For reference, the Chinese patent with publication number CN211630958U discloses a side-mounted lawn mower, which mainly includes a gasoline engine, a fuel tank, a handle and a mowing head. The gasoline engine and the mowing head are connected through a transmission shaft, an aluminum tube is provided outside the transmission shaft, and a mowing head is provided at the front end of the transmission shaft; a shock absorber is provided between the aluminum tube and the handle; the shock absorber includes a lower base, a handle positioning block and a handle upper pressure cover, the lower base is fixed on the aluminum tube, the handle positioning block is installed on the aluminum tube, the handle positioning block is provided with a groove, the handle is installed in the groove, and the handle upper pressure cover is fixed on the handle positioning block; a shock-absorbing spring is provided between the lower base and the handle positioning block. In addition, some lawn mowers also use electric motors as power sources.

[0004] With regard to the above-mentioned related technologies, the currently commonly used gasoline engine as a power source is not environmentally friendly and is heavy; as for the electric motor as a power source, the brushed motor has a short life and both have the problem of high noise; and the brushless motor must be equipped with a controller, which requires additional space, and the heat dissipation effect of the controller and the motor itself is also relatively poor. Therefore, a lawn mower structure is urgently needed to improve the above-mentioned problems. Summary of the invention

[0005] In order to improve the above-mentioned problems caused by the power source in the lawn mower, the present application provides a side-mounted high-power electric lawn mower.

[0006] The present application provides a side-mounted high-power electric lawn mower, which adopts the following technical solution:

[0007] A side-mounted high-power electric lawn mower comprises a brushless motor, a support frame and a lawn mowing head. A transmission shaft for transmitting the brushless motor to the lawn mowing head is rotatably connected in the support frame, the support frame is connected between the brushless motor and the lawn mowing head, the brushless motor comprises a shell, a main shaft, a controller and a transmission assembly for driving the main shaft to rotate, the shell is provided with a plurality of heat dissipation grooves along the circumferential direction, the heat dissipation grooves extend along the length direction of the shell, the shell is cylindrical, the main shaft, the transmission assembly and the controller are all arranged in the shell, one end of the main shaft is fixedly connected with a fan, the fan outer cover is provided with a wind cover connected to the shell, a heat dissipation plate is fixedly connected in the shell, the heat dissipation plate divides the shell into two parts, the heat dissipation plate is located on a side of the transmission assembly away from the fan, and the heat dissipation plate is provided with a through hole through which the main shaft passes, the controller is annular and is arranged on the side of the heat dissipation plate away from the transmission assembly, a gap is left between the inner wall of the shell and the transmission assembly, the shell is provided with a wind hole connected to the gap, and the main shaft and the transmission shaft are detachably connected.

[0008] By adopting the above technical solution, the operator uses the support frame to control the mowing head, and the brushless motor drives the mowing head to rotate through the transmission shaft to achieve mowing. The brushless motor designs the controller to be installed in the shell in a ring shape, which is conducive to a more regular shape of the shell and is easy to process and install; and the heat generated by the controller is transferred to the heat sink, and the fan rotates with the main shaft to guide the filtered airflow, so that the airflow enters the shell, flows through the gap and is discharged. In the process, the heat generated by the transmission components of the motor itself and the heat of the heat sink are taken out, and the heat of the motor itself and the controller is dissipated at the same time, ensuring the heat dissipation effect.

[0009] Optionally, the MOS tube of the controller is located on a side of the controller close to the heat sink and abuts against the heat sink.

[0021] Optionally, the core is made of ferrite material.

[0022] By adopting the above technical solution, the ferrite has higher magnetic permeability and lower loss.

[0023] Optionally, the support frame includes a support rod and a joystick, both ends of the joystick are provided with handles, and the middle position of the joystick in the length direction is detachably connected to the support rod.

[0024] By adopting the above technical solution, the handle is convenient for the operator to operate the joystick, and the user can adjust the relative position of the joystick and the support rod, thereby improving the applicability.

[0025] Optionally, the head shell is provided with a wire insertion hole communicating with the inside and the outside, a switch is provided at the handle, the switch is connected to a cable, and the cable is connected to the controller via the wire insertion hole.

The brushless motor is designed to install the controller in a ring shape in the shell, which is conducive to the shape of the shell being more regular and easy to process and install; and the heat generated by the controller is transferred to the heat sink, and at the same time, the fan rotates with the main shaft to guide the filtered airflow, so that the airflow enters the shell, flows through the gap and is discharged. In the process, the heat generated by the transmission components of the motor itself and the heat of the heat sink are taken out, and the heat of the motor itself and the controller is dissipated at the same time, ensuring the heat dissipation effect;

[0029] 2. The heat generated by the MOS tube is directly transferred to the heat sink, and then the heat is efficiently taken out by the airflow passing through the heat sink;

[0030] 3. When the motor is running, the magnetic field between the stator and the rotor causes the rotor to drive the main shaft to rotate.

[0039] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0040] The embodiment of the present application discloses a side-mounted high-power electric lawn mower.

[0041] Reference Figure 1 A side-mounted high-power electric lawn mower includes a brushless motor, a support frame 8 and a mowing head 9. A transmission shaft for the brushless motor to transmit power to the mowing head 9 is rotatably connected inside the support frame 8. The support frame 8 is connected between the brushless motor and the mowing head 9. An operator uses the support frame 8 to control the mowing head 9. The brushless motor drives the mowing head 9 to rotate through the transmission shaft to achieve mowing, which is the same as the use of a conventional side-mounted lawn mower.

[0042] Reference Figure 2 and Figure 3 The brushless motor includes a housing 1, a controller 4, a main shaft 2 and a transmission assembly 3 of the main shaft 2. The controller 4 is installed in the housing 1. A fan 5 is installed at one end of the main shaft 2 located at the tail of the motor. The rotation of the main shaft 2 drives the fan 5 to rotate, guides the airflow into the housing 1, and at the same time efficiently dissipates the heat of the transmission assembly 3 and the controller 4, thereby reducing the influence of heat accumulation on the overall service life of the lawn mower.

[0043] Reference Figure 1 Specifically, the support frame 8 includes a support rod 81 and a joystick 82, which are perpendicular to each other. The support rod 81 mainly supports the mowing head 9 and the brushless motor, and the joystick 82 is mainly convenient for the operator to control. The joystick 82 is U-shaped as a whole, and the middle position in the length direction is detachably connected to the support rod 81. In this embodiment, a common rod connecting seat is selected as an example for connection. Both ends of the joystick 82 in the length direction are provided with handles for the operator to hold, thereby controlling the direction of the support frame 8 as a whole. One of the handles is installed with a switch, and a cable 42 is connected between the switch and the controller 4, so that the user can control the start and stop of the brushless motor by using the switch while holding the handle. Since the controller 4 is installed in the housing 1, the housing 1 is provided with a wire plug hole 17 that is connected inside and outside, so that the cable 42 can pass through to realize the connection between the controller 4 and the switch.

[0044] Reference Figure 1The support rod 81 is hollow, and the transmission shaft is coaxially installed in the support rod 81, and bearings and the like can be used to reduce the friction between the support rod 81. The brushless motor is located at one end of the support rod 81 in the length direction, and the end of the main shaft 2 extends outside the housing 1 and docks with the end of the transmission shaft. In this embodiment, a spline connection is preferably used, so that the transmission shaft is driven to rotate synchronously when the brushless motor is started. The other end of the transmission shaft is directly connected to the mowing head 9 to achieve transmission. In this embodiment, a common rope mowing head 9 is preferably used for illustration, and other types of common mowing heads 9 are also applicable. In addition, common structures such as a grass baffle can be installed at one end of the support rod 81 close to the mowing head 9 to enhance the functionality of the lawn mower itself, which will not be elaborated in this embodiment.

[0045] Reference Figure 2 and Figure 3 Regarding the brushless motor, the housing 1 of this embodiment is cylindrical for illustration. The housing 1 includes a head housing 11 and a tail housing 12, and the two parts are coaxially arranged and arranged along the length direction of the entire housing 1. A heat sink 14 is installed between the head housing 11 and the tail housing 12. The heat sink 14 is annular, and the outer diameter of the heat sink 14 is equivalent to the diameter of the housing 1. A plurality of bolt holes are opened at the outer edge. The head housing 11 and the tail housing 12 are fixedly connected to the heat sink 14 by bolts passing through the bolt holes. The heat sink 14 is used to separate the space inside the head housing 11 from the space inside the tail housing 12.

[0046] Reference Figure 3 and Figure 4 A through hole is provided at the center of the heat sink 14, and the main shaft 2 passes through the through hole and is coaxially installed in the housing 1. The transmission assembly 3 includes a stator 31 and a rotor 32. The stator 31 includes a support tube 311, a winding 313 and a plurality of cores 312. The aperture of the through hole is adapted to the outer diameter of the support tube 311. The support tube 311 passes through the through hole and is connected to the heat sink 14, and is relatively fixed by welding, gluing, etc., so that the heat sink 14 supports the main shaft 2. The main shaft 2 is inserted into the support tube 311, and a bearing is installed between the support tube 311 and the main shaft 2, and the support tube 311 is used to support the main shaft 2.

[0047] Reference Figure 3 and Figure 5 , a plurality of core bodies 312 are installed on the part of the support tube 311 located inside the tail housing 12. The core body 312 is annular and its outer periphery is a "T-shaped" structure that is the same as the conventional stator 31 in the art. This embodiment will not be described in detail. In this embodiment, the number of core bodies 312 is three for illustration, but the actual number is not limited and can be selected according to factors such as the required length of the stator 31. The core body 312 is arranged along the axial direction of the support tube 311 and is sleeved outside the support tube 311, and is also relatively fixed to the support tube 311 by gluing, welding, etc.

[0048] Reference Figure 5In the present embodiment, a clamping structure such as a groove and a protrusion is selectively provided between the inner wall of the core body 312 and the outer wall of the support tube 311, which plays the role of fixing the relative position of the core body 312 and the support tube 311, and at the same time can fix the relative position between different core bodies 312, so as to achieve the effects of facilitating installation and extending service life.

[0049] Reference Figure 4 The winding 313 is wound on the core 312 in the same manner as the conventional stator 31, which will not be described in detail in this embodiment. In this embodiment, the core 312 is made of ferrite, which has higher magnetic permeability and lower loss. In other embodiments, non-steel soft magnetic materials such as sendust and nanomagnetic can also be used.

[0050] Reference Figure 3 The rotor 32 is in the shape of a tube that is sleeved outside the stator 31 as a whole. The end of the rotor 32 away from the heat sink 14 is fixedly connected to a hollow plate 7. The hollow plate 7 is in the shape of a ring that is coaxially arranged with the main shaft 2, and the inner circumference is fixedly connected to the main shaft 2. The rotor 32 rotates under the magnetic force between the stator 31, thereby driving the main shaft 2 to rotate. The hollow plate 7 is located between the transmission assembly 3 and the fan 5, and the airflow introduced into the housing 1 by the fan 5 can pass through the hollow plate 7 and directly contact the transmission assembly 3.

[0051] Reference Figure 3 Since the hollow plate 7 is used to allow the airflow to directly enter between the stator 31 and the rotor 32, impurities such as dust in the airflow are likely to affect the service life of the transmission assembly 3. For slightly larger impurities, the wind shield 6 installed outside the fan 5 is used to block them in this embodiment. The wind shield 6 is bowl-shaped and fixed to the tail housing 12 at the edge of the circumference, thereby completely covering the fan 5 inside, thereby playing a protective effect on the fan 5.

[0052] Reference Figure 6 For small particles of dust, etc., the present embodiment also selectively installs a filter 16 to pre-filter the air entering the housing 1. And in the present embodiment, a columnar filter 16 is preferably installed on the outside of the wind hood 6. The cylindrical filter 16 can ensure sufficient filtering area while ensuring the air intake within the limited area of ​​the wind hood 6. The filter 16 is installed outside the wind hood 6, and the filter 16 can be disassembled, cleaned or replaced without disassembling the housing 1, and even does not affect the operation of the motor itself in a short time.

[0053] Reference Figure 3 and Figure 6Since the rotor 32 rotates at a high speed during operation, a gap is left between the rotor 32 and the inner wall of the housing 1. The airflow introduced into the housing 1 by the fan 5 not only enters between the stator 31 and the rotor 32, but also enters the gap at the same time. In addition, a plurality of heat dissipation grooves 13 are provided on the outer peripheral surface of the housing 1. The heat dissipation grooves 13 extend along the busbar direction of the housing 1. The ends of the heat dissipation grooves 13 close to the wind cover 6 are connected to the housing 1, so that the airflow at the fan 5 also flows from the outside of the housing 1 along the heat dissipation grooves 13 at the same time, thereby comprehensively reducing the heat accumulation inside and outside the motor.

[0054] Reference Figure 6 The airflow flowing from the outer shell 1 will directly contact the heat sink 14. The tail shell 12 is provided with an air hole 121 in the direction close to the heat sink 14. The airflow is discharged out of the motor from the air hole 121 along the surface of the heat sink 14. In this embodiment, the bolts at the connection between the tail shell 12 and the heat sink 14 are used to separate a gap between the tail shell 12 and the heat sink 14. The gap serves as the air hole 121, which reduces the processing difficulty of the tail shell 12.

[0055] Reference Figure 3 , the process of airflow will take away the heat of the heat sink 14. In this embodiment, the controller 4 is annularly sleeved outside the portion of the support tube 311 extending into the head shell 11, and its MOS tube 41 is located on the side close to the heat sink 14 and fits with the heat sink 14, so that the heat generated by the MOS tube 41 is quickly transferred to the heat sink 14, and then the heat is dissipated outside the motor along with the airflow passing through the heat sink 14. Among them, the material of the heat sink 14 is preferably aluminum metal with relatively strong thermal conductivity, and aluminum or aluminum alloy can be used; other types of materials with strong thermal conductivity can also be selected in other embodiments.

[0056] Reference Figure 3 and Figure 6 Since the controller 4 is installed in the head shell 11 and is separated by a heat sink 14 in the middle, the airflow will not directly contact the controller 4, avoiding the influence of static electricity, dust, etc. on the total electronic components of the controller 4, thereby ensuring the normal operation of the controller 4 and having sufficient heat dissipation capacity.

[0057] Reference Figure 6 and Figure 7 A baffle ring 15 is selectively provided on the outside of the housing 1. The baffle ring 15 is sleeved on the outside of the housing 1. When the motor is in normal operation, the baffle ring 15 is directly above the air hole 121. The airflow blown out of the air hole 121 is deflected by the baffle ring 15, and then flows through the surface of the housing 1 along the heat dissipation groove 13 to dissipate the heat generated in various parts of the motor.

[0058] The implementation principle of a side-mounted high-power electric lawn mower in the embodiment of the present application is as follows: the operator uses the support frame 8 to control the mowing head 9, and the brushless motor drives the mowing head 9 to rotate through the transmission shaft to achieve mowing, which is the same as the use of a conventional side-mounted lawn mower. The brushless motor designs the controller 4 to be installed in the housing 1 in a ring shape, which is conducive to a more regular shape of the housing 1, and is easy to process and install; and the heat generated by the controller 4 is conducted to the heat sink 14, and at the same time, the fan 5 rotates with the main shaft 2 to guide the filtered airflow, so that the airflow enters the housing 1, flows through the gap and is discharged, and in the process, the heat generated by the transmission component 3 of the motor itself and the heat of the heat sink 14 are taken out, and at the same time, the heat of the motor itself and the controller 4 is dissipated to ensure the heat dissipation effect.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
