Description

Technical Field

[0001] This utility model relates to the field of mobile phone fixing accessories, and in particular to a mobile phone stand. Background Technology

[0002] When drivers use electric vehicles, motorcycles, or bicycles, they often need to use their mobile phones to check navigation and make communications. However, most vehicles are not equipped with mobile phone mounting devices, so a mobile phone holder needs to be installed to secure it.

[0003] Most existing phone holders generally use a single spring to install the clamping components. Due to the high frequency of use of phone holders, frequent stretching and recovery can cause fatigue in the spring material, gradually forming micro-cracks that expand and eventually may break. Common phone holders generally provide clamping force in two directions: left and right. There are also phone holders that provide additional bottom support, but these lack clamping support for the top of the phone.

[0004] Phone holders need to provide clamping force in four directions (up, down, left, and right), which often makes it difficult to place the phone. Moreover, most phone holders have limited functionality and cannot meet the needs of extended battery life while traveling. Therefore, it is necessary to design a phone holder that can provide clamping force in multiple directions without affecting the placement of the phone, and can also meet the needs of extended battery life while traveling. Utility Model Content

[0005] This utility model provides a mobile phone holder that can solve the problems of existing mobile phone holders that cannot provide multi-directional clamping force, are inconvenient to place the phone, and cannot meet the needs of travel battery life.

[0006] This application proposes a mobile phone holder, including a holder housing, which includes a first housing and a second housing. The first housing covers the second housing to form a cavity. The left and right sides of the first housing are respectively provided with a left clamping plate and a right clamping plate. The left clamping plate is provided with a quick-release post facing the first housing. A quick-release screw passes through the right clamping plate and is threadedly engaged with the quick-release post in the cavity. The upper and lower sides of the second housing are respectively provided with an upper clamping plate and a lower clamping plate. The upper and lower clamping plates are respectively provided with a first sliding part and a second sliding part facing the second housing. The first sliding part and the second sliding part are slidably disposed in the cavity in a vertical direction.

[0007] By adopting the above technical solution, the clamping plates in the four directions of the bracket box (upper, lower, left, and right) are arranged in an alternating manner in the cavity. This ensures that clamping force is provided in four directions while avoiding structural conflicts when the four clamping plates slide in the cavity. Furthermore, the clamping plates in the four directions can be flexibly adjusted as needed to better meet the usage requirements in different scenarios.

[0008] Preferably, the left and right clamps are provided with positioning parts on the upper and lower sides corresponding to the quick-release post and quick-release screw, the inner surface of the first box is provided with guide grooves at the positions corresponding to the positioning parts, and spring spacers are provided between the two guide grooves on the left and right sides. The inner surface of the first box is provided with arc-shaped recesses at the positions corresponding to the quick-release post and quick-release screw.

[0009] By adopting the above technical solution, the positioning part cooperates with the guide groove to guide the sliding direction of the left and right clamping plates, avoiding deflection during the feeding process of the quick-release screw and quick-release post. The spring baffle between the left and right opposite guide grooves can prevent the left and right clamping plates from sliding in the opposite direction. The arc-shaped concave surface of the inner surface of the first box is more suitable for the shape of the quick-release post and quick-release screw, which is conducive to improving the smoothness of the sliding of the left and right clamping plates.

[0010] Preferably, an anti-disengagement component is fitted onto the smooth part of the quick-release screw. The anti-disengagement component is inserted into a slot on the inner surface of the right side of the first housing. The end of the smooth part is hinged to the first wrench. The right surface of the right clamp is provided with a recess corresponding to the shape of the first wrench.

[0011] By adopting the above technical solution, the anti-detachment component helps to prevent the quick-release screw and quick-release post from completely disengaging, causing the right clamp to detach completely from the first housing. The first wrench helps to quickly and forcefully lock the left and right clamps.

[0012] Preferably, the inner sides of the upper and lower sides of the second box are provided with a first sliding seat and a second sliding seat along the sliding direction of the first sliding part and the second sliding part, respectively. The first sliding seat and the second sliding seat are respectively provided with through holes adapted to the size of the first sliding part and the second sliding part. The inner surface of the second box is provided with arc-shaped recesses at the positions corresponding to the first sliding part and the second sliding part.

[0013] By adopting the above technical solution, the first sliding seat and the second sliding seat can better guide the sliding direction of the first sliding part and the second sliding part, and play a role in strengthening the support. At the same time, the arc-shaped recess on the second box can also ensure the smoothness of the upper clamping plate and the lower clamping plate when sliding.

[0014] More preferably, the ends of the first sliding part and the second sliding part are provided with annular grooves, which engage with the limiting spring in the cavity. The size of the limiting spring is larger than the through hole size of the first sliding seat and the second sliding seat.

[0015] By adopting the above technical solution, the annular groove cooperates with the limiting spring. When the ends of the first sliding part and the second sliding part are about to disengage from the first sliding seat and the second sliding seat, the limiting spring can abut against the first sliding seat / second sliding seat, preventing the upper clamping plate and the lower clamping plate from disengaging from the second box.

[0016] In a further preferred embodiment, a spring is fitted onto the first sliding part, the length of the spring covering the sliding stroke of the first sliding part, and the two ends of the spring abut against the limiting snap ring and the first sliding seat, respectively.

[0017] By adopting the above technical solution, the spring is configured to add an elastic reset function to the sliding of the upper clamping plate. When the upper clamping plate slides upward, it compresses the spring. After the mobile phone or electronic device is placed on the mobile phone holder, the upper clamping plate quickly clamps the mobile phone or electronic device downward under the action of the spring releasing the compression and reset force.

[0018] Preferably, the cavity is further provided with a pressure block for pressing the second sliding part. The surface of the pressure block facing the second sliding part is provided with an arc-shaped recess, and the connecting part at the center of the pressure block vertically passes through the back of the second box and is hinged to the second wrench. The inner surface of the second box and the pressure block are respectively provided with a positioning groove and a positioning boss that cooperate with each other.

[0019] By adopting the above technical solution, the positioning groove and positioning boss enable the pressure block to be accurately positioned on the surface of the second sliding part. Tightening the second wrench can drive the pressure block to press the second sliding part through the connecting part, preventing the lower clamping plate from falling downward.

[0020] Preferably, a PCB board is provided inside the cavity between the quick-release screw and the first sliding part, and a coil groove is provided on the outer surface of the first box. A charging coil is embedded in the coil groove, and a protective cover is also provided on the outside of the charging coil. The PCB board is electrically connected to the charging coil.

[0021] By adopting the above technical solution, when the front of the mobile phone holder is facing up, the PCB board can be installed above the first sliding part by opening the first box, which facilitates later maintenance and replacement. At the same time, the charging coil provides wireless charging for electronic devices during cycling.

[0022] In a further preferred embodiment, a buffer bracket is fixed to the back of the second box by bolts, and an elastic silicone gasket is provided between the buffer bracket and the second box.

[0023] By adopting the above technical solution, the bracket box is further fixed to the handle of the vehicle using a buffer bracket, and an elastic silicone gasket is set to provide shock absorption for the phone holder, so as to avoid the impact of vibration caused by vehicle bumps and high-frequency vibration generated by the vehicle engine on the stability of the phone holder, and at the same time reduce damage to the phone camera.

[0024] In a further preferred embodiment, the back of the second housing is also provided with a power output interface and a power button, which are electrically connected to the PCB board respectively, and the back of the second housing is also provided with a wire hole for external wires to pass through.

[0025] By adopting the above technical solution, the power output interface can be connected to an external power cord to charge electronic devices via wired connection. This is suitable for devices that do not have wireless charging capabilities. The power button allows users to easily activate the charging function as needed, avoiding energy waste. The PCB board is powered by an external power cord, ensuring that the phone holder's charging function receives stable power support.

[0026] Compared with the prior art, the beneficial effects of this application are as follows:

[0027] This phone holder features an innovative design that enhances user experience. It employs four-way clamps (top, bottom, left, and right) to strengthen device stability and grip. Quick-release posts and screws facilitate easy assembly and disassembly, preventing wear and structural conflicts. Elastic silicone pads on the clamps further protect the electronic device's appearance. The holder integrates a PCB board and charging coil for wireless charging, suitable for specific scenarios such as cycling. Anti-detachment components and limiting springs prevent accidental dislodgement of critical parts, improving safety. A buffer bracket and elastic silicone gaskets reduce vibrations from vehicle bumps, ensuring device stability in rough environments. A power output interface and power button provide convenient wired charging, a protective cover prevents interface damage, and an external power cord ensures stable charging. Overall, this phone holder, through a series of optimized designs, offers a more stable, safe, and convenient user experience, meeting diverse user needs in various scenarios.

It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] This application proposes a mobile phone holder. Figure 1 An exploded view of a mobile phone holder structure according to an embodiment of this application is shown. As shown, the mobile phone holder includes a holder housing, which includes a first housing 01 and a second housing 02. The first housing 01 covers the second housing 02 to form a cavity. A left clamping plate 03 and a right clamping plate 04 are respectively provided on the left and right sides of the first housing 01. A quick-release post 05 is provided on the left clamping plate 03 facing the first housing 01. A quick-release screw 06 passes through the right clamping plate 04 and is threadedly engaged with the quick-release post 05 in the cavity. An upper clamping plate 07 and a lower clamping plate 08 are respectively provided on the upper and lower sides of the second housing 02. A first sliding part 09 and a second sliding part 10 are respectively provided on the upper clamping plate 07 and the lower clamping plate 08 facing the second housing 02. The first sliding part 09 and the second sliding part 10 are respectively slidably disposed in the cavity in the vertical direction.

[0039] Specifically, the left clamping plate 03, right clamping plate 04, upper clamping plate 07, and lower clamping plate 08 are all provided with elastic silicone protective pads (not shown in the figure) facing the clamping direction, which can prevent wear on the surface of the electronic device due to rigid contact when the clamping plates are clamped together.

[0040] Specifically, the first box 01 and the second box 02 are fitted together by multiple positioning pins and positioning bosses. After the first box 01 is placed on the second box 02, several bolts pass through the back of the second box 02 and are threaded to the first box 01.

[0041] By adopting the above technical solution, the clamping plates in the four directions of the bracket box (upper, lower, left, and right) are arranged in an alternating manner in the cavity. This ensures that clamping force is provided in four directions while avoiding structural conflicts when the four clamping plates slide in the cavity. Furthermore, the clamping plates in the four directions can be flexibly adjusted as needed to better meet the usage requirements in different scenarios.

[0042] Figure 2 A schematic diagram of the left and right clamping plates installation according to an embodiment of this application is shown, as follows: Figure 1-2 As shown, the left clamping plate 03 and the right clamping plate 04 are provided with positioning parts 11 on the upper and lower sides corresponding to the quick-release post 05 and the quick-release screw 06. The inner surface of the first box 01 is provided with guide grooves 12 corresponding to the positioning parts 11, and a spring partition (not shown in the figure) is provided between the two opposite guide grooves 12. The spring partition consists of a buffer spring (not shown in the figure) sleeved on the end of the positioning part 11 and a partition (not shown in the figure) provided between the opposite guide grooves 12. That is, the guide grooves 12 on the left and right sides of the first box 01 are not connected. When the positioning part 11 is about to contact the partition, the buffer spring is compressed and provides buffering force. The inner surface of the first box 01 is provided with arc-shaped recesses corresponding to the quick-release post 05 and the quick-release screw 06.

[0043] By adopting the above technical solution, the positioning part 11 cooperates with the guide groove 12 to guide the sliding direction of the left clamping plate 03 and the right clamping plate 04, so as to avoid deflection during the feeding process of the quick release screw 06 and the quick release column 05. The spring spacer between the left and right opposite guide grooves 12 can prevent the left clamping plate 03 and the right clamping plate 04 from sliding in the opposite direction. The arc-shaped concave on the inner surface of the first box 01 is more suitable for the shape of the quick release column 05 and the quick release screw 06, which is conducive to improving the smoothness of the sliding of the left clamping plate 03 and the right clamping plate 04.

[0044] Preferably, an anti-detachment component 14 is fitted on the bare rod portion 13 of the quick-release screw 06. The anti-detachment component 14 is inserted into the slot 15 on the inner surface of the right side of the first housing 01. The end of the bare rod portion 13 is hinged to the first wrench 16. The right surface of the right clamping plate 04 is provided with a recess corresponding to the shape of the first wrench 16.

[0045] Specifically, the diameter of the hole at the center of the anti-detachment part 14 is smaller than the thread diameter of the quick-release screw 06. During installation, the anti-detachment part 14 passes through the end of the smooth rod 13, which can prevent the anti-detachment part 14 from coming off when the threaded part of the quick-release rod moves to the right.

[0046] Furthermore, by tightening the first wrench 16, the quick-release screw 06 can be pulled to the right, thereby preventing the left clamp 03 and the right clamp 04 from moving. After opening the first wrench 16, rotating the quick-release screw 06 will cause the left clamp 03 and the right clamp 04 to simultaneously loosen outward or clamp inward on the electronic equipment.

[0047] By adopting the above technical solution, the anti-detachment component 14 helps to prevent the quick-release screw 06 from completely disengaging from the quick-release post 05, causing the right clamping plate 04 to detach completely from the first box 01. The first wrench 16 helps to quickly and forcefully lock the left clamping plate 03 and the right clamping plate 04.

[0048] Figure 3 A schematic diagram of the installation of the upper and lower clamping plates according to an embodiment of this application is shown, as follows: Figure 1-3 As shown, preferably, the inner sides of the upper and lower sides of the second box 02 are provided with a first sliding seat 17 and a second sliding seat 18 along the sliding direction of the first sliding part 09 and the second sliding part 10, respectively. The first sliding seat 17 and the second sliding seat 18 are respectively provided with through holes adapted to the size of the first sliding part 09 and the second sliding part 10. The inner surface of the second box 02 is provided with arc-shaped recesses at the positions corresponding to the first sliding part 09 and the second sliding part 10.

[0049] Specifically, both the first sliding part 09 and the second sliding part 10 consist of two symmetrical sliding rods; the lower clamp 08 can be a double-claw structure with a gap between the two claws, so that when the electronic device needs to be charged, the power cord can be connected to the charging port of the electronic device from below.

[0050] By adopting the above technical solution, the first sliding seat 17 and the second sliding seat 18 can better guide the sliding direction of the first sliding part 09 and the second sliding part 10, and play a role in strengthening support. At the same time, the arc-shaped recess on the second box 02 can also ensure the smoothness of the upper clamping plate 07 and the lower clamping plate 08 when sliding.

[0051] More preferably, the ends of the first sliding part 09 and the second sliding part 10 are provided with annular grooves 19, which engage with the limiting spring 20 in the cavity. The size of the limiting spring 20 is larger than the through hole size of the first sliding seat 17 and the second sliding seat 18.

[0052] By adopting the above technical solution, the annular groove 19 cooperates with the limiting spring 20. When the ends of the first sliding part 09 and the second sliding part 10 are about to disengage from the first sliding seat 17 and the second sliding seat 18, the limiting spring 20 can abut against the first sliding seat 17 / second sliding seat 18 to prevent the upper clamping plate 07 and the lower clamping plate 08 from disengaging from the second box 02.

[0053] More preferably, a spring 21 is sleeved on the first sliding part 09, the length of the spring 21 covers the sliding stroke of the first sliding part 09, and the two ends of the spring 21 abut against the limiting snap ring 20 and the first sliding seat 17 respectively.

[0054] By adopting the above technical solution, the spring 21 is configured to have an elastic reset function when the upper clamping plate 07 slides upward. When the upper clamping plate 07 slides upward, it compresses the spring 21. After the mobile phone or electronic device is placed on the mobile phone holder, the upper clamping plate 07 quickly clamps the mobile phone or electronic device downward under the action of the spring 21 releasing the compression and reset force.

[0055] Preferably, the cavity is further provided with a pressing block 22 for pressing the second sliding part 10. The surface of the pressing block 22 facing the second sliding part 10 is provided with an arc-shaped recess, and the connecting part 23 at the center of the pressing block 22 vertically passes through the back of the second box 02 and is hinged to the second wrench 24. The inner surface of the second box 02 and the pressing block 22 are respectively provided with a positioning groove 25 and a positioning boss (not shown in the figure).

[0056] By adopting the above technical solution, the positioning groove 25 and the positioning boss are set so that the pressure block 22 is accurately positioned on the surface of the second sliding part 10. By tightening the second wrench 24, the pressure block 22 can be driven to press the second sliding part 10 through the connecting part 23, preventing the lower clamping plate 08 from falling downward.

[0057] Figure 4 Another exploded view of the structure of a mobile phone holder according to an embodiment of this application is shown, as follows. Figure 1-4 As shown, preferably, a PCB board 26 is provided inside the cavity between the quick-release screw 06 and the first sliding part 09, a coil groove 27 is provided on the outer surface of the first box 01, a charging coil 28 is embedded in the coil groove 27, and a protective cover 29 is also provided on the outside of the charging coil 28. The PCB board 26 is electrically connected to the charging coil 28.

[0058] Furthermore, the PCB board 26 is positioned inside the second box 02 by multiple positioning posts. Meanwhile, in order to better display the charging status, an indicator light 30 is also provided on the side of the first box 01.

[0059] By adopting the above technical solution, when the front of the mobile phone holder is facing up, the PCB board 26 can be installed on top of the first sliding part 09 by opening the first box 01, which is convenient for later maintenance and replacement. At the same time, the charging coil 28 is used to provide wireless charging for electronic devices during riding.

[0060] Figure 5 A schematic diagram of the back structure of the second housing according to an embodiment of this application is shown, as follows. Figure 1-5 As shown, in a further preferred embodiment, a buffer bracket 31 is fixed to the back of the second box 02 by bolts, and an elastic silicone gasket 32 ​​is provided between the buffer bracket 31 and the second box 02.

[0061] Specifically, the buffer bracket 31 includes a fixed ball joint 33 for use with the universal mounting accessories of the mobile phone holder.

[0062] By adopting the above technical solution, the bracket box is further fixed to the position of the vehicle's handle by using the buffer bracket 31, and the elastic silicone gasket 32 ​​is set to provide shock absorption function for the mobile phone holder, so as to avoid the vibration caused by vehicle bumps and the high-frequency vibration generated by the vehicle engine from affecting the stability of the mobile phone holder, and at the same time reduce damage to the mobile phone camera.

[0063] In a further preferred embodiment, the back of the second housing 02 is also provided with a power output interface 34 and a power button 35. The power output interface 34 and the power button 35 are electrically connected to the PCB board 26 respectively. The back of the second housing 02 is also provided with a wire hole 36 for external wires to pass through. The wire hole 36 is surrounded by protrusions for enhancing support.

[0064] Specifically, when the power output interface 34 is not in use, an interface protective cover can be used to protect the power output interface 34.

[0065] By adopting the above technical solution, the power output interface 34 can be connected to an external power cord to charge electronic devices via wired connection, which is suitable for devices that do not have wireless charging capability. The power button 35 allows users to turn on the charging function as needed, avoiding energy waste. The PCB board 26 uses an external power cord to ensure that the charging function of the mobile phone holder receives stable power support.

[0066] This mobile phone holder features an innovative design that enhances user experience. It employs four-way clamps (top, bottom, left, and right) to strengthen device stability and grip. The quick-release posts 05 and quick-release screws 06 facilitate easy disassembly and adjustment, preventing wear and structural conflicts. Elastic silicone protective pads on the clamps further protect the electronic device's appearance. The holder integrates a PCB board 26 and a charging coil 28 for wireless charging, suitable for specific scenarios such as cycling. Anti-detachment components 14 and limit springs 20 prevent accidental dislodgement of critical components, improving safety. A buffer bracket 31 and elastic silicone gaskets 32 reduce vibration during cycling, ensuring device stability in bumpy environments. A power output interface 34 and a power button 35 provide convenient wired charging, with a protective cover preventing interface damage and an external power cord ensuring stable charging. Overall, this mobile phone holder, through a series of optimized designs, provides a more stable, safe, and convenient user experience, meeting diverse user needs in different scenarios.
