[0002] With the rapid development of smart phones, touch-screen mobile phones have a very high penetration rate, and their functional applications are extremely diverse. People can be seen using mobile phones for operations everywhere. However, when cycling, the navigation function and some communication needs of smart phones are also used. Considering the problem of cycling safety, the placement of mobile phones has become an important factor affecting safety. Traditional mobile phone brackets all require manual adjustment of the tightness of the mobile phone bracket for clamping the mobile phone. Of course, there are also mobile phone brackets with automatic clamping design now, which generally detect whether a mobile phone is placed through a pressure sensor.

[0003] In the related art, for the manually adjustable mobile phone bracket, it is generally locked by screw-type pressing in the current market, that is, the tightness of the mobile phone bracket is adjusted by rotating the screw. However, when you want to change the mobile phone, you need to rotate the screw to loosen the mobile phone bracket, and after putting in the mobile phone, you need to rotate the screw in the reverse direction to tighten the mobile phone bracket, which makes it take a long time to rotate the screw when changing the mobile phone, resulting in inconvenience and lack of convenience for users.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. When it is necessary to adjust the size of the space for placing the mobile phone on the mobile phone holder, turn the handle to a predetermined angle. At this time, the handle will drive the eccentric wheel to rotate around the base center through the shaft. Under the action of the top center of the eccentric wheel, the side of the sliding rod close to the eccentric wheel will swing. Then the limiting rod located in the limiting groove of the sliding rod will be at the sliding hole of the sliding rod under the action of the swing of the sliding rod. Therefore, the user can directly pull the right bracket to adjust the distance between the two installation positions. After the adjustment is completed, turn the handle back to its original position. The eccentric wheel will drive the sliding rod to swing back to its original position. At this time, the limiting rod will be in the limiting groove of the sliding rod. The limiting rod can be restricted through the limiting groove to fix the distance between the installation positions on the left bracket and the right bracket, preventing the mobile phone from falling. Compared with the method realized by the screw, in this design method, only by turning the handle, the distance between the installation positions on the left bracket and the right bracket can be released. After the distance adjustment is completed, turning the handle back to its original position can again fix the distance between the installation positions on the left bracket and the right bracket. Thus, the operation of adjusting the size of the space for placing the mobile phone on the mobile phone holder can be made simpler, which helps to improve the user experience during use;

[0019] 2. Due to the settings of the limiting ring and the first knob, when it is necessary to adjust the space for mounting the mobile phone on the mobile phone holder, rotate the first knob so that the first knob moves towards the side away from the limiting ring under the screw connection between the limiting rod and the limiting ring. At this time, the two side surfaces of the sliding rod will be separated from the limiting ring and the second knob respectively. At this time, the handle can be rotated to swing the sliding rod. After the adjustment is completed, rotate the first knob in the reverse direction so that the mutually approaching side surfaces of the first knob and the limiting ring are respectively abutted against the opposite side surfaces of the sliding rod. Under the action of friction, the sliding rod is kept stationary, which can improve the installation stability between the left bracket and the right bracket, and try to avoid the phenomenon that the mobile phone falls and is damaged due to insufficient clamping force. At the same time, through the settings of the first card slot, the second card slot and the card block, when the first knob is tightened, multiple card blocks will be respectively stuck into the corresponding first card slot and the second card slot, further avoiding the phenomenon that the sliding rod slides and causes the distance between the mounting positions on the left bracket and the right bracket to change;

[0020] 3. Due to the settings of the mounting cylinder, the mounting block, the insertion rod, the telescopic pin, the telescopic spring, the clamping plate, the second knob and the fixing pin, when it is necessary to adjust the space for mounting the mobile phone on the mobile phone holder, first pull up the second knob. Under the action of the fixing pin, the telescopic pin will be pulled up synchronously with the second knob. At this time, the insertion rod will be pulled out of the limiting groove, and at the same time, the clamping plate will also move out of the avoidance groove of the second knob. Then rotate the second knob so that the avoidance groove and the clamping plate are staggered. At this time, release the second knob, and the lower side surface of the second knob will abut against the clamping plate. At this time, the insertion rod will have a predetermined distance from the limiting groove, which will not affect the sliding of the right bracket relative to the left bracket. After the adjustment is completed, rotate the second knob so that the avoidance groove on the second knob corresponds to the clamping plate. At this time, under the action of the telescopic spring, the insertion rod is inserted into the limiting groove, thereby further improving the connection stability between the left bracket and the right bracket.

Detailed implementation manners

[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.

[0031] The embodiment of the present application discloses a mobile phone bracket with a quick unlocking function. Refer to Figures 1 to 7, a mobile phone holder with a quick unlocking function includes a left holder 1 and a right holder 2. The right holder 2 is connected to the left holder 1, and the right holder 2 can slide relative to the left holder 1. Mounting positions 3 are provided on both the left holder 1 and the right holder 2. The two mounting positions 3 are arranged opposite to each other to form a U-shaped area for placing the mobile phone. An installation cavity 11 for the right holder 2 to slide is provided on the side of the left holder 1, and a protruding portion 21 that slides in the installation cavity 11 is provided on the side of the right holder 2. A clamping spring 12 is provided in the installation cavity 11. The clamping spring 12 is connected to the inner wall of the installation cavity 11 and the protruding portion 21, so that the left holder 1 and the right holder 2 form an elastic connection for easy adjustment. A quick unlocking device 4 is provided on the left holder 1 and the right holder 2. When it is necessary to adjust the distance between the two mounting positions 3, the position limitation between the left holder 1 and the right holder 2 is released through the quick unlocking device 4 on the left holder 1 and the right holder 2. After the adjustment is completed, the left holder 1 and the right holder 2 are limited again through the quick unlocking device 4, which helps to improve the user experience during use.

[0032] Refer to Figures 2 to 7, the quick unlocking device 4 includes a handle 41, an eccentric wheel 42, a sliding rod 43 and a limiting rod 44. Specifically, the handle 41 is arranged on the side of the right bracket 2, and the handle 41 can rotate on the handle 41. In this embodiment, the rotation range of the handle 41 is 0-180°. The eccentric wheel 42 is connected to the right bracket 2 and arranged below the handle 41. The base center of the eccentric wheel 42 and the handle 41 are synchronously rotated through a shaft. The sliding rod 43 is in a long strip shape. One end of the sliding rod 43 is rotatably connected to the top center of the eccentric wheel 42 to form a structure similar to a crank-slider mechanism. The sliding rod 43 is entirely below the left bracket 1 and the right bracket 2. A sliding hole 431 is arranged along the length direction of the sliding rod 43. The sliding hole 431 is in a waist shape. A limiting groove 432 is arranged on the inner wall of the sliding hole 431 along the length direction. The limiting groove 432 is in the form of an up-and-down through groove, and the cross-section of the limiting groove 432 is semicircular when viewed from the opening direction. A plurality of limiting grooves 432 are arranged, and the plurality of limiting grooves 432 are equally spaced. The limiting rod 44 is in a cylindrical rod shape. The limiting rod 44 passes through the sliding groove, and the limiting rod 44 is adapted to the shape of the limiting groove 432. The limiting rod 44 is used to be inserted into the limiting groove 432. Therefore, when it is necessary to adjust the size of the space for placing the mobile phone on the mobile phone holder, first rotate the handle 41 along a predetermined direction. In this embodiment, it is rotated 180°. At this time, the eccentric wheel 42 will be synchronously rotated under the action of the handle 41, so that the sliding rod 43 rotatably connected to the top center of the eccentric wheel 42 swings. Then the limiting rod 44 will relatively move from the limiting groove 432 into the sliding hole 431. At this time, the right bracket 2 can be pulled to adjust the size of the space for placing the mobile phone. After the adjustment is completed, rotate the handle 41 reversely by 180° to reset the handle 41. At this time, under the action of the eccentric wheel 42, the sliding rod 43 will swing and reset, so that the limiting rod 44 can be repositioned in another corresponding limiting groove 432. The side wall of the limiting groove 432 restricts the limiting rod 44 to lock the left bracket 1 and the right bracket 2. In this design method, only by rotating the handle 41, the locking and unlocking of the left bracket 1 and the right bracket 2 can be realized, which is convenient for the user to use and helps to improve the user experience when using.

[0033] Refer to Figures 5 to 7, in order to prevent the clamping of the mobile phone from loosening due to the shaking of the vehicle body when passing through bumpy sections, the following settings are made. A limit ring 5 is provided on the lower side surface of the left bracket 1. The limit ring 5 is integrally circular, and the inner wall of the limit ring 5 is threadedly connected to the outer side wall of the limiting rod 44. A first knob 6 is provided at one end of the limiting rod 44 away from the limit ring 5, and the first knob 6 is fixedly connected to the limiting rod 44 to move synchronously with the limiting rod 44. When the limiting rod 44 is tightened in the limit ring 5, the side surfaces of the limit ring 5 and the first knob 6 close to each other will respectively abut against the opposite side surfaces of the sliding rod 43. When it is necessary to adjust the size of the mobile phone holder for installing the mobile phone, rotate the first knob 6 to screw the limiting rod 44 out of the limit ring 5. At this time, the side surfaces of the limit ring 5 and the first knob 6 close to each other will separate from the opposite side surfaces of the sliding rod 43. At this time, the restriction of the first knob 6 and the limit ring 5 on the sliding rod 43 can be released, and when the handle 41 is rotated, one end of the sliding rod 43 can be driven to swing. After the adjustment is completed, tighten the first knob 6 on the limit ring 5, and the stability of the left bracket 1 and the right bracket 2 can be achieved when no adjustment is required.

[0034] Refer to Figures 5 to 7 , at the same time, in order to further improve the abutting stability of the side surfaces of the limit ring 5 and the first knob 6 close to each other against the opposite side surfaces of the sliding rod 43, a plurality of clamping blocks 433 are provided on the sliding rod 43. The clamping blocks 433 are strip-shaped. The plurality of clamping blocks 433 are distributed at the edge positions of both openings of the limiting groove 432 and are circumferentially distributed along the opening of the limiting groove 432. And the blocks can also be distributed on the side of the sliding hole 431 away from the limiting groove 432. A first card slot 51 is provided on the side surface of the limit ring 5 close to the first knob 6, and a second card slot 61 is provided on the side surface of the first knob 6 close to the limit ring 5. The structural shapes of the first card slot 51 and the second card slot 61 are both adapted to the clamping blocks 433. When the limiting rod 44 is tightened in the limit ring 5, the first card slot 51 and the second card slot 61 respectively supply the corresponding clamping blocks 433 on the opposite two side surfaces of the sliding rod 43 to be inserted. At this time, the side walls of the first card slot 51 and the second card slot 61 restrict the clamping blocks 433, so as to further restrict the position of the sliding rod 43, and try to prevent the sliding rod 43 from swinging and causing the right bracket 2 to move relative to the left bracket 1, thereby trying to prevent the mobile phone from falling and being damaged on the mobile phone holder when passing through bumpy sections.

[0035] Refer to Figures 2 to 5, in order to further prevent the right bracket 2 from moving relative to the left bracket 1, a limiting groove 22 is provided on the protruding portion 21 of the right bracket 2. The orifice of the limiting groove 22 is circular. A plurality of limiting grooves 22 are provided, and the plurality of limiting grooves 22 are equally spaced. Moreover, the distribution direction of the plurality of limiting grooves 22 is along the sliding direction of the right bracket 2, and the plurality of limiting grooves 22 are provided on the side surface of the protruding portion 21 that is in a horizontal plane. At the same time, an insertion rod 72 and a limiting member are provided on the left bracket 1. The insertion rod 72 is a cylindrical long bar-shaped rod. The insertion rod 72 slides vertically relative to the left bracket 1 to be inserted into the limiting groove 22. The limiting member is provided on the left bracket and is connected to the insertion rod 72 to enable the insertion rod 72 to extend into or out of the limiting groove 22.

[0036] The limiting member includes a mounting cylinder 70, a mounting block 71, a telescopic pin 73, a telescopic spring 74, a clamping plate 75, a second knob 76 and a fixing pin 77. Specifically, the mounting cylinder 70 is provided on the upper side surface of the left bracket 1, and the mounting cylinder 70 penetrates into the mounting cavity 11 of the left bracket 1. The opening of the mounting cylinder 70 is disposed opposite to the limiting groove 22. The mounting block 71 is a cylindrical block, and the diameter of the cross-sectional area of the mounting block 71 is slightly smaller than the inner diameter of the mounting cylinder 70. The mounting block 71 is slidably disposed in the mounting cylinder 70, and the sliding direction of the mounting block 71 is along the axial direction of the mounting cylinder 70. The insertion rod 72 is coaxially disposed on the lower side surface of the mounting block 71, and the length direction of the insertion rod 72 extends along the direction away from the mounting block 71. The insertion rod 72 is used to be inserted into one of the plurality of limiting grooves 22. The telescopic pin 73 is also a cylindrical rod, and the telescopic pin 73 is coaxially disposed on the upper side surface of the mounting block 71. The telescopic pin 73 extends away from the mounting block 71 and extends out of the mounting cylinder 70. From the direction parallel to the axis of the mounting block 71, the cross-sectional area of the telescopic pin 73 is smaller than the cross-sectional area of the mounting block 71. The telescopic spring 74 is sleeved on the telescopic pin 73. The structural form of the telescopic spring 74 is a compression spring. One end of the telescopic spring 74 is fixedly connected to the mounting block 71. The clamping plate 75 is fixedly disposed at the upper opening of the mounting cylinder 70. The clamping plate 75 covers the opening of the mounting cylinder 70. The clamping plate 75 extends along the direction perpendicular to the axis of the mounting cylinder 70. The other end of the telescopic spring 74 is fixedly connected to the clamping plate 75. An avoidance hole for the telescopic pin 73 to pass through is provided at the middle position of the clamping plate 75.

[0037] In addition, in other embodiments, the limiting member can also be a bolt. The insertion rod 72 is the side of the bolt rod away from the head, and the insertion rod 72 is extended into or out of the limiting groove 22 by rotating the bolt.

[0038] Refer to Figures 2 to 5The second knob 76 is sleeved on the portion of the telescopic pin 73 extending out of the mounting tube 70. The side of the second knob 76 close to the mounting tube 70 is provided with an avoidance groove 761, which is provided in the form of a through groove, and the through groove is used for placing the card plate 75. The fixing pin 77 is in the shape of a cylindrical rod, and the fixing pin 77 is passed through the portion of the telescopic pin 73 extending out of the mounting tube 70 and the second knob 76, so that the telescopic pin 73 and the second knob 76 move synchronously. Therefore, when the right bracket 2 needs to be moved relative to the left bracket 1, the second knob 76 is first pulled up to pull the insertion rod 72 out of the limit groove 22, and then the second knob 76 is rotated, for example, by 90 degrees, so that the avoidance groove 7 61 is offset from the card plate 75, and then the second knob 76 is loosened. The side of the second knob 76 close to the mounting tube 70 will abut against the card plate 75. At this time, the insertion rod 72 is at a predetermined distance from the limiting slot 22, and the left bracket 1 will not restrict the movement of the right bracket 2. After the adjustment is completed, pull up the second knob 76, and then rotate the second knob 76 to make the avoidance slot 761 coincide with the card plate 75, and loosen the second knob 76 to make the card plate 75 snap into the avoidance slot 761. At this time, the insertion rod 72 will be inserted into the limiting slot 22 to further limit the right bracket 2, thereby further preventing the right bracket 2 from moving relative to the left bracket 1 and causing the mobile phone to fall and break.

[0039] Reference Figures 1 to 7 In this embodiment, in order to facilitate people to rotate the first knob 6 and the second knob 76, the side walls of the first knob 6 and the second knob 76 are provided with extensions 8, and the two extensions 8 are respectively provided on the first knob 6 and the second knob 76. When the first knob 6 or the second knob 76 is rotated, the extensions 8 can be held by the user, so as to facilitate the rotation of the first knob 6 and the second knob 76. In order to prevent the mobile phone from falling during the placement process, a baffle 9 is provided on the rear side of the two installation positions 3 close to each other, and the baffle 9 is used to block the mobile phone.

[0040] Meanwhile, a soft rubber pad 31 is arranged in the installation position 3 . The soft rubber pad 31 is made of a silicone material and can separate the mobile phone from the installation position 3 to prevent the mobile phone from being scratched and damaged by sharp parts on the installation position 3 .

[0041] The implementation principle of a mobile phone holder with a quick unlocking function in an embodiment of the present application is as follows: When it is necessary to adjust the size of the space for placing the mobile phone on the mobile phone holder, lift the second knob 76 upward so that the clamping plate 75 moves out of the avoidance groove 761. At this time, the insertion rod 72 will also be pulled out of the limit groove 22. Then rotate the second knob 76 so that the avoidance groove 761 is staggered from the clamping plate 75. Then release the second knob 76. Under the action of the telescopic spring 74, the side surface of the second knob 76 close to the mounting cylinder 70 will abut against the clamping plate 75, so that there is a predetermined distance between the insertion rod 72 and the limit groove 22, which will not affect the movement of the right bracket 2 relative to the left bracket 1. Then rotate the first knob 6 so that the limit ring 5 and the first knob 6 release the restriction on the sliding rod 43. Then rotate the handle 41 to swing one end of the sliding rod 43 to release the restriction on the limiting rod 44, and then the right bracket 2 can be pulled to adjust the mobile phone installation space. After the adjustment is completed, first rotate the handle 41 in the reverse direction to reset it so that the limiting rod 44 is snapped into the limiting groove 432. Then rotate the second knob 76 so that the avoidance groove 761 corresponds to the clamping plate 75, and under the action of the telescopic spring 74, the insertion rod 72 is inserted into the limit groove 22 for limiting, and then the adjustment of the size of the space for placing the mobile phone can be completed.

[0042] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
