[0024] See Figure 1-2 An embodiment of the utility model provides a diagnostic device for diagnosing a car, the diagnostic device comprising a connector 1, a shell 2 and a circuit board 3; the connector 1 is assembled and connected to one end of the shell 2; the connector 1 is used to be electrically connected to the car; the shell 2 forms a receiving space, the circuit board 3 is assembled in the receiving space and is electrically connected to the connector 1; the circuit board 3 is connected to a point light source 4, the circuit board 3 is provided with a control module, and the point light source 4 is electrically connected to the control module; and, when the connector 1 is electrically connected to the car, the control module is used to control the point light source 4 to emit light of a preset color to the outside when preset conditions are met.

[0025] In an embodiment of the present invention, connector 1 is electrically connected to circuit board 3, and connector 1 can be used to electrically connect to a vehicle. Therefore, when a vehicle malfunctions, the vehicle can be electrically connected to connector 1, allowing circuit board 3 to detect the vehicle's fault signal. Circuit board 3 is also connected to point light source 4, which is electrically connected to a control module. Different colors of light emitted by point light source 4 represent different fault codes. Therefore, when the vehicle is electrically connected to connector 1 and circuit board 3 identifies the vehicle's fault code, the control module controls point light source 4 to emit light of a color corresponding to the fault code, which is then radiated externally. This arrangement allows the user to visually distinguish the difference in light color, allowing immediate access to fault information. Consequently, the user does not need to adjust the position of the diagnostic device; the device can be positioned at any position and angle. This allows the diagnostic device to adapt to cable lengths and connection locations, effectively preventing problems such as cable entanglement and loose connections. Furthermore, since fault information can be immediately identified based on the color of point light source 4, rapid diagnosis is also possible.

[0026] It should be noted that the embodiment of the present invention does not specifically limit the color of the light emitted by the point light source 4 corresponding to the fault code, and can be adaptively adjusted according to actual conditions. For example, red light emitted by the point light source 4 can represent an engine fault.

[0027] Furthermore, the point light source 4 is accommodated in the accommodation space, and the shell 2 is a transparent shell 2 ; or, the point light source 4 is exposed outside the shell 2 .

[0028] In some embodiments, the point light source 4 and circuit board 3 are both housed within the receiving space, and the housing 2 is transparent. Therefore, the user can directly see the light through the transparent housing 2 and immediately obtain fault information. Furthermore, because the point light source 4 is housed within the receiving space, i.e., it is supported, surrounded, and protected by the transparent housing 2, the present invention prevents the point light source 4 from external damage, effectively extending the service life of the point light source 4, compared to related art solutions in which the display screen of the diagnostic instrument is exposed to the outside world and may be damaged by being dropped.

[0029] It can be understood that in some embodiments, the circuit board 3 extends to the outside. Specifically, an opening can be set on the shell 2 so that the point light source 4 is exposed from the receiving space to the outside through the opening, and the user can also see the light and obtain fault information.

[0030] Furthermore, in some embodiments, the point light source 4 is directed toward the peripheral side of the housing 2 ; or, the point light source 4 is directed toward an end of the housing 2 away from the connector 1 .

[0031] Specifically, the point light source 4 is arranged on the circuit board 3. Regardless of whether the point light source 4 is located in the receiving space or exposed outside the shell 2, the main light-emitting direction of the point light source 4 can be changed by changing the placement position of the circuit board 3 on the shell 2.

[0032] In some specific embodiments, connector 1 is made of a non-transparent material, housing 2 is transparent, and point light source 4 is housed within the housing space and orthogonal to the surface of circuit board 3. Circuit board 3 is axially parallel to transparent housing 2. Point light source 4 can primarily emit light toward the periphery of transparent housing 2, meaning that the emitted light can radiate from the periphery of transparent housing 2 to the outside world. This arrangement reduces light obstruction by connector 1, allowing most of the light to pass through transparent housing 2 and reach the outside world, ensuring the effective illumination of point light source 4. From the user's perspective, the light emitted by point light source 4 is sufficiently bright that the user can immediately detect fault information based on the color of the light, thereby enhancing the user experience.

[0033] In addition, in some specific embodiments, the connector 1 is made of a non-transparent material, the housing 2 is a transparent housing 2, the point light source 4 is housed in the housing space and is orthogonal to the surface of the circuit board 3, the circuit board 3 is parallel to the axis of the transparent housing 2, the main light-emitting direction of the point light source 4 is toward the peripheral side of the transparent housing 2, and the point light source 4 is arranged on the circuit board 3 and at a certain distance from the connector 1. The greater the distance, the less light is blocked by the connector 1. Therefore, even if the main light-emitting direction of the point light source 4 is toward the peripheral side of the transparent housing 2, the position of the point light source 4 on the circuit board 3 and the distance between the point light source 4 and the connector 1 can be adjusted to avoid the light of the point light source 4 being blocked by the connector 1, thereby improving the illumination effect of the point light source 4 and further improving the user experience.

[0034] In some specific embodiments, connector 1 is made of a non-transparent material, housing 2 is a transparent housing 2, point light source 4 is housed within the housing space and is orthogonal to the surface of circuit board 3. Circuit board 3 is orthogonal to the axis of transparent housing 2. Point light source 4 can primarily emit light toward the end of transparent housing 2 away from connector 1. That is, light emitted by point light source 4 can radiate from the direction away from connector 1 through transparent housing 2 to the outside world. With this arrangement, virtually no light is blocked by connector 1, allowing all light to reach the outside world, thereby improving the illumination effect of point light source 4. From the user's perspective, the light emitted by point light source 4 is bright, allowing the user to immediately identify fault information based on the color of the light, thereby enhancing the user's user experience.

[0035] In addition, in some specific embodiments, the material of the connector 1 is a non-transparent material, the shell 2 is a transparent shell 2, the point light source 4 is accommodated in the accommodation space and is orthogonal to the surface of the circuit board 3, the circuit board 3 is orthogonal to the axis of the transparent shell 2, and the main light-emitting direction of the point light source 4 can be toward the end of the transparent shell 2 close to the connector 1, that is, the main light-emitting direction of the point light source 4 is toward the connector 1. At this time, since the radiation range of the point light source 4 is relatively wide, the user can also see the light emitted by the point light source 4 and the color of the light from the transparent shell 2, and can also identify and confirm the fault information.

[0036] Additionally, it should be noted that the embodiments of the present invention do not limit the point light source 4 to being orthogonal to the surface of the circuit board 3. In some implementations, the circuit board 3 has a certain thickness, and the point light source 4 can be positioned on the side of the circuit board 3. In this case, if the circuit board 3 is positioned parallel to the axis of the transparent housing 2, the point light source 4 can face away from the connector 1 or toward the connector 1. If the circuit board 3 is positioned orthogonal to the axis of the transparent housing 2, the light emitted by the point light source 4 is directed toward the circumference of the transparent housing 2. This can also achieve the desired illumination effect of the point light source 4, allowing the user to identify and confirm fault information. This will not be elaborated here.

[0037] Exemplarily, the point light source 4 may be an LED lamp bead.

[0038] Furthermore, in some specific embodiments, the shell 2 is provided with a clearance opening connecting the outside and the accommodation space, and the circuit board 3 is also connected to an electrical connector 5, and the electrical connector 5 is provided with an electrical connection interface. The electrical connector 5 is at the clearance opening, and the electrical connection interface is exposed to the outside, and the electrical connection interface is used for electrical connection with the outside.

[0039] Specifically, the electrical connector 5 can protrude from the housing space to the outside of the housing 2 through the clearance opening, wherein the electrical connector 5 can partially protrude from the clearance opening to ensure that the electrical connection interface of the electrical connector 5 is exposed to the outside. The electrical connection interface can be used for external electrical connection. Among them, the electrical connection interface can be connected to a charging device, so that the diagnostic device can be charged through the electrical connection interface. In some embodiments, the electrical connection interface can also be used to transmit signals, and can be connected to a display device, etc. through the electrical connection interface, so that fault information can be transmitted to the display device.

[0040] Exemplarily, the electrical connection interface may be a USB interface, a Type-C interface, and the like.

[0041] Furthermore, in some embodiments, the clearance opening is opened at an end of the housing 2 facing away from the connector 1 ; or, the clearance opening is opened at a peripheral side of the housing 2 .

[0042] Specifically, the electrical connection interface is parallel to the clearance port. By changing the position and direction of the clearance port, the position and direction of the electrical connection interface can be changed. This is not specifically limited in the present embodiment. The specific configuration can be based on the connector 1, circuit board 3, etc. For example, the electrical connection interface can be positioned a certain distance from the connector 1, or the electrical connection interface and connector 1 can be positioned at opposite ends of the housing 2, etc. Changing the position and direction of the electrical connection interface according to actual circumstances facilitates charging and signal transmission during actual use.

[0043] In addition, it is understandable that, depending on the electrical connector 5, the electrical connection interface can be provided at one end along the axial direction of the electrical connector 5, or at one end along the transverse direction of the electrical connector 5, etc.; and the axial direction of the electrical connector 5 can be provided parallel to the axial direction of the circuit board 3, or the axial direction of the electrical connector 5 can be provided orthogonal to the axial direction of the circuit board 3, etc. The embodiments of the present invention are not specifically limited.

[0044] Furthermore, in some embodiments, the shell 2 is formed by a coating process. Specifically, the shell 2 can be made by the coating process, and the connector 1 and the circuit board 3 can be coated with glue, so that the connection stability between the shell 2 and the connector 1, and the shell 2 and the circuit board 3 can be ensured; the sealing between the shell 2 and the connector 1, as well as the sealing between the yield port and the electrical connector 5 can be ensured, and the external moisture, dust, etc. can be prevented from entering the receiving space, so as to ensure the safety of the circuit and the service life of the diagnostic device. In addition, it can be understood that when the coating process is adopted, the connector 1 can adopt the existing connector 1, that is, the structure of the connector 1 is not limited, and the connector 1 can be provided with some assembly structures, such as the connector 1 can have a threaded structure, etc. The connector 1 can be directly coated with glue to form the shell 2, thereby improving practicality.

[0045] Exemplarily, the electrical connector 1 may be a 9-pin female connector 1 of model J1939 DT.

[0046] Furthermore, in some embodiments, the shell 2 includes a first rubber layer 21 and a second rubber layer 22 . The first rubber layer 21 surrounds the outer periphery of the second rubber layer 22 . The first rubber layer 21 and the second rubber layer 22 together define a receiving space.

[0047] Specifically, the encapsulation process can be performed in two steps, namely, a first encapsulation layer 21 and a second encapsulation layer 22. The first encapsulation layer 21 is wrapped around the outer periphery of the second encapsulation layer 22, thereby ensuring the required hardness of the housing 2. Furthermore, the second encapsulation layer 22 forms a partial receiving space. The first encapsulation layer 21 is higher in the axial direction than the second encapsulation layer 22. The first encapsulation layer 21 is wrapped around the outer periphery of the second encapsulation layer 22, and the two together form a receiving space for assembling the circuit board 3, etc., thereby improving the structural strength.

[0048] In some specific embodiments, the point light source 4 is arranged on the circuit board 3, and the point light source 4 and the circuit board 3 are housed together in the housing space. At this time, by enhancing the hardness of the shell 2, the protection of the point light source 4 and the circuit board 3 can be further enhanced, thereby improving the service life of the point light source 4.

[0049] Furthermore, in some embodiments, the housing 2 is made of TPE. Specifically, TPE (Thermoplastic Elastomer) is a novel polymer material intermediate between rubber and resin, offering advantages such as environmental friendliness, non-toxicity, and recyclability. Using TPE for encapsulation offers advantages such as ease of processing, environmental friendliness, non-toxicity, and excellent physical properties. Furthermore, products made of TPE offer a comfortable touch and excellent grip, meaning that the diagnostic device of the present invention can enhance the user experience.

[0050] Furthermore, in some embodiments, the connector 1 is provided with a first snap-fit ​​structure, the housing 2 is provided with a second snap-fit ​​structure, and the first snap-fit ​​structure is connected to the second snap-fit ​​structure. Specifically, the connector 1 and the housing 2 can also be assembled and connected in a detachable manner, and a stable connection between the connector 1 and the housing 2 can be achieved through the first snap-fit ​​structure and the second snap-fit ​​structure. In addition, an assembly position is provided in the receiving space, and the circuit board 3 can be assembled at the assembly position. In addition, a sealing structure is also provided between the connector 1 and the housing 2, and a sealing structure can also be provided between the electrical connector 5 and the clearance port, thereby improving the sealing between the structures, preventing external moisture, dust, etc. from entering the receiving space, ensuring circuit safety, and ensuring the service life of the diagnostic device.

[0051] Exemplarily, the first snap-fit ​​structure may be a snap-fit ​​groove provided on the outer side wall of the connector 1 , and the second snap-fit ​​structure may be a snap-fit ​​protrusion provided on the inner side wall of the shell 2 .

[0052] Furthermore, the outer circumference of the housing 2 may be provided with grooves, thereby increasing friction for the user to hold.

[0053] Furthermore, in some embodiments, the circuit board 3 is also provided with a signal detection module and a signal processing module. The signal detection module is connected to the signal processing module, and the signal processing module is connected to the control module. The signal detection module is used to send the detected signal to the signal processing module, and the signal processing module is used to process the signal and send it to the control module.

[0054] Specifically, when the car is connected to the connector 1, when the car has a fault, the signal detection module can detect the fault signal and transmit the fault signal to the signal processing module; then the signal processing module processes the signal and sends the signal to the control module; then the control module will control the point light source 4 to emit light of the corresponding color according to the fault code.

[0055] Furthermore, in some embodiments, the circuit board 3 may also be provided with a signal transmission module, the signal processing module may send the processed signal to the signal transmission module, and the user may transmit the fault signal to the display device through the electrical connection interface of the electrical connector 5.

[0056] Furthermore, in some embodiments, connector 1 includes terminals electrically connected to circuit board 3 and a terminal bracket fixedly connected to the terminals. The terminals are used to electrically connect to the vehicle, and at least a portion of the terminal bracket is located within housing 2. Specifically, the terminal bracket is connected to housing 2 and partially located within housing 2. The terminals are disposed on the terminal bracket and exposed to the outside, and the terminals are directly electrically connected to the vehicle's connection port to achieve signal transmission.

[0057] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0058] The above is a description of the technical solution provided by the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
