Description

Technical Field

[0001] The utility model relates to the technical field of mechanical rotation, in particular to a rotation structure and a vehicle audio. Background Art

[0002] In the field of modern consumer goods, especially in vehicle audio systems, higher requirements are put forward for the functionality and space utilization rate of the rotation structure. Vehicle audio sometimes needs to be designed as a retractable structure to save space (such as hidden in the instrument panel) or extended when needed (such as rotating and extending to obtain better acoustic effects). Generally, vehicle audio includes a housing, an audio sound module, a light-emitting ring, and a rotation structure provided on the housing. A common solution for such a rotation structure is a screw drive structure, which converts linear motion in screw motion through thread fitting (thereby achieving retraction and extension). However, the existing conventional screw drive structure has a significant limitation: its motion form is usually single, that is, the motion is locked / stopped after retraction and extension are in place, which cannot meet the application requirements of some "phased actions". For example, after extension, it can continue to rotate, thereby improving the user experience. Therefore, in view of the above problems, it is necessary to propose a new solution. Summary of the Utility Model

[0003] In view of this, in view of the defects of the prior art, the main purpose of the utility model is to provide a rotation structure and a vehicle audio, and its function is to solve the above problems.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions:

[0005] In the first aspect, a rotation structure includes a base, a connecting member, an elastic member, a rotating seat, and a driving mechanism; the connecting member and the elastic member are both sleeved on the base, the elastic member acts on the connecting member so that the connecting member rotatably abuts against the front end of the base, and at least one spiral guiding portion is provided on the outer peripheral side wall of the connecting member;

[0006] The rotating seat is sleeved on the connecting member in a screw-rotatable manner, the inner wall of the rotating seat has internal threads, and stop portions corresponding to the number and positions of the foregoing spiral guiding portions are provided in the thread grooves at the ends of the internal threads. The internal threads are screwed and connected with the foregoing spiral guiding portions. When the rotating seat rotates forward and screws in place, the stop portions abut against the corresponding spiral guiding portions in the circumferential direction; the driving mechanism drives the rotating seat to rotate.

[0007] As a preferred solution, the elastic member is a spring, the spring and the connecting member are sleeved on the base in sequence, the end of the spring abuts against the end of the base, the end of the connecting member abuts against the front end of the spring, and the front end of the connecting member abuts against the front end of the base.

[0008] As a preferred solution, a rotatable metal washer is provided at the end of the connecting member, and the front end of the spring abuts against the metal washer correspondingly.

[0009] As a preferred solution, a detachable stopper is provided at the front end of the base. The inner side wall of the stopper has a plurality of L-shaped clamping grooves. Correspondingly, the outer peripheral side surface at the front end of the base has a plurality of clamping protrusions, and the clamping protrusions are snapped into the L-shaped clamping grooves, and the front end of the connecting member abuts against the stopper.

[0010] As a preferred solution, the end of the internal thread has screwing ports corresponding to the number and position of the aforementioned spiral guiding portions. A stop screw is provided at each screwing port, and the rod body of each stop screw extends into the thread groove of the internal thread to form the aforementioned stop portion.

[0011] As a preferred solution, the outer peripheral side wall of the rotating seat has a toothed portion, the driving mechanism is a motor, and the output end of the motor is connected with a spur gear, and the spur gear meshes with the toothed portion.

[0012] In a second aspect, a vehicle audio includes a housing, an audio sound generation module, a light-emitting ring, a decorative ring, a grille, and a rotating structure as described in the first aspect provided on the housing. The base has an accommodating space penetrating in the axial direction, the audio sound generation module is arranged in the accommodating space, the light-emitting ring is arranged on the front side of the housing and surrounds the rotating seat, and the decorative ring and the grille are both arranged at the front end of the rotating seat and rotate along with the rotating seat.

[0013] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions, the main points are as follows;

[0014] Through the screwing fit between the spiral guiding portion and the internal thread, the rotating seat realizes an axial spiral telescopic movement; when the rotating seat extends forward in place, the stop portion abuts against the spiral guiding portion circumferentially to limit its further forward movement, but allows the driving mechanism to continue driving the rotating seat to rotate in place. At this time, the connecting member will also be driven by the rotating seat to rotate. This structure breaks through the limitation of the single telescopic function of the traditional spiral mechanism, and can still perform a rotating action after the telescopic movement is in place, expands the application scenarios, and improves the user experience.

[0030] Please refer to Figures 4 to 10 , an embodiment of the present utility model provides a rotating structure, including a base 10, a connecting member 20, an elastic member 30, a rotating seat 40 and a driving mechanism 50; the connecting member 20 and the elastic member 30 are both sleeved on the base 10, and the elastic member 30 acts on the connecting member 20 so that the connecting member 20 rotatably abuts against the front end of the base 10, and at least one spiral guiding portion 21 is provided on the outer peripheral side wall of the connecting member 20;

[0031] The rotating seat 40 is sleeved on the connecting member 20 in a screw-rotatable manner, the inner wall of the rotating seat 40 has an internal thread 41, and a stop portion 42 corresponding to the number and position of the aforementioned spiral guiding portions 21 is provided in the thread groove at the end of the internal thread 41. The internal thread 41 is screwed and connected with the aforementioned spiral guiding portion 21. After the rotating seat 40 rotates forward in a screw manner to the in-place position, the stop portion 42 abuts against the corresponding spiral guiding portion 21 in the circumferential direction; the driving mechanism 50 drives the rotating seat 40 to rotate.

[0032] Through the screw engagement of the spiral guiding portion 21 and the internal thread 41, the rotating seat 40 realizes an axial screw telescopic movement; when the rotating seat 40 extends forward to the in-place position, the stop portion 42 is in circumferential contact with the spiral guiding portion 21, restricting its further forward movement, but allowing the driving mechanism 50 to continue to drive the rotating seat 40 to rotate in place. At this time, the connecting member 20 will also be driven by the rotating seat 40 to rotate. This structure breaks through the limitation of the single telescopic function of the traditional screw mechanism, and can still perform a rotating action after the telescopic in-place, expanding the application scenario and improving the user experience.

[0033] Further, the elastic member 30 is a spring. The spring and the connecting member 20 are sequentially sleeved on the base 10. The end of the spring abuts against the end of the base 10, the end of the connecting member 20 abuts against the front end of the spring, and the front end of the connecting member 20 abuts against the front end of the base 10. The spring pushes the connecting member 20 to axially press against the front end of the base 10, ensuring that the connecting member 20 maintains a stable axial limit during the rotation of the rotating seat 40 and avoiding displacement caused by vibration or load.

[0034] Further, a rotatable metal washer 22 is provided at the end of the connecting member 20. The front end of the spring abuts against the metal washer 22 correspondingly. The metal washer 22 serves as a low-friction interface between the spring and the connecting member 20, reducing the rotational resistance, preventing the end face of the spring from wearing the connecting member 20, and enhancing the service life and operation smoothness of the connecting member 20.

[0035] Further, a detachable stopper 60 is provided at the front end of the base 10. The inner side wall of the stopper 60 has a plurality of L-shaped clamping grooves 61. Correspondingly, the outer peripheral side surface at the front end of the base 10 has a plurality of clamping protrusions 11. The clamping protrusions 11 are snapped into the L-shaped clamping grooves 61. The front end of the connecting member 20 abuts against the stopper 60. The detachable stopper 60 is clamped to the base 10 through the L-shaped clamping grooves, realizing quick disassembly and assembly. Meanwhile, it serves as the axial limiting surface of the connecting member 20, simplifying the machining complexity at the front end of the base 10 and reducing the manufacturing cost.

[0036] Further, the end of the internal thread 41 has screw-in ports 411 corresponding to the number and positions of the aforementioned spiral guiding portions 21. A stop screw is provided at each screw-in port 411. The rod body of each stop screw extends into the thread groove of the internal thread 41 to form the aforementioned stop portion 42. This design does not require customizing complex thread structures and molds, directly using standardized screw parts, and reducing the cost.

[0037] Further, the outer peripheral side wall of the rotating seat 40 has a toothed portion 43. The driving mechanism 50 is a motor. The output end of the motor is connected with a spur gear 51. The spur gear 51 meshes with the toothed portion 43. The spur gear 51 meshes with the toothed portion 43 on the outer wall of the rotating seat 40, realizing the transmission control of the motor on the rotating seat 40, and not only can rotation be achieved but also spiral rotation can be achieved.

[0038] Referring to Figures 1 - 3 , the present utility model further provides a vehicle audio, including a housing 71, an audio sound generation module (not shown in the figure), a light-emitting ring 72, a decorative ring 73, a grille 74, and the aforementioned rotating structure provided on the housing 71. The base 10 has an accommodation space 12 penetrating along the axial direction. The audio sound generation module is arranged in the accommodation space 12. The light-emitting ring 72 is arranged on the front side of the housing 71 and surrounds the rotating seat 40. The decorative ring 73 and the grille 74 are both arranged at the front end of the rotating seat 40 and rotate along with the rotating seat 40. Thus, after the rotating seat 40 extends in place, it can drive the decorative ring 73 and the grille 74 to continue rotating continuously. It should be noted here that the decorative ring 73 and the grille 74 are connected to the rotating seat 40 by means of snap fit or interference fit, which is the prior art and will not be elaborated here. In addition, the aforementioned rotating structure can be applied to other products in addition to being used in vehicle audio products, not limited thereto.
