The disk frame 6 has a disk frame body 60, and the upper surface of the disk frame 6 is provided with at least one blocking lock groove 61 adapted to the bottom end of the wedge lock 7. The wedge lock 7 has different states of being engaged or separated with the locking hole 31 or the blocking lock groove 61, and the locking or unlocking of the sliding plate 3 or the rotating disk 5 is controlled by the wedge lock 7; when the bottom end of the wedge lock 7 is separated from the blocking lock groove 61, the bottom end of the wedge lock 7 presses against the upper surface of the disk frame 6 (see Figure 5A , 5B , 5F), the top end of the wedge lock 7 extends upward into the lock hole 31 (see Figure 8 , 9, 9A, 9B), the sliding plate 3 is locked on the slide rail plate 4, and at this time, the rotating disk 5 can drive the slide rail plate 4 and the sliding plate 3 to rotate synchronously; when the wedge lock 7 rotates with the rotating disk 5 to the position where the bottom end of the wedge lock corresponds to the blocking lock groove 61, the bottom end of the wedge lock 7 enters the blocking lock groove 61 downward (see 7A, 7C, 7D), locking the rotating disk 5, and at the same time, the top end of the wedge lock 7 escapes from the lock hole 31 (see Fig.10 , 12 , 12A, 12B), unlock the sliding plate 3, at this time, the sliding plate 3 drives the carrier body frame 1 to slide to the side of the carrier under the action of external force, so as to facilitate the infant to be taken out of the carrier; rotate the rotating plate 5, and when the rotating plate 5 rotates, it drives the wedge lock 7 to overcome the resistance between the bottom end of the wedge lock and the blocking lock groove 61, and pushes the bottom end of the wedge lock 7 out of the blocking lock groove 61, unlocking the rotating plate 5. The side of the carrier base 9 is provided with a side shift notch 91 for the sideways movement of the sliding plate 3.
[0063] In this embodiment, the wedge lock 7 is a locking member for both the rotating disk 5 and the sliding plate 3, and has multiple functions. When the wedge lock 7 locks the rotating disk 5, the sliding plate 3 is unlocked, and the rotating disk 5 is locked on the disk frame 6, so that the lateral movement of the sliding plate 3 is smoother; when the wedge lock 7 locks the sliding plate 3, the rotating disk 5 is unlocked from the disk frame 6, so that the rotating disk 5 drives the sliding plate 3 to rotate to the forward position or the backward position.
[0064] In this embodiment, there are two wedge locks 7, and the two wedge locks 7 are evenly arranged on the same circumference; there are also two blocking lock grooves 61 opened on the disk frame 6, and the two blocking lock grooves 61 are evenly arranged on the same circumference; after the rotating disk 5 rotates 90° or 270°, the bottom end of the wedge lock 7 enters the blocking lock groove 61, and at this time the carrier is converted from an infant carrying state to an infant holding state, and the carrier body frame 1 and the sliding plate 3 can slide along the lateral displacement direction S which is basically perpendicular to the vehicle travel direction F.
[0065] In this embodiment, the bottom end of the wedge lock 7 is a trapezoidal shape that is wide at the top and narrow at the bottom, and the bottom end inclined surface 72 of the wedge lock 7 is arranged obliquely, and the corresponding blocking lock groove 61 is also a trapezoidal shape that is wide at the top and narrow at the bottom, and the blocking lock groove inclined surface 611 of the blocking lock groove 61 is also arranged obliquely. The bottom end of the wedge lock 7 can also be in an arc shape or a truncated cone shape, and the corresponding blocking lock groove 61 is also in an arc shape or a truncated cone shape.
[0066] In this embodiment, the wedge lock 7 also has a push-reset spring 71, which is located between the slide rail plate 4 and the rotating disk 5. The lower end of the push-reset spring 71 is connected to the wedge lock 7, and the upper end is connected to the bottom surface of the slide rail plate 4. The push-reset spring 71 always applies downward pressure to the wedge lock 7. When the wedge lock 7 rotates with the rotating disk 5 to a position where the bottom end of the wedge lock 7 corresponds to the blocking lock groove 61, the wedge lock 7 automatically moves downward into the blocking lock groove 61.
[0067] In this embodiment, the sliding plate 3 and the slide rail plate 4 are connected by a slide rail pair, and the slide rail pair includes a straight tube rail 45 arranged on the edge of the slide rail plate 4 and a sleeve 32 arranged on the edge of the sliding plate 3. The sleeve 32 is sleeved on the straight tube rail 45, and the sliding plate 3 can move along the length direction of the straight tube rail 45 under the action of external force.
[0068] A slide plate locking unit is also provided between the slide plate 3 and the slide rail plate 4. Figure 1 , Figure 2 , Figures 10 to 14A As shown, the skateboard locking unit includes at least one skateboard locking assembly 33 arranged on the sliding plate 3 and at least one slide rail locking groove 42 arranged on the upper surface of the slide rail plate 4. The skateboard locking assembly 33 includes a skateboard lock 333 arranged vertically. The bottom end of the skateboard lock 333 is adapted to the slide rail locking groove 42. When the bottom end of the skateboard lock 333 enters the slide rail locking groove 42, the sliding plate 3 is locked; when the sliding plate 3 is pushed, the skateboard lock 333 overcomes the resistance between the bottom end of the skateboard lock 333 and the slide rail locking groove 42 under the action of external force, and the bottom end of the skateboard lock 333 is pushed out from the slide rail locking groove 42 to unlock the sliding plate 3.
[0069] The bottom end of the slide plate lock 333 is a trapezoidal shape that is wide at the top and narrow at the bottom. The slide plate lock bottom end inclined surface 3331 of the slide plate lock 333 is set obliquely. The corresponding slide rail lock groove 42 is also a trapezoidal shape that is wide at the top and narrow at the bottom. The slide rail lock groove inclined surface 421 of the slide rail lock groove 42 is set obliquely.
[0070] The bottom end of the slide plate lock 333 may also be in other shapes, such as Fig.13 , Fig.14 and Fig.14A As shown, another inclined surface 3331 at the bottom of the slide lock / The arc shape is adopted, and the corresponding other slide rail locking groove 42 / The arc shape is also adopted. Both can also adopt the truncated cone shape.
[0071] In this embodiment, the skateboard locking assembly 33 also includes a lock seat 331 and a return spring 332. The lock seat 331 is fixedly installed on the sliding plate 3. The lock seat 331 has a seat cavity. The return spring 332 is located in the seat cavity. The bottom end of the return spring 332 is connected to the skateboard lock 333, and the top end is connected to the top surface of the seat cavity.
[0072] The slide plate lock 333 also has a travel control protrusion 3332 . A travel control groove 3311 is formed on the side of the lock base 331 . The travel control protrusion 3332 is located in the travel control groove 3311 to control the distance that the slide plate lock 333 moves up and down.
[0073] There are multiple slide rail locking grooves 42, among which the slide rail locking groove located at the end is the end slide rail locking groove 43. The inclination angle of the end slide rail locking groove 43 is greater than the inclination angle of the remaining slide rail locking grooves 42, thereby generating a greater friction resistance with the slide plate lock 333. When the bottom end of the slide plate lock 333 enters the end slide rail locking groove 43, the sliding plate 3 reaches the maximum moving stroke.
[0074] A plurality of rollers 44 are further disposed on the upper surface of the slide rail plate 4 and / or the lower surface of the sliding plate 3 . Preferably, the plurality of rollers 44 are arranged in at least one row along the moving direction of the sliding plate 3 .
[0075] In practice, after the car stops, the rotating disk 5 and the disk frame 6 are locked in the lateral movement direction S only to make the sliding plate 3 more stable when moving sideways. Therefore, the locking of the rotating disk 5 and the disk frame 6 only needs to meet general requirements. During the driving process of the car, the rotating disk 5 must be located in the forward position or the rearward position. At this time, the locking of the rotating disk 5 and the disk frame 6 in the forward position or the rearward position must be firm to avoid failure to provide protection for infants and young children in the event of an accident.
[0076] Therefore, the rotating disk 5 also has a first track locking mechanism for locking the rotating disk 5 and the disk frame 6 in the forward position or the backward position. Figures 1 to 7D As shown, the first-track locking mechanism includes two handles 8, a transmission mechanism and a turntable lock 52. The turntable lock 52 is vertically arranged, and a disk frame lock groove 62 adapted to the turntable lock 52 is opened on the disk frame 6. The transmission mechanism is connected to the handle 8 and the turntable lock 52 respectively. The handle 8 controls the lock head of the turntable lock 52 to move up and down through the transmission mechanism to achieve locking or separation with the disk frame lock groove 62.
[0077] There is one turntable lock 52 and two disk frame lock slots 62 . The two disk frame lock slots 62 are evenly arranged on the same circumference. After the rotating disk 5 rotates 180°, the turntable lock 52 corresponds to one of the disk frame lock slots 62 .
[0078] The transmission mechanism includes a first rotating cam 53, a transmission cam 54, a connecting rod 55, a second rotating cam 56, a locking joint 57 and a locking seat 59. The first rotating cam 53, the transmission cam 54 and the second rotating cam 56 are all installed on the rotating disk 5 through a hinge shaft. There are two handles 8, and the two handles 8 are respectively connected to the first rotating cam 53 and the second rotating cam 56 (see Figure 5 , 5C , 5D), one of the first rotating cam 53 and the second rotating cam 56 is directly hinged to one end of the connecting rod 55, and the other is hinged to the other end of the connecting rod 55 through the transmission cam 54; so that when the first rotating cam 53 and the second rotating cam 56 rotate in opposite directions respectively, they can both drive the connecting rod 55 to move in the same direction.
[0079] In this embodiment, by rotating the first rotating cam 53 counterclockwise (R1) by one of the handles 8, the transmission cam 54 can be driven to rotate clockwise (R2), thereby pulling the connecting rod 55 to move in the direction of D1. By rotating the second transmission cam 56 clockwise (R3) by the other handle 8, the connecting rod 55 can also be pulled to move in the direction of D1. The connecting rod 55 is preferably formed by two rods fixedly connected, so that during manufacturing and assembly, the two rods pass through the openings provided on the rotating disk 5 respectively, so that the connecting rod 55 is guided by the opening of the rotating disk 5 when moving and is more stable.
[0080] The connecting rod 55 is connected to a lock joint 57, and the lock joint 57 is provided with an inclined slot 571; when the connecting rod 55 moves, the lock joint 57 is driven, and a turntable lock 52 that can only move up and down is driven by the inclined slot 571 to move up or down (see Figure 4 ), thereby realizing the locking or separation between the rotating disk lock 52 and the disk frame lock slot 62. The connecting rod 55 is also connected to a return spring.
[0081] In this embodiment, the rotating disk 5 is provided with a fixed lock seat 59, and the fixed lock seat 59 is provided with a vertical slot 591. The turntable lock 52 has a locking pin 58, and the locking pin 58 passes through the oblique slot 571 and the vertical slot 591. The middle part of the locking pin 58 is fixedly inserted into the turntable lock 52, and the locking pin 58 is driven to move up and down by the joint action of the oblique slot 571 and the vertical slot 591. When the locking pin 58 moves up and down, it drives the turntable lock 52 to move up and down synchronously.
[0082] like Figure 3 , 3A , 5A and 5E, the rotating disk 5 is in the locked position, and the rotating disk lock 52 is located in the disk frame lock slot 62. When the rotating disk 5 needs to be unlocked, one of the handles 8 can be turned, and of course, the two handles 8 can be turned in opposite directions at the same time. Figure 6 , 6A , as shown in 7A and 7B.
[0083] When the rotating disk 5 needs to be locked, just release the handle 8. Under the action of the reset spring, the connecting rod 55 moves in the reverse direction, driving the lock joint 57 to move in the reverse direction. During the movement, the locking pin 58 and the rotating disk lock 52 move downward through the combined action of the inclined slot 571 and the vertical slot 591. The rotating disk lock 52 enters the locking slot 62 of the disk frame, locking the rotating disk 5 (see Figure 3A , 5A , 5E).
[0084] In this embodiment, the wedge lock 7 is also the second locking mechanism of the rotating disk 5, and the first locking mechanism needs to be unlocked first when rotating.
[0085] like Fig.18As shown, the rotating disk 5 is locked on the disk frame 6 through the head locking mechanism. At this time, the bottom end of the wedge lock 7 is separated from the blocking lock groove 61, the bottom end of the wedge lock 7 presses against the upper surface of the disk frame 6, and the top end of the wedge lock 7 extends upward into the lock hole 31, locking the sliding plate 3 on the slide rail plate 4. The carrier body moves along the driving direction F, and the infant is in a normal carrying state.
[0086] When the infant needs to be taken out of the carrier, the first locking mechanism is unlocked, and then the rotating disk 5 is rotated. When the rotating disk 5 rotates, the slide plate 4 and the sliding plate 3 can be driven to rotate synchronously; after the rotating disk 5 rotates 90° or 270°, the carrier body rotates from the driving direction F to the lateral movement direction S, such as Fig.19 As shown, at this time, the bottom end of the wedge lock 7 enters downward into the blocking lock groove 61 to lock the rotating disk 5, and at the same time the top end of the wedge lock 7 escapes from the lock hole 31 to unlock the sliding plate 3.
[0087] Push the sliding plate 3 to drive the carrier body frame 1 to slide toward the side of the carrier. Fig. 20 As shown, at this time, the infant is transformed from a normal carrying state to a holding state. Since the carrier body is already located in the lateral movement direction S, it is convenient to hold the infant out of the carrier.
[0088] When it is necessary to reset, push the sliding plate 3 back to reset, and then rotate the rotating disk 5. When the rotating disk 5 rotates, it drives the wedge lock 7 to overcome the resistance between the bottom end of the wedge lock and the blocking lock groove 71, and pushes the bottom end of the wedge lock 7 out of the blocking lock groove 71 to unlock the rotating disk 5. At the same time, the top end of the wedge lock 7 extends upward into the lock hole 31 to lock the sliding plate 3 on the slide rail 4. At this time, continue to rotate the rotating disk 5 and rotate it back to the initial position. At the initial position, the infant is in a normal carrying state, and the rotating disk 5 is locked by the first locking mechanism.
