[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figures 1 - 9 The present invention provides a technical solution: a foldable electronic communication equipment bracket, comprising a base 1, a foldable bracket 2 is fixedly connected to the top of the base 1, a placement table 3 is fixedly connected to one side of the foldable bracket 2, and an expansion function mechanism 4 is provided in the inner cavity of the base 1;

[0034] The expansion function mechanism 4 includes an expansion support unit 41, and the expansion support unit 41 is arranged in the inner cavity of the base 1;

[0035] The extended function mechanism 4 further includes a clamping and fixing unit 42, and the clamping and fixing unit 42 is arranged in the inner cavity of the base 1.

[0036] As a further limitation of the present invention, the extended support unit 41 includes a lead screw 4101 movably connected to the inner cavity of the base 1 through a bearing block. A nut sleeve 4102 is threadedly connected to the surface of the lead screw 4101. A support disc 4103 is fixedly connected to the surface of the nut sleeve 4102. A restraint frame 4104 is fixedly connected to the top of the support disc 4103. The number of the restraint frames 4104 is twelve. A scissor-type telescopic rod 4105 is movably connected to the inner cavity of the base 1. The scissor-type telescopic rods 4105 are in six groups, and the number of each group of scissor-type telescopic rods 4105 is two. A push plate 4106 is arranged in the inner cavity of the base 1. The number of the push plates 4106 is six. One side of each push plate 4106 is respectively movably connected to one end of the scissor-type telescopic rod 4105. One side of the push plate 4106 is slidably connected to a slider 4107. One side of the slider 4107 is movably connected to one end of the scissor-type telescopic rod 4105. One side of the scissor-type telescopic rod 4105 is fixedly connected to a restraint rod 4108. The inner wall of the push plate 4106 is fixedly connected to a fixed cylinder 4109. A first spring 4110 is sleeved on the surface of the fixed cylinder 4109. One end of the fixed cylinder 4109 penetrates through the base 1 and is fixedly connected to an extended frame 4111;

[0037] The number of the extended frames 4111 is six. One end of the first spring 4110 is fixedly connected to the inner cavity of the base 1, and the other end of the first spring 4110 is fixedly connected to one side of the push plate 4106. By setting the number of the extended frames 4111 to six, when the extended frames 4111 expand outward, a circumferential support effect can be achieved, which can increase the stability of the bracket. By setting the first spring 4110, the reset of the extended frames 4111 is ensured, the volume of the device in the storage state is reduced, and at the same time, by resetting the push plate 4106 to a specified position, the restraint rod 4108 and the restraint frame 4104 are on the same axis, which is convenient for driving the outward expansion of the extended frames 4111 next time;

[0038] The top of the lead screw 4101 penetrates through the base 1 and is fixedly connected to a driving knob 4112. Both sides of the push plate 4106 are provided with chutes, and the slider 4107 slides in the inner cavity of the chutes. By setting the driving knob 4112, the user manually rotates the driving knob 4112 to realize the extended support, clamping and fixing, and adaptive support functions of the bracket, and the operation is simple. By setting the chutes, it is convenient to limit the slider 4107, and it is convenient to restrain the scissor-type telescopic rod 4105 when it is compressed, ensuring its smoothness when compressed and improving the stability when the extended frame 4111 expands outward;

[0039] The clamping and fixing unit 42 includes a limiting rod 4201 fixedly connected to the inner cavity of the base 1. The number of the limiting rods 4201 is two. A second spring 4203 is sleeved on the surface of the limiting rod 4201. One end of the limiting rod 4201 is fixedly connected with a stop block 4204. A moving plate 4202 is arranged in the inner cavity of the base 1. The moving plate 4202 is slidably connected to the surface of the limiting rod 4201. A first through groove 4206 is formed in the top of the moving plate 4202. The number of the first through grooves 4206 is two. A fixing rod 4207 is fixedly connected to the inner cavity of the first through groove 4206. A connecting block 4208 is slidably sleeved on the surface of the fixing rod 4207. A fixing plate 4209 is fixedly connected to the top of the connecting block 4208. One side of the fixing plate 4209 is movably connected with a pressing rod 4205. The opposite ends of the two pressing rods 4205 are rotatably connected with a driving sleeve 4213. A third spring 4210 is fixedly connected to the bottom of the driving sleeve 4213. One end of the third spring 4210 is fixedly connected with the top of the moving plate 4202. A clamping block 4211 is fixedly connected to the bottom of the connecting block 4208;

[0040] A second through groove 4212 is formed in the bottom of the base 1. The elastic force of the third spring 4210 is greater than the sum of the elastic forces of the two second springs 4203. By providing the second through groove 4212, it is convenient for the clamping block 4211 to extend out, so that it is convenient to clamp the bracket to a fixed position. By setting the elastic force of the third spring 4210 to be greater than the sum of the elastic forces of the two second springs 4203, during the downward movement of the wire sleeve 4102, since the elastic force of the third spring 4210 is greater than the sum of the elastic forces of the two second springs 4203, the wire sleeve 4102 first drives the moving plate 4202 to move downward. When it contacts the bottom of the inner cavity of the base 1, the downward degree of freedom of the moving plate 4202 is limited, and then the wire sleeve 4102 drives the driving sleeve 4213 to move downward. The driving sleeve 4213 drives the connecting block 4208 to move through the pressing rod 4205 and the fixing plate 4209. The connecting block 4208 drives the clamping block 4211 to move inward, and the purpose of first extending the clamping block 4211 outward and then clamping it inward can be achieved;

[0041] One end of the second spring 4203 is fixedly connected with the top of the moving plate 4202, and the other end of the second spring 4203 is fixedly connected with the bottom of the stop block 4204. By providing the second spring 4203, after the wire sleeve 4102 is reset, through the action of the second spring 4203 on the moving plate 4202, the clamping block 4211 is reset, the bottom of the base 1 is made flat, and the stability of the bracket is ensured;

[0042] By setting the combined use of the expansion support unit 41 and the clamping and fixing unit 42, the purpose of making the device applicable to a variety of environments can be achieved without adding auxiliary tools. By increasing the support area, the overall stability of the base 1 can be increased. At the same time, the device can be fixed to the surface of an object in a suspended manner, increasing the scope of application.

[0043] The specific implementation of this embodiment is as follows: When it is necessary to increase the supporting area, manually rotate the driving knob 4112. The driving knob 4112 drives the lead screw 4101 to rotate. The lead screw 4101 drives the supporting disc 4103 to move upward through the lead screw sleeve 4102. The supporting disc 4103 drives the restraint frame 4104 to move. The restraint frame 4104 compresses the scissor telescopic rod 4105 through the restraint rod 4108. The scissor telescopic rod 4105 drives the expansion frame 4111 to move outward through the push plate 4106 and the fixed cylinder 4109, increasing the supporting area at the bottom of the bracket and ensuring the stability of the bracket. When storing, just rotate the driving knob 4112 in the reverse direction. The driving knob 4112 drives the supporting disc 4103 to move downward through the lead screw 4101 and the lead screw sleeve 4102. At this time, due to the action of the first spring 4110 on the push plate 4106, the push plate 4106 drives the expansion frame 4111 to reset through the fixed cylinder 4109, reducing the volume of the device in the storage state. At the same time, by resetting the push plate 4106 to the specified position, the restraint rod 4108 and the restraint frame 4104 are on the same axis, facilitating the outward expansion of the expansion frame 4111 next time. When it is necessary to fix this bracket at the vehicle air outlet, just manually rotate the driving knob 4112 in the reverse direction. The driving knob 4112 drives the lead screw sleeve 4102 to move downward through the lead screw 4101. During the downward movement of the lead screw sleeve 4102, since the elastic force of the third spring 4210 is greater than the sum of the elastic forces of the two second springs 4203, the lead screw sleeve 4102 first drives the moving plate 4202 to move downward. When it contacts the bottom of the inner cavity of the base 1, the downward degree of freedom of the moving plate 4202 is limited, exposing the clamping block 4211 to the outside. At this time, continue to rotate the driving knob 4112, and the lead screw sleeve 4102 continues to move downward. The lead screw sleeve 4102 drives the driving sleeve 4213 to move downward. The driving sleeve 4213 drives the connecting block 4208 to move through the pressure rod 4205 and the fixing plate 4209. The connecting block 4208 drives the clamping block 4211 to move inward, fixing this bracket at the baffle of the vehicle air outlet, and the purpose of first extending the clamping block 4211 outward and then clamping inward can be achieved. When storing, rotate the rotary button in the reverse direction. After the lead screw sleeve 4102 is reset, due to the action of the second spring 4203 on the moving plate 4202, the clamping block 4211 is reset, making the bottom of the base 1 flat and ensuring the stability of the bracket. Without the need to add auxiliary tools, the purpose of making this device applicable to various environments can be achieved.
