Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, specifically a self-propelled lawnmower with an integrated lithium battery module. Background Technology

[0002] With the improvement of people's living standards and the continuous construction and development of garden landscapes, lawnmowers, as a common garden tool, play a vital role in areas such as lawn maintenance. However, existing lawnmowers, especially self-propelled lawnmowers with integrated lithium battery modules, still have some problems that urgently need to be solved.

[0003] Traditional lawnmowers are used relatively infrequently, remaining inactive most of the time. During this idle period, the lithium battery is typically removed for easier management and maintenance. However, the socket on the lawnmower used to connect the lithium battery has some design flaws, lacking effective sealing and protection. This makes it highly susceptible to external environmental factors and other adverse conditions when exposed for extended periods. For example, dust, moisture, and other foreign objects can easily enter the socket, causing poor contact, short circuits, or even damage. Furthermore, frequent plugging and unplugging operations and prolonged exposure cause the metal contacts of the socket to wear and oxidize, further reducing its reliability and lifespan, and increasing maintenance costs and the risk of failure.

[0004] At the same time, the existing connection method between lithium batteries and lawnmowers has many inconveniences. The process of disassembling and installing lithium batteries is relatively cumbersome, requiring a certain amount of time and effort, which leads to a decrease in work efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a self-propelled lawnmower with an integrated lithium battery module to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A self-propelled lawnmower with an integrated lithium battery module includes a vehicle body, a controller, and a lithium battery. The controller is mounted on the vehicle body and has a socket. The lithium battery has a plug that is compatible with the socket.

[0008] A battery compartment is slidably disposed on the vehicle body along its length, and the lithium battery is detachably disposed in the battery compartment. A dustproof plate that can seal the socket is vertically slidably disposed on the vehicle body, and the dustproof plate is connected to the battery compartment through a linkage structure.

[0009] The vehicle body is equipped with a locking assembly that works in conjunction with the battery compartment. When the battery compartment moves the lithium battery toward the controller, the linkage structure will cause the dust cover to move vertically upward and expose the socket. At the same time, the locking assembly will also activate. When the plug and socket are connected, the locking assembly can lock the battery compartment onto the vehicle body.

[0010] As a further embodiment of this utility model:

[0011] The linkage structure includes a guide rod and a connecting rod, with the guide rod vertically sliding on the vehicle body;

[0012] The bottom of the guide rod is fixedly connected to the top of the dustproof plate, and the two ends of the connecting rod are rotatably connected to the top of the battery compartment and one side wall of the dustproof plate, respectively.

[0013] As a further improvement of this utility model:

[0014] A spring is fitted on the outer wall of the guide rod, and the two ends of the spring abut against the top of the dustproof plate and the inner top of the vehicle body, respectively, so as to drive the dustproof plate to always have a downward tendency to seal the socket.

[0015] As a further improvement of this utility model:

[0016] The locking assembly includes a rotating rod that is horizontally rotatably mounted on the vehicle body along the length of the vehicle body and a sleeve mounted on the battery compartment, wherein the sleeve is slidably mounted on the outer wall of the rotating rod;

[0017] The rotating rod is equipped with a stop bar, which cooperates with the battery compartment. When the battery compartment moves the lithium battery closer to the controller, the rotating rod will first remain stationary and then rotate the stop bar. When the plug and socket are connected, the side of the stop bar closer to the controller abuts against the end of the battery compartment away from the controller.

[0018] As a further improvement of this utility model:

[0019] The outer wall of the rotating rod is provided with a straight groove and a spiral groove along its length, and the straight groove and the spiral groove are interconnected.

[0020] The inner wall of the sleeve is fitted with rolling steel balls, which are also fitted into the spiral groove. A knob is coaxially provided at one end of the rotating rod.

[0021] As a further improvement of this utility model:

[0022] The vehicle body is equipped with a drive assembly, which includes a motor and rollers;

[0023] The motor is vertically mounted on the vehicle body and is electrically connected to the controller. The roller is rotatably mounted on the vehicle body via a rotating shaft.

[0024] As a further improvement of this utility model:

[0025] The output end of the motor is equipped with a blade, and a drive shaft is horizontally rotatable on the vehicle body. A first bevel gear and a second bevel gear are coaxially mounted at both ends of the drive shaft.

[0026] A third bevel gear, which meshes with the first bevel gear, is coaxially arranged on the outer wall of the motor output end, and a fourth bevel gear, which meshes with the second bevel gear, is coaxially arranged on the rotating shaft.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] This application, on the one hand, achieves convenient installation and removal of lithium batteries by setting a sliding battery compartment on the vehicle body that is compatible with the controller socket, and a vertically sliding dustproof plate linked to the battery compartment. When it is necessary to remove the lithium battery, the battery compartment can be easily slid along the length of the vehicle body, allowing the lithium battery to detach from the controller socket. At the same time, the linkage structure drives the dustproof plate to move vertically downward, sealing and protecting the socket. This effectively avoids the problem of the controller socket being damaged by environmental factors such as dust and moisture due to long-term exposure when the lawnmower is idle, greatly extending the service life of the socket, reducing equipment maintenance costs and failure risks, and improving the overall reliability and durability of the lawnmower.

[0029] On the other hand, the locking mechanism further optimizes the stability and safety of the connection between the lithium battery and the lawnmower. When the battery compartment moves the lithium battery closer to the controller and the plug and socket are connected, the locking mechanism can act in time to firmly lock the battery compartment to the vehicle body. This ensures that the electrical connection between the lithium battery and the controller is stable and reliable during the operation of the lawnmower, thereby guaranteeing the normal operation and efficiency of the lawnmower and making the installation and removal of the lithium battery more convenient, efficient and safe.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Furthermore, the elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0042] Please see Figures 1-9In this embodiment of the utility model, a self-propelled lawnmower with an integrated lithium battery module includes a vehicle body 1, a controller 2 and a lithium battery 3. The controller 2 is mounted on the vehicle body 1 and is provided with a socket 201. The lithium battery 3 is provided with a plug 301 that is compatible with the socket 201.

[0043] A battery compartment 4 is slidably disposed on the vehicle body 1 along its length direction. The lithium battery 3 is detachably disposed in the battery compartment 4. A dustproof plate 5 that can seal the socket 201 is vertically slidably disposed on the vehicle body 1, and the dustproof plate 5 is connected to the battery compartment 4 through a linkage structure.

[0044] A locking assembly is provided on the vehicle body 1. The locking assembly cooperates with the battery compartment 4. When the battery compartment 4 moves the lithium battery 3 closer to the controller 2, the linkage structure will move the dustproof plate 5 vertically upward and expose the socket 201. At the same time, the locking assembly will also be activated. When the plug 301 and the socket 201 are connected, the locking assembly can lock the battery compartment 4 onto the vehicle body 1.

[0045] In this solution, in the initial state: when the lawnmower is in storage or idle state, the lithium battery 3 can be removed from the battery compartment 4. At this time, the battery compartment 4 is located at one end of the vehicle body 1, maintaining a certain distance from the controller 2. Under the action of the linkage structure, the dustproof plate 5 is in a vertically downward closed position, completely covering and sealing the socket 201 on the controller 2, preventing dust, moisture and other foreign objects from entering the socket 201 and protecting the socket 201 from environmental factors.

[0046] Installing the lithium battery 3: When the lawnmower needs to be used, first put the lithium battery 3 into the battery compartment 4. Then, push the battery compartment 4 so that it slides along the length of the vehicle body 1 toward the location of the controller 2. As the battery compartment 4 moves, the linkage mechanism is triggered, causing the dust cover 5 to move vertically upward. When the battery compartment 4 carrying the lithium battery 3 continues to move closer to the controller 2, the dust cover 5 gradually moves away, and the socket 201 gradually appears, preparing for the connection between the plug 301 of the lithium battery 3 and the socket 201.

[0047] Plug-in and locking: When the battery compartment 4 is moved to the appropriate position so that the plug 301 on the lithium battery 3 is aligned with the socket 201 on the controller 2 and plugging begins, the locking component starts to operate. As the plug 301 and socket 201 gradually tighten together, the locking component completes the locking action, firmly fixing the battery compartment 4 to the vehicle body 1. This ensures that the electrical connection between the lithium battery 3 and the controller 2 is stable and reliable during the operation of the lawnmower, and will not become loose or have poor contact due to machine vibration or movement.

[0048] When the lawnmower is working, the lithium battery 3 provides power to the lawnmower's motor 14 and other components through an electrical connection with the controller 2. The controller 2 is responsible for regulating the various operations of the lawnmower to ensure that the machine performs lawnmowing operations according to the preset program and mode. It should be noted that the controller 2 adopts existing technology and is not an improvement point of this application.

[0049] Removing lithium battery 3: After the lawnmower finishes working, if it is necessary to remove lithium battery 3, operate the locking component to release its lock on battery compartment 4. Then, slide battery compartment 4 outward along the length of vehicle body 1. At the same time, the linkage structure drives dustproof plate 5 to move vertically downward, re-sealing and protecting socket 201 until battery compartment 4 is completely removed from vehicle body 1, and lithium battery 3 is safely removed.

[0050] As a further embodiment of this utility model, the linkage structure includes a guide rod 6 and a connecting rod 7, wherein the guide rod 6 is vertically slidably disposed on the vehicle body 1;

[0051] The bottom of the guide rod 6 is fixedly connected to the top of the dustproof plate 5, and the two ends of the connecting rod 7 are rotatably connected to the top of the battery compartment 4 and one side wall of the dustproof plate 5, respectively.

[0052] A spring 8 is fitted on the outer wall of the guide rod 6. The two ends of the spring 8 abut against the top of the dustproof plate 5 and the inner top of the vehicle body 1, respectively, so as to drive the dustproof plate 5 to always have a downward tendency to seal the socket 201.

[0053] In this embodiment, when the battery compartment 4 is in a position away from the controller 2, the spring 8 is in a natural state or a slightly compressed state. At this time, the dustproof plate 5 is kept vertically downward under the action of the spring 8, tightly covering the socket 201 of the controller 2, so as to achieve effective sealing protection of the socket 201.

[0054] When the lithium battery 3 needs to be installed on the lawnmower, the battery compartment 4 is pushed closer to the controller 2 along the length of the vehicle body 1. As the battery compartment 4 moves, the two ends of the connecting rod 7 start to function at the rotation connection points of the top of the battery compartment 4 and one side of the dust cover 5, respectively. The movement of the battery compartment 4 drives one side of the dust cover 5 to rotate upward through the connecting rod 7. At the same time, the bottom of the guide rod 6 is fixedly connected to the top of the dust cover 5, so that as the dust cover 5 moves upward, it drives the guide rod 6 to slide vertically upward on the vehicle body 1. At this time, the spring 8 is further compressed, and its two ends abut against the top of the dust cover 5 and the inner top of the vehicle body 1, respectively, generating a downward elastic force. However, this force is overcome by the linkage of the guide rod 6 and the connecting rod 7, so that the dust cover 5 remains in a vertically upward state, exposing the socket 201, so that the plug 301 of the lithium battery 3 can be inserted into the socket 201.

[0055] As the battery compartment 4 moves the lithium battery 3 closer to the controller 2, until the plug 301 and socket 201 are fully connected, the locking component is activated to lock the battery compartment 4 onto the vehicle body 1. At this time, the linkage structure remains stable, and the dustproof plate 5, under the combined action of the guide rod 6 and the connecting rod 7, continues to be in a vertically upward position to ensure that the socket 201 is fully exposed, thus realizing the electrical connection between the lithium battery 3 and the controller 2.

[0056] Throughout the process, the spring 8 always applies a downward elastic force to the dust cover 5, so that when the battery compartment 4 is not locked or in a non-working state, the dust cover 5 can automatically move down and fit tightly against the socket 201, thus providing a sealing protection. This linkage structure realizes the synchronous and coordinated movement of the battery compartment 4 and the dust cover 5, which not only ensures the convenience of lithium battery 3 installation process, but also effectively protects the socket 201 of the controller 2, preventing it from being damaged by environmental factors when not in operation, thereby improving the reliability and service life of the lawnmower.

[0057] As a further embodiment of the present invention, the locking assembly includes a rotating rod 9 that is horizontally rotatably disposed on the vehicle body 1 along the length direction of the vehicle body 1 and a sleeve 10 disposed on the battery compartment 4, wherein the sleeve 10 is slidably sleeved on the outer wall of the rotating rod 9.

[0058] The rotating rod 9 is provided with a stop rod 11, which cooperates with the battery compartment 4. When the battery compartment 4 moves the lithium battery 3 closer to the controller 2, the rotating rod 9 will first remain stationary and then drive the stop rod 11 to rotate. When the plug 301 and the socket 201 are connected, the side of the stop rod 11 closer to the controller 2 abuts against the end of the battery compartment 4 away from the controller 2.

[0059] The outer wall of the rotating rod 9 is provided with a straight groove 901 and a spiral groove 902 along its length direction, and the straight groove 901 and the spiral groove 902 are interconnected.

[0060] The inner wall of the sleeve 10 is fitted with a rolling steel ball 12, which is also fitted into the spiral groove 902. A knob 13 is coaxially provided at one end of the rotating rod 9.

[0061] In this embodiment, when the battery compartment 4 slides towards the controller 2, the sleeve 10 on it slides along the rotating rod 9. In the initial stage, the rotating rod 9 is stationary, the sleeve 10 moves relative to the rotating rod 9, and the steel ball 12 rolls in the straight groove 901. When the battery compartment 4 continues to move to a certain position, the steel ball 12 enters the spiral groove 902, pushing the rotating rod 9 to rotate. When the rotating rod 9 rotates, the stop rod 11 rotates accordingly. When the plug 301 and the socket 201 are plugged in, the side of the stop rod 11 near the controller 2 is exactly against the end of the battery compartment 4 away from the controller 2, thereby locking the battery compartment 4 and preventing it from sliding during operation. The rotating rod 9 can be manually rotated by the knob 13 to release the lock or relock it.

[0062] As a further embodiment of this utility model, a drive assembly is provided on the vehicle body 1, the drive assembly including a motor 14 and a roller 15;

[0063] The motor 14 is vertically mounted on the vehicle body 1 and is electrically connected to the controller 2. The roller 15 is rotatably mounted on the vehicle body 1 via a rotating shaft 16.

[0064] The output end of the motor 14 is provided with a blade 17, and a drive shaft 18 is horizontally rotatably mounted on the vehicle body 1. The two ends of the drive shaft 18 are respectively coaxially provided with a first bevel gear 19 and a second bevel gear 20.

[0065] The outer wall of the output end of the motor 14 is coaxially provided with a third bevel gear 21 that meshes with the first bevel gear 19, and the rotating shaft 16 is coaxially provided with a fourth bevel gear 22 that meshes with the second bevel gear 20.

[0066] In this embodiment, when the lawnmower is started, the motor 14 is powered on and runs under the control of the controller 2. The output end of the motor 14 drives the blade 17 to rotate, and at the same time drives the third bevel gear 21 to rotate; since the third bevel gear 21 meshes with the first bevel gear 19, the transmission shaft 18 is driven to rotate; the second bevel gear 20 on the transmission shaft 18 rotates accordingly and meshes with the fourth bevel gear 22, causing the rotating shaft 16 to rotate, driving the roller 15 to rotate, and propelling the lawnmower forward; the entire drive assembly transmits the rotational power of the motor 14 to the blade 17 and the roller 15 through the transmission of the bevel gear set, realizing the functions of mowing and walking.

[0067] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
