Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rotating shaft accessories, and in particular to a key type automatic pop-up rotating shaft. BACKGROUND

[0002] Rotating shafts, as a kind of basic mechanical connecting components, are widely used in products that require relative rotation of two parts, such as flip phones, battery compartment covers, charging boxes, earphone boxes, and cosmetic mirrors. The core function of a rotating shaft is to provide stable rotation support and reliable positioning at a specific position (such as the open or closed state), which is crucial for the convenience of use, operation experience, and overall quality of the product.

[0003] Currently, the rotating shafts commonly used in such products on the market mainly rely on manual operation to achieve the opening and closing function. Users need to directly apply force with their hands to open or close the device. Although some rotating shaft designs may include simple buckles or magnetic structures to assist in positioning, the core rotation process itself does not have automatic driving capability, which means that both opening and closing actions require full manual operation and sufficient force from the user.

[0004] Such manual operation type rotating shafts are cumbersome to open and close, lack convenience, and require the user to precisely align the components and apply force to complete the entire opening and closing process. Frequent manual operation is cumbersome, especially in scenarios that require quick or one-handed operation (such as opening a flip phone while holding an object), which is inconvenient and results in a poor user experience.

[0027] Example 1 Referring to Figures 1-8 The application provides a key type automatic closing and opening rotating shaft, comprising a shell 1, an inner cam 2, an outer cam 3, a first elastic member 4 and a pressing member 5, wherein the shell 1 is hollow and has an opening at one end, the inner cam 2 is arranged in the shell 1 and can slide along the length direction of the shell 1, the outer cam 3 is rotatably arranged on the end of the shell 1 with the opening, the first elastic member 4 is arranged in the shell 1 and located on the side of the outer cam 3 away from the inner cam 2, and the pressing member 5 is arranged on the outer cam 3 and can slide on the outer cam 3 away from or close to the inner cam 2; A first inclined meshing surface 17 is spirally arranged on the side of the outer cam 3 facing the inner cam 2, and a second inclined meshing surface 18 is spirally arranged on the side of the inner cam 2 facing the outer cam 3, the first meshing surface 17 and the second meshing surface 18 are both distributed in one direction for 180 degrees, and the first meshing surface 17 and the second meshing surface 18 are meshed when the outer cam 3 and the inner cam 2 are installed; A clamping groove 20 is formed on the outer cam 3, and the clamping groove 20 is located on the end of the first meshing surface 17 facing the inner cam 2, and a clamping block 21 is integrally formed on the inner cam 2, and the clamping block 21 is located on the end of the second meshing surface 18 facing the outer cam 3; When rotating the outer cam 3, the first engaging surface 17 of the outer cam 3 presses the second engaging surface 18 of the inner cam 2, so that the inner cam 2 moves towards the first elastic member 4, the first elastic member 4 is compressed, and a restoring force for moving the inner cam 2 towards the outer cam 3 is generated. When the outer cam 3 is continuously rotated, the inner cam 2 moves towards the first elastic member 4 to the maximum distance, at which time the clamping block 21 on the second engaging surface 18 is clamped into the clamping groove 20 of the first engaging surface 17, and the outer cam 3 and the inner cam 2 reach a balance. When the external force is removed, the outer cam 3 and the inner cam 2 are relatively prohibited, so as to limit the rotation of the outer cam 3. When it is desired to rotate the outer cam 3, the pressing member 5 is directly triggered to move towards the clamping block 21 until the clamping block 21 is disengaged from the clamping groove 20. At this time, the compressed first elastic member 4 can push the inner cam 2 to move towards the outer cam 3. Due to the existence of the first engaging surface 17 and the second engaging surface 18, the outer cam 3 will rotate counterclockwise to rotate back to the initial state.

[0028] The first engaging surface 17 of the outer cam 3 is slidably connected with the second engaging surface 18 of the inner cam 2, so that when the outer cam 3 is manually rotated, the inner cam 2 can be pressed to move towards the first elastic member 4. At this time, the first elastic member 4 is compressed and stored. When the first engaging surface 17 and the second engaging surface 18 reach the top point after being rotated by 180 degrees, the clamping block 21 is embedded into the clamping groove 20, so as to achieve locking, and the inner cam 2 and the outer cam 3 reach a balance. When the outer cam 3 is rotated by the external force, the outer cam 3 remains stable and does not rotate. When it is desired to rotate the outer cam 3, the pressing member 5 is manually pressed to move towards the clamping block 21, so that the clamping block 21 and the clamping groove 20 are disengaged. At this time, the first elastic member 4 releases the ability to drive the outer cam 3 to rotate automatically, and the inner cam 2 moves towards the outer cam 3 until the first engaging surface 17 and the second engaging surface 18 return to the initial state of complete engagement. Thus, the outer cam 3 is automatically rotated by simple pressing, and the automatic opening is achieved. The operation of the traditional rotating shaft is manually operated throughout the process, which is complicated and rigid. The convenience of opening and closing the cover device is improved, the user experience is improved, the structure is simple, the cost is low, the space requirement is small, and the manufacturing is easy.

In order to facilitate the placement of the pressing button 52, the outer cam 3 is provided with a sliding groove 7 which is arranged on the side of the outer cam 3 which is away from the inner cam 2, and the sliding hole 8 is arranged at the groove bottom of the sliding groove 7 so as to communicate with the inside of the sliding groove 7, and a part of the pressing button 52 is arranged in the sliding groove 7 and can slide in the sliding groove 7 towards or away from the inner cam 2, and the other part is arranged outside the sliding groove 7, which is convenient for the user to press.

[0030] When the user presses the pressing button 52, the pressing button 52 will move towards the pressing cam 51, thereby driving the pressing cam 51 to move towards the inner cam 2, until the inclined surface 19 of the pressing cam 51 is flush with the first meshing surface 17 of the edge of the clamping groove 20, at which time the disengagement inflection point is reached, the first elastic member 4 releases the ability to drive the inner cam 2 to move towards the outer cam 3, and the outer cam 3 rotates counterclockwise to rotate back to the initial state.

[0031] Further, the pressing member 5 further comprises a second elastic member 6 which is arranged in the sliding groove 7, one end of the second elastic member 6 abuts against the groove bottom of the sliding groove 7, and the other end abuts against the wall of the pressing cam 51, when the pressing button 52 moves towards the inner cam 2 under the action of an external force, the second elastic member 6 is compressed and generates a restoring force to drive the pressing member 5 to move away from the inner cam 2, when the external force is removed, the compressed second elastic member 6 can drive the pressing cam 51 and the pressing button 52 to move away from the inner cam 2 until it returns to the original state.

[0034] By arranging the second elastic member 6, the pressing cam 51 and the pressing button 52 can be automatically returned to the original position, the recovery of the pressing member 5 can be realized without the assistance of external force, the operation is convenient, the abutment of the pressing cam 51 and the pressing button 52 can be ensured, the virtual position between the pressing cam 51 and the pressing button 52 is eliminated, and the gap between them is avoided, so that the abnormal sound of movement is avoided.

[0035] In order to avoid the disengagement of the pressing button 52 and the outer cam 3, a limiting block 10 is arranged on the side wall of the end of the pressing button 52, the limiting block 10 is arranged to be elastic, a limiting groove 9 is arranged on the inner wall of the sliding groove 7 and extends along the sliding direction of the pressing button 52, the limiting block 10 is located in the limiting groove 9 and slides along the length direction of the limiting groove 9, due to the arrangement of the limiting groove 9 and the limiting block 10, the stroke of the pressing button 52 is restricted, the pressing button 52 is prevented from being slid out of the sliding groove 7 by the second elastic member 6, and the pressing button 52 can only move in the direction close to or away from the outer cam 3.

[0036] As another embodiment, referring to Figure 2 、 3 and Figure 8 , a shaft core 11 is further arranged and extends along the arrangement direction of the outer cam 3 and the inner cam 2, the shaft core 11 sequentially penetrates the pressing button 52, the head portion 511, the outer cam 3, the inner cam 2 and the shell 1, and the two ends of the shaft core 11 are rotationally connected to the shell 1 and the outer cam 3 respectively, so that the shaft is integrally connected and penetrates to form a whole.

[0037] A limiting block 12 is arranged on the end of the shaft core 11 towards the outer cam 3, the limiting block 12 is located in the sliding groove 7 of the outer cam 3 and abuts against the groove bottom of the sliding groove 7, the other end side wall extends out of the shell 1, a limiting groove 13 is arranged on the side wall of the other end side wall, the limiting groove 13 is located outside the shell 1, a snap ring 14 is arranged in the limiting groove 13, the snap ring 14 abuts against the outer wall of the shell 1, so that the distance between the shell 1 and the outer cam 3 is constant, the outer cam 3 is prevented from moving along the axial direction, and the first engagement surface 17 and the second engagement surface 18 are always engaged.

[0038] The shaft core 11 is sleeved with a wear-resistant sheet 15, which is located between the snap ring 14 and the outer wall of the shell 1, and is in contact with the outer wall of the shell 1 and the snap ring 14. By arranging the wear-resistant sheet 15, the friction between the snap ring 14 and the outer wall of the shell 1 is avoided, so that the shell 1 is not worn. Further, at least two protrusions 16 are arranged on the outer wall of the shell 1, and the protrusions 16 are located at the wear-resistant sheet 15 and pass through the wear-resistant sheet 15. At this time, the arrangement of the protrusions 16 makes the wear-resistant sheet 15 unable to rotate on the shell 1, so as to further avoid the friction between the wear-resistant sheet 15 and the outer wall of the shell 1, thereby preventing the shell 1 from being worn.

[0039] During installation, first, the second elastic member 6 is installed into the pressing cam 51 and assembled into the outer cam 3, so that the operation part 512 extends into the sliding hole 8, and then the pressing button 52 is inserted into the sliding groove 7. At this time, the limiting block 10 and the limiting member are in contact. The shaft core 11 is taken out, and the shaft core 11 passes through the pressing button 52, the pressing cam 51 and the outer cam 3 in sequence, so that the limiting block 12 at the end of the shaft core 11 is in contact with the groove bottom wall of the sliding groove 7, and the rotor body is formed. In addition, the first elastic member 4 is placed into the shell, and then the inner cam 2 is placed, so as to form the stator body. The above rotor body is installed on the stator body, the shaft core 11 passes through the outer cam 3 and the outer wall of the shell 1 in sequence, the limiting groove 13 extends out of the shell 1, the snap ring 14 is taken out and clamped into the limiting groove 13 and in contact with the outer wall of the shell 1, and the second meshing surface 18 of the inner cam 2 is in mesh with the first meshing surface 17 of the outer cam 3, so as to complete the assembly.

[0040] Example 2 Referring to Figures 1-8 The present embodiment provides a flip device, which comprises the automatic pop-up rotating shaft with a button in example 1, a shell and a rotatable flip. The shell 1 is installed on the shell, and the outer cam 3 is installed on the flip. The first meshing surface 17 of the outer cam 3 is in sliding fit with the second meshing surface 18 of the inner cam 2, so that when the outer cam 3 is manually rotated, the inner cam 2 is squeezed and moved towards the first elastic member 4. At this time, the first elastic member 4 is compressed and stored. When the first meshing surface 17 and the second meshing surface 18 reach the top point after being rotated by 180 degrees, the clamping block 21 is embedded into the clamping groove 20, so as to achieve locking, and the inner cam 2 and the outer cam 3 reach balance.

When the outer cam 3 needs to rotate, the presser 5 is manually pressed to move the presser 5 towards the clamping block 21, so that the clamping block 21 and the clamping groove 20 are disengaged. At this time, the first elastic member 4 releases the ability to drive the outer cam 3 to rotate and automatically pop open. The inner cam 2 moves towards the outer cam 3 until the first engagement surface 17 and the second engagement surface 18 are fully engaged in the initial state. Thus, the outer cam 3 is automatically rotated and automatically popped open by simply pressing. The problem of complicated and rigid operation of the traditional rotating shaft is solved.
