Detailed Description
Hereinafter, the high-voltage cable protective member 100 according to the present embodiment will be described with reference to the drawings.
Fig. 1 is a plan view showing a state in which the high-voltage cable protection member 100 according to the present embodiment is used in an electric vehicle 200, that is, a state in which the high-voltage cable 150 is held by the high-voltage cable protection member 100 in the electric vehicle 200. In the following drawings, the direction of the arrow OUT indicates the outside of the electric vehicle 200; the direction of the arrow UP indicates the upper side of the electric vehicle 200.
As shown in fig. 1, relevant electrical devices (hereinafter, simply referred to as relevant devices) such as an inverter 170, a high-voltage battery (not shown), and a motor (not shown) are mounted on a vehicle body 210 of an electric vehicle 200. The related devices are connected to each other by a high voltage cable 150. Each of the related devices is connected to the high voltage cable 150 through a connector 151. The high-voltage cable 150 is held by the high-voltage cable protective member 100 fixed to the vehicle body 210.
The high-voltage cable protection member 100 includes a protection member body (main body portion) 10, an external opening 30, a holding portion 50, and a guide portion 70. The high-voltage cable protective member 100 is made of, for example, an elastically deformable synthetic resin.
The protective member body 10 is a part constituting a base of the high-voltage cable protective member 100, and has an internal space. An external opening 30 is formed in the sheathing member body 10 to communicate the internal space of the sheathing member body 10 with the outside. The high-voltage cable 150 can be inserted into the internal space from the outside through the external opening 30. The high voltage cable 150 held by the high voltage cable protective member 100 can escape to the outside through the external opening 30 when the electric vehicle 200 collides.
The holding portion 50 is located in the inner space of the protective member main body 10 for accommodating (holding) the high-voltage cable 150 inserted from the external opening 30.
The guide part 70 is provided between the holding part 50 and the outer opening 30 for guiding the high voltage cable 150 moving between the outer opening 30 and the holding part 50.
Fig. 2 is a sectional view taken along line a-a in fig. 1. As shown in fig. 2, the protective member body 10 includes a first wall portion 11, a second wall portion 12, a third wall portion 13, a 4 th wall portion 14, and a 5 th wall portion 15. In fig. 2, the first wall portion 11 and the second wall portion 12 are opposed in the horizontal direction (i.e., face-to-face); the third wall portion 13 and the second wall portion 12 are also opposed in the horizontal direction (i.e., face-to-face). In addition, the 4 th wall portion 14 and the 5 th wall portion 15 face each other in the vertical direction. The external opening 30 is formed between the first end 111 of the first wall portion 11 and the second end 131 of the third wall portion 13. In other words, the external opening 30 is configured to partition the first wall portion 11 and the third wall portion 13 on both sides thereof, and one end edge thereof is positioned at the first end 111 of the first wall portion; the other end edge thereof is located on the second end 131 of the third wall portion 13. The interval between the first end portion 111 and the second end portion 131 is an opening width of the external opening 30, which is set larger than the outer diameter (diameter) of the high voltage cable 150. The high-voltage cable protective member 100 is mounted on the vehicle body 210 such that the second wall portion 12 abuts against the mounting surface 211 of the vehicle body 210, i.e., the second wall portion 12 is mounted on the mounting surface 211 of the vehicle body 210.
The internal space of the protective member body 10 serves as the holding portion 50, that is, the holding portion 50 is constituted by the first wall portion 11, the second wall portion 12, and the 4 th wall portion 14. The holding portion 50 holds therein the high-voltage cable 150 inserted from the external opening 30.
Further, a holding portion inlet 53 is formed between the first end portion 111 and the second wall portion 12. The holding portion inlet 53 has a locking portion 55 having a triangular cross section, and is configured to have an opening width smaller than the outer diameter (diameter) of the high-voltage cable 150. By elastically deforming the first wall portion 11 and moving the first end portion 111 (see fig. 4), the holding portion entrance 53 can be widened to allow the high-voltage cable 150 to pass therethrough, and the high-voltage cable 150 can be fitted into the holding portion 50. Normally, the high voltage cable 150 can be caught inside the holding part 50 by the catching part 55. When the high-voltage cable 150 is pressed against the first end 111 by an external force (e.g., a collision), the holding portion inlet 53 is widened, and the high-voltage cable 150 held in the holding portion 50 is pulled out from the holding portion 50.
The guide 70 is disposed in the inner space of the sheathing member body 10. That is, the guide portion 70 is configured such that one end thereof is connected to the second wall portion 12 in the vicinity of the holding portion 50; the other end thereof is connected to the other end edge of the external opening 30 (i.e., the second end 131 of the third wall portion 13). Specifically, the guide portion 70 extends from the second end portion 131 toward the second wall portion 12 and is inclined in a direction approaching the holding portion entrance 53. In fig. 2, the guide portion 70 is inclined upward from the second end 131 toward the second wall portion 12. If the fitting direction of the high-voltage cable 150 fitted from the external opening 30 is D, the guide portion 70 has a guide surface intersecting the fitting direction D, and therefore, the guide portion 70 guides the high-voltage cable 150 in a direction intersecting the fitting direction D (i.e., an upper direction). Thereby, the guide portion 70 can guide the high-voltage cable protective member 100 inserted from the external opening 30 to the holding portion 50. In addition, when the high voltage cable 150 receives an external force, the guide part 70 can guide the high voltage cable 150 separated from the holding part 50 to the external opening 30.
Fig. 3 is a plan view showing a state in which the high-voltage cable 150 is pulled out from the high-voltage cable protective member 100 when the electric vehicle 200 collides. As shown in fig. 3, the inverter 170 changes its position from the position shown by the broken line (the position in fig. 1) to the position shown by the solid line due to the impact applied to the electric vehicle 200. Due to the position change of the inverter 170, the high voltage cable 150 is subjected to an external force, so that the high voltage cable 150 is released from the high voltage cable protective member 100.
Fig. 4 is a cross-sectional view taken along line B-B in fig. 3. Fig. 4 shows a state where the high voltage cable 150 is pulled out from the high voltage cable protective member 100. As shown in fig. 4, when the electric vehicle 200 collides, the high-voltage cable 150(150A) held by the holding portion 50 receives an external force, and the high-voltage cable 150(150A) presses the first wall portion 11 to move the first end portion 111, so that the holding portion inlet 53 is widened.
When the holding portion entrance 53 is widened and the high-voltage cable 150 can pass through, the high-voltage cable 150(150B) held by the holding portion 50 is separated from the holding portion 50 through the holding portion entrance 53. Thereafter, the high-voltage cable 150(150B) separated from the holding portion 50 comes into contact with the guide portion 70, and is guided to the outer opening 30 by the guide portion 70.
Finally, the high-voltage cable 150(150C) guided to the external opening 30 by the guide 70 escapes from the high-voltage cable protective member 100 to the outside via the external opening 30.
As shown in fig. 3, the high-voltage cable 150 that has come out of the high-voltage cable protective member 100 is not fixed to the vehicle body 210. Therefore, even if the position of the relevant device such as the inverter 170 changes at the time of a collision of the electric vehicle 200, the problem of the insufficient length (insufficient length margin) of the moving amount of the high-voltage cable 150 with respect to the relevant device can be avoided.
That is, when the electric vehicle 200 collides, the high-voltage cable 150 held inside the high-voltage cable protective member 100 is guided from the holding portion 50 to the external opening 30 by the guide portion 70 due to an external force, and is pulled out to the outside of the high-voltage cable protective member 100 through the external opening 30. Therefore, the problem of insufficient length margin due to the movement of the relevant equipment can be avoided, and the occurrence of disconnection of the high-voltage cable 150 or the falling of the connector of the high-voltage cable 150 from the relevant equipment can be effectively prevented.
The present invention is not limited to the above embodiment, and can be modified as appropriate. For example, although the embodiment described above describes an example in which the high-voltage cable protective member 100 of the present invention is used in the electric vehicle 200 using a motor as a power source, the present invention is not limited to a vehicle using only a motor as a power source, and is also applicable to a hybrid vehicle using a motor and an engine as power sources, for example.
In the above embodiment, the high-voltage cable protective member 100 having the external opening 30 located above the holding portion 50 is mounted on the vehicle body 210, but the mounting state is not limited to this. For example, the high-voltage cable protective member 100 may be attached to the vehicle body 210 in a state where the external opening 30 is located below the holding portion 50.
