[0017] Technical effects and advantages of the present invention:

[0018] 1.

At the same time, when the guide column is retracted into the movable seat, the conical seat simultaneously squeezes the push rod, that is, the squeezing thrust of the slide groove on the ball causes the ball at the end of the push rod to flip up, so that the other end of the arched push rod drives the clamping claw to squeeze the grille blades, thereby enhancing the squeezing force of the clamping claw on the air outlet blades and improving the anti-detachment stability.

[0019] 2. When the mobile phone of the present invention is placed on the bracket assembly, the pressure-bearing airbag will be compressed, so that the squeezing force of the limiting ball engaged in the universal ball head will increase, and the greater the weight of the mobile phone, the greater the squeezing force on the pressure-bearing airbag through the second slide frame, thereby more gas is introduced into the air storage bag through the air guide tube, and the squeezing force given to the guide cylinder after the air storage bag expands, which makes the compression of the support spring greater, thereby enhancing the stability of the limiting ball in the arc-shaped limiting groove, and utilizing the self-weight of the mobile phone after being placed on the bracket assembly to squeeze the pressure-bearing airbag, and then converting the gravity into the friction force between the universal ball head and the threaded seat, thereby enhancing the installation stability between the universal ball head and the threaded seat, preventing self-deviation after the mobile phone is placed on the bracket assembly, and ensuring that the bracket assembly can maintain the angle of the bracket assembly after the angle is adjusted, thereby improving stability.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] like Figures 1 to 10 As shown, the present embodiment discloses a mobile phone holder, including a holder assembly 10, wherein an adjusting assembly 20 for angle adjustment is mounted on the rear side wall of the holder assembly 10, and a clamping unit 30 is fixedly mounted on the rear end of the adjusting assembly 20, and the clamping unit 30 is mounted on the air outlet grille of the air conditioner, thereby greatly improving the installation stability. The driver can place the mobile phone on the holder assembly 10, and the angle (upward and downward inclination angles and left and right deflection angles) of the holder assembly 10 can be adjusted in real time through the adjusting assembly 20. At the same time, when the holder assembly 10 is used, the adjusting assembly 20 is used in conjunction with the use of the adjusting assembly 20 to ensure the angle limiting ability of the holder assembly 10 on the adjusting assembly 20, thereby preventing the holder assembly 10 from self-deviating and improving the installation stability.

[0034] The clamping unit 30 includes a fixed seat 31 installed on the adjustment assembly 20, a magnet ring 32 is fixedly installed on the end of the fixed seat 31, and the fixed seat 31 is magnetically assembled with a movable seat 34 through the magnet ring 32. The fixed seat 31 and the movable seat 34 are separated, which facilitates the disassembly and assembly of the movable seat 34 and improves the convenience of installation.

[0035] See also Figure 8-Figure 10The end of the movable seat 34 away from the fixed seat 31 is integrally formed with four groups of clamping claws 35 of the same structure, a limiting ring 36 is integrally formed on the inner wall of the movable seat 34, and a guide column 37 is movably assembled on the limiting ring 36. The end of the guide column 37 extends out of the movable seat 34, and a fixing ring 38 is fixedly sleeved on the outer wall of the guide column 37, and the fixing ring 38 is slidably assembled on the inner wall of the movable seat 34. A reset spring 39 is fixedly connected between the fixing ring 38 and the limiting ring 36, and the reset spring 39 is sleeved on the outer wall of the guide column 37. The other end of the guide column 37 is integrally formed with a conical seat 31 0, an arched push rod 312 is fixedly nested inside each set of clamping claws 35, and the other end of each set of push rods 312 is slidably assembled on the outer wall of the conical seat 310, each set of push rods 312 is bent outward to form an arched support rod, and the end of each set of push rods 312 is fixedly assembled with a ball 313, and a slide groove 311 matching the ball 313 is opened on the outer wall of the conical seat 310 along the generatrix direction, the bottom of the fixed seat 31 is in a sealed state, the movable seat 34 and the fixed seat 31 are both cylindrical, the interior of the movable seat 34 is hollow, and the size of the fixed ring 38 matches the size of the inner cavity of the movable seat 34.

[0036] When in use, the four groups of clamping claws 35 are engaged and assembled on the air outlet blades of the vehicle air-conditioning grille, and the clamping claws 35 are used to achieve preliminary limiting processing, and the movable seat 34 is installed on the air outlet blades, and the fixed seat 31 is magnetically installed on the movable seat 34 by using the magnet ring 32. The magnetic attraction force can prompt the fixed seat 31 to squeeze the guide post 37 so that it retracts into the movable seat 34, thereby utilizing the magnetic attraction force to overcome the resilience of the return spring 39 and retract into the movable seat 34, completing the installation of the fixed seat 31 and the movable seat 34. At the same time, when the guide post 37 retracts into the movable seat 34, the conical seat 310 synchronously squeezes the push rod 312, that is, the squeezing thrust of the slide groove 311 on the ball 313 prompts the ball 313 at the end of the push rod 312 to flip up, so that the other end of the arched push rod 312 drives the clamping claw 35 to squeeze the grille blades, thereby enhancing the squeezing force of the clamping claw 35 on the air outlet blades and improving the anti-detachment stability.

[0037] A limiting plate 33 is sleeved on the outer wall of the fixing seat 31, and the limiting plate 33 is a rubber plate, and a silicone pad is attached to the assembly of the limiting plate 33 and the fixing seat 31. When the clamping unit 30 is installed on the grille blade, the limiting plate 33 is moved on the fixing seat 31 so that the limiting plate 33 abuts against the outside of the grille blade to play a limiting role. When the mobile phone holder tilts downward due to gravity, the limiting plate 33 is used to abut against the vehicle grille to achieve limiting processing, thereby improving the installation stability of the mobile phone holder.

[0038] See also Figure 1-Figure 5A gear 11 is rotatably mounted in the middle of the bracket assembly 10 through a rotating shaft, and first slide frames 12 are slidably mounted on both sides of the bracket assembly 10, and first racks 13 meshing with the gear 11 are fixed on both sets of first slide frames 12, and transverse clamps 14 are fixed on the outer ends of both sets of first slide frames 12, and a second slide frame 15 is slidably mounted at the bottom of the bracket assembly 10, and a second rack 16 meshing with the gear 11 is fixed on the second slide frame 15, and a supporting claw 17 is provided at the bottom of the second slide frame 15. In actual use, when When the mobile phone is placed on the supporting claw 17, the weight of the mobile phone is used to squeeze the supporting claw 17, causing it to drive the second sliding frame 15 to move downward, and then synchronously drive the second rack 16 to drive the gear 11 to rotate. When the gear 11 rotates, it synchronously drives the first rack 13 to move, and then can drive the two groups of first sliding frames 12 to move synchronously towards each other, thereby driving the horizontal clamping claws 14 to clamp and limit the two sides of the mobile phone, so that the two groups of horizontal clamping claws 14 and the supporting claws 17 are used to achieve three-point limit of the mobile phone, thereby improving the stability of the mobile phone after installation.

[0039] It is worth mentioning that a clamping plate is slidably mounted on the surface of the transverse clamping jaw 14, and the surface of the clamping plate is wrapped with a plush cover, so that the clamping plate can move up and down on the transverse clamping jaw 14, which is convenient for changing the position of the clamped mobile phone by moving the clamping plate after the transverse clamping jaw 14 completes the clamping of the mobile phone. In this way, when the transverse clamping jaw 14 and the side button of the mobile phone coincide, the position of the clamping plate can be moved to effectively clamp the mobile phone.

[0040] See also Figure 4-Figure 8 The adjustment assembly 20 includes a threaded seat fixed on the rear side wall of the bracket assembly 10, and the threaded seat is composed of four groups of mounting units 21, and a universal ball head 22 is hingedly assembled in the threaded seat, and a locking ring 23 is sleeved on the outer side of the universal ball head 22, and the locking ring 23 is threadedly mounted on the threaded seat, and the universal ball head 22 is fixed to the end of the fixed seat 31, so that the universal ball head 22 is conveniently engaged in the threaded seat, and then threadedly mounted on the threaded seat through the locking ring 23, so as to enhance the friction between the universal ball head 22 and the threaded seat, and enhance the installation stability of the bracket assembly 10.

[0041] See also Figure 5-Figure 7Each group of mounting units 21 has a receiving groove inside, and an air storage bag 25 is installed in the receiving groove. A stepped groove 26 connected to the receiving groove is evenly opened on the inner wall of each group of mounting units 21, and a guide cylinder 27 is slidably installed in the stepped groove 26. A support spring 29 is fixedly connected in each group of guide cylinders 27. The other end of the support spring 29 extends out of the guide cylinder 27 and is fixedly connected to a limiting ball 28. The limiting ball 28 is slidably installed in the stepped groove 26. The air storage bag 25 abuts against the end of the guide cylinder 27. The universal ball head The outer wall of 22 is evenly provided with arc-shaped limit grooves 210 corresponding to the step grooves 26, the step grooves 26 include a guide hole connected to the accommodating groove, and the inner wall of the mounting unit 21 is provided with a circular groove connected to the guide hole, and the diameter of the circular groove is larger than the diameter of the guide hole, the guide cylinder 27 is slidably assembled in the guide hole, the limit ball 28 includes a mounting column slidably assembled in the circular groove, and the end of the mounting column is set to be hemispherical, and each group of limit balls 28 extends out of the circular groove and is limitedly plugged and assembled in the arc-shaped limit groove 210.

[0042] After the universal ball head 22 is assembled inside the threaded seat and locked by the locking ring 23, the limiting ball 28 is now engaged in the corresponding arc-shaped limiting groove 210, and the air storage bag 25 uses its own internal air pressure to give pressure to the guide cylinder 27, thereby ensuring that the support spring 29 gives the limiting ball 28 a pressure to engage in the arc-shaped limiting groove 210, thereby improving the installation stability. After the limiting ball 28 is engaged and assembled inside the arc-shaped limiting groove 210, a one-to-one correspondence between the limiting ball 28 and the arc-shaped limiting groove 210 can be achieved, and when the universal ball head 22 is in the threaded seat, the limiting ball 28 and the arc-shaped limiting groove 210 can be locked. When adjusting the angle in the threaded seat, the limiting ball 28 can be separated from one group of arc-shaped limiting grooves 210 and enter into another group of arc-shaped limiting grooves 210. The installation limiting property of the universal ball head 22 in the threaded seat is realized through the extrusion force of multiple groups of limiting balls 28 engaged inside the arc-shaped limiting grooves 210. The limiting ball 28 and the arc-shaped limiting grooves 210 at different positions are assembled to realize the adjustment of the angle of the bracket assembly 10. The locking ring 23 is used to complete the locking of the universal ball head 22 inside the threaded seat to ensure the stability of the bracket assembly 10.

[0043] Please note that, see Figure 3A downwardly disposed pressure-bearing airbag 24 is fixed on the top of the inner side wall of the second sliding frame 15, and the bottom end of the pressure-bearing airbag 24 is fixed on the inner side wall of the bracket assembly 10. When the mobile phone bracket is in use, the second sliding frame 15 moves downward to squeeze the pressure-bearing airbag 24, and the pressure-bearing airbag 24 is connected to the air storage bag 25 through the air guide tube, so that the gas inside the pressure-bearing airbag 24 will be introduced into the air storage bag 25 along the air guide tube, thereby increasing the gas pressure inside the air storage bag 25, so that the squeezing force of the air storage bag 25 on the guide cylinder 27 increases, thereby increasing the compression amount of the support spring 29, and then increasing the squeezing force of the limiting ball 28 through the support spring 29, thereby increasing the stability of the limiting ball 28 engaged in the arc-shaped limiting groove 210, and preventing the limiting ball 28 from detaching from the arc-shaped limiting groove 210.

[0044] It should be noted that each time a mobile phone is placed on the bracket assembly 10, the pressure-bearing airbag 24 will be compressed, so that the squeezing force of the limiting ball 28 engaged in the universal ball head 22 will increase, and the greater the weight of the mobile phone, the greater the squeezing force of the pressure-bearing airbag 24 through the second slide frame 15, so that more gas is introduced into the air storage bag 25 through the air guide tube, and the greater the squeezing force applied to the guide cylinder 27 after the air storage bag 25 expands, which makes the compression amount of the support spring 29 greater, thereby enhancing the stability of the limiting ball 28 in the arc-shaped limiting groove 210, and preventing the limiting ball 28 from being squeezed due to gravity when the weight of the mobile phone is too heavy. When the generated rotational torque is applied to the threaded seat, it will overcome the compression rebound force of the support spring 29 and make the limiting ball 28 disengage from the arc-shaped limiting groove 210. Therefore, the weight of the mobile phone after being placed on the bracket assembly 10 is used to squeeze the pressure airbag 24, and then the gravity is converted to act on the friction force between the universal ball head 22 and the threaded seat, thereby enhancing the installation stability between the universal ball head 22 and the threaded seat, preventing self-deviation after placing the mobile phone on the bracket assembly 10, and ensuring that the bracket assembly 10 can maintain the angle of the bracket assembly 10 after the angle is adjusted, thereby improving stability.

[0045] It should be noted that when the magnetic ring 32 is magnetically mounted on an iron plate, it can also be used to clamp a mobile phone, and has a wide range of applications. Only when used in a car, the clamping unit 30 needs to be used in conjunction with the adjustment component 20 to complete the use of the car-mounted mobile phone holder.

[0046] Embodiment 2

[0047] The present embodiment discloses a clamping mechanism, which includes an adjusting component 20 for adjusting the angle of a bracket assembly 10 and a clamping unit 30 installed on the air outlet grille of an air conditioner. The clamping unit 30 ensures the installation stability of the bracket assembly 10, and the adjusting component 20 ensures the stability of the bracket assembly 10 after the angle is adjusted. When the bracket assembly 10 is used, the adjusting component 20 is used in conjunction with the bracket assembly 10 to ensure the angle limiting ability of the bracket assembly 10 on the adjusting component 20, thereby preventing the bracket assembly 10 from self-deviating.

[0048] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
