[0034] The present application provides a touchpad.

[0035] In the embodiments of the present application, the touchpad comprises:

[0036] A connecting shaft 500;

[0037] Two fixing members 200, two fixing members 200 are fixedly connected to two ends of the connecting shaft 500 respectively, a plurality of limiting grooves 220 are arranged on the fixing member 200 in a circumferential direction, and the limiting grooves 220 of the two fixing members 200 are oppositely opened.

[0038] Two supporting plates 300, the supporting plate 300 is provided with a sleeving part 310, the sleeving part 310 is sleeved on the connecting shaft 500, the sleeving parts 310 of the two supporting plates 300 are distributed in the axial direction of the connecting shaft 500, and the limiting convex parts 320 are arranged on the opposite sides of the sleeving parts 310 in the axial direction, the supporting plate 300 can move axially relative to the connecting shaft 500 to have a first position and a second position, in the first position, the limiting convex part 320 is selectively clamped into the limiting groove 220 to limit the circumferential rotation of the supporting plate 300 relative to the connecting shaft 500, in the second position, the limiting convex part 320 is separated from the limiting groove 220, and the supporting plate 300 can rotate circumferentially relative to the connecting shaft 500.

[0039] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the connecting shaft 500 is connected with two oppositely arranged fixing members 200, the connection mode is fixed connection, and the two fixing members 200 are respectively located at two ends of the connecting shaft 500, so that the connecting shaft 500 has a space for connecting the supporting plate 300, and the space is located between the two oppositely arranged fixing members 200. Two supporting plates 300 are installed in the space of the connecting shaft 500 for installing the supporting plate 300, and the connecting mode of the supporting plate 300 and the connecting shaft 500 is movable connection, which enables the supporting plate 300 to rotate around the axis of the connecting shaft 500 and move along the axial direction of the connecting shaft 500. In this embodiment, the movable connection is realized by arranging the sleeving part 310 connected with the connecting shaft 500 on the supporting plate 300, and the distribution direction of the sleeving parts 310 of the two supporting plates 300 is consistent with the axial direction of the connecting shaft 500. A plurality of limiting grooves 220 (circumferential direction) are arranged on the fixing member 200 in the technical scheme of the application, the groove openings of the limiting grooves 220 are axial, and the position direction is in the direction of the axial direction of the connecting shaft 500. The supporting member is provided with a limiting convex part 320, the limiting grooves 220 of the two fixing members 200 on the connecting shaft 500 are oppositely arranged, the limiting convex parts 320 on the two supporting plates 300 on the connecting shaft 500 are oppositely arranged, and the limiting grooves 220 can limit the position of the limiting convex part 320 in the axial direction of the connecting shaft 500. Because the limiting grooves 220 are arranged in the circumferential direction of the connecting shaft 500, the fixing member 200 can limit the circumferential rotation of the supporting plate 300 on the connecting shaft 500.

[0040] In the technical solution, when the support plate 300 is in the first position, the limiting recess 220 is clamped by the limiting protrusion 320, and the movement of the limiting protrusion 320 is limited; when the support plate 300 is in the second position, the limiting protrusion 320 is out of the limitation of the limiting recess 220. It can be understood that the limiting protrusion 320 can switch between the first position and the second position through the movement of the support member in the axial direction of the connecting shaft 500, and when the limiting protrusion 320 is out of the limitation of the limiting recess 220 and is in the second position, the support member can rotate around the connecting shaft 500, so that the relative positions of the two support members change constantly with the rotation of each support member, until the limiting protrusion 320 of the support member is clamped in a limiting recess 220 in the fixing member 200 again, and the relative position is fixed. Since there are multiple limiting recesses 220 in the fixing member 200, the relative positions of the two support members on the connecting shaft 500 also have multiple positions. In the second state of the touchpad as a mouse, the angle between the two support plates 300 can be adjusted according to the user's hand shape, so that the touchpad in the second state can be fitted to the user's hand, thereby facilitating the user's operation. In the first state or the second state of the touchpad, the support plate 300 can sense the user's touch operation, so that the user can perform corresponding operations on the notebook computer through the touchpad.

[0041] It can be understood that the adjustment process of the shape of the touchpad is as follows: first, the shape of the touchpad is adjusted before the support plate 300 is in the first position. The user needs to pull out the limiting protrusion 320 of the support plate 300 from the corresponding limiting recess 220. This step realizes the conversion of the support plate 300 from the first position to the second position, and also makes the support plate 300 out of the limitation of the fixing member 200, so that it can rotate around the connecting shaft 500. When the support plate 300 is in the second position, the user adjusts the support plate 300 to the appropriate position, and then inserts the limiting protrusion 320 in the support plate 300 into the limiting recess 220 in the fixing member 200, realizing the conversion of the support plate 300 from the second position to the first position, and adjusting the shape of the touchpad.

[0042] Therefore, in the technical solution of the present application, in the first state of the touchpad, the touchpad is installed on the device main body 800, and the two support plates 300 are relatively flat, i.e., used as a traditional touchpad for simple click operation by the user. If the user needs to perform more complex operations, the touchpad can be removed from the device main body 800, and the shape of the touchpad can be adjusted to adapt the angle between the two support plates 300 to the user's hand, so that the touchpad is switched to the second state, i.e., can be used as a mouse for the user to operate.

[0043] Further, the same side of the two support plates 300 is provided with a touch panel 100, and the touch panel 100 is provided with at least one pressure sensor. In the first state, the pressure sensor is electrically connected to the main control board of the device main body 800, and in the second state, the pressure sensor is communicatively connected to the main control board. It can be understood that the same side of the two support plates 300 is provided with a touch panel 100, that is, all the touch panels 100 are located on one side of the touch panel. In this embodiment, at least one pressure sensor is arranged on the touch panel 100 to enable one side of the touch panel to have the function of identifying external information. Of course, in other embodiments, a capacitive sensor can be arranged to identify external information. That is, the support between the electrodes of the capacitive sensor is a structure that deforms with pressure changes, and the deformation of the structure in turn causes the capacitance to change, so that information can be identified according to the change in capacitance.

[0044] The technical solution divides the state of the touch panel into a first state and a second state. The first state is when the touch panel is installed on a notebook computer, and the second state is when the touch panel is separated from the notebook computer. When the touch panel is in the first state, the pressure sensor is electrically connected to the main control board of the device main body 800, that is, the pressure sensor and the device main body 800 are connected through a conductive connection to transmit information. This connection method simplifies the connection steps and procedures, and improves the assembly efficiency to a certain extent. The technical solution also provides that when the touch panel is in the second state, the pressure sensor is communicatively connected to the main control board, that is, information is transmitted through wireless connection. This connection method enables the device main body 800 and the touch panel to be separated, and the touch panel is not limited by the position of the device main body 800, which better improves the user's experience. It can be understood that the operation logic of the touch panel in the second state is different from that in the first state, and is similar to the operation logic of the mouse, that is, the two touch panels in the touch panel do not all operate, one of which supports the other. Although the touch panel that supports the information will also identify information, the main control board will not have information feedback, and the touch panel that operates has two sensing areas distributed in the left and right directions, and the main control board processes and feedbacks information of the sensing areas on the left and right sides differently. The left sensing area is consistent with the left button information processing and feedback of the mouse, and the right sensing area is consistent with the right button information processing and feedback of the mouse. Further, for the convenience of user operation, a separation line can be arranged on the touch panel that operates to distinguish the sensing areas on the left and right sides.

[0045] Further, each of the support plates 300 is formed with a mounting cavity, a battery is accommodated in the mounting cavity, the pressure sensor is fixedly connected to the touch panel 100 and electrically connected to the battery in the corresponding mounting cavity, and the battery is electrically connected to the main control plate in the first state. Understandably, the establishment of the battery in the mounting cavity can enable the touch panel to have a power supply to maintain the functions of communication and information receiving when in the second state. In the first state, the battery is electrically connected to the main control plate, that is, the battery is charged for use in the second state, which meets the endurance requirement of the battery and improves the use efficiency of the user.

[0046] Further, the support plate 300 is provided with an exposed conductive part for contacting and conducting to an exposed conductive interface of the device body 800 in the first state, the conductive interface is electrically connected to the main control plate, and the battery is electrically connected to the conductive part. Understandably, when the support plate 300 is in the first state, that is, the support plate 300 is installed on the device body 800, the conductive part is in communication with the conductive interface. The communication between the exposed conductive part and the conductive interface provides a circuit channel for the battery and the main control plate, which realizes the charging requirement of the battery without the need for too many charging electronic elements, thereby saving the charging cost. Of course, in other embodiments, wireless charging can also be used to charge the battery.

[0047] Further, the touch panel further comprises an indicator light exposed to the touch panel 100, the indicator light is electrically connected to the battery and used for indicating the power of the battery. Understandably, the indicator light exposed to the surface of the touch panel 100 can intuitively reflect the power of the battery in the touch panel, so that the user can decide the use mode of the touch panel according to the power, and charge in time when the power is low, thereby improving the use experience and efficiency of the user.

[0048] Further, in the first state, the adjacent sides of the touch panels 100 of the two support plates 300 are spliced. Understandably, the same side of the two support plates 300 is provided with the touch panel 100, and the technical solution stipulates that the adjacent sides of the touch panels 100 are spliced, so that the touch panels 100 become a whole touch panel, eliminating the gap between the corresponding touch panels of the two support plates, thereby protecting the electronic elements such as sensors inside the touch panel from damage by dust, and also playing a role in beautifying the appearance.

[0049] Further, the touchpad further comprises a scroll wheel 600, in the first state, the sensor of the scroll wheel 600 is electrically connected to the main control board of the device body 800, in the second state, the sensor of the scroll wheel 600 is communicatively connected to the main control board; the scroll wheel 600 is located between the two sleeve joints 310 of the support plates 300, and is rotatably sleeved on the connecting shaft 500 and fixedly opposite to the connecting shaft 500 in the axial direction, in the second state, the scroll wheel 600 is arranged protruding outwardly relative to the touch panel 100. It can be understood that the scroll wheel 600 is arranged between the sleeve joints 310 of the two support plates 300 on the connecting shaft 500, and the scroll wheel 600 can rotate around the connecting shaft 500, and the scroll wheel 600 sensor connected to the main control board is arranged in the touchpad, so that the rotation movement of the scroll wheel 600 can also be recognized and processed by the main control board, improving the user's convenience and operation diversity. In the embodiment, the limiting structure is arranged on both sides of the scroll wheel 600 in the axial direction to limit the movement of the scroll wheel 600 in the axial direction, so that the scroll wheel 600 only has rotational movement, avoiding the misrecognition of the scroll wheel 600 sensor. It should be noted that when the touchpad is in the first state, the scroll wheel 600 should be stored inside the touchpad; when the touchpad is in the second state, the scroll wheel 600 should be arranged protruding outwardly relative to the touch panel 100, so that the user can directly touch the scroll wheel 600, thereby sending instructions to the main control board through the scroll wheel 600. In the embodiment, the touch panel 100 is provided with an avoiding slot 400, when the touchpad is in the first state, the scroll wheel 600 is stored in the avoiding slot 400, when the touchpad is in the second state, the scroll wheel 600 protrudes outwardly from the slot of the avoiding slot 400 relative to the touch panel 100. The touchpad in the embodiment further comprises a dust cover made of elastic material, when the touchpad is in the first state, the dust cover is engaged in the avoiding slot 400, since the avoiding slot 400 of the touchpad is connected to the inside and outside of the touchpad, there is a possibility that dust enters the inside of the touchpad from the outside, the arrangement of the dust cover prevents the dust from entering the inside of the touchpad. Since the dust cover is made of elastic material, when the two support plates 300 are relatively rotated, the dust cover can be easily pulled out of the avoiding slot 400 without damaging the structure of the touchpad.

[0050] Further, the connecting shaft 500 is provided with a mounting ring protrusion on each of the two axial sides of the roller 600, and the touchpad further comprises two reset springs 700, which are sleeved on the connecting shaft 500 on the opposite sides of the two mounting ring protrusions, and the two ends of each reset spring 700 are connected to the corresponding mounting ring protrusion and the sleeving part 310 of the support plate 300, respectively. Under the action of the reset spring 700, the support plate 300 has a tendency to maintain in the first position. It can be understood that in the embodiment, the limiting mechanism on the two axial sides of the roller 600 is the mounting ring protrusion, which limits the axial movement of the roller 600 on the connecting shaft 500, so that the position of the roller 600 in the axial direction is fixed. The side of the mounting ring protrusion facing the support plate 300 is provided with a reset spring 700, and the other end of the reset spring 700 is connected to the sleeving part 310 of the support plate 300. It can be understood that no matter the support plate 300 is in the second position or the first position, the reset spring 700 is always in a compressed state and will always generate a pushing force on the support plate 300 towards the bottom of the limiting groove 220, so that the limiting protrusion 320 of the support plate 300 is more stably pressed in the limiting groove 220, thereby increasing the stability of the support plate 300, and further making the touchpad not easy to disassemble when used by the user, thereby improving the user experience. Of course, in other embodiments, the same effect can also be achieved by the magnetic force generated by the magnetic attraction between the limiting groove 220 and the limiting protrusion 320.

[0051] Further, the opposite ends of the two fixing members 200 are provided with a guide ring groove 210, and the limiting groove 220 is recessed in the guide ring groove 210, and in the second position, the limiting protrusion 320 is slidably inserted into the guide ring groove 210. The setting of the guide groove will exert a circumferential limitation on the limiting protrusion 320 in the second position, so that the limiting protrusion 320 will move along the groove wall of the guide groove in the circumferential direction of the connecting shaft 500, and in the axial direction of the connecting shaft 500, only the switching between the first position and the second position can be performed, thereby reducing the possibility of other sliding of the limiting protrusion 320 in the second position, thereby improving the switching speed between the first position and the second position of the limiting protrusion 320, correspondingly saving the switching time of the user, improving the efficiency, and improving the use experience.

[0052] As Figure 5As shown, the application also proposes a notebook computer, which comprises a device main body 800 and a touchpad. The specific structure of the touchpad refers to the above-mentioned embodiments. Since the touchpad adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one. In the first state, the touchpad is installed on the device main body 800. In the second state, the touchpad is separated from the device main body 800 and can be used as a mouse independently of the device main body 800.

[0053] The above-mentioned is only the optional embodiment of the application, and does not limit the patent scope of the application.
