Battery fixing device

The present invention relates to a fixing device, in particular to a battery fixing device of an electric vehicle.

Electric vehicles designed with exchangeable batteries are now very popular. Such electric vehicles often place the battery in the battery slot of the storage box to couple with the connector at the bottom of the battery slot. When the battery is inserted into the battery slot, pass through Close the seat cushion to close the battery slot. At this time, the battery is pressed and fixed through the bottom surface of the seat cushion to prevent the battery from jumping up and down.

However, when an electric vehicle is driving on a bad road with poor road conditions, the battery will still jump up and down due to the strong vibration of the vehicle and insufficient pressing force of the seat cushion, causing the battery and the connector to separate and cause a dangerous situation of power interruption during driving. On the one hand, the impact caused by the up and down jump of the battery will also cause deformation of the seat cushion and the battery bottom plate, which will further increase the beating amplitude of the battery, forming a vicious circle and greatly affecting driving safety.

Referring to Figures 1, 2, and 3, an embodiment of the battery fixing device 1 of the present invention is suitable for fixing a battery 22 accommodated in a battery slot 21. The battery 22 forms a slot 221 and has a An inclined surface 222 located in the slot 221. This embodiment also needs to be used in conjunction with a cushion 3, which includes a cushion body 31 and a supporting protrusion 32 extending downward from the bottom surface of the cushion body 31. It should be noted that, in a preferred case, the two battery fixing devices 1 are respectively fixed on the left and right opposite sides of the battery 22 (in this way, the seat cushion 3 includes two abutting protrusions 32), but also A battery fixing device 1 can be used alone, and it is not limited to this.

Referring to FIGS. 2, 3, and 4, the battery fixing device 1 includes a base 11 disposed on either the left or right side of the battery 22, and an inclined top pin slidably disposed on the base 11 12. A compression spring 13 arranged between the base 11 and the inclined roof pin 12, and a fixing mechanism 14 arranged on the inclined roof pin 12. The base 11 includes a main seat body 111 fixed to the vehicle body on the left or right side of the battery 22, a fixed top plate 112 fixed to the top surface of the main seat body 111 through a screw lock, and two main seat bodies 111 The positioning member 113 is inclined downward. The main base 111 forms a sliding groove 114 extending in the left-right direction, and the two positioning members 113 are respectively located on opposite sides of the sliding groove 114 in the front-rear direction and alternately arranged in the left-right direction. The fixed top plate 112 and the main base 111 cooperate to define a gap for the inclined top pin 12 to pass through.

The inclined top bolt 12 includes an outer frame portion 122 surrounding an operating port 121 and located outside the base 11, and an outer frame portion 122 that extends horizontally inward from the outer frame portion 122 and passes through the The pin body 123 of the gap. The outer frame 122 extends outwardly and obliquely downwards, and the operation port 121 faces the sliding groove 114. The fixing mechanism 14 includes an operating knob 141 rotatably limited to the outer frame portion 122, and two clamping plates 142 extending from the bottom end of the operating knob 141 in the radial direction. The top end of the operating knob 141 is exposed at the operating port 121 and has a corresponding structure for inserting keys or other tools. The sliding groove 114 passes through the bottom end of the operating knob 141, and the clamping plates 142 are located under the sliding groove 114.

Referring to Figures 2, 3, and 5, when the seat cushion 3 is closed, the abutting protrusion 32 moves downward with the cushion body 31, and presses down against the exterior after contacting the inclined top pin 12 The frame portion 122, the outer frame portion 122 can convert the downward displacement of the abutting protrusion 32 into a horizontal inward displacement, so that the inclined top pin 12 is separated from the base 11 by a displacement as shown in FIG. 3 Move to a locked position as shown in Figure 5. When the inclined top plug 12 is in the unlocked position, the abutting protrusion 32 has not yet pressed against the outer frame portion 122, and the pin body 123 is not extended into the slot 221 of the battery 22. At this time, the The battery 22 is not restricted, so it can be taken out of the battery slot 21. In the process of moving the inclined top pin 12 from the unlocked position to the locked position, the end of the pin body 123 is in sliding contact with the inclined surface 222 and moves along the inclined surface 222 to achieve the guiding direction and the smoothness of the lifting action The efficacy. When the inclined top bolt 12 is in the locked position, the pin body 123 is inserted into the slot 221, and the outer frame portion 122 compresses the compression spring 13 to store elastic potential energy. At this time, the inclined top bolt 12 Snap the battery 22 so that the battery 22 cannot be taken out of the battery slot 21, and fix the lower end of the battery 22 in the battery slot 21, while the upper end is The inclined roof pin 12 is fixed to achieve a better fixing effect. When the seat cushion 3 is opened again, the compression spring 13 will drive the inclined roof pin 12 to reset to the unlocked position. It should be noted that the battery 22 may not have the slot 221, and the inclined top pin 12 can extend above the top surface 223 of the battery 22 (the size of the battery 22 and the battery fixing device 1 must be adjusted relatively And corresponding), and press down the top surface 223 of the battery 22 to achieve a limit effect.

Refer to Figure 2, Figure 4, and Figure 6, due to regulations, batteries exceeding 50 volts must be fixed on the car body at all times and must be unlocked with a tool. In order to comply with the aforementioned specifications, the battery fixing device 1 is placed on the promotion When 123 is in the locked position, the operating knob 141 can also be turned by a tool such as a key, so that the clamping plates 142 are rotated from the direction parallel to the sliding groove 114 as shown in FIG. 4 to perpendicular to the sliding groove 114 as shown in FIG. And latch the positioning members 113 to keep the inclined top pin 12 in the locked position. The fixing mechanism 14 uses the aforementioned mechanism so that when the seat cushion 3 (see FIG. 3) is opened, the battery 22 can still be fixed and limited by the inclined top pin 12, so that the battery 22 can be fixed to The battery slot 21 can correspond to different types of batteries and meet its specifications.

In summary, the present invention converts the downward movement stroke of the seat cushion 3 into a horizontal inward movement stroke through the inclined outer frame portion 122, and enables the pin body 123 to be inserted into the battery 22. In the groove 221 (or pressing the battery 22), the battery 22 can be restrained with better locking strength, so as to further restrain the battery 22 from jumping up and down, improve the problem of deformation of the seat cushion 3 and the bottom plate of the battery groove 21, and prevent A dangerous situation of power failure occurs when driving, Therefore, it can indeed achieve the purpose of cost and new style.

However, the above-mentioned are only examples of the present model, and should not be used to limit the scope of implementation of the present model, all simple equivalent changes and modifications made in accordance with the patent scope of the present model application and the contents of the patent specification still belong to This new patent covers the scope.
