[0038] By providing the front wheel slide 2 and connecting the front wheel fixing mechanism 3 to the front wheel slide 2, when the front wheel slide 2 slides forward and backward along the frame body 11, the front wheel fixing mechanism 3 can be driven to slide forward and backward along the frame body 11. When in use, the user presses the front wheel of the vehicle over the front wheel turning portion 32, so that the front wheel turning portion 32 turns forward toward the direction of the front wheel fixing portion 31. The front wheel turning portion 32 is pressed by the dead weight of the front wheel, and the front and rear ends of the front wheel are respectively in contact with the front wheel fixing portion 31 and the front wheel turning portion 32. , so as to lock the front wheel in the front wheel accommodating groove 33; then, a forward thrust is applied to the vehicle at the rear end of the vehicle, so that the front wheel slide 2 drives the front wheel fixing mechanism 3 to move forward until the rear wheel of the vehicle presses over the rear wheel flipping portion 43, so that the rear wheel flipping portion 43 flips forward toward the rear wheel fixing portion 42, and the rear wheel flipping portion 43 is pressed by the dead weight of the rear wheel. The front and rear ends of the rear wheel are respectively in contact with the rear wheel fixing portion 42 and the rear wheel flipping portion 43, so as to lock the rear wheel in the rear wheel accommodating groove 44, thereby completing the parking operation.

[0039] By providing the front wheel fixing portion 31 and the front wheel flipping portion 32, the front wheels are locked in the front wheel receiving grooves 33 by their own weight during parking, so that the vehicle is not easy to tip over during the entire pushing process. When parking, the user does not need to move forward following the forward movement of the vehicle. At the same time, a rear wheel fixing mechanism 4 is provided, and the rear wheel fixing mechanism 4 includes the rear wheel fixing portion 42 and the rear wheel flipping portion 43, so that the rear wheels of the vehicle are also locked in the rear wheel receiving grooves 44 by their own weight. Therefore, after parking, the vehicle no longer needs to be supported by the vehicle's own tripod, making it convenient to park and fix the vehicle, and solving the problem in the prior art that the vehicle needs to lower its own tripod for support after parking, which is inconvenient to fix the vehicle.

[0040] In addition, the self-weight locking parking device of the present invention does not require space to be reserved for users to move forward and a position to put down the vehicle tripod, which helps to reduce the width of the self-weight locking parking device. There is no need to reserve space for users to move forward and a position to put down the vehicle tripod, avoiding the problem of a single parking platform being too wide and having low space utilization.

[0041] At the same time, by arranging the sunken mounting frame 41 in the mounting cavity 111, the rear wheel fixing mechanism 4 can be hidden inside the parking rack 1, and the front wheel slide 2 and the front wheel fixing mechanism 3 are provided on the upper side of the rear wheel fixing mechanism 4 to cover the rear wheel fixing mechanism 4. When the vehicle is not parked, the rear wheel fixing mechanism 4 can be hidden on the lower side of the front wheel slide 2, so that the setting of the rear wheel fixing mechanism 4 will not affect the pushing of the vehicle into the front wheel fixing mechanism 3; when parking is required, after the front wheel of the vehicle is pushed into the front wheel fixing mechanism 3, the front wheel fixing mechanism 3 can move forward with the front wheel slide 2, so that the rear wheel fixing mechanism 4 is exposed, so as to facilitate fixing the rear wheel of the vehicle on the rear wheel fixing mechanism 4, thereby achieving that the front wheel and the rear wheel of the vehicle are both firmly locked.

[0042] By providing the sunken rear wheel fixing mechanism 4, the front wheel fixing mechanism 3 and the rear wheel fixing mechanism 4 can be provided at the same time, and the provision of the rear wheel fixing mechanism 4 will not prevent the vehicle from moving forward into the front wheel fixing mechanism 3, which can make it more convenient to fix the vehicle. Both the front and rear wheels of the vehicle have fixing measures, making it difficult for the vehicle to tip over after being parked.

[0043] It should be noted that when installing the self-weight locking parking device, a groove can be made on the ground to set the parking frame 1 in the groove below the ground, so that the rear wheel fixing mechanism 4 can be completely placed below the ground, and the front wheel slide 2 is located above the rear wheel fixing mechanism 4. The front wheel slide 2 can be set to be flush with the ground to facilitate pushing the vehicle in; of course, other sloped components that are convenient for pushing the cart can also be set at the rear end of the parking frame 1 to facilitate pushing the cart.

[0044] See also Figure 3 , further explained, the front wheel fixing portion 31 includes a fixing seat 311 and a front stop portion 312; the fixing seat 311 is connected to the front end of the front wheel slide 2, the front stop portion 312 is fixedly connected to the front end of the fixing seat 311, and the front wheel flipping portion 32 is rotatably connected to the rear end of the fixing seat 311, and the front wheel flipping portion 32 flips forward and backward toward the direction of the front stop portion 312;

[0045] The upper end of the front stopper 312 is open; the fixing seat 311 , the front stopper 312 and the front wheel flipping portion 32 together form the front wheel accommodating groove 33 .

[0046] By providing the fixing seat 311 and the front stop 312, and the fixing seat 311, the front stop 312, and the front wheel flip portion 32 enclosing the front wheel accommodating groove 33, the front wheel of the vehicle is fixed in the front wheel accommodating groove 33 during parking, which can prevent the vehicle from tipping over during forward movement, and the front stop 312 can be used to prevent the front wheel from shifting forward. This allows the user to move forward without following the vehicle's forward movement during parking, eliminating the need to reserve space for the user to move forward in the deadweight locking parking device, further reducing the width of the deadweight locking parking device.

[0047] See also Figure 3 , further explained, the front barrier portion 312 includes a front barrier bottom plate 3121, a front barrier vertical plate 3122 and a front barrier side plate 3123;

[0048] One end of the front fender bottom plate 3121 is fixedly connected to the end of the fixing seat 311 away from the front wheel flip portion 32, and the other end of the front fender bottom plate 3121 is fixedly connected to the front fender vertical plate 3122, and the front fender vertical plate 3122 is fixedly connected to the upper end surface of the front fender bottom plate 3121. The left and right ends of the front fender bottom plate 3121 are respectively connected to the front fender side plates 3123, and the two front fender side plates 3123 are respectively fixedly connected to the left and right ends of the front fender vertical plate 3122;

[0049] The front fender bottom plate 3121 , the front fender vertical plate 3122 and the two front fender side plates 3123 enclose a first limiting space 3124 , which is communicated with the front wheel accommodating groove 33 so that the front part of the front wheel is confined within the first limiting space 3124 .

[0050] By setting the first limiting space 3124, the front part of the front wheel is limited in the first limiting space 3124 when the vehicle is moving forward, so that the vehicle is not easy to tip over during the moving forward process; wherein, the front vertical plate 3122 can prevent the front wheel of the vehicle from shifting forward, and the front side plate 3123 can prevent the front wheel from shifting in the left and right directions.

[0051] See also Figures 3 and 4 , further explained, the fixing base 311 includes a first bottom plate 3111, a second bottom plate 3112 and a first side plate 3113;

[0052] The first bottom plate 3111, the second bottom plate 3112, and the front fender bottom plate 3121 are sequentially connected along the forward direction of the front wheel slide 2. The first side plate 3113 is connected to the left and right sides of the first bottom plate 3111 and the second bottom plate 3112. The front fender vertical plate 3122 is located at the end of the front fender bottom plate 3121 away from the second bottom plate 3112.

[0053] The second bottom plate 3112 is tilted upward toward the front baffle bottom plate 3121 , and the first bottom plate 3111 is tilted downward toward the second bottom plate 3112 . The angle between the first bottom plate 3111 and the horizontal ground is smaller than the angle between the second bottom plate 3112 and the horizontal ground.

[0054] The first side panel 3113 prevents the front wheel from shifting left and right during vehicle movement, making the front wheel more stable. The second bottom panel 3112 is tilted upward toward the front fender bottom panel 3121, so that when the front wheel is secured in the front wheel receiving groove 33, the second bottom panel 3112 is tangent to the outer circumference of the front wheel, thereby better enclosing and securing the front wheel. The first bottom panel 3111 is tilted downward toward the second bottom panel 3112, which facilitates better securing the front wheel in the front wheel receiving groove 33.

[0055] Specifically, after the front wheel flipping portion 32 flips forward toward the front stopper 312 , the bottom surface of the front end of the front wheel flipping portion 32 abuts against the upper end surface of the first bottom plate 3111 .

[0056] Please participate Figure 4, further explained, the front blocking portion 312 further includes an arc-shaped plate 3125 and a fixed side plate 3126 disposed in the first limiting space 3124;

[0057] The left and right sides of the curved plate 3125 are respectively connected to the fixed side plates 3126. One end of the curved plate 3125 is fixedly connected to the upper end of the front baffle vertical plate 3122. The other end of the curved plate 3125 is fixedly connected to the upper end surface of the second bottom plate 3112, and the bottom surface of the curved plate 3125 is tangent to the second bottom plate 3112. The two ends of the fixed side plates 3126 facing away from each other are respectively fixedly connected to the front baffle side plates 3123. The curved plate 3125 and the two fixed side plates 3126 enclose a second limited space 3127.

[0058] The second limiting space 3127 is communicated with the front wheel accommodating groove 33 so that the front part of the front wheel is limited in the second limiting space 3127 .

[0059] Further explanation is given, the shape of the curved plate 3125 is adapted to the outer shape of the front wheel of the vehicle, and the second limiting space 3127 is used to accommodate the front part of the front wheel. By providing the curved plate 3125 and the fixed side plate 3126, the front part of the front wheel can be conveniently limited inside the second limiting space 3127, thereby preventing the front wheel from shaking in the left and right directions, and helping to improve the stability of fixing the front wheel.

[0060] For further explanation, see Figure 4 and Figure 5 The frame body 11 is provided with movable slots 112 at both ends, and the movable slots 112 are connected to the mounting cavity 111. The front wheel slide 2 is provided with rollers 21 at both ends, and the axes of the rollers 21 are parallel to the horizontal ground. The rollers 21 are slidably connected to the frame body 11 in the movable slots 112. The front wheel slide 2 is also provided with guide wheels 22 at both ends, and the axes of the guide wheels 22 are perpendicular to the horizontal ground. The guide wheels 22 are slidably connected to the frame body 11 in the movable slots 112, and the guide wheels 22 abut against the inner wall of the frame body 11. The rollers 21 allow the front wheel slide 2 to move smoothly along the frame body 11. The guide wheels 22 can guide the front wheel slide 2 to maintain the correct direction during movement, prevent the front wheel slide 2 from deviating during movement, and improve the stability of the front wheel slide 2 during sliding.

[0061] In other embodiments, the front wheel slide 2 may also be slidably connected to the frame body 11 via a slide rail and slider structure.

[0062] See also Figures 4 to 6 , further explained, the front wheel flip portion 32 includes a first flip portion 321, a second flip portion 322 and a first rotating shaft portion 323;

[0063] The first flip portion 321 includes a first flip bottom plate 3211 , and the second flip portion 322 includes a second flip bottom plate 3221 . The first flip bottom plate 3211 and the second flip bottom plate 3221 are connected in a V-shape.

[0064] The first rotating shaft portion 323 includes a first sleeve 3231 and a first rotating shaft 3232. The first sleeve 3231 is fixedly connected between the first flip base plate 3211 and the second flip base plate 3221. The two ends of the first rotating shaft 3232 are respectively fixedly connected to the rear end of the fixed seat 311, and the first sleeve 3231 is sleeved on the outer periphery of the first rotating shaft 3232. The first sleeve 3231 is rotatably connected to the first rotating shaft 3232.

[0065] By arranging the first flip base plate 3211 and the second flip base plate 3221 in a V-shape, the front wheel of the vehicle sequentially presses over the first flip base plate 3211 and the second flip base plate 3221. When the vehicle advances until the center of gravity of the front wheel exceeds the first rotating shaft 3232, the front wheel flip portion 32 is triggered to flip forward, causing the second flip base plate 3221 to flip and be pressed by the front wheel. At this time, the front end of the front wheel abuts against the front stop 312. The contact point between the front stop 312, the first flip portion 321, and the second flip portion 322, as well as the weight of the front wheel, jointly locks the front wheel between the front wheel flip portion 32 and the front wheel fixing portion 31. When the front wheel is moved rearward by human power, the front wheel flip portion 32 flips in the opposite direction as the front wheel is pushed out, thereby unlocking the front wheel.

[0066] In one embodiment, the front end of the front wheel enters the first confined space 3124 and becomes tangent to the front vertical plate 3122. In another embodiment, the front end of the front wheel enters the second confined space 3127 and becomes tangent to the curved plate 3125. The contact points between the front wheel, the curved plate 3125, the first and second flip portions 321, 322, and the weight of the front wheel together lock the front wheel between the front wheel flip portion 32 and the front wheel fixing portion 31.

[0067] Specifically, both ends of the first rotating shaft 3232 are fixedly connected to the two first side plates 3113. After the second flip portion 322 flips forward toward the front stop 312, the bottom surface of the front end of the second flip bottom plate 3221 abuts against the upper end surface of the first bottom plate 3111.

[0068] See also Figure 6 and Figure 7 , further explained, the first flip portion 321 further includes a first flip side plate 3212, the left and right ends of the first flip bottom plate 3211 are respectively connected to the first flip side plates 3212, and the first flip bottom plate 3211 and the first flip side plates 3212 are enclosed to form a first through slot 3213; one side of the first flip side plate 3212 close to the second flip portion 322 is a beveled side;

[0069] The second flip portion 322 further includes a second flip side plate 3222. The left and right ends of the second flip bottom plate 3221 are respectively connected to the second flip side plates 3222. The second flip bottom plate 3221 and the second flip side plates 3222 enclose a second through slot 3223. The first through slot 3213 and the second through slot 3223 are in communication with each other.

[0070] The first flip side panel 3212 is fixedly connected to the second flip side panel 3222 on the same side. The structure of the second flip side panel 3222 is the same as that of the first flip side panel 3212, and the second flip side panel 3222 and the first flip side panel 3212 are symmetrically arranged relative to the first rotating shaft portion 323.

[0071] By providing the first flip side plate 3212 and the second flip side plate 3222, the rear portion of the front wheel can be fixed in the first through slot 3213 and the second through slot 3223, thereby preventing the front wheel from shifting in the left and right directions, and helping to improve the stability of the front wheel fixing mechanism 3 in fixing the front wheel.

[0072] To further illustrate, the distance between the two first flip side panels 3212 gradually increases from bottom to top in a direction perpendicular to the first flip bottom panel 3211. It should be noted that since the second flip side panels 3222 and the first flip side panels 3212 are symmetrically arranged relative to the first rotation axis portion 323, it is understandable that the distance between the two second flip side panels 3222 also gradually increases from bottom to top in a direction perpendicular to the second flip bottom panel 3221.

[0073] By setting the distance between the two first flip side plates 3212 to gradually increase from bottom to top in the height direction, the front wheel flip portion 32 can be adapted to fix the front wheels of different sizes. When the width of the front wheel is small, the front wheel can only abut against the first flip bottom plate 3211 and the second flip bottom plate 3221. When the width of the front wheel is greater than the width of the first flip bottom plate 3211, the front wheel abuts against the first flip side plate 3212 and the second flip side plate 3222 respectively, so that the front wheel flip portion 32 can lock the front wheels of different sizes.

[0074] For further explanation, see Figures 6 and 7 The first flip portion 321 further includes an oblique baffle 3214. The oblique baffles 3214 are symmetrically connected to the side edges of the two first flip side panels 3212 away from the second flip portion 322, and the distance between the two oblique baffles 3214 gradually decreases along the forward direction of the front wheel slide 2. The provision of the oblique baffles 3214, and the gradual decrease in the distance between the two oblique baffles 3214 along the forward direction of the front wheel slide 2, increases the width of the entrance for the front wheel to enter the first through-slot 3213, helping to guide the front wheel smoothly into the first through-slot 3213 and preventing the front wheel from colliding with the side edge of the first flip side panel 3212 due to difficulty in aligning the front wheel with the first through-slot 3213.

[0075] To further illustrate, the weight of the first flip portion 321 is greater than the weight of the second flip portion 322, that is, the flipping of the second flip portion 322 needs to be triggered by the front wheel pressing over, so that the front wheel flip portion 32 can facilitate the vehicle to enter when in use without the need to readjust the front wheel flip portion 32.

[0076] For further explanation, see Figure 7 The front wheel flip part 32 also includes a locking rod 324, which is fixedly arranged on the bottom surface of the first flip part 321, and the two ends of the locking rod 324 extend to the top of the left and right side walls of the frame body 11 respectively; the upper ends of the left and right side walls of the parking rack 1 are respectively provided with locking blocks 113, and the left and right ends of the locking rod 324 are respectively located at the rear ends of the corresponding locking blocks 113, and the horizontal plane position of the highest point of the locking block 113 is higher than the horizontal plane position of the bottom end surface of the locking rod 324.

[0077] By arranging the locking rod 324 and the locking block 113 to cooperate, the locking block 113 is used to fix the front wheel slide 2 to the rear end of the parking frame 1. At this time, the front wheel flip part 32 has not flipped, and the left and right ends of the locking rod 324 are located at the rear end of the locking block 113. When only the front wheel slide 2 is slid, the left and right ends of the locking rod 324 will be supported by the locking block 113, so that the front wheel slide 2 cannot move forward and the front wheel slide 2 is locked, which can prevent the front wheel slide 2 from being accidentally moved and the parking operation cannot be performed quickly when parking is required.

[0078] When the vehicle is parked, the front wheel enters the front wheel turning portion 32 and continues to move forward so that the front wheel turning portion 32 turns over, the locking rod 324 will be displaced as the first turning portion 321 turns upward. After the front wheel turning portion 32 is turned over, the height of the locking rod 324 is higher than the horizontal plane height of the highest point of the locking block 113, and the front wheel slide 2 is continued to move forward, and the locking rod 324 can pass over the locking block 113, thereby completing the unlocking of the front wheel slide 2; when taking the vehicle, the front wheel slide 2 is moved backward until the locking rod 324 moves to the rear of the locking block 113, and the front wheel is disengaged from the front wheel turning portion 32, and the front wheel turning portion 32 turns over backward and causes the locking rod 324 to be locked to the rear end of the locking block 113 again, completing the process of taking the vehicle and relocking the front wheel slide 2 to the rear end of the parking rack 1.

[0079] For further explanation, see Figure 7 The upper end surface of the locking block 113 is provided with a first guiding inclined surface 1131 , and the first guiding inclined surface 1131 is tilted downward along the forward direction of the front wheel slide 2 .

[0080] When the front wheel slide 2 is accidentally moved and the front wheel slide 2 is unlocked (at this time, the front wheel of the vehicle is not fixed on the front wheel fixing mechanism 3), the front wheel flipping part 32 is in a state of not flipping forward. By setting the first guide slope 1131, it is convenient to re-lock the front wheel slide 2. Specifically, by pulling the front wheel slide 2 backward, the locking rod 324 moves backward along the first guide slope 1131. When the locking rod 324 leaves the first guide slope 1131, the front wheel flipping part 32 can fall under the action of gravity, so that the locking rod 324 falls to the rear end of the locking block 113, thereby re-locking the front wheel slide 2.

[0081] For further explanation, see Figure 1 and Figure 4The self-weight parking device also includes a trolley platform 5, which is fixedly connected to the front wheel slide 2, and the trolley platform 5 is located on the rear side of the front wheel flip part 32, and the rear wheel fixing mechanism 4 is located on the lower side of the trolley platform 5; the trolley platform 5 includes a platform body 51, and the upper end surface of the platform body 51 is provided with a trolley inclined surface 511, one end of the trolley inclined surface 511 is connected to the bottom surface of the rear end of the front wheel flip part 32, and the other end of the trolley inclined surface 511 is inclined downward in the direction away from the front wheel flip part 32.

[0082] By providing the cart slope 511, when parking, the user can push the front wheel of the vehicle into the front wheel fixing mechanism 3 through the cart slope 511 to fix the front wheel; when picking up the vehicle, the front wheel can also be pushed away from the front wheel fixing mechanism 3 through the cart slope 511, so that the user can push the cart more smoothly and save effort when parking and picking up the vehicle.

[0083] For further explanation, see Figure 4 The cart platform 5 further includes a buffer block 52 connected to the upper end surface of the platform body 51 and located on the side of the cart inclined surface 511 close to the front wheel flip portion 32. The bottom of the rear end of the front wheel flip portion 32 rests on the buffer block 52. Specifically, the platform body 51 supports the front wheel flip portion 32. At the same time, the provision of the buffer block 52 can further cushion the impact force of the front wheel flip portion 32 on the platform body 51.

[0084] Furthermore, the trolley platform 5 also includes platform handles 53, which are fixedly connected to the upper end surface of the platform body 51 and symmetrically arranged on the left and right ends of the trolley inclined surface 511. The provision of the platform handles 53 improves the maneuverability of the trolley platform 5, and thus the maneuverability of the front wheel slide 2. For example, when the rear wheel securing mechanism 4 needs to be inspected and maintained, the front wheel slide 2 needs to be pulled open. Once the inspection is complete, the front wheel slide 2 can be easily pushed by holding the platform handles 53, so that the front wheel slide 2 re-covers the rear wheel securing mechanism 4. Furthermore, the distance between the two platform handles 53 gradually decreases in the horizontal direction as it approaches the front wheel flip portion 32, thereby increasing the width of the entrance for the front wheel to enter the front wheel flip portion 32 and facilitating smooth entry of the front wheel into the front wheel flip portion 32.

[0085] See also Figures 8 and 9 , further explained, the rear wheel fixing portion 42 further includes a front baffle 421 located in the accommodating cavity 411;

[0086] The lower end of the front baffle 421 is fixedly connected to the bottom of the sunken mounting frame 41 , the upper end of the front baffle 421 is fixedly connected to the upper end of the sunken mounting frame 41 , and the front baffle 421 is tilted upward in a direction away from the rear wheel flip portion 43 .

[0087] By providing the upwardly inclined front fender 421, when the rear wheel enters the rear wheel accommodating groove 44, the outer peripheral wall of the rear wheel can be tangent to the plane of the front fender 421, which can increase the contact area between the rear wheel and the front fender 421 and help to press the rear wheel tightly against the front fender 421.

[0088] For further explanation, see Figures 8 to 10 The rear wheel fixing portion 42 further includes a side fender 422 located within the accommodating cavity 411. One end of the side fender 422 is connected to the front fender 421, and the other end of the side fender 422 extends toward the rear wheel flip portion 43. The upper end surface of the side fender 422 is flush with the upper end surface of the front fender 421. The side fenders 422 are symmetrically connected to the left and right sides of the front fender 421, and the distance between the two side fenders 422 gradually increases in the horizontal direction from the front fender 421 to the rear wheel flip portion 43. The provision of the side fenders 422 and the gradual increase in the distance between the two side fenders 422 from the front fender 421 to the rear wheel flip portion 43 facilitate securing wheels of different sizes between the two side fenders 422.

[0089] See also Figures 8 to 10 , further explained, the rear wheel flip portion 43 includes a third flip portion 431, a fourth flip portion 432 and a second rotation shaft portion 433;

[0090] The third flip portion 431 includes a third flip bottom plate 4311 , and the fourth flip portion 432 includes a fourth flip bottom plate 4321 . The third flip bottom plate 4311 and the fourth flip bottom plate 4321 are connected in a V-shape.

[0091] The second rotating shaft portion 433 includes a second sleeve 4331 and a second rotating shaft 4332. The second sleeve 4331 is fixedly connected between the third flip base plate 4311 and the fourth flip base plate 4321. The two ends of the second rotating shaft 4332 are respectively fixedly connected to the left and right side walls of the sunken mounting frame 41, and the second sleeve 4331 is sleeved on the outer periphery of the second rotating shaft 4332. The second sleeve 4331 is rotatably connected to the second rotating shaft 4332.

[0092] By arranging the third flip bottom plate 4311 and the fourth flip bottom plate 4321 to be connected in a V-shape, the rear wheels of the vehicle press over the third flip bottom plate 4311 and the fourth flip bottom plate 4321 in sequence. When the vehicle moves forward until the center of gravity of the rear wheel exceeds the second rotating shaft 4332, the rear wheel flipping portion 43 can be triggered to flip forward, so that the fourth flip bottom plate 4321 flips and is pressed by the rear wheel. At this time, the front end of the front wheel enters the rear wheel accommodating groove 44 and is tangent to the front baffle 421, and the rear end of the rear wheel is tangent to the third flip bottom plate 4311 and the fourth flip bottom plate 4321.

[0093] The rear wheel is locked by the tangent point between the third flip part 431 and the fourth flip part 432 of the rear wheel and the front fender 421, as well as the weight of the rear wheel, and is locked between the rear wheel fixing part 42, the rear wheel flip part 43 and the sunken mounting frame 41; the rear wheel is moved backward under human power, and the rear wheel flip part 43 can flip in the opposite direction as the rear wheel is pushed out, thereby completing the unlocking of the rear wheel.

[0094] To further illustrate, the weight of the third flip portion 431 is greater than the weight of the fourth flip portion 432, that is, the flipping of the fourth flip portion 432 needs to be triggered by the rear wheel pressing over it. When the rear wheel moves backward to unlock, when the weight of the rear wheel cannot press down the fourth flip portion 432, the rear wheel flip portion 43 flips backward under the action of gravity.

[0095] See also Figures 8 to 10 , further explained, the third flip portion 431 also includes a third flip side plate 4312, the left and right ends of the third flip bottom plate 4311 are respectively connected to the third flip side plates 4312, and the third flip bottom plate 4311 and the third flip side plates 4312 are enclosed to form a third through slot 4313;

[0096] The fourth flip portion 432 further includes a fourth flip side plate 4322 , and the left and right ends of the fourth flip bottom plate 4321 are respectively connected to the fourth flip side plates 4322 , and the fourth flip side plates 4322 are fixedly connected between the third flip side plate 4312 and the fourth flip bottom plate 4321 on the same side;

[0097] A fourth through slot 4323 is formed between the fourth flip bottom plate 4321 and the fourth flip side plate 4322 , and the third through slot 4313 is connected to the fourth through slot 4323 .

[0098] By providing the third flip side plate 4312 and the fourth flip side plate 4322 , the rear wheel can be fixed in the third through slot 4313 and the fourth through slot 4323 , thereby preventing the rear wheel from shifting in the left-right direction and helping to improve the stability of the rear wheel fixing mechanism 4 .

[0099] To further illustrate, the distance between the two third flip side plates 4312 gradually increases from bottom to top in a direction perpendicular to the third flip bottom plate 4311 , so that the rear wheel flip portion 43 can be adapted to fix rear wheels of different sizes.

[0100] For further explanation, see Figure 9 The third flip portion 431 further includes a mounting plate 4314, which is disposed in a one-to-one correspondence with the third flip side plate 4312. One end of the mounting plate 4314 is fixedly connected to the upper side of the third flip side plate 4312, and the other end of the mounting plate 4314 extends outward from the upper and left side walls of the sunken mounting frame 41. The mounting plate 4314 allows the rear wheel flip portion 43 to rest against the upper end of the sunken mounting frame 41 when the rear wheel flip portion 43 flips forward, providing support and preventing the rear wheel flip portion 43 from flipping too far forward.

[0101] For further explanation, see Figures 8 and 9 The rear wheel fixing mechanism 4 also includes a support block 45, which is arranged in the accommodating cavity 411; the third flip bottom plate 4311 is provided with an avoidance through-hole 43111 for the support block 45 to pass through, one end of the support block 45 is fixed to the bottom of the sunken mounting frame 41, and the other end of the support block 45 passes through the avoidance through-hole 43111 and is movably connected to the third flip bottom plate 4311; the avoidance through-hole 43111 is used to allow the third flip bottom plate 4311 to avoid the support block 45 when flipping forward and backward.

[0102] Specifically, the avoidance through-hole 43111 is used to allow the third flip base plate 4311 to avoid the support block 45 when flipping forward and backward. When the rear wheel flipping portion 43 flips forward, the third flip base plate 4311 flips forward until the support block 45 is completely disengaged from the avoidance through-hole 43111. When the rear wheel flipping portion 43 flips backward, the third flip base plate 4311 flips backward, allowing the support block 45 to pass through the avoidance through-hole 43111. By providing the support block 45, when it is necessary to unlock the rear wheel, the rear wheel is moved backward so that it can abut against the support block 45 and move backward, thereby supporting the rear wheel in its backward movement.

[0103] For further explanation, see Figure 9 The support block 45 includes a first support portion 451 and a second support portion 452. One end of the second support portion 452 is fixedly connected to the side wall of the first support portion 451, and the other end of the second support portion 452 extends to the lower side of the third flip base 4311. The upper end surface of the second support portion 452 abuts against the lower end surface of the third flip base 4311. By providing the second support portion 452 and abutting the upper end surface of the second support portion 452 against the lower end surface of the third flip base 4311, the second support portion 452 can support the rear wheel flip unit 43.

[0104] For further explanation, see Figure 9 The upper end of the first support portion 451 is provided with a second guide slope 4511, and the second guide slope 4511 is arranged to be inclined downward in the direction of the rear wheel fixing portion 42. When parking, the rear wheel can move forward along the second guide slope 4511, so that the rear wheel flip portion 43 flips forward and presses the rear wheel flip portion 43. The provision of the first support portion 451 and the second guide slope 4511 can play a role in supporting and guiding the displacement of the rear wheel. When picking up the vehicle, the provision of the second guide slope 4511 allows the rear wheel to move backward along the second guide slope 4511 to facilitate the pushing out of the rear wheel.

[0105] In one embodiment, the front wheel fixing mechanism 3 is fixedly connected to the front wheel slide 2 .

[0106] In other embodiments, the front wheel fixing mechanism 3 can also be configured to be rotatable, that is, the front wheel fixing mechanism 3 is rotatably connected to the front wheel slide 2, see Figure 11 Specifically, the fixing seat 311 of the front wheel fixing part 31 is rotatably connected to the front wheel slide 2, the front stop part 312 is fixedly connected to the fixing seat 311, and the front wheel flipping part 32 is rotatably connected to the fixing seat 311, so that the front wheel flipping part 32 will move along with the movement of the front wheel fixing part 31.

[0107] Since the straight-line distance between the two handlebars of vehicles such as bicycles, electric vehicles, or motorcycles is generally the widest, if the front of the vehicle is placed in a straight line with the body of the vehicle when parked, the width required for a single parking space will be relatively large. When the deadweight locking parking device is installed, the required floor space will also be relatively large, resulting in low space utilization. When the front wheel fixing mechanism 3 moves with the front wheel slide 2 to the front end of the frame body 11, the front wheel fixing mechanism 3 drives the front wheel to swing along the front wheel slide 2, thereby causing the front of the vehicle to be placed at an angle. This reduces the width of the parking space required for the front of the vehicle after parking, further reducing the floor space required for the deadweight locking parking device, and helping to improve parking space utilization.

[0108] For further explanation, see Figures 12 to 13 The front wheel fixing portion 31 also includes a steering shaft 313, one end of the steering shaft 313 is fixedly connected to the bottom surface of the second base plate 3112, and the other end of the steering shaft 313 is rotatably connected to the front wheel slide 2, and the end of the steering shaft 313 away from the second base plate 3112 is tilted downward along the forward direction of the front wheel slide 2, so that the front wheel rotates with the fixing seat 311 to be placed obliquely.

[0109] Specifically, the front stopper 312 and the front wheel flipping portion 32 move in conjunction with the movement of the front wheel fixing portion 31. When the front wheel fixing mechanism 3 moves to the front end of the vehicle frame body 11 along with the front wheel slide 2, the front wheel fixing mechanism 3 drives the front wheel to swing along the front wheel slide 2, thereby causing the front end of the vehicle to be placed at an angle. This reduces the width of the parking space required for the front end of the vehicle after parking, further reducing the floor space required for the deadweight locking parking device and helping to improve parking space utilization.

[0110] Since the front wheel swing axis of a bicycle, motorcycle or electric vehicle is generally arranged to be tilted downward in the forward direction of the front wheel, the present invention arranges the steering shaft 313 to be tilted downward in the forward direction of the front wheel slide 2 so that the front wheel can swing freely left and right; further, the axis of the steering shaft 313 coincides with the axis of the vehicle's front wheel swing axis.

[0111] For further explanation, see Figures 12 to 13 The steering shaft 313 and the second base plate 3112 are arranged perpendicular to each other. This helps to set the steering shaft 313 and make the axis of the steering shaft 313 coincide with the axis of the swing shaft of the front wheel, thereby ensuring the stability and smoothness of the steering.

[0112] For further explanation, see Figures 12 to 13The front wheel carriage 2 includes a carriage body 23 and a boss 24. The boss 24 is connected to the upper end surface of the carriage body 23. The boss 24 has a rotation cavity 241 on its end surface facing the steering shaft 313, which mates with the steering shaft 313. The end of the steering shaft 313, distal from the fixed seat 311, is inserted into the rotation cavity 241 and rotatably connected to the boss 24. The boss 24 improves the stability of the fixed seat 311 during rotation about the front wheel carriage 2. Specifically, the front wheel carriage 2 also includes a rotation bearing 25. The end of the steering shaft 313, distal from the fixed seat 311, is fixedly connected to the inner ring of the rotation bearing 25. The outer ring of the rotation bearing 25 is fixedly connected to the inner circumferential wall of the boss 24 within the rotation cavity 241. Furthermore, the boss 24 and the second base plate 3112 are arranged perpendicular to each other to better accommodate the steering shaft 313. Specifically, the roller 21 and the guide wheel 22 are both arranged on the left and right sides of the slide body 23 .

[0113] For further explanation, see Figure 14 and Figure 15 The parking frame 1 also includes a steering guide rail 12, which is arranged in the installation cavity 111, and the steering guide rail 12 is used to limit the displacement path of the front wheel fixing mechanism 3; the front wheel fixing portion 31 also includes a guide column 314 cooperating with the steering guide rail 12, one end of the guide column 314 is fixedly connected to the bottom end surface of the front stop portion 312, and the other end of the guide column 314 is extended and arranged in the steering guide rail 12 and movably connected to the steering guide rail 12, and the guide column 314 is located in front of the steering shaft 313; the steering guide rail 12 includes a straight section 121 and an oblique section 122 that are connected to each other, and the straight section 121 and the oblique section 122 are arranged in sequence along the length direction of the parking frame 1, and the straight section 121 is arranged in the middle of the frame body 11, one end of the oblique section 122 is connected to the straight section 121, and the other end of the oblique section 122 is obliquely extended toward the side wall direction of the frame body 11.

[0114] By setting the steering guide rail 12 and the guide column 314, the guide column 314 moves along the steering guide rail 12 in the steering guide rail 12, and the steering guide rail 12 can be used to guide and limit the displacement path of the front wheel fixing mechanism 3 and the front wheel slide 2; wherein, the steering guide rail 12 includes the straight line segment 121 and the oblique line segment 122 that are interconnected, and the guide column 314 passes through the straight line segment 121 and the oblique line segment 122 in sequence, while driving the front wheel slide 2 and the front wheel fixing mechanism 3 to pass through the straight line segment 121 and the oblique line segment 122 in sequence. When the guide column 314 passes through the oblique line segment 122, since the oblique line segment 122 is toward the frame itself, The side wall of the frame body 11 is arranged obliquely, forcing the front wheel fixing portion 31 to rotate around the front wheel slide 2. The rotation direction of the front wheel fixing portion 31 is consistent with the oblique direction of the oblique segment 122. As the front wheel slide 2 moves forward, the front wheel fixing portion 31 gradually rotates toward the side wall of the frame body 11 (i.e., the oblique direction of the oblique segment 122), driving the front wheel to swing toward the side wall of the frame body 11, thereby causing the front of the vehicle to be placed obliquely, so that the width of the parking space required for the front of the vehicle is smaller after parking, thereby reducing the floor space required for the self-weight locking parking device, and helping to improve the utilization rate of the parking garage space. Specifically, the guide column 314 is fixedly connected to the bottom surface of the front fender bottom plate 3121.

[0115] To further explain, by simultaneously providing the steering guide rail 12 and the front wheel fixing mechanism 3, when parking, the user pushes the front wheels of the vehicle into the front wheel fixing mechanism 3 and fixes them. The user only needs to apply a forward thrust to the vehicle at the rear end of the vehicle to move the front wheel slide 2 forward. The guide column 314 can then move along the path of the steering guide rail 12, and the vehicle can move forward while the front end of the vehicle swings to an inclined position as the fixing seat 311 rotates.

[0116] For further explanation, see Figure 14 and Figure 15 The steering guide rail 12 further includes an extension section 123, which is connected to the end of the oblique line section 122 away from the straight line section 121, and the extension section 123 and the straight line section 121 are arranged parallel to each other. By providing the extension section 123, it is possible to accommodate the parking of vehicles of different body lengths. During use, after the front of the vehicle moves along the oblique line section 122 and completes the oblique placement of the front of the vehicle, it can continue to move forward along the extension section 123 until the rear wheels of the vehicle can be fixed in the rear wheel fixing mechanism 4, thereby improving the applicability and practicality of the self-weight locking parking device. For further explanation, please refer to Figure 14 and Figure 15The end of the guide post 314 away from the front stop 312 is inclined toward a side wall of the frame body 11, and the inclination direction of the guide post 314 is the same as the oblique extension direction of the oblique line segment 122. The end of the guide post 314 away from the front stop 312 abuts against the inner side wall of the straight line segment 121. By arranging the guide post 314 toward a side wall of the frame body 11 and abutting against the side wall of the straight line segment 121, the guide post 314 can sequentially abut against the side walls of the straight line segment 121, the oblique line segment 122, and the extended segment 123 as it moves along the straight line segment 121 and the oblique line segment 122.

[0117] The inclined guide column 314 can generate a certain friction force when cooperating with the straight section 121, the oblique section 122 and the extended section 123, thereby preventing the guide column 314 from sliding or deviating from the predetermined moving path without the action of external force, thereby playing a self-locking role and ensuring the stable position of the fixed seat 311 and the front wheel slide seat 2.

[0118] The inclined guide column 314 can also better adapt to the inclination angle of the oblique segment 122, ensuring that the guide column 314 always moves along the path of the straight segment 121, the oblique segment 122 and the extended segment 123 during the movement, thereby improving the stability of the guide.

[0119] For further explanation, see Figure 14 and Figure 15 A steel ball 3141 is connected to the end of the guide post 314 away from the front stop 312. The steel ball 3141 abuts against the sidewall of the straight segment 121 in the direction of inclination toward the oblique segment 122. The provision of the steel ball 3141 creates rolling friction between the steel ball 3141 and the steering rail 12, reducing the coefficient of friction. This reduces friction and wear between the guide post 314 and the steering rail 12, thereby extending the service life of the guide post 314 and the steering rail 12.

[0120] To further explain, the guide column 314 and the steel ball 3141 can be fixedly welded, or can be set to a detachable connection, such as a threaded connection (the guide column 314 is provided with an external thread at the end away from the fixing seat 311, and the steel ball 3141 is provided with a threaded hole, and the threaded hole is provided with an internal thread threadedly connected to the external thread, so that the guide column 314 and the steel ball 3141 are threadedly connected). The steel ball 3141 can be easily disassembled and replaced. When the steel ball 3141 is severely worn and needs to be replaced, only the steel ball 3141 can be replaced without replacing the guide column 314, which helps to reduce costs.

[0121] For further explanation, see Figure 14 The slide body 23 defines a guide hole 231 that mates with the guide post 314. The end of the guide post 314, which is distal to the front stop 312, passes through the guide hole 231 and is slidably connected to the steering rail 12. By providing the guide hole 231, when the guide post 314 moves along the steering rail 12, the guide post 314 can simultaneously move along the guide hole 231, thereby facilitating the rotation of the front wheel securing mechanism 3 about the front wheel slide 2.

[0122] Furthermore, the guide hole 231 is an arc-shaped through hole. When the front wheel fixing mechanism 3 rotates along the front wheel slide 2, the swing path of the guide post 314 is a circular motion with the connection point between the steering shaft 313 and the second base plate 3112 as the center and the line connecting the center of the circle to the end of the guide post 314 away from the front stop 312 as the radius. By setting the guide hole 231 as an arc-shaped through hole, the shape of the guide hole 231 can be adapted to the movement path of the guide post 314, further limiting the rotational displacement of the front wheel fixing mechanism 3 and improving the stability of the front wheel fixing mechanism 3 during rotation. The above description is only a preferred embodiment of the present invention and does not limit the scope of the present invention. All equivalent structural changes made by using the contents of the present specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields, are included in the scope of patent protection of the present invention.
