Description

Technical Field

[0001] This utility model relates to the field of laptop support technology, and more specifically, to a laptop with an extendable stand. Background Technology

[0002] Laptops are a powerful tool for modern people's work and study. Their slim and lightweight design combined with powerful performance allows for efficient work anytime, anywhere.

[0003] Existing laptops typically require a dedicated laptop bag or protective case when carried around to ensure the device is protected from impacts and scratches during transport.

[0004] However, users often face greater challenges in real-world usage scenarios, especially in outdoor environments such as construction sites, testing sites, and field investigations.

[0005] These locations often lack stable support surfaces, forcing users to place their computers directly on the ground, their knees, or other temporary supports to operate them. This not only affects work efficiency but may also lead to fatigue or equipment slippage and damage due to improper posture.

[0006] Furthermore, leg support can easily cause physical discomfort during prolonged use and makes it difficult to maintain a stable typing posture. These limitations severely restrict the flexibility and comfort of using laptops in outdoor settings. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] In view of the problems existing in the prior art, this utility model provides a laptop computer with an extendable stand to solve the technical problem mentioned in the background art of poor usability when carrying a laptop computer around.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A laptop computer with an extendable stand includes a laptop body, a bracket at the bottom of the laptop body, a mounting bracket hinged below the bracket, a flip-adjustment structure between the bracket and the mounting bracket, a base tray below the mounting bracket, two sets of first and second lifting rods between the base tray and the mounting bracket, the bottom ends of the first and second lifting rods being fixedly hinged to the inner wall of the base tray and the top ends being slidably hinged to the bottom end of the mounting bracket, a lifting adjustment structure between the first and second lifting rods, a protective cover at the top of the base tray, a flip-connection structure between the tail end of the protective cover and the base tray, and latches between the front and rear ends of the protective cover and the base tray.

[0012] The present invention is further configured such that the flip-connecting structure includes a connecting strip, one end of which is mounted on the outer side wall of the base box via a shaft and bearing. A sliding groove is provided on the side of the protective cover, and a sliding block is slidably installed in the sliding groove. The other end of the connecting strip is rotatably mounted on the sliding block via a shaft and bearing. The cooperation of the connecting strip, the sliding block, and the sliding groove allows the protective cover to be flipped relative to the base box. This facilitates opening the protective cover and flipping it to the bottom of the base box to achieve overall support, reduce the floor space occupied during use, and improve the flexibility of use.

[0013] The present invention is further configured such that the flip adjustment structure includes a connecting frame, which is rotatably mounted on the side of the bracket through the cooperation of a shaft and a bearing. The tail end of the connecting frame is provided with a first locking post, and the side of the mounting bracket is provided with a first guide groove. The tail end of the first locking post passes through the first guide groove and is threaded with a first locking knob. When the bracket is flipped to adjust the usage angle of the laptop body, flipping the bracket will cause the bracket to move and flip, thereby causing the first locking post connected to the connecting frame to move in the first guide groove. When the bracket moves to a suitable angle, the first locking knob is tightened to lock and fix the first locking post in the first guide groove. This allows the connecting frame, mounting bracket, and bracket to form a stable triangular support to support the laptop body during use, thus enabling flexible adjustment of the usage angle of the laptop.

[0014] The present invention is further configured such that the lifting adjustment structure includes a second locking pin, which is slidably mounted on the outside of the first lifting rod. A second guide groove is provided on the second lifting rod, and the second locking pin passes through the second guide groove and is threaded with a second locking knob. When the first lifting rod and the second lifting rod rotate relative to each other, the second lifting rod can drive the second locking pin to adjust synchronously along the second lifting rod under the action of the second guide groove, thereby realizing the synchronous relative flipping of the first lifting rod and the second lifting rod. In this way, the mounting frame supported by the first lifting rod and the second lifting rod can achieve flexible adjustment of the height. After adjusting to the appropriate position, the second locking knob is tightened, so that the second locking knob and the second locking pin cooperate to press and fix on the outside of the second lifting rod, thereby fixing the locking position of the second locking pin, and thus fixing the relative position of the first lifting rod and the second lifting rod, thereby achieving stable support and fixation of the mounting frame.

[0015] The present invention is further configured such that a sliding groove is provided on the outer side of the first lifting rod, and a slider is slidably disposed in the sliding groove. The second locking pin is installed on the outer side of the slider. The slider and the sliding groove enable the second locking pin to be slidably and adjustablely installed on the outer side of the first lifting rod. In this way, when the first lifting rod and the second lifting rod rotate relative to each other, the position of the second locking pin in the second guide groove can be flexibly adjusted, so as to achieve smooth rotation of the first lifting rod and the second lifting rod, thereby realizing the lifting and adjustment of the mounting bracket and enabling flexible adjustment of the height of the laptop during use.

[0016] The present invention is further configured such that two sets of limiting slide rods are symmetrically arranged at the bottom end of the mounting frame, and two sliding seats are symmetrically arranged on each set of limiting slide rods. The first lifting rod and the second lifting rod are hingedly installed at the bottom end of the corresponding sliding seats. The first lifting rod and the second lifting rod are slidably hinged at the bottom end of the mounting frame through the cooperation of the limiting slide rods and the sliding seats, thereby facilitating the lifting and adjusting of the mounting frame.

[0017] The present invention is further provided with a lifting handle at the front end of the protective cover, which facilitates lifting and carrying after the protective cover is fastened to the bottom tray box.

[0018] The present invention is further configured such that a limiting block is provided on the side of the bracket, and a support edge is provided at the front end of the bracket. Anti-slip pads are provided on the inner side walls of both the limiting block and the support edge. The limiting block enables the side mounting limit when the laptop body is placed on the bracket, and the support edge is used to support the bottom of the laptop body, thereby improving the stability of the laptop body when placed on the bracket.

[0019] The present invention is further configured such that two sets of cooling fans are symmetrically arranged on the bracket, which can enhance the heat dissipation effect of the bottom of the laptop body during use.

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the present invention provides a laptop computer with an extendable stand, which has the following advantages:

[0022] 1. Flexible multi-angle adjustment and stable support

[0023] This invention achieves flexible adjustment of the laptop's height and angle through the combined action of a flip-up adjustment structure and a height adjustment structure. A cross-type lifting rod design connects the mounting bracket and the base tray, and a locking knob allows for quick height fixation. The connecting bracket and guide groove structure between the tray and the mounting bracket allow for stepless adjustment and locking of the laptop's angle within a 0-80° range. This dual-adjustment structure not only accommodates the viewing needs of users of different heights but also provides stable support on uneven surfaces such as in the field or on construction sites. Compared to traditional lap-based operation, it effectively reduces neck and lumbar fatigue, improving comfort during extended work sessions.

[0024] 2. Integrated storage and portable protection

[0025] This invention utilizes a flip-up protective cover and a base tray to form a closed case structure. When stored, the entire extendable support can be hidden inside, and after being secured with latches, it forms a portable case only slightly thicker than a laptop. The protective cover employs a linkage flip mechanism of sliding blocks and connecting strips, which can be transformed into a support base when unfolded, saving floor space. Compared to traditional detachable stands and laptop bags, this design combines protection with portability, making it particularly suitable for outdoor workers who frequently work on the go.

[0026] 3. This utility model integrates dual cooling fans in the bracket, directly directing forced convection to the bottom of the laptop, solving the problem of reduced heat dissipation efficiency in stand mode. The anti-slip pads on the limiting blocks and support edges prevent the laptop from sliding and avoid scratching the metal frame. The pull handle and latch allow for one-handed opening and closing, while the unfolded triangular support structure uses force distribution to keep the center of gravity within the base tray, preventing tipping. These detailed designs significantly improve the safety and reliability of the device in complex environments while ensuring functionality. Attached Figure Description

[0039] Please see Figures 1-8 A laptop computer with an extendable stand includes a laptop body 2, a bracket 3 at the bottom of the laptop body 2, a mounting bracket 4 hinged below the bracket 3, a flip-adjustment structure between the bracket 3 and the mounting bracket 4, a base tray 5 below the mounting bracket 4, two sets of first lifting rods 6 and second lifting rods 7 between the base tray 5 and the mounting bracket 4, the bottom ends of the first lifting rods 6 and the second lifting rods 7 being fixedly hinged to the inner wall of the base tray 5, and the top ends being slidably hinged to the bottom end of the mounting bracket 4, a lifting adjustment structure between the first lifting rods 6 and the second lifting rods 7, a protective cover 8 at the top of the base tray 5, a flip-connection structure between the tail end of the protective cover 8 and the base tray 5, and a locking buckle 9 between the front and rear ends of the protective cover 8 and the base tray 5.

[0040] Please see Figures 1-8 As one embodiment of the flip-connection structure: The flip-connection structure includes a connecting strip 10. One end of the connecting strip 10 is installed on the outer side wall of the base tray 5 through the cooperation of a shaft and a bearing. A sliding groove 11 is provided on the side of the protective cover 8. A sliding block 12 is slidably installed in the sliding groove 11. The other end of the connecting strip 10 is rotatably installed on the sliding block 12 through the cooperation of a shaft and a bearing. Through the cooperation of the connecting strip 10, the sliding block 12 and the sliding groove 11, the protective cover 8 can be flipped relative to the base tray 5. This makes it easy to open the protective cover 8 and flip it to the bottom of the base tray 5 to achieve overall support, reduce the floor space occupied during use and improve the flexibility of use.

[0041] Please see Figures 1-8 As one implementation of the flip adjustment structure: The flip adjustment structure includes a connecting frame 13, which is rotatably mounted on the side of the bracket 3 through the cooperation of a shaft and a bearing. A first locking pin 14 is provided at the tail end of the connecting frame 13. A first guide groove 15 is provided on the side of the mounting bracket 4. The tail end of the first locking pin 14 passes through the first guide groove 15 and is threaded with a first locking knob 16. When the bracket 3 is flipped to adjust the usage angle of the laptop body 2, the bracket 3 is flipped, and the bracket 3 will drive the connecting frame 13 to move and flip, so that the first locking pin 14 connected to the connecting frame 13 will move in the first guide groove 15. When the bracket 3 moves to a suitable angle, the first locking knob 16 is tightened to lock the first locking pin 14 in the first guide groove 15. Thus, the connecting frame 13, the mounting bracket 4 and the bracket 3 can form a triangular stable support to support the laptop body 2 during use. In this way, the usage angle of the laptop can be flexibly adjusted during use.

[0042] Please see Figures 1-8As one implementation of the lifting adjustment structure: the lifting adjustment structure includes a second locking pin 17, which is slidably mounted on the outside of the first lifting rod 6. A second guide groove 18 is provided on the second lifting rod 7. The second locking pin 17 passes through the second guide groove 18 and is threaded with a second locking knob 19. When the first lifting rod 6 and the second lifting rod 7 rotate relative to each other, the second lifting rod 7 can drive the second locking pin 17 to adjust synchronously along the second lifting rod 7 under the action of the second guide groove 18. This allows the first lifting rod 6 and the second lifting rod 7 to rotate synchronously relative to each other. In this way, the mounting frame 4 supported by the first lifting rod 6 and the second lifting rod 7 can be flexibly adjusted in height. After adjusting to the appropriate position, the second locking knob 19 is tightened, so that the second locking knob 19 and the second locking pin 17 cooperate to press and fix on the outside of the second lifting rod 7, thereby fixing the locking position of the second locking pin 17, and thus fixing the first lifting rod 6 and the second lifting rod 7 relative to each other, thereby achieving stable support and fixation of the mounting frame 4.

[0043] Please see Figures 1-8 As one embodiment of the first lifting rod 6: a sliding groove 20 is provided on the outer side of the first lifting rod 6, and a slider 21 is slidably arranged in the sliding groove 20. The second locking pin 17 is installed on the outer side of the slider 21. Through the arrangement of the slider 21 and the sliding groove 20, the second locking pin 17 can be slidably and adjustablely installed on the outer side of the first lifting rod 6. In this way, when the first lifting rod 6 and the second lifting rod 7 rotate relative to each other, the position of the second locking pin 17 in the second guide groove 18 can be flexibly adjusted, so as to achieve smooth rotation of the first lifting rod 6 and the second lifting rod 7, thereby realizing the lifting and adjustment of the mounting bracket 4, and realizing the flexible adjustment of the height of the laptop when in use.

[0044] Please see Figures 1-8 As one embodiment of the mounting frame 4: two sets of limiting slide rods 22 are symmetrically arranged at the bottom end of the mounting frame 4. Each set of limiting slide rods 22 is symmetrically arranged with two sliding seats 23. The first lifting rod 6 and the second lifting rod 7 are hinged to the bottom end of the corresponding sliding seat 23. The first lifting rod 6 and the second lifting rod 7 are slidably hinged at the bottom end of the mounting frame 4 through the cooperation of the limiting slide rods 22 and the sliding seats 23, thereby facilitating the lifting and adjusting of the mounting frame 4.

[0045] Please see Figures 1-8 As one implementation of the protective cover 8: the front end of the protective cover 8 is provided with a lifting handle 24, which facilitates the lifting and carrying of the protective cover 8 after it is fastened to the bottom tray box 5.

[0046] Please see Figures 1-8As one implementation of the bracket 3: a limiting block 25 is provided on the side of the bracket 3, and a support edge 26 is provided at the front end of the bracket 3. Anti-slip pads are provided on the inner side walls of the limiting block 25 and the support edge 26. The limiting block 25 realizes the side installation limitation when the laptop body 2 is placed on the bracket 3. The support edge 26 is used to support the bottom of the laptop body 2, thereby improving the stability of the laptop body 2 when placed on the bracket 3. Two sets of cooling fans 27 are symmetrically arranged on the bracket 3, which can enhance the bottom heat dissipation effect of the laptop body 2 during use.

[0047] In summary:

[0048] In use, the present invention is to open the latch 9 and flip the protective cover 8. Under the action of the connecting strip 10, the sliding groove 11 and the sliding block 12, the protective cover 8 is first moved backward relative to the bottom tray box 5 to a suitable distance, and then the connecting strip 10 is driven to flip upward and backward, so that the protective cover 8 is flipped over. Then, the protective cover 8 is placed at the bottom of the bottom tray box 5, so that it can be used for overall support.

[0049] When in use, the mounting bracket 4 can be moved upward. During this process, the upward movement of the mounting bracket 4 will drive the limit slide rod 22 to move upward, thereby causing the two sets of sliding seats 23 on the limit slide rod 22 to move upward. The two sets of sliding seats 23 will move relative to each other due to the lateral pulling force of the first lifting rod 6 and the second lifting rod 7.

[0050] At the same time, the first lifting rod 6 and the second lifting rod 7 will flip upward due to the upward pulling force of the sliding seat 23, thereby realizing the height adjustment of the mounting bracket 4;

[0051] During this process, the second locking pin 17 will slide relative to the first lifting rod 6 under the cooperation of the slider 21 and the slide groove 20. At the same time, under the action of the second guide groove 18, it will slide relative to the second lifting rod 7. After adjusting to a suitable height, tighten the second locking knob 19 to lock the second locking pin 17 in the second guide groove 18. Here, the second locking knob 19 presses the second lifting rod 7, and the slider 21 will press the inner wall of the slide groove 20, thereby locking the slider 21 in the slide groove 20.

[0052] In this way, the locking and fixing between the first lifting rod 6 and the second lifting rod 7 can be achieved, thereby achieving stable support for the mounting bracket 4 and enabling flexible adjustment and locking and fixing of the height of the laptop body 2 during use.

[0053] Then, the bracket 3 is flipped, which will cause the connecting frame 13 to move and flip, so that the first locking pin 14 connected to the connecting frame 13 will move in the first guide groove 15.

[0054] When the bracket 3 moves to the appropriate angle, tighten the first locking knob 16 to lock the first locking pin 14 in the first guide groove 15, so that the connecting bracket 13, the mounting bracket 4 and the bracket 3 can form a triangular stable support to support the laptop body 2 when in use. In this way, the laptop can be used with flexible adjustment of the angle, so that the laptop body 2 can be unfolded and used flexibly.

[0055] After use, the above steps can be reversed to completely store the laptop body 2 carrying bracket 3, mounting bracket 4, first lifting rod 6, second lifting rod 7 and other components into the bottom tray box 5. After the protective cover 8 is snapped onto the bottom tray box 5 in reverse, it is locked and fixed by the latch 9, so that the protective cover 8 and the bottom tray box 5 form a box structure to protect the laptop body 2 when it is carried.

[0056] In all the solutions mentioned above, the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
