Technical Field

[0001] This invention relates to the field of hydrogen energy storage technology, specifically to an intelligent gas storage tank and a hydrogen-powered vehicle equipped with it. Background Technology

[0002] In the field of hydrogen fuel cell bicycles, whether for shared mobility or personal use, the secure installation and anti-theft measures of hydrogen storage cylinders are crucial to the normal operation of hydrogen fuel cell bicycles. However, the current installation methods for hydrogen storage cylinders in hydrogen fuel cell bicycles cannot effectively prevent unauthorized personnel from taking the hydrogen storage cylinders from the gas storage compartment. When using existing anti-theft structures from other fields for the gas storage compartment, they cannot be well adapted to the quick-connect gas circuit device in the gas storage compartment. For example, the quick-connect gas circuit device in the prior application with publication number CN118482254A is difficult to accurately and automatically lock or unlock, and is prone to problems such as missed locks or insecure locking. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an intelligent gas storage tank and a hydrogen-powered vehicle with it, which can solve the problems of the lack of anti-theft function in the existing gas storage tank and the easy occurrence of missing locks or weak locking in the anti-theft structure.

[0004] To achieve the above and other objectives, the present invention is implemented through the following technical solution: As a first aspect, the present invention proposes an intelligent gas storage chamber, comprising a shell, an integrated valve assembly, a quick-connect connector, and a locking and unlocking device. The integrated valve assembly is disposed on the shell, its outlet connected to a hydrogen storage device, and its inlet connected to a cylinder valve of the hydrogen storage device via the quick-connect connector. The locking and unlocking device is disposed outside the shell and is used to lock or unlock the connection between the integrated valve assembly and the hydrogen storage device. The invention is characterized by further comprising a locking device disposed outside the shell and communicatively connected to a control motherboard; and a detection device communicatively connected to both the locking device and the control motherboard. The control motherboard controls the locking device to lock or unlock the locking and unlocking device according to remote authorization and operational requirements, and simultaneously controls the detection device to detect the position of the locking device. When the locking device reaches a designated position, the detection device outputs a power-off command to the locking device.

[0005] In one embodiment, the push rod of the locking and releasing device is provided with a blocking rod, the axis of which is perpendicular to the axis of the push rod; the limiting piece of the locking device is disposed on the side of the blocking rod away from the open end face of the housing and is close to the blocking rod; the driver of the locking device drives the limiting piece to move to block or allow the blocking rod to move away from the open end face of the housing; the detection device is used to detect the position of the limiting piece.

[0006] In one embodiment, the detection device includes a first grating module and a second grating module, and the second protrusion of the limiting piece moves between the grating position of the first grating module and the grating position of the second grating module; when the second protrusion is located at the grating position of the first / second grating module, the first / second grating module sends a power-off command to the driver.

[0007] In one embodiment, the limiting piece is sleeved on the push rod through a first through hole thereon, the length direction of the first through hole is parallel to the axial direction of the blocking rod, and the length of the first through hole is greater than or equal to the sum of the diameter of the push rod and the axial length of the blocking rod; the driver drives the limiting piece to move along the length direction of the first through hole.

[0008] In one embodiment, the limiting piece is limited to slide between the slide rail and the cover plate; the cover plate is provided with a limiting through hole, the length direction of the limiting through hole is consistent with the length direction of the first through hole; the second protrusion protrudes from the upper end surface of the cover plate and slides in the limiting through hole.

[0009] In one embodiment, the first grating module and the second grating module are respectively disposed at both ends of the length direction of the limiting through hole; the first end and the second end of the first / second grating module are respectively spanning both sides of the width direction of the limiting through hole.

[0010] In one embodiment, the limiting through hole is formed on the side of the cover plate near the driver.

[0011] In one embodiment, the axial direction of the output shaft of the driver is parallel to the axial direction of the push rod; the driver is connected to the limiting plate through a rotating disk, and the driver drives the rotating disk to rotate, causing the limiting plate to move along the length direction of the first through hole.

[0012] In one embodiment, a first protrusion is provided on the end face of the rotating disk away from the driver, and the first protrusion is installed in the second through hole of the limiting plate; the length direction of the second through hole is perpendicular to both the axial direction of the output shaft of the driver and the length direction of the first through hole.

[0013] As a second aspect, the present invention provides a hydrogen-powered vehicle, including a smart gas storage tank as described in the first aspect.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The locking device of the present invention achieves intelligent motion control through the control motherboard, ensuring that only authorized users or maintenance personnel can access the hydrogen storage device, thereby effectively preventing unauthorized access. This not only protects the user's property safety but also avoids potential safety hazards caused by misoperation or illegal access. At the same time, the detection device can perform precise position control of the locking device to avoid problems such as missed locking or insecure locking, thus improving overall safety and reliability.

[0016] 2. The present invention adds a blocking rod to the push rod. The blocking rod can cooperate with the locking device to limit the axial movement of the push rod. The driver and limiting plate design of the locking device are simple in structure, low in cost, and have a high locking / unlocking success rate.

[0017] 3. This invention uses a grating module to identify the transmission of light signals, thereby achieving precise control over the locking / unlocking state of the limiting plate. Compared to the method of relying solely on the limiting plate to collide with the push rod to sense whether the movement is in place, this invention avoids the problems of missed locking or insecure locking, and also prevents the limiting plate from excessively pressing against and squeezing the push rod, thus damaging the push rod.

[0018] 4. The design of the first through hole on the limiting plate of the present invention can improve the effectiveness of the cooperation between the limiting plate and the blocking rod, and further improve the success rate of locking / unlocking.

[0019] 5. The design of the slide rail and cover plate of this invention can provide the sliding direction of the limiting piece, thereby improving the sliding stability of the limiting piece;

[0020] 6. The limiting through hole of the present invention is located closer to the force actuator, which can reduce the communication distance between the grating module and the actuator;

[0021] 7. The setting direction of the driver of the present invention can ensure that the overall projection of the driver does not exceed the projection of the housing, making the overall size of the locking device small and exquisite, and suitable for installation in narrow spaces inside a vehicle.

[0030] In this invention, the serial numbers assigned to components, such as "first," "second," etc., are merely used to distinguish the described objects and have no sequential or technical meaning. The term "connection" in this invention, unless otherwise specified, includes both direct and indirect connections. The terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, encompassing not only the listed elements but also other elements not expressly listed.

[0031] Example 1:

[0032] like Figure 1 and Figure 2As shown, the present invention provides an intelligent gas storage chamber for accommodating a hydrogen storage device 200 and sealingly connecting it to the bottle valve of the hydrogen storage device 200. The intelligent gas storage chamber includes a housing 110, an integrated valve assembly 120, a quick-connect coupling, a locking and releasing device 140, a locking device 150, and a detection device 160. The housing 110 accommodates the hydrogen storage device 200. The integrated valve assembly 120 is disposed on the housing 110, with an outlet 121 connected to a hydrogen-using device and an inlet connected to the bottle valve of the hydrogen storage device 200 via the quick-connect coupling. The locking and releasing device 140 is disposed outside the housing 110 and is used to lock or unlock the integrated valve assembly. 120 is connected to the hydrogen storage device 200; the locking device 150, the detection device 160, and the control board of the hydrogen vehicle are connected in pairs for communication. The control board controls the locking device 150 to lock or unlock the locking and unlocking device 140 according to the remote authorization and operation requirements. At the same time, it controls the detection device 160 to detect the position of the locking device 150 and can immediately send a power-off command to the locking device 150 after the locking device 150 is in place, so as to achieve precise locking or unlocking control.

[0033] Specifically, the quick-connector includes a quick-connect female connector 131 that is sealed to the integrated valve assembly 120 and a quick-connect male connector 132 that is sealed to the hydrogen storage device 200; the quick-connect female connector 131 is provided with an opening and closing sliding sleeve 133 that cooperates with the quick-connect male connector 132. The locking and unlocking device 140 is disposed outside the housing 110 and includes a push rod 141, a slider 142, an elastic element 143, and a button 144. The push rod 141 is disposed parallel to the central axis of the hydrogen storage device 200 and is disposed outside the housing 110 by multiple mounting parts. Its two ends are respectively slidably disposed on the closed end face and the open end face of the housing 110. One end of the slider 142 is fixed to the push rod 141, and the other end is engaged on the outer edge of the opening and closing sliding sleeve 133. The elastic element 143 is sleeved on the push rod 141 and is located between the slider 142 and the closed end face of the housing 110 to keep the slider 142 detached from the opening and closing sliding sleeve 142. The button 144 is disposed on the side of the push rod 141 near the open end face of the housing 110.

[0034] When authorized to replace the hydrogen storage device 200, firstly, by pressing the button 144, the push rod 141 drives the slider 142 to push the opening and closing sleeve 133 to move away from the quick-connect male connector 132, causing the quick-connect female connector 131 to automatically pop out of the quick-connect male connector 132, unlocking the connection between the hydrogen storage device 200 and the integrated valve assembly 120, and automatically popping out the bottom 201 of the hydrogen storage device 200 for easy removal; then, the hydrogen storage device 200 filled with hydrogen is inserted into the housing 110 and gently pushed towards the integrated valve assembly 120, installing the quick-connect male connector 132 of the hydrogen storage device 200 onto the quick-connect female connector 131 of the integrated valve assembly 120, realizing automatic docking and completing the hydrogen replacement operation. When the hydrogen replacement operation is not authorized, the locking device 150 restricts the movement of the push rod 141. Pressing the button 144 will not push the push rod 141 to move, and the quick connector cannot be unlocked, thus preventing the hydrogen storage device 200 from being removed. This avoids the problem that non-users or non-maintenance personnel can arbitrarily remove the hydrogen storage device 200.

[0035] like Figure 3 and Figure 4 As shown, in order to restrict the axial movement of the push rod 141 by the locking device 150, unlike the push rod 141 in the prior application with publication number CN118482254A, the push rod 141 of this invention is provided with a blocking rod 145 perpendicular to the axial direction of the push rod 141. The blocking rod 145 can cooperate with the locking device 150 to limit the axial movement of the push rod 141, ensuring that the hydrogen storage device 200 can only be removed by pressing the button 144 with the authorization of the user or maintenance personnel. Otherwise, the button 144 is locked and cannot be pressed to remove the hydrogen storage device 200. No one may remove the hydrogen storage device 200 without permission.

[0036] Specifically, the locking device 150 is fixed to the outside of the housing 110 and includes a driver 151 and a limiting piece 152. The limiting piece 152 is slidably mounted on the outside of the housing 110 via a slide rail 153 fixed to the housing 110. The slide rail 153 is parallel to the axial direction of the blocking rod 145. The limiting piece 152 has a first through hole 1521, which is an oblong hole. The limiting piece 152 is sleeved on the push rod 141 through the first through hole 1521, and the limiting piece 152 is located close to the blocking rod 145 on the side of the blocking rod 145 away from the button 144. The length direction of the first through hole 1521 is parallel to the axial direction of the blocking rod 145, and the length of the first through hole 1521 is greater than or equal to the sum of the diameter of the push rod 141 and the axial length of the blocking rod 145. The driver 151 is connected to the limiting piece 152 and is used to drive the limiting piece 152 to move along the length direction of the first through hole 1521. When the end of the first through hole 1521 near the blocking rod 145 abuts against the push rod 141, the limiting piece 152 restricts the movement of the blocking rod 145 away from the button 144, which means that the button 144 is locked and cannot be pressed. When the end of the first through hole 1521 away from the blocking rod 145 abuts against the push rod 141, the blocking rod 145 can pass through the first through hole 1521. Therefore, by pressing the button 144, the push rod 141 can be moved and the quick connector can be successfully unlocked.

[0037] Specifically, the driver 151 can be a motor, connected to the limiting plate 152 via a rotating disk 154. To control the overall size of the intelligent gas storage chamber, the axial direction of the output shaft of the driver 151 can be parallel to the axial direction of the push rod 141, ensuring that the overall projection of the driver 151 does not exceed the projection of the housing 110. The center of the rotating disk 154 is fixedly connected to the output shaft of the driver 151, and a first protrusion 1541 is provided on the end face of the rotating disk 154 away from the driver 151. A second through hole 1522 is provided at the end of the limiting plate 152 connected to the rotating disk 154, and the length direction of the second through hole 1522 is perpendicular to both the axial direction of the output shaft and the length direction of the first through hole 1521. The first protrusion 1541 is installed in the second through hole 1522. When the driver 151 is started, it drives the rotating disk 154 and the first protrusion 1541 on it to rotate. Under the restriction of the second through hole 1522, the rotation of the first protrusion 1541 will drive the limiting piece 152 to move on the slide rail 153.

[0038] When the first protrusion 1541 rotates to the position closest to the push rod 141, the push rod 141 is located on the side of the first through hole 1521 near the blocking rod 145. Therefore, the blocking rod 145 is interfered with by the limiting piece 152 and cannot move through the first through hole 1521. That is, when the button 144 is pressed, the button 144 is blocked and cannot be pressed. Therefore, the push rod 141 cannot move to disengage the quick-connect male connector 132 from the quick-connect female connector 131, and thus the hydrogen storage device 200 cannot be taken out from the housing 110.

[0039] When the first protrusion 1541 rotates to the position furthest from the push rod 141, the push rod 141 is located on the side of the first through hole 1521 away from the blocking rod 145. Therefore, the blocking rod 145 is not interfered with by the limiting piece 152 and can move through the first through hole 1521 together with the push rod 141. That is, when the button 144 is pressed, the button 144 can be pressed and drive the slider 142 on the push rod 141 to push the opening and closing sleeve 133 to move away from the quick-connect male connector 132, so that the quick-connect female connector 131 automatically pops out of the quick-connect male connector 132, disconnecting the hydrogen storage device 200 from the integrated valve assembly 120, so that the hydrogen storage device 200 can be taken out from the housing 110.

[0040] To ensure the sliding stability of the limiting piece 152, a cover plate 155 with a sliding groove can be added above the limiting piece 152. The limiting piece 152 is limited to slide between the sliding groove track 153 and the cover plate 155 by the sliding groove. The cover plate 155 is mounted on the housing 110 by a mounting post. The mounting post can be fixed to the housing 110 with screws or can be integrally formed with the housing 110.

[0041] Please combine Figure 1 and Figure 5The detection device 160 is used to detect the position of the limiting piece 152. Specifically, the detection device 160 can be a grating detection assembly, which can be mounted on the cover plate 155 to facilitate the installation of the cover plate 155. In order for the detection device 160 to detect the position of the limiting piece 152, the position information of the limiting piece 152 needs to be displayed on the cover plate 155. Therefore, a second protrusion 1523 can be formed on the limiting piece 152, and a limiting through hole 1551 can be opened on the cover plate 155. The length direction of the limiting through hole 1551 is consistent with the length direction of the first through hole 1521, so that the second protrusion 1523 can be exposed on the upper end surface of the cover plate 155 and slide in the limiting through hole 1551. When the limiting piece 152 moves, the second protrusion 1523 also moves in the same direction and distance in the limiting groove.

[0042] Furthermore, since the detection device 160 needs to communicate with the driver 151, in order to reduce the communication distance between the two, the limiting through hole 1551 can be opened on the side of the cover plate 155 near the driver 151, and the second protrusion 1523 can be set on the side of the limiting piece 152 near the driver 151.

[0043] The grating detection assembly may include a first grating module 161 and a second grating module 162. The first grating module 161 and the second grating module 162 are respectively disposed at both ends of the length direction of the limiting through hole 1551. The first grating module 161 is used to detect whether the second protrusion 1523 is located at the end of the limiting through hole 1551 closest to the push rod 141. The second grating module 162 is used to detect whether the second protrusion 1523 is located at the end of the limiting through hole 1551 furthest from the push rod 141. The second protrusion 1523 moves between the grating position of the first grating module 161 and the grating position of the second grating module 162. The first and second ends of the first / second grating module 162 are respectively positioned across the width of the limiting through hole 1551. The first end emits light towards the second end. If the emitted light can reach the second end, the first / second grating module 162 does not send a power-off command to the driver 151. If the emitted light is blocked by the second protrusion 1523 and cannot reach the second end, the first / second grating module 162 sends a power-off command to the driver 151. The driver 151 then cuts off power, causing the limiting piece 152 to stop moving instantly and remain in place, thereby achieving precise control of the limiting piece 152 to lock or unlock the axial position of the push rod 141. Compared to the method of relying solely on the collision of the limiting piece 152 with the push rod 141 to sense whether the movement is in place, this embodiment can avoid the problem of inaccurate control of the operation of the driver 151, which can easily lead to missed locks or insecure locking. At the same time, it can avoid the limiting piece 152 excessively pressing against the push rod 141 and damaging the push rod 141, thereby avoiding affecting the function of the locking and unlocking device 140.

[0044] In summary, the intelligent gas storage tank provided in this embodiment innovatively incorporates a locking device 150 and a detection device 160. The locking device 150 achieves intelligent motion control via a control motherboard and can cooperate with the blocking rod 145 to limit the axial movement of the push rod 141, ensuring that only authorized users or maintenance personnel can access the hydrogen storage device 200. This effectively prevents unauthorized access, protecting not only the user's property but also avoiding potential safety hazards caused by misoperation or illegal access. Simultaneously, the detection device 160 can precisely control the position of the locking device 150, preventing issues such as missed locking or insecure locking, thus improving overall safety and reliability.

[0045] Example 2:

[0046] This embodiment provides a hydrogen fuel cell vehicle, including a frame, an intelligent gas storage tank as described in Embodiment 1, and a control mainboard. Both the intelligent gas storage tank and the control mainboard are mounted on the frame, and the control mainboard controls the operation of the driver 151.

[0047] When the user is unauthorized or the device is left unlocked for an extended period, the control motherboard powers on the driver 151 to rotate normally, indirectly causing the second protrusion 1523 of the limiting plate 152 to move within the limiting through hole 1551. Simultaneously, the first end of the first grating module 161 emits light towards the second end. When the second protrusion 1523 moves to the end of the limiting through hole 1551 closest to the push rod 141, the light emitted from the first end of the first grating module 161 is blocked by the second protrusion 1523 and cannot reach or fully reach the second end. The first grating module 161 sends a power-off command to the driver 151. The driver 151 de-energizes the second protrusion 1523, causing it to stop at the end of the limiting through hole 1551 closest to the push rod 141. At this time, the push rod 141 is located on the side of the first through hole 1521 closest to the blocking rod 145. That is, the blocking rod 145 is interfered with by the limiting piece 152 and cannot move through the first through hole 1521. At this time, the hydrogen storage device 200 cannot be removed by pressing the button 144, which can prevent others from removing the hydrogen storage device 200 at will.

[0048] When the user remotely authorizes or the maintenance personnel authorize the removal of the hydrogen storage device 200 from the housing 110, the control motherboard controls the driver 151 to be powered on and rotate normally, indirectly driving the second protrusion 1523 of the limiting plate 152 to move within the limiting through hole 1551. Simultaneously, the first end of the second grating module 162 emits light from the second end. When the second protrusion 1523 moves to the end of the limiting through hole 1551 furthest from the push rod 141, the light emitted from the first end of the second grating module 162 cannot reach the second end due to the obstruction of the second protrusion 1523. If the second end cannot be fully reached, the second grating module 162 sends a power-off command to the driver 151. The driver 151 de-energizes the second protrusion 1523, causing it to stop at the end of the limiting through hole 1551 furthest from the push rod 141. At this time, the push rod 141 is located on the side of the first through hole 1521 away from the blocking rod 145, meaning that the blocking rod 145 is not interfered with by the limiting piece 152 and can move through the first through hole 1521 together with the push rod 141. At this time, the user or maintenance personnel can remove the hydrogen storage device 200 by pressing the button 144.

[0049] In summary, the hydrogen-powered vehicle provided in this embodiment innovatively features an intelligent gas storage compartment equipped with a locking device 150 and a detection device 160. The locking device 150 achieves intelligent motion control via a control motherboard and can cooperate with the blocking rod 145 to limit the axial movement of the push rod 141, ensuring that only authorized users or maintenance personnel can access the hydrogen storage device 200. This effectively prevents unauthorized access, protecting not only the user's property but also avoiding potential safety hazards caused by misoperation or illegal access. Simultaneously, the detection device 160 can precisely control the position of the locking device 150, preventing issues such as missed locking or insecure locking, thus improving overall safety and reliability.

[0050] Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial applicability. The above embodiments are merely illustrative of the principles and effects of this invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this invention.
