[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0056] Hereinafter, reference will be made to Figures 1 to 4 Describe in detail the suspension device, hydrogen fuel cell environmental chamber and vehicle of the hydrogen fuel cell environmental chamber according to the embodiments of the present invention.

[0057] Figure 1 is a three-dimensional exploded view of the hydrogen fuel cell environmental chamber according to the embodiment of the present invention. As Figure 1 shown, the hydrogen fuel cell environmental chamber 100 according to the embodiment of the present invention may include: an upper housing 110; a lower housing 120, which is combined with the upper housing 110 to form an accommodation space; a hydrogen fuel cell system 130, which is disposed in the accommodation space; and a suspension device 150, and the suspension device 150 suspends and mounts the hydrogen fuel cell system 130 on the lower housing 120.

[0058] According to the embodiment of the present invention, the hydrogen fuel cell system 130 may include a hydrogen stack, an air system and a hydrogen system. In addition, the hydrogen fuel cell system 130 may further include a thermal management system, a fuel cell control unit (FCU), internal wiring harness and a DC / DC converter.

[0059] According to the embodiment of the present invention, the hydrogen fuel cell system 130 may be disposed in the accommodation space surrounded by the upper housing 110 and the lower housing 120, and the hydrogen fuel cell system 130 may be suspended and mounted on the lower housing 120 by using the suspension device 150. The suspension device 150 (the structure thereof will be described later) may have the functions of shock absorption and buffering, so it can avoid great damage to the hydrogen fuel cell system 130 caused by the violent vibration of the vehicle (for example, when encountering an uneven road surface during driving), which is beneficial to avoiding power generation power fluctuations and / or affecting its service life.

[0060] As Figure 1As shown, the hydrogen fuel cell environmental chamber 100 may include four suspension devices 150 disposed around the hydrogen fuel cell system 130. For stable support, a pair of suspension devices 150 are provided on each of the opposite sides of the hydrogen fuel cell system 130. However, the present utility model is not limited thereto, and the hydrogen fuel cell environmental chamber may include at least four suspension devices 150 disposed around the hydrogen fuel cell system 130, that is, five, six or more suspension devices 150 may be provided.

[0061] The top of the suspension device 150 may be fixed to the support block 132 extending outward from the hydrogen fuel cell system 130, and the bottom of the suspension device 150 may be fixed to the mounting block 121 extending inward from the side wall of the lower housing 120. When the direction in which the upper housing 110 and the lower housing 120 face each other is the thickness direction, the support block 132 and the mounting block 121 may face each other in the thickness direction.

[0062] Hereinafter, reference will be made to Figures 2 to 4 describe the suspension device 150 according to an embodiment of the present utility model.

[0063] Figure 2 is a suspension device according to the first embodiment of the present utility model. As Figure 2 shown, the suspension device 150 according to an embodiment of the present utility model may include: a base 151 for mounting to the lower housing 120; a cylinder 152 fixed to the base 151, and a magnetic fluid 152a is filled in the cylinder 152; a piston 153 disposed in the cylinder 152 and capable of moving along the axial direction of the cylinder 152, the piston 153 divides the cylinder 152 into a first space and a second space, and the magnetic fluid 152a in the first space communicates with the magnetic fluid 152a in the second space; a coil 154 wound around the piston 153; a piston rod 155, one end of the piston rod 155 is connected to the piston 153, and the other end of the piston rod 155 extends out of the cylinder 152; a top plate 156 connected to the other end of the piston rod 155, and the top plate 156 is used for mounting to the hydrogen fuel cell system 130; a spring 157 disposed between the top plate 156 and the base and sleeved outside the cylinder 152.

[0064] As Figure 2 shown, the suspension device 150 may include a base 151, in combination with Figure 1 shown, the base 151 may be fixed to the mounting block 121. The base 151 may be fixed to the mounting block 121 by means of bolt connection or the like, and the present utility model does not make specific limitations thereto. The base 151 may be in a circular shape, however, the present utility model is not limited thereto, and the base 151 may also have other shapes such as a rectangle.

[0065] As Figure 2As shown, the suspension device 150 may further include a cylinder 152, a piston 153 disposed in the cylinder 152, a coil 154 disposed in the piston 153, and a piston rod 155 connected to the piston 153.

[0066] The cylinder 152 may be fixed to the base 151. For example, the bottom of the cylinder 152 may be fixed to the base 151. The cylinder 152 is filled with a ferrofluid 152a. The ferrofluid 152a, also known as magnetic liquid, ferromagnetic fluid or magnetic fluid, is a new type of functional material that has both the fluidity of a liquid and the magnetism of a solid magnetic material.

[0067] The piston 153 may be disposed in the cylinder 152 and be capable of moving axially along the cylinder 152 under the drive of the piston rod 155. The piston 153 may divide the cylinder 152 into a first space and a second space. The ferrofluid 152a in the first space is in communication with the ferrofluid 152a in the second space. Therefore, a damping channel may be formed between the upper and lower chambers of the piston 153, and the ferrofluid 152a flows between the upper and lower chambers of the piston through the damping channel, thereby generating a damping force. For example, an annular hole 153a may be formed in the piston 153 to communicate the ferrofluid 152a in the first space with the ferrofluid 152a in the second space to form a damping channel. Alternatively, at least a part of the outer periphery of the piston 153 may be separated from the inner wall of the cylinder 152 to communicate the first space and the second space to form a damping channel.

[0068] The coil 154 may be wound around the piston 153, and the coil 154 can obtain an electric current. For example, the coil 154 may be electrically connected to a power supply device through an electric wire disposed on the piston rod 155. However, the manner of supplying power to the coil 154 is not limited thereto.

[0069] One end of the piston rod 155 is connected to the piston 153, and the other end of the piston rod 155 extends out of the cylinder 152 and is connected to the top plate 156. The top plate 156 is used for installation to the hydrogen fuel cell system 130. Specifically, as Figure 1 shown, the top plate 156 is fixed to (for example, bolted to) a support block 132 extending outward from the hydrogen fuel cell system 130. The top plate 156 may be circular in shape. However, the present invention is not limited thereto, and the top plate 156 may also have other shapes such as a rectangle.

[0070] As Figure 2 shown, the suspension device 150 may further include a spring 157. The spring 157 may be disposed between the top plate 156 and the base 151 and sleeved outside the cylinder 152. When the top plate 156 moves downward due to vibration, the spring 157 may play a role in shock absorption.

[0071] According to an embodiment of the present invention, in order to define the deformation path of the spring 157, as Figure 2As shown, the suspension device 150 may further include a first sleeve 158. The first sleeve 158 may be sleeved outside the spring 157 so that the spring 157 deforms between the first sleeve 158 and the cylinder 152. One end of the first sleeve 158 may be fixed to the base 151, and the other end of the first sleeve 158 may be separated from the top plate 156 to avoid interfering with the downward movement of the top plate 156.

[0072] According to the present utility model, when an electric current passes through the coil 154, under the action of the magnetic field, the viscosity and yield strength of the magnetorheological fluid 152a at the damping channel change, thereby increasing the damping force. When the vehicle jolts, the hydrogen fuel cell system 130 applies a certain downward force to the top plate 156. When this force is greater than the elastic force of the spring 157, the top plate 156 pushes the piston rod 155 downward and drives the piston 153 to perform damping movement in the cylinder 152. Therefore, buffering of the vibration of the hydrogen fuel cell system can be achieved, and damage to the hydrogen fuel cell system caused by vibration can be reduced.

[0073] In addition, according to the present utility model, by adjusting the magnitude of the electric current in the coil 154, the magnetic field strength at the damping channel can be changed to change the magnitude of the damping force, so that the magnitude of the electric current can be controlled according to the jolting condition of the vehicle to change the magnitude of the damping force. Therefore, the suspension device 150 according to the present utility model can dynamically adjust the vibration suppression ability, improve the buffering ability, and avoid damage caused by resonance between the hydrogen fuel cell system 130 and the vehicle.

[0074] Figure 3 is a suspension device according to the second embodiment of the present utility model. As Figure 3 shown, the suspension device 150 may further include a second sleeve 159. The second sleeve 159 is sleeved outside the first sleeve 158 and can move axially along the first sleeve 158. One end of the second sleeve 159 is fixed to the top plate 156. For example, the second sleeve 159 and the top plate 156 may be integrally formed, or the second sleeve 159 and the top plate 156 are separately formed and the second sleeve 159 is fixed to the top plate 156 by means such as threaded connection or welding. The other end of the second sleeve 159 is separated from the base 151 to avoid interfering with the downward movement of the second sleeve 159.

[0075] The second sleeve 159 can move relative to the first sleeve 158 along with the top plate 156, thereby restricting the lateral relative movement between the first sleeve 158 and the second sleeve 159, and reducing the lateral vibration of the hydrogen fuel cell system.

[0076] In addition, as Figure 3As shown, rolling elements 159a may be provided between the second sleeve 159 and the first sleeve 158, such that rolling friction occurs between the first sleeve 158 and the second sleeve 159 through the rolling elements 159a, so as to reduce the wear caused by relative movement between the first sleeve 158 and the second sleeve 159.

[0077] Figure 4 is a suspension device according to the third embodiment of the present invention. Figure 4 The suspension device of Figure 3 The difference between the suspension device and the suspension device of

[0078] According to the present invention, by providing rolling elements 159a or nylon rings 159b between the first sleeve 158 and the second sleeve 159, the second sleeve 159 can move more smoothly relative to the first sleeve 158.

[0079] The following will return to refer to Figure 1 to describe other structures of the hydrogen fuel cell environmental chamber 100.

[0080] The hydrogen stack in the hydrogen fuel cell system 130 is the core component of the hydrogen fuel cell system 130. The air supplied by the air system and the hydrogen supplied by the hydrogen system undergo an electrochemical reaction in the hydrogen stack, directly converting the chemical energy of hydrogen and oxygen into electrical energy.

[0081] The hydrogen stack needs to operate at a suitable working temperature. At this working temperature, the reaction rate of hydrogen and oxygen is relatively fast, and at the same time, the stability of the electrolyte membrane can be ensured. If the temperature is too high, the electrolyte membrane may lose stability, thereby affecting the performance of the battery. If the temperature is too low, the reaction rate will slow down, and the output power of the battery will also decrease.

[0082] In the prior art, the hydrogen fuel cell system is exposed to the external environment. When the external environment temperature is too high, the power generation of the hydrogen fuel cell system will fluctuate, and the service life of the hydrogen fuel cell system will also be reduced.

[0083] According to an embodiment of the present invention, the hydrogen fuel cell environmental chamber 100 may further include an air conditioner 140. By placing the hydrogen fuel cell system 130 in the accommodation space formed by the upper housing 110 and the lower housing 120, and providing an air conditioner 140 in this accommodation space, the temperature in the accommodation space can be adjusted, thereby adjusting the operating temperature of the hydrogen stack, which is beneficial for it to operate at the working temperature, so as to stabilize the power generation and improve its service life. In addition, by placing the hydrogen fuel cell system 130 in the accommodation space, it is also possible to prevent moisture and dust in the external air from directly contacting the hydrogen fuel cell system 130, which is beneficial for improving the power generation and service life of the hydrogen fuel cell system 130.

[0084] According to an embodiment of the utility model, the air conditioner 140 may have a cooling mode. When the outside temperature is too high and / or the heat generated by the operation of the hydrogen fuel cell system 130 itself causes the temperature in the accommodation space to exceed the working temperature, the air conditioner 140 may be turned on for cooling to reduce the temperature in the accommodation space to the working temperature.

[0085] Since the hydrogen fuel cell system 130 generates heat when it is running, when the ambient temperature is low, the hydrogen fuel cell system 130 can reach the operating temperature after running for a period of time. Therefore, the air conditioner 140 may not have a heating mode. Optionally, the air conditioner 140 may also have a heating mode, so that the temperature in the accommodation space can be quickly increased by heating the air conditioner 140 so that the hydrogen stack can reach the operating temperature more quickly.

[0086] According to an embodiment of the present invention, the air conditioner 140 may be an integrated air conditioner capable of achieving refrigeration or capable of achieving refrigeration and heating. For example, the air conditioner 140 may integrate a condenser, an evaporator, a compressor, an expansion valve, a pipeline, and all other system components into an integral chassis. The present invention does not limit the specific structure of the air conditioner 140, but may apply any integrated air conditioner capable of achieving refrigeration and heating known in the art.

[0087] According to an embodiment of the present invention, the air conditioner 140 may be installed on the lower housing 120. The air inlet of the air conditioner 140 may pass through the upper housing 110 to communicate with the outside, and the air outlet of the air conditioner 140 communicates with the accommodation space to supply cold air or hot air to the accommodation space as needed.

[0088] In addition, according to the embodiment of the utility model, the air conditioner 140 and the hydrogen fuel cell system 130 can be installed on the lower shell 120, so that the strength can be ensured by increasing the rigidity of the lower shell 120. The upper shell 110 does not play a load-bearing role, but mainly serves as a cover, which is beneficial to the lightweight of the upper shell 110, thereby facilitating the weight reduction of the entire hydrogen fuel cell environmental chamber 100.

[0089] According to the embodiments of the present utility model, Figure 1 As shown, the air system of the hydrogen fuel cell system 130 may include an air filter 131. Figure 1 As shown, the top wall of the upper shell 110 may be provided with an upper shell opening 111, and the upper shell 110 may also include an air intake grille 112 covering the upper shell opening 111, and the air intake grille 112 is connected to the air filter 131, and the external air is initially filtered through the air intake grille 112 and then enters the air filter 131 for re-filtration.

[0090] According to the embodiments of the present utility model, Figure 1As shown, the air system may further include an exhaust port 163 for discharging the tail gas after the reaction. The exhaust port 163 passes through the lower housing 120 and is spaced apart from the lower housing 120. An elastic sealing cover may be used to seal between the exhaust port 163 and the lower housing 120 to prevent moisture and dust from entering the accommodation space.

[0091] According to an embodiment of the present invention, as Figure 1 shown, the hydrogen fuel cell system 130 may further include a coolant interface 161 for communicating with the thermal management system of the hydrogen fuel cell system 130. Figure 1 Two coolant interfaces 161 are shown in Figure 1 which respectively pass through the upper housing 110 and the lower housing 120 and are spaced apart from the upper housing 110 and the lower housing 120. As

[0092] Figure 1 shown, elastic sealing covers may be used to seal between the coolant interfaces 161 and the upper housing 110 and the lower housing 120 to prevent moisture and dust from entering the accommodation space.

[0093] According to an embodiment of the present invention, as Figure 1 shown, a wire harness outlet 162 may be further provided on the upper housing 110 and / or the lower housing 120.

[0094] According to an embodiment of the present invention, a vehicle including the above hydrogen fuel cell environment chamber 100 may be further provided. As an example, the hydrogen fuel cell environment chamber 100 may be installed on the chassis of the vehicle, however, the present invention does not make specific limitations thereto. In addition, the present invention does not make specific limitations on the type of the vehicle. For example, the vehicle may be a logistics vehicle, a sedan, a small commuting vehicle, etc.

[0095] According to an embodiment of the present invention, the vehicle may further include a power source for supplying current to the coil 154 and a current controller for adjusting the magnitude of the current of the power source.

[0096] In addition, according to an embodiment of the present invention, the vehicle may further include a vehicle vibration sensor, which can sense the vehicle vibration signal and transmit the vehicle vibration signal to the current controller. The vehicle vibration sensor can send a signal to the current controller according to the magnitude of the vehicle bump, so that the current controller adjusts the magnitude of the current acting on the coil 154. Therefore, according to the present invention, by adjusting the magnitude of the current in the coil 154, the magnetic field strength can be changed to change the damping force magnitude, so that the magnitude of the current can be controlled according to the bump situation of the vehicle, and the vibration suppression ability of the suspension device 150 can be dynamically adjusted to avoid resonance and damage between the hydrogen fuel cell system 130 and the vehicle.

[0097] According to the suspension device and the hydrogen fuel cell environmental chamber of the present invention described above, beneficial technical effects not limited to the following description can be achieved.

[0098] According to the present invention, shock absorption and vibration buffering of the hydrogen fuel cell system can be realized, and damage to the hydrogen fuel cell system caused by vibration can be reduced.

[0099] According to the present invention, the vibration suppression ability of the suspension device can be dynamically adjusted according to the bump situation of the vehicle, the buffering ability can be improved, and resonance and damage between the hydrogen fuel cell system and the vehicle can be avoided.
