Description

Technical Field

[0001] This invention relates to the technical field of laptop computer support stands, and particularly to an accessory for supporting laptop computers. Background Technology

[0002] With the increasing use of laptops, poor heat dissipation can lead to sluggish computer operation or even crashes. When a laptop gets very hot, the system will automatically reduce its frequency or operating speed to reduce heat and protect components from overheating and burning out. When using a laptop, people often need to use a laptop stand for different usage situations, and the requirements for laptop stands are also getting higher and higher. Laptop stands need to meet ergonomic requirements while also protecting the laptop. In addition to stable support and precise adjustment, laptops also need good heat dissipation.

[0003] A laptop stand, disclosed in publication number "CN107504332B", presents the following technical solution: The laptop stand includes: a support plate adapted to be mounted on a desktop; a laptop placement assembly switchable between an unfolded and folded state, the laptop placement assembly including: a placement plate, the lower end of which is slidably placed on the desktop, the laptop adapted to be placed on the placement plate; and a connecting rod having a first end and a second end, the first end being rotatably connected to the upper end of the placement plate, and the second end being rotatably connected to the support plate. When the laptop placement assembly is in the unfolded state, the second end of the connecting rod is away from the placement plate; when the laptop placement assembly is in the folded state, the second end of the connecting rod is close to the placement plate. However, while this laptop stand allows for heat dissipation during height adjustment, it cannot simultaneously clean the heat dissipation device, easily leading to dust accumulation, which affects fan rotation and thus the heat dissipation effect.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention. Example 1:

[0032] This invention provides an accessory for supporting a laptop computer, such as... Figure 1 As shown, it includes a support frame, which includes a chassis 1. A fixed bracket 2 is fixedly installed on the upper surface of the chassis 1. The end of the fixed bracket 2 away from the chassis 1 is rotatably connected to the bottom end of the first rotating bracket 3. The top end of the first rotating bracket 3 is rotatably connected to the bottom of the second rotating bracket 4. The top end of the second rotating bracket 4 is rotatably connected to the bottom surface of the support panel 5. A self-cleaning heat dissipation device 12 is fixedly installed at the center of the bottom surface of the support panel 5.

[0033] The working principle and beneficial effects of the above technical solution are as follows: When the user uses the support frame, the first rotating bracket 3 and the second rotating bracket 4 are rotated to adjust the usage angle of the support panel 5. At the same time, a self-cleaning heat dissipation device 12 is set up. When the support frame supports the laptop, it can adjust the working angle of the laptop, which is more in line with the ergonomic angle. Meanwhile, the self-cleaning heat dissipation device 12 can also dissipate heat from the laptop and clean the heat dissipation device at the same time. It ensures the normal operation of the laptop while meeting the ergonomic requirements. Example 2:

[0034] Based on the above embodiment 1, as follows Figure 1 As shown, an adjustment device is fixedly installed inside the first rotating bracket 3. The input end of the adjustment device is fixedly connected to the adjustment button 7, which is fixedly installed on the bottom side of the support panel 5.

[0035] The working principle and beneficial effects of the above technical solution are as follows: By adjusting the adjustment device through the adjustment button 7, the angle between the first rotating bracket 3 and the fixed bracket 2, and between the first rotating bracket 3 and the second rotating bracket 4 can be controlled, thereby adjusting the usage angle of the support panel 5, saving manpower and adjustment time, and making it easier for users to use the support frame. Example 3:

[0036] Based on Example 1 or 2, such as Figure 1 As shown, anti-slip pads 8 are fixedly installed around the surface of the support panel 5, and a clamping plate 6 is fixedly installed on the long side of the support panel 5 away from the fixed bracket 2.

[0037] The working principle and beneficial effects of the above technical solution are as follows: the anti-slip pad 8 can increase the friction between the laptop and the support panel 5, preventing the laptop from sliding on the surface of the support panel 5; the clamping plate 6 abuts against the side of the laptop, which can also prevent the laptop from sliding off the surface of the support panel 5, enhancing the protection of the laptop and preventing accidental damage to the laptop. Example 4:

[0038] Based on any one of Examples 1-3, such as Figure 1-2 As shown, the bottom surface of the chassis 1 is made of silicone material, and the chassis 1 is connected to the mounting surface 9 by a reinforcing device 10. The reinforcing device 10 includes an L-shaped mounting plate 101. The top end of the long rod of the L-shaped mounting plate 101 is fixedly connected to the end of the lower surface of the chassis 1 away from the mounting table 9. The center of the short rod of the L-shaped mounting plate 101 has a first threaded hole. A threaded post 102 is provided in the first threaded hole. The threaded post 102 is threadedly connected to the first threaded hole. An upper plate 103 is fixedly provided at the top end of the threaded post 102, and a lower plate 105 is fixedly provided at the bottom end of the threaded post 102. A screw block 104 is sleeved on the side wall of the threaded post 102. The center of the screw block 104 has a second threaded hole, which cooperates with the threaded post 102. The upper surface of the screw block 104 is shaped like a frustum, and the lower half of the first threaded hole is a frustum recess that matches the upper surface of the screw block 104.

[0039] The working principle and beneficial effects of the above technical solution are as follows: the contact surface between the chassis 1 and the mounting surface 9 is made of silicone material, which can increase the stability of the support frame. The reinforcement device 10 can strengthen the connection strength between the chassis 1 and the mounting surface, making it less likely for the chassis 1 to shift, thus ensuring the stability of the user when using the laptop. The specific implementation process is as follows: the user places the chassis 1 on the upper surface of the mounting surface 9, the L-shaped mounting plate in the chassis 1 extends into the lower part of the mounting surface 9, the user rotates the threaded column 102 upward so that the upper surface of the upper plate 103 fits against the lower surface of the mounting surface 9, and then rotates the screw block 104 so that it rotates into the truncated cone recess set in the lower half of the first threaded hole. The lower plate 105 prevents the screw block 104 from falling off when rotating downward. The reinforcement device 10 is easy to install and ensures the user's comfortable experience when using the laptop while optimizing the support effect of the support frame. Example 5:

[0040] Based on any one of Examples 1-4, such as Figure 3-4As shown, it also includes a fixing device 11, which includes two sets of supporting housings 111. The supporting housings 111 are fixedly installed on the upper surface of the supporting panel 5. The two supporting housings 111 are arranged symmetrically on the left and right. A first worm gear 119 is rotatably installed on the inner wall of the supporting housing 111 near the clamping plate 6. The first worm gear 119 passes through the outer wall of the supporting housing 111 and is fixedly connected to a rotating knob. The end of the first worm gear 119 near the clamping plate 6 meshes with a first worm wheel 118. The first worm wheel 118 is fixedly installed at the top of the rotating shaft 112. The rotating shaft 112 is rotatably installed on the bottom wall of the supporting housing 111. The end of the rotating shaft 112 away from the first worm wheel 118 is fixedly installed on the bottom wall of the supporting housing 111. A fixed connecting gear 1171 is provided. The end of the gear 1171 near the clamping plate 6 meshes with a rack 117. The rack 117 passes through the bottom side wall of the support housing 111 and is slidably connected to the side wall of the support housing 111. The end of the rack 117 away from the gear 1171 is fixedly connected to a bottom support rod 114. A bottom support rod 2 115 is provided behind the bottom support rod 114. The bottom support rod 114 is connected to the bottom support rod 2 115 through two left and right symmetrical clamping springs 116. The bottom support rod 114 and the bottom support rod 2 115 are located between the support housing 111. Both the bottom support rod 114 and the bottom support rod 2 115 are slidably connected to the surface of the chassis 1.

[0041] The working principle and beneficial effects of the above technical solution are as follows: When using the support frame, the user first places the laptop between the bottom support rod 114 and the bottom support rod 115, and clamps it by the clamping spring 116. The first worm gear 119 extends out of the outer wall of the support shell 111 and is fixedly connected to a rotating knob. When adjustment is needed, only the angle of the rotating knob needs to be adjusted. Specifically, rotating the rotating knob drives the first worm gear 119 to rotate, and the first worm gear 119 drives the first worm wheel 118 to rotate. At this time, the first worm wheel 118 drives the gear 1171 to rotate, and the gear drives the rack 117 to slide, thereby pushing the bottom support rod 114 and the bottom support rod 115 to adjust the position of the laptop on the chassis 1. The fixing device 11 can further improve the stability of the laptop. When the user uses the support frame, the laptop is not easy to move, ensuring the stability of the user's work. The user can also adjust the rotating knob to make the laptop in a suitable position in different usage situations, expanding the application range of the support frame. Moreover, it is simple to operate and highly practical. Example 6:

[0042] Based on any one of Examples 1-5, such as Figure 4-6As shown, a second threaded rod 1110 is fixedly connected to the end of the first worm gear 119 away from the clamping plate 6. The end of the second threaded rod 1110 away from the first worm gear 119 is rotatably connected to the inner wall of the clamping plate 6. The second threaded rod 1110 is threadedly rotatably connected to a rotating base 1111. The bottom surface of the rotating base 1111 is slidably connected to the bottom wall of the inner wall of the supporting shell 111. Two rotating holes are provided at the upper end of the rotating base 1111. The rotating holes are rotatably connected to the second threaded rod 1110 through threaded engagement. A limit frame 1112 is provided between the rotating holes. The side wall of the limit frame 1112 is connected to the rotating base 1111 through two sets of elastic rods. 11113 is rotatably connected. The center of the limiting frame 1112 is fixedly provided with a limiting sliding groove 11112. The limiting buckle is slidably connected to the limiting sliding groove 11112. The limiting buckle is fixedly set on the side of the upper support rod 113 near the limiting sliding groove 11112. The bent part of the upper support rod 113 extends out of the support shell 111. The upper support rod 113 is slidably connected to the support shell 111. The side of the upper support rod 113 away from the limiting buckle is rotatably connected to the top of the tripod 11111. The bottom of the tripod 11111 is fixedly set on the side wall of the rotating base 1111 away from the limiting frame 1112.

[0043] The working principle and beneficial effects of the above technical solution are as follows: When the fixing device 11 fixes the laptop computer, the first worm gear 119 drives the second threaded rod 1110 to rotate simultaneously. Through the threaded engagement, the rotating base 1111 moves along the direction of the second threaded rod 1110. At this time, the elastic rod 11113 will extend and retract, causing the upper support rod 113 to rotate on the tripod 11111. The upper support rod 113 supports the laptop computer screen. The limit buckle drives the upper support rod 113 to rotate, which allows the upper support rod 113 to rotate at a small angle with the movement of the bottom support rod 114, making the angle of the laptop computer screen more in line with ergonomic requirements, protecting the user's cervical spine, and making it easier for the user to quickly adjust the optimal usage angle. Example 7:

[0044] Based on any one of Examples 1-6, such as Figure 7 As shown, one end of the upper support rod 113 near the support housing 111 is slidably connected to the other upper support rod 1113. The other upper support rod 1113 is located outside the support housing 111. The upper support rod 113 and the other upper support rod 1113 are connected by an adjusting device 1114. The upper support rod 113 is also angle-adjustable by the adjusting device 1114, which includes:

[0045] The first threaded rod 11144 is rotatably mounted on the bottom wall of the inner wall of the upper support rod 113.

[0046] A horizontal bevel gear 11143 is fixedly mounted on the top of the first threaded rod 11144. The horizontal bevel gear 11143 meshes with a vertical bevel gear 11141. The vertical bevel gear 11141 is fixedly mounted on an adjusting rod. The adjusting rod restricts the horizontal displacement of the vertical bevel gear 11141. The adjusting rod is rotatably connected to the inner wall of the upper support rod 113.

[0047] The first adjustment button 11142, the adjustment rod extends out of the side wall of the upper support rod 113 in a direction away from the vertical bevel gear 11141 and is rotatably connected to the upper support rod 113, and the part of the adjustment rod extending out of the vertical bevel gear 11141 is fixedly connected to the first adjustment button 11142;

[0048] Sliding block 11145 is sleeved on the outer wall of the first threaded rod 11144. A threaded hole is provided in the center of the sliding block 11145 to be threadedly connected to the first threaded rod 11144.

[0049] Connecting block 11147, sliding block 11145 extends from one end away from the first threaded rod 11144, and the outer shell of upper support rod 113 is fixedly connected to connecting block 11147;

[0050] The second worm 11148 is rotatably disposed inside the connecting block 11147. One end of the second worm 11148 extends out of the connecting block 11147 away from the upper support rod 113 and is fixedly connected to the second adjustment button. The second worm 11148 is rotatably connected to the side wall of the connecting block 11147.

[0051] The second worm gear 11146 is fixedly sleeved on the drive rod. One end of the drive rod is rotatably mounted on the side wall of the connecting block 11147 near the first threaded rod 11144. The end of the drive rod away from the first threaded rod 11144 extends out of the side wall of the connecting block 11147 and is rotatably connected to the connecting block 11147. The extended end of the drive rod is fixedly connected to the second upper support rod 1113. Several rollers are rotatably mounted on the side wall of the second upper support rod 1113 near the first upper support rod 113. Screen cleaning cloths are sleeved on the side walls of the rollers.

[0052] The working principle and beneficial effects of the above technical solution are as follows: When placing a laptop, the display screen can be interlaced between the upper support rod 2 1113 and the upper support rod 1 113. When the upper support rod 1 is adjusted to a suitable position, the user rotates the first adjustment button 11142, which drives the vertical bevel gear 11141 to rotate, thereby driving the horizontal bevel gear 11143 to rotate. Subsequently, the first threaded rod 11144 rotates, and the sliding block 11145, through its threaded engagement with the first threaded rod 11144, undergoes displacement along the direction of the first threaded rod 11144, thereby driving the connecting block 11147 to move, thus bringing... The upper support rod 1113 is moved. At this time, the second adjustment button is rotated to make the second worm gear 11148 rotate. The second worm gear 11148 drives the second worm wheel 11146 to rotate. The second worm wheel 11146 drives the upper support rod 1113 to rotate through the driving rod. The angle of the upper support rod 1113 is adjusted by the second adjustment button to fit the laptop screen more closely. At this time, the screen cleaning cloth cleans the laptop screen.

[0057] The working principle and beneficial effects of the above technical solution are as follows: By installing a self-cleaning heat dissipation device 12 on the support frame, the support frame can achieve precise position adjustment while also dissipating heat. The input end of the cooling fan 126 can be electrically connected to the laptop port for operation. Specifically, when heat dissipation is needed, the input end of the cooling fan 126 is inserted into the laptop port. When cleaning the cooling fan 126 is required, rotating the cleaning button 1215 drives the third transmission rod 1214 to rotate, which in turn drives the second transmission rod 1213 to rotate via the second transmission belt 1212. This, through a fixed connection, drives the heat sink 124 to rotate. The second transmission rod 1213 drives the first transmission rod 129 to rotate via the first transmission belt 1211. At this time, the roller 1218... Rolling occurs within the roller groove 1216, causing the moving rod 1217 to move up and down. Simultaneously, the return spring 127 extends and retracts, thereby enabling the L-shaped rod 128 to move stably back and forth through the cleaning hole of the cleaning box 121. At this time, the cleaning brush 125 cleans the cooling fan 126 to prevent debris from affecting the rotation of the cooling fan 126 and thus its heat dissipation effect. With the assistance of the return spring 127, the L-shaped rod 128 can move up and down more stably. The rotation of the heat dissipation plate 124 enables the cooling fan 126 to achieve a better heat dissipation effect. While dissipating heat, the cleaning button 1215 can be used to clean the cooling fan 126 to prevent dust accumulation from affecting the rotation of the cooling fan 126, thus ensuring the stable operation of the cooling fan 126 and facilitating the normal operation of the laptop. Example 9:

[0064] The controller is installed on the side wall of the support panel 5. The controller is electrically connected to the angle sensor, pressure sensor, mass sensor, timer and alarm. The second controller controls the alarm to work based on the detection values ​​of the angle sensor, pressure sensor, mass sensor and timer.

[0065] Step 1: Calculate the actual utilization factor of the support frame based on the recorded values ​​of the angle sensor, pressure sensor, mass sensor, timer, and formula (1):

[0066] (1)

[0067] in, This refers to the actual utilization factor of the support frame. The timer records the moment when the support frame starts working. The timer records the time the support frame is working. The timer records the total usage time of the support frame. denoted as , where is the horizontal rotation angle of the support panel 5 recorded by the angle sensor, F is the pressure on the chassis 1 sensed by the pressure sensor when the user uses the support frame, m is the weight of the laptop placed on the support panel 5 sensed by the mass sensor, μ is the coefficient of friction of the upper surface of the support panel 5, and g is the acceleration due to gravity. This indicates the height of chassis mounting bracket 2. The horizontal width of the support panel 5 is represented by cos, tan, sin, and ln.

[0068] Step 2: The controller will calculate the actual usage coefficient of the laptop stand. Compared with the preset usage factor, when the actual usage factor When the usage coefficient is exceeded, the controller will activate the alarm to issue an alarm notification.

[0069] The working principle and beneficial effects of the above technical solution are as follows: When using the support frame, the actual utilization coefficient of the support frame is calculated by formula (1), and the controller uses the actual utilization coefficient of the support frame calculated by formula (1) Compared to the preset usage factor, the preset usage factor of the support frame is 1.8. When the actual usage factor... When the preset usage limit is exceeded, the controller will activate the alarm to alert the user that the laptop stand has been used for too long or is under excessive pressure. The user should promptly inspect and maintain the stand to prevent damage that could cause the laptop to fall. Additionally, if the user holds the laptop too close, the pressure on the stand will increase, and the alarm will also sound to remind the user to adjust their posture. This ensures that the user is at a suitable distance when using the stand and further prevents eye strain caused by being too close to the laptop.
