Description

Technical Field

[0001] This application relates to the field of bracket technology for electronic devices, and particularly to a support component and bracket. Background Technology

[0002] Stands can support and fix products such as mobile phones, tablets, and computers. Stands usually include a support arm, one end of which is connected to a fixing structure for fixing the product, and the other end is connected to a fixing base. After the fixing base is fixed in the position to be fixed, the product is supported by the support arm, so that the user can view or perform corresponding operations. However, the support arm can only support the product at a specific angle, and the orientation adjustment of the product is limited. It cannot meet the user's need for multiple viewing angles of the product. The stand has low adjustment flexibility and is inconvenient to use. Utility Model Content

[0014] Given that the angle and orientation adjustment of the support arm 200 of the bracket in the prior art is limited and cannot meet the user's needs for multiple viewing angles of the product, resulting in low flexibility of bracket adjustment and inconvenience of use; the embodiments of this application provide a support component 10 that can meet the adjustment requirements of different orientations of the product and improve the flexibility of bracket adjustment.

[0015] Reference Figure 1 and Figure 2 The support assembly 10 includes a fixing base 100, a support arm 200, and a fixing member 300. The fixing base 100 and the fixing member 300 are connected through the support arm 200. The fixing base 100 is configured to connect to an adsorption member 20 that can be fixed in a preset position. The fixing member 300 is configured to fix the item to be fixed. The fixing method of the fixing member 300 for fixing the item to be fixed is not limited to clamping, supporting, magnetic attraction, etc. After the item to be fixed is fixed to the fixing member 300 and the adsorption member 20 is fixed in the preset position, the item to be fixed can be fixed in the preset position and supported by the support assembly 10.

[0016] The fixed base 100 includes a rotating member 110 and a mounting member 120 rotatably connected about a first axis X. The mounting member 120 is used to connect the adsorption member 20. The support arm 200 includes a first arm 210 and a second arm 220. The first arm 210 has a first end 211 and a second end 212. The first end 211 is rotatably connected to the rotating member 110 about a second axis Y. The second arm 220 has a third end 221 and a fourth end 222. The third end 221 is rotatably connected to the second end 212 about a third axis Z. The fixed member 300 is rotatably connected to the fourth end 222 about a fourth axis O. The first axis X, the second axis Y, and the third axis Z intersect each other, and the second axis Y is parallel to the fourth axis O.

[0017] The support assembly 10 in this application includes four rotating joints. The rotation directions of the fixing member 300 relative to the second support arm 220, the rotation direction of the second support arm 220 relative to the first support arm 210, the rotation direction of the first support arm 210 relative to the rotating member 110, and the rotation direction of the rotating member 110 relative to the mounting member 120 are all different. When the user needs to adjust the item, he / she can select to rotate the corresponding rotating joint to change the angle and orientation of the item. Through multi-axis adjustment, the support assembly 10 has high adjustment flexibility and can meet the usage needs of the item from multiple perspectives.

[0018] For example, taking the first axis X as being perpendicular to the surface at a preset position, when the user needs to change the orientation of the item along the surface at the preset position, this can be achieved by rotating the rotating member 110 relative to the mounting member 120, allowing the item to rotate around the first axis X; when the user needs to change the height of the item, this can be achieved by rotating the first support arm 210 relative to the rotating member 110, and / or rotating the fixing member 300 relative to the second support arm 220; when the user needs to adjust the pitch angle of the item based on the current orientation, this can be achieved by rotating the second support arm 220 relative to the first support arm 210, and / or rotating the fixing member 300 relative to the second support arm 220, allowing the item to flip around the third axis Z and / or the fourth axis O.

[0019] It should be noted that "the first axis X, the second axis Y, and the third axis Z intersect each other" means that any two axes intersect, and in three-dimensional space, the first axis X and the second axis Y do not intersect and are not parallel, or the first axis X and the second axis Y intersect but are not parallel, so that the rotation directions of the components rotating around the corresponding axes are different. In one embodiment, the first axis X, the second axis Y, and the third axis Z are perpendicular to each other, and the first axis X is perpendicular to the surface of the rotating component 110 facing away from the mounting component 120. Then, the second axis Y and the third axis Z are both parallel to the surface of the rotating component 110. The user can rotate the first support arm 210, the second support arm 220, and the fixing component 300 to a position parallel to the surface of the rotating component 110, which facilitates the storage and carrying of the support assembly 10.

[0020] Both the first arm 210 and the second arm 220 can be configured as straight rods, with the first end 211 and the second end 212 being opposite ends of the first arm 210, and the third end 221 and the fourth end 222 being opposite ends of the second arm 220. The first arm 210 and the second arm 220 extend in the same direction. The second end 212 and the third end 221 are directly connected and can rotate relative to each other, which increases the length of the support arm 200 and improves the sensitivity of the support assembly 10 in adjusting the height of the object. Understandably, at least one of the first arm 210 and the second arm 220 can be configured as a telescopic rod, making the length of the support arm 200 adjustable, thereby increasing the range of motion of the fixing member 300 and enabling the support assembly 10 to be applied to different usage scenarios.

[0021] The first arm 210 and the second arm 220 can also be configured in a curved shape. For example, both the first arm 210 and the second arm 220 include two segments that bend towards each other. Since the first arm 210 and the second arm 220 are curved, the adjustment of the orientation of the object by the support assembly 10 is diversified, which can further improve the flexibility of the adjustment of the support assembly 10.

[0022] Understandably, the support component 10 has an unfolded state and a folded state. When the support component 10 is in the folded state (e.g., Figure 1 and Figure 2 As shown, the fixing component 300, the support arm 200, the rotating component 110 and the mounting component 120 are stacked in sequence, which effectively reduces the volume of the support component 10 and makes it easier to store and carry the support component 10.

[0023] When the support assembly 10 switches from a folded state to an unfolded state, at least the first arm 210 rotates about the second axis Y away from the rotating member 110 by a preset angle, which is an acute angle, a right angle, or an obtuse angle, so that the support arm 200 unfolds relative to the rotating member 110; or, at least the fixing member 300 rotates about the fourth axis O away from the rotating member 110 by a preset angle, which is an acute angle, a right angle, or an obtuse angle, so that the fixing member 300 unfolds relative to the support arm 200. Understandably, based on the unfolding of the support arm 200 relative to the rotating member 110, the second arm 220 can be further rotated relative to the first arm 210 to change the orientation of the item.

[0024] In one embodiment, reference is made to Figure 2 and Figure 3 The rotating component 110 includes a first main body 111 and a first rotating seat 112 protruding from the mounting component 120 relative to the first main body 111. A first end 211 is rotatably connected to the first rotating seat 112. (Refer to...) Figure 2 and Figure 4The fixing member 300 includes a second main body 310 and a second rotating seat 320 protruding relative to the second main body 310, and the fourth end 222 is rotatably connected to the second rotating seat 320; when the support assembly 10 is in the folded state, the first main body 111 is parallel to the second main body 310, and the first rotating seat 112, the support arm 200 and the second rotating seat 320 are all located between the first main body 111 and the second main body 310. Thus, when the support assembly 10 is in the folded state, the support arm 200 is stored in the space between the first rotating seat 112 and the second rotating seat 320. At the same time, the centers of the first rotating seat 112, the support arm 200 and the second rotating seat 320 are on the same plane, and are stored in the space between the first main body 111 and the second main body 310. Based on the rotatable connection between the support arm 200 and the rotating component 110 and the rotatable connection between the fixing component 300 and the support wall, the combination of the support arm 200, the fixing component 300 and the rotating component 110 is more compact, which can reduce the space occupied by the support assembly 10 in the folded state and facilitate storage.

[0025] Furthermore, when the support assembly 10 is in the folded state, the first rotating seat 112 and the second rotating seat 320 are distributed along the edge of the first main body 111 in a direction parallel to the third axis Z, so as to maximize the length of the support arm 200 and the range of motion of the fixing member 300, making the angle and orientation adjustment of the item more flexible.

[0026] In one embodiment, the rotating member 110 has a rotation range of 0°-360° relative to the fixed member 300 about the first axis X, that is, the rotating member 110 can rotate 360° relative to the fixed member 300, so that the orientation of the item along the preset position surface can be adjusted 360°; the first support arm 210 has a rotation range of 0°-270° relative to the rotating member 110 about the second axis Y, that is, the support arm 200 can rotate from a position stacked on the surface of the rotating member 110 to a position attached to the periphery of the rotating member 110, so as to adjust... The height of the item is adjusted, and the item is simultaneously rotated at a large angle around the second axis Y. The second support arm 220 rotates relative to the first support arm 210 around the third axis Z with a range of 0°-360°, meaning the orientation of the item perpendicular to the preset position surface can be adjusted 360°. The fixing member 300 rotates relative to the second support arm 220 around the fourth axis O with a range of 0°-180°, meaning the fixing member 300 can rotate from a position overlapping with the support arm 200 to the same height as the support arm 200, allowing the item to tilt at a large angle. Thus, all four rotating joints within the support assembly 10 can be adjusted at large angles, meeting the multi-view adjustment needs of the item.

[0027] Specifically, the first arm 210 can be rotatably connected to the first rotating seat 112 via the first rotating shaft 230. Damping is provided between the first arm 210 and the first rotating shaft 230, or between the first rotating shaft 230 and the first rotating seat 112, so that the first arm 210 can be suspended when rotated to any position relative to the first rotating seat 112. Similarly, the second arm 220 can be rotatably connected to the second rotating seat 320 via the second rotating shaft 240. Damping is provided between the second arm 220 and the second rotating shaft 240, or between the second rotating shaft 240 and the second rotating seat 320, so that the fixing member 300 can be suspended when rotated to any position relative to the second arm 220.

[0028] Additionally, the first arm 210 and the second arm 220 are connected, as shown in the reference. Figure 5 One of the first arm 210 and the second arm 220 has a protruding insertion portion 250, and the other has an insertion groove 260. The insertion portion 250 is inserted into the insertion groove 260. When the second arm 220 rotates relative to the first arm 210, the insertion portion 250 can rotate around the third axis Z within the insertion groove 260. Both the first arm 210 and the second arm 220 can have cavities inside, and the cavities can be equipped with rotating shafts or damping structures to support the insertion portion 250 and provide rotational damping.

[0029] The first rotating seat 112 has two spaced-apart first support portions 1121. The two ends of the first rotating shaft 230 are respectively inserted into the two first support portions 1121. The first end 211 is sleeved on the outside of the first rotating shaft 230, so that the support arm 200 can rotate smoothly relative to the rotating member 110. The second rotating seat 320 has two spaced-apart second support portions 321. The two ends of the second rotating shaft 240 are respectively inserted into the two second support portions 321. The fourth end 222 is sleeved on the outside of the second rotating shaft 240, so that the fixing member 300 can rotate smoothly relative to the support arm 200.

[0030] Understandable, refer to Figure 2 To ensure that the rotating component 110 is stably positioned relative to the mounting component 120 after rotating at a preset angle, thus making the support assembly 10 more reliable, the fixed base 100 also includes a damping component 130. The damping component 130 is not limited to being made of flexible materials such as rubber or silicone. The damping component 130 is clamped between the rotating component 110 and the mounting component 120 and is in contact with the rotating component 110. On the one hand, by setting the damping component 130 between the rotating component 110 and the mounting component 120, direct contact between the rotating component 110 and the mounting component 120 is avoided, which would cause wear. On the other hand, the damping component 130 can deform to make close contact with the rotating component 110 or the mounting component 120 and increase the friction between the rotating component 110 and the mounting component 120, so that the rotating component 110 can be stably positioned after rotating at a preset angle.

[0031] The damping element 130 can be fixed to the rotating element 110 or to the mounting element 120; in a specific embodiment, refer to Figure 6 The rotating component 110 has a fixing groove 113 on the side facing the mounting component 120. A portion of the damping component 130 is embedded in the fixing groove 113, and a portion protrudes to the outside of the fixing groove 113 and contacts the mounting component 120. The connection method between the damping component 130 and the mounting component 120, and between the damping component 130 and the rotating component 110, is not limited to abutment, bonding, etc. The damping component 130 can be set as a ring, so that the rotating component 110 can maintain a stable position due to rotational damping when rotating to any angle.

[0032] Furthermore, refer to Figure 7 The fixed base 100 also includes an adjustment assembly 140, which is clamped between the rotating member 110 and the mounting member 120. The adjustment assembly 140 includes an elastic member 141 and a ball bearing 142. The two ends of the elastic member 141 are respectively connected to the mounting member 120 and the ball bearing 142, and at least a portion of the ball bearing 142 protrudes towards the rotating member 110 relative to the mounting member 120. (Refer to...) Figure 6 The rotating component 110 is provided with multiple recessed adjustment slots 114, which are arranged around the first axis X. The ball 142 can move in and out of the adjustment slots 114 as the rotating component 110 and the mounting component 120 rotate relative to each other. On the one hand, the groove wall of the adjustment slot 114 can limit the ball 142 and help the damping component 130 stabilize the position of the rotating component 110 relative to the mounting component 120. On the other hand, when the user rotates the rotating component 110, as the ball 142 moves in and out of different adjustment slots 114, the support component 10 emits a "click" sound, which can indicate the rotation process of the rotating component 110 to the user and improve the operating feel.

[0033] Understandably, the surface of the ball 142 facing the rotating member 110 is set as an arc surface or a spherical cap surface, and the adjustment groove 114 is set as an arc groove, so as to facilitate the transition between adjacent adjustment grooves 114 and the ball 142 entering and exiting the adjustment groove 114; in the adjacent adjustment grooves 114, the groove wall of one adjustment groove 114 is connected to the groove wall of another adjustment groove 114, so that the transition of the ball 142 between adjacent adjustment grooves 114 is smoother.

[0034] Additionally, refer to Figure 7The mounting component 120 is provided with a limiting groove 121 on the side facing the rotating component 110. At least part of the elastic component 141 is placed in the limiting groove 121. The limiting groove 121 has an opening 122 at one end along the extension and retraction direction of the elastic component 141. The elastic component 141 is connected to the ball 142 through the opening 122. The limiting groove 121 can guide the extension and retraction of the elastic component 141, preventing the elastic component 141 from bending or tilting during the extension and retraction process, so that the elastic component 141 maintains elastic resistance to the ball 142, and the ball 142 can smoothly transition between different adjustment grooves 114.

[0035] In one embodiment, the ball 142 and the adjusting groove 114 are arranged radially along the rotating member 110; for example, the mounting member 120 surrounds the outer periphery of the rotating member 110, the adjusting groove 114 is disposed on the periphery of the rotating member 110, the limiting groove 121 is disposed on the edge of the mounting member 120, the opening of the limiting groove 121 faces the periphery of the rotating member 110, the extension and retraction direction of the elastic member 141 is parallel to the radial direction of the rotating member 110, the ball 142 is connected to one end of the elastic member 141 and distributed on the periphery of the rotating member 110; when the rotating member 110 rotates relative to the mounting member 120, the ball 142 rotates around the rotating member 110 and enters and exits different adjusting grooves 114.

[0036] Alternatively, in another embodiment, such as Figure 7 As shown, the arrangement direction of the adjusting groove 114 and the ball 142 is the same as the arrangement direction of the rotating part 110 and the mounting part 120. The ball 142 protrudes relative to the mounting part 120 to the side of the mounting part 120 facing the rotating part 110. The rotating part 110 is provided with multiple adjusting grooves 114 on the side facing the mounting part 120. The opening 122 of the limiting groove 121 faces the rotating part 110. The arrangement direction of the rotating part 110 and the mounting part 120 is the same as the extension and retraction direction of the telescopic part. When the rotating part 110 rotates relative to the mounting part 120, the ball 142 rotates between the mounting part 120 and the rotating part 110 and enters and exits different adjusting grooves 114.

[0037] In addition, multiple adjustment components 140 can be provided, and the multiple adjustment components 140 are distributed at intervals around the first axis X. The balls 142 in the multiple adjustment components 140 can abut against the rotating member 110 from different positions to keep the rotating member 110 in balance and make the rotation of the rotating member 110 more stable.

[0038] The rotational connection between the rotating member 110 and the mounting member 120 is not limited to the following: the rotating member 110 and the mounting member 120 can achieve relative rotation by using a hole-shaft structure. For example, one of the rotating member 110 and the mounting member 120 is provided with a protruding rotating part, and the other is provided with a mounting hole. The rotating part is inserted into the mounting hole and can rotate around the first axis X in the mounting hole.

[0039] In one embodiment, reference is made to Figure 8 The rotating member 110 has a first mating portion 115 on the edge facing the mounting portion, and the mounting member 120 has a second mating portion 123 on the edge facing the rotating member 110. The first mating portion 115 and the second mating portion 123 are mated together and can rotate relative to each other around the first axis X. Specifically, the first mating portion 115 and the second mating portion 123 have a recessed groove 1231 and a protruding protrusion 1151. The protrusion 1151 is embedded in the groove 1231 and can rotate within the groove 1231 to realize the relative rotation of the rotating member 110 and the mounting member 120.

[0040] Understandably, the groove 1231 and the protrusion 1151 can be provided on the radial side of the rotating member 110 or the mounting member 120, or on the side of the rotating member 110 and the mounting member 120 along their respective arrangement directions. For example... Figure 8 In the embodiment shown, a protrusion 1151 is disposed on the side of the first docking portion 115 facing the mounting member 120, and a groove 1231 is disposed on the side of the second docking portion 123 facing the rotating member 110. Both the protrusion 1151 and the groove 1231 are annular. The protrusion 1151 is embedded in the groove 1231, so that the rotating member 110 can rotate relative to the mounting member 120.

[0041] It should be noted that for the method of using electric control to fix the adsorption component 20 in the preset position, refer to... Figure 2 The mounting component 120 may have a mounting cavity 124 inside, which is used to accommodate electronic control devices, such as a suction structure for evacuating the adsorption component 20, a circuit board, a button transmission mechanism, etc. By providing a first mating part 115 on the edge of the rotating component 110 and a second mating part 123 on the edge of the mounting component 120, the cooperation between the protrusion 1151 and the groove 1231 not only enables the relative rotation of the rotating component 110 and the mounting component 120, but also lengthens the path for external impurities to enter the interior of the mounting component 120, thereby blocking external impurities from entering the mounting cavity 124 and achieving a dustproof effect.

[0042] In one embodiment, reference is made to Figure 2 The mounting component 120 includes a third main body 125 and a partition 126. The third main body 125 defines a mounting cavity 124. The partition 126 covers the side of the second docking portion 123 facing the rotating component 110 to close the mounting cavity 124. The connection method between the partition 126 and the third main body 125 is not limited to threaded connection, snap-fit, etc. The adsorption component 20 is connected to the side of the third main body 125 facing away from the partition 126. The damping component 130 is disposed inside the first docking portion 115. Both the damping component 130 and the adjustment component 140 can be disposed between the rotating component 110 and the partition 126.

[0043] Reference Figure 8The inner side of the first docking part 115 is provided with a protruding guide part 1152, and the periphery of the partition plate 126 is provided with a recessed guide groove 1261. The guide part 1152 is slidably connected in the guide groove 1261. Both the guide part 1152 and the guide groove 1261 can be set as annular. When the rotating part 110 rotates relative to the mounting part 120, the guide part 1152 slides under the guidance of the guide groove 1261, making the rotation of the rotating part 110 more stable.

[0044] Taking a protrusion 1151 located on the first docking portion 115 and a groove 1231 located on the second docking portion 123 as an example, a guide portion 1152 is located on the side of the protrusion 1151 facing away from the second docking portion 123, and the guide portion 1152 and the guide groove 1261 are arranged radially along the rotating member 110; then, the cooperation between the guide portion 1152 and the guide groove 1261 can further lengthen the path for external impurities to enter the interior of the mounting member 120, thereby improving the dustproof effect.

[0045] Furthermore, a snap-fit ​​portion 1262 is provided on the periphery of the partition 126. The snap-fit ​​portion 1262 and the guide portion 1152 snap-fit ​​together along the arrangement direction of the rotating member 110 and the mounting member 120, thereby limiting the rotating member 110 and the mounting member 120 in their arrangement direction and in the radial direction of the rotating member 110, achieving a stable fit between them. In addition, a guide groove 1261 is provided on the side of the snap-fit ​​portion 1262 facing the third main body portion 125. When the snap-fit ​​portion 1262 is snapped with the guide portion 1152, the guide portion 1152 is slidably connected in the guide groove 1261, so that the rotating member 110 can rotate relative to the mounting member 120 under the guidance of the guide groove 1261 while being limited.

[0046] In one embodiment, reference is made to Figure 1 and Figure 2 The fastener 300 secures the item by magnetic attraction. The fastener 300 has a magnetic surface 330 for placing the item. The magnetic surface 330 provides a flat contact position for the item. The item to be secured can be attached to the magnetic surface 330 and secured by the fastener 300.

[0047] The fastener 300 includes a magnetic part 340, which is a component with magnetic force, such as a magnet; the second main body 310 is provided with a mounting groove 311, and the magnetic part 340 is embedded in the mounting groove 311. The mounting groove is adapted to the shape of the magnetic part 340, and is not limited to being circular, annular, arc-shaped, polygonal, etc.

[0048] The fastener 300 also includes a gasket 360, which is attached to the top of the magnetic part 340 and seals the magnetic part 340 within the mounting groove 311. The gasket 360 can be configured as a flexible structure, allowing it to flexibly contact the item to be fastened.

[0049] like Figure 1 and Figure 9 In the embodiment shown, the fastener 300 is hollow and the mounting groove is annular to reduce the weight of the fastener 300 and the magnetic part 340, thereby making the support assembly 10 lighter.

[0050] The fastener 300 also includes at least one limiting part 350 and one magnetic suction part 340; if there are multiple magnetic suction parts 340, the multiple magnetic suction parts 340 are arranged at intervals along the extension direction of the mounting groove, and the limiting part 350 is disposed between adjacent magnetic suction parts 340; if there is only one magnetic suction part 340 and one limiting part 350, a notch 341 is formed between the two opposite ends of the magnetic suction parts 340, and the limiting part 350 is disposed in the notch 341; the limiting part 350 can limit the magnetic suction part 340, so that the magnetic suction part 340 is firmly fixed in the mounting groove.

[0051] Reference Figure 10 and Figure 11 In this application, an embodiment also provides a support, which includes the aforementioned support component 10. The support also includes an adsorption component 20 and an air extraction component 30. The adsorption component 20 is configured as a flexible structure, which can deform and return to its original shape under external air pressure. The adsorption component 20 is connected to the mounting component 120. The side of the adsorption component 20 facing away from the mounting component 120 is provided with an adsorption cavity 21. The adsorption component 20 also has an air extraction hole 22 communicating with the adsorption cavity 21. The air extraction component 30 can be accommodated in the mounting cavity 124. The air extraction component 30 is connected to the air extraction hole 22 through a pipeline and is configured to extract gas in the adsorption cavity 21 through the air extraction hole 22 so that a vacuum negative pressure is formed in the adsorption cavity 21 and fixed in a preset position.

[0052] When the adsorption element 20 contacts the preset position, the adsorption chamber 21 is sealed. As the gas extraction component 30 gradually extracts the gas in the adsorption chamber 21, the adsorption element 20 continues to deform. Since the adsorption element 20 is flexible, the deformation of the adsorption element 20 can be adapted to the surface shape of the preset position. As the gas in the adsorption chamber 21 gradually decreases, the adsorption element 20 gradually approaches the preset position, and the adsorption force between it and the preset position gradually increases until the adsorption element 20 is completely attached to the surface of the preset position.

[0053] In one embodiment, the bracket includes an operation key, and the air extraction assembly 30 includes a power element 31, which is configured as an air pump or the like. The operation key is electrically connected to the power element 31. When the user needs to fix the bracket in a preset position, the power element 31 starts to perform an air extraction action according to the input command of the operation key by operating the operation key (such as pressing, pushing, turning, etc.). After the power element 31 has performed the air extraction action for a preset time, the power element 31 stops extracting air. At this time, the adsorption member 20 adsorbs and fixes itself in the preset position.

[0054] In another embodiment, the bracket includes a trigger button 40, the adsorption member 20 is provided with a moving channel 23, the moving channel 23 is connected to the adsorption chamber 21, the trigger button 40 is movably disposed in the moving channel 23 and can enter and exit the adsorption chamber 21; the bracket also includes a trigger switch 50 electrically connected to the power element 31. When the user needs to fix the bracket in a preset position, he presses the fixing seat 100 in the preset position, the adsorption chamber 21 of the adsorption member 20 is closed by the preset position, the trigger button 40 is pushed by the preset position and moves toward the fixing seat 100. When the trigger button 40 moves and triggers the trigger switch 50, the power element 31 begins to extract the gas in the adsorption chamber 21 until the adsorption member 20 adsorbs and is fixed in the preset position.
