Description

Technical Field

[0001] This utility model relates to the field of coolant production, and specifically discloses a filling and conveying structure for thermal management fluid in new energy vehicles. Background Technology

[0002] Thermal management fluids (including coolant and antifreeze) for new energy vehicles are important media to ensure the normal operation of electric vehicle power batteries, motors, and electronic control systems. As a key link in the production line, the filling and conveying structure directly affects production efficiency and product quality. With the rapid development of the new energy vehicle industry, higher requirements have been placed on the filling accuracy, production efficiency, and automation level of thermal management fluids. Traditional filling and conveying structures mainly use crawler or chain conveyor belts, where empty cans are placed on the conveyor belt and slide on the base plate as the belt moves, passing through filling, sealing, and inspection stations in sequence to complete the liquid filling operation.

[0003] In existing high-speed filling production lines, multiple push plates are spaced along the conveyor belt surface to position and push the filling barrels. Adjacent push plates form a station for accommodating a single filling barrel. The rotating conveyor belt moves the filling barrels. To maximize efficiency, a high-flow-rate filling mode is often used. Towards the end of filling, when the liquid level in the container is nearly full, the high-speed falling liquid column violently impacts the already raised liquid level, causing significant liquid splashing. The splashed thermal management liquid spills onto the outside of the filling barrels, the conveyor belt surface, and the surrounding area, contaminating the filling area and conveyor structure. This residual liquid not only attracts dust and forms stains but may also corrode precision components of the conveyor mechanism due to its chemical properties, or cause slippage between the conveyor belt and the drive wheels, affecting conveying stability. Furthermore, frequent cleaning and maintenance increase production downtime and labor costs, posing a threat to the cleanliness of the production environment and operational safety. Simultaneously, this splashing phenomenon can cause some splashed liquid to be included in the total filling volume by the metering system, resulting in insufficient actual filling volume and affecting the accuracy of product metering. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a filling and conveying structure for thermal management fluid in new energy vehicles, so as to solve the technical problem that the existing filling and conveying structure cannot protect the thermal management fluid from splashing during filling.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filling and conveying structure for thermal management fluid in new energy vehicles, comprising a conveyor belt, rotatable limiting plates on both sides of the conveyor belt, first slide rails on both sides of the limiting plates, a slidable first rack mounted on each first slide rail, a pushing device that can cooperate with the limiting plate on each first rack, a reset device for driving the first rack to reset on both sides of the conveyor belt, and a shielding and collecting device for protecting and collecting splashed thermal management fluid during the filling operation on both sides of the conveyor belt, wherein two shielding and collecting devices can respectively mesh with two first racks.

[0006] In this solution, after the rotatable limiting plate rotates 90°, it can automatically contact and interact with the pushing device on the first rack under the drive of the conveyor belt. No additional sensors or electronic control signals are required. After triggering, the pushing device transmits the kinetic energy of the conveyor belt through the linear motion of the first rack. The motion of the first rack directly drives the shielding and protective device that meshes with it to precisely deploy at the filling station, thereby achieving immediate and effective protection against splashed liquid. This process is completed purely mechanically, with rapid response and high reliability. After the filling operation is completed, the reset device automatically pulls the first rack and its associated pushing device back to the initial position through elastic restoring force, preparing for the next work cycle.

[0007] Furthermore, both of the aforementioned shielding and protective devices include a first mounting frame, which is fixedly connected to the side of the conveyor belt. A rotatable shaft is provided on the first mounting frame, and a first gear that can mesh with the first rack is fixedly connected below the shaft. A second gear is fixedly connected above the shaft. A shielding and protective unit for protecting and collecting the heat management liquid splashed during canning is provided on the side wall of the first mounting frame. A connecting rod is provided on the shielding and protective unit, and multiple sets of cooperating shielding units are fixedly provided on the side of the connecting rod away from the shielding and protective unit for moving with the shielding and protective unit and covering multiple canning barrels to achieve coordinated protection and splash collection for multiple workstations.

[0008] In this solution, when the first rack moves, the linear motion is converted into the rotational motion of the shaft through the first gear meshing with it. The second gear at the upper end of the shaft then transmits the power to the shielding and protection unit, realizing the direction conversion and distance increase effect of power transmission. The connecting rod rigidly connects the shielding and protection unit with multiple sets of cooperating shielding units to form a linkage mechanism. This allows a single power input to synchronously drive the action of multiple protection units, ensuring that multiple filling stations can obtain protective coverage at the same time.

[0009] Furthermore, the shielding and protection unit includes a second slide rail, which is disposed on the first mounting bracket. A second rack that meshes with the second gear is slidably disposed on the second slide rail. The second rack is fixedly connected to the connecting rod above it. A first semi-circular shielding plate is fixedly connected to the second rack. A first collection groove is provided on the side wall of the first semi-circular shielding plate.

[0010] In this design, the second slide rail provides precise linear motion guidance for the second rack, ensuring a stable motion trajectory when meshing with the second gear. The second rack converts the rotational motion of the second gear into precise linear displacement, and through the connecting rod fixed above it, it achieves linkage control with multiple sets of cooperating shielding units. The first semi-circular shielding plate installed at the front end of the second rack can be precisely moved to the top of the can, forming a physical barrier above the can. The first collection groove opened on the side wall of the first semi-circular shielding plate realizes the function of collecting and guiding the splashed liquid, further avoiding secondary splashing of liquid and ensuring the cleanliness of the production environment.

[0011] Furthermore, each of the multiple sets of the cooperating shielding units includes a third slide rail, which is located on the side of the conveyor belt. A slidable slider is provided on the third slide rail, and the slider is fixedly connected to the connecting rod above. A second semi-circular shielding plate is fixedly connected to the slider, and a second collection groove is provided on the side wall of the second semi-circular shielding plate.

[0012] In this solution, the third slide rail provides a stable linear motion track for the slider, ensuring that its motion trajectory is precise and controllable. The slider achieves mechanical linkage with the shielding and protection unit through the fixed connection between the upper part and the connecting rod, enabling multiple shielding and protection devices at multiple workstations to operate synchronously. The second semi-circular shield fixed at the front end of the slider can be accurately moved to the top of the corresponding workstation's filling barrel to prevent heat splashing during filling.

[0013] Furthermore, both of the aforementioned pushing devices include torsion springs, which are disposed on the first rack, and a mating plate that can contact the limiting plate is fixedly connected to the torsion springs.

[0014] In this scheme, during the triggering phase, when the limiting plate moves with the conveyor belt and contacts the mating plate, the initial preload of the torsion spring ensures that the mating plate and the limiting plate maintain stable surface contact and effectively transmits the driving force to the first rack. At this time, the torsion spring only produces a small elastic deformation, and the movement trajectory of the torsion spring is manifested as a small rotation around the axis. When the first rack moves to the end of the first slide rail stroke and the limiting plate still needs to move forward, the leading edge of the limiting plate begins to press against the mating plate, forcing it to overcome the preload torque of the torsion spring and begin to rotate significantly around the axis of the torsion spring from a stable contact position. During this process, the contact point between the mating plate and the limiting plate continues to slide, and the contact state smoothly transitions from surface contact to line contact, and finally to point contact. When the limiting plate completely disengages, the elastic potential energy stored in the torsion spring drives the mating plate to move in the opposite direction along the original rotation trajectory, automatically resetting to the initial posture and preparing for the next triggering cycle.

[0015] Furthermore, both of the reset devices include a sleeve, which is fixedly connected to the conveyor belt. A slidable pull rod is provided inside the sleeve, and one end of the pull rod away from the sleeve is fixedly connected to the first rack. A spring is provided inside the sleeve, with one end of the spring fixedly connected to the sleeve and the other end of the spring fixedly connected to the pull rod.

[0016] In this scheme, when the force that pushes the mating plate and thus the first rack moves under the drive of the conveyor belt is removed (i.e., after the limit plate and the mating plate are no longer in contact), the stretched spring immediately releases its stored elastic potential energy and applies a continuous and constant-direction restoring force to the first rack through the pull rod, driving it to return to the initial position accurately and smoothly.

[0017] The working principle and beneficial effects of this solution are as follows: According to the filling quantity, the operator rotates the limiting plate on the push plate corresponding to the last filling barrel entering the station by 90° and sets it vertically. After the conveyor belt starts, when the limiting plate moves to contact the mating plate of the pushing device, it pushes the first rack to move under the pre-tension of the torsion spring. Then, through the transmission of the first gear, the rotating shaft and the second gear, it drives the second rack and the first semi-circular baffle on it to close towards the center of the filling barrel. At the same time, the connecting rod drives multiple sets of second semi-circular baffles to close synchronously. When all the semi-circular baffles are closed into a complete circle, the conveyor belt stops rotating and filling begins. The splashed liquid is blocked by the inner wall of the semi-circular baffle and is collected by the first collection groove and the second collection groove on it. After filling is completed, the conveyor belt restarts, the limiting plate overcomes the pre-tension of the torsion spring and disengages from the mating plate, and the spring pulls the first rack to reset. This structure effectively solves the technical problem that the existing filling conveyor structure cannot protect against splashed heat management liquid during filling.

[0021] The following detailed description illustrates the specific implementation method: Example

[0022] like Figures 1 to 4As shown, a filling and conveying structure for thermal management fluid in new energy vehicles is disclosed, including a conveyor belt 1, two damping shafts 2, two limiting plates 3, two first slide rails 4, two first racks 5, two pushing devices, two resetting devices, and two shielding and protective devices. Each push plate on the conveyor belt 1 has a damping shaft 2 on both sides of its lateral side. Each damping shaft 2 is movably connected to a limiting plate 3. First slide rails 4 are symmetrically arranged on the fixed frames on both sides of the conveyor belt 1. Each first slide rail 4 is equipped with a slidable first rack 5, and each of the two first racks 5 is equipped with... The conveyor belt 1 is equipped with two pushing devices, which can contact the limiting plate 3 on the same side and push the first rack 5 to move. Both sides of the conveyor belt 1 are equipped with reset devices. The two reset devices are used to drive the first rack 5 on the same side to reset to the initial position after the pushing action is completed. Both sides of the conveyor belt 1 are symmetrically equipped with a shielding and protective device. The two shielding and protective devices can mesh with the two first racks 5 respectively. The shielding and protective devices are located below the filling mechanism. The shielding and protective devices are used to effectively block and collect the heat management liquid that may splash out during the filling operation.

[0023] like Figure 2 As shown, both shielding and protective devices include a first mounting frame 6, a rotating shaft 7, a first gear 8, a second gear 9, a second mounting frame 10, a shielding and protective unit, a connecting rod 27, and multiple sets of cooperating shielding units. The first mounting frame 6 is laterally fixedly connected to the conveyor belt 1. The rotating shaft 7 is rotatably connected to the first mounting frame 6. The lower end of the rotating shaft 7 is fixedly connected to the first gear 8, which can mesh with the first rack 5 for transmission. The upper end of the rotating shaft 7 is fixedly connected to the second gear 9. The side of the first mounting frame 6 closest to the first slide rail 4 is fixedly connected to the second gear 9. Mounting frame 10, the second mounting frame 10 is provided with a shielding and protection unit, the shielding and protection unit meshes with the second gear 9, the shielding and protection unit is used to move synchronously to the top of the canning barrel to shield and collect the heat management liquid splashed from the canning barrel. The shielding and protection unit is provided with a connecting rod 27, and multiple sets of cooperating shielding units are provided on the side of the connecting rod 27 away from the shielding and protection unit. The multiple sets of cooperating shielding units are used to move synchronously with the shielding and protection unit through the connecting rod 27 to cover multiple canning barrels, so as to realize the coordinated protection and splash collection of multiple workstations.

[0024] like Figure 3 As shown, the shielding and protection unit includes a second slide rail 11, a second rack 12, and a first semi-circular shield 13. The second slide rail 11 is fixedly connected to the second mounting bracket 10. The second rack 12 is slidably arranged on the second slide rail 11. The second rack 12 meshes with the second gear 9 for transmission. The upper end face of the second rack 12 is fixedly connected to the connecting rod 27. The first semi-circular shield 13 is fixedly connected to one end of the second rack 12 near the filling mechanism. A first collection groove 14 is opened on the side of the first semi-circular shield 13 away from the second rack 12. The diameter of the first semi-circular shield 13 is the same as the inner wall diameter of the filling barrel.

[0025] like Figure 2 As shown, each of the multiple sets of shielding units includes a third mounting bracket 15, a third slide rail 16, a slider 17, and a second semi-circular shielding plate 18. The conveyor belt 1 is laterally fixedly connected to the third mounting bracket 15. The third slide rail 16 is fixedly connected to the third mounting bracket 15. The slider 17 is slidably mounted on the third slide rail 16. The upper end face of the slider 17 is fixedly connected to the connecting rod 27. The end of the slider 17 near the filling mechanism is fixedly connected to the second semi-circular shielding plate 18. The side of the second semi-circular shielding plate 18 away from the slider 17 has a second collection groove 19. The diameter of the second semi-circular shielding plate 18 is the same as the inner wall diameter of the filling barrel.

[0026] like Figure 1 As shown, both pushing devices include an arc-shaped mounting frame 20, a torsion spring 21, and a mating plate 22. The arc-shaped mounting frame 20 is fixedly connected to the upper end face of the first rack 5. The torsion spring 21 is fixedly connected to the inner wall of the arc-shaped mounting frame 20. The rotating end of the torsion spring 21 is fixedly connected to the mating plate 22. The mating plate 22 can contact the limiting plate 3. When the mating plate 22 contacts the limiting plate 3 under the pre-tightening force of the torsion spring 21, the limiting plate 3 then drives the first rack 5 to move through the mating plate 22.

[0027] like Figure 4 As shown, both reset devices include a mounting block 23, a sleeve 24, a spring 25, and a pull rod 26. The mounting block 23 is fixedly connected to the side of the conveyor belt 1. The sleeve 24 is fixedly connected to the mounting block 23. The pull rod 26 is slidably connected inside the sleeve 24. The end of the pull rod 26 away from the sleeve 24 is fixedly connected to the first rack 5. The spring 25 is provided inside the sleeve 24. One end of the spring 25 is fixedly connected to the sleeve 24, and the other end of the spring 25 is fixedly connected to the pull rod 26. The reset force provided by the spring 25 is less than the preload force of the torsion spring 21 acting on the mating plate 22 in the pushing device.

[0028] In practice When the heat management fluid filling begins, the operator places the cans between the push plates of the conveyor belt 1 and performs initial settings. First, the number of cans to be filled simultaneously by the filling mechanism is determined. Then, the limiting plate 3 on the push plate corresponding to the last can entering the filling mechanism is rotated 90° by the damping shaft 2 to make it perpendicular to the push plate. Next, the conveyor belt 1 is started. Driven by the conveyor belt 1, the cans gradually enter the filling mechanism. When the last can reaches the filling station, the limiting plate 3 on its corresponding push plate is already in a state of pre-rotation of 90°.

[0029] As the conveyor belt 1 continues to move, the limiting plate 3 gradually comes into contact with the mating plate 22 on the torsion spring 21 in the pushing device. Since the preload of the torsion spring 21 is greater than the reset force of the spring 25 in the reset device, the limiting plate 3, under the push of the conveyor belt 1, drives the first rack 5 to move along the first slide rail 4 through the mating plate 22.

[0030] During the movement, the first rack 5 meshes with the first gear 8, which drives the rotating shaft 7 to rotate. The rotating shaft 7 further drives the second gear 9 to rotate. The second gear 9 drives the second rack 12, which is mounted on the second mounting bracket 10 and is in the second slide rail 11, to move towards the center of the can. At the same time, the second rack 12 drives the first semi-circular shield 13 to move towards the center. Since there are two sets of symmetrical shielding and protection units, the first semi-circular shields 13 on both sides move towards the center of the can simultaneously.

[0031] When the second rack 12 moves, it also drives the connecting rod 27 above it to move synchronously. The connecting rod 27 further drives all the sliders 17 installed on the third slide rail 16 on the third mounting frame 15 to move, so that the second semi-circular baffle 18 at the front end of each slider 17 also moves towards the center of the corresponding can. When the first semi-circular baffles 13 on both sides close to form a complete circle, and all the second semi-circular baffles 18 also close to form a complete circle, the conveyor belt 1 stops running and the filling mechanism starts the filling operation.

[0032] During the filling process, the heat management liquid splashed up is blocked by the inner wall of the first semi-circular baffle 13 and collected through the first collection trough 14 opened on the plate. At the same time, each of the second semi-circular baffles 18 and the second collection trough 19 also block and collect the liquid splashed up from other cans being filled at the same time.

[0033] After filling is completed, the conveyor belt 1 restarts. At this time, the limiting plate 3 still maintains contact with the mating plate 22, but since the first rack 5 has moved to the end of the stroke of the first slide rail 4, the mating plate 22 stops moving, while the limiting plate 3 on the conveyor belt 1 continues to move forward, beginning to overcome the preload of the torsion spring 21, forcing the mating plate 22 to rotate around the central axis of the torsion spring 21. During this process, the contact area between the limiting plate 3 and the mating plate 22 continuously decreases, gradually transitioning from an initial large-area surface contact to a line contact, and further narrowing to a point contact. As the relative movement continues, this point contact position slides along the edge of the mating plate 22 toward its end, causing the resistance arm of the torsion spring 21 to continuously shorten. Finally, the edge of the limiting plate 3 completely slides past the end of the mating plate 22, and the two completely disengage. At this time, the stretched spring 25 in the reset device begins to release the reset force, driving the first rack 5 to slide back to its initial position along the first slide rail 4 via the pull rod 26.

[0034] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
