[0036] Embodiment 2

[0037] In actual applications, the existing mobile phone holder lacks a power structure to drive the clamps to clamp or loosen, and also lacks a sensing mechanism to control the movement of these power mechanisms, resulting in insufficient linkage performance and automation performance of the existing mobile phone holder. In addition, in the existing wireless charging mobile phone holder, the bracket position is not adjustable, resulting in only one size of mobile phone being placed between the bracket and the two clamps. When mobile phones of other sizes are placed in the mobile phone holder, the mobile phone charging area and the wireless charging module of the mobile phone holder will not be aligned, resulting in defects such as failure to charge or low charging efficiency, which is difficult to meet application requirements.

[0038] In order to solve the deficiencies in the prior art, this embodiment proposes a gravity sensing mechanism for a mobile phone holder, which is used to improve the linkage performance and automation performance of the mobile phone holder. Figures 1 to 8As shown, the mobile phone holder includes a shell 1, and two clamps 2 and a bracket 3 are provided on the side of the shell 1, and the bracket 3 and the two clamps 2 are distributed in a "pin" shape, and the two clamps 2 are respectively located on the left and right sides of the shell 1, and the clamp 2 is an "L"-shaped clamp including a horizontal support arm 20 and a vertical support arm 21. The horizontal support arms 20 of the two clamps 2 are respectively inserted on both sides of the shell 1, and the horizontal support arms 20 are slidably connected to the shell 1, and the bracket 3 includes a longitudinal support arm 30 and a support block 31 located at the lower end of the longitudinal support arm 30, and the upper end of the longitudinal support arm 3 is inserted in the shell 1, and it is characterized in that the shell 1 is provided with a device for driving the two clamps 2 to move away from or close to each other. A driving mechanism 4 is provided near the housing 1, a circuit board 5 is provided in the housing 1, the longitudinal arm 30 is located above the circuit board 5, and the longitudinal arm 3 can slide elastically up and down relative to the housing 1, a Hall element 50 is provided on the circuit board 5, a magnet 51 is provided above the Hall element 50, and the magnet 51 is driven to move by the longitudinal arm 3. When the mobile phone 100 is placed on the support block 31, the longitudinal arm 3 is driven to slide downward by the gravity of the mobile phone 100, and the magnet 51 and the Hall element 50 are relatively displaced to make the Hall element 50 output a control instruction, and the circuit board 5 controls the driving mechanism 4 to operate according to the control instruction to drive the two clamps 2 to clamp the mobile phone 100.

[0039] In the gravity sensing mechanism, a Hall element 50 is provided on the circuit board 5, and a magnet 51 is provided accordingly. When the mobile phone is placed on the bracket 3, the longitudinal arm 3 is driven by gravity to drive the magnet 51 to slide downward, so that the magnet 51 and the Hall element 50 are relatively displaced. The electrical signal output by the Hall element 50 is transmitted to the circuit board 5 as a control instruction, so that the circuit board 5 controls the operation of the driving mechanism 4, and then drives the two clamps 2 to clamp the mobile phone 100. Based on the above structure, the present invention realizes that the signal trigger can be realized while the mobile phone is placed, and the user does not need to operate other buttons. Compared with the prior art, the present invention greatly improves the linkage performance of the mobile phone holder, further improves the automation performance of the mobile phone holder, and better meets the needs of users and the market.

[0040] In order to enable the magnet 51 to move relative to the Hall element 50, in this embodiment, a fixed frame 8 is fixed in the shell 1, and a movable frame 9 is provided on the fixed frame 8, and the movable frame 9 can slide up and down relative to the fixed frame 8, the longitudinal support arm 3 is provided on the movable frame 9, and a support block 90 is formed at the upper end of the movable frame 9, and the magnet 51 is embedded in the bottom of the support block 90.

Among them, under the cooperation of the wavy teeth 31, the ball 92 and the second spring 93, the upper and lower positions of the longitudinal support arm 3 can be adjusted, and after the adjustment, the ball 92 and the second spring 93 are used to limit it to a preset position. Compared with the prior art, this embodiment can place various types of wireless charging mobile phones on the bracket 3. When the charging area of ​​the mobile phone is not aligned with the wireless charging module 60, it is only necessary to adjust the upper and lower positions of the longitudinal support arm 3 to achieve the alignment of the charging area of ​​the mobile phone with the wireless charging module 60. On the basis of ensuring the charging efficiency, the size compatibility of the mobile phone holder is greatly improved.

[0044] In order to limit the longitudinal support arm 3, in this embodiment, a slot hole 32 is opened on the longitudinal support arm 3, and the slot hole 32 extends along the length direction of the longitudinal support arm 3. A limiting screw 94 is provided on the movable frame 9, and the limiting screw 94 passes through the slot hole 32 and the two are slidably connected.

[0045] Embodiment 3

[0046] In actual applications, many mobile phone holders lack a power structure to drive the clamp to clamp or loosen, and also lack a sensing mechanism to control the movement of these power mechanisms, which makes it difficult to achieve manual control and insufficient automation performance. In addition, common power mechanisms are usually rigid drives. When they are applied to mobile phone holders, if the control circuit makes a misjudgment, the clamp is likely to over-clamp the phone, which will cause damage to the phone and pose many safety hazards.

[0047] In order to solve the above technical problems, this embodiment proposes a touch sensing mechanism for a mobile phone holder, which is used to improve the control performance and automation performance of the mobile phone holder.

The horizontal support arms 20 of the two clamps 2 are respectively inserted on both sides of the shell 1, and the horizontal support arms 20 are slidably connected to the shell 1, and the bracket 3 includes a longitudinal support arm 30 and a support block 31 located at the lower end of the longitudinal support arm 30, and the upper end of the longitudinal support arm 3 is inserted in the shell 1, and it is characterized in that the shell 1 is provided with a support block for driving the two A driving mechanism 4 is provided for moving the two clamps 2 away from or towards each other, a circuit board 5 is provided in the shell 1, a fixed frame 8 is fixed in the shell 1, a movable frame 9 is provided on the fixed frame 8, and the movable frame 9 can slide up and down relative to the fixed frame 8, the longitudinal support arm 3 is provided on the movable frame 9, a touch switch 82 is provided at the edge of the fixed frame 8, the touch switch 82 is penetrated through the side of the shell 1, the touch switch 82 is electrically connected to the circuit board 5, the touch switch 82 is used to input control instructions to the circuit board 5, and the circuit board 5 controls the operation of the driving mechanism 4 according to the control instructions to drive the two clamps 2 to clamp the mobile phone 100.

[0048] In the above touch sensing mechanism, a driving mechanism 4 is arranged in the housing 1, and a touch switch 82 is arranged on the side of the housing 1. When the user places the mobile phone between the two clamps 2, the user can touch the touch switch 82 with a finger, and the electrical signal output by the touch switch 82 is transmitted to the circuit board 5 as a control instruction. Then the circuit board 5 controls the driving mechanism 4 to operate according to the control instruction, thereby driving the two clamps 2 to clamp the mobile phone 100. Compared with the prior art, the present invention realizes the input of control instructions by touch, and realizes the automatic drive of the clamp 2, which greatly improves the control performance and automation performance of the mobile phone holder, and better meets the needs of users and the market.

[0049] In this embodiment, two touch switches 82 are disposed at the edge of the fixing frame 8 , and the two touch switches 82 are respectively disposed on two sides of the housing 1 .

[0050] In this embodiment, the driving mechanism 4 includes a gear box 41 and a motor 42. The gear box 41 includes an output gear 40. The output gear 40 passes through the gear box 41. A spur rack 22 is formed at the end of the lateral support arm 20. The spur racks 22 of the two lateral support arms 20 are respectively located on both sides of the output gear 40, and the two spur racks 22 are respectively meshed with the output gear 40. When the motor 42 is running, the output gear 40 is driven to rotate through the gear box 41 to drive the two chucks 2 to move away from or closer to each other.

[0052] In the above structure, since the third spring 48 is clamped between the fourth gear 46 and the shell 1, and the fourth gear 46 is meshed with the output gear 40 through the end face toothed disc 47, when the two clamps 2 clamp the mobile phone 100, if the motor 42 continues to run, the fourth gear 46 and the output gear 40 will overcome the elastic force of the third spring 48 and slide relative to each other, thereby eliminating a large driving force and effectively preventing the mobile phone 100 from being damaged due to excessive clamping force of the two clamps 2.
