Description

Technical Field

[0001] This invention relates to the field of rack technology, and in particular to an adjustable rack for wall-mounted cabinets. Background Technology

[0002] Wall-mounted server racks, as a space-saving equipment installation solution, are widely used in corridors, narrow wall areas, small computer rooms, and industrial sites. They are mainly used to house light to medium-sized equipment such as network switches, small servers, power modules, and security equipment, while also taking into account installation flexibility and electrical safety.

[0003] Existing racks can use guide rails to move mounting racks, allowing servers to be quickly installed on them. After server installation, to prevent the internal temperature of the rack from becoming too high, multiple mounting racks are arranged vertically inside the rack. When the server is used in a cold region, the hot air inside the rack is quickly expelled, lowering the internal temperature. This not only alters the performance of electronic components due to low temperatures but also accelerates the aging of cables and connecting parts. Therefore, we propose an adjustable rack for wall-mounted racks. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides an adjustable rack for wall-mounted cabinets.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] An adjustable rack for wall-mounted server racks includes a rack body, a heat dissipation cover fixed to the top of the rack body for heat dissipation, a rear baffle fixed between the rack body and the heat dissipation cover, a first mounting bracket and a second mounting bracket for installing servers inside the rack body, and a guide rail for sliding the first and second mounting brackets inside the rack body, a power mechanism for reciprocating movement of the first mounting bracket between the rack body and the first mounting bracket, and a switching mechanism for reciprocating movement of the second mounting bracket between the first and second mounting brackets, which can drive the second mounting bracket to reciprocate when the first mounting bracket reciprocates;

[0007] The power mechanism includes a fixing plate that is fixed to the inner wall of the cabinet body, a dual-axis motor that is fixed to the side of the fixing plate, and a transmission mechanism that is provided between the dual-axis motor and the first mounting bracket.

[0008] The switching mechanism includes a positioning sleeve disposed on the opposite side of the first mounting frame and the second mounting frame. An extension rod is disposed between the positioning sleeve and the first mounting frame and the second mounting frame, and an exhaust mechanism is disposed outside the extension rod.

[0009] As a preferred embodiment of the present invention, the transmission mechanism includes a transmission rod fixed on the output shaft of a dual-axis motor. A transmission plate is provided at the end of the transmission rod away from the dual-axis motor. A connecting rod is fixed between the transmission plate and the first mounting frame. A limiting rod for limiting the transmission plate is also fixed on the side of the fixed plate near the first mounting frame. The transmission rod is L-shaped. The output shaft of the dual-axis motor drives the transmission rod to rotate. The limiting rod limits the transmission plate, causing the transmission rod to drive the transmission plate to move laterally back and forth. The transmission plate drives the connecting rod to move laterally back and forth. The connecting rod drives the first mounting frame to cooperate with the guide rail, causing the first mounting frame to move back and forth.

[0010] As a preferred embodiment of the present invention, the transmission plate has a slot on the side near the dual-axis motor, and a spiral boss is fixed inside the slot. A slide rod is provided at the end of the transmission rod away from the dual-axis motor. A spring column for resetting the slide rod is fixed between the slide rod and the transmission rod. The end of the slide rod away from the transmission rod is inserted into the slot, and the end of the slide rod inserted into the slot contacts the boss. When the transmission rod rotates, the transmission rod drives the slide rod to rotate counterclockwise, and the slide rod moves along the inside of the slot. The boss limits the slide rod, so that the slide rod can only rotate counterclockwise, preventing the trajectory of the slide rod from deviating when it moves inside the slot.

[0011] As a preferred embodiment of the present invention, wedge blocks are fixed at the top and bottom of the transmission plate, and a wedge groove adapted to the wedge blocks is provided in the middle of the limiting rod. When the transmission rod drives the sliding rod to move along the inside of the groove, the transmission plate is moved by the sliding rod cooperating with the groove. The transmission plate drives the wedge blocks to move, and the wedge blocks cooperate with the limiting rod to make the transmission plate move horizontally back and forth. The transmission plate drives the first mounting frame to move horizontally back and forth through the connecting rod, thereby facilitating the installation of the server inside the first mounting frame.

[0012] As a preferred embodiment of the present invention, the ventilation mechanism includes a locking rod fixed to the outer wall of the positioning sleeve, a positioning block fixed in the middle of the locking rod, and an exhaust fan for promoting airflow inside the cabinet body provided outside the positioning block. The ends of the two extension rods away from the positioning sleeve are respectively fixed to guide rails fixed outside the first mounting frame and the second mounting frame. When the first mounting frame moves horizontally, the first mounting frame drives the guide rail to move horizontally, the guide rail drives the extension rod fixed outside it to move horizontally, and the extension rod fixed outside the guide rail drives the positioning sleeve to rotate vertically around its central axis, so that the positioning sleeve drives the guide rail fixed outside the second mounting frame to move horizontally, thereby driving the second mounting frame to move horizontally through the guide rail fixed outside the second mounting frame, so that the first mounting frame and the second mounting frame move alternately.

[0013] As a preferred embodiment of the present invention, two mounting plates are fixed to the outside of the two extension rods. Two racks are fixed to one side of the two mounting plates facing each other. A gear that meshes with the two racks is provided on the side of the positioning block away from the positioning sleeve. The rotating shaft of the exhaust fan is fixed to the side of the gear away from the positioning sleeve. When the extension rods rotate, the extension rods drive the mounting plates to rotate around the axis of the gears. At the same time, the extension rods drive the mounting plates to move obliquely to the side away from the gears, so that the distance between the two mounting plates increases. The mounting plates drive the exhaust fan to rotate around the axis of the gears. The mounting plates can also drive the racks to move obliquely, so that the racks change from a vertical state to an inclined state. The racks drive the gears that mesh with them to rotate, and the gears drive the exhaust fan to rotate.

[0014] As a preferred embodiment of the present invention, each of the two racks is fixed with a support frame on one side facing each other. The support frame is arrow-shaped and the two support frames are respectively located above and below the gear. When the mounting plate drives the rack to reset, the mounting plate drives the rack from an inclined state to a vertical state, and the support frame limits the rack.

[0015] As a preferred embodiment of the present invention, two insert rods are also fixed to the outside of the second mounting bracket. A wind baffle is screwed to one end of each insert rod away from the second mounting bracket. A reinforcing rod is fixed between the two insert rods. A diagonal rod is fixed between the reinforcing rod and the wind baffle. A threaded portion is provided at one end of the insert rod near the wind baffle. A nut that matches the threaded portion is provided on the side of the wind baffle near the second mounting bracket. The insert rod is fixed to the second mounting bracket by a screw. An air inlet is provided in the middle of the rear baffle. The wind baffle is located on the side of the air inlet. When the second mounting bracket moves horizontally, the second mounting bracket drives the insert rod to move horizontally back and forth. The insert rod drives the wind baffle to move horizontally back and forth, causing the wind baffle to separate from the rear baffle. At the same time, the horizontal movement of the wind baffle increases the airflow velocity inside the cabinet body and can also allow air from outside the cabinet body to enter the interior of the cabinet body through the rear baffle.

[0016] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0017] 1. This invention, through the cooperation of a power mechanism, a first mounting frame, a dual-axis motor, a transmission rod, a transmission plate, and a connecting rod, drives the first mounting frame to move laterally and reciprocally, so that the relative position of the first mounting frame and the second mounting frame is dynamically adjusted. This allows the hot air inside the cabinet to gradually circulate through the gap formed between the two mounting frames and then slowly exit through the heat dissipation cover. This avoids the rapid exhaust of hot air in cold regions, which would cause the internal temperature of the cabinet to drop too low. This reduces the risk of the performance of electronic components being affected by low temperatures and slows down the aging of cables and connecting parts.

[0018] 2. The present invention achieves the alternating movement of the first mounting frame and the second mounting frame through the cooperation of the switching mechanism, positioning sleeve, extension rod, first mounting frame and second mounting frame and other structures. The alternating movement mode can further slow down the loss of hot air in the cabinet body, so that the hot air stays in the cabinet for a longer time, thereby more accurately maintaining the stability of the internal temperature of the cabinet.

[0019] 3. Through the cooperation of structures such as extension rods, mounting plates, exhaust fans, racks and gears, the first mounting frame and the second mounting frame drive the exhaust fan to rotate synchronously when they move alternately. This not only retains the advantage of alternating movement of the mounting frames to reduce the loss of hot air and avoid low temperature problems, but also accelerates the air flow inside the cabinet through the exhaust fan, effectively preventing the temperature inside the cabinet from becoming too high due to the accumulation of hot air, thus achieving bidirectional balance regulation of the temperature inside the cabinet.

[0020] 4. The present invention guides the slide rod to rotate counterclockwise along the inside of the slot through the cooperation of the transmission plate, transmission rod, slot and slide rod, and uses the limiting effect of the slot on the slide rod to accurately constrain its movement trajectory, ensuring that the slide rod moves according to the trajectory of the slot, thereby increasing the stability of the device during operation.

[0021] 5. This invention further enhances the airflow velocity inside the cabinet through the combination of structures such as plug rods, baffles, and second mounting brackets. This not only complements the active cooling of the exhaust fan, but also avoids local air stagnation by dynamically adjusting the airflow path, thereby comprehensively improving the heat dissipation efficiency inside the cabinet.

[0022] 6. This invention increases the support force of the wind deflector by combining structures such as insert rods, wind deflectors, reinforcing rods, and diagonal rods, preventing damage caused by excessive air pressure during reciprocating movement of the wind deflector.

[0038] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0039] Example: The present invention provides, as follows Figure 1The wall-mounted adjustable rack shown includes a rack body 1, a heat dissipation cover 2 fixed on the top of the rack body 1 for heat dissipation, a rear baffle 5 fixed between the rack body 1 and the heat dissipation cover 2, a first mounting bracket 4 and a second mounting bracket 6 for installing servers are provided inside the rack body 1, and a guide rail 3 is also provided inside the rack body 1 to drive the first mounting bracket 4 and the second mounting bracket 6 to slide.

[0040] As can be seen from the above, when in use, the first mounting bracket 4 and the second mounting bracket 6 are pulled and moved to the outside of the rack body 1 via the guide rail 3. The server to be installed is then placed inside the first mounting bracket 4 and the second mounting bracket 6, and the server is installed inside the first mounting bracket 4 and the second mounting bracket 6 with bolts. The heat dissipation cover 2 can also exhaust the hot air inside the rack body 1.

[0041] refer to Figure 2 , Figure 3 and Figure 4 As shown, a power mechanism 7 is provided between the cabinet body 1 and the first mounting frame 4 to drive the first mounting frame 4 to reciprocate.

[0042] refer to Figure 5 and Figure 6 As shown, the power mechanism 7 includes a fixing plate 701 that is fixed to the inner wall of the cabinet body 1. A dual-axis motor 702 is fixed to the side of the fixing plate 701. A transmission mechanism is provided between the dual-axis motor 702 and the first mounting bracket 4.

[0043] refer to Figure 7 , Figure 8 and Figure 9 As shown, the transmission mechanism includes a transmission rod 703 fixed on the output shaft of the dual-axis motor 702. A transmission plate 704 is provided at the end of the transmission rod 703 away from the dual-axis motor 702. A connecting rod 705 is fixed between the transmission plate 704 and the first mounting frame 4. A limiting rod 708 for limiting the transmission plate 704 is also fixed on the side of the fixing plate 701 near the first mounting frame 4. The transmission rod 703 is L-shaped. The power mechanism 7 can drive the first mounting frame 4 to reciprocate. The output shaft of the dual-axis motor 702 drives the transmission rod 703 to rotate. The limiting rod 708 limits the transmission plate 704, so that the transmission rod 703 drives the transmission plate 704 to reciprocate laterally. The transmission plate 704 drives the connecting rod 705 to reciprocate laterally. The connecting rod 705 drives the first mounting frame 4 to cooperate with the guide rail 3, so that the first mounting frame 4 reciprocates.

[0044] refer to Figure 7 , Figure 8 and Figure 9As shown, a slot 706 is provided on the side of the transmission plate 704 near the dual-axis motor 702. A spiral boss is fixed inside the slot 706. A slide rod 710 is provided at the end of the transmission rod 703 away from the dual-axis motor 702. A spring column 709 for resetting the slide rod 710 is fixed between the slide rod 710 and the transmission rod 703. The end of the slide rod 710 away from the transmission rod 703 is inserted into the slot 706. The end of the slide rod 710 inserted into the slot 706 contacts the boss. When the transmission rod 703 rotates, the transmission rod 703 drives the slide rod 710 to rotate counterclockwise. The slide rod 710 moves along the inside of the slot 706. The boss limits the slide rod 710, so that the slide rod 710 can only rotate counterclockwise, preventing the slide rod 710 from deviating from its trajectory when moving inside the slot 706.

[0045] refer to Figure 7 , Figure 8 and Figure 9 As shown, wedge blocks 707 are fixed at the top and bottom of the transmission plate 704. A wedge groove adapted to the wedge block 707 is opened in the middle of the limiting rod 708. When the transmission rod 703 drives the slide rod 710 to move along the inside of the slot 706, the transmission plate 704 is moved by the cooperation of the slide rod 710 and the slot 706. The transmission plate 704 drives the wedge block 707 to move. The wedge block 707 cooperates with the limiting rod 708 to make the transmission plate 704 move horizontally back and forth. The transmission plate 704 drives the first mounting frame 4 to move horizontally back and forth through the connecting rod 705, so that people can install the server inside the first mounting frame 4.

[0046] The output shaft of the dual-axis motor 702 drives the transmission rod 703 to rotate. The transmission rod 703 drives the slide rod 710 to rotate counterclockwise through the elastic column 709, causing the slide rod 710 to move along the inside of the slot 706. The slide rod 710 cooperates with the slot 706 to drive the transmission plate 704 to move. The transmission plate 704 drives the wedge block 707 to move. The wedge block 707 cooperates with the limit rod 708 to make the transmission plate 704 move horizontally back and forth. The transmission plate 704 drives the first mounting frame 4 to move horizontally back and forth through the connecting rod 705, changing the relative position of the first mounting frame 4 and the second mounting frame 6. The first mounting frame 4 and the second mounting frame 6 are combined to form a step shape. The first mounting frame 4 and the second mounting frame 6 are used to block the rising hot air, so that the hot air is discharged after passing through the gap between the first mounting frame 4 and the second mounting frame 6.

[0047] refer to Figure 10 and Figure 11As shown, a switching mechanism 8 is also provided between the first mounting bracket 4 and the second mounting bracket 6 to drive the second mounting bracket 6 to reciprocate. The switching mechanism 8 includes a positioning sleeve 801 located on the opposite side of the first mounting bracket 4 and the second mounting bracket 6. An extension rod 802 is provided between the positioning sleeve 801 and both the first mounting bracket 4 and the second mounting bracket 6. The first mounting bracket 4 and the second mounting bracket 6 are rotatably connected to the two extension rods 802 respectively. The opposite side of the two extension rods 802 is movably connected to the positioning sleeve 801, and the ends of the two extension rods 802 away from the first mounting bracket 4 and the second mounting bracket 6 are inserted into the interior of the positioning sleeve 801. A ventilation mechanism is also provided outside the extension rods 802. (See reference) Figure 11 , Figure 12 and Figure 13 As shown, the ventilation mechanism includes a locking rod 808 fixed to the outer wall of the positioning sleeve 801, a positioning block 809 fixed in the middle of the locking rod 808, and an exhaust fan 804 provided on the outside of the positioning block 809 to promote the airflow inside the cabinet body 1.

[0048] The switching mechanism 8 can drive the second mounting frame 6 to reciprocate when the first mounting frame 4 reciprocates. The ends of the two extension rods 802 away from the positioning sleeve 801 are respectively fixed to the guide rails 3 fixed outside the first mounting frame 4 and the second mounting frame 6. When the first mounting frame 4 moves horizontally, the first mounting frame 4 drives the guide rail 3 to move horizontally. The guide rail 3 drives the extension rods 802 fixed outside it to move horizontally. The extension rods 802 fixed outside the guide rail 3 drive the positioning sleeve 801 to rotate vertically around its central axis, so that the positioning sleeve 801 drives the guide rail 3 fixed outside the second mounting frame 6 to move horizontally. Thus, the guide rail 3 fixed outside the second mounting frame 6 drives the second mounting frame 6 to move horizontally, so that the first mounting frame 4 and the second mounting frame 6 reciprocate alternately.

[0049] refer to Figure 11 , Figure 12 and Figure 13As shown, two mounting plates 803 are fixed to the outside of the two extension rods 802. Two racks 805 are fixed to the opposite side of the two mounting plates 803. A gear 806 that meshes with the two racks 805 is provided on the side of the positioning block 809 away from the positioning sleeve 801. The rotating shaft of the exhaust fan 804 is fixed to the side of the gear 806 away from the positioning sleeve 801. When the extension rods 802 rotate, the extension rods 802 drive the mounting plates 803 to rotate around the axis of the gear 806. At the same time, the extension rods 802 drive the mounting plates 803 to move obliquely away from the gear 806, so that the distance between the two mounting plates 803 increases. The mounting plates 803 drive the exhaust fan 804 to rotate around the axis of the gear 806. The mounting plates 803 can also drive the racks 805 to move obliquely, so that the racks 805 change from a vertical state to an inclined state. The racks 805 drive the gears 806 that mesh with them to rotate, and the gears 806 drive the exhaust fan 804 to rotate.

[0050] refer to Figure 11 , Figure 12 and Figure 13 As shown, each of the two racks 805 has a support frame 807 fixed on one side facing each other. The support frame 807 is arrow-shaped, and the two support frames 807 are respectively located above and below the gear 806. When the mounting plate 803 drives the rack 805 to reset, the mounting plate 803 drives the rack 805 from the inclined state to the vertical state, and the support frame 807 limits the rack 805.

[0051] refer to Figure 14 As shown, two insert rods 810 are also fixed to the outside of the second mounting bracket 6. A wind deflector 811 is screwed to the end of each insert rod 810 away from the second mounting bracket 6. A reinforcing rod 812 is fixed between the two insert rods 810. A diagonal rod 813 is fixed between the reinforcing rod 812 and the wind deflector 811. A threaded portion is provided at the end of the insert rod 810 near the wind deflector 811. A nut matching the threaded portion is provided on the side of the wind deflector 811 near the second mounting bracket 6. The insert rod 810 is connected to the second mounting bracket 6 via a threaded rod. The second mounting bracket 6 is fixed in place. An air inlet is provided in the middle of the rear baffle 5. The baffle plate 811 is set on the side of the air inlet. When the second mounting bracket 6 moves horizontally, the second mounting bracket 6 drives the insertion rod 810 to move horizontally back and forth. The insertion rod 810 drives the baffle plate 811 to move horizontally back and forth, so that the baffle plate 811 is separated from the rear baffle 5. At the same time, the horizontal movement of the baffle plate 811 increases the air flow rate inside the cabinet body 1, and can also allow the air outside the cabinet body 1 to enter the interior of the cabinet body 1 through the rear baffle 5.

[0052] When the first mounting bracket 4 moves, it drives the guide rail 3 to move horizontally. The guide rail 3 drives the extension rod 802 fixed to its outside to move horizontally. The extension rod 802 and the positioning sleeve 801 fixed to the outside of the guide rail 3 rotate vertically around their central axis, causing the positioning sleeve 801 to drive another extension rod 802 to rotate. The other extension rod 802 drives the guide rail 3 fixed to the outside of the second mounting bracket 6 to move horizontally, causing the guide rail 3 to drive the second mounting bracket 6 to move horizontally. The extension rod 802 can also drive... The movable mounting plate 803 rotates around the axis of the gear 806. At the same time, the extension rod 802 drives the mounting plate 803 to move obliquely away from the gear 806, increasing the distance between the two mounting plates 803. The mounting plate 803 drives the exhaust fan 804 to rotate around the axis of the gear 806. The mounting plate 803 can also drive the rack 805 to move obliquely, changing the rack 805 from a vertical state to an inclined state. The rack 805 drives the gear 806 meshing with it to rotate, and the gear 806 drives the exhaust fan 804 to rotate.

[0053] Working principle:

[0054] When used in cold winter, the output shaft of the dual-axis motor 702 drives the transmission rod 703 to rotate. The transmission rod 703 drives the slide rod 710 to rotate counterclockwise through the elastic column 709, causing the slide rod 710 to move along the inside of the slot 706. The slide rod 710 and the slot 706 cooperate to drive the transmission plate 704 to move. The transmission plate 704 drives the wedge block 707 to move. The wedge block 707 cooperates with the limit rod 708 to make the transmission plate 704 move horizontally back and forth. The transmission plate 704 drives the first mounting frame 4 to move horizontally back and forth through the connecting rod 705, so that the relative position of the first mounting frame 4 and the second mounting frame 6 changes.

[0055] When the first mounting bracket 4 moves, it causes the guide rail 3 mounted on its exterior to move horizontally. The guide rail 3, in turn, causes the extension rod 802 fixed to its exterior to move horizontally. The extension rod 802 and the positioning sleeve 801, fixed to the exterior of the guide rail 3, rotate vertically around their central axis. This causes the positioning sleeve 801 to rotate another extension rod 802, which in turn causes the guide rail 3 fixed to the exterior of the second mounting bracket 6 to move horizontally. This, in turn, causes the guide rail 3 to move the second mounting bracket 6 horizontally. The extension rod 802 can also drive the mounting plate 803 to rotate around the axis of the gear 806. At the same time, the extension rod 802 drives the mounting plate 803 to move obliquely away from the gear 806, increasing the distance between the two mounting plates 803. The mounting plate 803 drives the exhaust fan 804 to rotate around the axis of the gear 806. The mounting plate 803 can also drive the rack 805 to move obliquely, changing the rack 805 from a vertical state to an inclined state. The rack 805 drives the gear 806 meshing with it to rotate, and the gear 806 drives the exhaust fan 804 to rotate.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
