Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle technology, specifically relating to a battery swapping frame for electric vehicles. Background Technology

[0002] In electric vehicles and other new energy vehicles, the battery box, as a crucial energy supply unit, typically needs to be fixed to the vehicle's frame using a mounting frame. During the battery swapping process for electric vehicles, to accelerate the swapping process, the battery box is usually replaced.

[0003] Currently, common battery swapping frames consist of a main frame and multiple crossbeams. The main frame is connected to the vehicle frame and includes a front beam, left beam, rear beam, and right beam connected sequentially to form a ring. The multiple crossbeams are parallel to each other, and each crossbeam is fixedly connected to the left and right beams at both ends. The battery box is fixed to the crossbeams with bolts. With this structure, when a vehicle needs a battery swap, the existing battery box can be removed from the swapping frame, and then the replacement battery box can be installed on the swapping frame, thus enabling battery replacement. However, because the installation position of the battery box on the swapping frame is fixed, this means that the swapping frame can only be used with one type of battery box, thus limiting its applicability.

Second mounting holes are provided on the left beam 102, the first sliding beam 3, the second sliding beam 4, and the right beam 104. When the battery box is positioned between the left beam 102 and the first sliding beam 3, the mounting plates on both sides of the battery box are connected to the left beam 102 and the first sliding beam 3, respectively. In this case, the battery box can be fastened to the left beam 102 and the first sliding beam 3 using bolts and nuts. Specifically, the bolts pass through the first and second mounting holes sequentially and are threadedly locked to the nuts, allowing the mounting plates on both sides of the battery box to be fastened to the left beam 102 and the first sliding beam 3, respectively. When the battery box is positioned between the right beam 104 and the second sliding beam 4, the mounting plates on both sides of the battery box are connected to the right beam 104 and the second sliding beam 4 respectively. At this time, the battery box can be fastened to the right beam 104 and the second sliding beam 4 by bolts and nuts. That is, the bolts pass through the first mounting hole and the second mounting hole in sequence, extend out and are threadedly locked with the nuts, so that the mounting plates on both sides of the battery box can be fastened to the right beam 104 and the second sliding beam 4 respectively.

[0030] In some embodiments of this application, the motor 201 and the lead screw 202 can be connected by a coupling. When the motor 201 rotates, it drives the lead screw 202 to rotate. When the lead screw 202 rotates, it drives the first threaded sleeve 203 and the second threaded sleeve 204 to move along the axial direction of the lead screw 202.

[0031] In some embodiments of this application, the first threaded sleeve 203 is provided with a first internal thread, and the first internal thread and the first thread are threadedly engaged; the second threaded sleeve 204 is provided with a second internal thread, and the second internal thread and the second thread are threadedly engaged.

[0032] In some embodiments of this application, when the motor 201 rotates forward, it drives the lead screw 202 to rotate forward. When the lead screw 202 rotates, it drives the first threaded sleeve 203 and the second threaded sleeve 204 to move towards each other. When the first threaded sleeve 203 moves, it drives the first end of the first extension rod 205 to move toward the side where the second threaded sleeve 204 is located. When the first end of the first extension rod 205 moves, it drives its second end to apply a rightward force to the first sliding beam 3, causing the first sliding beam 3 to move to the right. At this time, the distance between the first sliding beam 3 and the left beam 102 increases. Furthermore, when the first threaded sleeve 203 moves, it drives the first end of the second extension rod 206 to move toward the side where the second threaded sleeve 204 is located. When the first end of the first extension rod 205 moves, it drives its second end to apply a leftward force to the second sliding beam 4, causing the second sliding beam 4 to move to the left. At this time, the distance between the second sliding beam 4 and the right beam 104 increases. When the second threaded sleeve 204 moves, it causes the first end of the third extension rod 207 to move toward the side where the first threaded sleeve 203 is located. The movement of the first end of the third extension rod 207 causes its second end to exert a rightward force on the first sliding beam 3, causing the first sliding beam 3 to move to the right. At this time, the distance between the first sliding beam 3 and the left beam 102 increases. Furthermore, when the second threaded sleeve 204 moves, it causes the first end of the fourth extension rod 208 to move toward the side where the first threaded sleeve 203 is located. The movement of the first end of the fourth extension rod 208 causes its second end to exert a leftward force on the second sliding beam 4, causing the second sliding beam 4 to move to the left. At this time, the distance between the second sliding beam 4 and the right beam 104 increases.

[0033] In some embodiments of this application, when the motor 201 reverses, it drives the lead screw 202 to rotate in the opposite direction. When the lead screw 202 rotates, it drives the first threaded sleeve 203 and the second threaded sleeve 204 to move in opposite directions. When the first threaded sleeve 203 moves, it drives the first end of the first extension rod 205 to move away from the second threaded sleeve 204. When the first end of the first extension rod 205 moves, it drives its second end to apply a leftward force to the first sliding beam 3, causing the first sliding beam 3 to move to the left. At this time, the distance between the first sliding beam 3 and the left beam 102 decreases. Furthermore, when the first threaded sleeve 203 moves, it drives the first end of the second extension rod 206 to move away from the second threaded sleeve 204. When the first end of the first extension rod 205 moves, it drives its second end to apply a rightward force to the second sliding beam 4, causing the second sliding beam 4 to move to the right. At this time, the distance between the second sliding beam 4 and the right beam 104 decreases. When the second threaded sleeve 204 moves, it causes the first end of the third extension rod 207 to move away from the first threaded sleeve 203. When the first end of the first extension rod 205 moves, it causes its second end to apply a force to the left on the first sliding beam 3, causing the first sliding beam 3 to move to the left. At this time, the distance between the first sliding beam 3 and the left beam 102 decreases. Furthermore, when the second threaded sleeve 204 moves, it causes the first end of the fourth extension rod 208 to move away from the first threaded sleeve 203. When the first end of the fourth extension rod 208 moves, it causes its second end to apply a force to the right on the second sliding beam 4, causing the second sliding beam 4 to move to the right. At this time, the distance between the second sliding beam 4 and the right beam 104 decreases.

[0034] In the above-mentioned scheme of this application, the battery box swapping frame includes a main frame 1, a pushing mechanism 2, a first sliding beam 3, and a second sliding beam 4. The main frame 1 includes a front beam 101, a left beam 102, a rear beam 103, and a right beam 104 connected in sequence and forming a ring frame. One end of the first sliding beam 3 is slidably connected to the front beam 101, and the other end of the first sliding beam 3 is slidably connected to the rear beam 103. One end of the second sliding beam 4 is slidably connected to the front beam 101, and the other end of the second sliding beam 4 is slidably connected to the rear beam 103. One of the two battery boxes is fixed between the left beam 102 and the first sliding beam 3, and the other is fixed between the right beam 104 and the second sliding beam 4. The pushing mechanism 2 includes a motor 201, a lead screw 202, a first threaded sleeve 203, a second threaded sleeve 204, a first extension rod 205, a second extension rod 206, a third extension rod 207, and a fourth extension rod 208. The motor 201 and The lead screw 202 is connected to the transmission system. A first threaded sleeve 203 and a second threaded sleeve 204 are both fitted onto the lead screw 202. The lead screw 202 has a first thread and a second thread, with opposite directions of rotation. The first threaded sleeve 203 and the first thread are threadedly connected, as are the second threaded sleeve 204 and the second thread. One end of the first extension rod 205 is rotatably connected to the first threaded sleeve 203, and the other end is rotatably connected to the first sliding beam 3. One end of the second extension rod 206 is rotatably connected to the first threaded sleeve 203, and the other end is rotatably connected to the second sliding beam 4. One end of the third extension rod 207 is rotatably connected to the second threaded sleeve 204, and the other end is rotatably connected to the first sliding beam 3. One end of the fourth extension rod 208 is rotatably connected to the second threaded sleeve 204, and the other end is rotatably connected to the second sliding beam 4. With this structure, when a vehicle needs a battery swap and the replacement battery box is a different size from the original battery box, the original battery box can be removed first. Then, the motor 201 controls the lead screw 202 to rotate. When the lead screw 202 rotates, it drives the first threaded sleeve 203 and the second threaded sleeve 204 to move closer or further apart. When the first threaded sleeve 203 and the second threaded sleeve 204 move, they drive the first extension rod 205, the second extension rod 206, the third extension rod 207, and the fourth extension rod 208 to move and expand or contract, thereby adjusting the distance between the first sliding beam 3 and the left beam 102, and the distance between the second sliding beam 4 and the right beam 104. This allows battery boxes of different sizes to be installed between the first sliding beam 3 and the left beam 102, and between the second sliding beam 4 and the right beam 104, thus improving the applicability of the battery swapping frame.

[0035] Furthermore, this application can simultaneously install two battery boxes. When the distance between the left beam 102 and the first sliding beam 3 is not equal to the distance between the right beam 104 and the second sliding beam 4, the size of the battery box placed between the left beam 102 and the first sliding beam 3 can be different from the size of the battery box placed between the right beam 104 and the second sliding beam 4, thereby enabling the battery swapping frame of this application to simultaneously install two different sizes of battery boxes.

[0037] In some embodiments of this application, the battery swapping frame further includes a first bolt 10 and a first nut 11.

The first bolt 10 passes through the first through hole, the first elongated hole 5, and the second through hole in sequence, and extends out and is threadedly connected to the first nut 11. With this structure, the mutual restraint between the first bolt 10 and the hole walls of the first through hole further improves the stability of the installation and sliding of the first sliding beam 3.

[0038] In some embodiments of this application, the upper and lower surfaces of the front beam 101 are provided with first elongated holes 5, and the first bolt 10 is inserted into the first elongated holes 5 on both the upper and lower surfaces of the front beam 101.

[0039] In some embodiments of this application, both the first and second perforations are circular holes.

[0040] In some embodiments of this application, the second sliding beam 4 includes a second tube and two second U-shaped members. The second tube is disposed between the front beam 101 and the rear beam 103. The two second U-shaped members are respectively connected to both ends of the second tube.

The front beam 101 is located in the second U-shaped groove of one of the two second U-shaped members, and the rear beam 103 is located in the second U-shaped groove of the other of the two second U-shaped members. With this structure, the front beam 101 can be mutually restrained by the groove wall of the second U-shaped groove at one end of the second sliding beam 4, and the rear beam 103 can be mutually restrained by the groove wall of the second U-shaped groove at the other end of the second sliding beam 4, thereby improving the stability of the installation and sliding of the second sliding beam 4.

[0041] In some embodiments of this application, a second bolt and a second nut are also included. Both the front beam 101 and the rear beam 103 are provided with a second elongated hole 6, which extends along the length of the front beam 101. The second U-shaped member includes a second upper plate, a second connecting plate, and a second lower plate connected in sequence. The second connecting plate is connected to the second tube body. A third through hole is provided on the second upper plate, and a fourth through hole is provided on the second lower plate. The second bolt passes through the third through hole, the second elongated hole 6, and the fourth through hole in sequence, extending out and threadedly connected to the second nut. With this structure, the mutual restraint of the second bolt and the hole walls of the second through hole further improves the stability of the installation and sliding of the second sliding beam 4.

[0042] In some embodiments of this application, the upper and lower surfaces of the front beam 101 are provided with second elongated holes 6, and the second bolt is inserted into the second elongated holes 6 on both the upper and lower surfaces of the front beam 101.

[0044] In some embodiments of this application, such as Figure 1 As shown, a first telescopic beam 7 is provided between the first sliding beam 3 and the left beam 102. The first telescopic beam 7 includes a first inner tube and a first outer tube. The first inner tube is sleeved inside the first outer tube. The first inner tube is connected to the left beam 102, and the first outer tube is connected to the first sliding beam 3. With this structure, the left beam 102 and the first sliding beam 3 can be connected through the first telescopic beam 7, thereby improving the reliability of the connection between the left beam 102 and the first sliding beam 3, and thus improving the overall stability of the battery swapping frame. Simultaneously, when the first sliding beam 3 moves, it can drive the first inner tube and the first outer tube in the first telescopic beam 7 to move relative to each other to achieve retraction, avoiding the first telescopic beam 7 restricting the movement of the first sliding beam 3. In addition, the first telescopic beam 7 can also support the battery box, thereby improving the stability of the battery box after installation.

[0045] In some embodiments of this application, multiple through holes are provided on both the first inner tube and the first outer tube. Thus, after the relative movement of the first inner tube and the first outer tube achieves extension and retraction, bolts can be used to pass through the through holes on the first inner tube and the first outer tube in sequence and lock them with nuts, so that the first inner tube and the first outer tube are fixed by bolts and nuts, thereby further improving the reliability of the connection between the left beam 102 and the first sliding beam 3.

[0046] In some embodiments of this application, a second telescopic beam 8 is provided between the second sliding beam 4 and the right beam 104. The second telescopic beam 8 includes a second inner tube and a second outer tube, with the second inner tube sleeved inside the second outer tube.

With this structure, the second sliding beam 4 and the right beam 104 can be connected via the second telescopic beam 8, thereby improving the reliability of the connection between the second sliding beam 4 and the right beam 104, and thus improving the overall stability of the battery swapping frame. Simultaneously, when the second sliding beam 4 moves, it can drive the second inner tube and the second outer tube in the second telescopic beam 8 to move relative to each other to achieve retraction, avoiding the second telescopic beam 8 restricting the movement of the second sliding beam 4. Furthermore, the second telescopic beam 8 can also support the battery box, thereby improving the stability of the battery box after installation.

[0047] In some embodiments of this application, multiple through holes are provided on both the second inner tube and the second outer tube. Thus, after the relative movement of the second inner tube and the second outer tube achieves expansion and contraction, bolts can be used to pass through the through holes on the second inner tube and the second outer tube in sequence and lock them with nuts, so that the second inner tube and the second outer tube are fixed by bolts and nuts, thereby further improving the reliability of the connection between the second sliding beam 4 and the right beam 104.
