Description

Technical Field

[0001] This utility model belongs to the field of vehicle mobile phone holder technology, and in particular relates to a quick disassembly device for vehicle mobile phone holders. Background Technology

[0002] In modern driving, car phone holders have become an indispensable tool for many car owners. They can securely fix the phone in a specific position inside the car, bringing great convenience to the driver when using navigation, answering calls, and other operations. Among them, adhesive car phone holders use double-sided adhesive to fix the holder to a smooth surface inside the car.

[0003] However, some existing adhesive car phone holders leave residue of double-sided adhesive that is difficult to clean when disassembling. This requires the use of organic solvents or tools to scrape it off, which is not only time-consuming and laborious, but also easily damages the car's surface and makes it difficult to quickly disassemble the holder. Moreover, as the usage time increases, the adhesive strength of the double-sided adhesive decreases, and the holder is prone to falling off, failing to guarantee stable support. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release device for a car phone holder. It incorporates a sealing component and a ventilation component. Specifically, when the button is pressed, it moves the connecting rod to the left, pushing the sealing block away from the ventilation groove. This allows external air to quickly enter the base and suction cup through the ventilation pipe and ventilation groove, balancing the air pressure and eliminating the suction force. Disassembly can be completed with just one-handed pressing, greatly improving ease of operation, reducing disassembly difficulty and time costs, meeting the needs of quick removal and placement in car scenarios, and enhancing the user experience. This invention also solves the problem of existing adhesive car phone holders where double-sided adhesive residue is difficult to clean during disassembly, requiring the use of organic solvents or tools for scraping, which is not only time-consuming and laborious but also easily damages the vehicle surface, making quick disassembly difficult.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a quick-release device for a car phone holder, comprising a base, a suction cup mounted on the bottom of the base, a bracket mounted on the top of the base, and a communicating groove between the base and the suction cup, and further comprising: A disassembly mechanism is installed inside the base. The disassembly mechanism is used to break the negative pressure inside the suction cup, thereby quickly disassembling the entire device. The disassembly mechanism eliminates the suction cup's adsorption capacity by balancing the air pressure inside and outside the suction cup, thereby allowing for quick disassembly of the base and bracket from their installation position inside the vehicle.

[0006] Furthermore, the disassembly mechanism includes a sealing assembly mounted on the outside of the base, the sealing assembly being used to prevent air pressure leakage from the suction cup and the inside of the base; and A ventilation component is installed inside the base. The ventilation component is used to disrupt the sealing effect of the sealing component, thereby allowing the gas inside the base and suction cup to communicate with the external gas. A reset component is installed inside the base and is used to restore the sealing effect of the sealing component after the venting component damages the sealing effect of the sealing component. A reinforcing component is installed inside the suction cup and is used to generate a pre-tightening force on the edge of the suction cup, so that the edge of the suction cup adheres more tightly to the surface being adsorbed.

[0007] The sealing assembly, ventilation assembly, and reset assembly are used to quickly eliminate the suction cup's adsorption capacity and quickly disassemble the bracket, while the reinforcement assembly is used to enhance the suction cup's adsorption effect. Furthermore, the sealing assembly includes a vent pipe fixedly connected to the outer wall of the base, the vent pipe communicating with the interior of the base, a fixing block fixedly connected to the inner wall of the vent pipe, a vent groove formed on the inner wall of the fixing block, and a sealing block slidably connected to the inner wall of the vent groove. The larger end of both the venting groove and the sealing block is far from the base.

[0008] Furthermore, the ventilation assembly includes a fixed plate fixedly connected to the inner top wall of the base, a connecting rod fixedly connected to the right end of the sealing block, the right end of the connecting rod passing through the fixed plate and extending to the outside of the base, the connecting rod being slidably connected to the fixed plate and the base respectively, and a button fixedly connected to the right end of the connecting rod. The fixing plate is fixedly connected to the inner top wall of the base by welding.

[0009] Furthermore, the reset assembly includes a connecting ring fixedly connected to the outer wall of the connecting rod, and a spring is sleeved on the outer wall of the connecting rod; The connecting ring is fixedly connected to the connecting rod by welding.

[0010] Furthermore, the reinforcing component includes a mounting groove formed inside the suction cup, and a memory metal ring is installed on the inner wall of the mounting groove; The mounting slot is adapted to the shape memory metal ring.

[0011] This utility model has the following beneficial effects: 1. By setting up sealing and ventilation components, specifically when the button is pressed, the button moves the connecting rod to the left, pushing the sealing block away from the ventilation groove, allowing external air to quickly enter the base and suction cup through the ventilation pipe and ventilation groove, balancing the air pressure and eliminating the suction force. Disassembly can be completed with just one-handed pressing, greatly improving the ease of operation, reducing the difficulty and time cost of disassembly, meeting the needs of quick pick-up and drop-off in vehicle scenarios, and improving the user experience.

[0012] 2. By setting up reinforcement components, specifically the shape memory metal ring in the mounting groove of the suction cup is deformed by compression and then rebounds using the shape memory effect, continuously applying pre-tightening force to the edge of the suction cup, pushing the edge to tightly adhere to the adsorption surface, filling tiny gaps and curvatures, reducing air entry, strengthening the sealing effect, and improving the suction cup's adsorption force. This effectively resists the negative pressure leakage inside the suction cup and base caused by vehicle bumps and vibrations, which would reduce the suction cup's adsorption effect and cause it to fall off, thereby extending the bracket's service life and enhancing reliability in complex environments.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 As shown, this utility model is a quick-release device for a car phone holder, including a base 1, a suction cup 11 installed at the bottom of the base 1, a bracket 12 installed at the top of the base 1, and a communicating groove between the base 1 and the suction cup 11. It also includes: Disassembly mechanism 2 is installed inside the base 1. Disassembly mechanism 2 is used to break the negative pressure inside the suction cup 11, thereby quickly disassembling the entire device. The disassembly mechanism 2 eliminates the suction capacity of the suction cup 11 by balancing the air pressure inside and outside the suction cup 11, thereby quickly disassembling the base 1 and the bracket 12 from their installation position inside the vehicle.

[0019] The disassembly mechanism 2 includes a sealing assembly 21, which is installed on the outside of the base 1. The sealing assembly 21 is used to prevent air pressure leakage from the suction cup 11 and the inside of the base 1; and Ventilation component 22 is installed inside the base 1. Ventilation component 22 is used to disrupt the sealing effect of sealing component 21, thereby allowing the gas inside the base 1 and suction cup 11 to communicate with the external gas. Reset component 23 is installed inside the base 1. The reset component 23 is used to restore the sealing effect of the sealing component 21 after the venting component 22 damages the sealing effect of the sealing component 21. The reinforcing component 24 is installed inside the suction cup 11. The reinforcing component 24 is used to generate a pre-tightening force on the edge of the suction cup 11, so that the edge of the suction cup 11 fits more tightly to the surface being adsorbed. The sealing component 21, the ventilation component 22, and the reset component 23 are used to quickly eliminate the adsorption capacity of the suction cup 11 and quickly disassemble the bracket 12. The reinforcing component 24 is used to enhance the adsorption effect of the suction cup 11.

[0020] The sealing assembly 21 includes a vent pipe 211 fixedly connected to the outer wall of the base 1. The vent pipe 211 communicates with the interior of the base 1. A fixing block 212 is fixedly connected to the inner wall of the vent pipe 211. A vent groove 213 is opened on the inner wall of the fixing block 212. A sealing block 214 is slidably connected to the inner wall of the vent groove 213. Among them, the sealing block 214 is made of materials such as silicone and rubber with good elasticity and excellent sealing performance. It can fill the gap by utilizing the elasticity of the material itself and reduce the risk of movement without human intervention.

[0021] The ventilation assembly 22 includes a fixed plate 221 fixedly connected to the inner top wall of the base 1, a connecting rod 222 fixedly connected to the right end of the sealing block 214, the right end of the connecting rod 222 passing through the fixed plate 221 and extending to the outside of the base 1, the connecting rod 222 being slidably connected to the fixed plate 221 and the base 1 respectively, and a button 223 fixedly connected to the right end of the connecting rod 222. The button 223 is integrally molded and fixedly connected to the connecting rod 222.

[0022] The reset assembly 23 includes a connecting ring 231 fixedly connected to the outer wall of the connecting rod 222, and a spring 232 is sleeved on the outer wall of the connecting rod 222; One end of the spring 232 is fixedly connected to the connecting ring 231, and the other end is fixedly connected to the fixing plate 221.

[0023] The reinforcement component 24 includes a mounting groove 241 formed inside the suction cup 11, and a memory metal ring 242 is installed on the inner wall of the mounting groove 241. Among them, the memory metal ring 242 is made of nickel-titanium alloy material, which ensures sufficient strength to apply pre-tightening force to the edge of the suction cup 11, and will not affect the flexibility and adhesion of the suction cup 11 due to being too thick and hard.

[0024] One specific application of this embodiment is as follows: When using the device, when the suction cup 11 of the car phone holder is attached to the installation position, the user presses the bracket 12 on the top of the base 1, causing the air inside the suction cup 11 and the base 1 to be squeezed out. Since the sealing block 214 in the sealing assembly 21 is tightly fitted into the ventilation groove 213, it prevents external air from entering. As the pressure is applied, a negative pressure is formed inside the suction cup 11, creating a pressure difference with the outside. Under the action of the external atmospheric pressure, the suction cup 11 is firmly attached to the installation position. At the same time, the suction cup 11 is installed inside... The shape memory metal ring 242 inside the groove 241 is compressed and deformed to fit the mounting surface. After release, the shape memory metal ring 242 tends to rebound due to its shape memory effect, continuously applying pre-tightening force to the edge of the suction cup 11. This further compresses the edge of the suction cup 11, making it fit more tightly to the adsorption surface. Even if there are slight unevenness or curvature on the adsorption surface, the pre-tightening force of the shape memory metal ring 242 can push the edge of the suction cup 11 to fill the gaps and fit the curved surface, greatly reducing the possibility of air entering, enhancing the sealing effect, and thus improving the performance of the suction cup 11. The suction capacity ensures the stability and reliability of the bracket 12 during use. When the bracket needs to be disassembled, press button 223. Button 223 moves connecting rod 222 to the left, and connecting rod 222 pushes sealing block 214 to gradually separate from vent groove 213, creating a gap between them. External air enters the base 1 and suction cup 11 through vent pipe 211 and vent groove 213, balancing the internal and external air pressure, thus eliminating the suction capacity of suction cup 11. At this time, the base 1 and bracket 12 can be easily removed from the vehicle installation position. The bracket 12 is quickly removed from its installation position inside the vehicle. After the button 223 is released, the spring 232 in the reset assembly 23, which had stored elastic potential energy due to the compression of the connecting ring 231, releases the elastic potential energy and drives the connecting rod 222 to reset. The connecting rod 222 then drives the sealing block 214 to re-fit into the vent groove 213 to restore the sealing effect for the next adsorption. At the same time, the shape memory metal ring 242 returns to its original shape after losing external pressure, preparing to provide pre-tightening force to the edge of the suction cup 11 for the next adsorption.
