Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly and specifically limited.

[0034] Please refer to Figures 1-5 The present embodiment provides a vehicle lamp testing fixture 100 for electrode testing of a vehicle lamp panel 110, which comprises a base 111, a bottom plate 112 and a fixing plate 113, wherein the base 111 has a mounting cavity 11a; the bottom plate 112 is mounted in the mounting cavity 11a, and the bottom plate 112 is provided with a first electrical connection part; the fixing plate 113 is mounted in the mounting cavity 11a and located at the cavity opening of the mounting cavity 11a, and the fixing plate 113 is provided with a second electrical connection part; wherein when the vehicle lamp panel 110 is mounted in the mounting cavity 11a, the first electrical connection part is used for electrical connection with the electrode on the first side surface a1 of the vehicle lamp panel, and the second electrical connection part is used for electrical connection with the electrode on the second side surface a2 of the vehicle lamp panel; wherein the first side surface a1 is opposite to the second side surface a2.

[0035] In the design scheme of the conventional testing fixture, the part for testing the vehicle lamp panel 110 is usually arranged on the same side, which adopts a relatively conventional design. When the electrodes of the vehicle lamp panel 110 of the vehicle lamp are located on different sides, the conventional testing fixture cannot be directly applied because their design only considers the case of single-sided electrode. Therefore, during the mass production process, if the vehicle lamp with electrodes on different sides is encountered, the manufacturer often has difficulty in effectively performing the lighting test, which not only affects the efficiency of the production line, but also may cause problems in product quality control.

[0036] It can be understood that through the above design, the vehicle lamp test fixture 100 provided by the embodiment significantly improves the test efficiency and product quality control level in the mass production process; for the vehicle lamp panel 110 with electrodes on different sides, the test fixture overcomes the problem that the traditional fixture cannot be applied, ensuring that the vehicle lamp panel 110 with electrodes on different sides can be accurately tested; and by contacting the electrodes, the error caused by manual operation is reduced, the reliability of the test result is improved, and it is ensured that each vehicle lamp panel 110 is strictly tested, effectively avoiding product recall or customer complaints due to quality problems, and enhancing the market competitiveness of the product.

[0037] Preferably, in some embodiments, the first and / or second electrical connection part includes a metal protrusion 114, and the vehicle lamp test fixture 100 includes a wire 115 for connecting the metal protrusion 114 with the external power supply 211; it can be understood that in the implementation of a product, the first and second electrical connection parts can be provided as metal protrusions 114, and when the vehicle lamp panel 110 is installed in the installation cavity 11a, the metal protrusions 114 on both sides are abutted against the positive and negative electrodes on both sides of the vehicle lamp panel 110, thereby realizing the electrical connection of the positive and negative electrodes, and then the test can be performed.

[0038] Preferably, in some embodiments, the first and / or second electrical connection part includes a metal protrusion 114, and the vehicle lamp test fixture 100 includes a wire 115 for connecting the metal protrusion 114 with the external power supply 211; it can be understood that in the implementation of a product, the first and second electrical connection parts can be provided as metal protrusions 114, and when the vehicle lamp panel 110 is installed in the installation cavity 11a, the metal protrusions 114 on both sides are abutted against the positive and negative electrodes on both sides of the vehicle lamp panel 110, thereby realizing the electrical connection of the positive and negative electrodes, and then the test can be performed.

[0039] Preferably, in other embodiments, the first electrical connection part comprises a metal protrusion 114, and the second electrical connection part comprises a metal probe 116. This design combines two different types of electrical connection methods. Specifically, when the vehicle lamp panel 110 is installed in the mounting cavity 11a, the metal protrusion 114 is arranged on the bottom plate 112 and contacts the negative electrode 1112 on the back of the vehicle lamp panel 110; and the metal probe 116 is arranged on the fixing plate 113, with its end abutting against the positive electrode 1111 on the front of the vehicle lamp panel 110. The vehicle lamp testing fixture 100 is internally provided with wires 115, part of which is welded to the metal protrusion 114, and the other part is used to connect the metal probe 116 with the external power supply 211, ensuring that both can form good electrical connection with the external power supply 211. This design can adjust the electrical connection method according to the specific design of the vehicle lamp panel 110, and also improves the accuracy and efficiency of the test. In this way, stable and reliable abutment can be achieved for the positive and negative electrodes on both sides of the vehicle lamp panel 110, thereby achieving effective lighting test and ensuring that each product is strictly tested.

[0040] According to the above scheme, the third embodiment is selected, i.e., the first electrical connection part is arranged as a metal protrusion 114, and the second electrical connection part is arranged as a metal probe 116. It can be understood that the vehicle lamp panel 110 measured by the vehicle lamp testing fixture of the present embodiment is in an integral connection state with other vehicle lamp panels 110 after being produced as a finished product. In this state of structure, the vehicle lamp panel 110 is measured by using the metal probe 116 at the second electrical connection part, so that the metal probe 116 directly abuts against the positive electrode 1111 of the single vehicle lamp panel 110, thereby avoiding the structure of the metal protrusion 114, which causes the fixing plate 113 and the bottom plate 112 to be made of metal material and thus to be transmitted to other vehicle lamp panels 110 that have not been measured, further improving the accuracy of measuring the single vehicle lamp panel 110.

[0041] Preferably, the number of metal protrusions 114 is greater than or equal to the number of metal probes 116. It can be understood that according to the above scheme, the vehicle lamp panel 110 is a plurality of lamp panels spliced together. The purpose of this structural design is to enable the negative electrode 1112 on the spliced vehicle lamp panel 110 to be in abutment with each metal protrusion 114 after being assembled in the mounting cavity 11a, so that the number of metal protrusions 114 is set to correspond to the sum of the number of negative electrodes 1112 in the plurality of vehicle lamp panels 110. During the measurement process, the metal probe 116 is driven by the mechanical arm to abut against different positive electrodes 1111, so that the positive and negative electrodes of each vehicle lamp panel 110 can be tested for lighting.

[0042] Preferably, the wire 115 is connected to the metal protrusion 114 through one side of the base 111. Specifically, the wire 115 is inserted from one side of the base 111 and is fixed to the metal protrusion 114 on the bottom plate 112 by welding, which ensures the stable electrical connection between the wire 115 and the metal protrusion 114 and also makes the wiring of the test fixture simple. In addition, the connection between the wire 115 and the base 111 is sealed to prevent external dust and moisture from entering, thereby improving the durability and reliability of the system.

[0043] Preferably, the bottom plate 112 is installed at the bottom of the mounting cavity 11a, the fixed plate 113 is installed at the opening of the mounting cavity 11a, and the lamp plate 110 is installed between the bottom plate 112 and the fixed plate 113 and abuts against the bottom plate 112 and the fixed plate 113. Specifically, the bottom plate 112 is provided with metal protrusions 114 matched with the electrodes on the back of the lamp plate 110. When the lamp plate 110 is placed between the bottom plate 112 and the fixed plate 113, the positive electrode 1111 on the front face abuts against the metal probe 116 passing through the fixed plate 113, the negative electrode 1112 on the back face is tightly connected to the electrical connection part of the bottom plate 112, and the positive electrode 1111 on the top face is tightly connected to the electrical connection part of the bottom plate 112. The abutting force is generated by the abutting of the lamp plate 110 with the fixed plate 113 and the bottom plate 112, so that the lamp plate 110 can be stably placed during the electrode test, forming a complete circuit loop. This design not only ensures the stability and accuracy of the lamp plate 110 during the test, but also simplifies the installation steps and improves the test efficiency.

[0044] Preferably, the fixed plate 113 and the bottom plate 112 are made of metal at least at the positions of the positive and negative electrodes 1112 of the lamp plate 110. It can be understood that the purpose of designing the metal material is to conduct the conduction of the lamp plate 110, so as to conduct the signal transmitted by the electrode of the lamp plate 110 to the metal protrusion 114 through the metal material.

[0045] Preferably, the fixing plate 113 is installed flush with the cavity opening of the installation cavity 11a after installation; specifically, the fixing plate 113 is precisely adjusted to be flush with the cavity opening of the installation cavity 11a during installation, ensuring that its surface is flat and gapless; this design provides a supporting electrical contact surface for the vehicle lamp plate 110, and when the vehicle lamp plate 110 is placed between the bottom plate 112 and the fixing plate 113, the flush installation of the fixing plate 113 can ensure that the front surface of the vehicle lamp plate 110 is completely attached to the electrical connection part on the fixing plate 113, avoiding the problem of poor contact caused by the protrusion or depression of the fixing plate 113. In addition, the design of the fixing plate 113 flush with the cavity opening also facilitates the quick and accurate placement or removal of the vehicle lamp plate 110, and helps to protect the appearance of the vehicle lamp plate 110, preventing scratches or other damage caused by improper positioning of the fixing plate 113 during installation or removal, thereby ensuring product quality.

[0046] Preferably, the vehicle lamp testing fixture 100 further comprises a magnetic member 117, which is installed in the installation cavity 11a and is arranged on the side of the bottom plate 112 facing the bottom of the installation cavity 11a or on the side of the bottom plate 112 facing the cavity opening of the installation cavity 11a; specifically, the installation position of the magnetic member 117 is selected depending on the structure of the vehicle lamp plate 110 and the testing requirements. When the magnetic member 117 is located on the side of the bottom plate 112 facing the bottom of the installation cavity 11a, it can attract the metal part of the vehicle lamp plate 110 and the fixing plate 113 through magnetic force, ensuring that the vehicle lamp plate 110 is firmly attached to the electrical connection part on the bottom plate 112, and at the same time the fixing plate 113 also produces a relatively stable fixing effect, preventing displacement caused by slight vibration or external force, thereby ensuring the reliability of electrical contact during testing. Conversely, if the magnetic member 117 is arranged on the side of the bottom plate 112 facing the cavity opening of the installation cavity 11a, it can assist the fixing plate 113 to better compress the vehicle lamp plate 110, enhancing the overall fixing effect and ensuring that the front surface of the vehicle lamp plate 110 is in close contact with the electrical connection part on the fixing plate 113. In addition, the design of the magnetic member 117 also takes into account the need for easy disassembly, allowing for quick replacement of different types of vehicle lamp plates 110, improving testing efficiency.

[0047] Optionally, the magnetic member 117 in the present embodiment is provided as a magnet, which can be provided in a cylindrical shape in one embodiment, or in a strip shape in other embodiments.

[0048] Preferably, the bottom plate 112 is provided with an embedding groove 21a, and the magnetic member 117 is installed in the embedding groove 21a; specifically, the embedding groove 21a is designed at a specific position of the bottom plate 112, and the magnetic member 117 can be embedded in the embedding groove 21a and fixed inside the bottom plate 112, which not only makes the magnetic member 117 form an integral structure with the bottom plate 112, but also avoids the risk of loosening or displacement of the magnetic member 117 during use. When the magnetic member 117 is installed in the embedding groove 21a on the side facing the bottom of the mounting cavity 11a, the magnetic force generated thereby can effectively attract the metal part of the car lamp plate 110, ensuring that the back of the car lamp plate 110 is tightly attached to the electrical connection part on the bottom plate 112, and providing stable electrical contact. If the magnetic member 117 is installed in the embedding groove 21a on the side facing the opening of the mounting cavity 11a, the car lamp plate 110 can be better pressed by the auxiliary fixing plate 113, enhancing the contact effect of the front electrode.

[0049] In summary, the utility model provides a kind of car lamp test fixture, by above-mentioned design, the test efficiency and product quality control level of car lamp test fixture provided by the embodiment of the present application are significantly improved in batch production process;For the car lamp plate with electrode located in different sides, the test fixture overcomes the problem that traditional fixture cannot be applied, ensures that the car lamp plate with different side electrodes can be accurately tested;And by electrode contact, the error caused by manual operation is reduced, the reliability of test result is improved, ensures that each car lamp plate is tested strictly, effectively avoids product recall or customer complaint caused by quality problem, enhances the market competitiveness of product.
