Description

Technical Field

[0001] This utility model relates to the field of lawn mowing robot technology, and in particular to an emergency stop button assembly and a lawn mowing robot. Background Technology

[0002] In actual production, to ensure the emergency stop button can reset smoothly, a certain amount of space must be allowed during manufacturing and assembly to guarantee smooth button operation. When a user attempts to activate the emergency stop button by pressing its edge or corner, the button may tilt because the force is not applied at the center. This tilt not only affects the user experience but may also cause the button to become stuck, unable to respond immediately, thus failing to achieve the intended instant stop function.

[0003] In existing technical solutions, a single balancing structure is typically used to control the balance of the emergency stop button. This approach has the following drawbacks:

[0004] 1. Unique direction of balanced force: Because it relies on balanced force in only one direction, when the user presses the button from different angles or positions, it is still easy to cause the button to tilt or get stuck, thus failing to respond in time.

[0005] 2. The balance structure is prone to detachment: A single balance structure is prone to detachment after prolonged use or when subjected to external impact, causing its balancing effect to fail and further affecting the normal function of the button. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides an emergency stop button assembly and a lawn mowing robot to solve the technical problems of insufficient stability and reliability of traditional emergency stop buttons in related technologies.

[0007] This utility model provides an emergency stop button assembly, including: a base and a button, wherein the base has a mounting opening, and the button is movably mounted at the mounting opening along the depth direction of the mounting opening; the emergency stop button assembly further includes:

[0008] The first balancing structure includes a first support base and a first balancing rod. The first support base is disposed at the mounting port, and the first balancing rod passes through the first support base with a gap and is connected to the button at an upward inclination in a first direction, so that the first balancing rod rotates in conjunction with the button when the button is pressed, thereby limiting the tilt of the button in the first direction.

[0009] The second balancing structure includes a second support base and a second balance bar. The second support base is disposed at the mounting port, and the second balance bar passes through the second support base with a gap and is connected to the button in an upward tilt along the second direction, so that when the button is pressed, the second balance bar rotates in conjunction with the button to limit the tilt of the button in the second direction.

[0010] The first support base and / or the second support base are provided with an anti-detachment structure to prevent the first support base from separating from the first balance bar and / or the second support base from the second balance bar.

[0012] The limiting block is disposed at the mounting port and is used to limit the first balance bar and / or the second balance bar to the limiting port.

[0013] Furthermore, at least one side of the limiting port is provided with a support platform for supporting the first balance bar and / or the second balance bar.

[0014] Furthermore, the anti-detachment structure includes: a connected positioning port and an elastic port, the positioning port being formed in the first support base and / or the second support base, and the elastic port being elastic. When the first balance bar and / or the second balance bar are placed in the positioning port, the elastic port elastically deforms to clamp the first balance bar and / or the second balance bar at the positioning port.

[0015] Furthermore, the first support base and / or the second support base are provided with a guide portion, the width of which is gradually reduced and passes through the elastic opening.

[0037] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0038] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0039] In the embodiments of this utility model, such as Figures 1-2 As shown, the emergency stop button assembly includes: a base 1 and a button 2. The base 1 has a mounting opening 101. The button 2 is movably mounted in the mounting opening 101 along its depth direction. The emergency stop button assembly also includes: a first balancing structure 3, a second balancing structure 4, and an anti-detachment structure 5. The first balancing structure 3 includes a first support 301 and a first balance rod 302. The first support 301 is disposed in the mounting opening 101. The first balance rod 302 passes through the first support 301 and is connected to the button 2 at an upward inclination along a first direction, so that when the button 2 is pressed, the first balance rod 302 rotates in conjunction with the button 2, thereby limiting the movement of the button. Button 2 is tilted in a first direction; the second balance structure 4 includes a second support base 401 and a second balance rod 402. The second support base 401 is disposed in the mounting port 101, and the second balance rod 402 is passed through the second support base 401 with a gap and is connected to the button 2 in an upward tilt along the second direction, so that when the button 2 is pressed, the second balance rod 402 rotates in conjunction, thereby limiting the tilt of the button 2 in the second direction; wherein, the first support base 301 and / or the second support base 401 are provided with an anti-detachment structure 5, which is used to limit the separation of the first support base 301 from the first balance rod 302 and / or the second support base 401 from the second balance rod 402.

[0040] Specifically, in this embodiment of the invention, the base 1 has a mounting opening 101, and the button 2 is connected to the mounting opening 101 by a spring, so that the button 2 can be moved along the depth direction of the mounting opening 101; that is, the button 2 can be pressed down under the action of external force, compressing the spring; after the external force disappears, the elasticity of the spring will reset the button 2. The button 2 can be a magnetic Hall effect button that does not require an opening in the base 1, or other types of buttons. Since the above methods are existing technologies, they will not be described in detail here.

[0041] In this embodiment of the invention, a first balancing structure 3 is provided to prevent the button from tilting in the first direction when it is pressed down. The first balancing structure 3 is defined as having a first support base 301 and a first balancing rod 302. The first support base 301 is fixed at the mounting port 101 and the first balancing rod 302 is connected to the first support base 301, so that part of the first balancing rod 302 is installed at the first support base 301 and the other part of the first balancing rod 302 is connected to the button 2. At the same time, when the button 2 and the base 1 are relatively stationary, the first balancing rod 302 is tilted upward in the first direction. In this way, not only can the first balancing rod 302 support the button 2, but the first balancing rod 302 can also rotate in the first support base 301 during the pressing of the button 2, so that the button 2 maintains a pressing balance in the first direction, effectively avoiding friction and jamming caused by the button 2 tilting in the first direction, thereby improving its reliability. Of course, since the first balance bar 302 is connected to the button 2, the button 2 will pull the first balance bar 302 to rotate in the opposite direction during the reset process, so that it maintains its initial upward tilting posture along the first direction; in case of emergency, the button 2 can respond quickly, improving the safety of the overall system.

[0042] Similarly, in this embodiment of the invention, to prevent the button from tilting in the second direction when it is pressed down, a second balancing structure 4 is provided. The second support base 401 of the second balancing structure 4 cooperates with the second balancing rod 402 to keep the button 2 balanced in the second direction. That is, a part of the second balancing rod 402 is installed at the second support base 401, and another part of the second balancing rod 402 is connected to the button 2. When the button 2 and the base 1 are relatively stationary, the second balancing rod 402 tilts upward in the second direction. When the button 2 is pressed, the button 2 can rotate the second balancing rod 402 relative to the second support base 401, which can support the button 2 and prevent the button 2 from tilting in the second direction when pressed. Furthermore, the button 2 can be reset by pulling the second balancing rod 402 to rotate in the opposite direction to reset it.

[0043] In this embodiment, a first balancing structure 3 and a second balancing structure 4 are simultaneously provided at the mounting port 101 of the base 1. Through the synergistic effect of the first balancing structure 3 and the second balancing structure 4, the tilting of the button 2 in multiple directions can be effectively limited, ensuring that the button 2 remains balanced when subjected to force at any angle, avoiding jamming and tilting, and improving the response speed and reliability of the button 2. Of course, in order to balance the force on the first balancing rod 302 and the second balancing rod 402 respectively and prevent them from tilting during rotation, the first support base 301 and the second support base 401 mentioned above can be provided in multiple ways. Using multiple support bases allows the corresponding balancing rods to be subjected to force at multiple points, thereby maintaining their own balance.

[0044] In this embodiment of the utility model, both the first support base 301 and the second support base 401 are provided with an anti-detachment structure 5, which can prevent the balance bar from detaching from the support base, ensure that the balance structure can remain stable even after long-term use or when subjected to external impact, and extend the service life of the button 2.

[0045] This embodiment solves the problem of button 2 tilting and getting stuck during pressing by the synergistic effect of the two balancing structures and the continuous limiting effect of the anti-detachment structure 5, thereby improving the reliability and response speed of button 2.

[0046] In one embodiment, such as Figure 2 , Figure 4 As shown, the anti-detachment structure 5 includes a limiting opening 501 and a limiting block 502. The limiting opening 501 is formed in the first support base 301 and / or the second support base 401, and is used to accommodate the first balance bar 302 and / or the second balance bar 402. The limiting block 502 is disposed in the mounting opening 101 and is used to cover the limiting opening 501. Specifically, in order to restrict the balance bar within the corresponding support base so that it can only rotate within that support base, this embodiment defines the anti-detachment structure 5 as including the limiting opening 501 and the limiting block 502 (hereinafter, the above-mentioned anti-detachment structure 5 is disposed at the first balance structure 3; in other embodiments, the anti-detachment structure 5 may also be disposed at the second balance structure 4, or both balance structures may have it). Figure 4 As shown, a limiting port 501 is formed at the first support base 301, with its opening facing upwards, for accommodating the first balance bar 302, and allowing the first balance bar 302 to pass through the limiting port 501, serving as a mounting and positioning function; in addition, a limiting block 502 is provided at the mounting port 101. The limiting block 502 has an L-shaped structure, with one end fixed to the base 1 and the other end extending above the limiting port 501, covering the limiting port 501, thereby restricting the first balance bar 302 to the limiting port 501. When the button 2 is activated to rotate the first balance bar 302, it can prevent the first balance bar 302 from disengaging from the limiting port 501. Alternatively, the aforementioned limiting block 502 and the first support base 301 are spaced apart, that is, the limiting block 502 and the limiting opening 501 are staggered in the vertical direction, so that the limiting block 502 fits against the surface of the first balance bar 302 and limits the first balance bar 302 within the limiting opening 501, which can also prevent the first balance bar 302 from falling off.

[0047] Furthermore, in one embodiment, as Figure 4As shown, at least one side of the limiting port 501 is provided with a support platform 503 for supporting the first balance bar 302 and / or the second balance bar 402. Specifically, in order to reduce the swaying of the first balance bar 302 and to distribute the pressure evenly, this embodiment provides a support platform 503 on the side of the limiting port 501. The support platform 503 extends along the length direction of the first balance bar 302 to support the first balance bar 302, thereby providing additional support points, reducing its swaying during pressing and resetting, and ensuring that the first balance bar 302 rotates more smoothly; at the same time, it can also distribute the pressure of the button 2 when pressed more evenly, reducing the situation of excessive local force, thereby improving the stability of the entire button 2 assembly.

[0048] like Figure 2 , Figure 5 As shown, in one embodiment, the anti-detachment structure 5 includes a communicating positioning port 504 and an elastic port 505. The positioning port 504 is formed in the first support base 301 and / or the second support base 401. The elastic port 505 is elastic. When the first balance bar 302 and / or the second balance bar 402 are placed in the positioning port 504, the elastic port 505 elastically deforms to clamp the first balance bar 302 and / or the second balance bar 402 at the positioning port 504. Specifically, in order to restrict the balance bar within the corresponding support base so that it can only rotate within that support base, this embodiment defines the anti-detachment structure 5 as including the positioning port 504 and the elastic port 505 (hereinafter, the above-mentioned anti-detachment structure 5 is provided at the second balance structure 4; in other embodiments, the anti-detachment structure 5 may also be provided at the first balance structure 3, or both balance structures may have it). Figure 5 As shown, a positioning port 504 is provided at the second support base 401, which can accommodate the second balance bar 402; in addition, an elastic port 505 is also provided at the second support base 401, which extends to communicate with the positioning port 504, and the elastic port 505 has a certain elasticity, so as to use the elastic capacity of the elastic port 505 to restrict the second balance bar 402 within the positioning port 504, which can also play a role in preventing detachment.

[0049] Furthermore, in one embodiment, as Figure 5As shown, the first support base 301 and / or the second support base 401 are provided with a guide portion 506. The width of the guide portion 506 is gradually decreasing and extends through the elastic opening 505. Specifically, to facilitate the insertion of the second balance bar 402, this embodiment provides a guide portion 506 at the second support base 401. This guide portion 506 is gradually decreasing and extends to the elastic opening 505, so that the second balance bar 402 can be inserted into the positioning opening 504 along the guide portion 506 through the elastic opening 505. Of course, the gradually decreasing guide portion 506 can reduce the swaying of the second balance bar 402 in the positioning opening 504, ensuring that the second balance bar 402 is more stable when rotating.

[0050] In this embodiment, the first direction and the second direction are perpendicular to each other. This effectively prevents the button 2 from tilting in two orthogonal directions. This multi-directional balance design ensures that the button 2 remains balanced when subjected to force at any angle, avoiding the limitations that a unidirectional balance structure may have. For example, the first direction is set along the front-back direction, the second direction is set along the left-right direction, and the button 2 can be pressed up-down under the action of the spring.

[0051] In one embodiment, such as Figure 3 As shown, the button 2 is provided with a first hook 201 and a second hook 202, and the first balance bar 302 and the second balance bar 402 are respectively hooked onto the first hook 201 and the second hook 202. Specifically, in order to connect the first balance bar 302 and the second balance bar 402 to different positions of the button 2, this embodiment provides the first hook 201 and the second hook 202 at the end of the button 2 facing the mounting opening 101, so that the upwardly inclined part of the first balance bar 302 is hooked onto the first hook 201, and the upwardly inclined part of the second balance bar 402 is hooked onto the second hook 202, so that the two balance bars can rotate with the movement of the button 2. Of course, in order to prevent the balance bar from slipping off the hook, a limiting notch can be provided at the hook to limit the balance bar from slipping off the hook. At the same time, multiple hooks can be provided to maintain the force balance of the balance bar.

[0052] Furthermore, in one embodiment, as Figure 2As shown, both the first balance bar 302 and the second balance bar 402 have a U-shaped structure, with their ends inclined relative to their corresponding closed ends, and are respectively hung on the first hook 201 and the second hook 202. This embodiment not only solves the problem of button 2 easily tilting and getting stuck in traditional designs, but also significantly improves the stability, reliability, and response speed of button 2, enhancing the user's operating experience and strengthening system safety. Specifically, the U-shaped balance bar provides multi-point support, making button 2 more stable during pressing and resetting, reducing the risk of shaking and tilting; it distributes the pressure of button 2 more evenly when pressed, reducing excessive local force and improving the overall structural stability; it can respond more quickly to the pressing and resetting actions of button 2, ensuring that button 2 can quickly return to its initial position during resetting. Of course, the U-shaped balance bar allows users to press button 2 from any angle without affecting its function, improving operational convenience and user experience.

[0053] In one embodiment, such as Figure 2 As shown, the mounting port 101 is provided with a plurality of protrusions 6, and the first balance bar 302 and / or the second balance bar 402 rotate to abut or move away from the protrusions 6. Specifically, in order to limit the rotation angle of the first balance bar 302 and the second balance bar 402, this embodiment provides a plurality of protrusions 6 at the mounting port 101, with the plurality of protrusions 6 corresponding to the first balance bar 302 and the second balance bar 402, so that when the button 2 is pressed to its limit position, the balance bar abuts against the corresponding protrusion 6 to limit its continued rotation. On the other hand, one of the mounting port 101 and the button 2 is provided with a guide post 7, and the other is provided with a guide sleeve 8, with the guide post 7 slidingly extending into the guide sleeve 8. By using the guide post 7 to move linearly up and down within the guide sleeve 8, the button 2 is guided, which can further prevent it from tilting.

[0054] This embodiment also provides a lawn mowing robot, including the emergency stop button assembly described above. The specific structure of the emergency stop button assembly is the same as described in the above embodiment. Since this lawn mowing robot adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
