Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone holders for vehicles, and particularly to a vehicle-mounted holder. Background Art

[0002] As the current mainstream navigation device, smart phones have been widely used by drivers. Since the mobile phone needs to be placed in a position where the driver can see it at any time, mobile phone holders have emerged as the times require. Most of the current mobile phone holders on the market, especially those for two-wheeled or three-wheeled vehicles, in order to achieve the switching between the horizontal and vertical screens of the mobile phone, most of them need to unscrew the clamping nut during operation, and even need to use tools. Basically, both hands are required for operation. One hand holds the holder to fix the angle, and the other hand unscrews or tightens the screw lock to complete the adjustment action of rotating the holder angle. The operation is cumbersome. If the locking force is not enough, the angle of the mobile phone is likely to change during driving, affecting the use.

[0003] The utility model patent with the Chinese patent application number CN201820407225.2 discloses an outdoor mobile phone holder, which can solve the above problems through the design of several indexing teeth and elastic claws that can be engaged with the indexing teeth. However, the specific sliding inclined surface on the indexing teeth makes the stability effect of the above holder insufficient in one of the rotation directions. When encountering a large bump, the holder is likely to rotate in this direction, resulting in the user needing to manually turn back the angle of the holder, reducing the user experience.

[0004] Considering that some current mobile phone holders already have the function of automatic clamping, and the user does not need to manually operate the holder to clamp the mobile phone. When the mobile phone is placed well, pressing the switch to start the motor can clamp the mobile phone. Therefore, making the operation difficulty of the mobile phone holder lower and lower is in line with the development direction of the mobile phone holder for two-wheeled or three-wheeled vehicles. Therefore, this patent proposes a vehicle-mounted mobile phone holder with lower operation difficulty and better experience. Summary of the Invention

[0005] The purpose of the present invention is to solve the deficiencies existing in the prior art, and propose a vehicle-mounted holder, which can provide a good stepless rotation experience feedback to the user during rotation, allowing the user to easily operate and rotate the holder angle with one hand at any time, without the need for both hands and other cumbersome actions such as tools. Even when encountering a large bump, it will not rotate as in the existing adjustment methods, providing a better user experience. And after the mobile phone is placed well, it automatically controls the clamping component to clamp the mobile phone, making it more convenient for the user to use. Compared with other mechanical clamping methods, even when encountering large vibrations or impacts, it will not fall off, and the anti-vibration and anti-shock effects are remarkable.

[0012] Preferably, the wireless charging component includes a charging port, a PCB board, a coil and a panel; the charging port is embedded in the side of the main body; the coil is used for charging and detecting foreign objects.

[0013] Preferably, the output end of the wireless charging component is connected to the input end of the main control chip, so as to realize automatic clamping immediately after the electronic navigation device is placed properly.

[0014] Preferably, the automatic clamping component includes two clamping arms for clamping the side of the electronic navigation device and a driving mechanism for driving the clamping arms to move away from or close to the main body.

[0015] Preferably, the driving mechanism includes a connecting rod, a screw rod fixedly installed on the side of the clamping arm close to the main body and slidably matched with the side of the main body, and a motor for driving the screw rod to rotate. The motor drives the screw rod to rotate to realize the movement of the clamping arm, so as to realize the clamping and loosening of the electronic navigation device.

[0016] Preferably, the screw rod is in threaded cooperation with the clamping arm and can pass through the clamping arm.

Through the circuit design of the wireless charging component, the main control chip, and the automatic clamping component, it is possible to automatically control the clamping part to clamp the mobile phone by detecting the foreign object detection function of the coil after the mobile phone is placed, making it more convenient for the user to use.

[0023] 3. The motor drives the screw rod to drive the clamping arm to clamp the mobile phone. When the motor does not work in the clamping state, since only the rotation of the screw rod can drive the movement of the clamping arm, and the movement of the clamping arm cannot drive the screw rod and the motor to rotate in reverse, external forces cannot cause the clamping arm to open. Compared with other mechanical clamping methods, the mobile phone can be locked better, preventing the mobile phone from falling off. Even when encountering large vibrations or impacts, it will not fall off, and the anti-vibration and anti-shock effects are remarkable. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0031] Please refer to Figure 1-2 , the present invention provides the following technical solutions: A vehicle-mounted bracket includes a clamp 1, a base 2 and a clamping member 3. The clamp 1 is used to install the present bracket on a vehicle, such as a handlebar, the front of a vehicle, etc.; the base 2 is rotationally connected to the front end of the clamp 1 through a stepless rotation structure 4; the clamping member 3 is fixedly connected to the front end of the base 2 and is used to clamp an electronic navigation device; the stepless rotation structure 4 includes a main shaft 5, a gear 6, a positioning valve 7 and rubber rings 8 distributed on the front and back of the gear 6. By the combined use of the gear 6 and the positioning valve 7, the functions of rotation and locking are realized. Then, through the rubber rings 8 distributed at both ends of the gear 6, a good damping feeling and full support can be provided during rotation, so as to provide a good stepless rotation experience feedback to the user, allowing the user to easily operate the rotation angle of the bracket with one hand at any time without cumbersome actions such as using both hands and tools.

[0032] Such as Figure 1 And Figure 2As shown, a central groove 9 for the main shaft 5 to pass through is provided in the front cavity of the base 2. The positioning valve 7 is slidably connected in the cavity of the base 2 and is located on the side of the central groove 9. The sliding of the positioning valve 7 can loosen or lock the gear 6, enabling the base 2 to rotate freely around the gear 6 and be locked at an angle, allowing the user's electronic navigation device such as a mobile phone to be adjusted to landscape or portrait to display map information for viewing. And there are no less than two groups of positioning valves 7, which are evenly distributed according to the center line of the gear 6, so that when encountering a large bump, there will be no rotation as in the existing adjustment methods, providing a better user experience. The positioning valve 7 includes a positioning tooth near one end that cooperates with the gear 6 and an elastic structure 10 that can return to its original state after the external force at the other end disappears. Among them: the positioning tooth that cooperates with the gear 6 can prevent the adjusted base 2 from radially shaking on the clamp 1; the elastic structure 10 can be a spring, a spring sheet, an elastic body material, etc., which can return to its original state after removing the external force; and the elastic structure 10 is in a compressed state when the positioning valve 7 completely enters the tooth groove on the gear 6. When the user needs to adjust to landscape or portrait display, the mobile phone can be directly rotated to retract the elastic structure 10, so that the adjustment can be directly carried out. When the adjustment is completed, the elastic structure 10 can directly pop out to make the positioning tooth lock the gear 6, thus realizing the locking of the display angle of the mobile phone. A baffle 11 is fixedly installed in the cavity of the base 2 and in front of the gear 6. The baffle 11 and the front end of the central groove 9 limit the gear 6 in the base 2 through a rubber ring 8; the main shaft 5 passes through the central groove 9 and the central hole of the gear 6 in sequence from the rear of the base 2 and is fixedly installed through a screw 12 and a gasket. The central hole of the gear 6 and the front end of the main shaft 5 are both set in a shape such as a square that will not slip radially after assembly, so that after the main shaft 5 and the gear 6 are fixed, the gear 6 remains radially stationary, while the base 2 can rotate around the gear 6.

[0033] As Figure 1 , Figure 4 and Figure 5As shown in the figure, the clamping component 3 includes a main body 13, an automatic clamping assembly 14, a wireless charging assembly 15, a main control chip and buttons 16, where: The main body 13 is threadedly connected to the base 2, so that the clamping component 3 rotates together with the base 2; The automatic clamping assembly 14 is used to automatically clamp the electronic navigation device; The wireless charging assembly 15 is fixedly connected inside the main body 13 and is located in front of the automatic clamping assembly 14, and is used to wirelessly charge the mobile phone clamped by the automatic clamping assembly 14. The wireless charging method is more convenient for users to place and take at will, and there is no need to plug in the charging cable to charge, saving time; The main control chip is used to control the operation of the automatic clamping assembly 14; Two buttons 16 are provided, and the output ends of the left and right buttons 16 are both controlled to connect to the input end of the main control chip to control the automatic clamping assembly 14 to release the mobile phone, so that the user can take out the mobile phone. The left and right buttons 16 are also more convenient to match the habits of the driver, and both the left and right hands can be used for operation. The wireless charging assembly 15 includes a charging port 17, a PCB board 18, a coil 19 and a panel 20. Among them, the charging port 17 adopts a conventional Android or TYPE-C socket, which can be used for mobile devices to charge, facilitating users to choose the wired charging method for charging. The charging port 17 is embedded in the side of the main body 13; The coil 19 is used for charging and detecting foreign objects. The output end of the wireless charging assembly 15 is connected to the input end of the main control chip, so that after the electronic navigation device is placed, the foreign object detection function of the coil 19 detects that the mobile phone is placed in place and then transmits the signal to the main control chip to control the automatic clamping assembly 14 to automatically clamp the mobile phone radially, making it more convenient for users to use. The automatic clamping assembly 14 includes two clamping arms 21 for clamping the side of the electronic navigation device and a driving mechanism for driving the clamping arms 21 to move away from or close to the main body 13. The driving mechanism includes a connecting rod 22 fixedly installed on the side of the clamping arm 21 close to the main body 13 and slidably matched with the side of the main body 13, a screw rod 23 and a motor 24 for driving the screw rod 23 to rotate. Among them, the connecting rod 22 slides inside the main body 13 to make the movement of the clamping arm 21 more stable. The setting of the screw rod 23 makes the automatic clamping assembly 14 can only be driven by the motor 24 to rotate the screw rod 23 to actively drive the clamping arm 21 to move, and cannot be driven by the movement of the clamping arm 21 to rotate the screw rod 23. Therefore, the clamping component 3 will not be displaced when encountering bumps, and has good stability, which can ensure that the mobile phone is firmly clamped by this bracket during the driving of the vehicle under bad road conditions and there is no risk of falling off, avoiding the situation of the mobile phone falling and being damaged or even the occurrence of traffic safety accidents.The motor 24 drives the screw 23 to rotate to realize the movement of the clamping arm 21, thereby realizing the clamping and loosening of the electronic navigation device. The motor 24 can be a stepper motor or a servo motor. By calculating the difference between the maximum distance and the minimum distance of the two clamping arms 21 through the encoder, the number of turns that the screw 23 needs to rotate is determined, and thus the number of turns that the motor 24 needs to rotate is determined. And compared with other mechanical clamping methods, the method of using the motor 24 to drive the screw 23 to drive the clamping arm 21 to clamp the mobile phone is adopted. When the motor 24 does not work in the clamping state, since only the rotation of the screw 23 can drive the clamping arm 21 to move, and the movement of the clamping arm 21 cannot drive the screw 23 and the motor 24 to rotate in reverse, the external force cannot make the clamping arm 21 open, so the mobile phone can be better locked to prevent the mobile phone from falling off, and it will not fall off even when encountering large vibrations or even impacts, and the anti-vibration and anti-shock effects are remarkable.

[0034] As Figure 4 shown, the screw 23 is in threaded fit with the clamping arm 21 and can pass through the clamping arm 21, so that the connecting rod 22 can prevent the clamping arm 21 from rotating with the screw 23 at the same time, so that when the screw 23 rotates, it drives the clamping arm 21 to move.

[0035] As Figure 3 shown, the driving mechanism further includes a transmission rod 25 fixedly connected to one side of the clamping arm 21 close to the main body 13 and a slider 26 fixedly connected to one end of the transmission rod 25; the slider 26 is in threaded fit with the screw 23, the transmission rod 25 is inserted into the side wall of the main body 13 and is fixedly connected to the slider 26 by threads, and a guide rod 27 matched with the slider 26 is fixedly installed in the cavity of the main body 13, and the guide rod 27 is parallel to the moving direction of the slider 26. The guide rod 27 prevents the slider 26 from rotating with the screw 23, so that the slider 26 moves along the length direction of the guide rod 27, so that the transmission rod 25 fixedly connected to the slider 26 moves together, so as to drive the clamping arm 21 to clamp or loosen the mobile phone.

[0036] As Figure 3 With Figure 4 shown, one of the clamping arms 21 is fixedly connected to one side of the main body 13, and the two clamping arms 21 are symmetrically distributed with respect to the rotation plane of the screw 23.

[0037] As Figure 1 shown, the clamp 1 is fixedly connected to the rear end of the main shaft 5.

[0038] The working principle and usage process of the present invention are as follows: the mobile phone is placed in the clamping component 3, with the back of the mobile phone against the panel 20. After the foreign object detection function of the coil 19 detects that the mobile phone is placed properly, it transmits a signal to the main control chip, causing the motor 24 to drive the screw 23 to rotate, so that the automatic clamping component 14 automatically runs to clamp the mobile phone and wirelessly charge the mobile phone. Compared with the existing method that requires pressing the start button to clamp the mobile phone, it is more convenient to use and the user can put the mobile phone with one hand. After the user plans and sets the navigation route, the clamping component 3 can be rotated to put the mobile phone in landscape, portrait or viewing angle suitable for the user. Since the gear 6 and the positioning valve 7 cooperate to realize the rotation and locking functions, and the rubber rings 8 distributed at both ends of the gear 6 can provide a good damping feeling and full support during rotation, thereby providing a good stepless rotation experience feedback to the user, allowing the user to easily operate the angle of the bracket with one hand at any time, without the need for two-hand operation and tools and other tedious actions. Since the positioning teeth at the front end of the positioning valve 7 in the stepless rotation structure 4 cooperate with the gear 6, the adjusted bracket is not prone to radial shaking on the clamp 1. Even when encountering large bumps, it will not rotate like in the existing adjustment method, giving the user a better experience.

[0039] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
