[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0030] The present invention provides a damping rotation structure 100. Figures 1-4 As shown, the rotation damping structure 100 includes a first structural member 110, a second structural member 120, a bolt 130, a nut 140, and a first flexible washer 150. The first structural member 110 is provided with a first opening 111. The second structural member 120 is disposed adjacent to the first structural member 110. The second structural member 120 is provided with a second opening 121 opposite the first opening 111. The bolt 130 is disposed through the first opening 111 and the second opening 121. The head of the bolt 130 is located on the side of the first opening 111 away from the second opening 121. The bolt 130 is fixedly connected to the first structural member 110 along its circumference. The nut 140 is mounted on the bolt 130 and is located on the side of the second opening 121 away from the first opening 111. The first flexible washer 150 is mounted on the bolt 130 and sandwiched between the nut 140 and the second opening 121 . The first flexible washer 150 is fixedly connected to the bolt 130 in a circumferential direction of the bolt 130 .

[0031] First, if the second structural member 120 rotates, driving the first flexible washer 150 to rotate, the first flexible washer 150 will continuously apply a rotational force to the nut 140, causing the nut 140 to loosen. To prevent this, in this embodiment, the first flexible washer 150 is fixedly connected to the bolt 130 along its circumference, and the bolt 130 is fixedly connected to the first structural member 110 along its circumference. Therefore, when the second structural member 120 rotates relative to the first structural member 110, neither the first flexible washer 150 nor the bolt 130 rotates with the second structural member 120. During this process, the first flexible washer 150 does not apply a rotational force to the nut 140, and thus the nut 140 is not easily loosened.

[0032] Secondly, during the production of the damping rotation structure 100, certain machining errors may occur, resulting in gaps between the various components. This gap increases as the second structural member 120 rotates relative to the first structural member 110, causing the nut 140 to gradually loosen. The first flexible washer 150 is provided to eliminate the negative effects of the gap through its own deformation, so it cannot be replaced with a washer made of a hard material.

[0033] In summary of the first and second aspects above, the nut 140 of this embodiment can be very firmly mounted on the bolt 130 , and the nut 140 is not easily loosened with increasing usage time, thereby effectively improving the service life of the damping rotation structure 100 and providing an excellent user experience.

[0034] refer to Figure 4-Figure 6 In a specific embodiment, an internally threaded blind hole 141 is provided on the side of the nut 140 facing the first structural member 110, and the bolt 130 is inserted into the internally threaded blind hole 141. An adjustment groove 142 is provided at the center of the side of the nut 140 facing away from the first structural member 110, and the contour of the adjustment groove 142 is different from a circle.

[0035] By implementing this embodiment, an adjusting member (not shown) can be used in conjunction with adjusting slot 142 to rotate and adjust nut 140. This allows the adjusting member to tighten nut 140 even if it becomes loose, providing an excellent user experience. Specifically, because the contour of adjusting slot 142 differs from a circular shape, inserting an adjusting member with a similar contour to adjusting slot 142 into adjusting slot 142 secures the adjusting member and nut 140 circumferentially. Rotating the adjusting member can then adjust the position of nut 140 on bolt 130.

[0036] refer to Figure 6 In a specific embodiment, the adjustment slot 142 is a hexagonal slot, and the adjustment member is a hexagonal wrench.

[0037] Optionally, the adjustment slot 142 is a cross slot, and the adjustment member is a cross screwdriver.

[0038] Optionally, the adjustment slot 142 is a slotted slot, and the adjustment member is a slotted screwdriver.

[0039] Optionally, the adjustment slot 142 is a square slot, and the adjustment member is a square wrench.

[0040] refer to Figure 1 、 Figure 6 In some embodiments, a receiving groove 122 is provided on a side of the second structural member 120 away from the first structural member 110 , the second opening 121 is provided at the bottom of the receiving groove 122 , and the nut 140 and the first soft washer 150 are provided in the receiving groove 122 .

[0041] By implementing this embodiment, the nut 140 and the first soft washer 150 are hidden in the accommodating groove 122 , so that the damping rotation structure 100 looks simpler, smaller and more beautiful, and the user has an excellent visual experience.

[0042] refer to Figure 4 、 Figure 6 In some embodiments, the bolt 130 includes a first mounting section 131 , and the first flexible washer 150 is sleeved on the first mounting section 131 . The outer contour of the first mounting section 131 is different from a circle, and the inner circle of the first flexible washer 150 is similar to the outer contour of the first mounting section 131 .

[0043] Specifically, because the outer contour of the first mounting section 131 differs from a circle, while the inner contour of the first flexible washer 150 is similar to the outer contour of the first mounting section 131, the first flexible washer 150 cannot rotate relative to the bolt 130 in the circumferential direction of the bolt 130 after being mounted on the first mounting section 131, thereby achieving a fixed connection between the first flexible washer 150 and the bolt 130 in the circumferential direction of the bolt 130. It is worth noting that while this embodiment achieves a fixed connection between the first flexible washer 150 and the bolt 130 in the circumferential direction, it does not require the addition of a separate connecting member, resulting in a relatively simple structure and reducing production and assembly costs. Furthermore, the outer contour of the first mounting section 131 can be rectangular, triangular, hexagonal, etc., as long as the first flexible washer 150 cannot rotate relative to the bolt 130 in the circumferential direction of the bolt 130 after being mounted on the first mounting section 131. This embodiment is not limited to this.

[0044] refer to Figure 4 、 Figure 6 In some embodiments, the first bolt 130 further includes a second mounting segment 132 , the outer contour of the second mounting segment 132 is different from a circle, the contour of the first through opening 111 is similar to the outer contour of the second mounting segment 132 , and the second mounting segment 132 is accommodated in the first through opening 111 .

[0045] Specifically, since the outer contour of the second mounting segment 132 is different from a circle, and the contour of the first through opening 111 is similar to the outer contour of the second mounting segment 132, after the second mounting segment 132 is accommodated in the first through opening 111, the bolt 130 cannot rotate relative to the first structural member 110 in its circumferential direction, thereby achieving a fixed connection between the bolt 130 and the first structural member 110 in its circumferential direction.

[0046] Furthermore, the outer contour of the second mounting section 132 can be rectangular, triangular, hexagonal, etc., as long as the second mounting section 132 is accommodated in the first opening 111, the bolt 130 cannot rotate relative to the first structural member 110 in its circumferential direction. This embodiment does not limit this.

[0047] It is worth mentioning that although this embodiment realizes the fixed connection between the bolt 130 and the first structural member 110 in its circumferential direction, no independent connecting member is added, so the structure is relatively simple, which is conducive to reducing production and assembly costs.

[0048] In other embodiments, strong glue is provided between the bolt 130 and the first structural member 110 so that the bolt 130 is fixedly connected to the first structural member 110 in its circumferential direction.

[0049] refer to Figure 4 、 Figure 6 In some embodiments, the rotation damping structure 100 further includes a second flexible washer 160 . The second flexible washer 160 is mounted on the bolt 130 and is sandwiched between the first structural member 110 and the second structural member 120 .

[0050] Specifically, the second flexible washer 160 can provide damping force when the first structural member 110 rotates relative to the second structural member 120. The second flexible washer 160 is flexible and can avoid hard contact between the first structural member 110 and the second structural member 120, thereby reducing wear on the first structural member 110 and the second structural member 120.

[0051] refer to Figure 4 、 Figure 6 In a specific embodiment, the second flexible gasket 160 is larger than the first flexible gasket 150. Compared to the embodiment in which the second flexible gasket 160 is equal in size to the first flexible gasket 150, the second flexible gasket 160 of this embodiment is larger in size and has stronger pressure resistance and deformation resistance.

[0052] refer to Figure 4 、 Figure 6 In some embodiments, the rotation damping structure 100 further includes a hard washer 170, which is mounted on the bolt 130 and sandwiched between the nut 140 and the first flexible washer 150. The nut 140 includes an abutting portion that contacts the hard washer 170. The abutting portion is smaller than the hard washer 170, and the size of the hard washer 170 is similar to that of the first flexible washer 150.

[0053] Specifically, because the abutment portion in this embodiment is smaller than the first flexible washer 150, directly pressing the abutment portion against the first flexible washer 150 would result in insufficient compression of portions of the first flexible washer 150 and excessive compression of other portions, negatively impacting the service life and performance of the first flexible washer 150. Therefore, in this embodiment, a hard washer 170 is added between the first flexible washer 150 and the nut 140. The hard washer 170 is of similar size to the first flexible washer 150, ensuring a sufficiently large area for compressing the first flexible washer 150.

[0054] refer to Figure 4 、 Figure 6 In some embodiments, the hard washer 170 is fixedly connected to the bolt 130 in its circumferential direction, which can lock the hard washer 170 to prevent it from rotating around the bolt 130, ensuring that the nut 140 is not easily loosened with the increase of usage time, effectively improving the service life of the damping rotation structure 100, and providing an excellent user experience.

[0055] refer to Figure 4 、 Figure 6 In a specific embodiment, the hard washer 170 is also installed on the above-mentioned first mounting section 131, and the inner circle of the hard washer 170 is similar to the outer contour of the above-mentioned first mounting section 131. Because the outer contour of the first mounting section 131 is different from a circle, after the hard washer 170 is installed on the first mounting section 131, it cannot rotate relative to the bolt 130 in the circumferential direction of the bolt 130, thereby achieving a fixed connection between the hard washer 170 and the bolt 130 in the circumferential direction.

[0056] In some embodiments, the first soft washer 150 is a nylon washer. Nylon washers have a relatively high hardness among soft washers, are resistant to high temperatures and friction, and are not prone to friction powdering. Therefore, in this embodiment, the first soft washer 150 is a nylon washer.

[0057] In some embodiments, the second soft washer 160 is a nylon washer. Nylon washers have a relatively high hardness among soft washers, are resistant to high temperatures and friction, and are not prone to friction powdering. Therefore, in this embodiment, a nylon washer is selected as the first soft washer 150.

[0058] In some embodiments, the hard washer 170 is a carbon steel washer. Carbon steel washers have the advantages of high hardness and are not easily deformed, so in this embodiment, the hard washer 170 is a carbon steel washer.

[0059] The present invention also provides an electronic product stand 1000. Figure 1 、 Figure 2 As shown, the electronic product stand 1000 includes the damping rotation structure 100 shown in the above embodiment. Since the beneficial effects have been recorded in the damping rotation structure 100 shown in the above embodiment, they will not be repeated in this embodiment.

[0060] It is worth mentioning that the electronic product stand 1000 can be an electronic product stand suitable for supporting electronic products such as mobile phones, tablet computers, and laptop computers, and this embodiment does not limit this.

[0061] refer to Figure 1 、 Figure 2In a specific embodiment, the electronic product stand 1000 further includes a base 200 and a support base 300. The first structural member 110 of the damping rotation structure 100 is a connecting ear disposed on the base 200. The second structural member 120 of the damping rotation structure 100 is a rotating arm, with a second opening 121 on one end of the rotating arm. The support base 300 is connected to the other end of the rotating arm and is used to support electronic products.

[0062] By implementing this embodiment, the rotation angle of the rotating arm can be infinitely adjusted, and even if it is used for a long time, there is no need to worry about the rotation angle of the rotating arm being unable to be locked due to the loosening of the nut 140, and the user experience is excellent.

[0063] refer to Figure 1 、 Figure 2 In a specific embodiment, the support base 300 is rotatably connected to the other end of the rotating arm, so that the user can adjust the pitch angle of the electronic product as needed, providing a better user experience. The specific implementation of the rotatable connection between the support base 300 and the other end of the rotating arm can be referred to the damping rotation structure 100 of the above embodiment, and this embodiment will not be described in detail here.

[0064] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Those skilled in the art may modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
