Description
Technical Field
[0001] The utility model relates to the technical field of new energy vehicle structures, in particular to a new energy vehicle chassis suspension with a safety monitoring structure. Background Art
[0002] Automobile suspension is an important component for ensuring ride comfort. At the same time, as a force transmission component connecting the vehicle frame or body with the axle or wheel, it is also an important component for ensuring vehicle driving safety.
[0003] Due to the reasons of battery life, the addition of batteries to new energy vehicles also leads to an increase in vehicle weight and an increase in the load on the control arms. Moreover, as the number of control arms in the vehicle increases, the risk of control arm failure increases.
[0004] When one of the control arms of the chassis suspension bends and fails, it is not easy for the user to notice. During intense driving or on harsh roads, major vehicle accidents such as control arm breakage are prone to occur.
[0005] In addition, new energy vehicles require less maintenance than fuel vehicles, and many customers rarely perform routine inspections. Therefore, the safety of chassis structural parts becomes an issue that affects the safety of customers' use of the vehicle. Utility Model Content
[0006] In view of the above problems, the purpose of the present utility model is to provide a new energy vehicle chassis suspension with a safety monitoring structure to solve the problem in the prior art that after one of the control arms of the chassis suspension fails in bending, it is not easy for the user to notice, and the control arm is prone to breakage during intense driving or on harsh roads. In addition, the number of maintenance times for new energy vehicles is reduced, and many customers rarely perform routine inspections, making it difficult to discover hidden dangers.
[0007] The utility model provides a new energy vehicle chassis suspension with a safety monitoring structure, comprising a suspension body, an assembly hole and a detection part;
[0008] The suspension body is provided with an assembly area;
[0009] The assembly hole is opened on the assembly area of the suspension body;
[0010] The detection component includes a detection end and a signal output end. The detection end of the detection component is arranged in the assembly hole, and the signal output end is connected to the detection end by signal.
[0011] Compared to existing technologies, the above-mentioned technical solution has the following advantages: by providing assembly holes and detection components on the suspension body, the safety status signal of the structural component can be transmitted to the central control screen based on the status of the detection component, whether the suspension body is in normal or damaged deformation state. This reminds the operator to avoid driving that causes significant impact on the suspension body. Alternatively, when the suspension body is damaged, the detection component continuously triggers the transmission signal, forcing the driver to drive at a low speed to a repair shop to replace the control arm, thereby improving vehicle safety. Furthermore, the design of a safety monitoring system on low-value structural components allows low-value parts to absorb energy and damage first in vehicle accidents, protecting high-value parts and saving users' vehicle costs.
[0012] As a preferred embodiment of the present application, a signal line is further included, one end of which is connected to the signal output end of the detection member. By providing the signal line, the signal of the detection member on the assembly hole is easily transmitted to the vehicle and connected to the interface.
[0013] As a preferred embodiment of the present application, a wire fixing point is further included, wherein the wire fixing point is provided on the suspension body, and the signal wire is assembled on the signal wire fixing point. By providing the wire fixing point, it is convenient to position and assemble the signal wire.
[0014] As a preferred embodiment of the present application, the detection end of the detection member is a contact switch, which is relatively arranged on both sides of the assembly hole, with a spacing between the contact switches on both sides. By providing the contact switches, it is convenient to detect the detection member based on the spacing between the contact switches.
[0015] As a preferred embodiment of the present application, the assembly hole is a circular or polygonal structure.
[0016] As a preferred embodiment of the present application, the number of assembly holes of the suspension body is one or more. By setting the number of assembly holes of the suspension body to one or more, multi-point detection is facilitated, ensuring that the suspension body can be inspected at multiple points even if there are multiple fragile structures.
[0017] As a preferred embodiment of the present application, a signal interface is further included, and the signal interface is provided at the end of the signal line. By providing the signal interface, it is convenient to connect the signal lines.
[0018] As a preferred embodiment of the present application, the assembly area of the suspension body is arranged in the middle of the plate structure of the suspension body or on a reserved bend. By arranging the assembly area of the suspension body in the middle of the plate structure of the suspension body or on a reserved bend, it is convenient to test the vulnerable parts of the suspension body.
[0019] As a preferred embodiment of the present application, the diameter of the assembly hole is less than 12 mm.
[0020] As a preferred embodiment of the present application, the distance between the contact switches arranged on two sides of the assembly hole is 1 mm. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Please also refer to Figures 1 to 5 , the inventor provides a new energy vehicle chassis suspension with a safety monitoring structure, including a suspension body 10, an assembly hole 20 and a detection member 30;
[0043] The suspension body 10 is provided with an assembly area;
[0044] The assembly hole 20 is opened on the assembly area of the suspension body 10;
[0045] The detection member 30 includes a detection end and a signal output end. The detection end of the detection member is arranged in the assembly hole 20, and the signal output end is connected to the detection end by signal.
[0046] According to the above structure, during the actual use of the new energy vehicle chassis suspension with a safety monitoring structure, the suspension body 10 is assembled on the vehicle chassis, and the detection part 30 is assembled in the assembly hole 20 of the suspension body 10. The assembly hole 20 is set in the assembly area of the suspension body 10, and the assembly area is selected from the vulnerable area of the suspension body 10. The detection part 30 is connected to the on-board computer or the central control for signal connection. During driving, when the suspension body 10 is impacted by external force and the assembly area is impacted, causing the assembly hole 20 to deform, the detection part 30 reaches the threshold and is triggered, sending a signal to the on-board computer or the central control screen to inform the operator that the vehicle has been subjected to a strong impact, or when the detection part 30 is continuously triggered, it informs the operator that the suspension body 10 is damaged. This allows the operator to slow down, stop for inspection, or go to the vehicle maintenance department for repair.
[0047] By providing assembly holes 20 and detection components 30 on the suspension body 10, the safety status signal of the structural component can be transmitted to the central control screen based on the status of the detection component 30, whether the suspension body 10 is in a normal or damaged deformation state. This reminds the operator to avoid driving in a manner that causes significant impact on the suspension body 10. Alternatively, when the suspension body 10 is damaged, the detection component 30 continuously triggers the transmission signal, forcing the driver to drive at a low speed to a repair shop to replace the control arm, thereby improving vehicle safety. Furthermore, by designing a safety monitoring system on low-value structural components, low-value parts absorb energy first in vehicle accidents and are damaged first, protecting high-value parts and saving users' vehicle costs.
[0048] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, a signal line 40 is further included, one end of which is connected to the signal output end of the detection member 30. By providing the signal line 40, the signal of the detection member 30 on the assembly hole 20 is easily transmitted to the vehicle and connected to the interface.
[0049] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, it further includes a line fixing point, which is set on the suspension body 10, and the signal line 40 is assembled on the signal line 40 fixing point. By setting the line fixing point, it is convenient to position and assemble the signal line 40.
[0050] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the detection end of the detection member is a contact switch, which is arranged on both sides of the assembly hole 20, with a distance between the contact switches on both sides. By providing the contact switches, the detection of the detection member 30 is facilitated by the distance between the contact switches.
[0051] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the assembly hole 20 is a circular or polygonal structure.
[0052] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the number of the assembly holes 20 of the suspension body 10 is one or more. By setting the number of the assembly holes 20 of the suspension body 10 to one or more, multi-point inspection is facilitated, ensuring that the suspension body 10 can be inspected at multiple points even if there are multiple fragile structures.
[0053] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the device further includes a signal interface 41, which is provided at the end of the signal line 40. By providing the signal interface 41, the signal line 40 is easily docked.
[0054] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the assembly area of the suspension body 10 is set in the middle of the plate structure of the suspension body 10 or on the reserved bend. By setting the assembly area of the suspension body 10 in the middle of the plate structure of the suspension body 10 or on the reserved bend, it is convenient to detect the vulnerable parts of the suspension body 10.
[0055] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the diameter of the assembly hole 20 is less than 12 mm.
[0056] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the spacing between the contact switches relatively arranged on both sides of the assembly hole 20 is 1mm. Setting the spacing of 1mm is out of safety considerations for the suspension body 10 and is a requirement of current design experience. 1mm is a spacing that the driver and the customer cannot perceive and judge. The contact switch is needed to trigger a reminder to ensure that the driver and the customer replace it in time to eliminate safety hazards. When the suspension body 10 collapses by more than 1mm, there is a certain probability that the suspension body 10 will crack locally, affecting the safety of vehicle use. On the contrary, if the suspension body 10 collapses by ≤1mm, the normal and safe use of the vehicle can be guaranteed.
[0057] In the above embodiment, the vulnerable area of the suspension body is the area of the suspension body 10 where the assembly hole 20 is located. The assembly hole is the designated weak point of the suspension body 10 designed by the engineer, and is also the assembly point of the contact switch, which is used to accurately monitor the health status of the suspension body 10.
[0058] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
