Description

  The present invention relates to a vehicle battery protection structure, and more particularly to a vehicle battery protection structure for protecting a battery mounted on a vehicle.

In an electric vehicle (hereinafter referred to as “vehicle”) such as a hybrid vehicle (HV) and an electric vehicle (EV), a battery as a power source is mounted and high voltage units such as an inverter and a motor are mounted in a front room. Has been.
However, in such a vehicle, a space for installing a 12V battery (hereinafter referred to as “battery”) is reduced in the front room because high voltage units such as an inverter and a motor are mounted in the front room. Yes.
For this reason, as shown in FIGS. 11 to 14, in the vehicle 101, the battery 102 is often installed near the luggage room 104 behind the rear seat 103. A plus (+) terminal 105 and a minus (−) terminal 106 are provided on the battery 102. The plus (+) terminal 105 and the minus (−) terminal 106 are made of metal parts.
In this case, an access hole 107 accessible to the negative (−) terminal 106 as the battery terminal of the battery 102 is installed in order to turn off the power supply during maintenance. Due to the presence of the access hole 107, the cable terminal 109 of the battery cable 108 can be removed from the minus (-) terminal 106. The cable terminal 109 is made of a metal part.
As such a structure, there are the following prior art documents.

JP 2004-200067 A

  In the battery terminal protective cover according to Patent Document 1, the cover part (protective cover) includes a stopper and a coil spring for restricting the mounting direction of the battery terminal to the electrode post, and the coil spring is attached to the battery with the cover part opened. It is a structure to contact.

Conventionally, in the structure shown in FIGS. 11 to 14, when the battery 102 exists in the vicinity of the luggage room 104, the battery 102 is covered with a protective cover (resin component) 110 that opens and closes the access hole 107. When the protective cover 110 is removed, the minus (−) terminal 106 can be accessed.
When the power is turned off for maintenance or the like, the cable terminal 109 of the battery cable 108 is removed from the minus (−) terminal 106 of the battery 102 as shown in FIG.
However, when the cable terminal 109 of the battery cable 108 is removed from the negative terminal 106 of the battery 102 in this way, the cable terminal 109 of the battery cable 108 becomes free (free) as shown in FIG. There is a risk of short circuit due to contact with the negative (−) terminal 106. Further, even during simple work, it is necessary to perform a process such as winding an insulating tape around the cable terminal 109 of the battery cable 108, and the structure is not considered in view of workability, and improvement has been desired.
Moreover, in said cited reference 1, although the protection at the time of a connection is performed using another component, the protection function after removing the cable terminal of a battery cable is not provided, but the improvement was desired.

1 to 10 show an embodiment of the present invention.
As shown in FIGS. 8 and 9, the vehicle 1 is an electric vehicle including a hybrid vehicle (HV), an electric vehicle (EV), and the like.
A vehicle 1 has a high-voltage unit 6 such as an inverter 3, a generator 4, and a motor 5 mounted in a front room 2. Therefore, in the vehicle 1, there is little space in the front room 2 on the front side in the vehicle longitudinal direction X, and a 12V battery (hereinafter referred to as “battery”) 7 is installed near the luggage room 9 behind the rear seat 8.
Further, the vehicle 1 is provided with front wheels 10 and 10, rear wheels 11 and 11, and headlights 12 and 12.

As shown in FIGS. 5 to 9, in the vehicle 1, a luggage room 9 is partitioned and formed behind the rear seat 8 and in a horizontal direction by a plate-shaped luggage board 13.
Further, in the vehicle 1, a vehicle fixture 14 and a battery 7 are mounted below the luggage board 13 as shown in FIG. 6. The vehicle equipment 14 and the battery 7 are disposed below the height position of the rear seat 8. The vehicle equipment 14 is arranged with its longitudinal direction oriented in the vehicle width direction Y. The battery 7 is arranged on the right side of the vehicle equipment 14 with the longitudinal direction oriented in the vehicle longitudinal direction X.
A plus (+) terminal 15 and a minus (−) terminal 16 are provided on the upper portion of the battery 7 as battery terminals. The plus (+) terminal 15 and the minus (−) terminal 16 are made of metal parts. The plus (+) terminal 15 protrudes upward from the upper surface of the battery 7 and is disposed at the rear end. The minus (−) terminal 16 is disposed at the front end portion at a recess 17 that is recessed from the upper surface of the battery 7.

As shown in FIGS. 2 to 4, as a battery terminal, for example, a negative (−) terminal 16 of the battery 7 is connected to a cable terminal 19 of a battery cable 18 for supplying electric power to the electric load of the vehicle 1. The The cable terminal 19 is made of a metal part.
Further, the battery 7 is provided with a protective cover 20 that covers at least the upper part of the battery 7.
As shown in FIGS. 6 and 7, the protective cover 20 is a required surface area covering the upper part of the battery 7 and is made of a thin plate-like insulator (resin component). The protective cover 20 includes a notch 21 that can be opened and closed only in an area necessary for connecting the minus (−) terminal 16 of the battery 7 and the cable terminal 19 of the battery cable 18.
The notch 21 forms an access hole 22, and as shown in FIG. 7, the base portion is cut away so as to face the minus (−) terminal 16, and the minus (−) terminal 16 is accessed. It can be done.
The cut portion 21 includes a folded portion 23 at the base portion and a cover portion 25 formed by a U-shaped cut line 24 so as to form the access hole 22. In this case, the cut portion 21 is formed such that the longitudinal direction is directed in the vehicle longitudinal direction X.

  In this embodiment, as shown in FIGS. 1 and 7, when the minus (−) terminal 16, the battery cable 18, and the cable terminal 19 of the battery 7 are connected, the notch 21 closes the access hole 22. As shown in the figure, it has a function of covering the upper part of the minus (−) terminal 16 and the cable terminal 19 with the cover part 25. Thereby, even when the minus (−) terminal 16 of the metal part and the cable terminal 19 contact each other by mistake, there is no possibility that the vehicle body and the battery 7 are short-circuited.

At the time of maintenance, as shown in FIG. 2, first, when the access hole 22 is opened by grasping the tip of the cover portion 25 of the cut portion 21 of the protective cover 20, the minus (−) terminal 16 of the battery 7 and the battery cable are opened. 18 and the cable terminal 19 appear, and the minus (−) terminal 16 can be accessed, and the battery cable 18 and the cable terminal 19 are removed from the minus (−) terminal 16 of the battery 7 as shown in FIG. Can do.
In this case, as shown in FIG. 4, the notch portion 21 includes the cable terminal 19 of the battery cable 18 so that the cable terminal 19 of the battery cable 18 in the free state does not contact the minus (−) terminal 16 of the battery 7. Is removed from the negative (−) terminal 16 of the battery 7, and the cover 25 is sandwiched between the negative (−) terminal 16 and the cable terminal 19. Thus, since the cover part 25 of the notch part 21 is inserted | pinched between the minus (-) terminal 16 and the cable terminal 19, the possibility of short-circuiting can be eliminated.

  As a result, in the vehicle 1 composed of a hybrid vehicle (HV), an electric vehicle (EV), or the like, the negative (−) terminal 16 of the battery 7 can be accessed without removing the protective cover 20 itself. 19 can be easily detached. Further, when the cable terminal 19 of the battery cable 18 is removed from the minus (−) terminal 16 of the battery 7, the cut portion 21 of the protective cover 20 is sandwiched between the minus (−) terminal 16 and the cable terminal 19. As a result, contact between the minus (−) terminal 16 and the outside can be prevented, thereby improving workability during maintenance.

  In this embodiment, as shown in FIG. 10, in the protective cover 20, the cut portion 21 can be formed so that the longitudinal direction is oriented in the vehicle width direction Y, and the same effect can be obtained.

  The vehicle battery protection structure according to the present invention can be applied to various vehicles.
