[0014] The motor bracket provided in the first aspect of this application is used in an electronic device. The electronic device includes a housing, and a motor and the motor bracket are disposed inside the housing. The motor bracket is composed of a rigid rubber end plate, a flexible rubber end plate, two rigid rubber arc plates, and two flexible rubber arc plates. One end of the two rigid rubber arc plates is disposed on the rigid rubber end plate opposite to each other and spaced apart from each other. The flexible rubber end plate is attached to the rigid rubber end plate. One end of the two flexible rubber arc plates is disposed on the flexible rubber end plate opposite to each other and spaced apart from each other. The two flexible rubber arc plates are respectively attached to the inner sides of the two rigid rubber arc plates. A first through groove extending towards the central axis of the rigid rubber arc plate is opened on the opposite two sides of the rigid rubber arc plate. The first through groove penetrates the rigid rubber arc plate in the thickness direction. An accommodating space is formed between the two flexible rubber arc plates. Corresponding through holes are opened on the rigid rubber end plate and the flexible rubber end plate respectively. In practical applications, the end of the motor with the output shaft can be inserted into the receiving space, so that the two soft rubber arc plates cover the opposite sides of the motor respectively, and the output shaft of the motor passes through the receiving space through the two through holes. Under the pressure of the motor in the receiving space, the two soft rubber arc plates will move in opposite directions. At the same time, since each hard rubber arc plate has two first through slots, each hard rubber arc plate has a certain degree of elasticity. Therefore, the two hard rubber arc plates will move in opposite directions under the pressure of the two soft rubber arc plates. However, the outer sides of the two hard rubber arc plates abut against the inner sidewall of the housing, which restricts the movement of the two hard rubber arc plates in opposite directions. This restricts the movement of the two soft rubber arc plates in opposite directions, so that the motor, the two soft rubber arc plates, the two hard rubber arc plates and the inner sidewall of the housing are pressed against each other. In this way, the motor can be firmly clamped in the receiving space between the two soft rubber arc plates, and the vibration generated by the motor during operation will be canceled out by the elasticity of the two soft rubber arc plates and the two hard rubber arc plates. Therefore, the motor bracket of this application provides better fixation for the motor, making it less prone to loosening. It can effectively reduce the noise of the motor during operation and the vibration of the whole machine. At the same time, the motor bracket does not require the use of clips, screws and other parts, making assembly simpler and the cost lower.

It is an indispensable power source in electronic devices, such as robot vacuum cleaners, electric shavers, electric toothbrushes, hair dryers, and drones. In related technologies, motors within electronic devices are typically secured by brackets. However, existing brackets are not ideal for securing motors, allowing them to loosen and exacerbating noise and vibration during operation. Utility Model Content
[0003] This application provides a motor bracket, a drive device, and an electronic device, which aims to solve the problem of excessive noise during motor operation in the related art, which exacerbates the vibration of the entire machine.
[0004] To address the aforementioned drawbacks in related technologies, this application provides a motor bracket for use in an electronic device. The electronic device includes a housing and a motor housed within the housing. The motor bracket, located within the housing, includes a rigid plastic end plate, a flexible plastic end plate, two rigid plastic arc-shaped plates, and two flexible plastic arc-shaped plates. One end of each of the two rigid plastic arc-shaped plates is positioned opposite to and spaced apart from each other on the rigid plastic end plate. The flexible plastic end plate is attached to the rigid plastic end plate. One end of each of the two flexible plastic arc-shaped plates is positioned opposite to and spaced apart from each other on the flexible plastic end plate. The two flexible plastic arc-shaped plates are respectively attached to the inner sides of the two rigid plastic arc-shaped plates. A first through-groove extending towards the central axis of the rigid plastic arc-shaped plate is formed on each of the opposite sides of the rigid plastic arc-shaped plate. The first through-groove penetrates the rigid plastic arc-shaped plate in the thickness direction, forming an accommodating space between the two flexible plastic arc-shaped plates. Corresponding through holes are formed on the rigid plastic end plate and the flexible plastic end plate. Specifically, the receiving space is used to accommodate the motor; two through holes are used for the output shaft of the motor to pass through the receiving space; two soft rubber arc plates are used to press between the two hard rubber arc plates and the motor respectively, and two hard rubber arc plates are used to press between the two soft rubber arc plates and the inner side wall of the housing respectively, so as to clamp the motor in the receiving space.
[0005] In some implementation schemes, the two first through slots on the same rigid rubber arc plate are opposite to each other and spaced apart, and each first through slot is bent and extended, with the bending direction of each first through slot facing the rigid rubber end plate.
[0006] In some implementation schemes, the distance between the location of the first through groove on the side of the rigid plastic curved plate and the end of the rigid plastic curved plate away from the rigid plastic end plate is the first distance, and the distance between the location of the first through groove on the side of the rigid plastic curved plate and the other end of the rigid plastic curved plate is the second distance, and the first distance is less than the second distance.
[0007] In some implementation schemes, the two opposite sides of the soft rubber arc plate are respectively provided with a second through groove extending towards the central axis of the soft rubber arc plate and penetrating the soft rubber arc plate in the thickness direction; in the soft rubber arc plate and the hard rubber arc plate that are attached to each other, the second through groove on the same side is aligned with the first through groove and has the same structure.
[0008] In some implementation schemes, the inner wall of the rigid rubber arc plate is provided with a positioning groove extending along the length direction, and the outer side of the soft rubber arc plate is formed with a positioning rib extending along the length direction; in the soft rubber arc plate and the rigid rubber arc plate that are in contact, the positioning rib is inserted into the positioning groove and is pressed against the groove wall.
[0009] In some implementation schemes, each soft rubber arc plate has a limiting rib extending along the length direction on its inner side, and the outer side wall of the motor has two limiting grooves extending along the length direction and symmetrical with respect to the central axis of the motor. The two limiting ribs are used to insert into the two limiting grooves respectively and to press against the groove walls of the two limiting grooves respectively.
[0010] In some implementation schemes, each rigid rubber arc plate has guide ribs extending along the length direction on its outer side, and the inner side wall of the housing has two guide grooves extending along the length direction and symmetrical with respect to the central axis of the housing. The two guide ribs are used to insert into the two guide grooves respectively and to press against the groove walls of the two guide grooves respectively.
[0011] In some implementations, at least one first fixing hole is provided on both the rigid and flexible end plates, and at least one second fixing hole is provided on the end face of the motor with the output shaft. The at least one second fixing hole is used to align with the at least one first fixing hole when the motor is located in the receiving space. Based on this, in addition to the structure given above, the motor bracket also includes at least one fastener, which is used to be inserted into the at least one first fixing hole and the at least one second fixing hole respectively when the motor is located in the receiving space, so as to fix the motor in the receiving space.
[0012] The second aspect of this application provides a driving device used in an electronic device. The electronic device includes a housing, and the driving device is disposed in the housing. It includes a motor, a power supply, a power supply bracket, and the motor bracket provided in the first aspect of this application. One end of the motor with an output shaft is inserted into a receiving space. The output shaft of the motor passes through two through holes and exits the receiving space. An inwardly recessed insertion hole is opened on the end face of one end of the power supply bracket. The end of the motor opposite to the output shaft is inserted into the insertion hole. An inwardly recessed placement groove is opened on the outer side wall of the power supply bracket and is adjacent to the other end of the power supply bracket. The power supply is disposed in the placement groove and is electrically connected to the motor. The motor, the power supply bracket, and the inner side wall of the housing are pressed against each other.
[0013] A third aspect of this application provides an electronic device, which includes a housing and a driving device provided in the second aspect of this application, the driving device being disposed within the housing.
[0014] The motor bracket provided in the first aspect of this application is used in an electronic device. The electronic device includes a housing, and a motor and the motor bracket are disposed inside the housing. The motor bracket is composed of a rigid rubber end plate, a flexible rubber end plate, two rigid rubber arc plates, and two flexible rubber arc plates. One end of the two rigid rubber arc plates is disposed on the rigid rubber end plate opposite to each other and spaced apart from each other. The flexible rubber end plate is attached to the rigid rubber end plate. One end of the two flexible rubber arc plates is disposed on the flexible rubber end plate opposite to each other and spaced apart from each other. The two flexible rubber arc plates are respectively attached to the inner sides of the two rigid rubber arc plates. A first through groove extending towards the central axis of the rigid rubber arc plate is opened on the opposite two sides of the rigid rubber arc plate. The first through groove penetrates the rigid rubber arc plate in the thickness direction. An accommodating space is formed between the two flexible rubber arc plates. Corresponding through holes are opened on the rigid rubber end plate and the flexible rubber end plate respectively. In practical applications, the end of the motor with the output shaft can be inserted into the receiving space, so that the two soft rubber arc plates cover the opposite sides of the motor respectively, and the output shaft of the motor passes through the receiving space through the two through holes. Under the pressure of the motor in the receiving space, the two soft rubber arc plates will move in opposite directions. At the same time, since each hard rubber arc plate has two first through slots, each hard rubber arc plate has a certain degree of elasticity. Therefore, the two hard rubber arc plates will move in opposite directions under the pressure of the two soft rubber arc plates. However, the outer sides of the two hard rubber arc plates abut against the inner sidewall of the housing, which restricts the movement of the two hard rubber arc plates in opposite directions. This restricts the movement of the two soft rubber arc plates in opposite directions, so that the motor, the two soft rubber arc plates, the two hard rubber arc plates and the inner sidewall of the housing are pressed against each other. In this way, the motor can be firmly clamped in the receiving space between the two soft rubber arc plates, and the vibration generated by the motor during operation will be canceled out by the elasticity of the two soft rubber arc plates and the two hard rubber arc plates. Therefore, the motor bracket of this application provides better fixation for the motor, making it less prone to loosening. It can effectively reduce the noise of the motor during operation and the vibration of the whole machine. At the same time, the motor bracket does not require the use of clips, screws and other parts, making assembly simpler and the cost lower.
[0015] The drive device provided in the second aspect of this application has all the advantages of the motor bracket provided in the first aspect of this application since it includes the motor bracket.
[0016] The electronic device provided in the third aspect of this application has all the advantages of the driving device provided in the second aspect of this application since it includes the driving device provided in the second aspect of this application. Attached Figure Description

Detailed Implementation
[0035] In related technologies, motors within electronic devices are typically secured by brackets. However, existing brackets are not ideal for securing motors, leading to easy loosening and exacerbating noise during motor operation and vibration of the entire device. Therefore, this application proposes a motor bracket, a drive device, and an electronic device in the embodiments below to address the aforementioned drawbacks in related technologies.
[0036] To make the objectives, technical solutions, and advantages of this application more apparent and understandable, this application will be clearly and completely described below in conjunction with its embodiments and corresponding drawings. Throughout, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. It should be understood that the embodiments of this application described below are only for explaining this application and are not intended to limit this application. That is, all other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0037] Please see Figures 1-7 , Figure 1 This is an exploded view of an electronic device. Figure 2 This is a structural diagram of the motor bracket. Figure 3This is an exploded view of the motor bracket from one perspective. Figure 4 This is a structural diagram of the rigid rubber part in the motor bracket. Figure 5 This is a structural diagram of the soft rubber part in the motor bracket. Figure 6 This is a schematic diagram of the assembly of the motor bracket and the motor. Figure 7 This is an exploded view of the motor bracket from another perspective. This embodiment provides a motor bracket 3, which is applied in an electronic device. The electronic device includes a housing 1 and a motor 2 disposed in the housing 1. The electronic device can be any electronic device equipped with a motor 2 in the art, such as a robot vacuum cleaner, an electric shaver, an electric toothbrush, a hair dryer, a drone, etc. The specific device can be selected according to actual needs, and this embodiment does not limit it to a single device.
[0038] Specifically, the motor bracket 3 is located inside the housing 1 and includes a rigid rubber end plate 31, a flexible rubber end plate 32, two rigid rubber arc-shaped plates 33, and two flexible rubber arc-shaped plates 34. One end of each of the two rigid rubber arc-shaped plates 33 is located on one side of the rigid rubber end plate 31. The two rigid rubber arc-shaped plates 33 are opposite to each other and spaced apart. The flexible rubber end plate 32 is attached to the side of the rigid rubber end plate 31 that connects with the two rigid rubber arc-shaped plates 33. One end of each of the two flexible rubber arc-shaped plates 34 is located on the flexible rubber end plate 32. The curved plates 34 are opposite to each other and spaced apart. The two soft rubber curved plates 34 are respectively attached to the inner sidewalls of the two hard rubber curved plates 33. The two opposite sides of the hard rubber curved plates 33 are respectively provided with a first through groove 331 extending towards the central axis of the hard rubber curved plates 33. The first through groove 331 penetrates the hard rubber curved plates 33 in the thickness direction. A receiving space 4 is formed between the two soft rubber curved plates 34. Corresponding through holes 35 are respectively provided on the hard rubber end plate 31 and the soft rubber end plate 32. It is understandable that the soft rubber end plate 32 and the soft rubber curved plate 34 are both made of soft rubber materials, such as silicone, thermoplastic elastomer, polyurethane, and natural rubber, while the hard rubber end plate 31 and the hard rubber curved plate 33 are both made of hard rubber materials, such as acrylonitrile-butadiene-styrene copolymer, polycarbonate, polyamide, polypropylene, and polyoxymethylene. Therefore, the elasticity of the soft rubber end plate 32 and the soft rubber curved plate 34 is better than that of the hard rubber end plate 31 and the hard rubber curved plate 33.
[0039] In this embodiment, the receiving space 4 between the two soft rubber arc plates 34 is used to receive the motor 2, specifically to receive one end of the motor 2 with an output shaft. When the end of the motor 2 with an output shaft is inserted into the receiving space 4, the two through holes 35 on the hard rubber end plate 31 and the soft rubber end plate 32 are used to allow the output shaft of the motor 2 to pass through the receiving space 4 to connect to the component driven by the motor 2. Taking an electric toothbrush as an example, the component driven by the motor 2 is the brush head 8 of the electric toothbrush. When the end of the motor 2 with an output shaft is inserted into the receiving space 4, the two soft rubber arc plates 34 are used to press between the two hard rubber arc plates 33 and the motor 2, respectively. The two hard rubber arc plates 33 are used to press between the two soft rubber arc plates 34 and the inner sidewall of the housing 1, thereby clamping the motor 2 in the receiving space 4.
[0040] In other words, in practical applications, the end of the motor 2 with the output shaft can be inserted into the receiving space 4, so that the two soft rubber arc plates 34 respectively cover the opposite sides of the motor 2, and the output shaft of the motor 2 passes through the two through holes 35 out of the receiving space 4. Due to the compression of the motor 2 in the receiving space 4, the two soft rubber arc plates 34 will move in opposite directions. At the same time, since each hard rubber arc plate 33 has two first through slots 331, each hard rubber arc plate 33 has a certain degree of elasticity, so the two hard rubber arc plates 33 will respectively be on the two soft rubber arc plates 34. Under the pressure, the two hard rubber arc plates 33 move in opposite directions, but the outer sides of both hard rubber arc plates 33 abut against the inner sidewall of the housing 1. This restricts the opposite movement of the two hard rubber arc plates 33, thereby restricting the opposite movement of the two soft rubber arc plates 34. This causes the motor 2, the two soft rubber arc plates 34, the two hard rubber arc plates 33 and the inner sidewall of the housing 1 to press against each other. In this way, the motor 2 can be firmly clamped in the receiving space 4 between the two soft rubber arc plates 34, and the vibration generated by the motor 2 during operation will be offset by the elasticity of the two soft rubber arc plates 34 and the two hard rubber arc plates 33.
[0041] As can be seen from the above, the motor bracket 3 in this embodiment has a better fixing effect on the motor 2, and the motor 2 is not easy to loosen. It can effectively reduce the noise of the motor 2 during operation and the vibration of the whole machine. At the same time, the motor bracket 3 does not require the use of clips, screws and other parts, making the assembly simpler and the cost lower.
[0042] In some embodiments, please refer to Figures 1-7The two first through grooves 331 on the same rigid rubber arc plate 33 are opposite to each other and spaced apart, preferably symmetrical with respect to the central axis of the same rigid rubber arc plate 33. Specifically, the first through groove 331 can extend in a straight line or bend, and can be designed according to actual needs. This application does not limit it in this way. Preferably, the first through groove 331 extends in a bend, and the bending direction of the first through groove 331 is towards the rigid rubber end plate 31. Furthermore, the distance between the position of the first through groove 331 on the side of the rigid curved plate 33 and the end of the rigid curved plate 33 away from the rigid end plate 31 is defined as the first distance, and the distance between the position of the first through groove 331 on the side of the rigid curved plate 33 and the other end of the rigid curved plate 33 is defined as the second distance. Then the first distance is less than the second distance. In this way, the two first through grooves 331 on the rigid curved plate 33 can divide the rigid curved plate 33 into a rear end that is connected to the rigid end plate 31 and a front end that is away from the rigid end plate 31. At the same time, since the first distance is less than the second distance, the front end of the rigid curved plate 33 is smaller than the rear end. This setting can maximize the elasticity of the rigid curved plate 33 and ensure that it covers the area of the motor 2, thereby further increasing the fixing effect of the motor bracket 3 on the motor 2, that is, further improving the reduction effect of motor 2 operating noise and overall machine vibration.
[0043] Correspondingly, the two opposite sides of the soft rubber curved plate 34 are respectively provided with second through slots (not shown in the figure) extending towards the central axis of the soft rubber curved plate 34 and penetrating through the soft rubber curved plate 34 in the thickness direction. In the soft rubber curved plate 34 and the hard rubber curved plate 33 that are in contact with each other, the second through slots on the same side are aligned with the first through slots 331 and have the same structure. It can be understood that this arrangement can maximize the elasticity of the soft rubber curved plate 34 and ensure that it covers the area of the motor 2. At the same time, combined with the two first through slots 331 on the hard rubber curved plate 33, the fixing effect of the motor bracket 3 on the motor 2 can be optimized, thereby optimizing the reduction effect of motor 2 operating noise and overall machine vibration.
[0044] In some embodiments, please refer to Figures 1-7The inner wall of the rigid curved plate 33 has a positioning groove 332 extending along the length direction, and the outer side of the soft curved plate 34 has a positioning rib 341 extending along the length direction. In the mating soft curved plate 34 and rigid curved plate 33, the positioning rib 341 is inserted into the positioning groove 332 and is pressed against the groove wall of the positioning groove 332. Furthermore, the inner side of each soft curved plate 34 has a limiting rib 342 extending along the length direction, and the outer wall of the motor 2 has two limiting grooves (not shown) extending along the length direction and symmetrical with respect to the central axis of the motor 2. When the end of the motor 2 with the output shaft is inserted into the receiving space 4, the two limiting ribs 342 are respectively inserted into the two limiting grooves and are pressed against the groove walls of the two limiting grooves. Furthermore, each rigid rubber arc plate 33 has a guide rib 333 extending along its length on its outer side. The inner wall of the housing 1 has two guide grooves (not shown) extending along its length and symmetrical with respect to the central axis of the housing 1. The two guide ribs 333 are inserted into the two guide grooves and are pressed against the groove walls. It can be understood that through the insertion and pressing of the positioning groove 332 with the positioning rib 341, the insertion and pressing of the limiting rib 342 with the limiting groove, and the insertion and pressing of the guide rib 333 with the guide groove, the assembly stability between the motor 2, the two soft rubber arc plates 34, the two rigid rubber arc plates 33, and the housing 1 can be strengthened, thereby improving the fixing effect of the motor bracket 3 on the motor 2, and thus reducing the noise of the motor 2 during operation and the vibration of the whole machine, ensuring the user's experience of using the electronic device.
[0045] In some embodiments, please refer to Figures 1-7 and combined Figure 10 , Figure 10 This is a schematic diagram of the motor structure. At least one first fixing hole 37 is provided on both the rigid rubber end plate 31 and the flexible rubber end plate 32, and at least one second fixing hole 21 is provided on the end face of the motor 2 with the output shaft. The at least one second fixing hole 21 is used to align with the at least one first fixing hole 37 when the motor 2 is located in the receiving space 4. Based on this, in addition to the structure described above, the motor bracket 3 also includes at least one fastener 36. The at least one fastener 36 is used to be inserted into the at least one first fixing hole 37 and the at least one second fixing hole 21 when the motor 2 is located in the receiving space 4, thereby further fixing the motor 2 in the receiving space 4. Furthermore, it should be noted that the number of first fixing holes 37 on the rigid rubber end plate 31, the number of first fixing holes 37 on the flexible rubber end plate 32, the number of second fixing holes 21 on the motor 2, and the number of fasteners 36 are all equal. Their numbers can be designed according to actual needs, and this application does not impose a unique limitation on them; exemplarily, the number of each is two. Preferably, the first fixing hole 37 and the second fixing hole 21 are both screw holes, and the fastener 36 is a bolt.
[0046] Please see Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the drive unit. Figure 9 This is an exploded view of the drive device. This embodiment provides a drive device housed in the casing 1 of an electronic device. The drive device includes a motor 2, a power supply 5, a power supply bracket 6, and the motor bracket 3 described above. One end of the motor 2, having an output shaft, is inserted into a receiving space 4 between two soft rubber arc-shaped plates 34. The output shaft of the motor 2 passes through two through holes 35 on the hard rubber end plate 31 and the soft rubber end plate 32, exiting the receiving space 4 to connect to a component driven by the motor 2 (taking an electric toothbrush as an example, the component driven by the motor 2 is the brush head 8; the motor 2 can drive...). The moving brush head 8 vibrates, thus realizing the automatic brushing function of the electric toothbrush. A recessed insertion hole 61 is provided on one end face of the power supply bracket 6. The end of the motor 2 opposite to the output shaft is inserted into the insertion hole 61. A recessed placement groove 62 is provided on the outer wall of the power supply bracket 6, adjacent to the other end of the power supply bracket 6 (i.e., the end away from the motor 2). The power supply 5 is placed in the placement groove 62 and electrically connected to the motor 2 to provide the power required for the motor 2 to operate. The motor 2, the power supply bracket 6, and the inner wall of the housing 1 are pressed against each other. It can be understood that the fixation of the motor 2 within the housing 1 depends not only on the motor bracket 3 described above, but also on the power supply bracket 6 in the drive device. The mutual pressing between the motor 2, the power supply bracket 6, and the inner wall of the housing 1 further fixes the motor 2. In other words, this embodiment adopts a dual fixing method, that is, the motor bracket 3 and the power supply bracket 6 fix the opposite ends of the motor 2 respectively, resulting in a better fixing effect.
[0047] In some embodiments, still refer to Figure 9 In addition to the structure described above, the drive unit also includes a shock-absorbing sleeve 7. The shock-absorbing sleeve 7 is disposed in the socket 61 of the power supply bracket 6, and fits snugly against the wall of the socket 61. The end of the motor 2 opposite to the output shaft is inserted into the shock-absorbing sleeve 7. In this case, the motor 2, the shock-absorbing sleeve 7, the power supply bracket 6, and the inner wall of the housing 1 are pressed against each other. It is understood that the shock-absorbing sleeve 7 is generally made of a material with good elasticity. Adding a shock-absorbing sleeve 7 in the socket 61 of the power supply bracket 6 can improve the fixing effect of the power supply bracket 6 on the end of the motor 2 away from the output shaft, and further reduce the noise and overall vibration of the motor 2.
[0048] In some embodiments, please refer to Figure 10 and combined Figure 11 and Figure 12 , Figure 11 This is a structural diagram of the shock-absorbing sleeve. Figure 12This is a schematic diagram of the power supply bracket. The outer wall of the motor 2 has two first fixing ribs 22 extending along the length direction and adjacent to the end opposite to the output shaft. The two first fixing ribs 22 are symmetrical with respect to the central axis of the motor 2. The inner wall of the shock-absorbing sleeve 7 has two first fixing grooves 71 extending along the length direction and symmetrical with respect to the central axis of the shock-absorbing sleeve 7. The two first fixing ribs 22 are respectively inserted into the two first fixing grooves 71 and are pressed against the groove walls of the two first fixing grooves 71. Further, the outer wall of the shock-absorbing sleeve 7 has two second fixing ribs 72 extending along the length direction and symmetrical with respect to the central axis of the shock-absorbing sleeve 7. The wall of the insertion hole 61 has two second fixing grooves 611 extending along the length direction and symmetrical with respect to the hole axis of the insertion hole 61. The two second fixing ribs 72 are respectively inserted into the two second fixing grooves 611 and are pressed against the groove walls of the two second fixing grooves 611. Furthermore, two third fixing ribs 63 extending along the length direction and symmetrical with respect to the central axis of the power supply bracket 6 are formed on the outer side wall of the power supply bracket 6. Two third fixing grooves (not shown) extending along the length direction and symmetrical with respect to the central axis of the housing 1 are formed on the inner side wall of the housing 1. The two third fixing ribs 63 are respectively inserted into the two third fixing grooves and are respectively pressed against the groove walls of the two third fixing grooves. It can be understood that through the insertion and pressing of the first fixing rib 22 with the first fixing groove 71, the insertion and pressing of the second fixing rib 72 with the second fixing groove 611, and the insertion and pressing of the third fixing rib 63 with the third fixing groove, the assembly stability between the motor 2, the shockproof sleeve 7, the power supply bracket 6, and the inner side wall of the housing 1 can be strengthened, thereby improving the fixing effect of the power supply bracket 6 on the motor 2, and thus reducing the noise of the motor 2 during operation and the vibration of the whole machine.
[0049] Furthermore, it should be noted that the third fixing rib 63 in this application can be a single piece or divided into blocks, as can the second fixing rib 72 and the first fixing rib 22. The specific design can be tailored to actual needs, and this application does not impose a unique limitation on this. For example, the third fixing rib 63 is divided into blocks, meaning that the third fixing rib 63 includes multiple fixing blocks 631 spaced apart from each other along the length of the power supply bracket 6. Of course, taking the third fixing rib 63 and the third fixing groove as examples, if the third fixing rib 63 is divided into blocks, then the third fixing groove can be either a single piece or divided into blocks, and the specific design can be tailored to actual needs. This application does not impose a unique limitation on this.
[0050] Please see Figure 13 and Figure 14 , Figure 13 This is a structural diagram of an electric toothbrush. Figure 14This is a first exploded view of an electric toothbrush. This embodiment provides an electronic device, taking an electric toothbrush as an example. The electric toothbrush includes a housing 1, a brush head 8, and the driving device described above. The driving device is located inside the housing 1. The output shaft of the motor 2 in the driving device extends out of the housing 1 and is connected to the brush head 8, so that the motor 2 drives the brush head 8 to vibrate, thereby realizing the automatic brushing function of the electric toothbrush. Preferably, the output shaft of the motor 2 can be connected to the brush head 8 through a transmission device (not shown), thereby improving transmission efficiency and achieving efficient brushing and vibration functions of the electric toothbrush. Furthermore, it should be noted that the transmission device can adopt any transmission structure commonly used in the art that can improve transmission efficiency, such as gears, belts, or magnetic coupling, etc., and can be selected according to actual needs. This embodiment does not impose a unique limitation on this.
[0051] In some embodiments, please refer to Figure 14 The housing 1 includes an inner housing 11 and an outer housing 12 fitted onto the outer wall of the inner housing 11. The outer housing 12 is transparent, and a coating (not shown) is formed on the outer surface of the inner housing 11. The coating includes at least one color. It is understood that since the outer housing 12 is transparent, the user can see the outer surface of the inner housing 11 through the outer housing 12. The outer surface of the inner housing 11 can be coated with colorful coatings, thus providing the user with a rich visual experience and improving the appearance of the electric toothbrush. Furthermore, it should be noted that the outer housing 12 is made of transparent materials, such as glass, polymethyl methacrylate, polycarbonate, polystyrene, polyethylene terephthalate, and hydrogel, etc., and the specific choice can be made according to actual needs; this application does not impose a unique limitation on this.
[0052] In some embodiments, please refer to Figure 15 , Figure 15 This is a second exploded view of an electric toothbrush. In addition to the structure given above, the electric toothbrush also includes other common components found in electric toothbrushes in the art, such as the motherboard 9, sensing copper foil 10, diffuser 20, button 30, light shield 40, housing cover 50, USB cover 60, and USB female connector 70. Since the application of these components in electric toothbrushes is a relatively mature technology, this application will not describe them in detail.
[0053] The above embodiments are merely preferred implementations of this application and are not the only limitations on the motor bracket 3, the drive device, and related electronic equipment. Those skilled in the art can make flexible settings based on the above embodiments and according to the actual application scenario. It is understood that, through the implementation of the above embodiments of this application, the motor bracket 3 is constituted by the hard plastic end plate 31, the soft plastic end plate 32, the two hard plastic arc plates 33, and the two soft plastic arc plates 34. One end of the two hard plastic arc plates 33 is disposed on the hard plastic end plate 31 with respect to each other and spaced apart. The soft plastic end plate 32 is attached to the hard plastic end plate 31. One end of the two soft plastic arc plates 34 is disposed on the soft plastic end plate 32 with respect to each other and spaced apart. The two soft plastic arc plates 34 are respectively attached to the inner side of the two hard plastic arc plates 33. The two opposite sides of the hard plastic arc plates 33 are respectively provided with a first through groove 331 extending towards the central axis of the hard plastic arc plates 33. The first through groove 331 penetrates the hard plastic arc plates 33 in the thickness direction. A receiving space 4 is formed between the two soft plastic arc plates 34. Corresponding through holes 35 are respectively provided on the hard plastic end plate 31 and the soft plastic end plate 32. In practical applications, the end of the motor 2 with the output shaft can be inserted into the receiving space 4, so that the two soft rubber arc plates 34 cover the opposite sides of the motor 2 respectively, and the output shaft of the motor 2 passes through the two through holes 35 out of the receiving space 4. Due to the compression of the motor 2 in the receiving space 4, the two soft rubber arc plates 34 will move in opposite directions. At the same time, since each hard rubber arc plate 33 has two first through slots 331, each hard rubber arc plate 33 has a certain degree of elasticity. Therefore, the two hard rubber arc plates 33 will move in opposite directions under the compression of the two soft rubber arc plates 34 respectively. While the two hard rubber arc plates 33 move backwards, their outer sides abut against the inner wall of the housing 1, thus restricting their backward movement. This, in turn, restricts the backward movement of the two soft rubber arc plates 34, causing the motor 2, the two soft rubber arc plates 34, the two hard rubber arc plates 33, and the inner wall of the housing 1 to press against each other. This securely clamps the motor 2 within the receiving space 4 between the two soft rubber arc plates 34, and most of the vibration generated by the motor 2 during operation is offset by the elasticity of the two soft rubber arc plates 34 and the two hard rubber arc plates 33. Therefore, the motor bracket 3 of this application provides better fixation for the motor 2, making it less prone to loosening. It effectively reduces noise and overall vibration during motor operation. Furthermore, the motor bracket 3 eliminates the need for clips, screws, or other components, simplifying assembly and reducing costs.
