Description

Technical Field

[0001] This utility model relates to the field of parking equipment technology, specifically to a vehicle carrier plate used in lifting and traversing parking equipment. Background Technology

[0002] Parking equipment is widely used in China, with lift-and-slide parking systems holding the largest market share. However, while lift-and-slide parking systems have relatively low manufacturing costs, they suffer from drawbacks such as lower safety and inconvenience in vehicle entry and exit, leading to a declining market share year by year. Manufacturers in the industry have continuously proposed various solutions to improve safety and ease of access, but the increased manufacturing costs associated with implementing these solutions have significantly reduced the cost-effectiveness of the equipment, preventing most solutions from being practically adopted. Therefore, a comprehensive solution that significantly improves the safety and ease of use of the equipment while maintaining or even slightly reducing manufacturing costs has become an urgent need within the industry. Summary of the Invention

[0003] Therefore, the technical problem to be solved by this utility model is to start with the vehicle platform, which accounts for more than 60% of the total cost, and adopt comprehensive technical means to achieve the goal of significantly improving the safety and ease of use of the equipment, while keeping the production cost basically the same or even slightly reducing it.

[0004] To solve the above problems, the present invention provides a vehicle carrier plate for a parking device, characterized in that the vehicle carrier plate is applied to a lifting and traversing parking device, including a lifting vehicle plate and a traversing vehicle plate.

[0005] The front is defined as the side closest to the lane and the rear as the side furthest from the lane, with the front-to-back direction being the longitudinal direction.

[0006] The lifting platform includes a platform body and a traction assembly;

[0007] The lateral moving platform includes a platform body and a lateral moving drive assembly.

[0008] The vehicle body includes a hollow rectangular frame, which is formed by fastening together a front transverse plate, a rear transverse plate, a first longitudinal plate, a second longitudinal plate, a first side beam, and a second side beam. The upper plane is the same horizontal plane, and the middle area is a cavity. The first side beam and the second side beam are located on the outer longitudinal direction of the rectangular frame and are the same length as the rectangular frame in the longitudinal direction. The front transverse plate and the rear transverse plate are located at the front and rear ends of the rectangular frame, respectively, and their transverse ends are close to the inner sides of the first side beam and the second side beam, respectively. The first longitudinal plate and the second longitudinal plate are located on the inner sides of the first side beam and the second side beam, respectively, and their front and rear ends are close to the front transverse plate and the rear transverse plate, respectively.

[0009] The vehicle body also includes a front stop lever, a first stop lever, a second stop lever, and a rear stop lever.

[0010] The front stop bar is fastened to the upper part of the middle position of the inner side of the front cross plate; the first stop bar and the second stop bar are respectively fastened to the upper part of the inner side of the first longitudinal plate and the second longitudinal plate, with the front end abutting against the front stop bar and the rear end extending to the outer side of the rear cross plate; the front stop bar, the first stop bar, and the second stop bar form a U-shaped member with the notch facing backward; the rear stop bar is fastened to the upper part of the outer side of the rear cross plate.

[0011] The traction assembly consists of four sets, each set including a load traction unit and a backup traction unit, which are respectively located at the front and rear ends of the vehicle body near the outer side.

[0012] The lateral drive assembly includes a lateral drive mechanism and rollers; the lateral drive mechanism is disposed on the vehicle body; the axis of the rollers is horizontally disposed above the vehicle body and parallel to the longitudinal centerline of the vehicle body, and includes a first roller, a second roller, a third roller, and a fourth roller, with the lower contour in rolling contact with the ground guide rail.

[0013] The first and second longitudinal plates of this technical solution serve as the driving passage for vehicles to enter the vehicle body. The front and rear transverse plates respectively support the wheels of the vehicle in a stationary state. The first and second side beams enhance the overall structural rigidity of the rectangular frame formed by the front and rear transverse plates, the first and second longitudinal plates, and can significantly improve the longitudinal bending strength of the vehicle body.

[0014] The main functions of the front lever, first lever, second lever, and rear lever are to prevent the wheels from overstepping their designated position when the vehicle enters the body of the vehicle body and when it is stationary. At the same time, they also help to enhance the overall rigidity of the body of the vehicle body.

[0015] The technical solution of this application sets the axis of the roller above the vehicle body, so that most of the roller's outline is located above the vehicle body, instead of the prior art which sets the roller entirely below the side beam or the vehicle body. Its advantage is that the height of the vehicle body can be made relatively small while meeting the rigidity requirements, which helps to reduce the overall height of the equipment, increase the applicability of the equipment, and facilitate the vehicle to drive into the vehicle platform.

[0016] Furthermore, according to the aforementioned vehicle platform of a parking device, the load traction unit includes a load traction chain, the load traction chain is vertically arranged, the upper end is mechanically connected to the terminal part of the lifting drive device of the parking device, and the lower end is fastened to the vehicle platform body.

[0017] The backup traction unit includes a backup traction chain and a chain status detection mechanism; the backup traction chain is vertically arranged, with its upper end mechanically connected to the terminal part of the lifting drive device of the parking equipment, and its lower end movably connected to the vehicle body; the chain status detection mechanism includes a position detection element connected to the circuit of the parking equipment control device, and the position detection element detects the position change status of the backup traction chain.

[0018] When the load traction chain breaks or becomes loose, the vehicle body moves downward and is pulled by the backup traction chain, the position detection element detects the aforementioned position change of the backup traction chain and sends a fault signal to the parking equipment control device, which then immediately instructs the equipment to stop operating.

[0019] Preferably, according to the aforementioned vehicle platform of a parking device, the chain status detection mechanism includes a mounting base, a compression spring, a movable screw, a nut, a detection washer, and a position detection element; the mounting base is fastened to the vehicle platform body, with a through hole perpendicular to the axis machined at the upper position and a cavity provided at the middle position, the compression spring being disposed in the internal area of ​​the cavity; the movable screw is vertically arranged, its upper end being mechanically connected to the lower end of the backup traction chain, and its lower end passing through the through hole of the mounting base and then through the compression spring; the nut is screwed in from the lower end of the movable screw and contacts the lower end face of the compression spring through the detection washer; the position detection element is disposed on the mounting base or the vehicle platform body to detect changes in the position of the compression spring.

[0020] The advantages of this technical solution are as follows: Under normal circumstances, the load traction chain is always under load, while the backup traction chain is adjusted by a nut and is in a tensioned but unloaded state under the action of a compression spring. At this time, the position detection element sends a normal status signal to the parking equipment control device. When the load traction chain breaks or becomes loose, the backup traction chain immediately becomes under load, and the compression spring is in its maximum compression state. This causes the position detection element to send a fault signal to the parking equipment control device, indicating that the load traction chain has broken or become loose. The parking equipment control device immediately takes measures including emergency shutdown of the equipment. This technical solution ensures that when the load traction chain breaks or becomes loose and the backup traction chain is connected, the lifting platform will only experience a slight relative displacement, which has minimal impact on the overall rigidity of the platform and will not cause a tipping accident.

[0021] Preferably, according to the aforementioned vehicle platform of a parking device, the lateral drive mechanism includes a motor reducer and a drive shaft; the motor reducer has a coaxial horizontal bidirectional output and is securely installed on one side of the rear of the vehicle platform body, with the output shaft parallel to the longitudinal centerline of the vehicle platform body; the output shaft at the rear end is securely installed with the first roller, and the output shaft at the front end is securely connected to one end of the drive shaft via a coupling; the other end of the drive shaft is securely installed with the second roller; the first roller and the second roller serve as driving rollers and are respectively disposed on one side of the vehicle platform body where the drive shaft is located; the third roller and the fourth roller serve as follower rollers and are respectively disposed on the other side of the vehicle platform body.

[0022] The hollow structure of the vehicle body in this technical solution allows the lateral drive mechanism to use a simplified mechanism that uses a motor reducer to drive two rollers in both directions. Compared with the existing technology that uses sprocket and chain transmission to drive the rollers, this simplifies the structure and reduces costs.

[0023] Preferably, according to the aforementioned parking equipment's vehicle platform, the lateral drive mechanism includes a rack, a drive gear, guide wheels, and a motor reducer; the rack is horizontally arranged and securely installed behind the ground parking space, parallel to the ground guide rail, with its teeth perpendicular to the ground; the motor reducer is securely installed behind the vehicle platform body, with its output shaft perpendicular to the ground, and the drive gear is securely installed thereon; the drive gear meshes with the rack; at least two guide wheels are provided, connected to the vehicle platform body via mounting seats, with their axes perpendicular to the ground, and are located on the side opposite to the teeth of the rack, making rolling contact with the side of the side opposite to the teeth of the rack; the first roller, the second roller, the third roller, and the fourth roller are all follower rollers, respectively located on both sides of the vehicle platform body.

[0024] This technical solution uses a motor reducer to drive the drive gear to rotate, thereby driving the transverse car plate to move, which has the advantages of strong driving capability and high displacement accuracy.

[0025] Preferably, according to the aforementioned vehicle platform of a parking device, the lateral drive mechanism includes a motor reducer, a drive sprocket, a driven sprocket, a chain, and a drive shaft; the motor reducer is fixedly installed at the middle position behind the vehicle platform body, and the output shaft is horizontally arranged and parallel to the longitudinal center line of the vehicle platform body; the drive sprocket is fixedly installed on the output shaft; the drive shaft is horizontally arranged, located on one side above the vehicle platform body, parallel to the longitudinal center line of the vehicle platform body, and the first roller and the second roller are respectively fixedly installed at both ends; the driven sprocket is fixedly installed on the drive shaft; the chain meshes with the drive sprocket and the driven sprocket respectively; the first roller and the second roller serve as drive rollers and are respectively arranged on one side of the vehicle platform body where the drive shaft is located; the third roller and the fourth roller serve as follower rollers and are respectively arranged on the other side of the vehicle platform body.

[0026] Furthermore, according to the aforementioned vehicle-carrying plate of a parking device, the front horizontal plate, the rear horizontal plate, the first longitudinal plate, and the second longitudinal plate are components formed by bending steel plates or components formed by rolling steel plates, and reinforcing plates or reinforcing ribs are provided at the fastener installation positions and at the positions bearing the main bending moment.

[0027] Furthermore, according to the vehicle platform of the parking equipment described above, the vehicle platform body of the lifting platform is characterized in that a drip-proof cover plate covering the cavity area is provided in the middle cavity position of the vehicle platform body.

[0028] The technical solution of this utility model has the following advantages:

[0029] This utility model provides a vehicle carrier plate for parking equipment, suitable for lifting and traversing parking equipment, compared with the closest prior art:

[0030] 1. The upper planes of the first side beam, second side beam, first longitudinal plate, second longitudinal plate, front cross plate, and rear cross plate of the vehicle body used for vehicle entry and parking are all on the same horizontal plane, which significantly improves the convenience of entering and exiting the vehicle. At the same time, the first side beam and second side beam enhance the overall structural rigidity of the hollow rectangular plate frame formed by the front cross plate, rear cross plate, first longitudinal plate, and second longitudinal plate, significantly improving the longitudinal bending strength of the vehicle body. The hollow rectangular plate frame structure saves materials and reduces manufacturing costs.

[0031] 2. The front stop, first stop, second stop, and rear stop installed on the vehicle body can prevent the wheels from overstepping the vehicle body when the vehicle enters the vehicle body and when it is stationary. At the same time, it can enhance the overall rigidity of the vehicle body.

[0032] 3. The axes of the four sets of rollers on the transverse platform are set above the platform body, so that most of the roller profile is above the platform body. The platform body can be made relatively small in height while meeting the rigidity requirements, which helps to reduce the overall height of the equipment, increase the applicability of the equipment, and facilitate the vehicle to drive into the platform.

[0033] 4. The lifting platform optimizes the structure of the existing single traction chain into a traction assembly that includes a load traction unit and a backup traction unit. This ensures that if the load traction chain breaks or loosens, or if the backup traction chain is connected to the main unit, the lifting platform will only experience a slight relative displacement, which has minimal impact on the overall rigidity of the platform and will not cause an overturning accident.

[0034] 5. By utilizing the optimized and improved structure of the vehicle body, several technical solutions for the transverse movement drive mechanism of the transverse movement vehicle body are provided that are simpler, lower in cost, and higher in precision compared with existing technologies.

Detailed Implementation

[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0056] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0057] like Figure 1 The diagram shown is a schematic diagram of the hollow rectangular frame 00 in the vehicle body of Embodiment 1 of this application. The diagram is a plan view, with the rear at the top and the front at the bottom.

[0058] As shown in the figure, the rectangular frame 00 is formed by fastening together the front horizontal plate 20, the rear horizontal plate 29, the first longitudinal plate 25, the second longitudinal plate 05, the first side beam 24, and the second side beam 06. The upper plane is the same horizontal plane, and the frame is symmetrically arranged with the longitudinal center line 01 of the vehicle body. The middle area is a cavity 11.

[0059] As shown in the figure, the first side beam 24 and the second side beam 06 are located on the longitudinal outer side of the rectangular frame 00 and are of the same length as the rectangular frame 00 in the longitudinal direction; the front horizontal plate 20 and the rear horizontal plate 29 are located at the front and rear ends of the rectangular frame 00, respectively, and their transverse ends are tightly attached to the inner sides of the first side beam 24 and the second side beam 06, respectively; the first longitudinal plate 25 and the second longitudinal plate 05 are located at the inner sides of the first side beam 24 and the second side beam 06, respectively, and their front and rear ends are tightly attached to the front horizontal plate 20 and the rear horizontal plate 29, respectively.

[0060] As is known from industry common sense, the first longitudinal plate 25 and the second longitudinal plate 05 serve as driving passages for vehicles to enter the vehicle body. When the vehicle body is stationary, the four wheels are located at the two end areas of the front transverse plate 20 and the rear transverse plate 29, respectively. Since the longitudinal dimension of the vehicle body is larger than its transverse dimension, the technical solution of this application provides a first side beam 24 and a second side beam 06 on both longitudinal sides of the vehicle body to further enhance the longitudinal bending strength of the vehicle body. It should be noted that the upper planes of the front transverse plate 20, the rear transverse plate 29, the first longitudinal plate 25, the second longitudinal plate 05, the first side beam 24, and the second side beam 06 of the technical solution of this application are on the same horizontal plane, which effectively improves the convenience of vehicles entering and exiting the vehicle body. Example 2

[0061] like Figure 2 The diagram shown is a schematic diagram of the vehicle body structure according to Embodiment 2 of this application. The diagram is a plan view, with the rear at the top and the front at the bottom.

[0062] As can be seen in the figure, the main body of the vehicle panel is formed by adding relevant baffle structures to the hollow rectangular frame 00 of Embodiment 1.

[0063] As shown in the figure: the front stop bar 09 is fastened to the upper part of the middle position of the inner side of the front cross plate 20; the first stop bar 23 and the second stop bar 10 are fastened to the upper part of the inner side of the first longitudinal plate 25 and the second longitudinal plate 05, respectively, with the front end abutting the front stop bar 09 and the rear end extending to the outer side of the rear cross plate 29; the front stop bar 09, the first stop bar 23, and the second stop bar 10 form a U-shaped component with the notch facing backward; the rear stop bar 03 is fastened to the upper part of the outer side of the rear cross plate 29.

[0064] The function of the front lever 09, the first lever 23, the second lever 10, and the rear lever 03 is to ensure that the wheels are properly positioned when the vehicle enters or exits the body panel; at the same time, the setting of the front lever 09, the first lever 23, the second lever 10, and the rear lever 03 can further improve the overall rigidity of the body panel. Example 3

[0065] like Figures 3 to 5 The diagram shown is a schematic representation of the lifting platform structure according to Embodiment 3 of this application; wherein, Figure 3 This is a floor plan; the top of the diagram represents the rear, and the bottom represents the front. Figure 4 yes Figure 3 A magnified view of a portion of area A; Figure 5 yes Figure 4 The sectional view of bb.

[0066] Investigation Figure 3It can be seen that the lifting platform is based on the platform body of Embodiment 2 with the addition of four sets of traction components 50. These four sets of traction components 50 are respectively set at the front and rear ends of the platform body near the outer side, and each set includes a load traction unit and a backup traction unit.

[0067] The following will focus on the examination Figure 5 (The left and right directions in the diagram are the vertical directions of the actual installation location.)

[0068] As shown in the figure: Mounting base 54 is securely mounted on the second longitudinal plate 05. The load traction unit in this embodiment is located at the bottom of the figure. The load traction chain is not shown (from industry common sense, this load traction chain should be securely connected to the upper end of the fixing screw 41 - that is, the right end in the figure). The fixing screw 41 in the figure is secured to the mounting base 54 by nuts 1 42 and nut 2 43. Nuts 1 42, nut 2 43 and fixing screw 41 are used to adjust the load traction chain to a suitable length position. The upper end of the load traction chain is vertically set and mechanically connected to the terminal part of the lifting drive device of the parking equipment. The lower end is securely connected to the vehicle body (in this embodiment, it is secured by fixing screw). The set of components, including rod 41, nut 1, nut 2, and mounting base 54, is fastened to the vehicle body and tows the vehicle. The backup traction unit of this embodiment is shown at the top of the figure. The backup traction unit includes a backup traction chain that is vertically arranged and a chain status detection mechanism. The upper end of the backup traction chain is mechanically connected to the terminal part of the lifting drive device of the parking equipment (the backup traction chain is not shown in the figure; it is known from industry common sense that the backup traction chain should be fastened to the upper end of the movable screw 55 - that is, the right end in the figure). The lower end is movably connected to the vehicle body (as shown in the figure, the lower end of the backup traction chain is movably connected to the vehicle body through the movable screw 55 and mounting base 54).

[0069] The figure shows the installation and matching relationship between the chain state detection mechanism and the movable screw 55 in this embodiment. The figure shows that the mounting base 54 is fastened to the second longitudinal plate 05 of the vehicle body. A through hole with a vertical axis is machined at the upper part, and a cavity is provided in the middle position. The compression spring 52 is located inside the cavity. The movable screw 55 is vertically arranged, with its upper end mechanically connected to the lower end of the backup traction chain, and its lower end passing through the through hole of the mounting base 54 and then through the compression spring 52. Nuts 3 56 and 4 57 are screwed in successively from the lower end of the movable screw 55, contacting the lower end face of the compression spring 52 through the detection washer 58 (washers 1 53 and 2 59 mainly enhance the stability and stress state of the compression spring 52). The position detection element 51, connected to the parking equipment control device wiring, is located on the outside of the mounting base 54, and its detection contact contacts the detection washer 58 to detect changes in the position of the compression spring 52.

[0070] In this embodiment, when the load traction chain breaks or loosens, the vehicle body moves downward and is pulled by the backup traction chain, the compression spring 52 is compressed to its shortest size, causing the detection pad 58 to shift to the right as shown in the figure. The position detection element 51 detects the rightward shift of the detection pad 58 (representing the load borne by the backup traction chain) and sends a fault signal to the parking equipment control device. The parking equipment control device immediately commands the equipment to stop operating. Example 4

[0071] like Figure 6 The diagram shown is a schematic diagram of the transverse moving platform structure of Embodiment 4 of this application; Figure 6 This is a floor plan; the top of the diagram represents the rear, and the bottom represents the front.

[0072] Investigation Figure 6 It can be seen that the lateral moving platform is based on the platform body of Embodiment 2 with the addition of a lateral moving drive component. The lateral moving drive component in this embodiment is a structure in which the motor reducer directly drives the rollers.

[0073] As shown in the figure: a ground guide rail 04 is set at the top and bottom of the figure. The lateral movement drive mechanism includes a motor reducer 27 and a drive shaft 22. The motor reducer 27 has a coaxial horizontal bidirectional output and is fixedly installed on one side of the rear of the vehicle body (left side in the figure). The output shaft is parallel to the longitudinal center line 01 of the vehicle body. The output shaft at the rear end is fixedly installed with a first roller 28, and the output shaft at the front end is fixedly connected to one end of the drive shaft 22 through a coupling 26. The other end of the drive shaft 22 is fixedly installed with a second roller 21. The first roller 28 and the second roller 21 serve as drive rollers. The first roller 28 and the second roller 21 are respectively set on one side of the position of the drive shaft 22 of the vehicle body (left side in the figure). The third roller 01 and the fourth roller 08 serve as follower rollers and are respectively set on the other side of the vehicle body (right side in the figure). Example 5

[0074] like Figure 7 The diagram shown is a schematic diagram of the transverse moving platform structure of Embodiment 5 of this application; Figure 7 This is a floor plan; the top of the diagram represents the rear, and the bottom represents the front.

[0075] Investigation Figure 7 It can be seen that the lateral moving platform is also based on the platform body of Embodiment 2, with the addition of a lateral moving drive component. The lateral moving drive component of this embodiment is a structure in which the motor reducer directly drives the lateral moving platform displacement through a gear and rack, and all rollers are follower rollers.

[0076] As shown in the figure: a ground guide rail 04 is set at the top and bottom of the diagram. The lateral movement drive mechanism includes a rack 36, a drive gear 35, a guide wheel 34, and a motor reducer (not shown in the figure). The rack 36 is horizontally set and fixedly installed behind the ground parking space, parallel to the ground guide rail 04, with its teeth perpendicular to the ground. The motor reducer is fixedly installed behind the vehicle body, with its output shaft perpendicular to the ground, and the drive gear 35 is fixedly installed thereon. The drive gear 35 meshes with the rack 36. At least two guide wheels 34 are provided, connected to the vehicle body through mounting seats, with their axes perpendicular to the ground. They are located on the other side of the teeth of the rack 36 and make rolling contact. The first roller 28, the second roller 21, the third roller 02, and the fourth roller 08 are all as follower rollers and are respectively set on both sides of the vehicle body.

[0077] This technical solution uses a motor reducer to drive the drive gear to rotate, thereby driving the displacement of the transverse carriage. It has the advantages of strong driving capability and high displacement accuracy. In practical applications, the motor reducer can also drive a sprocket and chain mechanism, using multiple gears and racks meshing and driving synchronously. Example 6

[0078] like Figure 8 The diagram shown is a schematic diagram of the transverse moving platform structure of Embodiment Six of this application; Figure 8 This is a floor plan; the top of the diagram represents the rear, and the bottom represents the front.

[0079] Investigation Figure 8 It can be seen that this transverse vehicle platform is also based on the vehicle platform body of Embodiment 2, with the addition of a transverse drive component. The transverse drive component in this embodiment is a structure in which a motor reducer drives a roller through a sprocket and chain mechanism.

[0080] As shown in the diagram: A ground guide rail 04 is installed at the top and bottom of the diagram. The lateral movement drive mechanism includes a motor reducer 27, a drive sprocket 31, a driven sprocket 33, a chain 32, and a drive shaft 22.
