Description

Technical Field

[0001] The present invention relates to the field of garden tools, in particular to a power switch and an automatic walking device. Background Art

[0002] Autonomous vehicles, such as smart lawn mowers, require a power switch to turn the main power supply on and off. Existing power switches typically use a key. By inserting the key into a key-slotted mounting socket, turning the key toggles the switch inside the mounting socket, turning the power on or off.

[0003] During transportation of autonomous vehicles, the power switch must remain off. Conventional keys, when rotated to the off position, cannot secure the key in place within the mounting base. Consequently, conventional autonomous vehicles are prone to dropping or losing keys during transportation. Similarly, with this type of key-activated system, after the autonomous vehicle is finished operating and the power switch is turned off, the user must remove the key, which can also easily lead to key loss.

[0004] The invention patent with patent number US9218924 discloses a switch key structure, which includes three rotation positions: LIVE, OFF and STORAGE. When the key is in the STORAGE position, the key can be fixed in the keyhole and not fall out, while keeping the power off. However, since the STORAGE position is located between the LIVE position and the OFF position in this patent, the key rotates in the same direction when it turns from the OFF position to the LIVE position and the STORAGE position, so it can only be distinguished by the user's feel or by observing the rotation angle of the key. It is difficult for the user to clearly distinguish the boundary between the LIVE position and the STORAGE position. Therefore, it is easy for the user to rotate the key that should be rotated to the STORAGE position to the LIVE position, or to rotate the key that should be rotated to the LIVE position to the STORAGE position. This power switch is easy to be misoperated by the user and trigger the automatic walking device to turn on in inappropriate circumstances, posing a safety hazard. Summary of the Invention

[0023] Beneficial effects

[0024] The present invention provides a keyway on the inner wall of the mounting base, which can guide the key through the keyway, so that when the key is rotated to the open position in the keyway, the automatic driving device is triggered to open, and when the key is rotated to the storage position, the automatic driving device is kept closed.

DETAILED DESCRIPTION

[0043] To make the purpose and technical solutions of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Those skilled in the art will understand that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art in the art to which this invention belongs. It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with their meanings in the context of the prior art and, unless defined as such, will not be interpreted in an idealized or overly formal sense.

[0045] The meaning of "and / or" in the present invention means that both situations where each exists alone or both exist at the same time are included.

[0046] The meaning of "inside" and "outside" in the present invention refers to the direction pointing to the inside of the power switch or the automatic walking device itself, and the opposite direction is outside; it is not a specific limitation on the device mechanism of the present invention.

[0047] The meaning of "top end and bottom end" mentioned in the present invention refers to that when the user is facing the automatic walking device, the end pointing from the keyhole to the internal electrical switch is the bottom end, and the opposite is the top end, and it is not a specific limitation on the device mechanism of the present invention.

[0048] The term “connection” as used in the present invention may refer to a direct connection between components or an indirect connection between components via other components.

[0049] To address the problem of blurred boundaries between different positions of the power switch of existing automatic walking equipment due to the same rotation direction of the open position and the storage position, the present invention uses a keyway structure to set the open position and the storage position in two directions respectively, so that the rotation direction of each position when the switch is used can be clearly defined, avoiding user misoperation.

[0050] Figure 1 The power switch for autonomous vehicles such as lawn mower robots according to the present invention comprises a key 1 and a keyhole 2 disposed at the top of a mounting base 4. For ease of illustration, the mounting base 4 is schematically illustrated in the accompanying drawings; its actual shape may vary depending on the housing design of the autonomous vehicle. An electrical switch 7 is located within the keyhole 2, located at the bottom of the mounting base. The key 1 is inserted into the keyhole 2 and, by turning or pushing, the electrical switch 7 is turned on and off, thereby turning the power switch on and off.

[0051] In order to fix the key inserted into the keyhole, a key slot 201 is provided on the inner wall of the mounting base, which includes an open position and a storage position: when the key 1 is inserted into the key slot 201 and rotated to the open position, it can trigger the electrical switch of the automatic walking device; when the key 1 is inserted into the key slot 201 and rotated to the storage position, the automatic walking device is turned off; and, the direction in which the key 1 is rotated to the open position is opposite to the direction in which it is rotated to the storage position to prevent the key from being rotated in the opposite direction by accident.

[0052] Among them, when the key 1 is inserted into the key slot 201 and rotated along the key slot direction to the storage position, the electrical switch of the automatic walking device is out of the trigger state, and the key itself cannot be directly pulled out due to the restriction of the key slot structure, which can prevent the key from falling and being lost.

[0053] like Figure 2 and 3 As shown, the key 1 comprises a rocker 101 and a knob 102. The rocker 101 is positioned at the bottom of the knob and can be inserted into the keyhole 2. A key 103 is positioned on the side of the rocker 101. The key protrudes from the rocker 101 and is located between the knob 102 and the pressing portion 108. A key slot 201 corresponding in size to the key is provided in the keyhole 2. The key 103 can be inserted into and moved within the key slot 201. The key slot 201 includes a plug-in guide groove 2011 at its top entrance. The plug-in guide groove 2011 is positioned between the open position and the storage position. The key 103 can be switched between the storage position and the open position by rotating in opposite directions within the key slot 201. The key 1 can remain in either the storage position or the open position and cannot be directly removed along the direction of the plug-in guide groove 2011.

[0054] The bottom of the mounting base 4 may further be provided with an elastic body, which abuts between the bottom end of the rocker 101 and the bottom inner wall of the mounting base 4. When the key 1 is inserted into the mounting base 4, it is ejected by the elastic body without external pressure. In this embodiment, the elastic body 3 can be specifically implemented by a spring that can be compressed along the insertion guide groove 2011, which has the potential energy to push the rocker 101 toward the top of the mounting base.

[0055] A positioning structure may also be provided between the top of the mounting seat 4 and the key 1 , and the positioning structure is used to position the key 1 when it is rotated to a desired position. Figure 2 and 3 One positioning method is shown in FIG. A limiting mounting surface is provided between the top of the rocker 101 of the knob 102 and the knob 102, and a positioning protrusion 6 is provided on the bottom side of the limiting mounting surface. Correspondingly, two positioning holes 5 may be provided on the periphery of the keyhole 2. When the knob 102 is rotated to a certain position, the positioning protrusion 6 engages with the positioning holes 5, thereby positioning the key 1. To identify the different states of the key, the two positioning holes 5 may be provided corresponding to the key's open position (i.e., the ON position in the figure) and storage position (i.e., the STORAGE position in the figure). As the key 103 moves along the open state guide groove 2014 or the state guide groove 2012, the bottom side of the limiting mounting surface abuts the top of the mounting seat 4. When the key 103 reaches the open position and / or storage position, the positioning protrusion 6 enters the positioning hole 5, prompting the operator that the key has been rotated to the corresponding position and does not need to be rotated further.

[0056] In practice, the electrical switch 7 can be of various types, including push-type, contact-type, rocker-type, and so on. In this embodiment, the electrical switch 7 is a push-type electrical switch 7 disposed on the inner wall of the bottom of the mounting base. The electrical switch 7 is activated or deactivated by a pressing portion 108 disposed at the bottom end of the rocker 101.

[0057] Specifically, a relief portion 104 may be provided on one side of the bottom end of the rocker 101, and the relief portion 104 and the pressing portion 108 are respectively provided on both sides of the bottom end of the rocker 101. The relief portion 104 may be specifically provided as a notch located at the bottom end of the rocker 101, and the distance between the bottom end face of the relief portion and the knob 102 is smaller than the distance between the bottom end face of the pressing portion 108 and the knob 102. When the end of the rocker 101 is inserted into the keyhole 2 and is in the STORAGE position, the electrical switch 7 is in the area of ​​the relief portion 104 and is not touched, and the automatic walking device is in the off state; when the rocker 101 is in the ON position, the electrical switch 7 is touched and pressed down by the pressing portion 108, and the automatic walking device is in the on state. The specific shape and setting range of the relief portion 104 can be adjusted according to actual conditions.

[0058] In a more specific implementation, the pressing portion 108 may be further provided with a contact portion 105, which protrudes from the side of the pressing portion and is located at a radial position corresponding to the electrical switch. The bottom surface of the contact portion 105 is a transition surface 106 provided with an inclined angle. During the process of the rocker 101 rotating toward the open position, the key 103 moves toward the open position along the key slot, and the transition surface 106 first contacts the electrical switch 7. The electrical switch 7 is pressed by the transition surface 106 into the space between the bottom end surface of the pressing portion 108 and the bottom inner wall of the mounting seat 4 to reduce the impact on the pressing switch and make it easier to press the pressing switch. The electrical switch gradually enters the space between the bottom cross-section of the pressing portion 108 and the bottom inner wall of the mounting seat 4 from the transition surface 106 and is triggered by the key.

[0059] A limiting portion 107 may be further provided at the middle portion of the bottom end of the rocker 101 to limit the abutting position of the elastic body 3 .

[0060] The key slot 201 of the power switch of the present invention can be implemented in two specific ways, and the main difference lies in the different forms of the key slot 201.

[0061] like Figure 4 The figure shows an expanded view of the key slot 201 in the first embodiment. In this embodiment, the depth of the open position from the key hole 2 is equal to the depth of the storage position from the key hole 2. After the key 1 is pushed into the key hole, the ON position and the SOTRAGE position are set on the same cross section inside the mounting base, at the two ends of the state guide groove 2012. Figure 9 The figure shows an expanded view of the keyway 201 in a second implementation. In this implementation, the depth of the open position from the keyhole 2 is greater than the depth of the stored position. When the key 1 is inserted into the keyhole, it first reaches the stored position guide groove 2013 at a first depth. After rotating within the stored position guide groove 2013 to the SOTRAGE position, the key must be pushed in again and rotated to reach the ON position at a second depth. In this implementation, the ON and SOTRAGE positions are located on different cross-sections of the keyhole 2.

[0062] In order to clearly show the structure of the keyway 201 and the contact between the end of the rocker 101 and the keyhole 2, the mounting base 4 is partially cut away.

[0063] In the first implementation, the key slot 201 includes a plug-in guide slot 2011 and a state guide slot 2012. The plug-in guide slot 2011 is arranged in a direction parallel to the axis of the mounting seat 4, and the state guide slot 2012 is arranged perpendicular to the plug-in guide slot 2011. The middle of the state guide slot 2012 is connected to the bottom end of the plug-in guide slot 2011. The open position is located at one end of the state guide slot 2012, and the storage position is located at the other end of the state guide slot 2012.

[0064] In this way, if Figure 5 As shown, the rocker 101 is inserted into the key hole 2, and the key 103 moves along the track defined by the insertion guide groove 2011. Figure 6 As shown, after the push rocker 101 is pushed down to the limit position, the rocker 101 can be swung at the depth position so that the key 103 on the rocker 101 rotates to both sides along the state guide groove 2012 to reach the ON position or the STORAGE position. Figure 7 The figure shows a schematic diagram of the rocker 101 when it is swung to the STORAGE position. At this time, the electrical switch 7 is not pressed by the pressing portion 108 at the bottom of the rocker 101 and is in the closed state. At the same time, the key 1 is fixed in the keyhole 2. Figure 8 The figure is a schematic diagram when the rocker 101 is swung to the ON position. At this time, the electrical switch 7 is pressed and is in the power-on state, and the key 1 is fixed in the keyhole 2.

[0065] In the second implementation, the key slot 201 includes a plug-in guide slot 2011, a storage state guide slot 2013, a connection guide slot 2015 and an open state guide slot 2014: the plug-in guide slot 2011 is arranged in a direction parallel to the axis of the mounting seat 4; the storage state guide slot 2013 is arranged perpendicular to the plug-in guide slot 2011, and the first end of the storage state guide slot 2013 is connected to the bottom end of the plug-in guide slot 2011, and the storage position is located at the second end of the storage state guide slot 2013; the open state guide slot 2014 is arranged in a direction parallel to the axis of the mounting seat 4; the storage state guide slot 2013 is arranged perpendicular to the plug-in guide slot 2011, and the first end of the storage state guide slot 2013 is connected to the bottom end of the plug-in guide slot 2011, and the storage position is located at the second end of the storage state guide slot 2013; 014 is set to be perpendicular to the plug-in guide groove 2011, the open position is located at the first end of the open state guide groove 2014, and the depth of the open state guide groove 2014 from the keyhole is greater than the depth of the open state guide groove 2014 from the keyhole; the connecting guide groove 2015 is set to be parallel to the plug-in guide groove 2011, and the top end of the connecting guide groove 2015 is connected to the second end of the storage state guide groove 2013, and the bottom end of the connecting guide groove 2015 is connected to the second end of the open state guide groove 2014.

[0066] In this way, if Figure 10As shown, the rocker 101 is inserted into the keyhole 2, and the key 103 first moves along the trajectory defined by the insertion guide groove 2011. After pushing the rocker 101 until the insertion guide groove 2011 is at the limit position of the first depth, the rocker 101 can be swung to rotate along the storage state guide groove 2013 to reach the STORAGE position. Figure 11 The figure shows the rocker 101 when it is swung to the STORAGE position. At this time, the electrical switch 7 is not pressed and is in the OFF state. At the same time, the key 103 of the key 1 is embedded in the positioning groove 202 set at one end of the storage state guide groove 2013 under the action of the elastic body 3, so that the key is fixed in the keyhole 2 and positioned. Figure 12 As shown, continue to push the key 1 until the connecting guide groove 2015 connected to the storage state guide groove 2013 in the vertical direction is at the limit position of the second depth, and then rotate the rocker 101 in the opposite direction to make it rotate along the opening state guide groove 2014 to the ON position. Figure 13 The figure is a schematic diagram when the rocker 101 is swung to the ON position. At this time, the electrical switch 7 is pressed and is in the power-on state, and the key 1 is fixed in the keyhole 2.

[0067] The positioning groove can be specifically arranged in the open position and / or the storage position of the storage state guide groove 2013 and / or the state guide groove 2012. The positioning groove 202 has a recessed portion toward the top of the mounting seat, which can accommodate and fix the key 103 that is upwardly spring-loaded and abutted by the spring, thereby fixing the key and preventing it from sliding out of the corresponding position.

[0068] In both implementations, as the key 103 is inserted into the open-state guide slot 2014 or the state guide slot 2012 and moves along the open-state guide slot 2014 or the state guide slot 2012, the pressing portion 108 synchronously rotates within the mounting seat 4, pressing or releasing the electrical switch 7. Therefore, in both implementations, the angular range of the avoidance portion 104 can be adjusted so that the switch is pressed and energized only when the key 1 is turned to the ON position.

[0069] This embodiment only shows one form of the electrical switch 7. In actual use, the electrical switch 7 may be of other forms, and the structure in which the power on and off process can be completed by touching or toggling the rocker 101, etc.

[0070] In this embodiment, only two positioning structures are shown. In actual use, the key 1 can be positioned in the STORAGE position and the ON position by other positioning structures. In the OFF position, the key can be inserted and removed through the vertical insertion guide groove 2011.

[0071] Thus, the present invention reverses the on and stored positions of the switch through the keyway, making it possible to clearly define the rotational direction of each position when the switch is in use, thereby avoiding the problem of blurring the boundaries between the different positions due to the same rotational direction of the on and stored positions. The present invention can improve the safety of power switch operation.

[0072] The above is merely an embodiment of the present invention, and its description is relatively specific and detailed, but it should not be understood as limiting the scope of the present invention. It should be pointed out that those skilled in the art can make a number of modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
