Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorbing mechanisms, and in particular relates to an easy-to-maintain steering wheel shock absorbing mechanism. Background Art

[0002] AGV, short for "Automated Guided Vehicle," refers to a transport vehicle equipped with an automatic guidance system, such as electromagnetic or optical, that follows a prescribed path and features safety features and various transfer functions. AGVs can travel in all directions while operating autonomously, and both front and rear wheels can follow the guide line when turning, resulting in excellent maneuverability and suitability for working in narrow aisles.

[0003] The AGV steering wheel is a mechanical structure that integrates a drive motor, steering motor, and reducer. It is primarily used for driving and steering AGVs (Automated Guided Vehicles). Compared to traditional AGV differential speed control methods, it offers higher levels of integration, adaptability, and precision. Its integrated design simplifies AGV design and manufacturing processes and reduces maintenance costs.

[0004] Traditional steering wheel shock absorber springs rely on selection calculations and cannot be adjusted synchronously with the load, making replacement and maintenance inconvenient. Utility Model Content

[0005] The purpose of the utility model is to provide an easy-to-maintain steering wheel shock-absorbing mechanism, which mainly solves the problem that the existing AGV steering wheel shock-absorbing mechanism is inconvenient to replace and maintain.

[0008] Furthermore, in the present invention, the guide structure includes a guide column fixedly connected to the shock-absorbing mounting plate by screws, and a linear bearing matched with the upper end of the guide column and fixed to the lower end of the buffer plate.

[0009] Furthermore, in the present invention, a plurality of mechanical limit plates are provided on the shock-absorbing mounting plate, and a buffer gap is provided between the upper ends of the mechanical limit plates and the buffer plate.

[0010] Furthermore, in the present invention, four guide structures are evenly arranged on the circumference of the buffer plate, and the through hole is arranged between every two guide structures.

[0011] Furthermore, in the present invention, the spring adjustment plate is composed of a horizontal plate and ear plates on both sides thereof, and one end of the shock-absorbing spring passing through the through hole is located in the arched space of the horizontal plate; the ear plate is connected to the buffer plate through a spring adjustment bolt.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) The shock-absorbing mechanism of the utility model allows for stepless adjustment of the spring force, ensuring just the right amount of downward force.

DETAILED DESCRIPTION

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0018] Example

[0019] like Figure 1As shown, the utility model discloses an easy-to-maintain steering wheel shock-absorbing mechanism, which includes a steering wheel structure 1, a circular shock-absorbing mounting plate 2 provided on the steering wheel structure 1, a plurality of shock-absorbing spring mounting grooves 3 provided on the shock-absorbing mounting plate 2, a circular buffer plate 5 connected to the shock-absorbing mounting plate 2 through a plurality of guide structures 4, a through hole 6 provided on the buffer plate 5 and corresponding to the position of the shock-absorbing spring mounting groove 3, a shock-absorbing spring 7 with one end inserted into the shock-absorbing spring mounting groove 3 and the other end passing through the through hole 6, and a spring adjustment plate 9 covering the through hole 6 and connected to the buffer plate 5 through a spring adjustment bolt 8. When in use, the chassis of the AGV trolley is fixed on the spring adjustment plate 9. When the AGV trolley moves through the steering wheel, the shock-absorbing spring is used to achieve shock absorption of the trolley. The shock-absorbing mechanism facilitates the stepless adjustment of the spring elastic force using the spring adjustment bolt 8 to ensure just the right amount of downward force, and is convenient for replacement and maintenance. At the same time, the structure occupies little space, which is conducive to reducing the size of the AGV body.

[0020] In this embodiment, the guide structure 4 includes a guide post 13 fixedly connected to the shock-absorbing mounting plate 2 via screws, and a linear bearing 14 that cooperates with the upper end of the guide post 13 and is fixed to the lower end of the buffer plate 5. The guide structure 4 is primarily used to achieve the upper limit of the buffer plate 5. Correspondingly, a plurality of mechanical limit plates 10 are provided on the shock-absorbing mounting plate. A buffer gap is provided between the upper end of the mechanical limit plates 10 and the buffer plate 5, and the mechanical limit plates 10 are used to achieve the lower limit of the buffer plate. Specifically, four guide structures 4 are evenly arranged around the circumference of the buffer plate 5, and a through hole 6 is provided between every two guide structures 4.

[0021] In this embodiment, the spring adjustment plate 9 consists of a horizontal plate 11 and two side tabs 12. One end of the damping spring 7, which extends through the through-hole 6, is positioned within the arched space of the horizontal plate 11. The tabs 12 are connected to the buffer plate 5 via spring adjustment bolts 8. During installation, the lower end of the damping spring 7 is inserted into the damping spring mounting slot 3. The damping spring 7 is then pressed against the horizontal plate 11, resulting in a compressed state. To adjust the spring preload, simply adjust the spring adjustment bolts 8 at each end.

[0022] Through this design, the shock-absorbing mechanism of this utility model allows for infinitely adjustable spring force, ensuring just the right amount of downforce. This also facilitates replacement and maintenance. Furthermore, this structure occupies minimal space, contributing to a reduction in the size of the AGV itself. Therefore, compared to existing technologies, this utility model offers substantial advantages and advancements.

[0023] The above embodiment is only one of the preferred implementation methods of the present invention and should not be used to limit the scope of protection of the present invention. Any changes or modifications that have no substantive meaning made to the main design concept and spirit of the present invention, as long as the technical problems they solve are still consistent with the present invention, should be included in the scope of protection of the present invention.
