Description

Technical Field

[0002] With the strong support of the state for the new energy field, my country's new energy industry has developed rapidly. As an important part of the new energy field, new energy vehicles have developed by leaps and bounds. When assembling the battery pack, a hoist is often used to lift the battery pack from above to the battery pack frame of the vehicle body. However, the battery pack support frame is often adapted to the size of the battery pack. After the hoist delivers the battery pack to the inside of the vehicle body, the operating space left for the assembler is small, making it difficult to disassemble and extract the hoist. There may even be a jamming phenomenon caused by the interference between the hoist and the battery pack support frame, which greatly affects the assembly efficiency of the battery pack. Utility Model Content

[0003] The present application provides a battery pack mounting mechanism to solve the technical problems of difficult battery pack mounting and low mounting efficiency.

[0004] The technical solution adopted in this application is:

[0005] A battery pack loading mechanism comprises a carrier frame and a battery pack conveying unit mounted on the carrier frame, the battery pack conveying unit having a horizontal conveying surface, the horizontal conveying surface being used to assist the battery pack to be conveyed from the carrier frame to the body of an electric vehicle in a horizontal direction or to assist the battery pack to be conveyed from the body of the electric vehicle to the carrier frame in a horizontal direction, a limit member is mounted on the carrier frame, the limit member is movably arranged to switch between a stop position and an avoidance position; in the stop position, at least a portion of the limit member is higher than the horizontal conveying surface and can stop the battery pack to confine the battery pack to the horizontal conveying surface; in the avoidance position, the limit member is lower than the horizontal conveying surface as a whole to avoid the battery pack.

[0006] The battery pack loading mechanism described in this application also includes the following additional technical features:

[0007] The limiting member includes a movable end movably connected to the supporting frame, and the limiting member can rotate around the movable end to switch between the avoidance position and the stop position.

[0008] It also includes a plug-in component, the support frame is provided with a first limit sleeve, and the limit component is provided with a second limit sleeve aligned with the first limit sleeve. When the limit component is located at the stop position, the plug-in component can be inserted into the first limit sleeve and the second limit sleeve in sequence to connect the limit component with the support frame, thereby fixing the limit component at the stop position.

[0009] The battery pack conveying unit includes a plurality of rolling shafts arranged at intervals, wherein the length direction of the rolling shafts is perpendicular to the forward direction of the battery pack, and the plurality of rolling shafts drive the battery pack to move by rolling.

[0010] The carrier frame includes a first carrier frame and a second carrier frame located on both sides of the battery pack's travel direction, and the first carrier frame and the second carrier frame are connected via a plurality of connecting rods.

[0011] The number of the connecting rods is equal to the number of the rolling shafts. The rolling shafts are provided with through holes penetrating the rolling shafts at the axis positions. The connecting rods are inserted into the through holes so that the rolling shafts can rotate around the connecting rods.

[0012] An anti-slipping member extending in a vertical direction is provided at one end of the carrier away from the limiting member, and the anti-slipping member can prevent the battery pack from slipping out of the horizontal conveying surface.

[0013] The anti-dropping member is fixedly connected to the supporting frame.

[0014] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0015] 1. The battery pack loading mechanism of the present application includes a horizontal conveying surface for conveying the battery pack. When assembling the battery pack, the battery pack only needs to be placed on the horizontal conveying surface. With the assistance of the horizontal conveying surface, the battery pack is conveyed along the side of the vehicle body to the inside of the vehicle body or from the inside of the vehicle body to the carrier. The entire disassembly and assembly process of the battery pack does not require the use of a sling, thereby avoiding interference between the sling and the internal components of the vehicle body, thereby achieving rapid disassembly and assembly of the battery pack. Moreover, since the horizontal conveying surface plays an auxiliary conveying role for the battery pack, there is no need to use a driving device to drive the movement of the battery pack when conveying the battery pack. The disassembly of the battery pack can be achieved only by the operator's push with the assistance of the horizontal conveying surface. The installation and disassembly costs of the battery pack are reduced; in addition, a limiter that can be switched between an avoidance position and a stop position is installed on the carrier of the present application. Taking the installation process of the battery pack as an example, when the battery pack needs to be transported to the interior of the vehicle body, the limiter is adjusted to the avoidance position. At this time, there is no obstruction between the horizontal conveying surface and the interior of the vehicle body, and the battery pack can be transported to the interior of the vehicle body with the assistance of the horizontal conveying surface to achieve the installation of the battery pack. When the battery pack does not need to be transported temporarily, the limiter is adjusted to the stop position. At this time, the limiter acts as a stopper for the battery pack to limit the movement of the battery pack on the horizontal conveying surface, thereby achieving temporary locking of the battery pack and preventing the battery pack from moving toward the direction of the vehicle body and escaping from the horizontal conveying surface.

[0016] 2. As a preferred embodiment of the present invention, the limit member includes a movable end movably connected to the carrier, and the limit member can rotate around the movable end to switch between the avoidance position and the stop position. By providing a movable end and connecting the limit member to the carrier in a rotational connection, the assembler only needs to apply a small force to push the limit member to switch between the stop position and the avoidance position, making the switch of the limit member between the avoidance position and the stop position more flexible, improving the switching speed of the limit member, thereby reducing the time required for the limit member to switch between the stop position and the avoidance position, and improving the working time required for disassembly and assembly of the battery pack, thereby improving the disassembly and assembly efficiency of the battery pack.

[0017] 3. As a preferred embodiment of the present invention, a rolling shaft is provided on the battery pack conveying unit to achieve movement of the battery pack on the horizontal conveying surface in a rolling manner, which helps to reduce the friction resistance between the battery pack and the battery pack conveying unit during movement. Compared with sliding of the battery pack on the horizontal conveying surface or other movement modes, the rolling friction between the battery pack and the battery conveying unit can, on the one hand, reduce the force required for the operator to push the battery pack along the horizontal conveying surface. On the other hand, the rolling friction can reduce the friction damage suffered by the battery pack during movement, which helps to increase the service life of the battery pack.

[0032] like Figure 1As shown, a battery pack loading mechanism comprises a carrier frame 1 and a battery pack conveying unit mounted on the carrier frame 1, wherein the battery pack conveying unit has a horizontal conveying surface, wherein the horizontal conveying surface is used to assist the battery pack to be conveyed from the carrier frame 1 to the body of an electric vehicle in a horizontal direction or to assist the battery pack to be conveyed from the body of an electric vehicle in a horizontal direction to the carrier frame 1, wherein a limit member 3 is mounted on the carrier frame 1, wherein the limit member 3 is movably arranged to switch between a stop position and an avoidance position; in the stop position, at least a portion of the limit member 3 is higher than the horizontal conveying surface and can stop the battery pack to confine the battery pack to the horizontal conveying surface; in the avoidance position, the limit member 3 is lower than the horizontal conveying surface as a whole to avoid the battery pack.

[0033] The battery pack loading mechanism of the present application includes a horizontal conveying surface for conveying the battery pack. When assembling the battery pack, the battery pack only needs to be placed on the horizontal conveying surface, and with the assistance of the horizontal conveying surface, the battery pack is conveyed along the side of the vehicle body to the inside of the vehicle body, or the battery pack is conveyed from the inside of the vehicle body to the carrier 1. The entire disassembly and assembly process of the battery pack does not require the use of a sling, thereby avoiding interference between the sling and the internal components of the vehicle body, thereby achieving rapid disassembly and assembly of the battery pack; moreover, since the horizontal conveying surface plays an auxiliary conveying role for the battery pack, there is no need to use a driving device to drive the movement of the battery pack when conveying the battery pack. The battery pack can be disassembled and assembled only by the operator's push and the assistance of the horizontal conveying surface, reducing The installation and disassembly costs of the battery pack are reduced; in addition, the carrier frame 1 of the present application is equipped with a limit member 3 that can be switched between an avoidance position and a stop position. Taking the installation process of the battery pack as an example, when the battery pack needs to be transported to the interior of the vehicle body, the limit member 3 is adjusted to the avoidance position. At this time, there is no obstruction between the horizontal conveying surface and the interior of the vehicle body, and the battery pack can be transported to the interior of the vehicle body with the assistance of the horizontal conveying surface to achieve the installation of the battery pack. When the battery pack does not need to be transported temporarily, the limit member 3 is adjusted to the stop position. At this time, the limit member 3 acts as a stop for the battery pack to limit the movement of the battery pack on the horizontal conveying surface, thereby achieving temporary locking of the battery pack and preventing the battery pack from moving toward the direction of the vehicle body and escaping from the horizontal conveying surface.

[0034] As a preferred implementation of the present application, Figure 1As shown, the limiter 3 includes a movable end movably connected to the carrier 1, and the limiter 3 can rotate around the movable end to switch between the avoidance position and the stop position. By setting the movable end, the limiter 3 is connected to the carrier 1 in a rotating connection. The assembler only needs to apply a small force to push the limiter 3 to switch between the stop position and the avoidance position, making the switch of the limiter 3 between the avoidance position and the stop position more flexible, improving the switching speed of the limiter 3, thereby reducing the time required for the limiter 3 to switch between the stop position and the avoidance position, and improving the working time required for disassembly and assembly of the battery pack, thereby improving the disassembly and assembly efficiency of the battery pack.

[0035] The present application does not limit the connection method between the limit member 3 and the carrier frame 1. It can also be that a plug-in slot is set on the carrier frame 1, and a plug-in protrusion adapted to the plug-in slot is set on the limit member 3. The limit member 3 is plugged into the carrier frame 1 through the cooperation of the plug-in protrusion and the plug-in slot so that the limit member 3 is located in the stop position, and the plug-in protrusion is pulled out from the plug-in slot so that the limit member 3 is located in the avoidance position.

[0036] As a preferred embodiment of this implementation, Figure 1 As shown, it also includes a plug-in connector, the carrier 1 is provided with a first limiting sleeve 4, the limiting member 3 is provided with a second limiting sleeve 5 aligned with the first limiting sleeve 4, and when the limiting member 3 is located at the stop position, the plug-in connector can be inserted into the first limiting sleeve 4 and the second limiting sleeve 5 in sequence to connect the limiting member 3 with the carrier 1, thereby fixing the limiting member 3 at the stop position. By providing the plug-in connector, the first limiting sleeve 4 and the second limiting sleeve 5, when the limiting member 3 is located at the stop position, the locking of the limiting member 3 can be achieved by only inserting the plug-in connector into the first limiting sleeve 4 and the second limiting sleeve 5 in sequence, thereby preventing the limiting member 3 from moving from the stop position to the avoidance position under the action of external force, thereby providing a guarantee for limiting the movement of the battery pack. The present embodiment does not limit the locking method of the limit member 3 in the stop position. It can also be that a first magnetic member is arranged on the carrier 1, and a second magnetic member with opposite magnetic properties to the first magnetic member is arranged on the limit member 3. When the limit member 3 is located at the stop position, the limit member 3 is locked in the stop position through the magnetic attraction cooperation between the first magnetic member and the second magnetic member.

By arranging the rolling shafts 6 on the battery pack conveying unit, the movement of the battery pack on the horizontal conveying surface is realized in a rolling manner, which helps to reduce the friction resistance between the battery pack and the battery pack conveying unit during the movement. Compared with the sliding or other movement modes of the battery pack on the horizontal conveying surface, the rolling friction mode between the battery pack and the battery conveying unit can reduce the force required by the operator to push the battery pack along the horizontal conveying surface. On the other hand, the rolling friction can reduce the friction damage suffered by the battery pack during the movement, which helps to increase the service life of the battery pack.

The rolling shafts 6 are arranged to rotate around the connecting rods 13 to assist the battery pack to move forward, so that the connecting rods 13 not only have the function of connecting the first carrier frame 11 and the first carrier frame 12 to form the carrier frame 1, but also integrate the function of rotating the rolling shafts 6, the functions are further integrated, and the structural design of the carrier frame 1 is optimized.

[0042] As a preferred embodiment of the present application, Figure 1 As shown, an anti-slipping member 2 extending in the vertical direction is provided at one end of the carrier 1 away from the limiting member 3, and the anti-slipping member 2 can prevent the battery pack from slipping off the horizontal conveying surface. By providing the anti-slipping member 2, when the battery pack is removed from the vehicle body, the battery pack will stop moving on the horizontal conveying surface when it moves away from the vehicle body and reaches the end of the carrier 1, thereby preventing the battery pack from slipping off from the horizontal conveying surface due to excessive movement.

[0043] As a preferred embodiment of this embodiment, the anti-dropping member 2 is fixedly connected to the carrier frame 1. The anti-dropping member 2 is arranged to be fixedly connected to the carrier frame 1, which can improve the connection strength between the anti-dropping member 2 and the carrier frame 1, so as to improve the service life of the carrier frame 1. This embodiment does not limit the fixed connection method of the anti-dropping member 2 and the carrier frame 1, and the anti-dropping member 2 can be connected to the carrier frame 1 by welding or integral molding.
