[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0049] The adjusting mechanism provided in the embodiments of the present application is applied to an electronic device support, and the adjusting mechanism comprises: a first rotating arm 10, an adjusting seat 20 and a second rotating arm 30 which are sequentially rotationally connected, and the specific structure can be referred to Figure 1 and Figure 4 ;

[0050] A first end of the first rotating arm 10 is used for connecting an electronic device placing rack 40, and a second end of the second rotating arm 30 is used for rotationally connecting a base;

[0051] The adjusting seat 20 comprises a first clamping piece 21, an adjusting assembly 22 and a second clamping piece 23, as shown in Figure 2 The adjusting assembly 22 comprises a locking piece 221 and an elastic piece 222, as shown in Figure 9

[0052] The first clamping piece 21 is provided with a fastening cavity 211 on the side facing the second clamping piece 23, the fastening cavity 211 being a through structure along its axial direction, as shown in Figure 3 The second clamping piece 23 is provided with a fastening piece 231 on the side facing the first clamping piece 21, as shown in Figure 8

[0053] The locking piece 221 is threadedly engaged with the fastening piece 231 passing through the fastening cavity 211 to provide a locking force to lock the first clamping piece 21 and the second clamping piece 23; the first end of the elastic piece 222 is connected to the locking piece 221, and the second end of the elastic piece 222 is connected to the first clamping piece 21 to provide an elastic restoring force to the locking piece 221; the elastic restoring force is opposite to the locking force.

[0054] In the above technical solution, the locking piece 221 is threadedly engaged with the fastening piece 231 to convert the rotational movement of the locking piece 221 into the linear movement of the locking piece 221 along the axial direction of the fastening piece 231 through a screw transmission pair; when it is needed to lock the first clamping piece 21 and the second clamping piece 23, the locking piece 221 is rotated in a first direction to provide a locking force to lock the two clamping pieces; when it is needed to release the first clamping piece 21 and the second clamping piece 23, the locking piece 221 is rotated in a second direction to release the two clamping pieces, wherein the first direction and the second direction are opposite (if the first direction is clockwise rotation, the second direction is counterclockwise rotation, and vice versa); in the locking process, the elastic piece is compressed to store elastic potential energy (i.e. the elastic restoring force), so that the first clamping piece 21 and the second clamping piece 23 are not immediately separated during the release process of the first clamping piece 21 and the second clamping piece 23 when the locking piece 221 is rotated in the second direction; at the same time, the thread engagement between the locking piece 221 and the fastening piece 231 also makes the first clamping piece 21 and the second clamping piece 23 always in a relatively close state, and prevents the clamping pieces and the first rotating arm 10 and the second rotating arm 30 from being separated; wherein the clamping pieces include the first clamping piece 21 and the second clamping piece 23.

[0055] The above technical solution is optimized, as shown in Figure 5 ​​As shown, the locking member 221 is a knob, and the fastener 231 is a bolt or a screw, wherein the head of the bolt or the head of the screw is fixed to the second clamping member 23, and the threaded end of the bolt or the threaded end of the screw is screwed with the knob; in use, if the fastener 231 is a bolt, the threaded end of the bolt is screwed with the knob, and if the fastener 231 is a screw, the threaded end of the screw is screwed with the knob; the cooperation of the knob with the bolt or the screw can quickly realize the locking and releasing of the first clamping member 21 and the second clamping member 23.

[0056] In an optional embodiment, as shown in Figure 6 the elastic member 222 is a compression spring, which can well provide elastic restoring force as a mature component in actual application, and has good fatigue resistance (can withstand million times of compression cycles) and stability, which is beneficial to prolong the service life of the adjusting mechanism.

[0057] To optimize the above technical solution, the first end of the compression spring is in abutment with the locking member 221, and the second end of the compression spring is in abutment with the first clamping member 21; in use, in order to lock the first clamping member 21 and the second clamping member 23, the locking member 221 is screwed downward (the downward direction is the downward direction of Figure 5 ), so that the compression spring is deformed to generate elastic restoring force.

[0058] In an optional embodiment, in order to reduce the assembly process of the adjusting mechanism and save time, the first end of the compression spring is fixedly connected with the locking member 221.

[0059] To optimize the above technical solution, the first end of the compression spring is integrally formed with the locking member 221, which can effectively avoid the breakage of the compression spring and the locking member 221, and is beneficial to prolong the service life of the adjusting mechanism.

[0060] In an optional embodiment, as shown in Figure 6 and Figure 9 the lower end wall of the fastening cavity 211 is folded towards the axis to form an annular edge 212;

[0061] the locking member 221 is a knob, and the elastic member 222 is a compression spring;

[0062] the bottom surface of the knob has a locking rod 2211 extending away from the top surface of the knob, and the inside of the locking rod 2211 is a threaded hole 2212; the threaded hole 2212 is screwed with the threaded end of the fastener 231 passing through the through hole of the annular edge 212, and the fastener 231 is sleeved in the inner cavity of the compression spring;

[0063] the first end of the compression spring is connected with the locking rod 2211, and the second end of the elastic member 222 is in abutment with the upper end surface of the annular edge 212.

[0064] In the technical solution, the upper end surface of the annular side 212 serves as a support surface of the elastic member 222. When the knob is rotated downward (the downward direction is the downward direction of the arrow Figure 6 , the first clamping member 21 and the second clamping member 23 are in close contact with each other; when the knob is rotated upward (the upward direction is the upward direction of the arrow Figure 6 , the elastic restoring force provided by the compression spring prevents the first clamping member 21 and the second clamping member 23 from being immediately separated.

[0065] The above technical solution is optimized. As shown in Figure 6 , the threaded hole 2212 is a stepped through hole. The upper hole 2213 of the threaded hole 2212 has a larger inner diameter than the lower hole 2214. A thread is arranged in the lower hole 2214 and is screwed with the locking rod 2211. The upper hole 2213 and the lower hole 2214 are connected by a limiting stepped surface 2215.

[0066] The upper end of the fastener 231 is provided with a limiting member 232 matched with the limiting stepped surface 2215, so as to limit the upper end of the fastener 231 in the upper hole 2213.

[0067] In the above solution, the cooperation of the limiting member 232 and the limiting stepped surface 2215 prevents the fastener 231 from being over-screwed and separated from the knob. As an optimization, the middle position of the top surface of the knob is an opening (which is communicated with the threaded hole 2212). The knob has a knob cover plate for covering the opening. The limiting member 232 can enter the threaded hole 223 through the opening and be screwed with the fastener 231.

[0068] The above technical solution is further optimized. As shown in Figure 6 , the limiting member 232 has a circular structure, and the diameter of the circular structure is between the diameters of the upper hole 2213 and the lower hole 2214. Specifically, the upper end surface of the limiting member 232 is provided with a circular structure (such as a circular cap or a circular table). The lower end of the limiting member 232 is a limiting connecting rod which is screwed with the fastener 231. The upper end of the fastener 231 is provided with a through hole matched with the limiting connecting rod. As an optimization, the limiting connecting rod and the fastener 231 are coaxially arranged, as shown in Figure 6 . It should be noted that the elastic restoring force provided by the compression spring prevents the first clamping member 21 and the second clamping member 23 from being separated as independent components, thereby preventing the clamping member and the first rotating arm 10 and the second rotating arm 30 from being separated. Specifically, the first universal ball head 11 of the first rotating arm 10 and the second universal ball head 31 of the second rotating arm 30 are prevented from falling off from the middle ball cavity of the adjusting mechanism. The limiting member 232 further prevents the universal ball heads from falling off from the middle ball cavity of the adjusting mechanism.

[0069] In an optional embodiment, as shown in Figures 7-9As shown, both the first clamping member 21 and the second clamping member 23 are elongated structures;

[0070] like Figure 2 As shown, in order to solve the problem of the difficulty in adjusting the angle of the electronic device bracket, the second end of the first rotating arm 10 is the first universal ball joint 11, and the first end and the second end of the second rotating arm 30 are the second universal ball joint 31 and the third universal ball joint 32, respectively.

[0071] A first ball cavity is formed between the first end of the first clamping member 21 and the first end of the second clamping member 23, and a second ball cavity is formed between the second end of the first clamping member 21 and the second end of the second clamping member 23.

[0072] Among them, the first universal ball joint 11 is rotatably connected to the first ball cavity, the second universal ball joint 31 is rotatably connected to the second ball cavity, and the third universal ball joint 32 is rotatably connected to the base.

[0073] In the above technical solution, the use of the universal ball joint and the ball cavity can adjust the angle required by the user, thereby improving the user experience.

[0074] In optimizing the above technical solution, in order to further improve the user experience, the connection between the first end of the first rotating arm 10 and the electronic device placement rack is a rotatable connection. Specifically, the first end of the first rotating arm 10 is a fourth universal ball joint, which is rotatably connected to the electronic device placement rack.

[0075] This utility model also provides an electronic device bracket, including: an electronic device placement rack and a base, and further including: the adjustment mechanism as described above. Since this solution employs the aforementioned adjustment mechanism, it has corresponding beneficial effects, which can be referred to the preceding description and will not be repeated here.

[0076] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0077] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
