[0001] The utility model relates to a holder camera technical field, concretely relates to a lens shell and holder. BACKGROUND

[0002] In the common holder camera, the support arm mechanism of holder includes a base, a pitch shaft motor seat for installing pitch shaft motor (Pitch shaft motor) through a cantilever connected with the base and a lens shell driven by the pitch shaft motor, which is used for installing roll shaft motor (Roll shaft motor) and lens module driven by the roll shaft motor. When wiring, the coaxial line is led out from the image sensor circuit board of the lens module, passes through the rotating shaft of the roll shaft motor, and then reaches the pitch shaft motor along the inner wall of the lens shell, and finally passes through the pitch shaft motor and is led out from the lens shell. In this way, when the roll shaft motor works and drives the lens module to rotate, the coaxial line between the roll shaft motor and the pitch shaft motor will swing inside the lens shell due to the influence of torsion, thereby affecting the normal rotation of the lens module and causing instability of the product. SUMMARY

[0003] The technical problem to be solved by the utility model lies in providing a lens shell and holder which can effectively limit the internal coaxial line.

[0004] To solve the above technical problem, according to one aspect of the utility model, a lens shell is provided, which comprises:

[0005] A shell;

[0006] A first motor connecting position for connecting the pitch shaft motor is formed in the middle of the side wall of the shell;

[0008] A cable constraint cavity is formed between the inner side wall of the shell and the outer side wall of the stator of the roll shaft motor, and is used for accommodating the coaxial line.

[0009] Further technical solutions are as follows: the inner side wall of the shell and the outer side wall of the stator of the roll shaft motor form the cable constraint cavity along the direction from the inner rear end of the shell to the first motor connecting position.

[0010] Further technical solutions are as follows: the first motor connecting position comprises a connecting position opening formed on the side wall of the shell, a connecting position enclosure extending outward around the connecting position opening, and an annular connecting plate arranged at the inner end face of the connecting position enclosure.

[0011] Further, the first motor mounting position comprises a mounting bearing plate located inside the rear end of the shell body, a through hole is formed in the mounting bearing plate, and screw holes or through holes are formed around the mounting bearing plate.

[0012] Further, the lens shell further comprises a sealing cover, the sealing cover is arranged at the rear end of the shell body and located outside the mounting bearing plate.

[0013] To solve the above technical problems, according to another aspect of the present application, a gimbal is provided, comprising:

[0014] A support arm mechanism comprises a base, a pitch shaft motor seat connected to the base through a cantilever, and the above-mentioned lens shell;

[0015] A pitch shaft motor is installed in the pitch shaft motor seat, and the rotor of the pitch shaft motor is connected to the lens shell;

[0016] A roll shaft motor is installed in the shell body of the lens shell, and the rotor of the roll shaft motor is connected to a lens module installed inside the shell body;

[0017] A coaxial cable is led out from an image sensor board of the lens module, passes through the roll shaft motor, enters the shell body, and is positioned by the cable constraint cavity.

[0018] Further, the gimbal further comprises a yaw shaft motor, and the rotor of the yaw shaft motor is connected to the base.

[0019] The beneficial technical effects of the present application are as follows: compared with the prior art, when the lens shell is used, a cable constraint cavity for accommodating a coaxial cable is formed between the inner side wall of the shell body and the outer side wall of the roll shaft motor stator located inside the rear end of the shell body. Since the roll shaft motor stator and the inner wall of the shell body are relatively stationary, the cable constraint cavity can limit the coaxial cable. By arranging the cable constraint cavity, the coaxial cable can be positioned by the cable constraint cavity after passing through the roll shaft motor and entering the shell body, and then introduced into the pitch shaft motor. Thus, the coaxial cable between the roll shaft motor and the pitch shaft motor can be effectively limited. When the roll shaft motor rotates, interference to the internal components of the shell body can be prevented, adverse effects on the normal operation of the lens module can be avoided, and the working stability of the gimbal camera can be ensured.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] The lens shell disclosed by the utility model can be used as part of the support arm structure of a two-axis or three-axis gimbal, for installing lens modules of a gimbal camera, horizontal roll axis motors of a two-axis or three-axis gimbal, and other components. The lens shell is connected to a tilt axis motor of a two-axis or three-axis gimbal and is driven by the tilt axis motor, thereby driving the lens module to rotate, to realize tilt operation of the lens module. The lens module is connected to a horizontal roll axis motor and is driven by the horizontal roll axis motor, to realize horizontal roll operation of the lens module.

[0028] Reference is made to Figures 1 to 4 , Figures 1 to 4 ​The utility model discloses a specific embodiment of lens housing 10 is demonstrated. In the embodiment shown in the drawing, the lens housing 10 includes a shell 11, the first motor connecting position 110 for connecting the pitch axis motor 20 is formed in the middle of the side wall of the shell 11, the first motor mounting position 111 for installing the roll axis motor 30 is formed in the inside of the rear end of the shell 11, and the cable constraint cavity 113 for accommodating the coaxial line 40 is formed between the inside wall of the shell 11 and the outside wall of the stator of the roll axis motor 30, specifically, the cable constraint cavity 113 is formed between the inside wall of the shell 11 and the outside wall of the stator of the roll axis motor 30 along the direction from the inside rear end of the shell 11 to the first motor connecting position 110. Thus, by the arrangement of the cable constraint cavity 113, the coaxial line 40 passes through the roll axis motor 30 and then enters the shell 11, and can be positioned by the cable constraint cavity 113, and is introduced into the pitch axis motor 20. Since the stator of the roll axis motor 30 and the inside wall of the shell 11 are relatively stationary, the coaxial line 40 between the roll axis motor 30 and the pitch axis motor 20 can be constrained in the cable constraint cavity 113. When the roll axis motor 30 rotates, the influence of the torsion of the coaxial line 40 can be reduced, the rotor of the roll axis motor 30 and the coaxial line 40 are prevented from colliding to affect the normal rotation of the roll axis motor 30, and the coaxial line 40 is prevented from being pulled to cause the coaxial line 40 to be caught and broken, affecting signal transmission. The influence of the coaxial line 40 on the normal working lens module when the roll axis motor 30 rotates can be eliminated, and the working stability of the gimbal camera is ensured.

[0029] Continuing to refer to Figure 2 And Figure 4 In some embodiments, the first motor connecting position 110 includes a connecting position opening 1100 formed on the side wall of the shell 11, a connecting position enclosure 1101 extending outward around the connecting position opening 1100, and a ring-shaped connecting plate 1102 arranged at the inner end face of the connecting position enclosure 1101. In the embodiment, the rotor of the pitch axis motor 20 is connected with the ring-shaped connecting plate 1102 to drive the rotation of the lens housing 10, so as to realize the pitch operation of the lens module installed inside the lens housing 10.

[0030] In some embodiments, the first motor mounting position 111 comprises a mounting carrier plate 1110 inside the rear end of the shell 11, the mounting carrier plate 1110 is provided with a through hole 1111 and a plurality of screw holes 1112 around the through hole 1111. Thus, the horizontal roll shaft motor 30 is mounted in the shell 11 by screwing the horizontal roll shaft motor 30 through the through hole 1111 and the screw holes 1112 of the mounting carrier plate 1110. After installation, the coaxial cable 40 passes through the rotating shaft of the horizontal roll shaft motor 30 and the through hole 1111, and then enters the cable constraint cavity 113 in the shell 11. It can be understood that in some other embodiments, the screw holes 1112 on the mounting carrier plate 1110 can also be replaced by through holes. The horizontal roll shaft motor 30 can be mounted by screwing through the through holes of the horizontal roll shaft motor 30 and the mounting carrier plate 1110 and cooperating with the nut.

[0031] Further, in some other embodiments, the lens shell 10 can further comprise a sealing cover, which is arranged at the rear end of the shell 11 and outside the mounting carrier plate 1110 to seal the lens shell 10, so that the lens module and the horizontal roll shaft motor 30 can be sealed in the shell 11 when the lens shell 10 is applied to the gimbal.

[0032] Referring to Figure 5 , Figure 5 is a structural schematic view of a specific embodiment of the gimbal. In combination with Figures 1 to 4 In the embodiment shown in the drawings, the gimbal comprises a support arm mechanism 50, a pitch shaft motor 20, a horizontal roll shaft motor 30 and a gimbal control board. The support arm mechanism 50 comprises a base 51, a pitch shaft motor seat 53 connected to the base 51 through a cantilever arm 52 and the lens shell 10 described in the above embodiment. The pitch shaft motor 20 is mounted in the pitch shaft motor seat 53, the rotor of which is connected to the first motor connecting position 110 of the lens shell 10, so that the lens shell 10 can rotate under the drive of the pitch shaft motor 20. The horizontal roll shaft motor 30 is mounted in the shell 11 of the lens shell 10, the rotor of which is connected to the lens module mounted inside the shell 11, so that the lens module can rotate under the drive of the horizontal roll shaft motor 30. The coaxial cable 40 is led out from the image sensor board of the lens module, passes through the rotating shaft of the horizontal roll shaft motor 30, bends into the shell 11 and is constrained and positioned by the cable constraint cavity 113, and then is introduced into the pitch shaft motor 20. The cable constraint cavity 113 effectively constrains the coaxial cable 40 between the outer wall of the horizontal roll shaft motor 30 and the inner wall of the shell 11, ensuring that the coaxial cable 40 in the shell 11 does not interfere with the horizontal roll shaft motor 30 and the lens module when the horizontal roll shaft motor 30 works, improving the stability of the whole machine, and facilitating processing and assembly.

[0033] Specifically, such as Figure 2 and Figure 4 As shown, four mounting ears 31 are formed on the outer peripheral wall of the stator of the roll motor 23 near the mounting support plate 1110. During assembly, the stator of the roll motor 23 can be locked to the inner wall of the mounting support plate 1110 by screwing through the mounting ears 232 and the screw holes 1112 on the mounting support plate 1110 and screwing into the screw holes 1112.

[0034] In one embodiment, the gimbal may further include a yaw axis motor, the rotor of which is connected to the base 51. The base 51 can rotate under the drive of the yaw axis motor, thereby driving the lens to rotate.

[0035] In this embodiment, when the gimbal does not include a yaw axis motor, the gimbal is a two-axis gimbal; when the gimbal includes a yaw axis motor, it is a gimbal.

[0036] Other aspects of the gimbal, such as the routing of the coaxial cable after passing through the pitch axis motor, 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.

[0037] 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.
