Technical Field

[0001] This utility model relates to the field of hard disk technology, and in particular to a chassis and a hard disk recorder. Background Technology

[0002] Existing hard disk recorders typically secure the hard disk to the chassis base using screws or other fasteners, and also secure the chassis cover and chassis base using screws or other fasteners.

[0003] When a hard drive needs to be repaired or replaced, the top cover of the computer case must be removed before the hard drive can be installed or removed. In addition, multiple screws and other fasteners need to be removed or tightened during the installation and removal process. The installation and removal steps are cumbersome and it is easy to accidentally touch other electronic components such as the motherboard inside the computer case, making the operation inconvenient. Utility Model Content

[0004] Therefore, it is necessary to provide a chassis and hard disk recorder to address the above problems, so as to facilitate the installation and removal of hard disks.

[0005] This utility model provides a chassis, including: a chassis body having a mounting cavity and an opening communicating with the mounting cavity; a bracket for mounting a hard drive, the bracket being able to be inserted into the mounting cavity through the opening; and a cover detachably covering the opening, and the chassis body being magnetically connected.

[0006] In the aforementioned chassis, when removing the hard drive, first remove the cover from the chassis, then pull the bracket and hard drive together out of the mounting cavity through the opening, and finally detach the hard drive from the bracket. When installing the hard drive, first install the hard drive onto the bracket, then insert the bracket and hard drive together into the mounting cavity through the opening, and finally connect the cover to the chassis using magnetic attraction, so that the cover closes the opening and prevents the bracket and hard drive from coming out of the mounting cavity. During the process of removing and installing the cover, as well as inserting or removing the bracket and hard drive into or out of the mounting cavity, there is no need to remove or install multiple screws or other fasteners. The process is simple and convenient, and it will not accidentally touch other electronic components inside the mounting cavity, thus achieving rapid hard drive removal and installation, improving hard drive maintenance efficiency, and reducing maintenance costs.

[0007] In one embodiment, the cover includes a first side and a second side arranged opposite to each other, the first side being fixed to the box body by magnetic attraction, and the second side being detachably snapped onto the box body.

[0008] With this configuration, the second side engages with the box to position the lid and prevent the lid from shifting relative to the box, thus affecting the lid's ability to close the opening. The first side is fixed to the box via magnetic attraction to ensure the stability and reliability of the connection between the lid and the box.

[0009] In one embodiment, the cover further includes a protrusion and a snap-fit ​​portion disposed on the second side. The box body is provided with a first snap-fit ​​and a second snap-fit.

[0010] With this design, the protrusion is positioned within the first latch to hold the cover in place, and the latch engages with the second latch to improve the stability and reliability of the connection between the second side of the cover and the box.

[0011] In one embodiment, the cover has a force-applying part on the side facing away from the mounting cavity, a guide protrusion on the side facing the mounting cavity, and a mating part that can slide and engage with the guide protrusion along the interval direction between the first side and the second side.

[0012] With this configuration, a force is applied to the force-applying part toward the first side, causing the entire cover to slide toward the first side. The guide protrusion engages with the mating part, allowing the first side of the cover to detach from the box during the sliding process, making it easier for the user to disassemble the cover.

[0013] In one embodiment, the bracket includes a frame and a fixing member. The frame includes a bottom wall and two side walls disposed opposite to each other on both sides of the bottom wall. The fixing member is detachably disposed on the side walls and is used to connect and cooperate with the socket of the hard drive.

[0014] This design, through the connection between the fastener and the hard drive's socket, ensures the stability and reliability of the connection between the hard drive and the bracket. Furthermore, the connection structure between the hard drive and the bracket is simple, making it easy for users to install and remove the hard drive.

[0015] In one embodiment, the frame is a sheet metal part, the side wall is provided with mounting holes, the mounting holes have inter-connected insertion holes and fixing holes, the fastener can be inserted from the insertion hole and slid to the fixing hole to fix the fastener to the side wall.

[0016] This design makes the assembly and disassembly of the fasteners and the frame simple and convenient, and the contact area between the fasteners and the side wall is large, thus ensuring the stability and reliability of the connection between the fasteners and the side wall. When installing a hard drive, the bending and deformation capabilities of the sheet metal parts can be used to insert the fasteners on the side wall into the hard drive's socket.

[0017] In one embodiment, each sidewall is provided with two mounting holes, which are arranged at intervals along the insertion direction of the bracket and are symmetrical to each other, and the fasteners are arranged in a one-to-one correspondence with the mounting holes.

[0018] With this design, even if the fastener is affected by the rigidity of the hard drive, the fastener will not slide from the fixing hole to the insertion hole, thus ensuring the stability and reliability of the connection between the fastener and the side wall.

[0019] In one embodiment, the bracket includes a frame and an elastic handle, the elastic handle being disposed at one end of the frame facing the opening, one of the elastic handle and the housing having a limiting part, and the other having a limiting groove capable of engaging with the limiting part; and / or, the bracket includes a frame and a first buffer member, the first buffer member being disposed at one end of the frame away from the opening; and / or, the bracket has a first mounting hole for fixing the hard drive to the hard drive with fasteners.

[0020] With this design, after the bracket is inserted into place, the limiting part can engage with the limiting slot to fix the bracket to the cabinet and prevent the bracket from shifting in the mounting cavity; the first buffer can play a buffering role when the bracket and hard drive are inserted into the mounting cavity; meeting the needs of special scenarios with high vibration requirements.

[0021] In one embodiment, the enclosure includes a detachably connected base and a top cover. The top cover includes a U-shaped top plate and two first side plates connected to each other. The first side plates cover the outer side of the base. The top cover is slidable relative to the base to open / close the enclosure. And / or, the enclosure also includes a panel that is detachably snapped onto the enclosure. And / or, the enclosure includes a slide rail disposed in the mounting cavity. The slide rail and the inner wall of the mounting cavity are provided to form a groove communicating with the opening.

[0022] This design integrates the top and two sides of the enclosure into a single unit, reducing visible seams and enhancing the overall aesthetics of the chassis. The panel is easy to install and remove from the enclosure, facilitating user maintenance. The sliding grooves limit the sliding direction and installation position of the bracket within the mounting cavity.

[0043] Existing hard disk recorders typically secure the hard drive to the chassis base using screws and other fasteners, and the chassis cover and base are also secured with screws and other fasteners. When repairing or replacing the hard drive, the chassis cover must be removed first to access the hard drive. This process involves removing or tightening multiple screws and other fasteners, making the process cumbersome and increasing the risk of accidentally touching other electronic components such as the motherboard inside the chassis, resulting in inconvenient operation.

[0044] To solve the above problems, such as Figures 1 to 12 As shown, this utility model first provides a chassis to facilitate the installation and removal of hard drives.

[0045] like Figures 1 to 3 As shown, specifically, the chassis includes a housing 1, a bracket 2, and a cover 3, wherein: the housing 1 has a mounting cavity 11 and an opening 12 communicating with the mounting cavity 11; the bracket 2 is used to install a hard disk 6, and the bracket 2 can be inserted into the mounting cavity 11 through the opening 12; the cover 3 is detachably covered on the opening 12 and is connected to the housing 1 by magnetic attraction.

[0046] In the chassis provided by this utility model embodiment, when disassembling the hard drive 6, the cover 3 is first removed from the chassis 1, then the bracket 2 and the hard drive 6 are pulled out of the mounting cavity 11 through the opening 12, and finally the hard drive 6 is removed from the bracket 2. When installing the hard drive 6, the hard drive 6 is first installed on the bracket 2, then the bracket 2 and the hard drive 6 are inserted into the mounting cavity 11 through the opening 12, and finally the cover 3 is magnetically connected to the chassis 1, so that the cover 3 closes the opening 12, preventing the bracket 2 and the hard drive 6 from coming out of the mounting cavity 11 from the opening 12. In this way, during the process of disassembling and assembling the cover 3 and inserting or pulling the bracket 2 and the hard drive 6 into or out of the mounting cavity 11, it is not necessary to disassemble or assemble multiple screws or other fasteners. The disassembly and assembly process is simple and convenient, and it will not accidentally touch other electronic components inside the mounting cavity 11, so as to achieve quick disassembly and assembly of the hard drive 6, improve the maintenance efficiency of the hard drive 6, and reduce maintenance costs.

[0047] like Figure 1 As shown, the enclosure 1 and the cover 3 can be made of the same material, such as sheet metal or plastic. In the assembled state, the outer surface of the cover 3 is preferably flush with the outer surface of the enclosure 1. That is, from the overall perspective, the outer surface of the cover 3 and the outer surface of the enclosure 1 form a surface similar to one surface. Here, the influence caused by assembly error or assembly gap is ignored, thereby improving the overall aesthetics of the enclosure.

[0048] like Figure 8 As shown, the chassis also includes a magnetic component 5. When both the chassis 1 and the cover 3 are made of sheet metal or other metal materials, the magnetic component 5 is installed on one of the chassis 1 and the cover 3 to attract the other of the chassis 1 and the cover 3. Alternatively, magnetic components 5 that can attract each other can be installed on both the chassis 1 and the cover 3. Taking the magnetic component 5 installed on the chassis 1 as an example, the magnetic component 5 can include a magnet 51 and a Mylar component 52. The magnet 51 is fixed to the side of the chassis 1 facing the cover 3 by means of adhesive, screws, etc. The Mylar component 52 is attached to the surface of the magnet 51 facing the cover 3. Thus, the magnetic force of the magnetic component 5 can be adjusted by changing the thickness of the Mylar component 52, or a magnet 51 with a suitable magnetic force can be directly selected. When one of the housing 1 and the cover 3 is made of sheet metal or other metal material, and the other is made of plastic or other non-metal material, the magnetic component 5 is provided on the plastic part so that the sheet metal part can be attracted by the magnetic component 5; alternatively, magnetic components 5 that can attract each other can be provided on both the sheet metal part and the plastic part. When both the housing 1 and the cover 3 are made of plastic or other non-metal material, magnetic components 5 that can attract each other can be provided on both the housing 1 and the cover 3.

[0049] like Figure 3As shown, a motherboard 7 can also be installed inside the mounting cavity 11. When the bracket 2 and the hard drive 6 are inserted into the mounting cavity 11 through the opening 12, the interface of the hard drive 6 mates with the interface of the motherboard 7, thus electrically connecting the hard drive 6 and the motherboard 7. The motherboard 7 can be fixed to the enclosure 1 with screws or other fasteners to ensure the stability and reliability of the connection between the motherboard 7 and the enclosure 1.

[0050] like Figures 7 to 8 As shown, the cover 3 includes a first side 31 and a second side 32 arranged opposite to each other. The first side 31 is fixed to the box 1 by magnetic attraction, and the second side 32 is detachably snapped to the box 1. When installing the cover 3, the second side 32 is first snapped to the box 1 to position the cover 3 and prevent the cover 3 from shifting relative to the box 1, which would affect the effect of the cover 3 closing the opening 12. Then, the first side 31 is fixed to the box 1 by magnetic attraction to ensure the stability and reliability of the connection between the cover 3 and the box 1.

[0051] like Figure 4 and Figure 8 As shown, the cover 3 also includes a protrusion 33 and a latching part 34 disposed on the second side 32. The housing 1 is provided with a first latch 13 and a second latch 14. In the assembled state, the protrusion 33 is latched in the first latch 13, and the latching part 34 is engaged with the second latch 14. The protrusion 33 is latched in the first latch 13 to position the cover 3 and prevent the cover 3 from shifting relative to the housing 1, which would affect the effect of the cover 3 closing the opening 12. The engagement of the latching part 34 with the second latch 14 can improve the stability and reliability of the connection between the second side 32 of the cover 3 and the housing 1. Specifically, the protrusion 33 can be bent from the second side 32, and the latching part 34 can be bent from the end of the protrusion 33 away from the second side 32, so that the cover 3 is integrally formed, which facilitates the processing of the cover 3 and also ensures the overall strength of the cover 3.

[0052] like Figure 5 As shown, the cover 3 has a force-applying part 35 on the side facing away from the mounting cavity 11, and a guide protrusion 36 on the side facing the mounting cavity 11. The housing 1 has a mating part 15 that can slide and engage with the guide protrusion 36 along the interval direction of the first side 31 and the second side 32. When disassembling the cover 3, a force can be applied to the force-applying part 35 toward the first side 31, causing the cover 3 to slide toward the first side 31 as a whole. The protrusion 33 and the latching part 34 disengage from the first latch 13 and the second latch 14, respectively. At the same time, the guide protrusion 36 engages with the mating part 15, so that the first side 31 of the cover 3 disengages from the housing 1 during the sliding process, that is, the first side 31 of the cover 3 protrudes from the outer surface of the housing 1, so as to facilitate the user to disassemble the cover 3. Specifically, the mating part 15 can be a recessed structure that can fit with the guide protrusion 36, or a protruding structure that can abut against the guide protrusion 36.

[0053] like Figure 4 As shown, in order to prevent the cover 3 from sliding toward the first side 31, and during the process of the first side 31 separating from the box 1, the protrusion 33 and the buckle 34 interfere with each other with the box 1, the first latch 13 and the second latch 14 are both provided with a clearance space extending toward the side of the mounting cavity 11, so as to ensure the normal assembly and disassembly of the cover 3.

[0054] like Figure 10 As shown, the bracket 2 includes a frame 21 and a fixing member 22. The frame 21 includes a bottom wall 211 and two side walls 212 opposite to each other on both sides of the bottom wall 211. The fixing member 22 is detachably disposed on the side wall 212 and is used to connect and cooperate with the socket 61 of the hard drive 6. In the assembled state, the hard drive 6 is placed in the space enclosed by the bottom wall 211 and the two side walls 212, and is connected and cooperated with the socket 61 of the hard drive 6 by the fixing member 22 to ensure the stability and reliability of the connection between the hard drive 6 and the bracket 2. Furthermore, the connection structure between the hard drive 6 and the bracket 2 is simple, making it convenient for users to install and remove the hard drive 6.

[0055] like Figures 10 to 11 As shown, in one embodiment, the frame 21 is a sheet metal part, and the side wall 212 is provided with mounting holes 213. The mounting holes 213 have interconnected insertion holes 2131 and fixing holes 2132. The fastener 22 can be inserted from the insertion hole 2131 and slid to the fixing hole 2132 to fix the fastener 22 to the side wall 212. When installing the fastener 22, first insert the fastener 22 into the insertion hole 2131, and then slide the fastener 22 to the fixing hole 2132; when removing the fastener 22, first slide the fastener 22 from the fixing hole 2132 to the insertion hole 2131, and then remove the fastener 22 from the insertion hole 2131. Thus, the assembly and disassembly of the fastener 22 and the frame 21 are simple and convenient, and the contact area between the fastener 22 and the side wall 212 is large, thereby ensuring the stability and reliability of the connection between the fastener 22 and the side wall 212, and preventing the fastener 22 from accidentally coming out of the mounting hole 213 when disassembling or assembling the hard drive 6. The fastener 22 can be made of metal to ensure the strength of the fastener 22 and prevent breakage when disassembling or assembling the hard drive 6. Specifically, the fastener 22 includes a fixing part 221 and a fixing post 222 protruding from the fixing part 221. The outer periphery of the fixing part 221 is also provided with a fixing groove 223. The fixing part 221 engages with the edge of the fixing hole 2132 through the fixing groove 223, and the fixing post 222 is used to engage with the insertion hole 61 of the hard drive 6. Furthermore, the inner wall of the connection between the insertion hole 2131 and the fixing hole 2132 can have a certain degree of elasticity to facilitate the fastener 221 to engage or disengage from the fixing hole 2132.

[0056] When installing the hard drive 6, first insert the fixing piece 22 on one side wall 212 into the socket 61 of the hard drive 6. Then, using the bending deformation capability of the sheet metal, bend the frame 21 and insert the fixing piece 22 on the other side wall 212 into the socket 61 of the hard drive 6 to achieve a fixed connection between the hard drive 6 and the bracket 2. Similarly, when removing the hard drive 6, first remove the fixing piece 22 on one side wall 212 from the socket 61 of the hard drive 6. Then, using the bending deformation capability of the sheet metal, bend the frame 21 and remove the fixing piece 22 on the other side wall 212 from the socket 61 of the hard drive 6. The frame 21 can be designed to be thinner than the bottom wall 211 and have grooves cut into it to reduce the strength of the bottom wall 211, increase its bending deformation capability, facilitate the installation and removal of the hard drive 6, and simultaneously increase the strength of the side wall 212, improving the stability and reliability of the connection between the side wall 212, the fixing piece 22, and the hard drive 6.

[0057] like Figures 10 to 11 As shown, each sidewall 212 has two mounting holes 213, which are spaced apart and symmetrically arranged along the insertion direction of the bracket 2. The fastener 22 is arranged in a one-to-one correspondence with each mounting hole 213. That is, the insertion holes 2131 of the two mounting holes 213 on each sidewall 212 are close to each other, while the fixing holes 2132 are far apart; or the fixing holes 2132 of the two mounting holes 213 on each sidewall 212 are close to each other, while the insertion holes 2131 are far apart. Thus, in the assembled state, even if the fastener 22 is affected by the rigidity of the hard drive 6, for example, if the hard drive 6 slides relative to the frame 21, the fastener 22 will not slide from the fixing hole 2132 to the insertion hole 2131, thereby further ensuring the stability and reliability of the connection between the fastener 22 and the sidewall 212.

[0058] Of course, in other embodiments, the hard disk 6 can be placed on the frame 21 first, and then the fixing member 22 can be installed on the side wall 212, so that the fixing member 22 and the socket 61 of the hard disk 6 can be plugged in and cooperated. As long as the hard disk 6 and the bracket 2 can be detachably fixed, this utility model embodiment does not make specific limitations here.

[0059] like Figure 8 and Figure 10As shown, the bracket 2 also includes an elastic handle 23, which is located at the end of the frame 21 facing the opening 12. One of the elastic handle 23 and the housing 1 has a limiting part 231, and the other has a limiting groove 16 that can engage with the limiting part 231. When installing the bracket 2, it is inserted into the mounting cavity 11 through the opening 12. After insertion, the limiting part 231 engages with the limiting groove 16, fixing the bracket 2 to the housing 1 and preventing displacement within the mounting cavity 11, thereby improving the stability and reliability of the connection between the bracket 2 and the housing 1. When disassembling the bracket 2, the elastic handle 23 is first deformed to disengage the limiting part 231 from the limiting groove 16, and then the bracket 2 is pulled out of the mounting cavity 11. Thus, the assembly and disassembly process of the bracket 2 is simple and convenient for user operation. There can be two elastic handles 23. The limiting part 231 and the limiting groove 16 are arranged one-to-one with the elastic handle 23. The two elastic handles 23 are arranged opposite each other on both sides of the end of the frame 21 facing the opening 12. When disassembling the bracket 2, press the elastic handles 23 on both sides inward so that the limiting parts 231 on both sides are dislodged from the limiting groove 16.

[0060] like Figures 10 to 11 As shown, the bracket 2 also includes a first buffer 24, which is disposed at the end of the bracket 21 away from the opening 12. The first buffer 24 can be an elastic arm, a silicone component, or other structures with elastic deformation capabilities, so as to provide a buffering effect when the bracket 2 and the hard disk 6 are inserted into the mounting cavity 11, preventing the bracket 2, the hard disk 6, and other electronic components such as the motherboard 7 in the mounting cavity 11 from being damaged by impact.

[0061] like Figures 10 to 11 As shown, the bracket 2 also includes a second buffer 26, which is disposed on the inner side of the side wall 212. The second buffer 26 can be an elastic arm, a silicone part, or other structures with elastic deformation capabilities. In the assembled state, the side of the second buffer 26 away from the side wall 212 contacts the hard disk 6, thereby providing shock absorption for the hard disk 6 and protecting it.

[0062] like Figures 10 to 11 As shown, the bracket 2 also includes a third buffer 27, which is located on the side of the side wall 212 away from the bottom wall 211. The third buffer 27 can be an elastic arm, a silicone part, or other structures with elastic deformation capabilities, thereby providing a buffering effect between the bracket 2 and the inner wall of the mounting cavity 11, facilitating the adjustment of the gap between the bracket 2 and the inner wall of the mounting cavity 11.

[0063] like Figure 12As shown, the frame 21 of the bracket 2 is also provided with a first mounting hole 25, which is used to fix the hard drive 6 to the bracket 2 using fasteners. When there are special usage scenarios with high vibration requirements, the hard drive 6 can be fixed to the frame 21 at the first mounting hole 25 with fasteners to further improve the stability and reliability of the connection between the bracket 2 and the hard drive 6. Furthermore, the size of the frame 21 is generally matched with the size of the hard drive 6. Taking the size of the frame 21 matching a 3.5-inch hard drive 6 as an example, in order to make the frame 21 suitable for other sizes of hard drives 6, such as 2.5-inch hard drives 6, a first mounting hole 25 matching a 2.5-inch hard drive 6 can be machined on the frame 21 to expand the applicability of the bracket 2. Alternatively, the 2.5-inch hard drive 6 can be installed on other compatible mounting brackets first, and then the hard drive 6 and the mounting bracket can be connected to the frame 21 as a whole using fasteners 22.

[0064] like Figure 7 and Figure 9 As shown, the enclosure 1 includes a detachably connected base 17 and a top cover 18. The top cover 18 includes a U-shaped top plate 181 and two first side plates 182 connected to each other. The first side plates 182 cover the outside of the base 17. The top cover 18 can slide relative to the base 17 to open or close the enclosure 1. In the assembled state, the U-shaped top cover 18 makes the top surface and two sides of the enclosure 1 form a whole, reducing the appearance seams and thus improving the overall aesthetics of the enclosure. Specifically, the base 17 includes a U-shaped bottom plate 171 and two second side plates 172 connected to each other. The first side plates 182 cover the outside of the second side plates 172. An opening 12 is provided on the second side plate 172, and a clearance hole 183 is provided on the first side plate 182 at the position corresponding to the opening 12. Ventilation holes can be provided on both the enclosure 1 and the cover 3 as needed. One of the base 17 and the top cover 18 is provided with a first buckle 184, and the other is provided with a first slot 174 that can engage with the first buckle 184. After the top cover 18 slides into place, the first buckle 184 engages with the first slot 174. At the same time, the top cover 18 is also provided with a second mounting hole 185. The top cover 18 and the base 17 can also be fixed at the second mounting hole 185 with screws or other fasteners to ensure the stability and reliability of the connection between the base 17 and the top cover 18. The base 17 is also provided with a groove 173 extending along the sliding direction of the top cover 18 to improve the stability of the top cover 18 when sliding relative to the base 17.

[0065] like Figure 1 , Figure 7 and Figure 9As shown, the chassis also includes a panel 4, which is detachably snapped onto the chassis 1. Specifically, the panel 4 includes a front panel 41 and a back panel 42, which are positioned opposite each other at both ends of the base 17 along the sliding direction of the upper cover 18. The upper cover 18 can be slidably installed and removed from the side of the base 17 where the back panel 42 is located. The back panel 42 has a clearance position 421 corresponding to the first buckle 184. The front panel 41 has functional components such as indicator lights and buttons. One of the front panel 41 and the base 17 has a second buckle 411 and a spring buckle 412, and the other has a second slot 175 that can engage with the second buckle 411 and the spring buckle 412. The engagement of the second buckle 411 and the second slot 175 ensures the stability and reliability of the connection between the front panel 41 and the base 17, and the engagement of the spring buckle 412 and the second slot 175 facilitates the installation and removal of the front panel 41. One of the front panel 41 and the base 17 is provided with a positioning post 413, and the other is provided with a positioning hole 176 that can be inserted and engaged with the positioning post 413, so as to facilitate the user's positioning of the front panel 41. The back panel 42 is provided with an interface for electrical connection with the main board 7. One of the back panel 42 and the base 17 is provided with a third buckle 422, and the other is provided with a third slot 177 that can be engaged with the third buckle 422. The back panel 42 can be made of sheet metal, and the bending deformation capability of the sheet metal can be used to assemble and disassemble the back panel 42 and the base 17. In this way, the assembly and disassembly process of the panel 4 and the housing 1 is simple and convenient, so as to facilitate the user's maintenance of the panel 4.

[0066] like Figures 6 to 8 As shown, the housing 1 includes a slide rail 19 disposed within the mounting cavity 11. The slide rail 19 and the inner wall of the mounting cavity 11 form a groove 191 communicating with the opening 12. The groove 191 can restrict the sliding direction and installation position of the bracket 2 within the mounting cavity 11, ensuring that when the bracket 2 slides into place, the interface of the hard drive 6 can accurately mate with the interface of the motherboard 7, while further improving the stability and reliability of the bracket 2 within the mounting cavity 11. Specifically, the slide rail 19 can be fixed to the base 17 by screws or other fasteners to ensure the stability and reliability of the connection between the slide rail 19 and the base 17. The first bayonet 13, the second bayonet 14, the limiting groove 16, and the magnetic suction member 5 can all be disposed on the slide rail 19.
