Abstract
Description
Technical Field
[0001] This utility model belongs to the field of garden machinery technology and relates to a locking structure for a lawnmower cabin cover. Background Technology
[0002] Existing lawnmower products generally adopt a top-embedded control panel design, which uses an openable and closable cover to physically protect the human-machine interface. However, the existing covers are usually opened and closed separately by buckles or hinges, and users need to operate them manually to access the control interface. Although this can effectively block environmental pollutants such as rainwater and dust, in emergency situations such as mechanical malfunctions or obstacles, users need to open the cover first to trigger the built-in emergency stop button. The disruption of the operating chain causes a response delay and poses a safety hazard. Especially in scenarios such as working on slopes or slippery weather, the coordinated action of opening the cover and stopping the emergency stop with both hands significantly increases the operational risk. Utility Model Content
[0003] This utility model aims to improve the user's operating experience and response efficiency when controlling a lawnmower. It provides a lawnmower hatch cover locking structure, which links the hatch cover of the control panel compartment with the emergency stop button. This allows the hatch cover to be unlocked and opened when the emergency stop button is pressed, and the emergency stop button to be reset when the hatch cover is closed. Users only need to operate the emergency stop button or the hatch cover, which greatly reduces the complexity of operation and improves the response efficiency and safety of operation while ensuring the reliability of protection.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A lawnmower hatch locking structure includes a rotatable rocker arm, an emergency stop button, and a locking spring. The rocker arm has a latch and a lever at each end, with the lever abutting against the emergency stop button. One end of the hatch has a locking end for abutting against the latch and activating it. The locking end has a locking hole for receiving and engaging the latch. The locking spring has two ends connected to the latch and the lawnmower, respectively, and provides a spring force to the latch towards the locking end.
[0006] Furthermore, the lawnmower is provided with recesses at the top and bottom for accommodating the emergency stop button, and the interior of the recesses is provided with contacts for triggering the emergency stop button by contacting its bottom.
[0007] Furthermore, the lever extends into the groove and abuts against the bottom of the emergency stop button.
[0008] Furthermore, the locking end is provided with a first rounded corner, and the buckle is provided with a second rounded corner for contacting and sliding relative to the first rounded corner.
[0009] Furthermore, the other end of the hatch is provided with a hinged end for rotatably connecting with the lawnmower, and a torsion spring is provided on the hinged end.
[0010] Furthermore, the lawnmower includes a main body and a housing disposed on the main body. The main body is provided with an operation panel compartment, and the housing has an opening communicating with the operation panel compartment. The hinged end of the cover is hinged to the housing to open and close the operation panel compartment.
[0011] Furthermore, the hatch has a fully open angle of 90° relative to the housing.
[0012] Furthermore, it also includes a buffer spring, one end of which is connected to the housing and the other end faces the hinge end. When the hatch is rotated to a set angle, the other end of the buffer spring abuts against the hinge end.
[0013] Furthermore, the set angle is 60°.
[0014] Furthermore, a drive wheel is provided at the front end of the main body along its direction of travel.
[0015] In summary, the advantages of this utility model are as follows:
[0016] This utility model uses a locking structure to link the hatch cover of the control panel compartment with the emergency stop button, so that pressing the emergency stop button unlocks the hatch cover to open it, and closing the hatch cover resets the emergency stop button. Users only need to operate the emergency stop button or the hatch cover during operation, which greatly reduces the complexity of operation, and improves the efficiency of operation response and the safety of operation while ensuring the reliability of protection.

[0022] 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. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.
[0023] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. 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.
[0024] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.
[0025] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.
[0026] This utility model embodiment provides a locking structure for a lawnmower hatch 1, wherein the lawnmower includes a main body and a shell disposed outside the main body, and a mowing disc is provided at the bottom of the main body. The lawnmower performs mowing operations through the mowing disc during self-driving.
[0027] The main body of the lawnmower is divided into a front end and a rear end along the direction of travel. The front end of the main body is equipped with a drive wheel, and the rear end is equipped with a rear wheel. The rear wheel is preferably a driven swivel wheel. The drive wheel provides driving drive for the entire lawnmower. Therefore, the lawnmower in this embodiment is a front-wheel drive type, driven by the front wheel.
[0028] The main body houses the battery pack, control unit, drive unit, equipment mounting bracket, camera module, and other components located inside the casing.
[0029] The battery pack and mowing disc are located in the middle of the main body in the front-to-back direction, between the drive wheel and the caster wheel, so that the overall center of gravity of the lawnmower is centered or forward. The lateral width of the front end of the housing is greater than that of the rear end, and the width of the housing gradually decreases from the front end to the rear end of the main body. This can reduce lateral deviation during driving and improve the overall stability during driving and mowing.
[0030] Reference Figure 1 The main body also features an operation panel compartment 4, which allows users to control the lawnmower's various settings. The casing has an opening connecting to the inner compartment and a hinged cover 1 at the opening for opening and closing the operation panel compartment 4. One end of the cover 1 is a hinged end 11. (Refer to...) Figure 2 The hinge end 11 is hinged to the shell to realize the flipping opening and closing action of the hatch 1. The other end of the hatch 1 is the locking end 12. The latch structure is set on the shell near the locking end 12. The connection state switching between the latch structure and the locking end 12 forms a locking / unlocking effect on the hatch 1.
[0031] Reference Figure 3 and Figure 4 The locking structure includes a rocker arm and a locking spring 24. The middle part of the rocker arm is rotatably connected to the housing via a pivot 23. One end of the rocker arm is provided with a latch 21. The rotation of the rocker arm around the pivot 23 causes the latch 21 to swing toward / away from the locking end 12. The locking spring 24 is provided on the latch 21 on the side opposite to the locking end 12. The two ends of the locking spring 24 are connected to the latch 21 and the housing respectively. The locking spring 24 provides a spring force to the latch 21 toward the locking end 12.
[0032] The locking end 12 has a locking hole 121 in the middle for inserting the buckle 21 to form a snap-fit. When the buckle 21 is in the locking hole 121, the bottom of the buckle 21 abuts against the bottom wall of the locking hole 121. Under the elastic force of the locking spring 24 on the buckle 21, the buckle 21 is maintained in the state of being inserted into the locking hole 121, thereby locking the buckle 21 and the locking end 12, and locking the hatch 1 in the closed state.
[0033] When the hatch 1 is locked and needs to be unlocked, the latch 21 is disengaged from the lock hole 121 by actively rotating the rocker arm, thereby releasing the lock on the locking end 12 and allowing the hatch 1 to be opened.
[0034] When the hatch 1 is in the unlocked open state and needs to be locked and closed, the closing action of the hatch 1 causes the locking end 12 to approach and contact the latch 21. The locking end 12 pushes the latch 21 to rotate and compress the spring. During the further closing action of the hatch 1, the latch 21 abuts against the locking end 12 and slides relative to the surface of the locking end 12 until the latch 21 slides to the position directly opposite the lock hole 121. At this time, the latch 21 enters the lock hole 121 under the push of the spring's return, thereby achieving the locking of the hatch 1 when it is closed. (Refer to...) Figure 3 .
[0035] The bottom of the locking end 12 of the preferred hatch 1 is provided with a first rounded corner, and the buckle 21 is provided with a second rounded corner. When the locking end 12 contacts the buckle 21, the buckle 21 is pushed to rotate more stably through the contact between the first rounded corner and the second rounded corner, and the buckle 21 can slide more smoothly relative to the surface of the locking end 12.
[0036] To enable the lawnmower's emergency stop function, an emergency stop button 3 is also provided on the housing. The housing has recesses at the top and bottom for accommodating the emergency stop button 3. The emergency stop button 3 is located in the recess and forms a gap fit with the inner wall of the recess, allowing the emergency stop button 3 to move within the recess. A contact point 31 is provided at the bottom of the recess. When the emergency stop button 3 is pressed deep into the recess, the contact point 31 can be triggered, thereby generating a signal for the lawnmower to stop urgently.
[0037] The other end of the rocker arm, symmetrical about the pivot 23 and away from the latch 21, is set as a lever 22. The lever 22 extends into the groove and contacts the bottom of the emergency stop button 3. When the cover 1 is closed and locked, the lever 22 abuts against the emergency stop button 3, keeping the emergency stop button 3 in the raised, untriggered position. When the emergency stop button 3 is pressed to stop the lawnmower in an emergency, the pressing action of the emergency stop button 3 simultaneously presses the lever 22, causing the rocker arm to rotate the latch 21 and disengage from the lock hole 121. This allows the cover 1 to open simultaneously when the emergency stop button 3 is pressed to stop the lawnmower, making it convenient for the user to operate directly from the control panel 4.
[0038] When the hatch 1 is closed, the rocker arm resets simultaneously, causing the lever 22 to reset the emergency stop button 3 to the untriggered position.
[0039] To ensure that the hatch 1 can open automatically after being unlocked, a torsion spring is provided on the hinge end 11 of the hatch 1. When the hatch 1 is closed, the torsion spring has elastic potential energy due to torsion. Thus, when the hatch 1 is unlocked, the torsion spring is released to realize the automatic opening of the hatch 1.
[0040] Preferably, the hatch 1 is fully opened at an angle of 90° relative to the shell.
[0041] Furthermore, a buffer spring 111 is also provided on the housing. The buffer spring 111 is located near the hinge end 11 of the hatch 1. One end of the buffer spring 111 is connected to the housing, and the other end faces the hinge end 11. When the hatch 1 is opened to a set angle less than the fully open angle, the other end of the buffer spring 111 will contact the hinge end 11, forming a reaction force in the opposite direction of the opening direction of the hatch 1. This dampens the opening action of the hatch 1, reduces the opening speed and inertia of the hatch 1, and makes the hatch 1 open from fast to slow, with a gentler action and less inertial vibration, effectively improving the user experience.
[0042] Preferably, the set angle at which the hatch 1 opens to contact the buffer spring 111 is 60°.
[0043] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort should fall within the protection scope of this utility model.
