[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.
[0058] Combination Figure 1b , Figure 2 and Figure 5 The heat dissipation system provided in the embodiment of the present application includes: a chassis 40, a fan assembly 10 and a plurality of functional components 20; the chassis 40 has an air inlet T1 and an air outlet T2 which are relatively arranged along a first direction (referenced to the straight line direction where the y-axis is located), and these functional components 20 are arranged in the chassis 40 in sequence and adjacently along a second direction (referenced to the straight line direction where the x-axis is located). For the convenience of distinction, two adjacent functional components 20 are defined as a first functional component 20 and a second functional component 20 respectively. It should be understood that the definition is relative. When any one of the functional components 20 is selected as the first functional component 20, the adjacent functional components 20 can be called the second functional component 20. Therefore, the second functional component 20 has the same structure as the first functional component 20.
[0059] The first functional components 20 mentioned above may include an installation box 21 and a switching network board 22 located in the installation box 21. These switching network boards 22 may be perpendicular to the x-axis, arranged in parallel and spaced apart in sequence. A group of service boards 30 are provided between the air inlet T1 and the switching network board 22. These service boards 30 are arranged in sequence and spaced apart. Each service board 30 may be parallel to the xoy plane. Each switching network board 22 may be electrically connected to each service board 30 in the group of service boards 30 at the same time, thereby realizing an orthogonal architecture of the switching network board 22 and the service board 30. Related components 31 (see Figures 2 to 5 It should be understood that the service board 30 may be replaced by another type of board (referred to as the first board), and the switching network board 22 may be replaced by another type of board (referred to as the second board), as long as the orthogonal architecture of the first board and the second board can be realized.
[0060] The fan assembly 10 is located at the air outlet T2, and includes a plurality of fans 11 arranged along a second direction (referenced to the straight line direction where the x-axis is located), the second direction (referenced to the straight line direction where the x-axis is located) being perpendicular to the first direction (referenced to the straight line direction where the y-axis is located), and the fans 11 are used to drive the airflow P from the air inlet T1 to the air outlet T2. The panel (front panel 211) of the first functional component 20 facing the fan assembly 10 is provided with a damper 24, so as to control whether the first functional component 20 is ventilated in the first direction (referenced to the straight line direction where the y-axis is located) by opening and closing the damper 24 according to the state of the fan 11. For the opening state of the damper 24, please refer to Figure 6 For example, please refer to the closed state of the air valve 24 Figure 7 For example, Figure 3 and Figure 4 In the embodiment, some fans 11 are not in place, some fans 11 are in place and fail, and the air valves 24 corresponding to the fans 11 in place and fail and the fans 11 not in place are in a closed state. The first functional component 20 has a ventilation channel W (reference x-axis direction) that runs through the first functional component 20 along the second direction (reference x-axis direction). Figures 6 to 8 ), when the fan 11 fails in place or is replaced, the airflow P of the first functional component 20 can be transferred to the fans 11 on both sides through the ventilation duct W to prevent the first functional component 20 from being windless. The flow path of the airflow P can refer to Figures 2 to 4 , Figure 2 and Figure 4 In the case of a fault, some fans 11 are not in place. Figure 3 In the embodiment, some fans 11 fail in place, and the airflow P of the first functional component 20 corresponding to the fans 11 that fail in place and the fans 11 that are not in place can be transferred to the fans 11 on both sides through the ventilation duct W for discharge (the dotted line part represents that the airflow P is transferred). At least one opening 25 of the ventilation duct W is provided with a flap 23, Figure 1b and Figure 2 In the embodiment, the flap 23 is only provided at the opening 25 on one side of the ventilation duct W to prevent the flaps 23 on both sides of the same empty slot S from interfering with each other. However, the movement trajectory of the flap 23 can also be designed to prevent interference between the flaps 23. Thus, the flaps 23 are provided at the openings 25 at both ends of the ventilation duct W. The flap 23 has a first position (refer to Figure 2 or Figure 6 Position ②) and the second station (reference Figure 2 or Figure 6 When the flap 23 is in the first position (reference Figure 2 or Figure 6 When the flap 23 is in the position ② in the middle, the flap 23 is blocked at the empty slot S corresponding to the second functional component 20, and is located between the ventilation duct W and the fan assembly 10 in the first direction (reference y axis direction) to prevent hot air from flowing back into the empty slot S corresponding to the second functional component 20. Figure 2 or Figure 6 When the flap 23 is in the first position (refer to the straight line direction of the y-axis), the flap 23 is attached to the surface of the first functional component 20 and is located on the side of the ventilation channel W away from the fan component 10 in the first direction (refer to the straight line direction of the y-axis). Figure 2 or Figure 6 Position ②) and the second station (reference Figure 2 or Figure 6 When switching between the positions ① in the figure, the opening 25 of the ventilation duct W can be crossed without blocking the opening 25. The actual size of the opening 25 of the ventilation duct W is not affected, which is conducive to maintaining the consistency of the wind pressure. The approximate trajectory of the flap 23 switching from position ① to position ② can be referred to. Figure 8 The flap 23 can be switched from position ① to position ② by superimposing a sliding motion during the reversal process, so that the flap 23 can be cut out, and the whole process is smooth.
[0061] In the related technical scheme, in order to avoid backflow, a folding plate can be set at the opening of the ventilation duct. The folding plate includes a hinged ventilation plate and a wind blocking plate. When the functional component (such as the exchange network board) is in place, the folding plate is flattened at the opening, and the ventilation plate is used to connect the installation boxes to form a mixed flow cavity. When the functional component (such as the exchange network board) is absent, the folding plate is folded and blocked at the empty slot corresponding to the absent network board to prevent hot air from flowing back to the empty slot. When the functional component (such as the exchange network board) that is not in place is reset and installed, the folding plate is pushed into the slot, and the ventilation plate, wind blocking plate and functional component (such as the exchange network board) easily form a triangular stable structure, causing the folding plate to get stuck and form a dead point, resulting in the functional component (such as the exchange network board) being blocked by the folding plate. In addition, the angle formed by the folding plate structure will also occupy a large space in the first direction (the direction of the straight line where the reference x-axis is located).
[0062] The flap 23 of the embodiment of the present application is not a folding plate structure. When the flap 23 is in the first position (refer to Figure 2 or Figure 6When the position ②) in the middle is blocked at the empty slot S corresponding to the second functional component 20, the angle unique to the folding plate structure will not be formed, and the above-mentioned triangular stable structure will not be formed. When the first functional component 20 is assembled into the empty slot S, it is not easy to be blocked by the flap 23; and, because no angle is formed, the opening 25 of the ventilation duct W formed by the first functional component 20 can be closer to the front panel 211 of the first functional component 20 facing the fan 11, thereby bringing the following effects: on the one hand, the exchange network board 22 cannot block the ventilation duct W, and more space can be reserved on the side of the ventilation duct W away from the front panel 211 to install the exchange network board 22; on the other hand, if the flap assembly 23 is far away from the front panel 211, a part of the airflow will form turbulence in the space between the ventilation duct W and the front panel 211, causing the airflow to pass through the air valve 24 to be blocked by the turbulence and unable to be discharged smoothly. The closer distance between the ventilation duct W and the front panel 211 can reduce the formation of turbulence.
[0063] The flow path of the airflow P under different working conditions is described below with reference to the accompanying drawings.
[0064] refer to Figure 1b When the fan 11 and each functional component 20 are in place and working normally, the fan 11 drives the air flow P to enter the chassis 40 through the air inlet T1 upstream of the chassis 40, pass between adjacent business boards 30, cool the business boards 30, and then enter the functional component 20 located downstream. Among them, the upstream panel of the installation box 21 (called the rear panel 212) has an upper vent for air intake. The air flow P cools the switching network board 22 in the corresponding installation box 21, and then passes through the downstream panel of the installation box 21 (the panel facing the fan 11, called the front panel 211). Since each air valve 24 is in an open state, the air flow P is directly blown downstream under the drive of the corresponding fan 11.
[0065] refer to Figure 2 , assuming that the third functional component 20 from the left is the second functional component 20, the fourth functional component 20 is the first functional component 20, and the second functional component 20 and its corresponding fan 11 are temporarily not in place due to maintenance or replacement, then the air valve 24 in the second functional component 20 corresponding to the fan 11 that is not in place is closed, and the air valves 24 of other functional components 20 in place remain open. The airflow P flowing into the first functional component 20 in place flows through the right opening 25 of the ventilation duct W to the fifth functional component 20 on the right, and the airflow 11 is discharged by the third fan 11 corresponding to the fifth functional component 20. If there is no corresponding measure, the empty slot S formed by the vacancy of the second functional component 20 that is not in place will cause hot air to flow back into it. Therefore, the flap 23 of the fourth functional component 20 (i.e., the first functional component 20) is moved from the second station (reference Figure 2 Switch to the first position (reference Figure 2Position ②), the blocking is arranged at the empty slot S corresponding to the second functional component 20 that is not in place, and is located downstream of the first direction (reference direction of the straight line where the y-axis is located) of the opening 25, so as to prevent the backflow of hot air; wherein, the width of the flap 23 can be roughly equivalent to the width of the empty slot S. The fans 11 on both sides of the empty slot S can also absorb and discharge the airflow in the empty slot S, so as to indirectly cool the two functional modules 20 adjacent to the empty slot S.
[0066] refer to Figure 3 and Figure 4 If the functional components 20 are all working normally, but some fans 11 fail or are not in place, the air valves 24 of the two functional components 20 (such as the first functional component 20 and the second functional component 20) corresponding to the fan 11 are closed, and the first functional component 20 and the second functional component 20 enter the fans 11 on both sides (the two fans 11 adjacent to the fan 11 that fails or is not in place, the first fan 11 and the third fan 11 in the figure) through the adjacent functional components 20, and the airflow P in the first functional component 20 and the second functional component 20 is driven and drawn out by the first fan 11 and the third fan 11 on both sides.
[0067] Combination Figures 9a to 17c In a specific embodiment, the heat dissipation system also includes a first reset component corresponding to the flap 23 one by one, and the first reset component is used to provide the corresponding flap 23 with an elastic restoring force F1 for resetting from the second position (reference position ①) to the first position (reference position ②), so that after the corresponding first functional component 20 is pulled out, the flap 23 can automatically reset from the second position (reference position ①) to the first position (reference position ②), and in the absence of external force, the flap 23 is maintained at the first position (reference position ②), and there is no need to manually adjust the position of the flap 23, so that hot air backflow is automatically prevented in a manpower-saving manner, and the flap 23 is fixed at position ② without additional operation, which is convenient to operate.
[0068] Combination Figures 9a to 16cIn a specific embodiment, the first reset component includes a support portion 26 and an elastic portion (in some cases, the elastic portion 27 and the elastic portion 27' can be referred to), the support portion 26 has a first end A and a second end B relative to each other, the first end A is rotatably connected to the first functional component 20 around a first rotation axis L1 in a third direction (the direction of the straight line where the reference z-axis is located), and the second end B acts on the flip plate 23, the third direction (the direction of the straight line where the reference z-axis is located) is perpendicular to the first direction (the direction of the straight line where the reference y-axis is located) and the second direction (the direction of the straight line where the reference x-axis is located); the root end of the flip plate 23 is slidably connected to a slide rail 231 extending along the first direction (the direction of the straight line where the reference y-axis is located) on the corresponding first functional component 20, and the slide rail 231 is located between the first station (reference position ②) and the second station (reference position ①) of the flip plate 23; the elastic portion is used to drive the support portion 26 to rotate around the first rotation axis L1 relative to the flip plate 23, so as to drive the flip plate 23 to reset from the second station (reference position ①) to the first station (reference position ②).
[0069] When the flap 23 is in the second position (reference position ①), the elastic part is squeezed by the flap 23 to deform and is in an energy storage state. Once the second functional component 20 is taken out, the flap 23 is released from the limit, and the elastic part drives the support part 26 to rotate around the first rotation axis L1. Figures 9a to 16c Specifically, the rotation is counterclockwise. Since the root end of the flap 23 is confined in the slide rail 231, it can only slide back and forth along the first direction (reference to the straight line direction where the y-axis is located). While the flap 23 is driven by the support part 26 to rotate counterclockwise around the root end of the flap 23, the entire flap 23 will be pushed by the support part 26 to move along the first direction (reference to the straight line direction where the y-axis is located) toward the front panel 211. The root end of the flap 23 moves to the end of the slide rail 231 close to the front panel 211, and the flap 23 rotates to be parallel to the front panel 211 and perpendicular to the first direction (reference to the straight line direction where the y-axis is located). At this time, the flap 23 is in the first working position (reference position ②), and the elastic energy release of the elastic part is partially or completely released, and is in an energy release state.
[0070] There are many ways for the elastic part to drive the support part 26 to rotate relative to the flap 23 around the first rotation axis L1, and drive the flap 23 to return from the second position (reference position ①) to the first position (reference position ②).
[0071] refer to Figures 11a to 11c , Figures 12a to 12c , Figures 13a to 13c ,as well as, Figures 15a to 15c In a specific embodiment, the second end B of the support portion 26 is rotatably connected to the flap 23 about a second rotation axis L2 in a third direction (reference direction of the straight line where the z-axis is located). Fig.11c , Fig.12c , Fig.13c as well as Fig.15c When the flap 23 is in the second position (refer to Fig.11a , Fig.12a , Fig.13a as well as Fig.15a When in position ①), a second angle b is formed between the flap 23 and the support portion 26; an elastic portion 27' is provided at the second rotation axis L2, and the elastic portion 27' is used to provide an elastic restoring force for the flap 23 and the support portion 26 to rotate around the second rotation axis L2, so that the flap 23 has a tendency to maintain the first angle a with the support portion 26.
[0072] Among them, Fig.11a In the embodiment, the first rotation axis L1 is located near the slide rail 231, the length of the support portion 26 is short, and the first angle a is greater than the second angle b. The flap 23 is in the second position (refer to Fig.11a When the elastic part 27' is in the energy storage state, it provides the elastic restoring force F1 for the support part 26 and the flap 23 to expand from the second angle b to the first angle a, and the flap 23 is driven to rotate counterclockwise around the first rotation axis L1. At the same time, the support part 26 is also driven to rotate counterclockwise. The intermediate state of the rotation process can be referred to Fig.11b During this process, since the root end of the flap 23 is not fixed but limited to move along the slide rail 231, during the rotation of the flap 23 around the first rotation axis L1, its root end will be driven by the elastic part 27' to move along the slide rail 231 toward the front panel 211, and the flap 23 combines the rotation and translation movements until it reaches the first station (refer to Fig.11c Position ②), reference Fig.11c , the angle between the support portion 26 and the flap 23 is expanded to the first angle a, and the elastic portion 27' is in the energy release state. When the second functional component 20 adjacent to the first functional component 20 is reset and installed, a force F2 is applied to the flap 23, and the second functional component 20 drives the flap 23 to return to the second position along the opposite trajectory (refer to Fig.11a position ①), and at the same time drives the support portion 26 to return to the position along the reverse trajectory. Fig.11a When the elastic portion 27' is in the middle position, the elastic portion 27' returns from the energy releasing state to the energy storing state.
[0073] And in Figures 12a to 12c , Figures 13a to 13c ,as well as, Figures 15a to 15c In the embodiment, the first rotation axis L1 is located near the opening 25 away from the slide rail 231, the length of the support portion 26 is relatively long, and the first angle a is smaller than the second angle b. The flap 23 is in the second position (refer to Fig.12a , Fig.13a and Fig.15aWhen the elastic part 27' is in the energy storage state, it provides the support part 26 and the flap 23 with an elastic restoring force F1 that reduces the second angle b to the first angle a, and the flap 23 is driven to rotate counterclockwise around the first rotation axis L1. At the same time, the support part 26 is also driven to rotate counterclockwise. The intermediate state of the rotation process can be referred to Figure 12b , Fig.13b and Fig.15b In this process, since the root end of the flap 23 is not fixed but limited to move along the slide rail 231, during the rotation of the flap 23 around the first rotation axis L1, its root end will be driven by the elastic part 27' to move along the slide rail 231 toward the front panel 211, and the flap 23 combines the rotation and translation movements until it reaches the first station (refer to Fig.12c , Fig.13c and Fig.15c Position ②), continue to refer to Fig.12c , Fig.13c and Fig.15c , the angle between the support portion 26 and the flap 23 is reduced to the first angle a, and the elastic portion 27' is in the energy release state. When the second functional component 20 adjacent to the first functional component 20 is reset and installed, a force F2 is applied to the flap 23, and the adjacent second functional component 20 drives the flap 23 to return to the second position clockwise along the opposite trajectory (refer to Fig.12a , Fig.13a and Fig.15a At the same time, the support portion 26 is driven to return clockwise to the position ① along the reverse trajectory. Fig.12a , Fig.13a and Fig.15a When the elastic portion 27' is in the middle position, the elastic portion 27' returns from the energy releasing state to the energy storing state.
[0074] refer to Figures 11a to 11c In a specific embodiment, the first rotating shaft L1 is slidably connected to the first functional component 20 along the second direction (referenced to the straight line direction where the x-axis is located). Specifically, the first rotating shaft L1 can be slidably matched in the guide rail 233. The guide rail 233 is provided on the first functional component 20 and extends along the second direction (referenced to the straight line direction where the x-axis is located). The guide rail 233 limits the first rotating shaft L1 to move only along the second direction (referenced to the straight line direction where the x-axis is located). Therefore, when the elastic part 27' drives the flap 23 to the first station (referenced to Fig.11c During the swinging process of position ②), the first rotation axis L1 can move along the second direction (reference direction of the straight line where the x-axis is located) away from the flap 23 to prevent the flap 23 and the support portion 26 from being stuck during the swinging process.
[0075] In a specific embodiment, reference Figures 9a to 9c , Figures 10a to 10c , Figures 12a to 12c , Figures 13a to 13c , Figures 14a to 14c , Figures 16a to 16c The first rotation axis L1 is provided with an elastic part, which is used to provide an elastic restoring force F1 for the support part 26 to rotate around the first rotation axis L1, so as to move the flap 23 from the second station (reference Figure 9a , Fig.10a , Fig.12a , Fig.13a , Fig.14a and Fig.16a Position ①) reset to the first position (reference Fig.9c , Fig.10c , Fig.12c , Fig.13c , Fig.14c and Fig.16c Position②). Among them, Figures 12a to 12c In, and Figures 13a to 13c In the embodiment, corresponding elastic parts are respectively arranged at the first rotation axis L1 and the second rotation axis L2. Fig.12a and Fig.13a When the flap 23 is in position ①), once the limit is released, the elastic part drives the support part 26 to rotate counterclockwise around the first rotation axis L1. The flap 23 is moved by the support part 26 to rotate counterclockwise around the root end, and the entire flap 23 is moved by the support part 26 along the first direction (reference y axis linear direction) toward the front panel 211, integrating the rotation and translation movements, and the flap 23 arrives at the first position (reference y axis linear direction). Fig.12c and Fig.13c position ②), the elastic part is in an energy release state.
[0076] exist Figures 9a to 9c ,as well as, Figures 16a to 16c In the figure, the elastic part is located at the first rotating shaft L1, which is not shown in the figure. The elastic part and the supporting part 26 form an integrated spring sheet to simplify the assembly process. During production, an elastic curved sheet structure can be formed at the second end B of the supporting part 26 as the elastic part. The elastic curved structure and the supporting part 26 are an integrated structure and can be fixed to the first rotating shaft L1 through the end.
[0077] Similarly, the elastic portion at the second rotation axis L2 in other figures may also form an integrated elastic sheet with the support portion 26 .
[0078] Figures 10a to 10c , Figures 12a to 12c , Figures 13a to 13c ,as well as, Figures 14a to 14cIn the embodiment, the elastic part 27 and the support part 26 at the first rotating shaft L1 are independent structures, the elastic part 27 can be a torsion spring, and the support part 26 is a support rod. The torsion spring is sleeved on the first rotating shaft L1, one end of which is fixed to the first rotating shaft L1, and the other end is fixed to the support part 26. Similarly, the elastic part 27' at the second rotating shaft L2 can also be a torsion spring, one end of which is fixed to the support part 26, and the other end is fixed to the flap 23. The torsion spring is installed later, which is convenient for simplifying the structure of the support part 26, and there is no need to process an elastic curved sheet structure as the elastic part.
[0079] The support portion 26 moves the flap 23 from the second station (reference Fig.10a , Fig.12a , Fig.13a and Fig.14a Position ①) reset to the first position (reference Fig.10c , Fig.12c , Fig.13c and Fig.14c The position ②) can have various forms, which are specifically related to the connection form between the support portion 26 and the flap 23.
[0080] In a specific embodiment, the second end B of the support portion 26 close to the flap 23 is slidably matched with the flap 23. Figures 9a to 9c , Figures 10a to 10c ,as well as, Figures 16a to 16c In the embodiment, the support portion 26 and the flap 23 are not locked, but the support portion 26 is allowed to slide relative to each other during the process of moving the flap 23 to avoid getting stuck during the rotation process.
[0081] There are many ways for the support portion 26 to slide with the flap 23. Figures 10a to 10c In a specific embodiment, the second end B of the support portion 26 close to the flap 23 forms a moving pair with the flap 23, and specifically, the second rotation axis L2 can be slidably matched in the guide track 232 on the flap 23, so that the support portion 26 and the flap 23 can move in coordination with each other within a stable trajectory; or, refer to Figures 9a to 9c ,as well as, Figures 16a to 16c In another specific embodiment, the second end B of the support portion 26 close to the flap 23 is elastically abutted against the flap 23 in a sliding manner. The second end 23 of the support portion 26 can be specifically provided with an elastic protrusion 261 bulging in the direction of the flap 23. The elasticity of the elastic protrusion 261 is utilized to always maintain elastic abutment with the flap 23 to ensure that the support portion 26 maintains contact with the flap 23 and can slide relative to each other.
[0082] In a specific embodiment, reference Figures 9a to 9c , Figures 10a to 10c , Figures 11a to 11c ,as well as, Figures 12a to 12c, the extension track of the slide rail 231 is a straight track to ensure smooth sliding of the first rotation axis L1; or, refer to 13a to Fig.13c , Figures 14a to 14c , Figures 15a to 15c ,as well as, Figures 16a to 16c In another specific embodiment, the extension trajectory of the slide rail 231 is a curved trajectory that is recessed into the internal space of the corresponding first functional component 20. During the swinging of the support portion 26 and the flap 23, a redundant amount is provided for the support portion 26 to move toward the internal space of the corresponding first functional component 20, thereby preventing the support portion 26 and the flap 23 from being stuck, and preventing the flap 23 from being stuck by the adjacent first functional component 20.
[0083] For example, Figures 16a to 16c Relative to Figures 9a to 9c The difference is that the slide rail 231 is changed from a straight track to a curved track recessed toward the inner space of the corresponding first functional component 20 .
[0084] For another example, Figures 13a to 13c Relative to Figures 12a to 12c The difference is that the slide rail 231 is changed from a straight track to a curved track recessed toward the inner space of the corresponding first functional component 20 .
[0085] and Figures 13a to 13c Compared with the technical solutions Figure 17a to Figure 17a The difference is that the slide rail 231 is removed, and the position of the first rotation axis L1 is moved a certain distance toward the inner space of the installation box 21 along the negative direction of the x-axis, and the support portion 26 can be a rigid rod to facilitate the stability of the operation of the flip plate 23. In addition, a receiving groove t can be provided on the side wall of the first functional component 20 (such as the side wall of the installation box 21), and the receiving groove t is located on the side of the opening 25 away from the front panel 211, so that when the flip plate 23 is in the second position (reference Fig.13a When the flap 23 is in position ①), the flap 23 can be accommodated in the receiving groove t to hide the flap 23 and avoid blocking the second functional component 20. The following is a brief introduction to its operation process in conjunction with the accompanying drawings: Fig.17a , the flap 23 is in the second position (reference Fig.17a Position in ①); reference Fig.17bWhen the second functional component 20 is pulled out, the flap 23 loses its limit position, and the elastic part 27 at the first rotation axis L1 drives the support part 26 to rotate counterclockwise. When the support part 26 rotates counterclockwise, it drives the flap 23 to swing around the first rotation axis L1, and the elastic part 27' at the second rotation axis L2 reduces the angle between the flap 23 and the support part 26; wherein, the flap 23 and the support part 26 are hinged through the first rotation axis L1, which is equivalent to the flap 23 being supported by the support part 26 through the entire first rotation axis L1, and there is no problem of shaking due to insufficient fulcrum points; the angle between the flap 23 and the support part 26 can be adjusted by the elastic restoring force of the elastic part 27'; refer to Fig.17c Under the joint action of the elastic part 27 and the elastic part 27', the flap 23 reaches the first position (refer to Fig.17c The support portion 26 is also in a position substantially parallel to the front panel 211. When the second functional component 20 is inserted back, the flap 23 and the support portion 26 are driven to return to the second position in the reverse direction along the original path (refer to Fig.13a Position in ①). Figures 13a to 13c The slide rail 231 is provided in the middle to facilitate the stable operation of the flap 23. Figures 17a to 17c In the technical solution, after the slide rail 231 is removed, the restriction on the flap 23 can be reduced, which is beneficial to reducing the occurrence of the flap 23 and the slide rail 231 getting stuck.
