Technical Field

[0001] The utility model relates to the technical field of server cabinets, in particular to a server charging cabinet with multi-channel power supply and convenient disassembly and assembly of each server unit. Background Art

[0002] The projector server uses digital storage and projection technology to provide a more flexible and high-quality projection experience. Current projectors are often equipped with multiple server units. In addition to core components such as the central processing unit, motherboard, memory, and hard disk, each server unit is also equipped with a power module to maintain power supply for a short period of time, making it easier to replace and assemble between multiple projectors. In order to prevent adverse conditions such as data loss and hardware damage, the server unit needs to be kept powered for a long time.

[0003] The projector will be equipped with a power supply module on the cabinet. Many of the current power supply modules connect the AC power to the centralized power module in the cabinet for power conversion and then use the power cord to connect the power input terminal of each server unit. The assembly and fixation of each server unit to the cabinet are mainly done by tightening screws. After assembly and fixation, the power cord is plugged in. When multiple server units are installed on the same cabinet, since the power supply module and the power output terminals of each server unit are built-in relative to the cabinet, it is easy to make the power cord plugging inconvenient due to space limitations. Utility Model Content

[0008] On the basis of the above technical solution, a fan is arranged on the fourth plate body and / or the fifth plate body, and the wind force is directed parallel to the left and right directions when the fan is working.

[0009] On the basis of the above technical solution, each of the guide rails is a horizontally arranged strip structure in the front-to-back direction, and its longitudinal cross-sectional profile on the left and right planes is a "C"-shaped structure with the opening facing inward. The opening constitutes the sinking groove, and the upper end surface of the sinking groove is an inclined surface structure that is higher in the front and lower in the back, so that the sinking groove constitutes a guiding structure that is wide in the front and narrow in the back.

[0010] On the basis of the above technical solution, guide openings are provided on the front and rear sides of the sink, and the guide openings are horizontal "V"-shaped structures that are wide outside and narrow inside.

[0011] On the basis of the above technical solution, a positioning piece is provided near the rear area of ​​the sink, and the positioning piece has a positioning flange structure that can be elastically deformed longitudinally. A positioning hole that is compatible with the positioning piece is provided on the server unit. After the server unit is inserted into place in the sink, the positioning piece can be embedded in the positioning hole.

[0012] On the basis of the above technical solution, the bottom of the positioning flange structure is provided with a rounded corner, and the top of the positioning hole is provided with a conical opening structure.

[0013] On the basis of the above technical solution, a buffer strip capable of longitudinal elastic deformation is fixedly connected to the upper end surface of the sink groove, and an abutment strip is fixedly connected to the bottom of the buffer strip.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to an element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0029] The utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1: See Figures 1 to 5 The present embodiment discloses a server charging cabinet, including a cabinet 1 with a rectangular cabinet structure, wherein the cabinet 1 is formed by splicing a first plate 11, a second plate 12, a third plate 13, a fourth plate 14 and a fifth plate 15. During actual processing, the edges of the spliced ​​plates are locked and connected by a flange structure and bolts. In other embodiments, the connection can also be made by welding or a snap-on structure.

[0031] In this embodiment, the first plate body 11 is a horizontal "U"-shaped structure located at the rear side, with its open side facing the front, and the left and right sides are also open structures, which can close the top, rear and bottom space of the cabinet 1. Four longitudinally spaced sockets 5 are arranged on the vertical plate body of the first plate body 11, and the external power plug 7 can pass through the socket 5 and be connected to the power input terminal of the server unit 3 located inside.

[0032] The second plate 12 is connected to the front opening side of the first plate 11, and the third plate 13 is attached to the inner end of the first plate 11. The middle parts of the second plate 12 and the third plate 13 are provided with insertion holes that penetrate front and back. The insertion holes are used for the server unit 3 to enter and exit the cabinet 1, which also makes the second plate 12 and the third plate 13 form a rectangular frame structure. It should be noted that the outline of the insertion hole on the third plate 13 is slightly smaller than the insertion hole on the second plate 12, so that the third plate 13 forms a front and rear limit structure. In actual use, after the server unit 3 is inserted inward, it can be used to form a preliminary positioning and provide a screw installation space, and a more solid connection structure can be formed between the server unit 3 and the third plate 13 by screws.

[0033] The fourth plate 14 and the fifth plate 15 are vertical plate structures arranged on the left and right sides of the first plate 11, and the fourth plate 14 and the fifth plate 15 are evenly distributed with a plurality of left and right ventilation hole structures, so that air can circulate inside and outside the cabinet 1 to facilitate internal heat dissipation.

[0034] Furthermore, eight fans 4 are connected to the outer wall of the fifth plate 15. The wind direction of the fans 4 when working is parallel to the left and right directions. The fan 4 in the figure is a simplified diagram. After the fan 4 is powered on, it can be used as an active heat dissipation structure to improve the heat dissipation effect. It is a prior art, and its specific structure and working principle are not repeated here. Those skilled in the art can select and implement it from the prior art according to the actual operation situation. In other embodiments, a matching fan 4 can also be configured on the fourth plate 14.

[0035] Four sets of guide rails 2 are arranged on the inner side walls of the fourth plate body 14 and the fifth plate body 15, and are used to install four server units 3. A sink groove 21 is provided on the inner side wall of each guide rail 2, and the left and right edges of the server unit 3 can be plugged in. The sink groove 21 is provided with guide openings 22 on both sides of the front and rear sides. A guide structure for accurately controlling the assembly position of the server unit 3 is also provided inside the sink groove 21.

[0036] Specifically, each of the guide rails 2 is a horizontally arranged strip structure in the front-to-back direction, and its longitudinal section profile on the left and right planes is a "C"-shaped structure with an opening facing inward, and the opening constitutes the sinking groove 21. The sinking grooves 21 on the left and right sides of the same group of guide rails 2 are arranged oppositely to form a "bracket" structure sleeved on the left and right edges of the server. The upper end surface of each sinking groove 21 is an inclined surface structure with a high front and a low rear, so that the sinking groove 21 constitutes a guide structure that is wide at the front and narrow at the rear (combined with Figure 5 shown).

[0037] Furthermore, guide openings 22 are provided on both the front and rear sides of the sink 21, and the guide openings 22 are horizontal "V"-shaped structures that are wide outside and narrow inside. The guide openings 22 on the front side are provided to facilitate the initial positioning of the server unit 3 when plugging in, and the guide openings 22 on the rear side are provided so that after plugging in, the rear end of the server unit 3 has a certain degree of freedom due to the open structure of the guide openings 22, and can slightly swing longitudinally, so that the power input end has the ability to slightly deviate during the connection operation, so as to perform the plugging operation more efficiently.

[0038] A power connector 6 is fixedly provided at the rear side end of the server unit 3. It should be noted that the server unit 3 includes a circuit board, on which core components such as a central processing unit, a mainboard, a memory, and a hard disk are arranged. An operation panel is vertically arranged at the front end of the circuit board, and a connection port is arranged on the operation panel. This is a prior art, and its specific structure and working principle are not described in detail here. Those skilled in the art can select and implement from the prior art according to actual operating conditions.

[0039] The position of the socket 5 on the first plate 11 corresponds to it one by one, and the external power plug 7 can pass through the socket 5 and be connected to the power connector 6 of the server unit 3 located on the inside. This structure exposes the power input terminal of each server, and can conveniently perform plugging and unplugging operations on the outside of the cabinet 1. Compared with the built-in settings in the prior art, the operating space is greatly improved, and the power connection can be performed quickly and efficiently. The convenient disassembly and assembly structure of the server unit 3 formed by the guide rail 2 can greatly improve its assembly convenience, which is beneficial to long-term power supply to the server unit 3 and improve the working safety and stability of the server unit 3.

[0040] Example 2, based on Example 1, combined with Figure 6As shown, in this embodiment, a positioning piece 8 is provided near the rear area of ​​the sink groove 21, and the positioning piece 8 has a locking flange structure that can be elastically deformed longitudinally. Specifically, the positioning piece 8 is a spring sheet, the middle part of which is located at a low position, and a downward ball head is provided at this position. The two ends of the positioning piece 8 have inclined parts and folded parts, which are adapted to the contour of the mounting groove 23 on the guide rail 2 to form a stable locking structure, so that the upper structure of the positioning piece 8 remains fixed, and the lower structure, as a free end, can use its own elasticity to perform longitudinal elastic deformation. The ball head constitutes the locking flange structure, and the bottom of the ball head has a smooth chamfered corner. When the server unit 3 slides laterally along the path of the sink groove 21, it can smoothly pass through the top end surface of the server unit 3. The server unit 3 is provided with a positioning hole 31 that is adapted to the positioning piece 8. After the server unit 3 is inserted into the sink groove 21 and is in place, the positioning piece 8 can be embedded in the positioning hole 31, and after the server unit 3 is laterally moved outward, the ball head of the positioning piece 8 can be easily pushed up with the help of a lateral movement to contact the positioning constraint. In order to make the ball head move in and out of the positioning hole 31 more smoothly, a conical opening structure is provided at the top of the positioning hole 31 .

[0041] Example 3, based on Example 1, combined with Figure 7 As shown, in the present embodiment, a buffer strip 25 capable of longitudinal elastic deformation is fixedly connected to the upper end surface of the sink groove 21, and an abutment strip 24 is fixedly connected to the bottom of the buffer strip 25. Specifically, the abutment strip 24 is made of hard plastic, and the buffer strip 25 is made of elastic rubber. The buffer strip 25, the abutment strip 24 and the upper end surface of the guide rail 2 are all bonded by glue. The bottom end surface of the abutment strip 24 forms an inclined surface structure with a high front and a low rear in the front-to-back direction, so that the sink groove 21 constitutes a guiding structure with a wide front and a narrow rear. Its guiding function is consistent with the guiding function in Example 1, which will not be repeated here.

[0042] Among them, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it; although the utility model is described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the utility model.
