Description

Inlaid joint structure and mobile carrier

The invention relates to an inlaid joint structure and a mobile carrier, and particularly relates to an inlaid joint structure that quickly connects the lower body and the upper body of the mobile carrier.

At present, the modular detachable car (Rinspeed SNAP) adopts a skateboard chassis structure, which is designed on the basis of the body on frame structure, and the chassis can carry different application functions on the body. For shared and shared mobile applications, it uses a tenon structure to connect the upper body. However, fast connection of electrical signals and physical circuits is a problem. The solution is to equip the modular upper body with an independent control computer and power supply, so that the upper and lower body can be combined without signal connection. However, this move will inevitably increase the weight and cost of the upper body because it reduces the components shared by the upper and lower body modules.

The bottom box of the shock seat 1272. The lower joint elastic material seat 122 overlaps the lower joint socket 121, the shock isolation element 126 is arranged between the shock isolation seat top cover 1271 and the rigid material seat annular bottom box 1272, and the shock isolation seat top cover 1271 surrounds The lower joint elastic material seat 125 is bonded, and the shock isolation seat bottom box 1272 is fixed to the bottom plate 124 of the download tool.

The upper joint elastic material seat 112 and the lower joint elastic material seat 122 are made of elastic material, such as rubber. The shock isolation seat top cover 1271 and the shock isolation seat bottom box 1272 are made of rigid materials, such as metal materials.

Taking the dashed line 24 in FIG. 2 as the boundary, the upper joint 11 and the lower joint 12 of the inlaid joint structure 1 are installed on an upper body 21 and a lower body 22 via the upper carrier bottom plate 114 and the carrier bottom plate 124 respectively.

The lower joint 12 of the inlaid joint structure 1 is installed in the assembly of the lower body 21. The shock-absorbing element 126 is an indispensable shock-absorbing element for the body on the chassis (body on frame) structure. In order to reduce the transmission of the vibration of the lower body 22 to the upper body 21, the vibration isolation element 126 is arranged between the shock isolation seat top cover 1271 and the shock isolation seat bottom box 1272, that is, located between the upper carrier bottom plate 114 and Between the carrier bottom plates 124, the annular shock-isolation seat bottom box 1272 is fixed (for example, welded or glued) to the carrier bottom plate 124, and the annular shock-isolation seat top cover 1271 abuts the upper carrier bottom plate 21. For example, the seismic isolation element 126 may have a ring design, the seismic isolation seat top cover 1271 and the seismic isolation seat bottom box 1272 may also have a ring design, and the ring-shaped seismic isolation element 126 is housed in the seismic isolation seat top cover In the annular space defined between 1271 and the bottom box 1272 of the shock isolation seat.

When the upper body 21 and the lower body 22 are joined, one of the upper body 21 or the lower body 22 can be selected, and the upper joint fixing member 113 and the lower joint fixing member 123 (such as a plurality of bolts and nuts) can be used in one direction. ) Or other fixing methods restrict the relative positional relationship between the carrier bottom plate 114 and the carrier bottom plate 124 on the inlaid joint structure 1, The purpose of structural connection, shock absorption, impact resistance and easy disassembly and assembly of the upper body 21 and the lower body 22 is achieved. Please refer to FIG. 3, the shock isolation element 126 can be designed with superior rubber, adjustable damping, air spring, etc., and the inlaid joint structure 1 can withstand the transmission of road forces for different load adjustments.

4a and 4b are schematic cross-sectional exploded and combined diagrams of the upper joint and the lower joint of the mosaic joint structure according to an embodiment of the present invention. 4a and 4b, when the upper joint 11 and the lower joint 12 are joined, the opposite surfaces 1120 and 1220 of the upper joint elastic material seat 112 and the lower joint elastic material seat 122 conflict with each other. The upper joint elastic material seat 112 has a stepped cross-section 1122 for restraining overlap with the upper joint socket 111. The lower joint elastic material seat 121 also has a stepped cross section 1222 for restraining overlap with the lower joint socket.

Please refer to FIG. 4b again. When the upper joint 11 and the lower joint 12 are joined, the opposite surfaces 1120 and 1220 of the upper joint elastic material seat 112 and the lower joint elastic material seat 122 conflict with each other. The upper joint elastic material seat 112 and the lower joint elastic material seat 122 are partially designed with the recesses 1121 and 1221 to make the rigidity lower, and the lower rigid part can absorb the vibration of the lower body 22. Furthermore, the upper joint magnet 115 and the lower joint magnet 125 are mounted on the opposite surfaces of the upper joint elastic material seat 112 and the lower joint elastic material seat 122 (for example, having a plurality of concave holes 1123 and 1223). The upper joint magnet 115 and the lower joint magnet 125 may be permanent magnets or electromagnet designs. The adsorption force between the upper joint magnet 115 and the lower joint magnet 125 must be greater than the vibration of the lower body 22. For example, the adsorption force between the upper joint magnet 115 and the lower joint magnet 125 must be greater than the upper joint elastic material seat 112 The partial modeling recesses 1121 and 1221 of the lower joint elastic material seat 122 absorb the force generated by the vibration of the lower body 22. Therefore, during a driving process of a mobile vehicle (including the upper body 21 and the lower body 22), the upper joint elastic material seat 112 and the lower joint elastic material seat 122 will not be separated, together with the inlaid The upper joint socket 111 and the lower joint socket 121 will not be separated.

Since the upper joint socket 111 and the lower joint socket 121 will not be separated, the upper joint socket 111 and the lower joint socket 121 will be joined together, And has floating and anti-seismic effects. Furthermore, the lower connector socket 121 and the upper connector socket 111 can be male and female sockets. The upper vehicle electrical connector 211 and the download vehicle electrical connector 221 fixed in the upper connector socket 111 and the lower connector socket 121 can be tightly connected to each other. In the mobile vehicle (including the upper body 21 and the lower body 22) In the process, the transmitted vibration will only cause the upper carrier electrical connector 211 and the downloader electrical connector 221 to vibrate up and down in the dashed rectangle 20 (shown in FIG. 4b).

In addition, please refer to FIG. 4a again, when the upper joint 11 and the lower joint 12 are not joined, that is, before the lower joint 12 is joined to the upper joint 11, the opposite surface 1220 of the lower joint elastic material seat 122 and the spacer There is a height difference H between the top surfaces 1270 of the top cover 1271 of the shock seat. When the upper joint 11 and the lower joint 12 are joined, the opposite surfaces 1120 and 1220 of the upper joint elastic material seat 112 and the lower joint elastic material seat 122 conflict with each other, and the height difference H can make the lower joint elastic material seat 122 provides elasticity after compression, and the design of the partial shape depression 1221 of the lower joint elastic material seat 122 can increase the shock-absorbing and cushioning effect.
