Description

Technical Field

[0002] The chassis generally includes an outer shell, a bracket, various switches and indicator lights on the panel, etc. As a part of computer accessories, the chassis mainly plays the role of placing and fixing various computer accessories, and plays a supporting and protective role. In addition, the computer chassis plays an important role in shielding electromagnetic radiation. Although it is not a very important configuration in DIY, using a chassis of poor quality can easily cause a short circuit between the motherboard and the chassis, making the computer system very unstable. In the process of using the chassis in daily life, it is generally placed in the desired position. At this time, the chassis needs to be kept stable, and when the chassis needs to be moved or transferred, it needs to be easy to move. Therefore, a mobile chassis with good stability is introduced.

If the terrain is inclined, the chassis may tilt and shift, and the placement is not stable enough. There is a risk of tipping over and being damaged during use. In addition, most of the existing chassis on the market can only be lifted and moved by manpower when people change the place of use and need to move.

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.

[0042] The bearing assembly 21 includes a same main board body 211 fixedly connected to the lower side of four leveling components 231, a cross groove 212 opened in the middle of the main board body 211 and a limiting groove 213 opened in the inner wall of the cross groove 212, and a slide plate 214 slidably connected to the middle of the limiting groove 213, a double-headed motor 215 is fixedly connected to the middle of the slide plate 214, a gear 216 is fixedly connected to the upper output end of the double-headed motor 215, and a bevel gear 217 is fixedly connected to the lower output end of the double-headed motor 215. When using this device, the device can be moved to the desired position through the moving wheel 2413 at the bottom, and then the double-headed motor 215 and its upper structure can be moved by the control rod 218, and the double-headed motor 215 moves along the limiting groove 213 through the slide plate 214 when the control rod 218 is toggled.

[0043] The leveling component 231 includes a limit frame 2319 fixedly connected to a corner of the lower side of the chassis body 1, a base 2311 fixedly connected to a corner of the upper side of the main board body 211, and two guide strips 2312 respectively fixedly connected to the upper sides of the left and right parts of the base 2311, and the upper sides of the two guide strips 2312 are slidably connected to the same sliding pad 2313, a bayonet 2317 is provided in the middle of one end of the base 2311, and a threaded rod 2315 is rotatably connected to the middle of the bayonet 2317, and a limit ring sleeve 2316 is fixedly connected to the outer periphery of one end of the threaded rod 2315 close to the bayonet 2317, and a threaded hole 2314 is provided in the middle of one end of the sliding pad 2313 close to the bayonet 2317, and the outer periphery of the threaded rod 2315 is threadedly connected to the threaded hole 231 4, one end of the threaded rod 2315 away from the sliding pad 2313 is fixedly connected with a bevel gear six 2318, the bayonet 2317 is arranged between the limiting ring sleeve 2316 and the bevel gear six 2318, the four leveling components 231 are respectively fixedly connected to the lower sides of the four corners of the chassis body 1, the side of the bevel gear one 217 away from the double-headed motor 215 is fixedly connected with the control rod 218, the four sliding pads 2313 are respectively slidably connected to the middle parts of the inner walls of the four limiting frames 2319, the two bevel gear six 2318 on the upper left side of the bearing component 21 are meshed with the bevel gear two 233 on the lower left side of the chassis body 1, and the two bevel gear six 2318 on the upper right side of the bearing component 21 are meshed with the bevel gear two 233 on the lower right side of the chassis body 1. When the table block 2414 is in contact with the placement surface, the double-headed motor 215 is moved again, so that the double-headed motor 215 moves left and right in turn, and the gear 1 216 meshes with the two gear 4s 235 in turn. When meshing, the double-headed motor 215 is started, and the driving gear 1 216 rotates, and the gear 3 234 is driven to rotate through the gear 4 235, so that the synchronous belt 1 236 starts to transmit, and then the bevel gear 2 233 is driven to rotate through the gear 2 232, and then the bevel gear 2 233 controls the two threaded rods 2315 of one of the left and right parts on the upper side of the main board body 211 through the two bevel gears 6 2318. Because the threads on the two threaded rods 2315 on the same part of the upper side of the main board body 211 are symmetrical with the center point of the bevel gear 233 as the center, the belt of the bevel gear 233 When the screw rod 2315 is rotated, the two bevel teeth 2316 2318 drive the two threaded rods 2315 to rotate respectively. Because the bayonet 2317 is between the limiting ring sleeve 2316 and the bevel tooth 2318, as the threaded rod 2315 rotates, the sliding pad 2313 can be pulled or pushed to slide on the guide bar 2312 through the threaded hole 2314. When sliding, the limiting frame 2319 can also be limited to a certain extent to prevent the sliding pad 2313 from accidentally deviating and detaching. Therefore, the sliding pad 2313 can slide on the guide bar 2312 to control the height of the chassis body 1 held up by the sliding pad 2313, and the stabilizing components 23 on the left and right sides of the main board body 211 can be controlled respectively, thereby adjusting the left and right inclinations of the device, so as to facilitate the device to maintain the left and right balance when placed.The two adjustable movable components 24 each include two movable parts 241 fixedly connected to the lower side of the main board body 211, two fixed rod frames 246 respectively fixedly connected to the lower sides of the front and rear parts of the main board body 211, and two positioning rods 243 respectively rotatably connected to the lower sides of the front and rear ends of the main board body 211, the end of the positioning rod 243 away from the main board body 211 is fixedly connected to the bevel gear three 245, the middle outer wall of the positioning rod 243 is fixedly connected to the gear five 244, the middle part of the end of the fixed rod frame 246 away from the main board body 211 is rotatably connected to the rotating rod 247, the end of the rotating rod 247 close to the bevel gear three 245 is fixedly connected to the bevel gear four 248, the end of the rotating rod 247 away from the bevel gear three 245 is fixedly connected to the bevel gear five 249, and the movable parts 241 includes a connecting plate 2411 fixedly connected to the lower side of the main body 211, a main frame 2412 rotatably connected to the lower side of the connecting plate 2411, and a moving wheel 2413 fixedly connected to the outer wall of the main frame 2412. The lower inner wall of the main frame 2412 is slidably connected to a block 2414. The upper inner wall of the main frame 2412 is rotatably connected to a gear six 2416. The lower middle part of the gear six 2416 is fixedly connected to a lead screw 2415. The outer periphery of the lead screw 2415 is threadedly connected to the middle part of the block 2414. The outer walls of the two gear six 2416 at the front of the lower part of the main body 211 and the outer walls of the two gear six 2416 at the rear of the lower part of the main body 211 are respectively connected by a synchronous belt 242. The two gears 2416 are connected to each other through a synchronous belt 243. The outer wall of 44 is respectively meshed with the middle inner wall of the two synchronous belts 242, and the control rod 218 is toggled, so that the double-headed motor 215 and its upper structure move forward and backward along the limit groove 213 in sequence, so that the bevel gear 1 217 is meshed with the two bevel gears 5 249 in sequence. When meshing, the double-headed motor 215 is started to drive the bevel gear 1 217 to rotate, and the bevel gear 5 249 drives the rotating rod 247 and the bevel gear 4 248 to rotate, and then the bevel gear 3 245 drives the positioning rod 243 and the gear 5 244 to rotate, thereby driving the synchronous belt 242 to transmit, and then the gear 6 2416 drives the screw 2415 to rotate. Due to the shape of the block 2414, it slides on the lower inner wall of the main frame 2412, and the screw 2415 rotates. The movable block 2414 can slide downward until it fits with the placement surface on which the device is placed, thereby allowing the moving wheels 2413 to leave the placement surface under the support of the block 2414, so that the device will not move through the moving wheels 2413 when placed for use, and the block 2414 fits with the placement surface, increasing the friction between the device and the placement surface, making the device more stable when placed, and improving the stability of the device. When the device needs to be moved, the block 2414 is raised, and the moving wheels 2413 contact the placement surface, and the device can be moved. The device can adjust the adjustable moving components 24 on the lower sides of the front and rear ends of the main body 211 respectively, thereby adjusting the front and rear inclination of the device, so that the device can maintain the front and rear balance when placed.The limit protection component 22 includes an upper cover plate 221 fixedly connected to the middle part of the upper side of the main board body 211 and a lower cover plate 222 fixedly connected to the middle part of the lower side of the main board body 211. A cross slot 223 is provided in the middle part of the upper side of the upper cover plate 221, and a cross slot 3 224 is provided in the middle part of the lower side of the lower cover plate 222. The upper output end of the double-headed motor 215 is arranged in the middle part of the cross slot 223, and the lower output end of the double-headed motor 215 is arranged in the middle part of the cross slot 3 224. The cross slot 223 and the cross slot 3 224 can also limit the double-headed motor 215 during its movement, and prevent the double-headed motor 215 and its upper structure from accidentally falling off from the middle part of the limit slot 213. The gear 1 216 is arranged above the upper cover plate 221. The tooth 1 217 and the control rod 218 are both arranged below the lower cover plate 222. The supporting and stabilizing mechanism 3 includes a fixed block 31 fixedly connected to the outer wall of the chassis body 1, a connecting block 32 rotatably connected to the inner wall of the fixed block 31, and an adapter block 33 rotatably connected to the end of the connecting block 32 away from the chassis body 1. The end of the fixed block 31 away from the chassis body 1 is rotatably connected to a leg 35, and the end of the adapter block 33 away from the connecting block 32 is rotatably connected to the middle part of the leg 35 close to the end of the fixed block 31. The middle part of the lower end of the adapter block 33 is rotatably connected to a spring rod 37, and the end of the spring rod 37 away from the adapter block 33 is fixedly connected to a positioning slide rod 38. The outer wall of the leg 35 is provided with two slide grooves 39, and the two slide grooves 39 are respectively provided at two separated outer walls of the leg 35. The positions of the two slide grooves 39 correspond to each other, and the two ends of the positioning slide bar 38 are slidably connected to the middle parts of the two slide grooves 39 respectively. The outer wall of the lower end of the transfer block 33 is rotatably connected with a connecting strip 34, and the end of the connecting strip 34 away from the spring rod 37 is rotatably connected to the inner wall of the lower end of the fixed block 31. The upper side of the support leg 35 is fixedly connected with a buffer plate 36, and the lower side of the end of the support leg 35 close to the fixed block 31 is provided with an anti-obstruction groove 310. When placing, the support and stabilization mechanism 3 of the outer wall of the chassis body 1 can be lowered to strengthen the support for the device, so that the device can adapt to more types of placement surfaces and be placed more firmly. When the device needs to be moved, the support and stabilization mechanism 3 can be pulled up so that the support and stabilization mechanism 3 can be turned up to the surface close to the chassis body 1, which is convenient for moving the device. During the flipping process of the supporting and stabilizing mechanism 3, the supporting legs 35 are rotated through the connecting blocks 32, the transfer blocks 33 and the connecting strips 34. During the rotation process, the positioning slide bar 38 slides in the slide groove 39 due to the flipping of the supporting legs 35. As the supporting legs 35 flip and gradually become perpendicular to the outer wall surface of the chassis body 1, the positioning slide bar 38 reaches one end of the slide groove 39 close to the fixed block 31 and stretches the spring rod 37. When the spring rod 37 is perpendicular to the outer wall of the chassis body 1, the spring rod 37 is stretched to the maximum. When the vertical point is passed, the spring rod 37 can gradually retract and relax. Therefore, when the supporting and stabilizing mechanism 3 is moved to be close to the outer wall of the chassis body 1 or supported on the ground, the supporting and stabilizing mechanism 3 can remain stable and will not shake at will. The anti-blocking groove 310 can prevent the spring rod 37 from being affected when rotating.The buffer plate 36 blocks and buffers when the supporting and stabilizing mechanism 3 is in close contact with the surface of the chassis body 1, thereby preventing the supporting and stabilizing mechanism 3 from accidentally wearing the outer wall of the chassis body 1.

[0044] Working principle: When using the device, the device can be moved to the desired position through the moving wheel 2413 at the bottom, and then the double-headed motor 215 and the upper structure thereof can be moved through the control rod 218. The double-headed motor 215 moves along the limit slot 213 through the slide plate 214 when the control rod 218 is turned, and the cross slot 223 and the cross slot 3 224 can also limit the double-headed motor 215 during its movement, and prevent the double-headed motor 215 and the upper structure thereof from accidentally falling off from the middle of the limit slot 213. The control rod 218 is turned to make the double-headed motor 215 and the upper structure thereof move forward and backward in sequence along the limit slot 213, so that the bevel tooth 1 217 is meshed with the two bevel teeth 5 249 in sequence. When meshing, the double-headed motor 215 is started to drive the bevel teeth 249 to engage with the bevel teeth 249. The first 217 rotates, and the bevel gear five 249 drives the rotating rod 247 and the bevel gear four 248 to rotate, and then the bevel gear three 245 drives the positioning rod 243 and the gear five 244 to rotate, thereby driving the synchronous belt two 242 to transmit, and then the gear six 2416 drives the lead screw 2415 to rotate. Due to the shape of the block 2414, it slides on the lower inner wall of the main frame 2412. Under the rotation of the lead screw 2415, the block 2414 can slide downward until it fits with the placement surface where the device is placed, thereby making the moving wheel 2413 leave the placement surface under the support of the block 2414, so that the device will not be moved by the moving wheel 2413 when placed for use, and the block 2414 fits with the placement surface, increasing the friction between the device and the placement surface, so that The device is more stable when placed, which improves the stability of the device. When the device needs to be moved, the table block 2414 is raised, and the moving wheel 2413 contacts the placement surface to move the device. The device can adjust the adjustable moving components 24 on the lower sides of the front and rear ends of the main body 211 respectively, thereby adjusting the front and rear inclination of the device, so that the device can maintain the front and rear balance when placed. When placing the device, after the table block 2414 contacts the placement surface, the double-headed motor 215 is moved again, so that the double-headed motor 215 moves left and right in turn, and the gear one 216 meshes with the two gear fours 235 in turn. When meshing, the double-headed motor 215 is started, and the gear one 216 is driven to rotate, and the gear three 234 is driven to rotate through the gear four 235, so that the synchronous belt one 236 The transmission starts, and then the gear 232 drives the bevel gear 233 to rotate. Then the bevel gear 233 controls the two threaded rods 2315 on the left and right sides of the upper side of the main body 211 through the two bevel gears 6 2318 at the same time. Because the threads on the two threaded rods 2315 on the same part of the upper side of the main body 211 are symmetrical with the center point of the bevel gear 233, the two bevel gears 6 2318 drive the two threaded rods 2315 to rotate respectively under the drive of the bevel gear 233. Because the bayonet 2317 is between the limiting ring sleeve 2316 and the bevel gear 6 2318, as the threaded rod 2315 rotates, the sliding pad 2313 can be pulled or pushed to slide on the guide bar 2312 through the threaded hole 2314. When sliding, the limiting frame 2319 can also be limited to a certain position.The sliding pad 2313 is prevented from accidentally shifting and disengaging, so that the sliding pad 2313 can slide on the guide bar 2312 to control the height of the sliding pad 2313 to hold up the chassis body 1, and the stabilizing components 23 on the left and right parts of the upper side of the main board 211 can be controlled respectively, so that the left and right inclinations of the device can be adjusted, so that the device can maintain the balance on the left and right sides when it is placed. Through the cooperation of the stabilizing component 23 and the adjustable movable component 24, the device can be leveled according to the terrain when it is placed, so that the device can be kept vertical and fit the placement surface. When placing, the supporting and stabilizing mechanism 3 on the outer wall of the chassis body 1 can be lowered to strengthen the support for the device, so that the device can adapt to more types of placement surfaces and be placed more firmly. When the device needs to be moved, the supporting and stabilizing mechanism 3 can be pulled up so that the supporting and stabilizing mechanism 3 can be flipped up to fit the surface of the chassis body 1, which is convenient for the movement of the device and the supporting and stabilizing mechanism. During the flipping process of the fixed mechanism 3, the legs 35 rotate through the connecting block 32, the adapter block 33 and the connecting strip 34. During the rotation process, the positioning slide bar 38 slides in the slide groove 39 due to the flipping of the legs 35. As the legs 35 flip and gradually become perpendicular to the outer wall surface of the chassis body 1, the positioning slide bar 38 reaches the end of the slide groove 39 close to the fixed block 31 and stretches the spring rod 37. When the spring rod 37 is perpendicular to the outer wall of the chassis body 1, the spring rod 37 is stretched to the maximum. When the vertical point is passed, the spring rod 37 can gradually retract and relax. Therefore, when the supporting and stabilizing mechanism 3 is moved to be close to the outer wall of the chassis body 1 or supported on the ground, the supporting and stabilizing mechanism 3 can remain stable and will not shake at will. The anti-blocking groove 310 can prevent the spring rod 37 from being affected when rotating. The buffer plate 36 blocks and buffers when the supporting and stabilizing mechanism 3 is close to the surface of the chassis body 1 to prevent the supporting and stabilizing mechanism 3 from accidentally wearing the outer wall of the chassis body 1.
