Description

Technical Field

[0001] The utility model relates to a vehicle, in particular to a guide rail type ground mobile platform. Background Art

[0002] At present, the guide rail type ground mobile platform on the market is connected to the guide rail by a clip-shaped guide rail block. Under the drive of the power mechanism, the guide rail type ground mobile platform moves along the guide rail. The disadvantage of this structure is that the friction between the guide rail block and the guide rail is relatively large, resulting in low efficiency of the power mechanism. In addition, more than two guide rails are usually used, which further reduces the efficiency of the power mechanism and increases energy consumption. If the guide rail type ground mobile platform is deformed, the friction will be further increased, and the movement will tend to slow down.

[0003] In addition, the guide rail type ground mobile platform usually uses a contact sensor to detect the moving distance. If there is no contact, then the moving distance cannot be detected, which is very inconvenient. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, one object of the present invention is to provide a ground mobile platform with high working efficiency and convenient detection of moving distance.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

The direction of the rack is the same as the direction of the guide rail structure. A gear is installed on the output shaft of the power motor, and the gear teeth of the gear are engaged with the tooth grooves of the rack.

[0009] The limiting structure includes an upper limiting plate installed on the side of the base frame and a lower limiting plate installed on the side of the mobile platform. The bottom of the upper limiting plate is provided with an outward upper bending portion to form an outward-opening strip groove, and the top of the lower limiting plate is provided with an inward upper bending plate. After assembly, the upper bending portion and the upper bending plate partially overlap, and the upper bending plate extends into the strip groove.

[0015] The beneficial effects of the present invention are as follows: compared with the existing technology, this product adopts a roller guide rail structure, which can greatly reduce the friction between the chassis and the mobile platform, improve the working power of the drive mechanism, and reduce energy consumption.

[0021] Reference Figures 1 to 3 A guide rail type ground mobile platform includes a base frame 1 and a mobile platform 2. The base frame 1 and the mobile platform 2 are connected by a roller type guide rail structure. There are at least two roller type guide rail structures. A driving mechanism for pushing the mobile platform to move is also provided between the base frame 1 and the mobile platform 2. The side surfaces of the base frame 1 and the mobile platform 2 are provided with limiting structures located outside the guide rail structure.

[0022] The roller-type guide rail structure is mainly used to reduce the friction force on the mobile platform 2 when it moves, and the limit structure is used to prevent the mobile platform from escaping from the guide rail structure during the movement of the mobile platform.

[0023] Compared with the existing technology, this product adopts a roller guide rail structure, which can greatly reduce the friction between the chassis and the mobile platform, improve the working power of the drive mechanism, and reduce energy consumption.

[0024] The driving mechanism includes a power motor 11 installed on the base frame and a rack 12 fixedly installed on the bottom of the mobile platform. The direction of the rack is the same as the direction of the guide rail structure. A gear is installed on the output shaft of the power motor. The gear teeth and the rack grooves are engaged. When the output shaft of the power motor rotates, the rack 12 is driven to drive the mobile platform 2, and the roller guide rail structure and the limit structure are used to improve stability. Even if the mobile platform is slightly deformed, even if the roller guide rail structure slips, it will not affect the driving mechanism to push the mobile platform.

[0025] The guide rail structure includes a V-shaped roller 21 installed on the bottom surface of the mobile platform and a triangular guide rail 22 installed on the base frame. The V-shaped roller slides on the triangular guide rail. This structure can greatly reduce friction and prevent the V-shaped roller and the triangular guide rail from detaching. It is also convenient to install.

[0026] The limiting structure includes an upper limiting plate 31 installed on the side of the base frame and a lower limiting plate 32 installed on the side of the mobile platform. The bottom of the upper limiting plate 31 is provided with an outward upper bending portion 311 to form an outward-opening strip groove 312, and the top of the lower limiting plate 32 is provided with an inward upper bending plate 321. After assembly, the upper bending portion 311 and the upper bending plate 321 partially overlap, and the upper bending plate 321 extends into the strip groove 312. This structure can prevent

[0027] A magnetic switch is also provided between the base frame 1 and the mobile platform 2 for sensing position changes of the mobile platform.

[0028] The magnetic switch between the chassis and the mobile platform is used to detect the moving distance of the mobile platform on the chassis. Compared with the contact sensor, it is easier to detect the moving distance and is convenient and practical.

[0029] Specifically, the magnetic switch includes a trigger component 41 installed on the top of the chassis and a magnetic sensing component 42 installed on the bottom of the mobile platform. The trigger component can be a permanent magnet or metal. The trigger component 41 is close to the magnetic sensing component 42 to make it send a signal. The signal of the magnetic sensing component 42 is sent to the processor in the form of voltage, current or pulse signal. The processor converts the signal of the magnetic sensing component 42 into a corresponding position, and then calculates the moving distance of the mobile platform according to the change in position. The trigger component 41 can be composed of one or more. Assuming that the mobile platform starts from a starting point (set according to needs and actual conditions), the trigger component 41 is set at a position a certain distance from the starting point. The magnetic sensing component 42 receives a signal once, indicating that the mobile platform has moved a certain distance, and determines the distance between the current position of the mobile platform and the starting point. The trigger component 41 is set on a support rod in the same direction as the triangular guide rail. The magnetic sensing component can be a magnetic induction transistor.

[0030] Specifically, an anti-skid plate 51 is installed on the top of the mobile platform 2.

[0031] Specifically, the anti-skid plate 51 is a checkered plate, which increases the friction with the cargo and prevents the cargo from being lost during transportation.

[0032] A grid-like reinforcement grille is provided at the bottom of the anti-skid plate 51 .

[0033] The above embodiments cannot limit the protection scope of the present invention. Equal modifications and changes made by those skilled in the art without departing from the overall concept of the present invention are still within the scope of the present invention.
