(57) [Summary] [Purpose] To prevent the transmission of vibrations from wiring and piping from the engine and various auxiliary equipment, and to reduce indoor noise. [Structure] An auxiliary member is installed between the floor side members extending in the longitudinal direction of the vehicle, separated from the floor panel via a vibration-proof mount, and the wiring from the engine and various auxiliary equipment is installed approximately in the middle of the auxiliary member. Route and secure piping.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea allows the wiring and piping from the vehicle's engine and various auxiliary equipment to be routed to the underside of the floor. Regarding the mounting structure for wiring.

0002

[Conventional technology]

Conventionally, wiring W and piping T from this type of engine E or various auxiliary equipment were arranged. Connect the wiring W and wiring directly to the floor panel 1 or dash panel in order to Brackets 2a, 2b, etc. that match the pipe T are installed, and this bracket Attach to the mounting plate 2 via the anti-vibration mount 3 using clamp members 4a, 4b, etc. The cables had been fixed.

0003

[Problem that the idea aims to solve]

However, in this conventional wiring fixing structure, the wiring W and piping T are mounted on brackets. 2 through the anti-vibration mount 3, but the brackets 2a, 2b... Since it is configured to be directly attached to the lower panel 1, vibrations from engine E, for example, The vibration is transmitted to the line W and the piping T, and the vibration isolating mount 3 and brackets 2a, 2b... The problem is that the sound resonates and is further amplified by the floor panel 1, causing indoor muffled sound. There was a point. In addition, each of these brackets 2a, 2b... should be provided with vibration damping measures. However, there were problems such as being uneconomical in terms of cost and space.

0004 This invention was made to solve the above conventional problems, and it This prevents the transmission of vibration from the wiring and piping from the machine, reducing indoor noise. The purpose is to provide a wiring/piping installation structure for vehicles that can be installed easily.

[0005]

[Means to solve the problem]

In order to solve the above technical problem, this invention has developed a floor size that extends in the longitudinal direction of the vehicle. An auxiliary member is installed between the domain members via an anti-vibration mount, and approximately halfway between the auxiliary members is installed. Vehicles with a structure in which wiring and piping from the engine and various auxiliary equipment are routed and fixed. This depends on the wiring and piping installation structure.

[0006]

[Effect]

Vibrations transmitted through the wiring and piping from the engine and various auxiliary equipment are The spring effect of the piping mounting member itself and the rubber mount that fixed the wires and piping It functions to absorb by synergistic effect with

[0007]

【Example】

Next, one embodiment of the present invention will be explained according to the drawings. Figure 1 shows the floor of the vehicle body. This is a cross-sectional view of the panel 11 side, and the left and right sides of the floor panel 11 are A rigid floor side member 12 having a substantially U-shaped cross section extending in the direction is attached. The wiring from the engine E and various auxiliary equipment is connected between the left and right floor side members 12. The pipe mounting member 13 (also referred to as auxiliary member) for arranging the W and pipe T is multiple. There are several installed.

[0008] This piping mounting member 13 is made of thin steel plate or synthetic resin material. The piping attachment member 13 is formed, for example, into a substantially U-shaped cross section, and its longitudinal A curved portion 14 that curves upward is formed approximately in the center of the direction, and a curved portion 14 that curves upward is formed on both sides of the curved portion 14. A horizontal part 15 is formed, and the end of this horizontal part 15 is formed into a flat shape to connect to the mounting part 1. 6 is formed. The piping mounting member 3 formed in this way has low rigidity. The curved part 14 formed in the center has a bending ability, and the entire part produces a spring effect. It is set up to perform.

[0009] The piping mounting member 13 formed in this way is connected via the left and right mounting portions 16. Rubber mounts for vibration absorption are installed on the mounting parts 12a of the left and right floor side members 12. It is installed with a mounting bolt 18 with a vibration-proof mount 17 interposed therebetween. ing. The piping installation member 13 installed in this way is located from the floor panel 11. They are suspended horizontally at predetermined intervals.

0010 The horizontal part 15 of the pipe mounting member 13 suspended horizontally in this way has the wiring W and the The pipe T is equipped with mounting brackets 19a, 19b and a mounting protector made of synthetic resin or the like. The cables are fixedly wired via the connectors 20a and 20b.

[0011] As mentioned above, piping is installed between the floor side members 12 extending in the front and rear direction of the vehicle. The mounting member 13 is separated from the floor panel 11 via the rubber mounting 17. The engine and various auxiliary equipment are connected to the horizontal part 5 of this piping installation member 13. The wiring W and piping W are centrally routed and fixed. Therefore, engine E The vibrations transmitted through the wiring W and piping T from various auxiliary equipment are The spring effect of the piping mounting member 13 itself and the rubber mount that fixed the piping T It is absorbed by the synergistic effect with vibration damping 17, and can improve vibration isolation. , since it was installed on the piping installation member 13 that is spaced apart from the floor panel 11, the floor It is possible to cut off resonance in panel 11 and eliminate part of the cause of muffled sound. can be done.

0012 In the above embodiment, the cross-sectional shape of the pipe mounting member 13 is approximately U-shaped. Although the example is not limited to this, for example, even if the cross section is approximately L-shaped, good.

[0013]

[Effect of the idea]

Since the present invention is constructed as described above, the engine and various auxiliary equipment Vibration transmitted through wiring and piping can be caused by Absorbed by the synergistic effect of the spring effect of the piping mounting member itself and the rubber mounting. In addition to improving vibration isolation, piping that is separated from the floor panel Since it is attached to the mounting member, it is possible to eliminate resonance from the floor panel. Part of the cause of the muffled sound can be eliminated.
