Description
Technical Field
[0001] This utility model relates to the field of lawnmower technology, and in particular to a lawnmower collision structure and a lawnmower. Background Technology
[0002] With rapid urbanization, the demand for green spaces in cities is increasing daily, reflected not only in the expansion of public green spaces but also in the meticulous creation of private gardens. Lawns, as a crucial component of urban greening, require particularly careful maintenance. Against this backdrop, lawnmowers, as efficient and convenient gardening tools, are seeing their application scope expand, leading to a surge in market demand. Sustained economic growth and rising living standards have resulted in more and more families pursuing aesthetically pleasing and tidy lawns, which has not only increased the adoption rate of lawnmowers but also driven technological advancements and innovations in this field.
[0003] Technological innovation has led to the electrification and intelligent transformation of lawnmowers. Electric lawnmowers, with their environmental friendliness, low noise, and ease of operation, are gradually becoming the new favorite in the market. Intelligent lawnmowers can further improve mowing efficiency and reduce manual intervention by automatically planning mowing paths through sensors and algorithms, making lawn maintenance easier and more efficient.
[0004] However, existing electric lawnmowers inevitably encounter various obstacles during actual operation, such as trees and flower bed edges. When these collisions occur, the lawnmower's impact structure deforms to absorb the impact force and protect the internal mechanical components. However, when the collision is too violent, the existing impact structure may deform excessively and directly contact the lawnmower body. This could not only damage the lawnmower's outer shell but also cause surface scratches, affecting the lawnmower's appearance and lifespan. Utility Model Content
[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a lawnmower collision structure and a lawnmower, so as to solve the problem of shell damage and surface scratches caused by the collision structure directly contacting the lawnmower body due to excessive deformation when the lawnmower collides.
[0006] To solve the above-mentioned technical problems, this utility model provides a lawnmower collision structure to provide cushioning when the lawnmower collides with an obstacle, including:
[0007] Lawn mower body;
[0008] The system includes a collision bumper and several cushioning elastic bars. One end of each cushioning elastic bar is attached to the collision bumper, and the other end is connected to the lawnmower body. The collision bumper has a limiting part, and the lawnmower body has a limiting groove that matches the limiting part. When the collision bumper collides with an obstacle, it retracts towards the lawnmower body. The cushioning elastic bars deform, and the limiting part engages with the limiting groove, thus limiting the collision bumper and preventing further impact on the lawnmower body.
[0009] As a more preferred embodiment, the bumper includes a collision housing, and the limiting portion is disposed on the collision housing.
[0010] As a more preferred approach, an opening is provided on one side of the collision housing, with the opening facing the lawnmower body, which reduces manufacturing costs and increases aesthetics.
[0011] As a more preferred approach, the collision bumper includes two or more limiting parts, and the lawnmower body is provided with two or more limiting grooves that are adapted to the limiting parts. The multiple limiting parts and corresponding multiple limiting grooves ensure that multiple areas on the lawnmower body can be protected when the collision bumper collides with an obstacle, providing more comprehensive protection.
[0012] As a more preferred approach, two or more of the limiting parts are symmetrically distributed on both sides of the collision shell. The uniform and symmetrical distribution of the limiting parts can ensure that when the limiting parts are engaged in the limiting grooves, the impact force can be evenly distributed to all areas of the lawnmower body, reducing the damage caused by the impact.
[0013] As a more preferred approach, the collision shell is provided with several reinforcing ribs, which ensure the strength of the collision shell while being inexpensive.
[0014] As a more preferred embodiment, the lawnmower collision structure also includes a magnetic component and a Hall element, which are respectively disposed at relative positions on the collision bumper and the lawnmower body. When the collision bumper collides with an obstacle, the collision bumper retracts towards the lawnmower body, the relative positions of the magnetic component and the Hall element change, and the lawnmower body further determines the current operating status of the lawnmower based on the voltage change in the Hall element and takes appropriate action.
[0015] As a more preferred approach, a buffer structure is provided within the limiting groove. This buffer structure can further provide cushioning and reduce the impact force when the limiting part is about to collide with the limiting groove.
[0016] As a more preferred approach, the buffer structure includes multiple flexible ridges, which are directly disposed on the buffer structure and are easy to install.
[0017] To solve the above problems, this utility model also provides a lawnmower, including: the above-mentioned lawnmower collision structure.
[0018] As described above, the lawnmower collision structure and lawnmower of this utility model have the following beneficial effects: When the lawnmower collision structure of this utility model is in use, the collision bumper collides with an obstacle, and the collision bumper retracts towards the lawnmower body. At the same time, the buffer elastic rod deforms and the limiting part is inserted into the limiting groove, thus limiting the collision bumper and preventing further impact on the lawnmower body. It also avoids direct contact between the collision bumper and the lawnmower body, preventing damage and scratches to the lawnmower body. Moreover, through the deformation of the buffer elastic rod, most of the impact force during the collision is buffered, reducing the damage to the lawnmower.
[0019] The lawnmower of this utility model uses the above-mentioned lawnmower collision structure to deal with collisions during operation. Through the deformation of the buffer elastic rod, most of the impact force during the collision is buffered; and by using the limiting part and the limiting groove, direct contact between the collision bumper and the lawnmower body is avoided, as well as damage and scratches to the lawnmower body.
[0020] The lawnmower collision structure and lawnmower of this utility model, through the setting of buffer elastic rod, limiting part and limiting groove, buffer most of the impact force during the collision, avoid damage and scratches to the lawnmower body, and solve the problem of shell damage and surface scratches caused by excessive deformation of the collision structure directly contacting the lawnmower body when the lawnmower collides.

[0041] like Figures 1 to 3 As shown, this utility model provides a lawnmower collision structure to provide cushioning when the lawnmower collides with an obstacle, including:
[0042] Lawn mower body 1;
[0043] The system includes a collision bumper 2 and several buffer elastic rods 3. One end of each buffer elastic rod 3 is mounted on the collision bumper 2, and the other end is connected to the lawnmower body 1. The collision bumper 2 has a limiting part 21, and the lawnmower body 1 has a limiting groove 11 that matches the limiting part 21. When the collision bumper 2 collides with an obstacle, it retracts towards the lawnmower body 1. The buffer elastic rods 3 deform, and the limiting part 21 engages with the limiting groove 11. The collision bumper 2 is thus limited, preventing further impact on the lawnmower body 1.
[0044] To better illustrate the collision structure of this utility model for a lawnmower, the following specific application will be used as an example: When the collision structure of this utility model collides with an obstacle, the collision bumper 2 retracts towards the lawnmower body 1. Simultaneously, the buffer elastic rod 3 deforms, and the limiting part 21 engages with the limiting groove 11. The collision bumper 2 is thus limited, preventing further impact on the lawnmower body 1. This also avoids direct contact between the collision bumper 2 and the lawnmower body 1, preventing damage and scratches to the lawnmower body 1. Furthermore, the deformation of the buffer elastic rod 3 buffers most of the impact force during the collision, reducing damage to the lawnmower.
[0045] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 3 As shown, the collision bumper 2 is located at the lower front side of the lawnmower body 1 to protect the lawnmower from the front when it collides with an obstacle during its forward movement.
[0046] In some possible embodiments of this utility model, such as Figure 2 As shown, the collision bumper 2 includes a collision housing 22, and the limiting part 21 is disposed on the collision housing 22; furthermore, the limiting part 21 and the collision housing 22 are manufactured by an integral molding process.
[0047] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 2 As shown, the buffer elastic rod 3 includes an elastic connecting rod 31 and fixed seats 32 disposed at both ends of the elastic connecting rod 31. The buffer elastic rod 3 is connected to the collision bumper 2 and the lawnmower body 1 respectively through the fixed seats 32 at both ends. More specifically, in this embodiment, the elastic connecting rod 31 is vertically arranged. When the collision bumper 2 collides with an obstacle, the elastic connecting rod 31 deforms toward the lawnmower body 1. More specifically, in this embodiment, the lawnmower collision structure includes four buffer elastic rods 3 to provide sufficient buffering capacity.
[0048] In some possible embodiments of this utility model, such as Figure 2 As shown, an opening is provided on one side of the collision housing 22, which faces the lawnmower body 1, reducing manufacturing costs and increasing aesthetics; furthermore, the closed side of the collision housing 22 faces the direction of the lawnmower's movement and adopts a streamlined design to reduce wind resistance when the lawnmower is moving.
[0049] In some possible embodiments of this utility model, such as Figure 2 As shown, the collision bumper 2 includes two or more limiting parts 21, and the lawnmower body 1 is provided with two or more limiting grooves 11 that are adapted to the limiting parts 21. The multiple limiting parts 21 and the corresponding multiple limiting grooves 11 ensure that multiple areas on the lawnmower body 1 can be protected when the collision bumper 2 collides with an obstacle, making the protection more comprehensive.
[0050] In some possible embodiments of this utility model, such as Figure 2 As shown, two or more limiting parts 21 are symmetrically distributed on both sides of the collision housing 22. The uniform and symmetrical distribution of the limiting parts 21 can ensure that when the limiting part 21 is inserted into the limiting groove 11, the impact force can be evenly distributed to all areas of the lawnmower body 1, reducing the damage caused by the impact.
[0051] In some possible embodiments of this utility model, such as Figure 2As shown, the collision shell 22 is provided with a plurality of reinforcing rib structures 221 inside. The reinforcing rib structures 221 ensure the strength of the collision shell 22, while being inexpensive.
[0052] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 3 As shown, the lawnmower collision structure also includes a magnetic component 231 and a Hall element, which are respectively disposed at the relative positions of the collision bumper 2 and the lawnmower body 1. When the collision bumper 2 collides with an obstacle, the collision bumper 2 retracts towards the lawnmower body 1, and the relative position of the magnetic component 231 and the Hall element changes. The lawnmower body 1 further determines the current operating status of the lawnmower based on the voltage change in the Hall element and takes corresponding actions. Furthermore, in this embodiment, two protrusions 23 are symmetrically arranged on both sides of the collision housing 22. The protrusions 23, the collision housing 22, and the limiting part 21 are all designed with... Manufactured using a one-piece molding process, the magnetic component 231 comprises two parts, which are disposed on the protrusion 23. Two Hall elements are disposed at corresponding positions on the lawnmower body 1. The lawnmower can determine which side of the collision housing 22 collided when the collision occurred based on the different Hall voltages of the two Hall elements, and then implement different response strategies. More specifically, in this embodiment, the Hall elements are disposed inside the lawnmower body 1, and obtain the current collision information by sensing, avoiding the wired connection of traditional sensors, improving the airtightness of the lawnmower body 1, thereby improving the stability and service life of the lawnmower.
[0053] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 3 As shown, a buffer structure is provided in the limiting groove 11. The buffer structure can further provide buffering and reduce the impact force when the limiting part 21 is about to collide with the limiting groove 11.
[0054] In some possible embodiments of this utility model, such as Figure 1 as well as Figure 3 As shown, the buffer structure includes multiple flexible ridges 111, which are directly disposed on the buffer structure and are easy to install.
[0055] This utility model also provides a lawnmower, including: the above-mentioned lawnmower collision structure.
[0056] To better illustrate the lawnmower of this utility model, the following specific application will be used as an example: The lawnmower of this utility model uses the aforementioned lawnmower collision structure to cope with collisions during operation.

Furthermore, the limiting part 21 and the limiting groove 11 prevent direct contact between the collision bumper 2 and the lawnmower body 1, as well as damage and scratches to the lawnmower body 1. It can be seen that the lawnmower collision structure and lawnmower of this utility model, through the setting of the buffer elastic rod 3, the limiting part 21, and the limiting groove 11, buffer most of the impact force during the collision, preventing damage and scratches to the lawnmower body 1. This solves the problem in the prior art where, during a collision, the collision structure directly contacts the lawnmower body 1 due to excessive deformation, causing damage to the outer shell and surface scratches.
[0057] In summary, this utility model has the following advantages:
[0058] 1. Effective cushioning: The design of the collision bumper 2 and the buffer elastic bar 3 effectively absorbs the impact force during a collision, protecting the lawnmower body 1.
[0059] 2. Preventing damage: The cooperation between the limiting part 21 and the limiting groove 11 prevents the collision bumper 2 from directly contacting the lawnmower body 1, thus avoiding damage and scratches.
[0060] 3. Structural stability: The design of multiple limiting parts 21 and limiting grooves 11 provides comprehensive protection, disperses impact force, and reduces damage.
[0061] 4. Symmetrical distribution: The symmetrically arranged limiting parts 21 ensure the uniform distribution of impact force and improve the stability of the structure.
[0062] 5. Reinforcing Rib Structure 221: The reinforcing rib structure 221 inside the impact shell 22 enhances the strength of the shell while maintaining low cost.
[0063] 6. Magnetic component 231 and Hall element: Provides a non-contact collision detection method, improving the sealing and service life of the lawnmower.
[0064] 7. Streamlined design: The streamlined design of the collision shell 22 reduces wind resistance during lawnmower movement and improves efficiency.

[0067] 10. Comprehensive protection: The placement and design of the collision bumper 2 protects the lawnmower from the front, improving safety.
[0068] This patented lawnmower collision structure, through its innovative design, provides an effective collision protection mechanism. The combined use of the collision bumper 2 and the buffer elastic rod 3 not only absorbs the impact force during a collision but also, through the design of the limiting part 21 and the limiting groove 11, avoids direct contact with the lawnmower body 1, thus protecting the lawnmower body 1 from damage and scratches. The symmetrically distributed limiting part 21 and the reinforcing rib structure 221 enhance the overall stability and strength. The application of the magnetic component 231 and Hall element provides a non-contact collision detection method, improving the lawnmower's airtightness and service life.
