Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing, and more specifically, it relates to a battery loading device. This utility model also relates to a battery module installation device. Background Technology

[0002] A battery box is a group of batteries consisting of several individual batteries, a box body, a battery management system, and related installation structural components (equipment). It has a standard battery box structure, battery box monitoring equipment, battery box connectors, and battery box environmental control equipment.

[0003] Functionally, the main purpose of a battery pack is to help ventilate and dissipate heat from the batteries; to insulate and waterproof them; and to protect them from impacts. Battery boxes are mainly distinguished by the size and quantity of batteries and their placement method. They are generally divided into three main categories: vertical, horizontal, and manually operated, and the number of batteries they can store also varies.

[0004] 1. Vertical type: The batteries in the battery box are placed vertically. The batteries can be arranged in parallel or in series. The characteristic of vertical battery boxes is that they occupy less area on the bottom plate of the product and are suitable for products with a small bottom area.

[0005] 2. Horizontal type: The batteries in the battery box are placed horizontally. The batteries can be placed side by side or in series. The characteristic of the horizontal battery box is that it occupies a larger area of ​​the bottom plate, but the center of gravity is lower, making it suitable for larger products.

[0006] 3. Hand-operated type: The battery compartment and the toy itself are separate parts. Power is supplied via a long cord connecting the battery compartment and the product. This type is mostly used in toys. The switch is located on the battery compartment and usually controls the conductivity and polarity of the power supply, allowing children to hold the battery compartment and control the product to stop, start, move forward, or move backward at any time.

[0007] During the process of introducing battery modules into the battery box, it is necessary to ensure precise alignment between the battery and the electrical connection points inside the battery box. Currently, batteries with larger volume and weight are generally assembled into the battery box by hoisting, or the lighter battery box is installed on the battery after the battery is fixed. However, the inventors found that the positioning accuracy of the existing assembly method cannot meet the requirements during the battery box installation process, and misalignment is prone to occur during the introduction of battery modules. The guide structure set in the battery box increases the overall weight of the battery box and cannot play the expected positioning and guiding role for the precise positioning of the battery. Improvement is urgently needed. Utility Model Content

[0008] The purpose of this utility model is to provide a battery loading device to solve the technical problem that the positioning accuracy cannot meet the usage requirements during the process of loading battery modules into the battery box.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a battery insertion device, comprising:

[0010] A guiding assembly includes a guide cylinder and a guide rod. The guide cylinder is disposed on the outer periphery of the battery. The axes of the guide rod and the guide cylinder are coaxial and both extend in the vertical direction. The guide cylinder is sleeved on the outer periphery of the guide rod and is adapted to guide the battery with the guide cylinder into the battery housing.

[0011] A telescopic assembly includes a first telescopic rod, and at least two guide rods. The first telescopic rod includes a first sleeve rod, a first inner rod, and a positioning pin. One end of the first sleeve rod is connected to one of the guide rods, and the other end is telescopically sleeved on the outer periphery of the first inner rod along its own axis. One end of the first inner rod is inserted into the first sleeve rod, and the other end is connected to the other guide rod. The axes of the first sleeve rod and the first inner rod both extend along a first horizontal direction. A plurality of first positioning holes are uniformly formed on the outer periphery of the first sleeve rod along its own axis, and a plurality of second positioning holes are formed on the outer periphery of the first inner rod along its own axis. The positioning pin is used to form a pin connection and fixation between any of the first positioning holes and any of the second positioning holes.

[0012] In one feasible implementation, the guide assembly further includes a positioning screw, and the side wall of the guide cylinder has a threaded through hole. The axis of the threaded through hole extends along the radial line of the guide cylinder. The positioning screw is threadedly adapted to the threaded through hole, and one end of the positioning screw located inside the guide cylinder abuts against the outer wall of the guide rod.

[0013] In one feasible implementation, both ends of the first telescopic rod are provided with mounting rods, the mounting rods extend along a second horizontal direction, the second horizontal direction is perpendicular to the first horizontal direction, and the mounting rods are provided with mounting holes for mounting the guide rods.

[0014] In one feasible implementation, the positioning screw is connected to a rubber pressing block on one side inside the guide cylinder. The rubber pressing block is located inside the guide cylinder and abuts against the guide rod.

[0015] In one feasible implementation, both the first sleeve rod and the first inner rod have square cross-sectional shapes.

[0016] In one feasible implementation, the inner surface of the guide cylinder is provided with a protruding trapezoidal internal thread, the trapezoidal internal thread is coaxial with the guide cylinder, the outer periphery of the guide rod is provided with a trapezoidal external thread, the trapezoidal internal thread is thread-fitted with the trapezoidal external thread, and the outer periphery of the trapezoidal external thread is slidably fitted with the inner wall of the guide cylinder.

[0017] In one feasible implementation, the guide rod is rotatably connected to the mounting hole, and the top end of the guide rod is provided with a spline.

[0018] Compared with the prior art, the advantages of the battery loading device provided by this utility model are as follows:

[0019] Firstly, this invention utilizes the coaxial sleeve connection between the guide cylinder and the guide rod. During the battery module's entry into the housing, the guide cylinder moves axially along the guide rod, enabling precise insertion of the battery into the housing along the axial direction. This solves the jamming problem caused by alignment deviations during traditional battery installation. Secondly, the multi-hole pin connection structure of the first telescopic rod allows for adjustment of the distance between the two guide rods, enabling the guide assembly to adapt to battery modules of different diameters, achieving a "one machine, multiple uses" technical effect and significantly improving the equipment's versatility. The square rod design of the telescopic assembly further enhances the structure's torsional resistance, ensuring stability during the guiding process.

[0020] Secondly, this utility model can achieve quick locking and positioning of the guide cylinder and guide rod by radially abutting the threaded through hole, so that the telescopic component can be firmly connected to the battery module in the lifting state. When adjusted to the appropriate position, the battery module can be lowered along the guide rod by loosening the screw. The screw can also prevent uncontrollable axial displacement and radial deviation of the component between the guide rod and the guide cylinder.

[0021] Furthermore, this invention allows the guide assembly to form a two-dimensional adjustable structure in the horizontal plane through the mounting holes in the second horizontal direction. Combined with the axial adjustment function of the first telescopic rod, it achieves bidirectional dimensional adaptability of the guide system in both the horizontal and vertical directions, precisely matching the length and width differences of rectangular battery boxes, significantly improving the equipment's compatibility with non-standard battery boxes. Moreover, the flexible contact surface made of a buffer material can evenly distribute compressive stress during locking, avoiding scratches on the guide rod surface caused by direct contact with traditional screws, and enhancing the anti-slip effect by increasing the coefficient of friction, thus solving the problem of precision guide assembly accuracy degradation during repeated disassembly and assembly.

[0022] Furthermore, in the above implementation scheme, the geometric constraints of the cross-sectional shape completely eliminate the circumferential rotation phenomenon that may occur when adjusting the length of the telescopic rod, ensuring that the axis of the multi-guide rod system is always in the same vertical plane. This feature, together with the positioning pin mechanism, forms a double error-proof guarantee, ensuring the straightness requirements of the path during the installation of large-size battery modules. In addition, the rectangular cross-section ensures that the telescopic rod has sufficient structural strength, preventing problems such as twisting and deformation of the telescopic rod during the lifting of battery modules.

[0023] Furthermore, this invention combines the axial locking function of the threaded pair with the sliding guiding function by setting a trapezoidal thread fit structure. During adjustment, the trapezoidal thread provides a precise axial feed amount, and after locking, the threaded pair forms a self-locking angle to achieve reliable fixation. This solves the structural redundancy problem of separate sliding fit and fixing device in traditional guiding mechanisms, enabling the system to have both fine-tuning accuracy and load-bearing stability.

[0024] In addition to the benefits mentioned above, the standardized interface design enables quick adjustment of the guide rod height. Operators can use a universal spline wrench for precise rotational fine-tuning.

[0025] Another objective of this invention is to provide a battery module installation device, including the battery insertion device mentioned above.

[0026] Compared with the prior art, the battery module installation equipment of this utility model has all the advantages of the battery box inlet device mentioned above. At the same time, by integrating the above-mentioned innovative guiding system, this utility model improves the installation efficiency of the battery module and is suitable for the large-scale industrial production of new energy vehicle battery packs.

[0036] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0037] Please refer to the following: Figures 1 to 2The present invention provides a battery box insertion device. The battery box insertion device of this application includes a guide assembly 1 and a telescopic assembly 2. The guide assembly 1 includes a guide cylinder 11 and a guide rod 12. The guide cylinder 11 is disposed on the outer periphery of the battery. The axes of the guide rod 12 and the guide cylinder 11 are coaxial and both extend in the vertical direction. The guide cylinder 11 is sleeved on the outer periphery of the guide rod 12 and is adapted to guide the battery with the guide cylinder 11 into the battery box. The telescopic assembly 2 includes a first telescopic rod 21, and there are at least two guide rods 12. The first telescopic rod 21 includes a first sleeve rod 211, a first inner rod 212, and a positioning pin 213. A set of rods 211 has one end connected to one of the guide rods 12, and the other end is telescopically sleeved on the outer periphery of the first inner rod 212 along its own axis. One end of the first inner rod 212 is inserted into the first set of rods 211, and the other end is connected to another guide rod 12. The axes of the first set of rods 211 and the first inner rod 212 both extend along the first horizontal direction. The outer periphery of the first set of rods 211 is evenly provided with a plurality of first positioning holes along its own axis. The outer periphery of the first inner rod 212 is provided with a plurality of second positioning holes along its own axis. The positioning pin 213 is used to form a pin connection between any first positioning hole and any second positioning hole.

[0038] In this embodiment, the guide cylinder 11 and guide rod 12 are coaxially fitted together. The guide cylinder 11 moves axially along the guide rod 12 as the battery module enters the housing, thus achieving precise insertion of the battery into the battery housing along the axial direction. This solves the jamming problem caused by alignment deviations during traditional battery installation. Simultaneously, the multi-hole pin connection structure of the first telescopic rod 21 allows for adjustment of the distance between the two guide rods 12, enabling the guide assembly 1 to adapt to battery modules of different diameters, achieving a "one machine, multiple uses" technical effect and significantly improving the equipment's versatility. The square rod design of the telescopic assembly 2 further enhances the structure's torsional resistance, ensuring stability during the guiding process.

[0039] To facilitate the lifting of the battery module via the telescopic rod, in one specific embodiment, the guide assembly 1 further includes a positioning screw. A threaded through hole is provided on the side wall of the guide cylinder 11, with the axis of the threaded through hole extending radially along the guide cylinder 11. The positioning screw is threadedly fitted into the threaded through hole, and one end of the positioning screw located inside the guide cylinder 11 abuts against the outer wall of the guide rod 12. Preferably, the end of the positioning pin 213 in this embodiment may also be provided with a lifting ring or other structure to facilitate lifting. Compared to the prior art, this invention, through the radial abutment cooperation between the threaded through hole and the guide rod 12, enables rapid locking and positioning of the guide cylinder 11 and the guide rod 12, allowing the telescopic assembly 2 to be firmly connected to the battery module in the lifting state. When adjusted to a suitable position, the battery module can be lowered along the guide rod 12 by loosening the screw. Furthermore, the screw also prevents uncontrollable axial displacement and radial deviation between the guide rod 12 and the guide cylinder 11.

[0040] In one specific embodiment, both ends of the first telescopic rod 21 are provided with mounting rods 214, which extend along a second horizontal direction perpendicular to the first horizontal direction. The mounting rods 214 have mounting holes for mounting guide rods 12, thus forming a two-dimensional adjustable structure of the guide assembly 1 in the horizontal plane. Combined with the axial adjustment function of the first telescopic rod 21, the guide system achieves bidirectional dimensional adaptability in both the horizontal and vertical directions, accurately matching the length and width differences of rectangular battery boxes, significantly improving the equipment's compatibility with non-standard battery boxes.

[0041] In one specific embodiment, a rubber pressing block is connected to one side of the positioning screw inside the guide cylinder 11. The rubber pressing block is located inside the guide cylinder 11 and abuts against the guide rod 12. The rubber pressing block can be made of rubber so that the compressive stress is evenly distributed during the locking process by pressing the guide rod 12 with the rubber pressing block. This avoids scratches on the surface of the guide rod 12 caused by direct contact with traditional screws, and enhances the anti-slip effect by increasing the friction coefficient. This solves the problem of accuracy decay of the precision guide assembly 1 during repeated disassembly and assembly. In addition, the screw setting can also prevent uncontrollable axial displacement and radial deviation of the assembly between the guide rod 12 and the guide cylinder 11.

[0042] In one specific embodiment, both the first rod 211 and the first inner rod 212 have square cross-sectional shapes. This geometric constraint of the cross-sectional shape eliminates potential circumferential rotation of the telescopic rod during length adjustment, ensuring that the axes of the multi-guide rod 12 system remain in the same vertical plane. This feature, together with the positioning pin 213 mechanism, provides dual error prevention, ensuring the straightness of the path during the installation of large-size battery modules. Furthermore, the rectangular cross-section ensures sufficient structural strength for the telescopic rod, preventing twisting or deformation during the lifting of the battery module.

[0043] In one specific embodiment, the inner surface of the guide cylinder 11 is provided with a protruding trapezoidal internal thread, which is coaxial with the guide cylinder 11. The outer periphery of the guide rod 12 is provided with a trapezoidal external thread 121, which is thread-fitted with the trapezoidal internal thread and the trapezoidal external thread 121. The outer periphery of the trapezoidal external thread 121 is also slidably fitted with the inner wall of the guide cylinder 11. In this way, this embodiment can combine the axial locking function and the sliding guiding function of the threaded pair by setting a trapezoidal thread fit structure. During adjustment, the inner and outer trapezoidal threads provide a precise axial feed amount. After locking, the threaded pair forms a self-locking angle to achieve reliable fixation. This solves the structural redundancy problem of the separate sliding fit and fixing device in traditional guide mechanisms, enabling the system to have both fine-tuning accuracy and load-bearing stability.

[0044] In one specific embodiment, the guide rod 12 is rotatably connected to the mounting hole, and the top of the guide rod 12 is provided with a spline. This allows for quick height adjustment of the guide rod 12 through a standardized interface design, and operators can use a universal spline wrench for precise rotational fine-tuning.

[0045] In summary, compared with existing technologies, the battery loading device provided by this utility model achieves precise loading of the battery module into the battery box along the axis through the coaxial sleeve of the guide cylinder 11 and the guide rod 12, solving the jamming problem caused by traditional alignment deviations. Combined with the multi-hole pin connection structure of the first telescopic rod 21, the spacing of the guide rod 12 can be infinitely adjusted to accommodate battery modules of different diameters, improving the equipment's versatility. The added threaded through hole and radial abutment positioning screw can quickly lock the guide cylinder 11 and guide rod 12 during lifting, preventing axial displacement and radial deviation. Simultaneously, the flexible contact surface of the buffer material evenly distributes compressive stress, preventing surface damage to the guide rod 12 and enhancing the anti-slip effect. The second horizontal mounting hole and the axial adjustment of the telescopic rod form a two-dimensional adjustable structure, precisely matching the length and width differences of the rectangular battery box, and is compatible with non-standard boxes. Square cross-section rods are used to eliminate circumferential rotation during telescopic adjustment. The coplanar straightness of the multi-guide rod 12 system is doubled by the positioning pin 213. The axial locking and sliding guiding functions are integrated through the trapezoidal thread pair to achieve a balance between fine adjustment accuracy and load-bearing stability. Finally, an integrated battery box guide system is formed that combines efficient positioning, multi-dimensional adaptation, anti-torsion and anti-deviation, and durability for repeated disassembly and assembly.

[0046] Based on the same inventive purpose, another objective of this utility model is to provide a battery module installation device, including the battery insertion device mentioned above.

[0047] In practical implementation, the battery module installation equipment of this utility model has all the advantages of the battery box inlet device mentioned above. At the same time, by integrating the above-mentioned innovative guidance system, this utility model improves the installation efficiency of the battery module and is suitable for large-scale industrial production of new energy vehicle battery packs.

[0048] 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.
