Description

Technical Field

[0001] This utility model relates to the field of children's products technology, and in particular to a children's vehicle. Background Technology

[0002] In existing stroller designs, the frame is typically foldable for easy carrying and storage. However, in practice, this folding mechanism often requires operating multiple individual components sequentially to complete the folding process. This not only complicates the user's operation but also reduces ease of use. Utility Model Content

[0003] The main purpose of this invention is to propose a child vehicle that optimizes the folding structure of the child vehicle to simplify the folding operation.

[0004] To achieve the above objectives, this utility model proposes a child vehicle, wherein the child vehicle comprises:

[0005] A foldable bracket includes at least two movable members that are movably connected, the two movable members being foldable during the folding process of the bracket to have a folding stroke, wherein one of the movable members is a driving member;

[0006] A connector, rotatably mounted to the bracket; and,

[0007] A locking structure is provided between the connector and the bracket. The locking structure includes a movably disposed locking member. The locking member has a locking position and an unlocking position during its active stroke. In the locking position, the locking member limits the rotation of the connector. In the unlocking position, the locking member releases the restriction on the connector.

[0008] Specifically, during the folding travel of the driving member, the locking member can be driven to move, so that the locking member moves from the locked position to the unlocked position.

[0009] In one embodiment, the bracket includes a first support rod and a second support rod that are rotatably connected and can rotate toward each other to be folded.

[0010] Wherein, the first support rod is the driving component, the connecting component is rotatably mounted on the second support rod, and the second support rod is provided with a linkage component, one end of which is throttle-connected to the locking component, and the other end of which is throttle-connected to the first support rod.

[0011] In one embodiment, the linkage is movably mounted on the second support rod along the length direction of the second support rod. One end of the linkage is connected to the driving member and the other end is connected to the locking member. During the rotation and folding process, the driving member drives the linkage to extend and retract, thereby driving the locking member to move from the locked position to the unlocked position.

[0012] In one embodiment, the rotating part of the driving member has a driving surface, the driving surface abuts against one end of the linkage member, and the distance between the driving surface and the rotating shaft of the driving member is gradually changed, so as to drive the linkage member to extend and retract during rotation.

[0013] In one embodiment, the locking member is telescopically mounted on the second support rod along the rotation axis of the connector, and has a mating portion in the rotation axis direction of the connector. The locking member has a locking position close to the connector and an unlocking position away from the connector during its telescopic stroke.

[0014] The other end of the linkage component has a drive portion formed on its side surface that abuts against the mating portion;

[0015] One of the mating part and the driving part is provided with a driving slope so that when the linkage moves away from the driving part, the locking part can be driven to move away from the connecting part.

[0016] In one embodiment, the locking member has a pin portion that extends out of the second support rod, and the connecting member has a pin hole laterally facing the second support rod, the pin hole being located laterally to the rotation axis of the connecting member. During its extension and retraction stroke, the locking member has a locking position where the pin portion extends into the pin hole, and an unlocking position where the pin portion disengages from the pin hole; and / or,

[0017] An elastic reset member is provided between the mating part and the second support rod. The elastic reset member is used to reset the locking member from the unlocked position to the locked position.

[0018] In one embodiment, the bracket includes two first support rods and a second support rod. The two first support rods are rotatably connected about a transverse axis and can rotate close to each other for folding. Each of the two first support rods has a support segment, which extends longitudinally away from the rotation points of the two first support rods in a direction away from each other. Each of the two support segments is provided with a rolling portion. One of the first support rods serves as the driving member, and the second support rod is connected to the rotation points of the two first support rods; and / or,

[0019] The connector is a handrail or canopy assembly; and / or,

[0020] An elastic element is provided between the rotatable connection of the connector and the second support rod.

[0021] In one embodiment, the bracket includes a first support rod and a second support rod that are rotatably connected and can rotate toward each other to be folded.

[0022] The connector is rotatably mounted on the second support rod. One end of the locking member is connected to the connector, and the other end extends along the side of the second support rod and extends beyond the side of the second support rod opposite to the connector.

[0023] The locking member has a locking position that engages the second support rod and an unlocking position that disengages from the second support rod. The first support rod is the driving member. During the folding stroke of the driving member, when the driving member approaches the second support rod, it drives the locking member to rotate relative to the second support rod, thereby driving the locking member to disengage from the second support rod to the unlocking position.

[0024] In one embodiment, a mating part is provided on one side of the locking member, the mating part including a slot formed on the locking member, and a fastening part is provided on the second support rod, the fastening part including a locking block disposed on the side of the second support rod, wherein in the locked position, the locking block is engaged in the slot;

[0025] The locking element is elastically deformable.

[0026] In one embodiment, the child vehicle includes:

[0027] The front and rear supports are rotatably connected about a transverse axis; one end of the second support rod is connected to the rotatable portion of the front and rear supports, and the other end extends upward; and...

[0028] Two bottom support rods, one end of which is rotatably connected, and the other end is rotatably connected to the front bracket and the rear bracket respectively;

[0029] Wherein, the middle part of the first support rod is rotatably connected to the rear bracket or the front bracket, the upper end is movably connected to the upper end of the second support rod, and the lower end is rotatably connected to the sleeve fitted on the bottom support rod. When the child carrier is folded, the first support rod and the second support rod move closer together, driving the locking member to move to the unlocked position; and / or,

[0030] The connector is a handrail or canopy assembly; and / or,

[0031] An elastic element is provided between the rotatable connection of the connector and the second support rod.

[0032] In the technical solution of this utility model, when the support of the child carrier is folded, the connecting member can be unlocked, allowing the connecting member to fold under its own weight without additional manual operation, thus simplifying the operation process and making it more convenient and practical. Specifically, the support includes at least two movable members with a folding stroke, and the connecting member is rotatably mounted on the support. A locking structure is provided at the rotatable mounting point of the connecting member and the support. Based on the folding stroke of the two movable members, the aim is to use their folding stroke to drive the locking structure to unlock. Therefore, in this application, one of the movable members is set as the driving member. Its folding movement drives the locking member to move, thereby driving the locking member to move from the locked position to the unlocked position, completing the linkage unlocking of the connecting member and simplifying the operation.

[0056] In existing stroller designs, the frame is typically foldable for easy carrying and storage. However, in practice, this folding mechanism often requires operating multiple individual components sequentially to complete the folding process. This not only complicates the user's operation but also reduces ease of use.

[0057] In view of this, this utility model proposes a child vehicle; please refer to [link / reference]. Figures 1 to 16 The following is an embodiment of the child vehicle proposed in this application, and the child vehicle will be described in detail below with reference to the specific drawings.

[0058] Please see Figure 1 or Figure 8The child carrier 100 includes a foldable support 1, a connector 2, and a locking structure. The foldable support 1 includes at least two movably connected movable members, which are foldable during the folding process to have a folding stroke. One of the movable members is a driving member. The connector 2 is rotatably mounted on the support 1. The locking structure is disposed between the connector 2 and the support 1. The locking structure includes a movably disposed locking member 3, which has a locked position and an unlocked position on its stroke. In the locked position, the locking member 3 limits the rotation of the connector 2. In the unlocked position, the locking member 3 releases the restriction on the connector 2. During the folding stroke of the driving member, the locking member 3 can be driven to move from the locked position to the unlocked position.

[0059] In the technical solution of this utility model, when the support 1 of the child carrier 100 is folded, the connecting member 2 can be unlocked, so that the connecting member 2 can be folded by its own gravity without additional manual operation, thereby simplifying the operation process and making it more convenient and practical. Specifically, the support 1 includes at least two movable members with folding strokes, and the connecting member 2 is rotatably mounted on the support 1. A locking structure is provided at the rotatable mounting point of the connecting member 2 and the support 1. Based on the folding strokes of the two movable members, the locking structure is unlocked by using their folding strokes. Therefore, in this application, one of the movable members is set as the driving member. Its folding movement drives the locking member 3 to move, thereby driving the locking member 3 from the locked position to the unlocked position, completing the linkage unlocking of the connecting member 2, and simplifying the operation.

[0060] Please see Figures 1 to 2In the first embodiment of the child carrier 100 provided in this application, the bracket 1 includes a first support rod 11 and a second support rod 12 that are rotatably connected and can rotate close to each other to be folded; wherein, the first support rod 11 is the driving member, the connecting member 2 is rotatably mounted on the second support rod 12, and a linkage member 4 is provided on the second support rod 12. One end of the linkage member 4 is throttlely connected to the locking member 3, and the other end is throttlely connected to the first support rod 11. In this embodiment, the two movable parts are configured as two support rods of the child carrier 100. Specifically, the two support rods include a first support rod 11 and a second support rod 12. The first support rod 11 and the second support rod 12 are rotatably connected. During the folding process of the child carrier 100, the first support rod 11 and the second support rod 12 rotate toward each other to achieve folding of the first support rod 11 and the second support rod 12. Based on this, the connecting member 2 is disposed on the second support rod 12, and the locking structure is disposed between the connecting member 2 and the second support rod 12. The first support rod 11 is configured as the driving member. It can be understood here that the first support rod 11 acts as the driving member to drive the locking structure. The movement of the locking member 3 is not limited. For example, it can act directly on the locking member 3 during the process of the first support rod 11 folding close to the second support rod 12, or it can act on the locking member 3 through a transmission structure. In this embodiment, the second support rod 12 is also provided with the linkage member 4, so that at least the rotation and folding action of the first support rod 11 and the unlocking action of the locking member 3 can be linked through the linkage member 4. In this way, the first support rod 11 does not need to act directly on the locking member 3, so that the relative positional relationship between the two is less related, and the setting of the linkage member 4 is more flexible. It only needs to be able to link the first support rod 11 and the locking member 3. The structural and functional restrictions are less, which facilitates the overall structural and functional design of the child carrier 100.

[0061] Specifically, see Appendix Figure 4 and appendix Figure 6The linkage 4 is movably installed on the second support rod 12 along the length direction of the second support rod 12. One end of the linkage 4 is connected to the driving member and the other end is connected to the locking member 3. During the rotation and folding process, the driving member drives the linkage 4 to extend and retract, so as to drive the locking member 3 to move from the locked position to the unlocked position. As described above, the specific structure of the linkage 4 does not need to be limited. It mainly depends on the specific structure of the first support rod 11 and the locking member 3, as long as it can link the first support rod 11 and the locking member 3. For example, the linkage 4 can be set as a linkage structure, gear linkage structure, traction structure, etc. In this embodiment, the linkage 4 is set to move along the length direction of the second support rod 12, and the linkage 4 is driven to extend and retract along the length direction of the second support rod 12 by the rotation and folding of the driving member, so as to realize the linkage between the first support rod 11 and the locking member 3. With this setting, the linkage 4 is attached to the second support rod 12, and when it moves, it also extends and retracts along the extension direction of the second support rod 12, so that the linkage 4 has no other direction of movement, the movement path is simple, it is easy to set, and it is relatively stable during the movement. Specifically, in this embodiment, the linkage 4 is set inside the second support rod 12, simplifying the external structural features of the child carrier 100, so as to ensure the safety of the child carrier 100 when folded.

[0062] Furthermore, the telescopic arrangement of the linkage 4 along the length of the second support rod 12 has been described above. The first support rod 11 is rotatably mounted on the second support rod 12. That is, it is necessary to convert the rotation of the first support rod 11 relative to the second support rod 12 into the telescopic movement of the linkage 4 along the length of the second support rod 12. For example, it can be set as a gear and rack linkage structure, where the rotation of the gear drives the rack to move. In this embodiment, the rotating part of the driving member has a driving surface 13, which abuts against one end of the linkage 4. The distance between the driving surface 13 and the rotating shaft of the driving member is gradually changed so as to drive the linkage 4 to telescopically move during rotation. That is, the driving surface 13 is provided at the rotation point of the first support rod 11, which is also the driving member, and the driving surface 13 is set as an inclined surface with a gradually changing distance from the rotation axis of the driving member. One end of the linkage 4 abuts against the driving surface 13, so that when the first support rod 11 rotates relative to the second support rod 12, one end of the linkage 4 moves along the driving surface 13, so that the distance between one end of the linkage 4 and the rotation axis of the first support rod 11 gradually changes, thereby allowing the linkage 4 to extend and retract along the length direction of the second support rod 12 to meet the functional requirements.

[0063] Furthermore, the locking member 3 is telescopically mounted on the second support rod 12 along the rotation axis of the connecting member 2, and has a mating part 31 in the rotation axis direction of the connecting member 2. During its telescopic stroke, the locking member 3 has a locking position close to the connecting member 2 and an unlocking position away from the connecting member 2; please refer to [link / reference] for details. Figure 7 The other end of the linkage 4 has a side surface with a driving part 41 that abuts against the mating part 31; wherein, one of the mating part 31 and the driving part 41 is provided with a driving slope, so that when the linkage 4 moves away from the driving part, the locking part 3 can be driven away from the connecting part 2. The connecting part 2 is rotatably mounted on the second support rod 12 as described above. Generally, the rotation axis of the connecting part 2 is perpendicular to the extension direction of the second support rod 12 to avoid interference of the second support rod 12 with the rotation process of the connecting part 2. Based on this, the locking part 3 can be configured to extend and retract along the rotation axis of the connecting part 2 on the second support rod 12, so that the locking part 3 has a locking position that extends to the rotation stroke of the connecting part 2 to restrict the rotation of the connecting part 2, and a retracting position that returns to the second support rod 12 to avoid the unlocking position of the connecting part 2. The vertical spatial relationship of the extension direction of rod 12 requires that the extension and retraction of the linkage 4 on the second support rod 12 be converted into the extension and retraction of the locking member 3 in the direction of the rotation axis of the connector 2. Therefore, in this embodiment, the driving inclined surface is provided on one of the linkage 4 and the locking member 3, so that when the linkage 4 moves along the second support rod 12 to move away from the driving member, the driving inclined surface can drive the locking member 3 to move along the rotation axis of the connector 2, that is, drive the locking member 3 from the locked position to the unlocked position, so as to complete the function of automatically releasing the connection 2 from the second support rod 12 during the folding process of the bracket 1.

[0064] Specifically, the locking member 3 can be configured in various ways, such as a clamping structure. When the clamping structure extends out of the second support rod 12 along the rotation axis of the connector 2, the clamping structure clamps onto the connector 2 to restrict the rotation of the connector 2. In this embodiment, the locking member 3 is configured to have a pin connection 32 that can extend out of the second support rod 12, and a pin hole 21 is provided on the side of the connector 2 facing the second support rod 12. The pin hole 21 is located on the side of the rotation axis of the connector 2, so that in the extension and retraction stroke of the locking member 3, there is a locking position in which the pin connection 32 extends into the pin hole 21, and an unlocking position in which the pin connection 32 disengages from the pin hole 21. The structure is simple and the effect is good. On the one hand, in order to facilitate the quick locking of the connecting member 2 to its desired locking position when the child vehicle 100 is re-unfolded, and on the other hand, to ensure the stability of the locking member 3 in the locking position, this embodiment also provides an elastic reset member 5 between the mating part 31 and the second support rod 12 on the locking member 3. The elastic reset member 5 is used to reset the locking member 3 from the unlocked position to the locked position to meet the above requirements.

[0065] Furthermore, the bracket 1 includes two first support rods 11 and a second support rod 12. The two first support rods 11 are rotatably connected about a transverse axis and can rotate close to each other for folding. Each of the two first support rods 11 has a support section 111, which extends longitudinally away from each other from the rotation point of the two first support rods 11. Each of the two support sections 111 is provided with a rolling part 112. Thus, the two first support rods 11 form a movable base for the child carrier 100. One of the two first support rods 11 is the driving component required in this application. The second support rod 12 is connected to the rotation point of the two first support rods 11 to support the connecting member 2 and other structures. When the first support rods 11 are folded, the second support rod 12 can fold close to the first support rods 11 to meet the folding function requirement. Specifically, the connecting member 2 provided on the child carrier 100 can be an armrest or a canopy assembly to suit different usage requirements of the child carrier 100.

[0066] Furthermore, based on the requirement for the rapid deployment of the child carrier 100, the automatic elastic reset of the locking member 3 has been described above. In this embodiment, an elastic member is also provided between the rotating connection of the connecting member 2 and the second support rod 12. The connecting member 2 can be quickly reset to the desired locking position through the elastic member. On the other hand, since the connecting member 2 can move relative to the second support rod 12 after unlocking, the elastic member can keep the connecting member 2 in a folded state to prevent it from shaking. The elastic members used in the above two scenarios have opposite force directions and cannot be set synchronously. The actual usage is not limited in this application, but depends on the specific needs.

[0067] Please see Figure 8 and Figure 9 In the second embodiment of the child carrier 100 provided in this application, the bracket 1 includes a first support rod 11 and a second support rod 12 rotatably connected, which can rotate close to each other to be folded; the connector 2 is rotatably mounted on the second support rod 12; one end of the locking member 3 is connected to the connector 2, and the other end extends along the side of the second support rod 12 and extends beyond the side of the second support rod 12 opposite to the connector 2; the locking member 3 has a locking position for engaging the second support rod 12 and an unlocking position for disengaging from the second support rod 12; the first support rod 11 is the driving member; during the folding stroke of the driving member, when the driving member approaches the second support rod 12, it drives the locking member 3 to rotate relative to the second support rod 12, so as to drive the locking member 3 to disengage from the second support rod 12 to the unlocking position. The locking member 3 in this embodiment is different from the locking member 3 in the first embodiment. The locking member 3 in the first embodiment is unlocked by transmission structure, namely the linkage member 4, and is maintained in the locked state of the connecting member 2 by the elastic reset member 5. The structure is more flexible but more complex. In the second embodiment, the locking member 3, which is clamped between the connecting member 2 and the second support rod 12, is in direct contact with the first support rod 11. The first support rod 11 pushes the locking member 3 to rotate relative to the second support rod 12 to release the clamping state between the locking member 3 and the second support rod 12. This causes the connected connecting member 2 to rotate relative to the second support rod 12 or the connected connecting member 2 to rotate automatically when it loses its limit, thereby realizing the folding of the connecting member 2 and meeting the functional requirements. This setting is the opposite of the first embodiment of the child carrier 100 described above. The structure of the locking member 3 and the first support rod 11 cooperating to unlock is simpler, but the relative position setting is more restricted and the design freedom is lower.

[0068] Furthermore, to ensure that the locking member 3 is engaged between the connecting member 2 and the second support rod 12, thereby limiting the connecting member 2 while facilitating the locking member 3 to disengage from the engaged state after being pushed by the first support rod 11, in this embodiment, see Appendix Figure 14 and appendix Figure 15 The locking member 3 has a mating part 31 on one side, which includes a slot on the locking member 3. The second support rod 12 has a fastening part 121, which includes a latching block on the side of the second support rod 12. In the locked position, the latching block is engaged in the slot, and the locking member 3 is elastically deformable. That is, the connecting member 2 is locked by the latching block being engaged in the slot on the locking member 3. At the same time, the elastic deformation of the locking member 3 allows the latching block to disengage from the slot when the first support rod 11 pushes against the locking member 3 to rotate, thus unlocking the locking member 3. Conversely, the deformation of the locking member 3 allows the latching block to re-engage in the slot, thus locking the connecting member 2. The structure is simple, effective, and meets functional requirements.

[0069] Specifically, the child carrier 100 includes a front support 8, a rear support 9, and two bottom support rods 6. The front support 8 and the rear support 9 are rotatably connected around a transverse axis. One end of the second support rod 12 is connected to the rotatable part of the front support 8 and the rear support 9, and the other end extends upward. One end of the two bottom support rods 6 is rotatably connected, and the other end is rotatably connected to the front support 8 and the rear support 9, respectively. The middle part of the first support rod 11 is rotatably connected to the rear support 9 or the front support 8, the upper end is movably connected to the upper end of the second support rod 12, and the lower end is rotatably connected to the sleeve 7 sleeved on the bottom support rod 6. When the child carrier 100 is folded, the first support rod 11 and the second support rod 12 approach each other, driving the locking member 3 to move to the unlocked position. The child carrier 100 has a base formed by the front support 8 and the rear support 9. The first support rod 11 and the second support rod 12 are both disposed on the base. Two bottom support rods 6 connect the front support 8 and the rear support 9 to limit the maximum opening position of the front support 8 and the rear support 9, ensuring their stability as a base. The two bottom support rods 6 are rotatably connected, allowing for folding and meeting the folding requirements of the child carrier 100 as proposed in this application. In this embodiment, the bottom of the first support rod 11 is rotatably connected... A sleeve located on the bottom support rod 6, with its middle portion rotatably connected to the rear bracket 9, allows the folding of the front bracket 8 and the rear bracket 9 during the folding process of the child carrier 100 to be synchronized with the folding rotation of the two bottom support rods 6. Furthermore, the folding rotation of the two bottom support rods 6 is synchronized with the folding rotation of the first support rod 11 and the second support rod 12, thus synchronizing the overall folding of the child carrier 100. Only one folding action is needed to complete the folding of multiple joints of the child carrier 100, making it simple and easy to use. Specifically, the connecting member 2 on the child carrier 100 can be a handrail or a canopy assembly to suit different usage needs of the child carrier 100.

[0070] Furthermore, based on the requirement for rapid deployment of the child carrier 100, similar to the first embodiment described above, this embodiment also provides an elastic element between the rotating connection of the connector 2 and the second support rod 12. This elastic element allows the connector 2 to be quickly reset to the desired locking position. On the other hand, since the connector 2 can move relative to the second support rod 12 after unlocking, the elastic element keeps the connector 2 in a folded state, preventing it from wobbling. The elastic elements used in these two scenarios apply force in opposite directions and cannot be set synchronously. This application does not limit their actual use; the specific requirements will prevail.
