[0001] The utility model relates to the technical field of garden tools, in particular to a lawn mower. Background Art

[0002] As a garden tool, lawn mowers are widely used in lawn and vegetation trimming. Existing lawn mowers include handheld, hand-push, riding, and smart lawn mowers that do not require direct operation, depending on the different operating methods. With the popularization of lithium battery application technology, the use of batteries instead of engine drive has become a general trend. Existing tools powered by lithium batteries basically use detachable battery packs or fixed battery packs to provide power to the tools, especially large riding tools, most of which use a multi-pack parallel discharge method.

[0003] Chinese patent application publication number CN 212034865 U, named "Riding Lawn Mower", discloses a power supply device, which includes a battery pack that can provide energy and a battery compartment for accommodating the battery pack. The battery pack and the battery compartment for accommodating the battery pack are placed in a main compartment at the same time. The power supply device is assembled with the main frame through a connecting part, but the device has a complex structure and a cumbersome disassembly process, which is not conducive to heat dissipation and the connecting part cannot effectively protect the power supply device.

[0004] In order to overcome the deficiencies in the prior art, the utility model provides a lawn mower having the advantages of simple disassembly and assembly structure, low maintenance cost, simple disassembly and assembly method, high disassembly and assembly efficiency, and effective protection of a power supply device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A lawn mower comprises a body and a power supply device installed on the body, the power supply device comprises a battery compartment assembly, a bracket assembly and a power management module, the bracket assembly comprises a accommodating cavity, the battery compartment assembly is placed in the accommodating cavity and is detachably connected to the bracket assembly, a side wall of the accommodating cavity extends upward so that the side wall forms a mounting wall, and the power management module is placed on the outer side wall of the mounting wall and is detachably connected to the bracket assembly.

[0007] By adopting the above-mentioned technical solution, it can be known that the battery compartment assembly is placed in the accommodating cavity, and the accommodating cavity limits the battery compartment assembly by adapting with the battery compartment assembly, and one side of the accommodating cavity extends upward to form an installation wall, and the power management module is placed on the outer wall of the installation wall. The battery compartment assembly and the power management module are both detachably connected to the bracket assembly, and the battery compartment assembly and the power management module are respectively placed on opposite sides of the side wall surface. When one of the battery compartment assembly and the power management module fails, only the faulty part needs to be disassembled, and the installation structure is simple, disassembly is convenient, and disassembly efficiency is high.

[0008] Furthermore, the bracket assembly also includes a plurality of fixing columns, which are arranged opposite to the mounting wall and have the same height, and the battery compartment assembly is detachably connected to the fixing columns and the mounting wall.

[0009] By adopting the above-mentioned technical scheme, it can be known that a fixing column is provided on the side opposite to the side wall of the accommodating chamber, and a mounting hole is provided on the fixing column. After the battery compartment assembly is placed in the accommodating chamber, in order to avoid vertical shaking during the operation of the lawn mower, a fixing column is provided to be rigidly connected to one side of the battery compartment assembly, and a mounting hole connected to the battery compartment assembly is also provided on the mounting wall. The fixing column and the side wall are both at the same height as the battery compartment assembly. On the other side, the battery compartment assembly is also rigidly connected to the side wall. Furthermore, the battery compartment assembly is detachably connected to the bracket assembly. This connection method not only maintains the stability of the battery compartment assembly when the lawn mower is in operation, but also achieves convenient disassembly and assembly when the battery compartment assembly fails.

[0010] Furthermore, the battery compartment assembly is provided with a mounting hole, the fixing column and the mounting wall are provided with threaded holes, and screws pass through the mounting hole and are locked with the threaded holes.

[0011] By adopting the above technical solution, it can be known that the utility model adopts screw connection, which can make the connection between the battery compartment assembly and the bracket assembly more stable.

[0012] Furthermore, the bracket assembly also includes multiple groups of fixing parts, which are arranged on the outer wall of the installation wall. The power management module is provided with multiple groups of first mounting parts corresponding to the fixing parts, and the first mounting parts are detachably connected to the fixing parts.

[0013] By adopting the above-mentioned technical solution, it can be known that the outer wall of the mounting wall has at least one group of fixings for fixing the power management module on the side wall of the mounting wall. Similarly, the power management module is rigidly connected to the mounting wall through the fixings. Furthermore, the power management module is detachably connected to the bracket assembly. This connection method not only maintains the stability of the power management module when the lawn mower is in operation, but also facilitates disassembly and assembly when the power management module fails. Furthermore, placing the power management module on the outer wall can enable the power management module to dissipate heat better during operation, thereby avoiding excessive temperature, failure to dissipate heat, damage to components, and potential safety hazards.

[0014] Furthermore, the bracket assembly is also provided with a fixed connection bracket, the fixed connection bracket is arranged on the outer side wall of the installation wall, and the fixed connection bracket is fixedly connected to the body.

[0015] By adopting the above-mentioned technical solution, it can be seen that there is also a fixed connecting bracket on the outer wall of the mounting wall, and the fixed connecting bracket is rigidly connected to the mounting wall to ensure the stability of the bracket assembly and the battery compartment assembly and power management module installed on the bracket. The fixed connecting bracket is also provided with a mounting portion connected to the body, which is detachably connected to the body through a mounting plate. This structure is easy to disassemble and has a stable structure.

[0016] Furthermore, there are two fixed connection brackets, which are symmetrically arranged on opposite sides of the power management module. The fixed connection bracket includes a fixed section and a connecting section. One end of the fixed section is connected to the mounting wall, and the other end is connected to the connecting section. The connecting section is fixedly connected to the body.

[0017] By adopting the above technical solution, it can be known that the fixed connection bracket is symmetrically arranged, the fixed end of the fixed connection bracket is rigidly connected to the installation wall, and the connecting section of the fixed connection bracket is rigidly fixedly connected to the body.

[0018] The connecting section is L-shaped, half of the connecting section is wrapped around the outside of the power management module and there is a shock-absorbing gap between the connecting section and the power management module.

[0019] By adopting the above-mentioned technical solution, it can be seen that the connecting section ring is in front of the power management module, and the power management module is placed between the mounting wall and the connecting section. Since the above-mentioned fixed section is rigidly connected to the mounting wall, there is still a gap between the fixed connecting bracket and the mounting wall surface that is sufficient to place the power management module. Furthermore, the connecting section of the above-mentioned fixed connecting bracket is L-shaped, and the gap can also play a buffering role in the event of a collision to avoid damage to the power management module.

[0020] Furthermore, according to the above-mentioned lawn mower, each group of fixing parts includes two fixing parts symmetrically arranged on opposite sides of the power management module, and the bracket assembly includes two groups of fixing parts, one group is arranged near the top of the installation wall, and the other group is arranged near the bottom of the installation wall.

[0021] By adopting the above-mentioned technical solution, it can be known that the power management module has a fixing part fixed to the bracket assembly. In order to make the installation more stable, two groups of fixing parts are set, and the installation positions are set at the top and bottom of the power management module. Furthermore, since the bottom of the power management module is lower than the bottom of the outer wall of the accommodating cavity, one group of the fixing parts is set to extend downward and be detachably connected to the first position. This connection method can achieve the best effect between the power management module and the bracket assembly.

[0022] The bracket assembly is provided with a plurality of through holes, and the through holes are arranged at the bottom of the side wall of the accommodating cavity, and the wiring harness on the power management module extends into the accommodating cavity through the through holes.

[0023] By adopting the above-mentioned technical solution, it can be known that a plurality of through holes are provided at the bottom of the side wall of the accommodating cavity for connecting the power management module with the battery compartment assembly. Furthermore, the through holes are blocked by the power management module to prevent the wiring harness from being exposed and damaging the wiring harness when the lawn mower is in operation.

[0024] The power management module includes a power module and a protection device, and the protection device is detachably connected around the power module.

[0025] By adopting the above technical solution, it can be known that the power management module is placed on the outer wall. In order to avoid damage to the power module due to collision when the lawn mower is in operation, a protective device is provided to further protect the power module. The above installation positions are all set on the protective device.

[0026] The beneficial effects of the utility model are: (1) simple structure and low manufacturing cost; (2) simple disassembly and assembly method and high disassembly and assembly efficiency; (3) effective protection of the power management module and the battery compartment assembly.

[0035] It can be understood that the battery compartment assembly 1 is placed in the accommodating cavity 24, and the accommodating cavity 24 limits the battery compartment assembly 1 by adapting to the battery compartment assembly 1. One side of the accommodating cavity 24 extends upward to form a mounting wall 242, and the power management module 3 is placed on the outer wall of the mounting wall 242. The battery compartment assembly 1 and the power management module 3 are both detachably connected to the bracket assembly 2, and the battery compartment assembly 1 and the power management module 3 are respectively placed on opposite sides of the side wall. When one of the battery compartment assembly 1 and the power management module 3 fails, only the faulty part needs to be disassembled. The installation structure is simple, disassembly is convenient, and disassembly efficiency is high.

[0036] Further preferably, the accommodating cavity 24 in the present embodiment is shown as a rectangle. In actual application, there is no limitation on the specific shape of the accommodating cavity 24. It only needs to achieve the purpose of limiting the battery compartment assembly 1 by the accommodating cavity 24. For example, it can be a triangle, a circle, etc. More specifically, it depends on the actual use requirements.

[0037] Embodiment 2:

[0038] Based on Example 1, it can be known that the bracket assembly 2 also includes two fixing columns 22, which are arranged opposite to the mounting wall 242 and have the same height, and the battery compartment assembly 1 is detachably connected to the fixing columns 22 and the mounting wall 242. A mounting hole 11 is provided on the battery compartment assembly 1, and threaded holes 221 are provided on the fixing columns 22 and the mounting wall 242. The battery compartment assembly 1 is rigidly connected to the fixing columns 22 and the mounting wall 242 by screws passing through the mounting holes 11 and the threaded holes 221.

[0039] It can be understood that two fixing columns 22 are provided on the side opposite to the mounting wall 242, and threaded holes 221 are provided on the fixing columns 22. After the battery compartment assembly 1 is placed in the accommodating cavity 24, in order to avoid vertical shaking during the operation of the lawn mower, the fixing columns 22 are rigidly connected to one side of the battery compartment assembly 1 by setting the fixing columns 22, and the threaded holes 221 connected to the battery compartment assembly 1 are also provided on the side wall surface. The fixing columns 22 and the side wall surface are both at the same height as the battery compartment assembly 1. On the other side, the battery compartment assembly 1 is also rigidly connected to the side wall surface. Furthermore, the battery compartment assembly 1 is also fixedly connected to the bracket assembly 2 with screws and nuts. This connection method not only maintains the stability of the battery compartment assembly 1 when the lawn mower is in operation, but also achieves convenient disassembly and assembly when the battery compartment assembly 1 fails.
