[0046] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Examples of these preferred embodiments are illustrated in the accompanying drawings, and the embodiments of the present invention shown in the accompanying drawings and described according to the accompanying drawings are merely exemplary, and the present invention is not limited to these embodiments.

[0047] See also Figure 1 to Figure 3 As shown, a locking assembly 100 provided by the present invention is used to lock and connect the first assembly in the housing 10. Furthermore, the locking assembly 100 is arranged in a one-to-one correspondence with the first assembly, including a locking unit 20 and a release unit 30.

[0048] The housing 10 includes a plurality of side walls 11, which enclose a receiving cavity 12 for receiving the first component. The locking unit 20 and the release unit 30 are respectively arranged on the housing 10 and / or the first component to lock and connect the first component in the housing 10.

[0049] In the present application, the locking unit 20 includes a locking rail 21 and a locking member 22 corresponding to the locking rail 21; in a preferred embodiment of the present application, the locking rail 21 is arranged on the outer shell of the first component and is located on both sides of the outer shell of the first component in the width direction.

[0050] Furthermore, a plug-in guide rail 13 corresponding to the locking guide rail 21 is provided in the receiving cavity 12 of the shell 10. When the first component is inserted into the receiving cavity 12, the locking guide rail 21 cooperates with the plug-in guide rail 13 to ensure that the first component accurately enters the receiving cavity 12, thereby preventing deformation / damage of the first component / shell 10 caused by position deviation when the first component is docked with the receiving cavity 12, thereby ensuring the safety of the locking component 100 and the first component.

[0051] See also Figure 4 Combined with Figure 1 to Figure 3 As shown, the locking member 22 has a limit block 23 and a connecting shaft 24 for connecting the limit block 23 and the release unit 30; wherein, the limit block 22 is used to lock the first component in the receiving cavity 12, and in the present application, the locking guide rail 21 has a limit groove 25 arranged corresponding to the limit block 23; in this arrangement, when the first component is locked in the receiving cavity 12, the limit block 23 is clamped in the limit groove 25 to further limit the clamping position of the first component and the shell 10.

[0052] In a preferred embodiment of the present application, the limit block 23 has a connecting portion 231 for connecting the connecting shaft 24, a fixing portion 232 for connecting the release unit, and a limit portion 233 for limiting the first component, wherein the limit portion 233 is formed by an inward depression on the side of the limit block 23 away from the connecting portion 231, so that the limit block 23 in this embodiment is roughly arranged in a "T" shape.

[0053] In the present application, the limit blocks 23 are arranged in pairs, and the two limit blocks 23 are connected into a whole through a rotating shaft 24 and are located on both sides of the width direction of the shell 10. Furthermore, the locking member 22 also includes an elastic element 26, and the elastic element 26 is located between the limit block 23 and the shell 10. It is defined that when the limit block 23 is engaged with the limit groove 25 to lock the first component, the limit block 23 is in a protruding position; when the limit block 23 is separated from the limit groove 25 to release the first component, the limit block 23 is in a retracted position, and the elastic element 26 can drive the limit block 23 to switch between the protruding position and the retracted position.

[0054] In the present application, a fixing column 27 for fixing the elastic element 26 is also provided on the fixing portion 232 of the limit block 23, and a limiting structure 14 corresponding to the fixing column 27 is provided on the shell 10. Such a setting can effectively prevent the elastic element 26 from detaching from between the limit block 23 and the shell 10; preferably, the limiting structure 14 is a limiting groove arranged in a groove shape.

[0055] The shell 10 is also provided with a limiting protrusion 15 for blocking and limiting the limiting block 23. In the present embodiment, the limiting protrusion 15 is located on one side of the radial direction of the connecting shaft 24, and the limiting protrusion 15 is located on the side where the fixing portion 232 and the fixing column 27 are arranged opposite to each other. Such an arrangement can provide a reverse force acting on the limiting portion 233 to lock the first component in the receiving cavity 12.

[0056] Furthermore, when the limit block 23 is clamped in the limit groove 25 and is in a protruding position, the end of the limit portion 233 is abutted against the groove wall of the limit groove 25 to further prevent the limit block 23 from escaping from the limit groove 25; and when the limit block 23 is partially escaping from the limit groove 25 and is in a retracted position, the limit portion 233 is accommodated in the groove body.

[0057] The release unit 30 is used to release the first component so that it can be easily and quickly detached from the receiving cavity 12. In the present application, the release unit 30 has a connecting member 31, an unlocking button 32 rotatably connected to the connecting member 31, and a connecting rod 33 for connecting the locking member 22.

[0058] See also Figure 5 Combined with Figure 1 to Figure 3 As shown, the connecting member 31 is used to position the unlocking button 32 so that the unlocking button 32 can drive the locking member 22 connected thereto to rotate and switch the connection state between the first component and the shell 10; in a preferred embodiment of the present application, the connecting member 31 includes a pressure plate 311 detachably connected to the shell 10 and a pivot shaft 312 fixed on the pressure plate 311 for connecting the unlocking button 32; further, the unlocking button 32 is rotatably mounted on the inner side of the pressure plate 311 through the pivot shaft 312 so that the unlocking button 32 is accommodated in the accommodating cavity 12.

[0059] In this embodiment, the pivot axis 312 is arranged at a position approximately in the middle of the unlocking button 32, and the unlocking button 32 has a pressing end 321 and a connecting end 322 which are respectively arranged on both sides of the axial direction of the pivot axis 312, wherein the pressing end 321 passes through the pressure plate 311 and partially protrudes out of the accommodating cavity 12; the connecting end 322 is accommodated in the accommodating cavity 12, and the end of the connecting end 322 has a card slot 323 for clamping the connecting rod 33.

[0060] One end of the connecting rod 33 is rotatably connected to the connecting end 322 via a slot 323; the other end is connected to the limit block 23 via a connecting hole (unnumbered) provided on the fixed end 232. With such a configuration, the limit block 23 can be controlled by pressing the unlocking button 32, thereby effectively improving the convenience of the power system 100 when releasing the first component.

[0061] Preferably, a connecting rod limiting rib 16 for limiting the transmission position of the connecting rod 33 is also provided on the shell 10, and the connecting rod limiting rib 16 is formed by folding the side wall 11 of the shell 10 toward the inside of the accommodating cavity 12 to prevent the connecting rod 33 from being detached from the connecting hole on the fixed end 232 of the limiting block, causing abnormal use of the release unit 30.

[0062] Specifically, the locking assembly 100 of the present application is configured with a connecting rod / coupling shaft structure so that each component is configured with a hinged four-bar mechanism. In a preferred embodiment of the present application, the two limit blocks 23 are rotatably mounted on the mounting shell 52 on both sides of the shell 32 through the connecting shaft 24, so that the connecting shaft 24 can drive the limit blocks to rotate synchronously on the mounting shell 52; at the same time, the limit block 23 is formed by a limit portion 233 formed by a recess, so that the extended end of the limit portion 233 abuts against the groove wall of the limit groove 25 of the first component, and the side wall surface of the limit portion 233 can abut against the protrusion 15 on the shell 10, so that while limiting the rotation of the limit block 23, the protrusion 15 applies a reverse force to the limit block 23 to lock the first component in the accommodating cavity 12.

[0063] When the unlocking button is pressed, the connecting rod 33 is pulled, and the connecting rod 33 simultaneously pulls the limit block and the connecting shaft 24 to rotate synchronously in the mounting shell hole, and the limit portion 233 retracts into the mounting shell 52, and the first component is ejected under the action of the elastic release structure.

[0064] It should be noted that in the drawings of the specification of the present application, the first component is only shown as an energy device / battery pack for illustrative purposes. In other embodiments of the present application, the first component may also be a component with other functions / structures, that is, the specific structure and function of the first component may be selected according to actual needs and is not limited here.

[0065] See also Figure 6 to Figure 8 As shown, an energy supply system 200 provided by the present application is provided. The energy supply system 200 locks and connects the energy device 4 in the housing 10 through the locking assembly 100 of the present application, and finally realizes the transmission and supply of energy.

[0066] Specifically, the energy supply system 200 of the present application has a shell 10, an energy device 4 and a control device 5 accommodated in the shell 10, and a locking assembly 100 for locking the energy device 4 in the shell 10, and in the present application, the shell 10 and the locking assembly 100 have substantially the same structure as the aforementioned shell 10 and the locking assembly 100. The following specification section will describe in detail the differences between the energy supply system 200 and the shell 10 and the locking assembly 100, and the same parts will not be repeated here.

[0067] See also Figure 6 to Figure 8 Combined with Figure 1 to Figure 3 As shown, the energy device 4 and the control device 5 are arranged one-to-one with the locking assembly 100, and have a shell (not numbered) for accommodating the energy unit (or battery cell) and a plug-in 41 that penetrates the shell. Furthermore, the shell 10 is provided with a plug-in seat 17 that is arranged corresponding to the plug-in 41. In this embodiment, the locking guide rail 21 is arranged on the shell of the energy device 4. In this way, when the energy device 4 is inserted into the receiving cavity 12, the locking guide rail 21 cooperates with the plug-in guide rail 13 to ensure that the energy device 4 accurately enters the receiving cavity 12, so that the plug-in seat 17 and the plug-in 41 are accurately docked, and deformation / damage of the plug-in seat 17 and the plug-in 41 caused by position deviation when the energy device 4 is docked with the receiving cavity 12 is prevented, thereby ensuring the service life and safety of the energy supply system 200.

[0068] Furthermore, the release unit 30 in this embodiment also has an elastic release structure 34 arranged between the energy device 4 and the shell 10. The elastic release structure 34 is extended along the plug-in direction of the energy device 4 to elastically support the elastic release structure 34. In this way, when the energy device 4 is in a released state, the elastic release structure 34 can push the energy device 4 out of the accommodating cavity 12 to facilitate the removal of the energy device 4.

[0069] Preferably, the energy device 4 is plugged in in the up-and-down direction, the elastic release structure 34 is located at the bottom of the accommodating cavity 12 , and two elastic release structures 34 are provided, and the two elastic release structures 34 are symmetrically arranged on both sides of the midline of the energy device 4 in the length direction.

[0070] In a preferred embodiment of the present application, the energy device 4 is a battery pack, which is accommodated in the accommodating cavity 12, and the plug 41 of the battery pack is electrically connected to the plug seat 17 to achieve the output of electrical energy; of course, the energy device 4 can also be other energy structures for providing energy, which is not limited here.

[0071] In this embodiment, one or more energy devices 4 may be provided, and when multiple energy devices 4 (at least 2) are provided, the energy devices 4 are connected in parallel to avoid abnormal use of a single energy device 4 affecting the normal operation of the energy supply system 200, thereby ensuring the normal use of the energy supply system 200; of course, in other embodiments of the present application, multiple energy devices 4 may also be connected in series, and at this time the energy supply system 200 can achieve high voltage output.

[0072] See also Fig. 9 , Fig.10 As shown, the control device 5 has a PCB board 51 and a mounting shell 52 for accommodating the PCB board 51. In the present application, the control device 5 is accommodated in the accommodating cavity 12 of the housing 10. Preferably, the plug seat 17 is integrated on the PCB board 51. Such a configuration can facilitate the control device 5 to complete the control of the energy device 4 through the cooperation of the plug seat 17 and the plug 41, so as to reduce the volume of the energy supply system 200 while ensuring the normal transmission of energy by the energy device 4.

[0073] When using the energy supply system 200 of the present application, the locking guide rail 21 on the outer shell of the energy device 4 cooperates with the plug-in guide rail 13 in the shell 10, so that the energy device 4 is plugged into the accommodating cavity 12 along the plug-in direction; further, when the energy device 4 slides along the plug-in guide rail 13, the locking guide rail 21 presses on the surface of the limit block 23, so that the elastic element 26 is compressed and the limit block 23 is in a retracted position; when the energy device 4 slides to the bottom of the accommodating cavity 12, the elastic release structure 34 at the bottom of the accommodating cavity 12 is compressed, and the limit block 23 pops up under the action of the elastic element 26 to be in a protruding position, and is clamped in the limit groove 25 of the locking guide rail 21, so that the plug 41 is plugged into the plug seat 17, thereby realizing the electrical connection between the energy device 4 and the PCB board 51, and realizing the transmission of electrical energy.

[0074] Furthermore, when the energy of the energy device 4 is exhausted / an abnormality occurs and the energy device 4 needs to be removed, pressing the pressing end 321 causes the unlocking button 32 to rotate about the pivot shaft 312, and further drives the connecting end 322 to rotate, so as to drive the limit block 23 to compress the elastic element 26 through the connecting rod 33, so that the limit block 22 rotates from the protruding position to the retracted position. At this time, the elastic release structure 34 recovers from the compressed state to the elastic telescopic state, the plug seat 17 is separated from the plug 41 of the energy device 4, and the energy device 4 is in the released state and protrudes outward from the accommodating cavity 12 to facilitate the removal of the energy device 4 and replacement / charging.

[0075] It should be noted that in the present application, only an example is taken in which the energy supply system 200 has two energy devices 4 and two locking assemblies 100 corresponding to the energy devices 4. Furthermore, in other embodiments of the present application, the locking unit 20 can also be arranged on the inner side of the side wall 11, and at this time the release unit 30 is arranged on the energy device 4, that is, in the present application, the specific setting positions of the locking unit 20 and the release unit 30 can be selected according to actual conditions. The embodiments of the present application are merely exemplary and should not be limited to this.

[0076] See also Fig.11 , Fig.12 Combined with Figure 6 to Figure 8 As shown, the present invention further discloses a gardening tool 300, including a protective cover 301, a motor (not shown), a working unit 302 drivingly connected to the motor, and an energy supply system 200 for providing energy to the motor.

[0077] In this embodiment, the motor and the working unit 302 are arranged on both sides of the protective cover 310. Furthermore, the shell 10 has a first receiving cavity (unnumbered) for receiving the energy device 4 and a second receiving cavity (unnumbered) for receiving the motor, and the driving shaft of the motor passes through the protective cover 310 to be driven and connected to the working unit 302 located on the other side of the protective cover 310.

[0078] In a preferred embodiment of the present application, the shell 10 and the protective cover 301 are integrally formed, and the protective cover 230 is also provided with a cover plate 303 for covering the energy supply system 200. Such a configuration can effectively prevent foreign objects from entering the energy supply system 200 during the use of the garden tool 300, causing abnormal use of the energy supply system 200; preferably, at least two energy devices 4 are provided in this embodiment, and the locking unit 20 and the release unit 30 are respectively provided corresponding to the energy devices 4, and the energy devices 4 are connected in parallel; such a configuration, the PCB board 51 can control the two energy devices 4 to work simultaneously / separately. Specifically, the two energy devices 4 usually work simultaneously, but when the energy of one energy device 4 is too low / abnormal, the energy device 4 can be released separately by pressing the locking device 30, and then the other energy device 4 enters the use state under the control of the PCB board 51 to ensure the endurance of the garden tool 300.

[0079] In a preferred embodiment of the present application, the garden tool 300 is a lawn mower, and the working unit 302 is a mowing unit. Of course, in other embodiments of the present application, the garden tool 300 can also be other tools used for gardening work; that is, the embodiments shown in the specification and drawings of this application are merely exemplary and should not be limited thereto.

[0080] In summary, the locking assembly 100 of the present invention realizes the rapid installation and disassembly between the first assembly / energy device 4 and the housing 10 by setting the locking unit 20 and the release unit 30, facilitates the use of the locking assembly 100, and has the advantages of reliable structure and convenient operation. At the same time, the energy supply system 200 and the garden tool 300 using the locking assembly 100 of the present invention can facilitate the replacement and charging of the energy device 4, effectively ensure the power supply capacity of the energy supply system 200 and the endurance of the garden tool 300, and improve the practicality of the energy supply system 200 and the garden tool 300 of the present application.
