The integrated valve assembly is disposed on the housing, its outlet is connected to a hydrogen-using device, and its inlet is connected to a cylinder valve of a hydrogen storage device through the quick-connect coupling. The locking and releasing device is disposed outside the housing and is used to lock or unlock the connection between the integrated valve assembly and the hydrogen storage device. The system is characterized by further including a blocking rod disposed on the push rod of the locking and releasing device, the axis of the blocking rod being perpendicular to the axis of the push rod. A locking device is disposed outside the housing and is communicatively connected to a control mainboard. The control mainboard controls the locking device to cooperate with the blocking rod to lock or unlock the axial movement limit of the push rod.

[0008] In one embodiment, the locking device includes a driver and a limiting plate. The limiting plate is disposed on the side of the blocking rod away from the open end face of the housing and close to the blocking rod. The driver is connected to the limiting plate and is used to drive the limiting plate to move, so as to block or allow the blocking rod to move in the direction away from the open end face of the housing.

[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 a 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, this embodiment provides a hydrogen supply system for housing a hydrogen storage device 200 and for sealingly connecting to the bottle valve of the hydrogen storage device 200. The hydrogen supply system includes a housing 110, an integrated valve assembly 120, a quick-connect coupling, a locking and releasing device 140, and a locking device 150. The housing 110 houses the hydrogen storage device 200. The integrated valve assembly 120 is mounted on the housing 110, with its outlet 121 connected to a hydrogen-using device and its inlet connected to the bottle valve of the hydrogen storage device 200 via the quick-connect coupling. The locking and releasing device 140 is located outside the housing 110 and is used to lock or unlock the connection between the integrated valve assembly 120 and the hydrogen storage device 200. The locking device 150 is communicatively connected to a control motherboard and is used to restrict the function of the locking and releasing device 140 according to authorized conditions.

[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 releasing 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 at the end 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] Please combine Figure 3 To restrict the 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 in this embodiment 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, and 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 actuator 151 can be a motor, connected to the limiting plate 152 via a rotating disk 154. To control the overall size of the hydrogen supply system, the axis of the output shaft of the actuator 151 can be parallel to the axis of the push rod 141, ensuring that the overall projection of the actuator 151 does not exceed the projection of the housing 110. Please refer to... Figure 4 The center of the rotating disk 154 is fixedly connected to the output shaft of the driver 151. A 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. 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 protrusion 1541 is installed in the second through hole 1522. When the driver 151 is started, it drives the rotating disk 154 and the protrusion 1541 on it to rotate. Under the constraint of the second through hole 1522, the rotation of the protrusion 1541 will drive the limiting plate 152 to move on the slide rail 153.

[0038] Specifically, the driver 151 can be controlled to start and stop via a control program. After each start-up, the driver 151 drives the rotating disk 154 to rotate 180° and then stops immediately. Assuming the initial state is that the protrusion 1541 is located closest to the push rod 141 (i.e., locked state), 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, thus preventing the hydrogen storage device 200 from being removed from the housing 110.

[0039] In the locked state, when the user authorizes an unlocking operation, the control program activates the driver 151 to drive the rotating disk 154 to rotate 180°, so that the protrusion 1541 rotates to the position furthest away from the push rod 141 (i.e., the unlocked state). At this time, 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 the quick-connect male connector 132, disconnecting the hydrogen storage device 200 from the integrated valve assembly 120, thereby allowing the hydrogen storage device 200 to be removed from the housing 110.

[0040] In the unlocked state, when the user authorizes the locking operation, the control program starts the driver 151 to drive the rotating disk 154 to rotate 180° and return to the locked state, that is, the protrusion 1541 is back in the position closest to the push rod 141.

[0041] Please review Figure 1 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 sliding 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.

[0042] In summary, the hydrogen supply system provided in this embodiment adds a blocking rod 145 to the push rod 141 and a locking device 150 to the housing 110. The blocking rod 145 can cooperate with the locking device 150 to limit the axial movement of the push rod 141, ensuring that the locking and releasing device 140 can only be activated to unlock the quick connector with the authorization of the user / maintenance personnel, thereby removing the hydrogen storage device 200. This realizes intelligent control of the removal and placement of the hydrogen storage device 200 and improves the reliability of the anti-theft design of the hydrogen supply system.

[0043] Example 2:

[0044] This embodiment provides a hydrogen-powered vehicle, including a frame, a hydrogen supply system as described in Embodiment 1, and a control mainboard. Both the hydrogen supply system and the control mainboard are mounted on the frame, and the control mainboard controls the operation of the driver 151.

[0045] When the user is not authorized or the device is not locked for a long time, the control motherboard controls the driver 151 to be powered on and rotate normally, which indirectly drives the limiting piece 152 to move the push rod 141 to the side of the first through hole 1521 near 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 taking out the hydrogen storage device 200 at will.

[0046] When the user or maintenance personnel authorize the removal of the hydrogen storage device 200 from the housing 110, the control motherboard controls the driver 151 to rotate normally, indirectly driving the limiting plate 152 to move the push rod 141 to the side of the first through hole 1521 away from the blocking rod 145. That is, the blocking rod 145 is not interfered with by the limiting plate 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.

[0047] In summary, the hydrogen supply system for the hydrogen-powered vehicle provided in this embodiment adds a blocking rod 145 to the push rod 141 and a locking device 150 to the housing 110. The blocking rod 145 can cooperate with the locking device 150 to limit the axial movement of the push rod 141, ensuring that the locking and releasing device 140 can only be activated to unlock the quick connector with the authorization of the user / maintenance personnel, thereby removing the hydrogen storage device 200. This realizes intelligent control of the removal and placement of the hydrogen storage device 200 and improves the reliability of the anti-theft design of the hydrogen supply system.

[0048] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
