Description

Technical Field

[0001] This invention relates to the field of automotive emblem technology, and more particularly to a rotating and fixing mechanism for automotive emblems. Background Technology

[0002] As automotive safety standards continue to improve, automotive emblems, as external protruding components, must be able to undergo reasonable deformation or displacement when subjected to rated external force to avoid injury to personnel. At the same time, they must also take into account installation stability and ease of maintenance. Relevant regulations in China and the European Union clearly require that external automotive parts should be able to expand, detach, or bend under force, and there are strict limits on the height of the remaining parts.

[0003] Currently, there are two main technical solutions for car emblems on the market: the force-flipping emblem, which uses a flipping structure to buffer external forces, but its design relies on the precise cooperation of multiple parts, requiring extremely high assembly precision and special requirements for the body sheet metal dimensions, resulting in high production costs; in addition, the complex structure makes it prone to failure due to wear and tear of parts during long-term use.

[0004] Rigid fixed hood: It is directly fixed to the vehicle body with a rigid structure. Although the structure is simple, it is prone to breakage or falling off when subjected to force, and cannot be repaired after damage, resulting in extremely poor maintainability. At the same time, the rigid connection cannot buffer external forces, posing a safety hazard.

[0005] The core defect of existing technology is that it cannot achieve the synergistic effect of "rotational freedom" and "elastic preload" in the sign installation structure. It is necessary for the sign to maintain a stable installation posture under normal conditions, and to avoid hard damage through reasonable rotation or displacement when subjected to force. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned defects and provide a rotating and fixing mechanism for automobile emblems.

[0007] In order to overcome the defects in the background art, the technical solution adopted by the present invention to solve its technical problem is: a car emblem rotating and fixing mounting mechanism, including a base, which has an installation cavity inside, and a ball mounting seat is provided in the installation cavity; A spherical connector has a connecting groove at its lower end and a connecting socket that communicates with the connecting groove on its upper closed surface. The ball mounting base has an indentation at its upper end to form a ball groove, which is precisely fitted with the outer spherical surface of the ball connector, allowing the ball connector to rotate within the ball groove; The logo body has a logo plug at its lower part. The shape of the logo plug matches the connection socket. The logo plug is inserted into the connection groove through the connection socket to achieve axial positioning of the logo body and the ball connector. A spring connecting mechanism is installed in the mounting cavity. One end of the spring is connected to the logo plug, and the other end abuts against the lower end of the ball mounting seat to form an elastic support. The elastic restoring force generated by the axial expansion and contraction deformation keeps the logo plug and the ball mounting seat in a reverse pre-tight state, thereby ensuring that the ball connector is always within the constraint range of the ball groove.

[0008] Further improvements include an axially sliding ball mounting seat within the mounting cavity, allowing the ball mounting seat to reciprocate along the base axis, and an axial reset mechanism within the mounting cavity to provide elastic support for the ball mounting seat.

[0009] Further improvements include the axial reset mechanism comprising a large spring, a guide sleeve, and a limiting clamp. One end of the large spring abuts against the lower end of the ball mounting base, and the other end abuts against the guide sleeve. The limiting clamp is embedded in a groove opened on the inner wall of the mounting cavity. The limiting clamp and the guide sleeve are interference-fitted to restrict the guide sleeve from dislodging and to provide a reverse support force for the large spring.

[0010] Further improvements include the spring connecting mechanism comprising a small spring, the rear end of which forms an extension extending along the central axis of the small spring toward the front end of the small spring, the free end of which is constructed into a hook-shaped structure, the hook-shaped structure being hooked to the opening on the car logo plug through a connecting hole axially through the ball mounting base, and the front end of the small spring abutting against the lower end of the ball mounting base.

[0011] Further improvements include a disassembly port on the closed surface at the upper end of the spherical connector, wherein the disassembly port intersects with the connection port.

[0012] Further improvements include providing at least two positioning protrusions on the spherical surface of the ball connector, wherein the positioning protrusions match the matching grooves opened on the inner wall of the ball groove, thereby realizing the positioning and installation of the car logo body.

[0013] Further improvements include a detachable connection between the base and the substructure.

[0014] Further improvements include the base comprising a ring body and clamp arms symmetrically arranged on the ring body, wherein the opposite surfaces of the clamp arms are provided with locking teeth, and the locking teeth engage with grooves opened on the outer surface of the base, thereby achieving a stable installation of the base on the base.

[0015] Further improvements include fitting a plastic part to the end of the clamp arm.

[0016] The beneficial effects of this invention are: This design achieves stable installation of the signpost under normal conditions through the rotation of the ball connector and the spring connection mechanism. At the same time, it can avoid hard damage by rotation when subjected to rated external force, solving the problems of easy breakage, poor maintainability, or high assembly precision requirements of existing signpost structures. It has the advantages of safety, reliability, and easy maintenance. When subjected to rated external force, it can overcome the constraint force to prevent the signpost from falling off and causing injury to personnel, and it will not cause damage to its structure. It is not only easy to install and remove, but also prevents loss and theft. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] refer to Figure 1 and Figure 14 A rotating and fixing mechanism for a car emblem includes a base 2 with an internal mounting cavity, and a spherical mounting seat 4 is disposed within the mounting cavity. refer to Figure 5 and Figure 6 The ball connector 3 has a connecting groove 304 at its lower end for receiving the car logo plug 11 on the car logo body 1. The upper closed surface of the ball connector 3 has a connecting port 302 that communicates with the connecting groove 304, so that the car logo plug 11 can be placed in the connecting groove 304 through the connecting port 302. refer to Figure 3 and Figure 4 The ball mounting base 4 has an indented upper end to form a ball groove 401. The ball groove 401 is precisely fitted with the outer spherical surface of the ball connector 3, allowing the ball connector 3 to rotate within the ball groove 401. refer to Figure 7 and Figure 8 The logo body 1 has a logo plug 11 at its lower part. The logo plug 11 is shaped to match the connection socket 302. The logo plug 11 is inserted into the connection groove 304 through the connection socket 302 to achieve axial positioning of the logo body 1 and the ball connector 3. The spring connecting mechanism 5 is arranged in the mounting cavity. One end of it is connected to the logo plug 11, and the other end abuts against the lower end of the ball mounting seat 4 to form an elastic support. Through the elastic restoring force generated by the axial expansion and contraction deformation, the logo plug 11 and the ball mounting seat 4 are kept in a reverse pre-tight state, thereby ensuring that the ball connector 3 is always within the constraint range of the ball groove 401, thus ensuring the stability and reliability of the entire connection structure.

[0021] In this embodiment, a ball mounting seat 4 is axially slidably provided in the mounting cavity, allowing the ball mounting seat 4 to reciprocate along the axis of the base 2. An axial reset mechanism is also provided in the mounting cavity to provide elastic support for the ball mounting seat 4 so that the ball mounting seat 4 is kept in the mounting cavity. This design ensures that the car logo body 1 always maintains a standard mounting posture perpendicular to the hood when no external force is applied, avoiding displacement caused by gravity or slight vibration.

[0022] In this embodiment, reference Figure 1 , Figure 9 and Figure 10 The axial reset mechanism includes a large spring 6, a guide sleeve 10, and a limiting clamp 7. One end of the large spring 6 abuts against the lower end of the ball mounting base 4, and the other end abuts against the guide sleeve 10. The limiting clamp 7 is embedded in a groove opened on the inner wall of the mounting cavity. The limiting clamp 7 and the guide sleeve 10 are interference-fitted to restrict the guide sleeve 10 from dislodging and to provide reverse support force for the large spring 6. The guide sleeve 10 plays a guiding role for the spring connecting mechanism 5.

[0023] In this embodiment, reference Figure 2 The spring connecting mechanism 5 includes a small spring 502. The rear end of the small spring 502 forms an extension 503 that extends along the central axis of the small spring 502 toward the front end of the small spring 502. The free end of the extension 503 is constructed as a hook-shaped structure 501. The hook-shaped structure 501 is hooked to the opening on the logo plug 11 through a connecting hole 402 that is axially opened on the ball mounting base 4. The front end of the small spring 502 abuts against the lower end of the ball mounting base 4. With this design, the elastic force generated by the small spring 502 pulls the logo body 1 so that the ball connector 3 is always kept in the ball groove 401.

[0024] Further embodiments are described in reference to... Figure 5 and Figure 6 The upper closed surface of the ball connector 3 is provided with a disassembly port 301. The disassembly port 301 and the connection port 302 are intersected and distributed. With this design, the car logo can be disassembled quickly and effectively. That is, by pulling the car logo body 1, the car logo plug 11 on the car logo body 1 and the hook structure 501 pass through the disassembly port 301 and the connection port 302 together, thereby completing the disassembly and reassembly between the car logo plug 11 and the spring connection mechanism 5.

[0025] In this embodiment, to ensure that the car emblem body 1 maintains the preset installation position, refer to Figure 5 and Figure 6At least two positioning protrusions 303 are provided on the spherical surface of the ball connector 3. The positioning protrusions 303 match the matching grooves 403 opened on the inner wall of the ball groove 401, thereby realizing the positioning and installation of the car logo body 1. When the car logo body 1 is subjected to external force, the positioning protrusions 303 can automatically disengage from the matching grooves 403, thereby preventing the car logo body 1 or the car panel from being damaged due to hard force. The positioning protrusions 303 can also be used to press against the inner wall of the ball groove 401 to realize the positioning of the car logo body 1 after it is flipped.

[0026] In this embodiment, reference Figure 11 and Figure 12 The base 2 and the base 9 are detachably connected so that the base 2 and the base 9 cooperate to achieve detachable installation of the car engine hood clamp. The base 9 includes a ring 901 and clamping arms 903 symmetrically arranged on the ring 901. The opposite side of the clamping arms 903 is provided with locking teeth 902. The locking teeth 902 are engaged with the grooves 202 opened on the outer surface of the base 2, thereby achieving a stable installation of the base 9 on the base 2. The ring 901 is formed with a gripping part for holding, and the clamping arms 903 are rotated by holding the gripping part.

[0027] Further embodiments are described in reference to... Figure 13 The base 2 is provided with an L-shaped reinforcing rib 201, and the reinforcing rib 201 is arranged around the edge of the groove 202 to enhance the structural strength. When the locking tooth 902 of the clamp arm 903 abuts against the surface of the base 2, the locking tooth 902 slides along the surface of the base 2 by rotating the base 9, and finally locks into the groove 202. The axial limit of the locking tooth 902 by the reinforcing rib 201 ensures the stability after the base 9 is connected to the base 2. The L-shaped reinforcing rib 201 is used to limit the axial and rotational movement of the locking tooth 902.

[0028] In a further embodiment, the tooth surface of the locking tooth 902 forms an inclined angle of 5°-10° with the horizontal plane. This angle range has been verified by mechanical simulation to ensure optimal axial transmission efficiency. The inner limiting surface of the L-shaped reinforcing rib 201 is designed as an inclined guide structure that perfectly matches the tooth surface of the locking tooth 902. The two are precision-machined to form a high-precision mating surface. When the base 9 rotates around the rotation center, the inclined tooth surface of the locking tooth 902 slides along the limiting surface of the L-shaped reinforcing rib 201. This angled contact motion causes the base 9 to generate axial feed motion synchronously during rotation. This design utilizes the inclined plane transmission principle to convert rotational motion into axial displacement, creating a dynamic pre-tightening process between the base 9 and the base 2. Compared with the traditional vertical mating structure, it can improve the uniformity of pre-tightening force by more than 30%, effectively enhancing the fixing effect on the car hood and ensuring connection stability under complex working conditions.

[0029] In a further embodiment, a plastic part 8 is fitted onto the end of the clamp arm 903. The plastic part 8 can prevent wear between the clamp arm 903 and the mounting surface of the car hood.

[0030] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
