[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the technical solution of the present invention is clearly and completely described below in combination with specific embodiments and with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] This embodiment introduces the structure of the carrier based on the vehicle body direction. Unless otherwise specified, the side surface refers to the side direction of the vehicle body, and the end surface refers to the front and rear direction of the vehicle body. Figure 1 As shown, this embodiment provides a transversely movable car transporter, including a base frame (not shown in the figure) and an upper frame (not shown in the figure), the base frame includes a middle bridge 1 and traveling bridge frames 2 arranged on both sides of the middle bridge 1, the traveling bridge frames 2 can drive the base frame to enter the bottom of the car body from between the front and rear wheels of the car in the transverse direction, the two traveling bridge frames 2 are respectively located on both sides of the bottom of the car body, the upper frame includes an upper frame 3 that can be lifted and lowered relative to the middle bridge 1 and two supporting mechanisms 4 fixed at both ends of the upper frame 3 and can extend in the forward and backward directions, the supporting mechanisms 4 can support the bottom of the wheels.

[0027] In this embodiment, the traveling bridge 2 moves laterally to the bottom of the vehicle, the supporting mechanism 4 cooperates with the wheels to support the vehicle, the vehicle is lifted by lifting the upper frame 3, and then the vehicle is moved laterally by the traveling bridge 2 to transport the vehicle to a designated position, thereby realizing the lateral transportation of the vehicle. The embodiment is suitable for parking lots with lateral parking spaces.

[0028] Combination Figure 2 The middle bridge 1 includes two fixed columns 11, and the walking bridge frame 2 includes a walking chassis 21. The two ends of the fixed columns 11 are respectively fixed to the bottom ends of the two walking chassis 21, and the fixed columns 11 and the walking chassis 21 are assembled into a rectangular frame.

[0029] Combination Figure 3 A walking wheel 22 with an axial direction parallel to the length direction of the walking chassis 21 is respectively arranged on both sides of the walking chassis 21, and the wheel axle of the walking wheel 22 is fixed on the end faces at both ends of the walking chassis 21, and a walking gear 221 is arranged on the wheel axle. A motion motor 23 is fixed on the walking chassis 21, and the motion motor 23 is connected to a driving rod 24 through a walking chain 231. Driving gears 241 meshing with the walking gear 221 are respectively fixed at both ends of the driving rod 24, so that the walking wheels 22 on both sides are driven to rotate synchronously by the motion motor 23; the motion motor 23 is arranged in the horizontal direction to reduce the height of the entire carrier, so as to facilitate entry and exit from the bottom of the vehicle body.

[0030] The two ends of the walking chassis 21 are respectively extended outward along the length direction and fixed with protective covers 25, and the protective covers 25 include side guard plates 251 respectively fixedly connected to the two sides of the end surface of the walking chassis 21 and end face guard plates 252 connecting the two side guard plates 251. The walking wheel 22 is in the protective cover 25, and the end face guard plate 252 is fixed with an anti-collision wheel 26, and the axial direction of the anti-collision wheel 26 is fixed in the vertical direction. Since the carrier provided in this embodiment enters the bottom of the vehicle body from the side, in order to prevent the vehicle body from being scratched, a settling channel for the chassis to pass through needs to be set, and the anti-collision wheel 26 can be set to guide and protect the operation of the walking wheel 22.

[0031] refer to Figure 4 The upper frame 3 includes lifting plates 31 on both sides and two connecting plates 32 connecting the two lifting plates 31. The ends of the connecting plates 32 are fixed to the bottom of the lifting plates 31. The connecting plates 32 and the lifting plates 31 are assembled into a rectangular structure. The two ends of the lifting plates 31 protrude outward relative to the connecting plates 32. Figure 3 Two bearing seats 27 are arranged on the walking chassis 21 along the length direction, and a screw rod 271 is fixed on the bearing seat 27. The screw rod 271 is arranged in the vertical direction. Two overhanging plates 311 are arranged on the lifting plate 31. The overhanging plates 311 are respectively screwed with a screw rod 271. The four screw rods 271 rotate synchronously so that the two lifting plates 31 can be lifted and lowered synchronously.

[0032] Recombination Figure 2 A driving platform 12 is fixedly arranged between the fixed columns 11, and a lifting motor 13 is fixed on the driving platform 12. The output shaft of the lifting motor 13 is arranged in the horizontal direction to reduce the height. The output end of the lifting motor 13 is connected to a sprocket (not shown) located below the driving platform 12 through a worm gear structure. A sprocket 272 is coaxially fixed to the lower end of the screw rod 271. A lifting chain 14 is wound around the five sprockets 272. The lifting chain 14 is driven to rotate by the lifting motor 13, so that the five sprockets 272 rotate synchronously, and finally the synchronous rotation of the four screw rods 271 is realized, and the two lifting plates 31 are lifted and lowered synchronously. In this embodiment, the lifting movement is driven by thread cooperation, and the thread has a self-locking function, thereby preventing the lifting plate 31 from falling. Further, the power of the lifting motor 13 is transmitted to the sprocket 272 through the worm gear structure, which can not only realize the conversion of the power direction, but also maintain the stability of the lifting plate 31 with the help of the self-locking function of the worm gear structure.

[0033] Refer to Figure 3 A guide rail 28 is fixed on the side guard plate 251 close to the middle bridge 1; Figure 5 The front and rear end surfaces of the guide rail 28 are respectively provided with a guide roller 281 fixed in the vertical direction; Figure 4A guide wheel 282 is fixed on one side of the lifting plate 31 facing the side guard plate 251, which is respectively in rolling cooperation with two guide rollers 281. The axial direction of the guide wheel 282 is perpendicular to the length direction of the lifting plate 31. The wheel surface of the guide wheel 282 is concave and cooperates with the guide roller 282, so that the guide rollers 282 at both ends clamp the guide rollers 281 at both ends of the guide roller 28 to guide the vertical movement of the lifting plate 31.

[0034] Refer to Figure 4 The support mechanism 4 includes a slide rod 41 that slides with the lifting plates 31 on both sides. The side of the lifting plate 31 has a sliding track 33. A slide key 411 is fixed on the slide rod 41 protruding toward one side of the lifting plate 31. The slide key 411 slides in the sliding track 33. The sliding tracks 33 used by the support mechanisms 4 at both ends are parallel and staggered to each other, so that the two support mechanisms 4 overlap and shrink on the lifting plate 31, thereby reducing the length of the lifting plate 31.

[0035] A limiting portion 42 is fixed to the end of the two sliding rods 41 facing the wheel, respectively. The limiting portion 42 and the sliding rod 42 are vertically fixed to the inner side of the two sliding rods 41. The end face of the limiting portion 42 is parallel to the connecting plate 32. The two limiting portions 42 are connected by a connecting portion 43. A telescopic platform 34 is fixed between the two connecting plates 32. Two screw nut assemblies 35 are fixed on the telescopic platform 34. The driving screw 351 of the screw nut assembly 35 is respectively connected to the connecting portion 43 of the front and rear support mechanisms 4. A telescopic motor 36 is fixed to the telescopic platform 34 in the horizontal direction. The output shaft of the telescopic motor 36 is connected to a pulley (not shown) below the telescopic platform 34 through a worm gear transmission. The screw nut assembly 35 is also provided with a pulley below the telescopic platform 34. The three pulleys are connected by a transmission belt (not shown). The telescopic motor 36 rotates to drive the driving screw 351 of the screw nut assembly 35 to extend and retract along the longitudinal direction of the vehicle body. The limiting portion 42 can extend toward the end face of the wheel to abut against the wheel, thereby abutting against the four tires through the four limiting portions 42 of the front and rear support mechanisms 4. After the upper frame 3 is lifted, the vehicle as a whole is lifted.

[0036] Furthermore, the connecting portion 43 includes an accommodating cavity 431 extending perpendicularly to the direction of the wheel from the limiting portions 42 on both sides, and the ends of the two accommodating cavities 431 are connected in a horizontal direction to form a power cavity 432. The accommodating cavity 431 accommodates a clamping arm 44 perpendicular to the end face of the limiting portion 42, and the clamping arm 44 can extend parallel to the end face of the limiting portion 42. The limiting portion 42 and the clamping arm 44 are in contact with the front and rear wheel surfaces of the wheel respectively; thereby, the front and rear wheel surfaces of the wheel are supported respectively to prevent accidental slipping.

[0037] The connecting portion 43 contains a driving arm 45, which includes two follower rods 451 parallel to the longitudinal direction of the vehicle body. The ends of the follower rods 451 away from the upper frame 3 are connected through a power rod 452. A rotating rod 461 perpendicular to the connecting plate 32 is connected to the side of the power rod 452 close to the upper frame 3. The follower rod 451 is accommodated in the accommodating cavity 431, and the power rod 452 is accommodated in the power cavity 432. The rotating rod 461 can rotate freely relative to the power rod 452. The surface of the rotating rod 461 has an external thread; a clamping motor 46 is fixed to one end of the power chamber 432 close to the upper frame 3, and a clamping gear (not shown) is fixed to the power end of the clamping motor 46, and the clamping gear is transmission-connected to a rotating gear (not shown), and a nut (not shown) threadedly engaged with the rotating rod 461 is fixed on the rotating gear, so that the rotating rod 461 is driven to telescope by the rotation of the clamping motor 46, thereby realizing the telescoping of the power rod 452 relative to the power chamber 432.

[0038] The outer side surface of the follower rod 451 is hingedly connected to a connecting rod 453, and the end of the clamping arm 44 is provided with a slider 441 which is perpendicular to the axial direction of the clamping arm 44, and the accommodating cavity 431 is provided with a slide groove 432 along the longitudinal direction of the vehicle body, and the slider 441 is provided with a clamping arm shaft 442 which can slide and rotate along the slide groove 432, and one end of the slider 441 connected to the clamping arm 44 is hingedly cooperated with the connecting rod 453, and there is a gap between the end of the slide groove 432 facing the power rod 452 and the front end of the accommodating cavity 431.

[0039] refer to Figure 6 In the initial state, the clamping arm 44 and the follower rod 451 are retracted in the accommodating chamber 431 along the longitudinal direction of the vehicle body, and the connecting rod 453 is parallel to the follower rod 451 and the clamping arm 44. When the transmission rod 461 moves linearly under the drive of the clamping motor 46, the follower rod 451 follows the power rod 452 to extend longitudinally along the vehicle body. Under the push of the connecting rod 453, the clamping arm 44 is also extended longitudinally along the vehicle body, and the clamping arm shaft 442 slides linearly in the slide groove 432. When the clamping arm shaft 442 abuts against the end of the slide groove 432 close to the power rod 452, the slider 441 can no longer extend forward, and the follower rod 451 continues to move linearly. Under the action of the connecting rod 453, the clamping arm 44 rotates relative to the clamping arm shaft 442 to be parallel to the end face of the limit portion 42, combined with Figure 7 Finally, the clamping arm 44 is locked in the lateral position of the vehicle body, and cooperates with the limiting part 42 and the front and rear wheel surfaces to support the wheel. The clamping motor 46 drives the transmission rod 461 to move through the screw nut structure, which can self-lock to prevent the clamping arm 44 from rotating and falling off.

[0040] The opposing surfaces of the limiting portion 42 and the clamping arm 44 are respectively arranged as inclined surfaces adaptively matched with the wheel surface, so that when the limiting portion 43 is extended, it can better contact and cooperate with the wheel, and when the wheels on both sides are not parked in alignment, the wheels can be pushed straight to prevent the wheels from falling off from between the limiting portion 42 and the clamping arm 44 due to deflection.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
