[0002] With the rapid development and popularization of smartphone technology, the demand for car phone holders as driving assistance equipment is growing in the market.

[0003] However, the existing car-mounted mobile phone holder mainly utilizes the linkage between two clamping plates and a supporting bracket to clamp the mobile phone. The user directly places the mobile phone on the supporting bracket and moves the supporting bracket downward, which can drive the left and right clamping plates to move inward to clamp the mobile phone. When the mobile phone needs to be taken out, the mobile phone is directly lifted up to move the supporting bracket upward, which can drive the left and right clamping plates to move outward to release the mobile phone. Although it can be used normally, there are many deficiencies in the clamping performance and stability, such as insufficient clamping force, unstable clamping, cumbersome operation, etc. These problems not only affect the driver's experience of use, but more importantly, may bring safety hazards, especially when the car is driving on complex road conditions (such as speed bumps, sudden brake impact, rugged mountain roads), it is more likely to cause the mobile phone to fall.

[0004] Therefore, the inventor is committed to designing a car-mounted mobile phone holder to solve the above problems. Utility Model Content

In this embodiment, a sliding surface 212 is also obliquely provided on the outer wall of the upper end of the support bracket 2, and the side of the slider 92 is inclined and slides against the sliding surface 212 of the support bracket 2.

[0036] Reference Figure 2 , Figure 5 and Figure 6 A button switch 8 is elastically inserted on the back of the base 11, and a switch spring 82 is arranged in the button switch 8. The button switch 8 is elastically connected to the cover plate 12 through the switch spring 82. A pressing boss 81 is arranged on the outer wall of the button switch 8. The pressing boss 81 is located in the shell assembly 1, and the bottom of the pressing boss 81 is inclined, that is, the pressing mating surfaces of the pressing boss 81 and the pressing groove 61 are both inclined, and the pressing groove 61 is located below the pressing boss 81. After the button switch 8 is pressed, it will automatically reset under the action of the switch spring 82, so that the pressing boss 81 is disengaged from the pressing groove 61, causing the locking block 6 to rotate at will. Therefore, the utility model arranges a plurality of card grooves 64 at intervals on the end surface of the locking block 6 away from the pawl 62.

[0037] Reference Figures 1 to 8 The working principle of the vehicle-mounted mobile phone holder with stable clamping performance of the utility model is:

[0038] Insert the mobile phone from top to bottom between the two clamping plates and supported by the support bracket 2. The support bracket 2 moves downward under the force of gravity from the mobile phone. On the one hand, the slider 92 on the latch 9 slides along the sliding surface 212 on the support bracket 2, and the latch 9 is inserted into the card slot 64 of the locking block 6, so that the locking block 6 can only rotate in one direction (counterclockwise). On the other hand, the inner rack 211 on the support bracket 2 drives the gear 5 to rotate clockwise, driving the left clamping plate 3 and the right clamping plate 4 to move inward laterally. At this time, the ratchet 51 rotates with the gear 5, and the pawl 62 engages with the ratchet 51 until the two clamping plates clamp the mobile phone. The ratchet 51 cannot be reversed and locks the support bracket 2 (such as Figure 7 As shown), the support bracket 2 cannot move upward;

[0039] When the mobile phone needs to be taken out, the button switch 8 is pressed first, the switch spring 82 is compressed, and the pressing boss 81 moves forward with the button switch 8 and moves into the pressing groove 61 of the locking block 6. The pressing boss 81 is tilted to press the pressing groove 61 of the locking block 6, forcing the locking block 6 to rotate around the fixed axis 112. On the one hand, the pressing spring 63 is compressed, and the pawl 62 is disengaged from the tooth groove on the ratchet 51 (such as Figure 8 As shown in the figure, the support bracket 2 is unlocked. On the other hand, the insertion end of the latch 9 is inserted into a card slot 64 above to lock the locking block 6 and prevent the locking block 6 from rotating in the opposite direction. At this time, the pawl 62 of the locking block 6 is disengaged from the ratchet 51, and the button switch 8 is released. The button switch 8 is reset under the action of the switch spring 82, so that the pressing boss 81 is disengaged from the pressing groove 61, and the support bracket 2 can move up and down, so that the mobile phone can be directly drawn out. During the process of drawing out the mobile phone, the gear 5 rotates counterclockwise, and the left clamping plate 3 and the right clamping plate 4 both move outward laterally, and the clamping distance between the two clamping plates becomes larger. At the same time, the support bracket 2 pushes the slider 92 to move outward, the side spring 91 is compressed, the latch 9 moves out of the card slot 64, and the locking block 6 is unlocked.

[0040] When the mobile phone needs to be put in again, the mobile phone is directly placed on the support bracket 2, and the support bracket 2 is moved down, and the latch 9 is inserted into the card slot 64 again, and the two clamps clamp the mobile phone again (repeat the above action).

[0041] The vehicle-mounted mobile phone holder with stable clamping performance of the utility model has two clamping plates and a support bracket 2 linked by a gear 5, so that the clamping plates and the support bracket 2 can act synchronously, realizing all-round clamping of the mobile phone, and through the rotation of the locking block 6, the pawl 62 at the end of the locking block 6 is meshed with the ratchet 51, and the support bracket 2 and the two clamping plates are firmly locked, realizing a high-precision clamping effect, and at the same time, the reverse clamping design of the ratchet 51 and the pawl 62 makes the clamping more accurate, stable, and not easy to loosen. The vehicle-mounted mobile phone holder of the utility model can place the mobile phone in a vertical screen or a horizontal screen, and realizes a stable clamping of the mobile phone through a unique mechanical structure and operating mechanism, with high precision, smoothness, and reverse clamping effects. It not only improves the user experience of the driver, but more importantly, it increases the safety of driving and provides a more convenient driving assistance tool for the driver.

[0042] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention.
