Description

Technical Field

[0001] This utility model belongs to the field of lawnmower technology, and specifically relates to a lawnmower. Background Technology

[0002] Current smart lawnmowers widely employ vision sensors or cameras to identify lawn boundaries, obstacles, and plan optimal mowing paths to improve efficiency and automation. As key components, these vision sensors / cameras generate considerable heat during operation. If this heat is not dissipated effectively and promptly, it will negatively impact the normal operation of the equipment. Existing heat dissipation solutions often fail to meet the demands of long-term stable operation of smart lawnmowers, potentially leading to overheating, reduced operating time, or even triggering automatic shutdown protection mechanisms, severely affecting the lawnmower's efficiency and user experience. Therefore, designing a more effective heat dissipation structure to ensure that vision sensors / cameras maintain suitable operating temperatures under various conditions has become a pressing technical challenge. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a lawnmower that solves the problem that existing heat dissipation solutions often cannot meet the needs of intelligent lawnmowers for long-term stable operation, which may eventually lead to the equipment shortening its working time due to overheating, or even triggering the automatic shutdown protection mechanism, seriously affecting the efficiency of lawnmower use and user experience.

[0004] To achieve the above-mentioned objectives and other related objectives, this utility model proposes a lawnmower, comprising:

[0005] chassis;

[0006] A camera module, mounted on the housing, comprises:

[0007] A heat dissipation metal frame, which is fixedly mounted on the housing;

[0008] The camera module is fixedly mounted on the heat dissipation metal frame;

[0009] A housing, which covers the heat dissipation metal frame and the camera module and is connected to the housing;

[0010] A heat dissipation space is formed inside the cover, and the heat dissipation metal frame is at least partially located in the heat dissipation space. The heat dissipation space is provided with an air inlet and an air outlet. The air inlet is located on the cover, and the air outlet is located on the housing or the cover to form a heat dissipation air duct.

[0011] In one embodiment of the present invention, the camera module includes a camera and a metal housing wrapped around the camera, the metal housing being fixedly connected to the heat dissipation metal frame.

[0012] In one embodiment of this utility model, a mounting surface is formed on the heat dissipation metal frame, and the metal shell is mounted on the mounting surface.

[0013] In one embodiment of this utility model, the heat dissipation metal frame is provided with a plurality of heat dissipation fins, which are located on the path of the heat dissipation air duct.

[0014] In one embodiment of this utility model, the cover, the heat dissipation metal frame, and the housing enclose the heat dissipation space, the air inlet is disposed on the cover and located below the camera module, and the air outlet is disposed on the housing.

[0015] In one embodiment of this utility model, the heat dissipation fins are located below the mounting surface.

[0016] In one embodiment of this utility model, the air inlet is disposed on the housing and located above the camera module, and the air outlet is disposed on the top or side surface of the housing.

[0017] In one embodiment of this utility model, the air outlet is disposed on the cover and located on the side away from the camera module.

[0018] In one embodiment of the present invention, the heat dissipation fins are disposed on the top surface of the heat dissipation metal frame and extend along the direction from the air inlet toward the air outlet.

[0019] In one embodiment of the present invention, a control circuit board is further included. The control circuit board is located inside the housing and is fixedly connected to the bottom surface of the heat dissipation metal frame.

[0020] This utility model provides a lawnmower with a highly efficient heat dissipation structure, particularly addressing the heat dissipation problem of the camera module through a systematic optimization design. By setting up a heat dissipation space enclosed by a heat dissipation metal frame, a cover, and a housing, combined with a heat dissipation air duct formed by the air inlet and outlet, the thermal management capability of the camera module in complex outdoor environments is effectively improved. It has the following beneficial effects:

[0021] This invention employs a heat-dissipating metal frame as the core heat-conducting component, providing not only stable support for the camera module but also excellent heat conduction and dissipation functions. The camera module has an external metal casing, which is installed in surface contact with the heat-dissipating metal frame, significantly improving heat transfer efficiency. Furthermore, multiple heat-dissipating fins are further incorporated into the heat-dissipating metal frame, greatly increasing the heat exchange area and enhancing heat exchange efficiency during airflow.

[0022] This invention, through the rational arrangement of the air inlet and outlet positions, allows cooling air to flow along a predetermined path through key heat-generating areas, forming an efficient airflow circulation. Depending on the application scenario, the air inlet can be placed above or below the camera module, and the air outlet can be placed at a corresponding position on the cover or housing to achieve the optimal heat dissipation path. The heat dissipation fins extend along the airflow direction, further guiding the airflow and improving the overall heat dissipation capacity.

[0023] This invention also fixes the control circuit board to the bottom of the heat dissipation metal frame, realizing dual synchronous heat dissipation for the control circuit board and the camera module. Without adding any additional structure, it fully leverages the functional integration advantages of the heat dissipation metal frame and improves the operational stability of the entire system.

[0030] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0031] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0032] Please see Figures 1 to 3 As shown, this utility model provides a lawnmower, which includes a housing 10 and a camera module 40 mounted on the housing 10. The camera module 40 is used for functions such as identifying lawn boundaries, obstacles, and assisting in path planning, and generates a certain amount of heat during operation. To effectively solve the problem of poor heat dissipation of camera modules in the prior art, this utility model achieves efficient cooling of the camera module by setting up a structural component with heat dissipation function. Specifically, the camera module 40 includes a heat dissipation metal frame 42, a camera module, and a cover 44. The heat dissipation metal frame 42 is made of a metal material with good thermal conductivity, such as aluminum alloy or copper alloy, and is fixedly mounted on the housing 10. The heat dissipation metal frame 42 not only serves as a supporting structure for the camera module, but also has good heat conduction and dissipation functions, which can quickly absorb and conduct away the heat generated by the camera module during operation. The camera module is fixedly mounted on the heat dissipation metal frame 42, and can be stably installed by means of screw connection, snap-fit ​​structure, or adhesive. The camera module can be an existing high-definition wide-angle camera or other visual sensors with image acquisition function to meet the environmental recognition requirements of the intelligent lawnmower. The cover 44 is installed outside the heat dissipation metal frame 42 and the camera module, and is connected to the housing 10 to form a closed or semi-closed protective space. The cover 44 is preferably made of plastic or composite material with strong weather resistance and a certain heat insulation capacity, which can prevent dust, rain and other impurities from entering, and also provide structural protection for the internal components.

[0033] Please see Figure 2 and Figure 3As shown, in this embodiment, a heat dissipation space 45 is formed within the housing 44, and the heat dissipation metal frame 42 is at least partially located within this heat dissipation space 45 to facilitate heat conduction and dissipation. Further, the heat dissipation space 45 is correspondingly provided with an air inlet 46 and an air outlet 47, wherein: the air inlet 46 is located on the housing 44; the air outlet 47 can be located on the housing 44 or the casing 10, preferably at the bottom of the casing 10 or at a position away from the air inlet 46, to form a reasonable airflow path. Through the above structural design, the air inlet 46 and the air outlet 47 form a heat dissipation duct penetrating the heat dissipation space 45. When the lawnmower is in operation, due to overall movement or the action of the built-in fan, external air enters the heat dissipation space 45 from the air inlet 46, flows over the surface of the heat dissipation metal frame 42, thereby carrying away the heat conducted from it, and finally exits from the air outlet 47, completing the entire heat dissipation cycle.

[0034] To further improve heat dissipation efficiency, guide ribs or heat dissipation fins can be added within the heat dissipation space 45 to enhance airflow speed and heat exchange efficiency. Simultaneously, a dust filter can be installed at the air inlet 46 to prevent dust from entering and affecting the normal operation of the camera module. It is understood that this invention effectively improves the heat dissipation performance of the camera module by setting up a heat dissipation space 45 formed by the cooperation of the heat dissipation metal frame 42 and the cover 44 within the camera module 40, and constructing a heat dissipation airflow channel through the air inlet 46 and the air outlet 47. This structure is not only simple and easy to assemble, but also significantly improves the stability and service life of the camera module in complex environments such as high temperature and dust, thereby ensuring the reliability and intelligent level of the lawnmower during long-term operation.

[0035] Please see Figure 2 and Figure 3As shown, in this embodiment, the cover 44 is detachably connected to the housing 10 to facilitate quick inspection, cleaning, or replacement of the camera module and its related heat dissipation components. Specifically, the cover 44 is detachably fixed to the housing 10 through snap-fit ​​structures, screw connections, sliding plug-ins, or magnetic structures. This connection method ensures that the cover 44 provides effective protection for the camera module while also allowing users or technicians to quickly disassemble the cover 44 when needed to inspect internal components, clean dust, or replace damaged parts. Since lawnmowers operate in complex outdoor environments for extended periods, the camera module and its heat dissipation structure are susceptible to dust, rainwater, grass clippings, and other impurities, which may lead to decreased heat dissipation efficiency or even abnormal image recognition functionality. With the detachable cover 44, it can be periodically opened for cleaning and maintenance, ensuring the camera module is always in good working order. Furthermore, in the event of a collision or accidental damage, this detachable structure facilitates the individual replacement of the damaged housing 44 or the repair of internal components without requiring the complete replacement of the camera module or lawnmower body, thereby reducing maintenance costs and improving the maintainability of the equipment. It is understood that by designing the housing 44 and the casing 10 as detachably connected, this invention significantly improves the maintainability and ease of replacement of the camera module components without sacrificing protective performance, which is beneficial for extending the service life of the equipment, improving the user experience, and enhancing after-sales maintenance efficiency.

[0036] Please see Figure 2 and Figure 3 As shown, in this embodiment, the camera module includes a camera and a metal casing 49 enclosing the camera. The metal casing 49 is fixedly connected to a heat dissipation metal frame 42 to achieve a more efficient heat conduction path. The camera is a visual sensor component with image acquisition capabilities, and can be a high-definition wide-angle lens or other camera device suitable for outdoor environment recognition. The metal casing 49 is preferably made of aluminum alloy or copper alloy with good thermal conductivity, tightly enclosing the camera, not only providing structural protection but also effectively absorbing and conducting the heat generated during camera operation. The metal casing 49 is securely connected to the heat dissipation metal frame 42 by screws, clips, or welding, allowing the heat generated by the camera to be conducted sequentially through the metal casing 49 to the heat dissipation metal frame 42, and then from the heat dissipation metal frame 42 to the heat dissipation space 45 inside the housing 44, thereby achieving efficient heat dissipation. This structural design significantly enhances the heat conduction efficiency between the camera module and the heat dissipation metal frame 42, avoiding problems such as image distortion, system misjudgment, or equipment shutdown due to localized overheating, and improving the stability and reliability of the camera module under high-temperature, long-term operating conditions.

[0037] In addition, a thermal pad or thermal adhesive can be placed between the metal casing 49 and the heat dissipation metal frame 42 to further reduce contact thermal resistance and improve overall heat dissipation performance.

[0038] It is understandable that by setting a metal casing 49 on the outside of the camera and fixing it to the heat dissipation metal frame 42, this utility model realizes the rapid conduction and effective dissipation of heat from the camera module, improves the operational stability of the camera module under complex working conditions, and further ensures the long-term reliable operation of the lawnmower intelligent recognition system.

[0039] Please see Figure 2 and Figure 3 As shown, in this embodiment, a mounting surface 421 is formed on the heat dissipation metal frame 42, and the metal shell 49 is mounted on the mounting surface 421 to achieve a large-area surface contact between the two, thereby significantly improving heat conduction efficiency. The mounting surface 421 is a flat surface on the heat dissipation metal frame 42 that has been processed, preferably formed by mechanical milling, grinding, or precision machining after casting, to ensure that it has good flatness and smoothness so as to achieve a tight fit with the metal shell 49. The mounting surface 421 can be located on the top, side, or multiple directions of the heat dissipation metal frame 42, and can be flexibly arranged according to the installation position of the camera module. By fixing the metal shell 49 to the mounting surface 421 of the heat dissipation metal frame 42, the contact area between the metal shell 49 and the heat dissipation metal frame 42 is significantly increased, and heat can be conducted more evenly and quickly from the metal shell 49 to the heat dissipation metal frame 42, avoiding heat accumulation due to poor local contact, which would affect the normal operation of the camera. Furthermore, to further enhance thermal conductivity, thermal grease can be applied between the metal casing 49 and the mounting surface 421, thermal pads can be installed, or a press-fit structure can be used to reduce interfacial thermal resistance and improve overall heat dissipation efficiency. This structural design not only improves the heat absorption capacity of the heat dissipation metal frame 42 for the camera module, but also enhances the overall structural stability of the camera module, which helps extend the service life of the camera and improves the reliability of the lawnmower during long-term operation in high-temperature environments.

[0040] It is understood that by setting a mounting surface 421 on the heat dissipation metal frame 42 and mounting the metal shell 49 on the mounting surface 421, this utility model achieves a large-area contact between the metal shell and the heat dissipation metal frame, effectively improving the heat conduction efficiency and further ensuring the stable operation of the camera module under complex working conditions.

[0041] Please see Figure 2 and Figure 3As shown, in this embodiment, the structure of the heat dissipation metal frame is further optimized. The heat dissipation metal frame is provided with multiple heat dissipation fins 422, which are located along the heat dissipation airflow path formed between the cover 44 and the housing 10 to enhance the heat exchange efficiency during air convection. The heat dissipation fins 422 are preferably integrally formed or welded to the heat dissipation metal frame, and their shape can be flat, wavy, or perforated, depending on the actual airflow direction and spatial layout. The heat dissipation fins 422 are arranged along the extension direction of the heat dissipation airflow, allowing the cooling air passing through this area to fully contact the fin surface, thereby accelerating heat dissipation.

[0042] When the lawnmower operates, it generates airflow (such as through its own movement driving external airflow, or in conjunction with a built-in fan). Air enters the heat dissipation space 45 inside the housing 44 through the air inlet 46, then flows sequentially over the camera module, the metal casing 49, and the surface of the heat dissipation metal frame. It further passes through the gaps between the heat dissipation fins 422, carrying away a significant amount of heat transferred to the fins, and finally exits through the air outlet 47, completing an efficient heat dissipation cycle. By setting multiple heat dissipation fins 422, the effective heat exchange area of ​​the heat dissipation metal frame is significantly increased. Simultaneously, the gaps between the fins guide airflow and increase flow velocity, thereby greatly improving overall heat dissipation efficiency. Even in high-temperature, high-humidity, or dusty outdoor environments, the camera module can operate stably, avoiding problems such as image blurring, recognition failure, or equipment shutdown due to overheating. It is understood that by setting multiple heat dissipation fins 422 on the heat dissipation metal frame and arranging them in the path of the heat dissipation air duct, this invention effectively enhances the heat dissipation capacity of the camera module, improves the operational stability and reliability of the lawnmower in complex environments, and has good engineering application prospects.

[0043] Please see Figure 2 and Figure 3 As shown, in one specific embodiment, the cover 44, the heat dissipation metal frame, and the housing 10 enclose a heat dissipation space 45. This heat dissipation space 45 provides a closed or semi-closed heat exchange environment for the camera module and its heat dissipation components, which is beneficial for guiding airflow and enhancing the effective dissipation of heat. The air inlet 46 is disposed on the cover 44, preferably located below the camera module, allowing external cold air to enter the heat dissipation space 45 from the bottom and flow upward along the camera module and the heat dissipation metal frame, thereby achieving a bottom-up natural convection or forced convection heat dissipation path. The air outlet 47 is disposed on the housing 10, preferably located on the side of the housing 10 away from the air inlet 46 or at the bottom, to form a heat dissipation air duct that runs through the entire heat dissipation space 45. This arrangement of air inlets and outlets not only helps to improve the airflow speed but also effectively avoids the accumulation of hot air in local areas, thereby improving the overall heat dissipation efficiency.

[0044] Furthermore, the heat dissipation fins 422 are located below the mounting surface 421, specifically within the airflow channel between the camera module and the air inlet 46. This arrangement ensures that cooling air, upon entering the heat dissipation space 45, first passes through the area where the heat dissipation fins 422 are located, thereby maximizing the heat exchange capacity of the fins and rapidly removing heat. Because the heat dissipation fins 422 are close to the air inlet 46 and located below the mounting surface 421, they not only effectively absorb heat conducted from the metal casing 49 to the heat dissipation metal frame, but also achieve efficient cooling with the help of the incoming low-temperature airflow, further improving the synergistic efficiency of heat conduction and dissipation.

[0045] Furthermore, this structural design facilitates enhanced airflow during lawnmower operation through airflow disturbances generated by its own movement or in conjunction with the built-in fan, resulting in more thorough heat exchange within the cooling duct and ensuring the temperature stability of the camera module during prolonged operation. It is understood that this embodiment, by enclosing the housing 44, the heat dissipation metal frame, and the casing 10 to form a heat dissipation space 45, and by placing the air inlet 46 below the camera module and the air outlet 47 on the casing 10, combined with the rational layout of the heat dissipation fins 422 located below the mounting surface 421, achieves optimized control of the airflow path and a significant improvement in heat dissipation efficiency. This effectively solves the overheating problem caused by poor heat dissipation in the camera module in existing technologies, improving the stability and reliability of the lawnmower in complex environments.

[0046] In another embodiment, an optimized heat dissipation structure for the camera module suitable for different operating conditions is proposed. The air inlet is located on the housing 44 above the camera module, and the air outlet is also located on the housing 44, preferably on the side away from the camera module. The air outlet is located on the top or side surface of the housing 44, preferably on the side opposite the air inlet 46, to ensure that the airflow can fully cover the entire heat dissipation space 45 before being discharged, thus improving heat exchange efficiency. More preferably, the air outlet is located on the side away from the camera module, so that the cooling air, after entering, can first pass through the camera module and its metal casing 49 before flowing to the air outlet, thereby achieving priority cooling of key heat-generating components. The heat dissipation fins 422 are located on the top surface of the heat dissipation metal frame and extend along the direction from the air inlet to the air outlet. This fin arrangement helps guide the airflow along the fin surface, increasing the contact area and contact time between the air and the fins, thereby significantly improving heat transfer efficiency.

[0047] Specifically, the heat dissipation fins 422 can be linear, wavy, or have a channeled structure, extending in the same direction as the airflow. This enhances airflow flow and prevents heat retention caused by local eddies. With this design, even without an additional fan, good heat dissipation can be achieved through natural convection or airflow disturbances generated by the movement of a lawnmower. Furthermore, to further improve the rationality of airflow organization, a dust filter can be installed at the air inlet 46, and a one-way exhaust valve or louver structure can be installed at the air outlet 47 to prevent external impurities from flowing back into the heat dissipation space 45 while ensuring smooth airflow discharge. It is understood that by placing the air inlet 46 above the housing 44, the air outlet 47 on the side away from the camera module, and extending the heat dissipation fins 422 along the airflow direction on the top of the heat dissipation metal frame, this invention achieves a rational optimization of the heat dissipation duct. This not only improves heat dissipation efficiency but also enhances the system's adaptability to the external environment, significantly improving the working stability and service life of the camera module under complex operating conditions.

[0048] Please see Figure 2 and Figure 3 As shown, in this embodiment, the overall thermal management structure of the lawnmower is further optimized. Specifically, the lawnmower also includes a control circuit board 60, which is located inside the housing 10 and fixedly connected to the bottom surface of the heat dissipation metal frame to achieve synchronous heat dissipation of multiple heat-generating components through the same heat dissipation structure. The control circuit board 60 is the core control unit of the lawnmower, responsible for image processing, path planning, motor drive, and other functions, and generates a certain amount of heat during operation. In traditional structures, the control circuit board 60 is usually installed independently inside the housing 10, lacking effective heat dissipation methods, which can easily lead to system instability or shortened lifespan due to excessively high local temperatures. This utility model fixes the control circuit board 60 to the bottom surface of the heat dissipation metal frame, allowing the heat generated to be directly conducted to the heat dissipation metal frame, and then dissipated to the external environment through the heat dissipation fins 422 and the heat dissipation duct. Since the heat dissipation metal frame itself has good thermal conductivity, it can simultaneously undertake the heat dissipation tasks of the camera module and the control circuit board 60, achieving the design goal of multi-purpose material and integrated structure. Specifically, the control circuit board 60 can be tightly fixed to the bottom surface of the heat sink metal frame using screws, thermally conductive adhesive, or thermally conductive pads to ensure good thermal contact between the two. If necessary, thermally conductive grease can be applied to its contact interface or a pressing structure can be set to further reduce contact thermal resistance and improve heat transfer efficiency.

[0049] This structural design not only simplifies the layout of the overall heat dissipation system and reduces the use of additional heat dissipation components, but also effectively improves the overall thermal management capability of the lawnmower. It is particularly suitable for intelligent lawnmowers with limited space and high power consumption, ensuring high-performance operation while enhancing the stability and reliability of the equipment in high-temperature environments. It is understood that by fixing the control circuit board 60 to the bottom surface of the heat dissipation metal frame, this invention achieves a collaborative heat dissipation structure design for the control circuit board and the camera module, fully utilizing the thermal conductivity of the heat dissipation metal frame to improve the lawnmower's adaptability and long-term operational stability in complex working environments.

[0050] In summary, this invention significantly improves the heat dissipation of the lawnmower camera module in complex outdoor environments by creating a heat dissipation space enclosed by a heat-dissipating metal frame, a cover, and a housing, combined with a rationally arranged air inlet and outlet to form an efficient heat dissipation airflow. Simultaneously, the heat-dissipating metal frame serves both as support and a heat conductor, further enhancing heat conduction efficiency and heat exchange capacity in conjunction with the metal housing and heat dissipation fins, effectively preventing image recognition anomalies or equipment shutdowns due to overheating. Furthermore, the fixed connection between the control circuit board and the heat-dissipating metal frame enables coordinated heat dissipation of multiple components, while the detachable structure of the cover and housing improves the system's maintainability and practicality. The overall solution is compact, provides stable heat dissipation, and is highly adaptable, solving the technical problem of poor heat dissipation in existing camera modules and demonstrating promising application prospects.
