Description

Technical Field

[0001] The invention relates to the technical field of supporting foot pads, and in particular to a foot pad linkage mechanism and a notebook computer. Background Art

[0002] There are many products in our daily life that are composed of two parts, and the two parts are hinged by a hinge located at the edge. Some of these products are equipped with foot pads at the bottom to provide support. For example, a laptop computer is equipped with foot pads at the rear of its bottom, which provide support and increase the height of the rear of the laptop through the foot pads to ensure heat dissipation.

[0003] Existing laptops generally use foot pads that are directly fixed to the bottom. If the height of the foot pad needs to be increased to improve the air intake efficiency of the fan, the thickness of the foot pad can only be simply increased, which makes the notebook look bulky and damages the appearance of the notebook. There is also a push-push type liftable foot pad, which is manually pressed to extend the foot pad to increase the height of the foot pad. This foot pad requires manual operation, is inconvenient to use, and has a poor user experience. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the laptop computer foot pad in the prior art requires manual deliberate operation and is inconvenient to use, thereby providing a foot pad linkage mechanism that can extend the foot pad when the computer cover is opened.

[0011] The transmission assembly is suitable for realizing the synchronous rotation of the product hinge shaft and the rotating shaft.

[0012] Optionally, the linkage slot / hole is also extended to form a retaining slot / hole, which is arc-shaped and has the same diameter as the trajectory of the linkage shaft rotating around the rotating shaft. When the linkage shaft runs to the position where the linkage slot / hole and the retaining slot / hole are connected, the retaining slot / hole is coaxial with the rotating shaft.

[0013] Optionally, the rotating cantilever is perpendicular to the rotating shaft, and the linkage shaft is parallel to the rotating shaft.

[0031] A foot pad bracket is fixed on the bottom surface of the rotating block, and a receiving groove is provided on the bottom surface of the foot pad bracket;

DETAILED DESCRIPTION

[0051] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. 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.

[0052] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0053] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0055] The following is a detailed description taking the application on a laptop computer as an example.

[0056] Combination Figure 1-Figure 2 As shown, an embodiment of the present invention provides a foot pad linkage mechanism, including a fixing frame 1, a rotating shaft 2, a rotating cantilever 3, a linkage shaft 4, a rotating block 5 and a transmission assembly 6.

[0057] The main function of the fixing frame 1 is to support other components. When in use, the fixing frame 1 can be fixed to the inner side of the bottom of the notebook computer. The specific structure of the fixing frame 1 is not limited and can be designed according to the internal space of the notebook computer and the position of the components to be supported.

[0058] The rotating shaft 2 is rotatably mounted on the fixed frame 1. Specifically, the rotatable mounting can be realized by using a bearing, or a clearance fit plus an axial limit structure, such as Figure 1 As shown in , the rotating shaft 2 is inserted into the fixing frame 1, and the two ends are provided with stoppers to limit the axial position of the rotating shaft 2. The cross-sectional shape of the rotating shaft 2 is not limited, and can be circular, or Figure 1 The structure is formed by cutting a circle symmetrically into two parts. The main purpose of the latter is to facilitate the circumferential limitation of the parts installed thereon.

[0059] The rotating cantilever 3 has one end fixed on the rotating shaft 2 and the other end extending to one side of the rotating shaft 2. The specific shape of the rotating cantilever 3 is not limited, and can be a straight line shape or a curved line shape, and the former is preferably adopted. The rotating cantilever 3 is preferably perpendicular to the rotating shaft 2. In other embodiments, the angle between the rotating cantilever 3 and the rotating shaft 2 can also be an acute angle or an obtuse angle, as long as it can meet the requirements of extending laterally to the rotating shaft 2. The so-called one side of the rotating shaft 2 is the radial outer side of the rotating shaft 2.

[0060] The linkage shaft 4 is located at the other end of the rotating cantilever 3 and at one side of the rotating cantilever 3 in the direction of the rotating shaft 2. The linkage shaft 4 is fixedly connected or integrally formed or rotatably connected to the rotating cantilever 3. The specific structure of the linkage shaft 4 is not limited, as long as it can be placed in the linkage slot / hole 51 and can slide.

[0061] The rotating block 5 is suitable for installing the foot pad 9. The rotating block 5 is located on one side of the rotating cantilever 3 in the direction of the rotating shaft 2 and on the same side as the linkage shaft 4. The rotating block 5 is rotatably connected to the fixed frame 1 and the rotating axis is parallel to the rotating shaft 2. The surface of the rotating block 5 close to the rotating cantilever 3 is provided with a linkage groove / hole 51. The linkage shaft 4 is placed in the linkage groove / hole 51, and the linkage groove / hole 51 is suitable for realizing the unidirectional rotation of the rotating block 5 when the rotating shaft 2 rotates unidirectionally. The specific shape of the linkage groove / hole 51 is not limited, and can be Figure 2 The linear groove structure in the embodiment can also be a curved groove structure that is inconsistent with the running track of the linkage shaft 4. The former is preferably adopted, and the structural design is simpler and the linkage effect is more reliable. Of course, the linkage direction here should ensure that in actual use, the foot pad 9 rotates outward synchronously during the process of opening the computer cover, thereby increasing the height of the foot pad 9.

[0062] The transmission assembly 6 is suitable for realizing the synchronous rotation of the product hinge shaft 7 and the rotating shaft 2. Specifically, it can be a chain sprocket transmission structure, or a gear transmission structure, or a synchronous belt transmission mechanism with inner teeth.

[0063] When working, the computer cover is opened to drive the hinge shaft 7 to rotate, the hinge shaft 7 drives the rotating shaft 2 to rotate through the transmission assembly 6, the rotating shaft 2 drives the rotating cantilever 3 to rotate, thereby driving the linkage shaft 4 to rotate around the rotating shaft 2. Since the linkage shaft 4 is placed in the linkage slot / hole 51, and the rotating block 5 is rotatably connected to the fixing frame 1, the rotating block 5 will rotate in a passive manner, thereby increasing the height of the foot pad 9. The foot pad linkage mechanism of this embodiment has a linkage design for the foot pad 9 and the hinge shaft 7 of the product. When the hinge shaft 7 rotates, the height of the foot pad 9 can be synchronously increased, without manual operation, which is more convenient; and in the non-working state, the foot pad 9 is retracted, so that the thickness of the foot pad 9 is not too thick, taking into account the aesthetic requirements of the product.

[0064] Reference Figure 2As an improvement on the above scheme, the linkage slot / hole 51 is further extended to form a retaining slot / hole 52. The retaining slot / hole 52 is arc-shaped and has the same diameter as the trajectory of the linkage shaft 4 rotating around the rotating shaft 2. When the linkage shaft 4 runs to the position where the linkage slot / hole 51 and the retaining slot / hole 52 are connected, the retaining slot / hole 52 is coaxial with the rotating shaft 2. During operation, the linkage shaft 4 first drives the rotating block 5 to rotate through the linkage slot / hole 51, and then is placed in the retaining slot / hole 52 to maintain the protruding height of the foot pad 9. Before the computer cover is fully opened, the linkage shaft 4 has already passed the linkage slot / hole 51 and entered the retaining slot / hole 52. In this way, the linkage of the foot pad 9 caused by accidental touching of the computer cover is avoided, and the user experience is better. For example, Figure 5 The diagram shows a state where the linkage shaft 4 is in a position where the linkage slot / hole 51 and the retaining slot / hole 52 are connected. In this state, the computer cover is rotated 60°. Figure 6 The diagram shown is a normal working state diagram, in which the linkage shaft 4 is placed at the end position of the retaining groove / hole 52, and the computer cover is rotated 135° in this state.

[0065] Reference Figure 1 As a preferred solution of the above solution, the rotating cantilever 3 is perpendicular to the rotating shaft 2, and the linkage shaft 4 is parallel to the rotating shaft 2. The structure is simple and the installation is convenient.

[0066] Reference Figure 3 , as a preferred structure of the linkage shaft 4, including:

[0067] A fixed shaft 41 is vertically fixed to the other end of the rotating cantilever 3;

[0068] The rotating drum 42 is sleeved on the fixed shaft 41 and is located in the linkage slot / hole 51. In order to prevent the rotating drum 42 from falling off the fixed shaft 41, a limiting member can be added to the end of the fixed shaft 41 to limit the rotating drum 42 axially.

[0069] During operation, the rotating drum 42 is placed in the linkage groove / hole 51. When relative movement occurs, the rotating drum 42 contacts the linkage groove / hole 51 in a rolling manner, which can reduce friction and make the adjustment of the foot pad 9 smoother.

[0070] Reference Figure 1 , as a preferred structure of the fixing frame 1, comprising:

[0071] A fixed bracket 11, in which the rotating shaft 2 is installed;

[0072] The mounting frame 12 , in which the rotating block 5 is mounted.

[0073] During installation, the fixing bracket 11 and the mounting bracket 12 are fixed to the bottom of the computer respectively, and then the shaft 2 and the rotating block 5 are respectively installed on the fixing bracket 11 and the mounting bracket 12. Compared with the integral fixing bracket 1, on the one hand, because the shaft 2 and the rotating block 5 are separated by a certain distance, the preferred split structure does not need to occupy the area between the shaft 2 and the rotating block 5, thus reducing the space occupation; on the other hand, the independent installation is more convenient.

[0074] Reference Figure 4 As a preferred structure of the transmission assembly 6, the transmission assembly 6 is a gear set, specifically comprising:

[0075] The driving gear 61 is adapted to be mounted and fixed on the hinge shaft 7 of the product;

[0076] The transmission gear 62 is provided with at least one and is rotatably mounted on the fixed bracket 11; the specific number is designed according to the position of the rotating shaft 2. When it is an odd number, the hinge shaft 7 rotates in the same direction as the rotating shaft 2, and when it is an even number, the hinge shaft 7 rotates in the opposite direction as the rotating shaft 2. For example Figure 1 In the middle are two transmission gears 62;

[0077] The driven gear 63 is sleeved and fixed on the rotating shaft 2;

[0078] The driving gear 61 , the transmission gear 62 and the driven gear 63 are meshed and connected in sequence.

[0079] During operation, the hinge shaft 7 rotates to drive the driving gear 61 to rotate integrally, the driving gear 61 drives the transmission gear 62 to rotate, the transmission gear 62 drives the driven gear 63 to rotate, and the transmission gear 62 drives the rotating shaft 2 to rotate integrally, thereby driving the rotation of the rotating cantilever 3 and the linkage shaft 4, and then realizing the height adjustment of the rotating block 5 through the linkage slot / hole 51.

[0080] As a preferred solution of the gear set, the driving gear 61, the transmission gear 62 and the driven gear 63 have the same diameter, so that the hinge shaft 7 and the rotating shaft 2 have the same rotation speed, that is, the rotation angle of the hinge shaft 7 is equal to the rotation angle of the rotating shaft 2.

[0081] Reference Figure 1 As a preferred structure of the fixed bracket 11, the fixed bracket 11 includes two fixed plates parallel to each other, the gear set is located between the two fixed plates, one end of the rotating shaft 2 extends outward from the area between the two fixed plates to form an extension, and the rotating cantilever 3 is fixed on the extension. The structure is simple and the space layout is more reasonable.

[0082] Reference Figure 7 The embodiment of the present invention provides a laptop computer, comprising a computer body and a computer cover, wherein the computer body and the computer cover are connected via a hinge 7, and further comprising:

[0083] The foot pad linkage mechanism, as described above, the fixing frame 1 is fixed to the bottom of the computer body;

[0084] The foot pad 9 is fixed on the bottom surface of the rotating block 5 .

[0085] During operation, the computer cover is opened manually to rotate the hinge shaft 7, and the hinge shaft 7 drives the rotating shaft 2 to rotate through the transmission mechanism, thereby driving the rotating cantilever 3 and the linkage shaft 4 to rotate around the rotating shaft 2. Since the linkage shaft 4 is placed in the linkage groove / hole 51, the rotating block 5 rotates passively, thereby realizing the adjustment of the height of the foot pad 9.

[0086] Reference Figure 8 , as a preferred solution of the foot pad 9, including:

[0087] The foot pad bracket 81 is fixed to the bottom surface of the rotating block 5, and a receiving groove is provided on the bottom surface of the foot pad bracket 81; the foot pad bracket 81 is preferably fixed to the bottom surface of the rotating block 5 by bolts, and of course, it can also be fixed by welding, snapping, pasting or other methods;

[0088] The foot pad 82 is embedded and fixed in the receiving groove. The foot pad 82 is generally made of a flexible material to avoid damage on the one hand, and on the other hand, it contacts the support surface in a soft-hard contact manner instead of a hard-hard contact manner, which can increase friction and provide a more stable support. The foot pad 82 can be fixed in the foot pad bracket 81 by means of a bayonet, adhesive, etc.

[0089] It should be noted that the hinge shaft 7 of the laptop computer has a built-in locking function, which can fix the computer cover at any rotation position. This provides a guarantee for the stability of the entire foot pad linkage mechanism, and there will be no situation where the rotating block 5 as an active component drives the screen to rotate in reverse due to the notebook's own gravity, thereby ensuring the user experience.

[0090] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
