Description

Technical Field

[0001] The utility model belongs to the technical field of battery charging and battery replacement, and in particular relates to a battery replacement platform compatible with multiple vehicle models. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels but adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures.

[0003] In the battery swap station, the vehicle is parked on the rollers on the battery swap platform. After the vehicle is centered by the centering structure, the RGV cart will drive the locking and unlocking mechanism to move to the bottom of the vehicle, remove the vehicle's battery and replace it. For different models, due to the different positions of the vehicle batteries, the vehicle is often centered by the centering mechanism to ensure that the locking and unlocking mechanism can install and remove the battery. However, for some vehicles, the battery is biased forward or backward relative to the vehicle body, and the RGV cart usually enters the bottom of the vehicle from the left and right sides of the vehicle. This makes it impossible for the locking and unlocking mechanism driven by the RGV cart to successfully replace the battery after the vehicle is centered.

[0004] In order to overcome the above-mentioned defects, technical personnel in this field have actively carried out innovative research in order to create a battery replacement platform mechanism that is compatible with different models of vehicles. Utility Model Content

[0005] The purpose of the present invention is to provide a battery replacement platform that is compatible with a variety of vehicle models to solve the problems raised in the above-mentioned background technology.

With the front direction of the vehicle as the front, the mobile platform slides on the fixed platform and moves in the front and rear directions under the drive of the drive assembly. The fixed platform is fixed with a track 1 for the RGV trolley to travel, and the mobile platform is fixed with a track 2 that can dock with track 1.

[0007] Preferably, the movable platform is provided with at least two groups of rotating wheels parallel in the front-to-back direction, and the fixed platform is provided with wheel grooves for cooperating with the rotating wheels.

[0008] Preferably, the fixed platform includes platform 1 and platform 2, and the platform 1, the mobile platform, and the platform 2 are arranged in sequence from left to right, and wheel grooves are provided on both the platform 1 and the platform 2.

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention. Example

[0024] See Figure 1 A battery swap platform compatible with multiple vehicle models includes a centering mechanism 7, a fixed platform, a mobile platform 3 and a drive assembly 4. With the front direction of the vehicle as the front, the mobile platform 3 slides on the fixed platform and moves in the front and rear directions under the drive of the drive assembly 4. A track 1 5 for the RGV trolley to travel is fixed on the fixed platform, and a track 2 6 capable of docking with the track 1 5 is fixed on the mobile platform 3. The drive assembly 4 can be an electric push rod, a cylinder or other mechanism that can perform linear motion. The centering mechanism is a conventional centering mechanism of a battery swap station and will not be described in detail here.

[0025] The movable platform 3 is provided with at least two sets of parallel running wheels 14 in the front-to-back direction, and the fixed platform is provided with wheel grooves 13 used to cooperate with the running wheels 14 .

[0026] Among them, the fixed platform includes platform 1 and platform 2 2. The platform 1 1, mobile platform 3, and platform 2 2 are arranged in sequence from left to right, and wheel grooves 13 are provided on both platform 1 and platform 2 2.

[0027] The rotating wheel 14 is located on the left and right side walls of the rotating platform, and the wheel groove 13 is set on the right side wall of platform 1 and the left side wall of platform 2 2.

[0028] Among them, the platform 1 and the platform 2 2 are both detachably connected with an inspection cover 8, and the inspection cover 8 is placed above the wheel groove 13 and makes the top surfaces of the platform 1, the mobile platform 3, and the platform 2 2 form a flat plane with a gap less than 10 mm.

[0029] The driving assembly 4 is fixed on a stationary body, and the output end of the driving assembly 4 is hinged on the mobile platform 3. The stationary body can be the ground or a fixed structure fixed on the ground.

[0030] The driving assembly 4 is placed below the mobile platform 3 , and a maintenance cover 9 for inspecting the driving assembly 4 is detachably connected to the mobile platform 3 .

[0031] Among them, the mobile platform 3 is provided with a limit stop 10 at the end of track 2 6 away from track 1 5 to prevent the RGV trolley from leaving track 2 6. Specifically, the bottom surface of the RGV trolley can be a groove wheel, and the limit stop can be a gap on track 2. In this way, when the RGV trolley reaches the gap, the groove wheel will be adjusted into the gap to prevent the RGV trolley from leaving.

[0032] The mobile platform 3 is provided with an in-position sensing block 11 , and the RGV trolley is provided with an induction switch. When the induction switch senses the induction block 11 , the RGV trolley stops.

[0033] A positioning pin hole 12 is provided on the mobile platform 3 , and the RGV trolley is provided with a positioning pin that can be automatically retracted and used in conjunction with the positioning pin hole 12 .

[0034] Working process and principle:

[0035] When in use, the vehicle drives and stops on the battery exchange platform, the centering mechanism centers the vehicle, and the battery exchange platform determines the position of the battery according to the vehicle model. Then the RGV cart drives the unlocking mechanism to run to the determined trajectory in the left and right directions under the vehicle (usually, the position where the induction switch stops when it senses the induction block). Then the driving component drives the RGV cart to move in the front and rear directions of the vehicle, so that the unlocking mechanism is placed under the battery, and then the battery replacement operation can be carried out.

[0036] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
