Description

TECHNICAL FIELD

[0002] In the prior art, for two structural members that need to be connected in relative rotation, in order to achieve specific adjustment, viewing or operation, such as a car child seat with electric control function, an electronic display or a control panel. In order to achieve communication or power supply, a transmission line needs to be wound around the two structural members. Usually, the wire is passed through the pivot shaft of one structural member and connected to the other structural member. This connection method has the advantages of convenient assembly and low cost. However, there are also obvious disadvantages. If the wire is directly connected, especially when the two structural members can rotate relative to each other, even if a long wire is provided, the user may not be aware of or recognize the rotation angle, which may cause the wire to be wound and pulled, resulting in circuit breakage or damage to the insulation layer and short circuit.

[0003] In order to avoid the above problems, the prior art also uses a scheme of installing a conductive brush and a conductive ring at the pivot shaft position of the two structural members to avoid the problem of wire winding. However, this scheme still has the following defects: 1. High manufacturing cost, which is not conducive to improving the market competitiveness of products using this scheme in terms of price; 2. The conductive brush and the conductive ring are prone to oxidation and wear during long-term use due to environmental problems, which may cause poor contact; 3.

[0035] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0036] As Figures 1-9As shown, the present invention provides a rotatable anti-entanglement mechanism, comprising a stationary component 1 and a rotating component 2 rotatably connected to each other. A rotatable anti-entanglement device is provided between the stationary component 1 and the rotating component 2, allowing the rotating component 2 to rotate relative to the stationary component 1 within a set angle range. By limiting the rotating component to continue rotating relative to the stationary component 1 after reaching a preset angle, the reliable connection of the wires between the stationary component 1 and the rotating component is effectively ensured to prevent breakage or damage due to pulling. This mechanism is also convenient to manufacture and cost-effective.

[0037] The anti-entanglement device includes a rotation protection component 3 disposed on the stationary component 1, and a corresponding anti-rotation limiting structure 4 disposed on the rotating component 2; or the rotating component 2 is provided with a rotation protection component 3, and the stationary component 1 is provided with an anti-rotation limiting structure 4 accordingly. Figures 4-6 As shown, the present invention preferably places the rotation protection component 3 on the stationary component 1, and correspondingly places the anti-rotation limiting structure 4 on the rotating component 2.

[0038] like Figure 8 As shown, the rotation protection component 3 is provided with an anti-rotation mark 5 and a bidirectional rotatable mark 6; the anti-rotation mark 5 includes a clockwise anti-rotation mark 51 and a counterclockwise anti-rotation mark 52, and the bidirectional rotatable mark 6 is positioned between the clockwise anti-rotation mark 51 and the counterclockwise anti-rotation mark 52. Depending on the needs, the clockwise anti-rotation mark 51 and the counterclockwise anti-rotation mark 52 can be designed with conspicuous red or yellow markings, while the bidirectional rotatable mark 6 can be selected as a green marking; the anti-rotation limiting structure 4 can abut against the rotation protection component 3 to prevent the rotating part 2 from continuing to rotate relative to the stationary part 1 after rotating to a preset angle, and when the anti-rotation limiting structure 4 abuts against the rotation protection component 3, the state of the anti-entanglement device switches from the bidirectional rotatable mark 6 to the anti-rotation mark 5; and when the anti-rotation limiting structure 4 separates from the rotation protection component 3, the state of the anti-entanglement device is displayed as the bidirectional rotatable mark 6.

[0039] To this end, users can be effectively reminded of the status of the rotating part and obtain prompts for operation by switching between two-way rotatable and anti-rotation indicators: clockwise or counterclockwise? This makes the operation status visible, clear to the user, and ensures safe and reliable use.

[0040] like Figures 4-6 As shown, the rotation protection component 3 includes a rotation stop 31 that can be elastically rotated and reset. During the process where the rotation stop 31 and the anti-rotation limiting structure 4 are exactly abutting each other and the rotating component 2 continues to rotate to a preset angle and is stopped, the rotation stop 31 is elastically pushed and rotates with the rotating component 2 to the corresponding angle, so that the state of the device is switched from the bidirectional rotatable indicator 6 to the anti-rotation indicator 5.

[0041] likeFigures 8-9 Further, the rotating block 31 is in T-shaped structure, which comprises a sliding connecting part 311 and a stop rotating part 312 connected to the middle part of the sliding connecting part 311, and the bidirectional rotating mark 6 is arranged on the middle part of one side of the sliding connecting part 311, and the clockwise stop rotating mark 51 and the counterclockwise stop rotating mark 52 are arranged on the corresponding sides of the two end parts of the sliding connecting part 311 respectively.

[0042] As shown in the figure, Figure 5 The rotating protection assembly 3 further comprises a guide sliding groove 32, an elastic reset part 33 and a display window 34. The guide sliding groove 32 is provided with an avoiding gap 321 on the side facing the stop rotating limiting structure 4. The sliding connecting part 311 is arranged in the guide sliding groove 32 in a relative sliding manner. The stop rotating part 312 extends out of the avoiding gap 321 so that when the rotating part rotates relative to the stationary part, the stop rotating part 312 can resist the stop rotating limiting structure 4. The two ends of the guide sliding groove 32 and the corresponding two ends of the sliding connecting part 311 are respectively provided with the elastic reset part 33. The stop rotating mark 5 and the bidirectional rotating mark 6 are arranged on the sliding connecting part 311, and the display window 34 is arranged on the side of the sliding connecting part 311 provided with the stop rotating mark 5 and the bidirectional rotating mark 6. The two elastic reset parts 33 elastically press the sliding connecting part 311. Therefore, when the stop rotating part 312 is not pushed, the sliding connecting part 311 is balanced by the elastic force generated by the two elastic reset parts 33. At this time, the mark observed by the display window 34 is the bidirectional rotating mark 6.

[0043] In order to ensure that the sliding connecting part 311 is stably connected with the guide sliding groove 32, the rotating protection assembly 3 further comprises a stop guide groove 35 arranged on the side of the avoiding gap 321. The stop rotating part 312 is provided with a sliding guide part 3121 which is slidably arranged in the stop guide groove 35.

[0044] In order to make the rotation stable and the structure compact, the stationary part 1 is provided with a concave cavity for accommodating the rotating part 2. The stop rotating limiting structure 4 is a protruding structure arranged at the edge of the rotating part 2.

[0045] As shown in the figure, Figure 10 As a specific embodiment of the present application, it is an automobile child seat which comprises a seat body or a basket, and a rotatable anti-winding mechanism. The stationary part 1 is a base upper cover, and the rotating part 2 is a rotating disc. The basket or the seat body can be connected with the rotating disc through a detachable structure. The automobile child seat is provided with a stop rotating limiting structure 4 on the rotating disc, and a rotating protection assembly 3 on the base upper cover, so that the rotating disc can rotate relative to the base upper cover within a limited angle range. The angle range can be limited to 360° or more than 360° or other angles.

[0046] Because the rotating disc rotates to a preset angle relative to the upper cover of the base, the rotation limiting structure 4 pushes the rotating block 31 to elastically slide in the guide sliding groove 32, and therefore, the structure size of the rotation limiting structure 4 and the rotating block 31 can be designed to limit the rotating disc to rotate 360° in the clockwise direction or the counterclockwise direction relative to the upper cover of the base.

[0047] Similarly, the rotating disc can also be limited to rotate an angle greater than 360° in the clockwise direction or the counterclockwise direction relative to the upper cover of the base. With this scheme, when the basket or the seat body drives the rotating disc to rotate relative to the upper cover of the base, the wire connection between the upper cover of the base and the rotating disc can be effectively ensured to be reliable and not be pulled and broken or damaged, and the scheme has the characteristics of convenient manufacturing and cost economy; moreover, the user can effectively remind the user to know the state of the seat body by switching the display of the bidirectional rotating mark and the rotation limiting mark, and obtain the prompt that the operation can be performed, so that the operation state is visualized, and the user is clear and safe and reliable.

[0048] As shown in Figures 11-12 As another specific embodiment of the present application, it is a display or control panel, which comprises a rotatable anti-winding mechanism as described above, the stationary part 1 is a connecting seat, the rotating part 2 is a panel, and the rotating anti-winding device is arranged between the connecting seat and the panel so that the panel can rotate relative to the connecting seat within a limited angle range. Specifically, when it is a display, the user may watch or use the display from different angles according to his needs, which requires the display panel to be rotated relative to the connecting seat; when it is a control panel, the control panel is generally connected with the corresponding equipment, such as a CNC equipment, and the control panel can be rotated relative to the main body of the CNC equipment, and the user inputs and observes through the control panel. In many cases, the user will rotate the control panel to facilitate his own operation. Therefore, the display or control panel with the rotatable anti-winding mechanism can effectively avoid the wire winding problem, and can also effectively remind the user of the state of the rotating part through the corresponding mark.

[0049] In addition, the application of the rotatable anti-winding mechanism is not limited to automotive child safety seats, displays, control panels, but also includes other products that have not been exhausted.
