Description

Technical Field

[0001] This utility model relates to the field of fuel cell technology, and in particular to a modular assembly vehicle for fuel cell assembly. Background Technology

[0002] A fuel cell is a device that directly converts the chemical energy of fuel and oxidant into electrical energy through an electrochemical reaction. It is characterized by high efficiency, cleanliness, and quiet operation. Its core working principle is based on the reverse process of water electrolysis. Through the action of electrodes and electrolytes, the fuel undergoes an oxidation reaction at the anode, releasing electrons. These electrons form an electric current through an external circuit. At the same time, the oxidant combines with electrons and hydrogen ions at the cathode to generate water. The entire process involves no combustion, and the main emission is water (if hydrogen is used as fuel). It is widely used in automobiles, distributed power generation, and portable power sources, and is considered one of the important technologies for achieving zero emissions in the future energy system, playing a key role in energy transition and sustainable development.

[0003] Modular assembly vehicles for fuel cell assembly are specialized equipment integrating automated control, precision mechanical positioning, and fuel cell component adaptation design. Through modular structures, they achieve efficient and precise assembly of the fuel cell stack and auxiliary systems, facilitating large-scale fuel cell production. Existing modular assembly vehicles use bolts to fix different modules by reserving bolt interfaces at module connections. However, after repeated disassembly and assembly, the threads of the bolts and bolt holes may strip or deform (especially in aluminum alloy modules), leading to decreased connection strength and subsequent module loosening. Current technology involves welding sliders to the bottom of the modules, inserting them into the guide groove of a magnetic guide rail, and manually or via a robotic arm pushing the modules along the guide rail. The guide rail guide groove can forcibly constrain the lateral displacement of the modules. Initial module positioning is achieved using positioning scales or photoelectric sensors on the side of the guide rail. However, in the fuel cell assembly environment, ferromagnetic impurities (such as metal debris and screws) can mix into the magnetic guide rail's adsorption surface, creating a "magnetic short circuit," causing a sharp drop in local adsorption force and reducing the stability of the modular fixation. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a modular assembly vehicle for fuel cell assembly, aiming to improve the problem in the prior art where ferromagnetic impurities (such as metal debris and screws) are mixed into the magnetic guide rail adsorption surface in the fuel cell assembly environment, forming a "magnetic short circuit" that causes a sharp drop in local adsorption force and reduces the stability of modular fixation.

The outer wall of the sliding plate is fixedly connected to the inner wall of the protective frame, and the interior of the sliding plate is slidably connected to the outer wall of the long rod. Multiple slots are formed at the top of the long rod, all of which are formed on the front side of the fixing plate. A support rod is slidably connected to the interior of the long rod, and the front end of the outer wall of the support rod is fixedly connected to the front side of the inner wall of the protective frame.

[0008] As a further description of the above technical solution:

[0009] The lifting mechanism includes a top plate, which is installed on the top of the outer wall of the support plate. A slide is fixedly connected to the bottom of the outer wall of the top plate. A lifting frame is fixedly connected to the bottom of the outer side of the top plate. The top of the front end of the lifting frame is slidably connected to the inside of the slide. A power assembly is installed at the bottom of the top plate.

[0010] As a further description of the above technical solution:

[0011] The power assembly includes a turntable mounted on the bottom of a top plate. A threaded rod is fixedly connected to the rear side of the outer wall of the turntable.

A slider is threadedly connected to the outer wall of the threaded rod. A base plate is fixedly connected to the outer wall of the limit frame. The top rear end of the outer wall of the base plate is fixedly connected to the bottom rear end of the outer wall of the lifting frame. The bottom front end of the outer wall of the lifting frame is fixedly connected to the outer wall of the slider.

[0012] As a further description of the above technical solution:

[0013] The support plate has protective frames installed on the top left and right ends of its outer wall. The bottom ends of the multiple protective frames are slidably connected to the inside of the limiting groove. The top of the protective frame is equipped with a clamping rotator.

Detailed Implementation

[0031] 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.

[0032] Reference Figure 3 , Figure 4 and Figure 5This utility model provides an embodiment of a modular assembly vehicle for fuel cell assembly, comprising a support plate 1, a fixing mechanism 2 installed on the outer side of the support plate 1 for quick disassembly, and a lifting mechanism 3 installed at the top of the outer wall of the support plate 1 for lifting; the fixing mechanism 2 includes a push plate 201 installed on the outer side of the support plate 1, with long rods 202 fixedly connected to the left and right ends of the front side of the outer wall of the push plate 201, protective frames 203 installed on the outer sides of the multiple long rods 202, the bottom of the outer walls of the multiple protective frames 203 fixedly connected to the top of the outer wall of the support plate 1, multiple limiting grooves 204 opened at the top of the protective frames 203, and multiple screws 205 threadedly connected to the outer walls of the multiple protective frames 203 on opposite sides. Multiple locking components 206 are fixedly connected to the outer wall of the long rod 202. Each locking component 206 includes a fixing plate 2061. The fixing plates 2061 are installed on the outer wall of the long rod 202. A spring 2062 is fixedly connected to the front side of the outer wall of the fixing plate 2061. A sliding plate 2063 is fixedly connected to the front end of the outer wall of the spring 2062. The outer wall of the sliding plate 2063 is fixedly connected to the inner wall of the protective frame 203. The interior of the sliding plate 2063 is slidably connected to the outer wall of the long rod 202. Multiple slots 2065 are opened at the top of the long rod 202. The slots 2065 are all opened on the front side of the fixing plate 2061. A support rod 2064 is slidably connected to the interior of the long rod 202. The front end of the outer wall of the support rod 2064 is fixedly connected to the front side of the inner wall of the protective frame 203.

[0033] Specifically, pushing the push plate 201 can cause the long rod 202 to slide inside the protective frame 203. Multiple fixing plates 2061 welded on the long rod 202 have springs 2062 fixed at their front ends that can slide on the outside of the long rod 202. The sliding plate 2063 is welded to the protective frame 203 and its middle part allows the long rod 202 to slide. When modular disassembly of the assembly vehicle is required, pushing the push plate 201, through the fixing restriction of the sliding plate 2063, allows the fixing plate 2061 to squeeze the spring 2062 and expose the slot 2065 at the bottom of the limiting groove 204. After the protective frame 12 is inserted into the slot 2065 through the limiting groove 204, releasing the push plate 201, the elastic compression of the spring 2062 can achieve quick fixing and disassembly of the protective frame 12. The screws 205 on the outside of the protective frame 203 can further fix the protective frame 12 to ensure its stability during operation, ultimately realizing the modularization of the fuel cell assembly vehicle.

[0034] Reference Figure 1 , Figure 2 and Figure 6The lifting mechanism 3 includes a top plate 301, which is installed on the top of the outer wall of the support plate 1. A slide 302 is fixedly connected to the bottom of the outer wall of the top plate 301. A lifting frame 303 is fixedly connected to the bottom outer side of the top plate 301. The top front end of the lifting frame 303 is slidably connected to the inside of the slide 302. A power assembly 304 is installed at the bottom of the top plate 301. The power assembly 304 includes a turntable 3041, which is installed at the bottom of the top plate 301. The rear side of the outer wall of the turntable 3041 A threaded rod 3042 is fixedly connected. A limit frame 3044 is installed on the outside of the threaded rod 3042. The outer wall of the threaded rod 3042 is rotatably connected to the middle of the limit frame 3044. A slider 3043 is threadedly connected to the outer wall of the threaded rod 3042. A base plate 3045 is fixedly connected to the outer wall of the limit frame 3044. The top and rear end of the outer wall of the base plate 3045 are fixedly connected to the bottom of the rear end of the outer wall of the lifting frame 303. The bottom of the front end of the outer wall of the lifting frame 303 is fixedly connected to the outer wall of the slider 3043.

[0035] Specifically, rotating the turntable 3041 causes the threaded rod 3042 on its rear side to rotate in the middle of the limiting frame 3044. The rotation of the limiting frame 3044 restricts the movement of the slider 3043, which is connected to the outside of the threaded rod 3042 by threads. This causes the slider 3043 to move the front end of the lifting frame 303. Since the top of the front end of the lifting frame 303 can slide inside the slide 302 and the bottom of the rear end of the lifting frame 303 is welded to the top rear end of the base plate 3045, the lifting frame 303 can be raised and lowered when the slider 3043 moves. This causes the top plate 301 to move vertically with the raising and lowering of the lifting frame 303, thus enabling fuel cells of different sizes and specifications to be raised and lowered to a suitable position for clamping and rotating by the clamping rotator 11.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The top left and right ends of the outer wall of the support plate 1 are equipped with protective frames 12. The bottom ends of the multiple protective frames 12 are slidably connected to the inside of the limiting groove 204. The top of the protective frame 12 is equipped with a clamping rotator 11. The middle of the multiple clamping rotators 11 is equipped with a battery body 10. The battery body 10 is installed on the top of the outer side of the support plate 1. The front side of the outer wall of the protective frame 12 is fixedly connected with a fixing frame 6. The outer walls of the multiple fixing frames 6 are threaded with bolts 7 at the ends away from each other. The middle of the fixing frame 6 is equipped with a push rod 4. The bottom end of the push rod 4 is fixedly connected with a crossbar 5. The left and right sides of the bottom rear end of the outer wall of the support plate 1 are fixedly connected with directional wheels 9. The left and right sides of the bottom front end of the outer wall of the support plate 1 are fixedly connected with universal wheels 8.

[0037] Specifically, a protective frame 12 is welded to the outer wall of the support plate 1. A clamping rotator 11 is installed at the top of the protective frame 12, which can clamp the battery body 10 and drive it to rotate. The battery body 10 is located on the top of the outer side of the support plate 1. There is a fixing frame 6 on the front side of the outer wall of the protective frame 12. There are bolts 7 at the ends of the outer walls of multiple fixing frames 6. There is a push rod 4 in the middle of the fixing frame 6. There is a crossbar 5 at the bottom end of the push rod 4. Pushing the push rod 4 can drive the support plate 1 to move. There are directional wheels 9 on the left and right sides of the bottom rear end of the outer wall of the support plate 1. There are universal wheels 8 on the left and right sides of the bottom front end of the outer wall of the support plate 1. The directional wheels 9 and universal wheels 8 work together to enable the support plate 1 to move and turn flexibly. All components work together to ensure the normal operation and movement of the equipment.

[0038] Working principle: Pushing the push plate 201 can drive the long rod 202 to slide inside the protective frame 203. Multiple fixing plates 2061 welded on the long rod 202 have springs 2062 fixed at their front ends that can slide on the outside of the long rod 202. The sliding plate 2063 is welded to the protective frame 203 and its middle part allows the long rod 202 to slide. When modular disassembly of the assembly vehicle is required, pushing the push plate 201, through the fixing restriction of the sliding plate 2063, allows the fixing plate 2061 to squeeze the spring 2062 and expose the slot 2065 at the bottom of the limiting groove 204. After the protective frame 12 is inserted into the slot 2065 through the limiting groove 204, the push plate 201 is released and the elastic compression of the spring 2062 can realize the quick fixing and disassembly of the protective frame 12. The screws 205 on the outside of the protective frame 203 can further fix the protective frame 12 to ensure its stability during operation, and finally realize the modularization of the fuel cell assembly vehicle.

[0039] Rotating the turntable 3041 causes the threaded rod 3042 on its rear side to rotate in the middle of the limiting frame 3044. The rotation of the limiting frame 3044 restricts the movement of the slider 3043, which is connected to the outside of the threaded rod 3042 by threads. This causes the slider 3043 to move the front end of the lifting frame 303. Since the top of the front end of the lifting frame 303 can slide inside the slide 302 and the bottom of the rear end of the lifting frame 303 is welded to the top rear end of the base plate 3045, the lifting frame 303 can be raised and lowered when the slider 3043 moves. This causes the top plate 301 to move vertically with the raising and lowering of the lifting frame 303, thus enabling fuel cells of different sizes and specifications to be raised and lowered to a suitable position for clamping and rotating by the clamping rotator 11.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
