Description

Technical Field

[0001] This article belongs to the field of energy storage battery technology, specifically involving an easy-pull energy storage battery box with ball bearing guide rail groove, which is suitable for containerized energy storage systems, industrial and commercial energy storage cabinets and other scenarios. Background Technology

[0002] In the rapidly developing field of containerized energy storage systems and commercial and industrial energy storage cabinets, battery packaging boxes bear the core function of ensuring the efficient, safe, and reliable operation of the system. Their importance is reflected in several aspects: as the physical carrier and protective shell of the energy storage battery modules, the packaging box is directly related to the integration density, structural stability, and ability to resist environmental damage of the battery clusters in a limited space. More importantly, its design characteristics profoundly affect the maintainability and operation and maintenance efficiency of the system. In large-scale energy storage projects, battery clusters are often densely arranged in cabinets or containers several meters high. Daily inspections, fault location, module replacement, and other maintenance operations are frequent and necessary. At this time, the operability of the packaging box, especially its ease of pushing and pulling, becomes a key factor in determining the operation and maintenance efficiency and operational safety.

[0003] However, the traditional packaging boxes based on the support slide rail structure, which are currently widely used, have revealed significant inconveniences and risks in practical applications, mainly in two aspects:

[0004] The operation is extremely laborious and dangerous: Due to the huge weight of the battery packaging box, usually exceeding 150 kg, and the fact that the box and the support rely only on the sliding friction contact of rigid structural components, the pushing and pulling resistance during maintenance and disassembly is extremely large. This not only requires multiple people to work together to complete simple extraction and pushing operations, consuming a lot of manpower, but also brings extremely high operational risks when working at high positions on the battery cluster. Personnel pushing and pulling heavy objects at high positions are very likely to lose their balance or cause muscle injuries, or even cause safety accidents.

[0005] Easy jamming affects reliability and emergency response: Traditional load-bearing slide rail structures have inherent defects, easily accumulating dust and impurities. During long-term use, the intense sliding friction between the housing and the slide rail will inevitably wear down or even damage the protective coating on the slide rail surface, causing the metal substrate to be exposed and rusted. Rust and dirt accumulation will significantly increase frictional resistance, causing jamming and jerking during the pushing and pulling of the housing. In severe cases, it may even lock completely. This not only greatly increases the difficulty and time consumption of daily maintenance, but also constitutes a serious obstacle in emergency situations, making it impossible to guarantee timely and reliable opening and maintenance, creating safety hazards, and becoming an operational bottleneck that restricts the availability and security of the system. Utility Model Content

[0006] To address some of the technical challenges mentioned above, this paper proposes an innovative battery packaging box design. This design aims to systematically solve a series of key challenges in battery pack safety during installation and performance optimization during use.

[0007] A push-pull type energy storage battery box with ball bearing guide rail groove includes an energy storage compartment, a cluster rack, a battery packaging box, a cooling fan, a heat dissipation hole, a box handle, an indicator light, a ball bearing guide rail, a linear slide rail, and a battery pack.

[0008] The energy storage compartment is equipped with horizontally extending cluster racks, which divide the energy storage compartment into multiple installation spaces.

[0009] The battery packaging box is set in the installation space. An indicator light is provided on the upper part of the front side wall, a cooling fan is provided on the lower part of the front side wall, handles are provided on the left and right sides of the front side wall, ventilation holes are provided on the left and right sides, the battery pack is provided inside, and a linear slide rail is fixed at the bottom.

[0010] The cluster frame is equipped with ball bearing guides, and bolt holes are provided on the mounting surface of the ball bearing guides. The ball bearing guides are fixed to the cluster frame by bolts.

[0011] The linear slide rail at the bottom of the battery packaging box is slidably connected to the ball bearing guide rail on the cluster frame. The ball bearing guide rail has a raceway inside that accommodates multiple precision balls. The precision balls of the ball bearing guide rail are evenly fixed by a retainer to form a continuous rolling contact surface, which allows the battery packaging box to slide smoothly on the guide rail of the cluster frame and greatly reduces frictional resistance.

[0012] The precision balls of the ball guide are evenly fixed by the cage to form a continuous rolling contact surface.

[0013] The ball bearing guide rail is provided with positioning holes at intervals along its length. The bottom of the battery packaging box is provided with a locking pin, which corresponds to the position of the positioning hole. The locking pin is provided with a manual operating lever, which drives the locking pin to move vertically through a transmission link. When the battery packaging box slides to the predetermined position, the locking mechanism is operated to insert the locking pin into the positioning hole, thereby achieving a stable lock and preventing the battery packaging box from moving accidentally during transportation or use, thus improving the overall safety and reliability of the system.

[0014] The linear guide rail has a buffer pad at the end, and the battery packaging box has a buffer pad at the rear end. The buffer pads are made of silicone. This buffer design effectively absorbs the impact force when the battery packaging box is pushed into place, protecting the structure and internal battery module from damage.

[0015] The ratio of ball diameter to guide rail groove clearance is 1:0.8. This mechanically optimized design ensures smooth rolling and prevents ball slippage, significantly reducing the moving resistance of the battery packaging box and making installation, replacement and maintenance easier and faster. At the same time, the rolling contact surface reduces friction and wear.

[0016] The ball assembly is located inside the ball guide rail. The ball assembly adopts a modular design. Each ball assembly module includes a cage, balls and a mounting base. The mounting base is fixed inside the ball guide rail by a detachable connector. This modular quick-release structure allows each ball assembly module to be replaced independently, significantly shortening maintenance time.

[0017] Beneficial effects:

[0018] Based on the above innovative design, this product achieves a significant improvement in overall performance. Its continuous rolling contact surface, composed of ball bearing guides and linear slides, greatly reduces frictional resistance, allowing for easy single-person push-pull operation of the heavy-duty battery box, thus improving installation efficiency. Simultaneously, the silicone buffer pads at the ends of the guides effectively eliminate impact upon placement. A millimeter-level mechanical locking mechanism using positioning pins and holes completely prevents accidental displacement during transportation and operation, ensuring electrical connection stability and system safety. Modular ball bearing assemblies support quick replacement, significantly reducing maintenance costs and preventing the scrapping of the entire rail due to localized damage. The synergistic design of the heat dissipation system and impact-resistant structure extends battery life. Multi-layered clusters and standardized guide rail interfaces further enhance the flexible expansion capabilities and equipment compatibility of the energy storage system. Therefore, it systematically addresses the core pain points of battery deployment and maintenance in four dimensions: installation efficiency, operational safety, total lifecycle cost, and expansion flexibility.

Detailed Implementation

These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0028] Energy storage compartment 1, cluster rack 101, battery packaging box 2, cooling fan 201, heat dissipation hole 202, box handle 203, indicator light 204, linear slide rail 205, ball bearing guide rail 206, battery pack 207.

[0029] like Figure 1 , 2 As shown in 3, 4, 5, 6, and 7

[0030] A push-pull type energy storage battery box 2 with ball bearing guide rail groove includes an energy storage compartment 1, a cluster frame 101, a battery packaging box 2, a cooling fan 201, heat dissipation holes 202, a box handle 203, an indicator light 204, a ball bearing guide rail 206, a linear slide rail 205, and a battery pack 207. The energy storage compartment 1 has a horizontally extending cluster frame 101 inside, which divides the energy storage compartment 1 into multiple installation spaces. The battery packaging box 2 is installed within these installation spaces. An indicator light 204 is located on the upper part of the front side wall of the battery packaging box 2, a cooling fan 201 is located on the lower part of the front side wall, a box handle 203 is located on the left and right sides of the front side wall, and heat dissipation holes 202 are located on the left and right sides of the front side wall. The battery pack 207 is installed inside the box, and a linear slide rail 205 is fixedly installed at the bottom. A ball bearing guide rail 206 is installed on the cluster frame 101, and bolt holes are provided on the mounting surface of the ball bearing guide rail 206, which is fixed to the cluster frame 101 with bolts. 1. The battery packaging box 2 has an internal raceway for accommodating multiple precision balls. The ball assembly is located within this raceway. The linear slide rail 205 at the bottom of the battery packaging box 2 is slidably connected to the ball guide rail 206 on the cluster frame 101. The precision balls inside the ball guide rail 206 are uniformly fixed by a retainer to form a continuous rolling contact surface. The ball guide rail 206 has positioning holes spaced along its length. The bottom of the battery packaging box 2 has locking pins corresponding to the positions of the positioning holes. The locking pins have manual operating levers and are driven by a transmission linkage to achieve vertical movement. The ends of the linear slide rail 205 and the rear end of the battery packaging box 2 are equipped with buffer pads, and these buffer pads are made of silicone. The ratio of the ball diameter to the guide rail groove clearance of the ball guide rail 206 is 1:0.8. The ball assembly adopts a modular design. Each ball assembly module includes a retainer, balls, and a mounting base. The mounting base is fixed inside the ball guide rail 206 by a detachable connector.

[0031] Implementation Example

[0032] The installation of the battery packaging box 2 begins with the pre-fixing of the guide rail of the energy storage compartment 1 cluster rack 101. The ball bearing guide rail 206 is precisely installed in the preset position of the cluster rack 101 by bolts. Then, the operator holds the handles on both sides of the box and gently pushes the bottom linear slide rail 205 into the guide slope of the ball bearing guide rail 206. When the silicone buffer pad at the rear of the box contacts the buffer pad at the end of the guide rail and produces a slight compression deformation, the box reaches the working position. At this time, the manual operating lever is pulled to drive the locking pin to be vertically inserted into the positioning hole to complete the mechanical locking. No tools are required throughout the process. During routine maintenance, if the ball bearing module needs to be replaced, only the single-point detachable connector needs to be removed to pull out the faulty module. The replacement can be completed and the operation restored within 5 minutes.

[0033] The experimental testing method for this product is as follows: after 500 consecutive push-pull cycles at a high temperature of 45℃, the temperature rise of the guide rail groove is stably controlled within 8℃ without any jamming. At the same time, through a simulated earthquake shaking table test at a vibration frequency of 5Hz, the box structure shows no deformation and the ball bearing assembly remains stable, proving its operational reliability under high load and extreme environments.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
