Specifically, as shown in fig. 4, a front view of the electrical connection apparatus 10 in the mounting structure 100 of the electrical connection apparatus provided by the present invention is shown. The mounting projection 1212 on the second vertical surface 102 of the electrical connection apparatus 10 forms two horizontal mounting surfaces 1215 on a side surface near the pivot 1211, and a mounting arc 1214 disposed around the pivot 1211 between the two horizontal mounting surfaces 1215. The two horizontal mounting surfaces 1215 are disposed perpendicular to the second vertical surface 102, and the second vertical surface 102 needs to be attached to the outside side surface of the armrest 200 when the electrical connection apparatus 10 is fixed to the armrest 200. Meanwhile, the mounting arc surface 1214 positioned between the two horizontal mounting surfaces 1215 has three first inclined surfaces 1214a, circular arc connecting surfaces 1214b and second inclined surfaces 1214c which are connected in sequence. The first inclined surface 1214a and the second inclined surface 1214c are symmetrically disposed with respect to each other. The highest point of the first inclined surface 1214a and the highest point of the second inclined surface 1214c are respectively located at two sides of the pivot 1211, and the lowest point of the first inclined surface 1214a and the lowest point of the second inclined surface 1214c are respectively connected to two ends of the arc connecting surface 1214b and located at the bottom of the pivot 1211. The installation arc surface 1214 of the electrical connection device 10 is used to abut against the bottom of the horizontal installation block 20, and the relative rotation between the pivot 1211 and the horizontal installation block 20 is used to offset the inclination between the upper armrest 200 of the electric wheelchair or electric scooter and the horizontal plane, so that the horizontal line 103 of the electrical connection device 10 is always horizontal without being inclined with the armrest 200.

Further, as shown in fig. 3, in the mounting structure 100 provided by the present invention, the horizontal mounting block 20 includes a pivot hole 21 pivoted to the electrical connection device 10, a first abutting surface 22 abutting against the armrest 200, and a second abutting angle 23 abutting against the mounting arc surface 1214.

Generally, since the height of the front end of the armrest 200 of the electric wheelchair or the electric scooter is higher than the height of the rear end, when the electrical connection device 10 is fixed to the armrest 200 of the right hand, the second contact angle 23 rotates from the circular arc connection surface 1214b to the second inclined surface 1214c with the rotation of the horizontal mounting block 20, and the inclination of the armrest 200 is offset by the rotation of the horizontal mounting block 20. When the electrical connection apparatus 10 is fixed to the left-hand armrest 200, the second abutting angle 23 rotates from the circular arc connecting surface 1214b to the first inclined surface 1214a as the horizontal mounting block 20 rotates. Therefore, the mounting structure 100 of the electrical connection device provided by the present invention is not only suitable for mounting the right-hand armrest 200, but also suitable for mounting the left-hand armrest 200.

As shown in fig. 1, an armrest 200 of an electric wheelchair or an electric scooter includes an arm pad 210 and a frame 220 provided below the arm pad 210 to connect the arm pad 210 to a cart body. The supporting bolt 30 of the mounting structure 100 provided by the present invention is abutted to the frame 220, and is used for ensuring that the whole electrical connection device 10 does not incline to two sides in the vertical direction, so as to ensure that the vertical line 104 of the electrical connection device 10 is always in a vertical state. In the present embodiment, the second connecting portion 122 includes two pairs of mounting holes 1221 disposed on the second vertical surface 102 of the electrical connection device 10 at different heights, where two mounting holes 1221 at the same height are a set of the second connecting portion 122, and each mounting hole 1221 can be used to fix one supporting bolt 30. Four supporting bolts 30 can be fixed to two sets of mounting holes 1221 of co-altitude not, realize that the skeleton 220 butt below the handrail 200 of two kinds of co-altitudes uses, can satisfy and install on the handrail 200 of most electronic wheelchair or electronic car of riding instead of walk on the market and use.

At this time, the second support point added by the support bolt 30 forms a first support point with the second vertical surface 102 of the electrical connection apparatus 10 and the arm pad 210 in the armrest 200, and the two support points form a stable support on the vertical surface, thereby preventing the entire electrical connection apparatus 10 from tilting in the vertical direction. When installed, as shown in fig. 6, the bottom of the supporting bolt 30 is fixed in the installation hole 1221, and the top of the supporting bolt 30 abuts against the armrest 200. And the supporting bolt 30 is fixed to the mounting hole 1221 by the external thread of the bottom of the supporting bolt 30 and the internal thread of the mounting hole 1221 being engaged with each other. Therefore, as the distance between the framework 220 of the armrest 200 and the mounting protrusion 1212 of the electrical connection device 10 is different, the distance between the support bolt 30 and the framework 220 can be adjusted by rotating the depth of the support bolt 30 in the mounting hole 1221, so that the top of the support bolt 30 can be always attached to the framework 220, and the support bolt 30 can be used on different armrests 200.

Further, as shown in fig. 4, the present invention provides the mounting structure 100, wherein the third connecting portion 123 of the mounting portion 12 includes at least one inlet hole 1231 for the rope 41 to pass through and at least one outlet hole 1232 communicated with the inlet hole 1231 for the rope 41 to pass through. The inlet hole 1231 is located below the outlet hole 1232, so that the strap 40 needs to be inserted into the electrical connection device 10 through the inlet hole 1231 located below and to exit out of the electrical connection device 10 through the outlet hole 1232 located above when passing through the electrical connection device 10. The third connecting portion 123 is two mutually connected waist-shaped holes disposed on the second vertical surface 102, and the width of the waist-shaped hole is slightly wider than that of the strap 40, so as to ensure that the strap 40 can pass through the third connecting portion 123 well. Fig. 7 is a perspective view of the strap 40 as it passes through the electrical connector apparatus 10. The string 41 of the strap 40 is inserted into the electrical connection device 10 from the inlet hole 1231 on the mounting protrusion 1212 and passes all the way to the outlet hole 1232 above along the dotted line position, and the end of the string 41 of the strap 40 is continuously pulled upward after passing through the outlet hole 1232, passes through the loop 42 of the strap 40, and achieves the connection of the strap 40 and the electrical connection device 10, and simultaneously achieves the loop winding of the strap 40, and passes the armrest 200 of the electric wheelchair or the electric scooter through the loop space formed by the strap 40, and gradually pulls the free end of the string 41, so that the loop space gradually reduces to the size of the armrest 200, thereby fixing the electrical connection device 10 on the armrest 200.

Specifically, as shown in fig. 4, in the present embodiment, the third connecting portion 123 of the mounting portion 12 includes three inlet holes 1231 provided in parallel with each other on the mounting boss 1212 and one outlet hole 1232 provided on the second vertical surface 102, the outlet hole 1232 being located above the inlet holes 1231. The inlet holes 1231 of three different heights are all located on the mounting protrusion 1212, and the inlet holes 1231 of three different heights are all communicated with the outlet hole 1232 located above, so that the binding band 40 can enter from the inlet holes 1231 of different heights and then exit from the outlet hole 1232. The different height inlet holes 1231 allow the electrical connection apparatus 10 to be adapted for use with different armrests 200. Since the shape, structure, width, thickness, and shape and thickness of the armrest 200 of the electric wheelchair or electric scooter are different, the three different height inlet holes 1231 provided on the second vertical surface 102 of the electric connection device 10 can be used in combination with the strap 40 to stably connect different armrests 200 and electric connection devices 10. In the three parallel inlet holes 1231, the lower inlet hole 1231 is suitable for the handrail 200 with a larger thickness, the upper inlet hole 1231 is suitable for the handrail 200 with a smaller thickness, and different inlet holes 1231 can meet different handrail 200 designs. The strap 40 may be threaded through different inlet holes 1231 depending on the different armrests 200.

Specifically, as shown in fig. 4, the present invention provides the mounting structure 100 in which the inlet hole 1231 of the third connecting portion 123 forms a guide slope 1234 inside the mounting protrusion 1212, which provides support for the string 41. As shown in fig. 7, the guide slope 1234 is a slope inclined from the inlet hole 1231 toward the outlet hole 1232 side, so that the string 41 of the strap 40, after entering the inlet hole 1231, facilitates the penetration and exit of the string 41 in the third connecting portion 123 as the direction of the guide slope 1234 moves to the outlet hole 1232.

Further, as shown in fig. 5, the present invention provides the mounting structure 100 in which the second vertical surface 102 of the electrical connection apparatus 10 is further provided with a wire guide groove 13 at a side surface of the mounting portion 12. The wire groove 13 extends from the second vertical surface 102 toward the side connected with the armrest 200, and a groove for embedding a wire is formed therein, a wire can be arranged in the wire groove 13, and is electrically connected with the electric connector 11 in the electric connection device 10 through the wire, and the wire is guided to the bottom of the armrest 200 through the wire groove 13 and is electrically connected with the controller located above the armrest 200, so that the wire is more compact and gathered.

The mounting structure 100 of the electrical connection device provided by the invention can be applied to the armrests 200 of most electric wheelchairs or electric vehicles on the market, is convenient for installers to independently, quickly and conveniently mount the electrical connection device 10 without changing the existing armrests 200 of the electric wheelchairs or electric vehicles, the installation and fixation of the electrical connection device 10 can be completed, the self-adaptation to different handrail 200 structures can be realized, the left handrail 200 and the right handrail 200 can be flexibly installed, the electrical connector 11 on the electrical connection device 10 is ensured to be always kept in a horizontal and vertical arrangement state, thereby ensuring that the electrical connection device 10 can be accurately butted with the device to which the electrical connection device is butted, so that the electrical connection device 10 can be always kept in contact with the butting device in a vertical state when the electrical connection device is butted with the butting device, and ensuring the stability in electrical connection.

As shown in fig. 7 to 10, the present invention also provides an installation method of the electrical connection apparatus. The mounting method comprises the mounting structure 100 of the electric connection equipment, and can be applied to mounting the electric connection equipment on the handrail of the electric wheelchair or the electric scooter. In the present embodiment, an electric wheelchair is exemplified as the mounting body. As shown in fig. 10, the method for mounting an electrical connection device according to the present invention includes the steps of:

s1, the horizontal mounting block 20 is pivoted on the first connecting part 121 of the electrical connecting device 10, the supporting bolt 30 is fixed on the second connecting part 122 of the electrical connecting device 10, and the rope belt 41 of the binding belt 40 passes through the third connecting part 123 of the electrical connecting device 10;

as shown in fig. 7, it is a schematic perspective view of the mounting structure 100 of the electrical connection apparatus when the step S1 is completed. In the step S1, it is necessary to fix the horizontal mounting block 20, the support bolt 30, and the strap 40 of the mounting structure 100 to the electrical connection device 10, respectively. During installation, the horizontal mounting block 20 may be inserted, the supporting bolt 30 may be locked into the mounting hole 1221, and the strap 40 may be finally inserted through the third connecting portion 123. It is also possible to first pass the strap 40 through the third connecting portion 123, lock the support bolt 30 into the mounting hole 1221, and finally insert the horizontal mounting block 20 into the pivot 1211. That is, in the S1 step, the fixing order of the horizontal mounting block 20, the supporting bolt 30, and the binding band 40 may be randomly arranged in the front-rear direction.

In step S1, when the horizontal attachment block 20 is fixed to the first connection part 121, it is necessary to confirm whether the electrical connection device 10 is fixed to the right-hand armrest 200 or the left-hand armrest of the electric wheelchair, and determine the position of the horizontal attachment block 20 placed in the first connection part 121 according to the direction in which the armrest 200 is installed. If the electrical connection device 10 is disposed on the right armrest 200, the height of the front side of the horizontal mounting block 20 should be higher than the height of the rear side, and at this time, the second abutting angle 23 of the horizontal mounting block 20 abuts against the second inclined surface 1213c of the mounting arc surface 1214, so that the first abutting surface 22 of the horizontal mounting block 20 can abut against the bottom surface of the arm pad 210 of the right armrest 200, and the whole electrical connection device 10 can be kept in a horizontal state all the time. If the electrical connection device 10 is disposed on the left armrest 200, the height of the front side of the horizontal mounting block 20 should be lower than the height of the rear side, and at this time, the second abutting angle 23 of the horizontal mounting block 20 abuts against the first inclined surface 1213a of the mounting arc surface 1214, so that the first abutting surface 22 of the horizontal mounting block 20 can abut against the bottom surface of the arm pad 210 of the left armrest 200, and the whole electrical connection device 10 can be kept in a horizontal state all the time.

In the step S1, the external thread of the bottom of the jack bolt 30 is only screwed into the mounting hole 1221 of the second connecting portion 122, and the depth of the jack bolt 30 in the mounting hole 1221 is not adjusted.

In the S1 step, it is necessary to select the position of the inlet hole 1231 through which the strap 40 is inserted according to the entire height of the armrest 200. If the height of the armrest 200 is greater, the strap 40 is threaded through the lower inlet 1231 (i.e., the inlet 1231 that is farthest from the outlet 1232 is selected) and then threaded out through the outlet 1232. If the height of the armrest 200 is small, the strap 40 is threaded through the inlet hole 1231 located higher (i.e., the inlet hole 1231 closest to the outlet hole 1232 is selected) and then threaded out through the outlet hole 1232. If the height of the armrest 200 is moderate, the inlet hole 1231 in the middle of the mounting protrusion 1212 can be selected to pass through and then out through the outlet hole 1232.

S2: attaching the second vertical surface 102 of the electrical connection device 10 to the outer side surface of the handrail 200, attaching the horizontal mounting block 20 to the bottom surface of the handrail 200, winding the string 41 of the binding band 40 around the handrail 200 and passing the string 41 of the binding band 40 through the loop 42 of the binding band 40;

as shown in fig. 8, the mounting structure 100 is a schematic perspective view of the outside of the armrest 200 after the step S2 is completed. In step S2, it is necessary to attach the second vertical surface 102 of the electrical connection device 10 to the vertical surface of the outer side of the armrest 200, so that a first contact point in the vertical direction is formed between the electrical connection device 10 and the armrest 200, and the two are completely attached, then attach the first abutting surface 22 of the horizontal mounting block 20 to the bottom surface of the armrest 200, so that the first contact point in the horizontal direction is formed, the first contact point in the vertical direction and the first contact point in the horizontal direction are perpendicular to each other, and after forming a stable support, pass the string 41 of the strap 40 through the loop 42, so that the strap 40 forms a closed loop around the armrest 200.

S3: the string 41 passing through the buckle 42 is reversely stretched so that the support bolt 30 is closely attached to the handrail 200, and then the string 41 is locked to the handrail 200.

As shown in fig. 9, the mounting structure 100 is a schematic perspective view of the outside of the armrest 200 after the step S3 is completed. In step S3, the string 41 is first pulled reversely so that the mounting protrusion 1212 of the electrical connection device 10 is drawn toward the side of the armrest 200, and the supporting bolt 30 on the mounting protrusion 1212 can abut against the frame 220 of the armrest 200 while the mounting protrusion 1212 is drawn toward the armrest. In step S3, two support bolts 30 of different heights are selected according to the position of the skeleton 220 in the armrest 200. If the arm pad 210 on the armrest 200 is thick and the frame 220 is located low, the support bolt 30 at the bottom of the mounting protrusion 1212 is selected to abut against the frame 220 for support, forming a second contact point in the vertical direction. If the arm pad 210 on the armrest 220 is thin and the frame 220 is located at a high position, the support bolt 30 at the top of the mounting protrusion 1212 is selected to abut against the frame 220 for support, forming a second contact point in the vertical direction. As shown in fig. 6, in the present embodiment, the supporting bolt 30 selects two mounting holes 1221 located at the top of the mounting protrusion 1212 for fixing.

In step S3, it is necessary to adjust the depth of the supporting bolt 30 in the mounting hole 1221 by rotating the supporting bolt 30, thereby adjusting the distance between the mounting protrusion 1212 and the frame 220 so that the first contact point of the second vertical mounting surface 102 of the electrical connection apparatus 10 in the vertical direction and the second contact point on the supporting bolt 30 are on the same vertical plane.

In step S3, the strap 41 of the strap 40 is fastened to the handrail 200 differently due to the material selected for the strap 40. In this embodiment, as shown in fig. 7, the string 41 of the binding band 40 has the loop surface 412 and the hook surface 411 of the hook and loop fastener, and in the step S3, after the string 41 with the loop surface 412 of the hook and loop fastener 42 is passed through, the string 41 with the hook and loop surface 411 of the hook and loop fastener is attached to each other after being stretched in the opposite direction, so that the binding band 40 and the electrical connection device 10 are locked on the outer circumferential surface of the armrest 200, and the horizontal line 103 of the electrical connection device 10 can be kept in the horizontal position, and the vertical line 104 is in the vertical position. If the binding band 40 made of other different materials is used, the corresponding locking method is selected to fix the electrical connection device 10.

According to the installation method of the electrical connection equipment, the installation structure 100 of the electrical connection equipment is adopted, the electrical connection equipment 10 can be suitable for being installed and used on the handrails 200 of most electric wheelchairs or electric mobility scooter on the market in a mode of winding the binding bands 40, the installation method is simple, easy to operate and firm in installation, the installation and the fixation of the electrical connection equipment 10 and the handrails 200 of the electric wheelchairs or the electric mobility scooter can be completed without any tools, and the electrical connection equipment 10 can be ensured to be in a horizontal and vertical state all the time by adapting to the inclination angle of the handrails 200 after installation.
