Description

Technical Field

[0001] The present invention relates to a charging rack and an energy cabinet having the charging rack, and in particular to a charging rack with a pop-up mechanism and an energy cabinet having the charging rack. Background Art

[0002] With the rapid development of electric vehicles, battery energy cabinets have gradually become popular as the main charging facilities. Since energy cabinets are important public systems for providing battery charging and involve functions that require long-term battery charging and operation, they must have more stringent security measures. Among them, battery energy cabinets are equipped with many charging racks as areas for placing batteries when they are drawn out for charging.

[0003] See also Figures 1 to 4 For example, Taiwan Patent No. M609675 and No. M609676 disclose an energy cabinet 1 (such as Figure 4 ) and a plurality of charging racks 120 each having a pop-up mechanism 123. Each pop-up mechanism 123 is disposed in a corresponding charging rack 120 and is provided with a plurality of elastic elements 1234 and a plurality of ejection components 1232.

[0004] When no battery is placed in the internal space of the charging rack 120 for charging, the ejection member 1232 is not pressed by the battery, so the elastic element 1234 is in a state of Figure 1 , 2 The uncompressed state is shown. Then, Figure 3 As shown, when the battery 130 is inserted into the charging rack 120 and combined with a connecting terminal 122, the elastic element 1234 is compressed to store energy, wherein the energy can be transmitted to the ejection component 1232, so that the ejection component 1232 applies a thrust to the battery 130. Moreover, while the insertion action of the battery 130 causes the elastic element 1234 to be compressed, a connected portion (not shown) of the battery 130 can cause a locking device 1235 to be engaged and connected to the connected portion, so that the battery 130 can be charged in a locked state, that is, as shown in FIG. Figure 3 Then, when the battery 130 is fully charged and the energy cabinet 1 determines to provide the battery 130 to the user, the locking device 1235 is unlocked and no longer engages the connected portion of the battery 130, so that the ejection component 1232 ejects the battery 130 due to the elastic force of the elastic element 1234, allowing the user to access the battery 130.

[0005] However, if Figure 1 , 4As shown, during the operation of the conventional energy cabinet 1, since the ejection stroke of each ejection component 1232 is only based on the elastic force of the corresponding single-section elastic element 1234, the ejection stroke is relatively short (approximately only 13.7 mm), resulting in Figure 4 As shown, only a small part of the battery 130 that is pushed out protrudes beyond the front surface of the energy cabinet 1, making it difficult for the user to quickly observe that the battery 130 has been pushed out, or even if the user has discovered that the battery 130 has been pushed out, it is difficult to remove the battery 130.

[0006] Furthermore, when the user pushes the battery 130 to be charged into the charging rack 120 for charging, if the battery 130 is not pushed all the way in at once, the battery 130 will be pushed back due to the elastic force of the elastic element 1234. However, since the push-back distance of the battery 130 is short, it is difficult for the user to detect that the battery 130 has been pushed back, and the user mistakenly believes that the battery 130 is already being charged, resulting in failure to successfully replace the battery. Summary of the invention

The front ejection mechanism of the pop-up mechanism can be pushed by the battery to compress the first spring until the front end surface of the front ejection mechanism is flush with the front end surface of the rear ejection mechanism, and then the battery continues to push the front ejection mechanism and the rear ejection mechanism, so that the front ejection mechanism continues to compress the first spring, and at the same time, the stopper of the rear ejection mechanism compresses the second spring until the front end surface of the rear ejection mechanism and the front end surface of the front ejection mechanism are both flush with the front limit plate of the frame.

[0011] In some embodiments of the present invention, the elastic coefficient of the second spring is greater than the elastic coefficient of the first spring.

[0012] In some embodiments of the present invention, the elastic coefficient of the second spring is equal to the elastic coefficient of the first spring.

[0016] In some embodiments of the present invention, the frame further includes a rear cover disposed behind the rear limiting plate, and the rear cover can isolate the closed end of the rear ejection mechanism from the wires to prevent the wires from being drawn in when the closed end is displaced.

[0017] In some embodiments of the present invention, the charging rack further includes a connecting terminal arranged on the front limit plate of the rack body, wherein the battery can enter the battery accommodating space through the battery entrance of the battery accommodating space to be detachably electrically connected to the connecting terminal.

[0018] In some embodiments of the present invention, the charging rack further includes a locking device arranged on the rack and located below the connecting terminal, wherein a connected portion is provided on the lower surface of the battery, and when the front end surface of the rear ejection mechanism and the front end surface of the front ejection mechanism are both flush with the front limit plate of the rack, the locking device is snapped together and connected to the connected portion, and the battery is electrically connected to the connecting terminal, so that the battery can be charged, and then when the battery is fully charged and the locking device unlocks the connected portion, the locking device no longer snaps together and connects to the connected portion, so that the pop-up mechanism ejects the battery due to the elastic force of the first spring and the second spring.

[0019] In some embodiments of the present invention, the energy cabinet includes a cabinet body; and a plurality of charging racks as described in the aforementioned embodiments, wherein each charging rack is disposed in the battery cabinet body, and the battery entrance of the battery accommodating space of each charging rack is connected to the battery accommodating space and the outside of the cabinet body, so that the battery can enter the battery accommodating space from the outside of the cabinet body through the battery entrance.

[0020] [Effects of the Invention]

[0021] The effects of the present invention are as follows: (a) the front ejection mechanism can extend the length of the ejection stroke, making it easier for the user to remove the battery from the charging stand. However, the telescopic design of the front ejection mechanism elastically sliding in the cavity of the rear ejection mechanism can effectively save the total length requirement of the front ejection mechanism and the rear ejection mechanism; (b) even if the battery is not pushed all the way in at once, the battery will be obviously pushed back by the front ejection mechanism and the rear ejection mechanism, making it easy for the user to visually determine whether the battery is locked; (c) in the case where the elastic coefficient of the first spring is less than the elastic coefficient of the second spring (d) the flange at the closed end of the rear ejection mechanism can make the process of assembling and positioning the rear ejection mechanism, the front ejection mechanism, the first spring and the second spring on the front limit plate and the rear limit plate faster and more convenient; (e) the rear cover can isolate the closed end of the rear ejection mechanism from the wires to prevent the wires from being drawn in when the closed end is displaced.

[0074] See also Figures 5 to 8The embodiment of the energy cabinet with a charging rack of the present invention comprises a cabinet body 7 and a plurality of charging racks 8. In this embodiment, each charging rack 8 is disposed in the battery cabinet body 7 and is suitable for accommodating a battery 9.

[0075] like Figure 5 , 6 , 7, in this embodiment, each charging rack 8 includes a rack body 80, a connection terminal 81, a pop-up mechanism 82, and a locking device 83. The rack body 80 defines a battery accommodating space 800 extending along a front-to-back direction and provided with a battery entrance 8000, and includes a front stop plate 801 located at the rear of the battery accommodating space 800 and provided with a front through hole 8010, a rear stop plate 802 located at the rear of the front stop plate 801 and provided with a rear through hole 8020, and a rear cover 803 disposed at the rear of the rear stop plate 802.

[0076] In this embodiment, the battery entrance 8000 of the battery accommodating space 800 of each charging rack 8 is connected to the inside of the battery accommodating space 800 and the outside of the cabinet 7, so that the battery 9 can enter the battery accommodating space 800 from the outside of the cabinet 7 through the battery entrance 8000.

[0077] In this embodiment, the connection terminal 81 is disposed on the front limiting plate 801 , wherein the battery 9 can enter the battery accommodating space 800 through the battery inlet 8000 to be detachably electrically connected to the connection terminal 81 .

[0078] In this embodiment, the ejection mechanism 82 is disposed on the frame 80 and includes at least one rear ejection mechanism 821, at least one front ejection mechanism 822, at least one first spring 823, and at least one second spring 824. Figure 6 , 7 The four rear ejection mechanisms 821 , the four front ejection mechanisms 822 , the four first springs 823 , and the four second springs 824 are shown.

[0079] like Figure 6 , 7As shown in Figure 8, in the present embodiment, the rear ejection mechanism 821 extends along the front-to-back direction and passes through the front through hole 8010 of the front limit plate 801 and the rear through hole 8020 of the rear limit plate 802, and has a tube body 8210 between the front limit plate 801 and the rear limit plate 802, an open end 8211 extending forward from the tube body 8210 and passing through the front through hole 8010, a closed end 8212 extending backward from the tube body 8210 and passing through the rear through hole 8020, and a stopper 8213 (such as a flange, etc.) extending radially outward from the outer wall of the front end of the tube body 8210, and a cavity 8214 extending forward from the closed end 8212 to the front outlet of the open end 8211 is provided. In this embodiment, the cavity 8214 has a large diameter section 8215 extending forward from the closed end 8212 , and a small diameter section 8216 extending from the large diameter section 8215 to the front exit of the open end 8211 .

[0080] In this embodiment, the rear cover 803 can isolate the closed end 8212 of the rear ejection mechanism 821 from the wire (not shown) to prevent the wire from being drawn in when the closed end 8212 is displaced.

[0081] In this embodiment, the front ejection mechanism 822 has a large diameter portion 8221 confined within the large diameter section 8215 of the cavity 8214 of the rear ejection mechanism 821, and a small diameter portion 8222 extending forward from the large diameter portion 8221 through the small diameter section 8216 of the cavity 8214 and protruding out of the rear ejection mechanism 821.

[0082] In this embodiment, the tube body 8210 of the rear ejection mechanism 821 is a round tube, and the large diameter portion 8221 and the small diameter portion 8222 of the front ejection mechanism 822 are both round rods.

[0083] In this embodiment, the first spring 823 is disposed in the cavity 8214 of the rear ejection mechanism 821 , and abuts between the closed end 8212 of the rear ejection mechanism 821 and the large diameter portion 8221 of the front ejection mechanism 822 .

[0084] In this embodiment, the second spring 824 is sleeved on the outer wall of the tube body 8210 of the rear ejection mechanism 821 , and is limited between the stopper 8213 of the rear ejection mechanism 821 and the rear limiting plate 802 .

[0085] In addition, in the present embodiment, the closed end 8212 of the rear ejection mechanism 821 is provided with a flange 8217 having a diameter larger than the diameter of the rear through hole 8020 of the rear limiting plate 802, so as to facilitate the installation process of the charging rack 8 of the present invention, especially in the manufacturing and assembly process of the charging rack 8 of the present invention, the front ejection mechanism 822 and the first spring 823 are first sequentially installed into the cavity 8214, and the second spring 824 is sleeved on the outer surface of the tube body 8210 of the rear ejection mechanism 821. The rear ejection mechanism 821 is mounted on the wall, and a screw provided with the flange 8217 is used to lock into the cavity 8214 from the rear end of the rear ejection mechanism 821 to form the closed end 8212, wherein, since the closed end 8212 of the rear ejection mechanism 821 is provided with the flange 8217, the process of installing and positioning the rear ejection mechanism 821, the front ejection mechanism 822, the first spring 823 and the second spring 824 on the front limit plate 801 and the rear limit plate 802 can be faster and more convenient.

[0086] See also Figure 6 , 9 , 12. In this embodiment, a connected portion 91 is provided on the lower surface of the battery 9. The locking device 83 is arranged on the front limit plate 801 of the frame 80 and is located below the connecting terminal 81. The locking device 83 is provided with a bottom plate 830, a first swing arm 831, a second swing arm 832, a solenoid valve 835, a micro switch 836, and a tension spring 837 and other components. A buckling section 833 is provided through the bottom plate 830. The first swing arm 831 is pivotally connected to the bottom plate 830. The second swing arm 832 is also pivotally connected to the bottom plate 830, and can be engaged with or separated from the first swing arm 831. In addition, the second swing arm 832 is provided with a buckling groove 834. The buckling groove 834 is laterally recessed on one side of the second swing arm 832 adjacent to the first swing arm 831, so that when the second swing arm 832 is engaged with the first swing arm 831, the buckling section 833 and the buckling groove 834 together form a closed buckling groove, so as to be able to buckle and connect and lock the connected portion 91 of the battery 9. Fig.12 shown.

[0087] See also Figure 5 , 8 , 9, 10, when the battery 9 of an electric vehicle (not shown) is too low in power and needs to be replaced, the user can insert the battery 9 into one of the empty charging racks 8 of the cabinet body 7 of the energy cabinet, for example, Figure 5The cabinet 7 has accommodated four batteries 9, and the topmost grid shows a front cover 71, indicating that the charging rack 8 therein does not accommodate any batteries. Therefore, the user can use the battery 9 with low power to rotate the front cover 71 inward and backward to push it in, so that the battery 9 can push the front ejection mechanism 822 of the charging rack 8 and compress the first spring 823 until the front end surface of the front ejection mechanism 822 is flush with the front end surface of the rear ejection mechanism 821, as shown in FIG. Fig.10 shown.

[0088] See also Figure 5 , 11 , 12, then, the battery 9 continues to push the front ejection mechanism 822 and the rear ejection mechanism 821, so that the front ejection mechanism 822 continues to compress the first spring 823, and at the same time the stopper 8213 of the rear ejection mechanism 821 compresses the second spring 824, until the front end surface of the rear ejection mechanism 821 and the front end surface of the front ejection mechanism 822 are both flush with the front limit plate 801, as shown in FIG. Fig.11 shown.

[0089] At this time, the battery 9 is electrically connected to the connection terminal 81, and Fig.12 As shown, due to the coordinated operation of the tension spring 837, the solenoid valve 835 and the micro switch 836, the connected portion 91 of the battery 9 can be limited to the closed buckle groove formed by the buckle section 833 and the buckle groove 834, and the appearance is as shown in FIG. Fig.12 Therefore, in the locked state where the battery 9 is electrically connected to the connection terminal 81, the energy cabinet can charge the battery 9 to be charged, read the user data in the battery 9, and then store the user data in another fully charged battery 9 in the cabinet 7.

[0090] Then, since the fully charged battery 9 has stored the user data, the locking device 83 can unlock the connected portion 91 of the battery 9 through the coordinated operation of the tension spring 837, the solenoid valve 835, and the micro switch 836 of the locking device 83 of the charging stand 8 that accommodates the fully charged battery 9, so that the locking device 83 is no longer engaged with the connected portion 91, and the ejection mechanism 82 ejects the battery 9 for the user to use due to the elastic force of the first spring 823 and the second spring 824. In addition, it should be noted that the details of the coordinated operation of the tension spring 837, the solenoid valve 835, and the micro switch 836 of the locking device 83 have been disclosed in the aforementioned Taiwan Patent Nos. M609675 and M609676, and are not the focus of the present invention, so it is understood that it is not necessary to repeat them in the present invention specification.

[0091] Furthermore, in this embodiment, the elastic coefficient of the second spring 824 is greater than the elastic coefficient of the first spring 823, so that when the elastic coefficient of the first spring 823 is small, the first spring 823 is easier to be compressed, which can significantly improve the push-in feel of the battery 9, thereby increasing the acceleration distance, and the instantaneous force applied when the second spring 824 with a larger elastic coefficient is pushed is assisted, making it easier for the user to apply force. However, the present invention is not limited to the elastic coefficient of the second spring 824 being greater than the elastic coefficient of the first spring 823, but in other embodiments, the elastic coefficient of the second spring 824 can also be less than or equal to the elastic coefficient of the first spring 823.

[0092] In summary, the present invention has at least the following advantages and effects: (a) the front ejection mechanism 822 can extend the length of the ejection stroke, making it easier for the user to remove the battery 9 from the charging stand 8. However, the telescopic design of the front ejection mechanism 822 being able to elastically slide in the cavity 8214 of the rear ejection mechanism 821 can effectively save the total length requirement of the front ejection mechanism 822 and the rear ejection mechanism 821; (b) even if the battery 9 is not pushed in to the bottom at once, the battery 9 will be obviously pushed back by the front ejection mechanism 822 and the rear ejection mechanism 821, making it easy for the user to visually determine whether the battery 9 is locked; (c) when the elastic coefficient of the first spring 823 is less than the elastic coefficient of the second spring 824, the first spring 823 is The spring 823 is easier to be compressed, which can significantly improve the push-in feel of the battery 9, thereby increasing the acceleration distance, so that the instantaneous force applied by the second spring 824 with a larger elastic coefficient when being pushed is assisted, making it easier for the user to apply force; (d) the flange 8217 of the closed end 8212 of the rear ejection mechanism 821 can make the process of installing and positioning the rear ejection mechanism 821, the front ejection mechanism 822, the first spring 823 and the second spring 824 on the front limit plate 801 and the rear limit plate 802 faster and more convenient; (e) the rear cover 803 can isolate the closed end 8212 of the rear ejection mechanism 821 from the wires to avoid the closed end 8212 from being drawn into the wires when the closed end 8212 is displaced; therefore, the purpose of the present invention can be achieved.

[0093] The above descriptions are merely embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the claims and description of the present invention are still within the scope of the present invention.
