Description

Technical Field

[0001] This utility model belongs to the technical field of children's vehicle equipment. Background Technology

[0002] A children's vehicle is a small vehicle designed for infants and toddlers to ride. To provide more recreational functions, children's vehicles often include a rear frame structure.

[0003] For example, Chinese design patent application CN307020212S, published on December 21, 2021, discloses a children's stroller, which includes a front body and a rear body. A locking mechanism is provided on the front body, and a latch is provided on the rear body. The front body and the rear body are detachably connected together by the locking mechanism and the latch.

[0004] In the aforementioned patent, the locking mechanism adopts a columnar structure, with its bottom connected to the front vehicle body. The latch adopts a ring-shaped structure, connecting to the rear vehicle body. The latch fits onto the locking mechanism, allowing the front and rear vehicle bodies to be detachably connected. In use, if it is necessary to connect the rear vehicle body to the front vehicle body, the latch is moved above the locking mechanism and then downwards to engage. When the rear vehicle body is not needed, the latch is moved upwards along the height of the locking mechanism to detach from it.

[0005] In this structure, since the locking mechanism and the latch can be directly disassembled in the height direction, when encountering uneven road surfaces during use that cause a large height difference between the front and rear of the vehicle, the latch will directly separate from the locking mechanism. Utility Model Content

[0006] The purpose of this invention is to provide a children's stroller that allows the buckle and locking mechanism to be reliably connected together to prevent the front and rear of the stroller from easily separating.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A children's stroller includes a front body and a rear body, which are connected by a locking structure. The locking structure includes a lock seat, a locking mechanism, a latch, an elastic body, and a lifting plate. One end of the locking mechanism is fixedly connected to the lock seat, and the locking mechanism and the latch form a detachable connection. The other end of the locking mechanism forms a disassembly end for the latch to be engaged and disassembled. The lifting plate is rotatably mounted, and the elastic body causes the first end of the lifting plate to be constantly pressed against the locking mechanism and / or the latch, thereby preventing the latch from disengaging from the disassembly end.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the elastic body is a compression spring, one end of the compression spring abuts against the lock seat, and the other end of the compression spring abuts against the second end of the lifting pressure plate.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the lifting plate is provided with a protrusion for the compression spring to be fitted.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the first side arc surface of the protrusion near the first end of the lifting plate forms a slope, and the slope is inclined at the end of the protrusion relative to the root of the protrusion away from the first end of the lifting plate.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the lock seat is provided with a recessed cavity for the insertion of a compression spring.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the cavity wall of the recessed cavity is provided with an inclined opening at a position away from the locking mechanism.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme: the first end of the disassembly end is contacted by the lifting pressure plate, and the height of the locking mechanism is greater than the height of the latch.

[0014] Based on the above scheme and as a preferred embodiment of the above scheme: the lifting plate and the lock seat are rotatably connected, the lock seat is provided with a shaft hole, and the lifting plate is provided with a rotating shaft that matches the shaft hole.

[0015] Based on the above scheme and as a preferred embodiment of the above scheme: a shoulder is provided on the lower edge of the shaft hole on the lock seat, and an arc-shaped groove no larger than a semicircle is provided on the shoulder for the shaft to contact, and the inner surface of the arc-shaped groove is aligned with the hole surface of the shaft hole.

[0016] Based on the above scheme and as a preferred embodiment of the above scheme: the lock seat is connected to the front vehicle body, the lock buckle is connected to the rear vehicle body, the detachable end of the lock mechanism faces upward, the lock mechanism is a columnar structure, and the lock buckle is a ring-shaped structure.

[0017] The outstanding and beneficial technical effects of this utility model compared to the prior art are: This utility model of a children's stroller adopts a rotatable lifting plate structure. Under the action of an elastic element, the lifting plate presses against the locking mechanism and / or the latch, thereby preventing the front and rear of the stroller from easily separating. When the user operates the lifting plate, the lifting plate is lifted in the opposite direction, allowing the latch to be removed from its disassembly position. Attached Figure Description

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0026] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0027] This utility model discloses a children's vehicle, including a front body 1 and a rear body 2, which are connected by a locking structure 3. In this utility model, the front body 1 can be a powered or unpowered children's vehicle. A powered children's vehicle is typically electrically driven; an unpowered children's vehicle is typically propelled by the child's pedals.

[0028] In this invention, the locking structure 3 includes a lock base 4, a locking mechanism 5, a latch 6, an elastic body 7, and a lifting plate 8. In this embodiment, the lock base 4 is fixedly connected to the front vehicle body 1, and the latch 6 is connected to the rear vehicle body 2. Of course, as another embodiment, the lock base can also be connected to the rear vehicle body, and correspondingly, the latch can be connected to the front vehicle body.

[0029] As shown in the figure, one end of the locking mechanism 5 is fixedly connected to the lock base 4. Typically, the locking mechanism 5 and the lock base 4 are an integral structure. In this embodiment, the locking mechanism 5 has a columnar structure. (See figure...) Figure 3 , Figure 5 The locking mechanism 5 extends vertically. In this description, the vertical direction refers to the height direction of the stroller. It should be noted that, in another embodiment, the locking mechanism 5 may also be inclined or extend in an arc with curvature. The other end of the locking mechanism 5 forms a disassembly end 9 for the latch 6 to be inserted and removed. As shown in the figure, the latch 6 is a ring structure, which may be closed in the circumferential direction. As another embodiment of the latch 6, it may also have an opening smaller than the outer diameter of the locking mechanism 5. Of course, the locking mechanism 5 and the latch 6 may also adopt other shapes. In this embodiment, the disassembly end 9 is not directly connected to the lock seat 4. When the latch 6, located outside the lock seat 4, extends to a position higher than the locking mechanism 5, and the through cavity 10 on the latch 6 is directly opposite the locking mechanism 5 in the vertical direction (height direction of the stroller), the latch 6 is moved downward, causing the locking mechanism 5 to be inserted into the through cavity 10, thereby making the locking mechanism 5 and the latch 6 detachably connected.

[0030] In this embodiment, the disassembly end 9 of the locking mechanism 5 faces upward. In another embodiment, the disassembly end 9 of the locking mechanism 5 may also face downward, and correspondingly, the lifting plate 8 is located below the disassembly end 9.

[0031] The lifting plate 8 is rotatably mounted, with its first end corresponding to the disassembly end 9.

[0032] In this embodiment, the lifting plate 8 is mounted on the lock seat 4 and is rotatable relative to the lock seat 4. As shown in the figure, the lock seat 4 has two opposing sidewall portions 11, each with a shaft hole 12. The lifting plate 8 has a rotating shaft 13. The shaft hole 12 and the rotating shaft 13 are adapted to each other, thereby allowing the lifting plate 8 to rotate within a predetermined range around the rotating shaft 13. Of course, the shaft hole 12 can also be provided on the lifting plate 8, and the rotating shaft 13 can also be provided on the lock seat 4.

[0033] In this embodiment, the elastic body 7 is a compression spring. One end of the compression spring abuts against the lock seat 4, and the other end abuts against the second end of the lifting plate 8. Typically, the compression spring is installed below the second end of the lifting plate 8 in a pre-compressed state. This allows the first end of the lifting plate 8 to have a predetermined pressing force towards the locking mechanism 5. As shown in the figure, since the compression spring is in a relatively extended state, when the user does not lift the lifting plate 8, the first end of the lifting plate 8 is relatively close to the disassembly end 9 under the action of the compression spring, forming the normal state of the lifting plate 8, i.e., one end of the lifting plate 8 is constantly pressed against the disassembly end 9. When the user applies a lifting force away from the disassembly end 9 to the first end of the lifting plate 8 and overcomes the resistance of the compression spring, the lifting plate 8 rotates along the pivot 13, and simultaneously the first end of the lifting plate 8 is lifted away from the disassembly end 9, creating a larger distance between the first end of the lifting plate 8 and the disassembly end 9, allowing the latch 6 to disengage. Of course, the elastic body 7 can also use other structures, such as a rubber body instead of a compression spring. In another embodiment of the elastic body 7, the elastic body 7 can also be a tension spring, which is located below the first end of the lifting plate 8. Of course, the elastic body 7 can also be a torsion spring sleeved on the rotating shaft 13.

[0034] As another mounting structure for the lifting plate 8, the lifting plate 8 can also be rotatably mounted on the front vehicle body 1, and the specific connection structure between the lifting plate 8 and the front vehicle body 1 can be similar to the structure in the above embodiment.

[0035] It should be noted that, as a preferred mounting structure of the lifting plate 8 in this utility model, the lifting plate 8 is rotatably connected to the lock seat 4. Thus, the lock seat 4, the lock mechanism 5, and the lifting plate 8 form an integral modular structure, facilitating their installation on the front vehicle body 1.

[0036] As shown in the figure, the first end of the lifting plate 8 is positioned directly opposite the disassembly end 9. The elastic body 7 presses the first end of the lifting plate 8 against the locking mechanism 5, thus preventing the latch 6 from disengaging from the disassembly end 9. In this embodiment, the disassembly end 9 of the locking mechanism 5 is accessible to the first end of the lifting plate 8. After one end of the lifting plate 8 contacts the disassembly end 9, even if the latch 6 moves above the disassembly end 9, the first end of the lifting plate 8 prevents the latch 6 from disengaging from the disassembly end 9 due to the limiting effect of the lifting plate 8. In this embodiment, the size of the first end of the lifting plate 8 is larger than the outer diameter of the disassembly end 9, thus using the first end of the lifting plate 8 to restrict the upward movement of the latch 6, thereby keeping the locking mechanism 5 and the latch 6 connected together. Typically, the height of the locking mechanism 5 is greater than the height of the locking buckle 6, so that the locking buckle 6 has a certain amount of movement in the height direction of the locking mechanism 5, so as to make it suitable for children to ride on uneven roads, especially when the front body 1 and the rear body 2 are tilted in different directions, so that the front body 1 and the rear body 2 can each have a certain posture without interfering with each other.

[0037] In another embodiment, the elastic body 7 presses the first end of the lifting plate 8 against the latch 6. Specifically, the latch 6 is in contact with or near the first end of the lifting plate 8. This structure also prevents the latch 6 from disengaging from the disassembly end 9. In other embodiments, the elastic body 7 presses the first end of the lifting plate 8 against the locking mechanism 5 and the latch 6. Specifically, the first end of the lifting plate 8 contacts or approaches the locking mechanism 5 and the latch 6, thereby preventing the latch 6 from disengaging from the disassembly end 9.

[0038] It should be noted that in the above embodiments, in order to make the lifting plate 8 approach the locking mechanism 5 or the latch 6, a limiting block can be set on the lock seat 4 for the lifting plate 8 to abut against it. The structure of the limiting block can limit the rotation limit position of the lifting plate 8 under the action of the compression spring. In this way, the first end of the lifting plate 8 does not need to directly contact the locking mechanism 5 or the latch 6.

[0039] As shown in the figure, the lifting plate 8 is provided with a protrusion 14 for the compression spring to fit over. In this embodiment, the other end of the compression spring is fitted over the outside of the protrusion 14, and the protrusion 14 positions the other end of the compression spring.

[0040] In this embodiment, the first side arc surface 15 of the protrusion 14 near the first end of the lifting plate 8 forms a slope, and the end 16 of the slope is inclined relative to the root 17 of the protrusion away from the first end of the lifting plate 8. As shown in the figure, since the first side arc surface 15 is a slope structure, a reserved space is formed between the first side arc surface 15 and the compression spring. When the lifting plate 8 is rotated by the user, the end 16 of the protrusion will not push the compression spring laterally, thereby avoiding the compression spring from being subjected to excessive local stress and forming irreversible deformation, and ensuring the service life of the spring. In addition, by adopting the structure of the first side arc surface 15 being a slope, during the rotation of the lifting plate 8, the end 16 of the protrusion will not enter the gap 18 of the compression spring, so the entire compression spring can produce an integral elastic deformation, and the position of the end 16 of the protrusion on the compression spring will not be subjected to local lateral pushing force, ensuring that the compression spring works under good working conditions.

[0041] As shown in the figure, the lock seat 4 is provided with a recessed cavity 19 for inserting a compression spring. Due to the structure of the recessed cavity 19, one end of the compression spring can be inserted, stably maintaining its position. Typically, the depth of the recessed cavity 19 is greater than half the length of the compression spring. As shown in the figure, the cavity wall of the recessed cavity 19 has an inclined opening 20 located away from the locking mechanism 5. Due to the inclined opening 20, the first end of the lifting plate 8 can rotate to a position below the highest cavity wall of the recessed cavity 19. Compared to a structure without the inclined opening 20, the lifting plate 8 is installed at a lower position, resulting in a relatively shorter portion of the compression spring exposed above the highest cavity wall of the recessed cavity 19. Therefore, the recessed cavity 19 also provides a significant guiding effect for the compression spring, preventing or reducing lateral bending during compression deformation, thus effectively ensuring that the compression spring exerts its proper elastic function.

[0042] In this embodiment, the lifting plate 8 is rotatably mounted on the lock seat 4. Specifically, the lock seat 4 is provided with a shaft hole 12, and the lifting plate 8 is provided with a rotating shaft 13 adapted to the shaft hole 12. With this structure, during assembly, the lifting plate 8 is forcibly pressed onto the lock seat 4. During the period when the lifting plate 8 is pressed against the lock seat 4, the lock seat 4 or the lifting plate 8 undergoes elastic deformation, thereby allowing the rotating shaft 13 to be installed into the shaft hole 12. As shown in the figure, the lock seat 4 is provided with a shoulder 21 at the lower edge of the shaft hole 12. The shoulder 21 is provided with a receiving arc-shaped groove 22, no larger than a semicircle, for the rotating shaft 13 to contact. The inner surface of the receiving arc-shaped groove 22 is flush with the hole surface of the shaft hole 12. By setting up a structure that receives the arc-shaped groove 22, since it protrudes from the end face of the shaft hole 12, it can effectively prevent the rotating shaft 13 from going over the shaft hole 12 during the assembly of the lifting plate 8, ensuring that the rotating shaft 13 is accurately assembled into the shaft hole 12.

[0043] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
