[0027] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0028] It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of clear narration, and are not used to limit the scope for the implementation of the present invention. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope for the implementation of the present invention.

[0029] Please refer to Figures 1 to 9 , this embodiment provides a wire harness installation bracket, including a bracket body 1 and a vibration damping bushing 2. The bracket body 1 is used to restrain the wire harness, and the bracket body 1 has a connection installation position for connecting with an installation object.

[0030] The vibration damping bushing 2 is arranged at the connection and installation position. The bracket body 1 acts on the installation object through the vibration damping bushing 2. When the bracket body 1 is installed on the installation object, the vibration damping bushing 2 is supported between the bracket body 1 and the installation object. The vibration damping bushing 2 is equivalent to a damper. When vibrations of installation objects such as an automobile body are transmitted to the harness installation, the vibration damping bushing 2 plays a role in damping the bracket body 1, thereby reducing the vibrations of the harness installation bracket and the harness installed on the harness installation bracket.

[0031] In this embodiment, the bracket body 1 is a box-shaped body with a hollow cavity inside. The end of the box-shaped body has an opening 11, and the opening 11 and the hollow cavity inside the bracket body 1 form an installation channel. The harness is threaded through the installation channel. The bracket body 1 restricts the harness, which helps to avoid the harness being messy, and the bracket body 1 also protects the harness arranged therein.

[0032] In this embodiment, the bracket body 1 also has an abutting position for contacting an external object. The harness installation bracket contacts the external object at the abutting position. A buffer pad 3 is arranged on the abutting position, and the bracket body 1 contacts the external object through the buffer pad 3. The buffer pad 3 plays a role in supporting and buffering the bracket body 1. When the bracket body 1 is forced to vibrate, the buffer pad 3 can prevent the bracket body 1 from directly contacting the external object, thereby reducing the probability of abnormal noise occurring. In this embodiment, the bracket body 1 is provided with a through hole at the abutting position. As Figure 9 shown, the outer periphery of the buffer pad 3 is provided with an installation groove 31, and the buffer pad 3 is clamped in the through hole through the installation groove 31. The installation groove 31 positions the buffer pad 3 and reduces the probability of the buffer pad 3 accidentally falling out of the through hole. The abutting position is provided with a notch around the through hole, and the notch communicates with the through hole and the peripheral edge of the abutting position. The buffer pad 3 can be snapped into the through hole through the notch, which is convenient for the installation of the buffer pad 3.

[0033] As Figures 3 to 8 shown, in this embodiment, the vibration damping bushing 2 includes a bushing body 20 and a protective sleeve 23. The bushing body 20 has an installation hole penetrating through the bushing body 20, and the protective sleeve 23 is threaded through the installation hole. The harness installation bracket is usually installed on the installation object through connecting members such as bolts, and the installation hole is for the connecting member to pass through. The bushing body 20 is usually made of materials such as rubber, and has poor wear resistance, while the protective sleeve 23 can be processed with materials such as stainless steel and has better wear resistance. The connecting member is threaded through the protective sleeve 23. Compared with the connecting member being directly threaded through the bushing body 20, it can prevent the connecting member from directly contacting the bushing body 20, thereby helping to improve the service life of the vibration damping bushing 2.

[0034] As Figure 3 、 Figure 5As shown, in a specific optional embodiment, the edge of the end of the protective sleeve 23 away from the installation object has a flange 24 extending radially outward along the vibration damping bushing 2, and the flange 24 covers the bushing body 20. The head end of the installation member usually has a limiting portion, such as the head of a bolt. When the vibration damping bushing 2 is installed through the installation member, the limiting portion of the installation member also acts on the vibration damping bushing 2. The flange 24 covers the bushing body 20, which can prevent the limiting portion of the installation member from directly contacting the bushing body 20, thereby facilitating the improvement of the service life of the vibration damping bushing 2.

[0035] Such as Figure 6 And Figure 8 As shown, in another specific optional embodiment, flanges 24 extending radially outward along the vibration damping bushing 2 are respectively provided on the edges of both ends of the protective sleeve 23, and the two flanges 24 respectively block the two ends of the bushing body 20. The two flanges 24 can limit the vibration damping bushing 2 and constrain the bushing body 20 on the protective sleeve 23, which is beneficial to preventing the bushing body 20 from accidentally falling off the protective sleeve 23.

[0036] Such as Figure 3 , Figure 4 As shown, in a specific optional embodiment, a plurality of protrusions are provided on the end face of the bushing body 20. The protrusions protrude from the end face, and the size of the protrusions is small, so the stiffness is weaker than that of the bushing body 20, making the vibration damping bushing 2 have multi-stage vibration damping. When the vibration amplitude is small, the vibration of the support body 1 is mainly damped by the deformation of the protrusions. Since the stiffness of the protrusions is relatively low compared to the bushing body 20, the protrusions can also generate large deformations at a low vibration amplitude, thereby damping and absorbing energy, which is beneficial to avoiding directly transmitting the vibration to the support body 1 due to the too high stiffness of the vibration damping bushing 2. When the vibration amplitude is large, the vibration of the support body 1 is mainly damped by the deformation of the bushing body 20. When the vibration amplitude is large, the deformation of the protrusions reaches the limit, and the bushing body 20 continues to deform to damp and absorb energy, playing a role in damping the vibration of the support body 1. At the same time, by adjusting the shape and number of the protrusions, the overall stiffness of the protrusions can be adjusted, thereby adjusting the vibration damping range of the vibration damping bushing 2 to meet different vibration damping requirements.

[0037] Specifically, in this specific embodiment, the protrusions are damping teeth 22. Damping teeth 22 are provided on the end faces of both ends of the bushing body 20. The tops of the damping teeth 22 extend radially along the vibration damping bushing 2, and the damping teeth 22 are arranged in sequence and evenly around the axis of the whole damping set. The damping teeth 22 have a simple structure and are easy to process, which is beneficial to reducing the product cost.

[0038] The vibration damping bushing 2 is usually fixed on the support body 1 before the wire harness mounting bracket is mounted on the installation object, so as to facilitate the installation of the wire harness mounting bracket. Such as Figures 3 to 8As shown, in this embodiment, a clamping groove 21 is provided on the outer periphery of the bushing body 20. The clamping groove 21 surrounds the bushing body 20 in a circumferential direction for one week. A clamping hole penetrating through the connection and installation position is provided at the connection and installation position. The damping bushing 2 is clamped on the clamping hole at the connection and installation position through the clamping groove 21. In this embodiment, the part of the bracket body 1 at the connection and installation position is generally plate-shaped. After the damping bushing 2 is installed in the clamping hole, the part of the bracket body 1 at the connection and installation position is inserted into the clamping groove 21. The clamping groove 21 limits the damping bushing 2 to prevent the damping bushing 2 from falling off the bracket body 1.

[0039] An installation notch 12 for the damping bushing 2 to pass through is further provided at the connection and installation position. The installation notch 12 communicates with the clamping hole and the area outside the outer periphery of the connection and installation position. The damping bushing 2 can be directly clamped into the clamping hole through the installation notch 12 from the area outside the outer periphery of the installation position, without being clamped into the opening 11 at both ends of the clamping hole, which is convenient for the installation of the damping bushing 2.

[0040] In summary, for the wire harness installation bracket of this embodiment, when the bracket body 1 is installed on the installation object, the bracket body 1 acts on the installation object through the damping bushing 2, and the damping bushing 2 is supported between the bracket body 1 and the installation object. Therefore, when the vibration of the installation object such as an automobile body is transmitted to the wire harness installation, the damping bushing 2 is equivalent to a damper, which plays a role in damping the bracket body 1, thereby reducing the vibration of the wire harness installation bracket and the wire harness installed on the wire harness installation bracket.

[0041] The above embodiments only illustratively explain the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
