Description

Technical Field

[0001] The utility model relates to a blister box, in particular to a power battery sealed foam blister box. Background Art

[0002] Foam can provide insulation, buffering, flame retardancy, sealing, support, shock absorption and other functions in the power battery pack. When the battery cell expands and contracts due to heat, the foam can play a role of insulation and buffering; when the battery cell has thermal runaway, the foam can prevent the transfer of heat and has flame retardant properties; in the battery pack, located below the liquid cooling plate or next to the upper and lower box covers, the foam can play a supporting and shock absorbing role, and can also be used as a battery sealing ring. Due to the diversity of the shapes of the foam pads and the soft and easy deformation of the foam material, it is difficult to assemble on the production line. Therefore, a load-bearing foam blister box is designed to solve the above problems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a power battery sealed foam blister box, which is light and thin, low in cost, easy to assemble, stackable, recyclable and highly practical.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a power battery sealed foam blister box, including a blister box body, a first foam pad position, a second foam pad position, a foam pad limiting slot, an anti-fool angle and a stacking support position. The blister box body is provided with a first foam pad position and a second foam pad position for placing the foam pad, the middle and both sides of the first foam pad position and the second foam pad position are provided with foam pad limiting slots, a corner of the blister box body is provided with an anti-fool angle, and stacking support positions are provided around the blister box body.

[0005] Preferably, the blister box body is a PS blister box.

[0006] Preferably, a single-side gap of 0.3 mm is reserved between the foam pad limiting slot and the foam pad position.

[0007] Preferably, the stacking support position adopts a negative draft structure.

[0008] The beneficial effects of the utility model are as follows: the blister box of the utility model has reasonable structural design, light and thin texture, low cost, easy assembly, stackability, recyclability and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods;

[0010] Figure 1 It is a schematic diagram of the structure of the utility model;

[0011] Figure 2It is a stacking schematic diagram of the utility model. DETAILED DESCRIPTION

[0012] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0013] Reference Figure 1-2 The present specific implementation adopts the following technical scheme: a power battery sealed foam blister box, comprising a blister box body 1, a first foam pad position 2, a second foam pad position 3, a foam pad limiting slot 4, an anti-fool angle 5 and a stacking support position 6. The blister box body 1 is provided with a first foam pad position 2 and a second foam pad position 3 for placing foam pads. Foam pad limiting slots 4 are provided in the middle and on both sides of the first foam pad position 2 and the second foam pad position 3. The foam pads are embedded in the foam pad limiting slots. An anti-fool angle 5 is provided at one corner of the blister box body 1, and stacking support positions 6 are provided around the blister box body 1.

[0014] It is worth noting that the blister box body 1 is a PS blister box.

[0015] It is worth noting that a single-side gap of 0.3 mm is reserved between the foam pad limiting slot 4 and the foam pad.

[0016] In addition, the stacking support position 6 adopts a negative draft structure.

[0017] The blister box of this specific embodiment is made of heat-resistant and aging-resistant PS material through a blister process. The blister box after molding is light and thin, and has low cost. A sealed foam card slot is provided on the blister tray according to the shape of the foam pad, and a single-side gap of 0.3 is reserved between the card slot and the foam pad to facilitate suction and assembly; the blister tray is provided with an anti-fool bevel to prevent reverse installation on the tray line, and the outer periphery of the blister tray is provided with a support buckle with a negative draft design, which can be stacked and recycled.

[0018] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
