DETAILED DESCRIPTION

[0026] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Now, the preferred embodiments of the present application will be described in detail with reference to the drawings.

[0027] As shown in Figures 1 to 3 The utility model discloses an electronic device support 100, including: base 110 and setting on base 110 rotating component 120, rotating component 120 on the rotation connection has folding arm assembly 130, and folding arm assembly 130 is away from rotating component 120 one end rotation connection has support platform 140, base 110 includes bottom plate 112 and the rotation connection of the outer ring of bottom plate 112 A plurality of first extension arm 114, and first extension arm 114 can rotate to the side that is away from support platform 140 with bottom plate 112 adhesion or present certain angle of repose, support platform 140 includes support plate 142 and the rotation connection of the outer ring of support plate 142 A plurality of second extension arm 144, and second extension arm 144 can rotate to the side that is away from base 110 with support plate 142 adhesion or present certain angle of repose, when folding arm assembly 130 folds, base 110 and support platform 140 can be close to each other to hold folding arm assembly 130 between rotating component 120 and support plate 142.

[0028] Specifically, base 110 is rotationally connected with folding arm assembly 130 through rotating component 120, and the other end of folding arm assembly 130 is rotationally connected with support platform 140, and the connection mode enables the relative movement of the parts of electronic device support 100, and different forms are realized. The rotation of the rotating component 120 is in the horizontal direction, and the support platform 140 is in the vertical direction and is tilted. The plurality of first extension arms 114 arranged at the outer ring of the bottom plate 112 can increase the contact area with the placement table when the base 110 is placed on the table or the like, and the stability of the base 110 is improved. Similarly, the plurality of second extension arms 144 arranged at the outer ring of the support plate 142 can increase the contact area with the electronic device when the electronic device is placed on the support platform 140, and the electronic device is prevented from accidentally falling off the support platform 140, and the stability of the electronic device is improved. In addition, when the electronic device support 100 is folded, the first extension arms 114 can be rotated to the state of adhesion or a certain angle with the bottom plate 112, and the second extension arms 144 can be rotated to the state of adhesion or a certain angle with the support plate 142. It should be noted that the state of a certain angle is not completely adhesion, and the rotation to the state of adhesion can be determined according to actual needs.

[0029] The electronic device support 100 provided by the embodiment of the present application comprises a rotating assembly 120 arranged on the base 110, a folding arm assembly 130 rotationally connected to the rotating assembly 120, and a support table 140 rotationally connected to one end of the folding arm assembly 130 away from the rotating assembly 120. When the rotating assembly 120 rotates relative to the base 110, the folding arm assembly 130 and the support table 140 can be driven to rotate synchronously with the rotating assembly 120, and the folding arm assembly 130 can rotate independently relative to the rotating assembly 120, and the support table 140 can also rotate independently relative to the folding arm assembly 130, which is conducive to adjusting different postures of the electronic device, thereby meeting the use requirements of different people and different scenes. In addition, in order to ensure the stability of the base 110 placed on the table top, the first extension arm 114 can be unfolded relative to the bottom plate 112 to increase the contact support area with the table top. Similarly, when the electronic device is placed on the support table 140, the second extension arm 144 can be unfolded relative to the support plate 142 to increase the contact support area with the electronic device. When the electronic device support 100 needs to be folded, the first extension arm 114 is only needed to be rotated relative to the bottom plate 112 to be attached to or at a certain angle with the side away from the support table 140, and the second extension arm 144 is only needed to be rotated relative to the support plate 142 to be attached to or at a certain angle with the side away from the base 110. Finally, the folding arm assembly 130 is folded to clamp the folding arm assembly 130 between the rotating assembly 120 and the support plate 142. In this way, the unfolding and folding ratio can be improved, the folding degree of the electronic device support 100 is greatly improved, and the folding space is further compressed. Whether put into a bag or held in hand, it will not occupy too much space, improving the convenience of the user when carrying.

[0030] As shown in Figure 4 The rotating assembly 120 comprises a rotating seat 121, a first gear 122, at least one second gear 123, and a rotating disc 124. The inner ring of the rotating seat 121 is provided with an inner ring gear 1212, the first gear 122 is located at the rotation center of the rotating seat 121, the second gear 123 is located between the first gear 122 and the rotating seat 121, so that the second gear 123 is meshed with the first gear 122 and the inner ring gear 1212 respectively; the rotating disc 124 is connected with one side of the thickness direction of the first gear 122, the rotating seat 121 is rotationally connected with the bottom plate 112, and the folding arm assembly 130 is connected with the rotating seat 121; when the rotating disc 124 is rotated, the rotating seat 121 can be driven to rotate reversely, or when the rotating seat 121 is rotated, the rotating disc 124 can be driven to rotate reversely.

[0031] Specifically, by setting the inner ring of the rotating seat 121 with the inner ring gear 1212, and setting the rotating center of the rotating seat 121 with the first gear 122, when the second gear 123 located between the first gear 122 and the rotating seat 121 is engaged with the first gear 122 and the inner ring gear 1212 respectively, the required linkage relationship can be formed. At this time, when the rotating disc 124 connected to one side of the first gear 122 in the thickness direction rotates, it drives the first gear 122 to rotate synchronously, and further reversely rotates the rotating seat 121, thereby achieving the purpose of rotating adjustment of the support table 140. It can be understood that the rotating seat 121 can also be directly rotated, or the folding arm assembly 130 or the support table 140 can be rotated to indirectly rotate the rotating seat 121, and the purpose of rotating adjustment of the support table 140 can also be achieved. Among them, the second gear 123 can be provided with only one, or two or three can be provided in equal distribution, as long as the required transmission can be ensured.

[0032] As shown in Figure 4 and Figure 5 , the inner ring of the rotating seat 121 is provided with an annular groove 1214 corresponding to the inner ring gear 1212, the diameter of the annular groove 1214 is greater than the diameter of the inner ring gear 1212, the rotating assembly 120 further comprises an annular cover plate 125, the annular cover plate 125 is arranged in the annular groove 1214; the second gear 123 is provided in plurality, and the side of the annular cover plate 125 facing the first gear 122 is provided with a plurality of connecting columns 1252, the bottom plate 112 is provided with fasteners 1122 corresponding to the connecting columns 1252 in one-to-one connection, the connecting columns 1252 are provided in one-to-one correspondence with the second gear 123, and the second gear 123 is sleeved on the connecting columns 1252.

[0033] Specifically, by setting the inner ring of the rotating seat 121 with the annular groove 1214 corresponding to the inner ring gear 1212, the annular groove 1214 is located on one side of the inner ring gear 1212 in the thickness direction, which facilitates the arrangement of the annular cover plate 125 in the annular groove 1214 and does not affect the normal rotation of the first gear 122 and the second gear 123. And by setting a plurality of connecting columns 1252 on the side of the annular cover plate 125 facing the first gear 122, and setting fasteners 1122 corresponding to the connecting columns 1252 in one-to-one connection on the bottom plate 112, the bottom plate 112 and the annular cover plate 125 can be connected, thereby achieving the purpose of limiting the rotating seat 121, avoiding the rotating seat 121 from loosening from the bottom plate 112, and being conducive to ensuring the stability of the connection. Among them, the fasteners 1122 can adopt screws, in order to avoid the screws from being outwardly protruding from the bottom of the bottom plate 112, a countersunk hole can be provided on the bottom plate 112 to accommodate the screw nut. In addition, the connecting columns 1252 are provided in one-to-one correspondence with the second gear 123, and the second gear 123 is sleeved on the connecting columns 1252, which can make the second gear 123 rotate relative to the connecting columns 1252 to ensure the stability during meshing transmission.

[0034] As shown in Figure 4 and Figure 6 , the rotating assembly 120 further comprises a limiting assembly 126, the limiting assembly 126 comprises a positioning seat 1262 and an abutting block 1264 in sliding connection with the positioning seat 1262, an elastic member (not shown in the figure) is arranged between the positioning seat 1262 and the abutting block 1264, the positioning seat 1262 is connected with the annular cover plate 125, the positioning seat 1262 is formed with a sliding groove 1262a and a wedge-shaped limiting groove 1262b connected with the sliding groove 1262a, the abutting block 1264 comprises a sliding part 1264a and an abutting part 1264b connected with each other, the sliding part 1264a is in sliding connection with the sliding groove 1262a, and the abutting part 1264b can abut against the wedge-shaped limiting groove 1262b, and the abutting part 1264b elastically abuts against the first gear 122 or the inner tooth ring 1212.

[0035] Specifically, the positioning seat 1262 is connected with the annular cover plate 125, which is conducive to ensuring the stability of the position where the limiting assembly 126 is located. In the initial state, the abutting part 1264b can be clamped in the tooth groove of the first gear 122 or the inner tooth ring 1212 under the influence of the elastic member, so as to limit the rotation of the rotating seat 121 and ensure the stability in use. When the rotating disc 124 or the rotating seat 121 is rotated by external force, the abutting part 1264b is forced to retract into the positioning seat 1262, at this time, the elastic force of the elastic member is overcome, and the elastic potential energy of the elastic member is accumulated. When the abutting part 1264b passes the current tooth top and corresponds to the next tooth groove, the abutting part 1264b is clamped in the next tooth groove under the elastic action of the elastic member. In this way, the rotation has a certain damping force, and there is a corresponding impact sound in the rotation process, which is conducive to providing a certain comfort in the sense of touch and sound. The elastic member can be a compression spring. In order to ensure the smoothness of the sliding between the positioning seat 1262 and the abutting block 1264, the sliding groove 1262a matched with the abutting block 1264 is arranged on the positioning seat 1262. In order to avoid the abutting block 1264 from being separated from the sliding groove 1262a, the wedge-shaped limiting groove 1262b connected with the sliding groove 1262a is further arranged on the positioning seat 1262, so as to ensure the stability of the limiting assembly 126 in use by limiting the abutting part 1264b.

[0036] As shown in Figure 5 , the bottom plate 112 is provided with an annular sliding groove 1124, and the side of the rotating seat 121 facing the bottom plate 112 is provided with a plurality of arc-shaped protrusions 1216 in a spaced manner, and the arc-shaped protrusions 1216 are in sliding connection with the annular sliding groove 1124.

[0037] Specifically, by arranging the annular sliding groove 1124 on the bottom plate 112 and the plurality of arc-shaped protrusions 1216 arranged on the side of the rotating seat 121 facing the bottom plate 112, when the bottom plate 112 is matched with the rotating seat 121, the arc-shaped protrusions 1216 are in sliding connection with the annular sliding groove 1124, which is conducive to ensuring the stability and reliability of the sliding of the bottom plate 112 and the rotating seat 121.

[0038] As shown in Figure 4 , the first gear 122 is provided with a circular boss 1222 on the side facing the rotating disc 124, the circular boss 1222 is provided with a pin shaft 1224, the rotating disc 124 is provided with a limiting hole 1242 corresponding to the pin shaft 1224, the circular boss 1222 passes through the annular cover plate 125 and is attached to the rotating disc 124, and the pin shaft 1224 is inserted into the limiting hole 1242.

[0039] Specifically, by arranging the circular boss 1222 on the side of the first gear 122 facing the rotating disc 124, it is convenient for the circular boss 1222 to pass through the annular cover plate 125 and be attached to the rotating disc 124 while limiting the first gear 122 by the annular cover plate 125, so that the first gear 122 is connected with the rotating disc 124. When connected, by arranging the pin shaft 1224 on the circular boss 1222 and arranging the limiting hole 1242 corresponding to the pin shaft 1224 on the rotating disc 124, only the pin shaft 1224 needs to be inserted into the limiting hole 1242, which is conducive to improving the convenience when connecting.

[0040] As shown in Figure 1 and Figure 3 , the bottom plate 112 is rotatably connected with the first extension arm 114 through the first rotating assembly 150, and the rotation angle between the bottom plate 112 and the first extension arm 114 is 0° to 180°; the supporting plate 142 is connected with the second extension arm 144 through the second rotating assembly 160, and the rotation angle between the supporting plate 142 and the second extension arm 144 is 0° to 180°.

[0041] Specifically, when the electronic device support 100 is in use, the first extension arm 114 can be folded from the state of being attached to the side away from the supporting table 140 relative to the bottom plate 112 to the state of being flush relative to the bottom plate 112, that is, the rotation angle between the bottom plate 112 and the first extension arm 114 is 0° to 180°. Similarly, the second extension arm 144 can be folded from the state of being attached to the side away from the base 110 relative to the supporting plate 142 to the state of being flush relative to the supporting plate 142, that is, the rotation angle between the supporting plate 142 and the second extension arm 144 is 0° to 180°. In the above manner, it can be ensured that the unfolded state has sufficient supporting space, and the folded state can better compress the occupied space, which is conducive to improving the unfolding and folding ratio, thereby ensuring the stability of the use state and the portability of the folded state.

[0042] As shown in Figure 7 , the first rotating assembly 150 comprises oppositely arranged first connecting pieces 152 and first rotating pieces 154 rotatably connected with the two first connecting pieces 152 respectively, the first rotating pieces 154 oppositely have first through holes 1542 and first limiting notches 1544 corresponding to the first through holes 1542, the first connecting pieces 152 have first rotating shafts 1522 and first limiting shafts 1524 arranged side by side, the first rotating shafts 1522 are rotatably connected with the first through holes 1542, and the first limiting shafts 1524 are used for limiting corresponding to the first limiting notches 1544, one of the first connecting pieces 152 is connected with the bottom plate 112, and the other first connecting piece 152 is connected with the first extending arm 114.

[0043] Specifically, one of the first connecting pieces 152 is connected with the bottom plate 112, and the other first connecting piece 152 is connected with the first extending arm 114, which facilitates the connection of the bottom plate 112 and the first extending arm 114, and the first through holes 1542 arranged on the first rotating pieces 154 are rotatably connected with the first rotating shafts 1522, which can ensure that the two sides of the first rotating pieces 154 can be rotatable relative to the corresponding first connecting pieces 152, and facilitate the folding of the first extending arm 114 relative to the bottom plate 112 to the state of being attached to the side away from the support table 140. When it is needed to be unfolded, it only needs to be rotated in the opposite direction. Since the first extending arm 114 also needs to play a supporting role, after the first extending arm 114 is rotated to the state of being parallel to the bottom plate 112, the first limiting shafts 1524 are limited corresponding to the first limiting notches 1544 to ensure the stability of the current state and cannot be rotated any more, thereby playing a supporting role.

[0044] Please continue to refer to Figure 7 , the second rotating assembly 160 comprises oppositely arranged second connecting pieces 162 and second rotating pieces 164 rotatably connected with the two second connecting pieces 162 respectively, the second rotating pieces 164 oppositely have second through holes 1642 and second limiting notches 1644 corresponding to the second through holes 1642, the second connecting pieces 162 have second rotating shafts 1622 and second limiting shafts 1624 arranged side by side, the second rotating shafts 1622 are rotatably connected with the second through holes 1642, and the second limiting shafts 1624 are used for limiting corresponding to the second limiting notches 1644, one of the second connecting pieces 162 is connected with the support plate 142, and the other second connecting piece 162 is connected with the second extending arm 144.

[0045] Similarly, one of the second connecting pieces 162 is connected with the support plate 142, and the other second connecting piece 162 is connected with the second extension arm 144, which facilitates the connection of the support plate 142 and the second extension arm 144, and the relative rotation of the two sides of the second rotating piece 164 and the corresponding second connecting piece 162 through the second through hole 1642 and the second rotating shaft 1622, which can ensure that the second extension arm 144 can be folded to the state of being attached to the side away from the base 110 relative to the support plate 142. When it is needed to be unfolded, it only needs to be rotated in the opposite direction. Since the second extension arm 144 also needs to play a supporting role, after the second extension arm 144 is rotated to the state of being parallel to the support plate 142, the current state is stabilized by the corresponding limiting of the second limiting shaft 1624 and the second limiting notch 1644, and cannot be rotated again, thereby playing a supporting role.

[0046] As shown in Figure 1 and Figure 2 , the folding arm assembly 130 includes a first connecting arm 132 and a second connecting arm 134 arranged on opposite sides of the first connecting arm 132. The first connecting arm 132 is rotationally connected with the second connecting arm 134. The rotating assembly 120 is provided with a first connecting seat 127. One end of the second connecting arm 134 is rotationally connected with the corresponding first connecting seat 127. The other end of the second connecting arm 134 is rotationally connected with one end of the first connecting arm 132 away from the support plate 142. The support plate 142 is provided with a second connecting seat 146. One end of the first connecting arm 132 away from the second connecting arm 134 is rotationally connected with the support plate 142 through the second connecting seat 146.

[0047] Specifically, the first connecting arm 132 is rotationally connected with the second connecting arm 134, and the second connecting arm 134 is arranged on opposite sides of the first connecting arm 132. When the electronic device support 100 is folded, the first connecting arm 132 and the second connecting arm 134 are folded to be located on the same plane, which can maximize the compression of the occupied space of the folding arm assembly 130. In addition, the rotating assembly 120 is provided with a first connecting seat 127. One end of the second connecting arm 134 is rotationally connected with the corresponding first connecting seat 127, which can provide stable support while ensuring the rotation of the second connecting arm 134 relative to the rotating seat 121. One end of the first connecting arm 132 away from the second connecting arm 134 is rotationally connected with the support plate 142 through the second connecting seat 146, which can adjust the posture of the electronic device support 100, so that the support table 140 has more adjustable angles to meet different use requirements.

[0048] As shown in Figure 1 and Figure 3As shown, the support plate 142 is provided with a heat dissipation hole 1422, the end of the second extension arm 144 is provided with a limiting fold 1442, the first connecting arm 132 is provided with an avoiding hole 1322, when the electronic device support 100 is folded, the limiting fold 1442 can extend into the avoiding hole 1322 through the heat dissipation hole 1422.

[0049] Specifically, by the heat dissipation hole 1422 provided on the support plate 142, the heat dissipation of the electronic device can be avoided in the use state, so as to ensure the stability in the use state. In addition, the end of the first extension arm 114 is provided with the limiting fold 1442, which can limit the lower end of the electronic device, so as to avoid the electronic device from slipping off the support table 140. For example, the second extension arm 144 can be provided with four, the ends of the two second extension arms 144 located at the bottom are provided with the limiting fold 1442, and the other two second extension arms 144 are not required. In this way, when the electronic device support 100 is folded, the limiting fold 1442 can also extend into the avoiding hole 1322 through the heat dissipation hole 1422, which is beneficial to improve the compression rate after folding, so that the electronic device support 100 after folding is more compact, and is convenient to carry.
