Description

Technical Field

[0001] This invention relates to a safety seat, and more particularly to a safety seat with lateral protection function and its lateral protection mechanism. Background Technology

[0002] Child safety seats have become essential for children traveling in cars, providing a safe and comfortable riding space. A child safety seat is a device that restrains infants and toddlers using restraint mechanisms. In the event of emergency braking or a collision, the safety seat uses its shell to cushion the impact on the infant or toddler and its restraint mechanisms to restrict the infant's body movement, thereby reducing injury and ensuring the infant's safety during the accident. Some child safety seats have side impact protection blocks on both sides to provide side impact protection. Some side impact protection blocks are designed to be foldable to reduce the space occupied when the safety seat is stored. These types of side impact protection blocks usually require the user to actively open or close them, but sometimes users may forget to unfold the side impact protection blocks, causing the side protection function to fail or be significantly reduced. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a side protection mechanism for a safety seat and a safety seat with a side protection mechanism in order to overcome the shortcomings of the prior art. The side protection block can be retracted or unfolded by a motor, which is convenient for the user to operate.

[0004] According to an embodiment of the present invention, a side protection mechanism for a child safety seat includes a pivot seat, a side protection block, and a motor. The pivot seat has a locking groove. 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 retract or extend. When the side protection block is rotated and extended, the locking block is located directly in front of the locking groove opening and outside the locking groove. Therefore, after the side protection mechanism is installed on the child safety seat, the extended side protection block increases the side impact protection capability of the child safety seat. By controlling the operation of the motor, the side protection block can be driven to retract or extend, facilitating user operation and effectively solving the problem of the side protection function of the side protection block failing or being significantly reduced due to user negligence.

[0005] According to another embodiment of the present invention, the safety seat includes a seat body and a side protection mechanism as described above. A pivot seat for the side protection mechanism is disposed on one side of the seat body. When the side protection block is rotated and unfolded, it protrudes outward from the seat body. Similarly, by controlling the operation of a motor, the side protection block can be driven to retract or unfold, facilitating user operation and effectively solving the problem of the side protection function of the side protection block failing or being significantly reduced 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. Attached Figure Description

[0056] A1, A2: Rotation axis Detailed Implementation

[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 rear seat of a vehicle, and the anchoring device 12a of the base 12 can be locked to the anchoring structure of the vehicle seat. The base 12 also has support feet 12b, which can rest against the floor near the vehicle seat and support the base 12. The seat body 14 is detachably connected to the base 12. The side protection mechanisms 16 are disposed 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 disposed on the seat body 14. The pivot seat 162 can be structurally integrated into the housing of the seat body 14, but this is not a limitation in practical applications; for example, the pivot seat 162 may be a separate structural component (relative to the seat body 14) simply locked to the housing of the seat body 14. The side protection block 164 is pivotally connected to the pivot seat 162, such that the side protection block 164 can rotate relative to the rotation axis A1 (in... Figure 3 (Indicated by a chain line) Rotation. Motor 166 is mounted on pivot 162. Motor 166 is connected to side protection block 164 to drive side protection block 164 to rotate relative to pivot 162 to retract (e.g., ...). Figure 1 (as shown in the closed state) or unfolded state (e.g.) Figure 2(The image shows the unfolded state). In practical applications, the operation of the motor 166 can be controlled via a control module (e.g., a circuit board module). The control module can then communicate with a smartphone, allowing the user to control the state of the side protection block 164 (e.g., the aforementioned folded or unfolded state) via their smartphone. After the side protection block 164 is rotated and unfolded, it protrudes outward from the seat body 14, thus providing lateral protection to the seat body 14. Additionally, the safety seat 1 can be equipped with an energy storage device (e.g., a battery) or connected to the vehicle's electrical system (e.g., via a 12V outlet) to supply the power required for the operation of the electronic devices (including the motor 166 and circuit board module) mounted on the safety seat 1, which will not be elaborated further.

[0059] Please refer to Figures 3 to 8 In this embodiment, the motor 166 is connected to the side protection block 164 via a 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 within 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 drive gear 1682, a clutch gear 1684, and a driven gear 1686. The drive gear 1682 and the clutch gear 1684 are coaxial (rotation axis A2). Figure 5 and Figure 8 The middle is represented by a chain and in Figure 7 The clutch gear 1684 is set in a crosshair and is disengaged axially (i.e., along the rotation axis A2). The driven gear 1686 meshes with the driven gear 1686. The driven gear 1686 is connected to the connecting rod 1646 so as to drive the connecting rod 1646. In this embodiment, the driven gear 1686 is set on the rotation axis A1 (i.e., 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 a limitation in practical applications. For example, if the driven gear 1686 is set off from the rotation axis A1, the driven gear 1686 can still drive the connecting rod 1646; or, for example, the rotation axis A1 and the rotation axis A2 may not be parallel, and the clutch gear 1684 and the driven gear 1686 can be matched with a suitable gear type (e.g., bevel gear), and effective transmission can still be achieved between them.

[0061] Please refer to Figure 5 , Figure 7 and Figure 8 The motor 166 meshes with the drive gear 1682 via a pinion 1662 (set on its shaft). This allows the motor 166 to drive the gear set 168, which in turn drives the side protection block 164 to rotate relative to the pivot seat 162. In this embodiment, both the pinion 1662 and the drive gear 1682 are spur gears, but this is not a limitation in practical applications. For example, the connection between the motor 166 and the gear set 168 can also be achieved using bevel gears, worm gears / worm shafts, or other gear combinations that can mesh and transmit power, which will not be elaborated further. Furthermore, in practical applications, the 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 Furthermore, in this embodiment, the drive gear 1682 and the clutch gear 1684 are disengaged via wave-shaped teeth 1682a and 1684a protruding parallel to the rotation axis A2. The drive gear 1682 and the clutch gear 1684 can disengage from each other by relative movement through the wave-shaped teeth 1682a and 1684a. The gear set 168 includes a return spring 1688 that abuts against the clutch gear 1684 to engage the clutch gear 1684 with the drive gear 1682. This allows power to be transmitted between the drive gear 1682 and the clutch gear 1684, and also allows them to rotate relative to each other. In other words, the disengageable engagement of the drive gear 1682 and the clutch gear 1684 prevents the motor 166 from stalling and disconnects power from the motor 166 when the side protection block 164 is interfered with. In practical applications, the return spring 1688 can also be repositioned on the drive gear 1682 side, pressing against the drive gear 1682 to drive the drive gear 1682 to mesh with the clutch gear 1684; this configuration can prevent the motor 166 from stalling. Furthermore, although this embodiment provides a design for a gear set 168 (which serves both transmission and clutch functions), the present invention is not limited thereto. Any design different from the gear set 168 that achieves the effects of the present invention is included within the scope of this 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. Under normal circumstances, the cross-sectional view of the side protection mechanism 16 after the side protection block 164 is retracted is shown below. Figure 9 As shown. At this time, if the motor 166 drives the gear set 168 to rotate the driven gear 1686 clockwise, the driven gear 1686, via the connecting rod 1646, actuates the locking block 1644 to rotate the locking block 1644 around the rotation axis A1, thereby unfolding the side protection block 164 (e.g., from...). Figure 9 Rotate to Figure 10 After the side protective block 164 is rotated to the unfolded position (e.g.) Figure 10 and Figure 11 As shown), the locking block 1644 is located directly in front of and outside the opening of the locking groove 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, helping to keep the side protection block 164 in the unfolded position. Then, when the motor 166 continues to drive the driven gear 1686 to rotate, the driven gear 1686 will drive the connecting rod 1646 to move the locking block 1644 towards the pivot seat 162 into the locking groove 162a (as shown). Figure 4 and Figure 7 As shown), this further ensures that the side protection block 164 remains in the deployed state. Additionally, in Figure 10 In the middle, corresponding to the side protective block 164 rotating to the unfolded position, the pivot seat 162 can also abut against the housing 1642 (the rear cover 1642b) in practical applications (e.g.) Figure 10 As shown in circle A, when manually operating the side protection block 164, it can prevent excessive rotation, which also helps the side protection block 164 to stay in the unfolded position.

[0064] Figure 7 The side protection block 164 shown is in a locked state. Later, if it is desired to retract the side protection block 164, the motor 166 can be controlled to drive the side protection block 164 to move in the opposite direction via the gear set 168. Specifically, in... Figure 7 In the process, motor 166 drives driven gear 1686 to rotate counterclockwise via gear set 168. Driven gear 1686 drives locking block 1644 to move upward via connecting rod 1646, so that locking block 1644 disengages from locking groove 162a (e.g., Figure 10 and Figure 11 (As shown in the diagram). In practical applications, the connection relationship or structural interference relationship between the driven gear 1686, the connecting rod 1646, the locking block 1644, and the housing 1642 can be designed to prevent the locking block 1644 from being driven upward by the driven gear 1686. For example, in practical applications, the housing 1642 (front cover 1642a) may cause structural interference with the connecting rod 1646 (such as...). Figure 10 (As shown in circle B), causing the locking block 1644 to stop moving upwards. Alternatively, in practical applications, the housing 1642 may cause structural interference with the locking block 1644 (e.g., ...). Figure 10 As shown in circle C, the locking block 1644 stops moving upward because it moves upward and comes into contact with the back cover 1642b.

[0065] Figure 10 and Figure 11The side protection block 164 shown is in the unlocked state. Next, 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 retracts (as shown). Figure 9 As shown above, the unfolding and retraction of the side protection block 164 can be electrically driven, that is, the side protection mechanism 16 can achieve the unfolding of the side protection block 164 by controlling the operation of the motor 166 (such as the side protection block 164 being in a state of...). Figure 9 ,through Figure 10 ,to Figure 7 Changes), retraction (such as the state of side protection block 164 from...) 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 1646 includes a rod portion 1646a and a connecting portion 1646b, with the connecting portion 1646b movably disposed on the rod portion 1646a. The rod portion 1646a is connected to the driven gear 1686 and to the locking block 1644 via the connecting portion 1646b. The locking block 1644 has a mating portion 1644a, and the connecting portion 1646b is detachably connected to the mating portion 1644a. (See reference...) Figure 12 (As shown in the diagram), the linkage 1646 and the locking block 1644 are not connected, and the locking block 1644 can move relative to the linkage 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) exposed on the surface of the housing 1642. In practical applications, this corresponds to the locking block 1644 being located directly in front of and outside the locking groove 162a (e.g., Figure 10 and Figure 11 As shown), the user presses the pressing member 1648 to push and move the connecting part 1646b, so that the connecting part 1646b disengages from the mating part 1644a (see reference). Figure 12 The engagement is shown in the diagram. Furthermore, the linkage 1646 includes a return spring 1646c, which abuts against the rod portion 1646a and the connecting portion 1646b to drive the connecting portion 1646b back to its original position and connect it with the mating portion 1644a. Similarly, the side protection block 164 also includes a return spring 1650, which abuts against the pressing member 1648 and the housing 1642 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 protrudes from the surface of the housing 1642. The operating member 1652 can move together with the locking block 1644. After the connecting part 1646b disengages from the docking part 1644a (see reference 1644a), the operating member 1652 moves with the locking block 1644. Figure 12 (As shown in the diagram), the user can move the locking block 1644 by moving the operating element 1652. The return spring 1654 is pressed against the locking block 1644 and the housing 1642. The locking block 1644 is aligned with the locking groove 162a (as shown in the diagram). Figure 10 and Figure 11 (As shown) and the connecting part 1646b disengages from the docking part 1644a (see reference). Figure 12 (as shown in the diagram), the return spring 1654 pushes the locking block 1644 to insert into the locking groove 162a (as shown in the diagram). Figure 13 As shown, and refer to Figure 4 (The state shown is where the locking block 1644 is inserted into the locking groove 162a). In addition, since the operating member 1652 is exposed outside the housing 1642 and moves together with the locking block 1644, the operating member 1652 also has an indicating function, indicating whether the locking block 1644 is inserted into the locking groove 162a.

[0069] Therefore, the unfolding and retraction of the side protection block 164 can also be achieved manually. For example, when the side protection block 164 is in the retracted state (such as... Figure 9 As shown), the user can directly rotate (e.g., by hand) the side protective block 164 to the unfolded position (as shown). Figure 10 (As shown). During the aforementioned rotation process, although 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, the engagement between the driving gear 1682 and the clutch gear 1684 (i.e., the disengageable meshing formed by the wave teeth 1682a and 1684a, as shown) allows for disengagement. Figure 8 As shown), the rotation of the clutch gear 1684 will not damage the motor 166. After the user rotates the protective block 164 to the unfolded position (as shown), Figure 10 and Figure 11 As shown), the user can press the pressing member 1648 to disengage the connecting part 1646b (of the linkage 1646) from the mating part 1644a (of the locking block 1644) (see reference). Figure 12 (as shown in the diagram); at this time, the locking block 1644 will be pushed by the reset spring 1654 and inserted into the locking groove 162a, as shown in the diagram. Figure 13 As shown (where lock block 1644 is inserted into lock groove 162a, see reference). Figure 4This completes the manual unfolding of the side protection block 164; wherein, the side protection block 164 is in the unfolded state, and the locking block 1644 inserted into the locking slot 162a keeps the side protection block 164 in the unfolded state. Furthermore, if it is desired to retract... Figure 13 The side protective block 164 shown (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 disengages from the locking groove 162a and the connecting part 1646b (of the linkage 1646) connects with the mating part 1644a (of the locking block 1644) under the action of the return spring 1646c. Figure 10 As shown. Afterwards, the user can manually rotate the side protection block 164 or have the side protection block 164 rotated to the folded position by the motor 166 (as shown). Figure 9 (As shown).

[0070] For example, when the side protection block 164 is in such a state Figure 7 In the unfolded state shown (where the locking block 1644 is inserted into the locking groove 162a), the user can press the pressing member 1648 to disengage the connecting part 1646b (of the linkage 1646) from the mating part 1644a (of the locking block 1644). Figure 12 As shown), and simultaneously move the operating member 1652 to move the locking block 1644, so that the locking block 1644 disengages from the locking groove 162a, as shown. Figure 14 As shown. Next, the user can rotate the side protective block 164 to the folded position (as shown). Figure 15 (As shown). This completes the manual retraction of the side protection block 164. Additionally, in Figure 15 In the side protection block 164 shown, although the locking block 1644 and the connecting rod 1646 are not connected together, the motor 166 can still drive the connecting 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 unfolded position so that the locking block 1644 is located directly in front of the opening of the locking groove 162a and outside the locking groove 162a (e.g., Figure 14 (As shown in the diagram), the locking block 1644 is inserted into the locking groove 162a under the push of the return spring 1654, as... Figure 7 As shown; in principle, when the locking block 1644 is inserted into the locking groove 162a, the connecting part 1646b of the linkage rod 1646 is connected again to the docking part 1644a of the locking block 1644. Therefore, the manually retractable side protection block 164 will not interfere with the deployment of the electrically driven side protection block 164.

[0071] Additionally, please refer to Figure 5 , Figure 6 and Figure 8In this embodiment, the side protection block 164 includes a torsion spring 1656, a connecting pivot 162, and a housing 1642. The torsion spring 1656 drives the side protection block 164 to a retracted position, which helps to keep the side protection block 164 in the retracted position for easy storage.

[0072] As previously explained, the unfolding and retraction of the side protection block 164 of the side protection mechanism 16 can be achieved manually or electrically (powered by the motor 166). Manual and electric drives can be used interchangeably in the unfolding and retraction operations (e.g., manually unfolding the side protection block 164 and then electrically retracting it; or electrically unfolding the side protection block 164 and then manually retracting it), without mutual interference. Therefore, the side protection mechanism 16 offers high operational flexibility, is convenient for users, and effectively solves the problem of lateral protection function failure or significant reduction due to user negligence. Furthermore, the locking block 1644 of the side protection block 164 and the linkage rod 1646 are connected in a detachable manner. After the locking block 1644 is disengaged from the linkage rod 1646, the structural interference between the side protection block 164 and the gear set 168 is reduced, and the influence of the gear set 168 on the rotation of the side protection block 164 relative to the pivot seat 162 is reduced. This helps to reduce the force required to manually rotate the side protection block 164 and also helps to reduce the structural strength requirements of the side protection mechanism 16.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
