Problems solved by technology

[0003] The quick replacement of the power battery pack can be realized by means of battery replacement equipment at the power station. The quick replacement of the power battery pack relies on the connection method between the power battery pack and the frame. The usual bolt connection obviously cannot meet the needs of quick power battery replacement.

Embodiment 1

[0042] see figure 1 , the embodiment of the present invention provides a bolt-type locking mechanism 3, including a base 31, a locking pin 32 and a torsion spring 33, the base 31 is a fixing part, fixedly installed on the equipment to be locked or the place where the equipment is to be installed, the lock The deadbolt 32 is a movable part, which can move on the base 31 along its axial direction. The torsion spring 33 is used to connect the base 31 and the deadbolt 32 to provide the movement control force for the deadbolt 32 to move to two extreme positions and maintain the lock. The deadbolt is at the extreme position, and the two extreme positions of the deadbolt 32 are respectively corresponding to the locked state and the unlocked state of the bolt-type locking mechanism. The torsion spring 33 has two torsion arms, and the two torsion arms of the torsion spring 33 are connected with the base 31 and the locking bolt 32 respectively. It is rotationally connected with the fir...

Embodiment 2

[0051] Based on the same inventive concept, this embodiment also provides a bolt-type locking mechanism 3, including a base 31, a locking pin 32, and a torsion spring 33. The base 31 is a fixing piece that is fixedly installed on the device to be locked or its installation. On the other hand, the deadbolt 32 is a movable part, which can move on the base 31 along its axial direction, and the torsion spring 33 is used to connect the base 31 and the deadbolt 32 to provide movement control for the deadbolt 32 to move to two limit positions. force and maintain the deadbolt at the extreme position, and the deadbolt 32 moves to two extreme positions corresponding to the locked state and the unlocked state of the bolt-type locking mechanism respectively. The torsion spring 33 has two torsion arms, and the two torsion arms of the torsion spring 33 are connected with the base 31 and the locking bolt 32 respectively. It is rotationally connected with the first torsion arm installation po...

Embodiment 3

[0060] This embodiment provides a new energy vehicle, and the new energy vehicle is not limited to a pure plug-in electric vehicle, a hybrid electric vehicle, an extended-range electric vehicle, and the like. Since this embodiment does not improve the specific structure of the new energy vehicle, but only improves the installation structure of the power battery pack 2 and the frame assembly 1, the structure of the unchanged part of this embodiment can refer to the existing Technology, the specific content will not be explained here.

[0061] see Figure 6 , the power battery pack 2 is installed on the vehicle frame assembly 1, one of the power battery pack 2 and the vehicle frame assembly 1 is provided with a pin seat 21 with a pin hole 211, and the other is provided with the above-mentioned embodiment 1 or The latch type locking mechanism 3 of the second embodiment.

[0062] Specifically, see Figure 7 , in this embodiment, the power battery pack 2 is provided with at leas...

Abstract

The invention discloses a bolt-type locking mechanism, a new energy vehicle and power exchange equipment. The latch type locking mechanism mainly includes three components: a base, a locking pin and a torsion spring. The base is a fixed part, which is fixedly installed on the equipment to be locked or its installation place. The locking pin is a movable part that can be moved along its axial direction. Moving on the base, the torsion spring is used to connect the base and the deadbolt, provide the movement control force for the deadbolt to move to two limit positions and maintain the deadbolt at the limit position, and the two extreme positions of the deadbolt correspond to the deadbolt respectively The locked state and unlocked state of the type locking mechanism. The locking bolt is always in two extreme positions controlled by the torsion spring, that is, the bolt-type locking mechanism is either in the locked state or in the unlocked state, and there will be no intermediate state, which makes the operation of the bolt-type locking mechanism more convenient. It has been significantly improved, which can realize the rapid replacement of the power battery pack of the electric vehicle, has high connection reliability, and has both functions and performance.

Description

technical field [0001] The application belongs to the technical field of new energy vehicles, and in particular relates to a latch type locking mechanism, new energy vehicles and battery replacement equipment. Background technique [0002] The promotion of pure plug-in electric vehicles is affected by reasons such as short driving range and long charging time. If the battery is quickly disassembled after the battery is exhausted, and the pre-charged battery is quickly installed to ensure the continuous operation of the vehicle, it is a new direction for the development of electric vehicles. [0003] The quick replacement of the power battery pack can be realized by means of battery replacement equipment at the swap station. The quick replacement of the power battery pack relies on the connection method between the power battery pack and the frame. The usual bolt connection obviously cannot meet the needs of quick replacement of the power battery. Therefore, it is a technica...
