[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] Reference below Figure 1-Figure 4 The OBD diagnostic interface bracket 100 according to the first embodiment of the utility model is described.

[0040] First of all, it is worth explaining that OBD (On-Board-Diagnostic) is an on-board diagnostic system (hereinafter referred to as OBD), which is used to monitor the working status of the engine and other working modules in real time during the operation of the car. Once an abnormality is found, it will be recorded in the memory in the form of a fault code. When maintaining and repairing the vehicle, maintenance personnel can quickly and accurately locate the relevant parts through the fault code for subsequent maintenance. It is worth explaining that an external fault diagnosis computer is usually used to obtain the fault code, and the connector of the external fault diagnosis computer is connected to the diagnostic interface 200 of the OBD on the vehicle so that the external fault diagnosis computer can read and display the fault code. Therefore, when using OBD for vehicle diagnosis, in order to facilitate maintenance personnel to plug in the diagnostic interface 200 of the OBD, the diagnostic interface 200 needs to be fixed in the vehicle through the OBD diagnostic interface bracket 100.

[0041] like Figure 1 As shown, an OBD diagnostic interface bracket 100 according to some embodiments of the first aspect of the utility model.

[0042] The OBD diagnostic interface bracket 100 includes an assembly position 3, which is used to assemble the OBD diagnostic interface 200. The diagnostic interface 200 is installed at the assembly position 3 and the pins in the diagnostic interface 200 are completely exposed, so that maintenance personnel can observe the position of the diagnostic interface 200 and perform operations such as plugging it.

[0043] Optionally, the opening size of the assembly position 3 is adapted to the size of the diagnostic interface 200 , and during installation, the staff can quickly and accurately place the diagnostic interface 200 into the assembly position 3 .

[0044] Optionally, the opening size of the assembly position 3 can be slightly larger than the size of the diagnostic interface 200. Taking into account the installation environment of the staff, sometimes the OBD is installed at the bottom left of the dashboard, and the operable position is small. The slightly larger size of the assembly position 3 can allow the staff to easily place the diagnostic interface 200 into the assembly position 3 during installation.

[0045] In some embodiments, the OBD diagnostic interface bracket 100 further includes a guide structure disposed around the assembly position 3 to guide the staff to accurately place the diagnostic interface 200. The guide structure may adopt a known solution in the prior art, and since the guide structure itself is not the core point of the present application solution, it will not be described here.

[0046] The OBD diagnostic interface bracket 100 is provided with a plug hole 4. Since the plug hole does not need to be fixed with additional fasteners, the staff can insert the plug plate 21 on one side of the diagnostic interface 200 into the plug hole 4, so that the diagnostic interface 200 and the assembly position 3 are pre-positioned before fixation, so as to ensure that the diagnostic interface 200 and the OBD diagnostic interface bracket 100 remain stable and avoid shaking or deviation, which is conducive to subsequent fixed connection.

[0047] In some embodiments, buckles, springs, etc. are further provided around the plug hole 4. When the diagnostic interface 200 is inserted into the plug hole 4, buckles, springs, etc. can be used to fix it and the OBD diagnostic interface bracket 100 to keep it locked and engaged.

[0048] Optionally, the plug hole 4 is a long hole. This arrangement allows the diagnostic interface 200 to have a certain amount of room for movement when inserted, and can accommodate insertion at different positions and angles. At the same time, the long hole can also serve as a guide, guiding the staff to accurately insert the plug board 21 of the diagnostic interface 200 into the plug hole 4.

[0049] In addition, the long hole can also facilitate the staff to align and adjust the position of the diagnostic interface 200 during the installation process. If the diagnostic interface 200 is found to be incorrectly positioned or has a certain deviation after being inserted into the plug hole 4, the user can adjust it by moving the diagnostic interface 200 in the long hole so that it is correctly aligned with the OBD diagnostic interface bracket 100 and remains stable, which is convenient for the staff to install and operate.

[0050] like Figure 1-Figure 4 As shown, the OBD diagnostic interface bracket 100 includes a mounting plate 6 , on which a mounting hole 60 is provided. The mounting hole 60 provides a fixing position for the connecting plate 22 of the diagnostic interface 200 so that the diagnostic interface 200 is fixed on the OBD diagnostic interface bracket 100 .

[0051] It can be seen that before the diagnostic interface 200 is installed, the plug plate 21 is first pre-assembled with the plug hole 4, and after the pre-assembly is completed, the connection plate 22 is connected with the mounting plate 6 to achieve a firm fixation. Through pre-assembly and fixed connection, the diagnostic interface 200 can be installed quickly and accurately, simplifying the installation steps and improving work efficiency.

[0052] Optionally, the shape and size of the mounting plate 6 can also be customized according to the size and shape of the connecting plate 22 of the diagnostic interface 200 to ensure the compatibility between the two. At the same time, the stability between the connecting plate 22 and the mounting plate 6 can be increased to reduce the possibility of shaking or loosening during use.

[0053] Alternatively, the size of the mounting plate 6 is slightly larger than the size of the connecting plate 22 of the diagnostic interface 200, which can provide the diagnostic interface 200 with a larger moving space, and facilitate the disassembly of the plug-in plate 21 and the plug-in hole 4 after the connecting plate 22 and the mounting hole 60 are released. It is worth noting that when the connector of the external fault diagnosis computer is plugged into the diagnostic interface 200, the OBD diagnostic interface bracket 100 is subjected to external pressing force, so the larger mounting plate 6 can also provide additional support and stability to ensure the reliability of the diagnostic interface 200 during use.

[0054] In some embodiments, reinforcing ribs may be provided inside the mounting plate 6, and the reinforcing ribs are located away from the mounting holes 60. Alternatively, the thickness of the mounting plate 6 is increased to improve its load-bearing capacity and ability to resist external interference. Alternatively, the mounting plate 6 is made of a high-strength, high-rigidity material, such as high-strength plastic, to increase its ability to resist external forces.

[0055] like Figure 1 As shown, the plug hole 4 and the mounting plate 6 are located on opposite sides of the assembly position 3, forming a symmetrical structure. It can be seen that the plug hole 4 and the mounting plate 6 form certain constraints on the diagnostic interface 200 at symmetrical positions, preventing the diagnostic interface 200 from moving or tilting, and keeping it in the correct position. In addition, the force on the OBD diagnostic interface bracket 100 can also be balanced to avoid stress concentration and deformation during the process of plugging and unplugging the connector.

[0056] like Figure 2-Figure 4 As shown, according to some embodiments of the OBD diagnostic interface bracket 100 of the present invention, the two opposite sides of the OBD diagnostic interface bracket 100 in the thickness direction are the inner side and the outer side, and the wire 23 of the diagnostic interface 200 is located on the inner side. This is because, during daily driving, the wire 23 of the diagnostic interface 200 is hidden inside the OBD diagnostic interface bracket 100, which can ensure the consistency of the appearance and prevent the wire from being worn or interfered.

[0057] like Figure 3As shown, the OBD diagnostic interface bracket 100 includes a protrusion 5, which is protruding outward relative to the assembly position 3, and the plug-in hole 4 is located on the side of the protrusion 5 facing the assembly position 3, that is, the plug-in hole 4 is installed at the chamfered position of the protrusion 5. Since the strength of the chamfered position is relatively large, it can play a better supporting role. In addition, the chamfered position can also provide better lateral support when the plug-in hole 4 is subjected to external force generated by the plug / unplug of the connector, thereby improving its anti-bending and anti-twisting capabilities. At the same time, when the diagnostic interface 200 is assembled to the assembly position 3, the plug-in board 21 on one side of the diagnostic interface 200 can be inserted into the plug-in hole 4 horizontally and directly, which is not only easy to operate, but also does not require the plug-in board 21 to be deformed.

[0058] In some embodiments, the protrusion 5 is extended along the height direction of the OBD diagnostic interface bracket 100 to increase the overall strength of the OBD diagnostic interface bracket 100 .

[0059] like Figure 3-Figure 4 As shown, according to some embodiments of the OBD diagnostic interface bracket 100 of the utility model, the protrusion 5 is formed by a part of the OBD diagnostic interface bracket 100 protruding outward and deforming, and the protrusion 5 forms a first receiving groove 51 toward the inside, and the plug hole 4 is connected to the first receiving groove 51. By setting the hollow first receiving groove 51, the protrusion 5 does not need to be additionally thickened relative to the entire bracket, thereby reducing the material cost. Obviously, the hollow first receiving groove 51 can also accommodate the plug plate 21. Specifically, the plug plate 21 is hidden in the first receiving groove 51 to maintain the consistency of the vehicle as a whole.

[0060] like Figure 3 As shown, according to some embodiments of the OBD diagnostic interface bracket 100 of the present invention, the inner surface of the plug hole 4 near the inner side is the first abutting surface 52. After the plug board 21 of the diagnostic interface 200 is inserted into the plug hole 4 and enters the first receiving groove 51, it abuts against the first abutting surface 52.

[0061] like Figure 2-Figure 3 As shown, the surface of the mounting plate 6 facing outward is the second abutting surface 62. The second abutting surface 62 abuts against the connecting plate 22 from inside to outside, which is equivalent to the other side of the diagnostic interface 200 being subjected to pressure from inside to outside.

[0062] When the connector of the external fault diagnosis computer is inserted, pressure is exerted inward on the plug-in board 21 and the mounting plate 6 on the diagnostic interface 200. The first abutting surface 52 abuts against the plug-in board 21, and the second abutting surface 62 abuts against the connecting plate 22. The two abutting surfaces are equivalent to strengthening the supporting strength of the plug-in board 21 and the connecting plate 22, thereby avoiding deformation of the diagnostic interface 200.

[0063] Obviously, with such an arrangement, the diagnostic interface 200 can be subjected to pressure on both the inner and outer sides thereof, thereby effectively preventing the plug board 21 from shaking back and forth, thereby improving the stability and reliability of the diagnostic interface 200 .

[0064] The first abutting surface 52 and the second abutting surface 62 are arranged flush with each other. Figure 3 As shown, and located on opposite sides of the diagnostic interface 200, the external forces in two directions applied to the diagnostic interface 200 by the first abutting surface 52 and the second abutting surface 62 are at the same horizontal position, which can provide a more balanced support force for the diagnostic interface 200 and avoid problems such as distortion or deformation caused by uneven pressure due to unstable positions on both sides. At the same time, the flush setting of the first abutting surface 52 and the second abutting surface 62 can also facilitate the connection and disassembly of the staff, especially when plugging in, the two sides of the diagnostic interface 200 do not interfere with each other. Not only that, it can also facilitate the processing and positioning of the diagnostic interface 200 and the plug board 21 and the connecting plate 22.

[0065] like Figure 2-Figure 4 As shown, according to some embodiments of the OBD diagnostic interface bracket 100 of the present invention, the two opposite sides of the OBD diagnostic interface bracket 100 in the thickness direction are the inner side and the outer side, and the wire 23 of the diagnostic interface 200 is located on the inner side. By hiding the wire 23 of the diagnostic interface 200 inside the OBD diagnostic interface bracket 100, the consistency of the vehicle appearance can be ensured on the one hand, and the safety of the wire 23 can be ensured on the other hand, and the wear of the wire 23 can be avoided.

[0066] A portion of the mounting plate 6 is deformed and convex toward the outside, such as Figure 3-Figure 4 As shown, the mounting plate 6 forms a second receiving groove 61 toward the inside, and the mounting hole 60 is connected to the second receiving groove 61. It is worth noting that when the diagnostic interface 200 is installed in the assembly position 3, the connecting plate 22 and the mounting plate 6 are overlapped and fixed by the connecting member 8 and the screw clamp 7. Since the second receiving groove 61 forms a hollow structure, the screw clamp 7 is arranged in the second receiving groove 61 to position the connecting member 8, which can save the space occupied by the screw clamp 7 in the vehicle and facilitate the layout of other structures inside the vehicle. In addition, the screw clamp 7 is hidden inside the OBD diagnostic interface bracket 100 to ensure the consistency of the appearance as a whole.

[0067] Optionally, the connecting member 8 can be replaced by a detachable workpiece such as a bolt, a latch, etc. The screw clamp 7 can be replaced by a nut, etc. to match the connecting member 8.

[0068] like Figure 1-Figure 2As shown, according to some embodiments of the present invention, the OBD diagnostic interface bracket 100 includes a mainboard 10, and the mainboard 10 is provided with an assembly port 31 that passes through the mainboard 10. The size and shape of the assembly port 31 match the diagnostic interface 200 to form an assembly position 3 for installing the diagnostic interface 200. It is convenient for the staff to accurately install the diagnostic interface 200 on the mainboard 10 through the assembly port 31, and the pins on the diagnostic interface 200 are completely exposed for easy plugging.

[0069] In some embodiments, the mainboard 10 is an integrally formed part, and no extra waste is generated during the forming process, which can reduce environmental pollution such as waste gas and waste water during production, improve production efficiency, and be environmentally friendly and energy-saving. The production method of the integrally formed part can also reduce errors in human operation, improve the accuracy and consistency of the mainboard 10, and ensure its quality.

[0070] In some embodiments, Figure 1-Figure 4 As shown, the main board 10 further includes a first support plate 11. It is worth noting that the two opposite sides of the OBD diagnostic interface bracket 100 in the length direction are the left side and the right side, and the first support plate 11 is located on the left side of the main board 10, and the OBD diagnostic interface bracket 100 is connected to the vehicle through the first support plate 11.

[0071] Optionally, the first support plate 11 includes a first vertical section 112, a first horizontal section 113, and a second vertical section 114. Part of one end of the first vertical section 112 is connected to the mounting plate 6, and an angle is formed between the first vertical section 112 and the mounting plate 6. The angle may be 85°-135°, for example, 85°, 90°, 95°, 110°, 135°. Preferably, the angle is 90°.

[0072] The first horizontal section 113 is connected to the other end of the first vertical section 112 , and the first horizontal section 113 is arranged parallel to the mounting plate 6 .

[0073] An angle is formed between the second vertical section 114 and the first horizontal section 113. The angle may be 85°-135°, for example, 85°, 90°, 95°, 110°, 135°. Preferably, the angle is 90°.

[0074] The second vertical section 114 and the first vertical section 112 connect the two ends of the first horizontal section 113. The first support plate 11 can not only form a support force for the OBD diagnostic interface bracket 100, but also shield a part of the internal structure of the vehicle, so that the OBD diagnostic bracket is more complete as a whole and has a sense of continuity with the connection part of the vehicle.

[0075] In some embodiments, Figure 1 , Figure 2 , Figure 4As shown, the main board 10 further includes a first connecting plate 15. It is worth noting that the two opposite sides of the OBD diagnostic interface bracket 100 in the height direction are the upper side and the lower side, and the first connecting plate 15 is arranged at the lower side of the first horizontal section 113, and the left and right sides of the first connecting plate 15 are respectively connected to the first vertical section 112 and the second vertical section 114, which can enhance the structural stability of the first support plate 11.

[0076] In some embodiments, Figure 1-Figure 4 As shown, the main board 10 further includes a first bending section 14 disposed on the right side of the main board 10. Specifically, the first bending section 14 is located on the side of the protrusion 5 away from the assembly position 3, and the folded plane of the first bending section 14 is arranged parallel to the first abutting surface 52 of the protrusion 5.

[0077] In some embodiments, Figure 1 , Figure 2 , Figure 4 As shown, the main board 10 further includes a second connecting plate 16 and a third connecting plate 17. The second connecting plate 16 is disposed on the upper side of the OBD diagnostic interface bracket 100 and is connected to the first bending section 14 and the protrusion 5; the third connecting plate 17 is disposed on the lower side of the OBD diagnostic interface bracket 100 and is connected to the first bending section 14 and the protrusion 5. This arrangement can provide stable support for the upper and lower sides of the OBD diagnostic interface bracket 100, so that deformation is not easy to occur between the first bending section 14 and the protrusion 5.

[0078] In some embodiments, Figure 1 , Figure 2 , Figure 4 As shown, the main board 10 further includes a second support plate 12 and a third support plate 13 connected to the mounting plate 6 and the protrusion 5. The second support plate 12 and the third support plate 13 are respectively located at the upper side and the lower side of the assembly position 3, and they are used to support and position the main board 10. It can prevent the main board 10 from bending or deforming during use. It can be seen that the mounting plate 6, the protrusion 5, the second support plate 12, and the third support plate 13 are surrounded to form an assembly opening 31.

[0079] Optionally, the second support plate 12 and the third support plate 13 may be integrated with the main board 10 to facilitate the production of the main board 10. Alternatively, they may be fixed by welding or other means to increase the connection strength between them and the main board 10.

[0080] A connection structure of an on-board diagnostic system according to an embodiment of the second aspect of the utility model.

[0081] like Figure 2-Figure 4 As shown, the above connection structure includes an OBD diagnostic interface bracket 100 and a diagnostic interface 200. The OBD diagnostic interface bracket 100 adopts the OBD diagnostic interface bracket 100 in the first embodiment of the present application.

[0082] The diagnostic interface 200 comprises an interface body 20, a plug board 21, a connecting board 22 and a wire 23. The diagnostic interface 200 is used to connect to a connector of an external fault diagnosis computer.

[0083] like Figure 3 As shown, the plug plate 21 and the connecting plate 22 are connected to opposite sides of the interface body 20, so that one side of the interface body 20 is plugged into the plug hole 4 through the plug plate 21 to achieve pre-assembly. The connecting plate 22 on the other side is overlapped with the mounting plate 6, and the connecting plate 22 is matched with the mounting hole 60 on the mounting plate 6 through the connecting piece 8, so as to achieve the fixation of the diagnostic interface 200.

[0084] like Figure 2-Figure 4 As shown, one end of the wire 23 is connected to the interface body 20 to transmit an electrical signal to an external fault diagnosis computer through the diagnostic interface 200. It is known that when the diagnostic interface 200 is installed in the OBD diagnostic interface bracket 100, the wire 23 faces the inner side of the OBD diagnostic interface bracket 100, and the diagnostic interface 200 is exposed to the assembly position 3 of the OBD diagnostic interface bracket 100 and faces the user, which is convenient for the user to use.

[0085] like Figure 2-Figure 3 As shown, according to the connection structure of the on-board diagnostic system of some embodiments of the present invention, a connection hole 221 is provided on the connection plate 22, and the connection member 8 passes through the connection hole 221 and the mounting hole 60 in sequence. The connection member 8 and the connection hole 221 can be matched by interference fit, clearance fit or other suitable matching methods to achieve the best fixing effect.

[0086] The connecting member 8 and the connecting hole 221 are separate parts. For example, the connecting member 8 is a screw, a bolt, a latch, etc.

[0087] Optionally, a connecting member 8 is fixedly connected to the connecting plate 22, and the connecting member 8 passes through the mounting hole 60. For example, the connecting member 8 may be integrally formed on the connecting plate 22 and inserted into the mounting hole 60.
