Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, specifically a front door outer panel window sill reinforcement plate. Background Technology

[0002] The front door outer panel window sill reinforcement plate is a key component in the automotive door structure. It is made of high-strength alloy steel and features a complex curved surface and bending design, designed to improve the strength and rigidity of the door window sill area. Through robust connection methods such as welding or riveting, the reinforcement plate is tightly connected to components such as the outer and inner door panels, effectively enhancing the door's rigidity, sealing, and safety. With the continuous development of the automotive industry, the design of the front door outer panel window sill reinforcement plate is also constantly innovating to meet higher performance requirements.

[0003] Currently, the window reinforcement plates installed on the outer door panels are mostly welded to the outer door panels in most car manufacturing plants using automated welding. The reinforcement plates need to be overlapped on the inside of the outer door panel, then clamped and fixed with jigs before the automatic welding operation. During this process, operators need to handle and move the reinforcement plates. Since the reinforcement plates are made of punched sheet metal and are relatively thin, they can easily cause scratches to the operators' hands, reducing the safety and convenience of the reinforcement plate installation. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a front door outer panel window sill reinforcement plate to solve the technical problem of low protection for operators provided by the reinforcement plate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a front door outer panel window sill reinforcement plate, including a reinforcement plate body, the reinforcement plate body including a protrusion, the protrusion being provided with two sets of gripping mechanisms, the gripping mechanism including a gripping groove, the inner side of the gripping groove being provided with an inward flange at both the upper and lower sides, the inward flange protecting the operator's hand.

[0006] By adopting the above technical solution, the gripping mechanism on the protrusion greatly facilitates the installation and maintenance work of the operator. The gripping groove allows the operator to easily grip the reinforcing plate, improving the convenience of operation.

[0007] Furthermore, the inner flange has an arc-shaped structure and is a stamped bending structure.

[0008] By adopting the above technical solution, not only is the reinforcing plate more visually appealing, but the arc-shaped structure can also better distribute the pressure on the hand and improve the comfort of holding it.

[0009] Furthermore, a reinforcing ridge is connected above the protrusion, and both the protrusion and the reinforcing ridge have a "C" shaped cross-section.

[0010] By adopting the above technical solution, the reinforcing strip enhances the strength of the reinforcing plate in a specific area, enabling the entire reinforcing plate to withstand pressure more stably when facing external impacts, and improving its resistance to deformation.

[0011] Furthermore, an upper flange is connected above the reinforcing ridge, and a lower flange is connected below the ridge.

[0012] By adopting the above technical solution, not only is the contact area between the reinforcing plate and the outer door panel increased, but the tight fit also improves the firmness of the connection, effectively preventing loosening or detachment due to vibration or external force during use.

[0013] Furthermore, the surface of the protrusion is provided with multiple through holes, which are arranged linearly at equal intervals, and the inner side of the through holes is formed with a concave flange.

[0014] By adopting the above technical solution, the through holes not only reduce the weight of the reinforcing plate, but also enable the reinforcing plate to distribute pressure more evenly when under stress, thereby improving its impact resistance.

[0015] Furthermore, the two sides of the main body of the reinforcing plate are respectively fixedly connected to a first overlapping part and a second overlapping part, which are the welding points between the reinforcing plate and the outer panel of the car door.

[0016] By adopting the above technical solution, the first and second overlapping parts provide stable welding points for the connection between the reinforcing plate and the outer panel of the door, ensuring that the reinforcing plate can be firmly fixed to the door, improving the reliability and stability of the connection. At the same time, it also makes the installation process of the reinforcing plate simpler and more convenient, reducing the complexity and difficulty of the installation process, and further improving the installation efficiency and accuracy.

[0017] Furthermore, the upper flange is provided with multiple mounting grooves for securing the waterproof adhesive strip.

[0018] By adopting the above technical solution, multiple mounting slots provide a convenient interface for the installation of waterproof strips, allowing the waterproof strips to be firmly snapped into the mounting slots, effectively preventing rainwater or moisture from seeping into the interior of the car door, and improving the sealing and waterproof performance of the car door.

[0019] In summary, the present invention has the following main advantages: 1. This utility model features a gripping mechanism. During installation or maintenance, operators may need to hold the reinforcing plate. The gripping groove allows operators to pass their hands through the groove. The inner arc-shaped inward folding edge of the groove prevents the sharp edges from directly contacting the hands, thereby improving the protection of the operator's hands and making the operation process safer and more convenient. 2. This utility model utilizes a gripping groove and an inner flange. The inner flange, folded inside the gripping groove, effectively enhances the structural strength of the gripping groove. As a reinforcing edge, the inner flange not only strengthens the load-bearing capacity of the gripping groove but also prevents edge deformation or tearing caused by external forces, ensuring the stability and reliability of the gripping groove during use. At the same time, the gripping groove also reduces the weight of the reinforcing plate by removing some unnecessary materials, thus reducing the overall weight of the reinforcing plate. This makes the reinforcing plate lighter and easier to operate while maintaining sufficient strength and rigidity, improving the convenience of installation and maintenance.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1: A type of front door outer panel window sill reinforcement plate, such as Figure 1-4As shown, the device includes a reinforcing plate body 1, which includes a protrusion 101. Two sets of gripping mechanisms 4 are provided on the protrusion 101. Each gripping mechanism 4 includes a gripping groove 401, with inwardly turned edges 402 on both the upper and lower inner sides of the gripping groove 401. The inwardly turned edges 402 protect the operator's hands. The gripping mechanisms 4 on the protrusion 101 greatly facilitate the installation and maintenance work of the operator. The gripping groove 401 allows the operator to easily grip the reinforcing plate, improving the ease of operation. Simultaneously, the inwardly turned edges 402 on the upper and lower inner sides of the gripping groove 401 effectively prevent direct contact between sharp edges and the operator's hands, reducing safety hazards during operation and providing good protection for the operator's hands, making the entire reinforcing plate safer and more reliable to use.

[0024] See Figure 3 , Figure 4 The inner flange 402 has an arc-shaped structure, which is a stamped and bent structure. This not only makes the reinforcing plate more visually appealing, but the arc-shaped structure can also better distribute the pressure on the hand and improve the grip comfort. At the same time, as a stamped and bent structure, the inner flange 402 has a simple manufacturing process and low cost, and can ensure sufficient strength and rigidity, effectively preventing deformation or damage due to external forces during use, and further improving the durability and reliability of the reinforcing plate.

[0025] Example 2: See Figure 1 , Figure 2 A reinforcing rib 106 is connected above the protrusion 101. Both the protrusion 101 and the reinforcing rib 106 have a "C" shaped cross-section. The reinforcing rib 106 enhances the strength of the reinforcing plate in a specific area, enabling the entire reinforcing plate to withstand pressure more stably when facing external impacts, thus improving its resistance to deformation. At the same time, the "C" shaped protrusion 101 and the reinforcing rib 106 not only increase the rigidity of the reinforcing plate, but also improve the stability and reliability of the connection, further enhancing the overall performance and safety of the door.

[0026] See Figure 1 , Figure 2 The upper part of the reinforcing ridge 106 is connected to the upper flange 102, and the lower part of the ridge 101 is connected to the lower flange 103. This not only increases the contact area between the reinforcing plate and the outer door panel, but also improves the firmness of the connection through tight fitting, effectively preventing loosening or falling off due to vibration or external force during use. At the same time, the lower flange 103 below the ridge 101 also plays a similar role. It enhances the support of the reinforcing plate under the door, making the entire reinforcing plate more stably fixed to the door, and further improving the overall rigidity and strength of the door.

[0027] See Figure 1 , Figure 2 The surface of the protrusion 101 is provided with a plurality of through holes 104, which are arranged linearly at equal intervals. The inner side of the through holes 104 is formed with a concave flange 105. The through holes 104 not only reduce the weight of the reinforcing plate, but also enable the reinforcing plate to distribute pressure more evenly when subjected to force, thereby improving its impact resistance. At the same time, the concave flange 105 on the inner side of the through holes 104 increases the strength of the edge of the through holes, preventing edge tearing or deformation caused by external force, and further improving the durability and reliability of the reinforcing plate.

[0028] See Figure 1 , Figure 2 The main body 1 of the reinforcing plate is fixedly connected to the first overlapping part 2 and the second overlapping part 3 on both sides, which are the welding points between the reinforcing plate and the outer panel of the door. The first overlapping part 2 and the second overlapping part 3 provide stable welding points for the connection between the reinforcing plate and the outer panel of the door, ensuring that the reinforcing plate can be firmly fixed to the door, improving the reliability and stability of the connection. At the same time, it also makes the installation process of the reinforcing plate simpler and more convenient, reducing the complexity and difficulty of the installation process, and further improving the installation efficiency and accuracy. In addition, the use of welding connection method also enhances the bonding strength between the reinforcing plate and the door, making the entire door more robust and durable.

[0029] See Figure 1 , Figure 2 The upper flange 102 has multiple mounting slots 107 for securing the waterproof strip. The multiple mounting slots 107 provide a convenient interface for the installation of the waterproof strip, allowing the waterproof strip to be securely secured in the mounting slots. This effectively prevents rainwater or moisture from seeping into the interior of the door, improving the door's sealing and waterproof performance. At the same time, it also makes the replacement and maintenance of the waterproof strip simpler and more convenient, reducing the complexity and difficulty of the maintenance process.

[0030] The implementation principle of this embodiment is as follows: The main body 1 of the reinforcing plate is provided with a protrusion 101 to enhance local strength, and at the same time, it is provided with an upper flange 102 and other structures for firmly connecting with the outer panel of the car door. The reinforcing plate is made of high-strength alloy steel, which has excellent impact resistance and deformation resistance. The first overlapping part 2 and the second overlapping part 3 are welded to the outer door to tightly connect the main body 1 of the reinforcing plate to the car door component, which effectively improves the strength and rigidity of the car door window sill area, thereby improving the overall performance of the car door. When the operator needs to hold the reinforcing plate, the operator can first pass his / her hand through the grip groove 401. At this time, the arc-shaped inner flange 402 folded up and down on the inner side of the grip groove 401 helps to avoid the relatively sharp edge directly contacting the operator's hand, which helps to improve the protection of the operator's hand.
