[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicate positions or location relationships based on the positions or location relationships during normal use of the product.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. The drawings of the embodiments of the present invention are provided with a coordinate system XYZ, wherein the positive direction of the X-axis represents the left, the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front, the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top, and the negative direction of the Z-axis represents the bottom.

[0029] An embodiment of the present utility model provides a chair body rotation structure, as shown in Figures 1 to 9, comprising a base 1, a rotating disk assembly 2, an electric rotating assembly 3 and a manual rotating assembly 4, wherein the rotating disk assembly 2 comprises a rotating disk 21, a gear disk 22 and a locking assembly 23 for locking or unlocking the relative positions of the rotating disk 21 and the gear disk 22, the rotating disk 21 being suitable for being connected to the chair body, and the gear disk 22 being connected to the base 1; when the rotating disk 21 and the gear disk 22 are locked with each other, the electric rotating assembly 3 drives the gear disk 22 to drive the chair body to rotate relative to the base 1; when the rotating disk 21 and the gear disk 22 are unlocked from each other, the manual rotating assembly 4 drives the rotating disk 21 to drive the chair body to rotate relative to the base 1.

[0030] Among them, an axis is provided on the base 1 for the installation of the gear plate 22 to realize the rotation of the gear plate 22 relative to the base 1, and the gear plate 22 can rotate 360° in the forward or reverse direction around the axis; the electric rotating component 3 can drive the gear plate 22 to rotate relative to the base 1 only when it is powered on. At this time, the rotating disk 21 and the gear plate 22 are locked with each other to realize the electric rotation of the chair body relative to the base 1. When the electric rotating component 3 stops working, pushing the chair body cannot cause the gear plate 22 to rotate relative to the base 1; when the electric rotating component 3 stops working and the rotating disk 21 and the gear plate 22 are unlocked from each other, manually pushing the chair body can realize the rotation of the rotating disk 21 relative to the gear plate 22, so as to realize the rotation of the chair body relative to the base 1.

[0031] The chair body rotation structure in this embodiment is configured to lock or unlock the rotating disk 21 and the gear disk 22 with each other through a locking assembly 23, combining the electric and manual rotation modes, so that parents or users can choose a suitable rotation mode according to actual needs. The electric rotation mode is suitable for daily use, and the rotation of the chair body can be achieved through the electric rotation assembly 3, while the manual rotation mode provides a backup rotation mode when the electric rotation assembly 3 stops working, is not restricted by the power supply, and improves the convenience, safety and flexibility of the child safety seat.

[0032] Optionally, as shown in Figure 1, a slip ring 5 for power supply and communication is installed on the base 1. The slip ring 5 includes a slip ring body and wires that are rotatably connected to each other. The wires are suitable for being electrically connected to the seat. The slip ring body is connected to the base 1, and the rotating disk 21 is provided with a wire hole 211 for the wires to pass through.

[0033] Among them, the wires of the slip ring 5 can rotate 360° unlimitedly relative to the slip ring body. One end of the slip ring 5 is electrically connected to the power supply, which can be a self-contained power supply (such as a battery pack) or a vehicle-mounted power supply. The other end is electrically connected to the seat through wires to realize communication and power supply to the seat; the wire hole 211 is preferably arranged at the center position of the rotating disk 21 so that the wires of the slip ring 5 can pass through and the wiring is short; this embodiment uses the slip ring 5 to realize power supply and communication of the seat, which will not affect the rotation of the rotating disk 21, can prevent the wires from being hooked, and realize the free rotation of the seat, and the wires can be rotated at any angle, so that the wires can basically remain in their original state during the rotation of the rotating disk 21, ensuring that power supply and communication are not interfered with, effectively improving the service life of the wires, and avoiding damage that affects the normal use of the seat.

[0034] Optionally, in combination with Figures 1, 5, 7 and 9, the electric rotation assembly 3 includes a drive motor 31 and a worm gear assembly 32 that are transmission-connected to each other, the worm gear assembly 32 includes a worm wheel 321 and a worm 322 that are meshed with each other, the worm 322 is connected to the motor shaft of the drive motor 31, and the gear plate 22 is provided with an internal gear ring 221 that is meshed with the worm wheel 321.

[0035] The worm 322 is fixedly connected to the motor shaft of the driving motor 31, and the inner gear ring on the gear plate 22 is meshed with the worm wheel 321. The driving motor 31 drives the worm 322 to rotate synchronously, and the worm 322 drives the worm wheel 321 to rotate synchronously. The worm wheel 321 is meshed with the inner gear ring 221 to drive the gear plate 22 to rotate synchronously, and finally realizes the electric rotation function of the seat; an axis for the worm wheel 321 to rotate is provided on the base 1; and the matching structure of the worm wheel 321 and the worm 322 has a self-locking function. When the driving motor 31 stops driving the worm 322 to rotate at any angle, the gear plate 2 2 will be locked at any angular position, because the worm wheel 321 cannot reversely drive the worm 322. When the worm 322 is locked, the inner gear ring 221 of the gear plate 22 is locked with the worm wheel 321, thereby realizing the automatic locking function. The driving motor 31, the worm wheel 321 and the worm 322 are all arranged on the inner side of the gear plate 22, which not only can reasonably arrange the seat structure, but also because the diameter of the worm wheel 321 arranged on the inner side is definitely smaller than the diameter of the inner gear ring 221 of the gear plate 22, the structure in which the small gear drives the large gear to rotate is also a good labor-saving mechanism.

[0036] Optionally, in combination with Figures 1, 2, and 9, a circuit board is also included, the electric rotation component 3 includes a drive motor 31, a position signal sensor 6 is provided on the base 1, and the gear plate 22 is provided with a plurality of position signalers arranged at intervals, and one of the plurality of position signalers is selectively sensed and cooperated with the position signal sensor 6, and the position signal sensor 6 and the drive motor 31 are both electrically connected to the circuit board.

[0037] Among them, when the seat rotation angle reaches the set required angle, the position signal sensor 6 on the base 1 and the corresponding position signal on the gear plate 22 generate an induction signal, and the circuit board controls the drive motor 31 to stop working after receiving the corresponding signal; the position signal sensor 6 and the position signal are implemented using RFID technology, that is, the position signal sensor 6 is a reader / writer, and the position signal is an electronic tag, and each position signal is unique, so that the position signal sensor 6 can accurately detect the rotation angle position of the seat; in this embodiment, the number of position signalers is preferably four, corresponding to the forward position of the seat, the right position of the seat, the backward position of the seat and the left position of the seat.

[0038] Optionally, as shown in Figures 2 to 9 , the manual rotation assembly 4 includes a linkage seat 41 and a release switch 42 that are movably connected to each other. The linkage seat 41 is movably connected to the rotating disk 21. When the linkage seat 41 moves relative to the rotating disk 21, the release switch 42 causes the locking assembly 23 to unlock or lock. When the linkage seat 41 moves relative to the rotating disk 21, the release switch 42 translates or rotates, thereby causing the locking assembly 23 to unlock or lock. This structure is simple and reliable.

[0039] Optionally, in combination with Figures 2 to 9, the linkage seat 41 is provided with a slide groove 411 and an inclined groove 412, the rotating disk 21 is provided with a track 212 that is slidably connected to the slide groove 411 front and back, and the release switch 42 is provided with a movable pin 421 that is slidably connected to the inclined groove 412. When the linkage seat 41 moves in the front and rear directions, the release switch 42 moves in the left and right directions under the cooperation of the movable pin 421 and the inclined groove 412, so that the release switch 42 drives the locking assembly 23 to unlock or lock.

[0040] Among them, taking the initial position of the chair body as a reference, the length direction of the slide groove 411 is consistent with the front-to-back direction, the number of the inclined grooves 412 is two, the two inclined grooves 412 are symmetrically arranged, and the two inclined grooves 412 are in an eight-shaped shape as a whole; in the initial locked position, the movable pin 421 cooperates with the front end of the inclined groove 412, and when unlocked, the movable pin 421 cooperates with the rear end of the inclined groove 412, that is, when the linkage seat 41 moves forward, the two release switches 42 approach each other to unlock the locking assembly 23, and when moving backward, the two release switches 42 move away from each other to lock the locking assembly 23.

[0041] Optionally, as shown in Figures 3 and 7, the manual rotation assembly 4 further includes a pull wire 43 and a first reset member 44. The two ends of the first reset member 44 are respectively connected to the rotating disk 21 and the linkage seat 41, and the pull wire 43 is connected to the linkage seat 41. The first reset member 44 is preferably a compression spring. One end of the pull wire 43 is fixedly connected to the linkage seat 41, and the other end is fixedly connected to the seat handle. The user can pull the pull wire 43 forward to drive the linkage seat 41 forward, thereby unlocking the locking assembly 23 and realizing manual rotation operation. At this time, the first reset member 44 is in a compressed state. After the pull wire 43 is released, the spring force of the first reset member 44 pushes the linkage seat 41 to automatically reset, so that the locking assembly 23 is re-locked.

[0042] Optionally, in combination with Figures 2, 5, 6 and 7, the locking assembly 23 includes a rotary gear pin 231 and a second reset member 232, the gear plate 22 is provided with an axial groove 222 for the hinged connection of the rotary gear pin 231, and the two ends of the second reset member 232 are respectively connected to the axial groove 222 and the rotary gear pin 231, the rotating plate 21 is provided with a gear groove 213 suitable for cooperating with the rotary gear pin 231, and the unlocking switch 42 is movably installed in the gear groove 213. The second reset member 232 is preferably a compression spring; the rotation gear pin 231 is hingedly connected to the shaft groove 222 for locking the relative position between the rotating disk 21 and the gear disk 22. The number of the rotation gear pins 231 is not less than two so that the chair body can be positioned at different angles; the gear groove 213 is used to cooperate with the rotation gear pin 231 for locking. The number of the gear groove 213 is not less than one, and there are two in this embodiment, so that the angle positioning of the chair body is more stable and reliable; the shaft groove 222 has a certain depth to accommodate the rotation gear pin 231. When locked, the rotation gear pin 231 moves out of the shaft groove 222 and is locked into the gear groove 213 under the elastic force of the second reset member 232 for electric rotation; when unlocked, the rotation gear pin 231 moves out of the gear groove 213 and enters the shaft groove 222 for manual rotation; the release switch 42 can move left and right in the gear groove 213 to drive the rotation gear pin 231 in and out of the gear groove 213. The structure of the locking assembly 23 is simple and reliable.

[0043] In this embodiment, when consumers take their children in and out of the car with a child safety seat, they can achieve the desired rotation position through electric rotation adjustment. When rotating through electric adjustment, the rotating disk 21 is fixed to the gear disk 22 through the rotating gear pin 231 to form a whole. When the drive motor 31 drives the worm 322, the worm 322 drives the worm wheel 321 to rotate, and the gear disk 22 rotates under the drive of the worm wheel 321. The chair body rotates through the rotating disk 21. When the rotation angle of the chair body reaches the set required angle, the position signal sensor 6 on the base 1 and the corresponding position sensor on the rotating disk 21 generate signals, and the motor stops working.

[0044] Optionally, in combination with Figures 2, 3, and 6, the release switch 42 is provided with a first slope surface 422, and the rotary gear pin 231 is provided with a second slope surface 2311 suitable for abutting against the first slope surface 422. The two slope surfaces abut against each other to achieve mutual pushing of the release switch 42 and the rotary gear pin 231. When the locking assembly 23 is unlocked, the first slope surface 422 contacts the second slope surface 2311, pushing the rotary gear pin 231 out of the gear slot 213. The first and second sloping surfaces 422 and 2311 of the first and second sloping surfaces 2311 do not contact each other, and the rotating gear pin 231 can be firmly stuck in the gear groove 213 under the action of the second reset member 232, thereby completing the switching of the chair body angle.

[0045] When the child safety seat is in a power-off state, the consumer can manually adjust the swivel seat by pulling the handle, which drives the pull wire 43, and the pull wire 43 drives the linkage seat 41, and the linkage seat 41 slides forward. At this time, the release switch 42 is driven by the inclined groove 412 on the linkage seat 41 to move inward. As a result, the rotation gear pin 231 and the rotation release switch 42 slide on the slope surface, and the rotation gear pin 231 rotates and disengages from the gear groove 213 on the rotating disk 21. At this time, the gear disk 22 is in a stationary state due to self-locking, and the drive motor 31 is in a power-off state. The rotating disk 21 starts to rotate relative to the gear disk 22. When it rotates to the required gear, the rotation gear pin 231 is automatically locked in the gear groove 213 on the corresponding rotating disk 21 through the second reset member 232 below, and the rotation movement is completed.

[0046] Another embodiment of the present invention provides a child safety seat, comprising the seat body rotating structure described above.

[0047] The child safety seat in this embodiment is provided with a locking assembly 23 to lock or unlock the rotating disk 21 and the gear disk 22 with each other, combining the electric and manual rotation modes, so that parents or users can choose the appropriate rotation mode according to actual needs. The electric rotation mode is suitable for daily use, and the rotation of the chair body can be achieved through the electric rotation assembly 3, while the manual rotation mode provides a backup rotation mode when the electric rotation assembly 3 stops working, is not restricted by the power supply, and improves the convenience, safety and flexibility of the child safety seat.
