[0002] A full-area touchpad refers to a touchpad that can be operated on the entire touchpad surface. Compared with a traditional touchpad, a full-area touchpad has a wider touch area and a more flexible operation method. When a full-area touchpad is used, it is usually installed on a corresponding bracket.

[0003] For example, a Chinese patent with announcement number: CN212846558U, title: A notebook touchpad support frame, announcement date: 2021-03-30, includes a support plate, the front edge of the support plate extends forward to form a plurality of latches, a heat dissipation hole is provided in the middle of the support plate, an adhesive layer is coated on the upper surface of the support plate, a release paper layer is attached to the adhesive layer, the release paper layer has a handle for lifting it, a plurality of connecting ears are connected to the rear edge of the support plate, at least two connecting holes are provided on the connecting ears, a fixing spring is fixed on the back of the support plate, a strip hole is provided on the part of the fixing spring protruding from the support plate, a supporting spring is connected to the support plate, the supporting spring is arranged in the heat dissipation hole, and the supporting spring protrudes from the upper surface of the support plate. Effectively improve the efficiency of touchpad assembly, and the overall buffering effect is good;

[0004] The above-mentioned prior art has the following technical problems: when the existing touchpad bracket is in use, it is connected to the laptop cover through the connecting holes thereon. However, during actual assembly, since the position of the connecting holes on the touchpad is fixed, the connecting holes on the bracket and the laptop cover are misaligned, which easily affects the normal bolt fixing. At the same time, in order to ensure that the touchpad has a good heat dissipation effect, the existing bracket has corresponding heat dissipation holes. Although the heat dissipation holes can improve the heat dissipation effect of the touchpad, when working in a low temperature environment, the heat dissipation holes cannot be closed, so that the opening of the heat dissipation holes increases the working impact of the touchpad in a low temperature state, which may cause the physical and chemical properties of the touchpad to change at low temperatures, making the touch less sensitive, thereby weakening the user's touch response.

[0005] Therefore, we propose a full-area touchpad bracket to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a full-range touchpad bracket to solve the problem raised in the above background technology that the existing touchpad brackets on the market are connected to the laptop cover through the connecting holes thereon when in use.

At the same time, in order to ensure that the touchpad has a good heat dissipation effect, the existing bracket opens corresponding heat dissipation holes. Although the heat dissipation holes can improve the heat dissipation effect of the touchpad, when working in a low temperature environment, the heat dissipation holes cannot be closed, thereby increasing the working influence of the touchpad in a low temperature state due to the opening of the heat dissipation holes, which may cause the physical and chemical properties of the touchpad to change at low temperatures, making the touch less sensitive, thereby weakening the user's touch response.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: when the global touchpad bracket is connected to the notebook computer cover, the installation position of the bolt can be conveniently moved and adjusted according to actual needs, thereby improving the convenience of connecting the bracket to the notebook computer cover.

[0032] 3. Memory metal is provided. When the global touch panel works for a long time at a high temperature, the memory metal deforms after absorbing heat. The deformation of the memory metal can pull the side movable plate to move relatively.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1: Please refer to Figure 1-Figure 9 When the existing touchpad bracket is in use, it is connected to the notebook computer cover through the connecting hole on it. However, during actual assembly, since the position of the connecting hole on the touchpad is fixed, the connecting hole on the bracket and the notebook computer cover are misaligned, which easily affects the normal bolt fixing. In order to solve this technical problem, this embodiment discloses the following technical contents;

[0046] A full-range touchpad bracket comprises a bracket body 1, a mounting window 2 is provided in the middle of the bracket body 1, the mounting window 2 is used to avoid the circuit board of the full-range touchpad, and a docking side ear 3 is fixedly connected to the side of the bracket body 1, and a locking groove 4 for a bolt to pass through is provided on the docking side ear 3; a connecting groove 5 is provided on the upper surface of the bracket body 1, and an elastic buffer component 6 is installed on the inner side of the connecting groove 5, and the elastic buffer component 6 is used to buffer the pressing force received by the full-range touchpad, reduce the rigid impact between the full-range touchpad and the bracket body 1 ... The components 6 are evenly distributed on the bracket body 1; the elastic buffer component 6 includes a silicone pad 601, a bearing seat 602, an inner recess 603, a metal spring 604 and a guide air hole 605; the lower end of the silicone pad 601 is fixed on the bearing seat 602, and the middle of the upper surface of the bearing seat 602 is recessed toward the center of the bearing seat 602 to form the inner recess 603, the edge of the inner recess 603 is fixedly connected with a metal spring 604 extending toward the center of the inner recess 603, and the side of the silicone pad 601 is provided with a guide air hole 605 for air intake and exhaust. The interior of the silicone pad 601 is set as a hollow structure, and the internal airflow of the silicone pad 601 is connected to the external airflow through the guide air hole 605, and the silicone pad 601 is located directly above the metal spring 604. The height of the inner recess 603 on the support seat 602 is greater than the thickness of the metal spring pieces 604 , and the metal spring pieces 604 are evenly distributed at equal angles along the inner recess 603 with a circular cross-section, and the support seat 602 can rotate in the connection slot 5 .

[0047] When the full-area touchpad bracket is needed, the full-area touchpad is installed on the bracket body 1, and then the bolt is passed through the locking groove 4 on the side ear 3 on the side of the bracket body 1, and then screwed into the notebook cover to complete the fixation of the bracket body 1 and the notebook cover. The locking groove 4 is set to a waist-shaped structure, which can facilitate the movement and adjustment of the bolt in the locking groove 4, and then fine-tune according to the position of the screw hole on the notebook cover, thereby improving the convenience of connecting the bracket body 1 with the notebook cover. Thereafter, when the user frequently presses the full-area touchpad when using a laptop computer, the full-area touchpad can transfer the pressure to the silicone pad 601 and the metal spring 604 on the supporting seat 602 below after being pressed. Through the elastic deformation of the silicone pad 601 and the metal spring 604, the pressing force can be effectively buffered, so that the full-area touchpad can rebound after being pressed.

[0048] Embodiment 2: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1. In order to ensure that the touch panel has a good heat dissipation effect, the existing bracket is provided with corresponding heat dissipation holes 7. Although the heat dissipation holes 7 can improve the heat dissipation effect of the touch panel, when working in a low temperature environment, the heat dissipation holes 7 cannot be closed. As a result, the opening of the heat dissipation holes 7 increases the influence of the touch panel working in a low temperature state, which may cause the physical and chemical properties of the touch panel to change at low temperatures, making the touch less sensitive, thereby weakening the user's touch response. In order to further solve this technical problem, this embodiment discloses the following technical content, such as Figure 1-Figure 9 As shown;

[0049] The connecting groove 5 is provided with a heat dissipation hole 7 for ventilation and heat dissipation, and a temperature control and adjustment component 8 is installed inside the connecting groove 5, and the temperature control and adjustment component 8 is used to open the heat dissipation hole 7 when the temperature is high, and to cover the heat dissipation hole 7 when the temperature is low. The docking side ears 3 are evenly distributed on the side of the bracket body 1. A locking groove 4 is provided on each docking side ear 3, and the locking grooves 4 on the docking side ears 3 are all set as waist-shaped holes. The temperature control and adjustment component 8 includes a memory metal 801, a movable plate 802, a guide hole 803, a blocking block 804, a connecting frame 805, a first branch rod 806, a second branch rod 807, a clamping frame 808 and a steering block 809; the memory metal 801 is installed on the inner side of the connecting groove 5, and the end of the memory metal 801 is connected to the movable plate 802, the movable plate 802 is provided with a guide hole 803, and the movable plate 802 is fixedly connected to the blocking block 804, the side of the blocking block 804 is fixedly connected to the connecting frame 805, and the first branch rod 806 and the second branch rod 807 are fixedly connected to the connecting frame 805, the end of the connecting frame 805 away from the blocking block 804 is inserted through the clamping frame 808, and the clamping frame 808 is fixedly connected to the steering block 809, and the clamping frame 808 is fixedly connected to the upper end edge of the supporting seat 602. The movable plate 802 can slide on the connection slot 5, and the guide hole 803 on the movable plate 802 is misaligned with the heat dissipation hole 7 on the connection slot 5 in the initial state, and the diameter of the guide hole 803 is the same as the diameter of the heat dissipation hole 7. The blocking block 804 is set as an arc structure, and the connection frame 805 fixed on the blocking block 804 is set as an L-shaped structure, and the blocking block 804 and the movable plate 802 are vertically distributed. The first branch rod 806 and the second branch rod 807 on the connection frame 805 are distributed on both sides of the steering block 809 on the clamping frame 808.

[0050] When the global touch panel is working at a normal temperature, the memory metal 801 does not deform. At the same time, in the initial state, the blocking block 804 on the movable plate 802 blocks the guide air holes 605 on the side of the silicone pad 601. At this time, when the user presses the global touch panel, the guide air holes 605 on the silicone pad 601 will not blow air toward the regional touch panel, so the air flow rate around the global touch panel will not increase, so that the global touch panel can work at a normal temperature. When the temperature of the working area of ​​the global touch panel is high, the memory metal 801 is deformed by heat. After the deformation, the memory metal 801 can pull the two movable plates 802 on the side to move relatively. After the movable plate 802 moves, the guide hole 803 on it coincides with the heat dissipation hole 7 in the connecting groove 5, so that the heat dissipation hole 7 can be used to heat the touch panel. Normal ventilation and cooling can be carried out. At the same time, after the movable plate 802 moves, the connecting frame 805 on the side of the blocking block 804 can drive the first branch rod 806 and the second branch rod 807 to move synchronously, and after the second branch rod 807 moves, it can push the steering block 809 on the clamping frame 808. At this time, the steering block 809 can drive the clamping frame 808 and the supporting seat 602 fixed at the lower end of the clamping frame 808 to rotate. After the supporting seat 602 rotates, the guide air hole 605 on the side of the silicone pad 601 is directed toward the full-area touchpad. Thereafter, when the user frequently presses the full-area touchpad, the silicone pad 601 can be compressed to blow the internal airflow toward the full-area touchpad through the guide air hole 605, so as to speed up the air flow rate around the full-area touchpad and improve the cooling efficiency of the full-area touchpad.
