Description

Technical Field

[0001] This utility model relates to the field of automotive electronics technology, and more specifically, to an automotive host aging test fixture and aging cabinet. Background Technology

[0002] In the automotive electronics industry, aging testing of automotive head units is a crucial part of the production process and a key inspection step, ensuring the quality of the manufactured head units. While automotive head units function normally initially when the vehicle is first installed, over time, prolonged exposure to high temperatures can cause surface melting and deformation of certain components, leading to serious damage. To perform aging testing on automotive head units, the head unit needs to be powered on and a video played. It is then placed in an aging chamber using an aging chamber fixture. The aging chamber contains aging chamber fixtures used to hold and secure the automotive head unit for aging testing. Current technology typically uses multiple bolts to secure the aging chamber fixtures. However, replacing these fixtures requires manually tightening the bolts each time, resulting in difficulties, excessive time consumption, and low efficiency. Utility Model Content

[0003] To address the problems of difficult, time-consuming, and inefficient replacement of existing aging test fixtures, this invention provides an automotive host aging test fixture and aging cabinet. The fixture body can be quickly replaced to adapt to different types of automotive host systems, with short replacement time, simple replacement process, improved replacement efficiency, and enhanced versatility of the aging cabinet.

[0005] In this technical solution, the automotive host aging test fixture includes a base and a fixture body. The base is fixedly installed in the aging chamber, and the fixture body is mounted on the base. The fixture body is used to fix and mount the automotive host for aging testing. The fixture body is slidably connected to the base, with the length direction of the base being a first direction, and the fixture body can slide off the base along this first direction. The base supports the fixture body, determining its vertical position. Horizontally, the fixture body can slide on the base along the first direction and can slide directly off the base, thus enabling disassembly and replacement to adapt to different automotive hosts. The fixture body is equipped with a locking component, and the base has a locking portion. The locking component connects with the locking portion to lock the relative position between the fixture body and the base, preventing the fixture body from sliding on the base and ensuring that the fixture body will not be displaced during subsequent automotive host aging tests, thus preventing any damage caused by misalignment.

[0006] Preferably, the locking element is a push-button quick-release pin, the locking part is a positioning hole opened on the base, and the push-button quick-release pin is inserted into the positioning hole.

[0007] Preferably, the base has two opposite sides extending upward to form a first side plate, and the bottom surface of the tooling body has two opposite sides installed with a second side plate. The second side plate is parallel to the first side plate, the top surface of the first side plate is slidably connected to the bottom surface of the tooling body, and two second side plates are disposed between two first side plates. The first side plate and the second side plate are slidably connected.

[0008] Preferably, the tooling body includes a base plate, which is slidably connected to the base. The upper surface of the base plate is fixedly mounted with a placement seat for placing the car host and a power supply device for supplying power to the car host.

[0009] Preferably, the power supply device has a plug-in terminal arranged along a first direction, and the automotive host aging test fixture further includes a drive component mounted on the base plate, the drive component being connected to the power supply device to push the plug-in terminal to move along the first direction.

[0010] Preferably, a slide rail is provided on the base plate along a first direction, a slider is mounted on the slide rail and slidably connected thereto, the power supply device is mounted on the slider, and the driving component is connected to the slider.

[0011] Preferably, the driving component includes a pull rod, a handle, and a crank rod arranged along a first direction. A first mounting base is provided on the base plate, and a sliding hole is provided on the first mounting base. One end of the pull rod passes through the sliding hole and is connected to the slider. A second mounting base is provided on the base plate. One end of the handle is rotatably mounted on the second mounting base via a rotating shaft. One end of the crank rod is rotatably connected to the other end of the pull rod, and the other end of the crank rod is rotatably connected to the handle. The connection point of the crank rod with the handle is located between the two ends of the handle.

[0012] Preferably, the upper surface of the placement seat is formed with a placement platform, and the placement platform extends upward from the side away from the vehicle host to form a third side plate for abutting against the side of the vehicle host.

[0013] Preferably, a mounting bracket is also fixedly installed above the base plate, and the upper surface of the mounting bracket is also provided with the placement seat and the power supply device.

[0014] Another aspect of this utility model provides an aging cabinet, including the aforementioned automotive host aging test fixture and a cabinet body, wherein the automotive host aging test fixture is fixedly installed inside the cabinet body.

[0015] In this technical solution, the aging cabinet includes a cabinet body and an aging test fixture. The cabinet body forms a closed space isolated from the outside world. The aging test fixture is installed in this closed space, and the vehicle host is installed in the aging test fixture. The cabinet body protects the aging test fixture and the vehicle host. At the same time, the closed space formed by the cabinet body isolates the aging test fixture and the vehicle host from the outside world, forming a relatively independent test environment.

[0024] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0025] Example 1

[0026] like Figure 1As shown, an automotive host aging test fixture includes a base 1, on which a fixture body 2 for mounting an automotive host 6 is disposed. The fixture body 2 is slidably connected to the base 1 along a first direction. A locking member 3 is disposed on the fixture body 2, and a locking portion 11 detachably connected to the locking member 3 is disposed on the base 1. When the locking member 3 is disengaged from the locking portion 11, the fixture body 2 slides relative to the base 1 along the first direction and detaches from the base 1. The automotive host aging test fixture includes a base 1 and a fixture body 2. The base 1 is fixedly installed in an aging chamber, and the fixture body 2 is disposed on the base 1. The fixture body 2 is used to fixally mount the automotive host 6 for aging testing. The fixture body 2 is slidably connected to the base 1, with the length direction of the base 1 being the first direction, allowing the fixture body 2 to slide off the base 1 along the first direction. The base 1 supports the fixture body 2, determining its vertical position. In the horizontal direction, the fixture body 2 can slide on the base 1 along the first direction, and the fixture body 2 can slide directly off the base 1, thereby achieving disassembly of the fixture body 2. A locking member 3 is provided on the fixture body 2, and a locking part 11 is provided on the base 1. The locking member 3 and the locking part 11 are detachably connected. The connection between the locking member 3 and the locking part 11 locks the relative position between the fixture body 2 and the base 1, preventing the fixture body 2 from sliding on the base 1. This ensures that during subsequent aging tests of the automotive host 6, no damage will occur due to displacement of the fixture body 2. Simultaneously, the detachable connection between the locking member 3 and the locking part 11 facilitates the release of the locking of the fixture body 2. When replacing the tool body 2, the worker first disassembles the locking piece 3 on the tool body 2, which was originally installed on the base 1, from the locking part 11, thus releasing the lock on the tool body 2. Then, the worker pulls the tool body 2 and slides it on the base 1, directly pulling the tool body 2 off the base 1, thereby disassembling the tool body 2. Next, the worker selects a suitable tool body 2, moves it onto the base 1, and pushes it to slide on the base 1 until it reaches the designated position on the base 1. At this point, the locking piece 3 on the tool body 2 aligns with the locking part 11 on the base 1. The worker then connects the locking piece 3 to the locking part 11, thus fixing the position of the newly installed tool body 2 and completing the replacement of the tool body 2.

[0027] like Figure 1As shown, the locking component 4 is a push-button quick-release pin, and the locking part 11 is a positioning hole on the base 1. The push-button quick-release pin is inserted into the positioning hole. The push-button quick-release pin is easy to operate; the extension and retraction of the pin end can be achieved by pressing the button, which improves the operating efficiency of the locking component 3. The pin end of the push-button quick-release pin faces the direction of the base 1. The locking part 11 is a positioning hole, and the pin end corresponds to the positioning hole on the base 1. After the pin end extends, it can be inserted into the positioning hole. At this time, the position of the pin end is restricted in the positioning hole, thus restricting the tooling body 2 from sliding beyond the range allowed by the positioning hole. When the pin end retracts, the pin end is pulled out of the positioning hole, and the positioning hole loses its restriction effect on the position of the pin end. At this time, the tooling body 2 can slide freely on the base 1 in the first direction.

[0028] like Figure 1 As shown, the base 1 has two opposite sides extending upward to form first side plates 12. The tooling body 2 has two opposite sides on its bottom surface with second side plates 21 installed. The second side plates 21 are parallel to the first side plates 12. The top surface of the first side plates 12 is slidably connected to the bottom surface of the tooling body 2. The second side plates 21 are positioned between the two first side plates 12, and are slidably connected to each other. The first side plates 12 function similarly to guide rails. In the vertical direction, the first side plates 12 abut against the tooling body 2, supporting it. In the horizontal direction, the tooling body 2 can slide on the top surface of the first side plates 12. Without restrictions, the sliding direction of the tooling body 2 is uncertain, and there is a possibility that the tooling body 2 may slip off the first side plates 12. The tooling body 2 has second side plates 21 installed on both sides of its bottom surface, positioned between the two first side plates 12. The second side plate 21 restricts the movement direction of the tooling body 2. The second side plate 21 is parallel to the first side plate 12, ensuring that the tooling body 2 can only slide along the length direction of the first side plate 12. When the sliding direction of the tooling body 2 deviates, the first side plate 12 cannot remain parallel to the second side plate 21. As the tooling body 2 slides, the first side plate 12 will come into contact with the second side plate 21, thereby restricting the deviation of the sliding direction of the tooling body 2.

[0029] Example 2

[0030] This embodiment is similar to Embodiment 1 above, except that, as Figure 1 As shown, the tooling body 2 includes a base plate 22, which is slidably connected to the base 1. The upper surface of the base plate 22 is fixedly mounted with a placement seat 23 for placing the car host 6 and a power supply device 24 for supplying power to the car host 6.

[0031] like Figure 3As shown, the power supply device 24 has a plug-in terminal 241 arranged along a first direction. The automotive host aging test fixture also includes a drive component mounted on a base plate 22. The drive component is connected to the power supply device 24 to push the plug-in terminal 241 to move along the first direction. The plug-in terminal 241 is used to plug into the automotive host 6, thereby connecting the circuit to power the automotive host 6 and driving the automotive host 6 to perform aging tests. The plug-in terminal 241 and the automotive host 6 are arranged along the first direction. The base plate 22 is also provided with a drive component, which is connected to the power supply device 24 to push the plug-in terminal 241 to move along the first direction. The operator can control the movement of the plug-in terminal 241 by controlling the drive component. When the drive component drives the plug-in terminal 241 to move closer to the automotive host 6, the plug-in terminal 241 will be inserted into the automotive host 6, realizing the connection of the circuit with the automotive host 6. When the drive component drives the plug-in terminal 241 to move away from the automotive host 6, the plug-in terminal 241 will be pulled out of the automotive host 6, disconnecting the connected circuit.

[0032] like Figure 3 As shown, a slide rail 242 is provided on the base plate 22 along a first direction. A slider 246 is mounted on the slide rail 242 and slidably connected thereto. A power supply device 24 is mounted on the slider 246, and a driving component is connected to the slider 246. The slider 246 is used to mount the power supply device 24. The slider 246 is slidably mounted on the slide rail 242, which restricts the slider 246 from sliding along the first direction, thereby restricting the sliding direction of the power supply device 24. The driving component is connected to the slider 246, and the driving component 246 drives the power supply device 24 to slide by driving the slider 246 to slide.

[0033] like Figure 3 , 4As shown, the driving component includes a pull rod 243, a handle 244, and a crank 245 arranged along a first direction. A first mounting base 13 is provided on the base plate 22, and a sliding hole is provided on the first mounting base 13. One end of the pull rod 243 passes through the sliding hole and is connected to the slider 246. A second mounting base 14 is provided on the base plate 22. One end of the handle 244 is rotatably mounted on the second mounting base 14 via a rotating shaft. One end of the crank 245 is rotatably connected to the other end of the pull rod 243, and the other end of the crank 245 is rotatably connected to the handle 244. The connection point of the crank 245 with the handle 244 is located between the two ends of the handle 244. The pull rod 243 and the slide rail 242 are also arranged along the first direction and are parallel to each other, ensuring that the sliding direction of the slider 246 driven by the pull rod 243 is consistent with the direction of the slide rail 242 and will not collide with the slide rail 242. A first mounting base 13 is provided on the base plate 22. The mounting base 13 has a sliding hole, and the pull rod 243 is slidably mounted on the sliding hole. The sliding hole restricts the pull rod 243 from sliding along the axial direction of the sliding hole, which is the first direction. A second mounting base 14 is also provided on the base 22. The second mounting base 14 has a handle 244, and a crank 245 is provided on the handle 244. The two ends of the crank 245 are rotatably connected to the handle 244 and the pull rod 243, respectively. The operator can drive the pull rod 243 to move by rotating the handle 244. When the handle 244 is rotated away from the pull rod 243, the handle 244 pulls the crank 245, which in turn pulls the pull rod 243 to move, driving the plug-in end 241 to be inserted into the car host 6. When the handle 244 is rotated towards the pull rod 243, the handle 244 pushes the crank 245, which in turn pushes the pull rod 243 to move, driving the plug-in end 241 to be pulled out of the car host 6. The crank 245 is used to convert the rotation of the handle 244 into linear motion along the first direction. The rotation of the handle 244 limits the range of motion of its drive lever 243, preventing the lever 243 from moving too much and causing the plug end 241 to collide with the car host 6 or slide out of the slide rail 242.

[0034] like Figure 2 As shown, a placement platform 231 is formed on the upper surface of the placement seat 23. A third side plate 232 extends upward from the side of the placement platform 231 away from the vehicle host 6, for contacting the side of the vehicle host 6. The placement platform 231 supports the vehicle host 6, and the vehicle host 6, under its own weight, is in close contact with the placement platform 231, thus determining the vertical position of the vehicle host 6. The third side plate 232 extends upward from the side of the placement platform 231 away from the vehicle host 6. When the vehicle host 6 is placed on the placement platform 231, the third side plate 232 abuts against the side of the vehicle host 6. By abutting against the side of the vehicle host 6, the third side plate 232 restricts the movement of the vehicle host 6, thereby determining the horizontal position of the vehicle host 6.

[0035] like Figure 1 As shown, a mounting bracket 4 is also fixedly installed above the base plate 22. The upper surface of the mounting bracket 4 is also provided with a placement seat 23 and a power supply device 24. By setting up the mounting bracket 4, the vertical space is fully utilized, allowing the aging test fixture to hold at least two automotive main units 6. The upper surface of the mounting bracket 4 is also provided with a placement seat 23 and a power supply device 24 for placing the automotive main units 6 and supplying power to them. This arrangement improves space utilization and allows for simultaneous aging tests on at least two automotive main units 6, thus improving testing efficiency.

[0036] Example 3

[0037] An aging chamber includes the aforementioned automotive host 6 aging test fixture and a cabinet, with the automotive host 6 aging test fixture fixedly installed inside the cabinet. The aging chamber includes the cabinet and the aging test fixture, wherein the cabinet forms a closed space isolated from the outside world. The aging test fixture is installed within this closed space, and the automotive host 6 is installed within the aging test fixture. The cabinet protects both the aging test fixture and the automotive host 6, while the closed space formed by the cabinet isolates the aging test fixture and the automotive host 6 from the outside world, creating a relatively independent testing environment and preventing errors in the aging test of the automotive host 6 due to interference from the external environment.
