[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] Please refer to Figure 1 , Figure 1 A schematic diagram of the top module external structure and mechanical equipment provided in an embodiment of the present application.

[0042] like Figure 1As shown, the top module external structure 100 provided in the embodiment of the present application can be arranged on the top of the mechanical equipment, as an option, Figure 1 The mechanical equipment in the embodiment is a lawn mower. In addition, the top module external structure 100 can also be arranged on other mechanical equipment, including but not limited to a lawn mower, a garden equipment.

[0043] Please continue to refer to Figure 1 And refer to Figures 2 to 4 ,in, Figure 2 A schematic diagram of a communication module provided in an embodiment of the present application, Figure 3 A schematic diagram of a module installation slot provided in an embodiment of the present application, Figure 4 A schematic diagram of a module outer sealing plate provided in an embodiment of the present application.

[0044] The mechanical equipment includes a shell 10 and a top module external structure 100. As for the top module external structure 100, the top module external structure 100 mainly includes a communication module 1 and a module mounting slot 2 for being set on the mechanical equipment shell 10. The module mounting slot 2 is open upward and an open cavity 21 is formed inside. A module outer sealing plate 3 is installed at the opening position of the module mounting slot 2. A module connection hole 22 is provided at the bottom of the open cavity 21. The communication module 1 is vertically installed in the open cavity 21 and is plugged and fixed with the module interface 20 in the module connection hole 22.

[0045] The opening cavity 21 is located inside the housing 10 , and is connected to the outside of the housing 10 at the opening position. Therefore, when the module outer sealing plate 3 is removed, the opening is exposed to the housing 10 , making it easy to install the communication module 1 into the opening cavity 21 .

[0046] In some cases, the module installation slot 2 can be integrated into the housing 10 of the mechanical equipment, and the module outer sealing plate 3 is detachable.

[0047] In some cases, the communication module 1 includes a baseband chip and a transceiver. The baseband chip is responsible for processing the signals and data of wireless communication, such as encoding / decoding, modulation / demodulation, and data processing, while the transceiver is responsible for the transmission and reception of wireless signals, such as converting the digital signals processed by the baseband chip into radio frequency signals for transmission, and converting the received radio frequency signals back into digital signals. The two work together to ensure that the device can efficiently perform wireless communication.

[0048] The innovation of this technical solution lies in its top module external structure 100, which provides a solution to the maintenance and stability problems of the communication module 1 encountered by the smart lawn mower in the prior art. In the traditional design, the communication module 1 is built into the machine, which not only makes the replacement and upgrade of the module 1 complicated and time-consuming, but also easily leads to unstable connection due to the vibration of the machine on uneven terrain. In order to overcome these defects, this solution proposes a new module installation method.

[0049] The design of the top module external structure 100 allows the communication module 1 to be inserted from the top through an upwardly open module installation slot 2. This design simplifies the installation and removal process of the module 1, and the user can quickly operate without opening the entire mechanical device housing 10. The opening position of the module installation slot 2 is equipped with a module outer sealing plate 3, which not only protects the module 1 from damage by environmental factors, but also enhances the stability of the module 1 in the module installation slot 2. The module connection hole 22 is set at the bottom of the opening cavity 21 to ensure that the communication module 1 can be stably connected to the interface of the mechanical device housing 10. In addition, the vertical installation method of the communication module 1 utilizes the gravity of the module 1 itself, further improving the contact stability with the interface 20, and maintaining the firmness of the connection even if vibration is encountered during the operation of the machine.

[0050] Combined with the above structure and process description, it can be seen that the mechanical equipment has at least the following beneficial effects: the top module external structure 100 realizes the rapid installation and replacement of the communication module 1, effectively solving the problems of poor accessibility and replaceability caused by the built-in module 1 in the prior art, while enhancing the installation stability of the communication module 1 and the communication stability of the equipment under complex terrain.

[0051] In some cases, the module interface 20 is a USB (Universal Serial Bus) interface, and the communication module 1 is a 4G (Fourth-Generation Long Term Evolution) module.

[0052] This configuration provides a fast and stable 4G communication solution for the communication needs of the smart lawn mower. Through the design of the top module external structure 100, the 4G module can be easily connected to the control system of the smart lawn mower.

[0053] The USB interface is used as a module interface 20, which is located in the control system of the smart lawn mower and provides a standard connection point for communicating with the 4G module. The 4G module is used as a communication module 1 and is connected to the USB interface. This design simplifies the installation and replacement process of the communication module 1. The user can directly insert and fix the 4G module from the top through the opening 21 of the module installation slot 2 without opening the entire machine housing. The module outer sealing plate 3 covers the opening position of the module installation slot 2 to protect the 4G module from the external environment.

[0054] In some embodiments, the communication module 1 includes a connected module body 11 and a plug port 12 for plugging and fixing with the module interface 20. The module body 11 is provided with an anti-foolproof portion 13. The anti-foolproof portion 13 is used to limit the installation direction of the communication module 1 when it is installed in the module installation slot 2, thereby avoiding installation errors of the communication module 1 by physical blocking.

[0055] In this embodiment, the communication module 1 is designed to include a module body 11 and a plug port 12. The module body 11 is the core part of the communication module 1 and is responsible for realizing the communication function. The plug port 12 is used to be plugged and fixed with the module interface 20 to ensure that the communication module 1 can stably establish a connection with the control system of the smart lawn mower.

[0056] In addition, a foolproof portion 13 is specially designed on the module body 11. The main function of the foolproof portion 13 is to prevent the communication module 1 from being in the wrong direction or not being properly plugged in during the installation process. By setting specific structural features on the module body 11, it is ensured that the communication module 1 can be inserted into the module installation slot 2 in the correct direction and position, thereby achieving accurate and reliable plugging.

[0057] In some embodiments, the module body 11 is provided with an identification portion, which is used to indicate the installation direction of the communication module 1 when it is installed in the module installation slot 2, so as to avoid installation errors of the communication module 1 in the form of marking reminders.

[0058] In this embodiment, the identification portion is used to provide visual or tactile instructions to help the user correctly identify the installation direction and position of the communication module 1. The identification portion may include but is not limited to color markings, shape indications or text descriptions, which ensure that the user can quickly and accurately operate when installing the communication module 1, reducing the possibility of installation errors.

[0059] Whether it is the foolproof part 13 or the identification part, these designs significantly improve the installation convenience and accuracy of the communication module 1, reduce communication failures caused by improper installation, and also improve the maintenance efficiency and reliability of the entire smart lawn mower. Through the setting of the foolproof part 13 and the identification part, even non-professionals can easily install and replace the communication module 1, further improving the user experience.

[0060] In some embodiments, a limiting portion 23 is disposed inside the module installation slot 2 , and the limiting portion 23 is protruded toward the communication module 1 .

[0061] In this embodiment, the limiting portion 23 can be regarded as a protrusion on the inner wall or other position of the module installation slot 2, such as a rib, a protruding block, etc., which is not limited here. The function of the limiting portion 23 is not unique. For example, on the one hand, the limiting portion 23 can provide a guiding role, which guides the communication module 1 to be inserted into the module installation slot 2 along the correct path; on the other hand, the limiting portion 23 provides necessary support after the communication module 1 is installed in place.

[0062] As an option, the guiding design of the limiter 23 ensures the precise alignment of the communication module 1 during the insertion process, reducing the risk of damage or unstable connection caused by improper insertion angle. The support design of the limiter 23 provides additional stability and support for the communication module 1, helps maintain the position of the communication module 1 in the module installation slot 2, and prevents the module from shifting or falling off due to vibration or impact.

[0063] In some embodiments, the communication module 1 is provided with an anti-foolproofing portion 13 ; the limiting portion 23 cooperates with the anti-foolproofing portion 13 .

[0064] In this embodiment, the limiting portion 23 also has a fool-proof design.

[0065] The design of the communication module 1 introduces a foolproofing portion 13, which is an important error-proofing mechanism to ensure the accuracy and reliability of the communication module 1 during installation. The foolproofing portion 13 usually has a unique shape or structural features that cooperate with the limit portion 23 inside the module installation slot 2. The foolproofing portion 13 ensures that the communication module 1 can only be inserted into the module installation slot 2 in the correct direction and position. This matching mechanism prevents the module from being inserted in reverse or tilted, thereby avoiding installation errors and improving the accuracy of the installation process.

[0066] Optionally, when the communication module 1 is correctly aligned and inserted into the module installation slot 2, the interaction between the foolproof portion 13 and the limit portion 23 provides a stable lock, ensuring that the module is fixed in position in the installation slot and is not easily displaced due to external vibration or impact. This locking effect not only ensures a stable connection between the communication module 1 and the module interface 20, but also protects the module from the risk of accidental falling off or damage.

[0067] In some embodiments, there are multiple limiting portions 23 , and the multiple limiting portions 23 are arranged at intervals along the circumference of the communication module 1 .

[0068] In this embodiment, this design provides more uniform and comprehensive support, ensuring that the communication module 1 is stably fixed in the module installation slot 2. The presence of multiple limit portions 23 not only enhances the positioning accuracy of the module, but also helps to disperse any force that may act on the module, reducing the risk of damage caused by excessive local force.

[0069] In addition, the limiting parts 23 arranged at intervals along the circumference can more effectively guide the communication module 1 to be correctly inserted into the module installation slot 2, and each limiting part 23 plays a guiding role to ensure that the module slides smoothly into the installation slot along the preset path. This circumferential arrangement also helps to evenly distribute the supporting force after the communication module 1 is installed in place, preventing the module from tilting or shifting due to uneven force.

[0070] Through this design, the number and layout of the limiting parts 23 work together to improve the installation efficiency and stability of the communication module 1, and also enhance the reliability and durability of the smart lawn mower in actual use. This uniformly distributed limiting part 23 design is one of the key factors to ensure the fast, accurate and stable installation of the communication module 1.

[0071] In some embodiments, the limiting portion 23 extends from the opening position of the module mounting slot 2 to the bottom position of the module mounting slot 2, and the limiting portion 23 includes a gradual limiting portion 231, and the gradual limiting portion 231 is configured as the gradual limiting portion 231 with a gradually protruding thickness in its extension direction.

[0072] In this embodiment, the design of the limiting portion 23 has specific directionality and structural characteristics. The limiting portion 23 starts from the opening position of the module installation slot 2 and extends to the bottom position of the module installation slot 2. This arrangement enables the limiting portion 23 to provide continuous guidance and support for the communication module 1 during the entire insertion process.

[0073] Among them, the limiting portion 23 adopts a gradual design of protruding thickness in the extension direction, which is called the gradual limiting portion 231. This gradual design makes the protruding part of the limiting portion 23 gradually increase in thickness from the opening position to the bottom position. Such a structure not only provides an initial loose guide for the communication module 1 to facilitate the insertion of the module, but also as the module goes deeper into the installation slot, the gradual limiting portion 231 gradually provides a tighter fit to ensure the correct position and stability of the module in the installation slot.

[0074] The design of the gradual limiter 231 also helps prevent the communication module 1 from tilting or shifting during the insertion process, ensuring that the module can smoothly and accurately reach the predetermined position. At the same time, this gradual structure enhances the locking effect after the module is installed, so that the communication module 1 is more firmly fixed in the module installation slot 2, effectively resisting displacement caused by vibration or impact.

[0075] Please refer to Figure 5 and Figure 6 , Figure 5 for Figure 2 The foolproof schematic diagram of the communication module in Figure 6 for Figure 3 Schematic diagram of the module installation slot.

[0076] In some embodiments, the fool-proof portion 13 includes an upper protrusion 131 located on the front of the communication module and a lower protrusion 132 located on the back of the communication module, and the gradual limit portion 231 cooperates with the upper protrusion 131 to achieve that when the upper protrusion 131 faces the gradual limit portion 231, the upper protrusion 131 cooperates with the gradual limit portion 231 and the communication module 1 is loaded into the module mounting slot 2, and when the lower protrusion 132 faces the gradual limit portion 231, the lower protrusion 132 is blocked by the gradual limit portion 231 and the communication module 1 cannot be loaded into the module mounting slot 2.

[0077] In this embodiment, the foolproof portion 13 is further defined. The foolproof portion 13 is composed of two parts: an upper protrusion 131 and a lower protrusion 132. The upper protrusion 131 is located at the front end of the communication module 1, and the lower protrusion 132 is located at the back end of the communication module 1. This design ensures the directionality of the communication module 1 when it is inserted into the module installation slot 2, and prevents the possibility of reverse insertion.

[0078] In this embodiment, the stopper 23 includes a gradual stopper 231, which cooperates with the upper protrusion 131. The design of the gradual stopper 231 allows the upper protrusion 131 to smoothly cooperate with it when facing it, which indicates that the communication module 1 is being inserted into the module installation slot 2 in the correct direction. When the upper protrusion 131 cooperates with the gradual stopper 231 correctly, the communication module 1 can be smoothly installed in the module installation slot 2.

[0079] On the contrary, when the lower protrusion 132 of the communication module 1 faces the gradual limit portion 231, the lower protrusion 132 will be blocked by the gradual limit portion 231, preventing the communication module 1 from being further inserted. This blocking mechanism ensures that the communication module 1 will not be installed in the module installation slot 2 in the wrong direction, thereby avoiding incorrect installation.

[0080] Through this ingenious foolproof design, the installation process of the communication module 1 becomes more intuitive and user-friendly. When installing the communication module 1, the user can simply determine whether the module is correctly aligned by observing the interaction between the upper convex portion 131 and the lower convex portion 132 and the gradual limit portion 231. This design significantly improves the accuracy of installation, reduces the possibility of installation errors, and also improves the reliability and stability of the entire smart lawn mower system.

[0081] In some embodiments, the top module external structure 100 further includes a sealing member disposed between the opening position of the module mounting slot 2 and the module outer sealing plate 3 .

[0082] In this embodiment, the design of the top module external structure 100 takes into account the possible impact of environmental factors on the communication module 1, and in particular, a seal is added between the opening of the module installation slot 2 and the module outer sealing plate 3. The seal is designed to provide additional protection to prevent dust, moisture and other external factors that may damage the communication module 1 from entering the module installation slot 2.

[0083] The opening position of the module installation slot 2 is specially designed with a sealing installation portion 24, which provides a specific position for fixing and installing the sealing member. The sealing member can be a sealing ring, and the sealing installation portion 24 can be in the form of a ring groove. This design facilitates the installation of the sealing ring. The sealing ring is installed in the ring groove of the sealing installation portion 24. When the module outer sealing plate 3 covers the opening position of the module installation slot 2, the sealing ring can be in close contact with the module outer sealing plate 3 and the edge of the module installation slot 2 to form a sealed environment. Such a sealing design not only protects the communication module 1 from environmental factors, but also helps to maintain the electrical performance and mechanical stability of the module 1.

[0084] In some embodiments, the module outer sealing plate 3 is provided with a protrusion 31 protruding in a direction away from the opening position of the module installation slot 2 .

[0085] In this embodiment, the design of the module outer sealing plate 3 specifically introduces a raised portion 31, which is located in the direction away from the opening of the module installation slot 2. The module outer sealing plate 3 can be regarded as a dome plate. The addition of the raised portion 31 provides the module outer sealing plate 3 with additional functions and advantages.

[0086] First, the ridge 31 enhances the mechanical strength of the module outer sealing plate 3, making it more resistant to external impact and pressure, thereby protecting the internal communication module 1 from damage. Second, the design of the ridge 31 may also help improve the sealing performance of the module outer sealing plate 3, and cooperate with the seal to more effectively isolate dust and moisture, ensuring that the communication module 1 can work stably even in harsh environments.

[0087] In addition, the presence of the raised portion 31 provides a convenient gripping point for the operator, making the operation easier and safer during installation, removal or maintenance, which is particularly important in application scenarios where the communication module 1 needs to be frequently replaced or maintained.

[0088] At the same time, the raised portion 31 may also have a diversion function, for example, it can guide air circulation to help dissipate heat, or guide water flow to prevent moisture from accumulating on the surface of the module outer sealing plate 3, further improving the durability and reliability of the smart lawn mower.

[0089] Please refer to Figure 7 , Figure 7A schematic diagram of an upper cover plate provided in an embodiment of the present application.

[0090] In some embodiments, the mechanical device further includes an upper cover plate 30 , which is mounted on the top of the housing 10 , and the upper cover plate 30 is located above the module mounting slot 2 .

[0091] In this embodiment, the upper cover plate 30 can cover the outer shell 10 so that the module installation slot 2 is located below the upper cover plate 30, thereby further preventing moisture from entering the module installation slot 2 and improving the waterproof performance of the top module external structure 100.

[0092] In a specific embodiment, the mechanical device provided in the present application includes a shell 10, and the top of the shell 10 is provided with the above-mentioned top module external structure 100. The mechanical device also includes a main control board located inside the shell 10, and the main control board is provided with a module interface 20. The main control board is located near the top of the mechanical device, and the module interface 20 passes through the module connection hole 22 in the top module external structure 100. Because the communication module 1 is plugged and fixed with the module interface 20, the communication module 1 can be connected to the main control board without setting a wiring harness.

[0093] The mechanical device should have all the beneficial effects of the above-mentioned top module external structure 100, which will not be described in detail here.

[0094] In some embodiments, the mechanical device is a lawn mowing robot.
