Description

Technical Field

[0001] This utility model relates to the field of computer technology, and in particular to a conductive silicone-linked pressure touchpad structure. Background Technology

[0002] The touchpad module is an input device built into a laptop. As consumers' demands for products increase, in order to pursue a subjective tactile experience, high-end models will use a pressure touchpad structure. The touchpad sends a signal to the motor by touching the surface of the product with a finger, which drives the motor to vibrate. The touch vibration module and the locking base plate are connected with ordinary silicone. To prevent ESD (electrostatic discharge) failure, conductive cloth is needed to conduct current.

[0003] Since the touchpad module is a vibration module, it will vibrate when the user touches it in a preset manner. The application of conductive cloth will affect the vibration effect of the touchpad module (unsmooth vibration transmission, uneven vibration, resulting in poor vibration feel), which is not conducive to normal use by the user.

[0004] Therefore, it is necessary to propose a conductive silicone-linked pressure touchpad structure to improve the vibration effect of the touchpad module, thereby enhancing the vibration tactile feedback. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a conductive silicone-linked pressure touchpad structure to enhance the vibration effect of the touchpad module, thereby improving the tactile feedback.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a conductive silicone-linked pressure touchpad structure, including a touchpad module, a conductive silicone component, and a base plate. The bottom of the touchpad module is elastically fixedly connected to the base plate. One end of the conductive silicone component is fixedly connected to the touchpad module and forms an electrical connection, and the other end of the conductive silicone component is fixedly connected to the base plate and forms an electrical connection.

[0008] Furthermore, the conductive silicone assembly includes at least one conductive silicone sheet, one end of which is fixedly connected and electrically connected to the bottom side of the touchpad module, and the other end of which is fixedly connected and electrically connected to one side of the base plate.

[0009] Furthermore, one end of the conductive silicone sheet is provided with a first bonding conductive end, and a bonding groove is provided on one side of the bottom of the touch panel module. The first bonding conductive end is housed in the bonding groove and forms a contact electrical connection with the bottom wall of the bonding groove.

[0010] Furthermore, one end of the conductive silicone sheet is provided with a second bonding conductive end, and one side of the base plate is provided with an attachment plate. The second bonding conductive end is fixedly connected to the attachment plate, and the second bonding conductive end and the attachment plate form a contact electrical connection.

[0011] Furthermore, a clearance groove is provided on one side of the base plate, and the conductive silicone sheet passes through the clearance groove.

[0012] Furthermore, the conductive silicone sheet has a strip-shaped structure.

[0013] Furthermore, there are two conductive silicone sheets. One end of each conductive silicone sheet is fixedly and electrically connected to both sides of the bottom of the touchpad module, and the other end of each conductive silicone sheet is fixedly and electrically connected to both sides of the base plate.

[0014] Furthermore, the base plate is provided with a support connection part, and the bottom of the touch panel module is provided with multiple flexible connection bosses, all of which are fixedly connected to the support connection part.

[0015] Furthermore, the supporting connection portion includes a plurality of supporting bosses, each of which corresponds one-to-one with a plurality of flexible connecting bosses, and the flexible connecting bosses are bonded and fixedly connected to the surface of the supporting bosses.

[0016] Furthermore, the multiple support bosses are respectively distributed in the corner areas of the base plate.

[0017] The beneficial effects of this utility model are:

[0018] This invention uses a conductive silicone component to electrically connect the touchpad module to the base plate. While providing the connection function of ordinary silicone, it also conducts electricity, effectively releasing static electricity generated during operation of the touchpad module. This eliminates the need for conductive cloth for electrical connection and improves the vibration effect of the touchpad module. In summary, this conductive silicone-connected pressure touchpad structure effectively enhances the vibration effect of the touchpad module, thereby improving the tactile feedback.

[0028] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0029] Please refer to Figures 1-5 This utility model proposes a conductive silicone-linked pressure touch panel structure, including a touch panel module 1, a conductive silicone component 2, and a base plate 3. The bottom of the touch panel module 1 is elastically fixedly connected to the base plate 3. One end of the conductive silicone component 2 is fixedly connected to the touch panel module 1 and forms an electrical connection, and the other end of the conductive silicone component 2 is fixedly connected to the base plate 3 and forms an electrical connection.

[0030] In this embodiment, the touchpad module 1 has a vibration function. A vibration motor 13 is provided at the bottom of the touchpad module 1. When the touchpad module 1 is touched in a preset operation mode, the vibration motor 13 will start and vibrate for a preset time. The base plate 3 is a sheet metal structure. The touchpad module 1 and the base plate 3 are electrically connected by a conductive silicone component 2. The conductive silicone component 2 has the connection function of ordinary silicone and also has the function of conduction, so that the static electricity generated by the touchpad module 1 during operation can be effectively released through the base plate 3. This eliminates the need to use conductive cloth for electrical connection, reduces material and bonding costs, reduces costs and increases efficiency, and improves the vibration effect of the touchpad module 1.

[0031] In summary, this conductive silicone-connected pressure touchpad structure can effectively improve the vibration effect of the touchpad module, thereby enhancing the tactile feedback.

[0032] In this embodiment, the conductive silicone assembly 2 includes at least one conductive silicone sheet 21. One end of the conductive silicone sheet 21 is fixedly connected and electrically connected to one side of the bottom of the touchpad module 1, and the other end of the conductive silicone sheet 21 is fixedly connected and electrically connected to one side of the base plate 3. By bonding the conductive silicone sheet 21 to the touchpad module 1 and the base plate 3 respectively, the static electricity generated when the touchpad module 1 is operating can be released to the base plate 3. There can be one or more conductive silicone sheets 21, which can be set according to the specific static electricity release effect. The conductive silicone sheet 21 is made of methyl vinyl siloxane as the base material, silicone rubber as the substrate, and conductive fillers are added. The conductive fillers include metal springs, conductive carbon black, graphite, copper powder, silver powder, etc.

[0033] In this embodiment, one end of the conductive silicone sheet 21 is provided with a first bonding conductive end 211, and a bonding groove 11 is provided on one side of the bottom of the touch panel module 1. The first bonding conductive end 211 is housed in the bonding groove 11 and forms a contact electrical connection with the bottom wall of the bonding groove 11. The first bonding conductive end 211 is bonded to the bonding groove 11 with conductive adhesive. The bottom wall of the bonding groove 11 forms an electrical connection with the touch panel module 1. When static electricity is released, the static electricity flows through the bottom wall of the bonding groove 11 to the first bonding conductive end 211, and then flows through the conductive silicone sheet 21 to the bottom plate 3 for release.

[0034] In this embodiment, one end of the conductive silicone sheet 21 is provided with a second bonding conductive end 212, and one side of the base plate 3 is provided with an attachment plate 31. The second bonding conductive end 212 is fixedly connected to the attachment plate 31, and the second bonding conductive end 212 and the attachment plate 31 form a contact electrical connection. The second bonding conductive end 212 is bonded to the attachment plate 31 with conductive adhesive. The attachment plate 31 is integrally formed with the base plate 3. During static discharge, the static electricity eventually flows through the second bonding conductive end 212 to the attachment plate 31, and then flows through the base plate 3 for release.

[0035] In this embodiment, a clearance groove 32 is provided on one side of the base plate 3, and the conductive silicone sheet 21 passes through the clearance groove 32. In order to reduce the external space occupied by the conductive silicone sheet 21 when it is attached, the clearance groove 32 is provided as the through space of the conductive silicone sheet 21, so that the conductive silicone sheet 21 can be located below the touch panel module 1.

[0036] In this embodiment, the conductive silicone sheet 21 has a strip-shaped structure, which facilitates quick attachment and fixation.

[0037] In this embodiment, there are two conductive silicone sheets 21. One end of each conductive silicone sheet 21 is fixedly and electrically connected to both sides of the bottom of the touchpad module 1, and the other end of each conductive silicone sheet 21 is fixedly and electrically connected to both sides of the base plate 3. In order to make the vibration of the touchpad module 1 more even and improve the vibration effect, the optimal number and position of the two conductive silicone sheets 21 are each set on both sides of the bottom of the touchpad module 1. This can effectively release static electricity and improve the vibration effect of the touchpad module 1.

[0038] In this embodiment, the base plate 3 is provided with a support connection part 33, and the bottom of the touch panel module 1 is provided with a plurality of flexible connection protrusions 12, all of which are fixedly connected to the support connection part 33. When the touch panel module 1 is installed, the support connection part 33 can support the touch panel module 1, and the touch panel module 1 can be pressed by its own elasticity. The plurality of flexible connection protrusions 12 also provide the pressing elasticity, making the pressing feel of the touch panel module 1 better.

[0039] In this embodiment, the support connection part 33 includes a plurality of support bosses 331, each of which corresponds to a plurality of flexible connection bosses 12. The flexible connection bosses 12 are bonded and fixedly connected to the surface of the support bosses 331. The flexible connection bosses 12 can be made of silicone material. The arrangement of multiple support bosses 331 can provide more downward pressure space between the base plate 3 and the touchpad module 1, improving the pressing feel of the touchpad module 1. At the same time, when the touchpad module 1 vibrates by the vibration motor 13, the large space below makes the vibration feel even better.

[0040] In this embodiment, multiple support bosses 331 are distributed in the corner areas of the base plate 3, which helps to increase the space under the touchpad module 1 and effectively improve the pressing feel and vibration feel.

[0041] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
