Technical Field
[0001] This invention relates to the field of functional integration module manufacturing technology, and more specifically to a gear adjustment structure. Background Technology
[0002] Currently, in practical operation, the market has increasingly higher requirements for the precision and stability of gear adjustment and self-resetting structures in functional integration modules. When adjusting gears, the lack of corresponding prompts during operation often leads to adjustment errors. Furthermore, existing self-resetting structures all use springs to achieve the self-resetting effect, utilizing the characteristic that a spring deforms under external force and returns to its original state after the force is removed. Although springs are relatively inexpensive, they also experience significant wear and tear. If a spring operates for too long or is used too frequently, its performance will be affected, resulting in reduced elasticity or even spring breakage. Insufficient spring elasticity significantly reduces its effectiveness, leading to problems with timely reset, and potentially causing economic losses and personal injury.

[0028] 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, and 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.
[0029] See appendix Figure 1 To be continued Figure 5 According to an embodiment of the present invention, the gear adjustment structure includes: a mounting base 1, an inner shell 2 and an outer shell 3, a central shaft 4, a plunger 5, and a hemispherical joint 6;
[0030] Mounting base 1 has an assembly cavity that extends through its upper end face; the inner shell 2 and the outer shell 3 are vertically connected, with the inner shell 2 located inside the outer shell 3 and rotatably connected by bearings; the lower part of the outer shell 3 is arranged correspondingly to the upper part of the assembly cavity; the central shaft 4 passes through the inner shell 2 to the lower part of the assembly cavity; the plunger 5 is arranged perpendicular to the central shaft 4, and a ball bearing 51 is connected to one end near the central shaft 4, while the other end is fixed to the outer wall of the corresponding outer shell 3, and the outer wall of the inner shell 2 corresponding to the ball bearing 51 is provided with circumferentially arranged hobbing teeth, and the ball bearing 51 rolls and abuts against the hobbing teeth; the hemispherical joint 6 is fixed on the central shaft 4 in the corresponding assembly cavity, and a ball cap 8 is installed on the inner wall of the assembly cavity, with the upper end of the hemispherical joint 6 spherically rollingly connected to the ball cap 8.
[0031] Specifically, the inner housing 2 is made of aluminum alloy, and its surface is subjected to micro-arc oxidation treatment to enhance its wear resistance; the outer housing 3 is a hollow cylindrical structure made of aluminum alloy; the bearing is a deep groove ball bearing 6704-2Z / P5, and the bearing is interference-fitted with the outer housing 3 and fixed to the mounting surface of the outer housing 3 by a pressure plate, which is fixedly connected to the inner housing 2 by screws; the central shaft 4 is a slender rod-shaped structure made of aluminum alloy; the hemispherical joint 6 is a spherical structure made of brass; the ball cap 8 is a semi-circular ring structure made of aluminum alloy; and the plunger 5 is purchased from MISUMI BPQ4.
[0032] In this invention, the outer surface of the inner housing features a gear-hobbed structure to provide a mechanical feel for gear adjustment in conjunction with the ball bearings of the plunger. The inner housing and outer housing are connected by bearings, which support the rotation of the outer housing, reduce the coefficient of friction during rotation, and ensure the rotational accuracy of the outer housing. Both sides of the bearings have iron dust covers to prevent dust, iron filings, and other debris from entering the bearings and adhering to the ball bearings or ball bearing tracks, thus affecting bearing life. This facilitates the rotation of the outer housing, thereby enabling gear adjustment. The central shaft is fixedly connected to a hemispherical joint to achieve forward, backward, left, and right rotation. This invention provides a gear-adjustable structure where the operator can achieve a mechanical feel for gear shifting by engaging the ball bearings with the gears of the inner housing during gear adjustment, thus ensuring accurate gear shifting.
[0033] In some specific embodiments, the plunger may further include a plunger assembly ring 11, which corresponds to the position of the plunger 5 and is located at the lower part between the inner housing 2 and the outer housing 3 and is fixed to the inner wall surface of the outer housing 3; the plunger assembly ring 11 and the corresponding outer housing have radially through assembly holes, and the plunger 5 is located in the assembly holes.
[0034] Specifically, the plunger assembly pressure ring 11 can be a hollow cylindrical structure made of aluminum alloy; the plunger assembly pressure ring 11 is fixedly connected to the outer wall of the outer shell 3 by bolts. Thus, by setting the plunger assembly pressure ring, the connection and cooperation between the plunger and the outer shell and inner shell can be realized, providing space for the plunger's ball bearings to be assembled, and further realizing the mechanical feel effect produced by gear adjustment.
[0035] In some specific embodiments, the mounting base 1 may also include a base plate 101 and a transition ring seat 102, a cover plate ring seat 103 and a decorative ring 104 arranged coaxially. The transition ring seat 102 is fixed on the base plate 103, the cover plate ring seat 103 is fixed on the transition ring seat 102, and the lower end of the decorative ring 104 is fixed on the cover plate ring seat 103.
[0036] Specifically, the base plate 101 can be a thin plate structure made of aluminum alloy; the transition ring seat 102 is a cuboid structure with a circular hole in the middle; the cover ring seat 103 is a cylindrical structure; and the decorative ring 104 is a hollow cylindrical structure made of aluminum alloy with a black anodized surface. Thus, the mutual fixing and connection of the various components of the mounting base provides space for the self-resetting structure. At the same time, the fixing of the mounting base ensures the rotation of the central shaft, inner shell, and outer shell; it also further ensures the mutual cooperation between the various components and better adapts to specific functional integration modules, thereby better fulfilling its function.
[0037] In some specific embodiments, the gear adjustment structure of the present invention further includes a self-resetting structure 7. The self-resetting structure 7 includes a first magnetic attraction structure 71 and a second magnetic attraction structure 72 arranged opposite to each other and capable of being attracted. The first magnetic attraction structure 71 is mounted on the lower end of the central shaft 4, and the second magnetic attraction structure 72 is mounted on the base plate 101 below the corresponding first magnetic attraction structure 71 with a gap at the attraction end. For example, the N pole of the first magnetic attraction structure 71 is opposite to the S pole of the second magnetic attraction structure 72 to generate a strong attraction. Thus, the present invention utilizes the mutual attraction between the first magnetic attraction structure and the second magnetic attraction structure to enable the shell in different states to return to the initial position, achieving self-resetting and zeroing effect. This enhances the safety of the corresponding module during actual operation. The specific operation is as follows: When the inner housing is moved by hand, the inner housing, central shaft, hemispherical joint, mounting sleeve, and first magnetic attraction structure are mechanically connected as a whole. This entire unit will rotate around the center line of the hemispherical joint, while the mounting base and the second magnetic attraction structure remain stationary. Therefore, the first magnetic attraction structure will move away from the second magnetic attraction structure. When the hand leaves the inner housing, the second magnetic attraction structure will drive the first magnetic attraction structure and the inner housing back to their original positions, achieving a zeroing effect. Simultaneously, utilizing the attraction between magnets to achieve a self-resetting effect can extend the service life of the component and ensure its superior performance.
[0038] In some specific embodiments, the first magnetic attraction structure 71 includes a magnet 711 and a mounting sleeve 712, the mounting sleeve 712 is fixedly connected to the lower end of the central shaft 4, and the magnet 711 is fixedly connected to the mounting sleeve 722. The second magnetic attraction structure 72 includes a magnet 21 and a mounting sleeve 722, the mounting sleeve 722 is fixedly connected to the base plate 101, and the magnet 21 is fixedly connected to the mounting sleeve 722.
[0039] In some specific embodiments, both mounting sleeve 712 and mounting sleeve 722 can be made of aluminum alloy, and both magnet 711 and magnet 721 are cylindrical magnets with countersunk holes. Therefore, the countersunk holes facilitate further fixing of the magnets, and the mounting sleeves further restrict and reinforce the magnets, enabling them to function and achieve their effects more stably.
[0040] In some specific examples, a joint support seat 10 may also be included, which has a spherical support cavity. The outer wall of the joint support seat 10 is fixed to the inner wall of the decorative ring 104. The hemispherical joint 6 is located in the spherical support cavity of the joint support seat and is radially fixed to the central axis 4 by a pin 9. The two ends of the pin can be snapped onto the joint support seat.
[0041] Specifically, pin 9 has a specification of 2m6×20 (GB / T119.1); the joint support 10 can be a cylindrical structure with a spherical cavity in the middle, which cooperates with the hemispherical joint 6 to form a ball joint, and the material is 316L stainless steel. Thus, the ball joint formed by the cooperation of the joint support and the hemispherical joint achieves the technical effect of the shell driving the central shaft to rotate back and forth and left and right.
[0042] In some specific embodiments, a pressure plate 13 may also be included, with the inner shell 2 fixedly connected to the pressure plate 13.
[0043] Specifically, the pressure plate 13 can be a circular ring structure made of aluminum alloy. This allows for further facilitating the connection between the inner and outer housings of the bearing by using the pressure plate.
[0044] In other embodiments, the bearing 12 is interference-fitted with the housing 3 and fixed to the inner surface of the housing 3 by a pressure plate 13. This further improves the stability of the bearing and ensures that the bearing can effectively connect the inner housing and the outer housing.
[0045] Specifically, the ball cap 8 and the joint support 10 are both fixedly connected to the inner wall of the decorative ring 4. Thus, by fixing the ball cap and the joint support inside the decorative ring, the ball cap, the joint support, and the hemispherical joint can be further matched to each other, ensuring the stability of their matching.
[0046] The working principle of the gear adjustment structure provided in this embodiment is as follows:
[0047] According to the embodiments of the invention, the overall structure of the gear adjustment structure is divided into moving parts and non-moving parts. The moving parts include the outer shell, the plunger assembly pressure ring, and the plunger, which have a rotating motion relative to the central axis; the inner shell, the outer shell, the central shaft, the pin, the hemispherical joint, the mounting sleeve one, and the magnet one have a swinging motion around the central axis. The non-moving parts, namely the decorative ring, the ball cover, the joint support seat, the cover plate ring seat, the transition ring seat, the base plate, the mounting sleeve two, and the magnet two, are stationary.
[0048] When adjusting the gear, rotating the outer casing causes relative movement between the plunger and the inner casing. As a result, the plunger's balls will make circular motion on the hobbing teeth on the outer side of the inner casing, creating the "gear shifting" mechanical feel.
[0049] When the self-reset command is executed, the moving parts rotate around the horizontal line where the pin is located when the inner housing is moved by hand, thus achieving the self-reset effect. Specifically, through the mutual attraction and cooperation of the first and second magnetic structures, when the operator stops operating and removes their hand from the inner housing, the central axis can be kept upright again, ensuring that the module command returns to its initial value.
[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
