Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a wall-mounted energy storage cabinet. Background Technology

[0002] With the development and maturation of photovoltaic and energy storage technologies, more and more households and small and medium-sized commercial environments are starting to install energy storage cabinets to be used in conjunction with photovoltaic systems or for temporary emergency power supply in households and businesses.

[0003] Although current energy storage technology has made some progress, due to limitations in energy storage requirements and battery material technology, the size of energy storage modules is still relatively large. For example, the width * height * depth mm is 700 * 200 * 1350. This means that if energy storage modules are placed directly on the ground, they may hinder users' daily activities and are also more susceptible to damage or flooding. Therefore, the market has gradually introduced wall-mounted energy storage cabinets.

[0004] However, the existing wall-mounted installation method exposes the energy storage cabinet, which poses a risk of damage to the wall connection nodes during long-term use, and is not conducive to market promotion in small and medium-sized residential groups. Therefore, this application proposes a new technical solution. Utility Model Content

[0012] The internal structural frame is equipped with a buffer balancer for using gravity to delay the lifting and lowering of the cabinet. The buffer balancer is linked to the upper part of the cabinet and the lifting part of the lifting mechanism.

[0013] Optionally, the lifting mechanism includes a guide rail, a slider, and a linear drive unit. The guide rail is vertically arranged, the slider is slidably connected to the guide rail, and the guide rail is provided with an anti-detachment structure to prevent the slider from tilting toward the structural opening of the inner structural frame.

[0015] Optionally, it also includes a controller and a fall indicator unit. The controller is electrically connected to the linear drive unit and the fall indicator unit. The fall indicator unit includes a laser generator installed at the bottom of the cabinet and / or an audible and visual alarm installed on the cabinet. The laser emitting end of the laser generator is tilted downwards, and the tilt direction is towards the lower part near the lifting mechanism.

[0016] Optionally, the controller is electrically connected to a pressure sensor for triggering movement of the slider and an alarm for abnormality of the intermediate spring. The pressure sensor is mounted on the slider, and the upper end of the intermediate spring acts on the pressure sensor.

[0017] Optionally, the cabinet has an auxiliary heat dissipation vent on the side facing the lifting mechanism, and the inner structural frame is provided with a connector for connecting an external heat sink or for the inner structural frame to be a heat-conducting structure.

[0018] Optionally, the outer end of the auxiliary heat dissipation port is turned outward to form a protective edge.

Furthermore, because the cabinet can be pulled back into the inner structural frame, it can further reduce space occupation, which is conducive to its promotion in small and medium-sized apartments and other places.

[0024] At the same time, the above-mentioned settings can also reduce the risk of the cabinet falling due to damage to the installation structure, and can protect it with the internal structural frame, which can effectively improve the safety of the energy storage structure.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0030] This application discloses a wall-mounted energy storage cabinet.

[0031] Reference Figure 1 and Figure 2 The wall-mounted energy storage cabinet includes a cabinet body 1 and an energy storage module. The cabinet body 1 is rectangular in shape, hollow inside, and has an opening to the outside on at least one side. The opening is closed by screws fixing a suitable cover plate. The energy storage module includes interconnected battery packs, the circuit structure corresponding to the BMS system, and an inverter functional module, which are integrated and installed in the cabinet body 1 to meet the needs of photovoltaic energy storage, emergency energy storage, etc. The energy storage module is existing technology, so it will not be described in detail.

[0032] This application also includes an inner structural frame 2, a lifting mechanism 3, a lateral translation mechanism 4, and a buffer balancer 5. The inner structural frame 2 can be a metal frame structure, and its outline can be an equidistant enlarged cabinet 1. The inner structural frame 2 is embedded in the building structure; for example, a suitable groove is cut into the wall, the inner structural frame 2 is embedded, and it is fixed with bolts. The inner wall of the groove can be smoothed with cement, coated with waterproof paint, and covered with a waterproof board to improve safety. One side of the inner structural frame 2 is provided as a structural opening, allowing the cabinet 1 to enter and exit, so that the cabinet 1 can be partially or completely placed within the inner structural frame 2; preferably, at least half of the cabinet 1 is included. This design, on the one hand, reduces the exposed space of the energy storage cabinet, thus minimizing its impact on indoor space; on the other hand, it provides support and protection for the energy storage cabinet, reducing the risk of it falling due to damage to the installation structure and increasing safety. The height of the inner structural frame 2 is preferably higher than that of the cabinet 1.

[0033] The lifting mechanism 3 includes guide rails 31, sliders 32, and linear drive units 33. Two guide rails 31 are vertically arranged, parallel to each other, and fixed to the inner structural frame 2 by screws. Two sliders 32 are slidably connected to the two guide rails 31. Each guide rail 31 has an anti-detachment structure to prevent the sliders 32 from tilting towards the structural opening of the inner structural frame 2. For example, the end of the guide rail 31 is T-shaped, using a lateral extension as an anti-detachment structure to prevent the sliders 32 from detaching. In this application, the anti-detachment structure of the guide rails 31 is necessary because the sliders 32 may tend to move outwards due to subsequent design changes. The linear drive unit 33 can be a servo motor and a screw mounted on the output shaft of the servo motor, with the screw threadedly connected to the sliders 32. Alternatively, the linear drive unit 33 can be a linear motor, with the driving direction of the linear motor parallel to the guide rails 31, meaning the sliding part of the linear motor is fixed to the sliders 32.

[0034] The lateral translation mechanism 4 is installed on the lifting part of the lifting mechanism 3, i.e., the aforementioned slider, and extends towards the structural opening. At least one connecting seat 6 is installed on the translation part of the lateral translation mechanism 4, and the upper part of the cabinet 1 is connected to the connecting seat 6.

[0035] The aforementioned buffer balancer 5 is used to delay the lifting and lowering of the cabinet 1 by gravity. The buffer balancer 5 is linked to the upper part of the cabinet 1 and the lifting part of the lifting mechanism 3.

[0036] As can be seen from the above, this application allows for the following: when it is necessary to operate the energy storage facility or maintain the energy storage structure, the horizontal translation mechanism 4 can be used to push it out from the inner structural frame 2, and then the lifting mechanism 3 can be used to move the cabinet 1 downwards, making it convenient for staff and users to access it.

[0037] The above setup allows the energy storage structure to be easily accessible to people even from a higher position, improving space utilization. Furthermore, since the cabinet 1 can be pulled back into the inner structural frame 2, it can further reduce space occupation, which is conducive to its promotion in small and medium-sized apartments and other places.

[0038] At the same time, the above-mentioned settings can also reduce the risk of cabinet 1 falling due to damage to the installation structure, and can protect it with the internal structural frame 2, which can effectively improve the safety of the energy storage structure.

[0039] In one embodiment of this application, a vertically arranged guide groove 11 is fixed to the side of the cabinet 1 facing the lifting mechanism 3 with countersunk screws. The lower part of the guide groove 11 and the side facing the lifting mechanism 3 are both open, and the opening facing the lifting mechanism 3 is folded inward. The aforementioned connecting seat 6 is slidably connected to the guide groove 11, that is, the cabinet 1 moves up and down relative to the connecting seat 6 and the lateral translation mechanism 4.

[0040] In this embodiment, the lateral translation mechanism 4 includes an inner beam plate 41, an outer beam plate 42 sleeved on the inner beam plate 41, and an electric cylinder 43. The inner beam plate 41 is fixed to the slider 32 with bolts, and the outer beam plate 42 is a hollow tube with one end fixed to the connecting seat 6 away from the slider 32. The electric cylinder 43 is installed on the slider 32 and its extension and retraction direction is parallel to the inner beam plate 41. The extension rod end of the electric cylinder 43 is fixed to the outer beam plate 42 or the connecting seat 6 through a bracket.

[0041] Based on the above configuration, the extension and retraction of the electric cylinder 43 can drive the cabinet 1 to move laterally, thereby propelling the cabinet 1 into and out of the inner structural frame 2. The sliding configuration of the guide groove 11 and the connecting seat 6 forms the basis of the buffer balancer 5, which will be explained later.

[0042] The buffer balancer 5 includes a counterweight 51, an intermediate spring 52, a fixed pulley 53, a top slide block 54, and a traction rope 55. In this embodiment, the weight of the counterweight 51 is designed to be 1 / 2 to 4 / 5 of the weight of the cabinet 1. The counterweight 51 can be a single piece, which is simultaneously slidably connected to two guide rails 31. The counterweight 51 is located below the slider 32.

[0043] Multiple intermediate springs 52 are arranged and fixed on the top of the counterweight 51, and the upper end of the intermediate spring 52 is fixed to the lower part of the slider 32.

[0044] Another track structure is fixed to the top of the inner structural frame 2. The top slide 54 is slidably connected to this track structure and its sliding direction is parallel to the lateral translation mechanism 4. A rotating shaft is fixed to the lower part of the top slide 54 by a bracket. The fixed pulley 53 is rotatably connected to the aforementioned fixed pulley 53 through the rotating shaft. The fixed pulley 53 is vertical and can be an I-beam pulley. One end of the traction rope 55 is tied and fixed to the upper part of the cabinet 1, and the other end passes over the fixed pulley 53 and is fixed to the upper middle position of the counterweight block 51.

[0045] According to the above settings, as the cabinet 1 is gradually pushed out of the inner structural frame 2 by the lateral translation mechanism 4, the traction rope 55 is pulled upward to initially lift the counterweight 51, and the intermediate spring 52 is initially compressed; after the cabinet 1 is separated from the inner structural frame 2, the cabinet 1 falls and continues to pull the counterweight 51 upward through the traction rope 55 and continues to compress the intermediate spring 52. During the process, due to the buffering effect generated by the compression of the intermediate spring 52 and the counterweight of the counterweight 51, the fall of the cabinet 1 is decelerated to a certain extent.

[0046] After the cabinet 1 has finished its natural descent phase, the slider 32 of the lifting mechanism 3 moves upward to release the intermediate spring 52. The counterweight 51 can then continue to move upward to compress the intermediate spring 52, thus enabling the cabinet 1 to continue descending. Moreover, the intermediate spring 52 acts as a buffer and delay throughout the entire process, making the descent of the cabinet 1 smoother.

[0047] When the cabinet 1 needs to be pulled upward, the slider of the lifting mechanism 3 moves downward to compress the intermediate spring 52, which in turn pushes the counterweight 51 to move downward. It is understandable that, in order to reduce damage to the intermediate spring 52, a limit rod can be fixed on the counterweight 51. After the limit rod contacts the slider 32, it can limit the amount of compression of the intermediate spring 52.

[0048] In another embodiment of that application, the application also includes a controller and a fall indicator unit 7. The controller can be a microcontroller, which can be encapsulated in a small box and installed in the inner structural frame 2. The controller is electrically connected to the linear drive unit 33 and the fall indicator unit 7. The fall indicator unit 7 includes a laser generator installed at the lower part of the cabinet 1 and / or an audible and visual alarm installed at the lower part of the cabinet 1. The laser emitting end of the laser generator is tilted downwards, and the tilt direction is the lower part closer to the lifting mechanism 3.

[0049] Example:

[0050] A laser generator (i.e., a device that can emit visible laser light) is embedded at the bottom outer position, and the laser is distributed horizontally in a fan shape; the controller is set to turn on the laser generator when the horizontal translation mechanism 4 moves, so as to project a laser pattern under the cabinet 1 in advance to alert the staff when the cabinet 1 gradually leaves the inner structural frame 2 and is about to fall, thereby improving the safety of use.

[0051] Understandably, the laser generator can be adjusted to project the final landing position of cabinet 1 from below when cabinet 1 has not completely detached from the inner structural frame 2, thereby improving the indication and reminder effect.

[0052] In another embodiment of this application, the controller is also electrically connected to a pressure sensor, which may be embedded in the bottom of the slider 32; a push plate is fixed to the upper part of the intermediate spring 52, and the push plate presses on the detection part of the pressure sensor, so that the reaction force generated by the intermediate spring 52 can be detected by the pressure sensor.

[0053] Based on the above, staff can configure the controller as follows:

[0054] 1) Set the upward movement trigger pressure threshold of slider 32. When the horizontal translation mechanism 4 pushes the cabinet 1 outward and the pressure detection value fed back by the pressure sensor reaches the upward movement trigger pressure threshold, the slider 32 is controlled to move upward, so that the cabinet 1 of this application has a higher degree of automation in lowering.

[0055] 2) Set the spring abnormal alarm pressure change rate. When the horizontal translation mechanism 4 pushes the cabinet 1 outward, calculate the change rate of the pressure detection value before the slider 32 moves upward. If the real-time change rate is greater than the spring abnormal alarm pressure change rate, it indicates that the intermediate spring 52 is damaged. At this time, a warning can be issued through the aforementioned audible and visual alarm, such as a flashing red light. This setting can prevent the intermediate spring 52 from being damaged without the user's knowledge, thus avoiding potential safety accidents.

[0056] Reference Figure 3 In another embodiment of this application, the cabinet 1 is provided with an auxiliary heat dissipation vent on the side facing the lifting mechanism 3, and a connector 8 is provided in the inner structural frame 2. The connector 8 is used to connect to an external heat sink or the inner structural frame 2 is a heat-conducting structure. An example of an external heat sink is a fan module. An example of an inner structural frame 2 being a heat-conducting structure is that it is made of heat-conducting metal material.

[0057] Furthermore, the outer end of the auxiliary heat dissipation vent is turned outward to form a protective edge to prevent condensate and other substances from directly entering the cabinet 1. The connector 8 includes a fixed head 81, a movable head 82 sleeved on the fixed head 81, and a return spring 83.

[0058] Among them, the fixed head 81 is a tube fixed to the inner structural frame 2. The tube is divided into two sections, front and back, with the diameter of the front section being smaller than that of the back section. The movable head 82 is another tube structure that is slidably connected to the fixed head 81. One end of the return spring 83 is fixed to the end of the thicker section of the fixed head 81, and the other end is fixed to the movable head 82.

[0059] As described above, the connector 8 is a telescopic structure, which can be inserted into the auxiliary heat dissipation port when the cabinet 1 is pulled into the inner structural frame 2, and good contact is ensured by the action of the return spring 83.

[0060] In another embodiment of this application, a roller 12 is embedded inside the cabinet 1. The wheel surface of the roller 12 protrudes from the lower surface of the cabinet 1 by 1-3 cm; otherwise, the cabinet 1 is prone to collision damage during the process of sliding out of the inner structural frame 2. At the same time, a composite board 9 is installed at the bottom of the inner structural frame 2. The composite board includes a stacked panel and an elastic board, with the panel located above the elastic board. The elastic board can be a rubber board or a sponge board to provide vibration cushioning and further reduce the probability of damage to the cabinet 1.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
