[0035] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings, i.e., embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] Please refer to Figure 7The utility model proposes a mowing device 100 and an automatic mower. The mowing device 100 can be easily installed on a self-moving device 200. The self-moving device 200 generates a predetermined mowing path based on the mowing area set by the user. The self-moving device 200 can be a mobile carrier such as a crawler vehicle or a wheeled vehicle that can have a mowing device 100 installation position 22. The self-moving device 200 and the mowing device 100 are combined to form an automatic mower to complete the automatic mowing work; the mowing device 100 is used to complete the mowing operation of the predetermined area along the predetermined path generated by the self-moving device 200 under the drive of the self-moving device 200.

[0038] The tooth comb 20 of the mowing device 100 is used to prevent foreign objects such as stones and branches from entering the cutting area of ​​the mowing device 100, and to comb the uneven lawn. The tooth comb 20 in the prior art is installed on the housing 40 of the device, and the housing 40 is usually made of plastic. When the tooth comb 20 collides with the lawn, the plastic housing 40 and the components attached to the housing 40 are easily damaged by the force of the tooth comb 20, affecting the service life and appearance integrity of the device. Based on this, the applicant conducted in-depth research to solve the technical problem that the housing 40 of the mowing device 100 is easily damaged due to collision, so as to form the technical solution of the present application.

[0039] The structure of the lawn mowing device 100 in the present application is described in detail below.

[0040] Please refer to Figure 2 The utility model proposes a lawn mowing device 100, including a main frame 10 and a tooth comb 20. The main frame 10 is used to carry at least one component among a blade disc assembly 60, a blade disc lifting assembly 70, and a supporting wheel assembly 80; the tooth comb 20 is located at the front end of the lawn mowing device 100 and installed below the main frame 10.

[0041] The main frame 10 is the supporting structure of the whole device, and is usually made of rigid materials to ensure that the main frame 10 has sufficient strength to bear the equipment components such as the cutter disc assembly 60, the cutter disc lifting assembly 70, and the supporting wheel assembly 80. In this embodiment, the cutter disc lifting assembly 70 is located at the upper part of the main frame 10, and the main frame 10 has sufficient hollow space, so that the cutter disc assembly 60 connected to the cutter disc lifting assembly 70 is placed at the bottom of the main frame 10 through the hollow space, and the cutter disc assembly 60 is driven by the cutter disc lifting assembly 70 to adjust the upper and lower positions in the hollow space; the supporting wheel assembly 80 can be installed at the front end of the main frame 10, and the supporting wheel assembly 80 is located at the bottom of the mowing equipment 100 to help the mowing equipment 100 move smoothly on the lawn.

[0042] The tooth comb 20 is located at the front end of the mowing device 100, that is, the part that first contacts the lawn, and is installed below the main frame 10. The function of the tooth comb 20 is to prevent foreign objects such as stones and branches from entering the cutting area of ​​the mowing device 100, and at the same time comb the uneven grass so that it enters the cutting area more neatly, which is conducive to improving the overall mowing effect. In the related art, the tooth comb 20 is directly installed on the shell 40, and the shell 40 is easily damaged. The tooth comb 20 of this embodiment is directly installed on the main frame 10 and is relatively independent of the shell 40. Therefore, the shell 40 will not be directly affected by the force generated by the collision of the tooth comb 20. In contrast, this installation method avoids the damage to the shell 40 caused by the collision of the tooth comb 20 with the ground, which not only improves the durability of the mowing device 100, but also helps to reduce maintenance costs and repair frequency.

[0043] Please refer to Figure 2 and Figure 3 In some embodiments, the main frame 10 is further provided with a frame extension 30 extending downward, and the tooth comb 20 is mounted on the frame extension 30. In this way, on the one hand, the front end of the main frame 10 has a certain downward extension amount, and the height of the tooth comb 20 above the ground can be controlled by setting the height of the frame extension 30; on the other hand, the frame extension 30 and the main frame 10 form an integral structure, which increases the stability and carrying capacity of the device. When the tooth comb 20 collides, the frame extension 30 can disperse the impact force and protect the key components inside the main frame 10 from external impact.

[0044] Please refer to Figure 5 In some embodiments, the frame extension 30 includes a support 31 and a cross frame 32. One end of the support 31 is connected to the main frame 10, and the other end is connected to the cross frame 32. The tooth comb 20 is installed on the cross frame 32. The fixed height of the support 31 is designed to ensure that the distance between the tooth comb 20 and the ground is within a suitable range and can adapt to the height of most lawns; at the same time, the cross frame 32 is designed to be the same shape as the front end of the main frame 10 to ensure that it can adapt to the shell 40 of the main frame 10.

[0045] In some embodiments, a plurality of pillars 31 are provided, and the plurality of pillars 31 are symmetrically distributed about the symmetry axis of the main frame 10 .

[0046] In this embodiment, the frame extension 30 of the mowing device 100 is designed with a layout of multiple pillars 31. The arrangement of multiple pillars 31 can disperse the force of the tooth comb 20 on the main frame 10 from multiple points, which is beneficial to the stability of the mowing device 100. The pillars 31 are symmetrically distributed about the symmetry axis of the main frame 10 to ensure the balance of the mowing device 100 during operation.

[0047] Please refer to Figure 5In some embodiments, the main frame 10 has a crossbeam 11 for mounting the supporting wheel set 80 .

[0048] The crossbeam 11 has mounting positions 22 for mounting the supporting wheel set 80, which are symmetrically distributed at both ends of the crossbeam 11. The crossbeam 11 can be specifically arranged at the front position of the main frame 10, so that the overall weight distribution of the mowing device 100 is balanced. Figure 2 and Figure 6 In some embodiments, the tooth comb 20 has a guide portion 21 that is inclined from the outside to the inside, so as to guide the mowing device 100 to be lifted up along the slope when overcoming obstacles.

[0049] The tooth comb 20 of the mowing device 100 is designed with a guide part 21 that is inclined from outside to inside. Its function is to enable the mowing device 100 to smoothly cross the obstacle without directly colliding with the tooth comb 20 when the mowing device 100 encounters highly uneven terrain or obstacles. When the mowing device 100 travels to highly uneven terrain or obstacles, the front end of the guide part 21 of the tooth comb 20 first contacts the ground or obstacles, and the driving force of the mowing device 100 guides the mowing device 100 to smoothly lift up when crossing the obstacle with the inwardly inclined guide part 21, thereby avoiding direct collision with the obstacle. In this way, the collision between the mowing device 100 and the ground or obstacles is reduced to a certain extent, which is conducive to protecting the various components of the mowing device 100 including the housing 40 and extending the service life; at the same time, the setting of the guide part 21 is conducive to the mowing device 100 smoothly crossing obstacles in complex terrain, thereby improving the adaptability of the mowing device 100.

[0050] Please refer to Figure 1 and Figure 4 In some embodiments, the mowing device 100 further includes a shell 40 , which covers the main frame 10 and the frame extension 30 , and a hollow portion 41 of the bottom of the shell 40 is exposed where the frame extension 30 and the tooth comb 20 are connected.

[0051] It should be noted that the shell 40 includes an upper shell covering the main frame 10 and a bottom shell located below the main frame 10. The upper shell and the bottom shell are combined to form an internal space to accommodate the main frame 10 and various components attached to the main frame 10. The hollow portion 41 is set at the bottom of the shell 40, that is, the above-mentioned bottom shell. The tooth comb 20 is fixedly connected to the frame extension body 30 inside the shell 40 through the hollow portion 41 at the bottom of the shell 40. In this way, compared with the design in which the tooth comb 20 is connected to the bottom of the shell 40, the shell 40 is prevented from being directly damaged by the tooth comb 20. At the same time, the shell 40 has the effect of preventing weeds, dust, and rainwater from entering the interior, providing good protection for the functional components inside the mowing device 100.

[0052] Please refer to Figure 6In some embodiments, a mounting position 22 mounted on the frame extension body 30 is provided on the upper portion of the tooth comb 20, and a protrusion 221 is provided in the middle portion of the mounting position 22. The protrusion 221 passes through the outer shell 40 through the hollow portion 41 and is connected to the bottom of the frame extension body 30. The protrusion 221 is surrounded by a recess 222 for placing a waterproof rubber ring.

[0053] The mounting position 22 on the upper part of the tooth comb 20 has a protrusion 221 and a recess 222, wherein the protrusion 221 is used to pass through the outer shell 40 through the hollow portion 41 of the outer shell 40, thereby connecting with the frame extension body 30 inside the outer shell 40. The advantage of such assembly is that the hollow portion 41 provides a channel for the protrusion 221 to be directly connected to the frame extension body 30. When the tooth comb 20 collides, the force generated by the collision will not be directly transmitted to the outer shell 40, but will act on the main frame 10 through the frame extension body 30, effectively avoiding damage to the outer shell 40; the recess 222 around the protrusion 221 is provided with a waterproof rubber ring, so that the waterproof rubber ring is located between the outer shell 40 and the tooth comb 20, which is conducive to preventing rainwater from entering the interior of the mowing equipment 100.

[0054] Please refer to Figure 1 In some embodiments, the outer shell 40 is also provided with an anti-collision device 50 at its periphery, and the mowing device 100 changes its original traveling direction to avoid the obstacle after the anti-collision device 50 contacts the obstacle.

[0055] An anti-collision device 50 is designed around the outer shell 40 of the mowing equipment 100. The device is located at the front end of the outer shell 40 and can contact obstacles first. When the mowing equipment 100 is moving, the anti-collision device 50 contacts an obstacle and triggers a mechanism to stop moving or change the direction of movement, so that the mowing equipment 100 can avoid obstacles in time and avoid collisions. The anti-collision device 50 further prevents damage to the internal and external components of the mowing equipment 100, and in particular can prevent damage to the outer shell 40 caused by collisions with obstacles. Specifically, the anti-collision device 50 can be made of rubber or elastic material, and absorbs the force through compression and deformation to reduce the impact on the inside of the mowing equipment 100 and the outer shell 40.

[0056] The present invention further provides an automatic lawn mower, comprising a self-moving device 200 and the above-mentioned lawn mowing device 100; the lawn mowing device 100 is arranged on the self-moving device 200, and can complete the lawn mowing operation in a preset area under the drive of the self-moving device 200.

[0057] The self-moving device 200 is a mobile vehicle body that can adopt a variety of designs, such as a tracked vehicle, a wheeled vehicle, etc., and can move freely under different terrains and environmental conditions. The self-moving device 200 has precise positioning technology, such as a global positioning system and an inertial navigation system, so that the self-moving device 200 can be accurately positioned. The self-moving device 200 can also be equipped with other obstacle avoidance systems in addition to the anti-collision device 50, such as ultrasonic obstacle avoidance, visual obstacle avoidance, infrared obstacle avoidance, etc., which can avoid obstacles during operation and move according to a preset path. The self-moving device 200 is equipped with the mowing device 100 described in the above embodiment, which can efficiently clean the lawn in the designated area under the drive of the self-moving device 200, and the entire cleaning process does not require manual operation. It has the ability to independently complete the mowing task, reduces manpower input, and enables the mowing task to be completed quickly and efficiently in different scenarios.
