Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of vehicle mounting equipment, and in particular, to a positioning pin assembly and a vehicle mounting equipment. Background Art

[0002] Vehicle-mounted equipment refers to various devices and systems installed on vehicles to improve vehicle performance, safety, comfort, convenience and meet specific functional requirements.

[0003] In the prior art, some important components need to be initially positioned using positioning pins during the installation process. For example, when installing the steering support structure on the vehicle body, positioning pins are required for positioning. Figures 1 to 3 As shown, the steering support structure includes a mounting frame 1', a transverse tube 2' and a locating pin 3'. The mounting frame 1' is provided with a turning hole 101', a pin hole 102' and a mounting hole 103'. The transverse tube 2' is mounted on the mounting frame 1' through the turning hole 101', and then the locating pin 3' is inserted into the pin hole 102' of the mounting frame 1' and then inserted into the locating hole of the vehicle body. Subsequently, the locating pin 3' is pushed a certain distance in the axial direction of the locating hole until the steering support structure contacts the mounting surface of the vehicle body, and finally a fastener is used to be installed in the mounting hole 103' to fix the steering support structure. Due to the above-mentioned assembly characteristics, the locating pin 3' itself is relatively long and heavy, which affects the layout space around the locating pin 3'. Utility Model Content

[0004] In view of this, an embodiment of the present application provides a locating pin assembly and a vehicle installation device, which can shorten the overall length of the locating pin assembly and reduce the weight of the locating pin assembly, provide sufficient installation space for the installation of other components, and at the same time, the disassembled second locating pin can be recycled to save costs.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the embodiment of the present application is implemented as follows:

[0006] In a first aspect, an embodiment of the present application provides a positioning pin assembly, comprising:

[0007] A first positioning pin is provided with an axial through hole, wherein the first positioning pin has an insertion end inserted into the pin hole of the mounting frame and a connection end abutting against the pin hole;

[0008] A second positioning pin, detachably connected to the first positioning pin, having a positioning end and a matching end;

[0009] The first locating pin and the second locating pin have a mating state and a disassembly state. In the mating state, the locating end of the second locating pin is inserted into the axial through hole and extends out of the insertion end, and the mating end abuts against the connecting end. In the disassembly state, the second locating pin is disengaged from the axial through hole of the first locating pin.

[0010] The positioning pin assembly provided in the embodiment of the present application, when using the positioning pin assembly to position the mounting frame, insert the insertion end of the first positioning pin into the pin hole of the mounting frame, and abut the connecting end of the first positioning pin at the pin hole, so that the first positioning pin is installed on the pin hole. Then the positioning end of the second positioning pin is inserted into the axial through hole from the connecting end of the first positioning pin, and when the first positioning pin and the second positioning pin are matched, the positioning end of the second positioning pin extends out of the axial through hole from the insertion end of the first positioning pin, and can deeply enter the positioning hole of the target component, thereby ensuring the positioning stability and assembly accuracy of the positioning pin assembly, and the matching end abuts at the connecting end, so that there is a certain friction between the matching end and the connecting end, thereby enhancing the connection stability of the first positioning pin and the second positioning pin. After the mounting frame is assembled, since the first locating pin and the second locating pin are detachably connected, the cooperation between the first locating pin and the second locating pin can be cancelled, and the second locating pin can be removed from the first locating pin to make the second locating pin disengage from the axial through hole of the first locating pin. This can shorten the overall length of the locating pin assembly and reduce the weight of the locating pin assembly, providing sufficient installation space for the installation of other components. At the same time, the disassembled second locating pin can also be recycled to save costs.

[0011] Compared with the existing positioning pins, when installing the mounting frame, the first positioning pin can be matched with the second positioning pin, so that the positioning pin assembly as a whole has enough length to match the positioning hole of the target component. After the mounting frame is installed, the second positioning pin can be removed from the first positioning pin, thereby shortening the length of the positioning pin assembly and reducing the weight of the positioning pin assembly.

[0012] In a possible implementation of the present application, a first inclined surface is provided on the outer surface of the first positioning pin close to the insertion end, and a diameter of the first positioning pin located at the first inclined surface gradually increases from the insertion end to the connection end.

[0013] In a possible implementation of the present application, a limiting portion is provided on the first positioning pin near the connecting end, and the limiting portion protrudes from an outer surface of the first positioning pin.

[0014] In a possible implementation of the present application, a stepped groove is provided in a middle area of ​​the outer surface of the first positioning pin, and a stepped surface of the stepped groove faces the connecting end.

[0015] In a possible implementation of the present application, a second inclined surface is provided on the outer surface of the first positioning pin between the step groove and the connecting end, one end of the second inclined surface extends to the step groove, and the diameter of the first positioning pin at the second inclined surface gradually increases in the direction from the step groove to the connecting end.

[0016] In a possible implementation of the present application, the first locating pin and the second locating pin are threadedly connected, the inner wall of the axial through hole is provided with an internal thread, and the outer surface of the second locating pin is provided with an external thread that matches the internal thread.

[0017] In a possible implementation of the present application, in the mating state, the length of the locating end of the second locating pin extending out of the insertion end is 20 mm-100 mm.

[0018] In a possible implementation of the present application, the area of ​​the circumferential cross section of the mating end of the second locating pin is larger than the area of ​​the circumferential cross section of other regions of the second locating pin.

[0019] In a possible implementation of the present application, in the mating state, the mating end protrudes from the limiting portion.

[0020] In a second aspect, an embodiment of the present application provides a vehicle installation device, including:

[0021] A mounting frame having a pin hole;

[0022] Positioning pin assembly, the connecting end of the first positioning pin is installed at the pin hole.

[0023] The vehicle mounting device provided by the embodiment of the present application inserts the insertion end of the first locating pin into the pin hole of the mounting frame, and the positioning end of the second locating pin extends from the insertion end of the first locating pin through the axial through hole, and can deeply enter the positioning hole of the target component, thereby ensuring the positioning stability and assembly accuracy of the locating pin assembly. After the mounting frame is assembled, since the first locating pin and the second locating pin are detachably connected, the cooperation between the first locating pin and the second locating pin can be cancelled, and the second locating pin can be removed from the first locating pin, which can shorten the overall length of the locating pin assembly and reduce the weight of the locating pin assembly, providing sufficient installation space for the installation of other components, and the removed second locating pin can also be recycled, saving costs.

[0044] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0045] The present application embodiment provides a positioning pin assembly, such as Figures 4 to 10 As shown, it includes a first positioning pin 1 and a second positioning pin 3.

[0046] Specifically, combined Figures 4 to 8 As shown, an axial through hole 101 is formed on the first positioning pin 1. The first positioning pin 1 has an insertion end 102 and a connection end 103. The insertion end 102 is suitable for inserting into the pin hole 201 of the mounting frame 2, and the connection end 103 abuts against the pin hole 201.

[0047] Specifically, combined Figures 4 to 10 As shown, the second positioning pin 3 is detachably connected to the first positioning pin 1 , and the second positioning pin 3 has a positioning end 301 and a matching end 303 .

[0048] Specifically, combined Figures 5 to 9 As shown, the first positioning pin 1 and the second positioning pin 3 have a mating state and a disassembly state. In the mating state, the positioning end 301 of the second positioning pin 3 is inserted into the axial through hole 101 and extends out of the insertion end 102, and the mating end 303 abuts against the connection end 103. In the disassembly state, the second positioning pin 3 is disengaged from the axial through hole 101 of the first positioning pin 1.

[0049] The positioning pin assembly provided in the embodiment of the present application, when using the positioning pin assembly to position the mounting frame 2, insert the insertion end 102 of the first positioning pin 1 into the pin hole 201 of the mounting frame 2, and abut the connection end 103 of the first positioning pin 1 at the pin hole 201, so that the first positioning pin 1 is installed on the pin hole 201. Then, the positioning end 301 of the second positioning pin 3 is inserted into the axial through hole 101 from the connection end 103 of the first positioning pin 1. When the first positioning pin 1 and the second positioning pin 3 are matched, the positioning end 301 of the second positioning pin 3 extends out of the axial through hole 101 from the insertion end 102 of the first positioning pin 1, and can deeply enter the positioning hole of the target component, thereby ensuring the positioning stability and assembly accuracy of the positioning pin assembly, and the matching end 303 abuts at the connection end 103, so that there is a certain friction between the matching end 303 and the connection end 103, thereby enhancing the connection stability of the first positioning pin 1 and the second positioning pin 3. After the mounting frame 2 is assembled, since the first locating pin 1 and the second locating pin 3 are detachably connected, the cooperation between the first locating pin 1 and the second locating pin 3 can be cancelled, and the second locating pin 3 can be removed from the first locating pin 1, so that the second locating pin 3 can be disengaged from the axial through hole 101 of the first locating pin 1. This can shorten the overall length of the locating pin assembly and reduce the weight of the locating pin assembly, providing sufficient installation space for the installation of other components. At the same time, the disassembled second locating pin 3 can also be recycled to save costs.

[0050] Compared with the existing positioning pins, when installing the mounting frame 2, the first positioning pin 1 can be matched with the second positioning pin 3, so that the positioning pin assembly as a whole has sufficient length to match the positioning hole of the target component. After the mounting frame 2 is installed, the second positioning pin 3 can be removed from the first positioning pin 1, thereby shortening the length of the positioning pin assembly and reducing the weight of the positioning pin assembly.

[0051] Specifically, the cross-section of the first locating pin 1 can be set to any existing shape such as square, circle, etc. Similarly, the cross-section of the second locating pin 3 can also be set to any existing shape such as square, circle or triangle. In the embodiment of the present application, there is no specific restriction on the shapes of the first locating pin 1 and the second locating pin 3.

[0052] Specifically, the axial through hole 101 can be a circular hole or a hole of any existing shape such as a square hole, as long as the second positioning pin 3 can pass through the axial through hole 101. In the embodiment of the present application, the shape of the axial through hole 101 is not specifically limited.

[0053] Exemplarily, the axial through hole 101 can be set to be a circular hole, the cross-section of the second positioning pin 3 is also set to be circular, and the diameter of the cross-section of the second positioning pin 3 is adapted to the diameter of the circular hole, to ensure that after the second positioning pin 3 passes through the axial through hole 101, the second positioning pin 3 and the axial through hole 101 are firmly matched, avoiding the second positioning pin 3 from shaking in the axial through hole 101, resulting in the inability to accurately position the positioning pin assembly.

[0054] Specifically, the first positioning pin 1 and the second positioning pin 3 can adopt an existing detachable connection method. For example, the first positioning pin 1 and the second positioning pin 3 can be connected by a snap-fit ​​connection method, or by a threaded connection method, etc. In the embodiment of the present application, no specific restriction is imposed on the detachable connection method between the first positioning pin 1 and the second positioning pin 3.

[0055] Specifically, when the first positioning pin 1 and the second positioning pin 3 are matched, the positioning end 301 of the second positioning pin 3 extends out of the axial through hole 101. In the embodiment of the present application, there is no specific restriction on the length of the second positioning pin 3 extending out of the axial through hole 101, and it can be set according to actual needs. Similarly, there is no specific restriction on the length of the first positioning pin 1 and the second positioning pin 3, and the length of the second positioning pin 3 can be greater than the length of the first positioning pin 1, or less than the length of the first positioning pin 1.

[0056] In some embodiments of the present application, Figure 7 and Figure 8 As shown, the outer surface of the first positioning pin 1 close to the insertion end 102 is provided with a first inclined surface 104 , and the diameter of the first positioning pin 1 at the first inclined surface 104 gradually increases from the insertion end 102 to the connection end 103 .

[0057] When the insertion end 102 of the first positioning pin 1 is inserted into the pin hole 201, the diameter at the first inclined surface 104 gradually increases from the insertion end 102 to the connection end 103, providing a natural guide for the insertion of the insertion end 102 into the pin hole 201. When the first positioning pin 1 is inserted into the pin hole 201, this gradual diameter can guide the first positioning pin 1 to align smoothly and slide into the pin hole 201, reducing the resistance during the insertion process. And as the diameter gradually increases, after the first positioning pin 1 is fully inserted, a tighter fit can be formed, achieving a certain degree of self-locking fastening effect.

[0058] Specifically, a rounded corner may be provided at the insertion end 102 of the first positioning pin 1 , which may also provide a guiding function so as to facilitate the insertion of the insertion end 102 into the pin hole 201 .

[0059] In some embodiments of the present application, Figure 7 and Figure 8 As shown, the first positioning pin 1 is provided with a limiting portion 105 near the connecting end 103 , and the limiting portion 105 protrudes from the outer surface of the first positioning pin 1 .

[0060] A limiting portion 105 is provided at the connection end 103 of the first locating pin 1. The limiting portion 105 plays a role of precise limiting during the assembly process. When the first locating pin 1 is inserted into the pin hole 201 to a specified position, the limiting portion 105 will contact the corresponding structure or hole edge of the mounting frame 2, providing a clear stop signal to ensure that the first locating pin 1 is installed on the pin hole 201 without being inserted too deeply, thereby avoiding damage to components or inaccurate positioning.

[0061] Specifically, the limiting portion 105 can be provided with any existing limiting structure such as an annular boss structure, a conical limiting structure, etc. In the embodiment of the present application, no specific limitation is imposed on the structure of the limiting portion 105.

[0062] Exemplarily, the first positioning pin 1 is provided in a cylindrical shape, and the limiting portion 105 is provided in an annular boss structure. For example, the diameter of the first positioning pin 1 near the connecting end 103 is 10 mm, and the diameter of the annular boss structure is 15 mm.

[0063] In some embodiments of the present application, Figure 7 and Figure 8 As shown, a stepped groove 106 is formed in the middle area of ​​the outer surface of the first positioning pin 1 , and the stepped surface of the stepped groove 106 faces the connecting end 103 .

[0064] By opening a step groove 106 in the middle area of ​​the outer surface of the first locating pin 1 and making the step surface of the step groove 106 face the connection end 103, the step surface of the step groove 106 can cooperate with the hole wall of the pin hole 201, thereby preventing the first locating pin 1 from falling off from the pin hole 201 due to external vibration or gravity.

[0065] Specifically, the stepped groove 106 is arranged in the middle area of ​​the first positioning pin 1. The stepped groove 106 can be arranged on the outer surface of the first positioning pin 1 close to the insertion end 102, or close to the connection end 103. In the embodiment of the present application, the position of the stepped groove 106 is not specifically restricted.

[0066] In some embodiments of the present application, Figure 7 and Figure 8As shown, a second inclined surface 107 is provided on the outer surface of the first locating pin 1 between the stepped groove 106 and the connecting end 103, and one end of the second inclined surface 107 extends to the stepped groove 106. From the stepped groove 106 to the connecting end 103, the diameter of the first locating pin 1 at the second inclined surface 107 gradually increases.

[0067] When the first positioning pin 1 is inserted into the pin hole 201, after the stepped groove 106 passes through the pin hole 201, since the first positioning pin 1 is provided with a second inclined surface 107 between the stepped groove 106 and the connecting end 103, the diameter of the second inclined surface 107 gradually increases from the stepped groove 106 to the insertion end 102, providing a natural guide for the first positioning pin 1 to be inserted into the pin hole 201, avoiding the step groove 106 and the hole wall of the pin hole 201 from being stuck when the first positioning pin 1 is inserted into the pin hole 201 and hindering the insertion, thereby improving the smoothness and efficiency of assembly. At the same time, when the first positioning pin 1 slides out of the pin hole 201 due to external factors, since one end of the second inclined surface 107 extends to the stepped groove 106, under the guiding effect of the second inclined surface 107 along the hole wall of the pin hole 201, the hole wall of the pin hole 201 cooperates with the stepped surface of the stepped groove 106, avoiding the first positioning pin 1 from directly sliding out of the pin hole 201.

[0068] Specifically, the inclination angle of the second inclined surface 107 relative to the horizontal plane may be the same as or different from the inclination angle of the first inclined surface 104 relative to the horizontal plane. In the embodiment of the present application, no specific limitation is imposed on the inclination angles of the first inclined surface 104 and the second inclined surface 107.

[0069] In some embodiments of the present application, Figure 8 and Fig. 9 As shown, the first positioning pin 1 and the second positioning pin 3 are threadedly connected, the inner wall of the axial through hole 101 is provided with an internal thread 1011 , and the outer surface of the second positioning pin 3 is provided with an external thread 302 matched with the internal thread 1011 .

[0070] An internal thread 1011 is provided on the inner wall of the axial through hole 101, and an external thread 302 is provided on the outer surface of the second locating pin 3 corresponding to the internal thread 1011. When the second locating pin 3 is inserted into the axial through hole 101 and installed on the first locating pin 1, it is only necessary to tighten the second locating pin 3 so that the internal thread 1011 and the external thread 302 cooperate with each other, so that the first locating pin 1 and the second locating pin 3 can be connected. When the second locating pin 3 is removed from the first locating pin 1, it is only necessary to loosen the second locating pin 3 so that the internal thread 1011 and the external thread 302 are separated, and the second locating pin 3 can be removed. It can be easily installed or removed without special tools, which simplifies the assembly process and reduces the operating cost. In addition, the threaded connection is easy to disassemble and not easy to be damaged, which facilitates the reuse of the second locating pin 3, reduces material waste, and is economical and environmentally friendly.

[0071] Specifically, the internal thread 1011 can be set at the axial through hole 101 near the insertion end 102, or can be set on the inner wall of the entire axial through hole 101, or can be set at the axial through hole 101 near the connection end 103. In the embodiment of the present application, the specific position of the internal thread 1011 in the axial through hole 101 is not limited.

[0072] In some embodiments of the present application, Figure 4 and Figure 5 As shown, in the mating state, the length of the positioning end 301 of the second positioning pin 3 extending out of the insertion end 102 is 20 mm-100 mm.

[0073] In the mating state, the length of the positioning end 301 extending from the insertion end 102 is 20mm-100mm. Since the second positioning pin 3 is longer, when the second positioning pin 3 passes through the axial through hole 101 of the first positioning pin 1 and extends to the positioning hole of the target component, it can provide a deeper insertion depth, ensuring a more secure positioning and fixing effect. When facing installation objects of different thicknesses or depths, the longer second positioning pin 3 can adapt to a wider range of installation requirements, increasing the flexibility and versatility of the positioning pin assembly application.

[0074] In some embodiments of the present application, Fig. 9 and Fig.10 As shown, the area of ​​the circumferential cross section of the matching end 303 of the second positioning pin 3 is larger than the area of ​​the circumferential cross section of other regions of the second positioning pin 3 .

[0075] The area of ​​the circumferential cross-section of the mating end 303 of the second locating pin 3 is set to be larger than the area of ​​the circumferential cross-section of other areas of the second locating pin 3. When installing or removing the second locating pin 3, the operator can directly rotate the mating end 303 to complete the installation and removal of the second locating pin 3, which facilitates quick installation or removal and improves the convenience and efficiency of operation, especially in scenarios where the second locating pin 3 needs to be frequently adjusted or replaced.

[0076] Specifically, the mating end 303 may be designed with a wrench slot, a nut, a quick-release connector, etc. In the embodiment of the present application, no specific limitation is imposed on the structure of the mating end 303.

[0077] Exemplarily, the circumferential cross-section of the mating end 303 can be set to be an equilateral hexagon. When installing or removing the second locating pin 3, the operator can directly tighten or loosen the mating end 303 without tools to facilitate installation or removal of the second locating pin 3.

[0078] In some embodiments of the present application, Figure 5 and Figure 6As shown, in the mating state of the first positioning pin 1 and the second positioning pin 3 , the mating end 303 protrudes from the limiting portion 105 .

[0079] When the first positioning pin 1 is in a mating state with the second positioning pin 3 , the mating end 303 protrudes from the limiting portion 105 , so that an operator can directly operate the mating end 303 to conveniently remove the second positioning pin 3 from the first positioning pin 1 .

[0080] On this basis, an embodiment of the present application also provides a vehicle mounting device, including a mounting frame 2 and a positioning pin assembly.

[0081] Specifically, Figure 4 As shown, a pin hole 201 is provided on the mounting frame 2 .

[0082] Specifically, the connection end 103 of the first positioning pin 1 is installed at the pin hole 201 .

[0083] The vehicle mounting device provided by the embodiment of the present application inserts the insertion end 102 of the first locating pin 1 into the pin hole 201 of the mounting frame 2, and the positioning end 301 of the second locating pin 3 extends from the insertion end 102 of the first locating pin 1 through the axial through hole 101, and can deeply enter the positioning hole of the target component to ensure the positioning stability and assembly accuracy of the locating pin assembly. After the mounting frame 2 is assembled, since the first locating pin 1 and the second locating pin 3 are detachably connected, the cooperation between the first locating pin 1 and the second locating pin 3 can be cancelled, and the second locating pin 3 can be removed from the first locating pin 1, which can shorten the overall length of the locating pin assembly and reduce the weight of the locating pin assembly, providing sufficient installation space for the installation of other components, and the removed second locating pin 3 can also be recycled to save costs.

[0084] Specifically, a turning hole 203 may be further provided on the mounting frame 2 , and when the transverse tube 4 is mounted on the mounting frame 2 , the transverse tube 4 may be fixed at the turning hole 203 .

[0085] Specifically, mounting holes 202 may be further provided around the mounting frame 2 so that the fasteners cooperate with the mounting holes 202 to fix the mounting frame 2 .

[0086] It should be noted that the vehicle in this application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the car model, the car in this application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other models. Generally, a vehicle is provided with wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.

[0087] It should be noted that in the embodiments of the present application, the type of the power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.

[0088] The working principle of the vehicle installation device in this embodiment is described as follows:

[0089] First, fix the cross tube 4 at the turned hole 203 of the mounting frame 2 by welding, and then insert the insertion end 102 of the first locating pin 1 into the pin hole 201 of the mounting frame 2, so that the connecting end 103 of the first locating pin 1 is installed at the pin hole 201, and the limiting portion 105 of the first locating pin 1 abuts against the mounting frame 2, and the first locating pin 1 and the mounting frame 2 are welded and fixed.

[0090] Insert the positioning end 301 of the second positioning pin 3 from the connecting end 103 of the first positioning pin 1 into the axial through hole 101. Since the axial through hole 101 is provided with an internal thread 1011, the outer surface of the second positioning pin 3 is provided with an external thread 302. By tightening the second positioning pin 3, the second positioning pin 3 is assembled on the first positioning pin. The positioning end 301 of the second positioning pin 3 extends out of the axial through hole 101 from the insertion end 102 of the first positioning pin 1, and can deeply enter the positioning hole of the target component, ensuring the positioning stability and assembly accuracy of the positioning pin assembly. Then install the fastener at the mounting hole 202 to fix the mounting frame 2.

[0091] After the mounting frame 2 is assembled, the second locating pin 3 is loosened and removed from the first locating pin 1. This can shorten the overall length of the locating pin assembly and reduce the weight of the locating pin assembly, thereby providing sufficient installation space for the installation of other components. At the same time, the removed second locating pin 3 can be reused during the next installation, saving costs.
