DETAILED DESCRIPTION

[0026] In the following, the application will be further described in combination with specific embodiments. It should be noted that, under the premise of no conflict, the embodiments described below or the technical features between them can be combined to form new embodiments.

[0027] In the description of the present application, it should be noted that for the orientation words, such as the terms "center", "transverse", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation and positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the present application.

[0028] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and do not necessarily describe a specific order or sequence.

[0029] The terms "include" and "have" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0030] One preferred embodiment of the present application, as shown in Figures 1 to 7 A mobile air charging device for energy accumulator of die casting machine, including a box 1, a base 2, a locking assembly 3 and a wheel assembly 4. The box 1 and the base 2 can be detachably fixedly connected through the locking assembly 3. The wheel assembly 4 is installed in the base 2, the wheel assembly 4 can drive the base 2 and the box 1 to move, and the wheel assembly 4 can be retracted in the base 2.

[0031] It should be understood that the main function of the energy accumulator air charging device is to charge nitrogen into the energy accumulator to increase its pressure and energy storage capacity. However, there are many types of die casting machines on the market, resulting in many types of energy accumulators, and different types of energy accumulators require different capacity air charging devices for charging, and thus require the provision of many different types of air charging devices, resulting in increased costs. In this case, if the gas tank of the air charging device can be replaced directly, without the need to replace the entire air charging device, the cost will be greatly reduced. However, the existing air charging device is of an integrated design, and the gas tank cannot be detached and replaced.

[0032] Therefore, in the embodiment, the inflator is designed in a split type, and the inflator is divided into a box body 1 and a base 2; the base 2 is used to bear the box body 1, so as to drive the box body 1 to move. The box body 1 and the base 2 can be detachably fixedly connected through a locking assembly 3. Such a design not only can simplify the transportation process of the inflator, but also can realize that one base 2 can adapt to different models of box bodies 1. Meanwhile, the inflator can be made to retract the wheel body 42 into the base 2 when the inflator is filled with nitrogen, so that the state of the inflator filled with nitrogen is more stable.

[0033] In the embodiment, the inflator is designed in a split type, and the inflator is divided into a box body 1 and a base 2; the base 2 is used to bear the box body 1, so as to drive the box body 1 to move. The box body 1 and the base 2 can be detachably fixedly connected through a locking assembly 3. Such a design not only can simplify the transportation process of the inflator, but also can realize that one base 2 can adapt to different models of box bodies 1. Meanwhile, the inflator can be made to retract the wheel body 42 into the base 2 when the inflator is filled with nitrogen, so that the state of the inflator filled with nitrogen is more stable.

[0034] It can be understood that the box body 1 and the base 2 need to be fixedly connected. However, the fixed connection between the box body 1 and the base 2 in the embodiment is not like the traditional welding connection mode, but needs to be detachably fixedly connected between the box body 1 and the base 2. Such a detachable fixed connection mode can make the inflator be divided into two parts when the box body 1 and the base 2 are transported, so as to be more convenient for transportation and can realize that only the box body 1 needs to be replaced when different models of energy storage devices are filled with nitrogen.

[0035] Therefore, in the embodiment, the locking assembly 3 is used to make the box body 1 and the base 2 be detachably fixedly connected. Figure 2 and Figure 3 As shown in FIGS. 1 and 2, the locking assembly 3 includes a locking column 30, a locking part 31 and an unlocking assembly 32.

[0036] It can be understood that the locking column 30 and the locking part 31 can be matched with each other, so as to be clamped and locked. Meanwhile, the locking assembly 3 is used to make the box body 1 and the base 2 be detachably fixedly connected. Therefore, the locking column 30 and the locking part 31 need to be respectively installed on the box body 1 and the base 2, and cannot be uniformly installed on the box body 1 or the base 2.

[0037] Therefore, in the embodiment, the specific position setting mode of the locking column 30 and the locking part 31 has multiple modes, including but not limited to the following two modes.

[0038] Mode one: the locking column 30 is arranged on the box body 1; and the locking part 31 is arranged on the base 2.

[0039] Mode two: the locking column 30 is arranged on the base 2; and the locking part 31 is arranged on the box body 1.

[0040] It should be known that the above two setting modes can meet the needs of the present application, and those skilled in the art can select according to actual needs; in the embodiment, the second mode is preferred.

[0041] It can be understood that the first mode and the second mode are essentially the same. However, if the locking column 30 is arranged on the box body 1, the locking part 31 is arranged on the base 2, and the unlocking assembly 32 is arranged on the base 2 to unlock the locking part 31, which is not convenient for moving the box body 1 after unlocking.

[0042] Therefore, in the embodiment, as shown in Figure 4 , the locking column 30 is installed on the top of the base 2, the locking part 31 and the unlocking assembly 32 are installed in the box body 1, and when the box body 1 is placed on the top of the base 2, the locking part 31 can be clamped and connected with the locking column 30 under the action of gravity. At the same time, the unlocking assembly 32 can release the clamping and locking of the locking part 31 and the locking column 30.

[0043] In the embodiment, as shown in Figure 2 and Figure 3 , the locking column 30 is provided with a locking slot 300, and the locking part 31 includes at least one locking tongue 310 and an elastic member 311. The locking tongue 310 is slidably installed on the bottom of the box body 1 through the elastic member 311. The locking column 30 can abut against the locking tongue 310 under the action of gravity, so that the locking tongue 310 is retracted until the locking slot 300 corresponds to the position of the locking tongue 310, and the locking tongue 310 rebounds under the action of the elastic force of the elastic member 311 and is clamped and locked with the locking slot 300. The unlocking assembly 32 can drive the locking tongue 310 to displace relative to the direction of the locking slot 300 and release the clamping and locking.

[0044] It can be understood that the bottom of the box body 1 is provided with a mounting hole 10, the locking tongue 310 is installed on the bottom of the box body 1 through the elastic member 311, and part of the end of the locking tongue 310 extends into the mounting hole 10. When the box body 1 is installed on the base 2, the locking column 30 is sleeved in the mounting hole 10. Therefore, the side of the locking column 30 abuts against the extended end of the locking tongue 310, so that the locking tongue 310 is retracted into the box body 1, and the end thereof no longer extends into the mounting hole 10. When the locking slot 300 corresponds to the position of the locking tongue 310, the locking tongue 310 rebounds under the action of the elastic force of the elastic member 311, the end of the locking tongue 310 extends into the locking slot 300, and the locking tongue 310 is clamped and locked with the locking slot 300. At the same time, the unlocking assembly 32 can drive the locking tongue 310 to displace relative to the direction of the locking slot 300 to release the clamping and locking between the locking tongue 310 and the locking slot 300.

[0045] It can also be understood that, as can be seen from the above, the unlocking assembly 32 can drive the direction of the locking tongue 310 to displace relative to the locking slot 300 to release the engagement between the locking tongue 310 and the locking slot 300. Therefore, in the embodiment, as shown in Figure 2 and Figure 3 the unlocking assembly 32 includes an unlocking rod and a rotating piece 320, and the top of the rotating piece 320 is provided with a driving rod 3201. The unlocking rod can drive the rotating piece 320 to rotate, so that the driving rod 3201 abuts against the tail end of the locking tongue 310 and drives the locking tongue 310 to displace.

[0046] It should be understood that, as can be seen from the above, the unlocking rod can drive the rotating piece 320 to rotate. However, there are many ways for the unlocking rod to drive the rotating piece 320 to rotate. In the embodiment, the unlocking rod is provided as a rack 321, and a gear 3202 is provided on the outer side of the rotating piece 320 in the circumferential direction. The rack 321 and the gear 3202 are in gear engagement, and the rack 321 is provided with a holding piece 3210 at one end close to the outer side of the box body 1, and the holding piece 3210 partially extends to the outside of the box body 1 to facilitate the pressing of the staff. By pressing the holding piece 3210, the rack 321 is displaced, and in turn the rotating piece 320 is driven to rotate by the gear 3202. At the same time, the end of the rack 321 away from the holding piece 3210 is elastically connected to the box body 1 by the elastic member 311, so as to facilitate the staff to rebound to the original position after pressing the rack 321 to unlock.

[0047] It should also be understood that, in the embodiment, the locking assembly 3 has two, and the installation positions of the two locking assemblies 3 are located on opposite sides of the box body 1.

[0048] In the embodiment, the reason why the wheel body assembly 4 is provided as retractable into the base 2 is that the existing inflatable device is four-wheel landing when filling nitrogen, but the four-wheel landing setting only facilitates the displacement of the inflatable device in normal times, and the vibration degree generated when filling nitrogen will cause the four-wheel landing setting to cause instability of the inflatable device as a whole.

[0049] It can be understood that the wheel body assembly 4 is provided as retractable. When the inflatable device needs to be displaced, the wheel body assembly 4 can drive the wheel body 42 to the outside of the base 2 to facilitate the displacement of the inflatable device. When the inflatable device is filled with nitrogen, the wheel body 42 is retracted into the base 2 by the wheel body assembly 4, so that the bottom of the base 2 contacts the ground, increases the contact area with the ground, and makes the inflatable device more stable as a whole when filling nitrogen.

[0050] Therefore, in the embodiment, as shown in Figure 5As shown, the wheel body assembly 4 comprises a linkage assembly 41, a wheel body 42 and a driving member 40. One end of the linkage assembly 41 and the driving end of the driving member 40 are hingedly connected. The wheel body 42 and the linkage assembly 41 are rollingly mounted, and the wheel body 42 extends outside the base 2 through the extension opening 20. The driving member 40 can drive the linkage assembly 41 to retract the wheel body 42 into the base 2.

[0051] Specifically, as shown, Figures 5 to 7 the linkage assembly 41 comprises a first linkage 410, a second linkage 411 and a third linkage 412. Both ends of the second linkage 411 are hingedly connected to the first linkage 410 and the third linkage 412, and the second linkage 411 is in a triangular shape. The first linkage 410 and the third linkage 412 are hingedly connected to the base 2 and the driving end of the driving member 40 at the end away from the second linkage 411. The wheel body 42 is mounted at the hinged connection between the first linkage 410 and the second linkage 411. The driving member 40 can drive the third linkage 412 to displace and rotate around the hinged connection with the driving member 40 by driving the air rod 400 to horizontally displace, so that the second linkage 411 and the first linkage 410 rotate, thereby driving the wheel body 42 to retract into the base 2.

[0052] It can be understood that, as shown, Figure 6 the first linkage 410 and the second linkage 411 and the third linkage 412 are hingedly connected, and the first linkage 410 is hingedly connected to the base 2 at the end away from the second linkage 411, thereby forming a first intersection point and a second intersection point between the first linkage 410 and the base 2 and the hinged connection of the second linkage 411, and forming a third intersection point between the hinged connection of the second linkage 411 and the third linkage 412, and forming a force triangle between the first intersection point, the second intersection point and the third intersection point. As known, the triangle has stability, so that the wheel body assembly 4 is stable enough to stably support the base 2 and the box 1. At the same time, the base 2 is provided with a blocking member 21, which can block the third linkage 412 when the force triangle is formed between the first intersection point, the second intersection point and the third intersection point, so as to prevent the third linkage 412 from rotating around the connection with the air rod 400 towards the driving member 40, thereby providing more stable support.

[0053] It can also be understood that the wheel body assembly 4 is provided in plurality, and is oppositely mounted along the diagonal of the base 2.

[0054] The foregoing describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments, and the above-described embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
