[0033] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0034] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.
[0035] Please see Figures 1 to 3 This utility model provides a touchpad module, including a touch panel 1, a touch circuit board 2, a support plate 3, and a base plate 4. This simplifies the main components of the touchpad module, which helps reduce production costs. Furthermore, the touch panel 1, touch circuit board 2, support plate 3, and base plate 4 are connected sequentially along a first direction. It should be noted that the first direction is perpendicular to the pressing plane of the touch panel 1.
[0036] The support plate 3 has a connecting part 31, through which the support plate 3 and the base plate 4 are connected with a gap. A spring-loaded element 5 is located on the side of the support plate 3 away from the connecting part 31, between the support plate 3 and the base plate 4, serving to support the support plate 3. When the user presses the touch panel 1, the spring-loaded element 5 acts as a buffer; after the user stops pressing the touch panel 1, the touch panel 1 returns to its initial position under the rebound force of the spring-loaded element 5, improving the user experience. Furthermore, by selecting a spring-loaded element 5 with appropriate rebound force, the pressing pressure and rebound function of the touch panel 1 can be precisely adjusted.
[0037] The support plate 3 is provided with a first reinforcing structure 32, and the base plate 4 is provided with a second reinforcing structure 41, thereby improving the structural strength of the support plate 3 and the base plate 4. This helps to prevent deformation of the support plate 3 and the base plate 4 during processing and assembly, providing stable support for the touch panel 1 and the touch circuit board 2, and reducing the scrap rate of the touch panel module. At the same time, it also helps to ensure the aesthetics of the touch panel module.
[0038] For example, the spring element 5 is connected to the support plate 3. The spring element 5 may include, but is not limited to, elastic foam. Using elastic foam allows it to be attached to the support plate 3 by adhesive, which helps reduce production costs.
[0039] In one example, the first reinforcing structure 32 is a series of crisscrossing ribs on the support plate 3, which improve the structural strength of the support plate 3. The middle part of the base plate 4 is set as a hollow structure, and two perpendicularly intersecting ribs are set inside the hollow structure to form a second reinforcing structure 41, which improves the structural strength of the base plate 4.
[0040] In some embodiments, the connecting part 31 is provided with a first mounting hole 33, and the base plate 4 is provided with a second mounting hole 42 that cooperates with the first mounting hole 33. The first mounting hole 33 and the second mounting plate can be connected by screws or the like, thereby connecting the support plate 3 to the base plate 4.
[0041] In one example, the connecting part 31 includes a connecting adapter 311 and a mounting part 312 connected together. The adapter 311 extends toward the base plate 4 so that the mounting part 312 can be parallel to and offset from the support plate 3. A first mounting hole 33 is provided on the mounting part 312 so that there is a gap between the support plate 3 and the base plate 4 after they are connected.
[0042] For example, to reduce the connection structure between the support plate 3 and the connecting part 31, the support plate 3 and the connecting part 31 are integrally injection molded. Furthermore, the adapter 311 is disposed on the side wall of the support plate 3 and is set at an acute angle to the side wall of the support plate 3, avoiding a right angle between them, which would cause stress concentration at the connection point and improve the structural strength of the connection. Moreover, by adjusting the angle between the adapter 311 and the support plate 3, the connection strength and elasticity between them can be adjusted.
[0043] In some embodiments, during the installation of the support plate 3 onto the base plate 4, to facilitate quick alignment of the first mounting hole 33 and the second mounting hole 42, the relative position of the support plate 3 on the base plate 4 can be limited first. To achieve this, the support plate 3 is provided with a socket 34, and the base plate 4 is provided with a tongue 43 that mates with the socket 34. By inserting the tongue 43 into the socket 34, the position of the support plate 3 on the base plate 4 is limited.
[0044] For example, the support plate 3 and the socket 34 are integrally injection molded.
[0045] In one example, when a user presses the touch panel 1, the socket 34 can move relative to the latch 43 along a first direction. To prevent noise from occurring between the socket 34 and the latch 43 during movement, damping pads are provided on opposite sides of the socket 34 and the latch 43 along the first direction. During movement, the socket 34 contacts the latch 43 through the damping pads, thus preventing collisions and avoiding noise.
[0046] For example, a shock-absorbing pad is connected to the socket 34, including but not limited to a rubber pad. Using a rubber pad allows it to be attached to the socket 34 via adhesive, which helps reduce production costs.
[0047] In some embodiments, in order to further limit the relative position between the support plate 3 and the base plate 4, a limiting pin 313 is provided on the connecting part 31 and a limiting hole 44 is provided on the base plate 4. The limiting pin 313 and the limiting hole 44 cooperate to limit the position of the support plate 3.
[0048] For example, the limiting pin 313 is disposed on the mounting component 312 of the connecting portion 31, located near the first mounting hole 33. The limiting hole 44 can be configured as a strip-shaped hole, the length direction of which is consistent with the direction in which the tongue 43 moves within the socket 34 along a second direction. It should be noted that the second direction is perpendicular to the first direction.
[0049] In some embodiments, an elastic support member 21 is provided on the touch circuit board 2. A notch 35 is provided on the support plate 3, and the elastic support member 21 is located at the notch 35. Due to the gap between the support plate 3 and the base plate 4, by abutting the elastic support member 21 against the base plate 4, the base plate 4 supports the touch circuit board 2 through the elastic support member 21. At the same time, because the elastic support member 21 is elastic, it will not affect the user's pressing of the touch panel 1.
[0050] For example, the elastic support 21 may include, but is not limited to, a plastic part, which can be attached to the touch circuit board 2 with polyester tape, which helps to reduce production costs.
[0051] In one example, both the socket 34 and the notch 35 are located on the side of the support plate 3 away from the connecting part 31, so that the support plate 3 and the base plate 4 are limited by the cooperation of the socket 34 and the tongue 43, and the elastic support 21 plays the role of supporting the touch circuit board 2.
[0052] In some embodiments, to avoid the risk of electric shock when the user uses the touchpad module, the touch circuit board 2 is provided with a conductive element 22, and the support plate 3 is provided with a clearance port 36. A grounding element 6 is connected to the clearance port 36, and the grounding element 6 is connected to the conductive element 22 through the clearance port 36, thereby helping to ensure the safety of the user.
[0053] In one example, the support plate 3 is provided with a positioning boss 37, and the grounding component 6 is provided with a positioning hole that cooperates with the positioning boss 37. Through the cooperation between the two, it is easy to position the grounding component 6 on the support plate 3.
[0054] For example, the conductive component 22 may include, but is not limited to, conductive foam. Using conductive foam allows it to be attached to the touch circuit board 2 via adhesive bonding, which helps reduce production costs.
[0055] One embodiment of the present invention provides a laptop computer that includes the touchpad module described above.
[0056] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
