[0034] Combine the following Figures 1 to 12 The knob 100 and the electronic device 200 according to the embodiment of the present application are described.

[0035] First, as Figures 1 to 6 As shown, an embodiment of the present application provides a knob 100, comprising: a seat body 110, the seat body 110 comprising a first slide groove 112, and the first slide groove 112 is spiral; a cover body 130, which is rotatable relative to the seat body 110, and the cover body 130 comprises a second slide groove 132; a slide rod 140, the slide rod 140 comprises a first sliding portion 142 and a second sliding portion 144, the first sliding portion 142 extends into the first slide groove 112, and the second sliding portion 144 extends into the second slide groove 132; wherein, when the cover body 130 rotates relative to the seat body 110, the first sliding portion 142 performs a spiral motion along the first slide groove 112, and the second sliding portion 144 moves along the second slide groove 132.

[0036] In the embodiment of the present application, the knob 100 includes a base body 110, a cover body 130 and a sliding rod 140. The base body 110 includes a first sliding groove 112, the cover body 130 includes a second sliding groove 132, and the sliding rod 140 includes a first sliding portion 142 and a second sliding portion 144. The first sliding portion 142 extends into the first sliding groove 112 and cooperates with the first sliding groove 112. The second sliding portion 144 extends into the second sliding groove 132 and cooperates with the second sliding groove 132.

[0037] Among them, the guiding trajectory of the first slide groove 112 is spiral, and when the cover body 130 rotates relative to the base body 110, the first sliding part 142 can perform a spiral motion along the first slide groove 112, and as the first sliding part 142 rotates, the second sliding part 144 adapts to the position of the first sliding part 142 and slides along the second slide groove 132, so that the cover body 130 can rotate more than one circle relative to the base body 110, that is, the rotation angle of the cover body 130 relative to the base body 110 can be greater than 360°, thereby increasing the rotation stroke of the knob 100. When a larger rotation angle is required, there is no need to stack multiple knobs 100.

[0038] As mentioned above, the slide rod 140 rotates synchronously when the cover body 130 is rotated by external force. Since the first sliding part 142 is limited to the first slide groove 112, the slide rod 140 will move according to the spiral guide trajectory limited by the first slide groove 112, and the second slide groove 132 is linear or arc-shaped, etc., so that the slide rod 140 also moves linearly or arc-shaped relative to the cover body 130. The limit number of turns of the entire rotation process is the number of spiral turns of the first slide groove 112, and the starting and ending positions are the starting and ending positions of the first slide groove 112.

[0039] The present application adopts the guide track restriction of the slide rod 140 in the first slide groove 112, so that it can rotate multiple times on a single-layer structure, thereby saving space in the thickness direction. If the number of turns needs to be increased, it is only necessary to add a transverse design to the first slide groove 112. At the same time, it also saves the number of structural parts compared to the conventional design of adding one more structural part for each additional turn, which can improve the frustration of the cover body 130 during the adjustment process and realize multi-turn stepless adjustment. The second slide groove 132 also limits the moving direction of the second sliding part 144, so that the slide rod 140 can only move in one direction, thereby achieving the purpose of synchronous rotation of the cover body 130 and the slide rod 140.

[0040] Specifically, when the cover body 130 rotates relative to the base body 110, the slide rod 140, under the restriction of the second slide groove 132, realizes synchronous rotation with the cover body 130, and the slide rod 140, under the guidance of the first slide groove 112, performs spiral rotation, so that the position of the slide rod 140 changes. Due to the restriction of the second slide groove 132, the slide rod 140 moves along the second slide groove 132.

[0041] As described above, the movement direction of the slide bar 140 is limited by the slide groove, so that the slide bar 140 slides in the first slide groove 112 and the second slide groove 132, thereby making the movement of the slide bar 140 smoother and improving the reliability of guiding the slide bar 140.

[0042] The second slide groove 132 is arranged on the cover body 130, and the second sliding portion 144 of the slide rod 140 can be movably arranged in the second slide groove 132 to realize the limitation of the second direction of the slide rod 140. In the first direction, the slide rod 140 has a linear movable space, and the second sliding portion 144 has a first sliding portion 142 on the side facing the seat body 110, and the first sliding portion 142 is inserted into the first slide groove 112.

[0043] As mentioned above, the slide rod 140 rotates synchronously when the cover body 130 is rotated by external force. Since the first sliding part 142 is restricted by the first slide groove 112, the slide rod 140 will rotate in the first slide groove 112, and the second sliding part 144 is restricted by the second slide groove 132, and the slide rod 140 will move linearly in the second slide groove 132, thereby realizing the rotation of the base body 110 relative to the cover body 130. The limit number of turns of the entire rotation process is the number of turns of the first slide groove 112, and the starting and ending positions are the starting and ending positions of the first slide groove 112.

[0044] As a possible implementation, Fig. 9 As shown, the first sliding portion 142 and the second sliding portion 144 are an integrated structure; or as Fig.10 As shown, the first sliding portion 142 is fixed to the second sliding portion 144; or Fig.11 As shown, the first sliding portion 142 is rotatably disposed on the second sliding portion 144 .

[0045] Specifically, Fig. 9 As shown, the first sliding portion 142 and the second sliding portion 144 are an integrated structure, thereby reducing the production steps of the sliding rod 140, and the sliding rod 140 is formed in one step by injection molding or turning.

[0046] Or Fig.10 As shown, the first sliding part 142 is fixed to the second sliding part 144, so that the first sliding part 142 and the second sliding part 144 can be made of different materials. Since the rotation path of the first sliding part 142 is long, the first sliding part 142 is made of a material with better wear resistance, and then the first sliding part 142 is installed on the second sliding part 144, thereby reducing the production cost. In addition, when repairing or replacing, the first sliding part 142 or the second sliding part 144 can also be repaired or replaced separately, reducing the repair cost. The first sliding part 142 can be fixed to the second sliding part 144 by screws, rivets or buckles.

[0047] Or Fig.11 As shown, the first sliding part 142 is rotatably arranged on the second sliding part 144, that is, the first sliding part 142 is arranged on the second sliding part 144 in the state of a ball, so that when the first sliding part 142 rotates along the guide track of the first slide groove 112, the first sliding part 142 can rotate relative to the second sliding part 144, so that the sliding friction between the first sliding part 142 and the first slide groove 112 is adjusted to rolling friction, thereby reducing the wear of the first sliding part 142 and the first slide groove 112, and improving the service life of the knob 100.

[0048] Specifically, a hemispherical hole may be provided on the second sliding part 144 , and the first sliding part 142 may be placed into the hole to achieve rotation of the first sliding part 142 relative to the second sliding part 144 .

[0049] As mentioned above, the first sliding portion 142 is not limited to an integrated type, but can also be detachable and use a ball-star steel ball embedded structure to reduce the friction during the movement of the sliding rod 140, improve abnormal noise and increase life.

[0050] A lubricant may be arranged in the first sliding groove 112 to improve the smoothness of sliding of the first sliding portion 142 in the first sliding groove 112 .

[0051] like Figure 7 As shown, as a possible implementation, along the first direction AB, a first distance L2 between one end of the first sliding portion 142 and the second sliding portion 144 is smaller than a second distance L3 between the other ends of the first sliding portion 142 and the second sliding portion 144; wherein the first direction AB is the movable direction of the second sliding portion 144.

[0052] Specifically, along the first direction AB, that is, the moving direction of the second sliding part 144, the first distance L2 between one end of the first sliding part 142 and the second sliding part 144 is smaller than the second distance L3 between the other ends of the first sliding part 142 and the second sliding part 144. Furthermore, when the sliding rod 140 follows the cover body 130 to rotate to the outermost circle, one end of the second sliding part 144 is close to the first sliding part 142 outward, thereby reducing the moving space required for the sliding rod 140, which helps to reduce the volume of the knob 100.

[0053] Furthermore, the above configuration enables the second sliding portion 144 to have a certain length, so that the second sliding portion 144 can move more stably in the second sliding groove 132 , thereby improving the stability of the movement of the sliding rod 140 .

[0054] The first sliding portion 142 may be substantially located at the end of the second sliding portion 144 to minimize the space required for the sliding rod 140 to rotate.

[0055] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, as a possible embodiment, the cover body 130 includes: a cover body 134, the cover body 134 has a receiving groove 136; a protrusion 138, which is arranged on the cover body 134 and is located in the receiving groove 136, and a second slide groove 132 is formed on the protrusion 138; wherein the seat body 110 closes the receiving groove 136, and the second slide groove 132 is opposite to the seat body 110.

[0056] Specifically, the cover body 130 includes a cover body 134 and a protrusion 138, the protrusion 138 is arranged on the cover body 134, the cover body 134 has a receiving groove 136, the protrusion 138 is located inside the receiving groove 136, and the second slide groove 132 is arranged on the protrusion 138. The base 110 can close the receiving groove 136 and close the sliding rod 140 inside, so that the first slide groove 112, the second slide groove 132 and the sliding rod 140 are all protected by the base 110 and the cover body 130, thereby reducing the possibility of rotational damage.

[0057] The receiving groove 136 may be a cylindrical structure, and the cover body 134 may also be a cylindrical structure.

[0058] Specifically, the number of the protrusions 138 is at least two, and the protrusions 138 are arranged on the cover body 134 at intervals, so that a second sliding groove 132 is formed between at least two protrusions 138 .

[0059] like Figure 4As shown, the protrusion 138 clamps the second sliding portion 144, that is, the span of the second sliding groove 132 is slightly larger than the width of the second sliding portion 144, thereby ensuring that the second sliding portion 144 can slide along the first direction AB in the second sliding groove 132 without rotating at a large angle.

[0060] The edge of the cover body 134 has a convex edge to provide a limit for the second wearable portion to prevent the second wearable portion from being wrapped around the outside of the cover body 134.

[0061] As a possible implementation, the cover body 134 and the protrusion 138 are an integrated structure.

[0062] Specifically, the cover body 134 and the protrusion 138 are an integrated structure, thereby improving the strength of the cover 130, so that the cover 130 can be integrally manufactured by injection molding or the like, thereby reducing the processing cost of the cover 130. The cover body 134 and the protrusion 138 can be made of plastic or metal.

[0063] like Figure 2 As shown, as a possible implementation, along the first direction AB, there is a gap L1 between the protrusion 138 and the cover body 134 ; wherein the first direction AB is the movable direction of the second sliding portion 144 .

[0064] Specifically, along the first direction AB, that is, the moving direction of the second sliding portion 144, there is a gap L1 between the protrusion 138 and the cover body 134, so that the sliding rod 140 can extend out of the protrusion 138, and the volume of the protrusion 138 can be reduced, the cost can be reduced, and the friction between the sliding rod 140 and the protrusion 138 can be reduced, the wear between the sliding rod 140 and the protrusion 138 can be reduced, and the service life of the knob 100 can be improved.

[0065] Along the first direction AB, there are gaps L1 between both ends of the protrusion 138 and the groove wall of the receiving groove 136 of the cover body 134 .

[0066] like Figure 1 , Figure 3 , Figure 6 and Figure 8 As shown, as a possible embodiment, the seat body 110 includes: a base 114; a seat body 118, which is arranged on the base 114, and the first slide groove 112 is arranged on the seat body 118, the seat body 118 is located on one side of the cover body 130, and the seat body 118 and the slide rod 140 are located between the base 114 and the cover body 130.

[0067] Specifically, the seat body 110 includes a base 114 and a seat body 118, the first slide groove 112 is arranged on the seat body 118, the seat body 118 is located on one side of the cover body 130, the first slide groove 112 and the slide rod 140 are located between the base 114 and the cover body 130, so that the slide rod 140 and the seat body 118 are protected by the base 114 and the cover body 130, thereby reducing the possibility of rotational damage.

[0068] The seat body 118 may be a round cake-shaped structure, and the base 114 may be a round cake-shaped structure.

[0069] like Figure 1 and Figure 6 As shown, as a possible implementation, the seat body 118 is fixed to the base 114 by a fixing member 150; wherein a first positioning portion 116 is provided on the base 114, and a second positioning portion 120 is provided on the seat body 118, and the first positioning portion 116 and the second positioning portion 120 cooperate with each other.

[0070] Specifically, the seat body 118 is fixed to the base 114 by the fixing member 150, so that the base 114 and the seat body 118 can be made of different materials. Since the first slide groove 112 and the slide rod 140 rub against each other, the seat body 118 can be made of a material with better wear resistance, while the base 114 does not need to be made of a material with better wear resistance, thereby reducing the production cost of the knob 100.

[0071] The fixing member 150 may be a screw, a rivet or a clip, etc. The seat body 118 is fixed to the base 114 by means of screws, rivets or clips. Of course, in other embodiments of the present application, the seat body 118 and the base 114 may also be made into an integrated structure, which can be determined based on actual conditions.

[0072] Among them, one of the first positioning portion 116 and the second positioning portion 120 is a protrusion, and the other is a groove. The protrusion is embedded in the groove, so as to achieve synchronous rotation of the seat body 118 and the base 114.

[0073] As a possible implementation, the portion of the seat body 110 corresponding to the first slide groove 112 is made of plastic material, or the portion of the seat body 110 corresponding to the first slide groove 112 is made of metal material, and a first coating 122 is provided on the first slide groove 112; the slide rod 140 is made of metal material.

[0074] Specifically, the portion of the seat body 110 corresponding to the first slide groove 112 is made of plastic material, thereby ensuring the wear resistance of the first slide groove 112, and the slide rod 140 is made of metal material. Through the above materials, both cost and wear resistance are taken into consideration.

[0075] That is, the seat body 118 can be made of plastic.

[0076] Or, if Figure 8 As shown, the portion of the seat body 110 corresponding to the first slide groove 112 is made of metal, and the first slide groove 112 has a first coating 122 to ensure the wear resistance of the first slide groove 112, and the slide rod 140 is made of metal. Through the above materials, both cost and wear resistance are taken into account.

[0077] That is, the seat body 118 may be made of metal and coated with the first coating 122 .

[0078] Among them, the part of the seat body 110 corresponding to the first slide groove 112 can be made of self-lubricating and wear-resistant materials such as polyformaldehyde resin (POM), or the part of the seat body 110 corresponding to the first slide groove 112 can be made of materials such as metal material spray-lubricated wear-resistant coating, thereby improving the wear resistance and service life of the first slide groove 112.

[0079] That is, the seat body 118 can be made of self-lubricating and wear-resistant materials such as polyoxymethylene resin, or the seat body 118 can be made of metal materials sprayed with lubricating and wear-resistant coatings.

[0080] The slide bar 140 is made of metal material to ensure the strength and service life of the slide bar 140 .

[0081] like Fig.12 As shown, in the second aspect, an embodiment of the present application provides an electronic device 200, comprising: a first wearable portion 210 and a second wearable portion 220; and a knob 100 as provided in the embodiment of the first aspect, wherein the base 110 of the knob 100 is connected to the first wearable portion 210, and the cover 130 of the knob 100 is connected to the second wearable portion 220; wherein, when the cover 130 rotates relative to the base 110, at least one of the first wearable portion 210 and the second wearable portion 220 is wound around or loosened on the knob 100.

When the cover 130 rotates in one direction relative to the base 110, the second wearable portion 220 can be gradually wound on the cover 130, thereby reducing the space enclosed by the first wearable portion 210 and the second wearable portion 220. When the cover 130 rotates in another direction relative to the base 110, the second wearable portion 220 can be gradually loosened on the cover 130, thereby increasing the space enclosed by the first wearable portion 210 and the second wearable portion 220, thereby achieving the purpose of adjusting the tightness of the electronic device 200 when worn.
