Description

Technical Field

[0001] The present application relates generally to the technical field of tool kits, and more particularly to tool kits for operating storage bottles, such as hydrogen storage bottles. Background Art

[0002] Storage bottles (also referred to as storage tanks) are widely used in various industries and are used as storage containers to store various materials. Storage bottles generally have a substantially cylindrical body. In many scenarios such as factories and construction sites, the storage bottle needs to be operated to adjust its position and / or rotational orientation around the axis of the bottle body. Taking hydrogen storage bottles as an example, hydrogen storage bottles can be used in hydrogen storage systems (Hydrogen Storage System, HSS) to store hydrogen. In scenarios such as assembly plants or maintenance plants, operators need to assemble hydrogen storage bottles into brackets of hydrogen storage systems, and during assembly, the rotational orientation of hydrogen storage bottles around the axis of the bottle body needs to be adjusted. Gantry cranes are tools commonly used to operate hydrogen storage bottles. Operators use gantry cranes to hoist hydrogen storage bottles into brackets. This hoisting method is inefficient and easy to cause harm to operators, and there are greater safety risks. In addition, after the hydrogen storage bottle is hoisted into the bracket, the operator (for example, using a gantry crane or manpower) lifts and rotates the hydrogen storage bottle to adjust its rotational orientation around the axis of the bottle body. This adjustment method is time-consuming and labor-intensive, and is also prone to causing harm to the operator, posing a greater safety risk.

[0076] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the following embodiments, for the convenience of description, the tool kit according to the present application is used to operate a hydrogen storage bottle as an example to introduce the tool kit. However, it should be understood that this example does not mean that any limitation is formed on the tool kit of the present application, and the tool kit according to the present application can also be used to operate any other suitable type of storage bottle (such as any solid, liquid and gas storage bottle). In addition, the various features in the various embodiments of the present application can be combined with each other without conflict.

[0077] Figures 1A to 1D The assembly process of assembling a hydrogen storage bottle 10 into a bracket 20 of a hydrogen storage system (HSS) using a tool kit 1 according to some embodiments of the present application is schematically depicted. The hydrogen storage system may be a vehicle-mounted hydrogen storage system for installation on a vehicle, and accordingly, the bracket 20 assembled with the hydrogen storage bottle 10 will be installed on the vehicle. The tool kit 1 includes a transport vehicle 100 configured to transport the hydrogen storage bottle 10, and a support assembly 200 and a positioning assembly 300 configured to be installed on the bracket 20 to operate the hydrogen storage bottle 10.

[0078] like Figures 1A to 1DAs shown, the bracket 20 can be configured for a hydrogen storage system to accommodate and hold the hydrogen storage bottle 10. The bracket 20 can be formed by a crossbar 21 and a column 22 that are fixed together (for example, by welding or riveting). The column 22 can extend substantially perpendicular to the crossbar 21. The column 22 is oriented in a manner substantially parallel to the gravity direction X, and the crossbar 21 is oriented in a manner substantially perpendicular to the gravity direction X. As used herein, the term "substantially parallel to" means precisely parallel to or parallel to with a deviation within 10°, and the term "substantially perpendicular to" means precisely perpendicular to or perpendicular to with a deviation within 10°.

[0079] The bracket 20 may define a housing space for housing the hydrogen storage bottle 10. The housing space may be defined by the crossbar 21 and the column 22 of the bracket 20. For example, Figure 1A and Figure 1B As shown, the bracket 20 defines two first accommodating spaces 20a at a first height (first layer), two second accommodating spaces 20b at a second height (second layer), and two third accommodating spaces 20c at a third height (third layer), wherein the third height is greater than the second height, and the second height is greater than the first height. For example, one of the two second accommodating spaces 20b can be located between the first crossbar 21a and the second crossbar 21b in the crossbar 21 and above the first crossbar 21a and the second crossbar 21b, and the other can be located between the second crossbar 21b and the third crossbar 21c in the crossbar 21 and above the second crossbar 21b and the third crossbar 21c. The first crossbar 21a, the second crossbar 21b, and the third crossbar 21c can be arranged in a manner parallel to each other and substantially perpendicular to the gravity direction X.

[0080] The hydrogen storage bottle 10 may also be referred to as a hydrogen storage bottle or a hydrogen storage tank, which is a container for storing hydrogen in a hydrogen storage system. The hydrogen storage bottle 10 may be made of any suitable material such as steel, and may have any suitable specifications and dimensions. The weight of the hydrogen storage bottle 10 is generally not less than 50 kg, and may be between 50 kg and 150 kg, and may even reach 200 kg or more. Figure 1A As best shown, the hydrogen storage bottle 10 includes a substantially cylindrical body 11. The body 11 defines a longitudinal center axis 12. The longitudinal center axis 12 is the axis of the cylinder. The body 11 has a side surface 13 extending circumferentially around the longitudinal center axis 12, and a first end 14a and a second end 14b opposite to each other in a direction YY along the longitudinal center axis 12. A valve member (not shown) such as a bottle mouth can be provided at the first end 14a and / or the second end 14b to provide a connection from the interior of the hydrogen storage bottle 10 to the pipeline of the hydrogen storage system.

[0081] In a scenario such as an assembly plant or a maintenance plant, an operator needs to perform the following operations on the hydrogen storage bottle 10: (i) transport the hydrogen storage bottle 10 from a location away from the bracket 20 to the bracket 20; (ii) adjust (e.g., preliminarily and roughly adjust) the rotational orientation of the hydrogen storage bottle 10 around the longitudinal center axis 12 before placing the hydrogen storage bottle 10 in a corresponding accommodation space (e.g., the first accommodation space 20a; the second accommodation space 20b or the third accommodation space 20c) of the bracket 20 (note that this step may be optional); (iii) place the hydrogen storage bottle 10 in the corresponding accommodation space of the bracket 20; and (iv) adjust (e.g., precisely adjust) the rotational orientation of the hydrogen storage bottle 10 around the longitudinal center axis 12 after placing the hydrogen storage bottle 10 in the corresponding accommodation space of the bracket 20. The operator can efficiently and safely perform the above operations on the hydrogen storage bottle 10 using the tool kit 1 according to the present application. When the hydrogen storage bottle 10 is placed in the second accommodation space 20b, the first crossbar 21a, the second crossbar 21b and the third crossbar 21c may be substantially parallel to the direction YY along the longitudinal center axis 12. The tool kit 1 will be described in detail below.

[0082] Transporter

[0083] The tool kit 1 includes a transporter 100 configured to transport a hydrogen storage bottle 10. The transporter 100 can be used in a scene such as an assembly plant or a maintenance plant to transport the hydrogen storage bottle 10 from a location away from the rack 20 to the rack 20, adjust the rotational orientation of the hydrogen storage bottle 10 about the longitudinal center axis 12 before placing the hydrogen storage bottle 10 in a corresponding accommodation space of the rack 20, and place the hydrogen storage bottle 10 in a corresponding accommodation space of the rack 20.

[0084] Please continue to see Figure 1A and Figure 1B , a hydrogen storage bottle 10 has been placed in one of the second accommodation spaces 20b of the support 20 and is fixed relative to the support 20 (this will be described in detail below). In addition, another hydrogen storage bottle 10 is loaded on the transport vehicle 100, which is to be placed in another second accommodation space 20b of the support 20. Figure 1C As shown, the transport vehicle 100 is locked to the bracket 20 so that the hydrogen storage bottle 10 on the transport vehicle 100 is aligned with the corresponding second accommodation space 20b of the bracket 20 for accommodating the hydrogen storage bottle 10. Figure 1D As shown, the transport vehicle 100 is still locked to the bracket 20, and the hydrogen storage cylinder 10 is being transferred from the transport vehicle 100 to the corresponding second accommodation space 20b of the bracket 20 to be placed in the corresponding second accommodation space 20b.

[0085] The following will further combine Figures 2A to 5C The configuration of the transport vehicle 100 will be described in detail. Figure 2A and Figure 2B 1 is a perspective view schematically illustrating a transport vehicle 100 on which a hydrogen storage cylinder 10 is loaded. Figure 2C It is along Figure 2A A cross-sectional view taken along line II in FIG. Figure 2D and Figure 2E A perspective view and a top view of the transport vehicle 100 are schematically depicted, respectively, but with the hydrogen storage bottles 10 removed to show details on the top side of the transport vehicle 100 .

[0086] In some embodiments, FIG. 2A to FIG. 2E As shown, the transport vehicle 100 may be a manual transport vehicle that is moved by pushing and / or pulling. The construction of the transport vehicle 100 will be described below in conjunction with an embodiment in which the transport vehicle 100 is a manual transport vehicle. However, it should be understood that the transport vehicle 100 is not limited thereto and may be a motorized (e.g., electric) transport vehicle or any other suitable type of transport vehicle.

[0087] The transport vehicle 100 includes a frame 110 having a top side 111 and a bottom side 112. The top side 111 and the bottom side 112 are opposite to each other in the gravity direction X. Although the frame 110 is shown in the figure as being formed by a plurality of rods, it should be understood that the frame 110 is not limited thereto and can be any suitable type of frame. Wheels 113 can be mounted on the bottom side 112 of the frame 110 to enable the transport vehicle 100 to move on various surfaces such as the floor of an assembly plant. As used herein, the term "wheel" refers to any suitable moving mechanism that supports the movement of the transport vehicle 100 on various surfaces.

[0088] like FIG. 2C to FIG. 2E As best shown, the transport vehicle 100 also includes a plurality of first universal ball bearing members 410 disposed on the top side 111 of the vehicle frame 110. Figures 1A to 1D and FIG. 2A to FIG. 2EAs shown, these first universal ball bearing members 410 are constructed and arranged to support the body 11 of the hydrogen storage bottle 10 on the side surface 13 of the body 11 to: (i) orient the body 11 in a manner that the longitudinal center axis 12 is substantially perpendicular to the gravity direction X; (ii) restrict the movement of the body 11 in a lateral direction ZZ that is substantially perpendicular to both the gravity direction X and the longitudinal center axis 12; and (iii) enable the body 11 to rotate around the longitudinal center axis 12 and translate along the direction YY of the longitudinal center axis 12. That is, when the side surface 13 of the body 11 of the hydrogen storage bottle 10 is supported on these first universal ball bearing members 410 of the transport vehicle 100, the body 11 is oriented in a manner that the longitudinal center axis 12 is substantially perpendicular to the gravity direction X. The first universal ball bearing members 410 support the bottle body 11 so that the bottle body 11 can rotate around the longitudinal center axis 12 and translate along the direction YY of the longitudinal center axis 12, and limit the movement of the bottle body 11 in the transverse direction ZZ. Here, the movement may include translation and rolling. In other words, the first universal ball bearing members 410 limit the movement of the bottle body 11 in the transverse direction ZZ, so that the bottle body 11 has no displacement component along the transverse direction ZZ.

[0089] By this configuration, when the hydrogen storage bottle 10 is loaded on the transporter 100, the hydrogen storage bottle 10 can be oriented in such a manner that the longitudinal center axis 12 is substantially perpendicular to the gravity direction X (i.e., the hydrogen storage bottle 10 is arranged substantially horizontally), and the hydrogen storage bottle 10 is allowed to rotate around the longitudinal center axis 12 and translate along the direction YY of the longitudinal center axis 12. The transporter 100 having the plurality of first universal ball bearing members 410 can be used to load the hydrogen storage bottle 10 to transport the hydrogen storage bottle 10 from a position away from the rack 20 to the rack 20, and allows the rotational orientation of the hydrogen storage bottle 10 around its longitudinal center axis 12 to be adjusted before the hydrogen storage bottle 10 is placed in the corresponding accommodation space of the rack 20, and can be used to transfer the hydrogen storage bottle 10 to the corresponding accommodation space of the rack 20 by translating the hydrogen storage bottle 10 along the direction YY of the longitudinal center axis 12.

[0090] Compared to using a gantry crane to transport the hydrogen storage bottle 10, using a transport vehicle 100 having such a configuration enables the hydrogen storage bottle 10 to be operated more efficiently and safely to adjust its position and rotational orientation around the longitudinal center axis 12. Since there is no need to arrange a gantry crane on the transport path, the transport vehicle 100 can improve the operational flexibility and efficiency of transporting the hydrogen storage bottle 10 and reduce costs. In addition, the transport vehicle 100 having such a configuration makes it easy to adjust the rotational orientation of the hydrogen storage bottle 10 around its longitudinal center axis 12 without requiring an operator to lift the hydrogen storage bottle 20, thereby improving the efficiency and safety of the assembly process.

[0091] FIG. 5A to FIG. 5C One of the first universal ball bearing components 410 of the transport vehicle 100 is schematically shown. FIG. 5A to FIG. 5C As shown, the first universal ball bearing member 410 includes a mounting seat 411, two bearing seats 412 and two balls 413. The two bearing seats 412 are arranged on the mounting seat 411, and each ball 413 is arranged in a corresponding one of the bearing seats 412.

[0092] The mounting base 411 is configured to be mounted on a base surface. As used in this application, the term "base surface" refers to any surface on which a universal ball bearing member can be mounted, such as a mounting surface on the top side 111 of the transport vehicle 100. The mounting base 411 can have any suitable fixing features that facilitate fixing the first universal ball bearing member 410 to the base surface.

[0093] Each support seat 412 is disposed on the mounting seat 411. The mounting seat 411 and the support seat 412 may have any suitable fixing features that facilitate fixing them relative to each other. Figure 5B As shown, the mounting seat 411 may have a mounting hole 411a, and the support seat 412 may have a mounting hole 412a. The mounting hole 411a of the mounting seat 411 may be aligned with the corresponding mounting hole 412a of the support seat 412, and a bolt (not shown) may be provided through the mounting hole 411a and the mounting hole 412a to fix the support seat 412 to the mounting seat 411.

[0094] Each support seat 412 is formed with a circular hole 412b. Figure 5CAs best shown, each ball 413 is held in a corresponding support seat 412 so that a portion of the ball 413 extends from a circular hole 412b of the support seat 412 for engaging the side surface 13 of the bottle body 11. The circular hole 412b of the support seat 412 is configured so that the portion of the ball 413 extending from the circular hole 412b is less than half of the ball 413 (i.e., less than a hemisphere) so that the ball 413 is securely held in the support seat 412. The ball 413 is able to freely rotate around its spherical center 413a. That is, the ball 413 of the first universal ball support member 410 is in rolling contact with the side surface 13 of the bottle body 11. The contour of the great circle of the ball 413 (i.e., the cross section of the ball 413 passing through the spherical center 413a) is circumscribed to the circular contour of the side surface 13 of the bottle body 11. When the side surface 13 of the bottle body 11 of the hydrogen storage bottle 10 is supported on the first universal ball support member 410 of the transport vehicle 100, by means of this rolling contact, the bottle body 11 can rotate around the longitudinal center axis 12 on the first universal ball support member 410 and translate along the direction YY of the longitudinal center axis 12.

[0095] Exemplarily, the shape of the inner wall 412c of the support seat 412 can be designed to match the shape of the portion of the ball 413 disposed in the support seat 412, so that the ball 413 can rotate freely around the ball center 413a. The material of the inner wall 413c can be selected to be wear-resistant and facilitate the free rotation of the ball 413 around the ball center 413a. Optionally, a plurality of small balls (not shown, and the small balls can also be referred to as circulating balls) can be provided between the inner wall 412c of the support seat 412 and the portion of the ball 413 disposed in the support seat 412 to reduce the friction between the inner wall 412c of the support seat 412 and the ball 413, thereby facilitating the free rotation of the ball 413 around its ball center 413a.

[0096] like Figure 5C As shown, the circular hole 412b of each support seat 412 of the first universal ball support member 410 defines a central axis 412d. In some embodiments, the central axis 412d can extend through the ball center 413a of the ball 413 held in the support seat 412. Figure 2CAs shown, the plurality of first universal ball bearing members 410 are constructed and arranged so that when the bottle body 11 of the hydrogen storage bottle 10 is supported on the plurality of first universal ball bearing members 410, the central axis 412d of the circular hole 412b of each support seat 412 of each first universal ball bearing member 410 perpendicularly intersects with the longitudinal central axis 12 of the bottle body 11. In other words, the central axis 412d of the circular hole 412b of each support seat 412 of each first universal ball bearing member 410 extends through the ball center 413a of the ball 413 held in the support seat 412, and perpendicularly intersects with the longitudinal central axis 12 of the bottle body 11. With this configuration, it is possible to optimize the support of the bottle body 11 of the hydrogen storage bottle 10 by the first universal ball bearing member 410 to facilitate the rotation of the bottle body 11 around the longitudinal central axis 12 and the translation in the direction YY along the longitudinal central axis 12.

[0097] like Figure 5B and Figure 5C As shown, for each first universal ball bearing member 410, the mounting seat 411 includes a support surface 411b and a bottom surface 411c. In some embodiments, the bottom surface 411c of the mounting seat 411 can be flat for being arranged on a flat base surface. Each support seat 412 is arranged on the support surface 411b of the mounting seat 411. The support surface 411b of the mounting seat 411 can be inclined relative to the bottom surface 411c so that the center axis 412d of the circular hole 412b of each support seat 412 arranged on the mounting seat 411 is oriented obliquely relative to the bottom surface 411c. Through this configuration, when the mounting seat 411 is arranged on a flat base surface and the bottle body 11 is supported on the first universal ball bearing member 410, the center axis 412d of the circular hole 412b of each support seat 412 of the first universal ball bearing member 410 can be perpendicularly intersected with the longitudinal center axis 12 of the bottle body 11 and oriented obliquely relative to the base surface. This makes it possible to optimize the support of the bottle body 11 of the hydrogen storage bottle 10 by the first universal ball bearing member 410, thereby reliably restricting the movement of the bottle body 11 in the transverse direction ZZ.

[0098] The support seat 412 may include a top surface 412e and a bottom surface 412f, and the circular hole 412b may be formed at the top surface 412e. The top surface 412e and the bottom surface 412f face opposite to each other in a direction along the central axis 412d of the circular hole 412b. The bottom surface 412f of the support seat 412 is disposed on the support surface 411b of the mounting seat 411. In some embodiments, the support surface 411b of the mounting seat 411 and the bottom surface 412f of the support seat 412 may be flat. The flat bottom surface 412f of the support seat 412 is disposed on the flat support surface 411b of the mounting seat 411. In one of these embodiments, as Figure 5CAs best shown, the mounting seat 411 can be configured such that the central axis 412d of the circular hole 412b is perpendicular to the bottom surface 412f, and when the support seat 412 is disposed on the mounting seat 411, the central axis 412d of the circular hole 412b is perpendicular to the support surface 411b of the mounting seat 411. With this configuration, the force transmission from the support seat 412 to the mounting seat 411 can be optimized, so that the force applied by the hydrogen storage bottle 10 to the ball 413 is transmitted to the mounting seat 411 via the support seat 412 in a direction perpendicular to the support surface 411b of the mounting seat 411.

[0099] In some embodiments, FIG. 2C to FIG. 2E As shown, the top side 111 of the frame 110 of the transport vehicle 100 may have a flat mounting surface 111a, which is used as a base surface for setting the first universal ball support member 410. The mounting surface 111a extends substantially perpendicular to the gravity direction X. The bottom surface 411c of the mounting seat 411 of the first universal ball support member 410 is set on the mounting surface 111a. In addition, as described above, the support surface 411b of the mounting seat 411 may be inclined relative to the bottom surface 411c so that the center axis 412d of the circular hole 412b of each support seat 412 set on the mounting seat 411 is oriented obliquely relative to the bottom surface 411c. Although the mounting surface 111a of the frame 110 is FIG. 2C to FIG. 2E 110 is shown in the form of a plurality of mounting plates on the top side 111 of the frame 110, and each first universal ball bearing member 410 is disposed on a corresponding mounting plate, but it should be understood that the present application is not limited thereto. For example, the mounting surface 111a of the frame 110 may be a continuous flat surface.

[0100] Despite FIG. 5A to FIG. 5C It is shown that for each first universal ball bearing member 410, two groups of bearing seats 412 and balls 413 are provided on the same mounting seat 411, but it should be understood that the configuration of the first universal ball bearing member 410 is not limited thereto. In other embodiments, the first universal ball bearing member 410 may include a single group of bearing seats 412 and balls 413 on the same mounting seat 411, or may include more than two groups of bearing seats 412 and balls 413 on the same mounting seat 411.

[0101] In addition, although it is described above that the first universal ball bearing member 410 includes the mounting seat 411, in some other embodiments, the first universal ball bearing member 410 may not have the mounting seat 411, but the supporting seat 412 is directly disposed on a base surface, for example, directly disposed on a base surface on the top side 111 of the vehicle frame 110. In this case, the base surface may extend obliquely so that the central axis 412d of the circular hole 412b of the supporting seat 412 disposed thereon is obliquely oriented to perpendicularly intersect with the longitudinal central axis 12 of the bottle body 11.

[0102] like Figure 2C As best shown, when the body 11 of the hydrogen storage bottle 10 is supported on the plurality of first universal ball bearing members 410, that is, when the body 11 is oriented with the longitudinal center axis 12 substantially perpendicular to the gravity direction X, the side surface 13 of the body 11 may include an upper half 13a and a lower half 13b defined by the gravity direction X. Figure 2C The upper half 13a of the side surface 13 of the bottle body 11 is located above the lower half 13b, which is divided by an imaginary plane P1 perpendicular to the gravity direction X and passing through the longitudinal center axis 12. The cross-sectional profiles of the upper half 13a and the lower half 13b perpendicular to the longitudinal center axis 12 are both semicircular. It should be understood that the upper half 13a and the lower half 13b are relative concepts. When the bottle body 11 rotates around the longitudinal center axis 12, the actual parts corresponding to the upper half 13a and the lower half 13b will also change accordingly.

[0103] In some embodiments, Figure 2C and Figure 2E As shown, the plurality of first universal ball bearing members 410 include a first group R1 of first universal ball bearing members 410 and a second group R2 of first universal ball bearing members 410. The first group R1 and the second group R2 are constructed and arranged to support the lower half 13b of the side surface 13 of the bottle body 11 on both sides of the longitudinal center axis 12 of the bottle body 11, respectively. Figure 2E The bottle body 11 is not shown in the figure, but the position and direction of the longitudinal center axis 12 of the bottle body 11 when the bottle body 11 is supported on the plurality of first universal ball support members 410 are schematically indicated by dotted lines.

[0104] like Figure 2EAs best shown, the first group R1 includes five first universal ball bearing members 410, and the second group R2 also includes five first universal ball bearing members 410. It should be understood that the present application is not limited thereto, and each of the first group R1 and the second group R2 may include at least one (e.g., one, two, three, four, five, or more) first universal ball bearing member 410. In addition, it should be understood that the number of first universal ball bearing members 410 in the first group R1 and the number of first universal ball bearing members 410 in the second group R2 may be the same or different.

[0105] In one of these embodiments, Figure 2C and Figure 2E As best shown, each first universal ball bearing member 410 in the first group R1 may be aligned with each other and spaced apart from each other in a direction substantially parallel to the longitudinal center axis 12 of the bottle body 11. In other embodiments, each first universal ball bearing member 410 in the first group R1 may not be aligned with each other in a direction substantially parallel to the longitudinal center axis 12 of the bottle body 11, but may be staggered from each other in a direction substantially parallel to the longitudinal center axis 12 along the contour of the lower half 13b of the side surface 13 of the bottle body 11.

[0106] In one of these embodiments, each first universal ball bearing member 410 in the first group R1 may have the same structure as each other. In other embodiments, each first universal ball bearing member 410 in the first group R1 may have a different structure from each other. For example, the ball size and / or number of each first universal ball bearing member 410 in the first group R1 may be different, the arrangement of the ball and the bearing seat on the mounting seat may be different, the size of the mounting seat may be different, the inclination angle of the support surface of the mounting seat relative to the bottom surface may be different, and so on.

[0107] In one of these embodiments, Figure 2C and Figure 2E As best shown, each first universal ball bearing member 410 in the second group R2 may be aligned with each other and spaced apart from each other in a direction substantially parallel to the longitudinal center axis 12 of the bottle body 11. In other embodiments, each first universal ball bearing member 410 in the second group R2 may not be aligned with each other in a direction substantially parallel to the longitudinal center axis 12 of the bottle body 11, but may be staggered from each other in a direction substantially parallel to the longitudinal center axis 12 along the contour of the lower half 13b of the side surface 13 of the bottle body 11.

[0108] In one of these embodiments, each first universal ball bearing member 410 in the second group R2 may have the same structure as each other. In other embodiments, each first universal ball bearing member 410 in the second group R2 may have a different structure from each other. For example, the ball size and / or number of each first universal ball bearing member 410 in the second group R2 may be different, the arrangement of the ball and the bearing seat on the mounting seat may be different, the size of the mounting seat may be different, the inclination angle of the support surface of the mounting seat relative to the bottom surface may be different, and so on.

[0109] In one of these embodiments, the first group R1 and the second group R2 may be arranged symmetrically with respect to the longitudinal center axis 12 of the bottle body 11. This can make the supporting force on the bottle body 11 more uniform, thereby improving the stability of the bottle body 11 on the transport vehicle 100. In other embodiments, the first group R1 and the second group R2 may not be arranged symmetrically with respect to the longitudinal center axis 12 of the bottle body 11.

[0110] In one of these embodiments, the spacing between the first group R1 and the second group R2 is adjustable so that bottles 11 with different sizes (diameters) can be supported between the first group R1 and the second group R2, thereby enabling the same transport vehicle 100 to load bottles 11 with different sizes (diameters). In other words, bottles 11 of various specifications can share the same transport vehicle 100. For example, Figure 5B As shown, the mounting seat 411 of the first universal ball bearing member 410 may include a slot-shaped mounting hole 411d so that the position of the mounting seat 411 on the mounting surface 111a of the top side 111 of the frame 110 along the transverse direction ZZ can be adjusted. For another example, the position of the mounting surface 111a of the top side 111 of the frame 110 may be adjustable so that the position of the mounting seat 411 disposed thereon along the transverse direction ZZ can be adjusted. It should be understood that the first universal ball bearing member 410 and / or the frame 110 may have any suitable mechanism so that the spacing between the first group R1 and the second group R2 can be adjusted.

[0111] In some embodiments, the frame 110 may further include a lifting mechanism (not shown) that is constructed and arranged to be able to adjust the distance between the top side 111 and the bottom side 112 in the gravity direction X. Through this configuration, the height of the hydrogen storage bottle 10 loaded by the transport vehicle 100 can be adjusted so that the hydrogen storage bottle 10 can be aligned with the corresponding accommodation space of the bracket 20. Exemplarily, the lifting mechanism may be a hydraulic lifting mechanism that is connected between the top side 111 and the bottom side 112 of the frame 110 to adjust the distance between the top side 111 and the bottom side 112 in the gravity direction X.

[0112] In some other embodiments, a plurality of frames 110 of different heights may be designed according to the different heights of the accommodation spaces of the bracket 20 .

[0113] In some embodiments, the frame 110 may further include a longitudinal limiting mechanism, which is constructed and arranged to limit the translation of the bottle body 11 along the direction YY of the longitudinal center axis 12 when the bottle body 11 of the hydrogen storage bottle 10 is supported on the plurality of first universal ball bearing members 410. For example, in the case of emergency braking or sudden acceleration of the transport vehicle 100, the hydrogen storage bottle 10 may accidentally translate along the direction YY of the longitudinal center axis 12. By equipping the transport vehicle 110 with such a longitudinal limiting mechanism, the reliability of the transport vehicle 110 and the safety of the transportation process can be improved.

[0114] In one of these embodiments, Figure 2A , Figure 2B and Figure 2D As best shown, the longitudinal limiting mechanism may include a first lever 114a and a second lever 114b. The first lever 114a and the second lever 114b are arranged at opposite ends of the top side 111 of the frame 110 in the direction YY along the longitudinal center axis 12 to engage with the first end 14a and the second end 14b of the bottle body 11, respectively, so as to limit the translation of the bottle body 11 along the direction YY of the longitudinal center axis 12. It should be understood that the longitudinal limiting mechanism is not limited thereto, but may be in any suitable form to limit the translation of the bottle body 11 along the direction YY of the longitudinal center axis 12.

[0115] In some embodiments, the frame 110 may further include a transverse limiting mechanism, which is constructed and arranged to limit the movement of the bottle body 11 along the transverse direction ZZ over the multiple first universal ball bearing members 410 when the bottle body 11 of the hydrogen storage bottle 10 is supported on the multiple first universal ball bearing members 410. For example, when the transport vehicle 100 passes through a large ditch and causes the hydrogen storage bottle 10 to shake, the hydrogen storage bottle 10 may move along the transverse direction ZZ over the multiple first universal ball bearing members 410. By equipping such a transverse limiting mechanism, the reliability of the transport vehicle 110 and the safety of the transportation process can be improved.

[0116] In one of these embodiments, Figure 2A , Figure 2B and Figure 2DAs best shown, the transverse limiting mechanism may include a third gear rod 114c and a fourth gear rod 114d. The third gear rod 114c and the fourth gear rod 114d are arranged at two opposite sides of the top side 111 of the frame 110 in the transverse direction ZZ to limit the movement of the bottle body 11 over the first group R1 first universal ball bearing member 410 and the second group R2 first universal ball bearing member 410 along the transverse direction ZZ. Exemplarily, the third gear rod 114c and the fourth gear rod 114d may be connected between the first gear rod 114a and the second gear rod 114b, respectively. It should be understood that the transverse limiting mechanism is not limited thereto, but may be in any suitable form to limit the movement of the bottle body 11 over the plurality of first universal ball bearing members 410 along the transverse direction ZZ.

[0117] In some embodiments, the transport cart 100 may include a locking feature, and the bracket 20 may include a complementary locking feature, which may be constructed and arranged to cooperate with each other to enable the transport cart 100 to be locked and released relative to the bracket 20. Through this configuration, the transport cart 100 can be prevented from being accidentally moved during the movement of the hydrogen storage bottle 10 from the transport cart 100 to the corresponding accommodation space of the bracket 20.

[0118] In some embodiments, the transport cart 100 may include a guide feature and the bracket 20 may include a complementary guide feature, which may be constructed and arranged to cooperate with each other to enable the transport cart 100 to be aligned with the corresponding receiving space defined by the bracket 20.

[0119] For example, Figure 4 As shown, the transporter 100 may include a latch 115 located at the front of the bottom side 112, and as shown in FIG. Figure 3 As shown, the bracket 20 may include a latch receiving portion 23. The latch 115 may be used as a locking feature and a guide feature, and the latch receiving portion 23 may be used as a complementary locking feature and a complementary guide feature. Specifically, when the latch 115 is engaged with the latch receiving portion 23, the transport vehicle 100 can be locked relative to the bracket 20, and the transport vehicle 100 can be aligned with the corresponding accommodation space defined by the bracket 20. When the latch 115 is disengaged from the latch receiving portion 23, the transport vehicle 100 can be unlocked relative to the bracket 20. It should be understood that the locking feature and the complementary locking feature and / or the guide feature and the complementary guide feature are not limited thereto, but may be in any suitable form.

[0120] The operator can use the transport vehicle 100 to transport the hydrogen storage bottle 10 from a position away from the support 20 to the support 20. Figure 1CAs shown, the transport vehicle 100 is locked relative to the bracket 20 by, for example, the latch 115 and the latch receiving portion 23, and the hydrogen storage bottle 10 loaded on the transport vehicle 100 is aligned with the second accommodation space 20b of the bracket 20. Since the hydrogen storage bottle 10 is supported on the plurality of first universal ball support members 410, the operator can adjust the rotational orientation of the hydrogen storage bottle 10 by rotating the bottle body 11 around the longitudinal center axis 12 before placing the hydrogen storage bottle 10 in the second accommodation space 20b of the bracket 20. Subsequently, as shown in FIG. Figure 1D As shown, the lateral limiting mechanism (e.g., the first gear lever 114a) can be removed, and the hydrogen storage bottle 10 can be translated on the plurality of first universal ball bearing members 410 toward the second accommodation space 20b of the bracket 20. After the hydrogen storage bottle 10 is placed in the second accommodation space 20b, the transport vehicle 100 can be released relative to the bracket 20.

[0121] Although the above description is that the transporter 100 carries one hydrogen storage bottle 10, it should be understood that the transporter 100 can be configured to simultaneously carry multiple hydrogen storage bottles 10. In addition, although the above description is that the operator uses the transporter 100 to transport and place the hydrogen storage bottle 10 on the bracket 20, it should be understood that the operator can also use the transporter 100 to receive the removed hydrogen storage bottle 10 from the bracket 20 and transport it away.

[0122] Support components

[0123] The tool kit 1 includes a support assembly 200 configured to be mounted on the bracket 20 to support the hydrogen storage bottle 10 in a receiving space (e.g., the first receiving space 20a, the second receiving space 20b, or the third receiving space 20c) of the bracket 20. The support assembly 200 can be used to assist in transferring the hydrogen storage bottle 10 from the transport vehicle 100 or other mechanism to the corresponding receiving space of the bracket 20, and to adjust the rotational orientation of the hydrogen storage bottle 10 around the longitudinal center axis 12 after the hydrogen storage bottle 10 is placed in the corresponding receiving space of the bracket 20.

[0124] The following will be combined Figures 6 to 8D The configuration of the support assembly 200 will be described in detail. Figure 6 yes Figure 1A FIG. 2 is an enlarged view of area C in FIG. 2 , which schematically shows that three support assemblies 200 are mounted on the bracket 20. Although one of the support assemblies 200 is partially obscured by the column 22, it is conceivable that the three support assemblies 200 can have the same configuration as each other and can be mounted on the bracket 20 in the same manner. Therefore, only the following description will be made in conjunction with FIG. 7A to 8D The construction of one of the support assemblies 200 is described in detail. Fig. 7A and FIG. 7C to FIG. 7FThe support assembly 200 is schematically depicted in a state when it is mounted on the bracket 20, but in Fig. 7A and FIG. 7C to FIG. 7F The associated parts of the bracket 20 are omitted in order to clearly show the structure of the support assembly 200. Figure 7B is a partially exploded view of the support assembly 200, Figure 7G yes Figure 7F A magnified view of region D in FIG. 1 , and Figure 7H It is along Fig. 7A A cross-sectional view taken along line III-III in FIG.

[0125] like 7A to 7F As shown, the support assembly 200 includes a mounting mechanism 201 and a pair of second universal ball support members 420 disposed on the mounting mechanism 201 .

[0126] The mounting mechanism 201 can be configured to be detachably mounted on the bracket 20. That is, the mounting mechanism 201 can be removed from the bracket 20 in a non-destructive manner after being mounted on the bracket 20. Through this detachable configuration, the operator can reuse the support assembly 200. Exemplarily, the operator can assemble the mounting mechanism 201 to the bracket 20 and / or remove it from the bracket 20 without using any tools. As will be described in detail below, after assisting in transferring the hydrogen storage bottle 10 to a storage space of the bracket 20, the support assembly 200 can be removed from the storage space and set to another storage space of the same bracket 20 or other brackets to assist in placing another hydrogen storage bottle 10 in the other storage space. The mounting mechanism 201 can be any suitable mechanism that can be detachably mounted on the bracket 20 and on which the second universal ball bearing member 420 can be set.

[0127] The pair of second universal ball support members 420 are disposed on the mounting mechanism 201 and are constructed and arranged to support the bottle body 11 on the side surface 13 of the bottle body 11 of the hydrogen storage bottle 10 so as to: (i) orient the bottle body 11 in a manner in which the longitudinal center axis 12 is substantially perpendicular to the gravity direction X; (ii) limit the movement of the bottle body 11 in a lateral direction ZZ that is substantially perpendicular to both the gravity direction X and the longitudinal center axis 12; and (iii) enable the bottle body 11 to rotate around the longitudinal center axis 12 and translate in the direction YY of the longitudinal center axis 12.

[0128] Figure 1DIt is schematically shown that during the transfer of the hydrogen storage bottle 10 from the transport vehicle 100 to the second accommodation space 20b of the support 20, the bottle body 11 of the hydrogen storage bottle 10 is partially supported on the second universal ball bearing member 420 of the two support assemblies 200. The bottle body 11 of the hydrogen storage bottle 10 is oriented in a manner that the longitudinal center axis 12 is substantially perpendicular to the gravity direction X. The second universal ball bearing member 420 of the two support assemblies 200 supports the bottle body 11 so that the bottle body 11 can rotate around the longitudinal center axis 12 and translate along the direction YY of the longitudinal center axis 12, and restricts the movement of the bottle body 11 in the transverse direction ZZ that is substantially perpendicular to both the gravity direction X and the longitudinal center axis 12. Here, the movement may include translation and rolling. That is, the second universal ball bearing member 420 restricts the movement of the bottle body 11 in the transverse direction ZZ so that the bottle body 11 has no displacement component along the transverse direction ZZ.

[0129] In addition, as will be described in detail below, when the hydrogen storage bottle 10 is completely transferred from the transport vehicle 100 to the second accommodation space 20b of the bracket 20, Figure 6 The second universal ball bearing members 420 of the three bearing assemblies 200 shown support the bottle body 11 to enable the bottle body 11 to rotate around the longitudinal center axis 12 and translate along the direction YY of the longitudinal center axis 12, and limit the movement of the bottle body 11 in the transverse direction ZZ.

[0130] By means of the support assembly 200 having such a configuration, an operator can easily transfer the hydrogen storage bottle 10 from the transport vehicle 100 or other mechanisms to the corresponding accommodation space of the bracket 20, and can adjust the rotational orientation of the hydrogen storage bottle 10 around the longitudinal center axis 12 after placing the hydrogen storage bottle 10 in the corresponding accommodation space of the bracket 20. Since the mounting mechanism 201 is configured to be detachably mounted on the bracket 20, such a support assembly 200 can be reused. The support assembly 200 enables the hydrogen storage bottle 10 to be operated more efficiently and safely to adjust its position in the bracket 20 and the rotational orientation around the longitudinal center axis 12. In addition, the support assembly 200 having such a configuration enables the rotational orientation of the hydrogen storage bottle 10 around its longitudinal center axis 12 to be easily adjusted without requiring the operator to lift the hydrogen storage bottle 20, thereby improving the efficiency and safety of the assembly process.

[0131] like Figure 1DAs shown, a pair of second universal ball bearing members 420 of each supporting assembly 200 supports the side surface 13 of the bottle body 11 on both sides of the longitudinal center axis 12 respectively. One of the pair of second universal ball bearing members 420 can be grouped as a first group of universal ball bearing members, and the other can be grouped as a second group of universal ball bearing members. In other words, each supporting assembly 200 may include two groups of universal ball bearing members, and the number of universal ball bearing members in each group is one. It should be understood that the present application is not limited to this. In other partial embodiments, each supporting assembly 200 may include more than two second universal ball bearing members 420, and these second universal ball bearing members 420 may be grouped and arranged in any suitable manner.

[0132] like Fig. 7A and Figure 7B As shown, each second universal ball bearing member 420 may include a mounting seat 421, a support seat 422 and a ball 423. The structure of the second universal ball bearing member 420 may be substantially the same as that of the first universal ball bearing member 410, except that only one support seat 422 and one ball 423 are provided on the mounting seat 421 of the second universal ball bearing member 420. In addition, the arrangement of the second universal ball bearing member 420 on the mounting mechanism 201 may be the same as the arrangement of the first universal ball bearing member 410 on the vehicle frame 110. In addition, the cooperation mode of the second universal ball bearing member 420 and the bottle body 11 of the hydrogen storage bottle 10 may be the same as the cooperation mode of the first universal ball bearing member 410 and the bottle body 11 of the hydrogen storage bottle 10. Therefore, these identical parts will not be described in detail in the present application. Furthermore, it should be understood that in some other embodiments, similar to some exemplary forms of the first universal ball bearing component 410 described above, the second universal ball bearing component 420 may not have a mounting seat 421, but the bearing seat 422 is directly disposed on the base surface.

[0133] As described above and as Figure 1A and Figure 6 As shown, the second accommodation space 20b is located between and above the first crossbar 21a and the second crossbar 21b in the crossbar 21 of the bracket 20. The first crossbar 21a and the second crossbar 21b can be arranged parallel to each other and substantially perpendicular to the gravity direction X.

[0134] The mounting mechanism 201 of the support assembly 200 may be configured to be mounted on the first crossbar 21 a and the second crossbar 21 b of the crossbar 21 of the bracket 20 to support the hydrogen storage bottle 10 in the accommodation space of the bracket 20 .

[0135] In some embodiments, 7A to 7HAs shown, the mounting mechanism 201 may include a beam 210, a first mounting block 230, and a second mounting block 240. The second universal ball bearing member 420 is disposed on the beam 210. Figure 7B and Fig.7D As best shown, the beam 210 is elongated and includes a first end 211 and a second end 212 opposite to each other in the length direction LL, a top side 213 and a bottom side 214 opposite to each other in the thickness direction TT substantially perpendicular to the length direction LL, and a front side 215 and a rear side 216 opposite to each other in the width direction WW substantially perpendicular to both the length direction LL and the thickness direction TT. The beam 210 may be made of, for example, steel. The second universal ball bearing member 420 is disposed on the top side 213 of the beam 210. Exemplarily, the top side 213 of the beam 210 may include a flat mounting surface extending substantially perpendicular to the gravity direction X, and the second universal ball bearing member 420 is disposed on the flat mounting surface.

[0136] The first mounting block 230 is located at the first end 211 of the beam 210, and the second mounting block 240 is located at the second end 212 of the beam 210. The first mounting block 230 can be configured to be detachably disposed on the first crossbar 21a, and the second mounting block 240 is used to be detachably disposed on the second crossbar 21b to support the beam 210 between the first crossbar 21a and the second crossbar 21b so that the beam 210 is located Figure 6 With the help of the first mounting block 230 and the second mounting block 240 , the support assembly 200 can be easily mounted on the bracket 20 and removed from the bracket 20 , thereby achieving the reuse of the support assembly 200 .

[0137] The beam 210 may span the space between the first crossbar 21a and the second crossbar 21b. Figure 6 In the case of the installation position shown, the thickness direction TT is parallel to the gravity direction X, the width direction WW is parallel to the first crossbar 21a and the second crossbar 21b, and the length direction LL is perpendicular to the gravity direction X, the first crossbar 21a and the second crossbar 21b. The length of the beam 210 along the length direction LL is slightly less than the spacing between the first crossbar 21a and the second crossbar 21b.

[0138] In some embodiments, the first mounting block 230 and / or the second mounting block 240 may be integrally formed with the beam 210. In other embodiments, at least one of the first mounting block 230 and the second mounting block 240 is detachably coupled to the beam 210. That is, the beam 210 and at least one of the first mounting block 230 and the second mounting block 240 can be decoupled in a non-destructive manner. Exemplarily, the beam 210 and at least one of the first mounting block 230 and the second mounting block 240 can be decoupled and reconnected without using any tools.

[0139] Please refer back to Figures 1A to 1D and Figure 6 In some embodiments, the bracket 20 may further include a retaining seat 25 disposed in the second accommodating space 20b for placing and retaining the hydrogen storage bottle 20. Exemplarily, the retaining seat 25 may be supported in the second accommodating space 20b by the first cross bar 21a and the second cross bar 21b. The retaining seat 25 includes a supporting surface 25a for supporting the bottle body 11. The supporting surface 25a of the retaining seat 25 may support the bottle body 11 on the side surface 13 of the bottle body 11 so that the bottle body 11 can be oriented in a manner such that the longitudinal center axis 12 is substantially perpendicular to the gravity direction X.

[0140] like Figure 1D and Figure 6 As shown, during the transfer of the hydrogen storage bottle 10 from the transport vehicle 100 or other mechanism to the second accommodation space 20b of the bracket 20, the support assembly 200 is supported between the first crossbar 21a and the second crossbar 21b. The beam 210 is supported by the first mounting block 230 and the second mounting block 240. Figure 6 The support assembly 200 can be configured so that when the beam 210 is supported in the installation position and the bottle body 11 of the hydrogen storage bottle 10 is supported on the second universal ball support member 420, the side surface 13 of the bottle body 11 is located above the support surface 25a of the retaining seat 25 and is spaced apart from the support surface 25a, that is, the side surface 13 of the bottle body 11 does not contact the support surface 25a.

[0141] The support assembly 200 can also be configured so that at least the beam 210 can be moved from Figure 6The installation position shown is moved downward away from the second accommodation space 20b. Since the second universal ball bearing member 420 is disposed on the beam 210, the second universal ball bearing member 420 is also moved downward, thereby disengaging from the side surface 13 of the bottle body 11 and no longer supporting the bottle body 11. Since the support surface 25a of the retaining seat 25 is located below the bottle body 11, the bottle body 11 is seated on the support surface 25a and supported by the support surface 25a. In this way, the support assembly 200 is removed, and the hydrogen storage bottle 10 is supported by the retaining seat 25 in the second accommodation space 20b.

[0142] like Figure 1A and Figure 6 As shown, the bracket 20 may further include a clamp 26, which may be coupled to the holder 25. When the body 11 of the hydrogen storage bottle 20 is placed on the holder 25, the clamp 26 may be tightened and clamped on the body 11 to fix the body 11 on the holder 25, thereby reliably retaining the hydrogen storage bottle 20 in the second accommodating space 20b. In addition, the clamp 26 may be loosened to release the body 11, thereby allowing the hydrogen storage bottle 20 to be removed from the holder 25.

[0143] For example, in the case where the bracket 20 includes the retaining seat 25, the support assembly 200 is configured so that at least the beam 210 can be moved from Figure 6 The installation position shown is advantageously moved downward away from the second accommodation space 20 b. This enables the hydrogen storage bottle 10 to be transferred to the second accommodation space 20 b of the support 20 using the support assembly 200 and the rotational orientation of the hydrogen storage bottle 10 around the longitudinal center axis 12 to be adjusted, and then the hydrogen storage bottle 10 can be transferred to the holder 25 without changing or substantially changing the position and rotational orientation of the hydrogen storage bottle 10.

[0144] To this end, the beam 210, the first mounting block 230 and the second mounting block 240 of the support assembly 200 can be configured in such a manner that: (i) the first mounting block 230 is used to be detachably disposed on the first crossbar 21a, and the second mounting block 240 is used to be detachably disposed on the second crossbar 21b, so as to support the beam 210 between the first crossbar 21a and the second crossbar 21b. Figure 6 and (ii) at least one of the first mounting block 230 and the second mounting block 240 is detachably coupled to the beam 210, so that when the beam 210 is supported in the mounting position, the beam 210 can be moved downward from the mounting position away from the accommodation space by disconnecting the beam 210 from the at least one of the first mounting block 230 and the second mounting block 240. As described above, since the second universal ball bearing member 420 is disposed on the beam 210, the second universal ball bearing member 420 is also moved downward.

[0145] In some embodiments, the first mounting block 230 and the second mounting block 240 are both detachably coupled to the beam 210, so that when the beam 210 is supported in the mounting position, the beam 210 can be moved downward from the mounting position away from the second accommodation space 20b by disconnecting the beam 210 from both the first mounting block 230 and the second mounting block 240. Subsequently, since the first mounting block 230 and the second mounting block 240 are detachably disposed on the first crossbar 21a and the second crossbar 21b, respectively, the first mounting block 230 and the second mounting block 240 can be removed from the first crossbar 21a and the second crossbar 21b, and the beam 210, the first mounting block 230 and the second mounting block 240 can be assembled together again for reuse.

[0146] In other partial embodiments, only one of the first mounting block 230 and the second mounting block 240 is detachably coupled to the beam 210, so that when the beam 210 is supported in the mounting position, the beam 210 and the other mounting block (the other mounting block is detachably disposed on the corresponding cross bar) can be moved downward from the mounting position away from the second accommodating space 20b by disconnecting the beam 210 from the one mounting block. Subsequently, the one mounting block can be removed from the corresponding cross bar of the first cross bar 21a and the second cross bar 21b and assembled with the beam 210 and the other mounting block for reuse. The other mounting block can be a part formed integrally with the beam 210, or can be non-detachably coupled to the beam 210.

[0147] The following describes exemplary forms of the beam 210 , the first mounting block 230 , and the second mounting block 240 by taking at least the first mounting block 230 being detachably coupled to the beam 210 as a specific example. It should be understood that the present application is not limited thereto.

[0148] like Figure 7B As shown, the beam 210 may also have a first end surface 211a at the first end 211, and a first hinge portion 221 extending from the first end surface 211a along the length direction LL. The first hinge portion 221 protrudes from the first end surface 211a along the length direction LL. The first hinge portion 221 is formed with a first hinge hole 221a extending along the width direction WW. The first hinge hole 221a extends through the first hinge portion 221 along the width direction WW. Figure 7H As best shown, the first hinge portion 221 includes a top surface 221b and a bottom surface 221c opposite to each other in the thickness direction TT. Exemplarily, the top surface 221b of the first hinge portion 221 may be flush with the top side 213 , and the bottom surface 221c may be flush with the bottom side 214 .

[0149] like Figure 7B, Fig. 8A and Figure 8B As shown, the first mounting block 230 may include a second hinge portion 231, which is formed with a second hinge hole 231a extending along the width direction WW. Exemplarily, as shown in the figure, the second hinge portion 231 is composed of two hinge legs, each of which is formed with a second hinge hole 231a. It should be understood that the specific type of the second hinge portion 231 is not limited thereto.

[0150] The first hinge hole 221a of the first hinge portion 221 of the beam 210 and the second hinge hole 231a of the second hinge portion 231 of the first mounting block 230 are aligned with each other. Fig.7D and Fig. 7E As shown, the first hinge portion 221 is received between two hinge legs constituting the second hinge portion 231 so that the first hinge hole 221a and the two second hinge holes 231a are aligned with each other. It should be understood that the present application is not limited thereto.

[0151] The mounting mechanism 201 may further include a first pin 250. The first pin 250 may be a quick-release pin (may also be referred to as a quick-release pin or a quick-release pin), and extends through the first hinge hole 221a and the second hinge hole 231a to detachably couple the second hinge portion 231 to the first hinge portion 221. In this manner, the first mounting block 230 is detachably coupled to the first end 211 of the beam 210. The quick-release pin enables the beam 210 to be decoupled from the first mounting block 230 in a non-destructive manner. Exemplarily, the quick-release pin allows the beam 210 to be decoupled from the first mounting block 230 and to be reconnected after being decoupled without using any tools.

[0152] The first mounting block 230 can be moved about the first pin 250 relative to the beam 210 in a first direction 271 (eg, toward the top side 213 of the beam 210) Figure 7F The beam 210 is pivoted in a first direction (schematically indicated by arrows in the figure) and in a second direction opposite to the first direction (ie, a direction away from the top side 213 of the beam 210 and towards the bottom side 214 of the beam, not marked in the figure).

[0153] Figure 7B An exemplary type of the first pin (quick release pin) 250 is schematically shown. Figure 7BAs shown, the first pin 250 includes a pin body 251 having a thinner neck 251a and a wider head 251b, a locking ball 252 (two locking balls in the figure) arranged in the neck 251a and capable of partially extending from the neck 251a and retracting into the neck 251a, a biasing member (not shown) extending in the neck 251a and the head 251b, and an actuating member 253 connected to the biasing member. The actuating member 253 can be actuated to switch the biasing member between a first state and a second state. For example, when the operator presses the actuating member 253, the biasing member is switched from the first state to the second state, and when the operator releases the actuating member 253, the biasing member is switched from the second state to the first state. The biasing member applies a biasing force to the locking ball 252 when in the first state so that it partially extends from the neck 251a, and releases the biasing force to the locking ball 252 when in the second state to allow it to retract into the neck 251a. When the first pin 250 detachably couples the second hinge 231 to the first hinge 221, the neck 251a extends through the first hinge hole 221a and the second hinge hole 231a, the first hinge 221 and the second hinge 231 are held between the locking ball 252 and the head 251b, and the biasing member is in the first state. With the beam 210 supported in this mounting position and the body 11 of the hydrogen storage bottle 10 supported on the second universal ball bearing member 420, the quick release pin having this configuration enables easy operation to disengage the beam 210 from the first mounting block 230. This exemplary type of quick release pin may be referred to as a ball head locking pin. It should be understood that the quick release pin is not limited thereto and may be in any other suitable form.

[0154] like Fig. 8A and Figure 8B As shown, the first mounting block 230 may further include a first support portion 232 extending from the second hinge portion 231 along the length direction LL away from the beam 210. The second hinge portion 231 of the first mounting block 230 may include a first surface 231b. Exemplarily, as shown in the figure, the second hinge portion 231 is composed of two hinged legs, each hinged leg includes a first surface 231b, and the first surfaces 231b of the two hinged legs are coplanar. It should be understood that the specific type of the second hinge portion 231 is not limited thereto. Figure 7G As best shown, the beam 210 is supported by the first mounting block 230 and the second mounting block 240 between the first crossbar 21a and the second crossbar 21b. Figure 6In the case of the installation position shown in FIG. 1 , the first surface 231b of the second hinge portion 231 faces and engages the first end surface 211a of the beam 210 to limit the pivoting of the first mounting block 230 along the first direction 271, and the first support portion 232 is supported on the top side of the first cross bar 21a to limit the pivoting of the first mounting block 230 along the second direction opposite to the first direction 271 (it should be noted that in FIG. Figure 7G In this way, the first mounting block 230 can reliably connect the first end 211 of the beam 210 to the first crossbar 21a.

[0155] like Figure 7G , Figure 7H , Fig. 8A and Figure 8B As shown, the first support portion 232 of the first mounting block 230 includes a first end 232a and a second end 232b opposite to each other in the length direction LL. The second hinged portion 231 (specifically, the two hinged legs of the second hinged portion 231) extends downward from the first end 232a of the first support portion 232 along the thickness direction TT. The first mounting block 230 may also include a first stopper 233, which extends downward from the second end 232b of the first support portion 232 along the thickness direction TT. The second hinged portion 231, the first support portion 232 and the first stopper 233 together form an inverted U-shaped buckle portion for buckling on the first crossbar 21a of the bracket 20. In this way, the reliability of connecting the first end 211 of the beam 210 to the first crossbar 21a can be further improved. When the beam 210 is disconnected from the first mounting block 230, the first mounting block 230 having such an inverted U-shaped buckle portion can be moved upward from the first crossbar 21a.

[0156] like Figure 7H and Figure 8B As best shown, the first support portion 232 further includes a second surface 232c at the first end 232a. The second hinge portion 231 extends downwardly from the second surface 232c of the first support portion 232 along the thickness direction TT. In some embodiments, the beam 210 is supported by the first mounting block 230 and the second mounting block 240 between the first crossbar 21a and the second crossbar 21b. Figure 6 In the case of the installation position shown, the second surface 232c of the first support portion 232 faces and engages the top surface 221b of the first hinge portion 221 to limit the pivoting of the first mounting block 230 along the first direction 271. With this configuration, the contact area between the first mounting block 230 and the beam 210 can be increased when the beam 210 is supported in the installation position, thereby improving the supporting capacity of the support assembly 200.

[0157] like Fig. 7A , Figure 7B , Fig.7D and Fig. 7E As shown, the beam 210 may also have a second end surface 212a at the second end 212, and a third hinge portion 222 extending from the second end surface 212a along the length direction LL. The configuration of the third hinge portion 222 may be similar to that of the first hinge portion 221. The third hinge portion 222 protrudes from the second end surface 212a along the length direction LL. The third hinge portion 222 is formed with a third hinge hole 222a ( Figure 7B ). The third hinge hole 222a extends through the third hinge portion 222 along the width direction WW. The third hinge portion 222 includes a top surface and a bottom surface (not shown) opposite to each other in the thickness direction TT. Similar to the first hinge portion 221, the top surface of the third hinge portion 222 may be flush with the top side 213, and the bottom surface of the third hinge portion 222 may be flush with the bottom side 214.

[0158] like Figure 7B , Figure 8C and Fig.8D As shown, the second mounting block 240 includes a fourth hinge portion 241, and the fourth hinge portion 241 is formed with a fourth hinge hole 241a extending along the width direction WW. Exemplarily, as shown in the figure, the fourth hinge hole 241a is composed of two hinge legs, and each hinge leg is formed with a fourth hinge hole 241a. It should be understood that the specific type of the fourth hinge hole 241a is not limited thereto.

[0159] The third hinge hole 222a of the third hinge portion 222 of the beam 210 and the fourth hinge hole 241a of the fourth hinge portion 241 of the second mounting block 240 are aligned with each other. Fig.7D and Fig. 7E As shown, the third hinge portion 222 is received between two hinge legs constituting the fourth hinge portion 241, so that the third hinge hole 222a and the two fourth hinge holes 241a are aligned with each other. It should be understood that the present application is not limited thereto.

[0160] The mounting mechanism 201 may further include a second pin 260. The second pin 260 extends through the third hinge hole 222a and the fourth hinge hole 241a to couple the fourth hinge portion 241 to the third hinge portion 222. In this manner, the second mounting block 240 is coupled to the second end 212 of the beam 210. The second mounting block 240 can be moved relative to the beam 210 in a third direction 273 (e.g., in the direction of the top side 213 of the beam 210) about the second pin 260. Figure 7F The beam 210 is pivoted in a fourth direction (schematically indicated by arrows in the figure) and in a fourth direction opposite to the third direction (ie, a direction away from the top side 213 of the beam 210 and towards the bottom side 214 of the beam, not marked in the figure).

[0161] In some embodiments, similar to the first pin 250, the second pin 260 can be a quick release pin to detachably couple the fourth hinge 241 to the third hinge 222. In this way, the second mounting block 240 is detachably coupled to the second end 212 of the beam 210. The quick release pin enables the beam 210 to be decoupled from the second mounting block 240 in a non-destructive manner. Exemplarily, the beam 210 can be decoupled from the second mounting block 240 and reconnected after decoupling without using any tools. The second pin 260 can be in the form of the aforementioned ball head locking pin. It should be understood that the second pin 260 is not limited thereto and can be in any other suitable form.

[0162] In some other embodiments, the second pin may couple the second mounting block 240 to the second end 212 of the beam 210 in a non-detachable manner.

[0163] Similar to the first mounting block 230, Figure 8C and Fig.8D As shown, the second mounting block 240 may include a second support portion 242 extending from the fourth hinge portion 241 along the length direction LL away from the beam 210. The fourth hinge portion 241 of the second mounting block 240 includes a third surface 241b. Exemplarily, as shown in the figure, the fourth hinge portion 241 is composed of two hinged legs, each hinged leg includes a third surface 241b, and the third surfaces 241b of the two hinged legs are coplanar. It should be understood that the specific type of the fourth hinge portion 241 is not limited to this. Although not specifically shown in the figure, it is conceivable that, similar to the cooperation between the first mounting block 230 and the first end 211 of the beam 210, the beam 210 is supported by the first mounting block 230 and the second mounting block 240 between the first cross bar 21a and the second cross bar 21b. Figure 6 In the case of the installation position shown in FIG. 1 , the third surface 241b of the fourth hinge portion 241 faces and engages with the second end surface 212a of the beam 210 to limit the pivoting of the second mounting block 40 along the third direction 273, and the second support portion 242 is supported on the top side of the second cross bar 21b to limit the pivoting of the second mounting block 240 along the fourth direction opposite to the third direction 273 (it should be noted that in FIG. Figure 7G In this way, the second mounting block 240 can reliably connect the second end 212 of the beam 210 to the second crossbar 21b.

[0164] like Figure 8C and Fig.8DAs shown, the second support portion 242 of the second mounting block 240 includes a first end 242a and a second end 242b opposite to each other in the length direction LL. The fourth hinge portion 241 (specifically, the two hinged legs of the fourth hinge portion 241) extends downward from the first end 242a of the second support portion 242 along the thickness direction TT. Unlike the first mounting block 230, the second mounting block 240 does not have a limiting portion similar to the first limiting portion 233, but the fourth hinge portion 241 and the second support portion 242 together constitute an inverted L-shaped buckle portion for buckling on the second cross bar 21b. On the one hand, when the beam 210 is supported by the first mounting block 230 and the second mounting block 240, it is located between the first cross bar 21a and the second cross bar 21b. Figure 6 In the case of the installation position shown, the inverted L-shaped buckle configuration of the second mounting block 240 can reliably connect the second end 212 of the beam 210 to the second crossbar 21b. On the other hand, when the beam 210 is disconnected from the first mounting block 230, the inverted L-shaped buckle configuration of the second mounting block 240 can make the second mounting block 240 easily move away from the second crossbar 21b and move downward together with the beam 210 without interfering with other parts such as the bottle body 11 and the crossbar.

[0165] The first mounting block 230 has an inverted U-shaped buckle configuration and is detachably connected to the beam 210, and the second mounting block 240 has an inverted L-shaped buckle configuration, which can facilitate the removal of at least the beam 210 of the support assembly 200 from the beam 210. Figure 6 The installation position shown is moved downward away from the second accommodation space 20b. As described above, this enables the operator to transfer the hydrogen storage bottle 10 to the retaining seat 25 without changing or substantially changing the position and rotational orientation of the hydrogen storage bottle 10 after transferring the hydrogen storage bottle 10 to the second accommodation space 20b of the bracket 20 using the support assembly 200 and adjusting the rotational orientation of the hydrogen storage bottle 10 around the longitudinal center axis 12.

[0166] like Fig.8D As best shown, the second support portion 242 of the second mounting block 240 further includes a fourth surface 242c at the first end 242a. The fourth hinge portion 241 extends downwardly from the fourth surface 242c of the second support portion 242 along the thickness direction TT. In some embodiments, similar to the first mounting block 230, the beam 210 is supported by the first mounting block 230 and the second mounting block 240 between the first crossbar 21a and the second crossbar 21b. Figure 6In the case of the installation position shown, the fourth surface 242c of the second support portion 242 of the second installation block 240 faces and engages with the top surface (not shown) of the fourth hinge portion 241 to limit the pivoting of the second installation block 240 along the third direction 273. With this configuration, the contact area between the second installation block 240 and the beam 210 can be increased when the beam 210 is supported in the installation position, thereby improving the supporting capacity of the support assembly 200.

[0167] The support assembly 200 can assist in transferring the hydrogen storage bottle 10 from the transport vehicle 100 or other mechanism to the corresponding accommodation space of the bracket 20 (eg, Figure 1D ), and adjusting the rotational orientation of the hydrogen storage bottle 10 around the longitudinal center axis 12 after placing the hydrogen storage bottle 10 in the corresponding accommodation space of the bracket 20. In addition, the support assembly 200 can be used to transfer the hydrogen storage bottle 10 to the second accommodation space 20b of the bracket 20 without changing or substantially changing the position and rotational orientation of the hydrogen storage bottle 10, after transferring the hydrogen storage bottle 10 to the second accommodation space 20b of the bracket 20 and adjusting the rotational orientation of the hydrogen storage bottle 10 around the longitudinal center axis 12.

[0168] Although it is described above that the support assembly 200 is detachably mounted on the bracket 20 , it should be understood that in some other embodiments, the support assembly 200 may also be non-detachably mounted on the bracket 20 .

[0169] Positioning components

[0170] The tool kit 1 also includes a positioning assembly 300, which is configured to be mounted on the bracket 20 to position and / or orient the hydrogen storage bottle 10. Specifically, the positioning assembly 300 can be configured to be mounted in the accommodating space of the bracket 20 to help the operator to perform translational positioning and / or rotational orientation of the hydrogen storage bottle 10 when the hydrogen storage bottle 10 is placed in the accommodating space.

[0171] like Figure 1C and Figure 1D As shown, the hydrogen storage bottle 10 is placed in the second accommodating space 20b from one end of the second accommodating space 20b, and the second accommodating space 20b also includes another end opposite to the end in the direction YY along the longitudinal center axis 12. Figure 1A and Figure 1B As best shown, the positioning assembly 300 is mounted to the bracket 20 at the other end of the accommodating space, and is located to assist the operator in translating and / or rotating the hydrogen storage bottle 10 .

[0172] In some embodiments, the positioning assembly 300 may be fixed to the bracket 20. In other embodiments, the positioning assembly 300 may be detachably mounted to the bracket 20 so as to be removed from the bracket 20 and reused after completing the translation positioning and / or rotation orientation.

[0173] The following will further combine Fig. 9 , Fig. 10A and Fig. 10B An exemplary configuration of the positioning assembly 300 is described in detail. Fig. 9 yes Figure 1B , which shows that the positioning assembly 300 is installed in the second accommodating space 20b of the bracket 20, Fig. 10A and Fig. 10B is a perspective view of the positioning assembly 300 .

[0174] like Fig. 9 As shown, the second accommodating space 20 b is located between the second crossbar 21 b and the third crossbar 21 c in the crossbar 21 of the bracket 20 and above the second crossbar 21 b and the third crossbar 21 c.

[0175] The positioning assembly 300 is arranged in the second accommodating space 20b, and may include a mounting mechanism 301, a translation positioning mechanism 302, and a rotation positioning mechanism 303. The mounting mechanism 301 is configured to mount the positioning assembly 300 on the second crossbar 21b and the third crossbar 21c of the bracket 20. Exemplarily, as shown in the figure, the mounting mechanism 301 may be a bridge that is snapped on the second crossbar 21b and the third crossbar 21c. It should be understood that the present application is not limited thereto, and the mounting mechanism 301 may be any suitable mechanism that can be detachably mounted on the bracket 20 and on which the translation positioning mechanism 302 and / or the rotation positioning mechanism 303 can be arranged. For example, the configuration of the mounting mechanism 301 of the positioning assembly 300 may be the same as the configuration of the mounting mechanism 201 of the support assembly 200.

[0176] The translation positioning mechanism 302 may be disposed on the mounting mechanism 301 and is constructed and arranged to define the terminal position of the hydrogen storage bottle 10 in the second accommodation space 20b on the support assembly 200 along the direction YY of the longitudinal center axis 12. Fig. 9 and Fig. 10BAs shown, the translation positioning mechanism 302 can be engaged with the column 22 on one side thereof, and can include a translation positioning portion 302a on the other side thereof. The translation positioning portion 302a can define the end position (or limit position) of the translation stroke of the hydrogen storage bottle 10. Specifically, the translation positioning portion 302a can limit the translation of the hydrogen storage bottle 10 along the direction YY of the longitudinal center axis 12 on the support assembly 200 by engaging with the first end 14a of the bottle body 11 of the hydrogen storage bottle 10 (for example, a portion or component on the first end 14a). Since the translation positioning mechanism 302 is engaged with the column 22, the translation positioning mechanism 302 can reliably limit the translation of the hydrogen storage bottle 10.

[0177] The rotational positioning mechanism 303 may be disposed on the translational positioning mechanism 302. It should be understood that the rotational positioning mechanism 303 is not limited thereto, and in other embodiments, the rotational positioning mechanism 303 housing may be disposed on the mounting mechanism 301. The rotational positioning mechanism 303 includes a first mark, and the hydrogen storage bottle 10 includes a second mark. The rotational positioning mechanism 303 is constructed and arranged so that when the hydrogen storage bottle 10 is supported on the support assembly 200 in the second accommodating space 20b, the rotational orientation of the hydrogen storage bottle 10 around the longitudinal center axis 12 can be determined by observing the position of the first mark relative to the second mark. For example, as Figures 9 to 10B As shown, the first mark of the rotational positioning mechanism 303 can be three positioning holes 303a, and the second mark of the hydrogen storage bottle 10 can be three positioning holes on the first end 14a of the bottle body 11 (not shown, for example, it can be a valve member at the first end 14a). When the hydrogen storage bottle 10 is rotated around the longitudinal center axis 12 on the support assembly 200 so that its three positioning holes are aligned with the three positioning holes 303a of the rotational positioning mechanism 303, the hydrogen storage bottle 10 is in the desired rotational orientation. The first mark and the second mark are not limited to this, and can be any mark that can determine the rotational orientation of the hydrogen storage bottle 10 around the longitudinal center axis 12. For the hydrogen storage bottle 10, the second mark can be the original structure of the hydrogen storage bottle 10 or can be an additional structure or mark.

[0178] It should be understood that the positioning assembly 300 may include at least one of the translation positioning mechanism 302 and the rotation positioning mechanism 303. It should also be understood that the mounting mechanism 301 may be absent, and the translation positioning mechanism 302 and / or the rotation positioning mechanism 303 may be directly mounted to the bracket 20.

[0179] When placing the hydrogen storage bottle 10 in the accommodation space, the operator can use the positioning assembly 300 to efficiently perform translation positioning and / or rotation orientation on the hydrogen storage bottle 10 .

[0180] It should be understood that the present application also proposes a method for operating the hydrogen storage bottle 10. The method may include assembling the hydrogen storage bottle 10 onto the bracket 20 of the hydrogen storage system using a tool kit 1 including a transport vehicle 100, a support assembly 200, and a positioning assembly 300. The assembly process has been specifically described above in conjunction with the structure of these tools, so it will not be repeated here.

[0181] Although the above description is about the assembly process of assembling the hydrogen storage bottle 10 to the bracket 20 of the hydrogen storage system, it should be understood that the tool kit 1 including the transport vehicle 100, the support assembly 200 and the positioning assembly 300 can disassemble and remove the hydrogen storage bottle 10 from the bracket 20 of the hydrogen storage system. The disassembly process can be the opposite of the assembly process described above.

[0182] The tool kit 1 including the transport vehicle 100, the support assembly 200 and the positioning assembly 300 can improve the efficiency and safety of assembling and / or disassembling the hydrogen storage bottle 10 to the bracket 20 without changing the original structure of the bracket 20 of the hydrogen storage system.

[0183] Although the above description is that the transport vehicle 100, the support assembly 200 and the positioning assembly 300 of the tool kit 1 are used in combination, it should be understood that each of the transport vehicle 100, the support assembly 200 and the positioning assembly 300 can be used alone or in any combination to achieve corresponding functions.

[0184] Although the tool kit 1 is described above as being used to operate a hydrogen storage bottle 10, it should be understood that the tool kit 1 can operate any other storage bottle having a substantially cylindrical body. Such a storage bottle can be any solid, liquid and gas storage bottle, such as an oxygen bottle, a nitrogen bottle, etc. In addition, the operating object of the tool kit 1 is not limited to a storage bottle, but can be any bottle tank having a substantially cylindrical body. Exemplarily, a plurality of universal ball bearing members can be provided in any suitable component or position to be constructed and arranged to support the bottle body on the side surface of the bottle body so as to: (i) orient the bottle body in a manner such that the longitudinal central axis is substantially perpendicular to the direction of gravity; (ii) limit the movement of the bottle body in a lateral direction substantially perpendicular to both the direction of gravity and the direction of the longitudinal central axis; and (iii) enable the bottle body to rotate around the longitudinal central axis and translate along the direction of the longitudinal central axis. The structure and arrangement of the plurality of universal ball bearing members are the same as the structure and arrangement of the first universal ball bearing member and the second universal ball bearing member. For example, a plurality of universal ball bearing members may be disposed on or in the frame to constitute a conveying track for conveying storage bottles.

[0185] In the present application, the terms “first”, “second”, “third” and “fourth” are only used to distinguish one element, component or section from another element, component or section, but these elements, components and sections should not be limited by such terms.

[0186] The present application has been described in detail above in conjunction with specific embodiments. Obviously, the above description and the embodiments shown in the accompanying drawings should be understood as exemplary and do not constitute a limitation to the present application. For those skilled in the art, various modifications or changes can be made to the present application without departing from the spirit of the present application, and these modifications or changes do not depart from the scope of the present application.
