DETAILED DESCRIPTION

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0020] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0022] like Figure 1As shown, a floating drive mechanism 10 of the present application includes: a driving module 11, a floating arm 12, a first arm shaft seat 16, an elastic connection component 17, and a second arm shaft seat 18. The floating arm 12 is used to float and drive the driving module 11, the first arm shaft seat 16 is used to rotatably support the floating arm 12, the elastic connection component 17 is used to elastically support the floating arm 12, and the second arm shaft seat 18 is used to fix one end of the elastic connection component 17. Specifically, the driving module 11 is fixed to one end of the floating arm 12, the floating arm 12 is rotatably connected to the first arm shaft seat 16, and the two ends of the elastic connection component 17 are rotatably connected to the other end of the floating arm 12 and the second arm shaft seat 18, respectively. In this way, when the driving module 11 moves to a protruding ground, the elastic connection component 17 applies a downward flexible force to the driving module 11, pulling the driving module 11 to fit the ground; when the driving module 11 moves to a recessed ground, the elastic connection component 17 applies an upward flexible force to the driving module 11, thereby pulling the driving module 11 to avoid a hard collision between the driving module 11 and the ground.

[0023] Furthermore, the elastic connection assembly 17 includes: a first connection arm 171, a spring support arm 172, and a second connection arm 173. The two ends of the spring support arm 172 are fixedly connected to the first connection arm 171 and the second connection arm 173 respectively, the first connection arm 171 rotates to the other end of the floating support arm 12, and the second connection arm 173 is rotatably connected to the second support arm shaft seat 18. An elastic member 174 is also connected between the first connection arm 171 and the second connection arm 173, and the spring support arm 172 is sleeved on the outer periphery of the elastic member 174, which can further improve the elastic support performance of the drive module 11, thereby increasing the strength of the flexible force of the elastic connection assembly 17 pushing the drive module 11, thereby improving the overall stability of the chassis operation, and having stronger ground adaptability.

[0024] That is to say, the above-mentioned floating drive mechanism 10 flexibly supports the floating structure of the drive module 11 through the elastic connection component 17, so that when the drive module 11 floats up and down when driving along the uneven road surface, a reverse flexible resistance is applied to the drive module 11, so that the drive module 11 always maintains flexible contact with the ground when driving up and down, which can avoid the situation where the chassis goes straight up or down and hits the ground hard, thereby playing a certain protective role for the chassis, and can also improve the chassis's handling stability for the goods carried above, thereby ensuring the safety of cargo transportation.

[0025] As a specific implementation, the driving module 11 includes: a mounting frame 111, a driving wheel 112, a driving motor 113 and a driver 114. The driving wheel 112 is rotatably mounted on the outside of the mounting frame 111, the driving motor 113 is fixed to the inside of the mounting frame 111, and its motor shaft is connected to the driving wheel 112. The driver 114 is inserted into the socket of the driving motor 113 through a plug-in provided therein, and is electrically installed on the driving motor 113. Such a structure is easy to install and has a high degree of integration.

[0026] As a specific implementation, the mounting frame 111 is formed with a threaded hole, and one end of the floating arm 12 is formed with a matching hole 123 for matching the threaded hole. The mounting frame 111 is fixedly mounted on one end of the floating arm 12 by a screw 14 passing through the matching hole 123 and threadedly penetrating the threaded hole. Such a rigid connection structure makes the pushing operation of the floating arm 12 on the driving module 11 more stable.

[0027] Furthermore, a stopper 15 is provided at one end of the floating arm 12 to limit the installation position of the mounting frame 111 and one end of the floating arm 12. The stopper 15 is also formed with a matching hole 123 for matching the threaded hole, and the stopper 15 is also formed with a slot 151 for inserting the mounting end 1111 of the mounting frame 111, and the slot wall of the slot 151 fits the mounting end 1111 of the mounting frame 111. In this way, the installation accuracy of the rigid connection structure between one end of the floating arm 12 and the driving module 11 can be further improved, thereby ensuring the effectiveness of the flexible force applied by the elastic connection component 17 to the driving module 11.

[0028] As a specific implementation, the floating arm 12 is formed with a horizontal arm 121 and a bending arm 122 connected to the horizontal arm 121, the bending arm 122 is bent upward and forms an obtuse angle with the horizontal arm 121, the mounting frame 111 is fixed to one end of the horizontal arm 121 away from the bending arm 122, and the first connecting arm 171 is rotatably connected to one end of the bending arm 122 away from the horizontal arm 121. Such a structural design can improve the flexibility adjustment strength of the elastic connection component 17 on the driving module 11.

[0029] Specifically, the angle formed between the bending arm 122 and the horizontal arm 121 is 120 degrees. The angle formed between the bending arm 122 and the spring arm 172 is 90 degrees. Such an angle setting can ensure that the flexible force exerted by the overall structure of the elastic connection component 17 on the driving module 11 has the maximum effect, and maximize the flexible adjustment force of the elastic connection component 17 on the driving module 11.

[0030] like Figure 2 As shown, when the driving module 11 is traveling on a horizontal road, the floating driving mechanism 10 passes through according to the preset assembly position, that is, the original structural state.

[0031] like Figure 3 As shown, when the driving module 11 travels on a raised road surface, the driving module 11 moves upward along the Z axis, the driving module 11 is rigidly fixed on the floating arm 12, and rotates around the axis 1 along the J1 direction, and the elastic connection component 17 is compressed along the N direction to apply a flexible force to the driving module 11 in the reverse direction so that the driving module 11 adapts to the raised ground.

[0032] like Figure 4 As shown, when the driving module 11 travels on a sunken road surface, the driving module 11 moves downward along the Z axis, the driving module 11 is rigidly fixed on the floating support arm 12, and rotates around the axis 1 along the J2 direction. The elastic connection component 17 extends along the M direction to apply a flexible force to the driving module 11 in the reverse direction so that the driving module 11 has a tendency to move upward, thereby adapting to the ground depression.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the above embodiments do not limit the utility model in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the utility model.
