Description

Technical Field

[0001] The present application relates to the technical field of floor scrubbers, and in particular to a mobile mechanism. Background Art

[0002] The existing floor scrubbers are inconvenient to move around. The main brush cannot be raised, and because the chassis structure is too low to the ground, it is more laborious to push the brush. Even if the main brush is removed, it is still difficult to pass through obstacles such as speed bumps and low threshold steps due to the low chassis of the machine, which in turn causes the machine to be blocked from walking by low obstacles or potholes. In addition, the repeated disassembly and assembly of the main brush requires a large amount of work and is not easy to operate. Summary of the invention

[0006] By adopting the above technical solution, under the action of the power component, the floor scrubber can be switched from the transfer mode to the working mode, or from the working mode to the transfer mode, to realize the lifting function of the universal wheel, so that the structure on the chassis can be kept away from the ground to effectively avoid low obstacles or potholes. Compared with the prior art, the mobile mechanism of the present application is simple, easy and fast, and the whole structure is compact and smart, and only takes up a small space on the small floor scrubber to realize the relevant functions, which meets the application requirements.

[0007] Preferably, the power assembly includes a foot pedal, a foot pedal shaft, a lifting connecting rod and a connecting piece, the foot pedal is rotatably mounted on one end of the chassis away from the support shaft through the foot pedal shaft, one end of the lifting connecting rod is rotatably connected to the foot pedal, and the other end is rotatably connected to the connecting piece, and the connecting piece is assembled with the lifting transmission shaft.

[0008] By adopting the above technical solution, the state of the foot pedal is adjusted, and the lifting connecting rod and the connecting piece are used to transmit force. Under the cooperation of the parallelogram structure formed by the support shaft, the upper supporting connecting rod, the lower supporting connecting rod, and the chassis, the floor scrubber can be switched from the transition mode to the working mode, or from the working mode to the transition mode, thereby realizing the lifting function of the universal wheel.

[0013] Preferably, a tension spring is provided between the upper supporting link and the chassis.

[0014] By adopting the above technical solution, the setting of the tension spring can provide a function of fixing and maintaining the raised position of the parallelogram structure when it is raised, and provide a buffering and shock-absorbing effect to a certain extent, making the lifting process of the parallelogram structure more stable and reliable.

[0015] Preferably, running wheels are provided at the bottom of one end of the chassis, and the running wheels are distributed below the foot pedals.

DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-2 This application is described in further detail.

[0028] The embodiment of the present application discloses a moving mechanism.

[0029] Reference Figure 1 and Figure 2A mobile mechanism includes a support shaft 31, an upper support link 32, a lower support link 33, and a chassis 2. A link rotating shaft 5 is respectively arranged between one end of the upper support link 32 and the support shaft 31, and between one end of the lower support link 33 and the support shaft 31. A lifting transmission shaft 6 is respectively arranged between the other end of the upper support link 32 and the chassis 2, and between the other end of the lower support link 33 and the chassis 2. The support shaft 31, the upper support link 32, the lower support link 33, and the chassis 2 form a parallelogram structure. A power assembly 4 is arranged on the chassis 2, and the output end of the power assembly 4 is assembled with the upper support link 32.

[0030] Under the action of the power component 4, the parallelogram structure can be driven to swing up and down, so that the floor scrubber can switch from the transfer mode to the working mode, or from the working mode to the transfer mode, to realize the lifting function of the universal wheel 1, and then the structure on the chassis 2 can be kept away from the ground to effectively avoid low obstacles or potholes.

[0031] Reference Figure 1 and Figure 2 The power assembly 4 includes a foot pedal 41, a foot pedal shaft 42, a lifting connecting rod 43 and a connecting piece 44. The foot pedal 41 is rotatably mounted on one end of the chassis 2 away from the support shaft 31 through the foot pedal shaft 42. One end of the lifting connecting rod 43 is rotatably connected to the foot pedal 41, and the other end is rotatably connected to the connecting piece 44. The connecting piece 44 is assembled with the lifting transmission shaft 6.

[0032] The connecting member 44 includes a joint bearing 441 and a lifting shaft plate 442. The joint bearing 441 is rotatably mounted on one end of the lifting shaft plate 442. The end of the lifting connecting rod 43 close to the upper supporting connecting rod 32 is assembled with the joint bearing 441, and the other end of the lifting shaft plate 442 is assembled with the lifting transmission shaft 6.

[0033] Specifically, a through hole is provided at the end of the joint bearing 441, and an internal thread is provided at one end of the lifting link 43 close to the upper support link 32. The lifting link 43 is inserted into the through hole of the joint bearing 441 and reinforced with screws, so that the two are firmly connected together, the disassembly is stronger, and it is convenient for the operator to use.

[0034] More specifically, the lifting transmission shaft 6 is provided with a flat position, and the upper supporting connecting rod 32 is provided with a flat hole. The flat position and the flat hole are locked, thereby realizing the connection between the lifting transmission shaft 6 and the upper supporting connecting rod 32, and the rotation direction and rotation range of the entire parallelogram structure can be limited.

[0035] Reference Figure 1 A tension spring 7 is arranged between the upper supporting link 32 and the chassis 2, which can provide a fixation and maintain the raised position of the parallelogram structure when it is raised, and at the same time provide a buffering and shock absorbing effect, making the lifting process of the parallelogram structure more stable and reliable.

[0036] In the present application, a running wheel 8 and a universal wheel 1 are provided at the bottom of one end of the chassis 2, the running wheel 8 is distributed below the foot pedal 41, and the universal wheel 1 is distributed below the support shaft 31. The support shaft 31, the upper support link 32, the lower support link 33 and the chassis 2 are respectively connected to form a parallelogram structure that can swing up and down through the link shaft 5 and the lifting transmission shaft 6. The upper support link 32 and the lifting shaft plate 442 are connected and fixed on the chassis 2 through the lifting transmission shaft 6 to rotate, and can transmit the torque and supporting force of the foot pedal 41 through the joint bearing 441 and the lifting link 43.

[0037] In the application process, refer to Figure 1 When the floor scrubber is in the transfer mode, the foot pedal 41 is kicked in the forward direction with the foot, so that the foot pedal 41 can rotate forward and leave the limit dead point of contact with the chassis 2. At this time, the tension of the tension spring 7 causes the parallelogram structure to automatically rise to the fixed position where the universal wheel 1 contacts the chassis 2, and then it switches to the working mode.

[0038] When the scrubber is in working mode, refer to Figure 2 By stepping on the pedal with your foot, the foot pedal 41 can be rotated backward, and the torque is transmitted through the joint bearing 441 and the lifting link 43, so that the upper support link 32 rotates, thereby driving the parallelogram structure to press downward. When the foot pedal 41 rotates to the limit dead point in contact with the chassis 2, it switches to the transition mode.

[0039] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
