Description

Technical Field

[0001] The utility model belongs to the technical field of automobile wiring harness protection devices, and in particular relates to a wiring harness protection device for new energy vehicles. Background Art

[0002] In new energy vehicles, the high-voltage system is one of the core parts. As the medium that connects the various components in the high-voltage system, its role is very important. Because the high-voltage wire harness has the characteristics of high voltage, large current, heat resistance and durability, and the high-voltage wire harness works in a vibration environment for a long time, the wire harness is prone to deformation and fatigue, which affects the normal operation of the wire harness. Therefore, it is particularly important to position it for a long time and provide corresponding protection.

[0003] Existing technologies usually use rolling strips or clips to position the wiring harness, and some use protective shells to protect the wiring harness. In order to facilitate maintenance, this device is generally spliced and fixed by buckles. When the car is driving in a bumpy state with relatively large vibration, the connection between the protective shells may become loose, affecting the protection effect. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a wiring harness protection device for new energy vehicles. A clamping ring is used to align with the position of the groove and press it. The two ends of the clamping ring will respectively enter the two clamping grooves on the surface of the first protective shell. Under the action of the clamping ring's own elasticity, the clamping ring passes over the block and then rebounds to its original position. The setting of the block prevents the clamping ring from loosening, thereby strengthening the fixing effect of the first protective shell and the second protective shell, thereby preventing it from loosening easily in an environment with large bumps and vibrations.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a new energy vehicle wiring harness protection device, comprising a first protective shell, a second protective shell and a retaining ring, a mounting seat being provided on the surface of the first protective shell, a rectangular groove being provided inside the second protective shell, a plurality of springs being fixedly connected to the inside of the rectangular groove, and a plurality of springs being fixedly connected to a rubber pressure block at one end away from the rectangular groove, a plurality of fixed sockets being fixedly connected to the surface of the first protective shell, a plurality of fixed plug rods being fixedly connected to the surface of the second protective shell, a buffer pad being fixedly connected to the inside of the first protective shell, a card slot being provided on the surface of the first protective shell, a block being fixedly connected to the inside of the card slot, and a groove being provided on the surface of the second protective shell.

[0006] Furthermore, the positions of the groove and the card slot correspond to each other.

[0007] Furthermore, the opposing surfaces of the first protective shell and the second protective shell are respectively provided with rubber buffer strips.

[0008] Compared with the prior art, the beneficial effects of the present invention are:

[0009] 1. Under the action of spring rebound, the rubber pressure block is driven to reset and squeeze the wiring harness, thereby strengthening the fixing effect of the wiring harness and preventing it from loosening. At the same time, in order to strengthen the fixing effect between the first protective shell and the second protective shell, a snap ring is used to align the position of the groove and press. The two ends of the snap ring will respectively enter the two grooves on the surface of the first protective shell. Under the action of the snap ring's own elasticity, it passes over the block and then rebounds to reset. The setting of the block prevents the snap ring from loosening, thereby strengthening the fixing effect between the first protective shell and the second protective shell.

[0010] 2. When fixing the second protective shell, align the fixing rod with the corresponding fixing socket, and then close the second protective shell. At this time, the fixing rod will be inserted into the corresponding fixing socket to fix it. The buffer strip can play a buffering role between the first protective shell and the second protective shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] See attached Figure 1-3 As shown, a wiring harness protection device for a new energy vehicle includes a first protective shell 1, a second protective shell 2 and a snap ring 12. A mounting seat 6 is provided on the surface of the first protective shell 1, a rectangular groove 7 is provided inside the second protective shell 2, a plurality of springs 8 are fixedly connected to the inside of the rectangular groove 7, and a rubber pressure block 9 is fixedly connected to one end of the plurality of springs 8 away from the rectangular groove 7. A plurality of fixed sockets 3 are fixedly connected to the surface of the first protective shell 1, a plurality of fixed insertion rods 4 are fixedly connected to the surface of the second protective shell 2, a buffer pad 5 is fixedly connected to the inside of the first protective shell 1, a card slot 10 is provided on the surface of the first protective shell 1, a block 11 is fixedly connected to the inside of the card slot 10, and a groove is provided on the surface of the second protective shell 2.

[0018] The groove corresponds to the position of the card slot 10 .

[0019] The opposite surfaces of the first protective shell 1 and the second protective shell 2 are respectively provided with rubber buffer strips.

[0020] Working principle: Through the setting of the mounting seat 6, it is convenient to install the first protective shell 1 inside the new energy vehicle body, and then place the wiring harness on the buffer pad 5 inside the first protective shell 1. When fixing the second protective shell 2, align the fixing rod 4 with the corresponding fixing socket 3, and then close the second protective shell 2. At this time, the fixing rod 4 will be inserted into the corresponding fixing socket 3 to fix it. At the same time, the rubber pressure block 9 will contact the wiring harness on the buffer pad 5. The rubber pressure block 9 is squeezed and drives the spring 8 to contract. Under the action of the spring 8 rebound, the rubber pressure block 9 is reset to squeeze the wiring harness, thereby strengthening the fixing effect of the wiring harness. To prevent loosening, and at the same time, in order to strengthen the fixing effect between the first protective shell 1 and the second protective shell 2, a snap ring 12 is used to align with the position of the groove and press. The two ends of the snap ring 12 will respectively enter the two grooves 10 on the surface of the first protective shell 1. Under the action of its own elasticity, the snap ring 12 passes over the stopper 11 and then rebounds to its original position. The setting of the stopper 11 prevents the snap ring 12 from loosening, thereby strengthening the fixing effect of the first protective shell 1 and the second protective shell 2, thereby preventing them from loosening easily in an environment with large bumps and vibrations. The setting of the buffer strip can play a buffering role between the first protective shell 1 and the second protective shell 2.
