Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] refer to Figures 1 to 12 :

[0031] This utility model patent discloses a waterproof electric mobile phone holder for outdoor use, including a clamping arm mechanism 100, a housing 200, and a motor 300. The clamping arm mechanism 100 includes a left clamping arm 1, a right clamping arm 2, and a base support 3. The base support 3 is located at the bottom of the housing 200. The left and right clamping arms 1 and 2 are located at the upper end of the housing 200 and can open and retract to clamp the mobile phone. The motor 300 is located inside the housing 200 and drives the left and right clamping arms 1 and 2 to perform clamping and releasing actions via a central gear 10 that rotates with its output end. One side of the housing 200 has a first through hole 201 and a first groove 202. Considering the difference from traditional electric mobile phone holders, here, the left and right clamping arms 1 and 2... When the guide rod of clamping arm 2 extends or retracts, it will bring in some water, causing water to enter the internal components. Here, the first waterproof rubber ring 41 is set in the first groove 202. The guide (guide rod) part of the left clamping arm 1 passes through the first waterproof rubber ring 41 and the first through hole 201. The other side of the housing 200 is provided with a second through hole 203 and a second groove 204. The second waterproof rubber ring 42 is set in the second groove 204. The guide part of the right clamping arm 2 passes through the second waterproof rubber ring 42 and the second through hole 203. As described above, the guide rod can still extend or retract because it has the through hole of the housing 200 as the first guide fulcrum and the first waterproof rubber ring 41 or the second waterproof rubber ring 42 as the second guide fulcrum.

[0032] Specifically, the left clamping arm 1 includes a first clamping arm 11, a first guide rod 12, and a first meshing member 13 that are fixedly connected to each other, wherein the first meshing member 13 is provided with a first guide tooth 131. The right clamping arm 2 includes a second clamping arm 21, a second guide rod 22, and a second meshing member 23 that are fixedly connected to each other, wherein the second meshing member 23 is provided with a second guide tooth 231. The second guide tooth 231 and the first guide tooth 131 mesh with the upper and lower ends of the central gear 10, respectively.

[0033] Specifically, the first guide rod 12 includes a first upper guide rod 121 and a first lower guide rod 122. One end of the first lower guide rod 122 is fixedly connected to the lower end of the first meshing member 13. A first linkage member 14 is also provided on one side of the first meshing member 13. One end of the first linkage member 14 is connected to the first meshing member 13, and the other end extends upward to the end of the first upper guide rod 121 and is fixedly connected thereto. The second guide rod 22 includes a second upper guide rod 221 and a second lower guide rod 222. One end of the second upper guide rod 221 is connected to the lower end of the second meshing member 23. The upper end is fixedly connected, and a second linkage 24 is also provided on one side of the second meshing member 23. One end of the second linkage 24 is connected to the second meshing member 23, and the other end extends downward to the end of the second upper guide rod 221 and is fixedly connected to it. This realizes the clamping arm mechanism 100 with four guide rods on both sides of the housing 200. The left clamping arm 1 and the right clamping arm 2 at both ends have two fulcrums on each guide rod through their respective double guide rod structures, and a total of four fulcrums each time. In this way, it is more stable during guidance, and each guide rod is provided with a waterproof rubber ring to achieve waterproofing.

[0034] Specifically, the upper end of the first linkage 14 is provided with a first guide groove 141 corresponding to the position of the second meshing member 23. On the one hand, it avoids the sliding of the second meshing member 23. On the other hand, the first guide groove 141 has a cross-sectional groove that matches the second meshing member 23. It can be nested around the outside of the second meshing member 23 to provide position guidance for the sliding of the second meshing member 23. The lower end of the second linkage 24 is provided with a second guide groove 241 corresponding to the position of the first meshing member 13, thereby avoiding the sliding of the first meshing member 13. This forms an inner and outer misalignment and an inner and outer ring-shaped sliding fit, making full use of the internal installation space of the housing 200, and the linkage between the two clamping arms is not prone to deviation.

[0035] Specifically, it also includes a limiting cover 5, which is disposed on the outside of the first gear 13 and the second gear 23. During installation, it is fixed to the internal structural components of the housing 200 by screws. The limiting cover 5 is provided with a central limiting hole 51, a first guide groove 52 and a second guide groove 53. The central limiting hole 51 is engaged with the end of the central gear 10. The outside of the first gear 13 is provided with a first guide block 132 and the outside of the second gear 23 is provided with a second guide block 232. The first guide block 132 passes through the second guide groove 53 for guidance and limitation, and the second guide block 232 passes through the first guide groove 52 for guidance and limitation. This limits the left and right sliding stroke of the first gear 13 and the second gear 23, that is, limits the clamping stroke of the outer left clamping arm 1 and the right clamping arm 2.

[0036] Specifically, the housing 200 includes a face cover 210 and a bottom shell 220. The bottom shell 220 has a recessed groove 221 at its annular connection. A waterproof adhesive strip 43 is embedded in the groove 221. Thus, the face cover 210 and the bottom shell 220, as the main components of the housing 200, can provide waterproofing at the joint of the face cover 210 and the bottom shell 220 through the annular waterproof adhesive strip 43. At the same time, the face cover 210 and the bottom shell 220 are also provided for easy assembly. The first through hole 201, the second through hole 203, the first groove 202 and the second groove 204, and the central gear 10 are all provided in the bottom shell 220.

[0037] Specifically, to reduce friction and isolate moisture when the guide rod extends and retracts, both the first waterproof rubber ring 41 and the second waterproof rubber ring 42 include a main ring body 410 and a buffer ring body 420 connected to each other. The main ring body 410 is cylindrical, and the buffer ring body 420 is flared. A buffer groove 401 is formed between the main ring body 410 and the buffer ring body 420. A buffer cavity 402 is formed on the inner side of the flared buffer ring body 420. The flared buffer ring body 420 is in close contact with the first through hole 201 or the second through hole 203 on the side of the housing 200. When moisture is brought in from the outside by the guide rod, it is first scraped off by the outside of the buffer ring body 420, so that the moisture is retained on the outside of the buffer cavity 402. On the other hand, the extension and retraction of the guide rod will create friction with the waterproof rubber ring. If a thicker waterproof rubber ring is used to fit the guide rod, the pulling force required for the operation of the motor 300 will need to be increased. However, the increased pulling force of the motor 300 will also require increased power, which is not conducive to the durability of the product, the battery life, and the control of later costs. Here, a buffer ring 420 is designed, which has a buffer groove 401 between it and the main ring 410. When the friction is high, the buffer ring 420 will be compressed inward by a small section. However, this small section will not cause water to enter the interior of the housing 200 through the gap of the buffer ring 420, because there is also the waterproof function of the first groove 202, the second groove 204, and the main ring 410.

[0038] Specifically, as part of daily waterproofing, this bracket also includes a battery. If the battery is charged using a traditional charging port, more waterproof structures need to be designed. Here, a solar panel 6 is provided on the faceplate 210 to supply power to the battery. A main control board 7 is provided on the inner side of the bottom shell 220. An adapter assembly 8 and a switch assembly 9 are provided on the back of the bottom shell 220. The adapter assembly 8 is preferably a ball joint adapter, or it can be connected to a vehicle-mounted fixed position by means of magnetic attraction, screw fixing, etc. The switch assembly 9 includes a switch sensor head 91, a switch button 92, and a switch base 93. The switch base 93 extends outward from one side of the back of the bottom shell 220. The inner side of the switch base 93 is recessed to form a first receiving cavity 931 with an outer opening. The shell of the bottom shell 220... A switch hole 222 communicating with the first accommodating cavity 931 is provided on the wall corresponding to the position of the first accommodating cavity 931. A trigger rod 921 is provided on the switch button 92 corresponding to the position of the switch hole 222. One end of the trigger rod 921 passes through the switch hole 222 and can abut against the switch sensor head 91. Pressing the switch button 92 can extend the trigger rod 921 into the housing 200 until it abuts against the switch sensor head 91, thereby triggering the switch of the main control board 7 to control the opening and closing of the left clamping arm 1 and the right clamping arm 2. On the other hand, the switch assembly 9 is set on the back of the bottom shell 220. When using the mobile phone holder, the front cover 210 is normally facing the user at a certain angle. Therefore, the part where the switch assembly 9 is located is facing downwards, forming a natural rainproof angle. So this has a dual technical effect.

[0039] Specifically, the inner side of the trigger rod 921 is provided with an anti-disengagement groove 921a, and an anti-disengagement component 921b is embedded in the anti-disengagement groove 921a. The anti-disengagement component 921b surrounds the anti-disengagement groove 921a, and the diameter of the anti-disengagement component 921b is larger than the diameter of the switch hole 222. Therefore, the trigger rod 921 cannot be pulled outward and can only remain inside the inner cavity of the housing 200. The inner side of the switch button 92 is also provided with a second receiving cavity 922, wherein the second receiving cavity 922 communicates with the first receiving cavity 931. A return spring 94 is also provided in the cavity 931 and the second accommodating cavity 922. The return spring 94 keeps the switch button 92 always outward. Only when the hand is pressed down will the trigger rod 921 in the switch button 92 be driven to touch the switch sensing head 91. The switch button 92 is also provided with an annular groove 923 on the inner wall of the switch base 93. A third waterproof rubber ring 44 is embedded in the annular groove 923. The third waterproof rubber ring 44 makes the pressing contact position between the switch button 92 and the switch base 93 form a waterproof structure.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
