Description

TECHNICAL FIELD

[0001] The utility model relates to the lawn mower technical field especially, and it is a detachable electricity connection wire module and lawn mower. BACKGROUND

[0002] In the wave of science and technology, we witness the rapid rise of intelligent electric tools and devices, which play an indispensable role in our daily life. From automatic sweeping robots to intelligent lawn mowers, these innovative devices not only greatly improve our work efficiency, but also improve our quality of life in an invisible way. They can automatically perform tasks such as cleaning or trimming lawns according to the preset schedule, and after completing the task, they can intelligently return to the charging seat for charging, realizing true automation and bringing unprecedented convenience to users.

[0003] However, for intelligent devices to run stably, a reliable power connection module is essential. In actual application, the existing power connection module often has some shortcomings, especially on outdoor large devices, and these limitations are magnified. Taking intelligent lawn mowers as an example, they often need to work in an environment full of vibration, high humidity and many grass leaves, which puts higher requirements on the power connection module. In order to ensure the normal use of the power connection function, the power connection module often needs to be cleaned and maintained regularly, or even replaced. Unfortunately, the power connection module of the existing outdoor large device is not designed to be user-friendly and is difficult to disassemble, which undoubtedly increases the difficulty of daily maintenance and replacement.

[0004] In addition, the existing technology of the lawn mower power connection module lacks effective wire management function, which not only affects the neatness of the device, but also increases the workload during maintenance and replacement. In this case, an easily detachable, easy-to-maintain power connection module with good wire management function is particularly important. Utility model content

[0005] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a detachable power connection and wire management module and a lawn mower, which solves the problem of difficult installation and removal of the power connection module of the lawn mower in the prior art, and the large workload of maintenance and replacement caused by difficult wire management.

[0006] In order to solve the above technical problems, the utility model provides a detachable power connection and wire management module, which is used to detachably and install the main body, and assists the power supply cable and power supply plug of the installation main body to connect, comprising:

[0007] The protective shell comprises a frame, a bottom plate covering the bottom of the frame, and positioning ribs arranged on the bottom plate, which together form independent electrode cavities and wire arranging cavities. The protective shell is provided with an electricity connection port adapted to a power supply plug, and the electricity connection port is in communication with the electrode cavities. The frame further comprises positioning ribs adapted to a mounting body and fixing holes.

[0008] During installation, the positioning ribs are used to position the mounting body, and the protective shell is detachably locked on the mounting body through the fixing holes by fixing screws. The mounting body covers the top of the protective shell, and the power supply cable enters the wire arranging cavities through the mounting body and then enters the electrode cavities.

[0009] The power supply plug is inserted into the electricity connection port and is in communication with the power supply cable in the electrode cavities.

[0010] As a more preferred mode, the detachable electricity connection and wire arranging module further comprises a spring sheet fixed in the electrode cavities. The power supply cable enters the electrode cavities by connecting with the spring sheet. The spring sheet has a certain elasticity. When the power supply plug is inserted into the electrode cavities, the pins of the power supply plug press the spring sheet, and the spring sheet is in closer contact with the pins of the power supply plug under the action of the elastic force, thereby improving the stability of electricity connection.

[0011] As a more preferred mode, the detachable electricity connection and wire arranging module comprises two electrode cavities corresponding to the positive and negative poles of the power supply plug, respectively. The separately arranged electrode cavities greatly reduce the risk of short circuit between the positive and negative poles and improve safety.

[0012] As a more preferred mode, the two electrode cavities are arranged on the two sides of the wire arranging cavities. In this way, the power supply cables connecting the two electrode cavities enter the wire arranging cavities from their corresponding sides, reducing the length of the power supply cables and ensuring the symmetrical distribution of the power supply cables, so that the power supply cables are more reasonably arranged.

[0013] As a more preferred mode, the bottom plate is provided with drainage holes corresponding to the electrode cavities and the wire arranging cavities. The accumulated water in the electrode cavities and the wire arranging cavities can be drained through the drainage holes, avoiding the accumulation of water in the electrode cavities and the wire arranging cavities and reducing the influence of water accumulation on system stability.

[0014] As a more preferred mode, the positioning ribs are arranged in pairs on the two sides of the electricity connection port, and one end extends inward of the electricity connection port to guide the insertion of the power supply plug, thereby improving the success rate of the butt joint of the power supply plug and the electricity connection port.

[0015] The bottom plate further comprises a limiting column, and a wire slot is formed in the end of the limiting column, which is used to assist the wire arrangement of the power cable, and the wire arrangement of the power cable is controlled, thereby achieving part of the wire arrangement requirement and making the wire arrangement of the power cable more reasonable.

[0016] To solve the above problems, the utility model further provides a mower, which comprises

[0017] The mower body;

[0018] The detachable power connection and wire arrangement module is detachably fixed with the mower body.

[0019] As a more preferred mode, the corresponding position of the mower body is provided with a positioning groove and a fixing column matched with the positioning convex edge and the fixing hole, the positioning convex edge is inserted into the positioning groove, and the detachable power connection and wire arrangement module is detachably fixed with the mower body by using the fixing screw passing through the fixing hole and the fixing column.

[0020] As a more preferred mode, the mower body is provided with a threading hole aligned with the wire arrangement cavity, one end of the power cable passes through the threading hole into the wire arrangement cavity, and then is connected with the electrode cavity.

[0021] As a more preferred mode, the mower body further comprises a sealing ring covering the threading hole, so that water vapor cannot enter the mower body through the threading hole, the electrical equipment in the mower body is protected, and the stability of the equipment is improved.

[0022] As described above, the detachable power connection and wire arrangement module and the mower have the following beneficial effects: when the detachable power connection and wire arrangement module is installed, the positioning convex edge is used for positioning with the installation body, and then the fixing screw passes through the fixing hole to detachably lock the protective shell on the installation body, the installation body covers the top of the protective shell, the power cable passes through the installation body into the wire arrangement cavity, and then is connected with the electrode cavity; it can be seen that the detachable power connection and wire arrangement module of the utility model is detachably installed with the installation body only by two steps of positioning by the positioning convex edge and tightening the fixing screw, and similarly, only by loosening the fixing screw can the installation and dismounting of the power connection module be completed, which greatly facilitates the installation and dismounting of the power connection module; the wire arrangement cavity also ensures the accommodation of the excess wire harness and avoids the disorder of the wire harness.

[0023] The mower adopts the detachable power connection and wire arrangement module, which facilitates the steps of daily maintenance, installation and dismounting of the power connection module, makes the internal bus of the mower more orderly and reasonable, and greatly reduces the work burden of daily maintenance of the mower.

[0024] The detachable power connection and wire arrangement module and the lawn mower have the advantages that the detachable power connection and wire arrangement module and the wire arrangement cavity designed through the quick release structure realize quick assembly and disassembly of the connection module and orderly storage of the wire harness, and solve the problems of difficult assembly and disassembly of the power connection module of the lawn mower in the prior art, and large maintenance and replacement workload caused by difficult wire arrangement.
