Description

Technical Field

[0001] The utility model relates to the technical field related to electric tools, and in particular to a flip structure for electric tools and the electric tool. Background Art

[0002] Electric tools such as lawn mowers and sweepers usually include multiple compartments with covers, such as a battery compartment, a tool compartment of a lawn mower, a garbage storage compartment of a sweeper, etc. The cover is flipped and set on the electric tool to prevent it from falling off, and it is easy to open and close. Taking the battery compartment as an example, electric tools are usually equipped with a mobile power supply. Under some working conditions, in order to maintain long-term work, it is necessary to use battery replacement to quickly replenish energy. The electric tool needs to be provided with a battery compartment for accommodating the mobile power supply. The battery compartment includes a compartment body for accommodating the battery and a compartment cover connected to the compartment body. The battery replacement is completed by opening and closing the compartment cover. For example, in the Chinese patent literature, a lawn mower and a covering device that can be applied to a lawn mower are authorized and announced on March 26, 2019 with the authorization announcement number CN 208638996U. The cover device includes a cover, a main body, and a battery pack plug interface that allows the battery pack to be detachably connected. The cover has a cover position in which the cover is in an engaged state with the main body and a flip position for inserting the battery pack into or removing it from the main body. The cover includes a cover portion and a rotating clamp connected to the cover portion. The main body is formed with a slot for accommodating the rotating clamp. The rotating clamp is pivoted in the slot and can be operated to rotate relative to the main body. In this application, the rotation point of the cover relative to the main body is the pivot point of the rotating clamp and the slot. The position of the pivot point of the rotating clamp and the slot remains unchanged. During the flipping of the cover, in order to maintain the reliability of the rotation of the cover and the main body, a large avoidance space needs to be reserved between the cover and the main body so that the cover does not interfere with the main body during the flipping process. This has a greater impact on products with high appearance requirements and affects the surface integrity of the electric equipment.

[0003] In addition, the closing of the bin cover in the prior art is completely dependent on the force exerted on the bin cover by human hands. There is a lack of resetting force during the resetting process of the bin cover. After the bin cover is closed, it cannot be ensured that it is firmly buckled on the bin body. It is possible that the closing force is small, resulting in the bin cover not being closed tightly, causing foreign matter to invade the interior of the electric equipment, causing abnormal conditions such as short circuits, and posing a safety hazard. Utility Model Content

[0004] In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a flip structure for an electric tool and an electric tool, which can ensure the surface integrity of the electric device without setting a special avoidance space.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A flip structure for an electric tool is used to rotatably connect two separate parts of the electric tool. The flip structure includes a first frame, a second frame, a first swing arm and a second swing arm. The first frame is connected to the inner side of one of the separate parts, and the second frame is connected to the inner side of the other separate part. The first swing arm and the second swing arm are cross-hinged. The first swing arm is rotatably connected to the second frame, and the second swing arm is rotatably connected to the first frame. A first slide groove is provided in the first frame to connect to the first swing arm and limit the sliding stroke of the first swing arm, and a second slide groove is provided in the second frame to connect to the second swing arm and limit the sliding stroke of the second swing arm.

[0007] The flip structure of the present application is applied to two split parts of an electric device. The two split parts are hinged by installing the flip structure of the present application. When flipping one of the split parts, the first swing rod and the second swing rod inside the flip structure rotate crosswise, the first swing rod rotates relative to the second frame, the second swing rod rotates relative to the first frame, the first swing rod slides in the first slide groove, and the second swing rod slides in the second slide groove. The cross rotation of the first swing rod and the second swing rod realizes the position avoidance of the two split parts when flipping. The intersection of the first swing rod and the second swing rod serves as the fulcrum for the rotation of the two split parts. It also rotates when the two split parts flip, and the avoidance is automatically realized. Therefore, there is no need to set up a special avoidance space. The flip structure adopts the cross rotation of the first swing rod and the second swing rod, and the lateral space occupied by the rod is small, which is conducive to the overall integration of the flip structure. By connecting the first frame and the second frame respectively on the inner side of the two split parts, the flip structure is hidden inside the electric device, and the structural integrity of the outer surface of the electric device is high, which can improve the surface performance of the electric device.

[0008] Preferably, the flip structure is provided with an elastic reset member, and when the split part is flipped open, the flip structure opens to pressurize the elastic reset member, thereby providing a reset force for the split part. When the split part is flipped open, the elastic reset member is squeezed, providing a reset force for the closure of the split part. The split part quickly flips and closes under the action of the elastic force, and the replacement efficiency of the internal parts of the electric device is improved; in addition, the split part is acted upon by the thrust of the elastic reset member, and has an initial velocity. Under the action of inertia, the split part can be tightly fastened to the bin body, reducing the occurrence of foreign matter entering the bin of the electric tool due to the loose closure of the split part.

[0009] Preferably, the first swing rod has a first avoidance groove, the second swing rod is connected to the first frame by setting a second rotating member, the first swing rod and the second swing rod swing crosswise when the flip structure is opened, and the first avoidance groove avoids the second rotating member; and / or, the second swing rod has a second avoidance groove, the first swing rod is connected to the second frame by setting a first rotating member, the first swing rod and the second swing rod swing crosswise when the flip structure is opened, and the second avoidance groove avoids the first rotating member. In this scheme, during the opening process of the flip structure, the second swing rod drives the second rotating member to approach the first swing rod along a predetermined path and finally moves into the first avoidance groove, the second swing rod will eventually be hindered by the first swing rod and cannot continue to move, the setting of the first avoidance groove expands the rotation range of the second swing rod relative to the first swing rod, and expands the opening and closing range of the flip structure; similarly, the second avoidance groove on the second swing rod is used to avoid the first rotating member on the first swing rod, and expands the rotation range of the first swing rod relative to the second swing rod.

[0010] Preferably, the first swing arm is a curved rod that is bent and convex toward the hinge of the first swing arm and the second swing arm, and the second swing arm is a curved rod that is bent and convex toward the hinge of the first swing arm and the second swing arm. When the split parts are opened, the second frame body flips relative to the first frame body along the bending direction of the curved rod, and the positions of the first frame body and the second frame body are close to each other. The positions of the two split parts are close to each other, and the integration is good, avoiding a large gap between the two split parts.

[0011] Preferably, the first swing arm comprises a first long rod and a first short rod connected to each other, the length of the first long rod is greater than the length of the first short rod, the first long rod is connected to the first slide slot, and the first short rod is connected to the second frame; the second swing arm comprises a second long rod and a second short rod connected to each other, the length of the second long rod is greater than the length of the second short rod, the second long rod is connected to the second slide slot, and the second short rod is connected to the first frame. The length of the first long rod is adapted to the length of the first slide slot, the length of the second long rod is adapted to the length of the second slide slot, the first short rod and the second short rod are respectively connected to the second frame and the first frame at a relatively short distance, and the overall structure of the first swing arm and the second swing arm is compact, reducing the occupied space.

[0012] Preferably, a first receiving groove with an opening is provided on the first frame, and a second receiving groove with an opening is provided on the second frame. The openings of the first receiving groove and the second receiving groove are arranged opposite to each other and are combined to form a receiving space for receiving the first swing rod and the second swing rod. The first swing rod and the second swing rod are limited to move in the receiving space, which reduces the possibility of external interference during the movement of the first swing rod and the second swing rod. In addition, the relatively closed receiving space protects the first swing rod and the second swing rod, and reduces the possibility of foreign matter intrusion.

[0013] Preferably, a clearance opening connected to the accommodation space is provided on the first frame and the second frame, and the clearance opening avoids the first swing arm and the second swing arm. During the movement of the first swing arm and the second swing arm, the hinge between the two tends to move outward relative to the accommodation space, and the first swing arm and the second swing arm can smoothly pass through the clearance opening to avoid interference with the first swing arm and the second swing arm by the inner wall of the accommodation space.

[0014] Preferably, the first slide groove and the second slide groove are both waist-shaped holes, and the first swing rod and the second swing rod are both provided with sliding shafts, which are confined in the waist-shaped holes. The sliding shaft and the waist-shaped hole slide in cooperation with each other, and the waist-shaped hole limits the travel range of the sliding shaft, but does not limit the rotation of the sliding shaft. The semicircular groove at the end of the waist-shaped hole stably cooperates with the sliding shaft, and the sliding shaft is more stably positioned in the semicircular groove.

[0015] Preferably, a rotation damper is provided between the first swing arm and the second swing arm, which can effectively reduce the noise generated when the product is used and make the split parts more smooth when flipping.

[0016] An electric tool comprises a bin cover, a bin body and the above-mentioned flip structure, wherein the flip structure connects the bin cover and the bin body so that the bin cover can be flipped open relative to the bin body. The electric tool has all the beneficial effects of the above-mentioned flip structure.

[0036] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0037] In the description of this embodiment, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore, cannot be understood as a limitation on the utility model. In addition, if the terms "first", "second", and "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0038] The flip structure of the electric tool provided in one embodiment of the utility model is as follows: Figures 1 to 8 As shown, two split parts 90 for rotatably connecting the electric tool, the flip structure includes a first frame 1, a second frame 2, a first rocker arm 3 and a second rocker arm 4, the first rocker arm 3 and the second rocker arm 4 are cross-hinged, the first frame 1 is connected to the inner side of one of the split parts 90, the second frame 2 is connected to the inner side of the other split part 90, the first rocker arm 3 is rotatably connected to the second frame 2, the second rocker arm 4 is rotatably connected to the first frame 1, a first slide groove 101 is provided in the first frame 1 to connect to the first rocker arm 3 and limit the sliding stroke of the first rocker arm 3, and a second slide groove 201 is provided in the second frame 2 to connect to the second rocker arm 4 and limit the sliding stroke of the second rocker arm 4.

[0039] The two separate parts of the electric device can be a motor compartment body and a motor compartment cover, a battery compartment body and a battery compartment cover, or two other parts connected by flipping, etc. Taking the battery compartment body and the compartment cover as an example, the compartment body 9 and the compartment cover 10 of the electric device are hingedly opened and closed by installing the flip structure of the present application, and the compartment cover 10 is flipped to open the compartment body of the electric tool. The first swing arm 3 and the second swing arm 4 inside the flip structure rotate crosswise, the first swing arm 3 rotates relative to the second frame 2, and the second swing arm 4 rotates relative to the first frame 1. The first swing arm 3 slides in the first slide groove 101, and the second swing arm 4 slides in the second slide groove 201. Through the first swing arm 3 and the second swing arm 4 Cross rotation, when the bin cover 10 is opened, the first swing arm 3 and the second swing arm 4 have three rotation fulcrums, which are the rotation points of the first swing arm 3 and the second frame 2, the rotation points of the second swing arm 4 and the first frame 1, and the rotation points of the first swing arm 3 and the second swing arm 4. Due to the limitation of the two sliding positions, the three rotation fulcrums will play a dynamic overall rotation as the bin cover 10 is flipped open, automatically avoiding the bin cover 10 and the bin body 9, and there is no need to dig a groove between the bin body 9 and the bin cover 10 to set up an avoidance space. The flip structure adopts the cross rotation of the first swing arm 3 and the second swing arm 4, and the lateral space occupied by the rod is small, which is conducive to the overall integration of the flip structure. By connecting the first frame 1 and the second frame 2 on the inner side of the bin body 9 and the bin cover 10 respectively, the flip structure is hidden inside the space formed by the combination of the bin body and the bin cover, and the structural integrity of the outer surface of the electric device is high, which can improve the surface performance of the electric device.

[0040] Furthermore, the flip structure is provided with an elastic reset member 5, which is compressed when the flip structure is opened and provides a reset force for closing the flip structure. Figure 5 and Figure 6In the example shown, the elastic return member 5 is a spring, and a first spring groove 105 corresponding to the spring is provided on the outer side of the first frame 1. The first spring groove 105 is coplanar with the first slide groove 101, and the length of the first spring groove 105 is greater than the length of the first slide groove 101. The first swing arm slides along the first slide groove 101 and acts on the spring in the first spring groove 105 at the same time. The second frame 2 is provided with a second spring groove 205 corresponding to the spring on the outer side, and the second spring groove 205 is coplanar with the second slide groove, and the length of the second spring groove 205 is greater than the length of the second slide groove. The second swing arm slides along the second slide groove 201 and acts on the spring in the second spring groove 205 at the same time. The two elastic return members 5 provide restoring force for the closure of the split parts after being compressed; in addition, the split parts are acted upon by the thrust of the elastic return members, and when they are fastened together at a certain speed, the split parts can be tightly fastened under the action of inertia, thereby reducing the occurrence of foreign objects entering the electric device due to loose closure; finally, the first slide groove 101 and the second slide groove 201 respectively limit the sliding stroke of the first rocker arm 3 and the second rocker arm 4, and the length of the first slide groove 101 and the second slide groove 201 jointly limit the maximum opening and closing angle between the first rocker arm 3 and the second rocker arm 4. Designers can flexibly design the lengths of the first slide groove 101 and the second slide groove 201 according to needs to adjust the opening and closing range of the hinge mechanism.

[0041] As a simple replacement for the above solution, the first sliding groove and the first spring groove can be integrated into one groove, and the second sliding groove and the second spring groove can be integrated into one groove.

[0042] As a simple replacement for the above solution, the elastic reset member 5 is a torsion spring arranged on the hinge axis of the first rocker arm and the second rocker arm.

[0043] In other embodiments of the present application, when the elastic return member is a spring, it is only arranged in the first slide groove 101 or the second slide groove 201, which can also achieve the elastic return effect of the split component.

[0044] Please refer to Figure 4 The first frame 1 and the second frame 2 are arranged opposite to each other, the first rocker arm 3 and the second rocker arm 4 are cross-placed between the first frame 1 and the second frame 2, a hinge hole 8 is opened at the position where the first rocker arm 3 and the second rocker arm 4 intersect each other, and a hinge shaft 7 is inserted into the hinge hole 8 to connect the first rocker arm 3 and the second rocker arm 4, and the first rocker arm 3 and the second rocker arm 4 can rotate relative to each other around the hinge shaft 7.

[0045] The first swing rod 3 is provided with a first rotation axis 302, and the second frame 2 is provided with a second rotation hole 203 at a position corresponding to the first rotation axis 302, and the first rotation axis 302 is inserted into the second rotation hole 203 and rotates; the second swing rod 4 is provided with a second rotation axis 402, and the first frame 1 is provided with a first rotation hole 103 at a position corresponding to the second rotation axis 402, and the second rotation axis 402 is inserted into the first rotation hole 103 and rotates. The above structure realizes the rotation connection by using the hole-axis matching relationship, and in other embodiments of the present application, the rotation connection relationship can also be realized by using bearings.

[0046] The flip structure of the electric tool provided in one embodiment of the utility model is as follows: Figure 7 As shown, it includes a first frame body 1 and a second frame body 2 that are arranged opposite to each other, a first receiving groove 104 with an opening is opened on the first frame body 1, and a second receiving groove 204 with an opening is opened on the second frame body 2, the openings of the first receiving groove 104 and the second receiving groove 204 are arranged opposite to each other and combined to form a receiving space for receiving the first swing arm 3 and the second swing arm 4, a first air avoidance opening 102 connected to the receiving space is opened on the first frame body 1, and a second air avoidance opening 202 connected to the receiving space is opened on the second frame body 2.

[0047] The first avoidance opening 102 and the second avoidance opening 202 are used to avoid the first swing arm 3 and the second swing arm 4. During the movement of the first swing arm 3 and the second swing arm 4, the hinges of the two tend to move outward relative to the accommodating space, and the first swing arm 3 and the second swing arm 4 can smoothly pass through the first avoidance opening 102 and the second avoidance opening 202, thereby avoiding the inner wall of the accommodating space from interfering with the first swing arm 3 and the second swing arm 4. The first swing arm 3 and the second swing arm 4 are confined to move within the accommodating space, reducing the possibility of external interference during the movement of the first swing arm 3 and the second swing arm 4. In addition, the relatively closed accommodating space protects the first swing arm 3 and the second swing arm 4, reducing the possibility of external foreign matter intrusion.

[0048] Furthermore, the first accommodating groove 104 and the second accommodating groove 204 are both U-shaped grooves, and the openings of the two U-shaped grooves are arranged opposite to each other. Since the U-shaped groove structure is relatively simple and the processing and manufacturing cost is low, it is convenient to mass produce it as a standardized part.

[0049] As a simple replacement for the above solution, the first frame 1 and the second frame 2 include two relatively spaced support plates, and the first rocker arm 3 and the second rocker arm 4 are accommodated in the space formed between the two support plates, which also has the effect of avoiding interference between the first rocker arm 3 and the second rocker arm 4.

[0050] like Figure 4As shown, the first frame 1 is provided with a first slide groove 101, and the first swing rod 3 is provided with a first sliding shaft 303, the first sliding shaft 303 is provided in the first slide groove 101 and slides therein, and the first slide groove 101 limits the sliding stroke of the first sliding shaft 303; the second frame 2 is provided with a second slide groove 201, and the second swing rod 4 is provided with a second sliding shaft 403, the second sliding shaft 403 is provided in the second slide groove 201 and slides therein. The lengths of the first slide groove 101 and the second slide groove 201 jointly define the maximum opening and closing angle between the first swing rod 3 and the second swing rod 4. The elastic reset member is provided in the first slide groove 101 and abuts against the first sliding shaft 303, and the elastic reset member is provided in the second slide groove 201 and grounded against the second sliding shaft 403, and the elastic reset member provides a reset thrust for the first sliding shaft 303 and the second sliding shaft 403. In this embodiment, the elastic reset member is a spring, and in other embodiments of the present application, the spring can also be replaced by a rubber spring, a gas spring, an elastic sheet, etc.

[0051] As a simple replacement for the above scheme, the first slide groove 101 and the second slide groove 201 are retained, and the first sliding shaft 303 and the second sliding shaft 403 are replaced with the first slider and the second slider respectively. The first slider and the second slider slide in the first slide groove 101 and the second slide groove 201 respectively, and the first slider is rotationally connected to the first swing rod 3, and the second slider is rotationally connected to the second swing rod 4, which can also achieve limiting the opening and closing angles of the first swing rod 3 and the second swing rod 4.

[0052] Further, such as Figure 5 As shown, when the flip structure is in the closed state, the first frame 1 and the second frame 2 are placed horizontally, and the first slide groove 101 and the second slide groove 201 extend in the horizontal direction, which can reduce the longitudinal space occupied by the first frame 1 and the second frame 2.

[0053] It is understandable that as long as the first slide groove 101 and the second slide groove 201 have a tendency to extend horizontally, the effect of reducing the longitudinal volume of the first frame 1 and the second frame 2 can be achieved, but obviously, extending the slide groove in the horizontal direction can minimize the longitudinal volume of the frame.

[0054] In this embodiment, the first slide groove 101 and the second slide groove 201 are both waist-shaped holes, and the first swing rod 3 and the second swing rod 4 are both provided with a sliding shaft, which is confined in the waist-shaped hole, and the sliding shaft and the waist-shaped hole slide in cooperation with each other. The waist-shaped hole limits the travel range of the sliding shaft, but does not limit the rotation of the sliding shaft. The semicircular groove at the end of the waist-shaped hole is stably matched with the sliding shaft, and the sliding shaft is more stably positioned in the semicircular groove.

[0055] In one embodiment of the utility model, a flipping structure of an electric tool is proposed, wherein a first avoidance groove 301 is provided on the first swing arm 3, and the second swing arm 4 is connected to the first frame 1 by setting a second rotating member. When the flipping structure is opened, the first swing arm and the second swing arm swing crosswise, and the first avoidance groove 301 avoids the second rotating member. In this embodiment, the second rotating member is a second rotating shaft 402.

[0056] The second swing arm 4 has a second avoidance groove 401, and the first swing arm 3 is connected to the second frame 2 by setting a first rotating member. When the flip structure is opened, the first swing arm 3 and the second swing arm 4 swing crosswise, and the second avoidance groove 401 avoids the first rotating member. In this embodiment, the first rotating member is the first rotating shaft 302.

[0057] In other embodiments of the present application, the first swing arm 3 has the first avoidance groove 301 , and the second swing arm 4 does not have the second avoidance groove 401 ; or, the first swing arm 3 does not have the first avoidance groove 301 , and the second swing arm 4 has the second avoidance groove 401 .

[0058] like Figure 7 As shown, during the opening of the flip structure, the second swing arm 4 drives the second rotating shaft 402 to approach the first swing arm 3 along a predetermined path and finally moves into the first avoidance groove 301. The second swing arm 4 will eventually be hindered by the first swing arm 3 and cannot continue to move. The setting of the first avoidance groove 301 expands the rotation range of the second swing arm 4 relative to the first swing arm 3, and expands the opening and closing range of the flip structure. When applied to the battery compartment cover, the swing amplitude of the compartment cover is expanded; similarly, the second avoidance groove 401 on the second swing arm 4 is used to avoid the first rotating shaft 302 on the first swing arm 3, and expands the swing range of the first swing arm 3 relative to the second swing arm 4.

[0059] Furthermore, the first swing rod 3 is a curved rod that is bent and convex toward the hinged portion between the first swing rod 3 and the second swing rod 4, and the second swing rod 4 is a curved rod that is bent and convex toward the hinged portion between the first swing rod 3 and the second swing rod 4. Figure 4 As shown, the first swing rod 3 and the second swing rod 4 are bent at the hinge. When the cover is opened, the second frame 2 is flipped relative to the first frame 1 along the bending direction of the bending rod. Figure 7 The middle V direction is the bending direction mentioned above, and is also the rotation direction of the second frame 2. The positions of the first frame 1 and the second frame 2 are close to each other, and the bin cover and the bin body are flipped and close to each other, with good integration, avoiding a large gap between the bin cover and the bin body.

[0060] Reference Figure 4, with the hinge as the boundary, the first swing rod 3 includes a first long rod 304 and a first short rod 305 connected to each other, the length of the first long rod 304 is greater than the length of the first short rod 305, the first long rod 304 is connected to the first slide 101, and the first short rod 305 is connected to the second frame 2; the second swing rod 4 includes a second long rod 404 and a second short rod 405 connected to each other, the length of the second long rod 404 is greater than the length of the second short rod 405, the second long rod 404 is connected to the second slide 201, and the second short rod 405 is connected to the first frame 1. The length of the first long rod 304 is adapted to the length of the first slide 101, the length of the second long rod 404 is adapted to the length of the second slide 201, the first short rod 305 and the second short rod 405 are respectively connected to the second frame 2 and the first frame 1 at a relatively short distance, and the overall structure of the first swing rod 3 and the second swing rod 4 is compact, reducing the occupied space.

[0061] In this embodiment, the first swing arm 3 and the second swing arm 4 are both L-shaped bent arms, and the above-mentioned avoidance groove is formed inwardly at the bending portion of the L-shaped bent arm. The curved structure itself has a certain air avoidance effect, and the avoidance groove is designed at the same time, which can further expand the range in which the first swing arm 3 and the second swing arm 4 can swing relative to each other, thereby expanding the swing range of the flip structure.

[0062] As a simple replacement for the above solution, the first swing rod 3 and the second swing rod 4 are arc-shaped rods or arc-shaped plates, etc., which can also realize the flipping action of the flipping structure and have a certain air avoidance ability.
