[0033] Currently, mobile devices like lawn mowers typically have multiple body structures to facilitate production and transportation. Each body structure typically requires the assembly of numerous electrical components, such as control units, batteries, sensors, drive motors, and operating equipment. Because these numerous electrical components must be connected to the control elements via cables, and their distribution spans across the vehicle, the cabling layout is complex, requiring significant time and effort to install and wire these components.

[0034] To this end, the present application provides a vehicle body device and a lawn mower, which has the effect of simplifying the cable layout of the entire lawn mower vehicle, can save the installation time of the lawn mower, and improve production efficiency.

[0035] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0036] See also Figure 1 The vehicle body equipment provided in the embodiment of the present application includes a vehicle body 10, an electrical connection structure, and multiple electrical devices. The electrical connection structure and the electrical devices are both mounted on the vehicle body 10, and the multiple electrical devices are electrically connected via the electrical connection structure. The vehicle body equipment provided in the embodiment of the present application can be applied to mobile working equipment, such as a lawn mower. The embodiment of the present application is described using a lawn mower as an example. The lawn mower can be a lawn mower robot, a push lawn mower, or a riding lawn mower.

[0037] See also Figure 2 Specifically, the vehicle body 10 has a first section 11 and a second section 12, and there is a distance between the first section 11 and the second section 12, that is, the first section 11 and the second section 12 are respectively located at different positions on the vehicle body 10. The first section 11 and the second section 12 can each be equipped with multiple electrical devices.

[0038] The electrical device includes a first electrical component 50 installed at the first section 11 and a second electrical component 60 installed at the second section 12 .

[0039] See also Figure 2 and Figure 3The electrical connection structure includes a first collecting plate 20, a second collecting plate 30 and a flexible circuit board 40. The first collecting plate 20 and the second collecting plate 30 are both electrically connected to the flexible circuit board 40. The first collecting plate 20 and the second collecting plate 30 are respectively arranged at different positions on the flexible circuit board 40.

[0040] Specifically, the first collecting plate 20 is disposed at one end of the flexible circuit board 40 near the first section 11, and the second collecting plate 30 is disposed at one end of the flexible circuit board 40 near the second section 12. The first collecting plate 20 is electrically connected to the first electrical component 50 via a cable, and the second collecting plate 30 is electrically connected to the second electrical component 60 via a cable. The first collecting plate 20 corresponds to the first section 11, and the second collecting plate 30 corresponds to the second section 12.

[0041] It is understood that the first section 11 and the second section 12 can actually be used to divide electrical devices at different locations into zones, that is, to define a first electrical device 50 and a second electrical device 60. By electrically connecting the first electrical device 50 with the first collecting plate 20, the cables of the various electrical devices on the first section 11 can be collected. Furthermore, the first electrical device 50 does not need to connect to the second collecting plate 30 across the distance between the first section 11 and the second section 12; the first electrical device 50 can simply connect directly to the nearby first collecting plate 20.

[0042] Similarly, by using the second collecting plate 30 to electrically connect the second electrical device 60, the cables of various electrical devices on the second section 12 can be collected, and the second electrical device 60 does not need to cross the distance between the first section 11 and the second section 12 to connect to the first collecting plate 20. The second electrical device 60 can be directly connected to the nearby second collecting plate 30.

[0043] It can be understood that the first collecting plate 20 and the second collecting plate 30 can collect cables within a specified range at different positions according to the principle of proximity, thereby realizing distributed management of the cables of the entire vehicle and simplifying the cable layout of the entire vehicle.

[0044] The first collecting plate 20 and the second collecting plate 30 are electrically connected via the flexible circuit board 40. The flexible circuit board 40 can provide a larger wiring range so that electrical devices at different positions on the vehicle body 10 can be connected to corresponding collecting plates.

[0045] On the other hand, the flexible circuit board 40 can organize the cables of the first collecting board 20 and the second collecting board 30, thereby simplifying the cable distribution between the first collecting board 20 and the second collecting board 30, making the wire layout simpler and the wiring installation more convenient.

[0046] It should be understood that the first and second sections 11 and 12 of this application are examples of locations where multiple electrical devices may be installed on the vehicle body 10, and are not intended to limit the specific locations where these electrical devices may be installed. In some embodiments, the specific location of the first section 11 or the second section 12 may be determined based on locations on the vehicle body 10 with a high density of electrical devices or cables, or based on factors such as the length and width of the vehicle body 10, and this application does not impose any limitations on these locations.

[0047] In one embodiment of this invention, the first section 11 and the second section 12 are arranged front to back as an example. Specifically, the first section 11 is the front end of the vehicle body 10, that is, the end of the vehicle body 10 facing forward when moving. The second section 12 is the rear end of the vehicle body 10, that is, the end of the vehicle body 10 facing backward when moving.

[0048] In other embodiments, the first section 11 and the second section 12 may also be distributed left and right, or the first section 11 and the second section 12 may also be arranged according to the shape of the vehicle body 10, which is not limited in this application.

[0049] See also Figure 2 and Figure 3 In one embodiment of the present application, the first collecting plate 20 is provided with a first electrical interface 21, and the connection terminal of the first electrical device 50 is provided with a connector adapted to the first electrical interface 21, and the connection terminal of the first electrical device 50 can be connected to the first electrical interface 21 in a plug-in manner through the connector.

[0050] When assembling the cable of the first electrical device 50 , the plug of the terminal can be directly plugged into the first electrical interface 21 after the terminal is arranged to achieve electrical connection, thereby improving the cable assembly efficiency.

[0051] On the other hand, the plug-in connection provided by the first electrical interface 21 can facilitate the disassembly of the terminal of the first electrical device 50, which is convenient for subsequent equipment maintenance or hardware replacement.

[0052] It is understandable that the first electrical components 50 can also be provided with connectors according to the actual hardware type, that is, a portion of the first electrical components 50 can be connected to the first collecting plate 20 via the first electrical interface 21, and another portion of the first electrical components 50 can be connected to the first collecting plate 20 by welding.

[0053] In one embodiment of the present application, the second collecting plate 30 is provided with a second electrical interface 31, and the connection terminal of the second electrical device 60 is provided with a connector adapted to the second electrical interface 31, and the connection terminal of the second electrical device 60 can be plugged in and connected to the second electrical interface 31 through the connector.

[0054] When assembling the cable of the second electrical device 60 , the plug of the terminal can be directly plugged into the second electrical interface 31 after the terminal is arranged to achieve electrical connection, thereby improving the cable assembly efficiency.

[0055] On the other hand, the plug-in connection provided by the second electrical interface 31 can facilitate the disassembly of the connection terminal of the second electrical device 60, which is convenient for subsequent equipment maintenance or hardware replacement.

[0056] It is understandable that the second electrical device 60 can also be provided with connectors according to the actual hardware type, that is, a portion of the second electrical device 60 can be connected to the second collecting board through the second electrical interface 31, and another portion of the second electrical device 60 can be connected to the second collecting board 30 by welding.

[0057] See also Figure 2 and Figure 3 In one embodiment of the present application, the first section 11 and the second section 12 are respectively located at the front and rear ends of the vehicle body 10 , that is, the distribution direction between the first section 11 and the second section 12 is the length direction of the vehicle body 10 .

[0058] The flexible circuit board 40 is laid and fixed along the length direction of the vehicle body 10 , and the first collecting plate 20 and the second collecting plate 30 are distributed along the length direction of the flexible circuit board 40 , so that the laying direction of the flexible circuit board 40 corresponds to the distribution direction between the first section 11 and the second section 12 .

[0059] After the flexible circuit board 40 is conveniently laid out according to the length of the vehicle body 10 , the first collecting plate 20 can be located at the position corresponding to the first section 11 , and the second collecting plate 30 can be located at the position corresponding to the second section 12 , which is convenient for installation.

[0060] In one embodiment of the present application, the flexible circuit board 40 is fixed to the vehicle body 10 by bonding, and the first collecting plate 20 and the second collecting plate 30 are also fixed to the vehicle body 10 by bonding. The bonding material may be adhesive.

[0061] In some feasible embodiments, the flexible circuit board 40 may also be fixed to the vehicle body 10 in a detachable manner, such as bolting, snapping, or clamping, to facilitate the removal of the flexible circuit board 40 for later maintenance.

[0062] See also Figure 2 and Figure 3 In one embodiment of the present application, the first and second collecting plates 20 and 30 are both soldered to corresponding locations on the flexible printed circuit board 40. The first, second, and flexible printed circuit boards 40 form an integral structure. When securing the flexible printed circuit board 40, the first, second, and flexible printed circuit boards 40 can be directly mounted and fixed to the vehicle body 10 as a single unit.

[0063] In some feasible embodiments, the first collecting plate 20, the second collecting plate 30, and the flexible circuit board 40 may also adopt a separate structure. For example, the first collecting plate 20 and the second collecting plate 30 are connected to the flexible circuit board 40 via male and female sockets. Before fixing the flexible circuit board 40, the first collecting plate 20 and the second collecting plate 30 can be installed in the corresponding positions of the flexible circuit board 40 and then fixed to the vehicle body 10. Alternatively, the flexible circuit board 40 can be fixed to the vehicle body 10 first and then the first collecting plate 20 and the second collecting plate 30 are installed.

[0076] It can be understood that the drive motor 61 is disposed in the second section 12 of the vehicle body equipment and serves as the second electrical component 60 and is electrically connected to the second collecting plate 30 of the vehicle body equipment.

[0077] Specifically, the rear-wheel drive motor 61 is a hub motor, and a tire is mounted on the outer ring of the hub of the rear-wheel drive motor 61.

[0087] Specifically, the front frame 13 is located at the front end 111 of the vehicle body, the end of the main beam 14 close to the front frame 13 is located at the middle portion 112 of the vehicle body, and the other end of the main beam 14 and the rear frame 15 are located in the second section 12. It can be understood that the front end 111 of the vehicle body includes the front frame 13, and the middle portion 112 of the vehicle body includes the end of the main beam 14 close to the front frame 13.

[0088] In one embodiment of the present application, the vehicle body 10 further includes a connecting structure 16. The front frame 13 is fixed to the main beam 14, and the front frame 13 and the main beam 14 are integrally formed, while the rear frame 15 is a separate structure from the main beam 14, and the rear frame 15 is mounted to the end of the main beam 14 via the connecting structure 16.

[0089] When assembling the first electrical component 50 and the second electrical component 60, the front electrical component 55 can be installed on the front frame 13, the second electrical component 60 can be installed on the rear frame 15, the middle electrical component 56 and the third electrical component can be installed on the main beam 14, and then the rear frame 15 can be assembled to the main beam 14 through the connecting structure 16. Electrical components at different positions can be installed in parallel, which can effectively improve assembly efficiency, especially when there are many electrical devices.

[0090] Specifically, the rotating connection structure 16 is disposed at one end of the main beam 14 near the rear frame 15, and is rotationally connected to the rear frame 15. A channel is provided inside the rotating connection structure 16, and the channel is configured to allow cables to pass through. The cables of the rear wheel drive motor 61 pass through the channel and are electrically connected to the second collecting plate.

[0091] In one embodiment of the present application, the rotational connection structure 16 may include a connecting sleeve and a rotational sleeve. The connecting sleeve is fixed to one end of the main beam 14 via bolts. The rotational sleeve is rotationally connected to one end of the connecting sleeve, and the rotational sleeve is also bolted to the rear frame 15. The rotational connection between the connecting sleeve and the rotational sleeve realizes the rotational connection between the main beam 14 and the rear frame 15, and a channel is formed inside the connecting sleeve.

[0092] It is understandable that the above-mentioned rotating connection structure can also be replaced by other rotating structures in the art, as long as it can achieve the function of realizing the rotational connection between the main beam 14 and the rear frame 15 and allowing cables to pass through.

[0093] In some feasible embodiments, the front frame 13 and the main beam 14 can also be set as a split structure, and the front frame 13 is connected to the end of the main beam 14 through another connecting structure 16, that is, the front frame 13 and the rear frame 15 are respectively assembled at the two ends of the main beam 14.

[0094] See also Figure 2 and Figure 3In one embodiment of the present application, the main beam 14 extends in the longitudinal direction of the vehicle body 10. The main beam 14 is a shell structure, and a housing 141 is provided within the main beam 14 for accommodating power connection structures or electrical devices. The main beam 14 is also provided with a cover plate that covers the housing 141.

[0095] The flexible printed circuit board 40 is adhesively bonded to the inner bottom of the main beam 14 and laid along the length of the main beam 14. The first collecting plate 20 is fixed to the front frame 13 and the main beam 14, while the second collecting plate 30 is fixed to the end of the main beam 14 near the rear frame 15. Specifically, the front terminal plate 22 is fixed to the front frame 13, and the middle sub-plate 23 is fixed to the end of the main beam 14 near the front frame 13.

[0096] It is worth noting that the embodiment of the present application utilizes a design in which the front frame 13 is fixed to the main beam 14. When laying and fixing the flexible circuit board 40, the front terminal board 22 can be directly fixed to the front frame 13, and the middle sub-board 23 can be fixed to one end of the main beam 14.

[0097] Since the rear frame 15 and the main beam 14 are separate structures, the second collecting plate 30 is directly fixed to the other end of the main beam 14 instead of being fixed to the rear frame 15 , which can improve the installation efficiency of the flexible circuit board 40 .

[0098] Moreover, since the front frame 13 and the main beam 14 are an integral fixed structure and are not easy to separate, they can provide better support for the flexible circuit board 40, reduce damage to the flexible circuit board 40, and maintain the integrity and working stability of the flexible circuit board 40.

[0099] In some feasible embodiments, if the rear frame 15 is fixed to the main beam 14, and the front frame 13 and the main beam 14 are separate structures, the front terminal plate 22 can also be fixed to one end of the main beam 14 close to the front frame 13, and the second collecting plate 30 can be fixed to the rear frame 15 to achieve the same technical effect as mentioned above. The specific design can be made according to actual conditions.

[0100] See also Figure 2 and Figure 7 In one embodiment of the present application, the front wheel drive motor 51 and the charging head 53 are both fixed to the lower part of the front frame 13 through a bracket structure, wherein the charging head 53 includes two symmetrically distributed charging plates.

[0101] In one embodiment of the present application, the control module 54 is mounted and fixed to one end of the main beam 14 close to the front frame 13 , and the battery pack 62 is mounted and fixed to one end of the main beam 14 close to the rear frame 15 .

[0102] In one embodiment of the present application, the front frame 13 and the main beam 14 are angled with each other. The front frame 13 is arranged in a vertical direction as a whole. The front frame 13 is equivalent to a structure extending downward from one end of the main beam 14, so that an installation space 142 is left between the front frame 13 and the main beam 14. The installation space 142 is used to install the mowing device 52.

[0103] By utilizing the angle setting between the front frame 13 and the main beam 14, on the one hand, a certain wiring space is reserved in the vertical direction for the cables of the front terminal board 22 and the front wheel drive motor 51, which is convenient for cable assembly. On the other hand, an installation space 142 is reserved for the installation of the mowing device 52, which is convenient for the installation of the mowing device 52.

[0104] See also Figure 2 and Figure 3 In one embodiment of the present application, the mowing device 52 includes a connector 521, a lifting device 522, and a cutting tool 523. The connector 521 is used to connect to the front frame 13, the front terminal board 22 is installed on the side of the front frame 13 away from the installation space 142, and the connector 521 is installed on the side of the front frame 13 close to the installation space 142.

[0105] The lifting device 522 is used to drive the cutting tool 523 to move up and down, and the cutting tool 523 is used to perform cutting operations. The cables of the lifting device 522 and the cables of the cutting tool 523 are integrated into a terminal and connected to the front terminal board 22.

[0106] In some feasible embodiments, if the mowing device 52 needs to be fixed to the rear end of the vehicle body 10 , the connector 521 can also be installed to the rear frame 15 or the main beam 14 .

[0107] See also Figure 8 The present application also provides a method for installing a lawn mower, which is used to install the lawn mower in the above embodiment. The installation method includes the following steps.

[0114] The connection terminals of the first electrical device 50 are arranged and connected to the first collecting plate 20 , thereby achieving electrical connection between the first electrical device 50 and the first collecting plate 20 .

[0115] Since the first electrical components 50 are all installed in the first section 11, the positions of all the first electrical components 50 are close to the first collecting plate 20. Therefore, the wiring distance and cable length of the first electrical components 50 can be shortened, the cable assembly efficiency of the first electrical components 50 can be improved, and the cables of the first section 11 can be easily collected and managed.

[0116] S805 , connecting the connection terminal of the second electrical device 60 to the second collecting plate 30 .

[0117] The connection terminals of the second electrical device 60 are arranged and connected to the second collecting plate 30 to realize the electrical connection between the second electrical device 60 and the second collecting plate 30 , and realize the electrical connection between the first electrical device 50 and the second electrical device 60 .

[0118] Since the second electrical components 60 are all installed in the second section 12, the positions of all the second electrical components 60 are close to the second collecting plate 30. Therefore, the wiring distance and cable length of the second electrical components 60 can be shortened, the cable assembly efficiency of the second electrical components 60 can be improved, and the cables of the second section 12 can be easily collected and managed.

[0119] It can be understood that the purpose of step S801 is to complete the installation of the electrical connection structure, the purpose of steps S802-step S803 is to complete the installation of the electrical device, and the function of steps S804-step S805 is to complete the wiring assembly between the electrical connection structure and the electrical device.

[0121] In actual application scenarios, the order of implementing the above steps can be changed according to actual requirements such as the installation conditions of the electrical device, the installation sequence of the electrical device, the wiring method of the electrical device, etc. For example, in some feasible embodiments, the electrical device can be installed first, then the electrical connection structure can be installed, and then the wiring assembly between the electrical connection structure and the electrical device can be completed.

[0122] In some feasible embodiments, the three steps of the installation method, namely, installation of the electrical device, installation of the electrical connection structure, and wiring assembly between the electrical connection structure and the electrical device, may be performed alternately or in parallel. This application is not limited to this.

[0123] The installation method of the lawn mower provided in the embodiment of the present application is that after the flexible circuit board 40 is installed on the vehicle body 10, the cables of the first section 11 are collected and connected by using the first collecting plate 20, and the cables of the second section 12 are collected and connected by using the second collecting plate 30, thereby simplifying the cable distribution of the first section 11 and the second section 12, and the use of the flexible circuit board 40 can simplify the cable distribution between the first collecting plate 20 and the second collecting plate 30, thereby simplifying the cable layout of the entire lawn mower vehicle, reducing the difficulty of cable routing assembly, and improving assembly efficiency and production efficiency.
