Description

Technical Field

[0001] This utility model relates to the field of gimbal camera technology, and in particular to a lens housing and gimbal for use in a gimbal. Background Technology

[0002] In common gimbal cameras, the gimbal's support arm mechanism includes a base, a pitch axis motor mount connected to the base via a cantilever for mounting the pitch axis motor, and a lens housing driven by the pitch axis motor. This lens housing is typically designed as a cylindrical structure to mount the roll axis motor and the lens module driven by it. During wiring, the coaxial cable originates from the image sensor circuit board of the lens module, passes through the roll axis motor, runs along the inner wall of the lens housing to the pitch axis motor, and finally exits from the lens housing after passing through the pitch axis motor. Thus, when the roll axis motor operates and drives the lens module to rotate, the coaxial cable between the roll axis motor and the pitch axis motor will oscillate inside the lens housing due to torque, affecting the normal rotation of the lens module and causing product instability. Simultaneously, the rotating parts of the motor may collide with the coaxial cable, affecting its normal rotation, and may even pull on the coaxial cable, causing the coaxial cable terminals to detach or the coaxial cable to break, affecting signal transmission. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a lens housing and gimbal that can effectively fix the internal coaxial line for the gimbal.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A lens housing for a gimbal includes: a cylindrical housing; a lens element disposed at the front end of the cylindrical housing; an end cap disposed at the rear end of the cylindrical housing; a first motor connection position for mounting a pitch axis motor, formed in the middle of the side wall of the cylindrical housing; a first motor mounting position for mounting a roll axis motor, formed inside the rear end of the cylindrical housing; a first cable constraint member formed on the inner side wall of the cylindrical housing near the first motor mounting position; and a second cable constraint member disposed on the end face of the pitch axis motor facing the interior of the cylindrical housing and protruding inside the cylindrical housing, or disposed on the inner side wall of the cylindrical housing near the edge of the first motor connection position.

[0006] A gimbal includes: a support arm mechanism, comprising a base, a pitch axis motor mount connected to the base via a cantilever, and a lens housing as described above; a pitch axis motor mounted in the pitch axis motor mount, its rotor connected to the lens housing; a roll axis motor mounted inside the cylindrical housing of the lens housing, its rotor connected to a lens module mounted inside the cylindrical housing; a coaxial cable extending from the image sensor board of the lens module, passing through the roll axis motor, being constrained and positioned by a first cable constraint member, then attaching to the inner wall of the cylindrical housing, extending to a second cable constraint member, and being constrained and positioned by the second cable constraint member before being introduced into the pitch axis motor.

[0007] The beneficial technical effects of this utility model are as follows: By setting the first cable constraint member and the second cable constraint member, the coaxial cable passes through the roll axis motor and is constrained and positioned by the first cable constraint member, and is constrained and positioned by the second cable constraint member before being introduced into the pitch axis motor. In this way, the two ends of the coaxial cable between the roll axis motor and the pitch axis motor can be fixed, so that this coaxial cable can be firmly attached to the inner wall of the cylindrical housing without swinging when the roll axis motor rotates, thus avoiding affecting the normal operation of the lens module. At the same time, it can prevent the rotating part of the motor from colliding with the coaxial cable and affecting the normal rotation of the motor, and prevent the coaxial cable from being pulled and causing the coaxial cable terminals to fall off or the coaxial cable to break, thus affecting signal transmission and ensuring the working stability of the gimbal camera.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0013] It should be understood that, in the description of this utility model, unless otherwise expressly specified and limited, the term "plural" means two or more; the terms "first," "second," ... are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated; the terms "installation" and "connection" should be interpreted broadly, for example, "connection" can be a fixed connection, a detachable connection, or an integral connection, and can be a direct connection or an indirect connection through an intermediate medium; the terms "front," "rear," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation or be constructed in a specific orientation.

[0014] The lens housing disclosed in this utility model serves as part of the support arm structure of a gimbal, and is used for mounting components such as the lens module of the gimbal camera and the roll axis motor of the gimbal. The lens housing is connected to and driven by the pitch axis motor of the gimbal, which in turn rotates the lens module to achieve pitch operation. The lens module is connected to and driven by the roll axis motor to achieve roll operation.

[0015] See Figures 1 to 4 In some preferred embodiments, the lens housing 10 includes a cylindrical housing 11, a lens 12 disposed at the front end of the cylindrical housing 11, and an end cap 13 disposed at the rear end of the cylindrical housing 11. A first motor connection position 110 for connecting a pitch axis motor 20 is formed in the middle of the side wall of the cylindrical housing 11, and a first motor mounting position 111 for mounting a roll axis motor 30 is formed inside the rear end of the cylindrical housing 11. A first cable constraint member 112 is formed on the inner side wall of the cylindrical housing 11 near the first motor mounting position 111, and a second cable constraint member 113 is disposed on the end face of the pitch axis motor 20 facing the inside of the cylindrical housing 11 and protrudes inside the cylindrical housing 11. Thus, through the setting of the first cable constraint member 112 and the second cable constraint member 113, the coaxial cable passes through the roll axis motor 30 and is constrained and positioned by the first cable constraint member 112, and is constrained and positioned by the second cable constraint member 113 before being introduced into the pitch axis motor 20. This fixes both ends of the coaxial cable between the roll axis motor 30 and the pitch axis motor 20, so that this section of the coaxial cable can be firmly attached to the inner wall of the cylindrical housing 11, and will not swing when the roll axis motor 30 rotates, avoiding affecting the normal operation of the lens module. At the same time, it can prevent the rotating part of the motor from colliding with the coaxial cable and affecting the normal rotation of the motor, and prevent the coaxial cable from being pulled and causing the coaxial cable terminals to fall off or the coaxial cable to break, thus affecting signal transmission and ensuring the working stability of the gimbal camera.

[0016] In the embodiment shown in the accompanying drawings, the second cable constraint 113 is located at the pitch axis motor 20. However, in other embodiments, the second cable constraint 113 may also be located on the inner wall of the cylindrical housing 11 near the edge of the first motor connection position 110.

[0017] Admittedly, by using the method shown in the attached figure to set the second cable constraint 113, the second cable constraint 113 can be first set at the end face of the pitch axis motor 20, and then the pitch axis motor 20 can be installed at the first motor connection position 110, thereby realizing the setting of the second cable constraint 113. Compared with other setting methods, it is easier to set the second cable constraint 113.

[0018] Preferably, the first cable restraint member 112 and the second cable restraint member 113 are located in the same generatrix direction on the inner sidewall of the cylindrical housing 11. In this way, the coaxial line segment between the first and second cable restraint members 112 and 113 is attached to the inner sidewall of the cylindrical housing 11 along the generatrix, which can ensure that this coaxial line segment is tightly attached to the inner sidewall of the cylindrical housing 11.

[0019] like Figure 2 As shown, in this preferred embodiment, the first cable restraint member 112 is designed as an arc-shaped hook extending inward from the inner sidewall of the cylindrical housing 11, so that the coaxial cable can be inserted into the hook and restrained and fixed by the first cable restraint member 112.

[0020] Combination Figure 3 and Figure 4 As shown, in this preferred embodiment, the second cable constraint member 113 is designed as an inverted U-shaped structure, including a top plate 1130, two side plates 1131 extending downward from the two ends of the top plate 1130, and two support plates 1132 extending outward from the lower edge of the side plates 1131. The two support plates 1132 are attached to the target position (for example, on the end face of the pitch axis motor 20 facing the inside of the cylindrical housing 11, or on the inner wall of the cylindrical housing 11 near the edge of the first motor connection position 110), and can be fastened with screws to realize the installation of the second cable constraint member 113. In this way, a coaxial cable can be passed through the second cable constraint member 113 and constrained and fixed by the second cable constraint member 113.

[0021] See Figure 1 and Figure 2In this preferred embodiment, the first motor connection position 110 includes a connection position opening 1100 formed on the side wall of the cylindrical housing 11, a connection position enclosure 1101 extending outward around the connection position opening 1100, and an annular connecting plate 1102 disposed at the inner end face of the connection position enclosure 1101. The rotor of the pitch axis motor 30 is connected to the annular connecting plate 1102 to drive the lens housing 10 to rotate, thereby realizing the pitch operation of the lens module 40 installed inside the lens housing.

[0022] See Figure 1 and Figure 2 In this preferred embodiment, the first motor mounting position 111 includes a plurality of mounting support plates 1110 spaced apart around the rear inner wall of the cylindrical housing 11, each mounting support plate 1110 having a screw hole 1111. Thus, the motor mounting plate 31 fixed to the roll motor 30 is supported by the plurality of mounting support plates 1110, and screws are passed through the motor mounting plate 31 and screwed onto the mounting support plates 1110, thereby enabling the roll motor 30 to be mounted inside the cylindrical housing 11.

[0023] See Figure 1 This utility model also discloses a gimbal, which includes a support arm mechanism, a pitch axis motor 20, a roll axis motor 30, and a gimbal control board. The support arm mechanism includes a base, a pitch axis motor mount connected to the base via a cantilever, and a lens housing 10 with the structure described in the above embodiments. The pitch axis motor 20 is installed in the pitch axis motor mount, and its rotor is connected to the lens housing 10 so that the lens housing 10 can rotate under the drive of the pitch axis motor 20. The roll axis motor 30 is installed inside the cylindrical housing 11 of the lens housing 10, and its rotor is connected to the lens module 40 installed inside the cylindrical housing 11 so that the lens module 40 can rotate under the drive of the roll axis motor 30. The coaxial cable extends from the image sensor board 41 of the lens module 40, passes through the roll axis motor 30, is constrained and positioned by the first cable constraint member 112, then attaches to the inner wall of the cylindrical housing 11, extends to the second cable constraint member 113, is constrained and positioned by the second cable constraint member 113, and is then introduced into the pitch axis motor 20.

[0024] In some embodiments, the gimbal also includes a yaw axis motor, the rotor of which is connected to the base of the support arm mechanism, thereby driving the support arm mechanism to rotate and thus realizing the yaw operation of the lens module 40.

[0025] When the gimbal is not equipped with a yaw axis motor, it is a two-axis gimbal; when the gimbal is equipped with a yaw axis motor, it is a three-axis gimbal.

[0026] Other aspects of the gimbal, such as the routing of the coaxial cable after passing through the pitch axis motor 20, and the control of the yaw axis motor by the gimbal control board, can be addressed using existing technologies and will not be elaborated upon here.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Those skilled in the art can make various equivalent changes and improvements based on the above embodiments. All equivalent changes or modifications made within the scope of the claims should fall within the protection scope of the present utility model.
