Description

Technical Field

[0001] The utility model relates to the technical field of brake light sensor installation, and more specifically, to a glue sealing and overflowing structure of a brake light sensor. Background Art

[0002] With increasingly fierce competition in the brake light sensor market, performance (sealing) and manufacturing costs are crucial. Improving performance (sealing) and reducing manufacturing costs are currently the primary challenges facing manufacturers. The significant increase in brake light sensor production is driving higher demands on performance (sealing) and manufacturing costs.

[0003] To protect the internal electronic components of the brake light sensor, the PCBA needs to be sealed to reduce damage from moisture or physical impact. Therefore, adding a waterproof sealing design to the brake light is indispensable. To meet the sealing protection performance requirements, most of the solutions on the market use covers and shells, which are connected by ultrasonic welding. However, the welding sealing stability is not enough, which can easily damage the shell or cover, causing waste and easily producing defective products. The second method is to use epoxy resin glue to completely cover the PCBA part to achieve a sealing and waterproof effect. However, due to the poor fluidity of the sealant, the curing time is long, and it needs to be placed in an oven at a specific temperature to cure. Therefore, the glue-filled surface can only rely on its own leveling and is difficult to control with a jig. As a result, there is often too much glue protruding from the product surface, affecting product installation, or too little glue to meet the waterproof performance. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a glue sealing and overflowing structure for a brake light sensor.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the glue sealing and overflow structure of the brake light sensor includes: a glue potting layer and a protective layer, and the glue potting layer and the protective layer are both fixed on the upper side of the mounting plate; a mounting platform is provided at the lower part of the mounting plate, and a plurality of brake light sensor bodies are provided on the upper part of the mounting plate, and the brake light sensor bodies are vertically plugged into the mounting plate, and the brake light sensor bodies are correspondingly arranged directly above the mounting platform; the glue potting layer and the protective layer are both arranged in an annular structure, and the glue potting layer is arranged on the inner side of the protective layer, and an annular glue overflow groove is formed between the glue potting layer and the protective layer; the upper surface of the glue potting layer is lower than the upper surface of the protective layer.

[0006] As a preferred technical solution of the present invention, several groups of separation strips are provided between the glue filling layer and the protective layer, and the separation strips divide the glue overflow groove into several groups of glue overflow cavities; the top of the separation strips is flush with the glue filling layer.

[0007] As a preferred technical solution of the present invention, the dividing strip is provided with convection holes, the convection holes are provided in the middle of the dividing strip, and the convection holes are provided as square through holes.

[0008] As a preferred technical solution of the present invention, a plurality of groups of notches are provided on the upper portion of the glue-filling layer. The notches are spaced apart from the separating strips, the cross-section of the notches is square, and a chamfered structure is provided on the top of the notches.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention sets the glue filling layer and the protective layer to different heights, and the upper surface of the glue filling layer is lower than the upper surface of the protective layer.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] like Figures 1 to 2As shown, the utility model provides a glue sealing and overflow structure for a brake light sensor, comprising: a glue potting layer 1 and a protective layer 2, wherein the glue potting layer 1 and the protective layer 2 are both fixed on the upper side of a mounting plate 3; a mounting platform 9 is provided at the lower portion of the mounting plate 3, and a plurality of brake light sensor bodies 8 are provided on the upper portion of the mounting plate 3, wherein the brake light sensor bodies 8 are vertically plugged into the mounting plate 3, and the brake light sensor bodies 8 are correspondingly arranged directly above the mounting platform 9; the glue potting layer 1 and the protective layer 2 are both arranged in an annular structure, and the glue potting layer 1 is arranged on the inner side of the protective layer 2, and an annular glue overflow groove 5 is formed between the glue potting layer 1 and the protective layer 2; the upper surface of the glue potting layer 1 is lower than the upper surface of the protective layer 2.

[0016] The glue layer 1 and the protective layer 2 are fixed to the mounting plate 3. The space inside the glue layer 1 is used to set the brake light sensor body 8, which is arranged opposite the mounting platform 9. Glue is poured into the space inside the glue layer 1 to fix the brake light sensor body 8. A height difference is set between the upper surfaces of the glue layer 1 and the protective layer 2. The top of the inner glue layer 1 is lower than the top of the outer protective layer 2. In this way, when the glue expands due to high-temperature curing, the overflowed glue will flow into the overflow groove 5 between the glue layer 1 and the protective layer 2 and accumulate in the overflow groove 5. Because the upper surface of the outer protective layer 2 is higher, the water cannot overflow to the outside. In this way, the amount of glue is sufficient and the overflow of glue will not affect the use of the product.

[0017] Among them, several groups of separation strips 4 are provided between the glue filling layer 1 and the protective layer 2 , and the separation strips 4 divide the glue overflow groove 5 into several groups of glue overflow cavities; the top of the separation strips 4 is flush with the glue filling layer 1 .

[0018] The provision of the separation strip 4 can increase the structural strength between the glue-filling layer 1 and the protective layer 2, which is beneficial to maintaining the stability of the overall structure.

[0019] The dividing strip 4 is provided with convection holes 7 , which are arranged in the middle of the dividing strip 4 and are square through holes.

[0020] The convection holes 7 are provided to facilitate the mutual flow of glue in the glue overflow groove 5 , thereby maintaining the level of the glue in the glue overflow groove 5 .

[0021] Among them, a plurality of groups of notches 6 are provided on the upper part of the glue-filling layer 1 . The notches 6 are spaced apart from the separating strips 4 . The cross section of the notches 6 is square, and a chamfered structure is provided on the top of the notches 6 .

[0022] The provision of the notch 6 makes it easier for the glue to flow out into the glue overflow groove 5 .

[0023] The mounting plate 3 is provided with crisscross reinforcing ribs, and two groups of bosses are provided on the mounting plate 3, and the two groups of bosses are respectively provided corresponding to the two groups of mounting platforms 9; the brake light sensor body 8 is distributed in a rectangular array on the bosses.

[0024] The reinforcing ribs can increase the structural strength of the entire mounting plate 3 , and the brake light sensor body 8 is correspondingly plugged into the mounting platform 9 on the boss for use.
