Description

Technical Field

[0001] This utility model relates to the field of telescopic structure technology, and in particular to a step-telescopic locking mechanism. Background Technology

[0002] Telescopic locking mechanisms are mechanical devices used to adjust height or length. They are widely used in various scenarios that require spatial adjustment, position changes, or form switching, such as electronic products with cameras.

[0003] Currently, most telescopic locking mechanisms in existing technologies use a compression spring transmission mechanism for opening and closing. The compression and rebound of the spring achieve the telescopic opening and closing. However, this transmission mechanism results in poor stability of the telescopic module during extension and retraction, and the control precision of the telescopic module is not ideal. At the same time, most telescopic locking mechanisms on the market are manually adjustable and not intelligent enough, thus having certain defects. Therefore, they cannot meet the ultimate pursuit of user experience for different user groups. Utility Model Content

[0004] The purpose of this invention is to provide a step-by-step telescopic locking mechanism that has good telescopic stability, high telescopic accuracy, and can be remotely controlled.

[0005] To solve the above technical problems, the present invention can be implemented using the following technical solutions: A step-telescopic locking mechanism includes a main housing, a telescopic shell, a PCBA assembly, a camera module, a driver, and a telescopic bracket. One end of the main housing has an opening. The camera module is mounted on one end of the telescopic shell. The PCBA assembly and the driver are respectively disposed inside the telescopic shell, and the camera module and the driver are electrically connected to the PCBA assembly. One end of the telescopic bracket is placed inside the telescopic shell and is connected to the driver, while the other end extends from the opening and connects to the main housing. The driver can drive the telescopic bracket to move, causing the end of the telescopic shell away from the camera module to extend outward or retract inward from the opening of the main housing.

[0006] In one embodiment, a guide rod is provided inside the telescopic housing, and the telescopic bracket has a fork-shaped arm and a connecting arm. The fork-shaped arm of the telescopic bracket is placed inside the telescopic housing and sleeved on the guide rod, and can move along the guide rod.

[0007] In one embodiment, the telescopic bracket is provided with a rack on its fork-shaped arm, and a gear is provided at the output end of the drive unit. The gear meshes with the rack, and the drive unit drives the telescopic bracket to move along the guide rod through the gear and rack.

[0008] In one embodiment, the telescopic bracket has a connector at the end of its connecting arm and a connecting post inside the main housing. The connecting arm engages with the connecting post through the connector to connect the telescopic bracket to the main housing.

[0009] In one embodiment, the PCBA assembly is provided with two sets of inductive switches and two sets of pressing blocks are provided on the telescopic bracket. The two sets of pressing blocks cooperate with the two sets of inductive switches respectively, and correspond one-to-one.

[0010] In one embodiment, the telescopic housing has limit grooves on both sides at the end away from the camera module, and limit blocks are provided on both sides inside the main housing, with the limit blocks placed in the limit grooves.

[0011] In one embodiment, the end of the telescopic housing is provided with a fixing groove, and fixing holes are provided on both sides of the fixing groove.

The second buckle is snapped into the second slot so that the telescopic top cover and the telescopic bottom shell cover each other.

[0014] In one embodiment, the driving element is a stepper motor. Beneficial effects

[0015] This utility model relates to a stepper telescopic locking mechanism. A camera module is mounted at one end of a telescopic housing, while the other end of the housing is connected to the main housing via a telescopic bracket. The telescopic housing contains a driving component, a stepper motor, with a gear at its output end. The telescopic bracket also has a rack that meshes with the gear. The interaction of the driving component, gear, and rack drives the telescopic bracket to move, thereby extending and retracting the telescopic housing relative to the main housing to change the position of the camera module. The use of a stepper motor, gear, and rack ensures the stability and precision of the telescopic housing during extension and retraction. Furthermore, in conjunction with a PCBA assembly, remote control operation is possible, eliminating the need for manual adjustment and enhancing intelligence.

[0021] Please see Figures 1 to 8 A step-and-retractable locking mechanism includes a main housing 100, a telescopic shell 200, a PCBA assembly 300, a camera module 400, a drive component 500, and a telescopic bracket 600. One end of the main housing 100 has an opening. The camera module 400 is mounted on one end of the telescopic shell 200. The PCBA assembly 300 and the drive component 500 are respectively disposed inside the telescopic shell 200 and electrically connected to the PCBA assembly. One end of the telescopic bracket 600 is located inside the telescopic shell 200 and is connected to the drive component 500, while the other end extends from the opening and connects to the main housing 100. The drive component 500 can drive the telescopic bracket 600 to move, causing the end of the telescopic shell 200 away from the camera module 400 to extend outward or retract inward from the opening of the main housing 100.

[0022] Specifically, in this embodiment, the camera module 400 is installed at one end of the telescopic housing 200, and the other end of the telescopic housing 200 is connected to the main housing 100 via the telescopic bracket 600. The PCBA assembly 300 and the drive unit 500 are respectively disposed within the telescopic housing 200. The drive unit 500 is a stepper motor, and a gear 510 is provided at the output end of the drive unit 500. The telescopic bracket 600 is provided with a rack 630 that meshes with the gear 510. The drive unit 500 can drive the gear 510 to rotate. Since the rack 630 meshes with the gear 510, when the gear 510 rotates, the telescopic bracket 600 moves through the rack 630. The telescopic housing 200 will move, causing it to extend outward or retract inward relative to the opening of the main housing 100, thereby changing and adjusting the position of the camera module 400. The use of a stepper motor, gear 510, and rack 630 as the drive method makes the telescopic bracket 600 more stable during extension and retraction, thus ensuring the stability and accuracy of the extension and retraction of the telescopic housing 200. In addition, with the software algorithm built into the PCBA component 300, the drive component 500 can be automatically controlled to realize remote operation to adjust the position of the camera module 400 without manual operation, thereby improving the level of intelligence and ensuring high-precision and controllable distance adjustment of the telescopic range.

[0023] To precisely control the extension and retraction locking states of the telescopic housing 200, in this embodiment, two sets of inductive switches 310 are provided on the PCBA assembly 300, and two sets of pressing blocks 650 are provided on the telescopic bracket 600. The two sets of pressing blocks 650 respectively cooperate with the two sets of inductive switches 310, and correspond one-to-one. The two sets of inductive switches 310 and the two sets of pressing blocks 650 are arranged at a distance from each other. When the telescopic housing 200 extends outward to a set position, the front pressing block 650 will act on the front inductive switch 310 to promptly sense and precisely control the extension position of the telescopic housing 200. Similarly, when the telescopic housing 200 retracts inward to a set position, the rear pressing block 650 will act on the rear inductive switch 310 to also promptly sense and precisely control the retraction locking position of the telescopic housing 200, thereby ensuring high-precision control and adjustment of the extension and retraction locking of the telescopic housing 200.

[0024] Furthermore, to ensure the limiting of the telescopic housing 200 and the main housing 100, in this embodiment, limiting grooves 220 are provided on both sides of the end of the telescopic housing 200 away from the camera module 400, and limiting blocks 120 are provided on both sides inside the main housing 100. When the telescopic housing 200 and the main housing 100 are assembled, the limiting blocks 120 will be placed in the limiting grooves 220 to achieve the limiting connection between the telescopic housing 200 and the main housing 100, and the telescopic range of the telescopic housing 200 is controlled by the cooperation of the limiting grooves 220 and the limiting blocks 120.

[0025] Please see Figure 3 , Figure 5 and Figure 6 In order to achieve the telescopic extension and retraction of the telescopic housing 200, in this embodiment, a guide rod 210 is provided inside the telescopic housing 200, and the telescopic bracket 600 has a fork-shaped arm 610 and a connecting arm 620. The fork-shaped arm 610 of the telescopic bracket 600 is placed inside the telescopic housing 200 and sleeved on the guide rod 210, and can move along the guide rod 210. One end of the connecting arm 620 is connected to the fork-shaped arm 610, and the other end is connected to the main housing 100. At the same time, a rack 630 is provided on the fork-shaped arm of the telescopic bracket 600, and a gear 510 is provided at the output end of the drive member 500. The gear 510 and the rack 630 mesh with each other. The drive member 500 drives the telescopic bracket 600 to move along the guide rod 210 through the gear 510 and the rack 630.

[0026] Two guide rods 210 are provided inside the telescopic housing 200, and the fork-shaped arm 610 of the telescopic bracket 600 is placed inside the telescopic housing 200 and sleeved on the guide rods 210. The guide rods 210 can maintain the balance of the fork-shaped arm 610, thereby making the telescopic bracket 600 more stable when moving, thus ensuring the stability of the telescopic housing 200 during extension and retraction. At the same time, a rack 630 is provided at the bottom of the fork-shaped arm 610. The rack 630 meshes with the gear 510 at the output end of the drive unit 500. When the drive unit 500 drives the gear 510 to rotate, the gear 510 will act on the rack 630, so that the telescopic bracket 600 moves along the guide rods 210, thereby realizing the extension and retraction of the telescopic housing 200 and controlling and adjusting the position of the camera module 400 on the telescopic housing 200.

[0027] Please see Figure 6 and Figure 7To connect the telescopic bracket 600 to the main housing 100, a connector 640 is provided at the end of the connecting arm 620 of the telescopic bracket 600, and a connecting post 110 is provided inside the main housing 100. The end of the connecting arm 620 is inserted into the opening of the main housing 100, so that the connector 640 at its end corresponds with the connecting post 110 inside the main housing 100. Then, the connector 640 and the connecting post 110 are locked together with screws, thereby realizing the connection between the telescopic bracket 600 and the main housing 100, and making its connection structure design reasonable.

[0028] For further details, please refer to Figure 4 A fixing groove 230 is provided at the end of the telescopic housing 200, and fixing holes 231 are provided on both sides of the fixing groove 230. Fixing posts 410 are provided on both sides of the camera module 400. When assembling the camera module 400, the fixing posts 410 on both sides of the camera module 400 are respectively inserted into the fixing holes 231 on both sides of the fixing groove 230, so that the camera module 400 can be installed in the fixing groove 230, thereby realizing the assembly of the camera module 400 and making the assembly convenient and simple.

[0029] Please see Figure 7 and Figure 8 To facilitate the assembly of the telescopic locking mechanism, the main box body 100 in this embodiment includes a bottom cover 130 and a top cover 140. A first slot 131 is provided on the side of the bottom cover 130, and a first buckle 141 is provided on the side of the top cover 140. The first buckle 141 is fastened into the first slot 131 so that the top cover 140 and the bottom cover 130 cover each other. The telescopic housing 200 includes a telescopic bottom shell 240 and a telescopic top cover 250. A second buckle 241 is provided on the side of the telescopic bottom shell 240, and a second slot 251 is provided on the side of the telescopic top cover 250. The second buckle 241 is fastened into the second slot 250 so that the telescopic top cover 250 covers each other.

[0030] By fastening the first buckle 141 into the first slot 131, the front cover 140 and the bottom cover 130 can be fitted together to form the main box body 100. At the same time, by fastening the second buckle 241 into the second slot 251, the telescopic cover 250 and the telescopic bottom shell 240 can be fitted together to form the telescopic shell 200. When assembling the telescopic locking mechanism, the PCBA assembly 300 and the drive component 500 are first installed in the telescopic bottom shell 240, and the camera module 400 is installed at the end of the telescopic bottom shell 240. Then, the guide rod 210 and the fork arm 610 of the lifting bracket 600 are installed. Then, the lifting cover 250 is fitted with the lifting bottom shell 240. Finally, the front cover 140, the bottom cover 130 and the connector 640 of the connecting arm 620 are installed respectively, thereby completing the assembly of the telescopic locking mechanism.
