This invention discloses a mobile phone mounting bracket, comprising a back cover, a cover plate, a control button assembly, a drive mechanism assembly, a first clamping arm, and a second clamping arm. The back cover and the cover plate are closed together. The control button assembly controls the drive mechanism to move. The drive mechanism assembly drives the first clamping arm and the second clamping arm to move towards or away from each other, thereby clamping or releasing the mobile phone. The drive mechanism assembly includes a driving gear, a driven gear, and an elastic element. The outer surface of the driving gear has outer teeth that connect to the control button assembly, and the inner surface of the driving gear has inner teeth that drive the driven gear to rotate. The number of teeth on the inner teeth is greater than the number of teeth on the driven gear. One end of the elastic element is fixed to the back cover, and the other end is fixed to the driving gear. The rotation of the driving gear forces the elastic element to undergo elastic deformation, which can accurately position the opening stroke of the clamping arm and facilitate control.

Description

Technical Field

[0001] This invention relates to a mobile phone holder, and more particularly to a mobile phone fixing bracket. Background Technology

[0002] When used in a car, a phone holder needs to be both securely holding the phone and easy to operate by hand. Since phones of various sizes are available on the market, a holder with two adjustable clamping arms can accommodate different phone sizes for navigation. (Authorization Announcement No.: CN210807381) A Chinese patent, U, entitled "A Mobile Phone Fixing Stand," discloses a stand that fixes a mobile phone using two clamping arms and a supporting arm. The clamping arms are opened and closed by a switch button to hold mobile phones of different sizes. However, the following problems exist: 1. The driving and driven gears mesh with each other. When one clamping arm is fixed, the positions of the driving and driven gears are determined, and the other clamping arm can only be inserted into the teeth of the gear in the determined position. Because the teeth have thickness, a gap will remain between the clamping arm and the housing when the last clamping arm is fully retracted. 2. When the clamping arm is released by the switch button, the spring acts directly on the clamping arm, causing the spring to spring open instantly, releasing all energy, and the two clamping arms quickly and completely pop out, causing the phone to fall immediately. The distance between the clamping arms cannot be adjusted slowly, making it inconvenient to use. 3. The installation and removal process is complex. The driving and driven gears must be placed inside the housing first, then the first clamping arm must be placed, and then the second clamping arm must be placed, adjusting the distance between the two clamping arms. The installation process is complicated and production efficiency is low. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a mobile phone mounting bracket that can be modularly produced, thereby solving the aforementioned problems in the prior art.

[0004] The objective of this invention is achieved through the following technical solution: a mobile phone fixing bracket, comprising a back cover, a cover plate, a control button assembly, a drive mechanism assembly, a first clamping arm, and a second clamping arm, wherein the back cover and the cover plate are closed, the control button assembly controls the drive mechanism to operate, and the drive mechanism assembly drives the first clamping arm and the second clamping arm to move towards or away from each other to clamp or release the mobile phone, characterized in that: the drive mechanism assembly comprises a driving gear, a driven gear, and an elastic element, wherein the inner surface of the driving gear is provided with inner gear teeth that drive the driven gear to rotate, and the number of teeth of the inner gear teeth is greater than the number of teeth of the driven gear; one end of the elastic element is fixed to the back cover, and the other end is fixed to the driving gear, and the rotation of the driving gear can force the elastic element to undergo elastic deformation.

[0005] Preferably, the elastic element is a tension spring, and the drive gear has a raised circular platform on its side facing the back shell, with the tension spring wrapped around the circumference of the circular platform.

[0006] Preferably, the elastic element is a spring, and the driving gear has a spring-receiving cavity in the middle.

[0007] Preferably, the drive gear is mounted on a fixed plate, and the fixed plate has a fence around the drive gear in the middle, and the fixed plate is fixed inside the back shell.

[0008] Preferably, the driven gear has a driven upper gear protruding from the end face of the driven gear in the middle, and the upper and lower teeth of the driven upper gear are respectively engaged with the first and second clamping arms.

[0009] As a further improvement to the above solution, a Π-shaped frame is provided on the inner side of the first clamping arm and the inner side of the second clamping arm, and both Π-shaped frames are provided with clearance grooves to accommodate each other.

[0010] Preferably, an intermediate gear is provided between the driving gear and the driven gear, and the intermediate gear is connected to both the inner gear teeth and the driven gear teeth.

[0011] Preferably, the control button assembly includes a transmission gear, a latch connected to the transmission gear, and a button linkage plate. The button linkage plate is provided with transverse linear gear teeth corresponding to the transmission gear, and the lower end of the latch engages with the outer gear teeth.

[0012] Preferably, the button linkage plate includes a first button linkage plate and a second button linkage plate arranged side by side and intersecting each other. The middle part of the first button linkage plate and the middle part of the second button linkage plate are provided with through holes for accommodating transmission gears. The lower edge of the through hole of the first button linkage plate and the upper edge of the through hole of the second button linkage plate are respectively provided with transverse linear gear teeth corresponding to the transmission gears.

[0013] As a further improvement to the above solution, the outer surface of the drive gear is provided with outer gear teeth that are connected to the control button assembly. The latch is tilted downward, the transmission gear is fixed at the upper end of the latch, and a spring is provided above the other end of the latch. The outer gear teeth and the latch form a ratchet mechanism. The latch is vertically downward, and one side of the latch is provided with vertical straight gear teeth that mesh with the transmission gear. A spring is provided in the middle of the latch.

[0014] The present invention has the following advantages and effects compared with the prior art:

[0015] Precise control: The energy storage and release of the elastic element must be carried out through the driving gear. The opening stroke of the first and second clamping arms can be precisely controlled by the speed ratio between the driving gear and the driven gear.

[0016] More aesthetically pleasing: The first and second clamping arms are driven by the same driven gear, and the two clamping arms are on the same plane, preventing a gap from remaining between one of the clamping arms and the back shell after the clamping arms are fully retracted.

[0017] Space saving: The driving gear and driven gear are on the same center, and they are driven by an intermediate gear, making the layout more space-saving.

[0018] High production efficiency: The drive mechanism can pre-assemble finished products. The production of mobile phone holders only requires fixing the pre-formed drive mechanism, which greatly increases production efficiency.

[0019] To prevent malfunction: The transmission gear drives the movement of the clasp, ensuring the accuracy of the clasp's action. The transmission gear has a large stroke, ensuring that the clasp can definitely disengage from the outer gear teeth.

[0020] The ratchet mechanism prevents the phone from becoming loose. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0029] Example 1

[0030] Reference Figures 1-6A mobile phone mounting bracket includes a back cover 1, a cover plate 2, a control button assembly 5, a drive mechanism assembly 6, a first clamping arm 3, and a second clamping arm 4. The back cover 1 and the cover plate 2 are closed together, fixing the control button assembly 5 and the drive mechanism assembly 6 inside. The first clamping arm 3 and the second clamping arm 4 slide between the back cover 1 and the cover plate 2. The control button assembly controls the drive mechanism. The drive mechanism can be activated or stopped by manually operating the control button assembly. The drive mechanism assembly drives the first clamping arm 3 and the second clamping arm 4 to move towards or away from each other, thereby clamping or releasing the mobile phone. The drive mechanism assembly includes a driving gear 61, a driven gear 62, and an elastic element 63. The outer surface of the driving gear 61 is provided with outer teeth 64 that connect to the control button assembly, and the inner surface of the driving gear 61 is provided with inner teeth 65 that drive the driven gear 62 to rotate. The number of teeth of the inner teeth 65 is greater than the number of teeth of the driven gear 62. One end of the elastic element 63 is fixed to the back cover 1, and the other end is fixed to the driving gear 61. The rotation of the driving gear 61 can force the elastic element 63 to undergo elastic deformation. In use, by opening the first clamping arm 3 and the second clamping arm 4, the driven gear 62 is driven, and the driving gear 61 drives the elastic element 63 to deform and store energy. The control button assembly prevents the first clamping arm 3 and the second clamping arm 4 from opening in the opposite direction (fixing the mobile phone).

[0031] In a preferred embodiment, the elastic element 63 is a tension spring. The driving gear 61 has a raised circular platform 66 on its side facing the back shell. The tension spring is wrapped around the circumference of the circular platform 66. When the first clamping arm 3 and the second clamping arm 4 approach and retract, the driven gear 62 drives the driving gear 61. During the movement, the driving gear 61 stretches the tension spring and stores energy. When the control button assembly is activated, the tension spring drives the driving gear 61 to rotate in the opposite direction and opens the first clamping arm 3 and the second clamping arm 4 through the driven gear 62. Since the number of teeth of the inner gear 65 is greater than the number of teeth of the driven gear 62, a certain speed ratio is formed between the two. During the process of the first clamping arm 3 and the second clamping arm 4 driving the tension spring, a small displacement of the clamping arm can cause the tension spring to deform into a large deformation and store energy. Since the energy release of the tension spring must first be achieved through the rotation of the driving gear 61, the rotation of the gear is relatively easy to control. After the driving gear 61 drives the driven gear 62 to increase the speed, the opening stroke of the two clamping arms can be controlled at will by jogging the control button assembly.

[0032] To facilitate the production of drive mechanism components on the assembly line, the drive mechanism components are assembled first before the complete mobile phone holder is produced, which significantly improves production efficiency. Therefore, the drive gear 61 is mounted on the fixed plate 67, and the fixed plate 67 has a fence 68 for the drive gear 61 in the middle. The fixed plate 67 is fixed to the back shell 1 with screws. Installing and removing the fixed plate 67 can realize the overall installation and disassembly of the drive mechanism components, thereby improving work efficiency.

[0033] The preferred method is that the driven gear 62 has a driven upper gear 621 protruding from the end face of the driven gear 62 in the middle. The upper and lower teeth of the driven upper gear 621 are respectively engaged with the teeth of the first and second clamping arms. The driven gear 62 drives the opening of the first and second clamping arms through the driven upper gear 621. Conversely, the first and second clamping arms drive the rotation of the driven gear 62 and the driving gear 61 through the driven upper gear 621.

[0034] A further improvement to the above solution is that a Π-shaped frame 7 is provided on the inner side of the first clamping arm 3 and the inner side of the second clamping arm 4. Both Π-shaped frames 7 are provided with clearance grooves 8 to accommodate each other. In the two Π-shaped frames 7, one side of one Π-shaped frame 7 is embedded in the clearance groove 8 of the other, and the other side is close to the upper edge of the other Π-shaped frame 7, forming two Π-shaped frames 7 that are intersected and side by side and can move relative to each other. The effect achieved is that the movement of the two clamping arms can be driven simultaneously by a driven upper gear 621. The front of the housing 1 is provided with transverse guide grooves 10 for the first clamping arm 3 and the second clamping arm 4 to prevent the first clamping arm 3 or the second clamping arm 4 from deviating. The housing 1 is also provided with a latch 11 for the cover plate 2.

[0035] In the above scheme, an intermediate gear 69 is provided between the driving gear 61 and the driven gear 62. The intermediate gear 69 is connected to the inner gear teeth 65 and the teeth of the driven gear 62. The intermediate gear 69 serves to connect the driving gear 61 and the driven gear 62. At the same time, the circles of the driving gear 61 and the driven gear 62 are used as concentric circles, which facilitates the layout of the driven gear 62 and saves space.

[0036] Preferably, the control button assembly 5 includes a transmission gear 51, a latch 52 connected to the transmission gear 51, and a first button linkage plate 53 and a second button linkage plate 54 arranged side by side. The middle of the first button linkage plate 53 and the middle of the second button linkage plate 54 are each provided with a through hole 55 to accommodate the transmission gear 51. The lower edge of the through hole in the first button linkage plate 53 and the upper edge of the through hole in the second button linkage plate 54 are respectively provided with transverse linear gear teeth 56 corresponding to the transmission gear 51. The lower end of the latch 52 engages with the outer gear teeth 64. The first button linkage plate 53 and the second button linkage plate 54 extend out of the back shell 1 to form two buttons, left and right. Therefore, the control button assembly of the present invention has the following effects: 1. The opening stroke of the two clamping arms can be controlled by a single left button, a single right button, or both left and right buttons, which is very user-friendly and convenient to operate (existing technology can only be operated by a single switch button); 2. The transmission gear 51 drives the latch 52 to move, ensuring the accuracy of the latch 52's movement. (In the prior art, the card plate is pushed by the switch button and the switch button tilting platform. Due to the gap between the tilting platform and the card plate, the card plate sometimes does not respond, and the switch button malfunctions); 3. The transmission gear 51 can drive the latch 52 to a large stroke, ensuring that the latch 52 can definitely disengage from the outer gear tooth 64. (In the prior art, through the contact of the two tilting platforms, the front half of the tilting platform must be engaged first, so the rear half of the tilting platform only works, and its pushing stroke of the card plate is limited, which may cause the card plate to malfunction). The housing 1 is provided with a limiting block 57 for the first button linkage plate 53 and the second button linkage plate 54.

[0037] To prevent the phone from wobbling when the vehicle shakes, causing the latch 52 to disengage from the outer gear tooth 64 and thus loosening the phone, the outer gear tooth 64 and the latch 52 form a ratchet mechanism to prevent the two clamping arms from automatically releasing.

[0038] In this embodiment, the latch 52 is tilted downward, the transmission gear 62 is fixed at the upper end of the latch 52, and a spring is provided above the other end of the latch 52, which can restore the latch 52 to its initial position.

[0039] A support arm 9 is provided below the cover plate 2.

[0040] Example 2

[0041] As an alternative, the elastic element 63 is a spring, and the driving gear 61 has a spring-receiving cavity in the middle. Since one end of the spring is fixed to the housing 1, the spring deforms when the driving gear 61 rotates, thereby achieving the effect of energy storage.

[0042] Reference Figure 7The latch 52 is vertically downward. One side of the latch 52 is provided with vertical linear teeth that mesh with the transmission gear 62. A spring 58 is provided in the middle of the latch 52. The transmission gear 62 drives the latch 52 to move through the vertical linear teeth, causing the latch 52 to disengage from the outer teeth 64. The spring 58 causes the latch 52 to return to its initial position.

[0043] In this embodiment, except for the structure of the elastic element 63 and the structure of the latch 52, the other structures are the same as in Embodiment 1.

[0044] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
