Description

Battery transfer equipment and charging chamber

technical field

The invention relates to the technical field of battery replacement, in particular to a battery transfer device and a charging chamber.

Background technique

With the popularity of new energy vehicles, the rapid energy replenishment of electric vehicles, including some large commercial vehicles, is an important problem that users hope to solve. Generally speaking, it often takes a long time to replenish the energy of electric vehicles through charging, which is not timely enough for users who are pressed for time. Therefore, more and more users begin to choose to replace the battery pack for energy replenishment. In the battery replacement mode, the battery pack removed from the electric vehicle needs to be sent to the battery rack in the charging room for storage and charging. At the same time, the battery pack that needs to be installed on the electric vehicle is correspondingly obtained from the battery rack.

In order to pick and place the battery pack from the battery rack, a battery transfer device is required to pick and place the battery. Due to the large weight of large commercial vehicles and their heavy load requirements, the battery packs equipped with them are relatively large in size and weight. However, the existing battery transfer equipment does not have enough lifting capacity when transferring battery packs, and the corresponding storage capacity of the battery packs The battery rack cannot be designed to be too high. In this way, the space above the battery rack cannot be reasonably utilized, which leads to the problem of low space utilization of the battery rack.

Contents of the invention

The object of the present invention is to provide a battery transfer device and a charging room to solve the problems of insufficient lifting capacity of the existing battery transfer device, large space occupied by the battery rack, and low space utilization rate of the battery rack.

As shown in Figures 1 to 12, the present invention provides a battery transfer device, including a car 1, an extension mechanism 2, a transmission mechanism 3, a drive mechanism 4 and a counterweight mechanism 5, the extension mechanism 2 is set on the car Inside the car 1, the car 1 can be extended to take and place the battery pack from any position of the battery rack 7; one end of the transmission mechanism 3 is connected to the car 1, and the other end is connected to the counterweight mechanism 5 , the driving mechanism 4 is arranged between the car 1 and the counterweight mechanism 5, and drives the car 1 and the counterweight mechanism 5 to move up and down in reverse by driving the transmission mechanism 3 .

By setting the extension mechanism 2 in the car 1, the extension mechanism 2 extends out of the car 1 to perform the operation of picking and placing the battery pack; and one end of the transmission mechanism 3 It is connected with the car 1, and the other end is connected with the counterweight mechanism 5, and the driving mechanism 4 is arranged between the car 1 and the counterweight mechanism 5, so that the driving device drives The transmission mechanism 3, and then the transmission mechanism 3 drives the car 1 to move up and down, and the setting of the counterweight mechanism 5 can greatly improve the load capacity of the car 1, which is beneficial to battery transfer The equipment transports large battery packs, and the driving mechanism 4 can lift the car 1 with only a small driving force, so that the lifting capacity of the battery transfer equipment is increased, and then the battery pack located in the car 1 can be lifted. To a higher position, to be placed in the battery compartment corresponding to the higher position on the battery rack 7. Such a design enables the battery rack 7 to be set at a higher height, which fully utilizes the height space and improves the utilization rate of the space, so that more battery packs can be placed under the same area, saving space.

In addition, the counterweight mechanism 5 can also make the disposition mechanism descend when the car 1 rises, and the counterweight mechanism 5 rise when the car 1 descends, so that the center of gravity of the battery transfer equipment remains at The middle position avoids that when the car 1 rises, the center of gravity of the battery transfer equipment rises, causing the battery transfer equipment to tilt or even topple over, which improves the stability of the battery transfer equipment.

As a preferred embodiment of the present application, as shown in FIG. 1, the transmission mechanism 3 includes a plurality of transmission assemblies 31, and the two ends of each transmission assembly 31 are respectively connected to an end angle of the car 1 and the Counterweight mechanism 5.

By setting the transmission mechanism 3 to include a plurality of transmission assemblies 31, and the two ends of each transmission assembly 31 are respectively connected to an end angle of the car 1 and the counterweight mechanism 5, so that the transmission mechanism 3 When driving the car 1 up and down, the force can be evenly applied to the car 1, so that the car 1 can rise or fall smoothly, avoiding the transmission assembly 31 set on the car A corner of the car 1 causes the car 1 to be unbalanced when it rises or falls, causing the extension mechanism 2 in the car 1 to tilt, which in turn causes the battery pack to fall, ensuring that the car 1 The stability of car 1 when lifting.

The movement of the weight mechanism 5 remains opposite, thereby keeping the center of gravity of the transfer device at a certain position, further ensuring the stability of the transfer device.

Further, the two sprockets 312 are respectively a first sprocket and a second sprocket, and the first sprocket is arranged corresponding to the end angle and located above the end angle, so that the car 1 and the chain 311 between the first sprocket remain vertical; the second sprocket is connected to the driving mechanism 4, and the driving mechanism 4 drives the second sprocket to rotate so that the The car 1 and the counterweight mechanism 5 move up and down in reverse.

By arranging the first chain 311 corresponding to the end angle and above the end angle, the chain 311 between the car 1 and the first sprocket is maintained in a vertical state, Furthermore, when the driving mechanism 4 drives the car 1 to rotate, the force exerted by the first sprocket on the car 1 is in a vertical upward direction, so as to avoid being located between the car 1 and the first car 1. The chain 311 between the sprockets has a certain angle with the ground, which makes it more laborious to lift the car 1 up and the rising force applied to the car 1 is unstable. On the one hand, it reduces The force required to lift the car 1 reduces the energy required to drive the car 1 up, and on the other hand ensures the stability of the car 1 when it is raised and lowered.

The stability of the movement of the car 1 is improved; at the same time, during the long-term use of the chain 311, due to stress and environmental changes, the length of the chain 311 will change accordingly. At this time, through the elastic The member 52 adjusts the length of the chain 311, so that the length of the chain 311 remains consistent, so that the car 1 is always balanced, which is conducive to improving the stability of the process of picking and placing the battery pack, and avoiding the inconsistency of the length of the chain 311. This causes the car 1 to vibrate when the chain 311 is in motion and the chain 311 cannot be used, which improves the service life of the chain 311 .
