[0104] 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 embodiments described 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 those skilled in the art without creative work are within the scope of protection of the present application.

[0105] According to the first aspect of this application, reference Figures 1 to 15 , provides a tool host 100100, including: a shell 110, a driving member 170, a battery 160 and an electromagnetic device 120.

[0106] The shell 110 is formed with a accommodating cavity 11a, and the driving member 170 is used to provide power for driving the tool accessory 200. The battery 160 is arranged in the accommodating cavity 11a and stores and releases the electrical energy required for the motor. The electromagnetic device 120 is used to generate a magnetic field to electrically couple with the electrical energy required to charge the battery 160, wherein the electromagnetic device 120 is detachably connected to the shell 110 so that the tool host 100 has a combined state and a separated state; when the tool host 100 is in the combined state, the accommodating cavity 11a is closed by the electromagnetic device 120 so that the battery 160 can be electrically connected to the driving member 170, and when the tool host 100 is in the separated state, the accommodating cavity 11a is opened by the electromagnetic device 120 so that the battery 160 can be electrically disconnected from the driving member 170.

[0107] Through the above technical solution, the electromagnetic device 120 is used to generate a magnetic field to electrically couple the electric energy required to charge the battery 160, so that the battery 160 can release the electric energy required for the motor to the driving member 170. At the same time, the detachable connection between the electromagnetic device 120 and the shell 110 can also be used to enable the tool host 100 to have a combined state and a separated state. In the combined state, the accommodating cavity 11a is closed by the electromagnetic device 120, so that the battery 160 can be electrically connected to the driving member 170. In the separated state, the accommodating cavity 11a is opened by the electromagnetic device 120, so that the battery 160 can be removed from the accommodating cavity 11a to disconnect the battery 160 from the driving member 170. When the battery 160 is depleted or other accessories that interact with the battery 160 for electric energy fail, resulting in the two being unable to be used normally, there is no need to abandon the tool host 100 as a whole. The operation is simple and convenient, and the safety is higher.

[0108] In some embodiments, the tool host 100 further includes a locking mechanism 130 .

[0109] The locking mechanism 130 is located between the housing 110 and the electromagnetic device 120. Part of the locking mechanism 130 is connected to the housing 110, and part of the locking mechanism 130 is connected to the electromagnetic device 120 to apply force to the housing 110 and the electromagnetic device 120 respectively to keep the housing 110 and the electromagnetic device 120 connected.

[0110] By providing the locking mechanism 130 , it is possible to ensure that the electromagnetic device 120 remains connected to or disconnected from the housing 110 , making it easy to disassemble and operate.

[0111] In some embodiments, the locking mechanism 130 includes a locking member 131 .

[0112] The locking member 131 is rotatably connected to the housing 110 or the electromagnetic device 120 , wherein, under the action of an external force, the locking member 131 has at least a locking position and a releasing position relative to the other of the housing 110 or the electromagnetic device 120 .

[0113] When the locking member 131 is in the locked position, part of the locking member 131 is connected to the other of the housing 110 or the electromagnetic device 120, and when the locking member 131 is in the released position, part of the locking member 131 is disconnected from the other of the housing 110 or the electromagnetic device 120.

[0114] When the locking member 131 is located at the locking position, a portion of the locking member 131 is connected to the housing 110 , and the entire battery 160 device can be stably assembled to the housing 110 .

[0115] When the locking member 131 is in the release position, a portion of the locking member 131 is disconnected from the housing 110 , thereby allowing the electromagnetic device 120 to be removed from the housing 110 with less effort.

[0116] In some embodiments, the locking member 131 is in rotational connection with the electromagnetic device 120;

[0117] Among them, the inner wall surface of the shell 110 has a shell connecting portion 11b, and the part of the locking piece 131 close to the inner wall surface of the shell 110 has a lock connecting portion 1311. When the connection interface of the shell 110 is combined with the lock connecting portion, the relative position of the locking piece 131 and the shell 110 is limited.

[0118] Exemplarily, the locking member 131 can be installed on the electromagnetic device 120 and form a rotational connection with the electromagnetic device 120. When the locking member 131 is in the locked position, the lock connection portion 1311 of the locking member 131 can be combined with the shell connection portion 11b to limit the relative position of the locking member 131 and the shell 110.

[0119] Specifically, the shell connecting portion 11 b may be configured as a groove on the inner wall surface of the housing 110 , and the shape of the end portion of the locking member 131 is adapted to the groove.

[0120] Among them, along the rotation direction of the locking piece 131, the groove has an inclined surface, and the end of the locking piece 131 has an inclined matching surface adapted to the inclined surface. The inclined surface is adapted to the inclined matching surface, so that the locking piece 131 can smoothly enter or exit the groove.

[0121] In some embodiments, the locking mechanism 130 further includes a switch member 132 .

[0122] The switch member 132 is detachably connected to the electromagnetic device 120 .

[0123] The electromagnetic device 120 has a center line. Along a direction parallel to the center line, the switch member 132 can move relative to the electromagnetic device 120 to a first position connected to the locking member 131 to apply a force to the locking member 131 to switch from the release position to the locking position.

[0124] The switch member 132 can be rotatably connected to the electromagnetic device 120, wherein part of the switch member 132 is connected to the locking member 131 along the axial direction of the center line and rotates relative to the electromagnetic device 120 along the radial direction of the center line so that the locking member 131 is located in the locked position.

[0125] By forming a rotational connection between the switch member 132 and the mounting seat 121 and the electromagnetic device 120, part of the switch member 132 can be connected to the locking member 131 along the axial direction of the center line and apply a force to the lock, and the switch member 132 will rotate relative to the electromagnetic device 120 along the radial direction of the center line so that the locking member 131 is located in the locked position, completing the stable installation of the electromagnetic device 120 and the housing 110. When the electromagnetic device 120 needs to be removed from the housing 110, the switch member 132 is rotated in the opposite direction along the radial direction of the center line and disconnected from the mounting seat 121. At this time, the force of the switch member 132 on the locking member 131 is released, so that the locking member 131 can be located in the release position. At this time, the lock of the electromagnetic device 120 by the locking member 131 is released, and the electromagnetic device 120 can be removed from the housing 110 with little effort.

[0126] The switch member 132 rotates to switch the locking member 131 between the locking position and the releasing position.

[0127] In some embodiments, the switch member 132 can be rotated from a first position to a second position relative to the electromagnetic device 120 in a direction perpendicular to the center line so that the locking member 131 remains in the locked position, wherein, in the second position, the electromagnetic device 120 applies a force to the switch member 132 to prevent movement in a direction parallel to the center line.

[0128] By enabling the switch member 132 to rotate relative to the electromagnetic device 120 from a first position to a second position in a direction perpendicular to the center line, in the second position, the electromagnetic device 120 applies a force to the switch member 132 to prevent movement in a direction parallel to the center line, so that the switch member 132 can be stably connected to the electromagnetic device 120 in the second position. At this time, the locking member 131 can be maintained in the locked position, further improving the connection stability between the housing 110 and the electromagnetic device 120.

[0129] In some embodiments, the electromagnetic device 120 includes a through-interface 1231 .

[0130] The through-port 1231 is used for partially passing the switch member 132 and is movable to a first position connected to the locking member 131 , wherein along a projection plane perpendicular to the center line, the projection of the locking member 131 and the projection of the through-port 1231 at least partially overlap.

[0131] By setting the through interface 1231 and the projection of the locking member 131 and the projection of the through structure at least partially overlapping along the projection plane perpendicular to the center line, the switch member 132 applies a force to the locking member 131 at the position of the through interface 1231.

[0132] Exemplarily, the through-interface 1231 is configured as a through-hole along a center line, so that a portion of the switch member 132 can move from a first position to a second position relative to the electromagnetic device 120 along the through-interface 1231 .

[0133] In some embodiments, the electromagnetic device 120 includes a mounting base 121 and a bracket 123 .

[0134] The mounting base 121 is detachably connected to the housing 110 , and the bracket 123 is used to form a through interface 1231 .

[0135] The locking member 131 is rotatably connected to the bracket 123 , and a portion of the switch member 132 is connected to the bracket 123 .

[0136] By setting the mounting base 121 and the bracket 123, wherein the two form a detachable connection, and the bracket 123 is used to form a through interface 1231, at this time, the locking member 131 is rotatably connected to the bracket 123, and part of the switch member 132 is connected to the bracket 123, thereby using the locking member 131 to install the mounting member on the housing 110.

[0137] In some embodiments, the mounting base 121 and the bracket 123 are provided separately;

[0138] At least a portion of the bracket 123 surrounds the mounting seat 121 .

[0139] By arranging the mounting base 121 and the bracket 123 separately, and at least partially arranging the bracket 123 around the mounting base 121, this arrangement can facilitate the connection and disassembly of the mounting base 121 and the bracket 123, and facilitate assembly and disassembly.

[0140] Exemplarily, the bracket 123 includes a main body 1233, which can be connected to the mounting seat 121, and a through interface 1231 is provided on the main body 1233, wherein the main body 1233 can be connected to the mounting seat 121, and the through interface 1231 is provided on the main body 1233, wherein, along the projection plane perpendicular to the center line, the projection of the locking member 131 and the projection of the through interface 1231 are at least partially overlapped. By providing the through interface 1231 on the main body 1233, and along the projection plane perpendicular to the center line, the projection of the locking member 131 and the projection of the through structure are at least partially overlapped, the switch member 132 applies a force to the locking member 131 at the position of the through interface 1231.

[0141] In some embodiments, the switch element 132 includes a switch portion 1321 .

[0142] The switch portion 1321 is adapted to penetrate the interface 1231 to a first position to lift the locking member 131 so that the locking member 131 is located at a locked position.

[0143] By providing the switch portion 1321, a stable force can be applied to the locking member 131, and the operation is convenient. After the switch portion 1321 passes through the interface 1231, the locking member 131 can be lifted up, so that the locking member 131 is located in the locked position. After the switch member 132 rotates around the center line until the switch portion 1321 is connected to the main body 1233, the locking member 131 can be maintained in the locked position, so that the locking member 131 can stably lock the mounting base 121 and the bracket 123.

[0144] At the same time, the switch member 132 is rotated in the opposite direction so that the switch portion 1321 can be rotated to the through-port 1231 and move along the through-port 1231 to completely separate the switch member 132 from the locking member 131 and the bracket 123 .

[0145] In some embodiments, the through-interface 1231 is configured as a through-hole adapted to the switch portion 1321 .

[0146] For example, two through holes may be provided, and the two through holes are symmetrically arranged on the switch member 132 .

[0147] In some other embodiments, the number of through holes may also be set to three or four, and the specific number is subject to the actual setting.

[0148] In some embodiments, the switch element 132 further includes: a switch body 1324 .

[0149] The switch body 1324 is adapted to be connected to the bracket 123 , wherein the switch body 1324 is adapted to rotate about the center line so that the switch portion 1321 can rotate to a second position connected to the bracket 123 , so that the locking member 131 remains in the locked position.

[0150] By connecting the switch body 1324 of the switch component 132 with the bracket 123, and the switch body 1324 rotates around the center line to drive the switch part 1321 to rotate to the second position connected to the bracket 123, the main body 1233 of the bracket 123 can apply a blocking force to the switch body 1324 to ensure a stable connection between the switch component 132 and the bracket 123.

[0151] In some embodiments, a gap 1322 is defined between the switch portion 1321 and the switch body 1324 , and a portion of the bracket 123 is located within the gap 1322 .

[0152] By locating part of the bracket 123 in the gap 1322 , a gap 1322 is defined between the switch portion 1321 and the switch body 1324 1324 , and part of the main body 1233 is located in the gap 1322 , making the installation between the switch member 132 and the bracket 123 more reasonable.

[0153] In some embodiments, the locking mechanism 130 further includes a restoring member 134 .

[0154] The reset member 134 is connected to the bracket 123 and the locking member 131 respectively, wherein part of the reset member 134 acts on the locking member 131 and part of the reset member 134 acts on the bracket 123, so that the locking member 131 has a tendency to move from the locked position to the released position.

[0155] By providing the reset member 134 , the locking member 131 can have a tendency to move from the locking position to the releasing position, which is convenient for operation.

[0156] Specifically, the reset member 134 is constructed as a torsion spring, which forms a rotational connection with the bracket 123. The two ends of the torsion spring are in contact with the bracket 123 and the locking member 131 respectively. When the switch portion 1321 of the switch member 132 rotates back from the second position to the first position and is disconnected from the bracket 123 along the through interface 1231, the lock connection portion 1311 at one end of the locking member 131 will withdraw from the shell connection portion 11b of the shell 110. Under the action of the torsion spring, the locking member 131 will rotate relative to the bracket 123 to the unlocked position, thereby releasing the lock between the shell 110 and the electromagnetic device 120.

[0157] When the switch portion 1321 of the switch member 132 moves to the first position along the through interface 1231, the switch portion 1321 of the switch member 132 will apply a force to the locking member 131, and the lock connection portion 1311 of the locking member 131 will enter the shell connection portion 11b of the shell 110. At this time, the locking member 131 will rotate to the locked position relative to the bracket 123, completing the locking of the shell 110 and the electromagnetic device 120, and the switch member 132 will rotate around the center line from the first position to the second position. At this time, the main body 1233 of the bracket 123 will continuously enter the gap 1322, thereby allowing the locking member 131 to remain in the locked position.

[0158] In some embodiments, the bracket 123 has a branch connection portion 1232 , and the mounting seat 121 has a seat connection portion 1211 .

[0159] The branch connection portion 1232 is used to connect with the mounting seat 121 , and the seat connection portion 1211 is used to cooperate with the branch connection portion 1232 .

[0160] When the branch connection portion 1232 is adapted and combined with the seat connection portion 1211 , the relative position of the bracket 123 and the mounting seat 121 is restricted.

[0161] By providing the branch connection portion 1232 and the seat connection portion 1211 , a stable and detachable connection between the bracket 123 and the mounting seat 121 is achieved.

[0162] In some embodiments, the branch connection portion 1232 and the seat connection portion 1211 include a snap-fit ​​structure or a slot structure.

[0163] Exemplarily, the branch connection portion 1232 is provided with a snap-fit ​​structure, and the seat connection portion 1211 is provided with a slot structure, so as to facilitate molding.

[0164] In some embodiments, the bracket 123 further includes a limiting portion 1234 .

[0165] The limiting portion 1234 is provided on the bracket 123 , wherein the limiting portion 1234 is located at one side of the penetrating interface 1231 and is used to limit the switch member 132 from rotating around the center line.

[0166] Exemplarily, the limiting portion 1234 is provided on the main body 1233 of the bracket 123 , wherein the limiting portion 1234 is located on one side of the penetrating interface 1231 and is used to limit the switch member 132 from rotating around the center line.

[0167] By setting the limiting portion 1234, when the switch portion 1321 rotates radially around the center line, the limiting portion 1234 can limit the switch member 132 from continuing to rotate around the center line. When the switch portion 1321 rotates to abut against the limiting portion 1234, it indicates that the rotation is in place, avoiding excessive rotation of the switch member 132, so that the switch portion 1321 and the locking member 131 are stably connected.

[0168] In some embodiments, the tool host 100 further includes an unlocking member 140 .

[0169] The unlocking member 140 has an unlocking interface 141 , and the switch member 132 further has a driving interface 1323 .

[0170] The driving interface 1323 is adapted to be connected with the unlocking interface 141 , wherein when the driving interface 1323 is adapted to be combined with the adapting interface, the relative positions of the switch member 132 and the unlocking member 140 are limited.

[0171] By setting an unlocking interface 141 on the unlocking member 140 and an adapting connection part with the driving interface 1323 of the switch member 132, a rotational force can be applied to the switch member 132 through the unlocking member 140 so that the switch member 132 can rotate around the center line, further improving the convenience of operation. In addition, setting a specific unlocking member 140 can prevent the switch member 132 from being misoperated, which may cause the electromagnetic device 120 and the housing 110 to be misdisassembled.

[0172] For example, the driving interface 1323 may be configured as a groove, and the unlocking interface 141 may be configured as a protrusion adapted to the groove.

[0173] In some embodiments, the tool host 100 further includes a primary coil, and the electromagnetic device 120 further includes a secondary coil 122 .

[0174] The primary coil is disposed on the unlocking member 140 , and the secondary coil 122 is used to generate a magnetic field to electrically couple with the electrical energy required to charge the battery 160 ;

[0175] The primary coil is electrically connected to an external power source to form a magnetic coupling with the secondary coil 122 , so that the secondary coil 122 is electrically coupled to the electrical energy required for charging the battery 160 .

[0176] The primary coil is set on the unlocking part 140, and a magnetic coupling can be formed between the primary coil and the secondary coil 122, completing the voltage transformation between the primary coil and the secondary coil 122. After the coil generates a magnetic field again, it can be electrically coupled with the electric energy required to charge the battery 160, thereby charging the battery 160 in the accommodating cavity 11a.

[0177] This arrangement enables the unlocking member 140 to function as an adapter after the primary coil is provided, and also to function as a switch of the switch member 132 , thereby achieving reuse of the unlocking member 140 and simplifying the structure.

[0178] Exemplarily, the switch member 132 has a storage space, and part of the unlocking member 140 can be inserted into the storage space. At this time, the driving interface 1323 and the unlocking interface 141 will be adapted to connect, completing the physical connection between the unlocking member 140 and the electromagnetic device 120, and then the primary coil of the unlocking member 140 is electrically connected to the external power supply, which can form a magnetic coupling with the electromagnetic device 120.

[0179] In some embodiments, the tool host 100 further includes a sealing structure 150 located between the mounting base 121 and the electromagnetic device 120 .

[0180] By providing the sealing structure 150 , the sealing between the mounting seat 121 and the electromagnetic device 120 can be completed, thereby ensuring the sealing effect of the accommodating cavity 11 a.

[0181] Exemplarily, the sealing structure 150 may be configured as a rubber ring.

[0182] In the present application, in some embodiments, the mounting seat 121 is constructed as an annular groove with a groove bottom, and a connecting column is provided at the center position of the mounting seat 121, and the connecting column has a preset space, and the preset space is for the switch component 132 to pass through and form a connection with the bracket 123. The bracket 123 has a central space, and the central space is for the connecting column to pass through, so that the mounting seat 121, the bracket 123 and the switch component 132 form a connection relationship in which they are arranged in sequence.

[0183] The outer wall surface of the annular groove of the mounting seat 121 is connected to the inner wall surface of the housing 110, and a sealing structure 150 is provided between the two. The inner surface of the annular groove of the mounting seat 121 has a mounting seat 121 connection interface, and a bracket 123 connection interface is provided on the bracket 123. When the seat connection portion 1211 and the branch connection portion 1232 are combined, the relative position of the bracket 123 and the mounting seat 121 is restricted.

[0184] Specifically, the bracket 123 overlaps with the mounting base 121. By setting the bracket 123 for connection to the secondary coil 122, and along the projection plane of the center line, the bracket 123 overlaps with the mounting base 121, ensuring that the secondary coil 122 is stably mounted on the mounting base through the bracket 123.

[0185] Exemplarily, the bracket 123 may be configured as an I-shaped structure in cross section, and the overall structure of the bracket 123 may be annular, so that the magnetic body can be wound around the bracket 123 while forming a stable connection with the mounting base 121 .

[0186] The driving member 170 in the present application is configured as a motor.

[0187] According to a second aspect of the present application, a tool 10 is provided, comprising: a tool accessory 200 and the tool host 100 as described above.

[0188] The tool 10 has all the beneficial effects of the above-mentioned tool host 100, which will not be described in detail in this application.

[0189] In some embodiments, the tool is an electric toothbrush that is easy to use and can replace and recharge the battery 160 as needed.

[0190] The toothbrush of the present application does not need to be provided with a separate base with an electromagnetic device 120. If the battery 160 or the motor fails alone, there is no need to discard the entire thing, thus avoiding waste of resources. At the same time, the waterproof sealing effect is good, and the internal body 1233 will not be damaged by water ingress due to a loose base. Therefore, the battery 160 can be conveniently disassembled and recycled, thus avoiding environmental pollution and facilitating power outages to avoid dangers such as fire.

[0191] According to a third aspect of the present application, a vehicle is further provided, comprising the above tool host 100 or the above tool 10 .

[0192] The vehicle has all the beneficial effects of the above-mentioned tool host 100, which will not be described in detail in this application.

[0196] The embodiments, implementation methods and related technical features of the present application can be combined and replaced with each other without conflict.
