On the contrary, these embodiments are provided to make the present application more thorough and complete, and to fully convey the scope of the present application to those skilled in the art.

[0024] It should be understood that although the terms "first", "second", "third", etc. may be used in this application to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this application, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more unless otherwise specifically defined.

[0025] Unless otherwise clearly specified and defined, terms such as "installed", "connected", "linked", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] In the related art, if there is a slight breakage in the ITO pattern, the signal can still be sent to the touch screen test device, which may lead to misjudgment and thus defective products flowing out.

[0027] In view of the above problems, the embodiments of this application provide a vehicle-mounted touch screen test device, which can accurately screen out defective vehicle-mounted touch screens and improve the accuracy of the test.

[0028] The technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0029] Please refer to Figures 1 to 4 , a vehicle-mounted touch screen test device, including: a base 100, a pressing component 200, a conduction component 300 and a conductive plate 400. There are a first groove 110 and a second groove 120 on the base 100; the pressing component 200 is arranged on the base 100, and the pressing component 200 is located above the second groove 120; the conduction component 300 is arranged on the base 100; the conductive plate 400 is arranged in the first groove 110.

[0030] It should be understood that the current test process is usually to power on the touch screen, transmit an electrical signal to the test main board, connect the test main board to the intelligent terminal, and display the strength of the electrical signal of the sensor ITO pattern through the APP of the intelligent terminal to facilitate the operator to observe whether the ITO pattern is damaged.

[0031] It should be noted that the pressing component 200 is used to press down the FPC board of the touch screen to make it conductive with the conducting component 300, so that the electrical signal is transmitted to the APP of the smart terminal for display. Furthermore, by setting the conductive plate 400, the conductive plate 400 is located below the touch screen. The setting of the conductive plate 400 can increase the electromagnetic wave induction of the touch screen, that is, the magnetic induction intensity, and then the electrical signal of the touch screen can be amplified. When the amplified electrical signal is transmitted to the terminal, the operator can intuitively judge whether the ITO pattern of the touch screen has a slight short circuit or open circuit. That is, the conductive plate plays the role of amplifying the signal.

[0032] See also Figure 1 In one embodiment, the pressing assembly 200 includes a supporting plate 210, a rotating rod 220 and a supporting column 230, the supporting plate 210 is arranged on the supporting column 230, the rotating rod 220 is arranged on the supporting plate 210, the supporting column 230 is arranged on the base 100, and the supporting plate 210 is located above the second groove 120.

[0033] It should be noted that, by toggling the rotating rod 220 , the supporting plate 210 is pressed down along the supporting column toward the second groove 120 .

[0034] See also Figure 1 and Figure 2 In one embodiment, the conduction component 300 includes a probe 310, and a through hole is formed at the bottom of the second groove 120, and the probe 310 passes through the through hole. Specifically, the conduction component 300 also includes a test mainboard, which is disposed on the base 100, and the probe 310 is disposed on the test mainboard. Specifically, the conduction component 300 also includes a wire harness plug interface 320, which is disposed on the base 100, and the wire harness plug interface 320 is electrically connected to the test mainboard.

[0035] It should be noted that the probe 310 is used to conduct with the FPC board of the touch screen, and the test mainboard is used to receive the electrical signal of the touch screen, and then transmit it to the smart terminal through the external wire of the harness plug interface 320. The test mainboard is arranged inside the base 100.

[0036] See also Figure 1 In one embodiment, a material taking trough 130 is also provided on the base 100 .

[0037] It should be understood that the provision of the material taking slot 130 facilitates taking the touch screen.

[0038] See also Figure 1 In one embodiment, it also includes a limit block 500 , which is disposed on the base 100 .

[0039] It should be noted that a plurality of limiting blocks 500 are provided and are arranged around the touch screen for limiting the touch screen.

[0041] It should be noted that the material of the conductive plate 400 can be copper foil or other conductive metals, and the setting of the insulating film 600 can prevent the conductive plate 400 from directly contacting the touch screen.

[0042] Please refer to Figure 1 , in one embodiment, an avoidance opening 140 is further formed on the base 100.

[0043] It should be understood that the setting of the avoidance opening 140 is to facilitate the operator to pick up and place the base 100.
