[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0032] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted.

[0035] Currently, when conducting durability tests on one-touch door switches, a cylinder is generally installed on a test bench, and the outer door handle to be tested is installed on the test bench and directly opposite the cylinder. By controlling the operation of the cylinder, the cylinder piston rod is periodically extended and retracted, thereby frequently pressing the one-touch switch on the outer door handle.

[0036] With the increasing diversity and differentiation of vehicle designs, door handles on different cars have varying shapes and sizes, and the angles of their single-touch switches also vary. Existing testing devices typically only adjust the distance between the cylinder and the door handle, making it difficult to test single-touch switches on door handles of varying shapes and angles.

[0037] In response to the above situation, the present application provides a durability test device for a one-touch door switch, which is used to facilitate adjusting the angle and distance between the cylinder and the outside door handle when facing different outside door handles, so that the cylinder and the one-touch door switch are accurately aligned, thereby improving the applicability of the durability test device and facilitating accurate durability testing of different one-touch door switches.

[0038] The following combination Figure 1-Figure 3, a detailed introduction is given to the basic structure, working principle and technical effects achieved by a one-button door switch durability test device provided by this application.

[0039] Please refer to Figure 1 and Figure 2 This embodiment provides a vehicle door one-touch switch durability test device, which includes a test bench 100, a test actuator 200 and a test controller 300. The test bench 100 serves as a mounting and fixing base for the vehicle door outer handle 400, and the test bench 100 provides an installation position for the test actuator 200. The test bench 100 includes a bracket base 110, a column 120, a connector 130 and a mounting plate 140. The bracket base 110 can be detachably fixed to the test site ground or the test bench by connectors 130 such as screws, and the vehicle door outer handle 400 is fixed to the bracket base 110. Two columns 120 are vertically spaced apart on the base plate, and the two columns 120 are respectively located on both sides of the vehicle door outer handle 400. Connectors 130 are provided on both columns 120, and the connectors 130 can be moved along the length direction of the columns 120. The mounting plate 140 is connected and installed between the two connecting members 130 , and the test actuator 200 is installed on the mounting plate 140 .

[0040] In this embodiment, when conducting a durability test on the one-touch switch of the vehicle door, different vehicle door outer handles 400 are installed on the bracket base plate 110. According to the angle and position of the one-touch switch on the vehicle door outer handle 400, the positions of the connecting parts 130 on the two columns 120 are adjusted respectively, thereby adjusting the height and tilt angle of the mounting plate 140, so that the needle cylinder 210 in the test actuator 200 on the mounting plate 140 is accurately aligned with the one-touch switch, thereby improving the accuracy of the test.

[0041] In order to facilitate the fixing of the door handle 400 to the bracket base plate 110 during the durability test, please refer to Figure 1 On the bracket base plate 110, spacers 111 are installed on both sides of the exterior door handle 400. These spacers 111 are removably fixed to the bracket base plate 110 with screws, thereby clamping the exterior door handle 400 to the bracket base plate 110. Furthermore, to further adjust the height and angle of the exterior door handle 400, spacers of varying heights and sizes can be installed on the bracket base plate 110. The ends of the exterior door handle 400 are placed on different spacers and secured to the spacers via the spacers 111. This allows the height and angle of the one-touch switch on the exterior door handle 400 to be adjusted to facilitate alignment between the one-touch switch and the needle cylinder 210 in the test actuator 200.

[0042] Please refer to Figure 2 and Figure 3Connector 130 includes an L-shaped bracket 131, a first bolt 132, and a second bolt 133. L-shaped bracket 131 consists of two perpendicular plates and is commonly used to connect two perpendicular components. One side of L-shaped bracket 131 is connected to column 120 via first bolt 132, while the other side of L-shaped bracket 131 is connected to mounting plate 140 via second bolt 133.

[0043] When adjusting the height of the mounting plate 140, it is necessary to fix the L-shaped angle bracket 131 to different positions on the column 120. In order to facilitate the adjustment of the position of the L-shaped angle bracket 131 on the column 120, please refer to Figure 2 A slot 121 is provided along the length of the column 120, and a slider 134 is slidably disposed within the slot 121. A first bolt 132 passes through the openings of the L-shaped bracket 131 and the slot 121, then is threaded into the slider 134. Loosening the first bolt 132 and adjusting the position of the slider 134 along the slot 121 causes the L-shaped bracket 131 to move along the length of the column 120. After the L-shaped bracket 131 moves to the desired position, tightening the first bolt 132 secures the L-shaped bracket 131 to the column 120. This facilitates adjusting the position of the L-shaped bracket 131 and securing it.

[0044] Please refer to Figure 2 and Figure 3 Furthermore, the positions of the L-shaped brackets 131 on the two pillars 120 are adjusted so that they are vertically offset. The two L-shaped brackets 131 are then rotated and adjusted so that they are aligned on the same inclined plane, perpendicular to one side of the pillars 120. The mounting plate 140 is now tilted, and the tilt angle of the needle cylinder 210 in the test actuator 200 is then adjusted so that it aligns with the door switches at different angles, ensuring test accuracy.

[0045] Since the distance between the two L-shaped corner brackets 131 is different when the mounting plate 140 is tilted at different angles, the connection position between the mounting plate 140 and the L-shaped corner bracket 131 will change. In order to facilitate the adjustment of the connection position between the mounting plate 140 and the L-shaped corner bracket 131, please refer to Figure 2 A waist-shaped hole 141 is formed on the mounting plate 140 along its length. The second bolt 133 is passed through the waist-shaped hole 141. The second bolt 133 is moved along the length of the waist-shaped hole 141. After the second bolt 133 moves to a desired position, the second bolt 133 is tightened to secure the mounting plate 140 to the L-shaped bracket 131. This facilitates adjustment of the fixed position of the mounting plate 140 and the L-shaped bracket 131 when the tilt angle of the mounting plate 140 changes.

[0046] Please refer to Figure 2 and Figure 3 A strip hole 135 is formed on one side of the L-shaped angle bracket 131 perpendicular to the column 120, and a second bolt 133 is passed through the strip hole 135. By adjusting the position of the second bolt 133 within the strip hole 135, the position of the mounting plate 140 can be adjusted toward or away from the column 120, thereby further increasing the adjustment range of the mounting plate 140 and improving its applicability.

[0047] Please refer to Figure 1 and Figure 2 The test actuator 200 includes a needle cylinder 210. The outer diameter of the needle cylinder 210 is adapted to the waist-shaped hole 141 on the mounting plate 140. Threads are machined on the outer wall of the needle cylinder 210, and a nut 211 is threadedly mounted on the cylinder body of the needle cylinder 210. The nuts 211 are provided on both sides of the mounting plate 140. By tightening the two nuts 211 toward each other, the needle cylinder 210 is clamped and fixed to the mounting plate 140. At the same time, by adjusting the position of the nut 211 on the cylinder body of the needle cylinder 210, the position of the needle cylinder 210 can be adjusted, thereby driving the needle cylinder 210 toward or away from the door one-touch switch, making it easier to fine-tune the position of the needle cylinder 210.

[0048] Please refer to Figure 1 Furthermore, the test actuator 200 also includes a solenoid valve 220 and a pressure reducing valve 230. The outlet of the pressure reducing valve 230 is connected to the solenoid valve 220 via an air pipe, and the inlet of the pressure reducing valve 230 is connected to an external air source via an air pipe. The solenoid valve 220 is connected to the needle cylinder 210 via the air pipe. In this embodiment, the external air source is compressed air. The pressure reducing valve 230 is used to reduce the pressure of the compressed air output by the air compressor and output it so that the pressure of the compressed air input to the needle cylinder 210 is slightly greater than the pressure of the one-touch switch. For different vehicle door one-touch switches, the output pressure of the pressure reducing valve 230 can be adaptively adjusted according to the designed pressure. The solenoid valve 220 is electrically connected to the test controller 300. The solenoid valve 220 is also electrically connected to the test controller 300, which is used to control the opening and closing of the solenoid valve 220, and thus control relevant parameters such as the extension time, retraction time, and execution number of the needle cylinder 210 according to the actual test design requirements.

[0049] Furthermore, in order to improve the test efficiency, in other embodiments, the test bench 100 and the test controller 300 can be set to multiple, and controlled by the same test controller 300, so that durability tests can be carried out on multiple door one-touch switches at the same time, which has strong scalability.

[0050] In some alternative embodiments, the test bench 100 is further provided with an indicator light 310. The indicator light 310 is electrically connected to the exterior door handle 400 and the test controller 300. When the needle cylinder 210 presses the single-touch switch on the exterior door handle 400 and fully engages, the indicator light 310 turns on, thereby detecting whether the single-touch switch is fully engaged. If the single-touch switch is not fully engaged, that is, if the on-time of the indicator light 310 does not correspond to the preset extension and retraction times of the needle cylinder 210, the test controller 300 controls the various components of the test actuator 200 to cease operation and reports an error, thereby improving test accuracy.

[0051] The working principle of a durability test device for a one-touch door switch is as follows: when performing a durability test on a one-touch switch on an outer door handle, the outer door handle is installed on the bracket base plate 110, the positions of the two L-shaped angle codes 131 on the column 120 are adjusted, and the height and tilt angle of the mounting plate 140 are adjusted, so that the needle cylinder 210 on the mounting plate 140 is precisely aligned with the one-touch door switch, which facilitates durability testing of different types of one-touch door switches and improves test accuracy.

[0052] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
