DETAILED DESCRIPTION
[0117] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0118] In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "axial," "radial," "circumferential," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.
[0119] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Thus, features defined as "first" or "second" may explicitly or implicitly include at least one of these features.
[0120] In order to facilitate use, electric equipment usually uses a battery pack to power the electric equipment. In order to facilitate the installation of the battery pack, a battery pack installation structure is provided on the electric equipment. The battery pack installation structure includes a mounting body, a hatch and a locking mechanism. The mounting body is used to carry the battery pack. The hatch can be movably installed on the mounting body and is used to cooperate with the mounting body to form a cavity for accommodating the battery pack. The hatch is provided with a first position that cooperates with the mounting body to close the cavity to prevent grass clippings from entering the cavity. The user unlocks the battery pack in the cavity by activating an unlock button in the locking mechanism.
[0121] Due to the heavy weight of the battery pack in the electric device, the battery pack ejection mechanism located in the cavity cannot eject the battery pack. In some embodiments, on the one hand, the user needs to use one hand to continuously activate the unlock button while the other hand needs to support the hatch. However, since the user cannot reach the battery pack in the cavity, one hand must be freed to take the battery pack in the cavity, which is extremely inconvenient. On the other hand, the operator needs to perform an additional unlocking action to remove the battery pack from the cavity.
[0122] To address the aforementioned issues, the present application provides a battery pack mounting structure comprising a mounting body, a hatch, and a locking mechanism. The mounting body is used to support the battery pack. The hatch is movably mounted to the mounting body and is used to cooperate with the mounting body to form a cavity for accommodating the battery pack. The hatch has a first position in which it cooperates with the mounting body to seal the cavity, and a second position in which it is opened to provide access to the battery pack. The locking mechanism is used to lock or unlock the battery pack. The hatch moves from the first position to the second position, triggering a change in the position of the locking mechanism to unlock the battery pack. Compared to the prior art method of first opening the hatch, then operating the unlock button to unlock the battery pack, and then removing the battery pack, the solution provided by the present application makes battery pack removal simple, convenient, and quick.
[0123] Specifically, in one embodiment, as shown in FIG. 1 to FIG. 15 , the battery pack mounting structure includes:
[0124] An installation body 1, which is used to carry a battery pack 9;
[0125] a hatch 2 movably mounted to the mounting body 1 and configured to cooperate with the mounting body 1 to form a cavity 14 for accommodating the battery pack 9, the hatch 2 having a first position in which it cooperates with the mounting body 1 to close the cavity 14, and a second position in which the cavity 14 is opened to provide access to the battery pack;
[0126] The locking mechanism 3 is used to lock or unlock the battery pack 9. The hatch 2 is linked to the locking mechanism 3. When the hatch 2 moves from the first position to the second position, the position of the linked locking mechanism 3 changes to unlock the battery pack 9.
[0127] The battery pack mounting structure also includes an opening 15 for opening the hatch 2 to provide access to the battery pack 9. The mounting body 1 is also equipped with a slide rail to guide the battery pack 9 into and lock it into the cavity. In the technical solution provided by this application, during the process of opening the hatch 2, the hatch 2 can drive the locking mechanism 3 to unlock the battery pack 9, eliminating the need for additional unlocking of the battery pack 9. In other words, after opening the hatch 2, the battery pack 9 is unlocked, and the battery pack can be removed from the cavity 14. This operation is simple, convenient, and quick, and there is no need for an additional unlocking member to drive the locking mechanism of the battery pack 9 to unlock the battery pack 9.
[0128] In one embodiment, as shown in FIG1-8 , when the hatch 2 is in the first position, the locking mechanism 3 locks the battery pack 9. The locking mechanism 3 is coupled to the hatch 2 by a mechanical connection, so that when the hatch 2 is opened, the hatch 2 can drive the locking mechanism 3 to unlock the battery pack 9. The locking mechanism 3 includes:
[0129] The main locking member 31 has a locking position for locking the battery pack 9 in the cavity 14 and an unlocking position for releasing the battery pack 9 in the cavity 14;
[0130] The linkage assembly is connected to the hatch cover 2 and can act on the main locking member 31. When the hatch cover 2 moves from the first position to the second position, the linkage assembly drives the main locking member 31 to move from the locked position to the unlocked position.
[0131] In one embodiment, the battery pack mounting structure further includes a reset assembly, which is configured to move the primary locking member 31 from the unlocked position to the locked position when the hatch 2 transitions from the second position to the first position. In other words, as the hatch 2 closes the opening of the cavity 14, the reset assembly automatically locks the battery pack 9 by driving the primary locking member 31. No additional locking action is required; simply closing the hatch 2 suffices.
[0132] Optionally, the reset component includes:
[0133] A base 33 is provided on the mounting body 1, and the primary locking member 31 is movably mounted in the base 33; and
[0134] The first elastic member 34 has one end that pushes against the base 33 and the other end that pushes against the main locking member 31. When the hatch 2 moves from the second position to the first position, the main locking member 31 moves from the unlocked position to the locked position under the action of the first elastic member 34.
[0135] Specifically, as shown in FIG8 , the base 33 may be provided with a slot, and the primary locking member 31 may be partially disposed within the slot, enabling it to move up and down along a direction defined by the slot (roughly perpendicular to the direction of movement of the movable member 32). The first elastic member 34 may be a coil spring, with spring seats disposed on the base 33 and the primary locking member 31, respectively. One end of the coil spring is mounted on the spring seat of the base 33, and the other end is mounted on the spring seat of the primary locking member 31.
[0136] The base 33 may be formed separately and then mounted on the mounting body 1 , or the base 33 may be directly formed on the mounting body 1 .
[0137] In one embodiment, the hatch cover 2 is hinged to the mounting body 1 and can rotate to a first position and a second position around the axis of the hinge shaft 4, respectively. The linkage assembly includes:
[0138] a toggle member 35 rotatably connected to the hatch cover 2 so as to rotate about the axis of the hinge shaft 4; and
[0139] The moving member 32 abuts against the toggle member 35 and can act on the main locking member 31. When the hatch 2 rotates from the first position to the second position, the toggle member 35 pushes against the moving member 32, and the moving member 32 drives the main locking member 31 to move from the locked position to the unlocked position.
[0140] Optionally, the hinge shaft 4 is connected to the hatch cover 2 around its axis so as to rotate synchronously, and the toggle member 35 is provided on the hinge shaft 4 .
[0141] Specifically, in the embodiment shown in Figure 6 , the hatch cover 2 includes a hatch cover body 21 and pivoting portions 22 on opposite sides of the hatch cover body 21. The hinge shaft 4 is synchronously rotatably connected to the pivoting portions 22, for example, via a spline connection. When the hatch cover 2 rotates from a first position to a second position relative to the mounting body 1, the hinge shaft 4 rotates the toggle member 35, thereby driving the movable member 32 to move. The movable member 32 then drives the primary locking member 31 from a locked position to an unlocked position.
[0142] In one embodiment, the linkage assembly is provided with a guide portion, and the main locking member 31 is connected to the moving member 32 by the guide portion. The guide portion is used to guide the main locking member 31 to move along a preset path, and the locking position and the unlocking position are both located on the preset path.
[0143] The guide portion includes a first guide bevel 311 and a second guide bevel 321 that abut against each other. The first guide bevel 311 is provided on the primary locking member 31, and the second guide bevel 321 is provided on the movable member 32. When the hatch 2 transitions from the first position to the second position, the toggle member 35 drives the movable member 32 to move, thereby causing the second guide bevel 321 to push the first guide bevel 311 to move, causing the primary locking member 31 to move from a locked position (locking the battery pack 9) to an unlocked position (unlocking the battery pack 9).
[0144] In one embodiment, the shifting member 35 is a shifting piece or a cam, and the moving member 32 is a push rod.
[0145] In another embodiment, the toggle member 35 can also be a gear, and the moving member 32 is a rack. The rack can be driven to move by the gear while the hinge shaft 4 is rotating with the gear.
[0146] In the embodiment shown in Figures 7 and 8, the moving member 32 is a push rod, the toggle member 35 is a paddle, and the moving member 32 is provided with a toggle groove 322. The toggle member 35 is located in the toggle groove 322. When the hinge shaft 4 drives the toggle member 35 to rotate clockwise, the toggle member 35 can push the side wall of the toggle groove 322, thereby moving the moving member 32.
[0147] Furthermore, a slot 312 is provided on the main locking member 31, and one end of the movable member 32 is inserted into the slot 312, so that the second guide bevel 321 at the bottom of the movable member 32 is fitted with the first guide bevel 311 on the main locking member 31 (as shown in Figure 8). When the hatch 2 is switched from the first position to the second position, the toggle member 35 drives the movable member 32 to move to the right (according to the orientation in Figure 8), so that the second guide bevel 321 pushes the first guide bevel 311 to the right. Since the main locking member 31 is limited to move along a predetermined path, in the embodiment shown in Figure 8, the predetermined path is roughly perpendicular to the moving direction of the movable member 32. Therefore, under the thrust of the second guide bevel 321, the main locking member 31 moves along the predetermined path to the unlocked position, that is, the main locking member 31 retracts downward from the locking groove of the battery pack 9, unlocking. battery pack 9, at this time the main locking member 31 squeezes the first elastic member 34, and the first elastic member 34 is in a charged state; when the hatch 2 moves from the second position to the first position, the toggle member 35 releases the moving member 32, and the moving member 32 no longer applies a thrust to the first guide slope 311. The main locking member 31 moves to the locked position under the elastic force of the first elastic member 34, that is, it extends upward into the locking groove of the battery pack 9 and locks the battery pack 9. At the same time, the movement of the main locking member 31 causes the first guide slope 311 to push the second guide slope 321, thereby resetting the moving member 32.
[0148] In one embodiment, as shown in Figures 1 to 4, the mounting body 1 includes a base 11, a bottom plate 13 and a protective shell 12. A cavity 14 is formed between the protective shell 12 and the base 11. The bottom plate 13 is in the cavity 14 and is installed on the base 11 for supporting the battery pack installed in the cavity 14.
[0149] Among them, the moving part 32 and the main locking part 31 are installed between the bottom plate 13 and the base 11. When the main locking part 31 moves from the unlocking position to the locking position, it can extend upward from the bottom plate 13 to lock the battery pack. An opening 131 for the main locking part 31 to extend is provided on the bottom plate 13, and when the main locking part 31 moves from the locking position to the unlocking position, it retracts downward from the bottom plate 13 to unlock the battery pack.
[0150] Optionally, a guide structure for guiding the movement of the moving member 32 is provided at the bottom of the base plate 13 . The guide structure may be a guide slot or a guide rib that cooperates with the slot provided on the moving member 32 .
[0151] The specific process of taking and placing the battery pack is described below based on the embodiments shown in Figures 9 to 12.
[0152] Figures 9 and 10 show the state of the locking mechanism 3 when the hatch 2 is in the first position. At this time, the main locking member 31 of the locking mechanism 3 is in the locked position, that is, it protrudes upward from the bottom plate 13 so as to be able to extend into the locking groove of the battery pack, thereby locking the battery pack in the cavity 14.
[0153] When the hatch 2 is rotated from the first position to the second position, the toggle member 35 pushes the moving member 32 to move as the hinge shaft 4 rotates, so that the second guide slope 321 of the moving member 32 pushes the first guide slope 311 of the main locking member 31, moving the main locking member 31 from the locked position to the unlocked position.
[0154] Figures 11 and 12 show the state of the locking mechanism 3 when the hatch 2 is in the second position. At this time, the main locking member 31 of the locking mechanism 3 is retracted to the bottom plate 31 (in the unlocked position), the battery pack is unlocked, and the battery pack can be removed from the opening of the cavity 14.
[0155] After the battery pack is charged and placed back into the cavity 14, the hatch 2 is flipped from the second position to the first position, and the toggle member 35 rotates with the hinge shaft 4 to release the movable member 32. At this time, the elastic force of the first elastic member 34 pushes the main locking member 31 upward, and the main locking member 31 moves to a locking position protruding from the bottom plate 13. At the same time, the first guide slope 311 of the main locking member 31 pushes the second guide slope 321 of the movable member 32, so that the movable member 32 is reset.
[0156] It will be understood by those skilled in the art that, in the technical solution provided by the present application, the locking mechanism is not limited to the structural form described in the above embodiment. In other embodiments, the locking mechanism may be coupled to the hatch 2 in an electronically controlled manner, so that when the hatch 2 is opened, the hatch 2 can drive the locking mechanism 3 to unlock the battery pack, wherein the locking mechanism includes:
[0157] A primary locking member having a locked position for locking the battery pack within the cavity 14 and an unlocked position for releasing the battery pack within the cavity 14;
[0158] A first detection assembly, connected to the mounting body 1 and used to detect the position of the hatch 2; and
[0159] The first control unit is provided in association with the main locking member and the first detection assembly. When the first detection assembly detects that the hatch 2 moves from the first position to the second position, the first control unit controls the main locking member to move from the locking position to the unlocking position.
[0160] In other embodiments, the locking mechanism 3 may be unlocked by the linkage mechanism instead of by the action of opening the hatch 2. Specifically, as shown in Figures 25-26, the movable member 32 of the linkage mechanism is hinged to the base plate 13 via a hinge shaft 4, wherein the hinge shaft 4 is located in the middle section of the movable member 32. One end of the movable member 32 is used to cooperate with the hatch 2 to keep the hatch 2 fastened to the base plate 13. The other end of the movable member 32 is used to cooperate with the main locking member 31 of the locking mechanism 3 to lock or unlock the battery pack 9. The hatch 2 includes a gripping portion 23 for the operator to grip to open the hatch. The user can unlock the locking mechanism 3 by moving the end of the movable member 32 that cooperates with the hatch 2. A preset distance is provided between the end that cooperates with the hatch 2 and the gripping portion 23. Alternatively, a separate unlocking mechanism can be provided on the grip portion 23 of the hatch 2. When the operator lifts the hatch 2 with one hand, the unlocking mechanism is simultaneously contacted, causing the unlocking mechanism to actuate the movable member 32, thereby driving the locking mechanism 3 to unlock the battery pack 9. This allows both opening the hatch and unlocking the battery pack 9 to be accomplished in one action. Alternatively, the locking mechanism 3 can be provided on the mounting body 1. A predetermined distance between the locking mechanism 3 and the hatch 2 allows the operator to contact the locking mechanism 3 with a finger or other part of the same hand as they attempt to lift the hatch with one hand.
[0161] More specifically, the locking mechanism 3 may be an unlocking button provided on the hatch cover gripping portion 23. The unlocking button may trigger other mechanical linkage or electronic linkage structures within the hatch cover 2, which is not specifically limited herein.
[0162] It should also be understood that, in the technical solution provided in this application, the hatch cover 2 is not limited to being mounted on the mounting body 1 by flipping. The hatch cover 2 can also be arranged to be installed so as to be translatably movable relative to the mounting body 1. For example, the hatch cover 2 can be translated between a first position and a second position via a linkage mechanism. When the hatch cover 2 moves from the first position to the second position relative to the mounting body 1, the linkage component can also be driven to operate, thereby driving the main locking member 31 to move to the unlocked position, thereby unlocking the battery pack. Similarly, when the hatch cover 2 moves from the second position to the first position, the elastic force of the spring can cause the main locking member 31 to move to the locked position, thereby locking the battery pack.
[0163] Furthermore, the electric device has a horizontal state and an upright state. Users often switch between these two states when using, transporting, or storing the device. The horizontal state generally refers to the device being ready for immediate operation. In this state, the device is typically placed horizontally on the ground. The upright state generally refers to the state when the hatch 2 is open, with the opening 15 of the device providing access to the battery pack facing downward. This downward orientation of the opening 15 should be understood as a state where the battery pack can easily escape from the opening 15 and out of its mounting position. Therefore, the downward orientation of the opening 15 includes both the opening 15 facing the ground and the opening 15 being at a certain angle to the ground, as long as the angle allows the battery pack to escape from its mounting position. For example, a push mower can be used to switch from a horizontal position on flat ground to an upright position with the push rod folded for storage. Alternatively, the push mower can be switched from a horizontal position on flat ground to a position on a steep slope. As shown in Figure 24, the electric device on the left is in a horizontal state, and the angle between the orientation of its opening 15 and the direction of gravity is A1. When A1 is greater than 90 degrees, it means that the orientation of the opening 15 is upward. When A1 is equal to 90 degrees, the opening of A1 is in a horizontal state; the electric device on the right is in an upright state, and the angle between the orientation of its opening 15 and the direction of gravity is A2. When A2 is between 60 and 90 degrees, the downward tilt angle of the opening 15 is smaller. When A2 is less than or equal to 60 degrees, the downward tilt angle of the opening 15 is larger, and the battery pack 9 can more easily detach from the installation position from the opening 15.
[0164] On the one hand, in order to prevent the user from accidentally unlocking the locking mechanism of the battery pack during the use, transportation and storage of the electric device, which will make the battery pack more likely to fall along the slide rail under the action of gravity. This embodiment provides an electric device, which includes a mounting body, a locking mechanism and an anti-detachment component. The mounting body is used to carry the battery pack, and the locking mechanism is used to lock the battery pack so that the battery pack is in the installation position or release the battery pack to allow the battery pack to be removed from the installation position. The anti-detachment component is configured to prevent the battery pack from detaching from the mounting body when the electric device is flipped from a horizontal state to a vertical state. Further, please refer to Figure 3. In this embodiment, the locking mechanism and the anti-detachment component are arranged side by side on the mounting surface of the mounting body in the direction perpendicular to the insertion direction of the battery pack.
[0165] In order to prevent the battery pack from falling off during the switching state of the electric device, this embodiment also provides an electric device, please refer to Figures 13 to 18, and Figure 24. The electric device includes a battery pack mounting structure and a battery pack 9 that provides energy. The electric device is provided with an opening 15 for assembling the battery pack 9. The orientation of the opening 15 has an angle A formed with the plane where the gravity direction is located. The battery pack mounting structure includes a mounting body 1, a locking mechanism 3 and an anti-detachment component 5. The mounting body 1 is used to carry the battery pack 9, and the locking mechanism 3 is used to lock the battery pack 9 so that the battery pack 9 remains in the installation position or release the battery pack 9 to allow the battery pack 9 to detach from the installation position. When the electric device is at least at an angle A less than or equal to 60 degrees, the anti-detachment component 5 is configured to prevent the battery pack 9 from detaching from the installation position. Specifically, taking a push lawn mower as an example, as shown in Figures 13 to 22, and Figure 24, the push lawn mower has a first posture of vertical storage placement and a second posture of horizontal placement on the ground. In the second posture, the angle A1 formed by the direction of the opening 15 and the plane where the gravity direction is located is in the range of 60-120 degrees. In the first posture, the angle A2 formed by the direction of the opening 15 and the plane where the gravity direction is located is in the range of 0-60 degrees.
[0166] Furthermore, it can be understood that when the battery pack 9 is in the installation position, it can be slightly shaken in the installation position. As long as the battery pack 9 remains electrically connected to the electrical connector on the electric device, when the battery pack 9 is out of the installation position, the battery pack 9 will be electrically disconnected from the electric device.
[0167] According to another aspect of the present application, an electric device is also provided, which includes a battery pack mounting structure and a battery pack that provides energy. When the electric device is placed horizontally on the ground, the center of gravity of the electric device has a distance H from the ground. During the process of the electric device being lifted or flipped to change its posture, the weight of the battery pack with a large capacity is usually heavier, and the risk of the battery pack slipping is higher. In order to solve this problem, the battery pack mounting structure includes a mounting body, a locking mechanism and an anti-slip assembly, wherein the mounting body is used to carry the battery pack, and the locking mechanism is used to lock the battery pack so that the battery pack remains in the installation position or release the battery pack to allow the battery pack to be removed from the installation position. When the electric tool is flipped around its center of gravity at a certain angle and the distance H from the ground changes, the anti-slip assembly is configured to prevent the battery pack from being removed from the installation position.
[0168] Specifically, the electric device is a push lawn mower. As shown in Figures 13 to 23, when the push lawn mower is horizontal, its center of gravity G is substantially below the battery pack 9. When the push lawn mower is in an upright position, the position of its center of gravity G changes. The center of gravity of the push lawn mower in the upright position is raised by a distance h1 compared to the horizontal position. At this time, the push lawn mower is in a transportable state. To make it more difficult for the operator to easily unlock the battery pack 9 and to more stably maintain the normal operation of the machine and the operator's safety, the push lawn mower includes a device body, a push rod portion connected to the device body, and a battery pack mounting structure connected to or integrally formed with the device body. When the ground clearance H is raised by a predetermined distance h1 in a direction perpendicular to the ground, the anti-detachment assembly 5 is automatically triggered to prevent the battery pack 9 from leaving the installation position, thereby more firmly maintaining the battery pack 9 in the installation position, thereby making the push lawn mower safer during transport or flipping. The center of gravity G here refers to the center of gravity when the battery pack 9 is installed.
[0169] In the above embodiment, the locking mechanism 3 and the anti-slip assembly 5 can both be used to lock the battery pack 9. When the electric device is in an upright position or is being shaken, the large-capacity battery pack 9 is typically heavier, increasing the risk of the battery pack 9 slipping out. Even if the operator does not trigger the unlocked state of the locking mechanism 3, the dual independent locking of the locking mechanism 3 and the anti-slip assembly 5 ensures a more secure locking of the battery pack mounting structure, making it safer to use. Furthermore, in this embodiment, opening the hatch 2 unlocks the locking mechanism 3. If the opening 15 for accessing the battery pack 9 is facing downward at this time, i.e., if the battery pack 15 is inserted in a downwardly tilted direction, the battery pack 15 may be dislodged from its mounting position due to gravity, potentially injuring the user's foot or causing damage to the battery pack. However, the anti-slip assembly 5 maintains the battery pack 9 in its mounted position even when the locking mechanism 3 is unlocked, preventing it from slipping out. This ensures a more secure locking of the battery pack mounting structure, making it safer to use.
[0170] As a specific embodiment, a push mower is used as an example of an electric tool. The push mower includes a main body, a push rod connected to the main body, and a wheel assembly that drives the main body forward. The battery pack mounting structure is connected to or integrally formed with the main body. During transportation or storage, or when the push mower is traveling uphill, the mower tilts at a significant angle. In this situation, the opening through which the user accesses the battery pack 9 is facing downward. Due to the heavy weight of the battery pack 9, typically weighing 5-10 kg, if the user accidentally or unintentionally opens the hatch 2, the battery pack 9 could be pulled out of the opening 15 of the cavity 14 under the force of gravity, potentially injuring the user's foot or damaging the battery pack 9 by knocking against it. This same issue can also occur with other battery pack mounting structures. For example, the user could simultaneously unlock the main locking member 31 while unlocking the hatch 2, or the main locking member 31 could already be unlocked before the hatch 2 opens the cavity 14 to allow the user to remove the battery pack 9. To prevent the battery pack 9 from falling out of the opening 15 when the opening 15 of the cavity 14 is facing downward, in some embodiments, the battery pack mounting structure may include an anti-falloff assembly 5. The anti-falloff assembly 5 is configured to prevent the battery pack 9 from falling out of the opening 15 when the battery pack mounting structure is in an upright position with the opening 15 of the cavity 14 facing downward. It is understood that the electric device may also be other garden power tools, such as a chain saw, a lawn mower, a hedge trimmer, a hair dryer, etc.
[0171] Specifically, the anti-slip assembly includes an auxiliary locking member and a retaining member. The auxiliary locking member is configured to be able to switch between an unlocked position for releasing the battery pack and a locked position for locking the battery pack. The retaining member is configured to keep the auxiliary locking member in the locked position at all times when the electric device is flipped from the horizontal state to the upright state, so that the auxiliary locking member can lock or unlock the battery pack by only controlling the retaining member. The structure is simple and reliable.
[0172] In one embodiment, when the electric device is in an upright position, the retaining member is coupled to the auxiliary locking member and prevents the auxiliary locking member from moving from the locked position to the unlocked position; when the electric device is in a horizontal position, the retaining member is disengaged from the auxiliary locking member, and the auxiliary locking member can freely switch between the locked position and the unlocked position. As shown in Figures 17 and 22, the anti-detachment assembly 5 includes an auxiliary locking member 51 and a retaining member 53; wherein the auxiliary locking member 51 is configured to be able to switch between a third position and a fourth position, the third position being a locked position, in which the auxiliary locking member 51 extends into the card slot of the battery pack 9 in the cavity 14 to lock the battery pack, and the fourth position being an unlocked position, in which the auxiliary locking member 51 releases the battery pack 9.
[0173] The retaining member 53 is configured to be switchable between a fifth position and a sixth position. When the retaining member 53 is in the fifth position, it can retain the auxiliary locking member 51 at the third position. When in the sixth position, the retaining member 53 releases the auxiliary locking member 51 .
[0174] When the battery pack mounting structure is in an upright state, the retaining member 53 is switched to the fifth position. When the battery pack mounting structure is switched to a horizontal state with the opening 15 of the cavity 14 facing upward, the retaining member 53 is switched to the sixth position.
[0175] Furthermore, the anti-detachment component 5 also includes a second elastic member 52, and the auxiliary locking member 51 is configured to be able to extend into the card slot of the battery pack 9 under the elastic force of the second elastic member 52. When the auxiliary locking member 51 releases the battery pack 9, the battery pack 9 can overcome the elastic force of the second elastic member 52 during movement and push the auxiliary locking member 51 to the fourth position.
[0176] Preferably, when the electric device is in an upright state and a horizontal state respectively, the retaining member relies on gravity to couple and disengage with the auxiliary locking member respectively. Specifically, the retaining member 53 is set to be rotatable; when the battery pack mounting structure is in a first posture, that is, an upright state, the retaining member 53 automatically rotates under the action of gravity to rest on the auxiliary locking member 51 and is in the fifth position, thereby maintaining the auxiliary locking member 51 in the third position, and the auxiliary locking member 51 can lock the battery pack 9 in the cavity 14; when the battery pack mounting structure is converted to a second posture, that is, a horizontal state, the retaining member 53 automatically rotates to the sixth position under the action of gravity, and the retaining member 53 releases the auxiliary locking member 51. The auxiliary locking member 51 can be squeezed back to the fourth position by the battery pack 9 when the battery pack 9 moves outward to release the battery pack 9.
[0177] Specifically, as shown in Figures 13 to 15, when the auxiliary locking piece 51 is in the third position, it protrudes upward from the bottom plate 13, so that it can extend into the card slot of the battery pack 9 located in the cavity 14. When the battery pack 9 is taken out, the battery pack 9 moves outward to squeeze the auxiliary locking piece 51, causing the auxiliary locking piece 51 to retract downward to the fourth position.
[0178] The specific installation of the anti-slip component 5 can refer to Figures 17-18 and Figures 21-22.
[0179] The auxiliary locking member 51 is movably mounted on a mounting seat 54 below the base plate 13. A second elastic member 52 is arranged between the mounting seat 54 and the auxiliary locking member 51. Under the elastic force of the second elastic member 52, the auxiliary locking member 51 protrudes upward from the base plate 13, thereby being in the third position.
[0180] The auxiliary locking member 51 has one end protruding upward from the bottom plate 13 and has a first inclined surface 511 and a second inclined surface 512. The first inclined surface 511 is located on the side of the auxiliary locking member 51 facing the opening 15 of the cavity 14, and the second inclined surface 512 is located on the side of the auxiliary locking member 51 facing away from the opening 15 of the cavity 14. Thus, when the battery pack 9 is removed from the cavity 14, the battery pack 9 presses the auxiliary locking member 51 along the second inclined surface 512, causing the auxiliary locking member 51 to retract downward to the fourth position. When the battery pack 9 is returned to the cavity 14, the battery pack 9 presses the auxiliary locking member 51 along the first inclined surface 511, causing it to retract downward to the fourth position. When the battery pack 9 moves to the point where the auxiliary locking member 51 aligns with the battery pack 9's slot, the auxiliary locking member 51 pops out and enters the battery pack 9's slot. At this point, the auxiliary locking member 51 is in the third position.
[0181] The retaining member 53 is configured to be rotatably mounted on the base 11 or the mounting seat 54 via a rotating shaft 531, and the center of gravity of the retaining member 53 is configured to be away from the rotating shaft 531, so that the retaining member 53 can automatically rotate between the fifth position and the sixth position under the action of gravity according to the posture of the installation structure of the cavity 14.
[0182] When the battery pack mounting structure is in a horizontal state with the opening 15 of the cavity 14 facing upward, for example, a lawn mower having the battery pack mounting structure is in a horizontal state (as shown in FIG16 ), the retaining member 53 rotates to the sixth position under the action of gravity and remains in the sixth position, as shown in FIG17 and FIG18 . At this time, the retaining member 53 will not affect the movement of the auxiliary locking member 51.
[0183] When the battery pack mounting structure is in an upright state with the opening 15 of the cavity 14 facing downward, for example, a lawn mower having the battery pack mounting structure is in an upright state (as shown in FIG19 ), the retaining member 53 rotates to the sixth position under the action of gravity. At this time, the retaining member 53 rotates under the action of gravity to rest on the auxiliary locking member 51 and is in the fifth position.
[0184] The auxiliary locking member 51 is provided with a stopper 513. Referring to Figures 18 and 88, when the retaining member 53 rests on the auxiliary locking member 51, it cooperates with the stopper 513 to prevent the auxiliary locking member 51 from moving from the third position to the fourth position, thereby locking the battery pack. That is, when the battery pack mounting structure is in a downwardly facing position with the opening 15 of the cavity 14 and the hatch 2 is open, as shown in Figures 20 to 22, the auxiliary locking member 51 is in the third position, locking the battery pack 9. The auxiliary locking member 51 prevents the battery pack 9 from falling out of the cavity 14.
[0185] It is understandable that the anti-slip component 5 is not limited to the structural form described above. In other embodiments, the anti-slip component 5 can also be in the form of electronic control.
[0186] Specifically, in one embodiment, the anti-slip component may include:
[0187] an auxiliary locking member, the auxiliary locking member being configured to be movable between a third position and a fourth position, wherein in the third position, the auxiliary locking member extends into the card slot of the battery pack in the cavity to lock the battery pack, and in the fourth position, the auxiliary locking member releases the battery pack;
[0188] A first detection component, configured to detect whether the battery pack mounting structure is in a first posture; and
[0189] The second control unit is associated with the auxiliary locking member and the first detection component. When the first detection component detects that the battery pack installation structure is in the first posture, the second control unit controls the auxiliary locking member to move to the third position.
[0190] In order to prevent the battery pack 9 from escaping from the opening 15 when the opening 15 of the cavity 14 faces downward, other methods may be used.
[0191] For example, in one embodiment, the battery pack mounting structure further includes: a retaining member, the retaining member being configured to be movable between a seventh position and an eighth position;
[0192] In the seventh position, the retaining element is able to retain the primary locking element 31 in the locked position, and in the eighth position, the retaining element releases the primary locking element 31 .
[0193] After the main locking member 31 is released by the retaining member, it can move to the unlocked position when the hatch 2 is opened to the second position as described above, and can move to the locked position when the hatch 2 is moved to the first position.
[0194] Among them, when the battery pack mounting structure is in an upright state with the opening 15 of the cavity 14 facing downward, the retaining member is converted to the seventh position, and when the battery pack mounting structure is converted to a horizontal state with the opening of the cavity facing upward, the retaining member is converted to the eighth position.
[0195] Among them, the setting method of the retaining member in this embodiment can be the same as the setting method of the retaining member 53 for retaining the auxiliary locking member 51 as described above. When the battery pack mounting structure is in an upright state, the retaining member can be set to be able to rotate to abut against the main locking member 31 and maintain the main locking member 31 in a locked position, so that the main locking member 31 maintains the state of locking the battery pack and prevents the hatch 2 from being opened in the upright state.
[0196] In addition, in one embodiment, the battery pack installation structure may further include a spring member. This spring member may be configured similarly to the auxiliary locking member 51 described above. Under the elastic force of the elastic member, it can protrude upward from the bottom plate 13 to engage the battery pack 9, and can retract downward under the pressure of the battery pack 9. Thus, when the battery pack 8 is placed into the cavity 14, the battery pack 9 pushes on the spring member, causing it to retract downward. As the battery pack 9 continues to move into the cavity 14, the spring member aligns with the engaging slot of the battery pack 9, and then it pops out again under the action of the elastic member. This process produces a "click" sound, which can be used to detect whether the battery pack 9 is properly installed.
[0197] It is understandable that in the embodiment provided with the auxiliary locking member 51 , when the battery pack 9 is installed into the cavity 14 , the auxiliary locking member 51 will also produce a “click” sound. In this case, the spring member may not be provided.
[0198] In addition, in the embodiment provided in the present application, the hatch cover 2 needs to be connected with the installation body 1 when closing the cavity 14, and there can be multiple ways of connecting the hatch cover 2 with the installation body 1.
[0199] In one embodiment, as shown in FIG3 and FIG4 , the base 11 is provided with support walls 111 on opposite sides of the opening 15 of the cavity 14 , and the hatch 2 is configured to be able to be buckled onto the support walls 111 ;
[0200] The upper portion of the support wall 111 serves as a guide for guiding the fastening of the hatch cover 2. When pressed, the hatch cover 2 snaps onto the support wall 111. Specifically, the guide portion above the support wall 111 gradually tilts outward from top to bottom. This creates a large gap between the hatch cover 2 and the guide portion when it first contacts it. As the hatch cover 2 tilts downward, the gap gradually decreases, forming an interference fit with the hatch cover 2. Pressing the hatch cover 2 slightly deforms it against the support wall, causing it to open. Continued pressure causes the hatch cover 2 to snap onto the support wall 111.
[0201] In one embodiment, a magnetic component may be further provided between the hatch cover 2 and the installation body 1. When the hatch cover 2 is in the position of closing the cavity 14, the magnetic component is adsorbed on the installation body 1, so that the hatch cover 2 is fixed.
[0202] When opening the hatch cover 2, the operator can manually push the hatch cover 2 to flip or translate it to open the cavity 14. In other embodiments, a drive mechanism can be provided between the hatch cover 2 and the mounting body 1, and a control component can be provided on the electric device on which the battery pack mounting structure is installed. For example, a control component (such as an operating button) can be provided at a convenient handle position or other position on the electric device. When the hatch cover 2 is to be opened, the control component can be used to control the drive mechanism to open the hatch cover 2.
[0203] In addition, a locking mechanism may be provided between the hatch cover 2 and the installation body 1 , and when the hatch cover 2 closes the cavity, the hatch cover 2 may be locked to the installation body 1 through the locking mechanism.
[0204] In the solution provided in this application, a retaining mechanism may be provided between the hatch 2 and the mounting body 1 to facilitate access to the battery pack. When the hatch 2 is in the second position, the retaining mechanism holds the hatch 2 in the second position, eliminating the need to hold the hatch 2, making it easier to access the battery pack. Alternatively, the retaining mechanism may be a cylinder. When the hatch 2 is flipped open, the cylinder extends and supports the hatch 2, maintaining it in the open position. When the hatch 2 is flipped closed, the cylinder retracts.
[0205] According to another aspect of the present application, a battery pack mounting structure is further provided, comprising:
[0206] The mounting body 1 is formed with a cavity 14 having an opening 15 , and the cavity 14 is used to accommodate the battery pack 9 ;
[0207] a hatch 2 movably mounted on the mounting body 1 , the hatch 2 having a first position for cooperating with the mounting body 1 to close the cavity 14 , and a second position for opening the cavity 14 to provide access to the battery pack 9 ;
[0208] A locking mechanism 3 for locking or releasing the battery pack 9; and
[0209] The anti-detachment component 5 can prevent the battery pack 9 from escaping from the opening 15 when the locking mechanism releases the battery pack 9 and the battery pack mounting structure is in an upright state with the opening 15 of the cavity 14 facing downward.
[0210] In one embodiment, the anti-slip assembly 5 includes an auxiliary locking member 51 and a retaining member 53; wherein,
[0211] The auxiliary locking member 51 is configured to be convertible between a third position and a fourth position. In the third position, the auxiliary locking member 51 extends into the card slot of the battery pack 9 in the cavity 14 to lock the battery pack 9. In the fourth position, the auxiliary locking member 51 releases the battery pack 9.
[0212] The retaining member 53 is configured to be switchable between a fifth position and a sixth position. When the retaining member 53 is in the fifth position, it can retain the auxiliary locking member 51 at the third position. When in the sixth position, the retaining member 53 releases the auxiliary locking member 51 .
[0213] When the battery pack mounting structure is in an upright state, the retaining member 53 is switched to the fifth position. When the battery pack mounting structure is switched to a horizontal state with the opening 15 of the cavity 14 facing upward, the retaining member 53 is switched to the sixth position.
[0214] Furthermore, the anti-detachment component 5 also includes a second elastic member 52, and the auxiliary locking member 51 is configured to be able to extend into the card slot of the battery pack 9 under the elastic force of the second elastic member 52. When the auxiliary locking member 51 releases the battery pack 9, the battery pack 9 can overcome the elastic force of the second elastic member 52 during movement and push the auxiliary locking member 51 to the fourth position.
[0215] In one embodiment, the retaining member 53 is configured to be rotatable; when the battery pack mounting structure is in an upright state, the retaining member 53 automatically rotates under the action of gravity to rest on the auxiliary locking member 51 and is in the fifth position, thereby maintaining the auxiliary locking member 51 in the third position, and the auxiliary locking member 51 can lock the battery pack 9 in the cavity; when the battery pack mounting structure is converted to a horizontal state, the retaining member 53 automatically rotates to the sixth position under the action of gravity, and the retaining member 53 releases the auxiliary locking member 51. The auxiliary locking member 51 can be squeezed back to the fourth position by the battery pack 9 when the battery pack 9 moves outward to release the battery pack 9.
[0216] In another embodiment, the anti-slip component 5 can also be in the form of electronic control. Specifically, the anti-slip component 5 may include:
[0217] an auxiliary locking member, the auxiliary locking member being configured to be movable between a third position and a fourth position, wherein in the third position, the auxiliary locking member extends into the card slot of the battery pack in the cavity to lock the battery pack, and in the fourth position, the auxiliary locking member releases the battery pack;
[0218] A first detection component, configured to detect whether the battery pack mounting structure is in a first posture; and
[0219] The second control unit is associated with the auxiliary locking member and the first detection component. When the first detection component detects that the battery pack installation structure is in the first posture, the second control unit controls the auxiliary locking member to move to the third position.
[0220] In order to prevent the battery pack 9 from escaping from the opening 15 when the opening 15 of the cavity 14 faces downward, other methods may be used.
[0221] For example, in one embodiment, the locking mechanism 3 includes: a main locking member 31 and a linkage assembly;
[0222] The main locking member 31 has a locked position for locking the battery pack 9 within the cavity 14 and an unlocked position for releasing the battery pack 9 within the cavity 14. A linkage assembly is connected to the hatch 14 and is capable of actuating the main locking member 31. When the hatch 2 moves from the first position to the second position, the linkage assembly drives the main locking member 31 from the locked position to the unlocked position.
[0223] The anti-slip assembly 5 includes: a retaining member, which is configured to be able to move between a seventh position and an eighth position; in the seventh position, the retaining member can maintain the main locking member 31 in the locked position to prevent the battery pack 9 from escaping from the opening 15, and in the eighth position, the retaining member releases the main locking member 31; wherein, when the battery pack mounting structure is in an upright state with the opening 15 of the cavity 14 facing downward, the retaining member is converted to the seventh position, and when the battery pack mounting structure is converted to a horizontal state with the opening 15 of the cavity 14 facing upward, the retaining member is converted to the eighth position.
[0224] In addition to the electric device provided by the present application, the present application also provides a method for disassembling a battery pack based on the above battery pack mounting structure, the method comprising:
[0225] Step S1: Open the hatch cover and move the hatch cover from a first position to a second position, so that the hatch cover triggers a locking mechanism to unlock the battery pack in the cavity;
[0226] Step S2: Take out the battery pack in the cavity.
[0227] Using this method, when the user unlocks the battery, the locking mechanism can be driven to unlock the battery pack simply by opening the hatch. The user no longer needs to trigger the unlock button of the battery pack by hand. The operation is simple and convenient, and the usability is improved.
[0228] Since most hatches have a hatch locking structure, the user further includes step S0 before using the battery pack disassembly method. Step S0 is to unlock the hatch of the battery pack so that the hatch can be relatively separated from the installation body.
[0229] Furthermore, in order to reduce the need for the user to unlock the battery pack hatch, while at the same time locking the hatch to the mounting body, the hatch can be buckled onto the mounting body with a predetermined force. This allows the user to open the battery pack hatch with a predetermined force, which not only locks the hatch and the mounting body together but also facilitates the user's opening of the battery pack hatch. In the embodiment provided herein, the hatch and the mounting body are magnetically attracted to each other. Accordingly, step S0 is: opening the battery pack hatch with a predetermined force, so that the hatch can be relatively separated from the mounting body. It is understood that in other embodiments, the hatch and the mounting body can also be connected by the principle of elastic deformation of the hatch or the mounting body, using the elastic force generated by the elastic deformation to provide the adsorption force between the hatch and the mounting body, and no specific limitation is imposed herein.
[0230] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
