Description

Technical Field

[0001] The utility model relates to the technical field of spring guide rail buffering, in particular to a spring guide rail buffering suspension structure of a Mecanum wheel. Background Art

[0002] The Mecanum wheel is a patented product of the Swedish Mecanum company. It has a unique design with many small rollers distributed on the rim, which can achieve all-round movement. The special design of the small rollers allows the wheel to slide laterally, thereby achieving flexible all-round movement while keeping the wheel's own direction unchanged.

[0003] There are various products on the market at present, mainly single-wheel supplies. When provided to customers as a wheel, customers need to configure the reducer, suspension, motor, etc. by themselves. As an integrated product, there are very few, which brings great inconvenience to customers.

[0004] In addition, the existing suspension structure of Mecanum wheels usually uses obliquely arranged buffers for buffering, which requires a large lateral space. Therefore, there must be enough space in the vehicle body to accommodate the entire structure. Summary of the Invention

[0005] In order to make up for the above shortcomings, the utility model provides a spring guide rail buffer suspension structure of a Mecanum wheel, which aims to improve the traditional Mecanum wheel. Customers need to configure the reducer, suspension and motor by themselves when using it, which brings inconvenience to customers.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A spring guide rail buffer suspension structure for a Mecanum wheel includes a horizontal mounting platform, a suspension bracket fixedly provided on one side of the bottom of the horizontal mounting platform, and a support plate provided on the other side. The suspension bracket and the support plate are arranged in parallel and connected by two linear guide rails. A horizontal mounting seat is provided on one side of the support plate, and two buffers are provided between the horizontal mounting seat and the horizontal mounting platform. A drive motor is provided in the middle of the support plate, and the drive motor is connected to the Mecanum wheel through a reducer.

[0008] Furthermore, the linear guide rail includes a sliding block and a track, the sliding block is fixed on the suspension frame, and the track is fixed on the support plate and is perpendicular to the horizontal mounting platform.

[0009] Furthermore, an installation limit groove is provided on the support plate corresponding to the track, and an upper limit column and a lower limit column are provided on the support plate on one side of the installation limit groove, and the upper limit column and the lower limit column are used to limit the moving stroke of the sliding block.

[0010] Furthermore, a flange connection plate is provided at the end of the output shaft of the reducer, and the Mecanum wheel is locked and connected to the flange connection plate.

[0011] Furthermore, the two linear guide rails and the two buffers are respectively arranged on the support plates on both sides of the drive motor, and the support plates are located between the linear guide rails and the buffers.

[0012] Furthermore, an avoidance hole is provided on the suspension bracket corresponding to the drive motor.

[0013] Furthermore, a mounting positioning groove and a lock hole are provided on the top of the horizontal mounting platform.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the present invention, the Mecanum wheel body, motor and reducer are integrated together through the suspension frame. The entire Mecanum wheel structure becomes a module, which is provided to the user as a module. The user does not need to equip the reducer, motor and suspension frame separately, thereby achieving the effect of convenient direct use by the user.

[0016] 2. In the present invention, a linear guide rail is used to combine the support plate for fixing the drive motor and the suspension frame for fixing to the vehicle body, so that the two can only move relative to each other in the vertical direction. By using the buffers arranged in the same direction, an effective vertical buffering effect can be formed, and there is no need to consider the force in the horizontal direction. Based on this, the volume of this part of the suspension structure in the horizontal direction can be reduced, so that it can be installed in a limited space. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figures 1-4 The utility model provides an embodiment: a spring guide rail buffer suspension structure of a Mecanum wheel, comprising a horizontal mounting platform 1, a suspension bracket 2 fixedly provided on one side of the bottom of the horizontal mounting platform, and a support plate 3 provided on the other side, the suspension bracket and the support plate are arranged in parallel and connected by two linear guide rails 4, a horizontal mounting seat 5 is provided on one side of the support plate, two buffers 6 are provided between the horizontal mounting seat and the horizontal mounting platform, a drive motor 7 is provided in the middle of the support plate, and the drive motor is connected to the Mecanum wheel 8.

[0023] The horizontal mounting platform is used to be fixed to the frame, and its surface is provided with mounting positioning grooves 17 and lock holes 18. The mounting positioning grooves facilitate users to quickly locate the installation position, and the horizontal mounting platform can be fixed to the frame by screws; the suspension frame and the horizontal mounting platform are fixed as an integrated structure. In order to increase the connection strength, reinforcing ribs can be provided to assist in fixation; the suspension frame is connected to the support plate through two linear guides. In the horizontal direction, the two are limited by the linear guides and can only move relative to each other in the vertical direction. The buffer is then provided to provide a buffering effect in the vertical movement. Such a design eliminates the need for the buffer to be arranged obliquely, and can greatly reduce the distance between the suspension frame and the support plate, that is, the Mecanum wheel and the suspension frame are closer. Therefore, when the Mecanum wheel cannot protrude from the frame or cannot protrude too much, the space below the frame occupied by the suspension frame is reduced, which is convenient for the design of the bottom space of the frame.

[0024] Since the driving motor is arranged on the support plate and the suspension bracket is close to the support plate, an avoidance hole 161 is provided on the suspension bracket corresponding to the driving motor to ensure that there is sufficient installation space without affecting the lifting action.

[0025] To ensure stability during use, two linear guides and two buffers are respectively arranged on the support plates on both sides of the drive motor, and the support plates are located between the linear guides and the buffers. The displacement generated by the Mecanum wheel as the fulcrum can be buffered on both sides, and the force is stable and reliable.

[0026] Specifically, the linear guide rail includes a sliding block 9 and a track 10. The sliding block is fixed to the suspension bracket, and the track is fixed to the support plate and is perpendicular to the horizontal mounting platform. A mounting limit slot 11 is provided on the support plate corresponding to the track to facilitate track installation, ensure a vertical position after installation, avoid jamming during the lifting process, and improve assembly accuracy. Furthermore, an upper limit post 12 and a lower limit post 13 are provided on the support plate on either side of the mounting limit slot. These upper and lower limit posts are used to limit the travel of the sliding block, thereby ensuring that the sliding block does not deviate from the track in the event of buffer failure or excessive load.

[0027] The output shaft of the drive motor is connected to the reducer 15, which is also fixed to the support plate. Its rotation is smooth and reliable. The end of the output shaft 141 of the reducer is provided with a flange connection plate 14. The Mecanum wheel is locked and connected to the flange connection plate, which is convenient for quick assembly and replacement. A weight reduction groove 16 is also provided on the top of the support plate. This part does not affect the overall structural strength and can effectively reduce the overall weight. When the load is too large, the top of the support plate can also conflict with the horizontal mounting platform to limit the further downward movement of the horizontal mounting platform, achieving the effect of travel limit. Rubber pads can be installed on the support plate to ensure good buffering during contact and reduce the vibration and abnormal noise caused by hard contact.

[0028] This application uses linear guides to limit the two relatively movable structures in the horizontal direction and restrict the movement in the vertical direction, so that the buffer installation does not need to be tilted, effectively reducing the size of the structure in the axial direction of the Mecanum wheel. The structure is compact and occupies little space at the bottom of the frame, which is beneficial to the layout design of other components at the bottom of the frame.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
