Description

Technical Field

[0001] This utility model belongs to the field of touch panel module technology, specifically relating to a touch panel module assembly with reinforcing embedded parts. Background Technology

[0002] As a crucial input device for electronic devices such as laptops, the performance of the touchpad module is closely related to the user experience. With technological advancements and increasing user demands, touchpads not only require precise touch positioning capabilities but also need to provide high-quality tactile feedback to meet users' discerning requirements for tactile feedback.

[0003] As attached Figure 1 As shown, in order to increase the size and thickness of touchpads and improve tactile feel and performance, current market trends often include module designs with stabilizer bar components. Existing designs typically involve adding a metal reinforcing plate to the upper half of the PCBA board to enhance module strength, while the lower half requires a plastic component to accommodate the stabilizer bar's locking structure and its connection to the outer sheet metal. This results in a separate design for the plastic component and the reinforcing material on the PCBA, leading to uneven overall strength reinforcement and affecting the module's strength and stability. Therefore, this solution integrates the necessary features of the plastic component into the reinforcing sheet metal component through injection molding, achieving a unified, integrated reinforcement across the entire sheet metal surface.

[0004] Furthermore, in existing touchpad modules, the plastic components and reinforcing materials (such as sheet metal) are often designed separately, resulting in insufficient bonding between the two and uneven overall reinforcement due to material differences. This not only affects the strength and stability of the touchpad module but may also cause problems such as touch inaccuracy and abnormal noise.

[0005] Therefore, a touchpad module assembly with reinforcing embedded parts is needed to solve the problems of the existing technology, such as the use of plastic parts at the trigger end, inconsistent materials with the large surface reinforcement, and uneven overall reinforcement. Utility Model Content

[0006] The purpose of this utility model is to provide a touch panel module assembly with reinforcing embedded parts to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a touch panel module assembly with reinforcing embedded parts, comprising a supporting base plate, a glass cover plate, a PCBA board, and double-sided adhesive. The glass cover plate, PCBA board, and double-sided adhesive are sequentially disposed on the upper part of the supporting base plate. The touch panel module assembly also includes a reinforcing plate and a balance bar. A plastic part is disposed on the reinforcing plate, and the reinforcing plate is disposed between the supporting base plate and the double-sided adhesive through the plastic part and the balance bar.

[0008] It should be noted in the solution that the reinforcing plate is a sheet metal part. The entire surface is reinforced with sheet metal parts. This choice is significantly different from the traditional design of separating plastic parts and sheet metal parts. It ensures the uniform transmission of force and the balance of force, so that the overall reinforcement is uniform and the force is balanced.

[0009] It is worth noting that the reinforcing plate is made of metal materials, mainly aluminum alloy, SUS, SGCC, etc., which have high strength and good reinforcing effect.

[0010] Furthermore, it should be noted that the plastic parts are embedded in the reinforcing plate through injection molding to form an integral structure. The plastic parts are partially embedded in the sheet metal parts for noise reduction design, while maintaining a certain trigger elasticity. This also improves the bonding strength between the plastic parts and the reinforcing plate, and ensures the accuracy of the relative position, thereby improving the accuracy and stability of the entire touchpad module assembly.

[0011] In a preferred embodiment, the plastic part includes a plastic buckle and a plastic limiting member, the plastic buckle being used to grip the balance bar, and the plastic limiting member being used to control the product height and provide support.

[0012] Compared with the prior art, the touch panel module assembly with reinforcing embedded parts provided by this utility model has at least the following beneficial effects:

[0013] (1) By using a reinforcing plate made of sheet metal for reinforcement, compared with the traditional separate structure of plastic parts and sheet metal parts, the touch panel module assembly of this utility model can transmit force more evenly when subjected to force, effectively improving the overall strength and stability of the touch panel module. At the same time, due to the effective reinforcement of the reinforcing plate at the trigger end, the touch feel of triggering on both sides is more consistent, improving the user experience. The reinforcing plate design set on the sheet metal part allows the reinforcement scheme to be applied to the entire touch panel module without restriction, with consistent and balanced reinforcement effect, avoiding the problem of uneven reinforcement that may occur in traditional reinforcement methods.

[0014] (2) By embedding the plastic parts inside the reinforcing plate, it not only provides local support, but also buffers the rotation friction noise of the metal balance bar through the gripping of the plastic buckle, effectively solving the noise of metal bounce impact when pressing, making the touch panel module quieter during operation. The process of embedding the plastic parts in the reinforcing plate has higher relative position accuracy than the traditional bonding method, ensuring the accuracy and stability of the touch panel module components.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] Please see Figure 2-5 This utility model provides a touch panel module assembly with reinforcing embedded parts, including a supporting base plate 1, a glass cover plate 2, a PCBA board 3, and double-sided adhesive 4. The glass cover plate 2, PCBA board 3, and double-sided adhesive 4 are sequentially disposed on the upper part of the supporting base plate 1. Specifically, these components are stacked in sequence and fixed on the upper part of the supporting base plate 1 to form a stable and fully functional touch panel module basic structure. The touch panel module assembly also includes a reinforcing plate 5 and a balance bar 6. Plastic parts are disposed on the reinforcing plate 5, and the reinforcing plate 5 is disposed between the supporting base plate 1 and the double-sided adhesive 4 through the plastic parts and the balance bar 6.

[0023] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the reinforcing plate 5 is a sheet metal part, and the entire surface is reinforced with sheet metal. This choice is significantly different from the traditional design where plastic parts and sheet metal parts are separated. This ensures the uniform transmission of force and the balance of force, making the overall reinforcement uniform and the force balanced. The reinforcing plate 5 is made of metal materials, mainly aluminum alloy, SUS, SGCC, etc., which have high strength and good reinforcement effect. Plastic parts are also cleverly embedded in the reinforcing plate 5 through injection molding. These plastic parts not only enhance the functionality of the reinforcing plate 5, but also add noise reduction and elastic triggering characteristics to it.

[0024] During operation, the entire surface is reinforced with a sheet metal reinforcing plate 5. Compared to the traditional separate structure of plastic parts and sheet metal parts, the touchpad module assembly of this utility model can transmit force more evenly when subjected to force, effectively improving the overall strength and stability of the touchpad module. At the same time, due to the effective reinforcement of the trigger end by the reinforcing plate 5, the trigger feel on both sides is more consistent, improving the user experience. The design of the reinforcing plate 5 on the entire sheet metal part allows the reinforcement scheme to be applied to the entire touchpad module without limitation, with consistent and balanced reinforcement effect, avoiding the uneven reinforcement problem that may occur in traditional reinforcement methods.

[0025] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that the plastic parts are embedded in the reinforcing plate 5 through injection molding to form an integral structure. The plastic parts are partially embedded in the sheet metal parts for noise reduction design, while maintaining a certain trigger elasticity and improving the bonding strength between the plastic parts and the reinforcing plate 5. It also ensures the accuracy of the relative position, thereby improving the accuracy and stability of the entire touchpad module assembly. The plastic parts include plastic clips 501 and plastic limiting parts 502. Plastic clips 501 are used to hold the balance bar 6, and plastic limiting parts 502 are used to control the product height and provide support.

[0026] During operation, the design of pre-embedded plastic parts inside the reinforcing plate 5 not only provides local support, but also buffers the rotational friction noise of the metal balance bar through the gripping of the plastic clips. This effectively solves the problem of metal bounce and impact noise when pressing, making the touchpad module quieter during operation. Compared with the traditional bonding method, the process of pre-embedding plastic parts in the reinforcing plate 5 has higher relative positional accuracy, ensuring the precision and stability of the touchpad module components.

[0027] This solution has the following working process: When this device is used, firstly, according to the design requirements, a full-surface sheet metal reinforcing plate 5 is made. The sheet metal reinforcing plate 5 is made of iron material, which has high strength and good reinforcing effect. At the predetermined position of the sheet metal reinforcing plate 5, plastic parts are embedded through injection molding. During the embedding process, the plastic parts are tightly combined with the sheet metal reinforcing plate 5 to form an integrated structure. After the manufacturing is completed, the touch panel module assembly is functionally verified to ensure that the touch panel module has a uniform reinforcing effect, excellent trigger feel, and no metal impact noise or other problems.

[0028] In summary: By using a reinforcing plate 5 across the entire sheet metal surface for reinforcement, compared to the traditional separate structure of plastic and sheet metal parts, the touchpad module assembly of this invention can transmit force more evenly when subjected to stress, effectively improving the overall strength and stability of the touchpad module. Furthermore, due to the effective reinforcement of the trigger end by the reinforcing plate 5, the trigger feel on both sides is more consistent, improving the user experience. The design of the reinforcing plate 5 across the entire sheet metal surface allows the reinforcement solution to be applied without limitation to the entire touchpad module, achieving a high reinforcement effect. The design is both precise and balanced, avoiding the uneven reinforcement problems that may occur in traditional reinforcement methods. By embedding plastic parts inside the reinforcement plate 5, it not only provides local support but also buffers the rotational friction noise of the metal balance bar through the gripping of the plastic clips. This effectively solves the problem of metal bounce and impact noise when pressing, making the touchpad module quieter during operation. Compared with the traditional bonding method, the process of embedding plastic parts in the reinforcement plate 5 has higher relative positional accuracy, ensuring the precision and stability of the touchpad module components.
