[0001] This application relates to the field of detachable devices, and more particularly to a pull-out device, a heat exchange device, and an energy storage system. Background Technology

[0002] In related technologies, pull-out devices are widely used in various equipment, such as server racks and energy storage cabinets, to meet the needs of on-site commissioning, maintenance, and repair of energy storage systems. They are used to install and pull out various components for easy maintenance and management. However, existing pull-out devices are often complex to operate during locking and unlocking, and lack stability. They are prone to shaking during the pulling process, and may even produce abnormal noises, affecting the normal operation of the equipment. Utility Model Content

[0003] This application provides a pull-out device, a heat exchange device, and an energy storage system, which are simple in structure, easy to operate, have good stability, and are free from abnormal noise, thereby at least partially solving the above-mentioned technical problems.

[0004] To achieve the above objectives, according to a first aspect of this application, a pull-out device is provided, comprising:

[0005] The mounting frame includes a base frame and two side frames connected to the base frame, and the base frame is provided with a fixing buckle;

[0006] The pull-out assembly has a movable buckle on the first side facing the bottom frame. When the pull-out assembly is separated from the fixed frame, the movable buckle is in a first state; when the pull-out assembly is locked to the fixed frame, the movable buckle is in a second state and locks in conjunction with the fixed buckle.

[0007] In some embodiments, the fastener includes a fixing part and a receiving part connected to the fixing part. The fixing part is fixedly connected to the bottom frame, and the receiving part is bent to form a receiving groove with the fixing part.

[0008] The movable buckle includes a buckle head and a rotatable swing arm. The first end of the swing arm is connected to a first side, and the buckle head is connected to the second end of the swing arm and mates with a receiving groove.

[0009] In some embodiments, the pull-out assembly further includes a mounting plate rotatably connected to the movable buckle; the movable buckle further includes an elastic element, one end of which is connected to the swing arm and the other end of which is connected to the mounting plate.

[0010] In some embodiments, at least two fixed buckles are provided, and the number of movable buckles is the same as that of fixed buckles, with each movable buckle corresponding to each fixed buckle.

[0011] In some embodiments, the pull-out assembly further includes a first buffer portion disposed on a first side. When the pull-out assembly is locked to the fixed frame, the first buffer portion abuts against the bottom frame and is compressed.

[0012] In some embodiments, the pull-out assembly further includes a second buffer portion disposed on a second side of the pull-out assembly facing the side frame. The side frame is provided with a protrusion. When the pull-out assembly is locked to the fixing frame, the second buffer portion abuts against the protrusion and is compressed.

[0013] In some embodiments, the fixing frame further includes a back frame with reinforcing ribs, and the pull-out assembly further includes a third buffer portion disposed on the third side of the pull-out assembly facing the back frame. When the pull-out assembly is locked in the fixing frame, the third buffer portion abuts against the reinforcing ribs and is compressed.

[0014] In some embodiments, both side frames of the fixing frame are inclined outward to increase the opening formed by the two side frames and the bottom frame, and the pull-out assembly is arranged in a trapezoidal shape.

[0015] In some embodiments, the pull-out assembly further includes a handle disposed on a fourth side of the pull-out assembly, the fourth side being opposite to the first side.

[0016] According to a second aspect of this application, a heat exchange device is provided, including the aforementioned pull-out device and a heat exchange assembly, wherein the heat exchange assembly is disposed on the pull-out device.

[0017] According to a third aspect of this application, an energy storage system is provided, including the heat exchange device described above and a cabinet, wherein the heat exchange device is installed inside the cabinet.

[0018] The technical advantage of this application lies in providing a pull-out device that enables quick locking and unlocking of the pull-out assembly through the cooperation of a movable buckle and a fixed buckle, requiring no additional operation from the user and simplifying the installation process. Specifically, when the pull-out assembly is separated from the fixed frame, the movable buckle is in a first state (unlocked state); when the pull-out assembly is locked to the fixed frame, the movable buckle is in a second state (locked state) and engages with the fixed buckle for locking, allowing the pull-out assembly to freely switch between the first and second states. Furthermore, the stable installation of the pull-out assembly and the fixed frame improves the stability of the pull-out device, preventing shaking during the pulling process and reducing vibration or abnormal noise during transportation or operation. In addition, by using the aforementioned pull-out device, the heat exchange device and energy storage system of this application facilitate the installation and maintenance of the heat exchange components, improving the overall performance of the equipment.

Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0034] This application provides a pull-out device for installation in a server rack, for example, an energy storage device, where the pull-out device is detachably installed in the rack.

[0035] like Figure 1 As shown, the pull-out device includes a fixed frame 100 and a pull-out assembly 300.

[0036] like Figures 2-3 As shown, the fixing frame 100 includes a base frame 110 and two side frames 120 connected to the base frame 110. The base frame 110 is provided with fixing buckles 200.

[0037] like Figures 2-4 As shown, the pull-out assembly 300 is detachably mounted on the fixed frame 100. The pull-out assembly 300 includes a mounting plate 310 and a movable buckle 320 rotatably disposed on a first side 311 of the mounting plate 310. When the pull-out assembly 300 is separated from the fixed frame 100, the movable buckle 320 is in a first state (unlocked state). When the pull-out assembly 300 is installed, the fixed buckle 200 is in a second state (locked state). That is, when the movable buckle 320 and the fixed buckle 200 switch from the first state to the second state, the movable buckle 320 is in the second state and cooperates with the fixed buckle 200 to lock, so that the pull-out assembly 300 is locked to the fixed frame 100.

[0038] like Figure 1 and Figure 2 As shown, the mounting bracket 100 has multiple threaded holes and can be detachably connected to the cabinet using screws. The pull-out assembly 300 is installed on the mounting bracket 100, and after the mounting bracket 100 is installed in the cabinet, the mounting plate 310 performs its function in the cabinet.

[0039] like Figure 1 and Figure 2 As shown, the pull-out assembly 300 is detachably mounted on the fixing frame 100, so that the fixing frame 100 can be equipped with different pull-out assemblies 300, that is, different mounting plates 310.

[0040] like Figure 1 and Figure 2As shown, when the pull-out assembly 300 is installed, the first side 311 of the mounting plate 310 faces the bottom frame 110, and the movable buckle 320 moves towards the bottom frame 110. The movable buckle 320 switches from the first state to the second state by abutting against the fixed buckle 200, thereby achieving the locking of the movable buckle 320 and the fixed buckle 200. This means that when the pull-out assembly 300 is installed on the fixed frame 100, the user does not need to perform any additional operations, making the installation process simple and convenient. Furthermore, the pull-out assembly 300 and the fixed frame 100 are stably fastened together, which can reduce vibration or abnormal noise generated during transportation or operation of the pull-out device.

[0041] like Figure 4 and Figure 5 As shown, the fixing buckle 200 includes a fixing part 210 and a receiving part 220 connected to the fixing part 210. The fixing part 210 is fixedly connected to the bottom frame 110, and the receiving part 220 is bent to form a receiving groove 3200 with the fixing part 210.

[0042] like Figure 4 As shown, the movable buckle 320 includes a buckle head 321 and a rotatable swing arm 322. The first end of the swing arm 322 is connected to the first side 311, and the buckle head 321 is connected to the second end of the swing arm 322 and engages with the receiving groove 3200. It can be understood that the swing arm 322 is rotatably connected to the mounting plate 310. When the movable buckle 320 is in its first state, and the pull-out assembly 300 is installed, the buckle head 321 abuts against the fixing part 210, driving the swing arm 322 to rotate so that the buckle head 321 enters the receiving groove 3200, thereby switching the movable buckle 320 to its second state and engaging with the fixed buckle 200 for locking.

[0043] In some embodiments, such as Figure 4 As shown, when the active buckle 320 is in the first state ( Figure 4 In the middle state), the swing arm 322 extends in the direction toward the bottom frame 110, so that the buckle 321 is aligned with the fixing part 210 of the fixing buckle 200. The receiving part 220 is located on one side of the buckle 321 (for example, the lower side). During the installation of the pull-out assembly 300, the buckle 321 abuts against the bottom frame 110 (see...). Figure 3 ), and drive the swing arm 322 to rotate, for example, the swing arm 322 rotates counterclockwise, and the movable buckle 320 switches from the first state to the second state. Figure 6 In the middle state, the buckle 321 is driven to move downward so that the buckle 321 enters the receiving part 220. The receiving part 220 is generally a U-shaped groove. The buckle 321 is limited by the receiving part 220, thereby realizing the locking engagement between the movable buckle 320 and the fixed buckle 200.

[0044] In some embodiments, such as Figure 4As shown, buckle 321 is a roller, so that when buckle 321 abuts against fixed part 210, buckle 321 can slide along fixed part 210 to drive swing arm 322 to rotate, avoiding buckle 321 rigidly abutting against fixed part 210, which would cause buckle 321 or swing arm 322 to be damaged.

[0045] In some embodiments, such as Figure 4 As shown, the movable buckle 320 also includes an elastic element 323. One end of the elastic element 323 is connected to the swing arm 322, and the other end is connected to the mounting plate 310. When the movable buckle 320 switches from the first state to the second state, the swing arm 322 rotates in the first direction, and the elastic element 323 is compressed and stores energy. When the pull-out assembly 300 is disassembled, the buckle head 321 separates from the receiving groove 3200, and the elastic element 323 is released to drive the swing arm 322 to rotate in the second direction, so that the movable buckle 320 switches from the second state to the first state.

[0046] The elastic element 323 includes a housing and a torsion spring, with the torsion spring disposed within the housing to form an integral structure, facilitating installation on the mounting plate 310 and reducing the complexity of handling multiple parts individually. For example, one end of the torsion spring is fixed inside the housing of the elastic element 323, and the other end extends out of the housing and connects to the swing arm 322. When the movable buckle 320 is not in contact with the base frame 110, the spring force of the torsion spring holds the swing arm 322 in position, thereby holding the movable buckle 320 in a first state. When the buckle 321 abuts against the base frame 110 and drives the swing arm 322 to rotate in a first direction, such as counterclockwise, the torsion spring is compressed. When the pull-out assembly 300 is disassembled, the buckle 321 separates from the receiving groove 3200, causing the buckle 321 to disengage from the limit position. The torsion spring is released to drive the swing arm 322 to rotate in the second direction, such as clockwise, so that the buckle 321 abuts against the fixing part 210 again under the action of the elastic force, and provides a force away from the fixing part 210 (bottom frame 110), making it easy for the user to disassemble.

[0047] In some embodiments, at least two fixed buckles 200 are provided, symmetrically arranged on the bottom frame 110, and the number of movable buckles 320 is the same as that of fixed buckles 200, with each movable buckle 320 corresponding to each fixed buckle 200.

[0048] like Figure 2 and Figure 3 As shown, there are two fixed buckles 200 and two movable buckles 320. One fixed buckle 200 is located in the upper middle part of the bottom frame 110, and the other fixed buckle 200 is located in the lower middle part of the bottom frame 110. The movable buckle 320 corresponds to the fixed buckle 200. This arrangement makes the cooperation between the pull-out assembly 300 and the fixing bracket 100 more stable.

[0049] like Figure 1 , Figure 2 and Figure 6 As shown, the pull-out assembly 300 also includes a first buffer portion 330, which is disposed on the first side 311 of the mounting plate 310. When the pull-out assembly 300 is locked to the fixing frame 100, the first buffer portion 330 abuts against the bottom frame 110 and the first buffer portion 330 is compressed.

[0050] The first buffer portion 330 has a certain degree of flexibility and is located between the mounting plate 310 and the fixing frame 100 to provide a buffering effect, thereby reducing the impact of relative vibration between the two and reducing noise. For example, the first buffer portion 330 is made of foam, which is compressed by the pull-out assembly 300 and the bottom frame 110 of the fixing frame 100, thus providing a good buffering effect and reducing vibration and noise. For example, if the first side 311 of the mounting plate 310 is arranged along the X direction, the first buffer portion 330 provides a buffering effect in the X direction.

[0051] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the pull-out assembly 300 also includes a second buffer portion 340, which is disposed on the second side 312 of the mounting plate 310. The side frame 120 of the fixing bracket 100 is provided with a protrusion 140. When the pull-out assembly 300 is locked in the fixing bracket 100, the second buffer portion 340 abuts against the protrusion 140 and the second buffer portion 340 is compressed.

[0052] In some embodiments, the second buffer portion 340 includes foam, and a protrusion 140 protrudes from the side frame 120 of the fixing bracket 100. For example, the protrusion 140 is generally frustum-shaped and can compress the foam with the second side 312 of the mounting plate 310 to provide a buffering effect. At the same time, it reduces the contact area between the protrusion 140 and the second buffer portion 340, thereby reducing the friction between the second buffer portion 340 and the protrusion 140 when the pull-out assembly 300 is installed or removed, making it easier for the pull-out assembly 300 to be pulled out. For example, if the second side 312 of the mounting plate 310 is arranged along the Y direction, the second buffer portion 340 provides a buffering effect in the Y direction.

[0053] like Figure 1 , Figure 2 and Figure 6 As shown, the pull-out assembly 300 also includes a third buffer 350, which is disposed on the third side 313 of the pull-out assembly 300 facing the back frame 130. The fixing frame 100 also includes the back frame 130, which is provided with a reinforcing rib 150. When the pull-out assembly 300 is locked to the fixing frame 100, the third buffer 350 abuts against the reinforcing rib 150, and the third buffer 350 is compressed.

[0054] In some embodiments, the third buffer portion 350 includes foam, and the back frame 130 abuts against the third buffer portion 350 by reinforcing ribs 150, causing the reinforcing ribs 150 and the third side 313 of the mounting plate 310 to compress the foam, thereby providing a buffering effect. For example, the third side 313 of the mounting plate 310 is arranged along the Z direction, and the third buffer portion 350 provides a buffering effect in the Z direction. The first buffer portion 330, the second buffer portion 340, and the third buffer portion 350 provide buffering effects in the X, Y, and Z directions of the mounting plate 310, thereby ensuring comprehensive and effective buffering between the mounting plate 310 and the fixing frame 100, which can significantly reduce the gap between the pull-out assembly 300 and the fixing frame 100, thereby reducing vibration and noise during transportation or operation.

[0055] The first buffer section 330, the second buffer section 340, and the third buffer section 350 are all glued to the mounting plate 310.

[0056] like Figure 2 As shown, the two side frames 120 of the fixing frame 100 are inclined outward to increase the opening formed by the two side frames 120 and the bottom frame 110, and the pull-out assembly 300 is arranged in a trapezoidal shape.

[0057] The inclined arrangement of the two side frames 120 makes the fixing bracket 100 roughly trapezoidal in shape, matching the pull-out assembly 300. The trapezoidal shape increases the opening for the pull-out assembly 300 to be installed, facilitating installation.

[0058] like Figure 1 and Figure 2 As shown, the pull-out assembly 300 also includes a handle 360, which is disposed on a fourth side 314 of the pull-out assembly 300, opposite to the first side 311. For example, the handle 360 ​​is connected to the mounting plate 310 and located on the fourth side 314 of the pull-out assembly 300.

[0059] The fourth side 314 is located on the outside of the mounting plate 310, that is, on the side away from the bottom frame 110. When the pull-out assembly 300 is mounted on the bracket 100, the handle 360 ​​(see...) Figure 7 It is exposed outside the mounting bracket 100 and can be operated by the user. For example, there are two handles 360, which are symmetrically arranged on the fourth side 314 of the mounting plate 310 for easy operation by the user.

[0060] like Figures 2-4 As shown, when disassembling the pull-out assembly 300, the user holds the handle 360 ​​and pulls the pull-out assembly 300, causing the buckle 321 of the movable buckle 320 to disengage from the receiving groove 3200 of the fixed buckle 200. Even if the pull-out assembly 300 is disconnected from the fixed frame 100, pulling the pull-out assembly 300 causes it to slide relative to the fixed frame 100, thereby disengaging from the fixed frame 100 and completing the disassembly.

[0061] It is worth noting that the engagement between the movable buckle 320 and the receiving groove 3200 will only disengage when a certain force is applied. That is, the user operation can disengage the pull-out assembly 300 from the fixed frame 100, but when the user does not operate, the pull-out device is subjected to external vibration, and the movable buckle 320 and the receiving groove 3200 can maintain engagement, so that the pull-out assembly 300 is stably locked in engagement with the fixed frame 100.

[0062] This application embodiment also provides a heat exchange device, including the aforementioned pull-out device and a heat exchange component 370. The heat exchange component 370 is disposed on the pull-out device and can be easily pulled out or pushed in from the pull-out device, simplifying the maintenance and cleaning process, reducing downtime, and improving the maintainability of the equipment. The heat exchange device can be used to heat, cool, or maintain the temperature of process fluids.

[0063] For example, such as Figure 2 As shown, the mounting plate 310 has mounting holes 3100, and the heat exchange component 370 is installed in the mounting holes 3100. The heat exchange component 370 can be a fan or a heat exchanger. Since the pull-out device in the energy storage system provided in this application has the same technical features as the above-mentioned pull-out device, the two can solve the same technical problems and achieve the same technical effects.

[0064] This application also provides an energy storage system, including the aforementioned heat exchange device and a cabinet, with a pull-out device installed inside the cabinet. The heat exchange device is used to dissipate heat from heat-generating components (chips, energy storage modules, etc.) inside the cabinet. Since the heat exchange device in the energy storage system provided in this application has the same technical features as the aforementioned heat exchange device, both can solve the same technical problems and achieve the same technical effects.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more features.
