Description

Technical Field

[0001] The present invention relates to the technical field of automobile logos, and in particular to a rotating, fixing, and installing mechanism for an automobile logo. Background Art

[0002] With the continuous improvement of automobile safety standards, automobile logos, as external protruding parts, must be able to undergo reasonable deformation or displacement when subjected to rated external forces to avoid harm to people. At the same time, they must take into account installation stability and maintenance convenience. Automobile external parts should be able to stretch, fall off or bend when subjected to force, and there are strict restrictions on the height of the remaining parts.

[0003] Currently, there are two main technical solutions for automobile logos on the market. The first is the force-bearing flip-up logo, which achieves external force buffering through a flipping structure. However, its design relies on the precise coordination of multiple parts, which requires extremely high assembly accuracy and has special requirements for the size of the car body sheet metal, resulting in high production costs. In addition, the complex structure makes it easy for it to fail due to parts wear during long-term use.

[0004] Rigid fixed signpost: It is directly fixed to the car body with a rigid structure. Although the structure is simple, it is prone to breakage or falling off when subjected to force, and it cannot be repaired after damage, and the maintenance performance is extremely poor. At the same time, the rigid connection cannot achieve external force buffering, posing a safety hazard.

[0005] The core defect of the existing technology is that it is impossible to achieve the synergistic effect of "rotational freedom" and "elastic preload" in the signpost installation structure. The signpost needs to maintain a stable installation posture under normal conditions, and it needs to be able 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 provides a rotating, fixing and installing mechanism for a car logo.

[0007] In order to overcome the defects in the background technology, the present invention solves the technical problem by adopting the following technical solution: a rotating fixed installation mechanism for a car vertical emblem, comprising a base with an installation cavity formed therein, wherein a spherical installation seat is arranged in the installation cavity; A spherical connector, the lower end of which is formed with a connecting groove, and the closed surface of the upper end of which is provided with a connecting socket that is in communication with the connecting groove; The upper end of the ball mounting seat is concave to form a ball groove, and the ball groove is precisely matched with the outer spherical surface of the ball connector, allowing the ball connector to rotate in the ball groove; The car logo body has a car logo plug provided at its lower part. The shape of the car logo plug matches the connecting socket. The car logo plug is placed in the connecting groove through the connecting socket to realize the axial positioning of the car logo body and the spherical connecting piece. The spring connection mechanism is arranged in the mounting cavity, one end of which is connected to the vehicle 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 telescopic deformation keeps the vehicle logo plug and the ball mounting seat in a reverse pre-tightened state, thereby ensuring that the ball connector is always within the constraint range of the ball groove.

[0008] Further improvements include a ball mounting seat axially sliding in the mounting cavity, allowing the ball mounting seat to reciprocate along the axis of the base, and an axial reset mechanism is also provided in the mounting cavity for providing elastic support force to the ball mounting seat.

[0009] Further improvements include that the axial reset mechanism includes a large spring, a guide sleeve and a limit clamp, one end of the large spring abuts the lower end of the spherical mounting seat and the other end abuts the guide sleeve, the limit clamp is embedded in the groove opened on the inner wall of the mounting cavity, the limit clamp and the guide sleeve have an interference fit to limit the guide sleeve from falling out, and is used to provide reverse support force for the large spring.

[0010] Further improvements include that the spring connection mechanism includes a small spring, the rear end of the small spring forms an extension portion extending along the central axis of the small spring toward the front end of the small spring, the free end of the extension portion is constructed into a hook-shaped structure, the hook-shaped structure is hooked with the opening on the vehicle logo plug through a connecting hole axially opened on the spherical mounting seat, and the front end of the small spring is against the lower end of the spherical mounting seat.

[0011] A further improvement includes providing a disassembly opening on the closed surface of the upper end of the spherical connector, wherein the disassembly opening is intersected with the connecting socket.

[0012] A further improvement includes providing at least two positioning protrusions on the spherical surface of the ball connector, wherein the positioning protrusions match with matching grooves provided on the inner wall of the ball groove, thereby achieving positioning installation of the vehicle logo body.

[0013] A further improvement includes a detachable connection between the base and the base.

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

[0015] A further improvement includes sleeves of plastic parts on the ends of the clamp arms.

[0016] The beneficial effects of the present invention are: this design realizes the stable installation of the standing sign under normal conditions through the rotation of the spherical connector and the coordination of 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 maintenance or high assembly precision requirements of the existing standing sign structure. It has both safety, reliability and easy maintenance. When subjected to rated external force, it can overcome the restraining force to avoid the falling off of the standing sign and injury to personnel, and will not cause damage to its structure. It is not only easy to install and remove, but also can prevent loss and theft. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art without creative effort based on the embodiments of the present invention are within the scope of protection of the present invention.

[0020] refer to Figure 1 and Figure 14 A rotating fixed installation mechanism for a car vertical emblem includes a base 2 with an installation cavity formed therein, wherein a spherical installation seat 4 is provided in the installation cavity; refer to Figure 5 and Figure 6 The spherical connector 3 has a connecting groove 304 at its lower end for receiving the car logo plug 11 on the car logo body 1 , and a connecting socket 302 in communication with the connecting groove 304 is provided on the closed surface of its upper end, so that the car logo plug 11 can be placed in the connecting groove 304 through the connecting socket 302 ; refer to Figure 3 and Figure 4 The ball mounting seat 4 has an upper end that is concave to form a ball groove 401. The ball groove 401 is precisely matched with the outer spherical surface of the ball connector 3, allowing the ball connector 3 to rotate in the ball groove 401. refer to Figure 7 and Figure 8 The car logo body 1 has a car logo plug 11 at its lower part. The shape of the car logo plug 11 matches the connecting socket 302. The car logo plug 11 is placed in the connecting groove 304 through the connecting socket 302 to realize the axial positioning of the car logo body 1 and the ball connector 3. The spring connection mechanism 5 is arranged in the mounting cavity, one end of which is connected to the vehicle logo plug 11, and the other end abuts against the lower end of the ball mounting seat 4 to form an elastic support. The elastic restoring force generated by the axial telescopic deformation keeps the vehicle logo plug 11 and the ball mounting seat 4 in a reverse pre-tightened state, thereby ensuring that the ball connector 3 is always within the constraint range of the ball groove 401, thereby ensuring the stability and reliability of the entire connection structure.

[0021] In this embodiment, a ball mounting seat 4 is axially slidingly provided in the mounting cavity, allowing the ball mounting seat 4 to reciprocate along the axial direction of the base 2. An axial reset mechanism is also provided in the mounting cavity for providing elastic support force to the ball mounting seat 4 so that the ball mounting seat 4 remains in the mounting cavity. This design ensures that the vehicle logo body 1 always maintains a standard installation posture perpendicular to the hood when there is no external force, 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 limit clamp 7. One end of the large spring 6 abuts against the lower end of the spherical mounting seat 4, and the other end abuts against the guide sleeve 10. The limit clamp 7 is embedded in the groove opened on the inner wall of the mounting cavity. The limit clamp 7 and the guide sleeve 10 have an interference fit to limit the escape of the guide sleeve 10, which is used to provide reverse support force for the large spring 6. The guide sleeve 10 plays a guiding role on the spring connection mechanism 5.

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

[0024] For further examples, see Figure 5 and Figure 6 A disassembly opening 301 is provided on the closed surface of the upper end of the spherical connector 3, and the disassembly opening 301 and the connecting socket 302 are intersected. With this design, the vehicle logo can be disassembled quickly and effectively, that is, by pulling the vehicle logo body 1, the vehicle logo plug 11 on the vehicle logo body 1 and the hook-shaped structure 501 pass through the disassembly opening 301 and the connecting socket 302, thereby completing the disassembly between the vehicle logo plug 11 and the spring connecting mechanism 5.

[0025] In this embodiment, in order to ensure that the vehicle logo 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 with the matching grooves 403 opened on the inner wall of the ball groove 401, thereby realizing the positioning and installation of the vehicle logo body 1. When the vehicle logo body 1 is subjected to external force, the positioning protrusions 303 can automatically disengage from the matching grooves 403, thereby preventing the vehicle logo body 1 or the car panel from being damaged due to hard force. The positioning protrusions 303 can be used to press against the inner wall of the ball groove 401 to realize the positioning of the vehicle logo body 1 after flipping.

[0026] In this embodiment, reference Figure 11 and Figure 12 The base 2 is detachably connected to the base 9 so that the base 2 cooperates with the base 9 to realize the detachable installation of the car hood. The base 9 includes a ring body 901 and a clamp arm 903 symmetrically arranged on the ring body 901. The opposite surface of the clamp arm 903 is provided with a locking tooth 902, and the locking tooth 902 is engaged with the embedding groove 202 provided on the outer surface of the base 2, thereby realizing the stable installation of the base 9 on the base 2. A gripping portion for gripping is formed on the ring body 901, and the clamp arm 903 is driven to rotate by gripping the gripping portion.

[0027] For further examples, see 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 embedding groove 202 to enhance the structural strength. When the locking tooth 902 of the clamp arm 903 is against the surface of the base 2, the locking tooth 902 is made to slide along the surface of the base 2 by rotating the base 9, and finally is locked into the embedding groove 202 to complete the locking. The locking tooth 902 is axially limited by the reinforcing rib 201 to ensure the stability of the base 9 after being connected to the base 2. The L-shaped reinforcing rib 201 is used to limit the locking tooth 902 axially and rotationally.

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

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

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
