[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0019] like Figures 1-5 As shown, the device includes a folding mechanism 2 and a flipping mechanism 3. The folding mechanism 2 includes a base 201 and a top frame 202 that correspond to each other. The base 201 and the top frame 202 are connected by a first support rod 204 and a second support rod 203 that are hinged to each other in the middle. The bottom end of the first support rod 204 is hinged to the base 201, and the top end is slidably connected to the top frame 202. The top end of the second support rod 203 is hinged to the top frame 202, and the bottom end is slidably connected to the base 201. There are two of each of the first support rods 204 and the second support rod 203 arranged side by side, and the hinge angle is controlled by an electric telescopic rod 212. The flipping mechanism 3 includes a connecting rod 301 fixed behind the top frame 202. The connecting rod 301 is arranged on the left and right sides, and both ends of it are rotatably connected to a rotating head 303. A handrail 302 is connected between the two rotating heads 303.

[0020] A first crossbar 209 is fixedly connected between the top ends of the two first support rods 204, and a second crossbar 211 is fixedly connected between the bottom ends of the two second support rods 203. Rollers 210 are rotatably connected to both ends of the first crossbar 209 and the second crossbar 211. The base 201 and the top frame 202 have sliding grooves 208 on both sides of the sidewalls corresponding to the rollers 210, with the rollers 210 embedded in the grooves 208 and rolling in connection with them. A fixing rod 205 is fixedly connected between the bottom ends of the two second support rods 203. The fixed end of the electric telescopic rod 212 is rotatably connected to the fixing rod 205, and the output end is rotatably connected to the second crossbar 211.

[0021] Therefore, when the pet stroller is unfolded, the electric telescopic rod 212 retracts and drives the second crossbar 211, causing the rollers 210 at both ends of the second crossbar 211 and the first crossbar 209 to roll along the grooves 208 of the base 201 and the top frame 202. This causes the first support rod 204 and the second support rod 203, which are connected in a cross manner, to gradually converge, thereby allowing the base 201 and the top frame 202 to be opened up and down. The length of the electric telescopic rod 212 can be controlled according to the user's height and the pet's size to control the overall height of the stroller, making it convenient to use.

[0022] When folded, the electric telescopic rod 212 extends, causing the first support rod 204 and the second support rod 203 to fold into the bottom tray 201. At this time, the bottom tray 201 and the top frame 202 are interlocked, which protects the internal parts and ensures the stability of the trolley after folding. The output end of the electric telescopic rod 212 is rotatably connected to the second crossbar 211. The electric telescopic rod 212 on the second support rod 203 is rotatably installed through the fixing rod 205, and its output end is connected to the second crossbar 211, providing automatic driving force. When extended, it pushes the second crossbar 211 to drive the roller 210 to move along the slide groove 208, realizing the automatic folding of the trolley; when retracted, it pulls the second crossbar 211 to complete the automatic unfolding, without manual force, improving the convenience of operation.

[0023] like Figures 2-3 As shown, a carrying basket 206 is fixed above the top frame 202, and a sunshade 207 is rotatably connected to the carrying basket 206 via a damping pivot. The carrying basket 206 on the top frame 202 is used to place pets, providing them with a comfortable riding space. The outer sunshade 207 rotates via the damping pivot, allowing the opening and closing angle to be adjusted according to weather conditions, blocking sunlight or wind and rain, protecting pets from external environmental influences, and improving the pet's riding experience. A waterproof cover is attached to the bottom of the carrying basket 206 with Velcro, and several breathable mesh openings are provided on the sides of the carrying basket 206. The waterproof cover inside the carrying basket 206 is attached with Velcro to prevent pet urine from wetting the basket, and the Velcro is easy to remove and clean; the breathable mesh ensures air circulation inside the carrying basket 206, preventing pets from getting stuffy and maintaining a comfortable and dry riding environment.

[0024] like Figure 5 As shown, a dual-axis self-locking motor 304 is fixed inside the connecting rod 301. The output ends on both sides of the dual-axis self-locking motor 304 are respectively connected to a pair of rotating heads 303. The dual-axis self-locking motor 304 can drive the rotating heads 303 on both sides to rotate synchronously, precisely adjusting the angle of the armrest 302 to meet the needs of users of different heights; the self-locking function can fix the position of the armrest 302, preventing the armrest 302 from rotating accidentally during pushing, and ensuring the stability of use.

[0025] One embodiment of the subject 1 of this application includes a base 101, with a base support 201 fixed to the top of the base 101. The base 101 has two front wheels that are fixed wheels 102 and two rear wheels that are omnidirectional wheels 103, with brake feet on the omnidirectional wheels 103. The base 101 provides bottom support for the folding mechanism 2, the fixed wheels 102 ensure smooth straight-line travel of the stroller, and the omnidirectional wheels 103 facilitate flexible steering to adapt to complex road conditions. The brake feet on the omnidirectional wheels 103 can lock the wheels at any time to prevent the stroller from sliding when parked, ensuring the safety of the pet.

[0026] The pet stroller is powered by a battery 104, which is electrically connected to the electric telescopic rod 212 and the dual-axis self-locking motor 304 via wires. The battery 104 on the base 101 provides an independent power source for the electric telescopic rod 212 and the dual-axis self-locking motor 304, allowing the battery 104 to be charged without the need for external power cords, making it convenient for outdoor use. The wire connection ensures stable power transmission, guarantees the normal operation of the automatic folding and armrest adjustment functions, and enhances the stroller's practicality.

[0027] Specifically, when using this type of folding pet stroller, the battery 104 on the base 101 first powers the electric telescopic rod 212. The electric telescopic rod 212 retracts and drives the second crossbar 211, causing the rollers 210 at both ends of the second crossbar 211 and the first crossbar 209 to roll along the grooves 208 of the base 201 and the top frame 202. This causes the first support rod 204 and the second support rod 203, which are connected crosswise, to gradually converge, thereby opening the base 201 and the top frame 202 vertically. At the same time, the base 101 provides bottom support. Then, the pet is placed in the carrying basket 206 on the top frame 202. The waterproof cover inside the carrying basket 206, which is attached with Velcro, can prevent pet urine from getting into the water. The breathable mesh ensures air circulation. If there is sun or rain, the sunshade 207 can be rotated by the damping pivot to provide shade. Based on the user's height requirements, the dual-axis self-locking motor 304 inside the connecting rod 301 is powered by the battery 104. The dual-axis self-locking motor 304 drives the rotating head 303 to rotate, and the handle 302 is adjusted to a suitable angle and then self-locked. When pushing the trolley, the directional wheel 102 at one end of the base 101 ensures smooth straight-line travel, while the universal wheel 103 at the other end facilitates flexible turning. When stopping, the brake foot of the universal wheel 103 is stepped on to lock the wheel. When folding and storing, the electric telescopic rod 212 is extended, pushing the second crossbar 211 to make the roller 210 roll in the opposite direction, causing the first support rod 204 and the second support rod 203 to rotate crosswise and reduce the height. Finally, the base 201 and the top frame 202 are fastened together, and the handle 302 is rotated to one end to reduce the overall space occupied, completing the folding and storage.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
