Technical Field

[0001] The utility model relates to the technical field of mobile phone brackets, in particular to a multi-angle adjustable bracket and a mobile phone case. Background Art

[0002] The popularization of electronic products has greatly enriched people's life and work styles. Among them, mobile phones and tablet computers are essential electronic products in daily life. To further improve the user experience, various brackets have emerged. They not only provide users with a stable support platform, enabling the hands to be liberated when watching videos, making video calls, reading documents, or doing creative work for a long time, but also effectively relieve the neck and hand fatigue caused by looking down or holding the device for a long time by adjusting the angle and height.

[0003] In the current market, many brackets are ingeniously integrated with the mobile phone case, greatly improving the convenience of use. However, such designs often have a single function and do not involve realizing the horizontal and vertical switching support of electronic products. Although there are some rotating bracket structures, they have more components, complex structures, higher costs, and also increase the difficulty of maintenance. Content of the Utility Model

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the utility model is to provide a multi-angle adjustable bracket and a mobile phone case, adopting the following technical solutions:

[0005] A multi-angle adjustable bracket, comprising:

[0006] A fixed gear, on the outer side wall of which an inner guide rail is provided, and tooth teeth are provided on at least one side of the inner guide rail of the fixed gear;

[0007] A collar, on which an outer guide rail is provided, and tooth teeth are provided on at least one side of the outer guide rail of the collar;

[0008] And a plurality of transmission gears, on the outer side wall of which a guide plate is provided around, and tooth teeth are provided on at least one side of the guide plate of the transmission gear;

[0009] A plurality of the above-mentioned transmission gears are arranged between the fixed gear and the collar, and the transmission gears are meshed with the fixed gear and the collar through tooth teeth, and the guide plate is embedded in the inner guide rail and the outer guide rail; the collar is damped and hinged with a support member so as to be able to open or close.

[0010] In this technical solution, the fixed gear is stationary. The fixed gear, the transmission gear, and the collar form a planetary gear structure. By rotating the collar, the support member can be rotated around the fixed gear. The meshing of the teeth can make the rotation of the collar more stable. The engagement of the transmission gear with the collar and the fixed gear can provide corresponding frictional force to prevent the collar from rotating randomly. The structure of the guide plate engaging with the inner and outer guide rails makes the overall bracket thin and light, and there is no need to additionally set a gear bracket for support. When in use, the fixed gear is fixedly connected to the object to be supported, the collar is rotated to an appropriate angle, the support member is opened and placed on a plane, and the object to be supported is supported. This structure has few components, simple assembly, convenient operation, and good practicability.

[0011] For further improvement, the above-mentioned fixed gear includes an upper tooth plate and a lower tooth plate. The upper tooth plate and the lower tooth plate are fixedly connected in a stacked manner up and down, and the edges of the upper tooth plate and the lower tooth plate are spaced apart up and down to form the above-mentioned outer guide rail.

[0012] In this technical solution, the purpose of setting the fixed gear with two upper and lower tooth plates is to facilitate assembly. To provide an assembly method for easy understanding, first embed several transmission gears in the outer guide rail, then mesh the teeth of the lower tooth plate with the lower half of several transmission gears, and finally fasten the upper tooth plate on the lower tooth plate, thus completing the assembly. The steps are simple, and it is also convenient for subsequent maintenance and component replacement.

[0013] For further improvement, the above-mentioned transmission gears are provided with teeth on both the upper and lower sides of the guide plate.

[0014] In the above technical solution, having teeth on both the upper and lower sides makes the rotation of the bracket more stable. And after installation, the central engagement of the guide plate also makes the overall structure more stable and not easily damaged by external influences.

[0015] For further improvement, the side of the above-mentioned support member away from the hinge is provided with a notch.

[0016] In this technical solution, the purpose of setting the notch is to facilitate the opening of the support member. At the same time, when the bracket is supporting, the notch can also be used as a supporting part to support on the plane, making the bracket support stable.

[0017] For further improvement, the middle part of the above-mentioned support member is provided with a hollow part.

[0018] For further improvement, the edge of the above-mentioned hollow part coincides with the edge of the collar up and down.

[0019] In this technical solution, through the hollow part, the fixed gear and the transmission gear can be directly seen, which is convenient for observing whether the gear structure is accurately meshed, facilitating maintenance, and at the same time having a mechanical aesthetic feeling.

[0020] For further improvement, the side of the above-mentioned support member close to the collar is provided with a groove.

[0021] In this technical solution, the function of the groove is to reduce the material used and lower the cost. In addition, the groove is also used to install a magnet so that when the support member is closed, it fits firmly with the collar.

[0022] For further improvement, a connecting portion is provided on a side of the fixed gear away from the support member.

[0023] In this technical solution, the connecting portion is used to fixedly connect the mobile phone case so that the fixed gear is fixed relative to the mobile phone. The connecting portion includes, but is not limited to, being fixedly connected to the mobile phone case by magnetic attraction or gluing, or directly fixedly connected to the mobile phone.

[0024] The present utility model further provides a mobile phone case, on the back of which a multi-angle adjustable bracket having the above-mentioned structure is fixedly provided, and the connecting portion is fixedly connected to the back of the mobile phone. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] As Figures 1-3 shown, the present application provides a multi - angle adjustable bracket, including a fixed gear 1, a collar 2, and a plurality of transmission gears 3. Specifically, an inner guide rail 11 is provided on the outer side wall of the fixed gear 1, and the fixed gear 1 is provided with teeth on at least one side of the inner guide rail 11; an outer guide rail 21 is provided on the collar 2, and the collar 2 is provided with teeth on at least one side of the outer guide rail 21; a plurality of transmission gears 3 are provided with a guide plate 31 around the outer side wall, and the transmission gears 3 are provided with teeth on at least one side of the guide plate 31; a plurality of transmission gears 3 are arranged between the fixed gear 1 and the collar 2, and the transmission gears 3 are meshed with the fixed gear 1 and the collar 2 through teeth, and the guide plate 31 is embedded in the inner guide rail 11 and the outer guide rail 21; the collar 2 is damped and hinged with a support member 4 so as to be able to open or close.

[0042] In a specific embodiment, the collar 2 is in a circular ring shape, with evenly arranged teeth on its inner side wall, its center is hollowed out, and a fixed gear 1 is installed. Nine transmission gears 3 are distributed around the fixed gear 1, forming a planetary gear structure. By rotating the collar 2, the rotation of the support member 4 around the fixed gear 1 is realized, and the meshing of the teeth can make the rotation of the collar 2 more stable.

[0043] Furthermore, the engagement of the transmission gears 3 with the collar 2 and the fixed gear 1 can provide corresponding frictional force to prevent the collar 2 from rotating randomly. The above - mentioned structure makes the transmission gears 3 not need to be supported by an additional gear bracket by embedding the guide plate 31 in the inner guide rail 11 and the outer guide rail 21, and the overall structure is more lightweight. When in use, the fixed gear 1 is fixedly connected with the object to be supported, the collar 2 is rotated to an appropriate angle, the support member 4 is opened and placed on a plane to support the object to be supported. This structure has few components, simple assembly, convenient operation, and good practicability.

[0044] As shown Figure 5 in the figure, the fixed gear 1 includes an upper tooth plate 12 and a lower tooth plate 13. The upper tooth plate 12 and the lower tooth plate 13 are fixedly connected in an up-and-down stacked manner, and the edges of the upper tooth plate 12 and the lower tooth plate 13 are spaced apart vertically, forming an outer guide rail 21. Tooth teeth are provided on both the upper and lower sides, making the rotation of the bracket more stable. After installation, the middle part of the guide plate 31 is fitted, making the overall structure more stable and not easily damaged by external influences.

[0045] In a specific embodiment, tooth teeth are provided on both the upper and lower sides of the outer guide rail 21, tooth teeth are provided on both the upper and lower sides of the guide plate 31, and tooth teeth are provided on both the upper and lower sides of the inner guide rail 11.

[0046] For ease of understanding, a bracket assembly method will be introduced below. Please refer to Figure 3 . During installation, first place the lower tooth plate 13 in the middle of the collar 2, and install the transmission gear 3 between the collar 2 and the lower tooth plate 13. Among them, one side of the guide plate 31 is inserted into the outer guide rail 21, and the other side overlaps on the upper surface of the lower tooth plate 13, and it is ensured that the tooth teeth of the transmission gear 3 are respectively engaged with the tooth teeth on the inner side wall of the collar 2 and the tooth teeth of the lower tooth plate 13. After installing the transmission gear 3, cover the upper tooth plate 12 on the upper end of the guide plate 31 and fixedly connect it to the lower tooth plate 13, and the tooth teeth of the upper tooth plate 12 are engaged with the tooth teeth on the upper side of the guide plate 31 of the transmission gear 3. Thus, the installation is completed. The installation steps are simple, easy to disassemble, and convenient for subsequent maintenance and component replacement.

[0047] As shown Figures 1-2 in the figure, a notch 41 is provided on the side of the support 4 away from the hinge. This notch 41 facilitates the opening of the support 4.
