As shown in fig. 1, the full rail charging type shifting machine of the present embodiment includes a rail 1 and a shifting device 2 slidably disposed on the rail 1.

Specifically, an upper insulation rail 10 and a lower insulation rail 11 extending along the length direction of the rail 1 are respectively formed on the rail 1, wherein the upper insulation rail 10 and the lower insulation rail 11 are spaced up and down and are respectively formed with a sliding groove.

In this example, a positive conductive bar 3 and a negative conductive bar 4 extending along the length direction thereof are respectively mounted in the sliding grooves of the upper insulating rail 10 and the lower insulating rail 11.

Specifically, the positive conductive strip 3 and the negative conductive strip 4 are both copper sheets and are fixed at the bottom of the sliding groove. Thus, leakage or short circuit caused by the power-on of the positive conductive strip 3 and the negative conductive strip 4 is avoided.

As shown in fig. 2 and fig. 3, the shifting apparatus further includes a charging seat 5 fixed on the shifting apparatus 2, a positive contact 6 and a negative contact 7 formed on the charging seat 5, and a conductive wire, wherein the positive contact 6 and the negative contact 7 are in one-to-one correspondence and divided into a plurality of groups, each group of two positive contacts 6 and two negative contacts 7 are separated and respectively slide and elastically abut against the corresponding positive conductive strip 3 and negative conductive strip 4, and the conductive wire respectively communicates each group of positive contacts 6 and negative contacts 7 with the corresponding charging circuit.

As shown in fig. 4, the charging seat 5 includes a connecting body 50 fixedly connected to the displacement device 2, and a plurality of connecting seats 51 disposed on the connecting body 50, wherein each connecting seat 51 is formed with an upper mounting channel t1 and a lower mounting channel t2 disposed at an interval, and the positive contact 6 and the negative contact 7 respectively elastically protrude from the end portions of the upper mounting channel t1 and the lower mounting channel t 2. Thus, the requirement of elastic interference between the positive contact 6 and the negative contact 7 is satisfied.

The connecting socket 51 comprises a first insulating block 511 and a second insulating block 512 which are mutually detached, wherein semicircular holes are respectively formed on the first insulating block 511 and the second insulating block 512, and the semicircular holes are spliced to form an upper mounting channel t1 and a lower mounting channel t 2.

The positive contact 6 and the negative contact 7 have the same structure, and both comprise a tongue bar s1 movably arranged in the upper mounting channel t1 or the lower mounting channel t2, a tongue s2 positioned at the outer end of the tongue bar s1 and capable of abutting against the positive conductive strip 3 or the negative conductive strip 4, the shifter further comprises an elastic member 8 arranged in the upper mounting channel t1 and the lower mounting channel t2, and socket joints 9 which correspond to the elastic members 8 one by one and are fixed on the first insulating block 511 or the second insulating block 512, wherein two end parts of the elastic member 8 respectively abut against between the tongue bar s1 and the socket joints 9. Thus, not only is the communication of the charging circuit convenient, but also the contact can be kept all the time along with the synchronous movement of the shifting device, so that the full-orbit charging can be realized.

The wire comprises a wire body and wire connectors formed at two ends of the wire body, wherein the wire connectors can be inserted from the jack connectors and conduct the charging circuit. The plug-in type is convenient to disassemble and assemble. This plug-in mode is also quite common, such as the plug-in connector and the cord body of a headset.

The wire terminal is inserted into the socket terminal and pushes the tongue s2 against the elastic member to abut on the positive conductive strip 3 or the negative conductive strip 4. Here, two implementation modes can be formed: 1. the tongue is originally attached to the positive conductive strip or the negative conductive strip, and the tongue relatively abuts against the conductive strips through the insertion of the line connectors so as to ensure the contact stability; 2. the tongue and the positive conductive strip or the negative conductive strip have a gap, that is, the tongue does not contact the positive conductive strip or the negative conductive strip, if charging is needed, the wire connector is inserted into the jack connector, and the elastic piece pushes the tongue to relatively abut against the conductive strips, so as to implement contact charging.

In this case, the second mode is adopted, so that when charging is required, the wire connector can be plugged and the charging loop can be communicated; when the charging is not needed, the wire joint is pulled out, the contact and the conductive strip are not contacted, and the contact and the conductive strip cannot be abraded in the displacement process.

Tongue s2 includes abutting end s20, and curved corners s21 on opposite sides of abutting end s20, wherein abutting end s20 and/or curved corners s21 are in line contact or surface contact with positive conductive strip 3 or negative conductive strip 4. This minimizes sliding wear.

The connection socket 51 further includes protection isolation lugs 513 respectively disposed on the first and second insulation blocks 511 and 512, and the arc-shaped corners s21 of the tongues s2 are respectively located in the protection isolation lugs 513. The tongue s2 is prevented from causing accidental leakage in the sliding process, and the external device is prevented from being clamped between the contact and the conductive strip to cause short circuit or short circuit of the charging loop.

In summary, the present embodiment has the following advantages:

1. the formed charging loop can synchronously move along with the movement of the shifting machine and keeps the communication of the charging loop, so that full-orbit charging is implemented;

2. a plurality of charging loops are formed, even if one charging loop is short-circuited or broken, other charging loops are still communicated to keep charging;

3. under the plugging and conducting of the wire joint, the contact stability between the contact and the bus bar is further ensured, and meanwhile, the contact and the bus bar can be selected to be relatively separated according to actual needs, so that when charging is not needed, contact abrasion between the contact and the bus bar cannot be caused in the implementation moving process of the shifting machine;

4. the formed positive and negative electrodes are isolated, so that electric leakage or short circuit caused by the electrification of the positive conductive strips and the negative conductive strips is avoided, and the full-rail charging is safely implemented.

The present invention has been described in detail above, but the present invention is not limited to the above-described embodiments. All equivalent changes and modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
