Description

Technical Field

[0001] The utility model relates to the technical field of service robot equipment, in particular to a service robot chassis. Background Art

[0002] Service robots can be divided into professional service robots and personal / household service robots. Service robots have a wide range of applications and are mainly engaged in maintenance, repair, transportation, cleaning, security, rescue, monitoring and other tasks.

[0003] In the freight logistics market, the use of AGV handling service robots for logistics handling work can not only effectively reduce human resource investment, but also enable the service robot to be accurately positioned by laying magnetic tracks, greatly improving the handling efficiency compared to traditional methods. However, the handling service battery has a short life and requires frequent charging, which is a problem that cannot be ignored for fast and efficient logistics operations. For some large warehouses and logistics centers, charging time will affect work efficiency and increase the company's investment cost for equipment. Therefore, after the handling is completed, the service robot battery is generally replaced to enable the service robot to quickly put into work. The battery of the service robot is mostly installed on its chassis. The cover is currently fixed by fixing screws, which is not convenient for the rapid replacement of the battery on the chassis. For this reason, we propose a service robot chassis. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] See also Figure 1-4 The utility model provides a technical solution for a service robot chassis: the service robot chassis includes a combined chassis 1, the combined chassis 1 includes an upper chassis 11 and a lower chassis 12, and also includes: a limiting component 2 arranged on a side of the upper chassis 11, and the upper chassis 11 and the lower chassis 12 are connected through the limiting component 2; a releasing component 3 arranged on a side of the lower chassis 12, and the tight connection between the upper chassis 11 and the lower chassis 12 is released through the releasing component 3.

[0027] A plurality of rectangular universal wheels 13 are fixedly provided at the lower end of the lower chassis 12. The universal wheels 13 can rotate freely and move to the specified position following the instructions of the service robot. This is the prior art and will not be elaborated on here. A battery compartment 14 is provided on the upper side of the lower chassis 12. Batteries are placed in the battery compartment 14. A rotating shaft 15 is rotatably connected between the upper chassis 11 and the lower chassis 12. The rotating shaft 15 is rotatably connected to the lower chassis 12, but can move downward a certain distance in the lower chassis 12.

[0028] The limiting assembly 2 includes a limiting bar 21, a moving bar 22 is arranged on one side of the limiting bar 21, a telescopic pile 23 is arranged between the moving bar 22 and the limiting bar 21, a groove matched with the moving bar 22 is opened on one side of the limiting bar 21, one end of the telescopic pile 23 is fixedly arranged in the groove, and the other end of the telescopic pile 23 is fixedly connected to one side of the moving bar 22, and one side of the moving bar 22 is arranged in a sloped surface, so that the moving bar 22 can smoothly enter the limiting bar 21 when it is squeezed by the side wall of the limiting groove 34.

[0029] The release assembly 3 includes a release bar 31, a moving column 32 is fixedly provided on one side of the release bar 31, and a limit spring 33 is sleeved on the outer wall of the moving column 32. The limit spring 33 is provided to reset the moving column 32. A limit groove 34 adapted to the limit bar 21 is provided on the upper surface of the lower chassis 12. The release bar 31 is slidably set in the lower chassis 12, one end of the moving column 32 passes through the side wall of the lower chassis 12, and the two ends of the lower chassis 12 are hollow. One end of the limit spring 33 is fixedly connected to the inner wall of the lower chassis 12, and the other end of the limit spring 33 is fixedly connected to the moving column 32. The limit assembly 2 and the release assembly 3 are both symmetrically arranged.

[0030] A limit assembly 2 and a release assembly 3 are provided to realize quick connection and release between the upper chassis 11 and the lower chassis 12. The upper chassis 11 and the lower chassis 12 are staggered by rotating the rotating shaft 15, which facilitates the replacement of batteries in the battery compartment 14, so that the service robot can be put into work quickly and the work efficiency is effectively improved; by providing a limit bar 21, a moving bar 22, a release bar 31 and a moving column 32, two relative moving columns 32 are used to press inward at the same time to release the limit of the limit bar 21, thereby avoiding the upper chassis 11 and the lower chassis 12 from being separated due to accidental touching of a single moving column 32.

[0031] When installing batteries on the service robot, first put the battery pack into the battery compartment 14, then rotate the upper chassis 11, and the upper chassis 11 will rotate with the lower chassis 12 through the rotating shaft 15. When the upper chassis 11 rotates to coincide with the lower chassis 12, press the upper chassis 11 downward, and the limit bar 21 at the lower end of the upper chassis 11 will first contact the limit groove 34 on the lower chassis 12, and the side wall of the limit groove 34 will contact the moving bar 22 on the limit bar 21, and the moving bar 22 will be squeezed to the limit. The telescopic pile 23 is also compressed at this time. When the upper chassis 11 continues to move downward until the limiting strip 21 completely enters the limiting groove 34, the moving strip 22 loses the resistance of the side wall of the limiting groove 34, so the telescopic pile 23 is reset. At this time, the moving strip 22 moves outward and is stuck inside the lower chassis 12. At this time, the upper chassis 11 and the lower chassis 12 cannot be rotated or separated by external force. The upper chassis 11 can also effectively protect the battery in the battery compartment 14 on the lower chassis 12.

[0032] When the battery of the service robot is exhausted and needs to be replaced, the movable column 32 is squeezed inward at the same time. The movable column 32 will drive the release bar 31 to squeeze the movable bar 22, and the movable bar 22 will move into the limit bar 21 again. At this time, the upper chassis 11 can be separated from the lower chassis 12 by lifting the upper chassis 11 upward and rotating it half a circle. At this time, the battery compartment 14 on the lower chassis 12 is exposed, so that the battery can be replaced quickly, and then the upper chassis 11 and the lower chassis 12 can be connected again through the above operation.

[0033] Embodiment 2:

[0034] See also Figure 5 The utility model provides a technical solution for the chassis of a service robot: the chassis of the service robot includes a battery compartment 14 provided on the upper side of a lower chassis 12, a rotating shaft 15 is rotatably connected between the upper chassis 11 and the lower chassis 12, a telescopic spring 16 is fixedly provided at the lower end of the rotating shaft 15, and the other end of the telescopic spring 16 is fixedly connected to the lower chassis 12.

[0035] This arrangement is to squeeze the moving column 32 inward at the same time, and the moving column 32 will drive the release bar 31 to squeeze the moving bar 22, and the moving bar 22 will move into the limit bar 21 again. At this time, there is no need to lift the upper chassis 11 upward. With the resetting of the telescopic spring 16, the upper chassis 11 can automatically move upward, which facilitates the operation procedure of a single operator to replace the battery in the chassis of the service robot, thereby further improving his work efficiency.
