[0002] This application claims priority to Chinese patent application No. 202510238124.1, filed with the Chinese Patent Office on February 28, 2025, entitled "Electric Motorcycle". Technical Field

[0003] This application relates to the field of vehicle technology, and more particularly to an electric motorcycle. Background Technology

[0004] Against the backdrop of increasingly severe environmental pollution and energy shortages, and the gradual replacement of gasoline and diesel as the driving energy source for vehicles due to the advantages of energy saving and environmental protection, the use of electric energy as a driving energy source is also gradually extending from road-use electric motorcycles to electric motorcycles in various functional scenarios. Unlike road-use electric motorcycles, off-road electric motorcycles require frequent extreme acceleration, resulting in more serious energy consumption and exhaust pollution. In order to further achieve energy saving and environmental protection, it is particularly important to reform off-road electric motorcycles into electric motorcycles.

[0005] The power battery, motor control components in the electronic control system, and the motor itself are the core components of an electric motorcycle, and their arrangement and placement affect the motorcycle's off-road performance. Existing electric motorcycles suffer from the following problems:

[0006] The connection stability between the power battery and the vehicle frame is not high enough, especially during off-road driving. Utility Model Content

[0007] In view of this, it is necessary to provide an electric motorcycle with a high degree of stability in the connection between the power battery and the frame.

[0008] Embodiments of this application provide an electric motorcycle, including a frame, a body panel, and a power battery. The body panel at least partially covers the frame. The power battery is supported by the frame. The frame includes an upper crossbeam and a lower crossbeam, forming a receiving space between the upper and lower crossbeams. The power battery is mounted in the receiving space. A mounting assembly is connected to the frame, the mounting assembly including an upper mounting cover and a lower mounting cover. The upper mounting cover is connected to the upper crossbeam, and the lower mounting cover is connected to the lower crossbeam. The upper mounting cover covers the top of the power battery from top to bottom, and the lower mounting cover covers the bottom of the power battery from bottom to top. The upper and lower mounting covers can jointly restrict the movement of the power battery along the arrangement direction of the upper and lower mounting covers, and restrict the movement of the power battery in a direction perpendicular to the arrangement direction of the upper and lower mounting covers.

[0009] Furthermore, the lower mounting cover includes a first bracket, a second bracket, and a baffle. The first bracket, the power battery, and the second bracket are arranged sequentially from front to back. The first bracket is used to limit the front side of the power battery and to limit one side of the left or right side of the power battery. The second bracket is used to limit the rear side of the power battery. The baffle is detachably connected to the first bracket and / or the second bracket and is used to limit the other side of the left or right side of the power battery.

[0010] Furthermore, the first bracket has a snap-fit ​​groove on the side near the baffle, which snaps into the baffle, and the second bracket is connected to the baffle on the side near the baffle by bolts.

[0011] Furthermore, the upper mounting cover includes an upper fixing plate and a side fixing plate connected to the periphery of the upper fixing plate. The upper fixing plate is connected to the upper crossbeam, and the side fixing plate extends downward from the edge of the upper fixing plate. The upper fixing plate is in contact with the upper end face of the power battery, and the side fixing plate is used to limit the periphery of the power battery. The upper fixing plate and the side fixing plate are integrally formed structures.

[0012] Furthermore, the upper mounting cover is connected to multiple upper buffer components, which are sponge pads; the upper fixing plate is provided with at least one upper buffer component on the side near the power battery, and the side fixing plate is provided with at least one upper buffer component on the side near the power battery.

[0013] Furthermore, the power battery has a centerline, which is basically parallel to the long side of the power battery. The length direction of the side fixing plate is basically perpendicular to the centerline direction of the power battery. The side fixing plate includes a first fixing area and two second fixing areas located on both sides of the first fixing area along the length direction of the side fixing plate. The width of the first fixing area is greater than the width of the second fixing area. The upper buffer is located in the first fixing area.

[0014] Furthermore, the electric motorcycle also includes an electronic control system installed in the housing space. The electronic control system includes a control wiring harness; multiple wiring harness fasteners are connected to the upper mounting cover, and wiring harness fasteners are connected to the second fixing area of ​​the side fixing plate on at least one of the left and right sides of the power battery.

[0015] Furthermore, the top of the power battery is equipped with a plug connector; the upper fixing plate is equipped with a rear hole, through which the plug connector passes from top to bottom and is plugged into the power battery.

[0016] Furthermore, a fastener is connected to the upper mounting cover. The fastener includes a first fixing part, multiple claws, and a second fixing part. The first fixing part is attached to the upper surface of the upper fixing plate. The claws are fixed to the first fixing part and abut against the side wall of the upper fixing plate. The claws are used to limit the relative displacement of the first fixing part and the upper fixing plate in the front-rear and left-right directions of the frame. The end of the second fixing part away from the first fixing part extends upward to form an extension end. The fastener is connected to the frame through the extension end.

[0017] Furthermore, the electric motorcycle also includes an electronic control system, which includes a motor control component mounted on a mounting cover and / or a lower mounting cover; the motor control component includes a motor controller and a radiator, the radiator being connected to the front or rear side of the motor controller, and at least one of the radiator and the motor controller being fixed to the upper mounting cover and / or the lower mounting cover.

[0018] In this application, by covering the upper and lower ends of the power battery with an upper mounting cover and a lower mounting cover respectively, the upper and lower mounting covers can limit the power battery in multiple directions. The multiple directions include the arrangement direction of the upper and lower mounting covers, that is, the long side direction of the power battery when viewed from the left and right direction. The multiple directions also include the direction perpendicular to the arrangement direction of the upper and lower mounting covers. Ultimately, the power battery can be stably connected to the vehicle frame through the upper and lower mounting covers. Attached Figure Description

[0028] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] When a component is considered to be "located" on another component, it can be directly on the other component or may also be interspersed with other components. When a component is considered to be "connected" to another component, it can be directly connected to the other component or may also be interspersed with other components.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] It is understandable that the term "perpendicular" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately perpendicular or equal to each other. For example, combined with numerical description, perpendicularity can refer to the angle between two straight lines within the range of 90° ± 10°, the dihedral angle between two planes within the range of 90° ± 10°, or the angle between a straight line and a plane within the range of 90° ± 10°. The two components described as "perpendicular" do not have to be absolutely straight lines or planes; they can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is a straight line or plane, the component can be considered a "straight line" or "plane".

[0032] The term "parallel" is used to describe an ideal state between two components. In actual production or use, two components can exist in a state that is approximately parallel. For example, in numerical terms, parallel can refer to the angle between two straight lines within the range of 180° ± 10°, the dihedral angle between two planes within the range of 180° ± 10°, or the angle between a straight line and a plane within the range of 180° ± 10°. The two components described as "parallel" do not have to be absolutely straight lines or planes; they can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is straight or plane, the component can be considered a "straight line" or "plane".

[0033] Unless otherwise defined, the term "multiple" in this document, when used to describe the number of components, specifically means that the component is two or more.

[0034] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0035] Please refer to the following: Figure 1 and Figure 2 The electric motorcycle 100 includes a frame 11, a body panel 12, a motor 200, a power battery 13, an electronic control system (not shown), a running system 15, and a suspension system 16. The frame 11 forms the basic framework of the electric motorcycle 100 and supports other components. The body panel 12 is at least partially mounted on the frame 11 and protects the internal parts of the electric motorcycle 100. The power battery 13 supplies power to the motor 200. The electronic control system includes a motor control component 14 electrically connected to the motor 200 and primarily controls the motor 200. The motor control component 14 may include a motor controller 141. The running system 15 is connected to the motor 200 and receives driving force from the motor 200 to propel the electric motorcycle 100. The running system 15 includes a front running wheel 151 located at the front of the electric motorcycle 100 and a rear running wheel 152 located at the rear of the electric motorcycle 100, with the front running wheel 151 and the rear running wheel 152 respectively rotatably connected to the front and rear ends of the frame 11. The suspension system 16 includes a front suspension assembly 161 and a rear suspension assembly 162, with the front suspension assembly 161 connecting the front running wheel 151 to the frame 11 and the rear suspension assembly 162 connecting the rear running wheel 152 to the frame 11.

[0036] For ease of expression, the definitions in this application are as follows: Figure 3 The directions shown are front, back, left, right, up, and down. The front-back direction refers to the length of the frame 11 of the electric motorcycle 100, the left-right direction refers to the width of the frame 11, and the up-down direction refers to the height of the frame 11. In this embodiment, the front, back, left, right, up, and down directions are based on the electric motorcycle 100 traveling on a level road surface, not on a sloping road surface.

[0037] Please see Figure 2In one implementation, the frame 11 includes an upper crossbeam 111 and a lower crossbeam 112. Both the upper crossbeam 111 and the lower crossbeam 112 can be optionally composed of support tubes distributed on the left and right sides of the electric motorcycle 100. A horizontal tube is also provided between the left and right support tubes to achieve a fixed connection between the left and right support tubes. Observing the frame 11 in the left-right direction, a receiving space 101 is formed between the upper crossbeam 111 and the lower crossbeam 112. The power battery 13 is installed in the receiving space 101. The power battery 13 includes an upper end face 131 and a lower end face 132. The upper end face 131 is connected to the upper crossbeam 111, and the lower end face 132 is connected to the lower crossbeam 112.

[0038] The motor control assembly 14 also includes a heat sink 142 and a control wiring harness 143 connecting the motor controller 141 and the motor 200. The heat sink 142 is connected to the front or rear of the motor controller 141 and has heat dissipation fins. The heat sink 142 is used to dissipate heat from the motor controller 141. In one implementation, the heat sink 142 is connected to the rear of the motor controller 141, that is, the heat sink 142 is located between the motor controller 141 and the power battery 13. In this case, the front of the heat sink 142 is blocked by the motor controller 141, and the heat dissipation effect is limited. However, since the front of the motor controller 141 is unobstructed, there is enough space on its front to accommodate the power connector connected to the motor controller 141. In other words, this arrangement facilitates the placement of the power connector. In another implementation, the radiator 142 is connected to the front of the motor controller 141, that is, the radiator 142 is located on the side of the motor controller 141 away from the power battery 13. In this case, the front side of the radiator 142 is the windward side and can be unobstructed by the motor controller 141, so that the airflow on the front side can be used for heat dissipation.

[0039] The radiator 142 is connected to the power battery 13. This configuration supports the motor control component 14, thereby improving the stability of the motor control component 14 in the housing space 101.

[0040] Please see Figure 4 and Figure 5 The vehicle body panel 12 includes a seat cushion 121, which is disposed on top of the frame 11 for the driver to sit on. The seat cushion 121 includes a seat cushion body 1211 and a first upper connector 1212A connected to the lower part of the seat cushion body 1211. The frame 11 includes a first lower connector 1191, and the first upper connector 1212A is correspondingly connected to the first lower connector 1191 to improve the stability of the connection between the seat cushion 121 and the frame 11 and to facilitate the removal of the seat cushion 121.

[0041] The first upper connector 1212A has a latch 1212D and abutments 1212E arranged on both sides of the latch 1212D in the left-right direction. The front side of the latch 1212D has an opening. The first lower connector 1191 has a front sheet metal 1191A and a latch 1191B fixed to the front sheet metal 1191A. The thickness direction of the front sheet metal 1191A is basically perpendicular to the extension direction of the upper crossbeam 111. The end of the latch 1191B away from the front sheet metal 1191A is bent backward and upward relative to the front sheet metal 1191A. The latch 1191B extends into the opening on the front side of the latch 1212D and engages with the latch 1212D. The abutments 1212E abut downward against the front sheet metal 1191A to stably fix the front end of the seat cushion 121 to the frame 11. In one specific implementation, the abutment 1212E is a rubber pad to increase the friction between the abutment 1212E and the front sheet metal 1191A, so that the front sheet metal 1191A can better support the abutment 1212E.

[0042] The first lower connector 1191 also has a connecting portion 1191C fixed to the front sheet metal 1191A. The connecting portion 1191C is bent backward and downward relative to the front sheet metal 1191A. The connecting portion 1191C is snapped into and / or bolted to the power battery 13 to improve the stability of the connection between the power battery 13 and the frame 11. In one specific implementation, the end of the connecting portion 1191C away from the front sheet metal 1191A is bent backward and downward relative to the front sheet metal 1191A.

[0043] Please see Figure 6 A mounting assembly 19 is connected to the frame 11. The mounting assembly 19 includes an upper mounting cover 191 and a lower mounting cover 192. The upper mounting cover 191 is connected to the upper crossbeam 111, and the lower mounting cover 192 is connected to the lower crossbeam 112. The upper mounting cover 191 covers the top of the power battery 13 from top to bottom, and the lower mounting cover 192 covers the bottom of the power battery 13 from bottom to top. The upper mounting cover 191 and the lower mounting cover 192 cooperate to limit the movement of the power battery 13. The upper mounting cover 191 and the lower mounting cover 192 can jointly limit the movement of the power battery 13 along the arrangement direction of the upper mounting cover 191 and the lower mounting cover 192, and limit the movement of the power battery 13 in a direction perpendicular to the arrangement direction of the upper mounting cover 191 and the lower mounting cover 192. The arrangement direction of the upper mounting cover 191 and the lower mounting cover 192 is the direction in which the long side of the power battery 13 extends when viewed from the left and right. The direction perpendicular to the arrangement direction of the upper mounting cover 191 and the lower mounting cover 192 includes at least two non-parallel directions, such as one direction being parallel to the left and right direction of the frame 11, and the other direction being the direction in which the short side of the power battery 13 extends when viewed from the left and right.

[0044] There are multiple contact areas between the upper mounting cover 191 and the power battery 13. These contact areas can be discontinuous or continuous. If they are continuous, the combined contact areas form a ring around the outer perimeter of the power battery 13. Similarly, there are multiple discontinuous contact areas between the lower mounting cover 192 and the power battery 13. These contact areas can also be discontinuous or continuous, and if they are continuous, the combined contact areas form a ring around the outer perimeter of the power battery 13. Furthermore, the power battery 13 has at least one relatively large contact area with both the upper and lower mounting covers 191 and 192. This design stabilizes and limits the power battery 13 while mitigating stress concentration, improving its safety and consequently enhancing the safety performance of the electric motorcycle 100.

[0045] Please see Figure 7 The lower mounting cover 192 includes a first bracket 1921, a second bracket 1922, and a baffle 1923. The first bracket 1921, the power battery 13, and the second bracket 1922 are arranged sequentially from front to back along the extension direction of the lower crossbeam 112. The first bracket 1921 is used to limit the front side of the power battery 13 and to limit one of the left and right sides of the power battery 13, optionally the left side. The second bracket 1922 is used to limit the rear side of the power battery 13. The baffle 1923 is detachably connected to the right side of the first bracket 1921 and / or the second bracket 1922, and the baffle 1923 is used to limit the other side of the left and right sides of the power battery 13, optionally the right side. This configuration, firstly, facilitates the welding of the first bracket 1921 and the second bracket 1922 to the lower crossbeam 112, thereby improving the stability of the connection between the lower mounting cover 192 and the lower crossbeam 112. Secondly, the detachable baffle 1923 facilitates the installation and removal of the power battery 13.

[0046] The first bracket 1921 includes a first limiting plate 1921A, a second limiting plate 1921B, and a third limiting plate 1921C. The first limiting plate 1921A is connected to the front end of the lower crossbeam 112 and supports the lower end face 132 of the power battery 13. The second limiting plate 1921B is connected to the front side of the first limiting plate 1921A. The second limiting plate 1921B and the power battery 13 are arranged sequentially from front to back along the extension direction of the lower crossbeam 112. The second limiting plate 1921B is used to limit the front side of the power battery 13. The third limiting plate 1921C is connected to the left side of the second limiting plate 1921B. The third limiting plate 1921C and the power battery 13 are arranged sequentially from left to right. The third limiting plate 1921C is used to limit the power battery 13 on the left side.

[0047] The right side of the first limiting plate 1921A is provided with a snap-fit ​​groove 1921D, which snaps into the baffle 1923 to improve the stability of the connection between the baffle 1923 and the first bracket 1921 and to facilitate the disassembly of the baffle 1923.

[0048] The first bracket 1921 also includes multiple front buffers 1921E. At least one front buffer 1921E is provided on the side of the first limiting plate 1921A near the power battery 13; at least one front buffer 1921E is provided on the side of the second limiting plate 1921B near the power battery 13; and at least one front buffer 1921E is provided on the side of the third limiting plate 1921C near the power battery 13. The front buffers 1921E are used to buffer the power battery 13, reducing the risk of damage caused by concentrated local forces on the power battery 13 and improving the safety performance of the electric motorcycle 100. In one specific implementation, the front buffer 1921E is a rubber pad.

[0049] The first bracket 1921 also includes a lower connecting plate 1921F. One end of the lower connecting plate 1921F is connected to the second limiting plate 1921B. The end of the lower connecting plate 1921F away from the second limiting plate 1921B is connected to the radiator 142 by bolts to support the motor control assembly 14, thereby improving the stability of the motor control assembly 14 in the accommodating space 101.

[0050] The second bracket 1922 includes a first support plate 1922A and a second support plate 1922B. The first support plate 1922A is connected to the rear end of the lower crossbeam 112 and supports the lower end face 132 of the power battery 13. The second support plate 1922B is connected to the rear side of the first support plate 1922A. The power battery 13 and the second support plate 1922B are arranged sequentially from front to back along the extension direction of the lower crossbeam 112. The second support plate 1922B is used to limit the rear side of the power battery 13. The right side of the second bracket 1922 is bolted to the baffle 1923 to improve the stability of the connection between the baffle 1923 and the second bracket 1922 and to facilitate the disassembly of the baffle 1923.

[0051] In one specific implementation, the second support 1922 includes a third support plate 1922C, which is connected to the right side of the second support plate 1922B and extends away from the first support 1921. The third support plate 1922C is used to be bolted to the baffle 1923.

[0052] The second bracket 1922 also includes multiple rear buffers 1922D. Two rear buffers 1922D are located on the side of the first support plate 1922A near the power battery 13, and two rear buffers 1922D are located on the side of the second support plate 1922B near the power battery 13. The rear buffers 1922D are used to cushion the power battery 13, reducing the risk of damage due to concentrated localized force on the power battery 13 and improving the safety performance of the electric motorcycle 100. In one specific implementation, the rear buffers 1922D are rubber pads.

[0053] A right buffer 1923A is provided on the side of the baffle 1923 closest to the power battery 13. The right buffer 1923A is used to buffer the right side of the power battery 13 to reduce the risk of damage caused by concentrated local force on the power battery 13, thereby improving the safety performance of the electric motorcycle 100. In one specific implementation, the right buffer 1923A is a sponge pad. Compared with a rubber pad, the sponge pad has a larger contact surface, which can disperse stress during the assembly and disassembly of the baffle 1923, making it easier to assemble and disassemble the baffle 1923.

[0054] Please see Figure 8 The upper mounting cover 191 includes an upper fixing plate 1911 and side fixing plates 1912 connected to the upper fixing plate 1911. The upper fixing plate 1911 is connected to the upper crossbeam 111, and the side fixing plates 1912 extend from the edge of the upper fixing plate 1911 in a direction away from the upper crossbeam 111. The upper fixing plate 1911 is in contact with the upper end face 131 of the power battery 13, and the side fixing plates 1912 are used to limit the periphery of the power battery 13. In one specific implementation, there are four side fixing plates 1912, of which two side fixing plates 1912 are arranged at intervals along the extension direction of the upper crossbeam 111, and the other two side fixing plates 1912 are arranged at intervals from left to right.

[0055] The upper fixing plate 1911 and the four side fixing plates 1912 are integrally formed structures. The side fixing plates 1912 are formed by bending process, which gives the upper mounting cover 191 good integrity and strength.

[0056] Multiple upper buffers 1913 are connected to the upper mounting cover 191. At least one upper buffer 1913 is provided on the side of the upper fixing plate 1911 closest to the power battery 13, and at least one upper buffer 1913 is provided on the side of each side fixing plate 1912 closest to the power battery 13. The upper buffers 1913 are used to buffer the power battery 13, reducing the risk of damage caused by concentrated local forces on the power battery 13 and improving the safety performance of the electric motorcycle 100. In one specific implementation, the upper buffer 1913 is a sponge pad. The buffers of the lower mounting cover 192 only need to provide support; excessive softness would affect the stability of the support, so rubber pads are often used as buffers. The upper buffer 1913 mainly serves to limit and dampen vibrations. In the case of vertical vibration of the power battery 13, using a rubber pad for the upper buffer 1913 would result in poor vibration resistance, increasing the risk of damage to the power battery 13. Using a sponge pad for the upper buffer 1913 can reduce this risk.

[0057] The side fixing plate 1912 is substantially perpendicular to the centerline 102 of the power battery 13 in its length direction, and substantially parallel to the centerline 102 of the power battery 13 in its width direction. The centerline 102 of the power battery 13 is substantially parallel to its long side, and the direction of the centerline 102 refers to the direction of inclination of the power battery 13. The side fixing plate 1912 includes a first fixing area 1912A and second fixing areas 1912B located on both sides of the first fixing area 1912A along its length direction. The width of the first fixing area 1912A is greater than the width of the second fixing area 1912B, and the width direction of the side fixing plate 1912 is substantially parallel to the extension direction of the centerline 102 of the power battery 13. An upper buffer member 1913 is disposed in the first fixing area 1912A. This arrangement allows for a wider upper buffer member 1913 within the wider first fixing area 1912A, increasing the buffer area.

[0058] The power battery 13 has a power connector 133 on its top, which is located on the upper end face 131. The power connector 133 is electrically connected to the motor control assembly 14 via a wiring harness. The upper fixing plate 1911 has a rear hole 1911A, through which the power connector 133 passes and is connected to the power battery 13.

[0059] A fastener 1914 is connected to the upper mounting cover 191. The fastener 1914 is connected to the upper fixing plate 1911 and the first lower connector 1191. The first lower connector 1191 can serve as both the mounting base for the seat cushion 121 and the mounting base for the upper mounting cover 191, which helps to make the upper mounting cover 191 and the seat cushion 121 compactly arranged on the frame 11.

[0060] Please refer to the following: Figure 8 and Figure 9 The fixing member 1914 includes a first fixing part 1914A, multiple claws 1914B, and two second fixing parts 1914C. The first fixing part 1914A overlaps, fits, and connects with the upper fixing plate 1911 in the vertical direction. The claws 1914B are fixed to the first fixing part 1914A and abut against the side wall of the upper fixing plate 1911. Specifically, the claws 1914B are integrally formed with the first fixing part 1914A. There are three claws 1914B, one of which is located on the front side of the first fixing part 1914A, and the other two are located on the rear side of the first fixing part 1914A, thereby restricting the relative displacement between the fixing member 1914 and the first fixing part 1914A in the front-rear direction. The upper fixing plate 1911 has a front hole 1911B located in front of the rear hole 1911A, and the front group of claws 1914B abuts against the rear edge of the front hole 1911B. The two rear retaining claws 1914B are arranged in the left-right direction. The rear retaining claws 1914B not only abut against the front edge of the rear hole 1911A, but also against the left and right edges of the rear hole 1911A, thus limiting the relative displacement between the fixing member 1914 and the first fixing part 1914A in the left-right direction. The front hole 1911B and the rear hole 1911A facilitate the abutment of the retaining claws 1914B against the first fixing part 1914A, and also serve as heat dissipation holes for the upper mounting cover 191 to facilitate heat dissipation from the head of the power battery 13. The two second fixing parts 1914C are arranged in the left-right direction. The end of the second fixing part 1914C away from the upper fixing plate 1911 extends upward to form an extension end 1914D. The extension end 1914D connects to the first lower connecting member 1191 (see...). Figure 4 The connecting parts 1191C overlap in the vertical direction and are connected by bolts.

[0061] Multiple wiring harness fasteners 1915 are connected to the upper mounting cover 191. These fasteners 1915 are connected to side mounting plates 1912 located on the left and / or right sides of the power battery 13, and are arranged along the length of the side mounting plates 1912 in the second fixing area 1912B. Control wiring harness 143 passes through the multiple wiring harness fasteners 1915, which are used to position the control wiring harness 143. In one specific implementation, the wiring harness fasteners 1915 are cable ties.

[0062] An upper connecting plate 1916 is connected to the upper mounting cover 191. One end of the upper connecting plate 1916 is connected to the side fixing plate 1912 near the motor control assembly 14. The other end of the upper connecting plate 1916 away from the side fixing plate 1912 is connected to the heat sink 142 by bolts to support the motor control assembly 14 and thereby improve the stability of the motor control assembly 14 in the accommodating space 101.

[0063] Those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the spirit and essence of this application fall within the scope of this application's disclosure.
