[0046] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0047] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion.

[0048] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0049] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0050] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0051] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0052] An automotive diagnostic tool is a specialized device used to detect and analyze the operating status and fault information of automotive electronic systems. It is typically an industrial panel PC, and because it plays a major role in the automotive diagnostic process, it is also called a host computer or diagnostic device. It usually includes a main control unit, a communication interface unit, a power management unit, a storage unit, and a display unit. The main control unit, including the MCU, is the brain of the diagnostic tool, mainly responsible for data processing, protocol interpretation, and command sending and receiving. It typically uses a high-performance embedded microprocessor and supports multi-protocol decoding. The communication interface unit may include an OBD-II interface plug for connecting to the vehicle's standard OBD-II diagnostic connector, and usually supports the CAN bus service protocol for communication with the vehicle. The power management unit provides power to the diagnostic tool and has built-in voltage regulation circuitry to protect the device from voltage fluctuations. The storage unit includes Flash and RAM; some diagnostic tools also have SD cards or eMMC for storing diagnostic records, vehicle data logs, etc. The display unit includes a screen or touchscreen, indicator lights, etc., for displaying menus, fault codes, data flow charts, etc.

[0053] When some special components of a vehicle malfunction, such as the air conditioner, specialized air conditioner repair tools are required. However, due to the low visibility of these tools, fault diagnosis relies entirely on the experience and skills of the repair personnel. Misdiagnosis can not only affect the user experience but also pose a safety hazard.

[0054] With the development of the automotive industry, people have higher requirements for the accuracy of repairs. To meet the long lifecycle requirements of customer vehicles, this applicant proposes connecting automotive diagnostic tools and air conditioning repair tools, such as manifolds, so that the data obtained by the air conditioning repair tools can be analyzed and visualized through the automotive diagnostic tool, thereby improving repair efficiency. These air conditioning repair tools are typically referred to as slave devices or auxiliary equipment. Currently, to achieve seamless integration between the automotive diagnostic tool and the air conditioning repair tools, two separate devices are usually required for independent diagnosis and testing before data analysis. This makes it difficult to effectively combine the two, resulting in significant inconvenience.

[0055] In view of this, embodiments of this application propose a connection component, as well as a diagnostic device, auxiliary device, and diagnostic system employing this connection component. The purpose of this connection component is to achieve a convenient, quick, and integrated automatic locking connection between the diagnostic device and the auxiliary device. By setting a sliding unit and a sliding plate capable of automatic sliding locking, when the diagnostic device and the auxiliary device are connected, the sliding unit can automatically lock the diagnostic device and the auxiliary device together to form a fully functional diagnostic system, requiring no manual operation, which is very convenient. When the diagnostic device or the auxiliary device needs to be used independently, the sliding unit can be slid, and the sliding plate will automatically unlock the connection between the diagnostic device and the auxiliary device, quickly separating the two. The connection component proposed in this application embodiment greatly facilitates the connection and separation between the diagnostic device and the auxiliary device, effectively solving the problem of the two devices being unable to be used together.

[0056] It should be noted that the connecting components proposed in this application can be applied to various products and systems that require combined use, and are not limited to diagnostic equipment. This application only uses vehicle diagnostic equipment as an example for illustration and is not intended to limit the scope of protection of this application. Furthermore, the diagnostic equipment and auxiliary equipment proposed in this application are merely used to distinguish different equipment entities. The auxiliary equipment can be a manifold or other testing equipment. In this application embodiment, the connecting components can be disposed on the diagnostic equipment or the auxiliary equipment, and are not intended to limit the scope of protection of this application.

[0057] like Figure 1The diagram shows the overall structure of the connecting assembly proposed in this application embodiment. The connecting assembly 12 includes a sliding bracket 124, a sliding unit 123, and a sliding plate 122. The sliding bracket 124 has a sliding cavity 1242, and the sliding unit 123 is disposed within the sliding cavity 1242. A first sliding hole 1243 is provided on one side of the sliding bracket 124 opposite to the sliding cavity 1242 in a first direction. The sliding bracket 124 also has a pin hole 1241 in the first direction. The sliding unit 123 includes a sliding seat 1230, and a first elastic element 1232 is provided on one side of the sliding seat 1230 in a second direction. One end of the first elastic element 1232 is connected to the sliding unit 123. The movable seat 1230 is fixedly connected, and the other end of the first elastic member 1232 abuts against the inner wall of one side of the sliding cavity 1242, which is used to drive the sliding seat 1230 to slide in the sliding cavity 1242; the sliding plate 122 is disposed on the side of the sliding bracket 124 close to the first sliding hole 1243 in the first direction, and is fixedly connected to the sliding seat 1230 through the first sliding hole 1243; the sliding plate 122 slides freely relative to the sliding bracket 124 under the drive of the sliding seat 1230; a snap-fit ​​hole 1221 is provided on the sliding plate 122 at a position opposite to the pin hole 1241 on the sliding bracket 124, and a snap-fit ​​part 1222 is provided in the snap-fit ​​hole 1221.

[0058] Continue to refer to Figure 1 To facilitate the explanation of the structure of this connecting component, different coordinate axes are first defined in this embodiment, such as... Figure 1 As shown, the X-axis direction is defined as the first direction, the Y-axis direction as the second direction, and the Z-axis direction as the third direction. Typically, the first, second, and third directions are preferably perpendicular to each other. However, in practical applications, the first, second, and third directions can also form an angle; they do not necessarily have to be a 90-degree angle, as long as the purpose of this invention is achieved.

[0059] exist Figure 1In this connection assembly 12, the sliding bracket 124, the sliding unit 123, and the sliding plate 122 are the three main components. The sliding bracket 124 provides overall fixation and support for the connection assembly, defining its structure. When the connection assembly is connected to an auxiliary device, mounting holes can be provided on the sliding bracket 124, allowing connection to the auxiliary device via screws, rivets, or snap-fits, thus fixing the connection assembly to the auxiliary device. The sliding unit 123 and the sliding plate 122 cooperate to form the locking and unlocking mechanism of the connection assembly. They are mounted on the sliding bracket 124 and can slide relative to it, thereby fixing the diagnostic device 10 and the auxiliary device 20 together.

[0060] For the specific structure of the connecting component 12, please refer to [link / reference needed]. Figure 2 The sliding bracket 124 has a compact, elongated structure. To facilitate the connection between the connecting components and the auxiliary equipment, different connection holes can be provided at different positions on the sliding bracket 124 without affecting the connection function. These connection holes can be located in a first direction or a second direction. Furthermore, to adapt to different structures of the auxiliary equipment, the sliding bracket 124 can be configured in various shapes and structures without compromising the connection function. The sliding bracket 124 can be made of plastic, wood, or metal, and can be integrally molded or composed of multiple connected parts. For the connection function, the interior of the sliding bracket 124 is hollow, forming a sliding cavity 1242 to accommodate the sliding unit 123. To facilitate the connection between the sliding unit 123 and the sliding plate 122, in this embodiment, a first sliding hole 1243 is provided on the sliding bracket 124 in the first direction. The first sliding hole 1243 is positioned opposite to the sliding cavity 1242 and the two are in a communicating state. That is, when the sliding unit 123 slides within the sliding cavity 1242, a portion of the structure extends out of the sliding cavity 1242 through the first sliding hole 1243. In this embodiment, the first sliding hole 1243 is used to connect the sliding unit 123 and the sliding plate 122. Meanwhile, continuing to refer to... Figure 2To facilitate connection between different devices, a pin hole 1241 is provided on one side of the sliding cavity 1242 in the first direction. This pin hole 1241 penetrates the body of the sliding bracket 124 and is primarily used for the insertion of the auxiliary device 20, enabling connection between the diagnostic device 10 and the auxiliary device 20. In practical applications, the pin hole 1241 can be positioned on one side or both sides of the sliding cavity 1242 as needed, allowing for symmetrical fixation of the auxiliary device 20. Besides facilitating device connection, the pin hole 1241 can also house signal lines. A female connector can be provided in the pin hole, and a male connector can be provided on the pin of the auxiliary device. When the pin 211 of the auxiliary device is inserted, the pin 211 and the pin hole 1241 connect via the male and female connectors, achieving signal connection. This enables both physical and electrical connections between different devices. Of course, the diagnostic device and the auxiliary device can also communicate with each other via Bluetooth, WiFi or other means.

[0061] The sliding unit 123 includes a sliding seat 1230 and a first elastic element 1232. (Continuing to refer to...) Figure 2 and Figure 3 , Figure 3 This is an exploded view of the sliding unit 123. The sliding seat 1230 is a block structure, constituting the main body of the sliding unit 123. The sliding seat 1230 is located inside the sliding cavity 1242, and a second fixing hole 1237 is provided on one side in the second direction. One end of the first elastic member 1232 is fixedly disposed in the second fixing hole 1237. The first elastic member 1232 is also accommodated in the sliding cavity 1242, and its end away from the sliding seat 1230 abuts against the inner wall of the sliding cavity 1242. When the sliding seat 1230 slides in the reverse direction in the second direction, the sliding seat 1230 squeezes the first elastic member 1232, so that the first elastic member 1232 is in a compressed state. When the sliding seat 1230 slides in the forward direction in the second direction, the elastic force of the first elastic member 1232 acts on the sliding seat 1230 to drive the sliding seat 1230 to slide in the sliding cavity 1242. In this embodiment, the forward sliding and the reverse sliding are relative states. The forward sliding is sliding to the left in the direction of the second direction, and the reverse sliding is sliding to the right in the direction of the second direction.

[0062] Continue to refer to Figure 3A sliding plate 122 is provided on the side of the sliding bracket 124 near the first sliding hole 1243 in the first direction. The sliding plate 122 and the sliding seat 1230 are fixedly connected within the first sliding hole 1243. That is, at the fixed connection point of the first sliding plate 122 and the sliding seat 1230, the sliding plate 122 slides freely within the first sliding hole 1243 under the action of the sliding seat 1230. The sliding seat 1230 and the sliding plate 122 are relatively fixed and can slide freely relative to the sliding bracket 124 within the sliding cavity 1242. Figure 3 As shown, a fixing hole can be provided on the end face of the sliding seat 1230 facing the sliding plate 122, and a screw can be provided on the sliding plate 122 to fix the sliding plate 122 and the sliding seat 1230 together by screwing. Alternatively, they can be fixed together by adhesive or snap-fit, etc., which is not limited in this application. The main function of the sliding plate 122 is to fix the pin 211 of the auxiliary equipment. Therefore, a snap-fit ​​hole 1221 is provided on the sliding plate 122 at a position opposite to the pin hole 1241 of the sliding bracket 124. Figure 4 The diagram shows the structure of the snap-fit ​​hole 1221 on the connecting plate. The snap-fit ​​hole 1221 can be configured as a gourd structure, where the inner diameter of one side is smaller than the inner diameter of the other side. The side with the smaller inner diameter forms the snap-fit ​​portion 1222. To achieve snap-fit ​​with the auxiliary device, the inner diameter of the snap-fit ​​portion 1222 is generally smaller than the inner diameter of the pin 211 of the auxiliary device, and the inner diameter of the portion outside the snap-fit ​​portion 1222 is generally larger than the inner diameter of the pin 211 of the auxiliary device. When... When the latching portion 1222 of the sliding plate 122 abuts against the pin 211 of the auxiliary device, the latching portion 1222 can latch the pin 211 of the auxiliary device, thereby fixing the auxiliary device. When the latching portion 1222 of the sliding plate 122 separates from the pin 211, the pin 211 is located in the larger inner diameter part of the latching hole 1221, that is, the latching portion of the sliding plate 122 separates from the pin 211, and the auxiliary device is disengaged. The latching portion 1222 can also be configured as a V-shaped structure, with the pin 211 of the auxiliary device latched through the bottom of the V-shaped structure. Similarly, the latching hole 1221 can be located on both sides of the sliding plate opposite to the pin holes 1241 on both sides of the sliding bracket 124.

[0063] Figure 5The figure shows a cross-sectional view of the overall structure after the sliding bracket 124, sliding unit 123, and sliding plate 122 are assembled. As can be seen from the figure, when there is no insertion, the pin hole 1241 on the sliding bracket 124 corresponds to the larger inner diameter part of the snap-fit ​​hole 1221 on the sliding plate 122, thereby enabling the smooth insertion of the pin 211 of the auxiliary device. When the pin 211 of the auxiliary device is inserted through the pin hole 1241 on the sliding bracket 124, and the sliding plate 122 moves forward in the second direction under the action of the first elastic member 1232, the sliding plate 122 snaps the pin 211 through the snap-fit ​​part 1222 of the snap-fit ​​hole 1221, that is, the smaller inner diameter part of the snap-fit ​​hole 1221 snaps the pin 211, thereby realizing the connection between the devices. When the device needs to be separated, the sliding seat 1230 can be moved by external force, thereby causing the sliding plate 122 to move in the opposite direction in the second direction. When the locking part 1222 of the locking hole 1221 disengages from the pin 211, the pin 211 can be pulled out of the pin hole 1241.

[0064] In summary, the connecting assembly proposed in this application combines a sliding bracket 124, a sliding unit 123, and a sliding plate 122. A pin hole 1241 is provided on the sliding bracket 124, a first elastic element 1232 is provided within the sliding unit 123, and a snap-fit ​​hole 1221 is provided on the sliding plate 122. When the pin 211 of the auxiliary device is inserted into the pin hole 1241, the first elastic element 1232 drives the sliding unit 123 to slide automatically, and also drives the sliding plate 122 to slide, thereby automatically snapping the snap-fit ​​portion 1222 of the snap-fit ​​hole 1221 of the sliding plate 122 onto the pin 211 without manual intervention, achieving automatic locking. When it is necessary to separate the auxiliary device, simply slide the sliding seat 1230 in another direction. The sliding seat 1230 will then drive the sliding plate 122 to separate the snap-fit ​​portion 1222 from the pin 211, easily achieving the separation of the auxiliary device. The operation is very simple and convenient, improving the efficiency of equipment maintenance.

[0065] To further improve the ease of use of the connection components, such as Figure 2 and Figure 3As shown, in some embodiments of this application, a second sliding hole 1244 is provided on the other side of the sliding bracket 124 opposite to the sliding cavity 1242 in a first direction; a first fixing hole 1236 is provided through the sliding seat 1230 in a first direction opposite to the second sliding hole 1244; a first abutting pin 1231 and a second elastic member 1233 are movably disposed in the first fixing hole 1236, one end of the first abutting pin 1231 extends out of the first fixing hole 1236 and the second sliding hole 1244, and the other end of the first abutting pin 1231 is connected to the second elastic member 1233; the end of the second elastic member 1233 away from the first abutting pin 1231 is fixedly connected to the sliding seat 1230, and the second elastic member 1233 is used to drive the first abutting pin 1231 to slide in the first fixing hole 1236.

[0066] Continue to refer to Figure 2 and Figure 3 A second sliding hole 1244 is provided on the side of the sliding cavity 1242 on the sliding bracket 124 that is away from the first sliding hole 1243, and the second sliding hole 1244 is also connected to the sliding cavity 1242.

[0067] In order to facilitate the fixing of the sliding position of the sliding seat 1230, in this embodiment of the application, a first fixing hole 1236 is provided through the sliding seat 1230 in the first direction. The first fixing hole 1236 is positioned opposite to the first sliding hole 1243 and the second sliding hole 1244, so that the first abutting pin 1231 provided in the first fixing hole 1236 extends out of the second sliding hole 1244.

[0068] The second elastic element 1233 is disposed within the first fixing hole 1236 on the side near the sliding plate 122. The second elastic element 1233 is provided to allow the first abutment pin 1231 to slide freely within the first fixing hole 1236 under the action of elastic force. Therefore, the end of the second elastic element 1233 away from the first abutment pin 1231 is relatively fixed to the sliding seat 1230. This relative fixation can be achieved by fixing the end of the second elastic element 1233 away from the first abutment pin 1231 to the sliding seat 1230, or by fixing the end of the second elastic element 1233 away from the first abutment pin 1231 to the sliding plate 122, but without relative movement between them; they are relatively fixed. Figure 2 As shown, a fifth fixing hole 1223 is provided on the sliding plate 122, and the end of the second elastic member 1233 away from the first abutment pin 1231 is fixedly disposed at the fifth fixing hole 1223.

[0069] The other end of the first abutment pin 1231 extends out of the second sliding hole 1244 of the sliding bracket 124 under the action of the second elastic member 1233. When the first abutment pin 1231 extends out of the second sliding hole 1244, a blocking mechanism can be provided externally to block the first abutment pin 1231, thereby limiting the first abutment pin 1231 and fixing the sliding unit 123 in a specific position. At the same time, since the first abutment pin 1231 can also retract, when the first abutment pin 1231 retracts back into the second sliding hole 1244, the external blocking mechanism cannot block the first abutment pin 1231, and the sliding unit 123 can slide freely in the sliding cavity 1242 under the action of the first elastic member 1232.

[0070] In some embodiments, to better enable the second elastic element 1233 to drive the first abutment pin 1231 to slide freely within the first fixing hole 1236, such as... Figure 5 As shown, a limiting protrusion 12310 is provided on the surface between the two ends of the first abutment pin 1231. This limiting protrusion 12310 can surround the surface of the first abutment pin 1231 or partially surround it. Simultaneously, a limiting platform 12360 is provided on the inner wall of the first fixing hole 1236. The limiting protrusion 12310 and the limiting platform 12360 cooperate to abut against each other, limiting the movement position of the first abutment pin 1231 within the first fixing hole 1236. The other side of the limiting protrusion 12310 abuts against the second elastic member 1233, so that the second elastic member 1233 elastically compresses the first abutment pin 1231.

[0071] like Figure 5 As shown, by setting the limiting protrusion 12310 and the limiting platform 12360, the first abutment pin 1231, under the action of the second elastic member 1233, slides outward to the limiting platform 12360 at its maximum stroke, thereby preventing the first abutment pin 1231 from sliding out of the first fixing hole 1236 under the action of the second elastic member 1233. When pressure is applied to the first abutment pin 1231, the limiting protrusion 12310 of the first abutment pin 1231 squeezes the second elastic member 1233, causing the second elastic member 1233 to be in an elastic deformation state, thereby realizing the retraction of the first abutment pin 1231.

[0072] In some embodiments, to facilitate applying an external force to the sliding unit 123 and moving it, such as... Figure 2 and Figure 3As shown in this embodiment, the sliding bracket 124 is provided with a third sliding hole 1245 on the third-direction upward side; the sliding seat 1230 is provided with a sliding switch 1235 on the third-direction upward side opposite to the third sliding hole 1245, and the sliding switch 1235 extends out of the third sliding hole 1245 to drive the sliding seat 1230 to slide freely in the sliding cavity 1242.

[0073] A third fixing hole 1238 can be provided on the sliding seat 1230. A sliding switch 1235 is fixedly installed in the third fixing hole 1238. The sliding switch 1235 extends out into a third sliding hole 1245. When an external force is applied to the sliding switch 1235, the sliding switch 1235 can drive the sliding seat 1230 to move in a positive or negative direction in the sliding cavity 1242, which greatly facilitates the sliding operation of the sliding seat 1230.

[0074] To improve the integration and durability of the connection component, in this embodiment, the connection component further includes a fixing plate 121, such as... Figure 1 and 2 As shown, the fixed plate 121 and the sliding plate 122 are arranged adjacent to each other, and the sliding plate 122 is movably mounted on one side of the sliding bracket 124. A space is left between the fixed plate 121 and the sliding bracket 124, and the sliding plate 122 slides freely within the space between the fixed plate 121 and the sliding bracket under the action of the sliding unit 123. A specific arrangement is as follows... Figure 2 As shown, the fixed plate 121 is provided with a fourth fixing hole 1210 in a first direction; the sliding plate 122 is provided with a fourth sliding hole 1220 in a first direction opposite to the fourth fixing hole 1210; the sliding bracket is provided with a first connecting post 1240 in a first direction opposite to the fourth sliding hole 1220; the first connecting post 1240 movably passes through the fourth sliding hole 1220 of the sliding plate 122 and is fixedly connected to the fourth fixing hole 1210 of the fixed plate 121.

[0075] A fourth fixing hole 1210 is provided on the fixing plate 121. A first connecting post 1240 on the sliding bracket 124 passes through the fourth sliding hole 1220 on the sliding plate 122 and is connected to the first fixing hole 1236 to fix the fixing plate 121 and the fixing bracket together. The fourth sliding hole 1220 on the sliding plate 122 is a hole-like structure of a certain length, so that when the sliding plate 122 slides, the first connecting post 1240 will not abut against the fourth sliding hole 1220, thus avoiding restriction on the free sliding of the sliding plate 122. Simultaneously, the two ends of the fixing plate 121 are arranged opposite to the pin holes 1241 of the sliding bracket, which can restrict the position of the pin 211 of the auxiliary device and prevent damage to the device. Therefore, by providing the fixing plate 121, this embodiment of the application can effectively prevent external components from affecting the sliding of the sliding plate 122, improving the integration and durability of the connecting components.

[0076] The connection component proposed in this application embodiment can be used together with other devices, such as... Figure 6 The illustration shows a diagnostic system 1000 according to an embodiment of this application. The diagnostic system 1000 includes a diagnostic device 10 and an auxiliary device 20. The diagnostic device 10 can be a host computer such as an industrial platform, and the auxiliary device 20 can be a slave computer such as an air conditioner repair tool. The connecting component can be disposed together with the diagnostic device 10 or with the auxiliary device 20. The diagnostic device 10 and the auxiliary device 20 are relative to each other. In this embodiment, the example of the connecting component being disposed on the diagnostic device 10 is used for illustration.

[0077] like Figure 6As shown, the diagnostic device 10 includes a housing 11, within which a receiving space is formed. The connecting assembly 12 is disposed within the receiving space of the housing 11. The connecting assembly 12 is fixedly connected to the housing 11 via a sliding bracket 124. A first through hole 111 is provided on the housing 11 opposite to the pin hole 1241, through which the pin 211 of the auxiliary device 20 can be inserted. A second through hole 112 is provided on the housing 11 opposite to the second sliding hole 1244, and the diameter of the second through hole 112 in the second direction is smaller than that of the second sliding hole 1244 in the second direction. The first abutment pin 1231 can extend out of the housing 11 through the second through hole 112. A through hole is also provided on the housing 11 opposite to the sliding switch 1235, through which the sliding switch 1235 extends out of the housing 11 for user operation. The purpose of setting the diameter of the second through hole 112 to be smaller than that of the second sliding hole 1244 is that the second through hole 112 needs to restrict the movement of the first abutment pin 1231, while the second sliding hole 1244 needs to provide space for the movement of the first abutment pin 1231.

[0078] During operation, when the auxiliary device's pin 211 is inserted through the first through hole 111, the auxiliary device presses against the first abutment pin 1231, causing the first abutment pin 1231 to retract and exit the second through hole 112. Under the action of the first elastic member 1232, the sliding seat 1230 drives the sliding plate 122 to move forward in the second direction, and the sliding plate 122 engages with the pin 211. When the sliding seat 1230 drives the sliding plate 122 and the first abutment pin 1231 to move in opposite directions in the second direction, the first abutment pin 1231 penetrates the second through hole 112 under the action of the second elastic member 1233. The second through hole 112 limits the first abutment pin 1231, fixing the sliding seat 1230 and the sliding plate 122, so that the sliding plate 122 is disengaged from the pin 211.

[0079] Figure 7 The structure of the auxiliary device 20 is shown in the figure. The auxiliary device 20 includes a device body 210. A pin 211 is provided on the device body 210 at a position opposite to the first through hole 111 of the diagnostic device 10. The pin 211 is used to insert into the first through hole 111. A second abutment pin 222 is provided on the device body 210 at a position opposite to the second through hole 112. The second abutment pin 222 is used to abut against the first abutment pin 1231 so that the first abutment pin 1231 retracts and exits the second through hole 112.

[0080] The pin 211 is used to insert into the first through hole 111 of the diagnostic device 10 to connect with the diagnostic device 10. In addition to its connection function, the pin 211 can also be provided with a male head, and a female head can also be provided in the pin hole 1241 of the diagnostic device 10. When the pin 211 is inserted into the pin hole 1241, the signal between the diagnostic device 10 and the auxiliary device 20 is connected through the male head and the female head, thereby realizing a fixed connection between the two.

[0081] A second abutment pin 222 is also provided on the side of the device body 210 facing the main device, opposite to the second through hole 112. The position of the second abutment pin 222 and the position of the pin 211 correspond to the positions of the first through hole 111 and the second through hole 112 on the diagnostic device 10. When inserted, it can limit the movement to ensure that each part corresponds to the other.

[0082] When the pin 211 is inserted into the first through hole 111, the second abutment pin 222 presses against the first abutment pin 1231, causing the first abutment pin 1231 to retract into the housing 11 of the diagnostic device 10.

[0083] In order to achieve the engagement of the sliding plate 122's engaging portion with the pin 211, in this embodiment of the application, the pin 211 includes a engaging post 2111, and the engaging portion 1222 of the sliding plate 122 cooperates with the engaging post 2111 to engage the pin 211. Figure 4 and Figure 7 As shown, a snap-fit ​​post 2111 is provided at one end of the pin 211. The snap-fit ​​post 2111 has a gourd-like structure, with the inner diameter of the middle part being smaller than the inner diameter of the end part. This allows it to be adapted to the structure of the snap-fit ​​part 1222, so that the snap-fit ​​post 2111 and the snap-fit ​​part 1222 can cooperate to snap the pin 211.

[0084] Figure 8 shows a schematic diagram of the assembly of the diagnostic device 10 and the auxiliary device 20 described above. Figure 8 In the diagram, partial views A1 and A2 show a structural schematic diagram of the auxiliary device 20 when the pin 211 is inserted into the first through hole 111 of the diagnostic device 10.

[0085] refer to Figure 8In partial views A1 and A2, before the pin 211 of the auxiliary device 20 is inserted, in the diagnostic device 10, the first abutment pin 1231 of the connecting assembly extends out of the second through hole 112 on the housing 11 of the diagnostic device 10. The connecting assembly is in an unlocked state, and the inner wall of the second through hole 112 on the housing 11 blocks the first abutment pin 1231, keeping the sliding unit 123 stationary. The first elastic element 1232 of the sliding unit 123 is in an elastically deformed state. The pin hole 1241 of the sliding bracket 124 corresponds to the larger inner diameter portion of the snap-fit ​​hole 1221 of the sliding plate 122, and is in an unobstructed state.

[0086] When the auxiliary device 20 is inserted, refer to Figure 8 In partial view A1, when the pin 211 passes through the first through hole 111 into the pin hole 1241 of the sliding bracket 124, the locking post 2111 of the pin 211 is located within the locking hole 1221 of the sliding plate 122. Simultaneously, the second abutment pin 222 of the auxiliary device 20 is positioned opposite to the first abutment pin 1231 of the diagnostic device 10, thereby pressing the first abutment pin 1231. The second elastic element 1233 is in an elastic deformation state, causing the first abutment pin 1231 to retract inward, thus disengaging from the obstruction of the inner wall of the second through hole 112 on the outer shell of the diagnostic device 10. Under the action of the first elastic element 1232, the sliding seat 1230 slides in the first direction, thereby causing the sliding plate 122 and the first abutment pin 1231 to also slide. (Reference) Figure 8 In partial view A2, when the sliding plate 122 slides, the engaging portion 1222 of the engaging hole 1221 on the sliding plate 122 abuts against the engaging post 2111 of the pin 211, thereby engaging the engaging portion 1222 against the engaging post 2111. By setting components such as the abutment pin, elastic element, and sliding plate, the automatic connection between the auxiliary device 20 and the diagnostic device 10 is achieved without manual intervention. Moreover, the engaging portion 1222 securely engages the engaging post 2111, making the connection between the diagnostic device 10 and the auxiliary device 20 very stable.

[0087] When it is necessary to separate the diagnostic device 10 and the auxiliary device 20, the process is reversed. First refer to... Figure 8Partial view A2. During separation, the sliding switch 1235 is first manually slid to move it in the opposite direction in the first direction. The sliding switch 1235 drives the sliding seat 1230 to move, thereby driving the sliding plate 122 and the first abutment pin 1231 to move. The first elastic element 1232 is in an elastic deformation state. When the first abutment pin 1231 moves to the second through hole 112 on the housing 11, the first abutment pin 1231 and the second abutment pin 222 abut against each other. At this time, the locking part 1222 of the locking hole 1221 of the sliding plate 122 is separated from the locking post 2111 of the pin 211. At this time, the auxiliary device 20 and the diagnostic device 10 can be freely separated. When the pin 211 of the auxiliary device 20 disengages from the first through hole 111, the second abutment pin 222 will also separate from the first abutment pin 1231. When the second elastic element 1233 is in an elastic deformation state, when the second abutment pin 222 separates from the first abutment pin 1231, the first abutment pin 1231 pops out of the second through hole 112 under the action of the second elastic element 1233. The inner wall of the second through hole 112 limits the first abutment pin 1231, so that the sliding seat 1230 and the sliding plate 122 are in a fixed state, while the pin hole 1241 and the snap hole 1221 of the sliding plate 122 are in an unobstructed state, thereby restoring the diagnostic device 10 to a pluggable state. Figure 9 The diagram illustrates the resulting diagnostic system after connecting the diagnostic and auxiliary devices, showcasing a compact structure. Signal transmission between the diagnostic and auxiliary devices can be achieved via Bluetooth, WiFi, or the aforementioned male and female connectors; no specific method is specified here.

[0088] In summary, the diagnostic device, auxiliary device, and diagnostic system formed by the interconnection of the diagnostic device and auxiliary device provided in this application embodiment can easily realize the connection and separation between the diagnostic device and the auxiliary device through the connecting component. When locked, no intervention is required, and automatic autonomous locking can be achieved. The structure is stable. When separation is required, the two can be separated simply by moving the sliding switch. This makes the cooperation between different devices very convenient and improves the efficiency of equipment maintenance.
