Description
Technical Field
[0001] This utility model relates to the field of cameras, specifically to a rotating mechanism and a device with a rotating function. Background Technology
[0002] The camera device achieves horizontal rotation through a rotating mechanism. Existing rotating mechanisms typically fix the bearing and then clamp the inner ring of the bearing with two structural components to achieve both fixation and rotation. In addition, the rotating mechanism also uses a gear ring and gears to achieve electric rotation. The existing rotating mechanism has a relatively complex structure and assembly. Utility Model Content
[0003] To address the aforementioned problems and overcome at least one deficiency, this utility model proposes a rotating mechanism and a device with a rotating function.
[0004] The technical solution adopted by this utility model is as follows:
[0005] A rotating mechanism, comprising:
[0006] Rotating bracket with a protrusion;
[0007] A bearing having an inner ring and an outer ring, wherein the inner ring of the bearing is fitted over the protrusion and is tightly fitted to the protrusion;
[0008] The first fastener is fixed on the rotating bracket and is used to retain the inner ring of the bearing to prevent the bearing from detaching from the protrusion.
[0009] The motor bracket has a mounting groove, and the outer ring of the bearing is fitted into the mounting groove and tightly fitted therewith.
[0010] A drive motor is fixed on the motor bracket, and the output shaft of the drive motor is connected to the rotating bracket.
[0011] The second fastener is fixed to the motor bracket and is used to restrain the outer ring of the bearing to prevent the bearing from coming out of the mounting groove.
[0012] The rotating mechanism of this application directly defines the inner ring through a first fastener fixed to the rotating bracket and the outer ring through a second fastener fixed to the motor bracket, effectively combining the rotating bracket, bearing, and motor bracket together. The entire structure is simple and reliable. The output shaft of the drive motor is directly connected to the rotating bracket. When the rotating bracket is stationary, the drive motor can drive the motor bracket to rotate relative to the rotating bracket after it is working. Compared with the gear and ring gear structure, the transmission structure is simple.
[0013] This application has a relatively simple structure and assembly. It can increase the reliability of the structure and the yield rate of production.
[0014] In this application, tight fit refers to interference fit or transition fit.
[0015] In practical applications, the first and second fasteners can be screws with washers or washer screws.
[0016] In one embodiment of the present invention, the protrusion has a first threaded hole, and the first fastener is connected to the first threaded hole;
[0017] The motor bracket has a second threaded hole on the outside of the mounting slot, and the second fastener is connected to the second threaded hole.
[0018] In one embodiment of the present invention, the first fastener is a spacer screw, and the second fastener is a spacer screw;

[0020] The washer portion of the washer screw increases the contact area with the corresponding part of the bearing, which can reliably constrain the bearing. Compared with a separate washer design, the assembly is simpler and more efficient, and it is less likely to miss the washer.
[0021] In one embodiment of the present invention, the rotating bracket has a through hole, and the second fastener passes through the through hole and connects to the second threaded hole of the motor bracket.

[0026] The entire assembly process is simple, reliable, and yields a high success rate.
[0027] In one embodiment of the present invention, the rotating bracket has a first pipeline channel, and the motor bracket has a second pipeline channel.
[0028] The conduit channels are used for the passage of wiring. In practical applications, some or all of the circuit boards can be mounted on a rotating bracket. The circuit boards are connected to other components, such as drive motors, through wires passing through the first and second conduit channels.
[0029] In one embodiment of the present invention, the protrusion has a socket, the output shaft of the drive motor is inserted into the socket, and the output shaft and the socket are fixed relative to each other in the circumferential direction.
[0030] The output shaft and the socket are relatively fixed in the circumferential direction, meaning that the output shaft rotates synchronously with the convex part. In practical applications, this can be achieved by using a structure with a non-circular cross-section, such as a non-circular cross-section of the socket, where the outer contour of the end cross-section of the output shaft matches the inner contour of the socket cross-section.
[0031] In one embodiment of the present invention, the drive motor is fixed to the motor bracket by a third fastener.
[0032] In practical applications, the third fastener is preferably a spacer screw.
[0033] In practical applications, the drive motor can have perforated lugs, and the third fastener passes through the perforated lugs and is fixed to the motor bracket.
[0034] This application also discloses a device with a rotation function, including a base, a housing, and a rotation mechanism. The rotation mechanism is the one described above. The base is fixed below the rotation bracket, and the housing is fixed on the motor bracket.
[0035] The base is placed on the support surface, and the drive motor works, causing the motor bracket and the outer shell to rotate relative to the rotating bracket fixed to the base.
[0036] In one embodiment of the present invention, the outer shell includes a front shell and a rear shell connected to each other, the rotating bracket has a clearance hole, the front shell is fixed to the motor bracket by a connector passing through the clearance hole, and the rear shell is fixed to the motor bracket by a connector passing through the clearance hole.

[0038] Fix the drive motor to the motor bracket;
[0039] The bearing is fitted onto the protrusion of the rotating bracket, and the inner ring of the bearing is defined by the first fastener;
[0040] The rotating bracket is assembled onto the motor bracket, the outer circle of the bearing is fitted into the mounting groove of the motor bracket, and then the inner ring of the bearing is defined by a second fastener passing through the through hole.
[0041] The front and rear housings are fastened onto the rotating mechanism, and then the motor bracket is fixed to the housing by a connector passing through the clearance hole;
[0042] Secure the base to the rotating bracket.
[0043] In practical use, the bottom of the base also has anti-slip pads.
[0044] In practical applications, the connecting parts are commonly used fasteners such as bolts or screws.
[0045] In one embodiment of the present invention, a camera mounted on the housing is also included.
[0046] The beneficial effects of this utility model are as follows: The rotating mechanism of this application directly defines the inner ring through the first fastener fixed to the rotating bracket and the outer ring through the second fastener fixed to the motor bracket, effectively combining the rotating bracket, bearing, and motor bracket together. The entire structure is simple and reliable. The output shaft of the drive motor is directly connected to the rotating bracket. When the rotating bracket is fixed, the motor can drive the motor bracket to rotate relative to the rotating bracket after it is working. Compared with the gear and ring gear structure, the transmission structure is simple. Attached Figure Description

[0061] The present invention will now be described in detail with reference to the accompanying drawings.
[0062] like Figures 1-5 As shown, a rotating mechanism 1 includes:
[0063] The rotating bracket 11 has a protrusion 111;
[0064] The bearing 12 has an inner ring 121 and an outer ring 122, with the inner ring 121 of the bearing 12 being sleeved on and tightly fitted to the protrusion 111;
[0065] The first fastener 13 is fixed on the rotating bracket 11 and is used to limit the inner ring 121 of the bearing 12 to prevent the bearing 12 from dislodging from the protrusion 111.
[0066] The motor bracket 14 has a mounting groove 141, and the outer ring 122 of the bearing 12 is fitted into the mounting groove 141 and is tightly fitted with the mounting groove 141.
[0067] The drive motor 15 is fixed on the motor bracket 14, and the output shaft 151 of the drive motor 15 is connected to the rotating bracket 11;
[0068] The second fastener 16 is fixed on the motor bracket 14 and is used to limit the outer ring 122 of the bearing 12 to prevent the bearing 12 from falling out of the mounting groove 141.
[0069] The rotating mechanism 1 of this application directly defines the inner ring 121 by a first fastener 13 fixed to the rotating bracket 11, and defines the outer ring 122 by a second fastener 16 fixed to the motor bracket 14, effectively combining the rotating bracket 11, bearing 12, and motor bracket 14. The entire structure is simple and reliable. The output shaft 151 of the drive motor 15 is directly connected to the rotating bracket 11. When the rotating bracket 11 is fixed, the drive motor 15 can drive the motor bracket 14 to rotate relative to the rotating bracket 11 after it is working. Compared with the gear ring structure, the transmission structure is simple.
[0070] This application has a relatively simple structure and assembly. It can increase the reliability of the structure and the yield rate of production.
[0071] In this application, tight fit refers to interference fit or transition fit.
[0072] In practical applications, the first fastener 13 and the second fastener 16 can be screws with washers or washers.
[0073] like Figure 3 and 4 As shown, in this embodiment, the protrusion 111 has a first threaded hole 1111, and the first fastener 13 is connected to the first threaded hole 1111.
[0074] like Figure 5 As shown, the motor bracket 14 has a second threaded hole 142 on the outside of the mounting groove 141, and the second fastener 16 is connected to the second threaded hole 142.
[0075] like Figure 2 and 3 As shown, in this embodiment, the first fastener 13 is a spacer screw, and the second fastener 16 is a spacer screw.
[0076] The medium screw has a washer portion 131. The washer portion 131 of the first fastener 13 contacts and engages with the end face of the inner ring 121 of the bearing 12, and the washer portion 131 of the second fastener 16 contacts and engages with the end face of the outer ring 122 of the bearing 12.
[0077] The washer portion 131 of the washer screw can increase the contact area with the corresponding part of the bearing 12, and can reliably limit the bearing 12. Compared with a separate washer design, the assembly is simpler and more efficient, and it is less likely to miss the washer.

For example, the cross-section of the socket 1112 is not circular, and the outer contour of the end cross-section of the output shaft 151 matches the inner contour of the cross-section of the socket 1112.

[0093] like Figure 5 and 7 As shown, in this embodiment, the outer shell 2 includes a front shell 21 and a rear shell 22 connected to each other. The rotating bracket 11 has a clearance hole 114. The front shell 21 is fixed to the motor bracket 14 by a connector 5 passing through the clearance hole 114, and the rear shell 22 is fixed to the motor bracket 14 by a connector 5 passing through the clearance hole 114.

[0096] The bearing 12 is fitted onto the protrusion 111 of the rotating bracket 11, and the inner ring 121 of the bearing 12 is defined by the first fastener 13;
[0097] The rotating bracket 11 is assembled onto the motor bracket 14, the outer circle of the bearing 12 is fitted into the mounting groove 141 of the motor bracket 14, and then the inner ring 121 of the bearing 12 is defined by a second fastener 16 passing through the through hole 112.
