[0002] Animals are good friends of human beings, and more and more people are keeping lovely small animals such as puppies and cats as pets to accompany their daily life. When going out for a walk with pets, a pet stroller needs to be prepared. Most of the existing pet strollers are modified from baby strollers or directly use baby strollers as pet strollers, and the use mode is single, which can only be used as a carrier for pets when going out. When the pet is at home, another pet nest needs to be prepared to accommodate the pet. Moreover, when people use cars to travel, the conventional pet nest needs to be fixed on the car seat with a fixing belt to ensure the safety of the pet. However, such a fixing method sometimes has an unsatisfactory fixing effect, and the fixing belt often comes off. Based on this, some people prepare special car safety seats for pets to connect with the car. However, this undoubtedly increases the number of equipment and raises the cost of keeping pets. Therefore, it is necessary to design a pet stroller to solve the above problems.

[0074] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with specific implementation examples and the accompanying drawings, and the technical solutions of the present application will be described and explained. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments.

[0075] Referring to FIG. 1 to FIG. 4 and FIG. 8 to FIG. 9, the pet stroller 100 provided by the present application comprises a bearing part 1, a handle 2, a front leg 3 and a rear leg 4. The plane where the bottom surface of the bearing part 1 is located is the reference plane 10. The first end 2A of the handle 2 is connected to the bearing part 1 and the handle is located above the reference plane 10. The end of the front leg 3 close to the bearing part 1 and the end of the rear leg 4 close to the bearing part 1 are both pivotally connected to the bearing part 1, and the end of the front leg 3 close to the bearing part 1 and the end of the rear leg 4 close to the bearing part 1 are connected to each other to be linked. Specifically, the first end 2A of the handle 2 is rotatably connected to the bearing part 1. A first locking mechanism 200 that can lock the handle 2 and the bearing part 1 is further arranged between the handle 2 and the bearing part 1. A second locking mechanism 300 that can lock the bearing part 1, the front leg 3 or the rear leg 4 is arranged between the bearing part 1 and the front leg 3 or the rear leg 4. The end of the front leg 3 close to the bearing part 1 is provided with a first gear 31, the end of the rear leg 4 close to the bearing part 1 is provided with a second gear 41, and a third gear 5 that meshes with the first gear 31 and the second gear 41 is arranged between the first gear 31 and the second gear 41 to make the front leg 3 and the rear leg 4 rotate simultaneously. Specifically, the radius of the second gear 41 is greater than the radius of the first gear 31, so that when the stroller is folded, the front leg 3 can rotate faster than the rear leg 4 to make the folding fast. Also, when the stroller is in the stroller mode, the angle formed between the front leg 3 and the rear leg 4 is greater than the angle formed when the front leg 3 and the rear leg 4 are folded on the bearing part 1. The end of the front leg 3 away from the bearing part 1 has a front wheel 32. In this embodiment, the front wheel 32 is connected to the front leg 3 by a connecting block 33, and the connecting block 33 can rotate axially relative to the front leg 3, so that the front wheel 32 can also rotate axially relative to the front leg 3 to form a universal wheel. The end of the rear leg 4 away from the bearing part 1 has a rear wheel 42; the pet stroller 100 has a stroller mode, a carrier mode, a pet nest mode and a folding mode. When the front leg 3 and the rear leg 4 are located below the reference plane 10, the pet stroller 100 can be used as a stroller mode; when the front leg 3 and the rear leg 4 are pivoted to the reference plane 10 or above the reference plane 10, the pet stroller 100 can be used as a folding mode or a pet nest mode or a carrier mode. In this embodiment, the bearing part 1 has the front leg 3 and the rear leg 4 on the opposite sides. The two front legs 3 are connected and reinforced by a first connecting rod 34. The two rear legs 4 are connected and reinforced by a second connecting rod 43, and when the pet stroller 100 is in the pet nest mode or the folding mode, the second connecting rod 43 can be used as a handle to facilitate lifting the pet stroller 100. In order to further reinforce the front leg 3 and the rear leg 4 and improve the reliability of use, the reinforcing mechanism 101 is further arranged between the front leg 3 and the rear leg 4 on both sides.The reinforcing mechanism 101 comprises a supporting rod 102 and a sliding sleeve 103. One end of the supporting rod 102 is pivotally connected to the front leg 3, and the other end is pivotally connected to the sliding sleeve 103. The sliding sleeve 103 is sleeved on the rear leg 4. When the front leg 3 and the rear leg 4 are unlocked and rotated, the supporting rod 102 also rotates, and the sliding sleeve 103 slides on the rear leg 4. When the front leg 3 and the rear leg 4 are locked, the supporting rod 102 and the sliding sleeve 103 are substantially in a straight line, and form a stable triangle with the front leg 3 and the rear leg 4, thereby improving the stability between the front leg 3 and the rear leg 4.

[0076] Further, referring to FIGS. 8-12, the first end 2A and the second end 2B of the handle 2 are arranged in a telescopic manner to facilitate folding of the handle 2 in the carrier 1. Such an arrangement makes the pet stroller 100 more compact in structure and more aesthetically pleasing in appearance when in the pet nest mode. Specifically, the handle 2 comprises a driving assembly 21, a first traction member 22, a clamping mechanism 23, and a plurality of tubular members 24 telescopically sleeved with each other. The tubular members 24 are arranged between the first end 2A and the second end 2B of the handle 2, and the sleeved portions of the tubular members 24 are locked by the clamping mechanism 23. The driving assembly 21 is arranged at the second end 2B of the handle 2 and is linked to the clamping mechanism 23 through the first traction member 22 to drive the clamping mechanism 23 to unlock the sleeved portions of the tubular members 24. In this embodiment, the driving assembly 21 comprises a first driving button 211 and a connecting seat 212. The first driving button 211 comprises a plurality of driving inclined surfaces 2110, and the connecting seat 212 comprises a plurality of connecting holes 2120. One end of the first traction member 22 is accommodated in the connecting hole 2120 and in contact with the driving inclined surface 2110. When the first driving button 211 is pressed, the driving inclined surface 2110 presses the end of the first traction member 22 close to the first operating button 211, thereby driving the end of the first traction member 22 close to the first operating button 211 to slide in the connecting hole 2120 to pull the clamping mechanism 23. Such an arrangement enables the driving assembly 21 to conveniently unlock the handle 2, thereby improving the convenience of use. Specifically, the tubular members 24 are arranged on opposite sides of the carrier 1.

[0077] As shown in FIGS. 10-12, more specifically, the engaging mechanism 23 comprises a first engaging pin 25, a first mounting base 26 and a first slider 27. The first slider 27 is provided with a first driving hole 271 on each side. The first mounting base 26 comprises a guide hole 261. The first slider 27 is slidably accommodated in the first mounting base 26, and the first slider 27 is further connected with the first traction member 22. In order to reset the first slider 27, a reset member 220 is further arranged between the first slider 27 and the first mounting base 26. The reset member 220 is a compression spring, and both ends thereof abut against the first slider 27 and the first mounting base 26, respectively. The first engaging pin 25 is slidably accommodated in the first slider 26, and one end thereof extends out of the first slider 27 and the first mounting base 26, thereby penetrating the sleeving position of two adjacent pipe members 24 to lock the sleeving position. A sliding pin shaft 251 is further arranged between both ends of the first engaging pin 25, the sliding pin shaft 251 penetrates the first engaging pin 25, and both ends of the sliding pin shaft 251 are accommodated in the first driving hole 271 and the guide hole 261, respectively. When the driving assembly 21 pulls the first slider 27 by the first traction member 22, the first engaging pin 25 slides along the first driving hole 261 and exits the sleeving position of two adjacent pipe members 24, thereby releasing the sleeving position of two adjacent pipe members 24. More specifically, the second end 2B of the user 2 is an operating handle, and both ends of the operating handle are connected with the pipe members 24 on the opposite sides of the bearing part 1, thereby facilitating the pushing of the pet stroller 100 in the stroller mode.

[0078] Further, referring to FIGS. 1-7, the carrying part 1 is further provided with a cover 6 and a shielding member 7. The cover 6 covers the opening of the carrying part 1, and a first end 61 of the cover 6 is pivotally connected to a first end 1A of the carrying part 1. The shielding member 7 is foldably arranged between a second end 62 of the cover 6 and a second end 1B of the carrying part 1 to form a containing space for containing a pet. The shielding member 7 can be pivoted and lowered in height together with the cover 6, and thus is folded at the second end 1B of the carrying part 1. Specifically, the cover 6 is fixedly connected to the handle 2, so that the cover 6 and the handle 2 are synchronously rotated to facilitate folding of the cover 6 and the shielding member 7 together in the carrying part 1. In the embodiment, the shielding member 7 is made of flexible material and internally provided with a supporting framework. When the handle 2 is pivoted towards the carrying part 1, the cover 6 is lowered in height and presses the shielding member 7 downwards, so that the shielding member 7 is folded towards the carrying part 1.
