[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] like Figure 1 and Figure 2 The foaming assembly shown includes: at least two foaming plates 1, all of which together form a foaming cavity; the edges of the foaming plates 1 are bent to form a bent portion, and the bent portions of two adjacent foaming plates 1 are arranged in abutment with each other; a sealing structure 2, the sealing structure 2 being arranged in the foaming cavity and covering the two bent portions that are in abutment with each other. The bent portion is provided at the connection of the foaming plates 1, and the two bent portions are arranged in abutment with each other, thereby increasing the path length of the foaming material passing through the gap between the two foaming plates 1 and reducing the leakage of the foaming material. In addition, the sealing structure 2 is provided to cover the two bent portions, so that the foaming material cannot directly enter from the ends of the bent portions, further increasing the leakage path length of the foaming material, improving the sealing effect of the foaming assembly during the foaming process, overcoming the problem of poor sealing effect of the tape sealing in the prior art, effectively ensuring the foaming quality, and when installing the sealing structure 2, the sealing structure 2 can be directly covered on the bent portion, which is simple to operate and improves production efficiency.

[0024] As an embodiment, the sealing structure 2 and the two adjacent foam plates 1 together form a accommodating cavity 3, the bent portions of the two foam plates 1 are both arranged in the accommodating cavity 3, and the accommodating cavity 3 is connected to the foaming cavity. When installing the sealing structure 2, after the bent portions of the two foam plates 1 are attached to each other, the sealing structure 2 is covered on the bent portions, and at the same time, the end surface of the sealing structure 2 facing the foam plate 1 abuts against the corresponding foam plate 1, thereby placing the bent portion into the accommodating cavity 3. During the foaming process, since the foaming cavity is connected to the accommodating cavity 3, part of the foaming material will enter the accommodating cavity 3 to squeeze the two bent portions, thereby reducing the gap between the two bent portions as much as possible, increasing the difficulty of the foaming material leaking from the gap, and ensuring the foaming effect of the foaming component.

[0025] A fitting gap is formed at the connection between the sealing structure 2 and the foaming plate 1, and the accommodating cavity 3 is connected to the foaming cavity through the fitting gap. Since the sealing structure 2 and the foaming plate 1 are not integrally formed, there must be a fitting gap between the two during the abutment and fitting process. Therefore, the fitting gap can be directly used to connect the accommodating cavity 3 and the foaming cavity, which reduces the processing of the sealing structure 2 and / or the foaming plate 1, and also achieves the purpose of reducing the gap between the bent parts of the two, increasing the difficulty of the foaming material leaking from the gap, and ensuring the foaming effect of the foaming component.

[0026] Preferably, the ratio of the width x of the fitting gap to the length d of the bend is in the range of 20% ≤ x / d ≤ 26%. When x / d > 26%, too much foaming material enters the accommodating cavity 3, and the foaming material will still overflow from the gap between the two bends, causing the two foaming sheets 1 to also expand, affecting the foaming quality of the foaming component. When x / d < 20%, too little foaming material enters the accommodating cavity 3, resulting in excessive cavities within the accommodating cavity 3, an unstable structure, and an inability to achieve the purpose of squeezing the two bends.

[0027] As an embodiment, the two bent portions that are bonded to each other include a first bent portion 41 and a second bent portion 42. The first bent portion 41 is bonded to the inner wall of the accommodating cavity 3, and the second bent portion 42 is bonded to the first bent portion 41. The second bent portion 42, the sealing structure 2, and the foam plate 1 together enclose the accommodating cavity 3. At this time, the foaming material entering the accommodating cavity 3 directly squeezes the second bent portion 42. This squeezing force can squeeze both the first and second bent portions 41, 42 toward the inner wall of the accommodating cavity 3. Compared to the case where the foaming material squeezes the first and second bent portions 41, 42 from both sides, the squeezing force can reach a maximum value, and the squeezing effect on the first and second bent portions 41, 42 is also maximized, thereby further improving the sealing effect on the first and second bent portions 41, 42.

[0028] Furthermore, the second bent portion 42 includes a first bonding section 45 and a second bonding section 422. The first bonding section 45 is bonded to the first bent portion 41, and the second bonding section 422 is bonded to the inner wall of the accommodating cavity 3. Since the second bent portion 42 directly bears the pressure of the foaming material, while the first bent portion 41 is bonded to the inner wall of the accommodating cavity 3, the second bonding section 422 is used to separate the foaming material from the first bent portion 41, preventing the foaming material from directly entering the gap between the first bent portion 41 and the inner wall of the accommodating cavity 3 and the gap between the first bent portion 41 and the second bent portion 42, further preventing leakage of the foaming material.

[0029] like Figure 2 As shown, the second bent portion 42 has an L-shaped cross-section. The junction of the first bonding section 45 and the second bonding section 422 forms the vertex of the second bent portion 42. The inner wall of the accommodating cavity 3 includes adjacent first and second side walls. The first bent portion 41 is bonded to the first side wall, and the second bonding section 422 is bonded to the second side wall. The bonding of the second bonding section 422 to the second side wall increases the gap between the first bent portion 41 and the first side wall, as well as the gap between the first bent portion 41 and the second bent portion 42, further preventing leakage of the foaming material.

[0030] The sealing structure 2 is provided with a first sealing section 5 and a second sealing section 6. In two adjacent foaming plates 1, the first sealing section 5 is provided in contact with one foaming plate 1, and the second sealing section 6 is provided in contact with the other foaming plate 1, with a fitting gap being provided between the second sealing section 6 and the foaming plate 1. The first sealing section 5 and the second sealing section 6 are used to enhance the sealing effect between the sealing structure 2 and the corresponding foaming plate 1, making it more difficult for the foaming material to enter the gap between the first bend 41 and the second bend 42, thereby further preventing the foaming material from leaking.

[0031] The foaming assembly further includes a locking member 7, through which the first sealing section 5 is fixed to the foaming plate 1. When installing the sealing structure 2, the first sealing section 5 can be fixed to the foaming plate 1 via the locking member 7, effectively reducing the difficulty of installing the sealing structure 2.

[0032] Similarly, the second sealing section 6 is fixed to the foaming plate 1 through the locking member 7 .

[0033] Preferably, a countersunk hole is provided on the foaming plate 1, and the locking piece 7 is a locking bolt. The head of the locking bolt is located in the countersunk hole, and the other end of the locking bolt protrudes into the foaming cavity and contacts the foaming material. The foaming material is used to squeeze the locking bolt to increase the difficulty of disengaging the locking bolt, thereby improving the locking degree of the locking piece 7 to the sealing structure 2 and the foaming plate 1.

[0034] Moreover, only the gap and the head of the locking bolt can be seen on the appearance of the foam component, and the overall appearance effect is smooth, which improves the appearance of the foam component.

[0035] A heat-insulating structure comprises the above-mentioned foaming component.

[0036] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
