Description

Technical Field

[0001] This invention relates to the field of rotating structure design technology, and more particularly to a rotating component and electronic device. Background Technology

[0002] Currently, motors are designed with gear transmission structures to achieve the rotation of the output shaft. When multiple gears are fully meshed, the transmission resistance increases, power loss increases, and gears are prone to wear. When the gear teeth wear to a certain extent, the transmission between multiple gears will be smoother. In addition, excessively tight gear clearance will cause power loss and consume more electricity, while excessively large gear clearance can easily cause tooth shaving problems. Therefore, the tooth clearance between multiple gears in a motor should not be too large or too small. Normal gears will have an appropriate clearance.

[0003] When motors are used in electronic devices that require rotation, such as monitoring equipment, the gear backlash of the motor can cause the rotating parts and the monitoring camera on the rotating parts to wobble due to gravity when they are tilted and rotated, which seriously affects the stability of the monitoring camera's rotation.

[0004] Therefore, finding a technical solution that can solve the above-mentioned technical problems has become an important research topic for those skilled in the art. Summary of the Invention

Detailed Implementation

[0028] This invention discloses a rotating component and an electronic device, which solves the technical problem that the rotating component is prone to shaking during the rotation process driven by the motor in existing rotating components.

[0029] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 6 The present invention provides a rotating assembly, including a motor 1, an elastic element 3, and a rotating element 2 for assembling electronic devices;

[0031] The output shaft of the motor 1 is connected to the rotating member 2 to drive the rotating member 2 to rotate around the output shaft of the motor 1. The housing of the motor 1 is connected to the rotating member 2 through the elastic member 3. The elastic member 3 is used to provide a pulling force to the rotating member 2 when the rotating member 2 rotates, and the pulling force is greater than the weight of the rotating member 2 and the electronic device.

[0032] It should be noted that the tension provided by the elastic element 3 to the rotating element 2 in this embodiment needs to be less than the driving force of the motor 1 drive shaft, so as to avoid the motor 1 being unable to drive the rotating element 2 to rotate due to the excessive tension of the elastic element 3.

[0033] Furthermore, it should be noted that in order to enable the elastic element 3 to provide tension to the rotating part 2 when the rotating part 2 rotates, the elastic element 3 has already undergone a certain elastic deformation after assembly. It can be simply understood that the elastic element 3 has already provided tension to the rotating part 2 after assembly.

[0034] In the rotating assembly of this embodiment, the motor 1 and the rotating component 2 are connected by an elastic element 3, and the drive shaft of the motor 1 is connected to the rotating component 2 to drive the rotating component 2 to rotate. Through this design, when the motor 1 drives the rotating component 2 to rotate, the elastic element 3 always applies a pulling force to the rotating component 2, and the pulling force of the elastic element 3 is greater than the weight of the rotating component 2 and the electronic device mounted on the rotating component 2. This overcomes the problem of wobbling during the rotation of the rotating component 2 and effectively improves the stability of the rotating component 2 during rotation.

[0035] Furthermore, in this embodiment, the rotating component 2 is provided with a positioning groove 201, the elastic component 3 is installed in the positioning groove 201, and the first end 301 of the elastic component 3 is fixedly connected to the rotating component 2, and the second end 302 of the elastic component 3 is fixedly connected to the housing of the motor 1.

[0036] It should be noted that the positioning groove 201 in this embodiment is specifically set on the side of the rotating part 2 facing the motor 1, and the positioning groove 201 is specifically an annular groove structure. Through the above design, the stability of the elastic part 3 installation can be ensured, and the elastic part 3 can be prevented from falling off during the rotation of the rotating part 2.

[0037] Furthermore, in this embodiment, the rotating member 2 is provided with a slot 203, the slot 203 is connected to the positioning slot 201, and the first end 301 of the elastic member 3 is inserted into the slot 203.

[0038] It should be noted that the above design allows operators to easily fix the first end 301 of the elastic element 3 to the rotating element 2. Alternatively, in other embodiments, the first end 301 of the elastic element 3 can be fixedly connected to the rotating element 2 by locking with a fixing screw.

[0039] This embodiment does not restrict the fixed connection method between the first end 301 of the elastic member 3 and the rotating member 2. Designers can choose a suitable fixed connection method according to actual needs.

[0040] Furthermore, in this embodiment, a movable groove 202 is also provided on the outer wall of the positioning groove 201, and the second end 302 of the elastic member 3 is movably disposed in the movable groove 202 and fixedly connected to the housing of the motor 1.

[0041] It should be noted that since the second end 302 of the elastic element 3 is fixedly connected to the housing of the motor 1, when the rotating element 2 is driven to rotate, the second end 302 of the elastic element 3 will rotate relative to the rotating element 2. Therefore, through the design of the above-mentioned movable groove 202, interference between the second end 302 of the elastic element 3 and the rotating element 2 can be avoided, which would cause the rotating element 2 to rotate unevenly.

[0042] Specifically, in this embodiment, the movable groove 202 is an arc-shaped groove with the same movement trajectory as the second end 302 of the elastic member 3.

[0043] Furthermore, in this embodiment, a fixing plate 101 is provided on the housing of the motor 1, and a locking hole 102 is provided on the fixing plate 101, and the second end 302 of the elastic member 3 is inserted into the locking hole 102.

[0044] It should be noted that the above design allows operators to easily fix the second end 302 of the elastic element 3 to the housing of the motor 1. Alternatively, in other embodiments, the second end 302 of the elastic element 3 can also be fixedly connected to the housing of the motor 1 by locking with screws.

[0045] Furthermore, in this embodiment, the fixing member has a first surface facing the rotating member 2 and a second surface facing away from the rotating member 2, and the second end 302 of the elastic member 3 wraps around from the first surface to the second surface and then gets into the locking hole 102.

[0046] It should be noted that the above design makes the second end 302 of the elastic element 3 more securely connected to the housing of the motor 1, and prevents the second end 302 of the elastic element 3 from falling off during the rotation of the rotating part 2.

[0047] Furthermore, in this embodiment, the elastic element 3 is a torsion spring.

[0048] It should be noted that in this embodiment, the torsion spring has a first end 301, a second end 302, and a winding portion connecting the first end 301 and the second end 302, wherein the winding portion is specifically placed in the positioning groove 201.

[0049] In other specific embodiments, the elastic element 3 may also be a spring sheet with a specific structure, and this embodiment does not limit this.

[0050] Please see Figure 1 An electronic device provided in this embodiment of the invention includes an electronic device and a rotating component;

[0051] The electronic device is mounted on the rotating component 2 of the rotating assembly.

[0052] Specifically, in this embodiment, the electronic device is a monitoring device, and the electronic device is a monitoring camera. The monitoring camera is mounted on the rotating member 2. Therefore, the tension provided by the elastic member 3 in this embodiment needs to be greater than the weight of the rotating member 2 and the monitoring camera.

[0053] With the above design, when the motor 1 drives the rotating part 2 to rotate, the elastic element 3 always applies a pulling force to the rotating part 2, and the pulling force of the elastic element 3 is greater than the weight of the rotating part 2 and the monitoring camera mounted on the rotating part 2. This can overcome the problem of the rotating part 2 shaking during rotation and effectively improve the stability of the rotating part 2 during rotation.

[0054] The above describes the specific structure of a rotating component and electronic device provided by the present invention. The rotating component of the present invention will be further described below using a specific application process. The specific application process of the rotating component in this embodiment is as follows:

[0055] Taking monitoring equipment as an example, the rotating part 2 of the rotating assembly is equipped with a monitoring camera;

[0056] Please see Figure 6 When the rotating component 2 is driven to rotate counterclockwise to the maximum angle, the rotating component 2 and the monitoring camera are in an upward-facing position. At this time, the tension applied by the elastic component 3 is minimal.

[0057] When the rotating component 2 drives the rotating component 2 and the monitoring camera to rotate from the tilted-up position to the vertical position, the elastic component 3 has a certain tension.

[0058] When the rotating component 2 drives the rotating component 2 and the monitoring camera to rotate clockwise to the maximum angle, the rotating component 2 and the monitoring camera are in a downward position, and at this time the tension applied by the elastic component 3 is the maximum.

[0059] During the above rotation process, the elastic element 3 always provides tension to the rotating element 2 and the monitoring camera to ensure that the rotating element 2 does not wobble during the rotation process, thus ensuring the stability of the rotating element 2 during rotation.

[0060] The rotating component and electronic device provided by the present invention have been described in detail above. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the embodiments of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
