Description

Technical Field

[0001] The invention relates to a mobile phone holder, in particular to a speed reduction linkage type clamping mechanism and a mobile phone holder. Background Art

[0002] A mobile phone holder is a device used to clamp a mobile phone and support it on a desktop, a car center console, etc. In actual applications, the mobile phone is generally clamped only by the clamping claws on both sides of the mobile phone holder. Since the lower end of the mobile phone lacks a holding component, it is difficult to clamp the mobile phone firmly. Even if some mobile phone holders are provided with holding components, these holding components are generally fixed, and only the clamping claws on both sides are used to perform the opening and clamping actions. For mobile phones of different sizes, sometimes it is necessary to lift the mobile phone up to a certain height, or sink it down a certain distance. For example, most of the buttons on the side of the mobile phone are set near the upper edge of the mobile phone. When the buttons on the side of the mobile phone are opposite to the clamping claws, the mobile phone needs to be lifted up to avoid the clamping claws pressing the buttons on the side of the mobile phone. In the prior art, since the holding component of the mobile phone holder cannot be moved, the mobile phone models that can be clamped by the mobile phone holder are limited, which only affects the application scope of the mobile phone holder and is difficult to meet application needs and market demands.

[0029] The present invention is described in more detail below with reference to the accompanying drawings and embodiments.

A longitudinal tooth 211 is formed on the longitudinal support arm 210, and the longitudinal tooth 211 is meshed with the output wheel of the reduction gear 204. When the driving gear 202 rotates forward or reversely, the two horizontal clamping jaws 20 are driven away from or close to each other, and the longitudinal clamping jaw 21 is driven to slide along the longitudinal reduction gear by the cooperation of the driving gear 202, the longitudinal support arm 210 and the reduction gear 204.

[0031] In the above structure, when the driving gear 202 is driven to rotate by an external force, the two horizontal spur racks 201 drive the two horizontal clamping jaws 20 to move away from or approach each other, and at the same time, the driving gear 202, the longitudinal support arm 210 and the reduction gear 204 are linked and coordinated with each other, and the longitudinal clamping jaw 21 is driven to slide along the longitudinal direction with a reduced speed under the action of the reduction gear 204. Compared with the prior art, the present invention can not only use the longitudinal clamping jaw 21 to hold the mobile phone, but also can make the longitudinal clamping jaw 21 slow down to perform the holding action during the clamping process of the horizontal clamping jaw 20, thereby shortening the sliding stroke of the longitudinal clamping jaw 21, making the linkage process more stable and reliable. In addition, compared with the longitudinal clamping jaw structure with a fixed position in the prior art, the present invention is not limited by the clamping position, so it can clamp various models of mobile phones, which better meets the application requirements.

[0033] Furthermore, the longitudinal spur rack 203 is located below the longitudinal support arm 210 .

[0034] In order to make the longitudinal spur rack 203 slide stably longitudinally, in this embodiment, the longitudinal spur rack 203 is in an “H” shape, and the longitudinal spur rack 203 is slidably connected to the bracket 2 .

[0035] In this embodiment, transverse and longitudinal slides are preferably provided on the bracket 2 , specifically, a transverse slide 23 is provided on the bracket 2 , two transverse support arms 200 are both located in the transverse slide 23 , and the transverse support arms 200 are slidably connected to the transverse slide 23 .

[0036] In order to achieve a close fit between the two transverse arms 200, in this embodiment, a straight rod 205 is formed at the end of the transverse arm 200, and the straight rod 205 on the transverse arm 200 is located on the outside of the transverse straight rack 201 on the other transverse arm 200, and the straight rod 205 is slidably connected to the transverse straight rack 201.

[0037] In order to play a limiting role, in this embodiment, stop edges 230 are respectively formed at the two side edges of the transverse slide 23 , and the two stop edges 230 are respectively arranged above the two straight rods 205 .

[0038] As a preferred embodiment, a longitudinal slide 24 is provided on the bracket 2, the longitudinal support arm 210 and the longitudinal spur rack 203 are both located in the longitudinal slide 24, and the longitudinal support arm 210 and the longitudinal spur rack 203 are both slidably connected to the longitudinal slide 24.

[0039] In order to limit the sliding stroke of the longitudinal support arm 210, in this embodiment, a guide rod 240 is provided in the longitudinal slide 24, and a slot 213 is opened on the longitudinal support arm 210. The slot 213 extends along the length direction of the longitudinal support arm 210. The guide rod 240 passes through the slot 213 and the two are slidably connected.

[0040] In order to better describe the technical solution of the present invention, the present invention also discloses a mobile phone holder, Figures 1 to 10 As shown, it includes a shell 1, in which the deceleration linkage clamping mechanism is arranged, two transverse clamping jaws 20 and the longitudinal clamping jaws 21 pass through the shell 1 respectively, and a wireless charging module 10 and a panel 11 are arranged on the shell 1, and the panel 11 covers the wireless charging module 10.

[0041] This embodiment preferably has a lighting effect, specifically, a PCB board 12 is provided on the shell 1, the wireless charging module 10 is electrically connected to the wireless charging module 10, a plurality of LED lights 13 are provided on the PCB board 12, and a light-transmitting portion 14 is formed at the edge of the panel 11, the light-transmitting portion 14 surrounds the panel 11, and a plurality of LED lights 13 are evenly distributed along the light-transmitting portion 14.

[0042] As a preferred embodiment, the bracket 2 is provided with a driving mechanism 25 for driving the driving gear 202 to operate.

[0043] In actual applications, for some electric mobile phone holders, they rely on a motor to drive two lateral clamping jaws to move horizontally to clamp the mobile phone. When the mobile phone holder loses power, the reaction force that its internal reduction gears and other mechanisms can withstand is large, resulting in the two lateral clamping jaws cannot be manually opened, making it difficult to take out the mobile phone in the power-off state.

[0044] In order to solve the above technical problems, in this embodiment, combined with Figure 8 and Fig. 9 As shown, the driving mechanism 25 includes a motor 250 and a gear plate 251, and the motor 250 drives the gear plate 251 to rotate. A spring 252 is sandwiched between the gear plate 251 and the housing 1. The gear plate 251 is coaxially aligned with the driving gear 202. A first annular ratchet 253 is formed on the end face of the gear plate 251, and a second annular ratchet 254 is formed on the end face of the driving gear 202. The first annular ratchet 253 and the second annular ratchet 254 are engaged with each other by the elastic force applied by the spring 252.

[0045] In the above structure, under the locking action of the first annular ratchet 253 and the second annular ratchet 254, and the abutting cooperation of the spring 252, the gear plate 251 and the driving gear 202, the gear plate 251 can be used to drive the driving gear 202 to rotate. When the mobile phone holder is in a power-off state, it is only necessary to pry open the two horizontal clamping claws 20. At this time, the driving gear 202 only needs to overcome the elastic force of the spring 252 and the locking force between the first annular ratchet 253 and the second annular ratchet 254, so that the driving gear 202 can rotate relative to the gear plate 251, thereby facilitating the removal of the mobile phone in the case of power failure.

[0046] In order to achieve power transmission, in this embodiment, a threaded shaft 255 is provided on the output shaft of the motor 250 , and the threaded shaft 255 and the gear plate 251 are meshed in sequence through a transmission gear 256 .

[0047] This embodiment provides an accommodation space for the gear plate 251 . Specifically, a circular recess 15 is formed on the housing 1 , and the gear plate 251 is accommodated in the circular recess 15 .

[0048] In this embodiment, see Figure 4 and Figure 5, the longitudinal teeth 211 are located at the left edge of the opening 212. Based on the above structure, when the driving gear 202 drives the two transverse jaws 20 to open, the driving gear 202 drives the longitudinal spur rack 203 to translate in the direction close to the transverse jaws 20, and at the same time, the reduction gear 204 drives the longitudinal support arm 210 to decelerate and translate, and the longitudinal support arm 210 has the same translation direction as the longitudinal spur rack 203, that is, when the two transverse jaws 20 are opened, the longitudinal jaw 21 performs a lifting action, and when the two transverse jaws 20 are clamped, the longitudinal jaw 21 performs a descending action.

[0049] However, in another embodiment of the present invention, see Fig.10 , the longitudinal teeth 211 are located at the right edge of the opening 212. Based on the above structure, when the driving gear 202 drives the two transverse jaws 20 to open, the driving gear 202 drives the longitudinal spur rack 203 to translate in the direction close to the transverse jaws 20, and at the same time, the reduction gear 204 drives the longitudinal support arm 210 to decelerate and translate, and the longitudinal support arm 210 and the longitudinal spur rack 203 have opposite translation directions, that is, when the two transverse jaws 20 are opened, the longitudinal jaw 21 performs a descending action, and when the two transverse jaws 20 are clamped, the longitudinal jaw 21 performs a lifting action.

[0050] It can be seen that in order to meet the action requirements in different application scenarios, the longitudinal teeth 211 can be located at the left edge or the right edge of the opening 212. Both of these application modes belong to the protection scope of the present invention.

[0051] In this embodiment, combined with Figures 11 to 13 As shown, a supporting mechanism 6 is provided at the bottom of the shell 1, and the supporting mechanism 6 includes a vertical rod 60 and a lock shell 61. A hook-shaped portion 62 is formed at the bottom of the vertical rod 60. The vertical rod 60 passes through the lock shell 61 and the two are slidably connected. The lock shell 61 is provided with a locking mechanism for fastening the lock shell 61 and the vertical rod 60.

[0052] Furthermore, the locking mechanism includes a slider 63 and a locking spring 64, a vertical rod tooth 600 is formed on the side of the vertical rod 60, a locking tongue 630 is formed on the slider 63, and the locking spring 64 abuts between the lock housing 61 and the slider 63, and the locking tongue 630 is engaged with the vertical rod tooth 600 by the elastic force applied by the locking spring 64.

[0053] As a preferred embodiment, the slider 63 and the locking spring 64 are both arranged inside the lock shell 61, the end of the slider 63 passes through the lock shell 61, a through hole 631 is opened on the slider 63, the vertical rod 60 passes through the through hole 631, the lock tongue 630 is located on the inner side of the through hole 631, and two oppositely arranged arc-shaped legs 65 are formed on the outer side of the lock shell 61, and the arc-shaped legs 65 are connected to the lock shell 61 through a connecting arm 66.

[0054] Under the action of the above-mentioned supporting mechanism 6, the hook-shaped portion 62 can be used to stably and reliably clamp the mobile phone holder to the car's air outlet grille. At the same time, under the action of the locking mechanism, the clamping width can be adjusted, thereby being suitable for car air outlet grilles of various widths, greatly improving the compatibility of the product and better meeting market demand.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
