Description

Technical Field

[0001] The utility model relates to the technical field of massagers, and particularly to a massage device. Background Art

[0002] A vibrating massager is a massage device that uses a massage head to vibrate periodically to pound the human body. It simulates manual massage and can achieve effects such as relaxing muscles, soothing nerves, and promoting blood circulation, which helps to improve sub-healthy conditions of the human body and relieve various acute and chronic pains and muscle soreness problems. During the vibration of the massage head, the rest of the components on the massager will inevitably vibrate synchronously with a relatively large amplitude. For example, when using a handheld massager, the user's hand is continuously impacted, resulting in uncomfortable sensations such as numbness, which affects the user experience.

[0025] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] The present utility model discloses a massage device with a shock-absorbing effect. This massage device can be used both on wearable devices, such as wearable neck massagers, waist massagers, knee massagers, etc., and on non-wearable devices, such as hand-held massagers like percussion massagers, small foot massagers, lumbar support massagers, and massage chairs. Specifically, please refer to Figure 1 and Figure 2, the massage device of this embodiment includes a housing 100, a vibration assembly 200, an elastic massage head 300, and a mounting assembly 400. Among them, the housing 100 is used to provide a receiving place for the vibration assembly 200 to achieve encapsulation and protection of the vibration assembly 200; the vibration assembly 200 is used to provide power for the elastic massage head 300 to vibrate, so that the elastic massage head 300 can vibrate and act on the human body to achieve percussion massage on the human body; the mounting assembly 400 serves as the connection part between the massage device of this embodiment and the structural framework of the wearable device or non-wearable device, and realizes the installation of the massage device on the wearable device or non-wearable device.

[0027] Please further combine Figures 1-4 , a receiving cavity is formed in the housing 100, and an annular fixing groove 130 is provided on the outer surface of the housing 100. In one embodiment, the outer surface of the housing 100 protrudes to form a first limiting ring 110 and a second limiting ring 120 located above the first limiting ring 110. An annular fixing groove 130 is formed between the first limiting ring 110 and the second limiting ring 120. The first limiting ring 110 and the second limiting ring 120 are used to provide a limiting connection part between the housing 100 and the mounting assembly 400. In another embodiment, the outer surface of the housing 100 is recessed to form an annular fixing groove 130. The vibration assembly 200 includes a motor 210 and an eccentric wheel 220 received in the receiving cavity. The eccentric wheel 220 is fixedly connected to the output shaft of the motor 210, and the outer surface of the motor 210 abuts against the inner surface of the housing 100. It should be noted that in this embodiment, the eccentric wheel 220 extends into the receiving cavity and is fixedly connected to the output shaft of the motor 210, and the eccentric wheel 220 does not contact the inner surface of the housing 100 to avoid interference from the inner surface of the housing 100 to the eccentric rotation of the eccentric wheel 220. The elastic massage head 300 covers the housing 100. The inner surface of the elastic massage head 300 abuts against the top surface and the circumferential side surface of the housing 100, and the bottom of the elastic massage head 300 is located above the annular fixing groove 130. The elastic massage head 300 is used to provide the contact part between the massage device and the human body or the acting part of the massage device on the human body.

[0028] The installation component 400 includes a support member 410 and an elastic annular bracket 420. A plurality of feet 411 are arranged at intervals on the upper surface of the support member 410. The elastic annular bracket 420 is located above the support member 410 and fixedly connected to each foot 411. The housing 100 is inserted into the central hole 421 of the elastic annular bracket 420, and the edge of the central hole 421 is snapped into the annular fixing groove 130 and in limiting abutment with the inner surface of the annular fixing groove 130. After the elastic annular bracket 420 is connected to the support member 410, the connection part of the two is in an I-shaped structure. When the annular fixing groove 130 is formed by the first limiting ring 110 and the second limiting ring 120, after the lower part of the housing 100 is inserted into the central hole 421 of the elastic annular bracket 420, the upper surface of the first limiting ring 110 abuts against the lower opening edge of the central hole 421 of the elastic annular bracket 420, and the lower surface of the second limiting ring 120 abuts against the upper opening edge of the central hole 421 of the elastic annular bracket 420. The outer surface of the housing 100 abuts against the inner surface of the central hole 421 in the area between the first limiting ring 110 and the second limiting ring 120. In this way, through the mutual restraint of the first limiting ring 110, the second limiting ring 120 and the central hole 421 of the elastic annular bracket 420, the limiting installation of the housing 100 on the elastic annular bracket 420 can be realized, so as to prevent the housing 100 from shaking relative to the elastic annular bracket 420 in the horizontal plane and the vertical direction.

[0029] When the motor 210 works, the output shaft of the motor 210 drives the eccentric wheel 220 to rotate eccentrically. During this process, the center of gravity of the connection body composed of the motor 210 and the eccentric wheel 220 changes periodically, causing the eccentric wheel 220 to vibrate. Since the eccentric wheel 220 is in contact with the motor 210, the motor 210 abuts against the inner surface of the housing 100, and the elastic massage head 300 further contacts the housing 100. Therefore, the vibration of the eccentric wheel 220 will be sequentially transmitted to the elastic massage head 300 through the motor 210 and the housing 100, causing the elastic massage head 300 to vibrate and massage the human body. Since the vibration of the eccentric wheel 220 is transmitted to the elastic massage head 300, when the vibration is transmitted from the housing 100 to the elastic massage head 300, the vibration is synchronously transmitted to the elastic annular bracket 420 and the support member 410. By designing the connection part of the elastic annular bracket 420 and the support member 410 as an I-shaped structure, because the I-shaped structure has a damping effect, the vibration transmitted from the elastic annular bracket 420 to the support member 410 can be buffered, so as to achieve the purpose of weakening the vibration of the support member 410.

[0030] In order to maximize the vibration amplitude of the elastic massage head 300, in this embodiment, the first limiting ring 110 and the second limiting ring 120 are located in the lower region of the outer surface of the housing 100. In this way, the distance from the connection part of the housing 100 and the elastic annular bracket 420 to the eccentric wheel 220 is extended, so as to reduce the influence of the limit of the elastic annular bracket 420 on the vibration of the housing 100.

[0031] In one embodiment, the upper surface of the support leg 411 abuts against the lower surface of the elastic annular bracket 420, and the two are fixedly connected by screws passing through the elastic annular bracket 420 and inserted into the support leg 411. In another embodiment, an annular step 412 penetrating the upper surface of the support leg 411 is provided on the upper part of the support leg 411, and a plurality of mounting holes 422 corresponding to each support leg 411 are formed in the elastic annular bracket 420. The upper part of the support leg 411 is inserted into the mounting hole 422, and the annular step 412 abuts against the lower surface of the elastic annular bracket 420. The elastic annular bracket 420 is fixedly connected to the support leg 411 through a fastener 423. The fastener 423 is inserted into the support leg 411 from above the support leg 411 and abuts against the upper surface of the elastic annular bracket 420. By providing the annular step 412 on the support leg 411, it is convenient to quickly position the elastic annular bracket 420 and the support member 410, so as to reduce the assembly difficulty of the two. In this embodiment, the fastener 423 can be a screw, including a stud (i.e., the tail of the fastener 423) and a nut fixed on the top of the stud (i.e., the head of the fastener 423). In this way, during the assembly process of the support leg 411 and the elastic annular bracket 420, the stud is inserted into the support leg 411 through the upper surface of the support leg 411, and the lower surface of the nut abuts against the upper opening edge of the mounting hole 422, so as to lock the support leg 411 and the elastic annular bracket 420 through the fastener 423. Further preferably, the top of the support leg 411 is located in the mounting hole 422, and the distance between the upper surface of the support leg 411 and the upper surface of the elastic annular bracket 420 is 0.2-1 mm. That is to say, the upper surface of the support leg 411 is lower than the upper surface of the elastic annular bracket 420. In this way, when the tail of the fastener 423 is inserted into the support leg 411 and the head of the fastener 423 abuts against the edge of the mounting hole 422, the lower surface of the head of the fastener 423 does not abut against the upper surface of the support leg 411, which can further reduce the transmission of vibration to the support leg 411 and the support member 410 and improve the shock absorption effect of the whole machine.

[0032] In one embodiment, the housing 100 is made of an elastic material as a whole, and a through hole is provided at the top of the housing 100. During the assembly process of the massage device, the housing 100 can be stretched to expand the through hole, so as to put the motor 210 and the eccentric wheel 220 into the accommodating cavity of the housing 100 through the expanded through hole. Subsequently, the elastic massage head 300 is covered on the top of the housing 100 and the through hole is blocked to realize the encapsulation of the motor 210.

[0033] In another embodiment, the housing 100 includes a left housing 140 and a right housing 150. The left housing 140 and the right housing 150 are joined together to enclose a receiving cavity. The outer surface of the motor 210 abuts against the inner surface of the left housing 140 and the inner surface of the right housing 150. The inner surface of the elastic massage head 300 abuts against the top surface and the circumferential side surface of the left housing 140 and the top surface and the circumferential side surface of the right housing 150. The outer surfaces of the lower parts of the left housing 140 and the right housing 150 respectively abut against the inner surface of the central hole 421. In this embodiment, the housing 100 can be made of an elastic material or a rigid material such as ABS plastic. The housing 100 is designed as a detachable left housing 140 and right housing 150. During the assembly process of the massage device, the motor 210 and the eccentric wheel 220 are encapsulated by the joined and fixed left housing 140 and right housing 150. The upper part of the connection structure of the left housing 140 and the right housing 150 is limited by the elastic massage head 300, and the lower part of the connection structure of the left housing 140 and the right housing 150 is limited by the elastic ring bracket 420, ensuring the stability of the connection structure of the left housing 140 and the right housing 150 and the reliability of the support and protection of the motor 210. During the assembly process of the massage device, it is only necessary to respectively arrange the left housing 140 and the right housing 150 on both sides of the motor 210 and join them together, and then further use the elastic massage head 300 and the elastic ring bracket 420 to position the housing 100 components, that is, to realize the encapsulation of the motor 210 and the assembly of the massage device, reducing the difficulty of assembling the housing 100 components and their assembly with the elastic massage head 300 and the elastic ring bracket 420. In addition, in this embodiment, the elastic ring bracket 420 can also be used for axially fixing the housing 100 to reduce the axial tremor of the housing.

[0034] It should be noted that in this embodiment, the vertical cross-section of the elastic massage head 300 is in an n-shaped structure, and the width inside the elastic massage head 300 is slightly smaller than the width of the housing 100. In this way, when the elastic massage head 300 covers the housing 100, the elastic massage head 300 deforms and presses the outer surfaces of the left housing 140 and the right housing 150 to improve the stability of the upper connection of the left housing 140 and the right housing 150. Similarly, the width of the central hole 421 of the elastic ring bracket 420 is slightly smaller than the width of the housing 100, so as to use the elastic deformation of the edge of the central hole 421 of the elastic ring bracket 420 to press the outer surfaces of the left housing 140 and the right housing 150 to improve the stability of the lower connection of the left housing 140 and the right housing 150. Of course, convex teeth or grooves can also be provided on the surface of the left housing 140 that cooperates with the right housing 150, and corresponding grooves or convex teeth can be provided on the surface of the right housing 150 that cooperates with the left housing 140, and the connection stability can be improved through the concave-convex cooperation of the two.

[0035] In one embodiment, the left housing 140 and the right housing 150 are respectively in a U-shaped structure. A first sector ring structure 141 is provided on the inner surface of the left housing 140, and a second sector ring structure 151 is provided on the inner surface of the right housing 150. The first sector ring structure 141 and the second sector ring structure 151 jointly partition the accommodation cavity to form an eccentric area 160 and a driving area 170 located below the eccentric area 160. A through hole 180 is formed between the first sector ring structure 141 and the second sector ring structure 151. The motor 210 is received in the driving area 170, and the outer surface of the motor 210 is respectively in contact with the inner surface of the left housing 140, the inner surface of the right housing 150, the lower surface of the first sector ring structure 141, and the lower surface of the second sector ring structure 151, so as to further increase the contact area between the inner surface of the housing 100 and the outer surface of the motor 210, and at the same time realize the horizontal and vertical position-limiting of the motor 210 to prevent the motor 210 from shaking driven by the eccentric wheel 220. The eccentric wheel 220 extends into the eccentric area 160 and the distance from the outer surface of the eccentric wheel 220 to the inner surface of the eccentric area 160 is greater than zero. The output shaft of the motor 210 passes through the through hole 180 and is drivingly connected to the eccentric wheel 220. Further, at least one first protrusion 142 is provided on the inner surface of the left housing 140 below the first sector ring structure 141, and at least one second protrusion 152 is provided on the inner surface of the right housing 150 below the second sector ring structure 151. The first protrusion 142 and the second protrusion 152 are respectively in contact with the circumferential side surface of the motor 210. In this way, while transmitting the vibration of the motor 210 to the housing 100, the side position-limiting of the motor 210 can be realized without the outer side surface of the motor 210 being in full contact with the inner surface of the housing 100, reducing the positioning difficulty of the motor 210.

[0036] In this embodiment, the elastic annular bracket 420 is made of an elastic material with a Shore hardness of 30-60 degrees. Further preferably, the elastic annular bracket 420 is made of silica gel with a Shore hardness of 30-60 degrees. Of course, other elastic materials can also be used to reduce the transmission of vibration to the support 410. Please combine Figure 3 with Figure 5 , the cross-sectional area of the eccentric wheel 220 accounts for 35%-55% of the area covered by the eccentric wheel 220 rotating one circle. The area covered by the eccentric wheel 220 rotating one circle is the area of a circle with the distance from the farthest part of the eccentric wheel 220 from its rotation center to the rotation center as the radius. Through actual use verification, when the cross-sectional area of the eccentric wheel 220 accounts for 35%-55% of the area covered by the eccentric wheel 220 rotating one circle, the vibration effect of the elastic massage head 300 is better.

[0037] In addition, according to the different massage parts and usage scenarios, one end of the elastic massage head 300 away from the elastic annular bracket 420 can be designed as a spherical head structure, a Y-shaped structure, a disc-shaped structure, etc. To improve the comfort of human body massage, the elastic massage head 300 is made of an elastic material to avoid damaging the human muscles or skin. In one embodiment, the elastic massage head 300 is made of a foam material, and a heating sheet is arranged inside the elastic massage head 300 so as to perform hot compress on the massage part while massaging, thereby enhancing the massage effect. In another embodiment, the elastic massage head 300 is made of a silica gel material, and lamp beads or / and heating sheets are arranged inside the elastic massage head 300. Thus, while massaging the user, hot compress or / and lighting effects can be provided to improve the user's massage experience. In addition, since the inner surface of the elastic massage head 300 abuts against the upper surface and the outer side surface of the housing 100, when it is necessary to increase the heat generation and the lighting effect of the lamp beads, during the processing process of the elastic massage head 300 (such as the injection molding process), the heating sheet and the lamp beads can be embedded in the elastic massage head 300, that is, the heating sheet and the lamp beads are placed in the production mold of the massage head and the corresponding glue solution is poured in to form an elastic massage head 300 with a heating sheet and lamp beads arranged inside.

[0038] The connection part between the elastic annular bracket 420 and the support member 410 of the above massage device is designed as an I-shaped structure, which can effectively reduce the transmission of vibration to the support member 410, is beneficial to only retain the vibration generated by the elastic massage head 300 part, reduce the vibration transmitted to the massage device body, and reduce the vibration impact generated by non-massage heads when the user uses the shock-absorbing massage device, thereby improving the user's experience of using the massage device.

[0039] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0040] The above-described embodiments only express several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
