Description

Technical Field

[0001] The invention belongs to the technical field of new energy, and in particular relates to a solid-state hydrogen storage tank valve for electric bicycles which is convenient for activation and hydrogen charging. Background Art

[0002] With the successful application of small solid-state hydrogen storage tanks in electric bicycles (with small battery stacks), a 2L solid-state hydrogen storage tank can drive a national standard electric bicycle for 50 kilometers. It has many advantages such as no charging and quick replacement. If the application of solid-state hydrogen storage tanks in electric bicycles is promoted, the demand for activation and hydrogen filling of solid-state hydrogen storage tanks will undoubtedly be huge.

[0003] In order to reduce the risk of hydrogen leakage, the small solid-state hydrogen storage tanks currently used in electric bicycles should generally be equipped with a manual switch valve in addition to a quick-connect plug. Users need to open the valve according to their needs when using it to establish a passage and drive the electric bicycle. Frequent manual opening and closing of the valve by users will reduce the user experience and further cause users to worry unnecessary about the safety of hydrogen-powered electric vehicles.

[0004] In addition, the main method of hydrogen filling or activation for this type of solid-state hydrogen storage tank with a switch valve is still to rely on manual connection of the pipeline to the solid-state hydrogen storage tank, which is inefficient. Workers must also strictly follow the operating procedures when operating to avoid safety problems.

[0005] In view of this, it is necessary to propose a solid-state hydrogen storage tank valve for electric bicycles that can be closed and stopped at any time and can activate multiple solid-state hydrogen storage tanks at one time, which is convenient for activation and hydrogen filling. Summary of the invention

[0006] The purpose of the present invention is to provide a solid-state hydrogen storage tank valve which can be turned off and on at any time when the driver leaves, is convenient for users to use, and can automatically charge and activate hydrogen.

[0007] In order to solve the above technical problems, the present invention discloses a solid-state hydrogen storage tank valve for electric bicycles that is convenient for activation and hydrogen filling, which is used to be installed on the top of the solid-state hydrogen storage tank, including a main valve body, the upper part of the main valve body has a quick-connect plug, the side of the main valve body has a knob for manually controlling the valve switch, the knob includes a shaft and a first knob and a second knob arranged on the shaft, the first knob is a gear, and the first knob is arranged between the second knob and the main valve body; the side of the main valve body is also provided with a bracket, one end of the bracket is connected to the main valve body, and the other end is provided with a guide device for guiding the valve connector of the hydrogen filling activation device to open or close the valve The guide device is arranged above the first knob, and a guide groove parallel to the axial direction of the solid hydrogen storage tank is provided on one side of the guide device near the first knob; the hydrogen charging and activation device has a plurality of valve connectors that can move up and down, and the valve connector has a connecting head and a rack matched with the first knob, and the connecting head and the rack are both arranged vertically downward; when the valve connector is connected to the valve, the connecting head and the rack move downward, and the connecting head and the quick-connect plug are sealed and connected. After the guide device guides the rack into the guide groove, the rack contacts the first knob to rotate the first knob, thereby opening the valve. After the hydrogen charging or activation is completed, the rack moves upward to close the valve.

[0008] Preferably, the upper portion of the guide groove has a guide portion, and the guide portion is wider than the lower portion of the guide groove.

[0009] Preferably, the guide portion is V-shaped.

[0010] Preferably, it also includes a driving device for driving the first knob to rotate, the driving device includes a transmission, a power device for providing driving force to the transmission, and a pressure sensor electrically connected to the power device, the transmission is detachably engaged with the first knob, and the pressure sensor is used to be installed on the seat of the electric bicycle.

[0011] Preferably, when the solid-state hydrogen storage tank is installed in an electric bicycle and the electric bicycle is in an open state, the driver sits on the seat of the electric bicycle, the pressure sensor is triggered, the power device starts, and the transmission drives the first knob to rotate, thereby opening the valve; the driver leaves or turns off the electric bicycle, the pressure sensor senses that the pressure disappears, the power device starts, and the transmission drives the first knob to rotate in the opposite direction, thereby closing the valve.

[0012] Preferably, the power device is an electric cylinder or an electromagnet, and the transmission device includes a transmission rack.

[0013] Preferably, the power device is an electric motor, and the transmission device comprises a transmission gear.

[0014] Preferably, the second knob has a diameter greater than that of the first knob.

[0015] Preferably, when the valve needs to be closed in an emergency, the second knob is manually turned to close the valve.

[0016] Preferably, when the driver leaves the seat of the electric bicycle and the pressure sensor senses that the pressure disappears, the power device starts to close the valve after a delay of 1-3 seconds.

[0017] The electric bicycle solid-state hydrogen storage tank valve that is convenient for activation and hydrogen charging of the present invention has at least the following advantages:

[0018] (1) When the hydrogen charging and activation device is used to charge or activate the solid hydrogen storage tank, due to the setting of the guide device, the rack of the hydrogen charging and activation device can be easily guided into the guide groove to contact the first knob so that the first knob can be rotated to open or close the valve. In the early connection process of hydrogen charging and activation, the quick-connect plug and the connector of the hydrogen charging and activation device can be connected and the valve can be opened only by a simple downward pressure action; after the rack of the hydrogen charging and activation device is lifted, the valve can be easily closed, which saves labor, reduces the safety hazards caused by manual operation, and improves efficiency and safety. This also provides a solution for the automated, intelligent, multi-channel and efficient activation and hydrogen charging of large quantities of solid hydrogen storage tanks.

[0019] (2) The driving device is linked with the seat of the electric bicycle, and the driver opens the valve after sitting on the seat, avoiding the trouble of manually opening the valve; and when the pressure sensor senses that the pressure disappears, it is triggered after a delay, which is conducive to filtering the bumps during driving and ensuring stable hydrogen output.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below through examples so that those skilled in the art can implement the invention with reference to the description.

[0025] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0026] like Figure 1 As shown, a solid-state hydrogen storage tank valve for electric bicycles that is convenient for activation and hydrogen charging is used to be installed on the top of the solid-state hydrogen storage tank, including a main valve body 1, the upper part of the main valve body 1 is provided with a quick-connect plug 2, the side of the main valve body 1 is provided with a knob for manually controlling the valve switch, the knob includes a shaft 3 and a first knob 4 and a second knob 5 arranged on the shaft 3, the first knob 4 is a gear, and the first knob 4 is arranged between the second knob 5 and the main valve body 1; the side of the main valve body 1 is also provided with a bracket 6, one end of the bracket 6 is connected to the main valve body 1, and the other end is provided with a guide device 7 for guiding the valve connector of the hydrogen charging activation device to open or close the valve; the guide device 7 is arranged above the first knob 4, and the side of the guide device 7 near the first knob 4 is provided with a guide groove 710 arranged parallel to the axial direction of the solid-state hydrogen storage tank; as shown Figure 2 As shown, the hydrogen charging and activation device has a plurality of valve connectors that can move up and down, and the valve connector has a connector 9 and a rack 10 that is compatible with the first knob 4, and the connector and the rack are both vertically arranged downward; when the valve connector is connected to the valve, the connector and the rack move downward, and the connector and the quick-connect plug 2 are sealed and connected, and after the guide device 7 guides the rack into the guide groove 710, the rack contacts the first knob 4 to rotate the first knob 4, thereby opening the valve, and after the hydrogen charging or activation is completed, the rack moves upward to close the valve.

[0027] The upper portion of the guide groove 710 has a guide portion 711 , and the width and thickness of the guide portion are greater than those of the lower portion of the guide groove 710 .

[0028] The guide portion 711 is V-shaped.

[0029] Further, such as Figure 3 As shown, it also includes a driving device 8 for driving the first knob 4 to rotate. The driving device 8 is installed in the electric bicycle. When the solid-state hydrogen storage tank is placed in the electric bicycle, the transmission is connected to the first knob 4 in a transmission manner. The driving device 8 includes a transmission 810, a power device 820 for providing driving force to the transmission, and a pressure sensor 830 electrically connected to the power device 820. The transmission 810 is detachably engaged with the first knob 4, and the pressure sensor 830 is used to be installed on the seat of the electric bicycle.

[0030] When the solid-state hydrogen storage tank is installed in an electric bicycle and the electric bicycle is in the open state, the driver sits on the seat of the electric bicycle, the pressure sensor 830 is triggered, the power device 820 starts, and the transmission drives the first knob 4 to rotate, thereby opening the valve. When the driver leaves or turns off the electric bicycle, the pressure sensor 830 senses that the pressure disappears, the power device 820 starts, and the transmission drives the first knob 4 to rotate in the opposite direction, thereby closing the valve.

[0031] The power device 820 is an electric cylinder or an electromagnet, and the transmission device includes a transmission rack; or the power device 820 is a motor, and the transmission device includes a transmission gear (in this embodiment, the transmission device adopts a transmission rack).

[0032] The diameter of the second knob 5 is larger than that of the first knob 4, so that the second knob 5 can be turned manually. In addition, if a large number of turns are required to close or open the valve, the first knob 4 can be processed on the shaft 3 in the form of an annular groove, so that the diameter of the first knob 4 is smaller than that of the shaft 3, so that the first knob 4 can be turned a large number of times. In an emergency, when the valve needs to be closed or the driving device 8 is damaged, the second knob 5 is manually turned to close the valve.

[0033] When the driver leaves the seat of the electric bicycle, the pressure sensor 830 senses that the pressure disappears, and after a delay of 1-3 seconds, the power device 820 starts to close the valve. When the pressure sensor 830 senses that the pressure disappears, it is triggered after a delay to prevent the drive device 8 from responding too quickly, which is beneficial to filtering the bumps during driving so that the hydrogen can be output stably.

[0034] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the embodiments shown and described herein.
