Description

Technical Field

[0001] The invention relates to the technical field of notebook computer attachment devices, and in particular to a foot pad structure and a notebook computer. Background Art

[0002] With the development of science and technology, the popularity and usage rate of laptops are getting higher and higher, and there are more and more usage scenarios, including but not limited to messy desktops, soft beds, log benches, lush lawns in the suburbs, etc.

[0003] The foot pad structure design of existing laptops is generally designed to be shorter for the sake of aesthetics, which can only meet the usage requirements on a general desktop, but ignores the usage scenario requirements of other parts; for example, the usage scenario requirements on a special-shaped surface.

[0004] In the prior art, when a laptop is placed on a reference plane supporting the laptop, it is impossible to ensure that it is in a horizontal state, that is, the posture of the laptop cannot be adjusted in real time, making it difficult to achieve an effect of viewing the screen horizontally, thereby reducing the user experience.

[0005] Generally speaking, the foot pad structure is usually set on the outer shell of a laptop computer (the outer shell at least includes: a D shell (that is, a first shell) and a C shell (that is, a second shell); wherein, the D shell is located at the bottom of the laptop computer, also known as the bottom shell surface or the rear shell surface; the D shell mainly serves as the bottom support structure of the laptop computer, and is usually provided with bottom fixing screws for fixing several functional components, and is also provided with heat dissipation holes for dissipating heat generated by several functional components; in addition, the C shell is located on the surface where the keyboard and touchpad are located, also known as the keyboard surface).

[0006] It is further explained that in order to ensure the heat dissipation effect, the height of the existing foot pad structure is only suitable for being placed on a relatively flat desktop; this means that when the user encounters a tilted desktop while working outside, the laptop computer will be placed with a crooked screen (the crooked screen means that the user cannot look directly at the screen horizontally); or when used in bed, the bed sheet will block the air inlet, resulting in poor heat dissipation effect of the laptop computer.

[0066] See also Figure 1-Figure 7 The foot pad structure 100 is used in conjunction with a notebook computer 200 having a first shell 2001 .

[0067] The foot pad structure 100 comprises a first toothed member 1 , a first foot pad arm 2 , a second foot pad arm 3 , a second toothed member 4 and a driving component 5 .

[0068] A portion of the first toothed member 1 is provided with a plurality of first meshing teeth 1201 , and another portion is fixedly mounted on the first housing 2001 .

[0069] In addition, a receiving space 2101 is formed inside the first foot pad arm 2 ; any end of the first foot pad arm 2 is hinged to the first toothed member 1 , so that the first foot pad arm 2 can rotate relative to the first toothed member 1 .

[0070] In addition, a receiving slot 301 is formed on the second foot pad arm 3 ; the second foot pad arm 3 is hinged to the other end of the first foot pad arm 2 , so that the first foot pad arm 2 can enter or leave the receiving slot 301 .

[0071] Specifically, the second toothed member 4 is hinged to the first foot pad arm 2 and is accommodated in the accommodating space 2101 ; the second toothed member 4 is provided with a plurality of second meshing teeth 401 matched with the first meshing teeth 1201 .

[0072] It should be noted that the driving component 5 is accommodated in the accommodating space 2101 ; at least a portion of the driving component 5 may be connected to the second toothed component 4 to drive the second toothed component 4 to rotate.

[0073] It can be understood that, through the mutual meshing between the first meshing teeth 1201 and the second meshing teeth 401 , the first foot pad arm 2 can follow the rotation of the second tooth-shaped member 4 to move away from or approach the first housing 2001 .

[0074] In some embodiments, Figure 4 and Figure 5 As shown, the first foot pad arm 2 includes a foot pad arm body 21 , a cover plate 22 and a gasket 23 .

[0075] In the embodiment of the present application, the foot pad arm body 21 is provided with an opening 2102 in the height direction 1001 so that the second toothed member 4 and the driving member 5 enter the accommodating space 2101 from the opening 2102 ; in other words, the accommodating space 2101 is connected with the outside of the foot pad arm body 21 through the opening 2102 .

[0076] To further explain, a pair of mounting grooves 2103 are disposed at two opposite ends of the foot pad arm body 21 in the length direction 1002 .

[0077] The cover plate 22 is disposed on the opening 2102 of the foot pad arm body 21 to enclose and form a receiving space 2101 .

[0078] In addition, the gasket 23 is received in any one of the mounting grooves 2103 , and the first toothed member 1 is located in another mounting groove 2103 to form a closed accommodation space 2101 .

[0079] In some embodiments, in combination Figure 4 and Figure 5 It can be seen that a pair of mounting portions 211 are provided on both sides of the foot pad arm body 21 in the width direction 1003 .

[0080] Specifically, the second tooth-shaped member 4 is located between the pair of mounting portions 211 , and the axis direction of the second tooth-shaped member 4 is parallel to the width direction 1003 of the foot pad arm body 21 .

[0081] In some embodiments, according to Figure 4-Figure 6 It can be known that the first toothed member 1 includes a base portion 11 and a meshing portion 12 .

[0082] It can be understood that one end of the base portion 11 abuts against the surface of the first shell 2001 , and the other end is connected to the meshing portion 12 .

[0083] It should be noted that the meshing portion 12 has an arc surface (not shown in the figure), and a plurality of first meshing teeth 1201 are arranged on the arc surface at a preset target interval.

[0084] In the embodiment of the present application, the cross-sectional shape of the base portion is rectangular, and the cross-sectional shape of the meshing portion is semicircular; the above cross-sectional shape is perpendicular to the thickness direction of the first toothed member 1, and the thickness direction of the first toothed member 1 is parallel to the width direction 1003 of the foot pad arm body 21.

[0085] In some embodiments, Figure 4 and Figure 5 It can be seen that the foot pad structure 100 further includes: a first pivot 6 , a second pivot 7 and a third pivot 8 .

[0086] The first pivot 6 , the second pivot 7 and the third pivot 8 all extend along the width direction 1003 of the foot pad arm body 21 .

[0087] In addition, the first pivot 6 passes through the first toothed member 1 and is fixedly mounted on the foot pad arm body 21 , so that the foot pad arm body 21 can rotate relative to the first toothed member 1 .

[0088] In addition, the second toothed member 4 is fixedly mounted on the second pivot 7 , and two ends of the second pivot 7 are respectively connected to a pair of mounting portions 211 .

[0089] Specifically, the third pivot 8 passes through the gasket 23 and the foot pad arm body 21 , and the second foot pad arm 3 is sleeved on two ends of the third pivot 8 , so that the second foot pad arm 3 can rotate relative to the first foot pad arm 2 .

[0090] It is further explained that the above-mentioned first pivot 6, second pivot 7 and third pivot 8 can all achieve a supporting function; wherein, the first pivot 6 can serve as a support for the end of the foot pad arm body 21 located at the first tooth-shaped part 1; in addition, the second pivot 7 can serve as a support for the second tooth-shaped part 4; furthermore, the third pivot 8 can serve as a support for the end of the second foot pad arm 3 hinged to the foot pad arm body 21 away from the first tooth-shaped part 1.

[0091] Figure 8 A schematic diagram of the structure of a drive motor provided in an embodiment of the present invention.

[0092] In some embodiments, reference Figure 4 and Figure 8 It can be seen that the driving component 5 includes: a driving motor 51 .

[0093] In the embodiment of the present application, the driving motor 51 has a protruding shaft 511 ; the driving motor 51 is provided with a third toothed member 512 at the end of the protruding shaft 511 , and the third toothed member 512 has a cylindrical surface.

[0094] To further explain, a plurality of third meshing teeth 5121 are disposed on the cylindrical surface, and the plurality of third meshing teeth 5121 are arranged along the circumferential direction of the third tooth-shaped member 512 at a preset target spacing.

[0095] Specifically, the driving motor 51 can be an electric motor, which makes the foot pad structure 100 an electric foot pad.

[0096] In some embodiments, please refer to Figure 7 A plurality of fourth meshing teeth 402 are provided on any end surface of the second toothed member 4 in the axial direction; the plurality of fourth meshing teeth 402 are arranged along the circumference of the second toothed member 4 at a preset target distance and enclosed to form a ring.

[0097] Fig. 9 A schematic structural diagram of a transmission shaft provided in an embodiment of the present invention.

[0098] In some embodiments, see Figure 4 , Figure 8 and Fig. 9 The driving component 5 also includes: a transmission shaft 52.

[0099] The two ends of the transmission shaft 52 are respectively provided with a fifth meshing tooth 5201 and a sixth meshing tooth 5202 ; the fifth meshing tooth 5201 and the sixth meshing tooth 5202 both protrude from the axial surface of the transmission shaft 52 at a preset interval along the circumference of the transmission shaft 52 .

[0100] In addition, the fifth meshing teeth 5201 and the third meshing teeth 5121 mesh with each other to drive the transmission shaft 52 to rotate; the sixth meshing teeth 5202 and the fourth meshing teeth 402 mesh with each other to drive the second toothed member 4 to rotate.

[0101] In some embodiments, see Figure 1-Figure 4 The foot pad structure 100 can be switched between a stowed state and an unfolded state to change the distance between the first shell 2001 and the reference plane supporting the laptop computer 200 .

[0102] It should be noted that when the foot pad structure 100 is in the storage state, the first foot pad arm 2 enters the receiving groove 301 , and the first foot pad arm 2 and the second foot pad arm 3 both abut against the surface of the first shell 2001 .

[0103] It is understandable that when the foot pad structure 100 is switched to the unfolded state, the first foot pad arm 2 is separated from the receiving slot 301 , and the end of the first foot pad arm 2 facing away from the first tooth-shaped member 1 is away from the first shell 2001 .

[0104] Generally speaking, when the foot pad structure 100 is in the storage state, it is convenient for the user to store the laptop computer 200 in the storage bag. In this case, the volume and occupied space of the laptop computer 200 need to be reduced.

[0105] Furthermore, when the foot pad structure 100 is in the unfolded state, it is convenient for the user to place the laptop computer 200 on the above-mentioned reference plane. In this case, the distance between the laptop computer 200 and the reference plane needs to be increased to ensure the heat dissipation effect of the laptop computer 200.

[0106] like Figure 1-Figure 4 As shown, the laptop computer 200 at least includes: a level sensor (not shown in the figure), several functional modules (not shown in the figure), a first shell 2001 and a second shell (not shown in the figure).

[0107] Generally speaking, the first shell 2001 is the D shell of the laptop computer, and the second shell is the C shell of the laptop computer; the D shell is located at the bottom of the laptop computer, also known as the bottom shell surface or the rear shell surface; the D shell mainly serves as the bottom support structure of the laptop computer, and is usually provided with bottom fixing screws for fixing several functional components, and heat dissipation holes for dissipating heat generated by several functional components; in addition, the C shell is located on the surface where the keyboard and touchpad are located, also known as the keyboard surface.

[0108] Specifically, the first shell 2001 and the second shell are connected to form a receiving space (not shown in the figure); the level sensor and several functional modules are arranged in the receiving space.

[0109] At least four of the above-mentioned foot pad structures 100 are arranged at the four corners of the first shell 2001 .

[0110] In addition, the second foot pad arm 3 of the foot pad structure 100 can be adjusted according to the level sensor so that the laptop computer 200 can be placed horizontally on the reference plane supporting the laptop computer 200 .

[0111] It is further explained that the level sensor can generate real-time data information (which can display the posture of the laptop computer). After the first foot pad arm 2 is fully unfolded, the user can adjust the posture of the laptop computer in real time according to the data information generated by the level sensor to achieve the effect of looking directly at the screen horizontally, thereby enhancing the user's experience.

[0112] Compared with the traditional foot pad structure, the foot pad structure 100 is not only suitable for a relatively flat table top, but also has a wider range of usage scenarios (that is, the foot pad structure 100 can be suitable for special-shaped surfaces), including but not limited to: messy table tops, soft beds, log benches and lush lawns in the suburbs.

[0113] Moreover, compared with the traditional foot pad structure, the foot pad structure 100 has the advantages of simple structure, compact structure, easy operation and beautiful appearance.

[0114] It can be understood that when the user is working outside and encounters a tilted desktop, the foot pad structure 100 can ensure that the laptop computer 200 will not be placed with the screen tilted; or when the user is using it in bed, the foot pad structure 100 prevents the air inlet of the laptop computer 200 from being blocked by the bed sheet, thereby improving the heat dissipation effect of the laptop computer 200, thereby avoiding the situation where the CPU (Central Processing Unit) cannot operate due to heat accumulation.

[0115] Fig.10 The steps of switching the foot pad structure provided by the embodiment of the present invention to the unfolded state are shown.

[0116] Combination Figure 1-Figure 10 , the unfolded state of the foot pad structure 100 is described in detail, including but not limited to the following steps:

[0117] S10, the user first bends the second foot pad arm 90 degrees away from the first shell.

[0118] S20, the driving motor starts to work to drive the transmission shaft to rotate.

[0119] S30, the second toothed member can rotate along with the rotation of the transmission shaft, and the first foot pad arm is driven to move in a direction away from the first housing through the mutual engagement between the second toothed member and the first toothed member.

[0120] S40: The user adjusts the second foot pad arm according to the level sensor to ensure that the user can look directly at the screen horizontally.

[0121] S50: After the second foot pad arm is adjusted to a suitable state, the foot pad structure is unfolded.

[0122] In summary, the foot pad structure and the laptop provided by the embodiment of the present invention are designed by adding a first toothed part, a first foot pad arm, a second foot pad arm, a second toothed part and a driving component; wherein, a receiving space is formed inside the first foot pad arm, and a receiving groove is provided on the second foot pad arm; in addition, the first foot pad arm can enter or leave the receiving groove, and the second toothed part and the driving component are both accommodated in the receiving space; in addition, through the mutual engagement between the first toothed part and the second toothed part, the first foot pad arm follows the rotation of the second toothed part and moves away from or close to the first shell; in summary, the foot pad structure can be used on a special-shaped surface, while ensuring the heat dissipation performance of the laptop, so that the foot pad structure is not only suitable for a relatively flat desktop, but also increases the use scenarios of the foot pad structure; and the foot pad structure also has the advantages of simple structure, compact structure, simple operation and beautiful appearance. By integrating a level sensor inside the laptop, the second foot pad arm can be adjusted according to the level sensor, so as to achieve the purpose of adjusting the posture of the laptop in real time, so as to achieve the effect of looking directly at the screen horizontally, thereby increasing the user experience. Therefore, the foot pad structure applicable to the notebook computer provided by the embodiment of the present invention has certain novelty compared with the traditional foot pad structure applicable to the notebook computer.

[0123] The above contents are further detailed descriptions of the present invention in combination with specific / preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
