Description

Technical Field

[0001] This utility model relates to the field of computer components, and in particular to a touchpad module that is easy to recognize bottom edge pressing actions. Background Technology

[0002] A touchpad is a widely used tactile input device in laptops. Users move their fingers across the touchpad to control the cursor on the screen and input information. Traditional touchpad modules consist of a panel, PCB, support plate, and base plate stacked together. The space between the support plate and base plate provides elastic feedback for touch input. However, to ensure stability in the center of the touchpad, the support plate is typically positioned around the edges. Because this support structure is relatively stable, the feedback around the edges is sluggish, making it difficult to control the pressure applied and thus hindering the recognition of presses. Therefore, improving the touchpad's sensitivity at the bottom edge requires a high degree of elastic deformation capability from the metal support plate. This necessitates optimizing the support structure to enhance the recognition of presses. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a touchpad module that can improve the tactile recognition of bottom edge pressing actions.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A touchpad module that is easy to identify bottom edge pressing actions is provided. The touchpad module is assembled from a panel, a PCB circuit board, a support mechanism, and a base plate stacked sequentially from top to bottom. The support mechanism includes a main support plate, a support base, and a support rod. The main support plate and the support base are attached and fixed to the back of the PCB circuit board. The main support plate is made of metal, and the support base is made of engineering plastic. The main support plate is located in the upper middle part of the touchpad module, and multiple horizontal limiting posts and multiple longitudinal hooks are provided along the upper edge of the main support plate. The support rod includes a rod body and connecting arms and support joints symmetrically arranged at both ends of the rod body. The connecting arms are perpendicular to the rod body, and the support joints are perpendicular to the connecting arms and parallel to the rod body. The support base is installed along the bottom edge of the touchpad module. The support base has a support rod mounting position that matches the shape of the support rod. The support rod body is rotatably mounted in the support rod mounting position. A key bracket is provided in the middle of the side of the support rod mounting position facing the main support plate on the support base. Multiple bottom plate pull heads are symmetrically arranged on both sides of the key bracket. Multiple module locking pieces are provided on the outer side of the upper edge of the bottom plate. Multiple horizontal limiting holes corresponding to the horizontal limiting posts and hanging positioning grooves corresponding to the longitudinal hook joints are provided on the inner side of the upper edge of the bottom plate. Multiple limiting springs are provided on the outer side of the lower edge of the bottom plate. The base plate has symmetrical connecting rod slots on both sides of its lower edge, each matching one-to-one with the support joint. Multiple pull grooves corresponding to the positions of the base plate pull heads are provided on the surface of the lower edge of the base plate. Each pull groove contains a hook plate matching the base plate pull head. During installation, the horizontal limiting post is inserted into the corresponding horizontal limiting hole, the longitudinal hook joint is installed into the corresponding hook positioning groove, the support joints at both ends of the support rod are inserted into the corresponding connecting rod slots, and the base plate pull head engages with the hook plate in the corresponding pull groove, leaving gaps between the base plate and the top of the main support plate and the support base.

[0005] In a preferred embodiment of this utility model, the gap between the bottom plate surface, the main support plate surface, and the top of the support seat is 0.5~1mm.

[0006] In a preferred embodiment of this utility model, the support rod mounting position includes a rod groove and rotation limiting blocks. The rod groove includes a rod body groove matching the rod body size, and arm grooves matching the connecting arm size are provided at both ends of the rod body groove. There are multiple sets of rotation limiting blocks, each set including two symmetrically arranged rotation limiting blocks on both sides of the groove opening of the rod body groove. Side stops are symmetrically installed on the outer sides of the arm grooves at both ends of the rod body groove. The base plate is provided with a block avoidance groove corresponding to the position of the rotation limiting blocks.

[0007] In a preferred embodiment of this utility model, when the support joints at both ends of the support rod are simultaneously bent inward and inserted into the connecting rod slots on both sides of the lower edge of the base plate, the connecting arm tilts toward the main support plate, and the angle between the connecting arm and the surface of the PCB board is 30~60° when tilted.

[0008] The beneficial effects of this utility model are as follows: This utility model is an improvement on the existing touch panel module structure. The original single support plate is changed into two parts: a main support plate and a support base. The support rod installed on the support base opens the bottom plate outward, while the bottom plate pull head set on the support base pulls the bottom plate inward, thereby forming an elastic support at the bottom edge. In this way, there will be obvious deformation feedback when pressing the bottom edge of the panel, which significantly improves the sensitivity of the bottom edge pressing action recognition and the user's tactile feedback. Moreover, the material performance requirements of the support base are low, and practical engineering plastics can meet the requirements, further reducing the production cost of the entire module.

[0022] Please see Figures 1 to 6 The embodiments of this utility model include:

[0023] A touchpad module with easily identifiable bottom-edge pressing action is disclosed. The touchpad module is assembled from a glass panel 1, a PCB circuit board 2, a support mechanism, and a base plate 6, stacked sequentially from top to bottom. The support mechanism includes a main support plate 3, a support base 4, and a support rod 5. The main support plate 3 and the support base 4 are attached and fixed to the back of the PCB circuit board 2. The main support plate 3 is made of iron plate, and the support base 4 is molded from polyoxymethylene. The main support plate 3 is located in the upper middle part of the touchpad module, and has two horizontal limiting posts 302 and three longitudinal hanging joints 301 along its upper edge. The support rod 5 includes a rod body 501 and connecting arms 502 and support joints 503 symmetrically arranged at both ends of the rod body. The connecting arms 502 are perpendicular to the rod body 501, and the support joints 503 are perpendicular to the connecting arms 502 and parallel to the rod body 501. The support base 4 is installed along the bottom edge of the touchpad module. The support base 4 is provided with a support rod mounting position that matches the shape of the support rod 5. The rod body 501 of the support rod 5 is rotatably mounted in the support rod mounting position. A key bracket 405 is provided in the middle of the side of the support rod mounting position facing the main support plate 3 on the support base. Four bottom plate pull heads 404 are symmetrically arranged on both sides of the key bracket 405. Three module locking pieces 604 are provided on the outer side of the upper edge of the bottom plate 6. Two horizontal limiting holes corresponding to the horizontal limiting posts 302 and two hanging positioning grooves 603 corresponding to the longitudinal hooks are provided on the inner side of the upper edge of the bottom plate 6. Three limiting spring pieces 601 are provided on the outer side of the lower edge of the bottom plate 6. The support rod 501 is symmetrically arranged on both sides of the lower edge of the bottom plate 6. The connector 503 is matched with the connecting rod slot 606. The lower edge of the base plate 6 has four pull grooves 602 that correspond one-to-one with the position of the base plate pull head 404. Each pull groove 602 has a hook plate that matches the base plate pull head 404. When the base plate 6 is installed, the horizontal limiting post 302 is inserted into the corresponding horizontal limiting hole to prevent the upper edge of the base plate 6 from moving horizontally. The longitudinal hanging connector 301 is installed into the corresponding hanging positioning groove 603 to hang the base plate 6. The support connectors 503 at both ends of the support rod 5 are inserted into the corresponding connecting rod slots 606. The base plate pull head 404 is engaged with the hook plate 605 in the corresponding pull groove 602, so that there is a gap between the base plate 6 and the plate surface of the main support plate 3 and the top of the support seat 4.In this way, the pushing force of the support rod 5 on the base plate 6 and the pulling force of the base plate pull head 404 on the base plate 6 are balanced, thus forming an elastic support. Moreover, a certain gap for deformation is maintained between the lower part of the base plate 6 and the surface of the main support plate 3. The longitudinal hook joint 301 and the hook positioning groove 603 on the main support plate 3 are fixedly connected with a relatively fixed gap. After the base plate 6 is fixed in the corresponding assembly position by the module locking piece 604, the structural characteristics of the limiting spring piece 601 can be used to not completely fix the lower edge of the base plate 6. In this way, when actually pressed, the elastic support structure deforms and absorbs the pressure while giving clear deformation feedback, which significantly improves the sensitivity of the pressing action recognition and the tactile feedback when actually pressing.

[0024] The gap between the base plate 6, the main support plate 3, and the top of the support seat is 0.5~1mm, and in actual implementation it is generally about 0.8mm. If the gap is too small, there is no elastic feedback space when pressing, and if the gap is too large, it will take up a lot of space and reduce the compactness of the laptop assembly.

[0025] The mounting position for the support rod includes a rod groove 401 and rotation limiting blocks 402. The rod groove 401 includes a rod body groove that matches the size of the rod body 501. Arm grooves matching the size of the connecting arm 502 are provided at both ends of the rod body groove. There are six sets of rotation limiting blocks 402, each set including two symmetrically arranged rotating limiting blocks 402 on both sides of the groove opening of the rod body groove. In actual installation, the rod groove 401 can increase the rotation space of the support rod 5 when pressed without changing the opening gap, improving the elastic feedback effect. The six sets of rotation limiting blocks 402 can effectively prevent the rod body 501 from dislodging from its original position or changing its angle of force during rotation without affecting the rotation of the support rod 5, thus avoiding affecting the opening gap after reset.

[0026] Side blocks 403 are symmetrically installed on the outer sides of the arm slots at both ends of the rod body groove. The base plate 6 is provided with a block avoidance groove 607 corresponding to the position of the rotation limit block 402. The purpose of setting the side blocks 403 is to prevent the connecting arms 502 on both sides of the rod body 501 from bending to both sides due to force during the pressing process, absorbing the overall elastic deformation, affecting the feel and the reset speed after release. The block avoidance groove 607 on the base plate 6 facilitates assembly. During assembly, the support joint 503 is first inserted into the corresponding connecting rod slot 606, and then the rod body 501 is snapped into the rod groove 401. The assembly difficulty is significantly reduced, the efficiency is increased, and the compactness after assembly is better.

[0027] When the support joints 503 at both ends of the support rod 5 are simultaneously bent inward and inserted into the connecting rod slots on both sides of the lower edge of the base plate 6, the connecting arm 502 tilts towards the main support plate 3. When tilted, the angle between the connecting arm 502 and the surface of the PCB board 2 is 30~60°. This tilting direction is designed so that during pressing, the base plate 6 will be subjected to inward force, causing it to tend to bend and deform inward to absorb pressure, thus not affecting the components around the mounting position. In actual design, the middle angle is generally 45°. If the angle is too small, the pressing feel will be too soft and the return will be slow; if the angle is too large, the pressing feel will be too hard and the feel will be poor.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
