Description

Technical Field

[0001] This utility model relates to the field of automotive screen testing technology, and in particular to an automotive screen testing fixture. Background Technology

[0002] With the rapid development of smart cockpits, in-vehicle entertainment equipment is becoming increasingly sophisticated. As a crucial form of in-vehicle entertainment, automotive screens offer passengers a superior audio-visual experience and enhance passenger comfort. After assembly, the automotive screen undergoes a series of programming and testing processes. During this process, it must be securely fixed to a test fixture to connect the test plug to the screen's USB interface. Existing test fixtures often employ clamping mechanisms to hold the screen in place from three sides. The test plug located on the side containing the USB interface automatically inserts into the interface. However, because the screen is completely secured, excessive force during insertion may damage the USB interface. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to design a test fixture for automotive screens, which can effectively solve the problem of damage to the automotive screen USB interface caused by excessive insertion force during the connection process between the test plug and the automotive screen USB interface.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A test fixture for automotive screens includes a base and several carrier units disposed on the base. Each carrier unit includes a carrier plate, a rectangular contour plate detachably disposed on the side of the carrier plate opposite to the base, a first clamping unit disposed at one end of the contour plate along its length, and a plug-in / pull-out unit disposed opposite to the first clamping unit and located at the other end of the contour plate along its length. The contour plate has a contour groove for placing an automotive screen. The first clamping unit includes a first clamping block slidably disposed on the carrier plate and an elastic element, one end of which is fixed to the carrier plate and the other end of which is connected to the first clamping block.

[0006] The automotive screen testing fixture designed in this scheme initially fixes the automotive screen by setting a contour plate with a contour groove. The sidewall of the contour groove restricts the movement of the automotive screen. In addition, the length of the contour groove is greater than the length of the automotive screen, so that the automotive screen can move along the length direction when placed in the contour groove. The first clamping unit is set at the end of the contour plate, and the first clamping block is slidably set on the carrier plate. Under the elastic force of the elastic element, it can abut against the automotive screen placed in the contour groove and press it tightly against the groove wall, realizing the final fixation of the automotive screen. Since the first clamping block relies on the elastic force of the elastic element to press the automotive screen, under the action of the reverse external force, the first clamping block can retract to realize the movement of the automotive screen. After the car screen is secured, the plug-in unit automatically approaches the screen and inserts the plug into its USB port. When the plug-in unit contacts the screen, the screen experiences a pushing force. Under significant force, the screen moves within a contoured groove to buffer the movement, transforming the rigid force between the plug-in unit and the screen into a gradually softened force, reducing the probability of damage to the screen's USB port. This design changes the conventional, completely restrictive fixing method for car screens, incorporating a buffered, restrictive fixing method in the direction of force applied to the plug. This effectively solves the problem of potential damage to the screen's USB port due to excessive insertion force during connection.

[0007] Furthermore, the first clamping unit also includes a sliding member disposed on the carrier plate, and the first clamping block includes a first clamp and a connecting block connected to the elastic member, the connecting block being disposed on the sliding member.

[0008] The sliding component uses a linear guide module, which is mounted on a carrier plate. A connecting block is mounted on the linear guide module, and a first clamp is mounted on the connecting block. The connecting block includes two connecting arms, which are located on both sides of the linear guide module and pass through the carrier plate to connect with the elastic component. Additionally, a silicone pad can be provided on the end face of the first clamp to effectively prevent scratches from contact between the first clamp and the automotive screen.

[0009] Furthermore, the contour plate is provided with a first notch that connects to the contour groove, and the end face of the first clamp facing the contour groove extends into the contour groove through the first notch.

[0010] When the elastic element is not compressed, the end face of the first clamp extends into the contour groove through the first notch. When the car screen is placed, the end face of the car screen first contacts the first clamp and squeezes the first clamp, and then the car screen is placed into the contour groove. The elastic element generates elastic force due to compression, so that the first clamp presses the car screen placed in the contour groove.

[0011] Furthermore, the plugging / unplugging unit includes a plug socket, a test plug disposed on the plug socket, and a plug drive that drives the plug socket closer to or further away from the profile plate.

[0012] The plug driver uses a drive cylinder, and the output end of the drive cylinder is equipped with a plug socket. The test plug is detachably installed on the plug socket by screws, which facilitates replacement when the test plug is damaged.

[0013] Furthermore, a second notch communicating with the contour groove is provided at the position opposite to the test plug on the contour plate.

[0014] By setting a second notch, the test plug, under the action of the plug driver, can extend into the contoured groove through the second notch and connect with the car screen.

[0015] Furthermore, it also includes a second clamping unit, which includes second clamps symmetrically arranged on both sides of the contour groove along the width direction, and a clamping drive member that drives the two second clamps to move closer or further apart, the clamping drive member being located below the carrier plate.

[0016] The test fixture can also be equipped with a second clamping unit. Two second clamps further restrict the car screen from both sides along its width, preventing significant displacement deviation in the width direction after the car screen is placed in the contour slot, which could prevent the test plug from being inserted into the car screen's USB port. Additionally, the second clamping unit improves the compatibility of the contour slot with smaller car screens. The two second clamps allow for centering of the small car screen within the contour slot, thus enabling car screen testing. Silicone pads can also be placed on the end faces of the second clamps to effectively prevent scratches from contact between the second clamps and the car screen.

[0017] Furthermore, a third notch communicating with the contouring groove is provided at the position opposite to the two second clamps on the contouring plate.

[0018] By providing a third notch, the second clamp, under the action of the clamping drive, extends into the contoured groove through the third notch to engage with the automotive screen. Additionally, the third notch facilitates the handling of the automotive screen by operators after the second clamp separates from it.

[0019] Furthermore, the second chuck has an avoidance notch on its end face facing the contour groove.

[0020] The side of the car screen has buttons such as power buttons and volume buttons. A clearance notch is provided on the end face of the second clamp to prevent the second clamp from interfering with the buttons when it comes into contact with the side of the car screen.

[0021] Furthermore, the base is also provided with a quick-release knob that can be connected and fixed to the testing machine, and the quick-release knob is located on the edge of the base.

[0022] The quick-release knob enables rapid installation and removal of the test fixture, thereby facilitating rapid mold change. When the test fixture needs to be replaced, the efficiency of mold change can be improved, the machine's uptime can be increased, and test output can be improved.

[0023] Furthermore, the base is also provided with a positioning pin, which is located at the edge of the base.

[0024] The base is also equipped with positioning pins that match the testing machine. These positioning pins enable the testing fixture to be quickly positioned on the mounting surface of the testing machine, thereby improving the efficiency of mold changing.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] The automotive screen testing fixture designed in this scheme initially fixes the automotive screen by setting a contour plate with a contour groove. The sidewall of the contour groove restricts the movement of the automotive screen. In addition, the length of the contour groove is greater than the length of the automotive screen, so that the automotive screen can move along the length direction when placed in the contour groove. The first clamping unit is set at the end of the contour plate, and the first clamping block is slidably set on the carrier plate. Under the elastic force of the elastic element, it can abut against the automotive screen placed in the contour groove and press it tightly against the groove wall, realizing the final fixation of the automotive screen. Since the first clamping block relies on the elastic force of the elastic element to press the automotive screen, under the action of the reverse external force, the first clamping block can retract to realize the movement of the automotive screen. After the car screen is secured, the plug-in unit automatically approaches the screen and inserts the plug into its USB port. When the plug-in unit contacts the screen, the screen experiences a pushing force. Under significant force, the screen moves within a contoured groove to buffer the movement, transforming the rigid force between the plug-in unit and the screen into a gradually softened force, reducing the probability of damage to the screen's USB port. This design changes the conventional, completely restrictive fixing method for car screens, incorporating a buffered, restrictive fixing method in the direction of force applied to the plug. This effectively solves the problem of potential damage to the screen's USB port due to excessive insertion force during connection. Attached Figure Description

[0033] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0034] like Figures 1 to 5As shown, this embodiment provides a test fixture for automotive screens, including a base 1 and a plurality of carrier units 2 disposed on the base. In this embodiment, five sets of carrier units 2 are arrayed on the base 1. In other possible embodiments, the number of carrier units 2 may be different, and no specific limitation is made here. The carrier unit 2 includes a carrier plate 21, a rectangular contour plate 22 detachably disposed on the side of the carrier plate 21 opposite to the base, a first clamping unit 23 disposed at one end of the contour plate 22 along the length direction, and a plug-in unit 24 disposed opposite to the first clamping unit 23 and located at the other end of the contour plate 22 along the length direction. The contour plate 22 is provided with a contour groove 221 for placing the automotive screen. The first clamping unit 23 includes a sliding member 233 disposed on the carrier plate 21, a first clamping block 231 mounted on the sliding member 233, and an elastic member 232. The first clamping block 231 includes a first clamp 2311 and a connecting block 2312. The elastic member 232 can be a spring, with one end fixed to the carrier plate 21 and the other end fixed to the connecting block 2312. The sliding member 233 can be a linear guide module, which is mounted on the carrier plate 21. The connecting block 2312 is mounted on the linear guide module, and the first clamp 2311 is mounted on the connecting block 2312. The connecting block 2312 includes two connecting arms, which are located on both sides of the linear guide module and pass through the carrier plate 21 to connect to the two elastic members 232 respectively. In addition, a silicone pad can be provided on the end face of the first clamp 2311 to effectively prevent the first clamp 2311 from being scratched by contact with the car screen. The plug-in / plug-out unit 24 includes a plug socket 241, a test plug 242 disposed on the plug socket 241, and a plug drive 243 that drives the plug socket 241 to move closer to or away from the profile plate 22. The plug drive 243 is a drive cylinder, the plug socket 241 is mounted on the output end of the drive cylinder, and the test plug 242 is detachably mounted on the plug socket 241 by screws, which facilitates replacement of the test plug 242 if it is damaged.

[0035] In this embodiment, the automotive screen testing fixture initially fixes the automotive screen by setting a contour plate 22 with a contour groove 221. The sidewall of the contour groove 221 restricts the movement of the automotive screen. In addition, the length of the contour groove 221 is greater than the length of the automotive screen, so that the automotive screen can move along the length direction when placed in the contour groove 221. The first clamping unit 23 is set at the end of the contour plate 22. The first clamping block 231 is slidably set on the carrier plate 21. Under the elastic force of the elastic member 232, it can abut against the automotive screen placed in the contour groove 221 and press it tightly against the groove wall to achieve the final fixation of the automotive screen. Since the first clamping block 231 presses the automotive screen by the elastic force of the elastic member 232, under the action of the reverse external force, the first clamping block 231 can retract to realize the movement of the automotive screen. After the car screen is secured, the test plug 242, driven by the plug driver 243, approaches the car screen and inserts into its USB interface. When the test plug 242 connects to the car screen, the screen experiences a pushing force from it. Under significant force, the screen moves within the contour groove 221 to buffer the movement, transforming the rigid force between the test plug 242 and the screen into a gradually softened force, thus reducing the probability of damage to the car screen's USB interface. This design changes the conventional fully restrictive fixing method for car screens, incorporating a buffered, restrictive fixing method in the direction of force application. This effectively solves the problem of potential damage to the car screen's USB interface due to excessive insertion force during the connection process.

[0036] like Figure 3 and Figure 4 As shown, the test fixture also includes a second clamping unit 25. The second clamping unit 25 includes second clamps 251 symmetrically arranged on both sides of the contour groove 221 along its width direction, and a clamping drive 252 that drives the two second clamps 251 to move closer or further apart. The clamping drive 252 is located below the carrier plate 21 and is a drive cylinder. The two second clamps 251 further restrict the car screen from both sides along its width direction, preventing large displacement deviations in the width direction after the car screen is placed in the contour groove 221, which would prevent the test plug 242 from being inserted into the car screen's USB interface. Furthermore, the second clamping unit 25 also improves the compatibility of the contour groove 221 with small-sized car screens. The two second clamps 251 enable centering of small-sized car screens within the contour groove 221, thus facilitating car screen testing. Silicone pads can also be provided on the end faces of the second clamps 251 to effectively prevent scratches from contact between the second clamps 251 and the car screen. The second clamp 251 has a clearance notch on its end face facing the contour groove 221. The side of the car screen has buttons such as power buttons and volume buttons. A clearance notch 253 is provided on the end face of the second clamp 251 to prevent interference between the second clamp 251 and the buttons when it contacts the side of the car screen.

[0037] like Figure 5 As shown, the contour plate 22 has a first notch 222 communicating with the contour groove 221. When the elastic member 232 is not compressed, the end face of the first clamp 2311 facing the contour groove 221 extends into the contour groove 221 through the first notch 222. When placing the car screen, the end face of the car screen first contacts and compresses the first clamp 2311, and then the car screen is placed into the contour groove 221. The elastic member 232 generates elastic force due to compression, causing the first clamp 2311 to press the car screen placed in the contour groove 221. The contour plate 22 also has a second notch 223 communicating with the contour groove 221 at the position opposite to the test plug 242. By setting the second notch 223, the test plug 242 can extend into the contour groove 221 and be inserted into the car screen through the second notch 223 under the action of the plug drive member 243. A third notch 224, connecting the contouring groove 221, is also provided at the position opposite to the contouring plate 22 and the two second clamps 251. By providing the third notch 224, the second clamps 251, under the action of the clamping drive member 252, extend into the contouring groove 221 through the third notch 224 and connect with the car screen. Furthermore, the third notch 224 also facilitates the handling of the car screen by operators after the second clamps 251 are separated from the car screen.

[0038] like Figure 1 and Figure 2 As shown, the base 1 is also equipped with quick-release knobs 11 that can be connected and fixed to the testing machine, and positioning pins 12 that match the testing machine. The quick-release knobs 11 and positioning pins 12 are located on the edge of the base 1, and their number is set according to the size of the base 1. In this embodiment, four quick-release knobs 11 and two positioning pins 12 are provided. The quick-release knobs 11 enable quick installation and removal of the test fixture, thereby enabling quick mold change. When the testing machine needs to change the test fixture, the efficiency of mold change can be improved, the machine's uptime can be increased, and the test output can be improved. In addition, the positioning pins 12 enable quick positioning of the test fixture on the mounting surface of the testing machine, thereby improving the efficiency of mold change.
