[0030] Please refer to Figures 1 to 3. The safety seat of the present invention includes a seat body 10 and a mounting seat 20. The mounting seat 20 can be installed on a car seat (not shown) by existing fixing methods such as ISOFIX. The seat body 10 is installed above the mounting seat 20. The mounting seat 20 has a front direction, a rear direction, a left direction and a right direction. The front direction or the rear direction is taken as the moving direction of the car, and the car door is located in the left direction or the right direction respectively. As needed, the seat body 10 can be locked to at least the first position or the second position of the mounting seat 20, or the seat body 10 can be released from the first position or the second position so that the seat body 10 can slide to the second position or the first position relative to the mounting seat 20, thereby changing the position of the seat body 10 relative to the car and making room for children to get on and off the car.

[0031] In one embodiment, the seat body 10 includes a seat plate 11, a backrest 12 and a connecting rod 13. The backrest 12 extends upward on one side of the seat plate 11 to form a bearing space. When in use, the child sits on the seat plate 11 and can lean on the backrest 12. The connecting rod 13 is passed through the side of the backrest 12 facing away from the seat plate 11 and is fixed thereto. In this embodiment, two opposite mounting blocks 121 are protruding from the side of the backrest 12 facing away from the seat plate 11, and the connecting rod 13 is passed between the two mounting blocks 121. The connecting rod 13 is connected to the mounting seat 20 to mount the seat body 10 on the mounting seat 20. In addition, the seat body 10 is not limited to being connected to the mounting seat 20 through the connecting rod 13, but can also be directly fixed to the mounting seat 20 by welding, screws, etc.; the seat body 10 can also be a carrying device such as a baby carrier in the prior art, and its orientation can be changed according to actual needs. For example, when a child sits, its orientation is to the front, and when an infant sits, the orientation can be changed to the rear, left or right direction; the plate surface of the seat plate 11 can be set to be parallel to the seat surface of the car seat, or have a certain inclination angle relative to the seat surface of the car seat to improve comfort.

[0032] Referring to Figures 4 and 5 , the mounting base 20 includes a base 21, a connecting plate 22, a sliding bracket 23, and a locking assembly 24. The connecting plate 22 is mounted on the base 21, the sliding bracket 23 is slidable relative to the connecting plate 22, the connecting rod 13 is fixedly connected to the sliding bracket 23 to secure the seat body 10 to the sliding bracket 23, and the locking assembly 24 is mounted on the sliding bracket 23 and is rotatable relative thereto. As the locking assembly 24 rotates relative to the sliding bracket 23, it engages with or disengages from the connecting plate 22, thereby locking or unlocking the sliding bracket 23 to or from the connecting plate 22.

[0033] Specifically, the base 21 has an outer bottom surface 211 on the side facing away from the seat body 10. This outer bottom surface 211 interfaces with the car seat during use. In one embodiment, the outer bottom surface 211 is parallel to a horizontal plane, and the axial direction of the connecting rod 13 is parallel to the outer bottom surface 211. The connecting plate 22 is mounted on and supported by the base 21.

[0034] The connecting plate 22 is located between the base 21 and the seat body 10. The connecting plate 22 is provided with a groove 221 and a fixing bracket 222. Referring to Figure 6, when projected in a direction perpendicular to the outer bottom surface 211, there are two or more grooves 221. Multiple grooves 221 are provided on the surface of the connecting plate 22 facing the seat body 10 and are arranged side by side in a straight line. The extending direction of the grooves 221 is perpendicular to the arrangement direction of the grooves 221. The locking assembly 24 can engage with each groove 221 in turn to lock the seat body 10 in the first position and the second position. Furthermore, there are three or more grooves 221 to lock the seat body 10 in multiple positions, such as a third position between the first position and the second position. Different grooves 221 correspond to different locking positions. In one embodiment, the connecting plate 22 and the base 21 are integrally formed. The connecting plate 22 is fixed relative to the base 21. The arrangement direction of each groove 221 is set to the front-to-back direction or the left-to-right direction according to the age of the child riding. The seat body 10 can slide in the front-to-back direction or the left-to-right direction along the arrangement direction of each groove 221. In another embodiment, the base 21 is hollow inside and has an opening (not marked) on the side facing the seat body 10. The inner bottom surface thereof is provided with a positioning column 212 protruding toward the connecting plate 22. The axis of the positioning column 212 is perpendicular to the outer bottom surface 211 and perpendicular to the extension direction of the groove 221. The connecting plate 22 is disc-shaped, and its middle portion protrudes into the interior of the base 21 toward the outer bottom surface 211. The connecting disk 22 is embedded in the base 21, and the positioning post 212 is inserted into the middle of the connecting disk 22. The axis of the connecting disk 22 coincides with the axis of the positioning post 212, so that the connecting disk 22 can rotate around the positioning post 212 relative to the base 21, and the base 21 supports the connecting disk 22. Furthermore, the number of columns of the grooves 221 is two or more, and they are symmetrically arranged on opposite sides of the positioning post 212. In addition, the connecting disk 22 can be connected to the base 21 by means of a movable latch or the like, and locked to the base 21 as needed, so that the connecting disk 22 can switch between a rotating state and a fixed state relative to the base 21. The locking of the connecting disk 22 on the base 21 can be specifically referred to the conventional settings of the prior art, and will not be described in detail here.

[0035] Please refer to Figure 7. The fixed bracket 222 protrudes from the disk surface of the connecting disk 22 facing the seat body 10, and its extension direction is parallel to the arrangement direction of the grooves 221. In one embodiment, the fixed bracket 222 is integrally formed with the connecting disk 22; in another embodiment, the fixed bracket 222 is a sheet metal part that is inserted into the connecting disk 22 and fixed thereto to increase strength. The fixed bracket 222 is provided with at least a first guide groove 2221 and a second guide groove 2222 whose extension directions are parallel to each other. The first guide groove 2221 and the second guide groove 2222 are respectively engaged with the sliding bracket 23 to guide the sliding of the sliding bracket 23. At least two guide grooves with parallel extension directions can ensure that the inclination angle of the sliding bracket 23 relative to the outer bottom surface 211 remains unchanged during the sliding process, thereby ensuring that the inclination of the seat body 10 relative to the car seat remains unchanged. Furthermore, projected along the extension direction of the groove portion 221, the first guide groove 2221 and the second guide groove 2222 extend parallel to each other and non-parallel to the outer bottom surface 211. This allows the seat body 10 to move away from or closer to the connecting plate 22 during sliding relative to the mounting base 20, thereby enhancing the ease of operation during sliding. Furthermore, there are two fixing brackets 222, symmetrically arranged on either side of the positioning post 212, with the groove portion 221 located between the two fixing brackets 222.

[0036] The sliding bracket 23 is located on one side of the fixed bracket 222 and is fixedly connected to the seat body 10. Its extension direction is parallel to that of the fixed bracket 222. It is provided with a first mounting hole 231, a second mounting hole 232, a support portion 233, a first protrusion 234, and a second protrusion 235. The connecting rod 13 is inserted into the first mounting hole 231 to secure the seat body 10 to the sliding bracket 23. The locking assembly 24 is inserted into the second mounting hole 232 and is rotatable about its axis. The rotation axis of the locking assembly 24 is parallel to the extension direction of the groove 221. The support portion 233 is located below the seat plate 11 to support the seat body 10. The first protrusion 234 and the second protrusion 235 are protruding from the side facing the fixed bracket 222 and are inserted into the first guide groove 2221 and the second guide groove 2222, respectively. In one embodiment, the second mounting hole 232 is located near the outer edge of the connecting plate 22 for easier operation. Furthermore, the sliding bracket 23 is provided with a fixing plate 236, which is fixed to the surface of the seat plate 11 facing the connecting plate 22 by screws or other means. The locking assembly 24 sequentially passes through the second mounting hole 232 and the fixing plate 246 and is fixed thereto to strengthen the fixation between the sliding bracket 23 and the seat body 10. Furthermore, there are two sliding brackets 23, symmetrically arranged on the side of the fixing bracket 222 facing away from the groove 221, and the locking assembly 24 is inserted between the two sliding brackets 23. Furthermore, the first mounting hole 231 and the second mounting hole 232 are elongated holes, and the position of the connecting rod 13 and / or the locking assembly 24 within the first mounting hole 231 and / or the second mounting hole 232 can be adjusted according to the size of the seat body 10 to accommodate seat bodies 10 of different sizes. In addition, it can be understood that, as needed, the first protrusion 234 and the second protrusion 235 can be changed to be set on the fixed bracket 222, and correspondingly, the first guide groove 2221 and the second guide groove 2222 can be changed to be set on the sliding bracket 23 to also achieve the guiding effect.

[0037] Referring to Figure 8 , the locking assembly 24 includes a handle 241, a locking rod 242, a rotating rod 243, and a torsion spring 244. The locking rod 242 and the rotating rod 243 are disposed through the handle 241, with their axes parallel to the extension direction of the groove 221. The rotating rod 243 is hingedly connected to the sliding bracket 23 and is located near the outer edge of the connecting plate 22. The handle 241 is hingedly connected to the sliding bracket 23 via the rotating rod 243. The locking rod 242 is located near the interior of the connecting plate 22. The side of the handle 241 away from the locking rod 242 is a pulling portion 2411. When the seat body 10 is facing forward, the pulling portion 2411 is located near the front, and the locking rod 242 is located near the rear. Pulling the pulling portion 2411 downward toward the connecting plate 22 causes the handle 241 to rotate about the rotating rod 243, causing the locking rod 242 to engage or disengage from one of the slots 221. The torsion spring 244 is mounted on the rotating rod 243, with its ends abutting against the connecting plate 22 and the seat body 10, respectively. The elastic force of the torsion spring 244 exerted on the rotating rod 243 keeps the locking rod 242 turned toward the slot 221 when the handle 241 is not pulled, preventing the locking assembly 24 from automatically unlocking. Preferably, there are two torsion springs 244, one located on either side of the rotating rod 243 along the axial direction.

[0038] Furthermore, referring to Figure 9 , the safety seat also includes an unlocking assembly 30, which includes a push-pull plate 31 and a return spring 32. The push-pull plate 31 is mounted on the side of the seat plate 11 facing the mounting seat 20 and can slide along the surface of the seat plate 11 away from the backrest 12. The push-pull plate 31 extends from the center of the seat plate 11 to the outer edge. A pressure block 311 is provided on the side near the center of the seat plate 11, protruding toward the mounting seat 20. A recess 312 is provided on the side away from the center of the seat plate 11, recessed toward the seat body 10. The pressure block 311 is located between the pulling portion 2411 and the rotating rod 243. The side facing the pulling portion 2411 is inclined, and the distance between the pressure block 311 and the pulling portion 2411 gradually increases from the seat plate 11 toward the connecting plate 22. Reaching into the recess 312 and pulling the push-pull plate 31 away from the backrest 12, the pressure block 311 approaches the pull portion 2411 and gradually presses it toward the connecting plate 22, thereby causing the locking rod 242 to leave the groove 221, unlocking the seat. Pushing the push-pull plate 31 in the opposite direction causes the pressure block 311 to leave the pull portion 2411. Under the action of the torsion spring 244, the locking rod 242 rotates toward the groove 221, locking the seat. A return spring 32 connects the push-pull plate 31 and the seat plate 11. When the push-pull plate 31 is pulled away from the backrest 12, the return spring 32 generates a spring force that pushes the pressure block 311 away from the pull portion 2411. After releasing the push-pull plate 31, the pressure block 311 automatically leaves the pull portion 2411 under the action of the return spring 32.

[0039] Based on the above structure, the position adjustment of the safety seat on the car seat is described through the following embodiments.

[0040] Example 1:

[0041] In this embodiment, the grooves 221 are arranged along the left and right sides of the seat body 10, the pull portion 2411 is located on the side closest to the vehicle door, and the seat pan 11 is tilted. While the vehicle is in motion, the locking assembly 24 engages with the mounting base 20, locking the seat body 10 thereon. When getting on or off the vehicle, the push-pull plate 31 is pulled, causing the handle 241 to rotate about the rotating rod 243, and the locking rod 242 to separate from the connecting plate 22. The seat body 10 is unlocked from the mounting base 20. Pulling the seat body 10 left or right allows it to be moved out of the vehicle door while maintaining its tilt. After releasing the push-pull plate 31, the locking rod 242 reengages the grooves 221, returning the seat body 10 to its locked position. This allows children to enter and exit the vehicle in a stable manner. Furthermore, since the tilt of the seat pan 11 remains unchanged during movement, the child is less likely to be disturbed.

[0042] Example 2:

[0043] In this embodiment, the connecting plate 22 is rotatable relative to the base 21. While the car is moving, the connecting plate 22 can be rotated so that the child faces forward, and the handle 241 is turned to the front position, and the seat body 10 is locked. When getting on or off the car, the connecting plate 22 can be rotated first so that the child faces the car door, and the handle 241 is then turned to the left or right position. Then, the push-pull plate 31 is pulled, and the handle 241 rotates around the rotating rod 243, and the locking rod 242 leaves the connecting plate 22. The seat body 10 is unlocked on the mounting base 20. Then, after pulling the seat body 10 toward the car door, the push-pull plate 31 is released, and the locking rod 242 re-engages the groove 221, and the seat body 10 returns to the locked state, so that the seat body 10 can move closer to the car door and maintain a stable locked state when the child gets on or off the car.

[0044] Compared with the prior art, the safety seat mounting base and the safety seat of the present invention have the following advantages:

[0045] 1. The position of the seat body in the car can be adjusted as needed to improve the convenience and stability of getting on and off the car;

[0046] 2. Locking and unlocking operations are convenient and simple;

[0047] 3. The direction of the seat body can be adjusted at will;

[0048] 4. The locking component can remain locked when there is no external force, which is highly safe.

[0049] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
