Description

Technical Field

[0001] This utility model relates to the field of power battery technology, and in particular to a power battery box with a heat-insulating inner lining. Background Technology

[0002] As the core energy component of new energy vehicles, energy storage power stations, and various portable devices, the safety and stability of power batteries are of paramount importance. The power battery housing is a key structure specifically designed to support, fix, and protect the power battery pack.

[0003] In practical applications, power battery boxes not only need to provide physical protection for the batteries to resist external impacts and vibrations, but also need to provide a suitable working environment, such as maintaining a stable working temperature through heat-insulating linings. More importantly, they must reliably limit and fix the internal power batteries. However, there are many specifications of power batteries on the market. Power batteries from different manufacturers, batches, and even application scenarios have differences in external dimensions. When designing many existing power battery boxes, their internal fixing structures are usually customized for a specific type of battery, such as using fixed-size slots, partitions, or pre-formed buffer pads.

[0004] This fixed-size design results in extremely poor versatility. When it is necessary to replace the power battery with a different size, the original fixed structure cannot provide effective clamping and limiting. Gaps will be generated in the battery inside the box. During equipment operation or vehicle travel, unavoidable bumps and vibrations will cause the battery to shake and collide inside the box. This can not only easily damage the battery itself or its connection lines, but may also cause serious safety hazards.

[0005] Therefore, this utility model proposes a power battery box with a heat-insulating inner lining to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the existing technology of power battery boxes with heat insulation lining, such as the single internal fixing structure size, incompatibility with power batteries of different specifications, resulting in unstable fixing and easy shaking, this utility model aims to provide a power battery box with heat insulation lining with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a power battery box with a heat-insulating inner lining, including a box, a first fixing plate and a second fixing plate that are fixedly connected to the inner wall of the box perpendicularly to each other, and a first adjusting plate that is slidably connected to the second fixing plate, and a second adjusting plate that is slidably connected to the first fixing plate.

[0008] The housing also includes a first fixing mechanism and a second fixing mechanism. The first fixing mechanism is used to lock the first adjusting plate and the second fixing plate. The first fixing mechanism includes an extension rod, a push block fixedly connected to the extension rod, a first spring sleeved on one end of the push block, a first locking block fixed to the push block, and a baffle fixed inside the first adjusting plate.

[0009] Furthermore, the two ends of the first spring abut against the baffle and the push block respectively, and a movable slot for the first locking block to pass through is provided on the second fixed plate. A slot for the locking block of the second fixing mechanism to be engaged is also provided on the first adjusting plate. The second fixing mechanism is used to lock the second adjusting plate on the first adjusting plate.

[0010] Preferably, the second fixing mechanism is disposed on the second adjusting plate, and includes a fixing block, a second locking block, a second spring, and a handle fixedly connected to the second locking block, which are fixedly installed on the second adjusting plate. The fixing block has a fixed track inside for the second locking block to slide, and the second spring is housed in the fixed track and abuts against the second locking block.

[0011] Preferably, the second fixed plate has a first guide groove extending along its length, and the first adjusting plate is slidably connected to the first guide groove by a slider provided thereon, so as to ensure the stability of the sliding adjustment.

[0012] Preferably, the first fixed plate has a second guide groove extending along its length, and the second adjusting plate is slidably connected to the second guide groove by a slider provided thereon, so as to achieve precise longitudinal guidance.

[0013] Preferably, the bottom of the box is detachably covered with a heat insulation pad, and the accommodating space formed by the first fixing plate, the second fixing plate, the first adjusting plate and the second adjusting plate is located above the heat insulation pad to provide heat insulation and cushioning.

[0014] Preferably, the box has multiple heat dissipation holes on at least one side wall, which penetrate the side wall of the box, so that the inside of the box is connected to the external environment, which facilitates heat dissipation.

[0015] Preferably, one end of the extension rod of the first fixing mechanism passes through the wall of the first adjusting plate and is exposed to the outside for easy operation. The first locking block passes through the movable slot and is locked into the first adjusting plate under the elastic force of the first spring, thereby achieving automatic locking.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that the internal size of the power battery box is uniform and cannot be compatible with batteries of different specifications, resulting in unstable fixation, by setting a first adjustment plate and a second adjustment plate that can slide in both the horizontal and vertical directions, so that together with the fixed plate they can form a variable-sized accommodating space. This achieves the technical effect of being able to flexibly adapt to and securely fix power batteries of various sizes, thereby improving the versatility and applicability of the device.

[0017] 2. This utility model solves the problems of cumbersome adjustment process, time-consuming locking, and potential need for tools in the prior art by equipping the sliding adjustment plate with a spring-driven reset locking mechanism. It achieves the technical effect of simple adjustment and positioning operation, quick locking and fixing without additional tools, and improved battery installation and replacement efficiency.

[0018] 3. This utility model solves the problem of the existing technology having a single thermal management measure that cannot effectively isolate external environmental heat and dissipate internal battery heat at the same time by setting a heat insulation inner lining at the bottom of the box and opening heat dissipation holes on the side wall of the box. It achieves the technical effect of providing dual protection for the power battery with heat insulation and heat dissipation, ensuring its safe and efficient operation in a more stable temperature environment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 5 This utility model provides a power battery box with a heat-insulating inner lining, which aims to solve the problem that the internal fixing structure of the power battery box in the prior art has a single size and cannot be compatible with power batteries of different specifications, resulting in unstable fixing.

[0023] like Figure 1 As shown, the power battery box with a heat-insulating inner lining includes a box 1. A heat-insulating pad 3 is detachably laid on the bottom of the box 1. At least one heat dissipation hole 2 is opened on the side wall of the box 1. The box 1 is equipped with a first fixing plate 4, a second fixing plate 5, a first adjusting plate 6, and a second adjusting plate 7. The first fixing plate 4 and the second fixing plate 5 are fixedly connected to the inner wall of the box 1 perpendicularly to each other. The first adjusting plate 6 is slidably connected to the second fixing plate 5, and the second adjusting plate 7 is slidably connected to the first fixing plate 4. These four together enclose a rectangular space with adjustable size for accommodating the power battery. This space is located above the heat-insulating pad 3.

[0024] To ensure reliable locking of the adjusted plates, the housing also includes a first fixing mechanism 8 and a second fixing mechanism 9. The first fixing mechanism 8 is mounted on the first adjusting plate 6 and is used to lock the first adjusting plate 6 to the second fixing plate 5. The second fixing mechanism 9 is mounted on the second adjusting plate 7 and is used to lock the second adjusting plate 7 to the first adjusting plate 6. Figure 2 , Figure 3 and Figure 4 The first fixing mechanism 8 includes a baffle 801, a first spring 802, a push block 803, a first locking block 804, and an extension rod 805. The baffle 801 is fixed in the internal cavity of the first adjusting plate 6. The push block 803 is movably disposed in the internal cavity. The first spring 802 is sleeved on one end of the push block 803, and the two ends of the first spring 802 elastically abut against the baffle 801 and the push block 803, respectively. The first locking block 804 is fixedly connected to the push block 803. One end of the extension rod 805 is fixedly connected to the push block 803, and the other end passes through the wall of the first adjusting plate 6 and is exposed to the outside, cooperating with the first fixing mechanism 8. The second fixing plate 5 is provided with a movable slot 806 for the first locking block 804 to be inserted or disengaged. At the same time, in order to realize the locking of the second fixing mechanism 9, the first adjusting plate 6 is also provided with a slot for the locking block of the second fixing mechanism 9 to be engaged.

[0025] To achieve the adaptive fixing of power batteries of different sizes, the core of the technical solution in this embodiment lies in forming a limiting frame that can be adjusted bidirectionally and locked quickly through the sliding cooperation of the first adjusting plate 6 and the second adjusting plate 7 and the locking cooperation of the first fixing mechanism 8 and the second fixing mechanism 9. The core structure and its cooperation relationship for realizing this solution will be described in detail below.

[0026] Please refer to the following carefully. Figure 2 , Figure 4 and Figure 5 In order to achieve stable sliding of the first adjusting plate 6 and the second adjusting plate 7, a first guide groove extending along its length is provided on the second fixed plate 5. The first adjusting plate 6 is slidably connected to the first guide groove by a slider provided on it, ensuring the smoothness and stability of the first adjusting plate 6 during the lateral adjustment process. Similarly, a second guide groove extending along its length is also provided on the first fixed plate 4. The second adjusting plate 7 is slidably connected to the second guide groove by a slider provided on it, ensuring the precise guidance of the second adjusting plate 7 during the longitudinal adjustment process.

[0027] Please refer to the following carefully. Figure 2 and Figure 4 The structure of the second fixing mechanism 9 is described in detail. The second fixing mechanism 9 is fixedly installed on the second adjusting plate 7. It includes a fixing block 901. The fixing block 901 has a fixing track 903 inside for limiting the movement trajectory. The second locking block 904 is movably accommodated in the fixing track 903 and can slide back and forth in the length direction of the fixing track 903. The second spring 902 is also accommodated in the fixing track 903. The second spring 902 is a compression spring. One end of the spring abuts against the inner side wall of the fixing track 903, and the other end abuts against the second locking block 904. The second fixing mechanism 9 includes a handle 905, one end of which is fixedly connected to the second locking block 904, and the other end of which passes through the wall of the fixing block 901 and is exposed to the outside, so as to facilitate the user to pull. When locking is required, the handle 905 is released, and the second spring 902 pushes the second locking block 904 to automatically lock into the preset slot on the first adjusting plate 6. This spring-driven locking structure realizes fast and reliable longitudinal locking.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, in order to enhance the heat insulation protection effect of the housing for the power battery and provide cushioning, a heat insulation pad 3 is detachably laid on the bottom of the housing 1. The heat insulation pad 3 can be made of a material with good heat insulation and shock absorption performance, such as foam rubber or aerogel felt. The battery housing space formed by the first fixing plate 4, the second fixing plate 5, the first adjusting plate 6 and the second adjusting plate 7 is located directly above the heat insulation pad 3.

[0029] As another preferred embodiment, in order to dissipate the heat generated by the power battery during operation in a timely manner and maintain a suitable working temperature inside the box, a number of heat dissipation holes 2 are provided on the side wall of the box 1. These heat dissipation holes 2 penetrate the side wall of the box 1, so that the internal space of the box 1 is connected to the external environment, thereby forming an air convection path.

[0030] As another preferred embodiment, in order to make the sliding adjustment process of the first adjusting plate 6 and the second adjusting plate 7 more stable and precise, the second fixed plate 5 is provided with a first guide groove extending along its length direction. The first adjusting plate 6 is slidably connected to the first guide groove by a slider provided thereon. Similarly, the first fixed plate 4 is also provided with a second guide groove extending along its length direction. The second adjusting plate 7 is slidably connected to the second guide groove by a slider provided thereon. This guide rail and slider cooperation structure can effectively prevent the adjusting plate from shifting or getting stuck during the movement.

[0031] As a preferred design for the first fixing mechanism 8, in order to facilitate user operation and achieve quick unlocking, one end of the extension rod 805 passes through the wall of the first adjusting plate 6 and is exposed to the outside. The user can directly pull the extension rod 805. When the external force is released, the first locking block 804 can automatically pass through the movable slot 806 and lock into the interior of the first adjusting plate 6 under the elastic potential energy of the first spring 802, thereby completing the locking action.

[0032] As a specific structural implementation of the second fixing mechanism 9, the fixing block 901 is fixedly installed on the outer surface of the second adjusting plate 7. The fixing track 903 inside provides a clear sliding path for the second locking block 904. The second spring 902 is housed in the fixing track 903 and continuously applies abutting force to the second locking block 904, ensuring the immediacy and reliability of locking.

[0033] Working principle: When this device is needed to accommodate and fix the power battery, firstly, the heat insulation pad 3 is laid on the bottom of the box 1, and then the power battery is placed on top of the heat insulation pad 3. At this time, the power battery is located in the initial space formed by the first fixing plate 4, the second fixing plate 5, the first adjusting plate 6 and the second adjusting plate 7. Then, the lateral dimension is adjusted. The operator slides the first adjusting plate 6 along the guide groove on the second fixed plate 5, so that it gradually approaches and finally fits tightly against the side of the power battery. After the adjustment is in place, the operator releases or pushes the extension rod 805 in the opposite direction. After the external force is lost, the compressed first spring 802 releases its elastic potential energy, pushing the push block 803 and the first locking block 804 connected to it to reset. The first locking block 804 passes through the movable slot 806 on the second fixed plate 5 and finally locks into the interior of the first adjusting plate 6, thereby achieving a reliable lock between the first adjusting plate 6 and the second fixed plate 5. Next, the longitudinal dimension is adjusted. The operator slides the second adjusting plate 7 along the guide groove on the first fixed plate 4, so that it is close to the other side of the power battery. When the adjustment is in the right position, the operator releases the handle 905. Under the pushing action of the second spring 902, the second locking block 904 slides along the fixed track 903 and automatically locks into the preset slot on the first adjusting plate 6, thus locking the second adjusting plate 7 and the first adjusting plate 6. Thus, through the dual adjustment and locking of the horizontal and vertical dimensions, the power battery is firmly limited in the box to prevent it from shaking. During the operation of the battery, the heat generated can be dissipated to the external environment through the heat dissipation holes 2 on the side wall of the box 1.
