Description

Technical Field

[0001] The present application relates to the technical field of electric tools, and in particular to a wall grinder. Background Art

[0002] With the continuous development of tool manufacturing technology, more and more practical tools have begun to appear, such as grinding tools, milling tools and cutting tools, which are widely used in various processing scenarios. The use of these tools not only saves manpower and greatly improves the operating efficiency of operators, but also effectively improves the processing quality of construction operations.

[0003] During construction or decoration, it is often necessary to grind the wall. Due to the low efficiency of manual operation and the huge physical exertion, a wall grinder has emerged to replace manual operation. The wall grinder is a highly practical grinding tool. Operators can operate the wall grinder to grind the wall to make the wall of the building smoother and the surface more delicate and uniform. The wall grinder mainly includes a driving mechanism, a grinding piece and a control part. When the wall grinder performs the grinding operation, the driving mechanism drives the grinding piece to operate to grind the wall. The working state of the wall grinder is controlled by the control part, and the control part can control related functions such as start and stop, operation gear, or switch of the light strip.

[0004] At present, wall grinders all use remote controllers to control the start and stop of the wall grinder and the switch of the light strip based on remote communication technology. However, due to the limited battery capacity of the remote controller itself, operators need to frequently remove the remote controller to charge or replace the battery. This affects the operator's operational convenience and may even affect the normal progress of the grinding operation due to power outages in the middle of the operation. Therefore, how to ensure the operator's operational convenience when using the wall grinder for grinding operations is an important issue. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a wall grinder, which can help ensure the operating convenience of operators when using the wall grinder for grinding operations.

[0006] In order to solve the above technical problems, the embodiment of the present application provides a wall grinder. The wall grinder includes a grinding piece, a driving mechanism, a supporting assembly, a controller, a remote control and a charging mechanism. The driving mechanism is used to drive the grinding piece. The supporting assembly is connected to the driving mechanism, and the supporting assembly includes a connecting rod and a front fork connected to one end of the connecting rod. The controller is electrically connected to the driving mechanism. The remote control and the charging mechanism are installed at the other end of the connecting rod. The remote control has a built-in rechargeable battery. The remote control has a charging mode and a battery mode. In the charging mode, the remote control is combined with the charging mechanism, and the charging mechanism charges the rechargeable battery; in the battery mode, the remote control is separated from the charging mechanism, and the remote control is used to control the controller.

[0007] The wall grinder provided in the embodiment of the present application forms a control part through two-way communication between a remote control and a controller. The remote control is a part that is easily accessible to the operator when operating the wall grinder. It is connected to the connecting rod and is located at the end of the connecting rod. The remote control can facilitate the operator to perform operation and control. In addition, the end of the connecting rod has a charging mechanism, and the remote control can be combined with the charging mechanism to obtain external power supply through the charging mechanism. When the remote control is separated from the charging mechanism, it can work through the battery configured by itself. There is no need to remove the remote control for charging or replacing the battery, thereby ensuring the convenience of operation of the operator when using the wall grinder for grinding operations.

[0008] In some embodiments, the remote controller includes a switch for driving the driving mechanism to rotate and a display screen for displaying the working status of the driving mechanism. When the switch is operated, the controller generates a control signal, the control signal controls the driving mechanism to rotate and generates a feedback signal, and the feedback signal is displayed on the display screen. In this way, the display screen on the remote controller allows the operator to more conveniently observe the operating status such as the gear position or the type of machine fault, and timely learn about the working status of the wall grinder.

[0009] In some embodiments, the charging mechanism includes a charging seat mounted on the connecting rod and a charging interface provided on the charging seat, and in the charging mode, the remote controller is coupled to the charging interface. In this way, the external power input of the remote controller can be easily realized by adopting the form of the charging interface.

[0010] In some embodiments, the charging base includes a first component and a second component mounted on the connecting rod, the first component and the second component are fixed by screws, and the charging interface is engaged between the first component and the second component.

[0011] In some embodiments, the charging interface has a first protrusion and a second protrusion extending from the end face, the first component has a first recessed portion with a recessed side wall, the second component has a second recessed portion with a recessed side wall, the first protrusion is combined with the first recessed portion, and the second protrusion is combined with the second recessed portion.

[0012] In some embodiments, in charging mode, the display screen is configured to be always on, and in battery mode, the display screen is configured to be in a dormant state after a preset time has passed. In this way, the working performance of the remote control can be ensured by controlling the working form of the remote control in different modes.

[0013] In some embodiments, the charging mechanism further includes a protective cover mounted on the charging seat, the protective cover has a first state of opening and a second state of closing, in the first state, the remote controller is in a charging mode, the remote controller is coupled to the charging interface, and in the second state, the remote controller is in a battery mode. In this way, the charging interface can be protected by providing the protective cover.

[0014] In some embodiments, the charging mechanism further comprises a rotating shaft mounted on the charging base and an elastic member sleeved on the rotating shaft, and the elastic member controls the protective cover to rotate along the rotating shaft to achieve switching between the first state and the second state. In this way, the protective cover can be automatically reset by elastic deformation of the elastic member.

[0015] In some embodiments, the connecting rod is provided with a slidable base, and the remote controller is connected to the base and can move along the axial direction of the connecting rod. In this way, the base can provide a basis for the connection of the remote controller and facilitate the position of the remote controller to be adjusted.

[0016] In some embodiments, one of the base and the remote controller is provided with a slide groove extending along the axial direction of the connecting rod, and the other is provided with a convex rib extending along the axial direction of the connecting rod, one end of the slide groove is penetrated, and when the remote controller is connected to the base, the slide groove is engaged with the convex rib. In this way, the cooperation between the convex rib and the slide groove can facilitate the operator to complete the connection between the remote controller and the base.

[0017] In some embodiments, the base is provided with a slide groove, which is arranged through one end of the slide groove near the front fork, and the width of the end of the slide groove passing through the base gradually increases in the direction close to the front fork. In this way, the remote control can be accurately and quickly slid onto the base through the opening area with varying width.

[0018] In some embodiments, the base is provided with a plurality of clamping parts, some of which are staggered and distributed on both sides of the slide slot, and at least two clamping parts are relatively arranged at the edge of the base close to the front fork. In this way, the remote control can be limited by the clamping parts and the movement process of the remote control can be guided at the same time.

[0019] The wall grinder provided in some embodiments of the present application has a charging mechanism added to the connecting rod, and the remote controller can be charged through the charging mechanism, so that the remote controller obtains external power input. The operator can realize the operation and control of the wall grinder through the cooperation between the remote controller and the controller. When the remote controller is combined with the charging mechanism, the remote controller will not consume battery power, thereby avoiding the normal operation of the wall grinder being affected by insufficient battery power of the remote controller itself, and ensuring the convenience of the operator when using the wall grinder for grinding operations.

[0037] like Figures 1 to 12As shown, the wall grinding machine provided in some embodiments of the present application includes a grinding piece 11, a driving mechanism 12, a supporting assembly 13, a controller 14, a remote controller 15 and a charging mechanism 16. The driving mechanism 12 is used to drive the grinding piece 11. The supporting assembly 13 is connected to the driving mechanism 12, and the supporting assembly 13 includes a connecting rod 131 and a front fork 132 connected to one end of the connecting rod 131. The controller 14 is electrically connected to the driving mechanism 12. The remote controller 15 and the charging mechanism 16 are installed at the other end of the connecting rod 131. A rechargeable battery is arranged in the remote controller 15. The remote controller 15 has a charging mode and a battery mode. In the charging mode, the remote controller 15 is combined with the charging mechanism 16, and the charging mechanism 16 charges the rechargeable battery; in the battery mode, the remote controller 15 is separated from the charging mechanism 16, and the remote controller 15 is used to control the controller 14.

[0038] The support assembly 13 is the part that the operator supports the wall grinder for grinding operations. The support assembly 13 can connect and fix other components, and can also provide a gripping position for the operator's operation. The connecting rod 131 part of the support assembly 13 has a certain length, which can facilitate the operator to lift the grinding piece 11 performing the grinding operation to a certain height so as to be close to the wall in front of or above the operator. The connecting rod 131 can be designed to be telescopic, that is, in the form of a double-layer sleeve, so that the operator can adjust the operating length. The connecting rod 131 can also be set to be hollow to provide a transmission channel for the dust collected at the front end. The front fork 132 is located at one end of the connecting rod 131, which is used to connect the drive mechanism 12 and the grinding head. It is the part close to the wall when the wall grinder performs grinding operations.

[0039] The driving mechanism 12 is connected to the front fork 132, and can output power under the control of the operator to drive the grinding piece 11 to operate. The driving mechanism 12 may include a motor and a transmission structure, the motor is used to generate power, and the transmission structure can transmit the movement of the motor to the grinding piece 11 in a suitable form. The grinding piece 11 is set in a disc shape, and can move under the drive of the driving mechanism 12, and grind the wall surface in the process.

[0040] The controller 14 and the remote controller 15 are the control parts of the wall grinding machine, which are used to control the start and stop of the driving mechanism 12, the gear position or the switch of the light strip around the grinding piece 11. Fig.10The power cord 141 shown receives power input and is electrically connected to the drive mechanism 12 through the first cable 142. The remote controller 15 is connected to the controller 14 in communication, sends control instructions to the controller 14, and can receive signals from the controller 14. The communication connection can be wireless communication or wired communication. The remote controller 15 is installed at the other end of the connecting rod 131, and a charging mechanism 16 is also installed at the other end of the connecting rod 131. The remote controller 15 and the charging mechanism 16 are close to the gripping position of the operator. The charging mechanism 16 can input external power to the remote controller 15 to charge the remote controller 15.

[0041] The wall grinder provided in some embodiments of the present application forms a control part through two-way communication between a remote controller 15 and a controller 14. The remote controller 15 is a part that is easily accessible to the operator when operating the wall grinder. It is connected to the connecting rod 131 and is located at the end of the connecting rod 131. The remote controller 15 can facilitate the operator to perform operation and control. In addition, the end of the connecting rod 131 has a charging mechanism 16, and the remote controller 15 can be combined with the charging mechanism 16 to obtain external power supply through the charging mechanism 16. When the remote controller 15 is separated from the charging mechanism 16, it can work through the battery configured by itself. There is no need to remove the remote controller 15 for charging or replacing the battery, thereby ensuring the convenience of operation of the operator when using the wall grinder for grinding operations.

[0042] In some embodiments, the remote controller 15 may include a switch 151 for driving the driving mechanism 12 to rotate and a display screen 152 for displaying the working state of the driving mechanism 151. By operating the switch 151, the controller 14 generates a control signal, which controls the driving mechanism 12 to rotate and generates a feedback signal, which is displayed on the display screen 152.

[0043] The operator can conveniently control the wall grinder through the switch 151 on the remote controller 15, so there is no need to perform relevant control operations on the controller 14. The switch 151 can be a button switch or a knob switch. At the same time, the remote controller 15 is provided with a display screen 152, which can display information related to the operating status of the wall grinder, such as the gear position, fault alarm type, etc., so that the operator can know the operating status of the wall grinder in time.

[0044] When the operator uses the wall grinder to grind the wall, even if the operator is far away from the controller 14, the operator can conveniently observe the operating status such as the gear position or the machine fault type through the display screen 152 provided on the remote controller 15. Thus, the operator can know the working status of the wall grinder in time.

[0045] like Figure 2As shown, the charging mechanism 16 may include a charging seat 161 mounted on the connecting rod 131 and a charging interface 162 disposed on the charging seat 161. In the charging mode, the remote controller 15 is coupled to the charging interface 162.

[0046] like Fig.11 As shown, the charging seat 161 includes a first component 1611 and a second component 1612 installed on the connecting rod 131, and the first component 1611 and the second component 1612 are fixed by screws 166, so that the charging interface 162 is clamped between the first component 1611 and the second component 1612. In addition, it should be noted that the first component 1611 and the second component 1612 are semicircular arc structures, which can better fit the outer peripheral contour of the connecting rod 131, and facilitate better installation and positioning.

[0047] Specifically, Fig.13 As shown, the charging interface 162 has a first protrusion 1621 and a second protrusion 1622 extending from the end face, the first component 1611 has a first recessed portion 161a with a recessed side wall, and the second component 1622 has a second recessed portion (not shown) with a recessed side wall. The first protrusion 1621 is combined with the first recessed portion 161a, and the second protrusion 1612 is combined with the second recessed portion, so that the charging interface 162 can be fastened to the charging seat 161, thereby improving the convenience of users in charging or disassembling the remote control 15.

[0048] The charging interface 162 is electrically connected to the controller 14, and the charging interface 162 can be connected to the remote controller 15 to charge the remote controller 15. Fig.10 That is, the second cable 143 is routed from the inside of the charging seat 161 and connected to the charging interface 162, so that the charging interface 162 has a charging function. The charging interface 162 can be installed by setting a ring on the connecting rod 131, that is, the charging seat 161. In addition, the charging interface 162 is located on the moving path of the remote control 15 when it is installed. When the remote control 15 slides to the final limit state, it can be accurately connected to the charging interface 162. Thereby realizing its own charging. By adopting the form of the charging interface 162, it is easy to realize the charging of the remote control 15 and ensure the connection stability of the remote control 15 during the charging process.

[0049] In actual situations, in the charging mode, the display screen 152 of the remote controller 15 is configured to be always on, and in the battery mode, the display screen 152 of the remote controller 15 is configured to be in a sleep state after a preset time has passed.

[0050] That is to say, the remote control 15 may include a charging mode and a battery mode; when the remote control 15 works in the charging mode, the display screen 152 is always on, and the charging interface 162 is connected to the remote control 15 to charge the remote control 15; when the remote control 15 works in the battery mode, the sleep mode is triggered after a preset time.

[0051] When the remote controller 15 is in charging mode, as long as the remote controller 15 is connected to the charging interface 162, the remote controller 15 is used in charging mode. At this time, the remote controller 15 will not sleep, and the display screen 152 is always on. The power supply of the remote controller 15 does not use the power of its own battery. At the same time, the battery of the remote controller 15 is charging in real time. For safety and battery life considerations, when the battery capacity of the remote controller 15 reaches a certain threshold, the charging stops.

[0052] When the remote controller 15 is in battery mode, the remote controller 15 is not connected to the charging interface 162. At this time, the remote controller 15 has the following states and functions: (1) the sleep mode is triggered after a preset time has passed. The preset time can be set to a suitable time, such as 5 minutes, to ensure the long battery life of the remote controller 15; (2) after the remote controller 15 is in sleep mode, any button can be pressed to wake it up; (3) when the battery of the remote controller 15 itself is exhausted or low on power, a prompt will be displayed on the display screen 152.

[0053] In actual situations, whether in charging mode or battery mode, the remote controller 15 will display other functions such as gear position and alarm type display, and increase the display brightness of the display screen 152 in a dark environment to facilitate operators to observe the displayed information.

[0054] In some embodiments, the charging mechanism 16 may further include a protective cover 163 mounted on the charging seat 161, and the protective cover 163 has a first state of opening and a second state of closing. In the first state, the remote controller 15 is in a charging mode, and the protective cover 163 is away from the charging interface 162. In the second state, the remote controller 15 is in a battery mode, and the protective cover 163 covers the charging interface 162.

[0055] like Figure 3 and Figure 4 As shown, the connecting rod 131 is provided with a rotatable protective cover 163, and the protective cover 163 can be switched between an open state and a closed state. When the protective cover 163 is in the open state, the protective cover 163 withdraws from the moving path of the remote controller 15, and exposes the charging interface 162 on the moving path of the remote controller 15. When the protective cover 163 is in the closed state, the protective cover 163 enters the moving path of the remote controller 15, and the charging interface 162 is located inside the protective cover 115.

[0056] The protective cover 163 can protect the charging interface 162. When the remote controller 15 needs to be charged, the protective cover 163 can be placed in a Figure 2 At this time, the protective cover 163 exits the moving path of the remote controller 15 and does not block the connection between the charging interface 162 and the remote controller 15. This allows the charging interface 162 and the remote controller 15 to be connected smoothly, so that the remote controller 15 enters the charging state. When the remote controller 15 does not need to be charged, the protective cover 163 can be placed in Figure 3 The protective cover 163 is in the closed state, and the charging interface 162 can be covered therein. This prevents the charging interface 162 from failing due to dust entering the wall grinder under harsh grinding conditions.

[0057] In some embodiments, the charging mechanism 16 may further include a rotating shaft 164 mounted on the charging seat 161 and an elastic member 165 sleeved on the rotating shaft 164 , and the elastic member 165 controls the protective cover 163 to rotate along the rotating shaft 164 to achieve switching between the first state and the second state.

[0058] The elastic member 165 may be a spring, a spring sheet or other elastic member. Figure 4 As shown, the elastic member 165 can be a torsion spring. The protective cover 163 is connected to the rotating shaft 164, one end of the torsion spring abuts against the connecting rod 131, and the other end of the torsion spring abuts against the protective cover 163, and the protective cover 163 is in a closed state.

[0059] The rotating shaft 164 can rotate relative to the charging seat 161 and provide a basis for the connection of the protective cover 163. The two ends of the rotating shaft 164 can pass through different parts of the protective cover 163 respectively, so as to be bound with the protective cover 163 to form a whole, so that the protective cover 163 can rotate relative to the charging seat 161. The torsion spring can realize the automatic resetting of the protective cover 163. Under the elastic force of the torsion spring, the protective cover 163 remains in a closed state, that is, a state of forming a protection for the charging interface 162. When the charging interface 162 needs to be exposed, the protective cover 163 can be pulled to compress the torsion spring. So that the charging interface 162 can be smoothly docked with the remote control 15. After the remote control 15 is docked, the protective cover 163 abuts against the remote control 15 under the elastic force of the torsion spring. When the operator moves the remote control 15 and pulls out the charging interface 162, the protective cover 163 can automatically reset to restore the closed state under the elastic force of the torsion spring. Thereby realizing the rebound function of the protective cover 163 and simplifying the operation of the operator.

[0060] When installing the protective cover 163, the rotating shaft 164 is first inserted into the inner hole at one end of the protective cover 163, and the rotating shaft 164 and the inner hole of the protective cover 163 are in interference connection. Then the torsion spring is put on the rotating shaft 164, and then one end of the rotating shaft 164 is inserted into the hole at one end of the upper end of the annular structure of the connecting rod 131 for placing the charging interface 162, and the rotating shaft 164 and the hole are in gap connection. Next, the other end of the rotating shaft 164 is inserted into the other end hole at the upper end of the annular structure of the connecting rod 131 for placing the charging interface 162. The installation process of the protective cover 163 is completed.

[0061] In some embodiments, the connecting rod 131 may be mounted with a slidable base 133 , and the remote controller 15 is connected to the base 133 and is movable along the axial direction of the connecting rod 131 .

[0062] The base 133 provides a foundation for connecting the remote controller 15 with the connecting rod 131. The base 133 has a relatively flat mounting surface, and the remote controller 15 can be mounted on the surface. At the same time, the base 133 can slide along the connecting rod 131 to Fig.13 The remote controller 15 can be adjusted to a suitable position for convenient observation and operation by the operator. The base 133 can be set to be hollow so as to be mounted on the connecting rod 131. A lock can also be designed on the base 133 to bind the base 133 to the connecting rod 131 through the lock.

[0063] The remote controller 15 and the base 133 are connected in a detachable manner. During the connection between the remote controller 15 and the base 133, the remote controller 15 is not completely locked on the base 133 and can move along the axial direction of the connecting rod 131. This allows the operator to remove the remote controller 15 when necessary. When the operator lifts the wall grinder for grinding, the remote controller 15 can be kept in a fixed position on the base 133 under the action of gravity. The display screen 152 provided on the remote controller 15 allows the operator to view the operating status information of the wall grinder. Even when the operator is performing grinding operations in a dark environment, the operator can observe information such as the gear position with the help of the brightness of the display screen 152.

[0064] In some embodiments, one of the base 133 and the remote controller 15 may be provided with a slide groove 101 extending along the axial direction of the connecting rod 131, and the other may be provided with a rib 102 extending along the axial direction of the connecting rod 131. One end of the slide groove 101 is provided through, and when the remote controller 15 is connected to the base 133, the rib 102 is inserted into the slide groove 101.

[0065] The slide groove 101 provides a guide for the remote controller 15 to be installed on the base 133. One end of the slide groove 101 is penetrated to form an opening area 1011. The rib 102 cooperates with the slide groove 101. When installing the remote controller 15, the rib 102 can be as follows. Figure 7As shown, the opening area 1011 of the slide groove 101 is inserted into the slide groove 101. Figure 8 and Fig. 9 As the remote controller 15 shown in the figure moves continuously, the length of the rib 102 inserted into the slide groove 101 gradually increases. Through the interaction between the rib 102 and the slide groove 101, it is convenient for the operator to realize the connection between the remote controller 15 and the base 133, so as to install the remote controller 15 on the connecting rod 131. In actual situations, a groove with an open end can also be provided, so that the rib 102 is first inserted into the slide groove 101 along the depth direction of the slide groove 101, and then the rib 102 is matched along the extension direction of the slide groove 101. The number of the slide groove 101 and the rib 102 can be one or more, and the cross-sectional shape of the slide groove 101 and the rib 102 can be rectangular, triangular or other shapes.

[0066] like Figure 3 and Figure 5 As shown, the base 133 may be provided with a slide groove 101 , which is arranged through one end of the slide groove 101 close to the front fork 132 , and the width of the slide groove 101 passing through one end of the base 133 gradually increases in the direction close to the front fork 132 .

[0067] That is, the slide groove 101 disposed on the base 133 forms an opening area 1011 at one end close to the front fork 132. Figure 6 The rib 102 at the bottom of the remote control 15 shown can be inserted into the slide groove 101 along the opening area 1011. By gradually increasing the width of the opening area 1011 in the direction close to the front fork 132, a funnel-shaped opening area 1011 can be formed, so that the remote control 15 can slide onto the base 133 more quickly and accurately.

[0068] In addition, the base 133 may be provided with a plurality of clamping portions 103 , and the plurality of clamping portions 103 are distributed on both sides of the slide slot 101 , and at least two clamping portions 103 are relatively arranged at the edge of the base 133 close to the front fork 132 .

[0069] The clamping portion 103 can limit the position of the remote control 15. When the rib 102 is inserted into the slide groove 101, the clamping portion 103 can prevent the position and posture of the remote control 15 from being offset. At the same time, when the rib 102 reaches the end of the slide groove 101, the clamping portion 103 can prevent the remote control 15 from easily detaching from the base 133. By providing at least two opposite clamping portions 103 at the edge of the base 133 close to the front fork 132, the installation of the remote control 15 can be better guided so that other clamping portions 103 can further limit the position of the remote control 15.

[0070] like Figure 3 and Figure 5As shown, four clamping parts 103 are arranged on the base 133. Two clamping parts 103 are distributed on each side of the slide slot 101. Two of the four clamping parts 103 are arranged relatively at the edge of the base 133 close to the front fork 132, and the other two clamping parts 103 are arranged close to the end of the slide slot 101.

[0071] Furthermore, different clamping parts 103 can be staggered in a direction perpendicular to the moving direction of the remote controller 15, so as to play a limiting role at different positions of the moving path of the remote controller 15. That is, some clamping parts 103 are staggered on both sides of the slide slot 101 and correspond to different positions of the moving path of the remote controller 15.

[0072] In this way, the remote controller 15 can be positioned by the clamping parts 103 throughout the entire moving path, and the clamping parts 103 arranged on both sides of the slide slot 101 can play a limiting role in opposite directions. By staggering some of the clamping parts 103 on both sides of the slide slot 101, the remote controller 15 can be limited, ensuring the installation effect of the remote controller 15, while reducing the number of clamping parts 103 and simplifying the structure of the base 133.

[0073] In some embodiments, each clamping portion 103 may include a first portion 1031 protruding from the surface of the base 133, and a second portion 1032 extending and bending from the protruding end of the first portion 1031, the first portion 1031 abuts against the surface of the remote control 15 close to the display screen 152, and the second portion 1032 abuts against the surface of the remote control 15 where the display screen 152 is provided.

[0074] The first part 1031 and the second part 1032 are located at different positions of the clamping part 103. The first part 1031 is the part connecting the clamping part 103 and the base 133. It protrudes from the surface of the base 113 to form a certain extension length, and can abut against the surface of the remote control 15 close to the display screen 152, that is, the side of the remote control 15 when the remote control 15 is installed. The second part 1032 is bent and extended from the protruding end of the first part 1031, and the projection of the second part 1032 on the base 113 covers the moving path of the remote control 15. The second part 1032 can abut against the front of the remote control 15 provided with the display screen 152 when the remote control 15 is installed. Therefore, through the cooperation between the first part 1031 and the second part 1032, the position of the remote control 15 is limited, so that the remote control 15 is kept fixed in the direction of the display screen 152.

[0075] In some embodiments of the present application, a display screen 152 is added to the remote controller 15 to display information such as the gear position. The gear position display is always consistent with the display content on the main controller 14, that is, two-way communication. At the same time, the remote controller 15 also supports charging at the auxiliary handle to avoid the inconvenience caused by the battery running out of power.

[0076] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present application, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present application.
