Description

Technical Field

[0001] This patent relates to the field of battery compartments for electric vehicles (two-wheeled, three-wheeled, four-wheeled), and specifically to a movable battery compartment for an electric vehicle. Background Art

[0002] Battery compartments are widely used in electric vehicles. In existing electric vehicles, the battery compartment is installed on the vehicle frame. Due to the obstruction of the vehicle frame, it is inconvenient to take out the battery in the battery compartment, and the battery often shakes in the battery compartment. Summary of the Utility Model

[0003] The technical problem to be solved by this patent is to provide a movable battery compartment for an electric vehicle in view of the above-mentioned deficiencies of the prior art. The battery compartment body in this movable battery compartment for an electric vehicle can be moved outwards and extracted from the battery cavity of the vehicle frame, which is convenient for taking out the battery. After the battery compartment body is retracted into the battery cavity of the vehicle frame, the telescopic slide rail is locked. At the same time, the automatic pressing device above the battery moves with the battery and automatically presses the battery. After being pressed, the battery will not shake.

[0004] To achieve the above technical purpose, the technical solution adopted by this patent is as follows:

[0005] A movable battery compartment for an electric vehicle, comprising a battery compartment body for placing a battery, a telescopic slide rail, and an automatic pressing device. The battery compartment body is arranged in the battery cavity of the vehicle frame, and the battery compartment body is connected to the vehicle frame through the telescopic slide rail. A locking button for preventing the telescopic slide rail from extending is arranged on the telescopic slide rail. An automatic pressing device for pressing the battery is arranged on the top of the vehicle frame.

[0006] As a further improved technical solution of this patent, the automatic pressing device includes a pressing plate and pressing blocks. Both ends of the pressing plate are connected with pressing blocks. One pressing block is used for pressing the side wall of the battery, and the other pressing block is used for pressing the top of the battery. A pressing plate support is connected to the top of the vehicle frame. A through hole is arranged on the pressing plate support. The pressing plate passes through the through hole on the pressing plate support and can rotate and slide in the through hole.

[0007] As a further improved technical solution of this patent, the pressing block is made of a rubber pressing block.

[0008] As a further improved technical solution of this patent, the front side of the battery compartment body is connected to the front side of the battery cavity of the vehicle frame through a telescopic slide rail, and the rear side of the battery compartment body is connected to the rear side of the battery cavity of the vehicle frame through another telescopic slide rail. The left side surface of the battery cavity of the vehicle frame is an open structure, and the battery compartment body can slide out from the left side surface of the battery cavity under the action of the telescopic slide rail.

[0009] As a further improved technical solution of this patent, the telescopic slide rail includes an inner slide rail, a middle slide rail and an outer slide rail. The inner slide rail is slidably connected to the middle slide rail, the middle slide rail is slidably connected to the outer slide rail, the inner slide rail is connected to the battery compartment body, and the outer slide rail is connected to the vehicle frame.

[0010] As a further improved technical solution of this patent, a locking button for preventing the telescopic slide rail from extending is provided on one of the telescopic slide rails. The locking button includes a handle, a body and a protruding latch. The front end of the body is fixedly connected to the handle, and the lower part of the front end of the body is fixedly connected to the protruding latch. A card slot opening and a through opening for engaging with the protruding latch are provided at the front end of the outer slide rail, and the card slot opening communicates with the through opening. The through opening penetrates the front end of the outer slide rail. The bottom of the rear end of the body is rotatably connected to the front end of the side surface of the inner slide rail facing the middle slide rail.

[0011] When the handle is rotated downward, the protruding latch on the body can rotate from the card slot opening of the outer slide rail into the through opening. At this time, the inner slide rail can extend in and out along the middle slide rail, and the middle slide rail can extend in and out along the outer slide rail.

[0012] When the inner slide rail is pushed so that the inner slide rail shortens inward along the middle slide rail and the middle slide rail shortens inward along the outer slide rail to the shortest state of the telescopic slide rail, the front end wall of the middle slide rail contacts the rear end wall of the body and has an extrusion effect on the bottom of the rear end wall of the body, causing the body to rotate, thereby driving the protruding latch on the body to rotate from the through opening of the outer slide rail into the card slot opening, realizing the locking connection between the locking button and the outer slide rail.

[0013] As a further improved technical solution of this patent, a plurality of rollers are provided at the bottom of the battery cavity of the vehicle frame. The bottom of the battery compartment body contacts the rollers, thereby realizing the rolling connection between the bottom of the battery compartment body and the bottom of the battery cavity.

[0014] As a further improved technical solution of this patent, the rollers are made of nylon rollers.

[0015] The beneficial effects of this patent are:

[0016] When the locking button is pressed, the battery of this patent can move outwards along with the battery compartment body. The inner slide rail and the middle slide rail can extend, and the battery can move to the outside of the vehicle frame, facilitating the user to take out the battery. At the same time, nylon rollers are installed under the battery compartment body. When the battery compartment body moves outwards, the nylon rollers roll accordingly and support the battery compartment body. An automatic pressing device is installed above the battery. After the battery compartment body is pulled out, the pressing plate naturally droops under the action of gravity, and the pressing blocks at both ends of the pressing plate are separated from the battery, facilitating the user to take out the battery. When the battery is pushed inwards, the battery has a pushing effect on the pressing block at one end of the pressing plate. At this time, the pressing block and the pressing plate move with the battery until the pressing blocks at both ends of the pressing plate respectively press on the top and side of the battery. At the same time, after the inner slide rail and the middle slide rail of the battery compartment body are in place, the locking button on the retractable slide rail on one side automatically locks, and the battery compartment body is fixed and cannot move. At this time, the battery is also pressed by the pressing blocks on the pressing plate, and the battery is stable and does not sway. Description of the Drawings

[0023] The following further describes the specific implementation manners of this patent with reference to the drawings:

[0024] As Figures 1-2As shown in the figure, a movable battery compartment for an electric vehicle includes a battery compartment body 1 for placing a battery 4, two telescopic slide rails 2, and two automatic pressing devices 3. The battery compartment body 1 is arranged in the battery cavity of a vehicle frame 5. The battery compartment body 1 is slidably connected to the vehicle frame 5 through two telescopic slide rails 2. A locking button 6 for preventing the telescopic slide rail 2 from extending is arranged on the telescopic slide rail 2. Two automatic pressing devices 3 for pressing the battery 4 are arranged on the top of the vehicle frame 5. The bottom of the battery 4 is placed in the battery compartment body 1.

[0025] As Figure 2 shown in the figure, the automatic pressing device 3 includes a pressing plate 301 and a pressing block 302. Both ends of the pressing plate 301 are fixedly connected with a pressing block 302. The pressing block 302 is a rubber pressing block. One pressing block 302 is used for pressing the side of the battery 4, and the other pressing block 302 is used for pressing the top of the battery 4. Two pressing plate support members 501 are connected to the top of the vehicle frame 5. Through holes are arranged on both of the two pressing plate support members 501. The automatic pressing device 3 is installed in the through holes on the two pressing plate support members 501. Specifically, the pressing plate 301 passes through the through holes on the pressing plate support members 501 and the pressing plate 301 can freely rotate and slide in the through holes.

[0026] A notch is arranged at the bottom of the pressing plate support member 501. One end of the notch is rotatably connected with a rotating shaft, so that a through hole is formed between the rotating shaft and the notch. One end of the pressing plate 301 is freely lapped in the through hole.

[0027] The front side of the battery compartment body 1 is connected to the front side of the battery cavity of the vehicle frame 5 through a telescopic slide rail 2. The rear side of the battery compartment body 1 is connected to the rear side of the battery cavity of the vehicle frame 5 through another telescopic slide rail 2. The left side surface of the battery cavity of the vehicle frame 5 is an open structure, which is convenient for the battery compartment body 1 to be pulled out from the vehicle frame 5. The battery compartment body 1 can slide out from the left side surface of the battery cavity under the action of the telescopic slide rail 2.

[0028] As Figures 3-5 shown in the figure, the telescopic slide rail 2 includes an inner slide rail 201, a middle slide rail 202, and an outer slide rail 203. The inner slide rail 201 is slidably connected to the middle slide rail 202. The middle slide rail 202 is slidably connected to the outer slide rail 203. The inner slide rail 201 is connected to the battery compartment body 1 through screws or bolts. The outer slide rail 203 is connected to the vehicle frame 5 through screws or bolts.

[0029] A locking button 6 for preventing the telescopic slide rail 2 from extending is arranged on the telescopic slide rail 2 located at the rear side of the vehicle frame 5. As Figure 5, the locking button 6 includes a handle 601, a handle body 602 and a protruding latch 603. The front end of the handle body 602 is fixedly connected to the handle 601, and the lower part of the front end of the handle body 602 is fixedly connected to the protruding latch 603. A card slot 2032 for engaging with the protruding latch 603 is provided at the front end of the outer slide rail 203, and the card slot 2032 communicates with the through port 2031. The through port 2031 penetrates the front end of the outer slide rail 203. The bottom of the rear end of the handle body 602 is rotatably connected to the front end of the side surface of the inner slide rail 201 facing the middle slide rail 202 through a pin 604 near the corner position. The size of the pin 604 is small and will not hinder the extrusion of the bottom corner of the rear end wall of the handle body 602 by the middle slide rail 202 mentioned below.

[0030] When the handle 601 is rotated downward, the protruding latch 603 on the handle body 602 can rotate from the card slot 2032 of the outer slide rail 203 into the through port 2031. At this time, the inner slide rail 201 can extend and retract inside and outside along the middle slide rail 202, and the middle slide rail 202 can extend and retract inside and outside along the outer slide rail 203;

[0031] When the inner slide rail 201 is pushed so that the inner slide rail 201 shortens inward along the middle slide rail 202 and the middle slide rail 202 shortens inward along the outer slide rail 203 until the telescopic slide rail 2 is in a nearly shortest state (the protruding latch 603 on the handle body 602 has been pushed into the through port 2031 of the outer slide rail 203), the front end wall of the middle slide rail 202 contacts the bottom corner of the rear end wall of the handle body 602 and has an extrusion effect on the bottom corner of the rear end wall of the handle body 602, causing the handle body 602 to rotate until the rear end wall of the handle body 602 is parallel to the front end wall of the middle slide rail 202, thereby driving the protruding latch 603 on the handle body 602 to rotate from the through port 2031 of the outer slide rail 203 into the card slot 2032 (the state of the handle body 602 at this time can be referred to Figure 3 and Figure 5 ), realizing the locking connection between the locking button 6 and the outer slide rail 203.

[0032] A plurality of rollers 7 are provided at the bottom of the battery cavity of the vehicle frame 5. The bottom of the battery compartment body 1 contacts the rollers 7, thereby realizing the rolling connection between the bottom of the battery compartment body 1 and the bottom of the battery cavity. The roller 7 is made of nylon.

[0033] The operation process of this embodiment is as follows: As Figure 3As shown in the figure, when the handle 601 is pressed, the handle body 602 rotates, and the protruding latch 603 rotates from the slot opening 2032 of the outer slide rail 203 into the through opening 2031. At this time, when the handle 601 is pulled horizontally, the protruding latch 603 is pulled out from the through opening 2031 to disengage from the outer slide rail 203, and the inner slide rail 201 is pulled out from the middle slide rail 202, and the middle slide rail 202 can also be pulled out from the outer slide rail 203. The appropriate pulling-out length can be made according to the actual structure, as long as it is convenient to lift and remove the battery 4 from the battery compartment body 1. The partially pulled-out state can be seen in Figures 6-10 If it is necessary to insert the battery 4, that is, after pulling out the empty battery compartment body 1 from the vehicle frame 5, insert the battery into the battery compartment body 4, and then push the battery compartment body 4 horizontally inward or push the handle 601 horizontally. The middle slide rail 202 extends into the outer slide rail 203, and the inner slide rail 201 extends into the middle slide rail 202. The protruding latch 603 on the handle body 602 extends into the through opening 2031 of the outer slide rail 203. Then, the front end wall of the middle slide rail 202 contacts and presses the bottom corner of the rear end wall of the handle body 602, causing the handle body 602 to rotate, thereby driving the protruding latch 603 on the handle body 602 to rotate from the through opening 2031 of the outer slide rail 203 into the slot opening 2032, realizing the automatic locking and clamping of the locking button 6 and the outer slide rail 203. Under the action of this locking button 6, the telescopic slide rail 2 cannot extend.

[0034] In this embodiment, when the locking button 6 is pressed, the battery 4 can move outward with the battery compartment body 1, the inner slide rail 201 and the middle slide rail 202 can extend, and the battery 4 can move to the outside of the vehicle frame 5, which is convenient for the user to take the battery 4; at the same time, nylon rollers are installed below the battery compartment body 1. When the battery compartment body 1 moves outward, the nylon rollers roll accordingly and support the battery compartment body 1. An automatic pressing device 3 is installed above the battery 4. After the battery compartment body 1 is pulled out, the pressing plate 301 naturally hangs down under the action of gravity as shown in Figures 6-9 As shown in the figure, two rubber pressing blocks, that is, the pressing blocks 302, are assembled at both ends of the pressing plate 301. When the battery 4 is pushed inward, the battery 4 has a pushing effect on the pressing block 302 at one end of the pressing plate 301. At this time, the pressing block 302 and the pressing plate 301 move with the battery 4 until the two pressing blocks 302 at both ends of the pressing plate 301 are respectively pressed against the top and side of the battery 4, as shown in Figures 1-2 As shown in the figure, at the same time, after the inner slide rail 201 and the middle slide rail 202 of the battery compartment body 1 are in place, the locking button 6 on one side of the telescopic slide rail 2 is automatically locked, and the battery compartment body 1 is fixed and cannot move. At this time, the battery is also pressed by the four pressing blocks 302 on the two pressing plates 301, as shown in Figures 1-2 As shown in the figure, the battery is stable and does not shake.
