Detailed Description
The following describes the embodiments of the present invention with reference to the accompanying drawings.
The application discloses extraction formula battery with novel battery connection structure, this extraction formula battery include group battery 2, go up connector 3, lower connector 4 and elastomer 5. Optionally, the removable battery further includes a battery case 1, and the battery pack 2 is disposed in the battery case 1.
The battery pack 2 has an upper connector 3 fixed to the bottom thereof, and as shown in fig. 1, the upper connector 3 is usually embedded in the battery pack 2. As shown in fig. 2, the upper connector 3 is provided with a guide sleeve 3a for electrical leading, and the shape and number of the guide sleeve 3a are configured according to practical situations, which is not limited in the present application.
The bottom of the lower connector 4 abuts against the bottom contact surface of the battery pack 2 through the elastic body 5, and there are various situations on the bottom contact surface of the battery pack 2, for example, a common situation is that the battery pack 2 is sleeved in the battery box 1 and directly contacts with the inner bottom surface of the battery box 1, and then the bottom contact surface of the battery pack 2 is the inner bottom surface of the battery box 1, which is only the case shown in fig. 1. Or the battery pack 2 is also sleeved in the battery box 1 and indirectly contacts with the bottom surface inside the battery box 1 through other components, and the contact surface at the bottom of the battery pack 2 is the upper surface of the other components contacted with the battery pack. Or, the battery pack 2 is also sleeved in the battery box 1, but the bottom of the battery box 1 is open, the battery pack 2 is in contact with other parts at the bottom opening of the battery box 1, and the contact surface at the bottom of the battery pack 2 is the upper surface of the other parts in contact with the battery pack. Or, the battery pack 2 is not sleeved in the battery box 1, but directly contacts with other components, and the contact surface at the bottom of the battery pack 2 is the upper surface of the other components contacted with the battery pack. Each of the above cases is included in the structure of the present application.
The lower connector 4 is abutted against the bottom contact surface of the battery pack 2 by at least one elastic body 5, but in order to improve the abutting reliability, a plurality of elastic bodies 5 are usually adopted, for example, at least two elastic bodies 5 are uniformly distributed on the bottom of the lower connector 4, for example, one elastic body 5 is respectively arranged at four corners of the lower connector 4 in the figure. The elastic body 5 is any elastic body, and the shape and material of the elastic body are not limited in the present application, for example, a spring may be used as a common elastic body.
Referring to fig. 3, a guide pin 4c matching with the guide sleeve 3a of the upper connector 3 is disposed on the lower connector 4, and the guide pin 4c is electrically connected to a power line 4d for power supply and lead-out. When the battery pack 2 is installed, the upper connector 3 at the bottom of the battery pack is correspondingly inserted into the lower connector 4 at the contact surface, the guide pin 4c on the lower connector 4 is correspondingly inserted into the guide sleeve 3a on the upper connector 3 to form electrical connection, and meanwhile, the lower connector 4 compresses the elastic body 5 to move up and down under the action of gravity of the battery pack 2. When the electric vehicle runs and jolts to cause the removable battery to run in a jumping state, the elastic action of the elastic body 5 can ensure that the upper connector 3 and the lower connector 4 are fixedly combined, power failure is avoided, and continuous power output is kept.
In the present application, as shown in fig. 3, the lower connector 4 includes a lower connection holder 4a and a lower connection holder 4b in addition to a guide pin 4c and a power cord 4d, both of which are provided on the lower connection holder 4 b. The lower connecting fixing seat 4a is a hollow structure with an open top, and the size of the open top 4e is smaller than that of the lower connecting seat 4 b. The lower connecting fixing seat 4a is fixed on the bottom contact surface of the battery pack 2, and the bottom contact surface of the battery pack 2 is the bottom surface inside the battery box 1, as shown in fig. 4 and 5, at this time, a containing cavity 6 is formed between the lower connecting fixing seat 4a and the bottom contact surface of the battery pack 2 (i.e., the bottom surface inside the battery box 1), as shown in fig. 6, the lower connecting seat 4b is arranged in the containing cavity 6, and the bottom of the lower connecting seat 4b is abutted to the bottom contact surface of the battery pack 2 through the elastic body 5. As shown in fig. 7, in order to ensure the abutting reliability, the elastic body 5 may be embedded in a groove at a corresponding position at the bottom of the lower connector 4, and further, the elastic body 5 may be sleeved on a guide post in the groove at the corresponding position at the bottom of the lower connector 4.
The lower connecting seat 4b is supported by the elastic force of the elastic body 5 in a natural state and is arranged at the top opening 4e of the lower connecting fixed seat 4 a. And as shown in fig. 7, the upper portion of the lower connecting holder 4b in the natural state passes through the opening of the lower connecting holder 4a and protrudes out of the upper surface of the lower connecting holder 4 a.
When the battery pack 2 is mounted, the upper connector 3 at the bottom of the battery pack is inserted into the lower connecting seat 4b, as shown in fig. 7, the lower connecting seat 4b moves downwards under the pressure of the battery pack 2, slides relative to the lower connecting seat 4a and compresses the elastic body 5, the lower connecting seat 4b retracts into the accommodating cavity 46 between the lower connecting seat 4a and the battery box 1 to be separated from the lower connecting seat 4a in the sliding process, and meanwhile, the elastic force of the elastic body 5 reversely pushes the lower connecting seat 4b to move upwards, so that the upper connector 3 and the lower connector 4 are firmly combined.
Optionally in this application, this removable battery still includes storage box 7, as shown in fig. 8 and fig. 9, storage box 7 fixes in the periphery of battery case 1, and its inner chamber switches on with the inner chamber of battery case 1 in order to supply group battery 2 to insert in battery case 1, and storage box 7 mainly includes diapire and lateral wall, forms between its lateral wall and the group battery 2 and puts the thing space 8 and be used for putting the thing.
The storage box 7 actually has various morphological structures, the height, the width and the like can be set in a user-defined mode, and the specific connecting position of the storage box 7 and the battery box 1 can be adjusted as long as the storage space 8 is formed between the storage box 7 and the battery pack 2. For example, fig. 8 and 9 show the storage box 7 as a single-layer rectangular structure, but may be any other shape, such as a circular shape. Alternatively, the storage box 7 may be a multi-layer sleeve structure instead of a single-layer structure, as shown in fig. 10, which includes two-stage structures with different opening sizes. And the storage box 7 can be further provided with a combination part 9, the specific structure of the combination part 9 can be configured according to actual conditions, and the combination part can be arranged on the side wall or the end face of the storage box 7, so that the use is convenient. For example, in actual use, the removable battery is applied to an electric vehicle, and the removable battery is installed below the electric vehicle seat cushion 10, at this time, the top end surface of the storage box 7 may be fixed to the bottom of the electric vehicle seat cushion 10 through the joint portion 9, and an application schematic diagram of the removable battery based on the structure shown in fig. 10 is shown in fig. 11.
