Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of power batteries, and in particular relates to a side bending device for a battery shell on a cold chain logistics vehicle. Background Art
[0002] With the approach of energy crisis and the improvement of people's environmental awareness, electric vehicles are receiving more and more attention from all walks of life. As the core component of electric vehicles, power batteries have higher and higher requirements for IP (protection level). Now the national standard has stipulated that the IP level of the power battery box of all types of electric vehicles must reach IP67. Therefore, the sealing of the power battery box of the car is very critical. If the sealing performance is poor, not only will it fail to meet the national standard requirements, but the box may also be flooded or dusted, causing problems such as ignition or insulation of the power battery. In severe cases, it may short-circuit and catch fire, endangering the safety of vehicles and people. At present, in order to improve the sealing performance of the power battery shell, the two side walls of the power battery shell will be extended upward for a distance. This section will be bent inward by 90°, so that the extra 2cm connection edge can be placed with a sealing strip and the upper cover for sealing. For the extra 2cm connection edge, the company currently uses a bending machine. Since the power battery shell itself has been formed, it is necessary to redesign the mold if you want to bend it, which is time-consuming and labor-intensive. In addition, the power battery shell is bent before welding. This method requires changing the manufacturing process and is relatively costly. Utility Model Content

Thus, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.
[0015] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fixed connection" and "fixed connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.
[0016] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.
[0017] like Figure 1-Figure 3 As shown, a cold chain logistics vehicle-mounted battery shell side bending device includes a base 1, a battery shell clamping mechanism 2 and a folding mechanism 3. The battery shell clamping mechanism is used to clamp the side of the battery shell. The folding mechanism is installed on the upper part of the battery shell clamping mechanism and is used to bend the connecting edge of the upper part of the battery shell. The battery shell is fixed and limited by the motor shell clamping mechanism, and the upper folding mechanism bends the connecting edge. There is no need to change the existing process, the overall structure is simple, and the cost is low.
[0018] Specifically, the battery shell clamping mechanism includes a side fixing plate 21, a pressing plate 22, a vertical plate 23, a slide rail 24, a connecting plate 25, a guide block 26, a guide wheel 27, a swing plate 28, a motor 29 and a motor bracket 20; the side fixing plate is fixed to one side of the base, the vertical plate is fixed to the other side of the base, the slide rail is vertically installed on the side of the vertical plate, one side of the connecting plate is slidably connected to the slide rail, the pressing plate is fixed to the end of the connecting plate, and the guide block is fixed to the other side of the connecting plate, the guide block has a guide groove, the guide wheel cooperates with the guide groove, the guide wheel is fixed to one end of the swing plate through a connecting shaft, the middle part of the swing plate is connected to the output end of the motor, and the motor is installed on the base through a motor bracket. The motor drives the swing plate to make an arc motion, so that the guide wheel drives the guide block to move up and down, and then the connecting plate moves up and down. Before use, the motor drives the pressing plate to the highest position, and the battery shell is first placed on the base, with one side close to the side fixing plate. The distance between the side fixing plate and the pressing plate should be adjusted in advance according to the width of the battery shell. When the battery shell is placed on the base, the motor will drive the pressing plate to move downward and move the pressing plate to one side of the battery shell. The upper part of the pressing plate is close to the bending position of the connecting edge with the battery shell to facilitate the bending of the connecting edge.
[0019] In this device, the battery shell clamping mechanism includes a clamping cylinder 31 and a clamping strip 32, and the clamping strip is fixed on the piston rod of the clamping cylinder. The clamping strip is located above the pressure plate. The clamping cylinder is fixed to the upper part of the connecting plate through a cylinder bracket 33. The clamping cylinder drives the clamping strip to move, and the clamping strip pushes the connecting edge to gradually bend toward the inside of the battery shell. In order to avoid scratching the connecting edge, one side of the clamping strip is arc-shaped.
[0020] When in use, the power battery shell 4 is prevented from being placed in the battery shell clamping mechanism, with the connecting edge 41 of the battery shell facing upwards. The motor in the battery shell clamping mechanism is started, driving the swing plate to swing, and the swing plate drives the guide wheel to move in the guide block, driving the connecting plate to move up and down on the slide rail, and the pressing plate moves up and down on the side of the battery shell. After the pressing plate is moved to the junction of the battery shell and the connecting edge, the pressing plate stops, and the pressing plate and the side fixing plate on the opposite side clamp the battery shell. The distance between the two can be controlled by adjusting the side fixing plate. After the position of the pressing plate is fixed, the pressing cylinder is started, and the pressing cylinder drives the pressing strip to move, and the pressing strip pushes the connecting edge to bend it 90°, thereby completing the bending work of the side of the battery shell.
[0021] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
