Description

Technical Field

[0001] This utility model relates to the field of automotive battery pack technology, and in particular to a lightweight automotive battery pack. Background Technology

[0002] The battery provides electrical energy to the vehicle's electrical system and is an essential component of the car. Batteries are generally located around the engine compartment, close to the engine. Whether the battery can function well depends on its overall condition in the vehicle, including temperature, mounting strength, vibration resistance, and distance from electrical equipment, among which mounting strength has a significant impact on the battery.

[0003] Traditional lightweight automotive battery packs have some drawbacks. In actual installation, although the design of fixing the battery to the electric vehicle chassis with bolts can make full use of the chassis space, when the vehicle's range drops abnormally by more than 20% and the software cannot locate the problem, this simple bolt fixing method also leads to the removal of the main fixing bolts during maintenance. Due to the long driving years of the vehicle, the bolt threads are very easy to wear or even strip. Utility Model Content

[0004] The main objective of this invention is to provide a lightweight automotive battery pack that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

A docking bracket is placed at the front end of the housing. An adjusting ring is movably connected to the inner side of the docking bracket. A connecting shaft is movably connected to the inner side of the adjusting ring. A control rod is fixedly connected to the rear end of the adjusting ring. A spring is sleeved on the outer side of the control rod. A limiting groove is formed at the rear end of the mounting bracket. A limiting block is slidably connected to the outer side of the control rod near the rear side of the spring. A limiting plate is placed at the upper end of the mounting bracket. A snap-fit ​​block is movably connected inside the limiting block. A screw with a No. 1 thread is threaded into the limiting plate.

[0007] Preferably, the docking frame is internally threaded with a No. 2 screw, the rear end of the control rod is fixedly connected with a baffle, and the front end of the fixing frame contacts the rear end of the docking frame near the outer shell.

[0008] Preferably, the connecting shaft extends into the interior of the docking frame, the connecting shaft is movably connected to the docking frame, the front end of the spring is fixedly connected to the rear end of the regulating ring, and the rear end of the spring is fixedly connected to the front end of the limiting block.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a lightweight automotive battery pack includes a housing 1. One end of the housing 1 is provided with an installation auxiliary mechanism 5. The installation auxiliary mechanism 5 includes a fixing frame 51 fixedly connected to one end of the housing 1. A docking frame 52 is placed at the front end of the housing 1. An adjustment ring 53 is movably connected to the inner side of the docking frame 52. A connecting shaft 54 ​​is movably connected to the inner side of the adjustment ring 53. A control rod 55 is fixedly connected to the rear end of the adjustment ring 53. A spring 56 is sleeved on the outer side of the control rod 55. A limiting groove 57 is opened at the rear end of the fixing frame 51. A limiting block 58 is slidably connected to the outer side of the control rod 55 near the rear side of the spring 56. A limiting piece 59 is placed at the upper end of the fixing frame 51. A snap-fit ​​block 510 is movably connected inside the limiting block 58. A screw 511 is threaded inside the limiting piece 59.

[0021] In this embodiment, the docking frame 52 is internally threaded with a second screw 512, the rear end of the control rod 55 is fixedly connected with a baffle 513, the front end of the fixing frame 51 contacts the rear end of the docking frame 52 near the outer shell 1, the connecting shaft 54 ​​extends into the interior of the docking frame 52, and the connecting shaft 54 ​​is movably connected to the docking frame 52, the front end of the spring 56 is fixedly connected to the rear end of the regulating ring 53, the rear end of the spring 56 is fixedly connected to the front end of the limiting block 58, the limiting block 58 is placed inside the limiting groove 57, the upper end of the snap-fit ​​block 510 is fixedly connected to the lower end of the limiting piece 59 near the inner side of the fixing frame 51, and the first screw 511 extends into the interior of the fixing frame 51, and the first screw 511 is threadedly connected to the fixing frame 51.

[0022] Specifically, first, unscrew screw 511, then pull the limiting piece 59, causing it to disengage the latch block 510 from the limiting block 58. Simultaneously, pull the limiting block 58 to slide along the control rod 55, disengaging it from the inner side of the limiting groove 57. This causes the limiting block 58 to stretch the spring 56. Then, pull the control rod 55, causing it to rotate the adjusting ring 53 around the connecting shaft 54. This disengages the fixing bracket 51 from the docking bracket 52, allowing the outer casing 1 to be removed, enabling the worker to... To inspect the battery cell 3, push the limiting plate 59 to cause the locking block 510 to disengage from the inside of the limiting block 58, and pull the limiting block 58 to slide along the control rod 55. Then pull the control rod 55 upward, which will cause the control rod 55 to drive the regulating ring 53 to rotate around the connecting shaft 54. This will facilitate the separation of the fixing frame 51 and the docking frame 52, thereby allowing the outer casing 1 to be disassembled quickly. This will facilitate the regular inspection of the battery cell 3 and avoid the wear or even stripping of the bolt threads.

[0023] In this embodiment, an inner compartment 2 is fixedly connected to the inner side of the outer casing 1. A battery cell 3 is installed inside the inner compartment 2. An isolation plate 4 is placed at the rear end of the battery cell 3. There are multiple sets of battery cells 3, and an isolation plate 4 is sandwiched between each pair of adjacent sets of battery cells 3.

[0024] Specifically, after the maintenance is completed, the outer casing 1 is placed back in its original position, and the fixing bracket 51 is brought into contact with the docking bracket 52. With the limiting block 58 in the tension of the spring 56, the control lever 55 is rotated into the fixing bracket 51, and then the limiting block 58 is released. This causes the spring 56 to lock the limiting block 58 into the limiting groove 57, thereby initially limiting the fixing bracket 51 to the rear end of the docking bracket 52. Then, the limiting plate 59 is placed on the fixing bracket 51, and the limiting plate 59 is pulled to lock the buckle block 510 into the limiting block 58. Then, the number one screw 511 is screwed into the limiting plate 59 and the fixing bracket 51 to limit the movement of the limiting block 58, thereby again limiting the fixing bracket 51 to the rear end of the docking bracket 52, thus reinforcing the installation of the outer casing 1.

[0025] Working principle:

[0026] During maintenance, first unscrew screw 511, then pull the limiting plate 59, causing the limiting plate 59 to disengage the latching block 510 from the limiting block 58. Simultaneously, pull the limiting block 58 to slide along the control rod 55, disengaging it from the inner side of the limiting groove 57, and causing the limiting block 58 to stretch the spring 56. Then pull the control rod 55, causing the control rod 55 to rotate the adjusting ring 53 around the connecting shaft 54. This disengages the fixing frame 51 from the docking frame 52, allowing the outer casing 1 to be removed, enabling workers to inspect the battery cell 3. After inspection, return the outer casing 1 to its original position, ensuring the fixing frame 51 contacts the docking frame 52. With the limiting block 58 stretching the spring 56, rotate the control rod 55 into the fixing frame 51, then release the limiting block 58. This causes the spring 56 to lock the limiting block 58 into the limiting groove 57, thus initially engaging the fixing frame 51. The first step is to limit the movement of the limiting plate 59 to the rear end of the docking frame 52. Then, the limiting plate 59 is placed on the fixing frame 51 and pulled to make the limiting plate 59 lock the buckle block 510 into the limiting block 58. Then, the first screw 511 is screwed into the limiting plate 59 and the fixing frame 51 to limit the movement of the limiting block 58. This again limits the fixing frame 51 to the rear end of the docking frame 52, thus strengthening the installation of the outer shell 1. By pushing the limiting plate 59, the limiting plate 59 drives the buckle block 510 to disengage from the inside of the limiting block 58 and pulls the limiting block 58 to slide along the control rod 55. Then, the control rod 55 is pulled upward, which causes the control rod 55 to drive the regulating ring 53 to rotate around the connecting shaft 54. This can facilitate the separation of the fixing frame 51 and the docking frame 52, so that the outer shell 1 can be quickly disassembled, which is convenient for the regular maintenance of the battery cell 3. Secondly, it avoids the wear or even stripping of the bolt threads.
