Description

Technical Field

[0001] This utility model is an electric hoisting clamp for battery modules. Background Technology

[0002] In the current battery module production and assembly process, module hoisting operations are generally carried out manually. Traditional manual hoisting methods have many drawbacks, including low efficiency and significant safety hazards. Previously, a single battery module hoisting operation typically required at least three workers working together: one to align the tooling, and two to control the hoisting operation. This method heavily relies on manual coordination, resulting in a significant waste of human resources.

[0003] Meanwhile, the use of traditional hoisting fixtures also has significant shortcomings. In actual operation, multiple alignment adjustments are required between the fixture and the module to achieve accurate installation, increasing operation time, reducing production cycle time, and seriously affecting assembly efficiency. More seriously, manual installation of fixtures is unpredictable. If the fixture is not installed properly, or if components are aged or worn due to long-term use, the module is very likely to fall off during hoisting, which may lead to equipment damage or even personal injury, posing an extremely high safety risk.

[0004] In view of the above problems, there is an urgent need for an electric hoisting device with a reasonable structure, simple operation, and high safety and automation level to solve the problems of high manpower consumption, low operating efficiency, and insufficient safety guarantee in the existing technology. Therefore, the present invention provides an electric hoisting clamp for battery modules, which aims to improve the automation and safety performance of hoisting operations, reduce manpower input, and improve overall operation efficiency and reliability. Utility Model Content:

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an electric hoisting clamp for battery modules.

[0006] An electric lifting fixture for battery modules includes a left fixture, a right fixture, a linear guide rail, a slider, a drive mechanism, and a linkage mechanism. The left and right fixtures are fixedly connected to the slider, and the slider slides in cooperation with the linear guide rail. The linkage mechanism includes a support, a first connecting rod, a second connecting rod, and a rotating connecting rod. The support is located between the left and right fixtures. One end of the first and second connecting rods is hinged to one end of the rotating connecting rod, and the other end is hinged to the left or right fixture, respectively. The center of the rotating connecting rod is rotatably connected to the support.

[0007] Furthermore, the drive mechanism includes an electric telescopic rod, which is fixed to the left or right clamp, and its telescopic end is connected to the support.

[0008] Furthermore, the guide rail includes two parallel guide rods, with both ends of the guide rods fixed to the mounting plate. The slider is slidably sleeved on the guide rods, and the left or right clamp is equipped with at least two sliders located on different guide rods.

[0009] Furthermore, the support is provided with several mounting seats, which are sleeved on the guide rod.

[0010] Furthermore, the left or right clamp includes a fixed base and a clamp plate. The clamp plate is fixed to the side of the fixed base, and the slider is disposed on the top of the fixed base. At least two positioning posts are provided on the opposite surfaces of the clamp plates of the left and right clamps. The positioning posts are used to cooperate with the positioning holes on the module.

[0011] Furthermore, the fixed base includes at least two parallel right-angled triangular brackets, with fixed plates fixed to the two right-angled sides of the brackets. The fixed plates are used to install sliders or clamping plates.

[0012] Furthermore, the base of the electric telescopic pole is installed on the center line of the fixed base.

[0013] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0014] Firstly, the electric telescopic boom enables precise control of the clamping action, significantly improving automation and operational efficiency compared to traditional manual operation. The electric control system offers rapid response and facilitates integration into automated production lines, enabling intelligent hoisting operations.

[0015] Secondly, a linkage mechanism is used to achieve synchronous mirror motion of the left and right clamps. This compact structure and stable transmission effectively avoid problems such as uneven load or clamp asynchrony during clamping, thus improving the safety and reliability of lifting operations. The coordinated operation between the rotating linkage and the double-sided linkages ensures the consistency and coordination of the clamp movements.

[0016] Furthermore, the guide rail and slider form a stable linear motion guiding system. Combined with a multi-point support structure, such as a double guide rod design and multiple slider configuration, it significantly enhances the positioning accuracy and resistance to lateral forces during fixture operation, ensuring smooth and jam-free fixture movement.

[0017] In addition, the positioning pin structure on the clamp plate can be used in conjunction with the positioning holes on the battery module, which improves the accuracy of clamping and positioning, prevents the module from slipping or shifting during transportation, and ensures the quality of operation.

Detailed Implementation

[0021] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. 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.

[0022] An electric hoisting fixture for battery modules includes a left fixture, a right fixture, a linear guide rail 1, a slider 3, a drive mechanism, and a linkage mechanism. The left fixture and the right fixture are fixedly connected to the slider 3, and the slider 3 is slidably engaged with the linear guide rail 1. The linkage mechanism includes a support 5, a first connecting rod 11, a second connecting rod 13, and a rotating connecting rod 12. The support 5 is located between the left fixture and the right fixture. One end of the first connecting rod 11 and the second connecting rod 13 are respectively hinged to one end of the rotating connecting rod 12, and the other end is respectively hinged to the left fixture or the right fixture. The center of the rotating connecting rod 12 is rotatably connected to the support 5.

[0023] This electric lifting clamp is mainly used for clamping and lifting battery modules. The left and right clamps are mounted on linear guide rails 1 via sliders 3, allowing for sliding adjustment along the guide rails 1. The rotating link 12 in the linkage mechanism is mounted on the central support 5 and can rotate around its center. The first link 11 and the second link 13 are connected to the two ends of the rotating link 12 and are hinged to the left and right clamps respectively. When the drive mechanism drives the rotating link 12 to rotate, the geometry of the linkage mechanism causes the left and right clamps to move closer to or further away from the center, thereby clamping or releasing the battery module. This mechanism achieves bidirectional synchronous clamping through a single-point drive, featuring a compact structure and simple operation.

[0024] This lifting fixture features a compact structure and easy installation, enabling automatic clamping of battery modules during lifting, thus improving lifting efficiency and safety. The linkage mechanism ensures synchronized movement of the fixture, effectively preventing issues such as uneven loading or clamping. The fixture's design guarantees the stability of the modules during handling, avoiding errors caused by manual operation and enhancing the overall level of automation.

[0025] In one possible implementation, the drive mechanism includes an electric telescopic rod 4, which is fixed to the left or right clamp, and its telescopic end is connected to the support 5.

[0026] The electric telescopic rod 4 serves as the drive source and is fixedly installed on the left or right clamp, with its telescopic end connected to the support 5 in the middle. When the electric telescopic rod 4 is working, its telescopic movement pushes or pulls the support 5, thereby causing the clamp mounted on the slider 3 to slide along the linear guide rail 1. Through the coordination of the linkage mechanism, the left and right clamps can synchronously clamp or release the battery module, completing the automated clamping.

[0027] This structure is powered by an electric telescopic boom 4, enabling precisely controlled clamping actions and a high degree of automation. Electric drive eliminates manual intervention, improving lifting safety and consistency. The equipment has a fast response time and is suitable for industrial automated production lines.

[0028] In one possible implementation, the guide rail 1 includes two parallel guide rods, with both ends of the guide rods fixed to the mounting plate 2. The slider 3 is slidably sleeved on the guide rods, and the left or right clamp is equipped with at least two sliders 3 located on different guide rods.

[0029] The structure employs two parallel guide rods as the guide rail system 1, with both ends fixed by fixing plates 8, providing excellent support and alignment capabilities. Slider 3 is fitted onto the outer surface of the guide rods through an internal hole structure, achieving a low-friction sliding fit. Each clamp is distributed on the two guide rods via two sliders 3, forming a stable guiding mechanism that effectively prevents the clamps from tilting or rotating, ensuring symmetry and stability during clamping.

[0030] By incorporating a dual-guide rod and multi-slider structure, the positioning stability and operational smoothness of the fixture are improved. This structure enhances the overall rigidity and resistance to off-center loads of the fixture, contributing to high-precision and high-reliability clamping operations.

[0031] In one possible implementation, the support 5 is provided with a plurality of mounting seats 6, which are sleeved on the guide rod.

[0032] Supports 5 are positioned between guide rods, and several mounting seats 6 are installed thereon. These seats are fitted onto the outside of the guide rods through inner holes, providing guidance and support for the guide rods. These mounting seats 6 not only provide stable support for supports 5, but also allow for fine-tuning of the overall position by adjusting their positions on the guide rods, thereby optimizing the clamping center of the fixture and the lifting balance point.

[0033] The structure of mounting base 6 improves the installation stability and smooth sliding of support 5 on guide rod, while facilitating maintenance and disassembly, enhancing the modularity of the whole machine, and adapting to the changing requirements of different module sizes.

[0034] In one possible implementation, the left or right clamp includes a fixed base and a clamp plate 9. The clamp plate 9 is fixed to the side of the fixed base, and the slider 3 is disposed on the top of the fixed base. At least two positioning posts 10 are provided on the opposite surfaces of the clamp plates 9 of the left and right clamps. The positioning posts 10 are used to cooperate with the positioning holes on the module.

[0035] The clamping structure is supported by a fixed base, and a clamping plate 9 is fixedly installed on one side of the base to realize the module contact and clamping functions. The slider 3 is set on the top of the fixed base and cooperates with the guide rod to form a sliding support. The clamping plate 9 has multiple positioning posts 10 on the side facing the battery module. These positioning posts 10 are inserted into the preset positioning holes of the module during clamping to ensure that the module is accurately and reliably positioned during clamping.

[0036] The positioning column 10 structure effectively improves the accuracy and consistency of module clamping, prevents the module from shifting or rotating during handling, and ensures that the fixture operates efficiently and stably in the automated production line.

[0037] In one possible implementation, the fixing base includes at least two parallel right-angled triangular brackets 7, with fixing plates 8 fixedly mounted on the two right-angled sides of the brackets 7. The fixing plates 8 are used to mount sliders 3 or clamping plates 9.

[0038] The mounting base employs multiple right-angled triangular support brackets 7, which are arranged parallel to each other at intervals. Several fixing plates 8 are fixed to each bracket via their two right-angled sides. Slider blocks 3 and clamping plates 9 are mounted on the fixing plates 8, forming a robust connection structure. This structure makes reasonable use of the geometric properties of triangles to enhance the stability and load-bearing capacity of the frame.

[0039] The bracket 7 structure enhances the overall strength and durability of the fixed base, effectively resisting lateral and vertical loads, allowing the lifting clamp to maintain good structural stability during long-term operation and reducing the risk of deformation or loosening.

[0040] In one possible implementation, the base of the electric telescopic rod 4 is mounted on the center line of the fixed base.

[0041] The base of the electric telescopic rod 4 is designed to be installed at the center line of the fixed base, ensuring that its force application point is on the axis of symmetry of the clamping structure. In this way, during electric telescopic movement, the pushing or pulling force can be symmetrically transmitted through the clamp, ensuring the stability and synchronicity of the clamping action and avoiding off-center loading.

[0042] By installing the electric telescopic rod 4 in the center, the driving stability and force balance are effectively improved, the risk of clamp deformation caused by force deviation of the mechanism is reduced, and the overall hoisting efficiency and equipment reliability are improved.

[0043] Working principle: The telescopic movement of the electric telescopic rod 4 drives one side of the clamp to move along the guide rail 1, which in turn causes the connecting rod connected to that side to shift. The movement of the connecting rod causes the central rotating connecting rod 12 to rotate around the support 5, while simultaneously driving the connecting rod on the other side to move synchronously, thereby causing the clamp on the other side to move relative to the guide rail 1. Throughout the process, the left and right clamps move synchronously in a symmetrical mirror manner, achieving precise control of the clamp spacing.

[0044] 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.
