Description

Technical Field

[0001] The utility model relates to the technical field of automobile handles, in particular to a glue-filling installation structure of a handle. Background Art

[0002] The glue-filled installation structure of automobile handles is an installation method that uses adhesives or sealants to fix the handles to the car doors or other parts. This structure is widely used in automobile manufacturing and maintenance because it can provide strong fixing force and good waterproof and dustproof effects.

[0003] In the existing glue-filling installation structure of the handle, the entire welding plate will be filled with glue, which will consume a large amount of colloid material. When a large amount of glue is poured, the colloid solidifies relatively slowly, so that the production process requires more time. Too much colloid material increases the weight of the handle, making the entire structure more cumbersome, which is not conducive to the user experience. Too much colloid material may affect the heat dissipation effect of the electronic components, causing the electronic components to overheat, affecting their performance and lifespan. At the same time, the heat generated by the electronics can easily cause the soft glue to bulge, affecting the user's touch feel and even causing the handle to fail. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a glue injection installation structure for a handle, which not only saves colloid material but also reduces unnecessary weight by limiting the glue injection area, while allowing the colloid to solidify quickly to provide sufficient fixing force and sealing effect.

[0005] In order to solve the above technical problems, the utility model provides a glue filling and installation structure of a handle, including a frame, a concave cavity is provided in the frame, a welding plate is provided on the concave cavity, a PCB board is provided on the welding board, electronic components are provided on the PCB board, first baffles are provided on both sides of the PCB board, a first glue filling chamber for filling colloid is provided between the first baffles, a second baffle is provided on one side of the concave cavity, and a second glue filling chamber is formed between the second baffle and the welding plate.

[0006] The welding plate is provided with a side plate extending toward the concave cavity, the side plate is connected to the frame, and the first glue pouring chamber is formed between the first baffle plate and the side plate.

[0007] The welding plate is provided with through holes.

[0008] A breathing membrane is arranged on the through hole.

[0009] The PCB board is connected with a wire, and the first baffle is provided with a corresponding groove.

[0010] A conductor fixing chamber is provided on one side of the second glue pouring chamber.

[0011] A sealing plug is arranged in the wire fixing chamber.

[0012] Polyurethane potting glue is poured into the first glue pouring chamber and the second glue pouring chamber.

[0013] The side panels and the frame are welded by laser.

[0014] The frame is also provided with soft glue, and the soft glue and the frame are double-color injection molded.

[0015] When the utility model is used, first install the PCB board on the welding board to ensure that it is tightly combined with the welding board, install the electronic components on the PCB board, and connect the corresponding wires, and install the first baffle on both sides of the PCB board to form a first glue filling chamber with the side plates of the welding board. The wires are arranged through the corresponding grooves on the first baffle and fixed in the second baffle on one side of the cavity. Polyurethane potting glue is poured into the first glue filling chamber to make it evenly distributed and solidified to provide additional fixing force and sealing effect. Polyurethane potting glue is also poured into the second glue filling chamber to fix and protect the wires, and the welding plate is placed in the cavity of the skeleton to ensure that it is correctly positioned. The side plate is fixed to the skeleton by laser welding to ensure that the welding plate is firmly connected to the skeleton. A breathing membrane is installed at the through hole on the welding plate to ensure pressure balance inside and outside the chamber to prevent the soft glue from bulging due to temperature changes and affecting the user's touch feel.

[0016] The beneficial effects brought by the utility model are:

[0017] The utility model limits the glue injection area, and does not need to inject glue into the entire welding plate, which not only saves colloid material, but also reduces unnecessary weight, and at the same time makes the colloid solidify quickly, providing sufficient fixing force and sealing effect.

[0018] The breathing membrane effectively balances the pressure inside and outside the chamber, preventing the pressure difference inside and outside caused by temperature changes from causing the soft rubber to bulge.

[0019] The utility model has a stable structure, and through laser welding and two-color injection molding processes, as well as excellent material properties, the stability of the overall structure is ensured to prevent loosening and deformation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0028] according to Figure 1 , Figure 3 and Figure 4 As shown, a glue filling and installation structure of a handle of the utility model comprises a frame 1, a cavity 2 is provided in the frame 1, a welding plate 3 is provided on the inner surface of the cavity 2, the welding plate 3 is used as a supporting structure and is firmly fixed in the cavity 2, a PCB board 4 is installed on the welding plate 3, the PCB board 4 is the electronic control core of the whole structure, electronic components 5 are installed on the PCB board 4, these electronic components 5 are responsible for detecting the operation of the handle and transmitting the signal to the control system to realize intelligent control, and first baffles 6 are provided on both sides of the PCB board 4, these first baffles 6 not only play the role of supporting and protecting the PCB board 4, but also form a first glue filling chamber 7 between the first baffles 6. The first glue filling chamber 7 enables the colloid to be evenly distributed and quickly solidified in a limited area, without the need to fill the entire welding plate 3 with glue, and in addition, the colloid also has a sealing effect, which can effectively prevent moisture and dust from entering and protect the internal electronic components and structures.

[0029] The welding plate 3 is provided with a side plate 8 extending toward the concave cavity 2, and the side plate 8 is fixed to the frame 1 by laser welding. Laser welding ensures that the side plate 8 is firmly combined with the frame 1 to prevent loosening and deformation. On this basis, a closed first glue pouring chamber 7 is formed between the first baffle plate 6 and the side plate 8.

[0030] The welding plate 3 is also provided with a through hole 9, and the through hole 9 is covered with a breathing film 10. Since the electronic components generate heat during operation, the soft glue 17 may bulge and expand, affecting the user's touch feeling and may even cause the handle to fail. In order to solve this problem, a breathing film 10 is provided. The breathing film 10 can allow air and water vapor to pass through, but prevent liquid water and dust from entering, thereby effectively balancing the pressure inside and outside the chamber.

A wire fixing chamber 15 is provided on one side of the second glue pouring chamber 14, and glue is also poured in the wire fixing chamber 15 at the same time, which further improves the reliability and durability of the entire installation structure.

[0032] The first glue pouring chamber 7 and the second glue pouring chamber 14 are filled with polyurethane potting glue. Compared with ordinary plastic low-pressure injection molding sealing glue materials, polyurethane potting glue has excellent adhesion and can be firmly attached to the surfaces of various materials, including metal, plastic and glass, to ensure a strong connection between components. Its excellent durability and mechanical properties enable it to remain stable in various harsh environments and extend the service life of the product. Polyurethane potting glue also has good elasticity and can effectively absorb and buffer mechanical vibrations and shocks, reducing the stress and damage risks of electronic components during use. In addition, it has high tolerance to a variety of chemicals and provides effective protection in chemically corrosive environments. Its excellent electrical insulation properties prevent electrical short circuits and other failures, ensuring the safe operation of electronic components.

[0033] The skeleton 1 is also provided with soft glue 17, which provides a comfortable touch and anti-slip function for the handle. The soft glue 17 and the skeleton 1 are two-color injection molded.

The polyurethane potting glue is also poured into the second glue filling chamber 14 to fix and protect the wire 11, and the welding board 3 is placed in the cavity 2 of the skeleton 1 to ensure that it is in the correct position. The side plate 8 is fixed to the skeleton 1 by laser welding to ensure that the welding board 3 is firmly connected to the skeleton 1. A breathing membrane 10 is installed at the through hole 9 on the welding board 3 to ensure that the pressure inside and outside the chamber is balanced to prevent the soft glue 17 from swelling due to temperature changes and affecting the user's touch feel.
