[0039] See also Figures 1 to 5 In order to solve the above technical problems, the present invention proposes a front-end inclined parking rack, comprising: a parking rack 1, a front wheel slide 2 and a steering mechanism 3;

[0040] The parking rack 1 includes a frame body 11, the frame body 11 is provided with a mounting cavity 111, the front wheel slide seat 2 is slidably disposed in the mounting cavity 111, and the steering mechanism 3 is rotatably connected to the front wheel slide seat 2; the front wheel slide seat 2 drives the steering mechanism 3 to slide forward and backward along the frame body 11;

[0041] The steering mechanism 3 includes a steering seat 31 and a steering shaft 32;

[0042] The steering seat 31 is provided with a front wheel receiving groove 311 for receiving the front wheel of the vehicle;

[0043] One end of the steering shaft 32 is fixedly connected to the bottom surface of the steering seat 31, and the other end of the steering shaft 32 is rotatably connected to the front wheel slide 2, and the steering shaft 32 is located at the front end of the steering seat 31; the end of the steering shaft 32 away from the steering seat 31 is tilted downward along the forward direction of the front wheel slide 2, and the front wheel swings with the rotation of the steering seat 31 until the front of the vehicle is placed obliquely.

[0044] 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 and the body of the vehicle are placed in a straight line when parked, the width required for a single parking space will be larger, that is, when the front-end inclined parking rack is set up, the required floor space will also be larger, resulting in low space utilization.

[0045] By setting the steering mechanism 3, when the front wheel slide 2 slides to the front end of the parking rack 1, the steering mechanism 3 will move to the front end of the parking rack 1 together with the front wheel slide 2. At the same time, the steering mechanism 3 drives the front wheel to swing along the front wheel slide 2, so that the front of the vehicle is finally placed diagonally, so that the width of the parking space required by the front of the vehicle after parking is smaller, thereby reducing the floor space required for setting up the diagonal parking rack for the front of the vehicle, which helps to improve space utilization and solve the problem in the prior art that the front of the vehicle and the body of the vehicle are placed in a straight line when parking, resulting in a large width required for a single parking space, a large overall floor space, and low space utilization.

[0046] It should be noted that, since the front wheel swing axis of a bicycle, a two-wheeled motorcycle or a two-wheeled electric vehicle is generally arranged to be tilted downward in the forward direction of the front wheel, the present invention arranges the steering shaft 32 to be tilted downward in the forward direction of the front wheel slide 2, so that the rotation axis of the steering shaft 32 is also arranged to be tilted downward in the forward direction of the front wheel slide 2, so that the rotation axis of the steering shaft 32 can be adapted to the rotation axis of the front wheel swing axis of the vehicle. At the same time, the steering shaft 32 is arranged at the front end of the steering seat 31, so that the front wheel of the vehicle can swing freely left and right along the front wheel slide 2.

[0047] See also Figures 2 to 3 , further explained, the steering seat 31 includes a first bottom plate 312, a second bottom plate 313, a first side plate 314 and a front stopper 315;

[0048] The first bottom plate 312, the second bottom plate 313 and the front stopper 315 are sequentially connected along the forward direction of the front wheel slide 2, the first side plate 314 is connected to the left and right sides of the first bottom plate 312 and the second bottom plate 313, and the first bottom plate 312, the second bottom plate 313, the first side plate 314 and the front stopper 315 enclose the front wheel accommodating groove 311;

[0049] The second bottom plate 313 is tilted upward toward the front stopper 315 , and the steering shaft 32 is fixedly connected to the bottom surface of the second bottom plate 313 .

[0050] The front wheel receiving groove 311 is formed by enclosing the first bottom plate 312, the second bottom plate 313, the first side plate 314 and the front stopper 315. The front wheel is fixed in the front wheel receiving groove 311, so that the front wheel can move forward and swing left and right with the steering seat 31 without falling off the steering seat 31. The placement of the front wheel is more stable, which helps to improve the stability of the vehicle when it is parked. The size of the front wheel receiving groove 311 can also be set according to the size of the front wheel of the vehicle, so that the parking space can be used more reasonably.

[0051] To further illustrate, by arranging the second bottom plate 313 to be tilted upward in the forward direction of the front wheel slide 2, when the front wheel is fixed in the front wheel accommodating groove 311, the second bottom plate 313 is tangent to the outer circumference of the front wheel, so as to better surround and fix the front wheel.

[0052] For further explanation, see Figures 2 to 3 The first bottom plate 312 is tilted upward at one end away from the second bottom plate 313, so that an angle (an obtuse angle) is formed between the first bottom plate 312 and the second bottom plate 313, and the angle between the first bottom plate 312 and the horizontal ground is smaller than the angle between the second bottom plate 313 and the horizontal ground, which can facilitate better fixing of the front wheel in the front wheel accommodating groove 311.

[0053] See also Figures 2 to 3 , further explained, the front barrier portion 315 includes a front barrier bottom plate 3151, a front barrier vertical plate 3152 and a front barrier side plate 3153, one end of the front barrier bottom plate 3151 is fixedly connected to an end of the second bottom plate 313 away from the first bottom plate 312, the other end of the front barrier bottom plate 3151 is fixedly connected to the front barrier vertical plate 3152, and the front barrier vertical plate 3152 is fixedly connected to the upper end surface of the front barrier bottom plate 3151, the front barrier bottom plate 3151 The left and right ends are respectively connected to the front fender side panels 3153, and the two front fender side panels 3153 are respectively fixedly connected to the left and right ends of the front fender vertical panel 3152, and the front fender bottom panel 3151, the front fender vertical panel 3152 and the two front fender side panels 3153 enclose a first limiting space 3154, and the first limiting space 3154 is communicated with the front wheel accommodating groove 311 so that the front part of the front wheel is limited in the first limiting space 3154.

[0054] The front fender bottom plate 3151, the front fender vertical plate 3152 and the front fender side plate 3153 are provided to help improve the stability of the front wheels of the fixed vehicle. When parking, the front wheels of the vehicle are pushed into the front wheel accommodating groove 311 and the first limiting space 3154 for limiting and fixing, so that the vehicle is not easy to tip over during the whole pushing process. That is, when parking, the user does not need to follow the forward movement of the vehicle. When the front oblique parking rack is applied to a parking garage, the setting distance between multiple front oblique parking racks can be further reduced, thereby improving the space utilization rate of the parking garage.

[0055] See also Figure 3 , further illustrating, the steering shaft 32 and the second bottom plate 313 are arranged perpendicular to each other.

[0056] Further, the axis of the swing shaft of the front wheel is perpendicular to the second base plate 313. By setting the steering shaft 32 to be perpendicular to the second base plate 313, it is helpful to set the steering shaft 32 and make the axis of the steering shaft 32 coincide with the axis of the swing shaft of the front wheel, thereby ensuring the stability and smoothness of steering.

[0057] To further explain, the axis of the steering shaft 32 coincides with the axis of the front wheel swing axis of the vehicle, so that the front wheel can swing smoothly left and right along with the rotation of the steering mechanism 3.

[0058] See also Figure 3 , further explained, the front wheel slide 2 includes a slide body 21 and a boss 22, the upper end surface of the slide body 21 is connected to the boss 22, the end surface of the boss 22 facing the steering seat 31 is provided with a rotating cavity 221 that cooperates with the steering shaft 32, and the end of the steering shaft 32 away from the steering seat 31 is inserted into the rotating cavity 221 and is rotatably connected to the boss 22.

[0059] By providing the protruding column 22, the stability of the steering seat 31 when rotating around the front wheel slide seat 2 can be improved. Figure 3 The front wheel slide seat 2 also includes a rotating bearing 23, and one end of the steering shaft 32 away from the steering seat 31 is fixedly connected to the inner ring of the rotating bearing 23, and the outer ring of the rotating bearing 23 is fixedly connected to the inner circumferential wall of the boss 22 in the rotating cavity 221.

[0060] For further explanation, see Figure 3 The boss 22 and the second bottom plate 313 are arranged perpendicular to each other to better fit the steering shaft 32 .

[0061] In other embodiments, see Figures 4 to 6The front-end oblique parking rack can also be provided with a front wheel fixing mechanism 5 to further firmly fix the front wheel of the vehicle. The front wheel fixing mechanism 5 includes a front wheel fixing portion 51 and a front wheel flipping portion 52, wherein the front wheel fixing portion 51 is fixedly connected to the front end of the steering mechanism 3, and the front wheel flipping portion 52 is rotatably connected to the rear end of the steering mechanism 3, and the front wheel flipping portion 52 can flip forward and backward along the direction of the front wheel fixing portion 51; the front wheel fixing portion 51 and the front wheel flipping portion 52 cooperate to fix the front wheel; by simultaneously providing the steering guide rail 12 and the front wheel fixing mechanism 5, when parking, the user pushes the front wheel of the vehicle into the front wheel fixing mechanism 5 and fixes it, and the user only needs to apply a forward thrust to the vehicle at the rear end of the vehicle, so that the front wheel slide seat 2 moves forward, and the guide column 316 can move along the path of the steering guide rail 12, and realize that the front of the vehicle moves forward and the front of the vehicle swings to an oblique position with the rotation of the steering seat 31. When parking, the user does not need to move forward following the movement of the vehicle. When the front-end tilted parking rack is applied to a parking garage, the setting distance between multiple front-end tilted parking racks can be further reduced, thereby improving the space utilization rate of the parking garage.

[0062] For further explanation, see Figure 6 The front wheel fixing part 51 is arranged in the front wheel accommodating groove 311, and one end of the front wheel fixing part 51 is fixedly connected to the front stopper 315, and the other end of the front wheel fixing part 51 is fixedly connected to the upper end surface of the second bottom plate 313. The end surface of the front wheel fixing part 51 away from the front stopper 315 is provided with a second limiting space 511 for accommodating the front part of the front wheel, and the upper end of the front wheel fixing part 51 is open. The second limiting space 511 is adapted to the shape of the front wheel of the vehicle, and the second limiting space 511 is provided for accommodating the front section of the front wheel to achieve the fixing of the front wheel.

[0063] For further explanation, see Figure 6The front wheel fixing part 51 includes an arc plate 512 and a fixed side plate 513. The fixed side plates 513 are connected to the left and right sides of the arc plate 512 respectively. One end of the arc plate 512 is fixedly connected to the upper end of the front fender vertical plate 3152. The other end of the arc plate 512 is fixedly connected to the upper end surface of the second bottom plate 313, and the bottom surface of the arc plate 512 is tangent to the second bottom plate 313. The end surfaces of the two fixed side plates 513 that are separated from each other are fixedly connected to the front fender side plates 3153 respectively. The arc plate 512 and the two fixed side plates 513 enclose the second limiting space 511. By providing the arc plate 512 and the fixed side plates 513, it is convenient to limit the front part of the front wheel in the second limiting space 511, so as to prevent the front wheel from shaking in the left and right directions and improve the stability of fixing the front wheel. Further explained, the front block portion 315 also includes a support plate, which is arranged in the first limiting space 3154, and one end of the support plate is fixedly connected to the front block vertical plate 3152, and the other end of the support plate is fixedly connected to the arc plate 512, and the end of the support plate facing away from the front block vertical plate 3152 is provided with an arc surface matching the shape of the arc plate 512, and by setting the support plate, the arc plate 512 can be supported.

[0064] For further explanation, see Figure 6 to Figure 7The front wheel flip part 52 includes a first flip part 521, a second flip part 522 and a first rotating shaft part 523; the first flip part 521 includes a first flip bottom plate 5211, the second flip part 522 includes a second flip bottom plate 5221, and the first flip bottom plate 5211 and the second flip bottom plate 5221 are connected in a V shape; the first rotating shaft part 523 includes a first sleeve 5231 and a first rotating shaft 5232, the first sleeve 5231 is fixedly connected between the first flip bottom plate 5211 and the second flip bottom plate 5221, the two ends of the first rotating shaft 5232 are respectively fixedly connected to the two first side plates 314, and the first sleeve 5231 is sleeved on the outer periphery of the first rotating shaft 5232, and the first sleeve 5231 is rotatably connected to the first rotating shaft 5232. By arranging the first flip bottom plate 5211 and the second flip bottom plate 5221 to be connected in a V shape, the front wheel of the vehicle can press over the first flip bottom plate 5211 and the second flip bottom plate 5221 in sequence. When the vehicle moves forward until the center of gravity of the front wheel exceeds the first rotating shaft 5232, the front wheel flipping part 52 can be triggered to flip forward, so that the second flip bottom plate 5221 is flipped until it is pressed by the front wheel. At this time, the front end of the front wheel enters the second limiting space 511 and is tangent to the arc plate 512, and the rear end of the front wheel is tangent to the first flip bottom plate 5211 and the second flip bottom plate 5221. The front wheel is locked by the tangent points where the front wheel abuts against the arc plate 512, the first flipping part 521 and the second flipping part 522, and the weight of the front wheel, and the front wheel is locked between the front wheel flipping part 52, the front wheel fixing part 51 and the steering seat 31; the front wheel is moved backward under human power, and the front wheel flipping part 52 can flip in the opposite direction as the front wheel is pushed out, thereby completing the unlocking of the front wheel.

[0065] For further explanation, see Figure 7The first flip portion 521 further includes a first flip side plate 5212, the left and right ends of the first flip bottom plate 5211 are respectively connected to the first flip side plate 5212, and the first flip bottom plate 5211 and the first flip side plate 5212 are enclosed to form a first through groove 5213; one side edge of the first flip side plate 5212 close to the second flip portion 522 is a hypotenuse; the second flip portion 522 further includes a second flip side plate 5222, the left and right ends of the second flip bottom plate 5221 are respectively connected to the second flip side plate 5222, and the first through groove 5213 is enclosed between the first flip bottom plate 5211 and the first flip side plate 5212. The first through slot 5213 and the second through slot 5223 are connected to each other; the first through slot 5213 and the second through slot 5223 are connected to each other; the first flip side plate 5212 is fixedly connected to the second flip side plate 5222 on the same side; the structure of the second flip side plate 5222 is the same as that of the first flip side plate 5212, and the second flip side plate 5222 and the first flip side plate 5212 are symmetrically arranged relative to the first rotating shaft portion 523. By arranging the first flip side plate 5212 and the second flip side plate 5222, the front wheel can be fixed in the first through slot 5213 and the second through slot 5223, so as to prevent the front wheel from shifting in the left-right direction, which helps to improve the stability of the front wheel fixing mechanism 5.

[0066] For further explanation, see Figure 7 , the distance between the two first flip side plates 5212 gradually increases from bottom to top in a direction perpendicular to the first flip bottom plate 5211. Since the second flip side plate 5222 and the first flip side plate 5212 are symmetrically arranged relative to the first rotating shaft portion 523, it can be understood that the distance between the two second flip side plates 5222 also gradually increases from bottom to top in a direction perpendicular to the second flip bottom plate 5221. By setting the distance between the two first flip side plates 5212 to gradually increase from bottom to top in the height direction, the front wheel flipping portion 52 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 5211 and the second flip bottom plate 5221. When the width of the front wheel is greater than the width of the first flip bottom plate 5211, the front wheel abuts against the first flip side plate 5212 and the second flip side plate 5222 respectively, so that the front wheel flipping portion 52 can lock the front wheels of different sizes.

[0067] For further explanation, see Figure 7The first flip part 521 further includes an oblique baffle 5214, and the two first flip side plates 5212 are symmetrically connected to the oblique baffles 5214 on one side away from the second flip part 522, and the distance between the two oblique baffles 5214 gradually decreases along the forward direction of the front wheel slide 2. By providing the oblique baffles 5214, and the distance between the two oblique baffles 5214 gradually decreases along the forward direction of the front wheel slide 2, the width of the entrance of the front wheel into the first through slot 5213 is made larger, which helps to guide the front wheel to smoothly enter the first through slot 5213, and avoids the front wheel from colliding with the side of the first flip side plate 5212 due to the difficulty of the front wheel to align with the first through slot 5213. To further explain, the weight of the first flip part 521 is greater than the weight of the second flip part 522, that is, the flipping of the second flip part 522 needs to be triggered by the front wheel pressing over, so that the front wheel flip part 52 can facilitate the entry of the vehicle when in use, and there is no need to readjust the front wheel flip part 52.

[0068] For further explanation, see Figures 4 to 7 The front wheel flipping part 52 also includes a locking rod 524, which is fixedly arranged on the bottom surface of the first flipping part 521, and the two ends of the locking rod 524 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 524 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 524. By setting the locking rod 524 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 flipping part 52 has not flipped, and the left and right ends of the locking rod 524 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 524 will be resisted 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.

[0069] When parking, when a vehicle enters, the front wheel enters the front wheel flipping portion 52 and continues to move forward to make the front wheel flipping portion 52 flip over, the locking rod 524 will be displaced as the first flipping portion 521 flips upward. After the front wheel flipping portion 52 is flipped over, the position height of the locking rod 524 is higher than the horizontal plane position height of the highest point of the locking block 113, and the front wheel slide 2 continues to move forward, and the locking rod 524 can pass over the locking block 113, thereby completing the unlocking of the front wheel slide 2; when picking up the car, the front wheel slide 2 is moved backward until the locking rod 524 moves to the rear of the locking block 113, and the front wheel is disengaged from the front wheel flipping portion 52, and the front wheel flipping portion 52 flips backward and makes the locking rod 524 re-locked to the rear end of the locking block 113, completing the picking up of the car and re-locking the front wheel slide 2 at the rear end of the parking rack 1.

[0070] 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 arranged to be inclined downward along the advancing direction of the front wheel slide 2. 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 5), at this time, the front wheel flipping part 52 is in a state of not flipping forward, and the first guiding inclined surface 1131 can be arranged to facilitate the re-locking of the front wheel slide 2. Specifically, by pulling the front wheel slide 2 backward, the locking rod 524 moves backward along the first guiding inclined surface 1131, and when the locking rod 524 leaves the first guiding inclined surface 1131, the front wheel flipping part 52 can fall under the action of gravity, so that the locking rod 524 falls to the rear end of the locking block 113, and the front wheel slide 2 is re-locked.

[0071] During the process of moving the front wheel slide 2 backward, the locking rod 524 can move backward along the first guide slope 1131. When the locking rod 524 leaves the locking slope, the front wheel flipping part 52 can automatically flip under the action of gravity, so that the locking rod 524 is re-locked at the rear end of the locking block 113, thereby re-locking the front wheel slide 2.

[0072] See also Figures 8 to 9 , further explained, the parking rack 1 also includes a steering guide rail 12, the steering guide rail 12 is arranged in the installation cavity 111, and the steering guide rail 12 is used to limit the displacement path of the steering seat 31;

[0073] The steering seat 31 further includes a guide column 316 matched with the steering guide rail 12, one end of the guide column 316 is fixedly connected to the bottom end surface of the steering seat 31, the other end of the guide column 316 is extended and arranged in the steering guide rail 12 and movably connected to the steering guide rail 12, and the guide column 316 is located in front of the steering shaft 32;

[0074] The turning guide rail 12 includes a straight segment 121 and an oblique segment 122 which are interconnected. The straight segment 121 and the oblique segment 122 are arranged in sequence along the length direction of the parking frame 1, and the straight segment 121 is arranged in the middle of the frame body 11, one end of the oblique segment 122 is connected to the straight segment 121, and the other end of the oblique segment 122 is obliquely extended toward a side wall of the frame body 11.

[0075] By setting the steering guide rail 12 and the guide column 316, the guide column 316 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 steering seat 31; 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 316 passes through the straight line segment 121 and the oblique line segment 122 in sequence, and at the same time drives the front wheel slide 2 and the front wheel fixing mechanism 5 to pass through the straight line segment 121 and the oblique line segment 122 in sequence, when the When the guide column 316 passes through the oblique line segment 122, since the oblique line segment 122 is obliquely arranged toward the side wall of the frame body 11, the steering seat 31 is forced to rotate around the front wheel slide 2, and the rotation direction of the steering seat 31 is consistent with the oblique setting direction of the oblique line segment 122, so that during the forward movement of the front wheel slide 2, the steering seat 31 gradually rotates toward the side wall of the frame body 11 (that is, the oblique setting direction of the oblique line segment 122), driving the front wheel to swing toward the side wall of the frame body 11 (see Figure 5 , Figure 5 The front wheel slide 2 is a schematic diagram of the state after the steering mechanism 3 and the front wheel fixing mechanism 5 complete the steering when the front wheel slide 2 slides to the front end of the frame body 11, so that the front of the vehicle is placed obliquely, so that the width of the parking space required by the front of the vehicle is smaller after the vehicle is parked, thereby reducing the floor space required for the oblique front parking rack, which helps to improve space utilization. Specifically, the guide column 316 is fixedly connected to the bottom surface of the front stop 315.

[0076] Specifically, see Figure 3 The guide column 316 is connected to the bottom end surface of the front barrier bottom plate 3151 .

[0077] In other embodiments, the front-of-vehicle inclined parking rack may also be provided with a drive motor, the drive end of the drive motor is connected to the steering shaft 32, and the drive motor is used to drive the steering shaft 32 to rotate around the front wheel slide 2, so that the front wheel rotates with the steering seat 31 until the front of the vehicle is placed obliquely.

[0078] See also Figures 8 to 9 , further explained, the turning guide rail 12 also includes an extension section 123, the extension section 123 is connected to one 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.

[0079] By providing the extension section 123, it is possible to accommodate the parking of vehicles with different body lengths. When in use, after the front of the vehicle moves along the oblique section 122 and completes the oblique placement of the front of the vehicle, it can continue to move forward along the extension section 123, thereby improving the applicability and practicality of the oblique front parking rack.

[0080] See also Fig. 9 , further illustrating that one end of the guide column 316 away from the steering seat 31 is inclined toward a side wall of the frame body 11, and the inclination direction of the guide column 316 is the same as the oblique extension direction of the oblique line segment 122; one end of the guide column 316 away from the steering seat 31 is in contact with the inner side wall of the straight line segment 121.

[0081] By setting the guide column 316 to be inclined toward a side wall of the frame body 11, and the guide column 316 abuts against the side wall of the straight segment 121, the guide column 316 can abut against the side walls of the straight segment 121, the oblique segment 122 and the extended segment 123 in sequence when moving along the straight segment 121 and the oblique segment 122.

[0082] The inclined guide column 316 can generate a certain friction force when cooperating with the straight segment 121, the oblique segment 122 and the extended segment 123, thereby preventing the guide column 316 from sliding or deviating from the predetermined moving path without the influence of external force, thereby playing a self-locking role and ensuring the stable position of the steering seat 31 and the front wheel slide seat 2.

[0083] The inclined guide column 316 can also better adapt to the inclination angle of the oblique line segment 122, ensuring that the guide column 316 always moves along the path of the straight line segment 121, the oblique line segment 122 and the extended segment 123 during the movement, thereby improving the stability of the guidance.

[0084] For further explanation, see Fig. 9The end of the guide column 316 away from the steering seat 31 is connected with a steel ball 3161, and the steel ball 3161 abuts against the side wall of the straight line segment 121 in the inclination direction of the oblique line segment 122. By providing the steel ball 3161, rolling friction is formed between the steel ball 3161 and the steering guide rail 12, which can reduce the friction coefficient, thereby reducing the friction and wear between the guide column 316 and the steering guide rail 12, and extending the service life of the guide column 316 and the steering guide rail 12.

[0085] Further explanation: the guide column 316 and the steel ball 3161 can be fixedly welded, or can be arranged to be detachably connected, such as a threaded connection (the guide column 316 is provided with an external thread at the end away from the steering seat 31, and the steel ball 3161 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 316 and the steel ball 3161 are threadedly connected). The steel ball 3161 can be easily disassembled and replaced. When the steel ball 3161 is severely worn and needs to be replaced, only the steel ball 3161 can be replaced without replacing the guide column 316, which helps to reduce costs.

[0086] See also Figure 3 and Fig. 9 , further explained, the front wheel slide seat 2 is provided with a guide hole 211 that matches the guide column 316 , and the end of the guide column 316 away from the steering seat 31 passes through the guide hole 211 and is slidably connected to the steering guide rail 12 .

[0087] By providing the guide hole 211 , when the guide post 316 moves along the steering guide rail 12 , the guide post 316 can simultaneously move along the guide hole 211 , so that the steering seat 31 can rotate around the front wheel slide seat 2 .

[0088] Specifically, the guide hole 211 is opened on the upper end surface of the slide body 21 .

[0089] See also Figure 3 , further explained, the guide hole 211 is an arc-shaped through hole. Since when the steering mechanism 3 rotates along the front wheel slide 2, the swing path of the guide column 316 is a circular motion with the connection point between the steering shaft 32 and the steering seat 31 as the center and the line from the center to the end of the guide column 316 away from the steering seat 31 as the radius, by setting the guide hole 211 as an arc-shaped through hole, the shape of the guide hole 211 can be adapted to the moving path of the guide column 316, which plays a role in further limiting the rotation displacement of the steering seat 31 and improving the stability of the steering seat 31 when rotating.

[0090] See also Figure 6and Fig. 9 , further explained, the left and right ends of the frame body 11 are provided with movable slide grooves 112, and the movable slide grooves 112 are communicated with the mounting cavity 111; the left and right ends of the front wheel slide seat 2 are respectively provided with rollers 212, and the axes of the rollers 212 are parallel to the horizontal ground, and the rollers 212 are slidably connected with the frame body 11 in the movable slide grooves 112.

[0091] By providing the roller 212 , the front wheel slide 2 can move smoothly along the frame body 11 .

[0092] Further, guide wheels 213 are provided at the left and right ends of the front wheel slide 2, respectively, and the axis of the guide wheel 213 is perpendicular to the horizontal ground. The guide wheel 213 is slidably connected with the frame body 11 in the movable slide groove 112, and the guide wheel 213 abuts against the inner wall surface of the frame body 11. By providing the guide wheels 213, the front wheel slide 2 can be guided to maintain the correct direction during the movement, and the front wheel slide 2 can be prevented from being offset during the movement, thereby improving the stability of the front wheel slide 2 when sliding.

[0093] In other embodiments, see Figure 5 , Fig.10 and Fig.11 The front-end inclined parking rack also includes a rear wheel fixing mechanism 4, which is fixedly arranged at the rear end of the installation cavity 111, and the rear wheel fixing mechanism 4 is located at the lower side of the front wheel slide seat 2; the rear wheel fixing mechanism 4 is used to fix the rear wheel of the vehicle.

[0094] The rear wheel fixing mechanism 4 includes a sunken mounting frame 41 and a rear wheel fixing portion 42 and a rear wheel flipping portion 43 installed on the sunken mounting frame 41; the sunken mounting frame 41 is arranged in the mounting cavity 111, and the sunken mounting frame 41 is located at the lower side of the front wheel slide 2; the sunken mounting frame 41 is provided with a accommodating cavity 411, and the accommodating cavity 411 is used to install the rear wheel fixing portion 42 and the rear wheel flipping portion 43; the rear wheel fixing portion 42 is fixedly arranged at the front end of the sunken mounting frame 41, and the rear wheel flipping portion 43 is rotatably arranged at the rear end of the sunken mounting frame 41; the rear wheel flipping portion 43 flips forward and backward in the direction of the rear wheel fixing portion 42, and a rear wheel accommodating groove 44 for fixing the rear wheel is formed between the rear wheel fixing portion 42 and the rear wheel flipping portion 43.

[0095] By arranging the sunken installation frame 41 in the installation cavity 111, the rear wheel fixing mechanism 4 can be hidden inside the parking rack 1 (see Figure 5 , Fig.10 and Fig.11 ), the front wheel slide 2 and the front wheel fixing mechanism 5 are provided on the upper side of the rear wheel fixing mechanism 4 to cover the rear wheel fixing mechanism 4. When parking is required, the rear wheel fixing mechanism 4 can be used to fix the rear wheel of the vehicle after the front wheel slide 2 is removed. It should be noted that when installing the parking rack 1, a groove can be made on the ground to set the parking rack 1 in the groove, so that the sunken installation frame 41 is completely below the ground, and the front wheel slide 2 is located above the sunken installation frame 41. 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 rack 1 to facilitate pushing the cart.

[0096] By setting the sunken rear wheel fixing mechanism 4, the front wheel fixing mechanism 5 and the rear wheel fixing mechanism 4 can be set at the same time, so as to solve the problem that the setting of the rear wheel fixing mechanism 4 will block the vehicle from moving forward to the front wheel fixing mechanism 5 for fixing, and the vehicle can be fixed more conveniently. In addition, the front and rear wheels of the vehicle are both fixed, so that the vehicle is not easy to tip over after being parked.

[0097] For further explanation, see Fig.11 By providing the rear wheel flipping part 43, after the rear wheel flipping part 43 flips forward, a rear wheel receiving groove 44 for fixing the rear wheel is formed between the rear wheel fixing part 42 and the rear wheel flipping part 43, so that the vehicle can be locked in the rear wheel receiving groove 44 by the dead weight of the rear wheel. Specifically, when the rear wheel enters the rear wheel fixing mechanism 4, the rear wheel first presses over the rear wheel flipping part 43 and then enters the rear wheel receiving groove 44 to be fixed. During the entry process, the rear wheel flips the rear wheel flipping part 43 forward, so that the front and rear ends of the rear wheel are respectively in contact with the rear wheel fixing part 42 and the rear wheel flipping part 43, so as to achieve the dead weight locking of the rear wheel.

[0098] By arranging the rear wheel fixing portion 42 and the rear wheel flipping portion 43 in the sunken installation frame 41, the structure of the rear wheel fixing mechanism 4 is made more compact. During installation, the rear wheel fixing portion 42 and the rear wheel flipping portion 43 can be assembled with the sunken installation frame 41 at other places first, and then installed in the installation cavity 111 of the frame body 11, thereby reducing the time for on-site assembly and improving the efficiency of installation.

[0099] By simultaneously providing the steering rail 12, the front wheel fixing mechanism 5 and the rear wheel fixing mechanism 4, when parking, the user pushes the front wheel of the vehicle into the front wheel fixing mechanism 5 and fixes it. 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, and the guide column 316 can move along the path of the steering rail 12, and the front of the vehicle can be swung to an oblique position with the rotation of the steering seat 31 while the vehicle moves forward, until the rear wheel of the vehicle is fixed in the rear wheel fixing mechanism 4. When parking, the user does not need to move forward following the forward movement of the vehicle. When the front oblique parking rack is applied to a parking garage, the setting distance between multiple front oblique parking racks can be further reduced. In addition, the parking and fixing of the vehicle does not need to be supported by the vehicle's own tripod, and the front oblique parking rack does not need to reserve a position for the vehicle to put down its tripod, thereby reducing the width of the front oblique parking rack and improving the space utilization rate of the parking garage.

[0100] For further explanation, see Figure 12 to Figure 14 The rear wheel fixing portion 42 includes a front baffle 421 located in the accommodating cavity 411; the lower end of the front baffle 421 is fixedly connected to the bottom of the sunken installation frame 41, the upper end of the front baffle 421 is fixedly connected to the upper end of the sunken installation frame 41, and the front baffle 421 is arranged to be inclined upward in a direction away from the rear wheel flipping portion 43. By providing the upwardly inclined front baffle 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 baffle 421, which can increase the contact area between the rear wheel and the front baffle 421, and help to press the rear wheel tightly against the front baffle 421.

[0101] For further explanation, see Figure 12 to Figure 14 The rear wheel fixing portion 42 further includes a side baffle 422 located in the accommodating cavity 411, one end of the side baffle 422 is connected to the front baffle 421, and the other end of the side baffle 422 is extended in the direction of the rear wheel flipping portion 43, and the upper end surface of the side baffle 422 is flush with the upper end surface of the front baffle 421; the left and right sides of the front baffle 421 are symmetrically connected with the side baffles 422, and the distance between the two side baffles 422 gradually increases from the front baffle 421 to the horizontal direction of the rear wheel flipping portion 43. By providing the side baffles 422, and the distance between the two side baffles 422 gradually increases from the front baffle 421 to the rear wheel flipping portion 43, the wheel enters the cavity 411, and it also helps to fix wheels of different sizes between the two side baffles 422.

[0102] For further explanation, see Figure 12 to Figure 14 The rear wheel flip part 43 includes a third flip part 431, a fourth flip part 432 and a second rotating shaft part 433; the third flip part 431 includes a third flip bottom plate 4311, the fourth flip part 432 includes a fourth flip bottom plate 4321, and the third flip bottom plate 4311 and the fourth flip bottom plate 4321 are connected in a V shape; the second rotating shaft part 433 includes a second sleeve 4331 and a second rotating shaft 4332, the second sleeve 4331 is fixedly connected between the third flip bottom plate 4311 and the fourth flip bottom 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 installation frame 41, and the second sleeve 4331 is sleeved on the outer periphery of the second rotating shaft 4332, and the second sleeve 4331 is rotatably connected to the second rotating shaft 4332. The rear wheel is locked in the rear wheel receiving groove 44 by the tangent points where the rear wheel abuts against the front baffle 421 , the third flip bottom plate 4311 and the fourth flip bottom plate 4321 and the deadweight of the rear wheel.

[0103] To further illustrate, the weight of the third flipping portion 431 is greater than the weight of the fourth flipping portion 432, that is, the flipping of the fourth flipping 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 flipping portion 432, the rear wheel flipping portion 43 flips backward under the action of gravity.

[0104] For further explanation, see Figure 12 to Figure 14 The third flip portion 431 also includes a third flip side plate 4312, and the left and right ends of the third flip bottom plate 4311 are respectively connected to the third flip side plate 4312, and the third flip bottom plate 4311 and the third flip side plate 4312 are enclosed to form a third through groove 4313; the fourth flip portion 432 also 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 plate 4322, and the fourth flip side plate 4322 is fixedly connected between the third flip side plate 4312 and the fourth flip bottom plate 4321 on the same side; the fourth through groove 4323 is enclosed between the fourth flip bottom plate 4321 and the fourth flip side plate 4322, and the third through groove 4313 and the fourth through groove 4323 are communicated with each other. 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 .

[0105] 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 suitable for fixing rear wheels of different sizes.

[0106] When parking, the rear wheel presses over the third flip part 431 and the fourth flip part 432 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 flip part 43 can be triggered to flip forward, so that the fourth flip bottom plate 4321 flips to be pressed by the rear wheel. At this time, the front end of the rear 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. The rear wheel is locked by the tangent points where the rear wheel abuts against the front baffle 421, the third flip part 431 and the fourth flip part 432, and the deadweight of the rear wheel. The rear wheel is locked between the rear wheel fixing part 42, the rear wheel flip part 43 and the sunken mounting frame 41, so that the rear wheel is firmly locked.

[0107] For further explanation, see Fig.14 The third flip part 431 further includes a hanging plate 4314, which is arranged one-to-one with the third flip side plate 4312; one end of the hanging plate 4314 is fixedly connected to the upper side of the third flip side plate 4312, and the other end of the hanging plate 4314 is extended outwardly above the left and right side walls of the sunken installation frame 41. By providing the hanging plate 4314, when the rear wheel flip part 43 flips forward, the hanging plate 4314 can abut against the upper end of the sunken installation frame 41 to play a supporting role, thereby preventing the rear wheel flip part 43 from flipping forward too much.

[0108] For further explanation, see Figure 12 to Figure 14The 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 installation 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 avoid the support block 45 when the third flip bottom plate 4311 is flipped forward and backward. Specifically, the avoidance through hole 43111 is used to enable the third flip bottom plate 4311 to avoid the support block 45 when flipping forward and backward. When the rear wheel flip part 43 flips forward, the third flip bottom plate 4311 flips forward until the support block 45 is completely disengaged from the avoidance through hole 43111; when the rear wheel flip part 43 flips backward, the third flip bottom plate 4311 flips backward and allows the support block 45 to pass through the avoidance through hole 43111.

[0109] By providing the support block 45, when the rear wheel needs to be unlocked, the rear wheel is moved backward so that the rear wheel can move backward against the support block 45, so that the support block 45 can support the rear wheel to move backward.

[0110] For further explanation, see Fig.14 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, the other end of the second support portion 452 extends to the lower side of the third flip bottom plate 4311, and the upper end surface of the second support portion 452 abuts against the lower end surface of the third flip bottom plate 4311. The second support portion 452 can support the rear wheel flip portion 43.

[0111] Further, the upper end surface 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 flipping portion 43 flips forward and presses the rear wheel flipping portion 43. By providing the first support portion 451 and the second guide slope 4511, the displacement of the rear wheel can be supported and guided. When picking up the car, by providing the second guide slope 4511, the rear wheel can move backward along the second guide slope 4511 to facilitate the pushing out of the rear wheel.

[0112] In other embodiments, see Figure 2The front inclined parking rack also includes a cart platform 6, which is fixedly connected to the front wheel slide 2, and the cart platform 6 is located behind the steering mechanism 3, and the rear wheel fixing mechanism 4 is located at the lower side of the cart platform 6; the cart platform 6 includes a platform body 61, and the upper end surface of the platform body 61 is provided with a cart slope 611, one end of the cart slope 611 is connected to the bottom surface of the rear end of the front wheel flip part 52, and the other end of the cart slope 611 is inclined downward in a direction away from the front wheel flip part 52. By setting the cart slope 611, when parking, it is convenient for the user to push the front wheel of the vehicle into the front wheel fixing mechanism 5 through the cart slope 611 to achieve the fixing of the front wheel; when picking up the vehicle, the front wheel can also be pushed away from the front wheel fixing mechanism 5 through the cart slope 611, so that the user can push the cart more smoothly and labor-saving when parking and picking up the vehicle.

[0113] For further explanation, see Figure 2 and Figure 6 , the cart platform 6 also includes a buffer pad 62, which is connected to the upper end surface of the platform body 61, and the buffer pad 62 is located on the side of the cart inclined surface 611 close to the front wheel flip part 52, and the bottom of the rear end of the front wheel flip part 52 is supported on the buffer pad 62. Specifically, the platform body 61 supports the front wheel flip part 52, and by providing the buffer pad 62, the impact force of the front wheel flip part 52 on the platform body 61 can be further buffered. The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
