Embodiment 1
[0062] First, the structure will be described.
[0063] The structure of the charging port lock device of Example 1 is divided into "a general structure of an electric vehicle", "a structure of an external charging unit", "a detailed structure of a charging port lock device", and "a detailed structure of a lock mechanism". Be explained.
[0065] figure 1 An electric vehicle using the charging port lock device of Embodiment 1 is shown. Below, based on figure 1 A schematic configuration of an electric vehicle will be described.
[0066] Such as figure 1 As shown, the electric vehicle 1 using the charging port locking device of Embodiment 1 has a driving motor 2, a driving motor inverter 3, a DC / DC junction box 4, a battery pack 5, an external charging unit 6, an on-board charger 7, Air conditioning unit 8, 12 volt on-board battery 9.
[0067] The drive motor 2 is a drive source for travel having a speed reducer, and is a...
Embodiment 2
[0165] Example 2 is an example in which the second connection member connected to the disc 65 and the rod 61 is an intermediate rod instead of the slide pin 66 of the first embodiment.
[0166] First, the structure will be described.
[0167] Figure 13 Showing the first example of the lock mechanism when the middle lever connecting the lever and the disk is at the lock position in the charging port lock device of the second embodiment, Figure 14 Indicates the second instance of the locking mechanism, Figure 15 Indicates the third example of the locking mechanism. Below, based on Figure 13 to Figure 15 , the structure of the lock mechanism 60 of the second embodiment will be described.
[0168] Such as Figure 13 to Figure 15 As shown, the locking mechanism 60 has a rod 61 , a motor 62 (drive source), a worm 63 , a worm wheel 64 , a disk 65 (first connecting member), and an intermediate rod 68 (second connecting member).
[0169] Such as Figure 13 As shown, the leve...

Abstract
The invention provides a locking device for a charging port, a charging gun is inserted into the charging port and the charging gun is clamped and external charging is carried out, even through a load in the deblocking direction is applied to a limiting part, the clamping of the charging port is prevented from being relieved. The locking device for the charging port comprises a locking mechanism, when a clamping part of the charging gun and a clamped part of a common charging port are in a clamping state, the locking mechanism achieves a locking state through a rod to prevent the clamping state from being relieved and achieves a deblocking state through the rod to allow the clamping state to be relieved. In the locking device for the charging port, the locking device comprises a disk which is driven to rotate by a motor and a sliding pin which is connected with the disk and the rod and converts circular movements of the disk into rectilinear movements of the rod. In addition, under the condition that the rod is pressed to the deblocking direction near the biggest protrusion of the rod, the force, of the sliding pin, being applied to the disk faces the neighborhood of the rotation center of the disk.
Description
technical field [0001] The present invention relates to a charging port lock device that restricts the disengagement operation of the charging gun when external charging is performed by inserting the charging gun into a charging port of an electric vehicle and engaging it. Background technique [0002] Currently, there is known a plug lock device that uses a motor to rotate a transmission member, thereby causing a stopper to move linearly, so that the lock lever connected to the stopper is positioned at the locking position of the power supply plug (= charging gun). above the pawl to achieve a locked state (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2011-249165 [0004] However, in the conventional plug lock device, the rotational motion of the transmission member (external gear) is converted into linear motion of the stopper by meshing with the internal gear. Therefore, there is a problem that, when the...
