Abstract
Description
Technical Field
[0001] This utility model relates to the field of mobile phone holder technology, specifically a mobile phone holder that is easy to fix. Background Technology
[0002] A car phone holder is a simple and easy-to-use phone holder that allows for the most comfortable use. It focuses on user experience and has an excellent structural design. Based on ergonomics and the human-machine design concept, it provides a better user experience for drivers.
[0003] Existing car phone holders are installed on car air conditioning vents and dashboards, mostly using two clamps to hold the air conditioning vent partition. These clamping mechanisms typically employ threaded rods to drive the clamps. When a vehicle travels on bumpy roads, vibrations are transmitted to the cabin via the suspension. These vibrations cause the clamps to vibrate. Because the threaded rod structure lacks a self-locking mechanism, continuous vibration can lead to three possible issues: First, vibration generates additional dynamic loads, subjecting the threaded connection to extra force, potentially causing loosening and wear on the threaded rod surface. Second, vibration causes minute relative movements on the thread surface, gradually wearing down the peaks and valleys of the thread, reducing friction and leading to loosening. Third, vibration can cause a resonance effect that gradually reduces the tightening force of the threaded connection. Therefore, a self-locking mechanism for the threaded rod is needed to improve the lifespan of the phone holder. In light of this, a phone holder designed for easy fixation is proposed.

[0031] Please see Figure 1-6 This utility model provides a new technical solution: a mobile phone holder that is easy to fix, including a base 1, a worm gear 2 rotatably connected to the inner wall of the base 1, the right end of the worm gear 2 penetrating through the right surface of the base 1, and a knob 3 fixedly installed on the right end of the worm gear 2.
[0032] The base 1 is equipped with a fixing mechanism, which includes a worm gear 4, a threaded rod 5, a movable plate 6, a first clamping plate 7, an anti-slip pad 8, a first support arm 9, a second support arm 10, a first slide groove 11, a sliding rod 12, a piston rod 13, a damper 14, a first spring 15, a back plate 16, four spring grooves 17, eight second springs 18, four L-shaped fixing plates 19, four second slide grooves 20, four third springs 21, and four second clamping plates 22.
[0033] Furthermore, the worm gear 4 is meshed with the outer surface of the worm 2, the threaded rod 5 is fixedly sleeved in the inner wall of the worm gear 4, the lower end of the threaded rod 5 is rotatably connected to the inner wall of the base 1, and the upper end of the threaded rod 5 extends through the upper surface of the base 1.
[0034] The movable plate 6 is threaded onto the outer surface of the threaded rod 5, the first clamping plate 7 is fixedly installed on the upper surface of the movable plate 6, and two anti-slip pads 8 are respectively fixedly installed on the opposite sides of the first clamping plate 7 and the base 1.
[0035] Furthermore, the first arm 9 is rotatably connected to the upper surface of the first clamping plate 7, and the two second arms 10 are rotatably sleeved on the outer surface of the first arm 9.
[0036] Two first grooves 11 are formed on the opposite sides of the two second arms 10, and the sliding rod 12 is slidably sleeved in the inner wall of the two first grooves 11.
[0037] Furthermore, the piston rod 13 is rotatably sleeved on the outer surface of the sliding rod 12, and the first spring 15 is fixedly installed on the lower surface of the piston rod 13;
[0038] The damper 14 is fixedly installed at the lower end of the first spring 15, and the damper 14 is slidably sleeved on the outer surface of the piston rod 13.
[0039] Furthermore, the back plate 16 is rotatably connected to the front ends of the two second arms 10, four spring grooves 17 are respectively opened on both sides of the back plate 16, and eight second springs 18 are respectively fixedly installed in the inner walls of the four spring grooves 17.
[0040] Furthermore, the vertical plates of the four L-shaped fixing plates 19 are respectively fixedly installed on the opposite ends of the eight second springs 18, and the vertical plates of the four L-shaped fixing plates 19 are respectively slidably connected to the four spring grooves 17.
[0041] Furthermore, four second slide grooves 20 are respectively opened on the opposite sides of the four L-shaped fixing plates 19, and four third springs 21 are respectively fixedly installed in the inner walls of the four second slide grooves 20.
[0042] Among them, the four second clamping plates 22 are respectively fixedly installed at the rear end of the four third springs 21, and the four second clamping plates 22 are respectively slidably connected to the four second sliding grooves 20.
[0043] When using this easy-to-fix mobile phone holder, the base 1 and the first clamping plate 7 are placed on both sides of the partition of the air conditioner vent. Rotating the knob 3 causes the worm gear 2 fixedly mounted on the left surface to rotate. The worm gear 2 drives the worm wheel 4 meshing with the outer surface to rotate, and the worm wheel 4 drives the threaded rod 5 fixedly sleeved on the inner surface to rotate. At this time, the moving plate 6, threaded on the outer surface of the threaded rod 5, continuously moves downwards through the threads on the outer surface of the threaded rod 5. The moving plate 6 then applies a downward pulling force to the first clamping plate 7 fixedly mounted on the upper surface. Meanwhile, the anti-locking mechanism fixedly mounted on the opposite side of the first clamping plate 7 and the base 1... The sliding pad 8 contacts the partition of the air conditioner vent to clamp and fix it. By placing the mobile phone on the upper surface of the horizontal plate of the L-shaped fixing plate 19, the mobile phone impacts the inclined surface of the second clamping plate 22. The second clamping plate 22 moves forward in the inner wall of the second sliding groove 20 under force. At the same time, the second clamping plate 22 applies pressure to the third spring 21, causing it to contract. The elastic potential energy of the third spring 21 itself applies a backward pushing force to the second clamping plate 22 to maintain the clamping force on the surface of the second clamping plate 22 to fix the mobile phone. At this time, a downward pressure is applied to the mobile phone, and the mobile phone presses against the L-shaped fixing plate 19. Applying downward pressure, the L-shaped fixing plate 19 slides downward in the spring groove 17. Simultaneously, the vertical plate of the L-shaped fixing plate 19 applies pressure to the second spring 18 fixedly mounted on the lower surface, causing it to contract. At this point, the L-shaped fixing plates 19 are pulled sequentially. By placing the phone between the four L-shaped fixing plates 19, no pulling force is applied to the L-shaped fixing plates 19, and the second spring 18 is no longer under force. The second spring 18 then expands, applying an upward pushing force to the vertical plate of the L-shaped fixing plate 19 fixedly mounted on the upper surface, causing it to move upward. At this time, the four L-shaped fixing plates 19 move towards... The relative surfaces move to fix the mobile phone. When the vehicle is bumpy, the damper 14 moves slowly upward on the outer surface of the piston rod 13. The damper 14 in this utility model is a hydraulic damper. The hydraulic damper consumes energy through damping oil and damping holes, thereby slowing down or stopping the mechanical movement process and thus forming a certain buffer. The damper 14 applies pressure to the first spring 15 fixedly installed on the upper surface, causing it to contract. The elastic potential energy of the first spring 15 itself forms a certain buffer. At this time, the movement amplitude of the two second arms 10 can be reduced, thereby reducing the shaking of the fixed mobile phone.
[0044] This easy-to-fix phone holder utilizes the self-locking property between the worm gear 2 and the worm wheel 4 to reduce the slight rotation of the threaded rod 5 due to vibration, thereby making the fixation between the first clamping plate 7 and the base 1 more secure and less prone to detachment. Furthermore, the anti-slip pad 8 fixedly installed on the opposite surfaces of the first clamping plate 7 and the base 1 provides a more stable fixation to the partition at the wet and slippery air conditioning vent, thus improving the overall stability of the phone holder. This easy-to-fix phone holder can reduce the movement amplitude of the second support rod through the damper 14, the first spring 15, and the piston rod 13, thereby reducing the vibration of the entire holder, improving the overall stability, and making it less prone to shaking. This makes the phone more stable when viewed, less prone to shaking, thus reducing dizziness and making the viewing experience more comfortable.
[0045] Working principle: When using this easy-to-fix mobile phone holder, the base 1 and the first clamping plate 7 are placed on both sides of the partition of the air conditioner vent. Rotating the knob 3 causes the worm gear 2 fixedly mounted on the left surface to rotate. The worm gear 2 drives the worm wheel 4 meshing with the outer surface to rotate. The worm wheel 4 drives the threaded rod 5 fixedly sleeved on the inner surface to rotate. At this time, the moving plate 6, threaded on the outer surface of the threaded rod 5, continuously moves downwards through the threads on the outer surface of the threaded rod 5. The moving plate 6 then applies a downward pulling force to the first clamping plate 7 fixedly mounted on the upper surface, thus fixing the first clamping plate 7 and the base 1 together. The installed anti-slip pad 8 contacts the partition of the air conditioner vent to clamp and fix it. By placing the mobile phone on the upper surface of the horizontal plate of the L-shaped fixing plate 19, the mobile phone impacts the inclined surface of the second clamping plate 22. The second clamping plate 22 moves forward in the inner wall of the second slide groove 20 under force. At the same time, the second clamping plate 22 applies pressure to the third spring 21, causing it to contract. The elastic potential energy of the third spring 21 itself applies a backward pushing force to the second clamping plate 22 to maintain the clamping force on the surface of the second clamping plate 22 to fix the mobile phone. At this time, a downward pressure is applied to the mobile phone, and the mobile phone presses against the L-shaped fixing plate. When downward pressure is applied to L-shaped fixing plates 19, they slide downward in spring grooves 17. Simultaneously, the vertical plate of the L-shaped fixing plate 19 applies pressure to the second spring 18 fixedly mounted on the lower surface, causing it to contract. At this point, the L-shaped fixing plates 19 are pulled sequentially. By placing the phone between the four L-shaped fixing plates 19, no further tension is applied to the L-shaped fixing plates 19, and the second spring 18 is no longer under force. The second spring 18 then expands, applying an upward pushing force to the vertical plate of the L-shaped fixing plate 19 fixedly mounted on the upper surface, causing it to move upward. At this time, the four L-shaped fixing plates 19... The phone is fixed by moving relative to each other. When the vehicle bumps, the damper 14 moves slowly upward on the outer surface of the piston rod 13. The damper 14 in this utility model is a hydraulic damper. The hydraulic damper consumes energy through damping oil and damping holes, thereby slowing down or stopping the mechanical movement process and thus forming a certain buffer. The damper 14 applies pressure to the first spring 15 fixedly installed on the upper surface, causing it to contract. The elastic potential energy of the first spring 15 itself forms a certain buffer. At this time, the movement amplitude of the two second arms 10 can be reduced, thereby reducing the shaking of the fixed phone.
