Description

Technical Field

[0001] This utility model relates to the field of garden tools, and in particular to an intelligent lawnmower. Background Technology

[0002] Smart lawnmowers often need to be compatible with different battery packs, and these battery packs typically use different conversion protocols. To achieve compatibility with different communication protocols, smart lawnmowers usually employ a solution with an internal relay PCB board and an external battery pack. However, this design also has significant drawbacks. As an additional electronic component, the relay PCB board is prone to failure in harsh outdoor environments such as humidity and dust during long-term use, becoming a bottleneck in system reliability. Furthermore, with the continuous evolution of battery technology and communication protocols, the built-in relay PCB board may need to be updated or replaced to adapt to newer batteries. Repairing or replacing this board often requires disassembling the entire machine, which is complex, inconvenient, and increases the user's operating costs and time burden. Utility Model Content

[0003] The purpose of this invention is to provide an intelligent lawnmower that solves the problem of inconvenient use of the transfer PCB board in the prior art, making the transfer PCB board more convenient to use and easier to maintain later.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent lawnmower, comprising a lawnmower body, a battery pack, and a transfer PCB board for converting the charging protocol of the battery pack into a protocol compatible with the lawnmower body. The lawnmower body is provided with a battery compartment, and the intelligent lawnmower also includes a housing box. The battery pack and the transfer PCB board are installed in the housing box, which can be installed in the battery compartment. The housing box is provided with a connector for electrically connecting the transfer PCB board located in the housing box and the lawnmower body.

[0005] By adopting the above technical solution, this utility model has the following advantages: By integrating the battery pack and the transfer PCB board into an independent housing box to form a pluggable integrated module, and fixing it in the battery compartment of the lawnmower body, not only is the overall reliability of the system improved, but the stability and durability of the equipment in complex outdoor environments are also enhanced. Simultaneously, with the development of battery pack technology and communication protocols, users only need to replace the corresponding built-in PCB board to support new battery packs, ensuring good technical continuity and compatibility of the product as much as possible. Furthermore, when maintenance or replacement of the transfer PCB board is required, there is no need to disassemble the entire lawnmower; simply remove the housing box from the battery compartment and replace the transfer PCB board inside the housing box to complete the maintenance. The operation process is simple and quick, effectively reducing maintenance difficulty and operating costs.

[0006] Furthermore, the accommodating box is provided with a accommodating cavity for accommodating different battery packs and a first opening for the battery packs to enter and exit the accommodating cavity, and the transfer PCB board is pre-installed in the accommodating cavity.

[0007] Using the aforementioned technical solution, the receiving cavity can be adapted to different sizes and types of battery packs, allowing the same receiving box to be compatible with multiple battery packs. Simultaneously, the overall dimensions of the receiving box remain uniform, achieving a standardized match with the battery compartment on the lawnmower body, thus ensuring the universality and consistency of mechanical installation. By replacing the receiving box module with different built-in battery packs and transfer PCBs, the lawnmower can adapt to new battery pack types or update communication protocols without altering the main body structure, demonstrating excellent expandability and technological continuity.

[0008] Furthermore, the battery compartment is provided with a second opening for the housing box to enter and exit. The lawnmower body is connected to a movable door that opens or closes the second opening. After the housing box is inserted into the battery compartment, the first opening and the second opening are located on the same side of the lawnmower body. The end of the housing cavity away from the first opening is provided with a mounting seat that abuts against the battery pack. After the movable door is closed, it abuts against the battery pack to limit the battery pack.

[0009] By adopting the aforementioned technical solution, the first opening and the second opening are located on the same side of the lawnmower body, which helps to unify the operation direction and improve the human-machine interaction. By setting a mounting seat at the end of the receiving cavity away from the first opening and applying a clamping force to the battery pack after the movable door is closed, the battery pack is limited in both directions in the receiving box, minimizing the loosening caused by vibration or impact during operation and improving the overall connection reliability. Furthermore, there is no need to set a separate cover or sealing structure for the first opening of the receiving box; the sealing function can be achieved solely by the movable door of the battery compartment. Users only need to operate one movable door to complete the entire battery module installation or replacement process, improving user operation convenience.

[0010] Furthermore, the mounting base includes an outward protrusion and a body portion connected to the outward protrusion. The outward protrusion protrudes from the body portion in the direction of the first opening to form a step portion between the outward protrusion and the body portion. The battery pack is provided with a protruding positioning portion, which abuts against the step portion. The transfer PCB board is disposed on the outward protrusion.

[0011] By employing the aforementioned technical solution, a stepped portion is provided on the mounting base as a positioning reference surface. The positioning portion on the battery pack can then tightly engage with this stepped portion, enabling rapid alignment and stable installation of the battery pack. Simultaneously, the transfer PCB board is positioned on the protruding portion of the mounting base, bringing it closer to the battery electrodes and effectively shortening the electrical connection path.

[0012] Furthermore, the positioning part is provided with a power transmission end, and the step part is provided with a power receiving end that contacts the power transmission end. The other end of the power receiving end is electrically connected to the transfer PCB board.

[0013] Through the above technical solution, the positioning part not only serves to limit the axial movement of the battery pack, but its power transmission end can also form stable contact with the power receiving end on the step part, thereby establishing a reliable electrical connection. During the process of inserting the battery pack into the housing, mechanical positioning and electrical connection can be completed simultaneously without additional operations, significantly simplifying the installation process and improving the ease of use and operational efficiency of the equipment.

[0014] Furthermore, there is an operating gap between the protrusion and the first opening for the user to place and remove the battery pack.

[0015] The above technical solution addresses the potential structural interference caused by the protruding portion during battery pack installation or removal. By creating an operating gap between the protruding portion and the first opening, this interference can be effectively avoided, improving operational smoothness. This operating gap provides users with space to insert their fingers or use auxiliary tools, facilitating battery pack placement and removal, significantly enhancing the convenience of module replacement and the human-machine interface. Simultaneously, while meeting operational requirements, this design maintains the structural integrity of the protruding portion, allowing it to continue fulfilling its functions of mounting, positioning, and supporting the intermediate PCB board, thus achieving a reasonable balance between functionality and structural strength.

[0016] Furthermore, there is a wiring gap between the top end face of the protrusion and the inner wall of the battery compartment, the top end face of the protrusion is provided with a protrusion, the protrusion has a receiving groove, and the transfer PCB board is installed in the receiving groove.

[0017] The above technical solution utilizes the wiring gap between the top of the protrusion and the inner wall of the battery compartment to provide a reasonable wiring channel for lead wires or connecting lines, effectively avoiding exposed cables or interference with other components, and improving the overall neatness and safety of the wiring. Simultaneously, integrating the transfer PCB board into the receiving groove formed by the protrusion achieves a spatial nesting layout of functional components, helping to reduce the overall module size and improve the compactness of the entire structure. This receiving groove not only effectively encloses and limits the transfer PCB board but also buffers external vibrations and impacts to a certain extent, preventing displacement or damage to the transfer PCB board as much as possible, thereby enhancing the structural stability and operational reliability of the transfer PCB board under complex operating conditions.

[0018] Furthermore, the connector includes a lead wire electrically connected to the transfer PCB board, and the battery compartment is provided with a dead wire. The lead wire and the dead wire are provided with dead terminals that are pluggable to each other.

[0019] Through the above technical solution, in traditional designs, some battery packs require physical insertion and removal to trigger the system wake-up mechanism. If the insertion and removal force is too great or the operation is inconvenient, it can easily cause user problems. The unplugged terminals typically adopt a standardized plug-in / plug-out interface design, with its insertion and removal force rationally set, making operation easy and providing a clear feel. Compared to directly plugging and unplugging the battery pack itself, it has lower operational difficulty and higher ease of use. When installing or replacing the housing module, users only need to connect or disconnect the unplugged terminals to establish or disconnect the electrical connection, eliminating the need to repeatedly plug and unplug the entire battery pack, thereby effectively reducing operational intensity and improving the human-machine interaction experience.

[0020] Furthermore, the accommodating box is provided with a wiring hole for the lead wire to pass through, and the connection position of the unused wire and the lead wire corresponds to the position of the wiring hole.

[0021] By employing the aforementioned technical solution, and through the rational layout of the wiring holes, corresponding them to the connection points of the unused wires and lead wires, the lead wires can be guided to exit the housing in an orderly manner, forming a simple and fixed wiring path with the unused wires in the battery compartment. This design helps ensure accurate alignment and connection between the lead wires and unused wires, minimizing difficulties in insertion and removal or poor contact caused by positional deviations, thereby improving assembly efficiency and the stability of electrical connections.

[0022] Furthermore, the lead wire passes through the gap between the battery pack and the housing to exit the wiring hole, and the battery pack installed in the housing abuts against the lead wire to press the lead wire firmly against the housing.

[0023] With the above technical solution, after the battery pack is placed into the housing, its outer wall contacts and applies pressure to the lead wires, pressing them firmly against the inside or side wall of the housing, forming a self-locking fixing structure. This design effectively constrains the lead wires without the need for additional clips, straps, or other cable fixing devices. It not only simplifies the housing structure but also significantly improves the stability and reliability of the lead wires, effectively preventing loosening or detachment due to vibration or insertion / removal operations during use, thereby ensuring the continuity and safety of the electrical connection.

[0041] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0042] like Figures 1 to 7 As shown, this utility model provides an intelligent lawnmower, including a lawnmower body 10, a battery pack 20, and a transfer PCB board 30 for converting the charging protocol of the battery pack 20 into a protocol compatible with the lawnmower body 10. The lawnmower body 10 is provided with a battery compartment 11. The intelligent lawnmower also includes a housing box 40. The battery pack 20 and the transfer PCB board 30 are installed in the housing box 40. The housing box 40 can be installed in the battery compartment 11. The housing box 40 is provided with a connector for electrically connecting the transfer PCB board 30 and the lawnmower body 10 located in the housing box 40.

[0043] By integrating the battery pack 20 and the transfer PCB board 30 into a separate housing 40, forming a pluggable integrated module, and fixing it in the battery compartment 11 of the lawnmower body 10, not only is the overall reliability of the system improved, but the stability and durability of the equipment in complex outdoor environments are also enhanced. Simultaneously, with the development of battery pack 20 technology and communication protocols, users only need to replace the corresponding built-in transfer PCB board 30 to support new battery packs 20, ensuring good technical continuity and compatibility of the product as much as possible. Furthermore, when maintenance or replacement of the transfer PCB board 30 is required, there is no need to disassemble the entire lawnmower; simply remove the housing 40 from the battery compartment 11 and replace the new transfer PCB board 30 inside the housing 40 to complete the maintenance. The operation process is simple and quick, effectively reducing maintenance difficulty and operating costs.

[0044] It should be noted that the lawnmower body 10 is equipped with a main board 14, and the transfer board is electrically connected to the main board 14 of the lawnmower body 10 to provide power to the main board 14 and ensure the operation of the main board 14.

[0045] In the prior art, different battery packs 20 have different shapes and sizes, while the battery compartment 11 has a fixed size and uniform fixing method. Direct installation of different battery packs 20 may result in them not being able to be correctly placed into the battery compartment 11 or becoming loose after installation. Therefore, in this application, the housing box 40 is provided with a receiving cavity 41 for accommodating different battery packs 20 and a first opening 42 for the battery packs 20 to enter and exit the receiving cavity 41, so that the same housing box 40 can be compatible with multiple battery packs 20. At the same time, the overall external dimensions of the housing box 40 remain uniform, achieving standardized matching with the battery compartment 11 on the lawnmower body 10, thereby ensuring the universality and consistency of mechanical installation. The transfer PCB board 30 is pre-installed in the receiving cavity 41. By replacing the housing box 40 module with different built-in battery packs 20 and transfer PCB, the lawnmower can adapt to new battery pack types or update communication protocols without changing the main body structure, demonstrating good expandability and technological continuity. For example Figures 1 to 5 For one type of battery pack 20, and Figure 7 For a battery pack of another shape 20.

[0046] To accommodate the installation of different battery packs 20, the battery compartment 11 has a second opening 12 for the housing 40 to enter and exit. The lawnmower body 10 is connected to a movable door 13 that opens or closes the second opening 12. After the housing 40 is inserted into the battery compartment 11, the first opening 42 and the second opening 12 are located on the same side of the lawnmower body 10, which helps to unify the operation direction and improve the human-machine interaction. The end of the receiving cavity 41 away from the first opening 42 is provided with a mounting base 43 that abuts against the battery pack 20. The mounting base 43 and the receiving cavity 41 are fixedly connected. After the movable door 13 is closed, it abuts against the battery pack 20, thereby limiting the battery pack 20 and enabling it to be bidirectionally limited within the housing 40. This minimizes the risk of loosening due to vibration or impact during operation, improving the overall reliability of the connection. Furthermore, there is no need to provide a separate cover or sealing structure for the first opening 42 of the housing 40; the sealing function can be achieved solely through the movable door 13 of the battery compartment 11. Users only need to operate one movable door 13 to complete the entire battery module installation or replacement process, enhancing user convenience.

[0047] It should be noted that the battery compartment 11 is located at the rear of the lawnmower body 10, and a second opening 12 is provided at the rear of the battery compartment 11. Users can access the battery pack 20 by crouching behind the lawnmower body 10 without leaning over it. The battery pack 20 can be pushed and pulled horizontally without bending over, which is not only convenient but also less strenuous than lifting the battery pack 20 vertically, and prevents the battery pack 20 from slipping and damaging the connecting structure. To improve sealing and waterproofing performance, a sealing ring can be provided at the edge of the movable door 13, and the first opening 42 or the second opening 12 has a sealing surface that abuts against the sealing ring.

[0048] Specifically, the mounting base 43 includes an outward protrusion 431 and a body portion 432 connected to the outward protrusion 431. The outward protrusion 431 protrudes from the body portion 432 in the direction toward the first opening 42 to form a step portion between the outward protrusion 431 and the body portion 432. The battery pack 20 is provided with a protruding positioning portion 21, which abuts against the step portion to achieve quick alignment and stable installation of the battery pack 20. At the same time, the transfer PCB board 30 is disposed on the outward protrusion 431, making it closer to the battery electrodes and effectively shortening the electrical connection path.

[0049] It should be noted that the protrusion 431 is located above the battery pack 20, and the positioning part 21 protrudes from the top of the battery pack 20.

[0050] The positioning section 21 is equipped with a power transmission end 211, and the stepped section has a power receiving end 433 that contacts the power transmission end 211. The other end of the power receiving end 433 is electrically connected to the transfer PCB board 30. The positioning section 21 not only serves to limit the axial movement of the battery pack 20, but its power transmission end 211 also forms a stable contact with the power receiving end 433 on the stepped section, thereby establishing a reliable electrical connection. During the process of inserting the battery pack 20 into the housing box 40, mechanical positioning and electrical connection can be completed simultaneously without additional operations, significantly simplifying the installation process and improving the ease of use and operational efficiency of the equipment.

[0051] It should be noted that the other end of the power connector 433 is connected to the transfer PCB board 30 via a wire harness.

[0052] In traditional designs, some battery packs 20 require physical plugging and unplugging to trigger the system wake-up mechanism. If the plugging and unplugging force is too great or the operation is inconvenient, it can easily cause user problems. Therefore, in this application, the connector includes a lead wire 50 electrically connected to the transfer PCB board 30, and a no-connection wire 51 is provided inside the battery compartment 11. The lead wire 50 and the no-connection wire 51 are equipped with no-connection terminals that are mutually pluggable. These no-connection terminals typically adopt a standardized pluggable interface design, with their plugging and unplugging force rationally set, making operation easy and providing a clear feel. Compared to directly plugging and unplugging the battery pack 20 itself, this design offers lower operational difficulty and greater ease of use. When installing or replacing the housing box 40 module, users only need to connect or disconnect the no-connection terminals to establish or disconnect the electrical connection, eliminating the need to repeatedly plug and unplug the entire battery pack 20, thereby effectively reducing operational intensity and improving the human-machine interaction experience.

[0053] It should be noted that the power transmission end 211 and the power receiving end 433 of the battery pack 20 are provided with more than three interfaces, including the battery pack positive terminal, temperature detection, battery pack grounding port, cell voltage, and empty pin interfaces. The power transmission end 211 of the battery pack 20 is connected to the relay PCB board 30 through the power receiving end 433. The relay PCB board 30 converts the charging protocol of the battery pack 20 into a compatible protocol. The relay board has multiple interfaces, including the power positive terminal, power button interface, power negative terminal, communication line, ground, and power negative terminal. It is connected to the main board 14 through the lead wire 50 and the empty wire 51 to realize the power supply to the main board 14 and ensure the normal operation of the main board 14.

[0054] To facilitate wiring, a wiring gap 45 is provided between the top end face 434 of the protrusion 431 and the inner wall of the battery compartment 11, providing a reasonable wiring channel for the lead wire 50 or connecting lines, effectively avoiding exposed cables or interference with other components, and improving the neatness and safety of the overall wiring. Meanwhile, the top end face 434 of the protrusion 431 has a protrusion 435, within which is a receiving groove 436. The transit PCB board 30 is integrated into the receiving groove 436 formed by the protrusion 435, realizing a spatial nesting layout of functional components, which helps to reduce the overall size of the module and improve the compactness of the overall structure. This receiving groove 436 not only provides good enclosure and restraint for the transit PCB board 30, but also buffers external vibrations and impacts to a certain extent, preventing displacement or damage to the transit PCB board 30 as much as possible, thereby enhancing the structural stability and operational reliability of the transit PCB board 30 under complex working conditions.

[0055] Furthermore, the housing 40 is provided with wiring holes 46 for the lead wires 50 to pass through, and the connection position of the unused wire 51 and the lead wire 50 corresponds to the position of the wiring hole 46. By rationally arranging the position of the wiring hole 46 and aligning it with the connection position of the unused wire 51 and the lead wire 50, the lead wire 50 can be guided to pass through the housing 40 in an orderly manner, forming a simple and fixed wiring path with the unused wire 51 in the battery compartment 11. This design helps to ensure accurate alignment and connection between the lead wire 50 and the unused wire 51, minimizing insertion and removal difficulties or poor contact caused by positional deviations, thereby improving assembly efficiency and the stability of electrical connections.

[0056] Furthermore, the lead wire 50 passes through the gap between the battery pack 20 and the housing 40 to exit the wiring hole 46. The battery pack 20, installed in the housing 40, abuts against the lead wire 50 to press the lead wire 50 firmly onto the housing 40. After the battery pack 20 is installed in the housing 40, its outer wall contacts and applies pressure to the lead wire 50, pressing the lead wire 50 firmly against the inside or side wall of the housing 40, forming a self-locking fixing structure. This design effectively constrains the lead wire 50 without the need for additional clips, straps, or other cable fixing devices. This not only simplifies the structure of the housing 40 but also significantly improves the stability and reliability of the lead wire 50, effectively preventing loosening or detachment due to vibration or insertion / removal operations during use, thereby ensuring the continuity and safety of the electrical connection.

[0057] It should be noted that the wiring hole 46 is located on the side wall of the housing 40 away from the first opening 42.

[0058] During the installation or removal of the battery pack 20, the protrusion 431 may cause some structural interference to the operation. Therefore, in this application, an operational gap 44 is provided between the protrusion 431 and the first opening 42 for the user to place and remove the battery pack 20, effectively avoiding this interference and improving operational smoothness. This operational gap 44 provides space for the user to insert their fingers or use auxiliary tools, facilitating the placement and removal of the battery pack 20 and significantly improving the convenience of module replacement and the human-computer interaction experience. At the same time, while meeting operational requirements, this design maintains the structural integrity of the protrusion 431, allowing it to continue to perform the functions of installing, positioning, and supporting the transfer PCB board 30, thus achieving a reasonable balance between functionality and structural strength.

[0059] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
