Detailed Description

Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.

The motor assembly according to the embodiment of the present invention will be described below with reference to fig. 1 to 10, and the present invention also proposes a massage head unit 100 having the motor assembly described above, and further proposes a massage apparatus S having the massage head unit 100 described above, which may be a neck massage apparatus.

As shown in fig. 2 to 4, the motor assembly includes: vibration motor 31 and cushion collar 10, cushion collar 10 includes: the vibration motor includes a first buffer portion 11 and a second buffer portion 12, the second buffer portion 12 is connected to an outer periphery of the first buffer portion 11, the first buffer portion 11 may be substantially circular, and the second buffer portion 12 extends in a direction away from the first buffer portion 11, the first buffer portion 11 and the second buffer portion 12 define a first accommodating space 13, and the vibration motor 31 is accommodated in the first accommodating space 13.

Thus, the vibration motor 31 can vibrate to make the muscle of human body shake under the driving of the vibration motor 31, thereby generating the massage relieving effect. The buffer cover 10 can be coated on the outer side of the vibration motor 31 at a small part, the first buffer part 11 can be coated on one end of the vibration motor 31, for example, one end facing the human body, and the second buffer part 12 can be coated on the periphery of the vibration motor 31, so that the vibration reduction and noise reduction effects can be achieved in multiple directions, and the noise reduction effect can be improved. The cushion collar 10 may be an integrally formed silicone collar.

As shown in fig. 8, the thickness of the first buffer portion 11 is d1, the thickness of the second buffer portion 12 is d2, and d1 and d2 satisfy the following relation: d1 > d 2. That is, the cushion collar 10 is a non-uniform-thickness cushion collar, and has different thicknesses according to different positions.

The thickness d1 of the first buffer part 11 between the end face of the vibration motor 31 and the human body is larger, so that the vibration transmitted to the human body by the vibration motor 31 can be effectively reduced, the vibration amplitude of the human body can be in a proper range, and a better massage effect can be achieved; and thickness d2 that will correspond the second buffer portion 12 of vibrating motor 31 periphery sets up is less a little, can make things convenient for the deformation of second buffer portion 12 like this, for example, when installation vibrating motor 31, the staff can reach the purpose of enlarging first accommodation space 13 through tensile second buffer portion 12, thereby can make the inner periphery of second buffer portion 12 be far greater than vibrating motor 31's periphery, can be so that vibrating motor 31's installation, and at tensile in-process, the tensile force is less, can reduce motor element's the installation degree of difficulty, and can also avoid damaging second buffer portion 12.

The first cushioning portion 11 is formed to have a large thickness so as to support the entire shape of the cushion cover 10, and the second cushioning portion 12 is formed to have a small thickness so that the second cushioning portion 12 is relatively easily elastically deformed.

In addition, one side of the motor component facing the human body can be further provided with a heating element 34, and the heating element 34 can play a role of hot compress on the human body. Because the temperature of the heat generating member 34 is high, the thickness d1 of the first buffer portion 11 to be contacted with the heat generating member is larger, the heat transferred to the vibration motor 31 by the heat generating member 34 can be effectively reduced, and the heat insulation requirement of the second buffer portion 12 of the buffer sleeve 10 is smaller, so that the arrangement is smaller.

Further, d1 and d2 satisfy the relationship: d1 is more than or equal to 1mm and less than or equal to 1.6mm, and d2 is more than or equal to 0.3mm and less than or equal to 1 mm. In this way, the first cushioning portion 11 can effectively play a role of vibration and noise reduction, and the first cushioning portion 11 can have such a thickness as to be advantageous in maintaining the overall shape of the cushion cover 10. Through being greater than 0.3mm with the thickness of second buffer 12, can make things convenient for the shaping of second buffer 12, can reduce and avoid appearing the colloid and can not appear the condition of scarce material and shrinkage cavity to and when second buffer 12 thickness is greater than 1mm, can lead to motor element' S diameter great, further lead to the first unit 100 of massage size great, be unfavorable for the global design of massage appearance S.

As shown in fig. 3 to 5, the motor assembly further includes: and a first heat insulating pad 32, the first heat insulating pad 32 being disposed between one end of the vibration motor 31 and the first buffer portion 11 to insulate heat between the vibration motor 31 and the first buffer portion 11. That is, the cushion cover 10 and the first heat insulating mat 32 are provided between the heat generating member 34 and the vibration motor 31, so that the heat insulating and cushioning effects between the heat generating member 34 and the vibration motor 31 can be improved. The first heat insulation pad 32 is adhered to the vibration motor 31, and when the vibration motor 31 is assembled in the cushion cover 10, the two are not easy to relatively shift, and are easier to be installed in place. The first insulation pad 32 may be a circular pad, and the end surface facing the vibration motor 31 and the end surface of the vibration motor 31 may be perfectly matched.

Alternatively, as shown in fig. 6 and 7, the damper groove 19 is opened in the outer peripheral surface of the second buffer portion 12. That is, providing the relief groove 19 on the outer peripheral surface of the second buffer portion 12 can reduce the material used at the second buffer portion 12, can reduce the thickness of the second buffer portion 12, and further weaken the deformation resistance of the second buffer portion 12, which can facilitate the mounting of the vibration motor 31. In addition, the material reducing groove 19 can reduce the production cost of the cushion collar 10.
