[0014] Compared with the prior art, the utility model provides a bracket base and a bracket assembly, which has the following advantages:

[0015] 1. The embodiment of the utility model provides a bracket base, which realizes the rotational connection between the connecting part and the fixed part by setting a rotating shaft inside. In the existing structural design industry, the rotating shaft is a standard part. Compared with the various complex shaft hole connections designed in the existing products to realize the rotational connection, this solution only needs to complete the connection between the first rotating part and the second rotating part of the rotating shaft and the connecting part and the fixed part. It does not need to spend time to assemble the rotating structure. The structure is simple and the production efficiency is high. Specifically, the connecting part is used to connect the external mobile phone bracket; the shell assembly serves as a protective shell of the overall structure, provides protection for the internal structure, and provides an installation foundation for the rotating assembly and other components; the fixed part provides a stable foundation for the entire bracket base, ensuring that the bracket base can be firmly fixed in the required position.

[0016] 2. In the embodiment of the utility model, the first rotating part is connected and fixed to the connecting part through the first transition piece, that is, when the first rotating part and the second rotating part rotate relative to each other, the first transition piece and the rotating part rotate together. At this time, in addition to the rotation restriction of the rotation itself, a partial area is rotatably arranged in the rotating track, thereby ensuring the rotation smoothness between the connecting part and the shell assembly. At the same time, the rotating track can limit the first transition piece located in the track to prevent it from detaching from the shell assembly, which is beneficial to enhancing the structural stability of the bracket base; at the same time, the first transition piece and the first rotating part are adaptively connected through the matching hole, thereby ensuring that the connection between the connecting part and the rotating assembly is more stable, reliable and easy to assemble.

[0017] 3. In the embodiment of the utility model, the first rotating part is matched with the matching hole and the matching groove at the same time, that is, the first rotating part is in direct contact with the connecting part and the first transition piece at the same time, and the force during rotation will be dispersed to the two parts, which can effectively reduce the wear rate. Specifically, the matching hole is set as a through hole, and the first rotating part can be easily inserted and fixed through the matching of the matching hole and the first matching groove, which simplifies the assembly process; the precise matching of the matching hole and the first matching groove ensures the stable connection between the first rotating part and the connecting part, reducing the shaking or loosening phenomenon that may occur during use.

[0018] 4. In the embodiment of the utility model, the second matching groove is connected with the second rotating part, thereby ensuring a stable connection between the second rotating part and the fixed part, and reducing the wear caused by direct contact with the rotating shaft.

[0019] 5. In the embodiment of the utility model, by providing a through installation channel, the installation process of the locking piece is simplified, so that the locking piece can be more easily installed on the fixing part, while ensuring the stable fixation of the locking piece and improving the stability of the bracket base. The design of the fixing section and the avoidance section ensures that the locking piece can be stably fixed on the fixing part, avoiding the movement or falling off of the locking piece during use; the design of the clamping boss ensures that the locking piece is clamped in the fixing section, improving the stability of the locking piece and reducing the risk of the locking piece loosening.

[0020] 6. In the embodiment of the utility model, by adding a limiting protrusion to stably fix the locking piece, the shaking or loosening caused by unstable locking can be reduced, thereby extending the service life of the product. Specifically, the design of the limiting protrusion ensures that the locking piece is stably maintained in the fixed section, reducing the risk of the locking piece loosening; the existence of the guide surface makes it easier for the locking piece to slide along the inner wall of the fixed section and be installed in place, reducing the difficulty of assembly; the abutment surface ensures that the position of the locking piece in the fixed section is fixed, preventing the locking piece from moving or falling off during use.

[0021] 7. In the embodiment of the utility model, the assembly process of the shell assembly is simplified by the snap-fit ​​structure, thereby reducing the production cost and time consumption; the design of the snap-fit ​​and rotational connection ensures a stable connection between the shell assembly and the rotating assembly, thereby reducing the shaking or loosening that may occur during use; the rotational connection between the first transition piece and the inner shell ensures that the rotational movement between the connecting part and the rotating assembly is smoother.

[0022] 8. In the embodiment of the utility model, the design of the limiting structure not only simplifies the assembly process of the housing assembly, but also improves the stability and service life of the product, and enhances the user experience. Specifically, the design of the annular protrusion, the first limiting protrusion, the first annular step and the first limiting notch simplifies the assembly process between the outer housing and the inner housing, ensuring a stable connection between them; the cooperation between the second limiting protrusion and the second limiting notch ensures a stable connection between the inner housing and the fixing part; the cooperation between the third limiting protrusion and the third limiting notch ensures a stable connection between the second transition piece and the fixing part.

[0023] 9. In the embodiment of the utility model, the first mounting boss cooperates with the limiting groove to further enhance the connection stability between the first transition piece and the connecting part. The second annular step is designed so that the outer shell can be slidably mounted on the connecting part, further improving the rotation stability and the compactness of the overall structure.

[0024] 10. The embodiment of the utility model also provides a bracket assembly, which has the same beneficial effects as the above-mentioned bracket base, which will not be described in detail here.

[0042] It should be noted that the terms "first" and "second" etc. in the specification and claims of the present utility model are used to distinguish different objects rather than to describe a specific order.

[0043] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0044] In the present invention, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0045] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this utility model can be understood according to specific circumstances.

[0046] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0047] Please combine Figure 1 and Figure 2 The first embodiment of the utility model provides a bracket base 10, which is used to fix the electronic device bracket. The bracket base 10 includes a connecting part 1, a shell component 2, a rotating component 3 and a fixing part 4; the shell component 2 is installed on the fixing part 4, the rotating component 3 is arranged in the shell component 2, and the rotating component 3 includes a rotating shaft 31; the rotating shaft 31 includes a first rotating part 311 and a second rotating part 312 that are rotatably connected. One end of the connecting part 1 extends into the shell component 2 and is connected to the first rotating part 311, and the second rotating part 312 is connected to the fixing part 4. The connecting part 1 and the fixing part 4 are rotatably connected through the rotating shaft 31.

[0048] It can be understood that the rotational connection between the connecting part 1 and the fixing part 4 is achieved by setting a rotating shaft 31 inside. In the existing structural design industry, the rotating shaft 31 is a standard part. Compared with the various complex shaft hole connections designed in existing products to achieve rotational connection, this solution only needs to complete the connection between the first rotating part 311 and the second rotating part 312 of the rotating shaft 31 and the connecting part 1 and the fixing part 4. It does not need to spend time to assemble the rotating structure. The structure is simple and the production efficiency is high. Specifically, the connecting part 1 is used to connect the external mobile phone holder; the shell assembly 2 serves as a protective shell of the overall structure, provides protection for the internal structure, and provides an installation foundation for the rotating assembly 3 and other components; the fixing part 4 provides a stable foundation for the entire bracket base 10, ensuring that the bracket base 10 can be firmly fixed in the desired position.

[0049] As a feasible implementation, the rotating shaft 31 uses a damping rotating shaft 31. It can be understood that the damping rotating shaft 31 can provide a smooth rotation experience, so that the user can adjust the angle of the bracket base 10 more smoothly; the damping rotating shaft 31 can better control the resistance during rotation, ensuring that the bracket base 10 can be stably maintained after being adjusted to the desired position, and will not change position due to slight external force.

[0050] It should be noted that the common rotating shaft 31 or the damping rotating shaft 31 are both existing standard parts.

A matching hole 321 is provided on the first transition piece 32, and the inner wall of the matching hole 321 is matched with the outer peripheral surface of the first rotating part 311. The first rotating part 311 extends into the matching hole 321 and is connected to the connecting part 1 through the first transition piece 32.

[0052] It can be understood that the first rotating part 311 is connected and fixed to the connecting part 1 through the first transition piece 32, that is, when the first rotating part 311 and the second rotating part 312 rotate relative to each other, the first transition piece 32 and the rotating part rotate together. At this time, in addition to the rotation restriction of the rotation itself, a partial area is rotatably arranged in the rotating track 221, thereby ensuring the rotation smoothness between the connecting part 1 and the shell assembly 2. At the same time, the rotating track 221 can limit the first transition piece 32 located in the track to prevent it from detaching from the shell assembly 2, which is beneficial to enhancing the structural stability of the bracket base 10; at the same time, the first transition piece 32 and the first rotating part 311 are adaptively connected through the matching hole 321, thereby ensuring that the connection between the connecting part 1 and the rotating assembly 3 is more stable, reliable and easy to assemble.

[0053] As a feasible implementation, the cross-sections of the first rotating portion 311 and the second rotating portion 312 are non-circular. It can be understood that the design of the non-circular cross-section can prevent the first rotating portion 311 and the second rotating portion 312 from rotating unnecessarily during the rotation process. For example, the first rotating portion 311 and the matching hole 321 can be better connected stably through this design.

[0054] Optionally, the cross-sections of the first rotating portion 311 and the second rotating portion 312 may be elliptical, polygonal, or irregular.

[0055] As a feasible implementation, the mating hole 321 is a through hole, and a first mating groove 121 is also provided corresponding to the through hole on the connecting part 1. The inner wall of the first mating groove 121 is adapted to the outer peripheral surface of the first rotating part 311, and a partial area of ​​the first rotating part 311 passes through the mating hole 321 and cooperates with the first mating groove 121.

[0056] It can be understood that the first rotating part 311 is matched with the matching hole 321 and the matching groove at the same time, that is, the first rotating part 311 is in direct contact with the connecting part 1 and the first transition piece 32 at the same time, and the force during rotation will be dispersed to the two parts, which can effectively reduce the wear rate. Specifically, the matching hole 321 is set as a through hole, and the first rotating part 311 can be easily inserted and fixed through the matching of the matching hole 321 and the first matching groove 121, which simplifies the assembly process; the precise matching of the matching hole 321 and the first matching groove 121 ensures the stable connection between the first rotating part 311 and the connecting part 1, and reduces the shaking or loosening phenomenon that may occur during use.

[0057] See also Figure 4 As a feasible implementation, the rotating assembly 3 also includes a second transition piece 33, on which a second matching groove 331 is provided, the inner wall of the second matching groove 331 is adapted to the outer peripheral surface of the second rotating part 312, and the second rotating part 312 is connected to the fixed part 4 through the second transition piece 33.

[0058] It can be understood that the second matching groove 331 is connected to the second rotating portion 312 , thereby ensuring a stable connection between the second rotating portion 312 and the fixing portion 4 , and reducing wear caused by direct contact with the rotating shaft 31 .

[0059] Specifically, the rotating shaft 31 is located between the first transition piece 32 and the second transition piece 33 , and is connected to the connecting portion 1 and the fixing portion 4 through the first transition piece 32 and the second transition piece 33 , respectively.

[0060] Please combine Figure 4 and Figure 5 As a feasible implementation, the fixing portion 4 includes a through installation channel 41, the installation channel 41 includes a connected fixing section 411 and an avoidance section 412, and a locking piece 42 is also provided in the fixing portion 4, the locking piece 42 passes through the fixing section 411 and a part of the area passes through the avoidance section 412 and then passes out, and a part of the area is installed and fixed to the fixing section 411; a clamping boss 332 is provided on a side of the second transition piece 33 close to the fixing portion 4 corresponding to the fixing section 411, and when the second transition piece 33 is installed on the fixing portion 4, the clamping boss 332 extends into the fixing section 411 and clamps the locking piece 42.

[0061] It can be understood that by providing the through installation channel 41, the installation process of the locking member 42 is simplified, so that the locking member 42 can be more easily installed on the fixing portion 4, while ensuring the stable fixation of the locking member 42, and improving the stability of the bracket base 10. The design of the fixing section 411 and the avoidance section 412 ensures that the locking member 42 can be stably fixed on the fixing portion 4, avoiding the movement or falling off of the locking member 42 during use; the design of the pressing boss 332 ensures that the locking member 42 is pressed in the fixing section 411, improving the stability of the locking member 42 and reducing the risk of the locking member 42 loosening.

[0062] As a feasible implementation, the locking member 42 is a hexagonal bolt, the fixing section 411 is a hexagonal channel corresponding to the hexagonal bolt, the avoidance section 412 is a light hole section or a threaded internal thread section that matches the thread of the hexagonal bolt, and at least part of the external thread section of the hexagonal bolt is exposed after passing through the avoidance section 412, which is used to install and fix the bracket base 10 in the external environment. It can be understood that the hexagonal bolt is selected in this embodiment to adapt to the vehicle designed with a threaded fixing hole. In other embodiments, the locking member 42 can also be an adhesive, a magnetic suction member, or a clamping member.

[0063] See also Figure 6 As a feasible implementation, a limiting protrusion 413 is provided on the inner wall of the fixed section 411, and the limiting protrusion 413 includes a guide surface 4131 and a supporting surface 4132. The supporting surface 4132 is located on the side of the guide surface 4131 close to the avoiding section 412. The guide surface 4131 connects the inner wall of the fixed section 411 and the supporting surface 4132, and a partial area of ​​the locking member 42 is against the supporting surface 4132 after passing through the guide surface 4131.

[0064] It can be understood that by adding the limiting protrusion 413 to stably fix the locking member 42, the shaking or loosening caused by unstable locking can be reduced, thereby extending the service life of the product. Specifically, the design of the limiting protrusion 413 ensures that the locking member 42 is stably maintained in the fixing section 411, reducing the risk of the locking member 42 loosening; the existence of the guide surface 4131 makes it easier for the locking member 42 to slide along the inner wall of the fixing section 411 and be installed in place, reducing the difficulty of assembly; the abutting surface 4132 ensures that the position of the locking member 42 in the fixing section 411 is fixed, preventing the locking member 42 from moving or falling off during use.

[0076] As a feasible implementation, a side of the connecting rib 125 close to the first mounting boss 122 is provided with an avoidance groove 126. It can be understood that the design of the avoidance groove 126 avoids interference between the connecting rib 125 and the first matching groove 121, ensuring smooth assembly between the first mounting boss 122 and the first transition piece 32.

[0077] As a feasible implementation, one end of the connecting arm 11 and the connecting plate 12 is provided with a connecting structure for mounting an external electronic device bracket. Specifically, in this embodiment, the connecting structure is a universal connecting ball for universal connection with the external electronic device bracket.

[0078] See also Figures 1 to 10 In this embodiment, the assembly process of the bracket base 10 is briefly described as follows:

[0079] The first transition piece 32 is installed into the inner shell 22. Specifically, the outer periphery of the first transition piece 32 is installed into the rotating track 221 on the inner shell 22. During installation, the first transition piece 32 enters from the bottom of the inner shell 22. Here, the bottom of the inner shell 22 refers to the end of the inner shell 22 away from the connecting portion 1 after installation. During the entry process, the first transition piece 32 avoids the second limiting protrusion 224 on the inner shell 22 through the avoiding notch 323.

[0080] The inner shell 22 equipped with the first transition piece 32 is installed into the outer shell 21 from the top of the outer shell 21 to obtain a first assembly; the top of the outer shell 21 here refers to the end of the outer shell 21 close to the connecting portion 1 after the installation is completed, and after the installation is completed, the first annular step 222 is abutted against the annular protrusion 211, and the first limiting protrusion 212 is located in the first limiting notch 223;

[0081] Place the connecting plate 12 of the connecting part 1 on the top of the first component and align them so that the first mounting boss 122 matches the limiting groove 322, and then lock the first transition piece 32 and the connecting part 1 with a screw member, thereby achieving the connection between the first component and the connecting part 1;

[0082] The locking piece 42 is installed on the fixing part 4 through the installation channel 41, the second transition piece 33 is placed on the fixing part 4, and the clamping boss 332 presses the locking piece 42 in the fixing section 411, and the fixing part 4 and the second transition piece 33 are fixed to the inner shell 22 together by the threaded part to complete the overall assembly.

[0083] The second embodiment of the utility model provides a bracket assembly, including an electronic device bracket and the bracket base as described above, wherein the electronic device bracket is arranged on the bracket base. It can be understood that the bracket assembly has the same beneficial effects as the bracket base, which will not be described in detail here.
