Description

Technical Field

[0001] The utility model relates to the technical field of electric toothbrushes, in particular to a buckle device, a core bracket and an electric toothbrush. Background Art

[0002] An electric toothbrush primarily consists of a body and a movement. The body is the housing, while the movement includes a movement bracket, a motor, and a battery mounted within it. The movement bracket typically connects to the body via a clip. Early in electric toothbrush production, the movement needed to be disassembled from the body for testing or rework. Existing techniques typically require a specific jig to disassemble the movement from the body. Without a jig, the clips typically break, rendering the product scrapped.

[0003] However, jigs are large and available in limited quantities, making them inconvenient to use. Furthermore, jigs are expensive to manufacture, and improper operation can cause the buckle to break, resulting in wasted material and increased costs. Therefore, using jigs to remove buckles is not only inconvenient but also expensive. Utility Model Content

[0004] In view of this, the utility model provides a buckle device, a movement bracket and an electric toothbrush to solve the problem of inconvenient operation and high cost of removing the buckle by a jig.

[0005] In the first aspect, the utility model provides a snap-fit ​​device, comprising: two snap-fit ​​legs, one end of each snap-fit ​​leg being suitable for being fixedly connected to a bracket body, and a snap-fit ​​portion protruding from the surface of each snap-fit ​​leg being constructed on a side of each snap-fit ​​leg away from the other snap-fit ​​leg; a connecting piece connected between the two snap-fit ​​legs, the connecting piece being in a bent shape, and the connecting piece being suitable for bending and deforming under the action of an external force and pulling the two snap-fit ​​legs closer to each other, thereby driving the two snap-fit ​​portions to move toward each other.

[0006] Beneficial effect: The two legs are connected by arranging a connecting piece between the two legs, and the connecting piece is arranged in a bent shape so that the connecting piece can bend and deform under the action of external force, thereby pulling the ends of the two legs away from the bracket body closer to each other, and then the clamping parts on the legs move with the legs, so that the two clamping parts are close to each other, and then the clamping parts originally clamped in the clamping slot on the shell can be disengaged from the clamping slot, thereby realizing the disassembly of the snap device and the shell, that is, realizing the disassembly of the movement bracket and the shell. The entire disassembly process only requires applying force to the connecting piece, and no jig is required to assist, which simplifies the disassembly process and is easy to operate. It effectively avoids the problem of damage to the clamping structure due to improper operation of the jig during disassembly, thereby reducing costs.

[0007] In an optional embodiment, the connecting piece is connected to the end of the clamping leg away from the bracket body;

[0008] And / or, the connecting piece is bent toward a direction close to the bracket body.

[0009] Beneficial effect: By setting a connecting piece connected to the end of the clamping leg away from the bracket body, the connecting piece is farther away from the end where the clamping leg is connected to the bracket body.

[0012] In an optional embodiment, the positioning hole is a through hole, and the snap-fit ​​device further includes a positioning portion, which is suitable for being fixedly connected to the bracket body, and a threaded hole is provided on the positioning portion. The distance between the connecting piece and the positioning portion is suitable for being adjusted by a threaded connector, and the threaded connector is used to pass through the positioning hole and then threadably engage with the threaded hole.

[0013] Beneficial effect: By setting the positioning part and the first end of the clamping leg to be relatively fixed, and opening a threaded hole on the positioning part, it is convenient to connect the connecting piece and the positioning part through a threaded connector, and further adjust the distance between the connecting piece and the positioning part by the degree of screwing of the threaded connector in the threaded hole on the positioning part, so as to apply a force toward the bracket body to the connecting piece through the threaded connector, pull the connecting piece toward the direction of the bracket body, and thus pull the two clamping legs closer to each other through the connecting piece, thereby realizing the disassembly of the clamping part; the threaded connector is threadedly connected to the positioning part, and during the process of removing the movement bracket from the shell, the two clamping legs always remain relatively fixed, the clamping legs will not rebound, and the stability is better, thereby ensuring the smooth progress of the entire disassembly process.

[0014] In an optional embodiment, the positioning portion is columnar.

[0015] Beneficial effects: The columnar structure is relatively stable, easy to process, and can provide sufficient design space for the threaded hole.

[0016] In an optional embodiment, the connecting piece includes two first connecting parts, two inclined parts and one second connecting part, each of the first connecting parts is fixedly connected to one of the clamping legs, one end of each first connecting part away from the clamping leg is connected to one of the inclined parts, the inclined parts are arranged at an angle to the first connecting part, the second connecting part is connected between the two inclined parts, and the positioning hole is provided on the second connecting part.

[0017] Beneficial effect: The connecting piece is bent toward the bracket body, and by setting a positioning hole on the second connecting part, when the threaded connecting piece is connected between the connecting piece and the positioning part, a force is applied to the connecting piece toward the direction of the bracket body by tightening the threaded connecting piece, which facilitates pulling the connecting piece to bend and deform. The structure is simple and the operation is convenient.

[0018] In an optional embodiment, the clamping leg includes a first clamping segment and a second clamping segment, the first end of the first clamping segment is suitable for being fixedly connected to the bracket body, the second end of the first clamping segment is fixedly connected to one end of the second clamping segment, the first clamping segment is arc-shaped, the distance between the second ends of the two first clamping segments is greater than the distance between the first ends of the two first clamping segments, and the extension direction of the second clamping segment is perpendicular to the end face of the bracket body.

[0019] Beneficial Effects: By configuring the locking leg to include a first locking segment and a second locking segment that are fixedly connected, with the first locking segment being arcuate and the second locking segment being linear, the locking leg is bent as a whole, which helps ensure elastic deformation of the locking leg during assembly and disassembly, thereby improving the reliability of the locking device. The second locking segment is linear, and the connecting piece is connected to the second locking segment, facilitating the movement of the second locking segment, thereby facilitating the retraction of the locking device.

[0020] In an optional embodiment, the clamping portion has a first clamping surface and a second clamping surface, the first clamping surface is formed on the side of the clamping portion away from the bracket body, the first clamping surface is parallel to the end face of the bracket body, and the second clamping surface is formed on the side of the clamping portion facing the bracket body, and the second clamping surface is an inclined surface.

[0021] Beneficial effect: By setting the side of the clamping part close to the bracket body as a first clamping surface with an inclined surface, and the side away from the bracket body as a second clamping surface parallel to the end face of the bracket body, on the one hand, the inclined surface provides guidance during the installation process of the movement bracket and the shell, so that the clamping part can slide smoothly into the slot; on the other hand, after the clamping part enters the slot, the second flat clamping surface abuts against the side wall of the slot, preventing the clamping part from falling out of the slot when there is no external force, thereby increasing the reliability of the clamping.

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0035] The following combination Figures 1 to 7 , describing the embodiments of the present utility model.

[0036] According to an embodiment of the present invention, a snap-fit ​​device is provided, comprising: two clamping legs 1 and a connecting piece 2. One end of each clamping leg 1 is adapted to be fixedly connected to a bracket body 4. Each clamping leg 1 is configured with a clamping portion 110 protruding from the surface of the clamping leg 1 on a side facing away from the other clamping leg 1. The connecting piece 2 is connected between the two clamping legs 1 and is bent. The connecting piece 2 is adapted to bend and deform under the action of an external force, pulling the two clamping legs 1 toward each other, thereby driving the two clamping portions 110 toward each other. The bracket body 4 is the main body of the movement bracket.

[0037] The snap-fit ​​device of this embodiment is used to connect the two legs 1 by setting a connecting piece 2 between the two legs 1. By setting the connecting piece 2 in a bent shape, the connecting piece 2 can be bent and deformed under the action of an external force, thereby pulling the ends of the two legs 1 away from the bracket body 4 closer to each other, and then the clamping part 110 on the leg 1 moves with the leg 1, so that the two clamping parts 110 are close to each other, and then the clamping part 110 originally clamped in the clamping groove 501 on the shell 5 can be disengaged from the clamping groove 501, realizing the disassembly of the snap-fit ​​device and the shell 5, that is, realizing the disassembly of the movement bracket and the shell 5. The entire disassembly process only requires applying a force to the connecting piece 2, without the assistance of a jig, which simplifies the disassembly process and is easy to operate. It effectively avoids the problem of damage to the clamping structure due to improper operation of the jig during disassembly, thereby reducing costs. Among them, the external force can be along Figures 6 and 7The middle arrow refers to the pressure in the direction of "C" from the connecting piece 2 to the direction close to the bracket body 4; the external force can also be along Figures 6 and 7 The middle arrow indicates the pulling force in the opposite direction of “C”, which is directed from the connecting piece 2 away from the bracket body 4 .

[0038] It should be noted that the snap-fit ​​device is a part of the movement bracket, which is installed inside the shell 5 of the electric toothbrush and is snap-fitted to the shell 5 through the snap-fit ​​device. Specifically, the snap-fitting portion 110 on the clamping leg 1 protrudes from the surface of the clamping leg 1. When the clamping portion 110 is snapped into the clamping groove 501 on the inner wall of the shell 5, the movement bracket and the shell 5 are snap-fitted. The clamping leg 1 is a narrow strip with an elastic structure. The first ends of the two clamping legs 1 are fixedly connected to the bracket body 4, and the first ends of the two clamping legs 1 are relatively fixed. 1, the other end away from the bracket body 4 is a movable end, which can be moved relative to the first end of the clamping leg 1 under the action of an external force, so that the clamping leg 1 is elastically deformed. By applying an external force, the two clamping legs 1 are brought closer to each other, and the clamping portion 110 can be disengaged from the clamping groove 501, thereby realizing the disassembly of the movement bracket and the shell 5; the connecting piece 2 is bent to ensure that the connecting piece 2 can be bent and deformed under the action of an external force. After the connecting piece 2 is bent, the straight-line distance between its two ends is reduced, thereby pulling the two clamping legs 1 closer to each other.

[0039] In one embodiment, the connecting piece 2 is connected to the end of the clamping leg 1 away from the bracket body 4. The first end of the clamping leg 1 close to the bracket body 4 is fixedly connected to the bracket body 4, and the end of the clamping leg 1 away from the bracket body 4 is a movable end. By providing the connecting piece 2 connected to the end of the clamping leg 1 away from the bracket body 4, the connecting piece 2 is farther away from the end of the clamping leg 1 connected to the bracket body 4. When a small external force is applied to the connecting piece 2, the movable end of the clamping leg 1 can be driven to move, making operation more convenient. Specifically, the connecting piece can be connected to the end face of the clamping leg 1 farthest away from the bracket body 4, or it can be connected to a position near the end face, that is, at a small distance from the end face.

[0040] In one embodiment, the connecting piece 2 is bent toward the direction close to the bracket body 4, and the external structure applies pressure to the connecting piece 2 toward the bracket body 4. The pressure presses down the connecting piece 2, which can cause the connecting piece 2 to deform. The operation is simple. Figures 6 and 7 The middle arrow indicates the force in the “C” direction directed from the connecting piece 2 toward the direction close to the bracket body 4 .

[0041] It is understood that, as an alternative embodiment, the connecting piece 2 can also be bent in a direction away from the bracket body 4. Then, by applying a pulling force away from the bracket body 4 to the connecting piece 2 through the external structure, the bending deformation of the connecting piece 2 can also be achieved, thereby driving the clamping leg 1 to move. Figures 6 and 7The middle arrow indicates the force in the opposite direction of “C”, which is directed from the connecting piece 2 away from the bracket body 4 .

[0042] In one embodiment, a positioning hole is provided on the connecting piece 2. By providing the positioning hole on the connecting piece 2, the external structure can be inserted into the positioning hole to apply a force to the connecting piece 2. The positioning hole improves positioning accuracy, facilitates positioning of the external structure when applying a force to the connecting piece 2, and ensures the stability of the external structure during the process of applying the force to the connecting piece 2. Preferably, the positioning hole is located at the center of the connecting piece 2.

[0043] In one embodiment, the positioning hole is a through hole, and the snap-fit ​​device also includes a positioning portion 3, which is suitable for being fixedly connected to the bracket body 4. A threaded hole is provided on the positioning portion 3, and the distance between the connecting piece 2 and the positioning portion 3 is suitable for being adjusted by a threaded connector 6. The threaded connector 6 can optionally pass through the positioning hole and then be threadedly engaged with the threaded hole.

[0044] It should be noted that the first end of the clamping leg 1 is fixedly connected to the bracket body 4, and the positioning part 3 is fixedly connected to the bracket body 4, so the positioning part 3 is relatively fixed to the first end of the clamping leg 1. By setting the positioning part 3 to be relatively fixed to the first end of the clamping leg 1 and opening a threaded hole on the positioning part 3, it is convenient to connect the connecting piece 2 and the positioning part 3 through the threaded connection 6, and further adjust the distance between the connecting piece 2 and the positioning part 3 by the degree of screwing of the threaded connection 6 in the threaded hole on the positioning part 3, so as to apply a force toward the bracket body 4 to the connecting piece 2 through the threaded connection 6, pull the connecting piece 2 toward the direction of the bracket body 4, and thereby pull the two clamping legs 1 closer to each other through the connecting piece 2, thereby realizing the disassembly of the clamping part. Among them, by rotating the threaded connector 6, the force applied to the connecting piece 2 can be gradually increased until the clamping part 110 is disengaged from the clamping slot 501. At this time, the threaded connector 6 is threadedly connected to the positioning part 3. During the process of removing the movement bracket from the shell 5, the two clamping legs 1 always remain relatively fixed, the clamping legs 1 will not rebound, and the stability is better, ensuring the smooth progress of the entire disassembly process.

[0045] In other embodiments, the positioning hole may be a blind hole without the positioning portion 3, and the external structure only needs to abut against the blind hole. The external structure may be a slender structure with a tip such as a screwdriver or an awl, so that the tip can fit in the positioning hole and improve positioning accuracy.

[0046] When the positioning hole is a through hole, in one embodiment, the threaded connector 6 is a screw, such as a screw, bolt, or the like. When the movement bracket needs to be disassembled, the threaded connector 6 is passed through the positioning hole and then into the threaded hole. Tightening the threaded connector 6 with a screwdriver applies pressure to the connecting piece 2 toward the bracket body 4. Tightening the threaded connector 6 causes the two clamping legs 1 to retract inward, thereby disengaging the clamping portion 110 on the clamping leg 1 from the clamping slot 501, thereby achieving disassembly of the clamping device and the housing 5, thereby facilitating removal of the movement bracket from the housing 5. Both screws and screwdrivers are relatively common, easy to operate, and low in cost.

[0047] In addition, in other embodiments, the threaded connector 6 can also be a threaded portion on an electric screwdriver with threaded threads. When the movement bracket needs to be disassembled, the electric screwdriver is passed through the positioning hole, and then the threaded thread is inserted into the threaded hole. By powering the electric screwdriver, the threaded thread can be rotated, thereby achieving the screwing of the threaded thread into the threaded hole. Similarly, pressure can be provided to the connecting piece 2 toward the bracket body 4, thereby deforming the connecting piece 2, driving the two clamping legs 1 to retract inward, and the clamping portion 110 is disengaged from the clamping groove 501, thereby achieving the disassembly of the buckle device and the shell 5, and facilitating the removal of the movement bracket from the shell 5. As a simple jig, the electric screwdriver with threaded threads is relatively common, low in cost, easy to operate, and can also increase the speed of disassembly and assembly.

[0048] It should be noted that when the movement bracket and the housing 5 are assembled together, Figure 7 As shown, the distance L1 between the connecting piece 2 and the positioning portion 3 is 3.5mm-5.5mm, preferably, L1 is 4mm; the distance L2 of the clamping portion 110 extending into the clamping slot 501 is 1.2mm-1.5mm, preferably, L2 is 1.3mm.

[0049] In one embodiment, the positioning portion 3 is cylindrical. The cylindrical structure is relatively stable, easy to process, and can provide sufficient design space for the threaded hole.

[0050] Preferably, the positioning portion 3 is cylindrical, which can reduce the material usage as much as possible and save costs.

[0051] In one embodiment, the connecting piece 2 includes two first connecting parts 201, two inclined parts 202 and a second connecting part 203, each first connecting part 201 is fixedly connected to a clamping leg 1, and one end of each first connecting part 201 away from the clamping leg 1 is connected to an inclined part 202, the inclined part 202 is arranged at an angle to the first connecting part 201, the second connecting part 203 is connected between the two inclined parts 202, and a positioning hole is provided on the second connecting part 203. The two ends of the second connecting portion 203 are each connected to one end of an inclined portion 202 away from the first connecting portion 201, and the first connecting portion 201, the inclined portion 202, the second connecting portion 203, the inclined portion 202, and the first connecting portion 201 are connected in sequence to form a connecting piece 2, wherein the second connecting portion 203 is parallel to the first connecting portion 201 and is not on the same plane, and the first connecting portion 201 and the second connecting portion 203 are transitionally connected through the inclined portion 202, and the inclined portion 202 is set at an angle to the first connecting portion 201 and the second connecting portion 203, so that the connecting piece 2 is bent toward the bracket body 4, and then by setting a positioning hole on the second connecting portion 203, when the threaded connection 6 is connected between the connecting piece 2 and the positioning portion 3, a force is applied to the connecting piece 2 toward the direction of the bracket body 4 by tightening the threaded connection 6, which facilitates pulling the connecting piece 2 to bend and deform. The structure is simple and the operation is convenient.

[0052] In one embodiment, the clamping leg 1 includes a first clamping segment 101 and a second clamping segment 102. The first end of the first clamping segment 101 is adapted to be fixedly connected to the bracket body 4, and the second end of the first clamping segment 101 is fixedly connected to one end of the second clamping segment 102. The first clamping segment 101 is arc-shaped, and the distance between the second ends of the two first clamping segments 101 is greater than the distance between the first ends of the two first clamping segments 101. The extension direction of the second clamping segment 102 is perpendicular to the end face of the bracket body 4. The first and second ends of the first clamping segment 101 are opposite ends of the first clamping segment 101; one end of the second clamping segment 102 is fixedly connected to the first clamping segment 101 and the other end is the movable end of the clamping leg 1; the second clamping segment 102 is smoothly transitioned to the first clamping segment 101; and the end face of the bracket body 4 refers to the end face on which the clamping leg 1 is provided.

[0053] By configuring the clamping leg 1 to include a first clamping segment 101 and a second clamping segment 102 that are fixedly connected, with the first clamping segment 101 being curved and the second clamping segment 102 being linear, the clamping leg 1 is bent as a whole, which helps ensure elastic deformation of the clamping leg 1 during assembly and disassembly, thereby improving the reliability of the clamping device. The second clamping segment 102 is linear, and the connecting piece 2 is connected to the second clamping segment 102, facilitating the movement of the second clamping segment 102, thereby facilitating the retraction of the clamping device.

[0054] In one embodiment, the clamping portion 110 has a first clamping surface 111 and a second clamping surface 112. The first clamping surface 111 is formed on the side of the clamping portion 110 away from the bracket body 4 and is parallel to the end face of the bracket body 4. The second clamping surface 112 is formed on the side of the clamping portion 110 facing the bracket body 4 and is inclined. By providing the first clamping surface 111 as an inclined surface on the side of the clamping portion 110 close to the bracket body 4 and the second clamping surface 112 as a parallel surface to the end face of the bracket body 4 on the side away from the bracket body 4, the inclined surfaces provide guidance during the installation of the movement bracket and the housing 5, facilitating the smooth sliding of the clamping portion 110 into the slot 501. Furthermore, after the clamping portion 110 enters the slot 501, the flat second clamping surface 112 abuts against the sidewall of the slot 501, preventing the clamping portion 110 from falling out of the slot 501 in the absence of external force, thereby increasing the reliability of the clamping connection. The side wall of the clamping slot 501 that contacts the second clamping surface 112 is flat. When the clamping portion 110 is clamped with the clamping slot 501 , the side wall abuts against the second clamping surface 112 .

[0055] According to an embodiment of the present invention, another aspect is provided, which includes a support body 4 and the aforementioned snap-fit ​​device. The snap-fit ​​device is fixedly connected to one end of the support body 4. Specifically, the snap-fit ​​device is fixedly connected to the end surface of one end of the support body 4.

[0056] In one embodiment, the movement bracket is constructed with a first accommodating cavity 401 and a second accommodating cavity 402 spaced apart from each other. The first accommodating cavity 401 is suitable for installing a motor, and the second accommodating cavity 402 is suitable for installing a battery. The battery provides power for the motor. The output end of the motor is connected to the toothbrush head, and the motor drives the toothbrush head to vibrate.

[0057] According to an embodiment of the present invention, on the other hand, an electric toothbrush is also provided, comprising: a shell 5 and the above-mentioned movement bracket. The shell 5 is in the shape of a shell, and has an inner cavity. A card slot 501 is constructed on the inner wall of the shell 5; the movement bracket is installed in the inner cavity of the shell 5, and the clamping portion 110 in the clamping device is detachably engaged with the card slot 501. Specifically, the shell 5 has a first open end 510 and a second open end 520. The opening of the first open end 510 is smaller than the opening of the second open end 520. The first open end 510 is suitable for cooperating with the toothbrush head part. The movement bracket is installed into the shell 5 from the second open end 520. The clamping portion 110 on the movement bracket is detachably engaged with the card slot 501 on the shell 5, thereby realizing a detachable connection between the movement bracket and the shell 5.

[0058] The buckle device of this embodiment drives the clamping leg 1 to retract inward by tightening the screw to press down the connecting piece 2, and then the movement can be extracted from the shell 5. The movement can be disassembled by tightening the screws by an ordinary screwdriver without the assistance of a jig, which simplifies the traditional disassembly method that requires the use of a jig to shrink the buckle structure before removing the movement bracket, avoids the problem of the jig breaking the buckle due to improper operation, and is easy to operate and low in cost.
