Exactly, various modifications can be made to these details within the scope of equivalent schemes of the claims without departing from the present invention.

[0009] Directional descriptions such as "front", "rear", "upper", "lower", etc. in this specification are for convenience of understanding, and the present invention is not limited to these directions and can be adjusted according to the actual situation.

[0010] First, the vehicle device of the present application will be described with reference to FIGS. 1A to 2. FIG. 1A is a perspective view of an embodiment of the vehicle device of the present application, where the riding part 300 is a child seat. FIG. 1B is a perspective view of another embodiment of the vehicle device of the present application, where the riding part 300 is a carrycot. FIG. 2 is a perspective view showing the relationship between the base 400, the crossbars (front crossbar 310, rear crossbar 320), and the engaging hook structure 100 of the vehicle device.

[0011] As shown in the figure, the vehicle device is divided into a base 400 and a riding part 300, where the riding part 300 may be a seat or a carrycot. The riding part 300 may be provided to be joined to the base 400 in the longitudinal direction (i.e., the traveling direction of the vehicle), for example, in the joining manner shown in FIG. 1A. At this time, the child in the riding part 300 faces substantially in the traveling direction of the vehicle. The riding part 300 may be provided to be joined to the base 400 in the lateral direction, for example, in the joining manner shown in FIG. 1B. At this time, the child in the riding part 300 lies on the carrycot, and his / her body is substantially horizontal in the traveling direction of the vehicle.

[0012] The riding part 300 may be joined to the base 400 or may be removable from the base 400. The joining between the two is realized by the crossbars (front crossbar 310, rear crossbar 320) and the engaging hook structure 100. In the embodiment shown in FIG. 2, the crossbars are attached to the bottom of the riding part 300 (the riding part is not shown), and the engaging hook structure is attached to the base 400. The engaging hooks in the engaging hook structure 100 can hook or release the crossbars to engage or disengage the riding part 300 from the base 400. In other embodiments, the crossbars may be attached to the base 400, and the engaging hook structure 100 may be attached to the riding part 300. In the embodiment shown in FIG. 2, two engaging hook structures 100 are provided along the extending direction of the crossbar. In other embodiments, the engaging hook structure 100 may be set to be single or two or more along the extending direction of the crossbar.

[0013] The crossbars are provided in two parallel rows along the traveling direction of the vehicle, and are respectively called a front crossbar 320 and a rear crossbar 310. In the present application, the engagement hook structures for joining the front crossbar 320 and the rear crossbar 310 have different structures. Hereinafter, the "engagement hook structure" particularly refers to an engagement hook structure 100 for engaging the rear crossbar 310 (i.e., the rear engagement hook structure). For the sake of distinction, the engagement hook structure for engaging the front crossbar 320 is called a "front engagement hook structure 200".

[0014] Next, referring to FIGS. 3A to 3D, the specific structure of the engagement hook structure 100 and the joining method with the rear crossbar 310 are shown. FIG. 3A is a perspective view showing the relationship among the base 400 of the vehicle device, the rear crossbar 310, and the engagement hook structure 100. Here, the upper housing is removed to show the specific structure inside the housing. FIG. 3B is an enlarged view of the engagement hook structure 100 in FIG. 3A. FIG. 3C is a perspective view showing the relationship among the base 400 of the vehicle device, the rear crossbar 310, and the engagement hook structure 100 from another angle. Here, the upper housing is removed to show the specific structure inside the housing. FIG. 3D is an enlarged view of the engagement hook structure 100 in FIG. 3C.

[0015] As shown in the figure, the engagement hook structure 100 includes a bracket 120, an engagement hook 110, a locking member 140, and a slider 130, and also includes an engagement hook pivot 151, a pin 152, a first elastic member 153, and a second elastic member 154. The bracket 120 is fixed to the base 400 for attaching other members of the engagement hook structure 100. The engagement hook 110 is pivotally attached to the bracket 120 to provide a locking function of the engagement hook structure 100. The locking member 140 is also pivotally attached to the bracket 120 and serves to lock the engagement hook 110 in the unlocked position. The engagement hook pivot 151 is installed on the bracket 120 to provide a pivoting function of the engagement hook 110. The pin 152 is inserted through the engagement hook 110 along the extending direction of the rear crossbar 310. The first elastic member 153 is provided between the bracket 120 and the engagement hook 110 to press the engagement hook 110 to the locked position or the unlocked position. The second elastic member 154 is provided between the bracket 120 and the locking member 140 to press the locking member 140 to the locked position. These components will be described in detail below.

[0016] FIG. 4 is a side view of the bracket 120 in the engagement hook structure 100. The bracket 120 has two side walls with substantially the same shape and facing each other. In the illustrated embodiment, the side walls are substantially rectangular, but in other embodiments, the side walls can have different joining outer shapes. At the upper edge of the side walls, there are arc-shaped recesses 121 for receiving the cross bar. When the cross bar is positioned in the recess 121 of the side wall and the engagement hook 110 hooks the cross bar, the cross bar is stably joined to the engagement hook structure 100. On the side walls, there are provided engagement hook pivot mounting holes 123 and locking member pivot mounting holes 124 so that the engagement hook pivot 151 and the engagement hook pivot (not shown) are installed between the two side walls. At the lower part of each side wall, there is a bracket fixing part 127, which is a long through hole in this embodiment. On one side of each side wall (the left side of the side wall in FIG. 4), there is a first elastic member fixing part 125 provided as a depression at the edge of the side wall, and one end of the first elastic member 153 is fixed in this depression. That is, the first elastic member 153 is fixed to at least one side wall of the bracket 120. On one side of each side wall (the left side of the side wall in FIG. 4), there is a slider accommodating part 122 provided as a rectangular opening, and one end of the slider 130 can be inserted into the slider accommodating part 122 and positioned and limited by the slider 130. On the other side of each side wall (the right side of the side wall in FIG. 4), there is provided a pin relief part 126 so that the pin 152 is not interfered with the side wall of the bracket 120 as the engagement hook 110 rotates.

[0017] FIG. 5 is a side view of the engagement hook 110 in the engagement hook structure 100. In this embodiment, one end of the engagement hook 110 is a protruding first hook portion 111, and the other end is a protruding foot portion 117. An engagement hook pivot hole is provided at the central portion of the engagement hook 110 so that the engagement hook pivot 151 can be inserted therethrough. A joint portion 118 (elastic member joint portion) is provided between the first hook portion 111 and the engagement hook pivot hole 114, and the other end of the first elastic member 153 is fixed to this joint portion 118. The engagement hook 110 further has a second hook portion 112 located between the engagement hook pivot 151 and the first hook portion 111. The first hook portion 111 and the second hook portion 112 have the same axial position with respect to the engagement hook pivot 151, extend forward longer than the first hook portion 111, and form a substantially C-shaped accommodating portion 113 (crossbar accommodating portion) for receiving the crossbar with the first hook portion 111. Since an engagement hook abutting portion 116 extending in the thickness direction of the engagement hook 110 (that is, the axial direction of the engagement hook pivot 151) is formed at the central portion of the engagement hook 110, the first hook portion 111, the second hook portion 112, the foot portion 117, and the joint portion 118 are at different axial positions. The engagement hook abutting portion 116 is formed to have an abutting surface facing forward. In this embodiment, a pin hole 115 is formed in the joint portion 118, a pin 152 is inserted into the pin hole 115, and the other end of the first elastic member 153 (that is, the opposite end of one end of the first elastic member fixing portion 125 fixed to the bracket 120) is fixed to the pin 152, whereby the first elastic member 153 is fixed to the engagement hook 110. In other embodiments, the other end of the first elastic member 153 can also be fixed to the joint portion 118 by other methods.

[0018] FIG. 6 is a side view of the locking member 140 in the engagement hook structure 100. The locking member 140 has a pivot end 142 and a free end 143. Here, the pivot end 142 is pivotally connected to the bracket 120 via a locking member pivot axis (not shown) in a locking member pivot hole 141 parallel to the engagement hook pivot 151. The free end 143 of the locking member 140 is rotatable around the pivot end 142. A locking member abutting portion 144 formed as an abutting surface on the side of the locking member 140 is provided at the free end 143. When the locking member 140 pivots to its locking position (detailed below), the abutting surface at the locking member abutting portion 144 of the locking member 140 abuts against the abutting surface at the engagement hook abutting portion 116 of the engagement hook 110, thereby locking the engagement hook 110 in the unlocked position.

[0019] The first elastic member 153 is provided to always apply a tensile force to the engagement hook 110. In this embodiment, the first elastic member 153 is a tension spring. In other embodiments, the first elastic member 153 may be other elastic members capable of applying a tensile force.

[0020] The second elastic member 154 is provided to press the locking member 140 to the locking position. In this embodiment, the second elastic member 154 is a torsion spring provided on the locking member pivot. One end thereof abuts against the bracket 120, and the other end abuts against the locking member 140. In other embodiments, the second elastic member 154 may be an elastic member in other forms.

[0021] The slider 130 is arranged to slide along the base 400. One end of the slider 130 protrudes from the drag portion 131, and the other end is connected to the operating member 156. This drag portion 131 enters between the two side walls of the bracket 120, and the operating member 156 is formed as a lateral handle with respect to the slider 130. The user can contact the operating member 156 from outside the base 400 to pull the slider 130. The drag portion 131 is connected to the foot portion 117 of the engaging hook 110 in a slidable groove or a similar manner so that when the slider 130 moves forward, the engaging hook 110 can be rotated toward the unlocking position.

[0022] Hereinafter, the operation process of the engaging hook 110 of the present application will be described with reference to FIGS. 7A to 8B. FIG. 7A is a side view of the engaging hook structure 100 in the locked state. FIG. 7B is an enlarged view of the engaging hook structure 100 in FIG. 7A, where the first elastic member 153 is located on one side of the pivot axis of the engaging hook 110. FIG. 8A is a side view of the engaging hook structure 100 in the unlocked state. FIG. 8B is an enlarged view of the engaging hook structure 100 in FIG. 8A, where the first elastic member 153 is located on the other side of the pivot axis of the engaging hook 110.

[0023] In the locked state shown in FIGS. 7A to 7B, the engaging hook 110 is in the locked position, hooking the rear crossbar 310 and locking the rear crossbar 310 between the engaging hook 110 and the bracket 120. Since the first elastic member 153 is connected between the first elastic member fixing portion 125 of the bracket 120 and the joint portion 118 of the engaging hook 110, as the engaging hook 110 rotates around its pivot axis, the first elastic member 153 also changes its position accordingly and can be located on both sides of the pivot axis. When the first elastic member 153 approaches or reaches the locked position and pivots, it is located on the side closer to the crossbar of the pivot axis. In this way, the force that the first elastic member 153 exerts to pull the engaging hook 110 towards the bracket 120 rotates the engaging hook 110 towards its locked position, that is, realizes automatic locking. As shown in the figure, the pivot axis of the engaging hook 110 is the axis of the engaging hook pivot 151.

[0024] At this time, the locking member 140 is in its non-locking position, and the locking member contact portion 144 is not in contact with the engaging hook contact portion 116. The second elastic member 154 located between the locking member 140 and the bracket 120 tends to press the locking member 140 towards the locking position, but the crossbar is pressed against the free end 143 of the locking member 140 at this time, preventing the locking member 140 from rotating to the locking position.

[0025] To move the engaging hook structure 100 to the unlocked position shown in FIGS. 8A to 8B, the user pulls the slider 130 forward, specifically, pulls the operating member 156 connected to the slider 130, whereby the slider 130 rotates the engaging hook 110 towards the unlocked position. In this process, the position of the first elastic member 153 changes, moving from the side closer to the crossbar of the pivot axis of the engaging hook 110 across the pivot axis to the side farther from the crossbar, that is, passing through the "dead point" of the engaging hook 110. After passing through the dead point, the pressing force of the first elastic member 153 that attracts the engaging hook 110 towards the bracket 120 rotates the engaging hook 110 towards its unlocked position, that is, realizes automatic unlocking.

[0026] After the engagement hook 110 reaches its unlocked position, the crossbar becomes unlocked from the engagement hook structure 100, and at this time, the user can remove the vehicle device from the base 400, and the crossbar is also removed. As a result, the locking member 140 rotates to its locking position by the pressing of the second elastic member 154 without receiving the pressure of the crossbar. At this time, the locking member contact portion 144 of the locking member 140 contacts the engagement hook contact portion 116 of the engagement hook 110, preventing the engagement hook 110 from returning to the locked position, thereby preventing accidental locking of the engagement hook 110. At this time, the second hook portion 112 of the engagement hook 110 and the free end 143 of the locking member 140 are both at least partially located in the recess 121 of the bracket 120.

[0027] To return the engagement hook structure 100 from the unlocked position shown in FIGS. 8A to 8B to the locked position shown in FIGS. 7A to 7B again, the user pushes the vehicle device into the recess 121 of the bracket 120, that is, the crossbar. At this time, the crossbar presses down the second hook portion 112 of the engagement hook 110 and the free end 143 of the locking member 140, causing the engagement hook 110 to return to the locked position and the locking member 140 to return to the unlocked position.

[0028] In one embodiment, the engagement hook pivot 151 may be provided with a third elastic member 155 in the form of a torsion spring that presses the engagement hook 110 to the unlocked position, for example. Referring to FIG. 12, the third elastic member 155 provided on the engagement hook pivot 151 is shown here.

[0029] Next, referring to FIGS. 9A to 9B, the front engagement hook structure 200 of the present application will be described. FIG. 9A is a side view of the engagement hook structure 100 and the front engagement hook structure 200 of the present application in a locked state, where the front engagement hook structure 200 is shown in a cross-sectional view. FIG. 9B is an enlarged view of the front engagement hook structure 200 in FIG. 9A. Since the front engagement hook structure 200 is substantially the same as the engagement hook structure 100, only the differences between the two will be described below.

[0030] The front engaging hook structure 200 has a front engaging hook 210, a front bracket 220, and a fourth elastic member 253 (see FIGS. 7A and 8A) provided between the front engaging hook 210 and the front bracket 220. The fourth elastic member 253 does not press the engaging hook 110 to the locking position or the unlocking position as the first elastic member 153 provided between the engaging hook 110 and the bracket 120 does along with the rotation of the engaging hook 110, and the fourth elastic member 253 always presses the front engaging hook 210 to the unlocking position. In this embodiment, the fourth elastic member 253 is a torsion spring provided on the pivot axis of the front engaging hook 210. In other embodiments, the fourth elastic member 253 may be provided as an elastic member in other forms.

[0031] Hereinafter, with reference to FIGS. 10A to 11D, the operation of the vehicle device according to the present application will be described.

[0032] FIG. 10A is a side view of the engaging hook structure 100 and the front engaging hook structure 200 of the present application in a state where a slight collision causes the slider 130 to be displaced. Here, the front engaging hook structure 200 is shown in a cross-sectional view. FIG. 10B is an enlarged view of the front engaging hook structure 200 in FIG. 10A, and FIG. 10C is a partial enlarged view of FIG. 10A. Here, a part of the base 400 is removed to more clearly show other components. FIG. 10D is a partial enlarged view of FIG. 10C, and a part of the base 400 and a side wall of the bracket 120 are removed to more clearly show other components.

[0033] When a collision force is received, the passenger compartment 300 tends to move forward. If it is a seat, it will tilt forward, and if it is a calico, it will invert forward. Therefore, the front engaging hook receives a downward pressure, while the rear engaging hook does not receive pressure.

[0034] When receiving a collision force, the slider 130 slides forward. However, since the front engagement hook 210 is held by the crossbar, the front engagement hook 210 does not rotate toward its unlocking position, and the slider 130 is prevented from being completely disengaged from the front engagement hook 210. Also, since the first elastic member 153 in the rear engagement hook structure 100 tends to press the engagement hook 110 to the locked position, the rear engagement hook is always in the locked state, preventing the rear crossbar 310 from detaching.

[0035] In this way, even if the vehicle device receives a certain collision, the passenger compartment 300 does not detach from the base 400, and the safety of the children in the passenger compartment 300 is guaranteed.

[0036] FIG. 11A is a side view of the engagement hook structure 100 and the front engagement hook structure 200 of the present application in the unlocked state, where the front engagement hook structure 200 is shown in cross-section. FIG. 11B is an enlarged view of the front engagement hook structure 200 in FIG. 11A, and FIG. 11C is a partial enlarged view of FIG. 11A, where a part of the base 400 is removed to more clearly show other components. FIG. 11D is a partial enlarged view of FIG. 11A, where a part of the base 400 and one side wall of the bracket 120 are removed to more clearly show other components.

[0037] In the unlocked state, as described above, the first elastic member 153 in the rear engagement hook structure presses the engagement hook 110 to the unlocked position, and the locking member 140 locks the engagement hook 110 to the unlocked position, preventing accidental locking of the engagement hook 110. Similarly, the fourth elastic member 253 of the front engagement hook structure 200 presses the front engagement hook 210 to the unlocked position, and the front locking member 140 (not shown) locks the front engagement hook 210 to the unlocked position, preventing accidental locking of the front engagement hook 210. In this way, as long as the user does not push the crossbar into the engagement hook structure 100 and the front engagement hook structure 200 while attaching the vehicle device to the base 400, the engagement hook structure 100 and the front engagement hook structure 200 do not accidentally switch to the locked state.

[0038] In one embodiment, the first elastic member 153 is a tension spring and is fixed to at least one side wall 120 of the bracket.

[0039] In one embodiment, the two side walls of the bracket 120 are provided symmetrically with respect to each other, and each side wall has a recess 121 opening toward the upper surface at the top, which is used for arranging the cross bar.

[0040] In one embodiment, the engagement hook structure 100 further has a locking member 140 and a second elastic member 154. The locking member 140 has a pivot end 142 and a free end 143. The pivot end 142 is pivotally attached to the bracket 120 via a locking member pivot installed between the two side walls to pivot the locking member between a locking position and a non-locking position. Here, the locking member pivot is parallel to the engagement hook pivot 151. The second elastic member 154 is provided between the locking member 140 and the bracket 120 to press the locking member 140 to the locking position. When the engagement hook 110 is in the locked position and the cross bar is locked, the locking member 140 is blocked by the cross bar and located at the non-locking position.

[0041] In one embodiment, the locking member 140 has a locking member abutting portion 144 at its free end 143, and the engagement hook 110 has an engagement hook abutting portion 116 corresponding to the locking member abutting portion 144. When the engagement hook 110 is in the unlocking position and the cross bar is released, the locking member 140 is pivoted to the locking position by the pressing of the second elastic member 154, and the locking member abutting portion 144 is brought into contact with the engagement hook abutting portion 116, thereby holding the engagement hook in the unlocking position.

[0042] In one embodiment, when the engagement hook 110 is in the locked position, the first hook portion 111 of the engagement hook 110 protrudes forward to the opening of the recess 121 to lock the cross bar in the recess 121.

[0043] In one embodiment, when the engagement hook 110 is in the unlocked position, the first hook portion 111 of the engagement hook 110 moves away from the opening of the recess 121 by the pivoting of the engagement hook 110, releasing the crossbar.

[0044] In one embodiment, the engagement hook 110 further has a second hook portion 112. The second hook portion 112 is located between the engagement hook pivot 151 and the first hook portion 111, has the same axial position with respect to the engagement hook pivot 151 as the first hook portion 111, extends longer forward than the first hook portion 111, and forms a substantially C-shaped crossbar receiving portion 113 for receiving the crossbar with the first hook portion. When the crossbar is disposed in the receiving portion 113, the second hook portion 112 is configured such that the crossbar presses the second hook portion 112 to pivot the engagement hook 110 from the unlocked position to the locked position.

[0045] In one embodiment, the first hook portion 111 and the second hook portion 112 of the engagement hook 110 and the engagement hook abutting portion 116 of the engagement hook are located at different axial positions with respect to the engagement hook pivot 151, and the locking member abutting portion 114 and the engagement hook abutting portion 116 are located at the same axial position with respect to the engagement hook pivot 151.

[0046] In one embodiment, the joint portion 118 is a pin hole for inserting the pin 152, and the other end of the first elastic member 153 is fixed to the pin 152.

[0047] In one embodiment, the bracket 120 is provided with a pin relief portion 126, and the movement of the pin 152 accompanying the pivoting of the engagement hook 110 is not interfered with by the bracket 120.

[0048] In one embodiment, the engagement hook 110 is joined to the slider 130, and the slider 130 slides to move the engagement hook 110 from the locked position to the unlocked position. An operating member 156 is connected to the end of the slider 130 facing the engagement hook 110. The operating member 156 is formed as a lateral handle with respect to the slider 130, enabling the user to pull the slider 130 from outside the base 400 via the operating member 156.

[0049] In one embodiment, a third elastic member 155 is further provided between the bracket 120 and the engagement hook 110. The third elastic member 155 is a torsion spring and is externally fitted to the engagement hook pivot 151.

[0050] In one embodiment, the vehicle device further includes a front crossbar (320) and a front engagement hook structure (200).
