Description

Technical Field

[0001] This application relates to the field of vehicle safety technology, specifically to a throwing device and a vehicle. Background Technology

[0002] In vehicles that use flammable refrigerants (such as R290) as the cooling medium, in order to prevent refrigerant leakage and accumulation after a collision from causing explosions or deflagrations and secondary injuries, the refrigerant module must be detached at the moment of the collision (that is, the connection between the refrigerant module and the vehicle frame is broken).

[0003] In vehicles using related technologies, shear clamps with mechanically weak points are typically used to achieve ejection fracture. This relies on the impact force generated by the collision exceeding the shear clamp's ultimate load to trigger shear fracture. However, due to the complexity and uncertainty of actual collision scenarios, the magnitude and direction of the impact force are unpredictable and may not meet the mechanical conditions necessary for the structure to trigger ejection fracture. This can lead to ejection failure, affecting the reliability of the ejection structure and consequently reducing the vehicle's safety performance. Summary of the Invention

They are only for the purpose of simplifying the description of this application and do not indicate that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. In other words, they should not be construed as limitations on this application.

[0030] In the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "linking," "fixing," "setting," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can also refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0031] In the description of this application, unless otherwise expressly defined, the terms "above," "over," "on top of," "below," "below," "under," or "below" for "first feature over second feature" can refer to the first and second features being in direct contact, or to the first and second features being in indirect contact through an intermediate medium.

[0032] In vehicles that use flammable refrigerants (such as R290) as the cooling medium, in order to prevent refrigerant leakage and accumulation after a collision from causing explosions or deflagrations and secondary injuries, the refrigerant module must be detached at the moment of the collision (that is, the connection between the refrigerant module and the vehicle frame is broken).

[0033] In vehicles using related technologies, shear clamps with mechanically weak points are typically used to achieve ejection fracture. This relies on the impact force generated by the collision exceeding the shear clamp's ultimate load to trigger shear fracture. However, due to the complexity and uncertainty of actual collision scenarios, the magnitude and direction of the impact force are unpredictable and may not meet the mechanical conditions necessary for the structure to trigger ejection fracture. This can lead to ejection failure, affecting the reliability of the ejection structure and consequently reducing the vehicle's safety performance.

[0034] To address the aforementioned problems, some embodiments of this application provide a refrigerant ejection device and a vehicle. The ejection device includes a ejection structure comprising a first ejection segment, which connects the vehicle frame and the refrigerant module. Functional components, fixed relative to the ejection structure, are configured to cause the first ejection segment to disconnect. This solution eliminates the passive dependence of the refrigerant module ejection process on collision impact forces, thereby achieving active and controllable ejection, improving vehicle safety and the flexibility of the ejection function response.

[0035] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0036] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of vehicle 1 provided in some embodiments of this application. Some embodiments of this application do not limit the type of vehicle 1. For example, vehicle 1 can be a sedan, a sports utility vehicle (SUV), a multi-purpose vehicle (MPV), a van (VAN), etc.

[0037] Vehicle 1 includes a frame 20, and a powertrain, chassis assembly, and electronic information system mounted on the frame 20. The powertrain is used to generate and output power; the chassis assembly is used to ensure stable handling, safe braking, and smooth driving of the vehicle; and the electronic information system is used to provide information interaction services for the driver and passengers.

[0038] The frame 20 has multiple doors 80. A portion of the frame 20 encloses to form a driver's and passenger compartment. The frame 20 also has multiple doorways 21 connecting to the driver's and passenger compartment.

[0039] Multiple doors 80 are hinged to the frame 20. In other words, each door 80 is pivotable relative to the frame 20 to switch between an open and closed state. In the open state, the free end of the door 80 is away from the frame 20, allowing passengers or the driver to enter and exit the passenger compartment through the doorway 21. In the closed state, the door 80 blocks the doorway 21, thus protecting the passenger compartment and ensuring the safety of the user's person and property.

[0040] Please see Figure 2 , Figure 2 for Figure 1 The diagram shows the structural design of the vehicle frame, refrigerant module, and break-off device 10. Vehicle 1 also includes a refrigerant module 30 and a break-off device 10. The refrigerant module 30 is used in the vehicle's thermal management system. The break-off device 10 connects the frame 20 and the refrigerant module 30. In other words, the refrigerant module 30 is connected to the frame 20 via the break-off device 10.

[0041] The refrigerant module 30 is filled with refrigerant, which in some embodiments may be flammable R290 (propane). The ejection device 10 is used to: actively or passively disconnect the mechanical connection between the refrigerant module 30 and the frame 20 when the vehicle 1 experiences a specific dangerous operating condition, so that the refrigerant module 30 can detach from the vehicle body, thereby avoiding or mitigating the leakage, accumulation, and secondary hazards caused by the flammable refrigerant due to the impact and rupture of the refrigerant module 30.

[0042] The break-off device 10 includes a break-off structure 11 and a functional component 12. The break-off structure 11 is used to connect the frame 20 and the refrigerant module 30, and the break-off structure 11 includes a first break-off segment 111; the functional component 12 is fixed relative to the break-off structure 11, and the functional component 12 operates to disconnect the first break-off segment 111.

[0043] Specifically, the functional component 12 can be configured to perform a specific task when a trigger signal is received, in order to intervene in the mechanical state of the first throwing segment 111 and ultimately cause the first throwing segment 111 to break.

[0044] Thus, by setting up a break-off structure 11 including a first break-off segment 111 to connect the vehicle frame 20 and the refrigerant module 30, and by using the operation of the functional component 12 to cause the first break-off segment 111 to disconnect, the break-off process of the refrigerant module 30 no longer passively depends on the impact force of the collision, realizing active and controllable break-off, improving the safety of the vehicle 1 and the flexibility of the break-off function response.

[0045] The following section will describe in detail the specific structure and working principle of the throwing device 10 and the vehicle 1, using multiple embodiments.

[0046] In some embodiments, such as Figure 2 As shown, the first break segment 111 is a shape memory alloy part; the functional component 12 includes a heater 121, which is used to heat the first break segment 111 to break the first break segment 111.

[0047] Specifically, when the heater 121 is activated, the heat it generates is transferred to the first break section 111, causing the temperature of the first break section 111 to rise. When the temperature of the first break section 111 reaches or exceeds its own phase transition temperature, the internal stress or shape change of the first break section 111 caused by the phase transition will lead to a decrease in its mechanical strength locally or as a whole, thereby causing it to fracture or break apart, thus achieving the break-off function.

[0048] Thus, by utilizing the material properties of shape memory alloy parts and combining them with heater 121 for precise and rapid local heating, the first break-off segment 111 can undergo a phase change and break (as under electrical signal control), which helps to improve the effectiveness and reliability of the break-off function and reduces the weight of the break-off device 10, thereby avoiding redundancy in the internal structure of the vehicle 1 to a certain extent.

[0049] In some embodiments, such as Figure 2 As shown, the first break section 111 includes: a first part 111a and a second part 111b; a heater 121 is disposed in the first part 111a and is used to heat the first part 111a so that the first break section 111 is broken.

[0050] Thus, by concentrating the heaters 121 in the first part 111a, the temperature of the first part 111a can reach the phase transition temperature and deform before the second part 111b during the heating process. This results in stress concentration between the first part 111a and the second part 111b, causing the first breakage segment 111 to break at that point. This helps to reduce the power requirement of the heaters 121, improve heating efficiency, and to a certain extent ensure the predictability and controllability of the breakage position of the first breakage segment 111.

[0051] In some embodiments, the phase transition temperature of the shape memory alloy part (i.e., the first breakage segment 111) is greater than or equal to 75°C and less than or equal to 92°C. For example, the phase transition temperature of the shape memory alloy part is 75°C, 80°C, 85°C, 88°C, 90°C, or 92°C.

[0052] It is understandable that if the phase change temperature of the first ejection section 111 is too low (e.g., below 75°C), the vehicle 1 may be falsely triggered during normal driving or in high-temperature environments (e.g., the engine compartment heats up after being exposed to the sun in summer); if the phase change temperature of the first ejection section 111 is too high (e.g., above 92°C), the heater 121 will require more time and more energy to bring the first ejection section 111 to the phase change temperature, affecting the ejection response speed.

[0053] Therefore, by setting the phase change temperature of the first break section 111 within the range of greater than or equal to 75°C and less than or equal to 92°C, the possibility of accidental breakage caused by ambient temperature fluctuations can be effectively reduced. Furthermore, when breakage is required, it is beneficial to increase the speed at which the heater 121 heats the first break section 111 to the phase change temperature, thus ensuring a rapid response capability in emergency situations.

[0054] In some embodiments, the shape memory alloy part (i.e., the first fracture segment 111) is made of nickel-titanium-copper shape memory alloy. It is understood that the control of the phase transformation temperature of the shape memory alloy part depends on the material of the shape memory alloy part. The phase transformation temperature of nickel-titanium-copper shape memory alloy is between 88°C and 92°C, and it can generate a deformation displacement of not less than 6 mm during the phase transformation, which can provide sufficient fracture driving force.

[0055] In other embodiments, the shape memory alloy part (i.e., the first break-off segment 111) is made of copper-nickel shape memory alloy. Copper-nickel shape memory alloy has low material cost, low processing difficulty, a phase transition temperature of about 75°C to 85°C, and a phase transformation displacement of 4 mm, making it suitable for scenarios with relatively low triggering force requirements.

[0056] In some embodiments, such as Figure 2As shown, heater 121 is a heating wire wound around the outer periphery of the first throwing section 111. This helps reduce the manufacturing cost of the throwing device 10 and facilitates installation and maintenance. Furthermore, the heat generated by the heating wire after being energized can directly act on the outer surface of the first throwing section 111, achieving rapid heating.

[0057] In some examples, a thermally conductive insulating material is coated between the heating wire and the surface of the first break section 111 to improve thermal contact efficiency and provide electrical insulation.

[0058] Please see Figure 3 , Figure 3 This is a schematic diagram of the frame, refrigerant module, and break-off device in some other embodiments of this application.

[0059] The first fragmented section 111 is hollow inside, and its inner peripheral wall is provided with reinforcing ribs; the heater 121 is disposed inside the first fragmented section 111. Specifically, the reinforcing ribs extend along the axial and / or circumferential direction of the first fragmented section 111.

[0060] It is understandable that the reinforcing ribs can enhance the bending and torsional stiffness of the hollow structure of the first segment 111, compensate for the strength loss that the hollow structure may cause, and ensure that the first segment 111 can stably and reliably transmit the connecting load during normal vehicle operation.

[0061] Thus, by placing the heater 121 in the internal cavity of the first break section 111, the heater 121 is encased in shape memory alloy material, which helps to shorten the heat transfer path and improve heating efficiency. Furthermore, the shape memory alloy provides physical protection for the heater 121, thereby preventing the heater 121 from being affected by external moisture, oil, or mechanical impacts, and improving the environmental tolerance and service life of the heater 121.

[0062] Please see Figure 4 , Figure 4 This is a schematic diagram of the frame, refrigerant module, and throwing device in other embodiments of this application. Functional component 12 includes a cutting element 122 and a driving element 123. The driving element 123 is fixed relative to the throwing structure 11. The driving element 123 is connected to the cutting element 122 and is used to drive the cutting element 122 to move towards the first throwing segment 111 to cut the first throwing segment 111. Thus, by driving the cutting element 122 to physically cut the first throwing segment 111 through the driving element 123, the reliability of the throwing function is improved, and the probability of throwing failure is reduced.

[0063] In some embodiments, such as Figure 4As shown, the driving component 123 includes a hydraulic pump 1231 and a hydraulic cylinder 1232, and the cutting component 122 is a push rod; the hydraulic pump 1231 is connected to the rodless chamber 1233 of the hydraulic cylinder 1232; the hydraulic pump 1231 is used to pump hydraulic oil to the rodless chamber 1233 to drive the push rod to move toward the direction close to the first throwing section 111.

[0064] Specifically, when the cutting needs to be performed, the hydraulic pump 1231 starts and pumps hydraulic oil into the rodless chamber 1233. The increase in oil pressure in the rodless chamber 1233 generates hydraulic pressure, which pushes the push rod (i.e. the cutting element 122) to extend outward and move towards the first cutting section 111.

[0065] Understandably, the hydraulic system can generate extremely high output pressure, ensuring that the push rod has the thrust required to cut off the first throwing segment 111. At the same time, the pressure of the hydraulic system can be precisely controlled through the flow rate of the hydraulic pump 1231 and the pressure relief valve, making the cutting force stable and highly reliable.

[0066] In some embodiments, such as Figures 2 to 4 As shown, the break-off structure 11 further includes: two connecting sections 113, one of which is used to connect the frame 20, and the other is used to connect the refrigerant module 30; a first break-off section 111 is located between the two connecting sections 113, and at least one end of the first break-off section 111 is connected to an adjacent connecting section 113 through a second break-off section 112 along the arrangement direction of the two connecting sections 113; the ultimate load of the second break-off section 112 is less than the ultimate load of the connecting section 113, and less than the ultimate load of the first break-off section 111. It should be noted that the ultimate load mentioned above refers to the maximum external force that the component can withstand before failure (such as yielding or fracture).

[0067] Thus, when the active ejection system (i.e., the first ejection segment 111 and the functional component 12) is working normally, the functional component 12 disconnects the first ejection segment 111, completing the active ejection. When the active ejection system fails due to severe collision or other reasons, the impact force generated by the collision can be transmitted to the second ejection segment 112 through the connecting segment 113. In this case, because the ultimate load of the second ejection segment 112 is low, the second ejection segment 112 will first undergo mechanical shearing or tensile fracture, thereby achieving the passive ejection of the refrigerant module 30. In this way, by combining passive and active ejection, the reliability and effectiveness of the ejection device 10 can be further improved, thereby enhancing the safety performance of the vehicle 1.

[0068] In some embodiments, such as Figures 2 to 4 As shown, the equivalent diameter of the second break segment 112 is smaller than the equivalent diameter of the connecting segment 113. It should be noted that the equivalent diameter refers to the diameter of a circle with the same cross-sectional area as the component.

[0069] Thus, by making the equivalent diameter of the second throwing segment 112 smaller than the equivalent diameter of the connecting segment 113, the ultimate load of the second throwing segment 112 can be directly reduced, thereby enabling precise control of the trigger threshold of the second throwing segment 112.

[0070] In some embodiments, the first break segment 111 and the second break segment 112 can be constructed as a single integral part, with the end of the integral part having an external or internal thread structure. Correspondingly, the end of the connecting segment 113 has a matching internal or external thread. Thus, by tightening the threaded connection, a fixed connection between the integral part and the connecting segment 113 can be achieved.

[0071] Please see Figure 5 , Figure 5 for Figure 1 The diagram shows a block diagram of the vehicle. Vehicle 1 also includes an electronic control system 40 and an acceleration sensor 50. The acceleration sensor 50 is mounted on the frame 20. The electronic control system 40 is communicatively connected to both the acceleration sensor 50 and the functional component 12; the electronic control system 40 is configured to control the functional component 12 to activate based on the acceleration information detected by the acceleration sensor 50, thereby causing the first ejection segment 111 to disconnect.

[0072] Specifically, the acceleration sensor 50 can detect the longitudinal, lateral, or vertical acceleration experienced by vehicle 1 during driving in real time. The electronic control system 40 internally stores or presets one or more acceleration thresholds. These acceleration thresholds correspond to the critical conditions for determining that a vehicle collision has occurred. Based on this, the electronic control system 40 can continuously receive acceleration information from the acceleration sensor 50, and when the acceleration information reaches the acceleration threshold, it determines that a collision has occurred in vehicle 1 and requires active ejection. In this case, the electronic control system 40 generates and issues a trigger command to control the functional component 12 to start. If the functional component 12 is a heater 121, the electronic control system 40 can control the relay 121 to be energized and heated; if the functional component 12 is a hydraulic system, the command is to start the hydraulic pump so that the push rod cuts off the first ejection segment 111.

[0073] This allows vehicle 1 to respond quickly and automatically to collisions without human intervention, which helps improve the timeliness and automation of the active ejection function.

[0074] In some embodiments, such as Figure 5 As shown, vehicle 1 also includes a pressure sensor 60, which is located within the refrigerant module 30 and is used to detect the refrigerant pressure within the refrigerant module 30. The electronic control system 40 is communicatively connected to both the pressure sensor 60 and the functional component 12; the electronic control system 40 is configured to control the functional component 12 to activate based on the refrigerant pressure information detected by the pressure sensor 60, thereby disconnecting the first break section 111.

[0075] For example, when the pressure sensor 60 detects that the refrigerant pressure drops by more than 0.1 MPa within a certain period of time (e.g., per minute), the electronic control system 40 can determine that the refrigerant in the refrigerant module 30 is leaking and needs to perform active jettison. In this case, the electronic control system 40 generates and issues a trigger command to activate the control function component 12, thereby disconnecting the first jettison segment 111. This allows the vehicle 1 to achieve a rapid and automatic response to a collision accident without manual intervention, which helps to improve the timeliness and automation of the active jettison function.

[0076] In some embodiments, such as Figure 5 As shown, vehicle 1 also includes a ventilation system 70, which is mounted on the frame 20, with its air outlet facing the refrigerant module 30. The ventilation system 70 is communicatively connected to the electronic control system 40. The electronic control system 40 is further configured to activate the ventilation system 70 after the control function component 12 is activated. Thus, the airflow generated by the ventilation system 70 will accelerate the diffusion and dilution of the leaked refrigerant in the external environment, rapidly reducing its concentration to below the flammability limit, thereby further improving vehicle safety.
