and the above-mentioned fixing member 130 slides along the above-mentioned second sliding groove 121.

[0071] It can be understood that the support plate 120 may be provided with a plurality of second sliding grooves 121, and the adjacent second sliding grooves 121 are arranged at intervals. The fixing member 130 can slide along the second sliding groove 121, and the corresponding second sliding groove 121 of the fixing member 130 can be selected according to the size of the touch switch 210. By adjusting the position of the touch switch 210 through the second sliding groove 121, it is convenient to conduct various position tests, improving applicability. Moreover, the second sliding groove 121 plays a guiding role in the movement of the fixing member 130, making the movement more stable and improving stability.

[0072] In some examples, such as Figure 1 shown, the above-mentioned touch switch 210 durability test bench further includes: a workbench 170, and the bottom end of the above-mentioned frame 110 is connected to the above-mentioned workbench 170.

[0073] It can be understood that the touch switch 210 durability test bench is also provided with a workbench 170. The bottom end of the frame 110 abuts against the workbench 170, providing support through the workbench 170 and changing the overall height. The frame 110 can be fixed to the workbench 170 by bolts to improve stability.
