Description

Technical Field

[0001] This invention relates to the field of automotive seat technology, and in particular to a safety seat mounting bracket and a safety seat. Background Technology

[0002] With cars becoming increasingly common in people's lives, for safety reasons, children are generally placed in car seats in the back seat when riding in a car. However, due to the limitations of interior space and door width, especially in small vehicles, fixed car seats not only take up most of the interior space, but also make it easier for children to collide with the car when getting in and out, increasing the inconvenience of getting in and out of the vehicle. Summary of the Invention

[0003] Therefore, the purpose of this invention is to provide a safety seat mounting base, which allows the seat body mounted thereon to slide as needed, thereby improving the convenience of getting in and out of the vehicle.

[0004] The technical solution adopted in this invention is as follows:

[0005] A child safety seat mounting bracket includes a base, a sliding bracket, and a locking assembly; the sliding bracket is located above the base and is slidable relative to the base; the locking assembly is hinged to the sliding bracket and is rotatable relative to it; as the locking assembly rotates, the sliding bracket locks onto the base or unlocks from the base.

[0006] Compared with the prior art, the safety seat mounting bracket of the present invention can lock the sliding bracket to a suitable position on the base during the vehicle's operation. When getting in and out of the vehicle, the bracket can be unlocked and slid to a position that facilitates getting in and out, and then locked, thereby increasing the usable space inside the vehicle, reducing the possibility of collisions when getting in and out of the vehicle, and because the sliding bracket is in a locked state during the process of getting in and out of the vehicle, it has high stability.

[0007] In one embodiment, the base has a front direction, a rear direction, a left direction, and a right direction. The sliding bracket can slide on the base along the left direction or the right direction, and the tilt angle of the sliding bracket relative to the base remains unchanged during the sliding process, further improving the stability when getting on and off the vehicle.

[0008] In another embodiment, the locking assembly includes a handle and a locking lever; the locking lever passes through the handle; the handle has a pull portion on the side near the outer edge of the base; the handle is hinged to the sliding bracket, and the hinge point is located between the locking lever and the pull portion, with the hinge axis parallel to the axis of the locking lever; pulling the pull portion causes the locking lever to rotate about the hinge axis between the handle and the sliding bracket, and engage with or disengage from the base, thereby locking or unlocking the sliding bracket on the base.

[0009] In another embodiment, a connecting plate is also included; the connecting plate is mounted between the base and the sliding bracket and is rotatable relative to the base to facilitate changing the orientation of the seat body when getting in and out of the vehicle.

[0010] In another embodiment, the base has a plurality of slots on its upper surface, the slots being arranged side by side along a straight line, and the extension direction of the slots being perpendicular to the arrangement direction of the slots. The locking component can be sequentially engaged into each slot to lock it in place.

[0011] In another embodiment, a fixed bracket protrudes from the base, the extension direction of the fixed bracket being parallel to the arrangement direction of the grooves; one of the sliding bracket or the fixed bracket is provided with at least a first guide groove and a second guide groove, and the other is provided with at least a first protrusion and a second protrusion, the extension directions of the first guide groove and the second guide groove are parallel to each other, and the first protrusion and the second protrusion are respectively inserted into the first guide groove and the second guide groove, so as to ensure that the tilt angle of the sliding bracket remains unchanged when it slides relative to the base.

[0012] In another embodiment, the locking assembly further includes a rotating rod and a torsion spring; the handle is hinged to the sliding bracket via the rotating rod, the axis of the rotating rod being parallel to the axis of the locking rod; the torsion spring is sleeved on the rotating rod, and one end abuts against the base, generating an elastic force that causes the locking rod to engage with the base, thereby ensuring that the locking assembly remains locked to the base.

[0013] In addition, the present invention also provides a safety seat to improve the convenience of getting in and out of a vehicle, which is achieved by the following technical solution:

[0014] It includes a seat body and the aforementioned safety seat mounting base, wherein the seat body is located above the base, and the sliding bracket is fixedly connected to the seat body.

[0015] Compared with the prior art, the safety seat of the present invention can lock the seat body to a suitable position on the base through the locking component during the driving process. When getting in and out of the vehicle, the seat can be unlocked and the sliding bracket can be slid to a position that facilitates getting in and out of the vehicle before locking it, thereby improving the usable space inside the vehicle, reducing the possibility of collisions when getting in and out of the vehicle, and because the sliding bracket is in a locked state during the process of getting in and out of the vehicle, it has high stability.

[0016] In one embodiment, a push-pull plate is further included, which is mounted on the surface of the seat body facing the child safety seat mounting base; the push-pull plate is provided with a pressure block protruding toward the locking assembly, and pulling the push-pull plate causes it to slide relative to the seat body, and the pressure block can approach the locking assembly and rotate it to improve the convenience of unlocking.

[0017] In another embodiment, a return spring is provided between the push-pull plate and the seat body. The return spring can generate an elastic force that causes the pressure block to move away from the locking assembly, so as to return to the locked state after being released.

[0018] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

[0030] Please refer to the following: Figures 1 to 3 The safety seat of the present invention includes a seat body 10 and a mounting base 20. The mounting base 20 can be installed onto a car seat (not shown) using existing fixing methods such as ISOFIX. The seat body 10 is mounted above the mounting base 20. The mounting base 20 has a frontal, rear, left, and rightward orientation, with the frontal or rearward orientation relative to the vehicle's direction of movement, and the car door located on the left or right side respectively. As needed, the seat body 10 can be locked to at least a first or second position on the mounting base 20, or the seat body 10 can be released from the first or second position, allowing the seat body 10 to slide relative to the mounting base 20 to the second or first position, thereby changing the position of the seat body 10 relative to the car, creating space for children to get in and out of 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, forming a support space. In use, a child sits on the seat plate 11 and can lean against the backrest 12. The connecting rod 13 passes through and is fixed to the side of the backrest 12 facing away from the seat plate 11. In this embodiment, two opposing mounting blocks 121 protrude from the side of the backrest 12 facing away from the seat plate 11, and the connecting rod 13 passes between the two mounting blocks 121. The connecting rod 13 is connected to the mounting seat 20 to mount the seat body 10 onto the mounting seat 20. Furthermore, the seat body 10 is not limited to being connected to the mounting base 20 via the connecting rod 13, but can also be directly fixed to the mounting base 20 by welding, screws, or other methods; the seat body 10 can also be a carrier such as an infant carrier in the prior art, and its orientation can be changed according to actual needs. For example, when a child is sitting, its orientation is forward, while when an infant is sitting, the orientation can be changed to the rear, left, or right; the surface of the seat plate 11 can be set to be parallel to the car seat surface, or have a certain tilt angle relative to the car seat surface to improve comfort.

[0032] Please refer to the following: Figure 4 and Figure 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. The locking assembly 24 is mounted on the sliding bracket 23 and is rotatable relative to it. As the locking assembly 24 rotates relative to the sliding bracket 23, it can engage with or disengage from the connecting plate 22, thereby locking the sliding bracket 23 to or unlocking it 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, which is in contact with the car seat during use. In one embodiment, the outer bottom surface 211 is parallel to the 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. (See also...) Figure 6Projecting along a direction perpendicular to the outer bottom surface 211, the number of grooves 221 is two or more. Multiple grooves 221 are disposed on the surface of the connecting plate 22 facing the seat body 10 and arranged side-by-side in a straight line. The extending direction of each groove 221 is perpendicular to its arrangement direction. The locking component 24 can sequentially engage with each groove 221 to lock the seat body 10 to the first position, the second position, etc. Further, the number of grooves 221 is three or more, to lock the seat body 10 to multiple positions, such as a third position between the first and second positions. Different grooves 221 correspond to different locking positions. In one embodiment, the connecting plate 22 and the base 21 are integrally formed, and the connecting plate 22 is fixed relative to the base 21. Depending on the age of the child riding, the arrangement direction of each groove 221 is set to a front-back or left-right direction, and the seat body 10 can slide along the arrangement direction of each groove 221 in a front-back or left-right direction. In another embodiment, the base 21 is hollow inside, with an opening (not labeled) on the side facing the seat body 10. Its inner bottom surface has a positioning post 212 protruding towards the connecting plate 22. The axis of the positioning post 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, with its middle portion protruding into the base 21 towards the outer bottom surface 211. The connecting plate 22 is embedded in the base 21, and the positioning post 212 is inserted into the middle of the connecting plate 22. The axis of the connecting plate 22 coincides with the axis of the positioning post 212, allowing the connecting plate 22 to rotate relative to the base 21 around the positioning post 212. The base 21 supports the connecting plate 22. Furthermore, the groove 221 has two or more rows, symmetrically arranged on opposite sides of the positioning post 212. In addition, the connecting plate 22 can be connected to the base 21 by means of a movable pin or the like, and locked to the base 21 as needed, so that the connecting plate 22 can switch between a rotating and a fixed state relative to the base 21. The locking of the connecting plate 22 on the base 21 can be specifically referred to the conventional settings of the prior art, which will not be described in detail here.

[0035] Please see Figure 7The fixing bracket 222 protrudes from the connecting plate 22 facing the seat body 10, and its extending direction is parallel to the arrangement direction of the grooves 221. In one embodiment, the fixing bracket 222 is integrally formed with the connecting plate 22; in another embodiment, the fixing bracket 222 is a sheet metal part, inserted into the connecting plate 22 and fixed thereto to improve strength. The fixing bracket 222 is provided with at least a first guide groove 2221 and a second guide groove 2222 extending in parallel directions. The first guide groove 2221 and the second guide groove 2222 respectively engage with the sliding bracket 23 to guide the sliding of the sliding bracket 23. The at least two guide grooves extending in parallel directions ensure that the sliding bracket 23 maintains a constant angle of inclination relative to the outer bottom surface 211 during sliding, thereby ensuring that the inclination of the seat body 10 relative to the car seat remains constant. Furthermore, projected along the extending direction of the groove 221, the extending directions of the first guide groove 2221 and the second guide groove 2222 are parallel to each other but not 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, increasing the ease of operation during sliding. Furthermore, there are two fixing brackets 222, symmetrically arranged on both sides of the positioning post 212, with the groove 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 extending direction is parallel to the extending direction 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 fix the seat body 10 to the sliding bracket 23. The locking component 24 passes through the second mounting hole 232 and can rotate about an axis. The axis of rotation of the locking component 24 is parallel to the extending 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 protrude from the side facing the fixed bracket 222 and are respectively inserted into the first guide groove 2221 and the second guide groove 2222. In one embodiment, the second mounting hole 232 is close to the outer edge of the connecting plate 22 for easy operation. Furthermore, the sliding bracket 23 is also provided with a fixing piece 236. The fixing piece 246 is fixed to the surface of the seat plate 11 facing the connecting plate 22 by screws or other means. The locking component 24 passes through the second mounting hole 232 and the fixing piece 246 in sequence and is fixed to them 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 component 24 passes 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 component 24 in 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. Furthermore, it is understood that, as needed, the first protrusion 234 and the second protrusion 235 can be modified to be set on the fixed bracket 222, and correspondingly, the first guide groove 2221 and the second guide groove 2222 can be modified to be set on the sliding bracket 23, which can also achieve the guiding effect.

[0037] Please see Figure 8The locking assembly 24 includes a handle 241, a locking lever 242, a rotating lever 243, and a torsion spring 244. The locking lever 242 and the rotating lever 243 pass through the handle 241, their axes being parallel to the extending direction of the groove 221. The rotating lever 243 is hinged to the sliding bracket 23 and close to the outer edge of the connecting plate 22. The handle 241 is hinged to the sliding bracket 23 via the rotating lever 243. The locking lever 242 is close to the interior of the connecting plate 22. The side of the handle 241 away from the locking lever 242 is a pulling part 2411. When the seat body 10 faces forward, the pulling part 2411 moves forward, and the locking lever 242 moves backward. Pulling the pulling part 2411 downward toward the connecting plate 22 causes the handle 241 to rotate around the rotating lever 243, and the locking lever 242 subsequently engages with one of the grooves 221 or disengages from one of the grooves 221. The torsion spring 244 is sleeved on the rotating rod 243, with its two ends abutting against the connecting plate 22 and the seat body 10, respectively. The elastic force of the torsion spring 244 is applied to the rotating rod 243, causing the locking rod 242 to remain in the position of facing the groove 221 when the handle 241 is not pulled, preventing the locking assembly 24 from unlocking automatically. Preferably, there are two torsion springs 244, located on opposite sides of the rotating rod 243 along its axial direction.

[0038] For further information, please refer to [link / reference]. Figure 9The 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 installed 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 surface of the push-pull plate 31 extends from the middle of the seat plate 11 to the outer edge. A pressure block 311 protruding towards the mounting seat 20 is provided on the side near the middle of the seat plate 11, and a recess 312 recessed towards the seat body 10 is provided on the side away from the middle of the seat plate 11. The pressure block 311 is located between the pull part 2411 and the rotating rod 243, and its side facing the pull part 2411 is inclined. From the seat plate 11 towards the connecting plate 22, the distance from the pressure block 311 to the pull part 2411 gradually increases. Reaching into the recess 312, pull the push-pull plate 31 away from the backrest 12. The pressure block 311 approaches the pulling part 2411 and gradually presses the pulling part 2411 against the connecting plate 22, thereby promoting the locking lever 242 to leave the groove 221, achieving unlocking. Pushing the push-pull plate 31 in the opposite direction, the pressure block 311 moves away from the pulling part 2411. Under the action of the torsion spring 244, the locking lever 242 turns towards the groove 221, achieving locking. The 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 pulling part 2411; after releasing the push-pull plate 31, under the action of the return spring 32, the pressure block 311 automatically moves away from the pulling part 2411.

[0039] Based on the above structure, the following embodiments will illustrate the position adjustment of the safety seat on the car seat.

[0040] Example 1:

[0041] In this embodiment, the slots 221 are arranged along the left-right direction of the seat body 10, the pull part 2411 is located on the side near the door, and the seat plate 11 is tilted. During vehicle operation, the locking component 24 engages with the mounting base 20, and the seat body 10 is locked on the mounting base 20. When getting in and out of the vehicle, pulling the push-pull plate 31 causes the handle 241 to rotate around the rotating rod 243, the locking rod 242 disengages from the connecting plate 22, and the seat body 10 is unlocked on the mounting base 20. Pulling the seat body 10 to the left or right moves the seat body 10 out of the door at a constant tilt angle. After releasing the push-pull plate 31, the locking rod 242 re-engages with the slot 221, and the seat body 10 returns to the locked state. Children can get in and out of the vehicle in a stable state, and because the tilt angle of the seat plate 11 remains constant during the movement of the seat body 10, the possibility of children being startled is reduced.

[0042] Example 2:

[0043] In this embodiment, the connecting plate 22 is rotatable relative to the base 21. During vehicle operation, the connecting plate 22 can be rotated so that the child faces forward, and the handle 241 turns to the forward position, locking the seat body 10. When getting in and out of the vehicle, the connecting plate 22 can be rotated first so that the child faces the door, causing the handle 241 to turn to the left or right. Then, the push-pull plate 31 is pulled, causing the handle 241 to rotate around the rotating rod 243. The locking rod 242 disengages from the connecting plate 22, and the seat body 10 is unlocked on the mounting base 20. After pulling the seat body 10 towards the door, the push-pull plate 31 is released, and the locking rod 242 re-engages in the groove 221, returning the seat body 10 to the locked state. This ensures that the seat body 10 moves close to the door and remains stably locked when the child gets in and out of the vehicle.

[0044] Compared with the prior art, the safety seat mounting base and 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 in and out of the car;

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

[0047] 3. The orientation of the seat body can be adjusted arbitrarily;

[0048] 4. The locking component can maintain the locked state when there is no external force, which provides high security.

[0049] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
