DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0028] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0029] This embodiment mainly describes an off-road motorcycle with a motor battery in the middle and out the side, as follows:

[0030] like Figures 1 to 8 As shown, an off-road motorcycle with a motor and battery in the middle and out of the side comprises a frame 1, a motor assembly 2 and a battery assembly 3 mounted on the frame 1, the frame 1 comprises a bracket 11 and a main beam 12, the upper end of the bracket 11 is fixedly connected to the main beam 12 and encloses the main beam 12 to form an installation space 4, the motor assembly 2 and the battery assembly 3 are located in the installation space 4 from bottom to top, and the installation space 4 comprises a first installation assembly 5 and a second installation assembly 6 arranged on the bracket 11, the motor assembly 2 is detachably arranged on the first installation assembly 5, and the first installation assembly 5 abuts against and limits the two ends of the motor assembly 2 and fixes it while dragging its bottom to prevent the motorcycle from being moved while driving. The vibration during the process causes the motor assembly 2 to shake and escape from the installation space 4. The second installation assembly 6 is arranged above the first installation assembly 5. The second installation assembly 6 has support limit platforms 61 on both sides. The battery assembly 3 is detachably arranged on the second installation assembly 6 and abuts against the support limit platforms 61. The support limit platforms 61 support the battery assembly 3 and limit the battery assembly 3 from sliding forward and backward to prevent the battery assembly 3 from sliding forward and backward due to inertia when the motorcycle brakes suddenly during use. After installation, the motor assembly 2 is mainly supported by the first installation assembly 5, and the battery assembly 3 is supported by the second installation assembly 6, and the support area is large and the structural stability is strong.

[0031] like Figures 4 to 8 As shown, the first mounting assembly 5 includes a first support arm 51 and a second support arm 52 respectively arranged at both ends of the motor assembly 2, the first support arm 51 and the second support arm 52 are respectively fixed to the two ends of the motor assembly 2 and abut against the two ends of the motor assembly 2 to limit the two ends of the motor assembly 2, and the fixing method is specifically that the upper end surfaces of the first support arm 51 and the second support arm 52 are both arc-shaped openings 8, both ends of the arc-shaped opening 8 of the first support arm 51 are provided with first connecting holes 511, and both ends of the arc-shaped opening 8 of the second support arm 52 are provided with second connecting holes 521, and one end of the motor assembly 2 close to the first support arm 51 is provided with a connecting hole extending toward the first connecting hole 511 The motor assembly 2 has a first fixing hole 21 corresponding to the first connecting hole 511, and the other end of the motor assembly 2 has a second fixing hole 22 corresponding to the second connecting hole 521. The second fixing hole 22 is embedded in the motor. The first fixing hole 21 and the second fixing hole 22 can be threaded holes. During installation, the first connecting hole 511 is aligned with the first fixing hole 21, and the second connecting hole 521 is aligned with the second fixing hole 22. The bolt passes through the first connecting hole 511 and the end of the first fixing hole 21 and is fastened and fixed by a nut. After the screw passes through the second connecting hole 521 and the second fixing hole 22, the two sides of the motor assembly 2 are fixed to the first support arm 51 and the second support arm 52, respectively.

[0032] like Figure 6As shown, the first mounting assembly 5 also includes a third support arm 53, which is disposed between the first support arm 51 and the second support arm 52, and the third support arm 53 has an arc-shaped opening 8 adapted to the motor, and the bottom portion of the motor assembly 2 rests against the inner wall of the arc-shaped opening 8 to support the bottom of the motor assembly 2, and the main weight of the motor assembly 2 mainly falls on the third support arm 53, so that the third support arm 53 shares the support strength of the first support arm 51 and the second support arm 52 on the motor assembly 2, further enhancing the stability of the motor assembly 2, and avoiding the problem that the motor assembly 2 is supported only by the connection point between the first support arm 51 and the second support arm 52, resulting in the motor assembly 2 falling off and being damaged due to loose screws.

[0033] Specifically, both ends of the arc-shaped opening 8 of the third support arm 53 have connecting columns 531 extending toward the second support arm 52. The two connecting columns 531 are connected to the lower side of the second support arm 52 by screws. When the motor assembly 2 needs to be disassembled, replaced or repaired, the second support arm 52 can be disassembled from the two connecting columns 531 to separate the second support arm 52 from the third support arm 53, and one side of the third connecting arm 7 of the motor assembly 2 can be taken out, which makes disassembly simple.

[0034] Specifically, the bracket 11 has a first cross beam 111 and a second cross beam 112. One end of the first support arm 51 and the third support arm 53 are connected to the first cross beam 111, and the other end is connected to the second cross beam 112. The motor assembly 2 is located between the first cross beam 111 and the second cross beam 112. A vent 113 is formed at the bottom of the motor for heat dissipation. When the motor assembly 2 generates heat during use, the wind from the vent 113 can quickly dissipate the heat of the motor assembly 2.

[0035] like Figure 6As shown, the second mounting assembly 6 includes two groups of support plates 62 arranged on the bracket 11 and the above-mentioned support limit platform 61, the two groups of support plates 62 are respectively located on the front and rear sides of the bracket 11, each group of support plates 62 has two and are respectively arranged on both sides of the bracket 11, and the two groups of support plates 62 are provided with third connecting holes 63, and connecting plates 31 are provided on both sides of the bottom of the battery assembly 3. Fourth connecting holes 32 corresponding to the third connecting holes 63 on the two groups of support plates 62 are provided on both sides of the two connecting plates 31. When the battery assembly 3 is installed on the support plate 62, each third connecting hole 63 corresponds to a fourth connecting hole 32, and is fixed by bolts and nuts. After the bolts are passed through the third connecting hole 63 and the fourth connecting hole 32 in turn, the battery assembly 3 is fixed to the support plate 62 by nuts. The support and limit platforms 61 are fixedly arranged on the upper end surface of each group of support plates 62, and the two support and limit platforms 61 are arranged opposite to each other. The support and limit platforms 61 include a bottom plate 611 supporting the battery assembly 3 and a vertical plate 612 vertically arranged with the bottom plate 611 to limit the forward and backward movement of the battery assembly 3. The bottom plate 611 and the vertical plate 612 are fixedly connected, and preferably the bottom plate 611 and the vertical plate 612 are integrally formed. When the battery assembly 3 is installed on the support plate 62, the two sides of the bottom of the battery assembly 3 respectively abut against the support and limit platforms 61, and the support and limit platforms 61 and the support plates 62 support the battery assembly 3 at the same time, and the vertical plate 612 of the support and limit platforms 61 abuts against the front and rear sides of the battery assembly 3. When the motorcycle is bumpy or braked suddenly during riding, the battery assembly 3 can be limited from sliding forward and backward due to inertia. When the battery assembly 3 needs to be replaced or repaired, the bolt assembly at the third connecting hole 63 and the fourth connecting hole 32 is disassembled, and the battery assembly 3 can be taken out from the side.

[0036] Specifically, the bottom of one of the two support limit platforms 61 has a connecting arm 7 extending toward the motor assembly 2, and the connecting arm 7 is provided with a fifth connecting hole 71, and the motor assembly 2 is provided with a sixth connecting hole 23 corresponding to the fifth connecting hole 71. Bolts pass through the fifth connecting hole 71 and the sixth connecting hole 23 in sequence to fix the motor assembly 2 to the support limit platform 61. The connecting arm 7 and the first support arm 51 and the second support arm 52 form a triangular fixation for the motor assembly 2, further enhancing the stability of the motor assembly 2.
