Description

Technical Field

[0001] This utility model relates to the field of experimental testing of automotive electric mechanisms, and more specifically, to a testing device for vehicle electric mechanisms. Background Technology

[0002] With the increasing integration of functions into automotive multimedia screens, the number of mechanical buttons on traditional instrument panels and center consoles is gradually decreasing. This has led to some mechanisms requiring touchscreen or voice control for operation, such as the rear spoiler and pedals on some models, which lack physical buttons. To test the performance of these buttonless mechanisms, environmental durability testing is necessary. Since durability testing environments typically include extremely high and low temperatures, it is not suitable for operators to directly enter the vehicle for testing. Currently, the most common testing methods are unmanned testing.

[0003] There are several existing testing methods, such as periodically sending messages using CAN tools to test the switching durability of these mechanisms, playing recordings and then waking up the large screen for operation via voice, using robots with hand tools to simulate passenger finger touches on the large screen and control these mechanisms, or installing fixtures and multiple servo motors on the large screen, connecting the servo motors to a capacitive pen (or other materials that can trigger screen clicks), and controlling the movement of the servo motors through a program to achieve physical clicks on the large screen and complete the operation.

[0004] However, the above testing methods have problems such as inconvenient debugging, inconvenient maintenance, poor reliability, or limited applicability, and cannot meet the requirements for high efficiency and low cost of testing equipment. Utility Model Content

[0005] The purpose of this invention is to provide a vehicle electric mechanism testing device that can efficiently and cost-effectively perform performance testing on mechanisms without physical buttons.

[0006] The embodiments of this utility model are implemented as follows:

[0008] A control system, wherein the control system stores a preset program;

[0009] The click structure includes a capacitive click head corresponding to the first control. The first control is used to respond to the touch operation of the click head on the first control. The control system controls the electric mechanism to execute the preset program.

[0010] A power supply system for supplying power to the click structure.

[0011] In some embodiments, the test apparatus further includes a first cable, a female connector, and a junction box with a first mounting hole;

The two ends of the multiple second cables are respectively connected to the multiple click heads and the multiple female connectors, and the multiple click heads are respectively set to the positions of the multiple first controls.

[0016] In some embodiments, a first sealing structure is provided at the location where the first cable passes through the first mounting hole.

[0017] In some embodiments, the click structure is connected to the end of the second cable away from the junction box, and the second cable is provided with a second sealing structure at the location where the second mounting hole is located.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0031] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0033] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] With the increasing integration of functions into automotive multimedia screens, traditional mechanical buttons on instrument panels and center consoles are gradually disappearing. This has led to some mechanisms requiring touchscreen or voice control for operation, such as the rear spoiler and pedals on some models. Environmental durability testing of these mechanisms presents significant challenges. Currently, four main methods exist, each with its own drawbacks.

[0035] The first method, which uses CAN tools to periodically send messages to maintain the on / off durability of these mechanisms, has two significant drawbacks. First, the CAN channel needs an external interface. However, with the increasing prevalence of domain controller integration, many CAN channels are for internal use only and lack external interfaces. Second, it requires the vehicle model's DBC file. For OEM-owned models, this file is difficult to obtain due to confidentiality issues; for non-OEM models, there is no way to obtain it, making it impossible to achieve the function through CAN messages.

[0036] The second method involves playing a recording and then using voice to activate the large screen for operation. This method also has two drawbacks. First, the environmental temperatures in these durability tests typically include extremely high and low temperatures. Ordinary recording and playback devices generally lack the reliability required for such high environmental loads and are easily damaged, affecting test efficiency. Second, the high environmental load usually occurs within an environmental chamber, where the operating noise is very loud during the test, which also affects the accuracy of voice recognition, thus reducing test efficiency.

[0037] The third method uses a teaching robot equipped with hand tools to simulate passenger finger touches on a large screen, enabling manipulation of these mechanisms. This method offers high reliability and versatility, but it also has two drawbacks: first, the equipment is expensive, resulting in a poor return on investment, and many testing institutions currently lack this equipment; second, it requires removing interior parts such as seats and instrument panels to install the robot's base, leading to significant preparation work for the test.

[0038] The fourth method involves mounting fixtures and multiple servo motors on a large screen. These servo motors are connected to a capacitive pen (or other material capable of triggering screen clicks). The movement of the servo motors is controlled by a program to achieve physical clicks on the screen, completing the operation. However, the fixtures for this type of device have a limited range of applications; modifications are required to exceed this range, resulting in poor versatility. Secondly, because of the physical clicks involved, a significant amount of time is spent debugging program parameters to ensure the safety of the device and screen, leading to low efficiency.

[0039] refer to Figure 1 and Figure 2 As shown, Figure 1 This is a flowchart of the vehicle electric mechanism test device according to an embodiment of the present invention. Figure 2 This is a structural diagram of the junction box of the vehicle electric mechanism testing device according to an embodiment of this utility model. Figure 2The image only shows one second cable 6 and one male connector 7, but in reality, this application has multiple second cables 6 and multiple second male connectors 7. This application provides a vehicle electric mechanism testing device. The vehicle includes a display terminal 1, which displays a first control. The testing device includes a control system, a click structure, and a power supply system. The control system stores a preset program. The click structure includes a capacitive click head 2 corresponding to the first control. The first control is used to respond to the touch operation of the click head 2 on the first control. The control system controls the electric mechanism to execute the preset program. The power supply system supplies power to the click structure. The display terminal 1 can be an in-vehicle display screen, which can display test software icons and multi-level menus. The control system is pre-written with programs that need to test corresponding vehicle electric mechanisms, such as programs that control the vehicle's rear spoiler, pedals, and other electric mechanisms to perform the required test actions. The click head 2 is a capacitive click head, and the power supply system supplies power to the click head 2. When energized, the click head 2 undergoes capacitance changes. By controlling the duration of the power supply, long presses and short presses can be performed, thereby simulating a human finger clicking the test software icon to trigger the corresponding preset program, and thus controlling the vehicle's electric mechanism to perform corresponding actions. The entire test device can be adapted and installed in high and low temperature environment test equipment, thereby completing the control of electric mechanisms under various environmental conditions, and thus completing the test. It has the advantages of convenient debugging, convenient maintenance, high reliability, wide applicability, and high practical application value.

[0040] In some embodiments, the test apparatus in this embodiment further includes a first cable 3, a female connector 4, and a junction box 5 with a first mounting hole. One end of the first cable 3 is connected to the female connector 4, and the other end is connected to the control system and the power supply system through the first mounting hole. The female connector 4 is installed inside the junction box 5 and is connected to the control system and the power supply system via a cable, which can ensure stable signal transmission and is not easily affected by external interference.

[0041] In some embodiments, the test apparatus in this embodiment further includes a second cable 6 and a male connector 7, and the junction box 5 is provided with a second mounting hole. One end of the second cable 6 is connected to the male connector 7, which is used to connect to the female connector 4; the other end of the second cable 6 is connected to the click structure. The male connector 7 is installed inside the junction box 5 and is connected to the click structure through the cable, which can ensure stable signal transmission and is not easily affected by external interference. Moreover, the connection method of using the male connector 7 and the female connector 4 for plugging in makes installation and disassembly convenient and simplifies the assembly process.

[0042] In some embodiments, the number of female connectors 4, click heads 2, first controls, and second cables 6 in this embodiment are all multiple and the same. The two ends of the multiple second cables 6 are respectively connected to the multiple click heads 2 and the multiple female connectors 4. The multiple click heads 2 are respectively positioned corresponding to the multiple first controls. The first cable 3 can be a single cable or multiple cables equal to the number of second cables 6, but to save installation space, the first cable 6 is preferably a single cable. The multiple female connectors 4 are connected to the first cable 3 in a many-to-one manner, allowing the control system and power supply system to transmit signals to the multiple click heads 2 through a single cable. Simultaneously, the male connector 7 is connected to the female connector 4 in a one-to-one manner, enabling individual control of each click head 2.

[0043] In some embodiments, each male connector 7 and female connector 4 in this embodiment is a standard plug. The click head 2 adopts a universal interface with a diameter of about 3.5mm, which can be used immediately after plugging in and can be quickly replaced if damaged.

[0044] In some embodiments, the first cable 3 in this embodiment is provided with a first sealing structure 8 at the position of the first mounting hole. The sealing structure is connected to the end of the second cable 6 away from the junction box 5, and the second cable 6 is provided with a second sealing structure 9 at the position of the second mounting hole. The first sealing structure 8 and the second sealing structure 9 can be sealing rings, which can respectively realize the sealed connection between the first cable 3, the second cable 6 and the junction box 5, and can ensure the normal connection of the cables in extreme environments such as high temperature and high pressure, high humidity, and low temperature and low pressure.

[0045] In some embodiments, an adhesive pad is affixed to the position of the first control displayed on the display terminal 1 in this embodiment, and the click head 2 is bonded to the adhesive pad. The adhesive pad is made of a conductive material. The adhesive pad is a conductive material, such as conductive rubber, conductive silicone, or other composite materials, to prevent damage to the display terminal 1 caused by directly mounting the click head 2 on the display terminal 1. At the same time, during the simulation of finger clicking, the adhesive pad can buffer the clicking pressure, thus protecting the display terminal 1.

[0046] In some embodiments, adhesive tape is attached to the periphery of the pad in this embodiment. The tape strengthens the adhesion of the click head 2 to the display terminal 1, ensuring a stable connection of the click head 2 to the display terminal 1 even when the screen of the display terminal 1 is tilted at a large angle (e.g., 80°), thus preventing the click head 2 from falling off the display terminal 1.

[0047] In some embodiments, the area of ​​the adhesive pad's adsorption surface is determined based on the average area of ​​the target user's fingertip. The shape of the adhesive pad simulates the shape of a driver's or passenger's fingertip, and the overall shape can be set to a circle, square, etc. Each adhesive pad has a preset area, which is determined based on the average area of ​​the target user's fingertip, thereby enabling click simulation operations for different user groups (drivers or passengers).

[0048] In some embodiments, the test apparatus in this embodiment further includes an application software system, which is electrically connected to the control system and is used to write preset programs or modify the preset programs according to usage requirements. When it is necessary to control the simulated electric mechanism to perform a new action, the corresponding program is written or modified through that action, and the test apparatus does not need to be disassembled when writing or modifying the program, resulting in strong overall usability and adaptability.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
