Description

Technical Field

[0001] The present invention relates to a safety seat, in particular to a safety seat with a lateral protection function and a side protection mechanism thereof. Background Art

[0002] Safety seats have become essential for children riding in cars, providing them with a safe and comfortable ride. Safety seats use restraints to secure infants and young children. In the event of emergency braking or an unexpected collision, the safety seat's shell mitigates the impact on the infant and child, while its restraints limit movement, minimizing injuries and ensuring their safety. Some safety seats have side protection blocks on both sides to provide side impact protection. Some side protection blocks are foldable to reduce the space required when the safety seat is stored. These side protection blocks typically require the user to actively open or close them, but sometimes users may forget to deploy them during use, rendering their lateral protection ineffective or significantly reducing its functionality. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to make up for the deficiencies of the existing technology, a side protection mechanism for a safety seat and a safety seat with a side protection mechanism are provided, which can use a motor to drive the side protection blocks to be folded or unfolded, making it convenient for users to operate.

[0004] According to an embodiment of the present invention, a side protection mechanism is used for a safety seat and includes a pivot seat, a side protection block and a motor. The pivot seat has a locking slot. The side protection block includes a locking block and is pivotally connected to the pivot seat. The motor is disposed on the pivot seat. The motor is connected to the side protection block to drive the side protection block to rotate relative to the pivot seat to fold or unfold. Particularly, after the side protection block rotates and unfolds, the locking block is located directly in front of the lock slot opening and outside the lock slot. Thereby, after the side protection mechanism is installed in the safety seat, the unfolded side protection block can increase the side collision prevention capability of the safety seat. By controlling the operation of the motor, the side protection block can be driven to fold or unfold, which is convenient for the user to operate and effectively solves the problem of the side protection function of the side protection block being ineffective or greatly reduced due to user negligence.

[0005] According to another embodiment of the present invention, a safety seat includes a seat body and the aforementioned side protection mechanism. The side protection mechanism's pivotal connection is disposed on a side of the seat body. After the side protection blocks rotate and deploy, they protrude outward from the seat body. Similarly, by controlling the operation of a motor, the side protection blocks can be driven to fold or deploy, providing convenient operation for the user and effectively resolving the issue of the side protection blocks being rendered ineffective or significantly reduced in their lateral protection function due to user negligence.

[0006] The advantages and spirit of the present invention can be further understood through the following detailed description of the invention and the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Please refer to Figure 1 and Figure 2 . The safety seat 1 according to an embodiment of the present invention includes a base 12, a seat body 14 and two side protection mechanisms 16. The base 12 can be placed on the back seat of a car, and the anchoring device 12a of the base 12 can be locked to the anchoring structure of the car seat. The base 12 also has support feet 12b, which can rest on the floor near the car seat and support the base 12. The seat body 14 is detachably connected to the base 12. The side protection mechanisms 16 are arranged on both sides of the seat body 14, and the side protection mechanisms 16 can be operated to provide lateral protection for the seat body 14.

[0058] Please also refer to Figure 3 In this embodiment, the side protection mechanism 16 includes a pivot seat 162, a side protection block 164 and a motor 166. The pivot seat 162 is provided on the seat body 14. The pivot seat 162 can be structurally integrated into the shell of the seat body 14, but is not limited to this in actual applications; for example, the pivot seat 162 is another structural member (relative to the seat body 14) and is simply locked to the shell of the seat body 14. The side protection block 164 is pivotally connected to the pivot seat 162, so that the side protection block 164 can be rotated relative to the rotation axis A1 (in Figure 3 The motor 166 is mounted on the pivot seat 162. The motor 166 is connected to the side protection block 164 (including direct connection and indirect connection) to drive the side protection block 164 to rotate relative to the pivot seat 162 to retract (as shown in FIG. Figure 1 shown in the collapsed state) or expanded (as shown Figure 2The expanded state shown). In actual applications, the operation of the motor 166 can be controlled by a control module (for example, implemented as a circuit board module), and the control module can be further connected to a smart phone for communication, so that the user can control the state of the side protection block 164 (for example, the aforementioned folded state or expanded state) via the smart phone. After the side protection block 164 is rotated and expanded, the side protection block 164 protrudes outward from the seat body 14, thereby providing lateral protection for the seat body 14. In addition, the safety seat 1 can be provided with an energy storage device (such as a battery) or connected to the car's power system (for example, via the car's 12V socket) to supply the power required for the operation of the electronic devices (including the motor 166 and the circuit board module) provided on the safety seat 1, which will not be elaborated separately.

[0059] Please refer to Figures 3 to 8 . In this embodiment, the motor 166 is connected to the side protection block 164 via the gear set 168. The side protection block 164 includes a housing 1642, a locking block 1644 and a connecting rod 1646. The housing 1642 is mainly formed by a combination of a front cover 1642a and a rear cover 1642b and is pivotally connected to the pivot seat 162. The locking block 1644 is movably disposed in the housing 1642. The connecting rod 1646 connects the locking block 1644 and the gear set 168. The motor 166 drives the side protection block 164 to rotate relative to the pivot seat 162 via the gear set 168, the connecting rod 1646 and the locking block 1644.

[0060] Please refer to Figure 5 、 Figure 7 and Figure 8 The gear set 168 includes a driving gear 1682, a clutch gear 1684 and a driven gear 1686. The driving gear 1682 and the clutch gear 1684 are coaxial (rotation axis A2, Figure 5 and Figure 8 Indicated by chain lines and in Figure 7 The clutch gear 1684 is engaged with the driven gear 1686. The driven gear 1686 is connected to the connecting rod 1646 so as to be able to connect the connecting rod 1646. In this embodiment, the driven gear 1686 is arranged on the rotation axis A1 (that is, the rotation axis of the driven gear 1686 coincides with the rotation axis A1), and the rotation axis A1 is parallel to the rotation axis A2, but this is not limited to the actual application. For example, the driven gear 1686 is set to deviate from the rotation axis A1, and the driven gear 1686 can still connect the connecting rod 1646; for another example, the rotation axis A1 and the rotation axis A2 may not be parallel, and the clutch gear 1684 and the driven gear 1686 are matched with suitable gear types (such as bevel gears), and the two can still effectively transmit the power.

[0061] Please refer to Figure 5 、 Figure 7 and Figure 8 . The motor 166 is meshed with the drive gear 1682 via the pinion 1662 (arranged on its rotating shaft). Thereby, the motor 166 can drive the gear set 168, and then can drive the side protection block 164 to rotate relative to the pivot seat 162 through the gear set 168. In the present embodiment, the pinion 1662 and the drive gear 1682 are both spur gears, but the actual application is not limited to this. For example, the connection between the motor 166 and the gear set 168 can also be achieved by using a bevel gear, a worm gear / worm, or other gear combinations that can cooperate and transmit with each other, which will not be elaborated further. In addition, in actual applications, the rotating shaft of the motor 166 can also be directly fixedly connected to the drive gear 1682 to directly rotate the drive gear 1682.

[0062] Please refer to Figure 8 . In addition, in this embodiment, the driving gear 1682 and the clutch gear 1684 are disengaged through the wave teeth 1682a, 1684a protruding parallel to the rotation axis A2. The driving gear 1682 and the clutch gear 1684 can disengage from each other by relative movement through the wave teeth 1682a, 1684a. The gear set 168 includes a return spring 1688, which presses against the clutch gear 1684 to enable the clutch gear 1684 to engage with the driving gear 1682. Thereby, power can be transmitted between the driving gear 1682 and the clutch gear 1684, and relative rotation of the driving gear 1682 and the clutch gear 1684 can also be allowed. In other words, the disengageable engagement between the driving gear 1682 and the clutch gear 1684 can prevent the motor 166 from being disconnected from the power of the motor 166 when the motor 166 is blocked and the side protection block 164 is interfered with. In practical applications, return spring 1688 can also be positioned on the side of drive gear 1682, pressing against drive gear 1682 to force drive gear 1682 into engagement with clutch gear 1684. This structural configuration can prevent motor 166 from stalling. Furthermore, while this embodiment provides a gear set 168 (which performs both transmission and clutch functions), the present invention is not limited thereto. Any design different from gear set 168 that achieves the desired effect is encompassed by the present invention.

[0063] Please refer to Figure 3 、 Figure 4 、 Figures 7 to 11 In this embodiment, the pivot seat 162 has a locking groove 162a and an outer surface 162b. The outer surface 162b is adjacent to the locking groove 162a. In general, the cross-sectional view of the side protection mechanism 16 after the side protection block 164 is folded is as follows: Figure 9 At this time, if the motor 166 drives the gear set 168 to rotate the driven gear 1686 clockwise, the driven gear 1686 drives the locking block 1644 via the linkage rod 1646 to rotate the locking block 1644 around the rotation axis A1, thereby unfolding the side protection block 164 (for example, Figure 9 Rotate to Figure 10 After the side protection block 164 rotates to the deployed position (eg Figure 10 and Figure 11 As shown in FIG1 , the locking block 1644 is located in front of the opening of the locking slot 162a and outside the locking slot 162a. At this time, in principle, because the side protection block 164 is connected to the motor 166, the motor 166 provides a certain degree of positioning function for the side protection block 164, which helps to keep the side protection block 164 in the deployed position. Then, when the motor 166 continues to drive the driven gear 1686 to rotate, the driven gear 1686 will drive the linkage rod 1646 to link the locking block 1644 toward the pivot seat 162 and move into the locking slot 162a (as shown in FIG1 ). Figure 4 and Figure 7 As shown), it is possible to ensure that the side protection block 164 remains in the expanded state. Figure 10 In the embodiment, when the side protection block 164 rotates to the deployed position, the pivot seat 162 can also abut against the housing 1642 (the rear cover 1642b) in actual application (e.g. Figure 10 As shown in the middle circle A, it can prevent excessive rotation when the side protection block 164 is manually operated. This can also help the side protection block 164 to stay in the deployed position.

[0064] Figure 7 The side protection block 164 is in a locked state. Afterwards, if the side protection block 164 is to be retracted, the motor 166 can be controlled to drive the side protection block 164 to move in the opposite direction via the gear set 168. Figure 7 In the embodiment, the motor 166 drives the driven gear 1686 to rotate counterclockwise via the gear set 168. The driven gear 1686 drives the locking block 1644 to move upward via the connecting rod 1646, so that the locking block 1644 is disengaged from the locking groove 162a (as shown in FIG. Figure 10 and Figure 11 status shown).

[0065] Figure 10 and Figure 11 The side protection block 164 is in the unlocked state. Then, the motor 166 continues to drive the driven gear 1686 to rotate counterclockwise via the gear set 168, and the side protection block 164 rotates together with the driven gear 1686 until the side protection block 164 is retracted (as shown in FIG. Figure 9 As previously described, the side protection block 164 can be deployed and retracted by electric power, that is, the side protection mechanism 16 can realize the deployment of the side protection block 164 by controlling the operation of the motor 166 (such as the state of the side protection block 164 is automatically Figure 9 ,through Figure 10 ,to Figure 7 Change), fold (such as the state of the side protection block 164 Figure 7 ,through Figure 10 ,to Figure 9 change).

[0066] In addition, please refer to Figure 3 、 Figure 4 、 Figures 6 to 8 In this embodiment, the linkage rod 1646 includes a rod portion 1646a and a connecting portion 1646b, wherein the connecting portion 1646b is movably disposed on the rod portion 1646a. The rod portion 1646a is connected to the driven gear 1686 and is connected to the locking block 1644 via the connecting portion 1646b. The locking block 1644 has a docking portion 1644a, and the connecting portion 1646b is detachably engaged with the docking portion 1644a. Correspondingly, the connecting portion 1646b is detached from the docking portion 1644a (refer to FIG. 1 ). Figure 12 In the state shown), the connecting rod 1646 is not connected to the locking block 1644, and the locking block 1644 can move relative to the connecting rod 1646.

[0067] Please refer to Figure 3 、 Figure 4 and Figure 7 In this embodiment, the side protection block 164 includes a pressing member 1648 (which is formed by combining two structural members) and is exposed on the surface of the housing 1642. In actual application, the locking block 1644 is located in front of the locking groove 162a and outside the locking groove 162a (such as Figure 10 and Figure 11 As shown), the user presses the pressing member 1648 to push and move the connecting portion 1646b so that the connecting portion 1646b is disengaged from the engagement of the docking portion 1644a (see FIG. Figure 12 In addition, the linkage rod 1646 includes a return spring 1646c, which is tightly pressed between the rod portion 1646a and the connecting portion 1646b, and is used to drive the connecting portion 1646b back to its original position and connect with the docking portion 1644a. Similarly, the side protection block 164 also includes a return spring 1650, which is tightly pressed between the pressing member 1648 and the housing 1642, and is used to drive the pressing member 1648 back to its original position.

[0068] In addition, please refer to Figure 4 、 Figure 7 and Figure 8 In this embodiment, the side protection block 164 includes an operating member 1652 and a return spring 1654. The operating member 1652 is connected to the locking block 1644 and exposed on the surface of the housing 1642. The operating member 1652 can move together with the locking block 1644. After the connecting portion 1646b is separated from the docking portion 1644a (see FIG. Figure 12 The user can move the locking block 1644 by moving the operating member 1652. The return spring 1654 is pressed tightly between the locking block 1644 and the housing 1642. Figure 10 and Figure 11 As shown) and the connecting portion 1646b is separated from the docking portion 1644a (see Figure 12 The return spring 1654 pushes the lock block 1644 to insert into the lock slot 162a (as shown in FIG. Figure 13 As shown, and reference Figure 4 In addition, because the operating member 1652 is exposed from the housing 1642 and moves together with the locking block 1644, the operating member 1652 also has an indicator function, indicating whether the locking block 1644 is inserted into the locking slot 162a.

[0069] Thus, the side protection block 164 can be unfolded and folded manually. For example, when the side protection block 164 is in the folded state (e.g. Figure 9 As shown), the user can directly rotate (eg, by hand) the side protection block 164 to the deployed position (eg, Figure 10 As shown). During the aforementioned rotation process, the driven gear 1686 rotates together with the side protection block 164, and the clutch gear 1684 is also driven to rotate by the driven gear 1686. However, through the clutch action between the driving gear 1682 and the clutch gear 1684 (i.e., through the disengageable meshing formed by the wave teeth 1682a and 1684a, as shown in FIG. Figure 8 As shown), the rotation of the clutch gear 1684 will not damage the motor 166. After the user rotates the side protection block 164 to the deployed position (as shown Figure 10 and Figure 11 As shown), the user can press the pressing member 1648 to disengage the connecting portion 1646b (of the linkage rod 1646) from the docking portion 1644a (of the locking block 1644) (see FIG. Figure 12 At this time, the locking block 1644 will be pushed by the return spring 1654 and inserted into the locking groove 162a, as shown Figure 13 As shown (wherein the locking block 1644 is inserted into the locking slot 162a, refer to Figure 4 ). Thus, the operation of manually unfolding the side protection block 164 is completed; wherein, the side protection block 164 is in the unfolded state, and the locking block 1644 inserted into the locking slot 162a can keep the side protection block 164 in the unfolded state. In addition, if you want to fold Figure 13 As shown in the side protection block 164 (at this time, the locking block 1644 is inserted into the locking groove 162a), the user can move the operating member 1652 to move the locking block 1644 so that the locking block 1644 is disengaged from the locking groove 162a and the connecting portion 1646b (of the linkage rod 1646) is connected to the docking portion 1644a (of the locking block 1644) under the action of the return spring 1646c, as shown in FIG. Figure 10 Afterwards, the user can manually rotate the side protection block 164 or the motor 166 can drive the side protection block 164 to rotate to the folded position (as shown). Figure 9shown).

[0070] For another example, when the side protection block 164 is in the Figure 7 In the expanded state shown in FIG. 1 (where the locking block 1644 is inserted into the locking slot 162a), the user can press the pressing member 1648 to disengage the connecting portion 1646b (of the linkage rod 1646) from the docking portion 1644a (of the locking block 1644) (as shown in FIG. 1 ). Figure 12 As shown), and at the same time, the operating member 1652 is moved to move the locking block 1644 so that the locking block 1644 is disengaged from the locking groove 162a, as shown Figure 14 Then, the user can rotate the side protection block 164 to the folded position (as shown in FIG. Figure 15 As shown). Thus, the operation of manually retracting the side protection block 164 is completed. Figure 15 In the side protection block 164 shown, although the locking block 1644 and the linkage rod 1646 are not connected together, the motor 166 can still drive the linkage rod 1646 and the housing 1642 (or drive the side protection block 164) to rotate via the gear set 168. The side protection block 164 rotates to the extended position so that the locking block 1644 is located in front of the opening of the lock slot 162a and outside the lock slot 162a (as shown in FIG. Figure 14 As shown in the state), the locking block 1644 is inserted into the locking groove 162a under the push of the return spring 1654, as shown in the state shown in the state. Figure 7 wherein, in principle, when the locking block 1644 is inserted into the locking slot 162a, the connecting portion 1646b of the linkage rod 1646 is again connected to the docking portion 1644a of the locking block 1644. Therefore, the manually folded side protection block 164 will not interfere with the deployment of the electrically driven side protection block 164.

[0071] In addition, please refer to Figure 5 、 Figure 6 and Figure 8 In this embodiment, the side protection block 164 includes a torsion spring 1656 connecting the pivot seat 162 and the housing 1642. The torsion spring 1656 drives the side protection block 164 to rotate toward the retracted position, helping to maintain the side protection block 164 in the retracted position for easy storage.

[0072] As previously explained, the side protection blocks 164 of the side protection mechanism 16 can be deployed and retracted manually or electrically (via motor 166). Furthermore, both manual and electric actuation modes can be used interchangeably for deployment and retraction (e.g., manually deploying the side protection blocks 164 and then electrically retracting them; or, alternatively, electrically deploying the side protection blocks 164 and then manually retracting them) without interfering with each other. Therefore, the side protection mechanism 16 offers significant operational flexibility and ease of operation, effectively preventing the side protection function of the side protection blocks 164 from being lost or significantly reduced due to user negligence. Furthermore, the locking block 1644 of the side protection block 164 is detachably connected to the linkage rod 1646. After the locking block 1644 is detached from the linkage rod 1646, the structural interference between the side protection block 164 and the gear set 168 is reduced, and the rotation of the side protection block 164 relative to the pivot seat 162 is less affected by the gear set 168. This helps reduce the force required to manually rotate the side protection block 164 and also helps reduce the structural strength requirements of the components of the side protection mechanism 16.

[0073] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
