[0030] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.
[0031] Reference below Figure 1-Figure 6A bench test device 10 for a vehicle according to an embodiment of the present application is described. The bench test device 10 includes a mounting frame 1, a tray assembly 2 and a connecting member 3. The mounting frame 1 is provided with multiple support plates 123 arranged at intervals in the height direction. The support plates 123 extend in the width direction and form a support surface on one side in the height direction. A rotating member 13 is provided at at least one end of the support plate 123 in the width direction. The tray assembly 2 is arranged on the mounting frame 1 and is suitable for fixing the controller. A limiting member 211 is provided at the free end of the tray assembly 2. One end of the connecting member 3 is connected to the outer peripheral wall of the rotating member 13, and the other end of the connecting member 3 is connected to the limiting member 211. The rotating member 13 can selectively rotate relative to the support plate 123 and pull the connecting member 3 to rotate the tray assembly 2 relative to the mounting frame 1 to switch between the expanded state and the stored state. In the expanded state, the tray assembly 2 abuts against the support surface. In the stored state, the angle between the tray assembly 2 and the mounting frame 1 is α and satisfies: 0<α<90°.
[0032] At present, the vehicle's ECU is an electronic component that needs to be fixed during bench testing to avoid slippage, skewing, and shaking due to loose fixation, which can affect the test. When there are many ECUs, the layout should be considered. If a bench is designed for each ECU, the cost will increase, and more space will be occupied when there are many benches.
[0033] Specifically, the bench testing device 10 may include a mounting frame 1 and a tray assembly 2. A support plate 123 may be provided on the mounting frame 1. The support plate 123 may be constructed in plurality, and the plurality of support plates 123 may be spaced apart in the height direction. The support plate 123 may be used to support the tray assembly 2. It should be noted that the length direction, width direction and height direction referred to in this application are all the length direction, width direction and height direction of the mounting frame 1.
[0034] The support plate 123 can extend in the width direction, and a support surface can be formed on one side of the support plate 123 in the height direction. The tray assembly 2 can be set on the mounting frame 1. Specifically, the tray assembly 2 can be used to limit and fix the controller to facilitate subsequent bench testing of the controller. It should be noted that the controller referred to here can be the vehicle's electronic controller, that is, the vehicle's ECU.
[0035] In a specific embodiment, the tray assembly 2 can be constructed in multiple numbers, and the multiple tray assemblies 2 can be arranged in one-to-one correspondence with the multiple support plates 123, and the correspondingly arranged tray assemblies 2 and support plates 123 are defined as a group, and each group of tray assemblies 2 and support plates 123 is spaced a certain distance from an adjacent group of tray assemblies 2 and support plates 123. The tray assembly 2 can selectively abut against the support surface, and since the mounting frame 1 can be provided with multiple support plates 123, the mounting frame 1 can be provided with multiple tray assemblies 2 for fixing multiple controllers, thereby increasing the number of bench test devices 10 that can be used, and improving bench test efficiency.
[0036] A rotating member 13 may be provided at at least one end of the support plate 123 in the width direction, a limiting member 211 may be provided at the free end of the tray assembly 2, and the bench testing device 10 may further include a connecting member 3, one end of the connecting member 3 may be connected to the outer peripheral wall of the rotating member 13, and the other end of the connecting member 3 may be connected to the limiting member 211, thereby connecting the rotating member 13 to the limiting member 211. Specifically, the connecting member 3 may be constructed as a pull wire, and the connecting member 3 may be optionally arranged around the outer peripheral wall of the rotating member 13.
[0037] Furthermore, the tray assembly 2 has an expanded state and a stored state, and the rotating member 13 can rotate relative to the support plate 123 to drive one end of the pull wire to move, and the other end of the pull wire can pull the tray assembly 2 and enable the tray assembly 2 to rotate relative to the mounting frame 1, thereby realizing the switching of the tray assembly 2 between the expanded state and the stored state. In the expanded state, the tray assembly 2 can abut against the support surface. At this time, the tray assembly 2 can maintain a horizontal state, and the controller can be placed on the tray assembly 2. When the tray assembly 2 fixes the controller, the controller can be bench tested. In the storage state, part of the pull wire can be arranged around the outer wall of the rotating member 13, and the angle between the tray assembly 2 and the mounting frame 1 is α, satisfying the relationship: 0<α<90°, that is, the angle between the tray assembly 2 and the mounting frame 1 can be any value between 0 and 90°. For example, the angle between the tray assembly 2 and the mounting frame 1 can be but not limited to 15°, 30°, 45°, 60°, etc. Such an arrangement can reduce the space occupied by the tray assembly 2. The smaller the angle between the tray assembly 2 and the mounting frame 1, the smaller the space occupied by the tray assembly 2 when not in use. Therefore, the bench test device 10 can place multiple controllers at the same time, and the bench test device 10 can switch between the expanded state and the storage state to reduce the space occupied by the tray assembly 2.
[0038] In short, the bench test device 10 of the embodiment of the present application has a mounting frame 1 and a tray assembly 2. The mounting frame 1 is provided with multiple support plates 123 that are spaced apart in the height direction. The support plates 123 can be used to support multiple tray assemblies 2, so that the mounting frame 1 can perform bench tests on multiple controllers, and when the tray assembly 2 is not in use, it can be switched from an expanded state to a stored state through the rotating member 13 and the connecting member 3, so that the space occupied by the tray assembly 2 is reduced, thereby reducing the overall space occupied by the bench test device 10.
[0039] In some embodiments of the present application, a mounting hole extending in the width direction may be formed in the support plate 123, and a first clamping portion may be formed on a portion of the inner wall of the mounting hole. The rotating member 13 may include a rotating shaft 131 and a rotating handle 132. A portion of the rotating shaft 131 may be disposed in the mounting hole, and another portion of the rotating shaft 131 may be fixedly connected to the connecting member 3. A second clamping portion may be formed on the rotating shaft 131 located in the mounting hole, and the rotating shaft 131 may be moved axially to achieve the matching or separation of the first clamping portion and the second clamping portion. It should be noted that when the first clamping portion and the second clamping portion are matched, the locking between the rotating shaft 131 and the support plate 123 can be achieved, and when the first clamping portion and the second clamping portion are separated, the locking between the rotating shaft 131 and the support plate 123 can be achieved. The support plates 123 are unlocked. When the tray assembly 2 is switched from the expanded state to the stored state, the rotating shaft 131 can be moved first to separate the first clamping part and the second clamping part. The rotating shaft 131 rotates and causes the connecting member 3 to surround the outer wall of the rotating shaft 131. After the other end of the connecting member 3 pulls the tray assembly 2 to a preset angle, the rotating shaft 131 is moved to match the first clamping part and the second clamping part to achieve locking between the rotating shaft 131 and the support part, thereby preventing the tray assembly 2 from pulling the connecting member 3 under the influence of gravity and improving the reliability of the connecting member 3. When the tray assembly 2 is switched from the stored state to the expanded state, the first clamping part and the second clamping part are separated by moving the rotating shaft 131, and then the rotating shaft 131 is rotated to make the tray assembly 2 abut against the support surface to achieve the expansion of the tray assembly 2.
[0040] In other embodiments, the mounting hole can penetrate the support plate 123 in the width direction, a portion of the rotating shaft 131 can be accommodated in the mounting hole, and a rotating handle 132 can be provided on both sides of the rotating shaft 131 in the width direction, and the connecting member 3 can be constructed into two and respectively fixed to both sides of the rotating shaft 131, thereby ensuring the stability of the tray assembly 2.
[0041] like Figure 2As shown, further, the rotating handle 132 can be set at one end of the rotating shaft 131 away from the support plate 123, and in the plane perpendicular to the width direction, the projection of the rotating shaft 131 is located inside the projection of the rotating handle 132, ensuring that the rotating shaft 131 can limit the moving distance of the rotating shaft 131, and the cross-section of the rotating handle 132 perpendicular to the width direction can be constructed as a polygon, for example, a square, pentagon, hexagon, etc., or the cross-section of the rotating handle 132 perpendicular to the width direction can be constructed as an irregular surface, and the surface of the rotating handle 132 can be provided with textures or protrusions to facilitate manual operation by the staff.
[0042] like Figure 1 As shown, in some embodiments of the present application, the mounting frame 1 may include a base 11 and a vertical plate 12, and the base 11 may be placed on the ground. Figure 5 and Figure 6 As shown, a roller assembly 111 may be further provided at the bottom of the base 11, and the roller assembly 111 may realize the movement of the mounting frame 1. Specifically, the roller assembly 111 may include a first support block 1111, a second support block 1112 and a roller 1113. The first support block 1111 and the second support block 1112 may be arranged on the side of the base 11 facing the ground, and the first support block 1111 and the second support block 1112 are arranged at intervals. A mounting shaft 1114 may be further provided between the first support block 1111 and the second support block 1112. The roller 1113 may be provided on the mounting shaft 1114 and may rotate relative to the mounting shaft 1114 to realize the movement of the mounting frame 1. The roller assembly 111 may also include a locking rod 1115, and the locking rod 1115 may be provided On the first support block 1111, and the end of the locking rod 1115 can be inserted into the first support block 1111, and a locking block 1116 can be provided at the end of the locking rod 1115, and the locking block 1116 can selectively contact or separate from the roller 1113 to achieve locking or unlocking of the roller 1113, and the roller assembly 111 can also include a support column 1117, and the support column 1117 can be set on the side of the first support block 1111 away from the second support block 1112, and the locking rod 1115 can be inserted into the support column 1117, and the support column 1117 can be used to support the horizontal movement of the locking rod 1115. Therefore, by controlling the locking rod 1115 to lock or unlock the roller 1113, the mounting frame 1 can be fixed to the ground or slide relative to the ground.
[0043] The vertical plate 12 can be arranged on the base 11, and the vertical plate 12 can extend in the height direction, and a support plate 123 can be arranged on one side of the vertical plate 12 in the width direction. The height of the vertical plate 12 can be determined according to the number of controllers that the bench test device 10 needs to fix.
[0044] Furthermore, on a plane perpendicular to the height direction, the projection of the vertical plate 12 can be located inside the projection of the base 11, and the vertical plate 12 can increase the overall height of the bench test device 10, thereby reducing the lateral space occupied by the bench test device 10, and the vertical plate 12 and the base 11 are arranged in the above manner to ensure that the tray assembly 2 can remain horizontal between the fixed controllers, so as to facilitate bench testing of the controller.
[0045] like Figure 2 As shown, in some embodiments of the present application, a mounting groove 121 recessed in the width direction is formed on the vertical plate 12, a limiting shaft 122 can be arranged in the mounting groove 121, the limiting shaft 122 can be extended in the length direction, and the limiting shaft 122 and the vertical plate 12 can be relatively fixed, a limiting hole portion 212 can be formed on the side of the tray assembly 2 facing the mounting frame 1, the limiting hole portion 212 can be sleeved on the outer periphery of the limiting shaft 122, and the limiting hole portion 212 is rotatably connected to the limiting shaft 122, so that the tray assembly 2 can rotate relative to the mounting frame 1.
[0046] like Figure 2 As shown, in some embodiments of the present application, the tray assembly 2 may include a tray body 21 and a fixing member 22, the tray body 21 may be set on the mounting frame 1, and the tray body 21 can be selectively rotated relative to the mounting frame 1, the tray body 21 can be used to carry a controller, and a limiting hole portion 212 may be formed on the side of the tray body 21 facing the mounting frame 1, and a limiting member 211 may be formed on the side of the tray body 21 away from the mounting frame 1, the fixing member 22 may be set on one side of the tray body 21 in the height direction, and the fixing member 22 may be selectively moved in the length direction or the width direction, or the fixing member 22 may be able to move in the length direction and the width direction, and the controller on the tray body 21 may be fixed by moving the fixing member 22.
[0047] In a specific embodiment, four fixing members 22 can be constructed, with two fixing members 22 spaced apart in the length direction and two fixing members 22 spaced apart in the width direction, so as to achieve fixation of the controller in four directions, thereby improving the fixing strength of the controller.

A limiting end surface 2222 may be formed at the end of the moving block 222. When the controller is placed on the tray body 21, the limiting end surface 2222 may be brought into contact with the controller by controlling the movement of the moving block 222, thereby limiting the controller and fixing the controller.

[0050] Specifically, the locking member 223 can move toward the moving block 222 and abut the locking end 2231 with the moving block 222 to achieve the function of limiting the movement of the moving block 222. When the locking member 223 moves in a direction away from the moving block 222 and separates the locking end 2231 from the moving block 222, the moving block 222 is unlocked.
