[0001] The present application relates to the technical field of motors, in particular to a motor support, a driving device and an electronic device. BACKGROUND

[0002] A motor (a common name of an electric machine) can convert electrical energy into mechanical energy according to the law of electromagnetic induction, and is an indispensable power source in electronic devices. For example, a sweeping robot, an electric shaver, an electric toothbrush, a hair dryer, a drone and other electronic devices all need to use a motor to provide power. In the related art, the motor in the electronic device needs to be fixed by a support, but the existing support has an unsatisfactory fixing effect on the motor, and the motor is prone to looseness, thereby increasing the noise during operation of the motor and the vibration of the whole machine. SUMMARY

[0003] The present application provides a motor support, a driving device and an electronic device, aiming to solve the problem of large noise during operation of the motor and aggravation of the vibration of the whole machine in the related art.

[0004] In order to solve the above-mentioned problems existing in the related art, the first aspect of the present application provides a motor support, which is applied to an electronic device, the electronic device comprising a casing and a motor arranged in the casing, the motor support being arranged in the casing and comprising a hard rubber end plate, a soft rubber end plate, two hard rubber arc-shaped plates and two soft rubber arc-shaped plates, one end of each of the two hard rubber arc-shaped plates being oppositely and mutually spacedly arranged on the hard rubber end plate, the soft rubber end plate being attached to the hard rubber end plate, one end of each of the two soft rubber arc-shaped plates being oppositely and mutually spacedly arranged on the soft rubber end plate, each of the two soft rubber arc-shaped plates being attached to the inner side of each of the two hard rubber arc-shaped plates, each of the hard rubber arc-shaped plates being provided with a first through groove extending towards the central axis of the hard rubber arc-shaped plate on opposite sides of the hard rubber arc-shaped plate, the first through groove penetrating the hard rubber arc-shaped plate in the thickness direction, a containing space being formed between the two soft rubber arc-shaped plates, and corresponding through holes being provided in the hard rubber end plate and the soft rubber end plate. Specifically, the containing space is used for containing the motor; the two through holes are used for allowing the output shaft of the motor to pass out of the containing space; and the two soft rubber arc-shaped plates are used for being pressed between the two hard rubber arc-shaped plates and the motor respectively, and the two hard rubber arc-shaped plates are used for being pressed between the two soft rubber arc-shaped plates and the inner side wall of the casing respectively, so as to clamp the motor in the containing space.

[0005] In some implementation schemes, the two first through grooves on the same hard rubber arc-shaped plate are oppositely and mutually spaced, and each of the first through grooves extends in a curved manner, and the curved direction of each of the first through grooves is towards the hard rubber end plate.

[0007] In some implementations, the soft arc-shaped plate has a second through groove formed on each of the opposite sides and extending towards the central axis of the soft arc-shaped plate and penetrating the soft arc-shaped plate in the thickness direction; in the abutted soft arc-shaped plate and hard arc-shaped plate, the second through groove on the same side is aligned with the first through groove and has the same structure.

[0008] In some implementations, the inner side wall of the hard arc-shaped plate has a positioning groove extending in the length direction, and the outer side of the soft arc-shaped plate has a positioning rib extending in the length direction; in the abutted soft arc-shaped plate and hard arc-shaped plate, the positioning rib is inserted into the positioning groove and is pressed against the groove wall of the positioning groove.

[0009] In some implementations, the inner side of each soft arc-shaped plate has a limiting rib extending in the length direction, and the outer side wall of the motor has two limiting grooves extending in the length direction and symmetrical with respect to the central axis of the motor, and the two limiting ribs are respectively inserted into the two limiting grooves and are pressed against the groove walls of the two limiting grooves.

[0010] In some implementations, the outer side of each hard arc-shaped plate has a guide rib extending in the length direction, and the inner side wall of the casing has two guide grooves extending in the length direction and symmetrical with respect to the central axis of the casing, and the two guide ribs are respectively inserted into the two guide grooves and are pressed against the groove walls of the two guide grooves.

[0011] In some implementations, the hard end plate and the soft end plate have at least one first fixing hole aligned thereon, and the end face of the one end of the output shaft of the motor has at least one second fixing hole, and the at least one second fixing hole is aligned with the at least one first fixing hole when the motor is located in the accommodation space. Based on this, the motor support includes at least one fastener in addition to the structure given in the foregoing, and the at least one fastener is inserted into the at least one first fixing hole and the at least one second fixing hole when the motor is located in the accommodation space, so as to fix the motor in the accommodation space.

[0012] The second aspect of the present application provides a driving device applied in an electronic device, the electronic device comprising a casing, the driving device being arranged in the casing and comprising a motor, a power supply, a power supply support and the motor support provided in the first aspect of the present application. The one end of the output shaft of the motor is inserted into the accommodation space, the output shaft of the motor passes through the two through holes and out of the accommodation space, the end face of one end of the power supply support has an inwardly recessed insertion hole, the end opposite to the output shaft of the motor is inserted into the insertion hole, the outer side wall of the power supply support has an inwardly recessed placement groove adjacent to the other end of the power supply support, the power supply is arranged in the placement groove and is electrically connected to the motor, and the motor, the power supply support and the inner side wall of the casing are pressed against each other.

[0013] The third aspect of the present application provides an electronic device, which comprises a casing and the driving device provided by the second aspect of the present application, and the driving device is arranged in the casing.

[0014] For the motor support provided by the first aspect of the present application, it is applied to an electronic device, which comprises a casing, and the casing is internally provided with a motor and the motor support. The motor support is composed of a hard rubber end plate, a soft rubber end plate, two hard rubber arc-shaped plates and two soft rubber arc-shaped plates. The two hard rubber arc-shaped plates are oppositely and mutually spacedly arranged on the hard rubber end plate. The soft rubber end plate is attached to the hard rubber end plate. The two soft rubber arc-shaped plates are oppositely and mutually spacedly arranged on the soft rubber end plate. The two soft rubber arc-shaped plates are respectively attached to the inner sides of the two hard rubber arc-shaped plates. The two opposite side edges of the hard rubber arc-shaped plate are respectively provided with a first through slot extending to the central axis of the hard rubber arc-shaped plate. The first through slot penetrates the hard rubber arc-shaped plate in the thickness direction. The accommodating space is formed between the two soft rubber arc-shaped plates. Corresponding through holes are respectively arranged on the hard rubber end plate and the soft rubber end plate. In actual application, the one end of the motor provided with an output shaft can be inserted into the accommodating space, so that the two soft rubber arc-shaped plates respectively cover the two opposite sides of the motor, and the output shaft of the motor passes through the two through holes and protrudes out of the accommodating space. The two soft rubber arc-shaped plates are moved away from each other under the extrusion of the motor in the accommodating space. Since two first through slots are arranged on each hard rubber arc-shaped plate, each hard rubber arc-shaped plate has a certain elasticity, so the two hard rubber arc-shaped plates are moved away from each other under the extrusion of the two soft rubber arc-shaped plates. However, the outer sides of the two hard rubber arc-shaped plates abut against the inner side wall of the casing, which limits the movement of the two hard rubber arc-shaped plates away from each other, thereby limiting the movement of the two soft rubber arc-shaped plates away from each other. The mutual extrusion between the motor, the two soft rubber arc-shaped plates, the two hard rubber arc-shaped plates and the inner side wall of the casing is achieved, so that the motor can be firmly clamped in the accommodating space between the two soft rubber arc-shaped plates, and the vibration generated by the motor during operation can be offset by the elasticity of the two soft rubber arc-shaped plates and the two hard rubber arc-shaped plates. As can be seen, the motor support of the present application has better fixing effect on the motor, the motor is not easy to loosen, and the noise during operation of the motor and the vibration of the whole machine can be effectively reduced. Meanwhile, the motor support does not need to use buckles, screws and other components, and the assembly is simpler and the cost is lower.

[0015] For the driving device provided by the second aspect of the present application, since it comprises the motor support provided by the first aspect of the present application, it has all the advantages of the motor support.

[0016] For the electronic device provided by the third aspect of the present application, since it comprises the driving device provided by the second aspect of the present application, it has all the advantages of the driving device. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0035] In the prior art, motors within electronic devices are typically secured by brackets. However, existing brackets are not ideal for securing motors, and motors can easily become loose, exacerbating noise and vibration during operation. In light of this, the present application proposes a motor bracket, drive device, and electronic device in the following embodiments to address the aforementioned drawbacks of the prior art.

[0036] In order to make the purpose, technical solutions and advantages of the present application more obvious and easy to understand, the present application will be clearly and completely described below in conjunction with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. It should be understood that the embodiments of the present application described below are only used to explain the present application and are not used to limit the present application, that is, based on the various embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0037] See also Figures 1-7 , Figure 1 This is an exploded diagram of an electronic device. Figure 2 This is a schematic diagram of the motor bracket structure. Figure 3is an exploded view of the motor support from one perspective, Figure 4 is a structural view of a hard glue part in the motor support, Figure 5 is a structural view of a soft glue part in the motor support, Figure 6 is an assembly view of the motor support and the motor, Figure 7 is an exploded view of the motor support from another perspective. The embodiment provides a motor support 3 applied to an electronic device, the electronic device comprising a casing 1 and a motor 2 arranged in the casing 1, and the electronic device can be any electronic device provided with the motor 2 in the art, such as a sweeping robot, an electric shaver, an electric toothbrush, a hair dryer, a drone, etc., which can be specifically selected according to actual needs, and the embodiment does not make a unique limitation thereto.

[0038] Specifically, the motor support 3 is arranged in the casing 1 and comprises a hard glue end plate 31, a soft glue end plate 32, two hard glue arc-shaped plates 33, and two soft glue arc-shaped plates 34. One end of each of the two hard glue arc-shaped plates 33 is arranged on one side of the hard glue end plate 31, and the two hard glue arc-shaped plates 33 are opposite and spaced from each other. The soft glue end plate 32 is attached to the side of the hard glue end plate 31 where the two hard glue arc-shaped plates 33 are connected. One end of each of the two soft glue arc-shaped plates 34 is arranged on the soft glue end plate 32, and the two soft glue arc-shaped plates 34 are opposite and spaced from each other. The two soft glue arc-shaped plates 34 are respectively attached to the inner side walls of the two hard glue arc-shaped plates 33. The opposite side edges of the hard glue arc-shaped plate 33 are respectively provided with a first through slot 331 extending to the central axis of the hard glue arc-shaped plate 33. The first through slot 331 penetrates the hard glue arc-shaped plate 33 in the thickness direction. The accommodating space 4 is formed between the two soft glue arc-shaped plates 34. Corresponding through holes 35 are respectively arranged in the hard glue end plate 31 and the soft glue end plate 32. It can be understood that the soft glue end plate 32 and the soft glue arc-shaped plate 34 are made of soft glue material, such as silicone, thermoplastic elastomer, polyurethane, natural rubber, etc., and the hard glue end plate 31 and the hard glue arc-shaped plate 33 are made of hard glue material, such as acrylonitrile-butadiene-styrene copolymer, polycarbonate, polyamide, polypropylene, polyformaldehyde, etc. Therefore, the elasticity of the soft glue end plate 32 and the soft glue arc-shaped plate 34 is better than that of the hard glue end plate 31 and the hard glue arc-shaped plate 33.

[0039] In the embodiment, the accommodating space 4 between the two soft arc-shaped plates 34 is used to accommodate the motor 2, and in particular, is used to accommodate one end of the motor 2 provided with an output shaft; when the one end of the motor 2 provided with the output shaft is inserted into the accommodating 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 out of the accommodating space 4, so as to connect the component driven by the motor 2, for example, the brush head 8 of the electric toothbrush; when the one end of the motor 2 provided with the output shaft is inserted into the accommodating space 4, the two soft arc-shaped plates 34 are used to be pressed between the two hard arc-shaped plates 33 and the motor 2 respectively, and the two hard arc-shaped plates 33 are used to be pressed between the two soft arc-shaped plates 34 and the inner side wall of the casing 1 respectively, so as to clamp the motor 2 in the accommodating space 4.

[0040] That is to say, in actual application, the one end of the motor 2 provided with the output shaft can be inserted into the accommodating space 4, so that the two soft arc-shaped plates 34 wrap the opposite sides of the motor 2 respectively, and the output shaft of the motor 2 passes out of the accommodating space 4 through the two through holes 35; under the extrusion of the motor 2 in the accommodating space 4, the two soft arc-shaped plates 34 move away from each other, and at the same time, since two first through grooves 331 are formed on each hard arc-shaped plate 33, which makes each hard arc-shaped plate 33 have a certain elasticity, so the two hard arc-shaped plates 33 move away from each other under the extrusion of the two soft arc-shaped plates 34, but the outer sides of the two hard arc-shaped plates 33 abut against the inner side wall of the casing 1, which limits the movement of the two hard arc-shaped plates 33 away from each other, and thus limits the movement of the two soft arc-shaped plates 34 away from each other, so that the motor 2, the two soft arc-shaped plates 34, the two hard arc-shaped plates 33 and the inner side wall of the casing 1 extrude each other, so that the motor 2 can be clamped firmly in the accommodating space 4 between the two soft arc-shaped plates 34, and the vibration generated by the motor 2 during operation can be offset by the elasticity of the two soft arc-shaped plates 34 and the two hard arc-shaped plates 33.

[0041] As can be seen from the above, the motor support 3 of the embodiment has a better fixing effect on the motor 2, and the motor 2 is not easy to loosen, which can effectively reduce the noise during operation of the motor 2 and the vibration of the whole machine, and at the same time, the motor support 3 does not need to use buckles, screws and other components, so the assembly is simpler and the cost is lower.

[0042] In some embodiments, please refer to Figures 1-7The two first through-slots 331 on the same hard-rubber arc-shaped plate 33 are opposite and spaced apart from each other, preferably symmetric to the central axis of the same hard-rubber arc-shaped plate 33. Specifically, the first through-slots 331 can extend linearly or curvedly, which can be designed according to actual needs, and the present application does not make a unique limitation thereon; preferably, the first through-slots 331 extend curvedly, and the curved direction of the first through-slots 331 is towards the hard-rubber end plate 31. Further, the distance between the position where the first through-slots 331 are arranged on the side edge of the hard-rubber arc-shaped plate 33 and the end of the hard-rubber arc-shaped plate 33 away from the hard-rubber end plate 31 is defined as a first distance, and the distance between the position where the first through-slots 331 are arranged on the side edge of the hard-rubber arc-shaped plate 33 and the other end of the hard-rubber arc-shaped plate 33 is defined as a second distance, then the first distance is less than the second distance; in this way, the two first through-slots 331 on the hard-rubber arc-shaped plate 33 can divide the hard-rubber arc-shaped plate 33 into a rear end connected with the hard-rubber end plate 31 and a front end away from the hard-rubber end plate 31, and since the first distance is less than the second distance, the front end of the hard-rubber arc-shaped plate 33 is smaller than the rear end, which can increase the elasticity of the hard-rubber arc-shaped plate 33 to the maximum extent and ensure the area of the hard-rubber arc-shaped plate 33 covering the motor 2, thereby further increasing the fixing effect of the motor support 3 on the motor 2, i.e., further improving the weakening effect of the motor 2 running noise and the whole machine vibration.

[0043] Correspondingly, the two opposite side edges of the soft-rubber arc-shaped plate 34 are respectively arranged with a second through-slot (not shown in the figure) extending towards the central axis of the soft-rubber arc-shaped plate 34 and penetrating the soft-rubber arc-shaped plate 34 in the thickness direction, and the second through-slots and the first through-slots 331 on the same side of the abutting soft-rubber arc-shaped plate 34 and the hard-rubber arc-shaped plate 33 are aligned and have the same structure. It can be understood that such arrangement can increase the elasticity of the soft-rubber arc-shaped plate 34 to the maximum extent and ensure the area of the soft-rubber arc-shaped plate 34 covering the motor 2, and in combination with the two first through-slots 331 on the hard-rubber arc-shaped plate 33, the fixing effect of the motor support 3 on the motor 2 can be optimized, thereby optimizing the weakening effect of the motor 2 running noise and the whole machine vibration.

[0044] In some embodiments, referring to Figures 1-7The inner side wall of the hard arc-shaped plate 33 is provided with a positioning groove 332 extending along the length direction, and the outer side of the soft arc-shaped plate 34 is formed with a positioning rib 341 extending along the length direction. In the soft arc-shaped plate 34 and the hard arc-shaped plate 33 which are attached to each other, the positioning rib 341 is inserted into the positioning groove 332 and is pressed against the groove wall of the positioning groove 332. Further, the inner side of each soft arc-shaped plate 34 is formed with a limiting rib 342 extending along the length direction, and the outer side wall of the motor 2 is provided with two limiting grooves (not shown in the figure) extending along the length direction and symmetrical with respect to the central axis of the motor 2. When one end of the output shaft of the motor 2 is inserted into the accommodating space 4, the two limiting ribs 342 are respectively inserted into the two limiting grooves and are respectively pressed against the groove walls of the two limiting grooves. Further, the outer side of each hard arc-shaped plate 33 is formed with a guide rib 333 extending along the length direction, and the inner side wall of the casing 1 is provided with two guide grooves (not shown in the figure) extending along the length direction and symmetrical with respect to the central axis of the casing 1. The two guide ribs 333 are respectively inserted into the two guide grooves and are respectively pressed against the groove walls of the two guide grooves. It can be understood that, through the insertion and pressing of the positioning groove 332 and the positioning rib 341, the insertion and pressing of the limiting rib 342 and the limiting groove, and the insertion and pressing of the guide rib 333 and the guide groove, the assembly stability between the motor 2, the two soft arc-shaped plates 34, the two hard arc-shaped plates 33 and the casing 1 can be strengthened, so as to improve the fixing effect of the motor support 3 on the motor 2, and further weaken the noise of the motor 2 during operation and the vibration of the whole machine, thereby ensuring the user experience of the electronic equipment.

[0045] In some embodiments, referring to Figures 1-7 and combining Figure 10 , Figure 10 is a structural schematic diagram of a motor. The hard end plate 31 and the soft end plate 32 are respectively provided with at least one first fixing hole 37 aligned, and the end face of one end of the output shaft of the motor 2 is provided with at least one second fixing hole 21. The at least one second fixing hole 21 is used to align with the at least one first fixing hole 37 one by one when the motor 2 is located in the accommodating space 4. Based on this, in addition to the structure given in the foregoing, the motor support 3 further includes at least one fastener 36. The at least one fastener 36 is used to be correspondingly 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 accommodating space 4, so as to further fix the motor 2 in the accommodating space 4. In addition, it needs to be noted that the number of the first fixing holes 37 on the hard end plate 31, the number of the first fixing holes 37 on the soft end plate 32, the number of the second fixing holes 21 on the motor 2 and the number of the fasteners 36 are equal, and their number can be designed according to actual needs, which is not uniquely limited in the present application. Exemplarily, the number of them 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] Referring to Figure 8 andFigure 9 , Figure 8 is a structural diagram of the driving device, Figure 9 is an exploded diagram of the driving device. The embodiment provides a driving device arranged in a shell 1 of an electronic device, which comprises a motor 2, a power supply 5, a power supply support 6 and the motor support 3 described above. The motor 2 is arranged with one end of an output shaft inserted into a containing 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 to exit the containing space 4, so as to be connected to a component driven by the motor 2 (for example, the electric toothbrush, the component driven by the motor 2 is a brush head 8, and the motor 2 can drive the brush head 8 to vibrate when in operation, so as to realize the automatic tooth brushing function of the electric toothbrush). An end face of one end of the power supply support 6 is provided with an inwardly recessed insertion hole 61, and the motor 2 is inserted into the insertion hole 61 at the opposite end of the output shaft. An outer side wall of the power supply support 6 is provided with an inwardly recessed placement groove 62 adjacent to the other end of the power supply support 6 (i.e., the end away from the motor 2). The power supply 5 is arranged in the placement groove 62 and electrically connected to the motor 2, so as to provide the motor 2 with electric energy required for operation. The motor 2, the power supply support 6 and the inner side wall of the shell 1 are mutually extruded. It can be understood that the fixation of the motor 2 in the shell 1 not only depends on the motor support 3 described above, but also depends on the power supply support 6 in the driving device. The mutual extrusion between the motor 2, the power supply support 6 and the inner side wall of the shell 1 can achieve further fixation of the motor 2. That is to say, the embodiment adopts a double fixation mode, i.e., the motor support 3 and the power supply support 6 respectively fix the opposite ends of the motor 2, and the fixation effect is better.

[0047] In some embodiments, still referring to Figure 9 , the driving device comprises a shockproof sleeve 7 in addition to the structure given above. The shockproof sleeve 7 is arranged in the insertion hole 61 of the power supply support 6, and the shockproof sleeve 7 is in close contact with the hole wall of the insertion hole 61. The motor 2 is inserted into the shockproof sleeve 7 at the opposite end of the output shaft. In this case, the motor 2, the shockproof sleeve 7, the power supply support 6 and the inner side wall of the shell 1 are mutually extruded. It can be understood that the shockproof sleeve 7 is generally made of a material with good elasticity. The addition of the shockproof sleeve 7 in the insertion hole 61 of the power supply support 6 can improve the fixation effect of the power supply support 6 on the end of the motor 2 away from the output shaft, and further weaken the noise and the whole machine vibration when the motor 2 vibrates.

[0048] In some embodiments, please refer to Figure 10 , and combine Figure 11 and Figure 12 , Figure 11 is a structural diagram of the shockproof sleeve, Figure 12is a structural schematic view of the power support. The outer side wall of the motor 2 is formed with two first fixing ribs 22 extending along the length direction and adjacent to the end opposite to the output shaft, and the two first fixing ribs 22 are symmetrical with respect to the central axis of the motor 2. The inner side wall of the shockproof sleeve 7 is formed with two first fixing grooves 71 extending along the length direction and symmetrical with respect to the central axis of the shockproof sleeve 7, and the two first fixing ribs 22 are respectively inserted into the two first fixing grooves 71 and respectively extruded with the groove walls of the two first fixing grooves 71. Further, the outer side wall of the shockproof sleeve 7 is formed with two second fixing ribs 72 extending along the length direction and symmetrical with respect to the central axis of the shockproof sleeve 7, and the hole wall of the insertion hole 61 is formed with two second fixing grooves 611 extending along the length direction and symmetrical with respect to the hole axis of the insertion hole 61, and the two second fixing ribs 72 are respectively inserted into the two second fixing grooves 611 and respectively extruded with the groove walls of the two second fixing grooves 611.

In addition, it should be noted that the transmission device can adopt any transmission structure commonly used in the art which can improve the transmission efficiency, such as gears, belts, or magnetic coupling, etc., and the specific selection can be made according to actual needs, and the present embodiment does not make a unique limitation in this regard.

[0051] In some embodiments, referring to Figure 14 , the casing 1 comprises an inner casing 11 and an outer casing 12 which is sleeved on the outer wall of the inner casing 11, the outer casing 12 being transparent, and a coating (not shown in the figure) being formed on the outer surface of the inner casing 11, the coating comprising at least one color. It can be understood that the outer casing 12 is transparent, so that the user can see the outer surface of the inner casing 11 through the outer casing 12, and the outer surface of the inner casing 11 can be coated with colorful coatings, thereby providing the user with rich visual effects and improving the appearance of the electric toothbrush.

[0052] In some embodiments, referring to Figure 15 , Figure 15 is a second exploded schematic view of the electric toothbrush. In addition to the structures given above, the electric toothbrush also comprises other common components of the electric toothbrush in the art, such as a main board 9, an induction copper foil 10, a diffuser 20, a key 30, a light shield 40, a casing cover 50, a USB cover 60, and a USB female seat 70, etc., and since the application of these components in the electric toothbrush belongs to a relatively mature technology, the present application does not make a detailed description in this regard.

[0053] The above embodiments are only preferred implementations of the present application, and are not the only limitations of the motor support 3, the driving device and related electronic equipment; based on the above embodiments, those skilled in the art can make flexible settings according to actual application scenarios. It can be understood that through the implementation of the above embodiments of the present application, the motor support 3 is composed of the hard rubber end plate 31, the soft rubber end plate 32, the two hard rubber arc-shaped plates 33 and the two soft rubber arc-shaped plates 34, one end of the two hard rubber arc-shaped plates 33 is oppositely and spacedly arranged on the hard rubber end plate 31, the soft rubber end plate 32 is attached to the hard rubber end plate 31, one end of the two soft rubber arc-shaped plates 34 is oppositely and spacedly arranged on the soft rubber end plate 32, the two soft rubber arc-shaped plates 34 are respectively attached to the inner sides of the two hard rubber arc-shaped plates 33, the opposite two sides of the hard rubber arc-shaped plate 33 are respectively provided with the first through slot 331 extending to the central axis of the hard rubber arc-shaped plate 33, the first through slot 331 penetrates the hard rubber arc-shaped plate 33 in the thickness direction, the accommodating space 4 is formed between the two soft rubber arc-shaped plates 34, and the corresponding through holes 35 are respectively arranged on the hard rubber end plate 31 and the soft rubber end plate 32. In actual application, one end of the motor 2 provided with an output shaft can be inserted into the accommodating space 4, so that the two soft rubber arc-shaped plates 34 respectively cover the opposite two sides of the motor 2, and the output shaft of the motor 2 passes through the two through holes 35 out of the accommodating space 4, and is pressed by the motor 2 in the accommodating space 4, so that the two soft rubber arc-shaped plates 34 move away from each other. Since two first through slots 331 are arranged on each hard rubber arc-shaped plate 33, each hard rubber arc-shaped plate 33 has a certain elasticity, so the two hard rubber arc-shaped plates 33 move away from each other under the pressing of the two soft rubber arc-shaped plates 34, but the outer sides of the two hard rubber arc-shaped plates 33 abut against the inner side wall of the shell 1, which limits the movement of the two hard rubber arc-shaped plates 33 away from each other, thereby limiting the movement of the two soft rubber arc-shaped plates 34 away from each other, so that the motor 2, the two soft rubber arc-shaped plates 34, the two hard rubber arc-shaped plates 33 and the inner side wall of the shell 1 are pressed against each other. Thus, the motor 2 can be firmly clamped in the accommodating space 4 between the two soft rubber arc-shaped plates 34, and most of the vibration generated by the motor 2 during operation can be offset by the elasticity of the two soft rubber arc-shaped plates 34 and the two hard rubber arc-shaped plates 33. As can be seen, the motor support 3 of the present application has better fixing effect on the motor 2, and the motor 2 is not easy to loosen, which can effectively reduce the noise of the motor 2 during operation and the vibration of the whole machine. At the same time, the motor support 3 does not need to use buckles, screws and other components, and the assembly is simpler and the cost is lower.
