[0038] The core of this application is to provide a module shell to improve the energy density of the module shell.

[0039] Another core of the present application is to provide a battery energy storage system having the above-mentioned module housing.

[0040] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] As described in the background art, the module housing in the prior art requires an additional handle, and the handle is usually an embedded buckle or internally hidden handle, so that the handle structure will occupy the space inside the module housing, thereby reducing the energy density of the battery. For this reason, this application provides a module housing, and when the module housing needs to be transported, the handle and the module housing can be quickly installed, and when the module housing does not need to be transported, the handle and the module housing can be quickly disassembled. This reduces the problem of low module housing energy density caused by the additional space for the handle.

[0042] In order to achieve the above purpose, this application is combined with the attached Figures 1 to 12Detailed introduction to the structure of the module shell:

[0043] See also Figures 1 to 5 The module shell includes a module shell 100 and a handle 200, wherein: the module shell 100 is provided with at least one set of fixing parts 110, the fixing part 110 includes a blocking part 111, a connecting part 112 and a fixing part 113, the connecting part 112 connects the blocking part 111 and the fixing part 113, and a clamping notch is formed between the blocking part 111 and the fixing part 113, and the outer diameter of the connecting part 112 is smaller than the outer diameter of the blocking part 111; the handle 200 is provided with a clamping part 210, the clamping part 210 includes a sleeve hole 211 that can be sleeved on the outer periphery of the blocking part 111 and a clamping hole 212 that penetrates the sleeve hole 211, the aperture D2 of the sleeve hole 211 is larger than the outer diameter d2 of the blocking part 111; the aperture D1 of the clamping hole 212 is larger than the outer diameter d1 of the connecting part 112 and smaller than the outer diameter d2 of the blocking part 111, so as to form a gourd hole structure, such as Figure 6 shown.

[0044] When carrying the module housing, in order to make the sleeve hole 211 of the clamping member 210 sleeved on the outer periphery of the blocking portion 111, the clamping member 210 can be slid so that the clamping hole 212 is located at the clamping notch, and the blocking portion 111 of the fixing member 110 is shoveled up, as shown in FIG. Figure 6 As shown, a transition zone 213 is formed at the intersection of the sleeve hole 211 and the clamping hole 212, and the transition zone 213 is thinned so that the thickness of the transition zone 213 is smaller than the hole eaves thickness of the sleeve hole 211 and the hole eaves thickness of the clamping hole 212.

[0045] When the module housing in the above example of the present application is used, only when the module housing is transported, the sleeve hole 211 of the clamping member 210 can be sleeved on the outer periphery of the blocking portion 111, such as Figure 7 As shown in FIG. 2 (a), the sliding clamping member 210 makes the clamping hole 212 located at the clamping notch. Figure 7 As shown in Figure (b) in the figure. Because the aperture D1 of the latch hole 212 is larger than the outer diameter d1 of the connecting portion 112 and smaller than the outer diameter d2 of the blocking portion 111, the module housing can be transported by lifting the handle 200. When the module housing is transported to the appropriate position, the latching member 210 is slid in the opposite direction, the latching hole 212 is disengaged from the engaging notch, and the sleeve hole 211 can be disengaged from the latching member 210 through the blocking portion 111 without affecting the normal arrangement of the module housing. It can be seen that the provision of the handle 200 in the module housing of the present application occupies less space in the module housing 100, thereby improving the energy density of the module housing.

[0046] It should be noted that when the module housing of the present invention is not equipped with the handle 200, Figure 1 and Figure 2As shown, the module housing 100 has a top cover 120, a side cover, and a bottom cover 140, wherein the top cover 120 and the bottom cover 140 are arranged oppositely at both ends of the side cover to close the side cover, forming the module housing 100 of the module shell. The first plug-in terminal 150 of the module shell is provided on the top cover 120, and the second plug-in terminal 160 is provided on the bottom cover 140. The first plug-in terminal 150 and the second plug-in terminal 160 correspond in size and position. In this way, when the module shells are stacked, the second plug-in terminal 160 of the module shell at the top is plugged into and matched with the first plug-in terminal 150 of the module shell at the bottom to achieve electrical connection.

[0047] The fixing member 110 can be arranged on the top cover 120 of the module housing 100, such as Figure 3 or the fixing member 110 may be arranged on the side panel 130 of the module housing 100, as shown; Figure 4 The following examples of this application only introduce the way in which the fixing member 110 is arranged on the top cover 120, and the way in which the fixing member 110 is located on the side plate 130 can be used as a reference and will not be repeated here.

[0048] In order to reduce the impact of the fixing member 110 on the airtightness of the module housing 100, the module shell further includes a connecting member 170, which is connected to the module housing 100 (top cover 120) as a whole and isolated from the interior of the module housing 100; the fixing portion 113 is limited to the connecting member 170.

[0049] In one example, the connector 170 is a pressure-welded nut, which is welded to the top cover 120 of the module housing 100 to form a whole, thereby ensuring the sealing performance between the pressure-welded nut and the module housing 100 .

[0050] The aforementioned positioning of the fixing portion 113 on the connecting member 170 can be understood as ensuring a stable connection between the fixing portion 113 and the fixing member 110, i.e., enabling the module housing to be lifted using the handle 200 after connection. In one example, the fixing portion 113 and the connecting member 170 are threadedly connected. Specifically, the connecting member 170 has internal threads, and the outer periphery of the fixing portion 113 has external threads that mate with the internal threads. The fixing portion 113 can be connected to the connecting member 170 by rotation, thereby facilitating disassembly and adjusting the height between the fixing portion 113 and the connecting member 170.

[0051] To enhance the connection strength between the fixing portion 113 and the connector 170, a stop washer 114 is provided on one end of the fixing portion 113 near the connector 112. When the stop washer 114 abuts the top cover 120, the fixing portion 110 is securely installed. Stopping the rotation completes the installation of the fixing portion 110 and the module housing 100.

[0052] In one example, the fixing portion 113 and the connecting member 170 are movably connected, and the connecting member 170 may further include a limit block 171. At the same time, the connecting member 170 is formed with a cavity for installing the fixing portion 113, so that the fixing portion 113 can be located in the cavity, and the fixing portion 113 and the connecting member 170 are slidably matched. At the same time, a limit block 115 is provided at one end of the fixing portion 113 away from the connecting portion 112, and the outer diameter of the limit block 115 is larger than the inner diameter of the limit block 171. Figure 8 shown.

[0053] When the module housing needs to be carried, the fixing member 110 is lifted to a certain height, the sleeve hole 211 is sleeved on the outer periphery of the blocking portion 111, and the sliding clamping member 210 is slid so that the clamping hole 212 is located at the clamping notch. Figure 9 Because the diameter D1 of the locking hole 212 is larger than the outer diameter d1 of the connecting portion 112 and smaller than the outer diameter d2 of the blocking portion 111, the module housing can be transported by simply pulling the handle 200. When the module housing is transported to a suitable location, the locking member 210 is slid in the opposite direction, the locking hole 212 is disengaged from the locking notch, and the sleeve hole 211 can be disengaged from the locking member 210 through the blocking portion 111 without affecting the normal arrangement of the module housing.

[0054] It should be noted here that the thickness of the edges of the connecting portion 112 and the blocking portion 111 can gradually become thicker (it can also be understood that the thickness gradually changes from the edge of the blocking portion 111 to the edge of the connecting portion 112). In this way, when the sleeve hole 211 is sleeved on the outer periphery of the blocking portion 111, the fixing member 110 is lifted to a certain height with the help of the clamping member 210, so that when the clamping member 210 is slid, the clamping hole 212 is directly clamped in the medium clamping notch.

[0055] Alternatively, a step portion 116 is provided in the area between the blocking portion 111 and the connecting portion 112. When the handle 200 is not installed, a transition notch 118 is provided between the step portion 116 and the limit block 171. The transition notch 118 can provide a force point for the clip 210, that is, the clip 210 contacts the hole wall of the sleeve hole 211 during the sliding process.

[0056] In some examples of this application, to optimize the structure of the module housing, a reset member 117 is further provided between the fixing portion 113 and the connector 170. When the handle 200 is not installed, the majority of the fixing member 110 retracts into the connector 170, thereby reducing the impact of the fixing member 110 on the size of the module housing 100. In this case, the reset member 117 can provide a push or pull force to the fixing portion 113. Any structure that can keep the majority of the fixing member 110 within the connector 170 under the action of the reset member 117 is within the scope of protection of this application.

[0057] In some examples, one end of the reset member 117 is connected to the fixing portion 113, and the other end of the reset member 117 is connected to the connecting member 170, and when the reset member 117 is in a natural state, the connecting portion 112 contacts the limit stopper 171. The reset member 117 is placed between the fixing member 110 and the connecting member 170 in a natural state, and the blocking portion 111 abuts against the limit stopper 171 without external force. Figure 8 When the handle 200 is mounted on the fixing member 110, the above process needs to overcome the pulling force of the reset member 117 and complete the engagement of the clamping hole 212 with the clamping notch, as shown in FIG. Figure 9 As shown, the reset member 117 is in a stretched state. Since the limit block 115 is in contact with the limit stopper 171, the module housing can be smoothly lifted by the handle 200. When the handle 200 is removed, the fixing member 110 is reset under the action of the reset member 117.

[0058] The above mainly introduces the connection between the fixing member 110 and the module housing 100. In some examples of this application, the structure of the handle 200 is also improved.

[0059] like Figures 10 to 12 As shown, the illustrated handle 200 includes a grip portion 220, which can be integrally formed or separated from a clip 210. The grip portion 220 includes at least one crossbeam 221 and connecting beams 222 connected at both ends of the crossbeam 221, with a gripping space formed between the connecting beams 222 and the crossbeam 221. The clip 210 is located at the end of the connecting beam 222, and the connecting beam 222 and the clip 210 can be integrally formed or separated.

[0060] The above-mentioned beam 221 can be understood as the hand-holding part of the handle 200. The beam 221 can be one or more. In the figure, there are two beams 221, one of which can be understood as the main hand-holding part, and the other beam 221 is arranged to achieve the purpose of improving the overall strength of the handle 200.

[0061] In order to improve the physical comfort of holding and reduce fatigue, the crossbeam 221 serving as the hand-held portion can be thickened, for example, by providing a wrapping software, which can be made of foam or rubber material.

[0062] The connecting beam 222 and the clamping member 210 may be an integrated structure, such as Figure 10 and Figure 11 As shown, in order to ensure the reasonableness of the force applied to the handbag, the connecting beam 222 and the clip 210 can be arranged at a preset angle. Figure 10 The handle 200 shown is mainly installed at the top cover 120 of the module housing 100, and the angle between the connecting beam 222 and the clamping member 210 is between 90° and 180°; Figure 11The illustrated handle 200 is primarily mounted on the side panel 130 of the module housing 100, with the connecting beam 222 and the clip 210 positioned at an angle between 180° and 270°. These angles can be adjusted based on actual needs, and will not be further detailed here. As can be seen from the above example, the integrated structure of the connecting beam 222 and the clip 210 enhances the overall strength and stability of the handle 200, preventing breakage at the connection between the connecting beam 222 and the clip 210 when the handle 200 is pulled.

[0063] The connecting beam 222 and the clamping member 210 may also be a split structure. In this case, the two are fixed to each other. Except for the split design, other positions can refer to the relevant description of the integrated structure.

[0064] Alternatively, the connecting beam 222 and the clamping member 210 may be rotatably connected. Figure 12 As shown, the connecting beam 222 and the clamping member 210 are connected by a hinge 230. Therefore, the angle between the connecting beam 222 and the clamping member 210 is adjustable, and the angle between the connecting beam 222 and the clamping member 210 can be adjusted arbitrarily according to actual needs.

[0065] It should be noted that, generally, one module housing 100 corresponds to two handles 200, and the two handles 200 are symmetrically arranged on the module housing 100. One handle 200 can be provided with one clip 210, or one handle 200 can be provided with two clips 210. The figure includes two crossbeams 221, two connecting beams 222 and two clips 210. The two crossbeams 221 are arranged in parallel, and the two connecting beams 222 are arranged at the two ends of the two crossbeams 221. A clip 210 is provided at the end of each of the two connecting beams 222. The connection relationship between the connecting beams 222 and the clips 210 can be referred to above. Figures 10 to 12 Description.

[0066] The module housing described above has the following beneficial effects: It reduces the cost of the handle 200 on the module housing 100, reduces the space occupied by the handle 200, and reduces sealing risks associated with the handle 200; it also improves the energy density of the module housing, making the module integration more efficient. Furthermore, the handle 200 can be freely adjusted at multiple angles, making it easier to find the most suitable angle during lifting. The handle 200 of this application avoids the risk of operation without the presence of installation and maintenance professionals, and also prevents product loss or theft.

[0067] The present application also provides a battery energy storage system including any of the above module housings. Since the above module housing has the above beneficial effects, the battery energy storage system including the module housing has corresponding effects, which will not be described in detail here.

[0068] The module housings may include at least two, and the module housings are stacked. In this case, the fixing member 110 can play a positioning role in the stacking position of the two adjacent module housings. Specifically, when the fixing member 110 is set at the top of the module housing, a positioning hole that cooperates with the blocking portion 111 of the fixing member 110 can be set at the bottom of the module housing. When the module housing is placed, the positioning hole at the bottom of the module housing can be aligned with the blocking portion 111 of the fixing member 110 at the top of the adjacent module housing, so that the blocking portion 111 is inserted into the positioning hole. This allows the positioning hole to limit the blocking portion 111, thereby preventing the positions of the adjacent module housings from shifting when stacked.

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