Description

Technical Field

[0001] This application relates to the field of stroller technology, specifically to a foldable pet stroller frame. Background Technology

[0002] With the increasing demand for pet transportation, foldable pet strollers have become increasingly popular due to their ease of storage and transport. Existing pet strollers typically consist of a frame and a detachable pet basket. The pet basket uses a rigid support structure (such as a metal frame or plastic skeleton) combined with a cover to achieve a three-dimensional storage space.

[0003] However, when storing a pet stroller, users must first disconnect the pet basket from the frame (such as buckles, straps, etc.) and separate the two before removing the support structures of the frame and pet basket. When unfolding the pet stroller, the pet basket and frame must be unfolded separately before the pet basket is installed on the frame. This process involves multiple steps and is inefficient. Repeated disassembly and assembly can easily lead to wear and tear on the connecting structures, and may cause problems such as loose engagement after long-term use. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a foldable pet stroller frame, including a lower frame, handlebars, a basket, and a connecting rod. The handlebars are rotatably connected to the lower frame via a locking mechanism, which locks the handlebars and lower frame in the unfolded position. The basket is rotatably connected to the handlebars. Both ends of the connecting rod are rotatably connected to the lower frame and the basket, respectively, to limit the basket to the unfolded state. The locking mechanism can release the lock on the handlebars and lower frame, so that when the handlebars rotate towards the lower frame under external force, it drives the basket and connecting rod to rotate until they fold together with the lower frame.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the basket frame includes a front frame and a rear frame, the front frame and the rear frame are rotatably connected to the handlebars respectively, the front frame is connected to the lower frame through the connecting rod, and the rear frame is restricted to the unfolded state by a first limiting structure.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the first limiting structure includes a groove provided on the front rail or handlebar, and a stop block is provided in the groove. The rear rail is provided with a limiting block extending into the groove. The limiting block abuts against the lower end of the stop block to limit it in the unfolded state. The rear rail can rotate relative to the handlebar so that the stop block can move in the groove.

[0007] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the front and rear rails are rotatably connected to the handlebars on the same axis, and the groove is provided on the front rail.

[0008] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the basket frame further includes an upper rail, the upper rail is rotatably connected to the handlebars and is limited above the front rail by a second limiting structure.

[0009] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the second limiting structure includes a limiting protrusion provided on the side of the front rail close to the upper rail, and the upper rail is placed on the limiting protrusion.

[0010] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the lower frame includes a front wheel mechanism and a rear wheel mechanism respectively rotatably connected to the handlebars, and the two ends of the connecting rod are respectively rotatably connected to the front wheel mechanism and the front frame to limit the front frame to the unfolded state.

[0011] The beneficial effects of this utility model are as follows: When the trolley frame is folded, when the handlebars rotate downwards under external force, the basket frame rotates with the handlebars until the basket frame and the lower frame are folded. The handlebars can continue to rotate under external force and move closer to the lower frame until they are folded together. When the trolley frame is unfolded, the handlebars rotate upwards under external force, causing the basket frame to rotate upwards until the basket frame is unfolded. The handlebars continue to rotate under external force until the frame is unfolded. The locking mechanism then locks the handlebars and the lower frame in the unfolded position. No multiple steps are required, making it more convenient to use. Attached Figure Description

[0021] Reference Figures 1-4 This application proposes an embodiment of a foldable pet stroller frame, which includes a lower frame 10, a handlebar 20, a basket frame 30, and a connecting rod 40. The handlebar 20 is rotatably connected to the lower frame 10 via a locking mechanism 70, which locks the handlebar 20 and the lower frame 10 in the unfolded position. The basket frame 30 is rotatably connected to the handlebar 20. Both ends of the connecting rod 40 are rotatably connected to the lower frame 10 and the basket frame 30, respectively, to limit the basket frame 30 to the unfolded state. The locking mechanism 70 can release the lock on the handlebar 20 and the lower frame 10, so that when the handlebar 20 rotates closer to the lower frame 10 under the action of external force, it drives the basket frame 30 and the connecting rod 40 to rotate until they fold together with the lower frame 10.

[0022] Referring to the attached drawings, when the locking mechanism 70 locks the handlebars 20 and the lower frame 10 in the unfolded position, the basket frame 30 is mounted on the handlebars 20 and connected to the lower frame 10 and the basket frame 30 via the connecting rod 40. This forms a stable support structure with the basket frame 30, handlebars 20, lower frame 10, and connecting rod 40, allowing the basket frame 30 to stably support the pet. When the foldable pet stroller frame needs to be folded, the locking mechanism 70 unlocks, and the handlebars 20 can rotate relative to the lower frame 10. When the handlebars 20 rotate downwards under external force, the basket frame 30 rotates with the handlebars 20 until it folds with the lower frame 10. The handlebars 20 can then continue to rotate under external force and move closer to the lower frame 10 until it folds with the lower frame 10. This eliminates the need for multiple steps and makes it more convenient to use.

[0023] Similarly, when unfolded, the handlebar 20 rotates upward under the action of external force, which in turn drives the basket frame 30 to rotate upward until the basket frame 30 is unfolded. Then, the handlebar 20 continues to rotate to the unfolded position under the action of external force, and the locking mechanism 70 locks the handlebar 20 and the lower frame 10 in the unfolded position.

[0024] When the handlebars 20 continue to rotate to the unfolded position under external force, the locking mechanism 70 can automatically or manually reset. The structure and working principle of the locking mechanism 70 automatically or manually resetting after the handlebars 20 continues to rotate to the unfolded position under external force are existing technologies in this field. This application does not specifically limit the structure of the locking mechanism 70, as long as it can achieve the position locking of the handlebars 20 and the underframe 10. For example, the locking mechanism 70 can adopt the structure of the first locking component and the second locking component as described in publication number CN222646088U.

[0025] In some embodiments, the basket frame 30 may be constructed from a rigid support bar, with the top of the car cover fixed to the basket frame 30 to form a pet basket for accommodating a pet.

[0026] In this embodiment, the basket frame 30 includes a front rail 31 and a rear rail 32. The front rail 31 and the rear rail 32 are rotatably connected to the handlebars 20. When the locking mechanism 70 is unlocked, the handlebars 20 rotate forward relative to the lower frame 10 and approach the lower frame 10. The front rail 31 is connected to the lower frame 10 through the connecting rod 40. That is, in this application, after the front rail 31 rotates forward with the handlebars 20 and folds with the lower frame 10, the rear rail 32 rotates under the action of external force to fold with the front rail 31.

[0027] In other embodiments, when the locking mechanism 70 is unlocked and the handlebars 20 rotates backward relative to the underframe 10 and approaches the underframe 10, the rear rail 32 is connected to the underframe 10 via the connecting rod 40.

[0028] In order for the rear support bar 32 to support the pet basket cover, in this embodiment, the rear support bar 32 is restricted to the unfolded state by a first limiting structure 50. In some embodiments, the rear support bar 32 can be detachably connected to the handlebars 20 or the front support bar 31 by means of straps or the like to restrict it to the unfolded state. In this embodiment, the first limiting structure 50 includes a groove 51 provided on the front support bar 31 or the handlebars 20, and a stop block 52 is provided in the groove 51. The rear support bar 32 is provided with a limiting block 53 extending into the groove 51. The limiting block 53 abuts against the lower end of the stop block 52 to restrict it to the unfolded state. The rear support bar 32 can rotate relative to the handlebars 20 to allow the stop block 52 to move within the groove 51.

[0029] Referring to the accompanying drawings, in this embodiment, the front rail 31 and the rear rail 32 are coaxially rotatably connected to the handlebar 20, and the groove 51 is provided on the front rail 31, resulting in a more compact structure.

[0030] In another embodiment, the basket frame 30 further includes an upper support rod 33, which is rotatably connected to the handlebars 20 and limited above the front support rod 31 by a second limiting structure 60. When the front support rod 31 and the rear support rod 32 serve as the bottom support structure of the pet basket cover, the upper support rod 33 serves as the top support structure of the pet basket cover, so that the front support rod 31, the rear support rod 32 and the upper support rod 33 can stably support the basket frame 30 of the pet basket.

[0031] Specifically, the second limiting structure 60 includes a limiting protrusion provided on the side of the front rail 31 near the upper rail 33, and the upper rail 33 is placed on the limiting protrusion.

[0032] In this embodiment, the lower frame 10 includes a front wheel mechanism 11 and a rear wheel mechanism 12 that are rotatably connected to the handlebars 20, and the two ends of the connecting rod 40 are rotatably connected to the front wheel mechanism 11 and the front frame 31 respectively to limit the front frame 31 to the unfolded state.

[0033] When in use, the front wheel mechanism 11 and the rear wheel mechanism 12 are supported on the ground. After the locking mechanism 70 is unlocked, the handlebar 20 rotates forward and approaches the front wheel mechanism 11 under the action of external force. The basket frame 30 and the connecting rod 40 rotate to fold with the lower frame 10. The handlebar 20 continues to rotate and approach the lower frame 10 under the action of external force until it folds with the lower frame 10. When the trolley frame is picked up, the front wheel mechanism 11 and the rear wheel mechanism 12 rotate downward under gravity to approach each other to achieve the folding of the entire trolley frame.

[0034] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
