Description

Technical Field

[0001] The utility model relates to the technical field of back glue, and more specifically, to a spliced back glue structure. Background Art

[0002] With the rapid development of new energy technologies, especially the widespread popularity of electric vehicles, energy storage devices, and portable electronic products, the core energy storage unit of these devices, the battery cell, has become the focus of attention in the industry. The fixing and protection mechanisms of battery cells are directly related to the performance, service life, and user safety experience of the overall device.

[0003] Traditional battery cell fixing methods mainly include two types: the whole-piece back glue and the stamping-shaped back glue. When using the whole-piece back glue, it needs to be pasted on one battery cell first, and then fixed with another battery cell. Although it can provide a strong fixing effect, its production cost is relatively high, and a large pre-pressure is often required during the production process to ensure the tight fit between the battery cell and the back glue or between battery cells. However, this excessive pre-pressure sometimes exceeds the tolerance of the battery cell, causing unnecessary damage to the battery cell and affecting its performance and service life.

[0004] On the other hand, although the stamping-shaped back glue structure solves the problem of excessive pre-pressure to a certain extent and can meet the basic requirements for battery cell fixing, its cost has not been significantly improved.

[0005] Therefore, it is necessary to design a more economical back glue structure to reduce the usage cost. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a spliced back glue structure, which avoids unnecessary material waste through the spliced design, thereby reducing the production cost.

[0007] A spliced back glue structure includes two first glue strips and two second glue strips spliced into a frame body. The first glue strip is provided with a first splicing part that extends outward from two wide sides of the first glue strip, and the second glue strip is provided with a second splicing part that is recessed inward from one of the long sides of the second glue strip. The first splicing part is spliced with the second splicing part to connect the first glue strip and the second glue strip.

[0008] In the above technical solution, two first adhesive strips and two second adhesive strips form a complete frame through a specific splicing method. Compared with the traditional whole-piece back adhesive or the stamping-shaped back adhesive, the splicing-type back adhesive structure of the present utility model is more economical in material use. By calculating the length and quantity of the required adhesive strips, unnecessary material waste can be avoided, thereby reducing production costs. The first adhesive strip is provided with a first splicing portion, and the first splicing portion extends outward from the two wide sides of the first adhesive strip, increasing the surface area of the first adhesive strip, thereby enhancing the stability and firmness when splicing with the second adhesive strip. Corresponding to the first adhesive strip, the second adhesive strip is provided with a second splicing portion, and the second splicing portion is recessed inward from one of the long sides of the second adhesive strip, so that the second splicing portion can closely cooperate with the first splicing portion to form a tight connection. At the same time, due to the existence of the recessed part, the stability and accuracy of the first adhesive strip and the second adhesive strip during splicing are also increased. During assembly, the first splicing portion of the first adhesive strip is spliced with the second splicing portion of the second adhesive strip. Due to the outward extension of the first splicing portion and the inward recess design of the second splicing portion, the two can be perfectly fitted together to form a stable connection. This splicing method is not only simple and convenient, but also can ensure the overall strength and stability of the back adhesive structure. The present utility model avoids unnecessary material waste through the splicing design, thereby reducing production costs.

[0009] Further, the first splicing portion includes a first boss and a second boss that are interconnected, and the second splicing portion includes a first groove and a second groove that are interconnected, and the first boss and the second boss are respectively inserted into the first groove and the second groove.

[0010] In the above technical solution, the first boss and the second boss are respectively inserted into the first groove and the second groove to form a tight fitting structure. This design greatly increases the contact area between the first adhesive strip and the second adhesive strip, making the connection tighter and more stable. When subjected to external forces, this fitting structure can more effectively disperse and resist external forces, preventing the joint from loosening or breaking.

[0011] Further, the size of the first boss and the size of the second boss are respectively adapted to the size of the first groove and the size of the second groove.

[0012] In the above technical solution, the first boss and the second boss are adapted to the size of the first groove and the second groove, ensuring that a tight fit can be formed between them. This tight fit not only enhances the stability of the connection, but also reduces the gap at the joint, thereby improving the overall sealing performance and dust and water resistance.

[0013] Further, the first boss and the second boss are vertically arranged to form a "T" shape, and the first groove and the second groove are vertically arranged to form a "T" shape.

[0014] In the above technical solution, the "T" - shaped design has stronger stability and supporting force in structure. The first boss and the second boss are vertically arranged, so that the connection points can be effectively supported in multiple directions, thereby enhancing the stability of the entire adhesive structure. Similarly, the "T" - shaped design of the first groove and the second groove also provides a more stable receiving structure for the insertion of the first boss and the second boss, preventing the first boss and the second boss from shifting or coming out when stressed.

[0015] Furthermore, the first boss is vertically arranged with the second boss to form an "L" shape, and the first groove is vertically arranged with the second groove to form an "L" shape.

[0016] In the above technical solution, the "L" - shaped design has certain advantages in structural mechanics, especially when two perpendicular bosses or grooves are combined. This design enables the connection points to disperse and absorb forces from different directions, thereby enhancing the strength of the entire adhesive structure. In application scenarios where large lateral forces or torsional forces need to be borne, this design is particularly effective.

[0017] Furthermore, the frame is rectangular.

[0018] In the above technical solution, as one of the basic geometric shapes, the rectangle has good stability and load - bearing capacity. In the spliced adhesive structure, the rectangular frame can more effectively disperse and resist external forces from all directions, ensuring the stability of the entire structure. This stability is particularly important in application scenarios where a certain weight or pressure needs to be borne.

[0019] Furthermore, the frame is square.

[0020] In the above technical solution, as a geometric shape with equal - length four sides, the square has high symmetry. This symmetry not only makes the square frame more harmonious and unified visually, but also enables it to distribute forces evenly when stressed, enhancing the stability and balance of the structure.

[0021] Furthermore, the materials of the first adhesive strip and the second adhesive strip are both silicone.

[0022] In the above technical solution, the silicone material has excellent high - temperature resistance and can maintain stable physical and chemical properties in high - temperature environments. This is particularly important for the cell fixing structure that needs to work under high - temperature conditions, such as the battery pack in an electric vehicle.

[0023] Compared with the prior art, the beneficial effects of the present utility model are as follows: By designing two first adhesive strips and two second adhesive strips to form a frame body by splicing, compared with the traditional integral adhesive backing or the square-shaped adhesive backing, the spliced adhesive backing structure is more economical in material use. By calculating the length and quantity of the required adhesive strips, unnecessary material waste can be avoided, thereby reducing production costs. During the splicing process, first align the first splicing portion on the first adhesive strip with the second splicing portion on the second adhesive strip. At this time, the first adhesive strip and the second adhesive strip are firmly spliced through the close cooperation of the first splicing portion and the second splicing portion. Due to the mutual locking effect between the first splicing portion and the second splicing portion, the spliced frame body has high structural strength and stability and can withstand a certain amount of external force and deformation.

[0031] The spliced adhesive backing structure of the present utility model will be further described in detail below in conjunction with specific embodiments and the accompanying drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0032] Please refer to Figure 1 and Figure 2, in a preferred embodiment, the splicing type adhesive structure of the present utility model comprises two first adhesive strips 1 and two second adhesive strips 2 spliced into a frame body. The first adhesive strip 1 is provided with a first splicing portion 101 which extends outward from the two wide sides of the first adhesive strip 1. The second adhesive strip 2 is provided with a second splicing portion 201 which is recessed inward from one of the long sides of the second adhesive strip 2. The first splicing portion 101 is spliced with the second splicing portion 201 so as to connect the first adhesive strip 1 and the second adhesive strip 2.

[0033] In the actual application process of the above structure, the two first adhesive strips 1 and the two second adhesive strips 2 form a complete frame body through a specific splicing method. Compared with the traditional whole-piece adhesive or stamping-shaped adhesive, the splicing type adhesive structure of the present utility model is more economical in material use. By calculating the length and quantity of the required adhesive strips, unnecessary material waste can be avoided, thereby reducing the production cost. The first adhesive strip 1 is provided with a first splicing portion 101 which extends outward from the two wide sides of the first adhesive strip 1, increasing the surface area of the first adhesive strip 1, thus enhancing the stability and firmness when splicing with the second adhesive strip 2. Corresponding to the first adhesive strip 1, the second adhesive strip 2 is provided with a second splicing portion 201 which is recessed inward from one of the long sides of the second adhesive strip 2, enabling the second splicing portion 201 to closely cooperate with the first splicing portion 101 to form a tight connection. At the same time, due to the existence of the recessed part, the stability and accuracy of the first adhesive strip 1 and the second adhesive strip 2 during splicing are also increased. During assembly, the first splicing portion 101 of the first adhesive strip 1 is spliced with the second splicing portion 201 of the second adhesive strip 2. Due to the outward extension of the first splicing portion 101 and the inward recess design of the second splicing portion 201, the two can be perfectly fitted together to form a stable connection. This splicing method is not only simple and convenient, but also can ensure the overall strength and stability of the adhesive structure. The present utility model meets the industry's demand for reducing production costs through the splicing design.

[0034] In this embodiment, the first splicing portion 101 includes a first boss 1011 and a second boss 1012 that are in communication with each other. The second splicing portion 201 includes a first groove 2011 and a second groove 2012 that are in communication with each other. The first boss 1011 and the second boss 1012 are respectively inserted into the first groove 2011 and the second groove 2012. The first boss 1011 and the second boss 1012 are respectively inserted into the first groove 2011 and the second groove 2012, forming a tight fitting structure. This design greatly increases the contact area between the first rubber strip 1 and the second rubber strip 2, making the connection tighter and more stable. When subjected to external forces, this fitting structure can more effectively disperse and resist the external forces, preventing the joint from loosening or breaking. The design of the communicating boss and groove provides a clear guiding and positioning function. During the splicing process, users can quickly and accurately complete the splicing by observing the positional relationship between the boss and the groove. This design reduces the errors and deviations during the splicing process and improves the positioning accuracy.

[0035] Specifically, the dimensions of the first boss 1011 and the second boss 1012 are respectively adapted to the dimensions of the first groove 2011 and the second groove 2012. The dimensions of the first boss 1011 and the second boss 1012 being adapted to the dimensions of the first groove 2011 and the second groove 2012 ensure that a tight fit can be formed between them. This tight fit not only enhances the stability of the connection but also reduces the gap at the joint, thereby improving the overall sealing and dust and water resistance capabilities. Due to the adaptation of the dimensions of the boss and the groove, the connection between them is tighter and more secure. This tight connection helps to disperse and resist external forces, preventing the structure from loosening or falling off when subjected to impact or vibration. Therefore, this design enhances the stability and reliability of the back glue structure and extends its service life.

[0036] In one embodiment, please refer to Figure 3, the first boss 1011 and the second boss 1012 are perpendicularly arranged to form a "T" shape, and the first groove 2011 and the second groove 2012 are perpendicularly arranged to form a "T" shape. The "T" shape design has stronger stability and support force in terms of structure. The perpendicular arrangement of the first boss 1011 and the second boss 1012 enables the connection points to be effectively supported in multiple directions, thereby enhancing the stability of the entire adhesive structure on the back. Similarly, the "T" shape design of the first groove 2011 and the second groove 2012 also provides a more stable receiving structure for the insertion of the first boss 1011 and the second boss 1012, preventing the first boss 1011 and the second boss 1012 from shifting or coming out when stressed. The bosses and grooves with the "T" shape design have more definite orientation when being spliced. Users can quickly and accurately find the splicing points according to the shape and position of the "T" shape, and insert the bosses into the corresponding grooves. This design reduces the errors and deviations during the splicing process, and improves the positioning accuracy and splicing efficiency.

[0037] In another embodiment, please refer to Figure 4 , the first boss 1011 and the second boss 1012 are perpendicularly arranged to form an "L" shape, and the first groove 2011 and the second groove 2012 are perpendicularly arranged to form an "L" shape. The "L" shape design has certain advantages in structural mechanics, especially when two perpendicular bosses or grooves are combined together. This design enables the connection points to disperse and absorb forces from different directions, thereby enhancing the strength of the entire adhesive structure on the back. In application scenarios where large lateral forces or torsional forces need to be borne, this design is particularly effective. Since the first boss 1011 and the second boss 1012 as well as the first groove 2011 and the second groove 2012 all form an "L" shape, they can form a more stable locking effect when connected. This locking effect can prevent relative displacement or loosening of the connection part when stressed, thereby improving the stability of the connection.

[0038] In one implementation, the frame body is rectangular. As one of the basic geometric shapes, the rectangle has good stability and load-bearing capacity. In the spliced adhesive structure on the back, the rectangular frame body can more effectively disperse and resist external forces from all directions, ensuring the stability of the entire structure. This stability is particularly important in application scenarios where a certain weight or pressure needs to be borne.

[0039] In another embodiment, the frame body is square. As a geometric shape with four equal sides, the square has high symmetry. This symmetry not only makes the square frame body more harmonious and unified visually, but also enables it to distribute forces evenly when stressed, enhancing the stability and balance of the structure.

[0040] It should be noted that the materials of the first rubber strip 1 and the second rubber strip 2 are both silica gel. The silica gel material has excellent high-temperature resistance and can maintain stable physical and chemical properties in a high-temperature environment. This is particularly important for the cell fixing structure that needs to work under high-temperature conditions, such as the battery pack in an electric vehicle. At the same time, silica gel is also an excellent electrical insulating material and can effectively isolate current and electric fields. In the cell fixing and protection, this characteristic helps to prevent short circuits and leakage between cells or between cells and the external circuit, improving the safety of the battery system.
