Description

[Technical Field]

[0001] The present invention relates to an anti-vibration and sound-proofing device, a bracket with anti-vibration and sound-proofing functions, and a fixing structure for a vehicle electric accessory. [Background technology]

[0002] Recently, with the spread of electric vehicles (EVs), the interior of vehicles has become quieter, but the noise and vibration generated when electric auxiliary machinery installed in the vehicle is operating has become a problem.

[0003] When a vehicle electric accessory operates, it may generate operating noise. If this operating noise enters the vehicle cabin, it may be disturbing to the occupants. Furthermore, when the vehicle electric accessory operates, it may vibrate. This vibration may be transmitted to a bracket connecting the vehicle electric accessory to the vehicle body, and further to the vehicle body, causing the vehicle electric accessory, the bracket, and the vehicle body to vibrate, which may result in noise being generated from the vehicle electric accessory, the bracket, and the vehicle body.

[0004] Patent Document 1 describes a technology for reducing noise and vibrations generated when a vehicle electric accessory is in operation, in which the outer surface of the vehicle electric accessory is covered with a soundproof cover and vibration-damping material is interposed between the bracket that attaches the vehicle electric accessory to the vehicle body and the vehicle body.

[0005] In the technology disclosed in Patent Document 1, a vehicle electric accessory is fixed to the vehicle body by a support bracket. A vibration-damping material is interposed between the support bracket and the vehicle body. The soundproof cover has a first cover portion and a second cover portion. The first cover portion is disposed between the support bracket and the vehicle body. The second cover portion covers the outer peripheral surface of the vehicle electric accessory on the side opposite the vehicle body from the support bracket. The first cover portion and the second cover portion cover the entire vehicle electric accessory. [Prior art documents] [Patent documents]

[0016] (Embodiment 1) 1. Schematic configuration of vibration and soundproofing device 10a As shown in FIG. 1 , an anti-vibration and soundproofing device 10a (an example of a bracket with anti-vibration and soundproofing functions) according to this embodiment is attached to a vehicle electric accessory 20 and has the functions of suppressing transmission of vibrations generated by the vehicle electric accessory 20 to a vehicle body B of a vehicle (not shown) and suppressing transmission of noise generated by the vehicle electric accessory 20 to the outside. The anti-vibration and soundproofing device 10a according to this embodiment can be applied to any vehicle electric accessory 20, such as a motor or a compressor. In this embodiment, a compressor will be used as an example of the vehicle electric accessory 20. In the following description, the direction indicated by arrow X is the forward direction, the direction indicated by arrow Y is the leftward direction, and the direction indicated by arrow Z is the upward direction. Furthermore, in the following description, when multiple identical components are used, only some of the components will be designated by reference numerals, and the reference numerals will be omitted for other components.

[0017] 2. Vehicle electric auxiliary machine 20 As shown in FIG. 1 , the vehicle electric accessory 20 includes a main body 21 and a protruding portion 22 that protrudes downward from the outer surface of the main body 21. The main body 21 is formed in a generally cylindrical shape. The protruding portion 22 is formed in a generally rectangular shape. The main body 21 houses a rotating shaft member 21a that rotates about a rotation axis C. The rotation axis C of the rotating shaft member 21a extends in the left-right direction. However, the shape of the main body 21 is not particularly limited, and any shape can be adopted. The shape of the protruding portion 22 is not particularly limited, and any shape can be adopted. Furthermore, the protruding portion 22 can be formed to protrude in any direction.

[0018] For example, a circuit board (not shown) is housed in the protruding portion 22. However, the member housed in the protruding portion 22 is not limited to a circuit board, and any member can be housed therein.

[0019] An upwardly protruding boss base 21b is formed on the top surface of the main body 21. The boss base 21b is formed in a plate shape. A rearward protruding boss 21c is formed on the left side surface of the boss base 21b. The boss 21c is formed in a cylindrical shape. The boss 21c extends in the front-rear direction and has a female threaded hole 21d that opens rearward.

[0020] 3. Vibration and sound insulation device 10a The vibration and soundproofing device 10a will be described with reference to Figures 1 to 4. The vibration and soundproofing device 10a includes a bracket body 30, a vibration isolator 40, and a soundproofing cover 50.

[0021] 3.1.Bracket body 30 The bracket body 30 is made of a metal such as aluminum or stainless steel. The bracket body 30 is formed into a predetermined shape by bending or casting a metal plate. The bracket body 30 of this embodiment is formed by bending a metal plate.

[0022] 2, the bracket body 30 includes a first mounting portion 31 that is attached to the vehicle electric accessory 20, a second mounting portion 32 that is attached to the vehicle body B, and a third mounting portion 33 to which the soundproof cover 50 is attached. The first mounting portion 31, the second mounting portion 32, and the third mounting portion 33 are integrally formed.

[0023] As shown in FIGS. 1 to 4, the first mounting portion 31 extends in the direction of the rotation axis C of the rotating shaft member 21a (the left-right direction in this embodiment). The first mounting portion 31 in this embodiment is formed in a rectangular shape with the left-right direction as the longitudinal direction and the up-down direction as the short side direction. The first mounting portion 31 has a first main surface 31a that is mounted to the vehicle electric accessory 20. In this embodiment, the front surface of the first mounting portion 31 is the first main surface 31a. The surface of the first mounting portion 31 opposite to the first main surface 31a (the rear surface in this embodiment) is the first back surface 31b.

[0024] The third mounting portion 33 is formed to extend downward from the lower end of the first mounting portion 31. The third mounting portion 33 is formed in a substantially rectangular shape with the left-right direction as the longitudinal direction and the up-down direction as the lateral direction. A soundproof cover 50 is attached to a first main surface 31a of the third mounting portion 33 that continues from the first mounting portion 31. The third mounting portion 33 is formed in a gently curved shape that convexly faces rearward. The front surface of the third mounting portion 33 forms part of a circumference.

[0025] 3 and 4, second mounting portions 32 are formed on the left and right ends of the third mounting portion 33, at the lower edge of the third mounting portion 33, and protrude forward. The second mounting portion 32 includes an extension portion 34 formed in a rectangular shape when viewed from above, and an anti-vibration device mounting portion 35 formed at the front end of the extension portion 34 and formed in a disk shape when viewed from above. The rear end of the extension portion 34 is continuous with the third mounting portion 33, and the front end of the extension portion 34 is continuous with the anti-vibration device mounting portion 35.

[0026] 4, the length dimension in the front-to-rear direction of the extension portion 34 is set so that the center of the vibration isolation device mounting portion 35 is positioned so that it substantially overlaps with the rotation axis C when viewed from above. The center of the vibration isolation device mounting portion 35 and the rotation axis C may be positioned so that they overlap when viewed from above, or they may be positioned so that they can be recognized as substantially overlapping, even if they do not completely overlap when viewed from above.

[0027] In this embodiment, the two second mounting portions 32 are disposed on both end sides in the direction of the rotational axis C of the rotating shaft member 21a with respect to the vehicle electric accessory 20. However, for example, a configuration may be adopted in which both of the two second mounting portions 32 are disposed on one end side in the direction of the rotational axis C of the rotating shaft member 21a with respect to the vehicle electric accessory 20, and the second mounting portions 32 can be disposed in any position. Furthermore, the number of second mounting portions 32 is not particularly limited and may be one, or three or more.

[0028] The second mounting portion 32 has a second main surface 32a that is attached to the vehicle body B of the vehicle. In this embodiment, the second main surface 32a is the lower surface of the second mounting portion 32. Furthermore, the surface of the second mounting portion 32 opposite the second main surface 32a (the upper surface in this embodiment) is the second back surface 32b. In this embodiment, the first main surface 31a and the second main surface 32a form opposite surfaces of the bracket body 30. Furthermore, in this embodiment, the first main surface 31a and the second back surface 32b are connected at an angle.

[0029] 3.2. Vibration isolation device 40 4, the vibration-damping device 40 is attached to the vibration-damping device attachment portion 35 of the second attachment portion 32 so as to penetrate therethrough in the vertical direction. The vibration-damping device 40 includes an outer cylinder 41, an inner cylinder 42 arranged inside the outer cylinder 41, and an elastic body 43 arranged between the outer cylinder 41 and the inner cylinder 42 to connect the outer cylinder 41 and the inner cylinder 42.

[0030] The outer cylinder 41 and the inner cylinder 42 are made of a hard material such as metal or synthetic resin. The outer cylinder 41 and the inner cylinder 42 are formed in a substantially cylindrical shape. The vertical length of the inner cylinder 42 is set to be greater than the vertical length of the outer cylinder 41.

[0031] The outer tube 41 is attached to the vibration isolation device attachment portion 35 provided on the second attachment portion 32 of the bracket main body 30. The inner tube 42 is attached to the vehicle body B. A bolt (not shown) is inserted into the inner tube 42 from above, and the bolt is screwed into a nut (not shown) arranged on the vehicle body B or a female threaded hole (not shown) formed in the vehicle body B, thereby fixing the inner tube 42 to the vehicle body B.

[0032] The elastic body 43 is made of rubber or elastomer and has a plurality of (four in this embodiment) hollow portions 43a that penetrate in the vertical direction. The hollow portions 43a are formed in a flat shape that is shorter in the radial direction than in the circumferential direction of the elastic body 43. However, the number of hollow portions 43a may be two to three, or five or more.

[0033] The vibration-isolating device 40 is interposed between the bracket body 30 and the vehicle body B, so that the bracket body 30 and the vehicle body B are elastically connected by the vibration-isolating device 40.

[0034] 3, the vibration isolation devices 40 are located near both ends of the rotation axis C of the vehicle electric accessory 20. This allows the vibrations generated from the vehicle electric accessory 20 when the rotating shaft member 21a rotates around the rotation axis C to be effectively absorbed.

[0035] 3.3.Soundproof Cover 50 As shown in FIG. 1, the soundproof cover 50 includes a first cover 51 attached to the bracket body 30, and a second cover 52 assembled to the first cover 51. When the first cover 51 is attached to the bracket body 30, the first cover 51 opens forward. A lock protrusion 51a that protrudes outward is formed on the outer surface of the first cover 51 at a position near the edge of the opening. A lock receiving portion 52a that elastically engages with the lock protrusion 51a is formed on the outer surface of the second cover 52 at a position corresponding to the lock protrusion 51a of the first cover 51. The lock receiving portion 52a is formed in a frame shape.

[0036] When the first cover 51 and the second cover 52 approach each other, the lock receiving portion 52a rides up on the lock protrusion 51a and undergoes elastic deformation. When the first cover 51 and the second cover 52 further approach each other, the lock receiving portion 52a rides up on the lock protrusion 51a and undergoes restoration deformation, and the lock receiving portion 52a engages with the lock protrusion 51a from behind. This assembles the first cover 51 and the second cover 52. However, the shapes of the lock protrusion 51a and the lock receiving portion 52a are not limited to those described above. Part 52aAny shape can be appropriately selected as long as the lock protrusions 51a and the lock receiving portions 52a can be engaged with each other. Furthermore, there is no particular limitation on the number of lock protrusions 51a and the lock receiving portions 52a. Furthermore, there is no particular limitation on the locations where the lock protrusions 51a and the lock receiving portions 52a are arranged, and the lock receiving portions 52a may be formed on the first cover 51 and the lock protrusions 51a may be formed on the second cover 52.

[0037] The first cover 51 includes a first main body cover 51b that covers the rear half of the main body 21 of the vehicle electric accessory 20, a first protrusion cover 51c that covers the rear half of the protrusion 22 of the vehicle electric accessory 20, and a first boss cover 51d that covers the boss 21c and boss base 21b of the vehicle electric accessory 20.

[0038] The second cover 52 includes a second main body cover 52b that covers the rear half of the main body 21 of the vehicle electric accessory 20, a second protrusion cover 52c that covers the rear half of the protrusion 22 of the vehicle electric accessory 20, and a second boss cover 52d that covers the boss 21c and boss base 21b of the vehicle electric accessory 20.

[0039] 1 and 2, the front surface of the third mounting portion 33 of the bracket body 30 is formed in a shape that follows the shape of the rear surface of the first main body portion cover 51b of the first cover 51. In other words, the curvature of the front surface of the third mounting portion 33 of the bracket body 30 is formed to be substantially the same as the curvature of the rear surface of the first main body portion cover 51b of the first cover 51. However, "substantially the same" includes cases where they are the same, and also includes cases where they can be recognized as being substantially the same even if they are not the same.

[0040] The front surface of the third mounting portion 33 of the bracket main body 30 and the rear surface of the first main body cover 51b of the first cover 51 are bonded with an adhesive material. In this way, the soundproof cover 50 is attached to the bracket main body 30. In other words, the soundproof cover 50 is attached to the first main surface 31a side (front side) of the bracket main body 30. As the adhesive material, a hard adhesive material or a soft adhesive material may be used. The adhesive material may be elastic, viscous, or viscoelastic. When the adhesive material is viscous or viscoelastic, transmission of vibration from the bracket main body 30 to the soundproof cover 50 can be further suppressed.

[0041] As shown in Fig. 2, a first engagement portion 53a that protrudes rearward is formed on the rear surface of the first cover 51 of the soundproof cover 50. Furthermore, a second engagement portion 53b that is drilled in the front-rear direction is formed on the third attachment portion 33 of the bracket main body 30 at a position corresponding to the first engagement portion 53a. The first engagement portion 53a engages with the second engagement portion 53b, thereby temporarily fixing the soundproof cover 50 to the bracket main body 30. This improves the efficiency of the work involved in bonding the soundproof cover 50 to the bracket main body 30.

[0042] With the first cover 51 and the second cover 52 assembled, the vehicle electric accessory 20 is covered by the soundproof cover 50 except for the protruding end (rear end) of the boss 21c. In other words, the protruding end of the boss 21c is not covered by the soundproof cover 50 and is exposed from the soundproof cover 50. In this manner, the soundproof cover 50 covers at least a portion of the vehicle electric accessory 20 on the first main surface 31a side of the bracket main body 30. The protruding end of the boss 21c abuts against the first main surface 31a of the first mounting portion 31 of the bracket main body 30 from the front. With the protruding end of the boss 21c abutting against the first main surface 31a of the first mounting portion 31, the bolt 36 is threaded into the female threaded hole 21d, thereby fixing the bracket main body 30 to the vehicle electric accessory 20.

[0043] 6, when the first cover 51 and the second cover 52 are assembled, the soundproof cover 50 includes a soundproof layer 54 made of a first foamed resin material and a protective layer 55 made of a second foamed resin material having a harder hardness than the first foamed resin material. The soundproof layer 54 is disposed facing the vehicle electric accessory 20. The protective layer 55 is disposed on the opposite side of the soundproof layer 54 from the vehicle electric accessory 20. However, the protective layer 55 may be omitted.

[0044] Suitable examples of the first foaming resin material include urethane foam, acrylic foam, silicone foam, styrene foam, foamed olefin (foamed PP, foamed PE), foamed PVC, foamed EVA, foamed PA, etc. The Asker C hardness of the first foaming resin material can be 1 to 60 degrees.

[0045] The hardness of the second foamed resin material is greater than that of the first foamed resin material. The Asker C hardness of the second foamed resin material can be 60 to 99 degrees. The second foamed resin material is different from the first foamed resin material. Examples of the second foamed resin material include urethane foam, acrylic foam, silicone foam, styrene foam, foamed olefin (foamed PP, foamed PE), foamed PVC, foamed EVA, and foamed PA. Note that even if urethane foam is applied to the soundproof layer 54 and the protective layer 55, the two urethane foams are different types. Furthermore, for example, foamed rubber can be used as the second foamed resin material. Examples of foamed rubber include foamed EPDM, foamed CR, foamed NBR / PVC, and foamed ACM.

[0046] The soundproof layer 54 may be configured to include a thermally conductive material (not shown). This can improve the heat dissipation properties of the soundproof layer 54. The thermally conductive material may extend from the vehicle electric accessory 20 side of the soundproof layer 54 toward the protective layer 55. For example, if the thermally conductive material is a thermally conductive filler, the thermally conductive filler is arranged in the soundproof layer 54 from the vehicle electric accessory 20 side toward the protective layer 55. Furthermore, the amount of thermally conductive material filled may vary depending on the position in the soundproof layer 54. Note that the amount of fill here refers to the amount of fill per unit area in the surface direction of the soundproof layer 54.

[0047] 6 and 7, a gap 56 is formed between the soundproof cover 50 and the vehicle electric accessory 20. In other words, the soundproof cover 50 covers the vehicle electric accessory 20 in a non-contact state. In this embodiment, the gap 56 is formed between all surfaces of the inner surface of the soundproof cover 50 and the outer surface of the vehicle electric accessory 20 that face each other.

[0048] As shown in FIG. 7 , among the outer surfaces of the vehicle electric accessory 20, the outer surface of the main body 21 is defined as a first outer surface 23a, and the outer surface of the protruding portion 22 is defined as a second outer surface 23b. Furthermore, a portion of the soundproof cover 50 facing the first outer surface 23a is defined as a first inner surface 57a, and a portion facing the second outer surface 23b is defined as a second inner surface 57b. A gap 56 between the first outer surface 23a and the first inner surface 57a is defined as a first gap 56a. Furthermore, a gap 56 between the second outer surface 23b and the second inner surface 57b is defined as a second gap 56b. In this embodiment, the first inner surface 57a and the second inner surface 57b are continuously disposed. In other words, the first inner surface 57a and the second inner surface 57b are in communication with each other.

[0049] 6, the joining area where the soundproof cover 50 and the bracket body 30 are joined is smaller than the opposing area where the soundproof cover 50 and the vehicle electric accessory 20 face each other. This will be explained in detail below.

[0050] As shown in Fig. 6, in this embodiment, at least the inner surface of the soundproof cover 50 faces the entire outer surface of the main body 21 of the vehicle electric accessory 20. Meanwhile, the joint area where the soundproof cover 50 and the bracket main body 30 are joined is set to be smaller than the entire circumference of the outer surface of the soundproof cover 50. The joint area where the soundproof cover 50 and the bracket main body 30 are joined can be set to any value within a range of 5% to 90% of the entire circumference of the outer surface of the soundproof cover 50. Furthermore, it is preferable that the joint area where the soundproof cover 50 and the bracket main body 30 are joined to be any value within a range of 10% to 50% of the entire circumference of the outer surface of the soundproof cover 50.

[0051] 4. An example of the manufacturing process of this embodiment Next, an example of a manufacturing process for the vibration and soundproofing device 10a according to this embodiment will be described with reference to Figures 1, 2, and 5. However, the manufacturing process for the vibration and soundproofing device 10a is not limited to the following description.

[0052] The bracket body 30 is formed into a predetermined shape by bending a metal plate material.

[0053] The first cover 51 and the second cover 52 are formed by molding a synthetic resin material.

[0054] An adhesive material is applied to the first cover 51 and the bracket body 30. The first engagement portion 53a of the first cover 51 is engaged with the second engagement portion 53b of the bracket body 30. This causes the first cover 51 and the bracket body 30 to be bonded together while being positioned. As a result, a part in which the bracket body 30 and the first cover 51 are assembled can be obtained (see FIG. 1).

[0055] 5, a portion of the vehicle electric accessory 20 is covered with the first cover 51. The vehicle electric accessory 20 is fixed to the bracket body 30 by threading the bolt 36 into the female threaded hole 21d of the boss 21c of the vehicle electric accessory 20.

[0056] 2, the locking projections 51a and the locking receivers 52a are engaged with each other to assemble the first cover 51 and the second cover 52. In this way, the vibration and soundproofing device 10a is completed.

[0057] 5. Effects of this form Next, the effects of this embodiment will be described. The vibration and soundproofing device 10a according to this embodiment includes a bracket body 30 that is attached to the vehicle electric accessory 20, a vibration-damping device 40 that is attached to the bracket body 30 and elastically connects the bracket body 30 to the vehicle body B, and a soundproofing cover 50 that is attached to the bracket body 30, the vibration-damping device 40, or the vehicle electric accessory 20 and covers the vehicle electric accessory 20 in a non-contact manner.

[0058] The fixing structure for the vehicle electric accessory 20 according to this embodiment uses the vibration and soundproofing device 10a to fix the vehicle electric accessory 20 to the vehicle body B of the vehicle.

[0059] According to this embodiment, vibrations generated by the operation of the vehicle electric accessory 20 are transmitted from the vehicle electric accessory 20 to the bracket body 30, and then damped by the vibration-damping device 40 attached to the bracket body 30. This prevents vibrations generated in the vehicle electric accessory 20 from being transmitted to the vehicle body B.

[0060] On the other hand, the sound generated by the operation of the vehicle electric accessory 20 is absorbed by the soundproof cover 50 that covers the vehicle electric accessory 20 .

[0061] Because the soundproof cover 50 and the vehicle electric accessory 20 are in a non-contact state, transmission of vibrations from the vehicle electric accessory 20 to the soundproof cover 50 is suppressed. This suppresses noise from being generated from the soundproof cover 50 due to vibrations transmitted from the vehicle electric accessory 20.

[0062] Furthermore, gaps 56 are formed between all surfaces of the inner surface of the soundproof cover 50 according to this embodiment and the outer surface of the vehicle electric accessory 20, where the surfaces face each other. This further reduces the transmission of vibrations from the vehicle electric accessory 20 to the soundproof cover 50.

[0063] Furthermore, the bracket body 30 according to this embodiment is attached to a portion of the vehicle electric accessory 20 that is not covered by the soundproof cover 50. The vehicle electric accessory 20 is relatively heavy. For this reason, it is desirable to attach it relatively firmly to the bracket body 30. According to this embodiment, since the soundproof cover 50 is not interposed between the bracket body 30 and the vehicle electric accessory 20, the bracket body 30 and the vehicle electric accessory 20 can be attached firmly.

[0064] Furthermore, the bracket body 30 according to this embodiment has a first main surface 31a that is attached to the vehicle electric accessory 20, and the soundproof cover 50 covers at least a portion of the vehicle electric accessory 20 on the first main surface 31a side of the bracket body 30. This allows the soundproof cover 50 to suppress transmission of at least a portion of the noise emitted from the vehicle electric accessory 20 to the outside.

[0065] The soundproof cover 50 according to this embodiment is attached to the bracket body 30 by an adhesive material, which allows the soundproof cover 50 and the vehicle electric accessory 20 to be kept out of contact with each other.

[0066] Vibrations generated by the operation of the vehicle electric accessory 20 may be transmitted to the bracket body 30 to which the vehicle electric accessory 20 is attached, and then to the soundproof cover 50 attached to the bracket body 30. Vibrations generated by the operation of the vehicle electric accessory 20 may also be transmitted directly to the soundproof cover 50 that covers the vehicle electric accessory 20. In this embodiment, the joint area where the soundproof cover 50 and the bracket body 30 are joined is smaller than the opposing area where the soundproof cover 50 and the vehicle electric accessory 20 face each other. Therefore, the amount of vibration transmitted from the vehicle electric accessory 20 to the soundproof cover 50 via the bracket body 30 is less than the amount of vibration transmitted directly from the vehicle electric accessory 20 to the soundproof cover 50. Furthermore, in this embodiment, the vehicle electric accessory 20 is not in contact with the soundproof cover 50, so direct transmission of vibration from the vehicle electric accessory 20 to the soundproof cover 50 is suppressed. As a result, the vibration transmitted from the vehicle electric accessory 20 to the soundproof cover 50 can be further reduced.

[0067] The bracket main body 30 according to this embodiment includes a first mounting portion 31 having a first main surface 31a to be mounted on the vehicle electric accessory 20 and arranged so that the first main surface 31a faces the vehicle electric accessory 20, and a second mounting portion 32 formed integrally with the first mounting portion 31 and mounted on the vehicle body B, the second mounting portion 32 being arranged on the first main surface 31a side of the first mounting portion 31. Since the vehicle electric accessory 20 is relatively heavy, by arranging the second mounting portion 32 on the first main surface 31a side, the vehicle electric accessory 20 can be firmly supported.

[0068] The vehicle electric accessory 20 according to this embodiment includes a rotating shaft member 21a, and the bracket body 30 extends in the direction of the rotation axis C of the rotating shaft member 21a and includes a first mounting portion 31 having a first main surface 31a to be mounted to the vehicle electric accessory 20 and arranged so that the first main surface 31a faces the vehicle electric accessory 20, and a plurality of second mounting portions 32 formed integrally with the first mounting portion 31 and mounted to the vehicle body B, and at least one of the plurality of second mounting portions 32 is arranged on one end side of the rotating shaft member 21a in the direction of the rotation axis C with respect to the vehicle electric accessory 20. This can improve the vibration isolation performance of the vibration and soundproofing device 10a.

[0069] Furthermore, according to this embodiment, at least one other of the plurality of second mounting portions 32 is disposed on the other end side of the rotating shaft member 21a in the direction of the rotation axis C with respect to the vehicle electric accessory 20. This further improves the vibration isolation performance of the vibration and soundproofing device 10a.

[0070] The soundproof cover 50 according to this embodiment includes a soundproof layer 54 formed of a first foamed resin material, which can further improve the vibration-proofing and soundproofing device 10a's vibration-proofing performance.

[0071] The soundproof cover 50 according to this embodiment includes a soundproof layer 54 disposed opposite the vehicle electric accessory 20, and a protective layer 55 formed of a second foamed resin material having a harder hardness than the first foamed resin material and disposed on the side of the soundproof layer 54 opposite the vehicle electric accessory 20. This protects the soundproof layer 54 and allows the shape of the soundproof layer 54 to be maintained.

[0072] The vibration and soundproofing device 10a (bracket with vibration and soundproofing functions) of this embodiment comprises a bracket body 30 having a first main surface 31a to which a vehicle electric accessory 20 is attached, a soundproofing cover 50 attached to the bracket body 30 and covering at least a portion of the vehicle electric accessory 20 on the first main surface 31a side of the bracket body 30, and a vibration-proofing device 40 attached to the bracket body 30 and elastically connecting the bracket body 30 to the vehicle body B.

[0073] According to this embodiment, the bracket body 30, the vibration-damping device 40, and the soundproof cover 50 can be handled as a single part, thereby reducing the number of parts compared to when the bracket body 30, the vibration-damping device 40, and the soundproof cover 50 are handled as separate parts.

[0074] (Embodiment 2) Next, a vibration and soundproofing device 10b according to a second embodiment will be described with reference to Fig. 8. In this embodiment, a protruding wall 58 that protrudes from the soundproof layer 54 toward the main body 21 is formed between the first inner surface 57a and the second inner surface 57b of the soundproof cover 50. The tip of the protruding wall 58 abuts against the outer surface of the main body 21 of the vehicle electric accessory 20. As a result, the first inner surface 57a and the second inner surface 57b of the soundproof cover 50 are discontinuously arranged by the protruding wall 58.

[0075] Note that, among the symbols used in the second and subsequent embodiments, the same symbols as those used in the previous embodiments represent the same components, etc. as those in the previous embodiments, unless otherwise specified.

[0076] (Embodiment 3) Next, a vibration and soundproofing device 10c according to a third embodiment will be described with reference to Fig. 9. In this embodiment, the size of the first gap 56a is different from the size of the second gap 56b. In this embodiment, the size of the first gap 56a is smaller than the size of the second gap 56b. However, the size of the first gap 56a may be larger than the size of the second gap 56b.

[0077] However, the thickness of the soundproof cover 50 may be different between the area where the first gap 56a is formed and the area where the second gap 56b is formed.

[0078] (Embodiment 4) Next, a vibration and soundproofing device 10d according to a fourth embodiment will be described with reference to Fig. 10. In this embodiment, the first inner surface 57a and the second inner surface 57b of the soundproofing cover 50 are discontinuously arranged by a protruding wall 58. In this embodiment, the size of the first gap 56a is different from the size of the second gap 56b.

[0079] (Embodiment 5) Next, a vibration and soundproofing device 10e according to a fifth embodiment will be described with reference to Fig. 11. In this embodiment, the first main surface 31a and the second main surface 32a form surfaces on the same side of the bracket body 30, and the first main surface 31a and the second main surface 32a are connected at an angle.

[0080] (Embodiment 6) Next, a vibration and soundproofing device 10f according to a sixth embodiment will be described with reference to Fig. 12. In this embodiment, the first main surface 31a and the second main surface 32a form surfaces on the same side of the bracket body 30, and the first main surface 31a and the second main surface 32a form a smoothly continuous surface.

[0081] (Embodiment 7) Next, a vibration and soundproofing device 10g according to embodiment 7 will be described with reference to Fig. 13. In this embodiment, the first main surface 31a and the second main surface 32a form opposite surfaces of the bracket body 30, and the first main surface 31a and the second back surface 32b form a smoothly continuous surface.

[0082] (Embodiment 8) Next, a vibration- and sound-proof device 10h according to an eighth embodiment will be described with reference to FIG. 14. In this embodiment, the soundproof cover 50 is attached to the third attachment portion 33 of the bracket body 30 via a vibration-isolating member 61. The vibration-isolating member 61 is preferably formed from a material with excellent vibration-isolating properties, such as a foamed resin. Examples of foamed resins include urethane foam, acrylic foam, silicone foam, styrene foam, foamed olefin (foamed PP, foamed PE), foamed PVC, foamed EVA, and foamed PA. The vibration-isolating member 61 may be formed from a non-foamed resin with vibration-isolating properties, or may be formed from a metal. Examples of non-foamed resins include polyamide resin, olefin resin, styrene resin, urethane resin, silicone resin, acrylic resin, polyvinyl chloride resin, polyethylene resin, polyethylene terephthalate resin, polycarbonate resin, polypropylene resin, ABS resin, EVA resin, and carbon fiber plastic (FRP, CFRP). Examples of metals include iron, aluminum, stainless steel, copper, and alloys thereof.

[0083] According to this embodiment, vibrations generated in the vehicle electric accessory 20 and transmitted to the bracket main body 30 can be prevented from being transmitted from the bracket main body 30 to the soundproof cover 50. This prevents the soundproof cover 50 from generating noise due to the transmitted vibrations.

[0084] However, the bracket body 30 and the soundproof cover 50 may be connected by the above-mentioned vibration-isolating device 40. For example, by configuring the bracket body 30 to be connected to the outer tube 41 of the vibration-isolating device 40 and the soundproof cover 50 to be connected to the inner tube 42 of the vibration-isolating device 40, it is possible to suppress transmission of vibrations from the bracket body 30 to the soundproof cover 50.

[0085] (Embodiment 9) Next, a vibration and soundproofing device 10i according to a ninth embodiment will be described with reference to Fig. 15. In this embodiment, the soundproofing cover 50 is attached to the vehicle electric accessory 20 via a vibration-isolating member 62. This makes it possible to further suppress the transmission of vibrations from the vehicle electric accessory 20 to the soundproofing cover 50.

[0086] (Embodiment 10) Next, a vibration and soundproofing device 10j according to a tenth embodiment will be described with reference to Fig. 16 to Fig. 18. In this embodiment, as shown in Fig. 16, a soundproofing cover 50 is connected to the inner tube 42 of the vibration damping device 40 via a connecting member 59. The connecting member 59 is formed to protrude from the soundproofing cover 50 toward the inner tube 42 of the vibration damping device 40. The connecting member 59 is attached to the inner tube 42 by a known method such as adhesive bonding, heat welding, or screw fastening.

[0087] 17 and 18 , in this embodiment, a gap 56c is formed between the third mounting portion 33 of the bracket main body 30 and the soundproof cover 50. In other words, the third mounting portion 33 of the bracket main body 30 and the soundproof cover 50 are not in contact with each other. This prevents vibrations from being transmitted from the third mounting portion 33 of the bracket main body 30 to the soundproof cover 50.

[0088] Vibrations generated in the vehicle electric accessory 20 are transmitted to the bracket body 30. The vibrations transmitted to the bracket body 30 are then transmitted from the bracket body 30 to the outer tube 41 of the vibration-damping device 40 and absorbed by the elastic body 43. As a result, the vibrations transmitted to the inner tube 42 of the vibration-damping device 40 are attenuated. Since the soundproof cover 50 is attached to this inner tube 42, the vibrations generated in the vehicle electric accessory 20 can be prevented from being transmitted to the soundproof cover 50.

[0089] The present invention is not limited to the above-described embodiments, and can be applied to various embodiments within the scope of the present invention. [Explanation of symbols]
