Description

Technical Field

[0001] The utility model relates to the technical field of chassis structures, and more specifically, to the technical field of an openable chassis structure. Background Art

[0002] With the development of equipment such as military servers and computers, more and more modules are inserted into the chassis, and the power consumption is increasing. To ensure the heat dissipation of the product, a module-up insertion scheme is usually adopted in the chassis. For the module-up chassis, a cover plate is usually provided at the upper position of the chassis shell and is connected to the shell itself by screws.

[0003] When maintaining the internal modules of the chassis, all the screws of the cover plate need to be removed, and then the modules are plugged and unplugged. Conventional military equipment requires the maintenance time to be no more than 30 minutes, and even some users require the maintenance time of the equipment to be no more than 5 minutes. However, this connection method requires tools to disassemble the screws, the operation is cumbersome, and the cover plate, screws are separated from the chassis, which is likely to cause some safety hazards, such as loss of parts, and scratches on the components caused by accidental dropping of screws. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a chassis, which solves the problems of cumbersome disassembly of the cover plate and easy dropping of parts in the prior art, and improves the convenience and safety of maintenance.

[0005] A chassis, including a chassis shell and a cover plate, characterized in that a flipping assembly is provided between the cover plate and the chassis shell, the cover plate realizes opening and closing relative to the chassis shell through the flipping assembly, a pressing lock is further provided on the cover plate, and a lock catch matched with the pressing lock is provided on the chassis shell.

[0006] When it is necessary to open the cover plate for maintaining the inside of the chassis, only need to apply pressure to the position where the pressing lock is located, the lock catch pops out, and the cover plate realizes flipping relative to the chassis shell through the flipping assembly, which is convenient for the staff to maintain the inside of the chassis. When the maintenance is completed and the cover plate needs to be closed, only need to close the cover plate and then apply pressure to the position where the pressing lock is located, so as to realize the locking of the cover plate. The pressing lock is a commonly used mechanical connection element in the prior art, such as the connection between a memory card and an electronic device, such as a ballpoint pen, and such as an emergency stop switch on an automatic logistics vehicle. It fixes and connects two components by pressing one component into the hole of another component and using the friction or shape fit between the inner hole and the outer component. This connection method does not require threads, so it has the advantages of simple installation, compact structure, corrosion resistance, and anti-loosening. Common flipping assemblies include the form of a combination of a rotating shaft and a rotating seat and a hinge connection to realize the relative rotation of the cover plate and the chassis shell.

[0007] This type of chassis realizes the rapid opening, closing and locking of the cover by providing the flip assembly and the push locker. Compared with the screw connection method, the opening and closing of the cover of this type of chassis does not require the use of tools, and the operation is convenient, which can shorten the maintenance time of the chassis. In addition, the cover is always connected to the chassis shell, does not detach from the chassis shell, and has no other parts that fall off, which can effectively avoid the safety hazard of parts loss or parts falling causing the loss of other parts, and improve the safety of maintenance.

[0008] As a preferred embodiment of the present invention, a limit assembly is provided on the cover plate, and the limit assembly includes a connecting piece and a connecting groove, the connecting groove is located on the chassis shell and contains a groove wall and a cavity for accommodating the connecting piece, the connecting piece includes a connecting plate portion and a resistance portion, the connecting plate portion is connected to the cover plate, and the resistance portion resists against the groove wall, thereby achieving the limitation of the maximum opening and closing angle of the cover plate.

[0009] The connecting piece is arranged on the cover plate, and the connecting groove is arranged on the chassis shell, so as to ensure that the cover plate can be opened and closed smoothly. When the cover plate is rotated to a certain angle, the interference part on the connecting piece and the groove wall of the connecting groove are interfered with, thereby effectively limiting the maximum opening and closing angle of the cover plate, ensuring that the cover plate cannot continue to rotate after opening to a certain angle, and effectively preventing the cover plate from hitting the chassis shell due to inertia or gravity during the opening and closing process, thereby affecting the stability of the internal parts of the chassis. This design improves safety and stability while achieving rapid opening and closing.

[0010] As a preferred embodiment of the present invention, the forming size of the connecting plate portion is larger than that of the abutting portion.

[0011] The connecting plate is connected to the cover plate and needs to bear a certain connection stress, so its size cannot be too thin or too narrow, otherwise it is easy to deform or break. The smaller size of the abutment portion can occupy a smaller space in the chassis during the opening and closing process, thereby not occupying the space position of the module inside the chassis.

[0012] As a preferred embodiment of the utility model, the connecting plate portion includes a main plate and a transverse insert plate connected to the main plate, the extension direction of the main plate is perpendicular to the extension direction of the transverse insert plate, and the cover plate is provided with a card slot that cooperates with the transverse insert plate.

[0013] Due to the design of the transverse insert, the connecting plate can be easily inserted into or removed from the card slot on the cover, making the installation and removal of the connecting plate easier and quicker. The extension direction of the main plate is perpendicular to the extension direction of the transverse insert. This design can ensure a stable connection while making the connecting plate more space-saving and not occupying too much space.

[0014] Preferably, the present utility model is provided with two limiting components, which are respectively located on both sides of the cover plate.

[0015] The two limiting components can provide more balanced support and limitation, making the cover plate more stable during the opening and closing processes, reducing the shaking or accidental closing caused by unstable center of gravity. And being located at the edge position of the cover plate can not occupy the space of the internal modules of the chassis, and is also more conducive to the maintenance of the modules by the staff.

[0016] Preferably, the flipping component includes a rotating shaft, and a first shaft seat and a second shaft seat respectively sleeved on both ends of the rotating shaft. The first shaft seat is connected to the chassis shell, and the second shaft seat is connected to the cover plate.

[0017] Through the connection of the rotating shaft and the two shaft seats, a stable flipping action can be achieved. And the structure of the flipping component is simple, and during long-term use, the wear is small, thereby improving the service life of the device.

[0018] Preferably, there are more than two pressing lockers.

[0019] Multiple pressing lockers can provide a more uniform pressure distribution, which helps to prevent the fixed object from moving or shaking, thereby enhancing the overall stability.

[0020] Preferably, a shielding strip for preventing electromagnetic leakage is provided between the cover plate and the chassis shell.

[0021] The shielding strip can be made of conductive rubber commonly used in the prior art. The conductive rubber has good elasticity and electrical conductivity, can effectively shield electromagnetic waves and prevent dust from entering the interior of the chassis, and has good sealing performance. In addition, the elastic material can also play a certain shock-absorbing effect, which can meet the requirements of the chassis for compatible electromagnetic and vibration environments.

[0022] Preferably, a first cross beam, a second cross beam and an upper insertion slot are provided inside the chassis shell. Both ends of the first cross beam and the second cross beam are connected to the chassis shell. The upper insertion slot is located between the first cross beam and the second cross beam. The flipping component is arranged on the first cross beam, and the lock catch is arranged on the second cross beam.

[0023] The settings of the first cross beam and the second cross beam provide force application points for the flipping assembly and the pressing lock, and at the same time provide additional support for the chassis housing, preventing the deformation of the chassis housing during long-term use, ensuring that the entire structure is more solid and stable, and capable of withstanding greater external pressure or impact. In addition, the design of the upper insertion slot can effectively utilize the vertical space, facilitating the staff to insert and remove the module for maintenance. And being located between the first cross beam and the second cross beam can ensure that the module will not be restricted by the first cross beam and the second cross beam during the insertion and removal process.

[0024] As a preference of the present utility model, a handle is provided on the chassis housing.

[0025] The handle is provided on the chassis housing instead of on the cover plate, which can effectively reduce the accidental opening of the cover plate caused by misoperation. Significantly improve the protection performance of the chassis, prevent unnecessary accidental touches from triggering the opening action of the cover plate, and further ensure the safety and reliability of the device.

[0026] To sum up, the present utility model has the following beneficial effects:

[0027] 1. The opening and closing of the cover plate of this kind of chassis do not require tools, are convenient to operate, and can shorten the maintenance time of the chassis.

[0028] 2. The cover plate is always connected to the chassis housing, without detaching from the chassis housing, nor are there other parts falling off, which can effectively avoid the safety hazards of part loss or part dropping causing damage to other components, and improve the safety of maintenance.

[0029] 3. The limiting component effectively limits the maximum opening and closing angle of the cover plate, ensuring that the cover plate cannot continue to rotate after opening to a certain angle, effectively avoiding the cover plate hitting the chassis housing due to the influence of inertia or gravity during the opening and closing process, thereby affecting the stability of the internal components of the chassis.

[0030] 4. The design of the main piece and the horizontal insertion piece can save space for the connection plate part while ensuring stable connection, and will not occupy too much space. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] like Figure 1 As shown, the flip assembly 3 is arranged on the cross beam 9, and the cover plate 2 is opened and closed relative to the chassis housing 1 through the flip assembly 3. Figure 2 As shown, the flip assembly 3 specifically includes a rotating shaft 301 and an axle seat 1 302 and an axle seat 2 303 respectively sleeved with the two ends of the rotating shaft 301, the axle seat 1 302 is connected to the cross beam 1 9, and the axle seat 2 303 is connected to the cover plate 2. Through the connection between the rotating shaft 301 and the two axle seats, a stable flipping action can be achieved. In addition, the flip assembly 3 has a simple structure and is less worn during long-term use, thereby increasing the service life of the device. In addition to the combination of the rotating shaft and the axle seat, flipping can also be achieved through a hinge connection commonly used in the prior art.

[0037] The chassis shell is provided with an upper insertion slot 8, and the cross beam 1 9 and the upper insertion slot 8 are located between the cross beam 1 9 and the cross beam 2 10. The setting of the cross beam 1 9 and the cross beam 2 10 provides a force point for the flip assembly 3 and the press lock 4, and also provides additional support for the chassis shell 1 to prevent the chassis shell 1 from being deformed during long-term use, ensuring that the entire structure is more solid and stable, and can withstand greater external pressure or impact. In addition, the design of the upper insertion slot 8 can effectively utilize the vertical space, making it convenient for the staff to plug and unplug the module for maintenance, and it is located between the cross beam 1 9 and the cross beam 2 10, which can ensure that the module will not be restricted by the cross beam 1 9 and the cross beam 2 10 during the plug-in and unplug process.

[0038] The cover plate 2 is also provided with a push locker 4, and the cross beam 10 is provided with a lock that matches the push locker 4. The push locker 4 is a commonly used mechanical connection element in the prior art, such as the connection between a memory card and an electronic device, a ballpoint pen, and an emergency stop switch on an automatic logistics vehicle. It fixes and connects the two components by pressing one component into the hole of another component and utilizing the friction or shape fit between the inner hole and the outer component. This connection method does not require threads, so it has the advantages of easy installation, compact structure, corrosion resistance, and anti-loosening. When it is necessary to open the cover plate 2 for maintenance inside the chassis, it is only necessary to apply pressure to the position where the push locker 4 is located, and the locker pops up. The cover plate 2 is flipped relative to the chassis shell 1 through the flip assembly 3, which is convenient for the staff to maintain the inside of the chassis. When the maintenance is completed and the cover plate 2 needs to be closed, it is only necessary to close the cover plate 2 and apply pressure to the position where the push locker 4 is located, so as to achieve the locking of the cover plate 2.

[0039] Compared with the screw connection method, the cover plate 2 of this type of chassis can be opened and closed without the use of tools, and the operation is convenient, which can shorten the chassis maintenance time. Moreover, the cover plate 2 is always connected to the chassis shell 1, and does not separate from the chassis shell 1, and there are no other parts that fall off, which can effectively avoid the safety hazard of parts loss or parts falling causing the loss of other parts, and improve the safety of maintenance.

[0040] As a preferred embodiment of the present invention, the cover plate 2 is provided with a limit assembly 5, which includes a connector 501 and a connector groove 502. The connector groove 502 is located on the chassis housing 1 and includes a groove wall and a cavity for accommodating the connector 501. The connector 501 includes a connecting plate portion 5011 and an abutting portion 5012. Figure 3 , 4 As shown, when the cover is closed, the connector 501 is located in the connector groove 502. When the cover 2 is rotated to a certain angle, the interference portion 5012 on the connector 501 interferes with the groove wall of the connector groove 502, thereby effectively limiting the maximum opening and closing angle of the cover 2, ensuring that the cover 2 cannot continue to rotate after opening to a certain angle, and effectively preventing the cover 2 from hitting the chassis housing 1 due to inertia or gravity during the opening and closing process, thereby affecting the stability of the internal components of the chassis. This design improves safety and stability while achieving rapid opening and closing.

[0041] In addition, the forming size of the connecting plate portion 5011 is larger than that of the abutting portion 5012. This is because the connecting plate portion 5011 is connected to the cover plate 2 and needs to bear a certain connection stress. Therefore, its specification size cannot be too thin or too narrow, otherwise it is prone to deformation or breakage. The smaller forming size of the abutting portion 5012 can occupy a smaller space in the chassis during the opening and closing process, thus not occupying the space position of the internal modules in the chassis. Moreover, the connecting plate portion 5011 includes a main piece and a transverse insertion piece connected to the main piece. The extending direction of the main piece is perpendicular to the extending direction of the transverse insertion piece. The cover plate 2 is provided with a card slot that cooperates with the transverse insertion piece. Due to the design of the transverse insertion piece, the connecting plate portion can be conveniently inserted into or removed from the card slot on the cover plate 2, making the installation and disassembly process of the connecting plate portion more simple and fast. The extending direction of the main piece is perpendicular to the extending direction of the transverse insertion piece. This design can save more space in the connecting plate portion while ensuring stable connection and will not occupy too much space.

[0042] Preferably, in this embodiment, there are two limiting components 5, which are respectively located on both sides of the cover plate 2. The two limiting components 5 can provide more balanced support and limitation, making the cover plate 2 more stable during the opening and closing processes, reducing the shaking or accidental closing caused by unstable center of gravity. And being located at the edge position of the cover plate 2 can not occupy the space position of the internal modules in the chassis and is also more conducive to the staff to maintain the modules.

[0043] Preferably, in this embodiment, there are more than two pressing lockers 4. The multiple pressing lockers 4 can provide a more uniform pressure distribution, which helps to prevent the fixed object from moving or shaking, thereby enhancing the overall stability.

[0044] Preferably, in this embodiment, a handle 6 is provided on the chassis shell 1. The handle 6 is provided on the chassis shell 1 instead of on the cover plate 2, which can effectively reduce the accidental opening of the cover plate 2 caused by misoperation. It significantly improves the protection performance of the chassis, prevents unnecessary accidental touches from triggering the opening action of the cover plate 2, and further ensures the safety and reliability of the device.

[0045] Preferably, in this embodiment, a shielding strip 7 for preventing electromagnetic leakage is provided between the cover plate 2 and the chassis shell 1. The shielding strip 7 can be made of conductive rubber commonly used in the prior art. The conductive rubber has good elasticity and conductivity, can effectively shield electromagnetic waves and prevent dust from entering the interior of the chassis, and has good sealing performance. In addition, the elastic material can also play a certain shock-absorbing effect, which can meet the requirements of the chassis for compatible electromagnetic and vibration environments.

[0046] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
