BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on the structures shown in these drawings without paying creative work.

[0026] Figure 1 This is a schematic diagram of the structure connection of the first embodiment of the wiper detection device of the utility model;

[0027] Figure 2 It is a schematic diagram of the structural connection of the second embodiment of the wiper detection device of the utility model.

[0028] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0029] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] The utility model embodiment provides a wiper detection device, referring to Figure 1 , Figure 1 It is a schematic diagram of the structural connection of the first embodiment of the wiper detection device of the utility model.

[0031] like Figure 1 As shown, in this embodiment, the wiper detection device includes: a controller 10 and a pin interface 20;

[0032] The controller 10 is connected to the pin interface 20, and the pin interface 20 is used to connect to the wiper M0;

[0033] The controller 10 is used to send a first test signal to the wiper M0 when the wiper M0 is connected through the pin interface 20, so as to perform a functional test on the wiper M0.

[0034] It should be understood that the functional test of the wiper M0 may at least include a wiper blade contact pressure test, a wiper M0 speed and angle adjustment test, and other tests that require the wiper M0 to repeatedly adjust the angle and apply pressure to the surface to be cleaned for friction, so as to verify the effectiveness of the wiper M0 in clearing rainwater. Therefore, when the wiper M0 is undergoing a functional test, it will repeatedly generate large-amplitude vibrations, affecting the electrical connection between the wiper M0 and the test access point. If there is a poor contact, the functional test may be interrupted, resulting in the inability to conduct a complete functional test, and multiple tests are required to ensure that all test data of the wiper M0 can be obtained. In addition, the above situation may also cause the test data of the wiper M0 to be abnormal, and it cannot be used as reliable and valid data.

[0035] It should be noted that the pin interface 20 is a multi-line interface fixed by a pin structure. Since it adopts a pin structure, it has high strength and rigidity and can withstand high-intensity loads and vibrations. When performing functional tests, the wiper M0 is fixed by the pin interface 20, which can ensure that the contact surface with the test access point will not be loosened due to large-scale vibrations in various functional tests of the wiper M0, effectively reducing the probability of test interruption due to poor contact during the test process, while also ensuring the reliability of the test data.

[0036] It is easy to understand that the pin interface 20 has at least a power supply line and a data line. When the wiper M0 is connected, the power supply line in the pin interface 20 can be used to transmit the electric energy provided by the controller 10 to the wiper M0, so that the wiper M0 enters a working state. In addition, the first test signal sent by the controller 10 can also be transmitted to the wiper M0 based on the data line in the pin interface 20, so that the wiper M0 in the working state can perform a corresponding functional test through the first test signal.

[0037] The utility model embodiment proposes a wiper detection device, the wiper detection device includes: a controller and a pin interface; the controller is connected to the pin interface, the pin interface is used to connect to the wiper; the controller is used to send a first test signal to the wiper when the wiper is connected through the pin interface, so that the wiper performs a functional test. The wiper is fixed by the pin interface, and the test contact point will not be loosened when the wiper is repeatedly shaken during the functional test, which reduces the probability of being unable to perform a complete test due to poor contact, improves the test efficiency, and also reduces the wear of the test contact point, saving costs.

[0038] Based on the first embodiment of the wiper detection device of the utility model, a second embodiment of the wiper detection device of the utility model is proposed, referring to Figure 2 , Figure 2 It is a schematic diagram of the structural connection of the second embodiment of the wiper detection device of the utility model.

[0039] like Figure 2 As shown, in this embodiment, the wiper detection device further includes: a marker 30;

[0040] The marker 30 is connected to the controller 10;

[0041] The controller 10 is further used to receive a test feedback signal sent by the wiper M0 when the wiper M0 is undergoing a functional test, and to send a corresponding product classification signal to the marker 30;

[0042] The marker 30 is used to mark the wiper M0 accordingly upon receiving the product classification signal.

[0043] It should be noted that, in the present embodiment, when the wiper M0 performs any test item of the functional test, the test data of the corresponding test item will be generated, and the wiper M0 can generate a corresponding test feedback signal based on the test data corresponding to each test item, and send the test feedback signal to the controller 10 through the data line of the pin interface 20. The controller 10 is provided with a memory inside, which stores the comparison thresholds of various test data. When the test feedback signal is received, the test data corresponding to the various test items of the wiper M0 can be obtained, and the obtained test data can be compared with the comparison threshold. According to the comparison result, it is detected whether the wiper M0 currently being tested is a qualified product or a defective product, and the corresponding product classification signal is sent to the marker 30 to mark the wiper M0 accordingly. In a specific implementation, if the controller 10 detects that the test data of the wiper M0 that has currently completed the test is higher than the comparison threshold, it outputs a corresponding product classification signal to the marker 30, and controls the marker 30 to mark the wiper M0 as a qualified product; if the controller 10 detects that the test data of the wiper M0 that has currently completed the test is lower than the comparison threshold, it outputs a corresponding product classification signal to the marker 30, and controls the marker 30 to mark the wiper M0 as a defective product.

[0044] It is worth noting that the marker 30 can mark the wiper M0 by electronic marking or physical marking. The physical marking method may include physical placement of plates, coloring, and other physical methods that can clearly distinguish qualified products from defective products.

[0045] Furthermore, in this embodiment, the controller 10 is also provided with a LIN port, and the LIN port is used to connect to the host computer 40;

[0046] The controller 10 is further used to forward the test feedback signal to the host computer 40 so that the host computer 40 can obtain the test data of the wiper M0.

[0047] It should be noted that, in this embodiment, the controller 10 also has a LIN port, and can exchange information with the host computer 40 at high speed and stability through the LIN bus. Through the LIN bus, the controller 10 can upload the test feedback signal to the host computer 40, so that when the host computer 40 receives the test feedback signal, it can directly obtain the test data of each test item of the corresponding wiper M0, which is convenient for users to trace the test data of the wiper M0.

[0048] Furthermore, in this embodiment, the controller 10 is further configured to send a second test signal to the wiper M0 upon receiving a test editing signal sent by the host computer 40 , so as to change the test items of the functional test.

[0049] It should be noted that the test items of the functional test of the wiper M0 can be adjusted based on the second test signal sent by the controller 10. In a specific implementation, the user can edit the test items of the functional test through the host computer 40 and generate a corresponding test editing signal. Based on the above-mentioned LIN port, the controller 10 can also receive the test editing signal transmitted by the host computer 40, and send the corresponding second test signal to the wiper M0 based on the received test editing signal to change the test items of the functional test of the wiper M0.

[0050] Furthermore, in this embodiment, the wiper detection device further includes: a power supply module 50;

[0051] The power supply module 50 is connected to the controller 10;

[0052] The power supply module 50 is used to output a power supply signal to the controller 10;

[0053] The controller 10 is further configured to supply power to the wiper M0 when receiving the power supply signal and connected to the wiper M0 through the pin interface 20 .

[0054] It should be noted that, in this embodiment, the wiper detection device can independently power the wiper M0, and an independent power supply module 50 is arranged inside it. As long as there is electrical energy inside the power supply module 50, it will output a power supply signal to the controller 10 to provide power for the controller 10.

[0055] In a specific implementation, upon receiving the power supply signal sent by the power supply module 50 , the controller 10 can directly power the connected wiper M0 , without the need for the wiper M0 to be additionally connected to other external power sources.

[0056] Furthermore, in the present embodiment, the pin interface 20 has a variety of interface shapes, and each of the pin interfaces 20 of the interface shape corresponds to a wiper M0 of a certain interface shape.

[0057] It should be understood that, in a specific implementation, there are multiple types of wiper M0 products, and various types of wiper M0 correspond to interfaces of different shapes. Correspondingly, interfaces of different shapes are required to be electrically connected to the corresponding types of wiper M0.

[0058] It is easy to understand that the pin interface 20 is very easy to install and disassemble, and is convenient for replacement. In this embodiment, pin interfaces 20 of various interface shapes can be pre-stored. When it is necessary to perform functional tests on wipers M0 of different product types, the pin interface 20 of the corresponding interface shape can be quickly disassembled and replaced, so that the interface shape of the wiper detection device still matches the wiper M0 to be tested. There is no need to replace the controller 10. Only by replacing the pins of the corresponding interface shape, the test devices of various wipers M0 can be quickly changed, which is compatible with the testing of various wipers M0 and saves costs.

[0059] Further, in this embodiment, the wiper detection device further includes: a plurality of pin interfaces 20;

[0060] Each of the pin interfaces 20 is connected to the controller 10, and each of the pin interfaces 20 is used to access a corresponding wiper M0;

[0061] The controller 10 is further configured to send the first test signal to each wiper M0 when each wiper M0 is connected via each pin interface 20 , so as to perform a functional test on each wiper M0 .

[0062] It should be noted that, in this embodiment, the controller 10 uses multiple channels to connect to multiple pin interfaces 20, which can simultaneously perform functional tests on the wipers M0 connected to multiple pin interfaces 20, greatly improving the test efficiency and saving time costs. In this embodiment, the number of pin interfaces 20 that can be connected to the same controller 10 does not exceed eight.

[0063] In addition, to achieve the above-mentioned purpose, the utility model also proposes a wiper detection device, which adopts the wiper detection device as described above. Since the wiper detection device of the utility model adopts all technical solutions of all embodiments of the wiper detection device as described above, it at least has all the beneficial effects of the wiper detection device as described above, which will not be described one by one here.
