Description

Technical Field

[0001] The present invention relates to the technical field of electric tools, and in particular to an electric tool. Background Art

[0002] Jig saws are widely used in the production and processing process. They are mainly used to cut metal and wood. Jig saws are often equipped with working accessories. The saw blade is the working saw blade of the jig saw. When working, the saw blade is installed on the output head and extends out of the base plate to be installed toward the workpiece. The base plate is abutted against the surface of the workpiece and the cutting is achieved through the reciprocating motion of the saw blade. The teeth of the jig saw are sharpened and have the characteristics of sharp cutting.

[0003] Therefore, the saw blade should usually be removed from the main machine when not in use to avoid safety hazards to the user due to the exposed saw blade.

[0004] However, during the short intervals between uses, frequent disassembly of the saw blade is time-consuming and laborious. At the same time, since the saw blade is exposed on the base plate, the jigsaw cannot be placed on the workbench through the base plate. Therefore, users usually place the jigsaw horizontally on the workbench during the intervals between uses. At this time, the saw blade still poses a risk of accidentally injuring the user. Summary of the Invention

[0005] In order to solve the deficiencies of the prior art, an object of the present invention is to provide a power tool that can stand with accessories.

[0063] The present invention will be described in detail below with reference to the accompanying drawings.

[0064] like Figure 1-2 The power tool of the present invention is shown in FIG. Specifically, the power tool of the embodiment of the present invention is a jigsaw 100. The jigsaw of the present invention is used for cutting metal, wood, and the like. Depending on the specific accessories installed, it can cut workpieces of different materials. The power tool of the embodiment of the present invention is specifically a jigsaw.

[0065] like Figure 2 As shown, the jig saw 100 includes a body 110 , a power assembly 140 , an output member 120 , a clamping device 130 , a battery pack 200 , and a base assembly 300 . The base assembly 300 includes a base 310 that contacts a workpiece.

[0066] See Attachment Figure 2 The fuselage 110 includes a first fuselage 111 and a second fuselage 112 connected to each other. The first fuselage 111 and the second fuselage 112 are arranged at an angle to each other. The first fuselage 111 has a first fuselage axis 102, and the second fuselage 112 has a second fuselage axis 103. The first fuselage axis 102 is perpendicular to the bottom plate 310, and the second fuselage axis 103 is parallel to the bottom plate 310.

[0067] In this embodiment, the first body 111 extends in an up-down direction substantially perpendicular to the bottom plate assembly 300, and the second body 112 extends in a front-to-back direction substantially parallel to the bottom plate assembly 300. The up-down direction in the present invention refers to a direction parallel to the first axis 102, the side away from the bottom plate assembly 300 is the top, and the side close to the bottom plate assembly 300 is the bottom. The front-to-back direction refers to a direction parallel to the second body axis 103, the side close to the working accessories is the front, and the side close to the battery pack is the rear.

[0068] like Figure 5 As shown, the base plate assembly 300 is arranged outside the body 110 and connected to the first body 111. The base plate assembly 300 includes a base plate 310 and a rotating connection portion 320, wherein the base plate 310 contacts the workpiece, and the rotating connection portion 320 is rotatably connected to the first body 111, wherein the rotating connection portion 320 and the first body 111 are configured to be rotatably connected with the first axis 101 as the axis, wherein the first axis 101 is parallel to the plane where the base plate 310 is located, thereby enabling the jig saw 100 to achieve bevel cutting.

[0069] See attached Figure 5 The bottom plate 130 is formed with a bottom plate plane for contacting the workpiece, and the rotating connection part 320 is used to connect the bottom plate 130 with the fuselage 110. The rotating connection part 320 has a protrusion from the bottom plate 130 toward the fuselage 110. The rotating connection part 320 is roughly arched and extends basically in a direction parallel to the first axis 101; the rotating connection part 320 is connected to the fuselage 110 through a connecting component.

[0070] See also Figure 3-Figure 4 The power assembly 140 includes a motor 141 and a transmission assembly. The motor 141 is connected to the output member 120 via the transmission assembly, wherein the transmission assembly in this embodiment includes an eccentric gear assembly 142; the output member 120 of the present invention is a reciprocating rod, which extends along an axial direction parallel to the first fuselage 111, and the reciprocating rod is driven to reciprocate by the motor 141.

[0071] Specifically, if Figure 4 As shown, the motor 141 is disposed in the second body 112 , and the motor gear at the motor output end is engaged with the eccentric gear. The rotation of the motor 141 drives the eccentric gear to rotate, thereby driving the reversing rod to move up and down.

[0072] The clamping device 130 is connected to the reciprocating rod and is used to clamp the working accessory 400. In this embodiment of the present invention, the working accessory 400 is a saw blade; the saw blade is mounted outside the body 110 and has teeth formed on one side. The saw blade cuts the workpiece through its reciprocating motion. The clamping device 130 is located at the end of the reciprocating rod, and a portion of the working accessory 400 is inserted into and secured to the clamping device 130. Specifically, the clamping device 130 has a chamber formed therein. When the working accessory 400 is mounted to the clamping device 130, a portion of the working accessory 400 is accommodated and secured within the chamber.

[0073] like Figure 4 As shown, the motor 141 is supported in the second body 112 via the motor front bearing 143 and the motor rear bearing 144. The inner wall of the shell of the second body 112 is provided with a rear bearing seat. The motor rear bearing 144 is supported in the rear bearing seat 145. A bearing frame 150 is also provided. Figure 5 The bearing frame 150 is an L-shaped bracket, which includes a supporting portion 151 and a reinforcing portion 152, wherein the supporting portion 151 is arranged in the first fuselage 111 and extends along the axis of the first fuselage 111, and the reinforcing portion 152 is partially located outside the fuselage and connected to the base plate assembly 300.

[0074] For details, see the attached Figure 4The support part 151 is provided with a motor bearing unit and an eccentric gear support unit. The motor bearing unit is provided with a motor front bearing 143, and the eccentric gear support unit is provided with an eccentric gear bearing. The support part 151 mainly plays a supporting role; the reinforcement part extends in a direction parallel to the bottom plate 310, and the reinforcement part includes a balancing reinforcement part 152 extending in a direction away from the first fuselage 111.

[0075] By providing a balancing reinforcement portion 152 extending parallel to the bottom plate 310, the connection strength between the bearing frame 150 and the base assembly 300 can be improved, and the overall strength of the fuselage can also be improved; on the other hand, by extending the balancing reinforcement portion 152 in a direction away from the first fuselage 111, the balance of the entire machine can be improved, avoiding the imbalance of the fuselage caused by the heavier weight of the first fuselage 111, thereby avoiding the need for the user to apply a large force to the second fuselage 112 to balance the entire machine during use, thereby improving the user's operating experience.

[0076] like Figure 5 As shown, the balancing reinforcement portion 152 is arranged to extend out of the first fuselage 111, and after the balancing reinforcement portion 152 extends out of the fuselage, it is connected to the rotating connection portion 320 of the bottom plate assembly 300. Since the rotating connection portion 320 has a protruding outer circumferential surface, the bottom of the balancing reinforcement portion 152 is provided with a recessed inner circumferential surface that cooperates with the outer circumferential surface. The outer circumferential surface and the inner circumferential surface are coaxially arranged, and the rotating connection portion 320 is connected to the balancing reinforcement portion 152 through a connecting assembly.

[0077] Specifically, see Appendix Figure 5 The rotating connection part 320 includes an internal area close to the base plate 310 and an external area away from the base plate 310, wherein a connecting hole 321 is provided at the top center of the rotating connection part 320, and the connecting assembly includes a square nut 331, a clamping plate 332 and a screw 333, wherein the clamping plate 332 and the connecting hole 321 are arranged in the internal area correspondingly, and the square nut 331 and the connecting hole 321 are arranged in the external area correspondingly, and the screw 333 passes through the clamping plate 332 and the connecting hole 321 in sequence and is fixedly connected to the square nut 331.

[0078] Furthermore, the connecting hole 321 is an arc-shaped connecting hole extending in the circumferential direction and provided on the outer peripheral surface of the rotating connecting portion 320. The fixed position of the bearing frame 150 and the rotating connecting portion 320 can be adjusted through the connecting assembly, thereby allowing the rotating connecting portion 320 of the base plate assembly 300 and the first body 111 to be configured as a rotating connection with the first axis 101 as the axis, thereby realizing the bevel cutting of the jig saw 100.

[0079] Of course, the reinforcement portion further includes an auxiliary reinforcement portion 153 , wherein the auxiliary reinforcement portion 153 includes spokes provided on both sides of the balance reinforcement portion. The auxiliary reinforcement portion 153 is used to improve the supporting strength of the bearing frame 150 and the entire machine.

[0080] The bearing frame in this embodiment of the present invention also includes a reinforcement assembly, which cooperates with the fuselage inner shell to strengthen and secure it. The reinforcement assembly includes connecting ribs 155 and connecting posts 154. The connecting ribs 155 are provided on the surface where the support portion 151 mates with the fuselage inner shell, and the connecting posts 154 are provided on the reinforcement portion, specifically, on the outer side of the spokes of the auxiliary reinforcement portion 153. The connecting ribs 155 can cooperate with grooves in the inner wall of the first fuselage to strengthen the connection stability between the bearing frame's support portion and the fuselage. Similarly, the connecting posts 154 can cooperate with holes in the inner wall of the first fuselage to strengthen the connection stability between the bearing frame's reinforcement portion and the fuselage.

[0081] Of course, to further enhance the connection strength between the bearing frame and the fuselage, the reinforcement assembly also includes a connecting boss 156 provided on the support portion. Connecting boss 156 has screw holes defined therein. Correspondingly, screw holes are also defined on the inner wall of the fuselage, allowing screws to secure connecting boss 156 to the fuselage. This further enhances the connection strength between the bearing frame and the fuselage, making the connection more reliable and stable.

[0082] The bearing frame 150 in this embodiment is an integrated structure, which can be an aluminum bearing frame, and of course can also be set as other metal bearing frames, which is not limited here.

[0083] The battery pack 200 is connected to the rear end of the second body 112 and supplies power to the power component. Specifically, the battery pack 200 is connected to the extension foot of the second body 112. A control component is also provided at the extension foot of the second body 112, and the control component mainly includes a control circuit board.

[0084] See Attachment Figure 6 The battery pack 200 includes a first support unit 210, and the base plate assembly 300 includes a second support unit 340, wherein the first support unit 210 and the second support unit 340 are located in the same support plane 700; the first support unit 210 and the second support unit 340 jointly support the jigsaw 100 to make it stand, so that when the tool stands, the working accessory 400 faces the support plane 700.

[0085] By arranging the first supporting unit and the second supporting unit on the tool, the tool can stand on the work surface during use, avoiding the leakage of work accessories when the tool is placed horizontally on the table due to the inability to stand, or safety hazards caused by the tool sliding or falling.

[0086] The first support unit 210 is configured as a linear support unit or a surface support unit, and the second support unit 340 can also be configured as a linear support unit or a surface support unit. In this embodiment, a portion of the outer shell of the battery pack 200 constitutes the first support unit 210, wherein the portion of the outer shell of the battery pack 200 in contact with the work surface can be in surface contact or linear contact. For example, the entire bottom surface of the battery pack 200 can serve as the first support unit 210, where the bottom surface refers to the side of the battery pack facing away from the plug-in end. In this embodiment, the rear side of the bottom plate 310 facing away from the output element constitutes the second support unit 340, where the rear side refers to the side located behind the bottom plate 310.

[0087] By supporting the tool with the rear side plate of the base plate 310 and part of the outer shell of the battery pack 200, on the one hand, the tool can stand up during use, avoiding the safety hazard of lying the tool directly on the operating table; on the other hand, while ensuring that the tool stands up, the working accessories are facing the supporting plane 700, which also avoids repeated disassembly and assembly of the working accessories to ensure safety during use.

[0088] In this embodiment, the first support unit 210 and the second support unit 340 are spaced apart, and when the tool is standing, the projection of the tool's center of gravity onto the support plane 700 is located between the first support unit 210 and the second support unit 340. This arrangement makes the tool more stable, preventing it from tipping over due to unstable standing. When the tool is standing, the angle α between the surface of the base plate 310 and the support plane 700 is 35°≤α≤60°, and more preferably 45°≤α≤50°.

[0089] The above angle setting, on the basis of ensuring that the tool stands, further ensures that the working accessories on the tool will be as close to the operating table as possible when standing, thereby further improving the safety of the tool when standing and avoiding accidental injury to the operator by the working accessories when the tool stands.

[0090] The jigsaw 100 in this embodiment includes two grips: a first grip located on the first body 111 and a second grip located on the second body 112. When operating the jigsaw 100, a user can grip the saw using either the first grip or the second grip, or with both hands. In this embodiment, the front end of the first body 111 constitutes the first grip. The user can hold the front end of the first body 111 with their palm and wrap their thumb around the top and rear side of the first body 111. The outer peripheral wall of the second body 112 constitutes the second grip.

[0091] Among them Figure 2As shown, the first gripping portion further includes a first elastic portion 1111 , and similarly, the second gripping portion also includes a second elastic portion 1121 , wherein the second elastic portion 1121 almost completely covers the outer peripheral wall of the second body 112 .

[0092] The first elastic portion 1111 covers at least the front wall of the first body 111 , wherein the first elastic portion 1111 covers an area ratio greater than or equal to 50% of the outer shell of the first body 111 , and more than 50% of the outer shell of the first body 111 is covered by the first elastic portion.

[0093] In this embodiment, the first elastic portion 1111 covers the front wall of the first body 111 and extends from the front wall to the side walls and top wall, covering part of the side walls and top wall. The provision of the first elastic portion 1111 can improve the user's feel and reduce operator fatigue caused by vibration during the cutting process.

[0094] See attached Figure 7 The first body 111 of the present invention includes an upper finger stop 160 and a lower finger stop 170 located on its rear sidewall. The upper finger stop 160 is positioned above the second body 112, while the lower finger stop 170 is positioned below the second body 112. The difference ΔL between the upper finger stop 160 and the lower finger stop 170 satisfies the following conditions: -15mm≤ΔL≤30mm, where ΔL is less than 0 and the lower finger stop 170 is positioned behind the upper finger stop 160, and ΔL is greater than 0 and the upper finger stop 160 is positioned in front of the lower finger stop 170. Furthermore, if the outer diameter of the second body 112 is D, then 35mm≤D≤65mm. This embodiment includes two gripping positions. In the first gripping position, the upper finger stop 160 is located in front of the lower finger stop 170. At this time, the front-to-back distance difference ΔL between the upper finger stop 160 and the lower finger stop 170 is 3mm<ΔL≤15mm.

[0095] In order to make the structure of the whole machine compact, the prior art usually does not allow three fingers to wrap around the grip of the machine body. Usually, the user's thumb and index finger are wrapped around the grip part, and the other fingers are attached to the side wall of the machine body. Therefore, when grasping the machine, the user can only rely on the clamping force between the thumb and index finger. This kind of grip is laborious and unreliable, and the user can easily feel uncomfortable when operating for a long time.

[0096] The embodiment of the present invention enables the user to hold the machine with at least three fingers by setting the front-to-back distance between the upper finger stop 160 and the lower finger stop 170 within the above-mentioned range, that is, at least three fingers are allowed to surround the bottom of the second body. At this time, the fingers below the second body 112 are close to the lower finger stop 170, and the base of the user's hand is close to the upper finger stop 160. This holding method is reliable and comfortable, and it is convenient for the user to easily pick up and put down the machine.

[0097] Of course, as an alternative embodiment, the front-to-back distance difference ΔL between the lower finger stop 170 and the upper finger stop 160 may also be set to -10 mm ≤ ΔL ≤ 3 mm.

[0098] By setting the front-to-back distance between the upper finger stop 160 and the lower finger stop 170 within the above range, the user can hold the second body with at least four fingers, that is, at least four fingers are allowed to surround and hold the second body below. This holding method is also beneficial to improving the user's holding comfort and holding reliability.

[0099] In the embodiment of the present invention, by setting the above-mentioned second body 112 within the above-mentioned size range, it is convenient for users to hold it with one hand, and the proportion of the user's hand holding area to the outer peripheral surface of the second body is increased, thereby improving the reliability of holding; at the same time, the relative position setting of the front and rear finger guards makes the user's grip more comfortable, which is conducive to improving the user's usage experience; and allows the user to hold it with three or even four fingers, thereby improving the user's grip comfort and improving the user's controllability of the machine.

[0100] like Figure 5 As shown, in this embodiment, the bottom plate 310 includes a pair of first sides 311 extending in the front-to-back direction and a pair of second sides 312 extending in the left-to-right direction, wherein the first side is perpendicular to the second side 312, and the first side 311 intersecting the second side 312 is shorter, wherein see the attached Figure 8 The projection of the second fuselage 112 onto the bottom plate 130 includes a left limit outer edge 1123 and a right limit outer edge 1122, wherein the left limit outer edge 1123 and the right limit outer edge 1122 are both located between a pair of first edges 311; wherein the left limit outer edge 1123 is spaced apart from the first edge 311 adjacent thereto, and the right limit outer edge 1122 is spaced apart from another first edge 311' adjacent thereto.

[0101] The left-right distance H1 between the left limit outer edge 1123 and the first side 311 adjacent thereto is greater than or equal to 5 mm and less than or equal to 15 mm; similarly, the left-right distance H2 between the right limit outer edge and the other first side adjacent thereto is greater than or equal to 5 mm and less than or equal to 15 mm.

[0102] Among them, the left limit outer edge in this embodiment refers to the leftmost edge of the second body 112 shell, that is, the contour line or point closest to the first side 311 on the left; the right limit outer edge refers to the rightmost edge of the second body 112 shell, that is, the contour line or point closest to the first side 311 on the right.

[0103] See attached Figure 8In the figure, the upper edge is the right limit outer edge 1122, and the lower edge is the left limit outer edge 1123. By setting the left and right limit outer edges of the second fuselage within a pair of first edges of the bottom plate, there is a gap between the second fuselage 112 and the first edge of the bottom plate during vertical use, which is conducive to the operation of the tool in a small space. For example, when the first edge 311 of the bottom plate is close to the wall or the outer wall of an object, there is a gap between the outer wall of the second fuselage 112 and the wall or the outer wall of the object, so there is space for the user to hold it.

[0104] See attached Figures 8-10 The jigsaw 100 in this embodiment of the present invention further includes a lighting unit 800 disposed at the output end; the lighting unit 800 is connected to the control mechanism via a wire. The lighting unit 800 surrounds or partially surrounds the output element 120. In this embodiment, the lighting unit 800 is a ring-shaped lighting unit, eccentrically disposed relative to the output element. Alternatively, the lighting unit 800 may be an open ring or a horseshoe-shaped lighting unit, without limitation.

[0105] See Attachment Figure 10 , a distance a between the central axis of the annular lighting unit 800 and the central axis of the output element 120 is greater than 0 and less than or equal to 5 mm.

[0106] Specifically, see Appendix Figure 8 and Figure 10 The clamping device 130 in the embodiment of the present invention is roughly cylindrical, wherein the outer diameter of the lighting unit 800 is larger than the outer diameter of the clamping device 130, and the ratio of the outer diameter d1 of the lighting unit 800 to the outer diameter d2 of the clamping device 130 is greater than 1 and less than 3, that is, 1<d1 / d2<3.

[0107] The eccentric arrangement of the lighting unit 800 and the clamping device 130 facilitates clearer illumination of the cutting position of the work accessory by the lighting unit 800, thereby avoiding the cutting position of the work accessory being located in the blind spot of the lighting unit 800 and providing clearer illumination. Simultaneously, limiting the outer diameter of the lighting unit 800 and the outer diameter of the clamping device 130 within the above ranges avoids a situation where the illumination range is too small due to the lighting unit 800 being too small, and also avoids insufficient light intensity due to the lighting unit 800 being too large. Thus, the above arrangement ensures that the lighting unit 800 can illuminate a certain range around the work accessory and clearly illuminate the work accessory.

[0108] The jigsaw 100 of the present invention further includes a switch assembly, wherein the switch assembly 500 in this embodiment includes a push button 510, a pull rod 520, and a switch 530, wherein the switch 530 is disposed in the second body 112, the push button 510 is connected to the pull rod 520, the push button 510 is disposed outside the second body 112, and the pull rod 520 is disposed inside the second body 112 and extends along the axis of the second body 112. By toggling the push button 510, the pull rod 520 can be driven to move along the axis of the second body 112.

[0109] like Figure 11-Figure 11 As shown, the push button 510 is provided on the pull rod 520 , and the pull rod 520 includes a trigger portion 523 , a thin neck portion 521 and a connecting portion 522 , wherein the trigger portion 523 is used to trigger the switch 530 , and the connecting portion 522 connects the thin neck portion 521 and the push button 510 .

[0110] Specifically, if Figure 11 As shown, the rear bearing seat 145 in the second body 112 is provided with an opening 1451 extending therethrough, and the narrow neck portion 521 passes through and slides within the opening 1451. A connecting hole 5231 is provided on the trigger portion 523, which is connected to the trigger unit of the switch 530. The trigger unit of the switch 530 is specifically a dial button 531. The connecting hole 5231 is sleeved on the dial button 531. Pushing the key 510 drives the pull rod 520 to reciprocate, thereby driving the dial button 531 to open or close. The switch 530 is electrically connected to the control component via a wire, and the switch 530 can control the start and stop of the motor 141 through the control component.

[0111] The connecting portion 522 is further provided with a guide member for guiding the push rod 520 to slide in connection with the inner wall of the second body 112. Specifically, the guide member includes a slide groove provided on the connecting portion 522 and a guide rib provided on the inner wall of the second body 112. Of course, the connecting portion 522 may be provided with a guide rib and the inner wall of the second body 112 may be provided with a guide groove, and this is not limited to this.

[0112] Usually, according to the holding habit, the user's fingers are usually close to the front end of the fuselage when holding it. Therefore, setting the push key at the front end is more convenient for user operation. In this embodiment, a switch pull rod including a thin neck is provided, so that the thin neck is set through the rear bearing seat 145 of the motor. On this basis, the push key 510 is set forward on the second fuselage, and at the same time, the electrical connection between the pull rod 520 and the switch 530 located on the rear side of the second fuselage is satisfied. In addition, there is no need to reserve additional space in the second fuselage for arranging the pull rod, which reduces the size of the second fuselage, especially the external radial size of the second fuselage.

[0113] See attached Figure 13The jigsaw 100 of the present invention further includes a speed control assembly 600, which includes a speed control knob 610, a speed control circuit board, and a speed control wire. The speed control assembly 600 is electrically connected to the battery pack 200 via a wire, and the speed control circuit board is connected to the circuit board of the control mechanism via a wire, thereby controlling the speed of the motor 141. The speed control knob 610 is disposed on the top of the first housing 111 and has a rotation axis 611 around which it can rotate. The rotation axis 611 is disposed perpendicular to the bottom plate 310, or the rotation axis 611 is disposed parallel to the bottom plate 310. The speed control knob 610 is disposed on the top of the first housing 111, allowing the user to conveniently adjust the speed while holding the knob.

[0114] Among them Figure 13 As shown, in the embodiment of the present invention, the rotation axis 611 of the speed control knob 610 is perpendicular to the bottom plate, and the distance L between the rotation axis 611 and the first fuselage axis 102 is greater than or equal to 10 mm and less than or equal to 25 mm.

[0115] Specifically, see Appendix Figure 14 The speed control knob 610 is disposed in the mounting area 900 on the rear side of the first body 111. Specifically, the knob center 612 of the speed control knob 610 is located in the mounting area 900. The mounting area 900 includes a first mounting area 910 and a second mounting area 920. The first mounting area 910 refers to the area covered by the second body axis 103 when rotated approximately 90° clockwise around the first body axis 102, and the second mounting area 920 refers to the area covered by the second body axis 103 when rotated approximately 90° counterclockwise around the first body axis 102. By arranging the speed control knob 610 in this manner, the user's speed control operation is more facilitated, thereby improving the user experience.
