Referring to fig. 1, fig. 2, fig. 3, fig. 4 and fig. 6, the present invention provides a vibration isolation pad 10 applied to an electric fan 100, wherein the electric fan 100 includes a mesh enclosure 30 and a motor assembly 50, the motor assembly 50 includes a motor front shell 51 and a motor body 53, the motor front shell 51 is connected to the mesh enclosure 30, and the motor body 53 is connected to the motor front shell 51.
In an embodiment of the present invention, the vibration isolating pad 10 includes a buffer 11, and the buffer 11 includes a first buffer portion 111 and a second buffer portion 113; the first buffer part 111 is used for abutting between the motor body 53 and the motor front shell 51; the second buffer portion 113 is configured to abut between the motor front case 51 and the mesh cover 30.
In an embodiment of the present invention, the buffer 11 is made of an elastic material (for example, a rubber material or a silicone material), so that when the vibration generated by the external object is transmitted to the first buffer portion 111 and the second buffer portion 113, the first buffer portion 111 and the second buffer portion 113 can be deformed correspondingly to block the vibration from being continuously transmitted from the first buffer portion 111 and the second buffer portion 113, thereby achieving vibration isolation of the motor assembly 50. The first buffer portion 111 is configured to abut between the motor body 53 and the motor front case 51 to realize primary vibration isolation, and the second buffer portion 113 is configured to abut between the motor front case 51 and the mesh cover 30 to realize secondary vibration isolation, so as to greatly improve the vibration isolation effect of the vibration isolator 10.
When the vibration isolator 10 according to the present invention is applied to the electric fan 100, the first buffer portion 111 of the buffer 11 of the vibration isolator 10 is abutted between the motor body 53 of the motor assembly 50 and the motor front case 51, so that the vibration generated during the operation of the motor body 53 can be buffered, and the possibility that the vibration of the motor body 53 is transmitted to the motor front case 51 can be reduced. Meanwhile, the second buffer part 113 in the buffer part 11 of the vibration isolator 10 abuts between the motor front shell 51 and the mesh enclosure 30, so that the vibration of the motor front shell 51 driven by the vibration of the motor body 53 can be buffered, and the possibility that the vibration of the motor front shell 51 is transmitted to the mesh enclosure 30 is reduced.
In the vibration isolation pad 10 of the present embodiment, the first buffer portion 111 and the second buffer portion 113 of the buffer member 11 buffer and isolate vibration of the motor assembly 50 twice, so that the vibration isolation effect of the motor assembly 50 is greatly improved, the possibility that vibration generated by the motor assembly 50 during operation is transmitted to the mesh enclosure 30 and causes the mesh enclosure 30 to resonate to cause the shaking of the electric fan 100 is reduced, and the shaking of the electric fan 100 is effectively improved. Moreover, the vibration isolation of the vibration source of the electric fan 100 by the vibration isolation pad 10 reduces the requirement for the dynamic unbalance amount of the motor body 53, and can greatly improve the inclusion that the dynamic unbalance amount of the motor body 53 does not reach the standard. Therefore, the problem that the dynamic unbalance amount is not up to standard due to the difficulty in consistency in process design can be solved, and the possibility of recurrence of the shaking phenomenon of the electric fan 100 is reduced.
Referring to fig. 2, fig. 3 and fig. 4, in an embodiment of the present invention, the buffer 11 further includes a buffer main body portion 115, the buffer main body portion 115 is configured to penetrate through the front shell 51 of the motor, and the buffer main body portion 115 is defined to have two opposite ends; the first buffer portion 111 is provided at one end of the buffer main body portion 115, and the second buffer portion 113 is provided at the other end of the buffer main body portion 115.
It can be understood that the first buffer part 111 and the second buffer part 113 are connected by the buffer main body, so that the two parts can be formed into a whole and can be mounted on the front shell 51 of the motor in one step, thereby improving the mounting efficiency of the vibration isolating pad 10. In this case, the motor front case 51 may be provided with a mounting hole 51a, and the buffer body may be inserted into the mounting hole 51a and abut against a wall of the mounting hole 51 a. In addition, the present invention is not limited to this, and in another embodiment, when the buffer material 11 does not include the buffer main body portion 115, the first buffer portion 111 and the second buffer portion 113 may be two independent components and respectively installed between the motor body 53 and the motor front case 51 and between the motor front case 51 and the mesh cover 30. In this case, when one of the two is damaged, only the damaged one can be replaced, thereby reducing the replacement cost.
Referring to fig. 4, fig. 5 and fig. 6, in an embodiment of the present invention, the first buffer portion 111 and the second buffer portion 113 are both disposed in a ring shape.
It is to be understood that the first buffer portion 111 and the second buffer portion 113 are each disposed in a ring shape, i.e., circumferentially disposed along the peripheral edge of the buffer main body portion 115. In this case, the first buffer portion 111 has a large contact area with the motor body 53 and the motor front case 51, and the second buffer portion 113 has a large contact area with the motor front case 51 and the mesh cover 30, so that the vibration damping effect of the first buffer portion 111 and the second buffer portion 113 can be improved. The first buffer portion 111 and the second buffer portion 113 may be respectively sleeved at two ends of the buffer main body portion 115, and the first buffer portion 111 and the second buffer portion 113 may be end surfaces respectively connected to two ends of the buffer main body portion 115. In addition, the present invention is not limited to this, and in other embodiments, the first buffer portion 111 may be formed of a plurality of segments that are disposed on the side circumferential surface of the buffer main body portion 115 at intervals, or may be formed of one segment that is disposed at an angle to the buffer main body portion 115; similarly, the second buffer portion 113 may be formed of a plurality of segments that are arranged around the side circumference of the buffer main body portion 115 at intervals, or may be formed of one segment that is arranged at an angle to the buffer main body portion 115.
Referring to fig. 4 and 6 in combination, in an embodiment of the invention, the buffer main body 115 includes a first segment 1151 and a second segment 1153; the second segment 1153 is connected to one end of the first segment 1151, and the area of the cross section of the second segment 1153 is larger than that of the first segment 1151; the first buffer portion 111 is connected to an end of the first segment 1151 remote from the second segment 1153, and the second buffer portion 113 is connected to an end of the second segment 1153 remote from the first segment 1151.
It is understood that the buffer main portion 115 is composed of a first segment 1151 and a second segment 1153, and the cross-sectional area of the second segment 1153 is larger than that of the first segment 1151, so that the outer side wall of the first segment 1151, the wall surface of the second segment 1153 facing the first segment 1151, and the wall surface of the first buffer portion 111 facing the second buffer portion 113 enclose a limiting groove 11 a. Referring to fig. 2 and fig. 3 in combination, at this time, the hole wall of the mounting hole 51a of the front motor housing 51 may be convexly provided with a limiting rib 511, and the limiting rib 511 is abutted and embedded in the limiting groove 11a, so that the clamping limiting fixation of the vibration isolating pad 10 is realized, and the stability of the arrangement of the vibration isolating pad 10 is improved. The limiting rib 511 may be in a ring shape to increase the contact area with the groove wall of the limiting groove 11a and improve the clamping limiting effect. The limiting rib 511 may also be formed by a plurality of segments arranged around the hole wall of the mounting hole 51a at intervals, so as to reduce the raw material used for forming the limiting rib 511. Of course, in other embodiments, a limiting groove 11a may be further formed on the side circumferential surface of the second segment 1153; alternatively, when the cross-sectional areas of the buffer main body portion 115 are equal (it can be said that the cross-sectional areas of the first segment 1151 and the second segment 1153 are equal), the stopper groove 11a may be recessed at an arbitrary position on the side circumferential surface of the buffer main body portion 115, and the stopper rib 511 may be provided at a corresponding position. When the stopper groove 11a is not formed in the cushion body, the vibration damping mount 10 may be fixed by being held only by the first cushion portion 111 and the second cushion portion 113 abutting against both surfaces of the motor front case 51 through which the mounting hole 51a penetrates.
Referring to fig. 3, in an embodiment of the invention, the cross-sectional area of the second segment 1153 is gradually decreased in a direction that the first segment 1151 is close to the second segment 1153.
It will be appreciated that the cross-sectional area of the second segment 1153 is tapered such that the lateral periphery of the second segment 1153 forms a lead-in ramp. In this case, when the vibration insulator 10 is mounted on the motor front case 51, the vibration insulator 10 can be accurately mounted on the mounting hole 51a of the motor front case 51 gradually by the guide of the guide slope, thereby improving the convenience of mounting the vibration insulator 10. When the vibration isolation pad 10 and the motor front shell 51 are of an integrated structure, namely, when the vibration isolation pad and the motor front shell 51 are manufactured through integrated forming, the hole wall of the mounting hole 51a is correspondingly formed to be an inclined surface through the arrangement of the guide inclined surface, so that the contact area between the vibration isolation pad 10 and the motor front shell 51 is increased, and the fastening performance between the vibration isolation pad and the motor front shell 51 is improved. The entire lateral surface of the second segment 1153 may be a guiding slope from the end close to the first segment 1151 to the end far from the first segment 1151, or a partial lateral surface of the second segment 1153 may be a guiding slope from the end close to the first segment 1151 to the end far from the first segment 1151. Of course, the present application is not limited thereto, and in other embodiments, the cross-sectional areas of the second segment 1153 are equal.
Referring to fig. 3, in an embodiment of the invention, the first buffer portion 111 and the second buffer portion 113 are both sleeved on the buffer main body portion, the buffer main body portion 115 is provided with a connection hole 115a, and the connection hole 115a penetrates through end surfaces of two opposite ends of the buffer main body portion 115.
It is understood that the connection hole 115a is configured to allow a fastener (e.g., a screw or a snap) connecting the motor body 53 and the motor front case 51 to pass therethrough and abut against the fastener. At this time, it is possible to reduce the possibility that the vibration generated by the motor body 53 during operation is transmitted to the motor front case 51 between the fastening members, thereby further improving the vibration isolating effect of the vibration isolating pad 10. Meanwhile, the fastening member penetrates through the buffer main body 115, and the vibration isolator 10 can be further limited and fixed by the fastening member, so that the stability of fixing the vibration isolator 10 is further improved.
In an embodiment of the present invention, the connection hole 115a includes a first hole segment 115c and a second hole segment 115e, the first hole segment 115c penetrates through an end surface of the buffer main body portion 115 near one end of the first buffer portion 111; the second hole section 115e penetrates through an end surface of the buffer main body portion 115 near one end of the second buffer portion 113 and communicates with the first hole section 115c, and the cross-sectional area of the second hole section 115e is larger than that of the first hole section 115 c.
It is understood that the connection hole 115a is composed of a first hole segment 115c and a second hole segment 115e, and the cross-sectional area of the second hole segment 115e is larger than that of the first hole segment 115c, so that the shape of the connection hole 115a can be adapted to the shape of a fastener (e.g., a screw). The fastener can be embedded in the connecting hole 115a, so that the fastener is better wrapped and abutted through the hole wall of the connecting hole 115a, the possibility that the fastener is in contact with the motor front shell 51 and the mesh enclosure 30 is reduced, and the vibration isolation effect of the fastener is improved. The first hole segment 115c may be partially disposed in the first segment 1151 of the buffer main body 115, partially disposed in the second segment 1153, and the second hole segment 115e may be entirely disposed in the second segment 1153. At this time, the area of the cross section of the second segment 1153 is larger than that of the cross section of the first segment 1151, so that the wall thickness of the buffer main body portion 115 is uniform, the buffer main body portion 115 is convenient to mold, and meanwhile, the overall volume of the buffer main body portion 115 is relatively small, raw materials needed to be used in molding are reduced, and manufacturing cost is reduced. Of course, the present application is not limited thereto, and in other embodiments, the cross-sectional areas of the connecting holes 115a may be equal, and the fastening portion is located outside the connecting hole 115a, and at this time, the position of the mesh cover 30 corresponding to the fastening portion is a recessed avoidance space.
In an embodiment of the present invention, the first buffer portion 111, the buffer main body portion 115, and the second buffer portion 113 are an integral structure.
It can be understood that such an arrangement can increase the connection strength of the first buffer portion 111, the buffer main body portion 115, and the second buffer portion 113, thereby increasing the overall strength of the buffer member 11 and contributing to the extension of the service life. Meanwhile, the arrangement also enables the first buffer part 111, the buffer main body part 115 and the second buffer part 113 to be manufactured by integral molding, thereby simplifying the processing technology of the buffer 11 and improving the production efficiency. Of course, the present invention is not limited to this, and in other embodiments, the first buffer portion 111, the buffer main body portion 115, and the second buffer portion 113 may be separately provided, and may be fixed by bonding with glue, or may be fixed by snap-fitting.
Referring to fig. 5, in an embodiment of the present invention, the cross-sections of the first buffer portion 111, the buffer main body portion 115 and the second buffer portion 113 are all circular.
It can be understood that the first buffer portion 111, the buffer main body portion 115, and the second buffer portion 113 are all cylindrical, so that the shape of the buffer material 11 is relatively regular, and the molding and manufacturing are facilitated. Meanwhile, the arrangement is also such that the side circumferential surface of the buffer member 11 is uniform throughout, so that the mounting directivity does not need to be considered when the buffer member is mounted on the motor front shell 51, thereby being beneficial to improving the mounting efficiency of the buffer member 11. Of course, the present invention is not limited thereto, and in other embodiments, the cross section of the first buffer portion 111, the buffer main body portion 115, and the second buffer portion 113 may be square or other shapes.
Referring to fig. 6, in an embodiment of the invention, a wall surface of the first buffer portion 111 facing away from the second buffer portion 113 is flush with an end surface of the buffer main body portion 115 near an end of the first buffer portion 111.
It can be understood that the surface of the first buffer portion 111 and the end surface of the buffer main body portion 115 (the surface of the first segment 1151 deviating from the second segment 1153) are flush, so that the first buffer portion 111, the buffer main body portion 115 and the surface of the motor body 53 facing the motor front shell 51 can be in good abutting joint, the abutting joint effect of the first buffer portion and the buffer main body portion 115 is improved, and the vibration isolation effect of the motor body 53 is improved. Meanwhile, the arrangement can ensure that the position is relatively flat, so that the processing and forming of the buffer piece 11 are convenient. Similarly, the wall surface of the second buffer portion 113 facing away from the first buffer portion 111 may also be flush with the end surface of the buffer main body portion 115 near the end of the second buffer portion 113 (the surface of the second segment 1153 facing away from the first segment 1151), so that the second buffer portion 113, the buffer main body portion 115 and the surface of the mesh cover 30 facing the motor front shell 51 are in good abutment, and the abutment effect of the two is improved to improve the vibration isolation effect of the motor front shell 51.
Referring to fig. 4 and 5, in an embodiment of the invention, the number of the buffering members 11 is at least two, and the vibration isolator 10 further includes a connecting member 13, wherein the connecting member 13 connects the at least two buffering members 11.
It can be understood that the number of the buffers 11 is at least two, so that the vibration isolating effect of the vibration isolating pad 10 on the motor assembly 50 is improved by increasing the number of the buffers 11. The connecting member 13 is disposed such that at least two buffering members 11 can be integrally formed, so that the vibration isolating pad 10 can be mounted to the front case 51 of the motor at one time to improve mounting efficiency.
