Description

Technical Field

[0001] This application relates to the field of pet supplies technology, and more particularly to a portable animal pet cart. Background Technology

[0002] Taking your pet on an outdoor excursion isn't always a great experience, as pets may be afraid of unfamiliar environments and unwilling to run around. While it's fine for small pets to be carried, larger pets can be quite tiring and even impossible to carry. This necessitates the use of a pet stroller, but strollers designed for larger pets are inherently bulky, taking up considerable space and making them inconvenient to carry. Summary of the Invention

[0003] The purpose of this application is to provide a portable animal pet vehicle that can be reduced in size.

[0004] To achieve the above objectives, this application provides a portable pet stroller: comprising a tray, with casters at the bottom of the tray, a pair of front folding plates and a pair of rear folding plates rotatably connected to the upper surface of the tray, a straight baffle fixedly connected to the tray to restrict the vertical state of the rear folding plates, a push-pull frame rotatably connected to the tray, and an inclined baffle fixedly connected to the tray to restrict the tilt angle of the push-pull frame, the front folding plates being located between the rear folding plates and the push-pull frame, the side of the front folding plates having a limiting block, the push-pull frame being rotatably connected to a support rod, the end of the support rod away from the push-pull frame being adapted to abut against the lower part of the limiting block, the upper ends of all the front and rear folding plates being rotatably connected to a linkage frame, a front cover connecting the two front folding plates, a rear cover connecting the two rear folding plates, and an elastic cover connecting the front and rear folding plates on the same side, which can well adapt to changes in the relative position of the front and rear folding plates.

[0005] As a preferred embodiment, the upper surface of the tray has a pair of parallel configuration strips, one end of which has a lower front end shaft and the other end has a lower rear end shaft. The axes of the lower front end shaft and the lower rear end shaft are parallel and parallel to the tray. The lower end of the front folding plate cooperates with the lower front end shaft to form a revolute joint, and the lower end of the rear folding plate cooperates with the lower rear end shaft to form a revolute joint, thereby restricting the degree of freedom of movement of the front and rear folding plates relative to the tray.

[0006] As a preferred embodiment, the linkage frame includes a pair of parallel bridging plates, one end of which has an upper front end shaft and the other end has an upper rear end shaft. The upper end of the front folding plate cooperates with the upper front end shaft to form a rotating joint, and the upper end of the rear folding plate cooperates with the upper rear end shaft to form a rotating joint, thereby limiting the relative distance between the upper ends of the front and rear folding plates.

[0007] As a preferred embodiment, a synchronization plate is fixedly connected between the aligned ends of the two bridge plates, and the two synchronization plates are parallel to ensure that the two bridge plates can move synchronously.

[0008] As a preferred embodiment, the inclined baffle and the straight baffle are located on opposite sides of the support plate, and both the inclined baffle and the straight baffle are located on the extension line of the configuration strip, providing relative directional support and restraint to the traction rod and the rear folding plate.

[0009] As a preferred embodiment, the push-pull frame includes a handrail, with traction rods fixedly connected to both ends of the handrail. The two traction rods are parallel, and the end furthest from the handrail is rotatably connected to the support plate to restrict the degree of freedom of movement of the push-pull frame.

[0010] As a preferred embodiment, the upper surface of the tray is fixedly connected to two connecting shafts via a pair of ear plates. The lower ends of the two traction rods away from the handrail respectively cooperate with the two connecting shafts to form a rotating pair. The two rotating pairs can effectively ensure the stability of the push-pull frame.

[0011] As a preferred embodiment, the traction rod has an inner shaft on its side, and one end of the support rod cooperates with the inner shaft to form a rotating pair, thereby restricting the degree of freedom of movement of the support rod.

[0012] Compared with the prior art, the beneficial effects of this application are as follows:

[0013] (1) By designing a rotatable front folding plate and a rear folding plate, and configuring a shielding cloth structure between the folding plates to form a box structure that can prevent pets from entering, the box can be folded to reduce its size and space when not in use, making it more convenient to carry and use.

[0014] (2) By designing the linkage frame and push-pull frame structure, the unfolding and folding operation of the entire pet car is more convenient. Combined with the support rod, slanted baffle and straight baffle structure, the pet car has good stability when unfolded and used. Attached Figure Description

[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are 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. They should not be construed as limiting the specific protection scope of this application.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0030] like Figure 1-10 The portable pet stroller shown includes a rectangular tray 1 with a flat upper surface. Four casters 2 are typically located at the four corners of the tray 1's bottom. A pair of front folding plates 3 and a pair of rear folding plates 4 are rotatably connected to the upper surface of the tray 1. The front folding plates 3 and rear folding plates 4 are parallel and of equal length. A pair of parallel mounting strips 101 are also present on the upper surface of the tray 1. These strips are parallel to the sides of the tray 1. One end of each strip has a lower front axle 103, and the other end has a lower rear axle 104. The axes of the lower front axle 103 and the lower rear axle 104 are parallel and also parallel to the upper surface of the tray 1. The lower end of the front folding plate 3 and the lower front axle 103 cooperate to form a revolute joint, as do the lower end of the rear folding plate 4 and the lower rear axle 104, thus restricting the degrees of freedom of movement of the front folding plates 3 and 4 on the tray 1.

[0031] A straight baffle 105 is fixedly connected to the support plate 1 to restrict the vertical state of the rear folding plate 4. A push-pull frame 6 is also rotatably connected to the support plate 1. The push-pull frame 6 specifically includes a straight handrail 601. Straight traction rods 602 are fixedly connected to both ends of the handrail 601. The two traction rods 602 are parallel to each other. The end of the traction rod 602 away from the handrail 601 is rotatably connected to the support plate 1. In order to achieve the rotatable connection, two connecting shafts 107 are fixedly connected to the upper surface of the support plate 1 through a pair of ear plates 106. The lower front end shaft 103 is located between the connecting shaft 107 and the lower rear shaft 104. The lower ends of the two traction rods 602 away from the handrail 601 are respectively engaged with the two connecting shafts 107 to form a rotating pair. An inclined baffle 102 is fixedly connected to the support plate 1 to limit the tilt angle of the push-pull frame 6. The inclined baffle 102 and the straight baffle 105 are located on opposite sides of the support plate 1, and both the inclined baffle 102 and the straight baffle 105 are located on the extension line of the configuration strip 101, which can provide a good constraint support for the traction rods 602 and the rear folding plate 4.

[0032] It should be noted that the front folding plate 3 is located between the rear folding plate 4 and the push-pull frame 6. The side of the front folding plate 3 facing the push-pull frame 6 has a limiting block 301. The limiting block 301 is close to the upper end of the front folding plate 3. The push-pull frame 6 is rotatably connected to a support rod 7. The side of the traction rod 602 has an inner shaft 603. The inner shaft 603 is close to the lower end of the traction rod 602. One end of the support rod 7 cooperates with the inner shaft 603 to form a rotating pair. The other end of the support rod 7 away from the push-pull frame 6 can abut against the lower part of the limiting block 301 to restrict the rotation of the front folding plate 3, thereby maintaining the vertical state of the front folding plate 3.

[0033] All the upper ends of the front folding plates 3 and the rear folding plates 4 are rotatably connected to a linkage frame 5. The linkage frame 5 is rectangular and includes a pair of parallel bridge plates 501. One end of the bridge plate 501 has an upper front shaft 503 and the other end has an upper rear shaft 504. The two bridge plates 501 have the same structure and are symmetrical to each other. The upper end of the front folding plate 3 cooperates with the upper front shaft 503 to form a rotating pair, and the upper end of the rear folding plate 4 cooperates with the upper rear shaft 504 to form a rotating pair. The distance between the upper front shaft 503 and the upper rear shaft 504 on the same bridge plate 501 is the same as the distance between the lower front shaft 103 and the lower rear shaft 104 on the same configuration strip 101. A synchronization plate 502 is fixedly connected between the aligned ends of the two bridge plates 501. The two synchronization plates 502 are parallel and can ensure that the two bridge plates 501 move synchronously. Therefore, the front folding plate 3, the rear folding plate 4 and the linkage frame 5 can form a rectangular frame.

[0034] A front cover 33 is connected between the two front folds 3, and a rear cover 44 is connected between the two rear folds 4. An elastic cover 34 is connected between the front folds 3 and the rear folds 4 on the same side. A front cover 33, a rear cover 44 and two elastic covers 34 can form the side of a cuboid.

[0035] Working principle: The position where the tray 1 is connected to the push-pull frame 6 is defined as the front, and the position where the tray 1 is connected to the rear folding plate 4 is defined as the rear. In use, place the tray 1 upright, that is, with the casters 2 facing down. First, flip the push-pull frame 6 forward until it is against the inclined baffle 102 and remains tilted. Then, pull the linkage frame 5 backward, which will cause the front folding plate 3 and the rear folding plate 4 to deflect backward until the rear folding plate 4 is against the straight baffle 105 and remains vertical. At this time, the two elastic cover 34, which have been restored to flatness, will be aligned with the front cover. The rear cover 44 and the 33 form a rectangular box with the opening facing upwards. However, the box is unstable and needs to be held by hand. The support rod 7 needs to be tilted backwards so that the upper end of the support rod 7 abuts against the limit block 301 of the front folding plate 3 to limit the rotation of the front folding plate 3. In this way, the rectangular box formed by the front folding plate 3, the rear folding plate 4 and the linkage frame 5 can remain stable. The pet can be put into the box from the top of the box, and the owner can hold the handle 601 and pull the pet stroller together.

[0036] When not in use, the upper end of the support rod 7 can slide out from the lower end of the limiting block 301 and be retracted inside the traction rod 602 to maintain parallelism. Then, push the linkage frame 5 forward to make the front folding plate 3 and the rear folding plate 4 fit as close as possible to the upper surface of the tray 1. During this process, the elastic cover 34 will be noticeably stretched and deformed until it becomes very narrow and very close to the upper surface of the tray 1. Finally, push the push-pull frame 6 backward until it fits against the upper surface of the tray 1. At this point, the entire pet stroller is folded up, resulting in a smaller size. It occupies less space, making it easy to place in a car and carry around.

[0037] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
