Description

Technical Field

[0001] The utility model relates to the field of intelligent mobility-replacing robots, in particular to a quick-disassembly structure. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] In the field of mobility assistance, to make travel more convenient for people with limited mobility, the low-automatic properties of traditional wheelchairs are being updated to better assist people with limited mobility and better integrate them into their lives. Embodied intelligent robots are the product of a deep integration of embodied intelligence technology and intelligent mobility tools. They are no longer just a means of transportation, but rather an "intelligent entity" with autonomous perception, cognition, decision-making, and action capabilities, capable of assisting people with limited mobility (such as the elderly and people with disabilities) to move around in complex environments and complete daily tasks more safely, naturally, and proactively.

[0004] Some existing mobility robots have a foldable storage function, but for users, the weight of the folded device is still inconvenient to carry. When carrying it out, it is difficult to carry the entire mobility robot in the trunk of a car. When the entire device is placed in the trunk, it takes up a lot of space, making it difficult to properly arrange the space. Therefore, it is necessary to separate the chassis and seat of the mobility robot to enable quick disassembly. The existing quick-disassembly structure makes the assembly process complicated and the structural stability is poor after the two are quickly disassembled. Therefore, it is necessary to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a quick-release structure, which solves the problem of the existing quick-release structure as described in the background technology, in which the assembly process is complicated and the structural stability is poor after the chassis and seat of the mobility robot are quickly separated. The utility model is used for a mobility robot, and stably connects the seat and chassis of the mobility robot together, and can also realize the function of quickly separating the two. The structure is simple, stable and safe, ensuring that the seat will not shake when the user rides, providing a more comfortable experience.

[0006] In order to achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0009] The control mechanism includes a quick-release switch, a pull wire connected to the quick-release switch, a guide plate arranged on the connecting shaft, a clip arranged on one side of the limit claw, and a connecting piece arranged on the two limit claws;

[0010] The pull wire is connected to a connector, and the connector is connected to two limit claws. When the quick release switch drives the pull wire to retract, the limit claw rotates on the connecting shaft. When the quick release switch is released, the clip drives the limit claw to reset.

[0011] A guide and limit assembly is further provided between the transverse beam and the clamping seat. The guide and limit assembly includes a track seat provided on the transverse beam, a guide groove is provided on the track seat, and a guide column adapted to the guide groove is provided on the clamping seat.

[0024] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined in this application.

[0025] like Figure 1-Figure 7 The present invention is a quick-release structure, the main structure of which includes a transverse beam 1 and a snap-fit ​​seat 2 quickly connected to the transverse beam 1; the transverse beam 1 is provided with two snap-fit ​​seats 2 connected to the chassis of the mobility robot body, and the snap-fit ​​seat 2 is used to connect the seat and the backrest part, and the quick-release switch 7 below is set under the seat.

[0026] The clamping seat 2 is provided with a first limiting groove 3 and a second limiting groove 4, and the clamping seat 2 is provided with a connecting shaft 5. Two limiting claws 6 are rotatably connected to the connecting shaft 5. The limiting claws 6 are provided with a clamping groove, and the clamping groove is adapted to the diameter of the transverse beam 1. The clamping seat 2 is provided with a control mechanism, and the control mechanism drives the two limiting claws 6 to rotate synchronously to achieve the limitation and separation of the transverse beam 1.

[0027] The control mechanism includes a quick release switch 7, a pull wire 8 connected to the quick release switch 7, a guide plate 9 provided on the connecting shaft 5, a retaining spring 10 provided on one side of the limiting claw 6, and a connecting piece 11 provided on the two limiting claws 6;

[0028] One end of the pull wire 8 is connected to the quick-release switch 7, and the other end is connected to the connecting piece 11. The connecting piece 11 is connected to the two limit claws 6. Pressing the quick-release switch 7 drives the pull wire 8 to retract, and at the same time drives the limit claw 6 to rotate on the connecting shaft 5, so that the limit claw 6 releases the limit between the transverse beam 1. At this time, the seat as a whole can be separated from the drive chassis. When the quick-release switch 7 is released, the pull wire 8 is relaxed and reset under the combined action of its own elastic force and the retaining spring 10.

[0029] If the quick-release structure described above is used, the connection will be unstable and the limiting effect will be poor, affecting the safety of passengers. In addition, after the seat is separated from the chassis, it will not have a guiding function during installation. Therefore, further improvements are required:

[0030] A guide and limit assembly is also provided between the transverse beam 1 and the adapter 2. The guide and limit assembly includes a track seat 12 disposed on the transverse beam 1. The track seats 12 are located on either side of the adapter 2. The track seats 12 are provided with guide grooves 13, and the adapter 2 is provided with guide posts 14 that mate with the guide grooves 13. The guide grooves 13 limit and guide the guide posts 14, making installation of the seat assembly to the chassis much faster. During installation, the seat can be quickly positioned according to the trajectory of the guide grooves 13. To further enhance the stability of the quick-release structure, further improvements have been made:

[0031] The bottom of the guide groove 13 is an inclined surface. The connector 2 is provided with multiple limiting grooves, with the opening of the first limiting groove 3 facing the ground and the opening of the second limiting groove 4 facing the rear. After the seat and base are assembled, when the center of gravity of the seat is forward, the inclined bottom of the guide groove 13 allows the opening of the first limiting groove 3 and the locking groove of the limiting claw 6 to work together to limit the position. When the center of gravity of the seat is rearward, the opening of the second limiting groove 4, the inclined edge of the guide groove 13, and the limiting claw 6 work together to limit the position, thereby achieving more uniform force distribution and greater stability.

[0032] The guide groove 13 and the groove body also have a self-locking limit function in the lifting direction of the chassis and the seat. According to the trajectory of the guide groove 13 in the instruction manual, the guide column 14 is directly limited at the bottom of the inclined surface of the guide groove 13. Therefore, after the limiting claw 6 is released from the limit, the two cannot be separated by directly lifting the seat as a whole. It is necessary to rotate with the second limiting groove 4 as the fulcrum to unscrew the first limiting groove 3 from the transverse beam 1. At the same time, the guide column 14 is synchronously rotated to the top of the inclined surface, and then lifted according to the trajectory of the guide groove 13 to separate the two.
