Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-11 This utility model discloses a mobile phone and tablet stand, including a stand body 1. The stand body 1 includes a base assembly 2 and an adjustment arm 3 disposed thereon. The end of the adjustment arm 3 away from the base assembly 2 is provided with a universal ball joint 4.

[0033] The adjusting arm 3 includes a swing arm 31 and a swing arm 32 connected by a damping component 5. The swing arm 31 is connected to the base component 2 by a damping component 7. The swing arm 31 and the swing arm 32 are formed by hard extrusion of aluminum profile and aluminum die casting.

[0034] Both the damping component 5 and the damping component 7 are equipped with an oil storage damping mechanism 6. The oil storage damping mechanism 6 includes a copper sheet 61 and an iron sheet 62, and the iron sheet 62 is provided with an oil storage structure.

[0035] Specifically, the damping assembly 5 includes a rotating head 51 and a rotating head 52. The rotating head 51 is located at one end of the swing arm 31, and the rotating head 52 is located at one end of the swing arm 32. The rotating head 51 and the rotating head 52 are connected by an oil storage damping mechanism 6. The rotating head 52 has a copper plate 61 and an iron plate 62 inside. The iron plate 62 has several oil storage grooves 63 on the side facing the copper plate 61. The oil storage damping mechanism 6 also includes a limiting component 64, a limiting ring 65, a wave-shaped washer 66, a round washer 67, a pressure block nut 68, and a locking screw 69.

[0036] In this embodiment, the surface of the iron sheet 62 has an oil storage hole, and the damping attenuation is minimal when oil is present. The two ends of the iron sheet 62 are bent and snapped into the outside of the limiting member 64, so that when the limiting member 64 rotates, it drives the iron sheet 62 to rotate. The outer edge of the copper sheet 61 is provided with three slots that are locked inside the rotating head 52. When the iron sheet 62 rotates, the friction with it will not drive the copper sheet 61 to rotate.

[0037] Specifically, the rotating head 2 52 is provided with a limiting member 64 inside, and the rotating head 1 51 is provided with a limiting ring 65 inside. One end of the limiting member 64 passes through the iron sheet 1 62 and the copper sheet 1 61 in sequence and extends into the interior of the limiting ring 65. Both the limiting member 64 and the limiting ring 65 are provided with matching tooth structures.

[0038] Specifically, a wave-shaped washer 66 is provided on one side of the limiting ring 65 and inside the limiting member 64. A circular washer 67, located on one side of the wave-shaped washer 66 and not less than one, is also provided on one side of the limiting ring 65. A pressure block nut 68, located on one side of the wave-shaped washer 66, is provided inside the limiting member 64. One end of the rotating head 52 is nested inside one end of the rotating head 51. A locking screw 69, one end of which passes through the circular washer 67 and the limiting member 64 and is screwed into the pressure block nut 68, is provided inside the rotating head 51.

[0039] In this embodiment, end caps 53 are fitted onto the opposite ends of rotating head 51 and rotating head 52. A sealing ring 54 is fitted onto the outside of the end cap 53. After the locking screw is connected to and tightened with the pressure block nut 68, the wave-shaped gasket 66 provides good resilience and continuously resists the pressure block nut 68, preventing the damping from loosening. When rotating the swing arm 32 to adjust its relative angle with the swing arm 31, the swing arm 32 drives the copper plate 61 to rotate relative to the iron plate 62 through the rotating head 52, thereby achieving angle adjustment. A gasket can also be added between the rotating head 52 and the rotating head 51 to further increase the rotational resistance and improve the stability after angle adjustment.

[0040] Specifically, the base assembly 2 includes a support tube 21 and a clamping seat 22. A rubber pad 23 is provided on the top of the inner wall of the clamping seat 22. A base 24 is provided at one end of the support tube 21. A boss 25 is provided at the bottom of the base 24, and the bottom end of the boss 25 extends into the interior of the rubber pad 23 and is fixed with a fixing piece 26 by screws. A wire clip 33 is provided on both the first swing arm 31 and the second swing arm 32.

[0041] Specifically, stainless steel gaskets 27 are provided on the top of the fixing plate 26 and the bottom of the base 24 at the position outside the boss 25. The base 24 and the fixing plate 26 are respectively in contact with the clamping seat 22 through the stainless steel gaskets 27. A connecting plate 28 is fixedly provided inside the clamping seat 22. An adjusting screw 29 coaxially opposite to the support tube 21 is threaded inside the connecting plate 28. A clamping plate 291 is provided at the top of the adjusting screw 29 and a handle 292 is provided at the bottom of the adjusting screw 29.

[0042] In this embodiment, the top of the fixing plate 26 extends into the interior of the boss 25 so that the fixing plate 26 and the boss 25 rotate synchronously. By rotating the base 24 and the support tube 21, the angles of the first swing arm 31 and the second swing arm 32 on it can be adjusted. When rotating the base 24, the base 24 and the fixing plate 26 only contact the stainless steel pad 27. The friction part is only the stainless steel pad 27, and the stainless steel pad 27 adopts an ultra-thin design. The small contact area and the low damping of the material itself make the slight damping of the product more convenient to rotate, but the overall fixation is very reliable. The setting of the cable clip 33 makes it convenient for users to fix the data cable of mobile phone or tablet. The elastic band can also be put on the two bent arms of the cable clip 33 to increase the number of data cables fixed, so that the data cable can be arranged close to the first swing arm 31 and the second swing arm 32 without shaking around. By rotating the adjustment screw 29 through the handle 292, the clamp 291 is raised relative to the first rubber pad 23, which can be clamped on the edge of the table for use.

[0043] Specifically, the damping assembly 2 7 includes a rotating head 3 71 and a rotating head 4 72. The rotating head 3 71 is located at the end of the swing arm 1 31 away from the rotating head 1 51, and the rotating head 4 72 is located at the top of the support tube 21. The rotating head 3 71 and the rotating head 4 72 are connected to the rotating head 1 51 and the rotating head 2 52 in the same way, all of which are connected through the oil storage damping mechanism 6. One end of the rotating head 4 72 extends into the interior of the rotating head 3 71 and is provided with a copper sheet 2 8 and an iron sheet 2 9. The side of the iron sheet 2 9 facing the copper sheet 2 8 is provided with the same oil storage structure as the iron sheet 1 62.

[0044] Specifically, the rotating head 72 is provided with a limiting seat 73 inside, and a linkage screw 74 with one end extending into the limiting member 64 is provided inside the rotating head 72. Two wave-shaped washers 75 are symmetrically arranged inside the limiting seat 73. One end of the threaded section of the linkage screw 74 passes through the limiting seat 73 and the wave-shaped washers 75 and is threadedly fitted with a locking nut 76. At least one flat surface is provided on the threaded section of the linkage screw 74, and waist-shaped hole washers 77 located on one side and inside the limiting seat 73 are respectively fitted on the threaded section.

[0045] In this embodiment, end caps 78 are fitted onto the opposite ends of rotating heads 71 ​​and 72, and sealing rings 79 are fitted onto the outside of the end caps 78. The damping assembly 7 has two sets of damping structures: one is an oil-storage damping mechanism 6, and the other is a damping structure composed of a linkage screw 74, a wave-shaped washer 75, and a waist-shaped hole washer 77. Since the damping assembly 7 is furthest from the universal ball joint 4, using two sets of damping can effectively improve the stability of supporting the mobile phone or tablet. When the angle is adjusted by rotating the swing arm 31, the swing arm 31 drives the rotating head 71 to rotate. The rotating head 71 drives the limiting member 64 to rotate through the limiting ring 65. During this process, the iron plate 62 rubs against the copper plate 61. At the same time, the limiting member 64 drives the linkage screw 74 to rotate. The plane on the linkage screw 74 drives the waist-shaped hole washer 77 to rub against the limiting seat 73. The rotating head 71 also drives the iron plate 9 to rub against the copper plate 8, which further improves the stability of the swing arm 31 after angle adjustment.

[0046] Specifically, the end of the second swing arm 32 away from the damping component 5 is connected to the universal ball joint 4 through the damping component 3 10. The damping component 3 10 includes a rotating head 5 101 and a rotating head 6 102. The rotating head 5 101 is connected to the second swing arm 32 through the damping component 4 11. The universal ball joint 4 is fixed to the outside of the rotating head 6 102. One end of the rotating head 6 102 is nested inside the rotating head 5 101. A copper nut 103 is fixedly nested inside the rotating head 5 101. The rotating head 6 102 is sequentially provided with a damping component 104, a thick washer 105, and a locking screw 2 106, one end of which passes through the thick washer 105 and the damping component 104 and is screwed into the copper nut 103.

[0047] In this embodiment, end caps 107 are fitted onto the opposite ends of rotating head 5 101 and rotating head 6 102. After locking screw 2 106 is tightened with copper nut 103, locking screw 2 106 presses damping member 104 and rotating head 5 101 together through thick washer 105. Rotating rotating head 6 102 rotates relative to damping member 104. The central axis of rotating head 5 101 is provided with matching slots and protrusions inside damping member 104, which restricts the rotation of damping member 104. When rotating head 6 102 rotates, it rubs against damping member 104, thereby achieving positioning of rotating head 6 102 and universal ball head 4. Universal ball head 4 17mm ball head is compatible with various ball head female seats on the market and can be used with mechanical chucks, Magsafe magnetic heads, etc.

[0048] Specifically, the damping assembly 11 includes a threaded head 111 and a connector 112 fixedly mounted on the rotating head 101. One end of the connector 112 is stepped and a smooth washer 113 is fitted at the step. The stepped end of the connector 112 extends into the interior of the threaded head 111 and is fitted with a limiting damping element 114. A copper nut 115 is fixedly nested inside the connector 112. One end of the threaded head 111 is screwed into the interior of the swing arm 32, and a locking screw 116 is provided at one end of the threaded head 111 that is screwed into the interior of the copper nut 115. Two round washers 117 and a spring 118 located between the two round washers 117 are also provided inside the threaded head 111. Both the round washers 117 and the spring 118 are fitted with the locking screw 116. An anti-reverse O-ring 119 located inside the swing arm 32 is also fitted outside the threaded head 111.

[0049] In this embodiment, the radial rotation angle is adjusted by rotating the rotating head 101 relative to the swing arm 32. The setting of spring 118 and round washer 117 reduces the wear of spring 118 and ensures the stability of locking screw 316. The rotating head 101 drives the connector 112 to rotate. The connector 112 drives the limiting damping element 114 to rub against the inside of the threaded head 111, so as to achieve the angle positioning of the connector 112 and the rotating head 101 after radial rotation.

[0050] In summary, this mobile phone and tablet holder features a design with an integrated oil reservoir 63 on the iron sheet. The oil reservoir 63 continuously lubricates the copper-iron friction interface, significantly reducing damping attenuation and improving adjustment stability and service life. Long-lasting damping is achieved simply by optimizing the iron sheet structure. The swing arms 1 (31) and 2 (32) are formed by hard extrusion of aluminum profiles and die-cast aluminum, eliminating the need for glue or auxiliary fasteners. This results in a stable structure and convenient assembly, avoiding the risk of loosening in traditional connections and enhancing overall reliability. The damping component 2 (7) integrates a dual damping system of oil reservoir friction and linkage screw 74 damping. Through wave-shaped pad elastic compensation and multi-level frictional resistance, it strengthens the rigidity of the far-end support, ensuring the stability of the mobile phone or tablet after multi-angle adjustment.
