Description

Technical Field

[0002] As a new energy industry that has developed in recent years, the hydrogen fuel cell system has encountered many problems during the research and development process, especially in the high-voltage electrical safety design. The insulation performance of the fuel cell has always been an important performance indicator of high-voltage electrical safety, so the insulation design of the fuel cell vehicle system is very important. In the hydrogen fuel cell system, the coolant directly cools the double-stage plate of the stack, which is equivalent to the stack coolant directly contacting the high-voltage conductor in the stack. If the insulation performance of the cooling system flowing through is low to the vehicle body ground, the insulation of the fuel cell vehicle will be significantly reduced. The suspension mounting component of the radiator is a connection point between the vehicle and the fuel cell, so the insulation at the suspension mounting component is very important.

[0003] In order to improve the insulation state of fuel cell vehicles, the prior art discloses a vibration-damping and insulating combined structure for the suspension mounting component of the radiator. Although the prior structure can achieve vibration reduction and basic insulation, in the prior structure, waterproof plastic is arranged on the upper part of the insulating rubber, and there is still a gap between the waterproof plastic and the connecting bracket for connecting the radiator and the connecting bracket for connecting the vehicle body, so that the insulating rubber is still partially exposed. When the insulating rubber meets water, its insulating performance will fail, resulting in the prior structure still having the risk of insulation failure in encountering bad weather such as rainy days, which will affect the normal driving of the fuel cell vehicle and may even cause traffic accidents in serious cases.

[0030] Example 1

[0031] like Figure 1 to Figure 2The figure shows a first embodiment of a radiator insulation device of the utility model, including a first connecting bracket 110 for connecting to the radiator 200, a second connecting bracket 120 for connecting to the vehicle body frame 300, and a bolt assembly 130. The first connecting bracket 110 and the second connecting bracket 120 are respectively connected to the bolt assembly 130, and the connecting ends of the first connecting bracket 110 and the bolt assembly 130 are wrapped with an insulating member 140. The bolt assembly 130 is also sleeved with a first vibration damping member 150 and a second vibration damping member 160, and the first vibration damping member 150 and the second vibration damping member 160 are respectively located at the two ends of the insulating member 140, and the second connecting bracket 120 is abutted against the second vibration damping member 160.

[0032] The connection end of the first connecting bracket 110 with the bolt assembly 130 is wrapped with an insulating member 140, so that there is no direct contact between the first connecting bracket 110 and the bolt assembly 130, so that the radiator insulation device 100 can achieve insulation between the first connecting bracket 110 and the bolt assembly 130 even in rainy weather, thereby achieving insulation at the suspension mounting component; the first vibration damper 150 and the second vibration damper 160 can be used to reduce vibration between the radiator 200 and the vehicle body frame 300, thereby improving the stability of vehicle operation. The utility model provides a radiator insulation device that can be applied to a hydrogen fuel cell radiator of a fuel cell vehicle. Figure 4 As shown, the radiator insulation device 100 is connected to the radiator 200 via a first connection bracket 110 , and the radiator insulation device 100 is connected to the vehicle body frame 300 via a second connection bracket 120 .

[0033] like Figure 1 and Figure 2As shown, the insulating member 140 includes an insulating sleeve 141 and a partition 142. The first connecting bracket 110 is connected to the bolt assembly 130 through the insulating sleeve 141, and the first vibration damper 150 abuts against the insulating sleeve 141; the partition 142 abuts against the first connecting bracket 110, and the partition 142 also abuts against the second vibration damper 160; in this embodiment, the insulating sleeve 141 can contact the partition 142. The arrangement of the insulating sleeve 141 and the partition 142 can facilitate the installation of the insulating member 140 on the first connecting bracket 110. In this embodiment, the bolt assembly 130 is vertically arranged, and the first vibration damper 150 and the second vibration damper 160 are respectively located at the upper end and the lower end of the insulating member 140. The insulating sleeve 141 includes a sleeve portion 1411 and a blocking portion 1412 connected to the upper end of the sleeve portion 1411. The sleeve portion 1411 is sleeved with the bolt assembly 130. The blocking portion 1412 is protruding outward, so that the outer wall of the sleeve portion 1411 and the blocking portion 1412 form a recessed position, the first connecting bracket 110 abuts against the recessed position, the first vibration damper 150 abuts against the upper surface of the blocking portion 1412, and the second vibration damper 160 abuts against the lower surface of the partition 142. In this embodiment, the sleeve portion 1411 and the blocking portion 1412 are integrally formed.

[0034] like Figure 1 and Figure 2 As shown, the lower end of the sleeve portion 1411 extends out of the bolt connection end of the first connecting bracket 110, and the lower end of the sleeve portion 1411 can contact the partition 142; it should be noted that the bolt connection end of the first connecting bracket 110 refers to the end of the first connecting bracket 110 used to connect with the bolt assembly 130. Specifically, in this embodiment, the lower end of the sleeve portion 1411 exceeds the first connecting bracket 110 by at least 1mm, and preferably, the lower end of the sleeve portion 1411 exceeds the first connecting bracket 110 by 2mm; this setting can improve the wrapping of the insulating member 140 and further avoid insulation failure. In this embodiment, the insulating member 140 is a polytetrafluoroethylene insulating member, specifically, the insulating sleeve 141 is a polytetrafluoroethylene insulating sleeve, and the partition 142 is a polytetrafluoroethylene partition. It should be noted that polytetrafluoroethylene has excellent chemical stability, corrosion resistance, sealing, high lubricity and non-stickiness, wear resistance and pressure resistance; it also has good machining performance, smooth surface and non-stickiness, non-flammability, low water absorption, good insulation, and can withstand high pressure. Therefore, the setting of the polytetrafluoroethylene insulation sleeve and the polytetrafluoroethylene partition can be used to wrap the connection end of the first connecting bracket 110 with the bolt assembly 130, so that the connection end of the first connecting bracket 110 with the bolt assembly 130 is completely not in direct contact with the bolt assembly 130, which can ensure the insulation between the first connecting bracket 110 and the bolt assembly 130, and further ensure the insulation between the radiator 200 and the body frame 300, and even in bad weather such as rainy days, it can achieve good insulation performance.

[0035] Example 2

[0036] This embodiment is similar to embodiment 1, except that Figures 1 to 3 As shown, in this embodiment, the bolt assembly 130 includes a flange bolt 131, a sleeve 132, and a nut 133. The sleeve 132 is sleeved with the flange bolt 131, the insulating member 140 is sleeved with the sleeve 132, and the first vibration damper 150 is located between the insulating member 140 and the flange head of the flange bolt 131; the second connecting bracket 120 is connected to the flange bolt 131 through the nut 133, and the second vibration damper 160 is located between the insulating member 140 and the second connecting bracket 120. In this embodiment, the nut 133 can be a flange nut.

[0037] During installation, firstly, the shaft sleeve 132 is installed on the flange bolt 131 to form a flange bolt group, and the insulating sleeve 141 is installed on the bolt connection end of the first connecting bracket 110; then, the first vibration damper 150, the first connecting bracket 110 with the insulating sleeve 141, the partition 142, the second vibration damper 160, and the second connecting bracket 120 are installed on the flange bolt group in sequence, and finally, the nut 133 is tightened to complete the installation. Figure 1 shown.

[0038] Example 3

[0039] This embodiment is similar to Embodiment 2, except that Figures 1 to 4 As shown, the first vibration damper 150 and the second vibration damper 160 are both provided with through holes for installation with the bolt assembly 130. In this embodiment, the shaft sleeve 132 is provided with a protruding portion 1321 protruding outward, and the through holes near one end of the protruding portion 1321 on the first vibration damper 150 and the second vibration damper 160 are both provided with a chamfered structure 170 for matching with the protruding portion 1321. The setting of the protruding portion 1321 can be used to adapt to the connection end of the first connecting bracket 110 with the bolt assembly 130, and the setting of the chamfered structure 170 can improve the connection tightness between the first vibration damper 150 and the bolt assembly 130, and between the second vibration damper 160 and the bolt assembly 130.

[0040] like Figure 1 and Figure 3 As shown, a first retaining ring 151 is provided at a through hole of the first vibration damper 150 away from one end of the shaft sleeve 132, and a second retaining ring is provided at a through hole of the second vibration damper 160 away from one end of the shaft sleeve 132. The provision of the first retaining ring 151 can reduce the wear between the flange head of the flange bolt 131 and the shaft sleeve 132, and the provision of the second retaining ring can reduce the wear between the second connecting bracket 120 and the shaft sleeve 132, thereby improving the service life of the radiator insulation device.

[0041] like Figure 1 and Figure 3 As shown, when the first vibration damper 150 is not extruded and deformed, there is a gap 180 between the bolt assembly 130 and the first vibration damper 150 in the extrusion direction; similarly, when the second vibration damper 160 is not extruded and deformed, there is a gap 180 between the bolt assembly 130 and the second vibration damper 160 in the extrusion direction. The setting of the gap 180 can provide a position space for the first vibration damper 150 and the second vibration damper 16 to install and deform. Specifically, there is a gap 180 in the vertical direction between the through hole of the first vibration damper 150 and the shaft sleeve 132, and there is a gap 180 in the vertical direction between the through hole of the second vibration damper 160 and the shaft sleeve 132. In this embodiment, the first vibration damper 150 and the second vibration damper 160 are both vibration damping rubber pads, and specifically, the vibration damping rubber pads can be rubber pads.
