Description

Technical Field

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

[0002] Power tools are indispensable tools in people's daily lives, and there are many types of power tools, especially small handheld power tools are very popular, including angle grinders, electric drills, polishers and electric circular saws, etc. The common way to start power tools is to apply pressure to the switch button to make it contact with the trigger inside the power tool to start the power tool. However, when the switch button is released, it will be disconnected from the trigger, so that the power tool stops running.

[0003] Although the above-mentioned start or stop method is easy to operate, there is at least one of the following technical problems in the relevant technology: when the power tool is moved in a non-processing state, the switch button may be accidentally triggered, causing the power tool to enter the start-up state, which may easily cause a safety accident. Summary of the invention

[0004] The present invention solves the technical problem that in the process of moving the electric tool in a non-processing state, a switch button is easily triggered by mistake, causing the electric tool to enter an on-operation state, thereby easily causing a safety accident.

[0005] In order to solve the above-mentioned problem, the present invention provides a housing assembly of an electric tool, wherein the trigger of the electric tool is arranged in the housing assembly; the housing assembly comprises: a mounting housing, in which a first mounting position for mounting the trigger is arranged; a switch assembly, movably connected to a mounting groove of the mounting housing, and the switch assembly is used to be electrically connected to the trigger; a locking member, arranged in a matching groove of the mounting housing, and the locking member moves in the matching groove to enable the switch assembly to switch between a first state and a second state; wherein, when the trigger is arranged in the mounting housing, if the switch assembly is in the first state, the switch assembly is continuously electrically connected to the trigger; in the second state, the switch assembly maintains a first distance from the trigger.

[0006] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: in combination with the actual processing situation, when the electric tool is idle, the position of the locking piece in the matching groove is adjusted so that the switch assembly cannot be contacted with the trigger when it is pressed, that is, the situation of false triggering and starting is avoided. Conversely, when processing is required, the position of the locking piece in the matching groove is moved again so that the switch assembly can be pressed to be electrically connected with the trigger. Therefore, due to the existence of the locking piece, the state of the electric tool can be clearly distinguished into a working state and a waiting state, meeting the requirements for safe use. In addition, when the electric tool is used as a tool for family use, it can effectively avoid safety accidents caused by being accidentally triggered by children, that is, it plays the role of a child lock; by adjusting the position of the locking piece in the matching groove, the electric tool can be kept in the power-on running state, avoiding the startup of the electric tool from being too dependent on the continuous pressing action of the operator, so that in the actual processing process, even if the operator's hand is detached from the switch assembly, the electric tool will not stop running, thereby ensuring the stable progress of the processing.

[0007] In one example of the present invention, the locking member includes: a locking plate, connected to the matching groove to transversely penetrate the mounting shell, and a limiting groove is provided on a side of the locking plate close to the switch assembly; a limiting member is provided at a position of the locking plate corresponding to the limiting groove; wherein, when the switch assembly is in the first state, the limiting member limits the switch assembly from escaping from the limiting groove; and when the switch assembly is in the second state, the limiting member limits the switch assembly from entering the limiting groove.

[0008] Compared with the prior art, the technical effect achieved by adopting this technical solution is: combined with the simple structural setting of the locking piece, its moving direction in the mating groove is combined with the movement state of the switch assembly to achieve a linkage effect of switching the electric tool between the on and off states.

[0009] In one example of the present invention, the movement direction of the switch assembly intersects or is perpendicular to the movement direction of the locking member; the limiting member includes: a first limiting section, which is arranged inside the first inner side surface of the limiting groove; and the first limiting section extends toward the second inner side surface of the limiting groove; wherein, the first inner side surface and the second inner side surface are arranged opposite to each other along the transverse direction, and a first matching spacing for allowing the switch assembly to enter the limiting groove is formed between the first limiting section and the second inner side surface; wherein, when the locking member is adjusted to move along the transverse direction so that the locking portion of the switch assembly is buckled to the first limiting section, the switch assembly maintains the first state; when the locking portion is mounted on a side of the first limiting section away from the limiting groove, the switch assembly enters the second state, or, when the locking portion is arranged at the first matching spacing, the switch assembly can switch between the first state and the second state.

[0010] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the switch component can be stably switched between the first state and the second state.

[0011] In an example of the present invention, the limiting member further includes: a second limiting section, which is disposed on the second inner side surface and is arranged opposite to the first limiting section, and a second matching spacing is formed therebetween for the locking portion to enter the limiting groove.

[0012] Compared with the prior art, the technical effect achieved by adopting this technical solution is that by adding a second limit section, it is possible to adjust the locking member to achieve linkage with the switch assembly and the trigger more conveniently and efficiently.

[0013] In one example of the present invention, the first limit section and the second limit section at most partially overlap in the projection along the lateral direction, and the distance between the first limit section and the bottom of the limit groove is greater than the distance between the second limit section and the bottom of the groove; wherein, when the locking portion abuts against an end of the second limit section away from the limit groove, the first spacing is maintained between the switch assembly and the trigger; and when the locking portion is buckled onto the first limit section, the locking portion and the projection of the second limit section along the lateral direction at least partially overlap.

[0014] In one example of the present invention, at least one blocking member is provided in the mounting shell; the locking plate is provided with a mating member for mating with the at least one blocking member; wherein the blocking member cooperates with the mating member to limit the locking plate from escaping from the mating groove.

[0015] In one example of the present invention, there are two mating pieces, and the two mating pieces are symmetrically arranged about the locking plate along the transverse direction; the locking piece also includes: a reset piece, which is clamped in the clamping space formed by the two mating pieces, and the reset piece has a deformation force along the transverse direction; wherein, when the blocking piece cooperates with the corresponding mating piece, the reset piece cooperates with the corresponding inner wall of the mounting shell, and the deformation amount of the reset piece is the first deformation amount; when the blocking piece is separated from the mating piece, the reset piece is separated from the corresponding inner wall of the mounting shell, and the deformation amount of the reset piece is less than the first deformation amount.

[0016] In one example of the present invention, a second mounting position and a third mounting position for clamping the switch assembly therein are provided in the mounting shell; the switch assembly includes: a switch body, which is rotatably connected to the mounting shell; and the axis direction around which the switch body rotates is coplanar with the moving direction of the locking member in the matching groove; a first elastic member, which is provided between the second mounting position and the switch body, and the first elastic member applies a first elastic force to the switch body to make it move away from the first mounting position; a second elastic member, which is provided between the third mounting position and the switch body, and the second elastic member applies a second elastic force to the switch body to make it move close to the first mounting position; wherein the first elastic force is greater than the second elastic force.

[0017] In an example of the present invention, the installation shell is in the shape of an elongated strip, and the installation shell is composed of a right shell and a left shell extending along the length direction thereof.

[0018] On the other hand, the present invention also provides an electric tool, comprising: a shell assembly as provided in any of the above examples; a drive assembly, which is arranged in the installation space of the installation shell, and the drive assembly is located at the output end of the installation shell; a battery pack, which is obliquely installed at one end of the installation shell away from the output end; wherein a plane for sliding connection of the battery pack is formed on the installation shell, and the plane is arranged at a different plane from the axis where the drive shaft of the drive assembly is located.

[0019] Compared with the prior art, the technical effect achieved by adopting this technical solution is: it can achieve the technical effect corresponding to any of the above-mentioned technical solutions, which will not be repeated here.

[0020] After adopting the technical solution of the present invention, the following technical effects can be achieved:

[0021] (1) By adjusting the position of the locking piece in the matching groove, the power tool can be kept in the on-state, which avoids the power tool starting being too dependent on the operator's continuous pressing action. In the actual processing process, even if the operator's hand is separated from the switch assembly, the power tool will not stop running, thereby ensuring stable processing;

[0022] (2) By adding a second limit segment, it is possible to make it more convenient and efficient to adjust the locking member to achieve linkage with the switch assembly and the trigger. Specifically, in order to make the overall adjustment process efficient and convenient, a limit card can be provided on the mounting housing. The limit card is used to install an elastic member connected to the switch assembly. The elastic member applies an elastic force to the switch assembly to rotate it in a clockwise direction, that is, an elastic force to cause the switch assembly to move away from the locking member. Under the action of the elastic member, the power tool needs to overcome the elastic force to start running, further reducing the accidental occurrence of false triggering. When the locking part enters the limit groove and cooperates with the first limit segment, combined with the elastic force of the elastic member, the locking part and the first limit segment can be squeezed against each other, further reducing the risk of the locking part and the first limit segment being separated under the vibration state generated during the processing.

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Embodiment 1:

[0037] See also Figure 1 , which is a schematic structural diagram of a housing assembly of an electric tool 100 provided in Embodiment 1 of the present invention. Figure 2-Figure 10 The trigger 110 of the electric tool 100 is disposed in a housing assembly. Specifically, the housing assembly includes, for example, a mounting housing 10, a switch assembly 20, and a locking member 30. A first mounting position 111 for mounting the trigger 110 is disposed in the mounting housing 10; the switch assembly 20 is movably connected to the mounting slot of the mounting housing 10, and the switch assembly 20 is used to be electrically connected to the trigger 110; the locking member 30 is disposed in the matching slot 11 of the mounting housing 10, and the locking member 30 moves in the matching slot 11 so that the switch assembly 20 can be switched between a first state and a second state; wherein, when the trigger 110 is disposed in the mounting housing 10, if the switch assembly 20 is in the first state, the switch assembly 20 is continuously electrically connected to the trigger 110; in the second state, the switch assembly 20 maintains a first distance from the trigger 110.

[0038] In a specific example, in combination with the actual processing situation, when the power tool 100 is idle, the position of the locking member 30 in the matching groove 11 is adjusted so that when the switch assembly 20 is pressed, it cannot contact the trigger 110, that is, the situation of false triggering and starting is avoided. Conversely, when processing is required, the position of the locking member 30 in the matching groove 11 is adjusted again so that the switch assembly 20 can be pressed to be electrically connected to the trigger 110. Therefore, due to the presence of the locking member 30, the state of the power tool 100 can be clearly distinguished into a working state and a waiting state, meeting the requirements for safe use. In addition, when the power tool 100 is used as a household tool, it can effectively avoid safety accidents caused by being accidentally triggered by children, that is, it has the effect of a child lock.

[0039] Furthermore, in combination with the contents of the present technical solution, by adjusting the position of the locking piece 30 in the mating groove 11, the power tool 100 can be kept in the on-state, thereby preventing the startup of the power tool 100 from being overly dependent on the operator's continuous pressing action. In the actual processing process, even if the operator's hand is detached from the switch assembly 20, the power tool 100 will not stop running, thereby ensuring stable processing.

[0040] Furthermore, the locking member 30 includes, for example, a locking plate 31 and a limiting member. The locking plate 31 is connected to the matching groove 11 to horizontally penetrate the mounting housing 10, and a limiting groove 35 is provided on one side of the locking plate 31 close to the switch assembly 20; the limiting member is provided at a position of the locking plate 31 corresponding to the limiting groove 35; wherein, when the switch assembly 20 is in the first state, the limiting member limits the switch assembly 20 from escaping from the limiting groove 35; and when the switch assembly 20 is in the second state, the limiting member limits the switch assembly 20 from entering the limiting groove 35.

[0041] Specifically, in combination with the actual use process, when the operator applies pressing force to the switch assembly 20 to start the power tool 100, the position of the moving locking plate 31 in the matching groove 11 is made so that the switch assembly 20 entering the limit groove 35 cannot be disengaged from the limit groove 35 under the restriction of the limit member, thereby allowing the power tool 100 to continue to maintain the operating state; of course, conversely, when the locking plate 31 is moved in a direction opposite to the above-mentioned moving direction, the switch assembly 20 is first disengaged from the limit member and then disengaged from the limit groove 35, and then the locking plate 31 is moved in the same direction again, so that when a pressing action is applied to the switch assembly 20 again, the switch assembly 20 cannot enter the limit groove 35 under the limiting action of the limit member, so that a distance is maintained between the switch assembly 20 and the trigger 110, that is, the power tool 100 is in the off state. Therefore, combined with the simple structural setting of the locking member 30, its movement direction in the matching groove 11 is combined with the movement state of the switch assembly 20 to achieve a linkage effect of switching the power tool 100 between the on and off states.

[0042] Preferably, the movement direction of the switch assembly 20 intersects or is perpendicular to the movement direction of the locking member 30; the limiting member, for example, includes a first limiting section 32, specifically, the first limiting section 32 is arranged inside the first inner side surface of the limiting groove 35; and the first limiting section 32 extends toward the second inner side surface of the limiting groove 35; wherein the first inner side surface and the second inner side surface are arranged opposite to each other in the transverse direction, and a first matching spacing for the switch assembly 20 to enter the limiting groove 35 is formed between the first limiting section 32 and the second inner side surface; wherein, when the locking member 30 is adjusted to move in the transverse direction so that the locking portion 21 of the switch assembly 20 is buckled to the first limiting section 32, the switch assembly 20 maintains the first state; when the locking portion 21 is arranged on the side of the first limiting section 32 away from the limiting groove 35, the switch assembly 20 enters the second state, or, when the locking portion 21 is located at the first matching spacing, the switch assembly 20 can switch between the first state and the second state.

[0043] Combination Figure 4 In a specific example, the movement direction of the switch assembly 20 and the movement direction of the locking member 30 are perpendicular to each other, and the switch assembly 20 can be rotated in the mounting housing 10, while the locking member 30 is linearly movable in the matching groove 11. Specifically, the switch assembly 20 is arranged at a lower position in the mounting housing 10; the matching groove 11 is arranged in the mounting housing 10 and penetrates along the front-to-back direction of the mounting housing 10, that is, transversely, and the matching groove 11 is located at an upper position of the switch assembly 20, and correspondingly, the locking member 30 is also located at an upper position of the switch assembly 20; and the locking member 30 is fixedly connected to the inside of the mounting housing 10 and is arranged above the switch assembly 20.

[0044] Continue to combine Figure 4More specifically, the position where the switch assembly 20 is rotatably connected to the mounting housing 10 is located at the right side of the locking member 30, and the trigger 110 is located at the left side of the locking member 30. Therefore, when the switch assembly 20 rotates counterclockwise 101, it moves in a direction away from the locking member 30 and the trigger 110 at the same time; conversely, when the switch assembly 20 rotates clockwise, the switch assembly 20 moves in a direction close to the locking member 30 and the trigger 110 at the same time. Combined with the movement of the locking member 30 in the matching groove 11, the locking portion 21 can be arranged relative to or offset with the first matching spacing. When the two are arranged relative to each other, the switch assembly 20 can be pressed to pass through the first matching spacing and enter the limiting groove 35. Conversely, when the two are offset, the first limiting section 32 blocks the locking portion 21 from entering the limiting groove 35.

[0045] Furthermore, when the lock part 21 enters the limiting groove 35, it can push the moving part arranged in the matching groove 11, so that the lock part 21 is mounted on the first limiting section 32, so that the switch assembly 20 and the trigger 110 are kept in contact, that is, the electric tool 100 is kept in operation. Of course, when it is necessary to control the electric tool 100 to switch to the shutdown state, it is only necessary to move the lock part 30 in the direction opposite to the above-mentioned moving direction, so that the first limiting section 32 and the lock part 21 are separated from each other, and then the lock part 21 is disengaged from the limiting groove 35 along the first matching spacing, and then the lock part 30 is kept moving in the direction of separation to displace the lock part 21 with the first matching spacing, so that the first limiting section 32 plays a role in limiting the switch assembly 20 from entering the limiting groove 35.

[0046] Furthermore, the limiting member, for example, further includes a second limiting section 33 , which is disposed on the second inner side surface and is arranged opposite to the first limiting section 32 , forming a second matching spacing 34 therebetween for the locking portion 21 to enter the limiting groove 35 .

[0047] Preferably, the first limiting section 32 and the second limiting section 33 overlap at most in the lateral projection, and the distance between the first limiting section 32 and the bottom of the limiting groove 35 is greater than the distance between the second limiting section 33 and the bottom of the groove; wherein, when the locking portion 21 abuts against the end of the second limiting section 33 away from the limiting groove 35, a first spacing is maintained between the switch assembly 20 and the trigger 110; when the locking portion 21 is buckled to the first limiting section 32, the locking portion 21 and the second limiting section 33 at least partially overlap in the lateral projection.

[0048] On the basis of the above specific examples, in another specific example, by adding a second limiting section 33, it is possible to make it more convenient and efficient to adjust the locking member 30 to achieve linkage with the switch assembly 20 and the trigger 110. Specifically, in order to make the overall adjustment process efficient and convenient, a limiting card can be set on the mounting housing 10, and the limiting card is used to install an elastic member connected to the switch assembly 20. The elastic member applies an elastic force to the switch assembly 20 to rotate it counterclockwise, that is, an elastic force that causes the switch assembly 20 to move away from the locking member 30. Under the action of the elastic member, the power tool 100 needs to overcome the elastic force to start running, further reducing the accidental occurrence of false triggering. When the lock portion 21 enters the limiting groove 35 and is matched with the first limiting section 32, combined with the elastic force of the elastic member, the lock portion 21 and the first limiting section 32 can be squeezed against each other, further reducing the risk of the lock portion 21 and the first limiting section 32 being separated under the vibration state generated during the processing.

[0049] Preferably, at least one blocking member is provided in the mounting housing 10 ; the locking plate 31 is provided with a mating member 36 for mating with the at least one blocking member; wherein the blocking member and the mating member 36 cooperate to restrict the locking plate 31 from escaping from the mating slot 11 .

[0050] Preferably, there are two mating pieces 36, and the two mating pieces 36 are symmetrically arranged about the locking plate 31 in the transverse direction; the locking piece 30, for example, also includes a reset piece 38, which is clamped in a clamping space 37 formed by the two mating pieces 36, and the reset piece 38 has a deformation force in the transverse direction; wherein, when the blocking piece cooperates with the corresponding mating piece 36, the reset piece 38 cooperates with the corresponding inner wall of the mounting shell 10, and the deformation amount of the reset piece 38 is the first deformation amount; when the blocking piece is separated from the mating piece 36, the reset piece 38 is separated from the corresponding inner wall of the mounting shell 10, and the deformation amount of the reset piece 38 is less than the first deformation amount.

[0051] Preferably, the installation housing 10 is provided with a second installation position 112 and a third installation position 113 in which the switch assembly 20 is clamped; the switch assembly 20, for example, includes a switch body, a first elastic member 121 and a second elastic member 122. The switch body is rotatably connected to the installation housing 10, and the axis direction around which the switch body rotates is coplanar with the moving direction of the locking member 30 in the matching groove 11; the first elastic member 121 is provided between the second installation position 112 and the switch body, and the first elastic member 121 applies a first elastic force to the switch body to make it move away from the first installation position 111; the second elastic member 122 is provided between the third installation position 113 and the switch body, and the second elastic member 122 applies a second elastic force to the switch body to make it move close to the first installation position 111; wherein the first elastic force is greater than the second elastic force.

[0052] Combination Figure 4 Further, since the first elastic force is greater than the second elastic force, and since the first elastic member 121 and the second elastic member 122 are distributed in the vertical direction with respect to the switch assembly 20, the switch assembly 20 has the following characteristics under the combined elastic force applied by the first elastic member 121 and the second elastic member 122: Figure 4 The counterclockwise movement 101 under the viewing angle means that the switch assembly 20 has a tendency to move away from the trigger 110. In combination with the actual use of the power tool 100, the switch assembly 20 is electrically connected to the trigger 110 only when a pressing force is applied to the switch assembly 20 to overcome the effect of the above-mentioned comprehensive elastic force. In combination with the movement of the locking member 30 in the matching groove 11, the stability of the switch assembly 20 being able to switch between the first state and the second state and the safety of the power tool operation can be further improved under the cooperation of the first elastic member 121 and the locking member 30.

[0053] Preferably, the installation shell 10 is in the shape of an elongated strip, and the installation shell 10 is composed of a right shell and a left shell extending along its length direction.

Figure 2-Figure 10 The electric tool 100 includes, for example, a housing assembly, a drive assembly, and a battery pack as provided in the first embodiment. Specifically, the drive assembly is disposed in the installation space of the installation housing 10, and the drive assembly is located at the output end 102 of the installation housing 10; the battery pack is obliquely installed at one end of the installation housing 10 away from the output end 102; wherein a plane for sliding connection of the battery pack is formed on the installation housing 10, and the plane is arranged in a non-planar manner with the axis where the drive shaft of the drive assembly is located.
