[0030] The utility model discloses a rotating shaft structure and an electronic device, which are used to solve the technical problem that a large number of friction plates need to be added to the rotating shaft structure of the prior art to stop and maintain the rotating part at any angle, thereby resulting in a complex structure and high manufacturing cost.

[0031] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 5 , a rotating shaft structure provided by an embodiment of the utility model includes a fixing member 3 and a rotating member 4;

[0033] The fixing member 3 is provided with an annular protrusion 8, the middle part of which is provided with an axis 7 protruding from the fixing member 3, the inner side wall of the annular protrusion 8 is provided with a circle of toothed portions 5, and tooth grooves 6 are formed between two adjacent toothed portions 5;

[0034] The middle part of the rotating member 4 is provided with an axial hole 9 which is rotatably matched with the shaft center 7. The axial hole 9 is rotatably connected to the shaft center 7. A stopper 10 is elastically connected to the outer side of the axial hole 9. The end of the stopper 10 away from the axial hole 9 is a pointed end 1001, and the pointed end 1001 is meshed with the tooth groove 6.

[0035] When the rotating member 4 is driven to rotate relative to the fixed member 3, the locking portion 10 overcomes the elastic force so that its pointed end 1001 passes through multiple tooth grooves 6 in sequence until the rotating member 4 stops rotating. At this time, the pointed end 1001 of the locking portion 10 is engaged in the tooth groove 6 to limit the rotation of the rotating member 4 relative to the fixed member 3.

[0036] Through the above design, the function of the rotating part 4 rotating and stopping relative to the fixed part 3, stopping and maintaining at any angle can be effectively realized without the need for a friction plate. In addition, the shaft structure is simpler, the assembly difficulty is low, and it is more conducive to controlling production costs.

[0037] In addition, during the rotation of the rotating part 4 relative to the fixed part 3, under the action of elastic force, the pointed end 1001 of the locking part 10 will continuously collide with the tooth pattern part 5 when passing through each tooth groove 6, thereby generating a sound effect similar to that of metal mechanical transmission, which is beneficial to increasing the user's auditory experience.

[0038] Furthermore, in this embodiment, an elastic member is connected to the outer side of the shaft hole 9 , and one end of the elastic member away from the shaft hole 9 is connected to the locking portion 10 .

[0039] It should be noted that the elastic member in this embodiment tends to move the pointed end 1001 of the locking portion 10 toward the tooth groove 6. When the rotating member 4 rotates relative to the fixed member 3 and the pointed end 1001 moves from one tooth groove 6 to another tooth groove 6, the pointed end 1001 will interfere with the tooth groove portion 5 and compress the elastic member. When the pointed end 1001 is engaged with the other tooth groove 6, the elastic member recovers and drives the pointed end 1001 to tightly engage with the locking groove.

[0040] Furthermore, a mounting hole is formed at one end of the locking portion 10 in this embodiment close to the shaft hole 9 , and one end of the elastic member away from the shaft hole 9 is connected to the mounting hole.

[0041] It should be noted that, through the above design, the mounting hole can limit the elastic member to deform only along a preset direction, thereby ensuring the movement stability of the locking portion 10 .

[0042] Specifically, the elastic member in this embodiment is preferably a spring or a spring sheet, wherein the spring sheet can be a spring sheet made of a metal material or a spring sheet made of a silicone material. This embodiment does not limit the specific type of the elastic member.

[0043] Furthermore, a guide slot 11 is provided on the rotating member 4 in this embodiment at a position close to the shaft hole 9;

[0044] The locking portion 10 is slidably connected to the guide slot 11 .

[0045] It should be noted that, through the above design, the stopper 10 can only move along the guide slot 11, which ensures the single movement direction of the stopper 10 and makes the stopper 10 move more steadily and smoothly.

[0046] Furthermore, a foam layer 12 laid on the fixing member 3 is also provided on the periphery of the axis 7 in this embodiment;

[0047] The surface of the foam layer 12 away from the fixing member 3 is in contact with the rotating member 4 .

[0048] It should be noted that, through the above design, the foam layer 12 can fill the gap between the rotating part 4 and the fixed part 3, making the shaft structure more compact, and the foam layer 12 can act as a buffer structure between the rotating part 4 and the fixed part 3, changing the hard contact between the rotating part 4 and the fixed part 3 into a flexible contact, thereby making the rotating part 4 feel better when rotating.

[0049] Furthermore, a grease layer is coated inside the tooth groove 6 in this embodiment.

[0050] It should be noted that, through the above design, the grease layer can make the pointed end 1001 of the locking portion 10 pass through each tooth groove 6 more smoothly, thereby avoiding the situation where a jam occurs and the rotating member 4 is difficult to rotate.

[0051] See also Figures 1 to 5 An electronic device provided by an embodiment of the utility model includes the above-mentioned rotating shaft structure.

[0052] Specifically, the electronic device includes a housing 1 and a rotating handle 2;

[0053] The rotating handle 2 is rotatably connected to the housing 1 via the rotating shaft structure.

[0054] The fixing member 3 of the rotating shaft structure is fixed on the housing 1 , and the rotating member 4 of the rotating shaft structure is fixed on the rotating handle 2 .

[0055] Through the above design, the function of rotating the handle 2 relative to the shell 1 and stopping at any angle can be effectively achieved without the need for a friction plate. In addition, the above-mentioned shaft structure is simpler, the assembly difficulty is low, and it is more conducive to controlling production costs.

[0056] The above is a detailed introduction to a shaft structure and an electronic device provided by the present invention. For a person skilled in the art, according to the idea of ​​the embodiments of the present invention, there may be changes in the specific implementation method and the scope of application. In summary, the content of this specification should not be understood as a limitation on the present invention.
