DEVICE FOR LATERAL TRANSLATION PARKING OF VEHICLES

TECHNICAL FIELD The application relates to the technical field of parking assistance devices, and in particular to a device for lateral translation parking of vehicles.

BACKGROUND At present, the number of vehicles in the country is gradually increasing. As a result, the number of parking lots is growing slowly, and many drivers lack the technology to control their vehicles, which leads to the shortage of parking positions and unreasonable parking arrangement. Among them, the side parking needs a certain space. When the front-back distance of a side parking position is too short, it is not easy for the driver to park or drive out. Even if the driver is skilled, the time spent is longer than that of ordinary parking. Therefore, it is necessary to find a reasonable way to reduce the difficulty of parking so as to shorten the time of vehicle side parking, so that people don't have to waste more time on parking alignment.

The types of existing parking assist devices are few, and due to their designs, different vehicle types need to be changed into different sizes, so that the existing parking assist devices cannot be widely popularized, for example, a device which can be placed on both sides of a wheel in a plug-in way through two rods can be used only by allowing a vehicle to drive into the corresponding device. The device is mainly divided into two parts, one is a front wheel device and the other is a rear wheel device. The principle is to drive the front wheel device to rotate when the wheels rotate, and the front wheel device transmits torque to the wheels of the front wheel device through the mutual cooperation of a worm and a turbine, thereby realizing the transverse movement of the front wheel device. The rear wheel device is connected with the front wheel device through a universal coupling, and the rear wheel device is a directional wheel, so that the rear wheel device and the front wheel device can move transversely in the same direction and at the same rotating speed. However, as we all know, different vehicle types will have different wheelbases and wheel tracks, so the distance between the two front wheel devices, the distance between the two rear wheel devices and the distance between the front wheel device and the rear wheel device will need to be adjusted according to the wheelbases and wheel tracks 5025 47 of different vehicle types. Therefore, each time when using and after using, it has to be manually folded and unfolded, or correspondingly adjusted, which is troublesome to use.

In addition, there is also a hydraulic vehicle moving device which adopts the principle that the vehicle is lifted by four hydraulic devices to enable the vehicle to leave the ground, and then the device is provided with universal wheels so that the vehicle can move at will, the operation is simple, however, the disadvantage is that such movement will take a lot of effort when encountering a sloping ground, and basically, such a device, although convenient to carry, does not need to be installed on the ground, but needs to be manually moved, so it will be relatively laborious.

DESCRIPTION OF THE APPLICATION The present application is described in detail below with reference to the accompanying drawings and examples.

It should be noted that the terms of "upper" and "lower" in this paper are relative to the 5095 47 perspective of the drawings, and are only for convenience of description and should not be construed as limiting the technical scheme.

As shown in FIG. 1- FIG. 8, the application provides a device for lateral translation parking of vehicles, so as to realize the lateral translation of parked vehicles, facilitate the parking of vehicles and reasonably arrange parking spaces, reduce the occupied space for the parking of vehicles, and avoid the need of reserving the distance between the parked vehicles and the front and rear vehicles when the vehicles pass in and out. Compared with the existing lateral translation parking device, the device directly moves a vehicle to a parking space by taking the parking platform 1 as a whole, can automatically convert a driving mode for moving the parking platform 1 when the vehicle is available or not, and meets the requirement of driving power. When a vehicle is parked on the parking platform 1, the device is driven to translate by the first transmission mechanism 22, so that the device is more stable and reliable; when there is no vehicle on the parking platform 1, it can be driven by the second transmission mechanism 23, and the parking platform 1 can be moved out and stored quickly and labor-saving. Different driving modes are applied according to different situations, so as to avoid unnecessary damage caused by the frequent use of one of the driving structures in non-corresponding situations, and effectively prolong the service life of the driving mechanism.

The device of the application comprises a parking platform 1 and a driving mechanism 2 arranged below the parking platform 1, the driving mechanism 2 is used to laterally translate the parking platform 1, the driving mechanism 2 includes a motor 21, a first transmission mechanism 22 and a second transmission mechanism 23, both of which are linked with the parking platform 1; the parking platform 1 is provided with a movable plate 11, and the movable plate 11 is connected with the upper surface of the parking platform 1 through an elastic piece 12, which is generally set as a spring, the bottom of the parking platform 1 is provided with a conversion mechanism 3 linked with the movable plate 11. The conversion mechanism 3 is used to link the motor 21 with the first transmission mechanism 22 or the motor 21 with the second transmission mechanism 23. According to the application, the movable plate 11 moves up and down, that is, when there is a vehicle, the movable plate 11 is pressed down, and when there is no vehicle, the movable plate 11 is supported by the elastic piece 12, so that the feedback between the vehicle and the vehicle on the parking platform 1 can be realized, and then different transmission modes can be changed. In addition, sensors can also be used to realize this function, 502547 However, since the vehicle is easy to raise dust from the top and bottom, the feedback and linkage operation of the mechanical structure are more stable, and the signal failure of sensors can be avoided. The bottom of the parking platform 1 1s also provided with a guide mechanism 4, which is used to guide the parking platform 1 to reciprocate linearly along the driving mechanism 2. The guiding mechanism 4 further ensures that the parking platform 1 can stably translate under the action of the gravity of the vehicle, and it is not easy to break away from the specified track direction or make the vehicle slide by force.

In the embodiment, the motor 21 is connected with a driving shaft 211 which 1s provided with a driving gear 212, the first transmission mechanism 22 includes a screw 221, a first gear 222 meshed with the driving gear 212 is arranged on the screw 221, and a half nut 223 is fixedly arranged at the bottom of the parking platform 1, and the half nut 223 is matched with the screw

221. The motor 21 drives the driving shaft 211 as the power source, and the linkage between the first transmission mechanism 22 and the motor 21 is realized by the meshing of the first gear 222 and the driving gear 212, when the first transmission mechanism 22 is switched to work, the screw 221 is pushed up and engaged with the half nut 223. The motor 21 is driven by gears to realize the rotation of the screw 221 and drive the parking platform 1 to reciprocate linearly along the screw 221; this movement mode is more stable, and it is suitable for the situation that the vehicle has been parked on the parking platform 1. The angle à of the inner edge of the cross section of the half nut 223 is 160°, as the screw 221 needs to move up and down, the design of this angle facilitates the screw 221 to be fully engaged with the half nut 223 when it is pushed up from below, and also ensures that the screw angle on the screw 221 is sufficient and has sufficient force to drive the parking platform 1 to translate.

In the embodiment, the second transmission mechanism 23 comprises a driven shaft 231 provided with a second gear 232 meshed with the driving gear 212, the driven shaft 231 is interlocked with a first rotating shaft 234 through a bevel gear set 233, the first rotating shaft 234 is interlocked with a second rotating shaft 236 through a sprocket set 235, the second rotating shaft 236 is provided with a spur gear 237, a rack 238 is fixed at the bottom of the parking platform 1, and the rack 238 is meshed with the spur gear 237. The linkage between the second transmission mechanism 23 and the motor 21 is realized by the engagement of the second gear 232 with the driving gear 212. The motor 21 starts to drive the driving shaft 211 and thus is linked to the driven shaft 231. Then, the transmission direction is changed by the bevel gear Sh500547 233, so that the central axis of the first rotating shaft 234 is perpendicular to the central axis of the driven shaft 231, then, the rack 238 and the spur gear 237 are matched to drive the parking platform 1 to reciprocate linearly. Between the first rotating shaft 234 and the second rotating shaft 236, a sprocket set 235 is inserted to realize linkage, so that when the transmission mode is changed, the power of the motor 21 does not need to be changed to match different transmission modes, because both the screw-nut transmission mode and the rack-and-pinion transmission mode require the parking platform 1 to complete the same translational distance, but the rotational speeds and transmission ratios of the two modes cannot be the same, the addition of the sprocket set 235 can change the rotational speed of the shaft at a constant linear speed to accommodate the rack-and-pinion transmission mode. As the linkage of the gear and rack is shorter than the moving distance of the screw and nut, it can be faster and labor-saving, but it is not suitable for being pressed by gravity to complete the transmission, otherwise it will cause damage or self-locking, so the transmission mode is suitable for the situation that the extension of the parking platform 1 before the vehicle is ready to use the device and the load of the whole device is small when the parking platform 1 is retracted after the vehicle is ready to use the device.

In the embodiment, the conversion mechanism 3 includes a lever module 31 and a linkage module 32; one end of the lever module 31 is connected with the movable plate 11, and the other end of the lever module 31 is connected with the screw 221. The lever module 31 is used for engaging the screw 221 with the half nut 223 or separating the screw 221 from the half nut 223; one end of the linkage module 32 is connected with the screw 221, and the other end of the linkage module 32 is connected with the driven shaft 231, and the linkage module 32 is used for separating or meshing the bevel gear set 233. The conversion mechanism 3 is interlocked with the movable plate 11. When the movable plate 11 is pressed down, the lever module 31 is driven to mesh the screw 221 with the half nut 223, and the interlocking module 32 separates the bevel gear set 233, i.e. the first transmission mechanism 22 is interlocked to prevent the second transmission mechanism 23 from being interlocked; on the other hand, when the movable plate 11 is lifted without being affected by the gravity of the vehicle, the lever module 31 moves the screw 221 away from the half nut 223, and the linkage module 32 re-engages the bevel gear set 233, thereby using the linkage of the second transmission mechanism 23 to prevent the linkage of the first transmission mechanism 22. In addition, the linkage module 32 can be directly linked oc 47 with the vertical movement of the movable plate 11, or can be connected with the screw 221 to realize linkage.

In the embodiment, the lever module 31 comprises a shifting rod 311 and a connecting rod 312, one end of the shifting rod 311 is fixedly connected with the movable plate 11, and the other end of the shifting rod 311 is interlocked with the connecting rod 312; both ends of the connecting rod 312 are provided with a rotating rod 313, one end of the rotating rod 313 is hinged with the connecting rod 312, the other end of the rotating rod 313 is hinged with the screw 221, the middle part of the rotating rod 313 is hinged with a supporting piece 314, and the supporting piece 314 is in sliding connection with a bottom plate 315 fixed on the ground. The rotating rod 313, the supporting piece 314 and the bottom plate 315 in this structure are provided with a set at both ends of the screw 221, so as to make the radial movement of the screw 221 more stable. The movable plate 11 presses down to drive the shifting rod 311, so that the connecting rod 312 is pressed down synchronously, and then the screw 221 is lifted to cling to the half nut 223 by using the lever principle; the supporting piece 314 is not fixed and is in sliding connection with the bottom plate 315, in order to ensure that the screw 221 can keep moving vertically up and down under the limiting action, and to avoid the deviation of the rotation angle caused by the lever principle, so that the screw 221 cannot be aligned with the engagement of the half nut 223.

In the embodiment, the linkage module 32 comprises a fixing piece 321 for fixing the driving shaft 211 and a limiting piece 322 for limiting the driven shaft 231, the linkage module 32 further comprises a first coupling 323 and a second coupling 324, wherein the first coupling 323 is respectively sleeved with the screw 221, the driving shaft 211 and the driven shaft 231, and the second coupling 324 is respectively sleeved with the driving shaft 211 and the driven shaft 231. The linkage module 32 uses the first coupling 323 and the second coupling 324 to realize functions. In the same way as the lever principle, since the driving shaft 211 is fixed at a relative position by the fixing piece 321 and the bearing, when the screw 221 rises, the driven shaft 231 is pressed down to drive the bevel gear set 233 to separate; on the contrary, the screw 221 is lowered and the driven shaft 231 is reset, and the bevel gear set 233 is re-engaged, thereby realizing the use state transition of the second transmission mechanism 23.

The guide mechanism 4 can be matched with a grooved chute and a pulley such as a drawer,

however, when it is used in the parking of vehicles, it is easy to raise dust and cause stone 502547 particles and the like to fall into the groove-type chute, thus hindering the normal operation of the guide mechanism 4. Therefore, in this embodiment, the guide mechanism 4 comprises at least two slide rails 41, the cross section of the slide rails 41 is a convex cambered structure, and the slide rails 41 are fixedly arranged on the ground through the spacers 42; the bottom of the parking platform 1 is fixedly provided with pulley blocks 43 which are matched with the slide rails 41, and each pulley block 43 comprises two pulleys which are respectively arranged at two sides of the slide rails 41. The surface of the slide rail 41 is smooth, and debris such as stone particles and the like are not easy to remain; and the pulley block 43 is formed by two pulleys into a concave track which is matched with the slide rail 41, and the formed groove is downward, so that dirt and dirt are not easy to hide, and the pulley block 43 is convenient to disassemble and clean.

In the embodiment, two ends of the guide mechanism 4 are provided with limiting blocks 5, the bottom of the parking platform 1 is provided with a limiting part 13 which is matched with the limiting block 5, and one side of the limiting block 5 opposite to the limiting part 13 is provided with a switch 51 which is connected in series with the power supply of the motor 21. The limiting block 5 is fixedly arranged at an appropriate position on the ground for limiting the sliding of the parking platform 1 and preventing the parking platform 1 from being separated from the guide and limiting of the guide mechanism 4. In addition, a switch can be arranged on the limiting block 5 to control the start-up or turn-off of the motor 21, so as to realize automatic feedback and form a double insurance function, thus avoiding the damage caused by the motor continuing to run after the limiting block reaches the limit.

In the embodiment, the parking platform 1 has a hollow plate-like structure, which prevents vehicles from bringing dust and the like onto the platform and making it difficult to clean it. It is also convenient to observe whether the operation of the driving mechanism 2 is blocked, and the cost is saved. In addition, both ends of the parking platform 1 are provided with inclined plates 14 for vehicles to get up and down, so as to reduce the height difference between the parking platform 1 and the ground. The bottom of the parking platform 1 is also provided with a plurality of supporting wheels 15, which play a role in supporting and facilitating the movement of the parking platform 1. The supporting wheels 15 are universal wheels.

The principle of the application is as follows: First of all, the whole device is installed on the parking space where the vehicle should be parked, the parking platform is in a storage state, 502547 and the motor 21 is started, so that the first transmission mechanism 22 at this time is linked, that is, the driving shaft 211 is linked with the driven shaft 231 through the driving gear 212 and the second gear 232 in sequence, the bevel gear set 233 on the driven shaft 231 is not separated at this time, and can continue to interlock with the first rotating shaft 234 and the second rotating shaft 236, and the two rotating shafts are connected with the sprocket set 235 to adjust the transmission ratio and the rotating speed, so that the spur gear 237 on the second rotating shaft 236 drives the rack 238 on the bottom of the parking platform 1, and the parking platform 1 is moved outward.

In this process, the guide mechanism 4 maintains the linear motion of the parking platform 1, and the combination of the pulley block 43 and the slide rail 41 limits the parking platform 1 from being easily shaken or dislocated by the force.

When the limiting part 13 at the bottom of the parking platform 1 reaches the limiting block 5, the limiting part 13 will touch the switch 51 on the limiting block 5 to stop the continuous operation of the motor 21. At this time, the vehicle can advance to the parking platform 1 along the inclined plate 14. After stopping, the motor 21 is restarted to reverse.

As the vehicle's gravity presses the movable plate 11, the shifting rod 311 is pressed down, and the lever formed by the connecting rod 312, the rotating rod 313 and the screw 221 operates, the screw 221 rises and engages with the half nut 223, thus driving the parking platform 1 to begin to be housed and allowing the vehicle to enter a proper parking position.

However, due to the action of the first coupling 323 and the second coupling 324, the bevel gear set 233 on the driven shaft 231 is separated, the spur gear 237 and the rack 238 no longer provide power, and the parking platform 1 moves by the screw 221. When the vehicle needs to leave, by the same token, the side parking can be completed.
