In this embodiment, the first mounting platform 110 and the second mounting platform 120 of the battery holder 100 may be formed with a plurality of coupling holes H, and these coupling holes H are all located on the same side of the battery holder 100.

請參閱第4A、4B圖，前述電池模組200主要包括一本體210、一電性連接部220、以及一抵接部240。前述本體210具有一第一表面211、一第二表面212、一第三表面213、一第四表面214、以及一頂面215，其中第一表面211相反於第二表面212，第三表面213相反於第四表面214。第三表面213和第四表面214連接第一表面211和第二表面212，且頂面連接前述第一、第二、第三、第四表面211、212、213、214。電性連接部220設置於第四表面214上，且抵接部240形成於頂面215上。Please refer to FIGS. 4A and 4B. The aforementioned battery module 200 mainly includes a main body 210, an electrical connection portion 220, and an abutting portion 240. The aforementioned body 210 has a first surface 211, a second surface 212, a third surface 213, a fourth surface 214, and a top surface 215, wherein the first surface 211 is opposite to the second surface 212, and the third surface 213 Contrary to the fourth surface 214. The third surface 213 and the fourth surface 214 connect the first surface 211 and the second surface 212, and the top surface connects the aforementioned first, second, third, and fourth surfaces 211, 212, 213, and 214. The electrical connection portion 220 is disposed on the fourth surface 214, and the contact portion 240 is formed on the top surface 215.

如第4C圖所示，第一表面211上形成有一第一導槽250，且第一導槽250具有一圓弧段251和一線狀段252。線狀段252的一端連接圓弧段251，另一端則連接第四表面214。應注意的是，線狀段252並非由圓弧段251的切線方向延伸，因此圓弧段251和線狀段252之間可形成一鈍角或銳角。於本實施例中，圓弧段251和線狀段252具有大致相同的寬度，且圓弧段251和線狀段252的寬度大致相等於第一導引柱131的直徑。As shown in FIG. 4C, a first guide groove 250 is formed on the first surface 211, and the first guide groove 250 has an arc segment 251 and a linear segment 252. One end of the linear segment 252 is connected to the arc segment 251, and the other end is connected to the fourth surface 214. It should be noted that the linear segment 252 does not extend in the tangential direction of the circular arc segment 251, so an obtuse or acute angle may be formed between the circular arc segment 251 and the linear segment 252. In this embodiment, the arc segment 251 and the linear segment 252 have approximately the same width, and the width of the arc segment 251 and the linear segment 252 are approximately equal to the diameter of the first guiding pillar 131.

如第4D圖所示，第二表面212上亦形成有一第二導槽260，且第二導槽260同樣具有一圓弧段261和一線狀段262。線狀段262的一端連接圓弧段261，另一端則連接第四表面214。由於線狀段262並非由圓弧段261的切線方向延伸，故圓弧段261和線狀段262之間可形成一鈍角或銳角。於本實施例中，圓弧段261和線狀段262具有大致相同的寬度，且圓弧段261和線狀段262的寬度大致相等於第二導引柱141的直徑。As shown in FIG. 4D, a second guide groove 260 is also formed on the second surface 212, and the second guide groove 260 also has an arc segment 261 and a linear segment 262. One end of the linear segment 262 is connected to the arc segment 261, and the other end is connected to the fourth surface 214. Since the linear segment 262 does not extend from the tangential direction of the circular arc segment 261, an obtuse or acute angle may be formed between the circular arc segment 261 and the linear segment 262. In this embodiment, the arc segment 261 and the linear segment 262 have approximately the same width, and the width of the arc segment 261 and the linear segment 262 is approximately equal to the diameter of the second guiding pillar 141.

第4E、4F圖係分別表示第4A圖中沿A-A、B-B方向的剖視圖。如圖所示，電池模組200的第三表面213上形成有ㄧ凹孔216，且電池模組200可更包括一滑動件270、一活動件280、以及彈性構件290、291。滑動件270和活動件280以可移動的方式連接本體210，其中滑動件270可相對於本體210沿一第一方向移動，而活動件280則可相對於本體210沿一第二方向移動。於本實施例中，第一方向大致垂直於第二方向。滑動件270的至少一部分會凸出於本體210的第三表面213，且凸出的部分具有一斜面271。彈性構件290、291則例如可為壓縮彈簧，其中彈性構件290連接本體210和活動件280，而彈性構件291則連接本體210和滑動件270。Figures 4E and 4F respectively show cross-sectional views along the A-A and B-B directions in Figure 4A. As shown in the figure, a concave hole 216 is formed on the third surface 213 of the battery module 200, and the battery module 200 may further include a sliding member 270, a movable member 280, and elastic members 290, 291. The sliding element 270 and the movable element 280 are connected to the main body 210 in a movable manner. The sliding element 270 can move in a first direction relative to the main body 210 and the movable element 280 can move in a second direction relative to the main body 210. In this embodiment, the first direction is substantially perpendicular to the second direction. At least a part of the sliding member 270 protrudes from the third surface 213 of the main body 210, and the protruding part has an inclined surface 271. The elastic members 290 and 291 may be compression springs, for example, wherein the elastic member 290 connects the body 210 and the movable part 280, and the elastic member 291 connects the body 210 and the sliding part 270.

以下說明供電裝置P的安裝方式和使用方法。請參閱第5A圖，首先，使用者可將電池固定座100從殼體10上的一開口11放入電動自行車B的殼體10中，鎖固元件300(例如可為螺絲或鉚釘)可穿過殼體10上的穿孔12且與第一安裝台110和第二安裝台120上的結合孔H結合，以將電池固定座100固定於殼體10中。其中，電池固定座100之插座122的位置和驅動部153的位置可分別對應殼體10上之開孔13、14的位置，使插座122和驅動部153可分別由開孔13、14暴露。The installation method and usage method of the power supply device P are described below. Please refer to Figure 5A. First, the user can put the battery holder 100 into the housing 10 of the electric bicycle B from an opening 11 on the housing 10. The locking element 300 (for example, a screw or rivet) can be worn Pass through the perforation 12 on the casing 10 and combine with the coupling holes H on the first installation stand 110 and the second installation stand 120 to fix the battery fixing base 100 in the casing 10. Wherein, the position of the socket 122 and the position of the driving part 153 of the battery holder 100 can correspond to the positions of the openings 13 and 14 on the casing 10 respectively, so that the socket 122 and the driving part 153 can be exposed by the openings 13 and 14 respectively.

需特別說明的是，於本實施例中，殼體10上之開口11和穿孔12會形成於殼體10的同一側，且相反於殼體10的一騎乘表面15(使用者騎乘於電動自行車B上時，此騎乘表面15朝向使用者)。如此一來，前述騎乘表面15可保持完整而不做額外的加工，以便使用者的乘坐。It should be noted that, in this embodiment, the opening 11 and the perforation 12 on the housing 10 are formed on the same side of the housing 10, and opposite to a riding surface 15 of the housing 10 (the user rides on the electric When the bicycle B is on, the riding surface 15 faces the user). In this way, the aforementioned riding surface 15 can be kept intact without additional processing to facilitate the ride of the user.

接著，使用者可使電池模組200與電池固定座100結合。具體而言，請參閱第5B、5C圖，電池固定座100的第一導引柱131和第二導引柱141可分別由線狀段252、262進入第一導槽250和第二導槽260中，並沿著第一導槽250和第二導槽260滑動至一第一位置。由於本實施例中的第一導槽250和第二導槽260彼此對稱，因此以下僅以第一導槽250和第一導引柱131作為示例。Then, the user can combine the battery module 200 with the battery holder 100. Specifically, referring to FIGS. 5B and 5C, the first guide post 131 and the second guide post 141 of the battery holder 100 can enter the first guide groove 250 and the second guide groove through the linear segments 252 and 262, respectively. 260, and slide along the first guide groove 250 and the second guide groove 260 to a first position. Since the first guide groove 250 and the second guide groove 260 are symmetrical to each other in this embodiment, only the first guide groove 250 and the first guide post 131 are taken as examples below.

如第5B~5F圖所示，當第一導引柱131沿著第一導槽250滑動時，電池模組200可相對於電池固定座100沿順時針方向旋轉。當滑動件270接觸固定機構150的插銷151時(第5B圖)，由於插銷151具有朝向開口11的斜面151a，因此可被推動而朝向第一安裝台110移動，進而電池模組200可繼續相對於電池固定座100沿順時針方向旋轉。As shown in FIGS. 5B to 5F, when the first guide post 131 slides along the first guide groove 250, the battery module 200 can rotate in a clockwise direction with respect to the battery holder 100. When the slider 270 contacts the pin 151 of the fixing mechanism 150 (Figure 5B), the pin 151 has a slope 151a facing the opening 11, so it can be pushed and moved toward the first mounting table 110, and the battery module 200 can continue to face each other The battery holder 100 rotates clockwise.

如第5C圖所示，當電池模組200繼續相對於電池固定座100沿順時針方向旋轉，且滑動件270接觸第一安裝台110的凸出部113時，因為滑動件270具有斜面271，因此會被凸出部113推動而相對於本體210朝向遠離第一安裝台110的方向移動。藉此，電池模組200可繼續相對於電池固定座100旋轉。如第5D圖所示，在電池模組200相對於電池固定座100旋轉的過程中，電池模組200的活動件280會接觸第二安裝台120的凸出部114，活動件280將可被凸出部114推動而相對於電池固定座100移動，彈性構件290可因此被壓縮。As shown in Figure 5C, when the battery module 200 continues to rotate clockwise relative to the battery holder 100 and the sliding member 270 contacts the protrusion 113 of the first mounting table 110, because the sliding member 270 has an inclined surface 271, Therefore, it is pushed by the protrusion 113 to move in a direction away from the first mounting platform 110 relative to the main body 210. Thereby, the battery module 200 can continue to rotate relative to the battery holder 100. As shown in Figure 5D, when the battery module 200 rotates relative to the battery holder 100, the movable part 280 of the battery module 200 will contact the protrusion 114 of the second mounting table 120, and the movable part 280 will be able to be The protrusion 114 is pushed to move relative to the battery holder 100, and the elastic member 290 can be compressed accordingly.

如第5E、5F圖所示，當第一導引柱131滑動至第一位置時，電池模組200的電性連接部220會接觸電池固定座100的連接端子121，且固定機構150的插銷151會受到彈性元件152的推力作用而回復到其鎖合位置、進入電池模組200的凹孔216中。As shown in Figures 5E and 5F, when the first guide post 131 slides to the first position, the electrical connection portion 220 of the battery module 200 will contact the connection terminal 121 of the battery holder 100, and the latch of the fixing mechanism 150 The 151 will be pushed by the elastic element 152 to return to its locked position and enter the recess 216 of the battery module 200.

通過前述步驟，供電裝置P可被設置於電動自行車B的殼體10中，其中電池固定座100被固定於殼體10上，且電池模組200以可拆卸的方式可固定於電池固定座100上。電池固定座100的連接端子121可與電動自行車B的驅動馬達20電性連接，使電池模組200可經由電性連接部220和連接端子121將電力供給至驅動馬達20。Through the foregoing steps, the power supply device P can be installed in the housing 10 of the electric bicycle B, wherein the battery holder 100 is fixed to the housing 10, and the battery module 200 can be fixed to the battery holder 100 in a detachable manner on. The connection terminal 121 of the battery holder 100 can be electrically connected to the drive motor 20 of the electric bicycle B, so that the battery module 200 can supply power to the drive motor 20 via the electrical connection portion 220 and the connection terminal 121.

當電池模組200的電力耗盡時，使用者可將外部電源連接至插座122，以對電池模組200進行充電。由於電池模組200的頂面215由殼體10的開口11暴露，因此於部分實施例中，插座122亦可直接形成於電池模組200的頂面215上。When the power of the battery module 200 is exhausted, the user can connect an external power source to the socket 122 to charge the battery module 200. Since the top surface 215 of the battery module 200 is exposed by the opening 11 of the casing 10, in some embodiments, the socket 122 can also be directly formed on the top surface 215 of the battery module 200.

當電池模組200需維修或取出時，使用者可通過下述步驟將電池模組200從電池固定座100上分離。首先，請參閱第6A圖，使用者可旋轉驅動部153使插銷151朝向左方移動並離開電池模組200的凹孔216。此時，彈性構件290的彈性力會使本體210相對於活動件280移動，第一導引柱131將從第一位置沿圓弧段261滑動至一中間位置，且電池模組200將相對於電池固定座100繞一第一旋轉軸R1旋轉。由於第一導引柱131是沿圓弧段261滑動，因此前述第一旋轉軸R1係穿過圓弧段261的圓心並垂直於第一導槽250。When the battery module 200 needs to be repaired or removed, the user can separate the battery module 200 from the battery holder 100 through the following steps. First, referring to FIG. 6A, the user can rotate the driving part 153 to move the plug 151 to the left and leave the recessed hole 216 of the battery module 200. At this time, the elastic force of the elastic member 290 will cause the main body 210 to move relative to the movable part 280, the first guide post 131 will slide from the first position along the arc segment 261 to an intermediate position, and the battery module 200 will be relatively The battery holder 100 rotates around a first rotation axis R1. Since the first guide post 131 slides along the arc segment 261, the aforementioned first rotation axis R1 passes through the center of the arc segment 261 and is perpendicular to the first guide slot 250.

如第6A圖所示，此時，滑動件270可接觸第一安裝台110的凸出部113，以使第一導引柱131固定於前述中間位置。電池模組200將暫時不會繼續相對於電池固定座100繞第一旋轉軸R1旋轉，進而可避免電池模組200直接掉落於地面。As shown in FIG. 6A, at this time, the sliding member 270 can contact the protruding portion 113 of the first mounting platform 110, so that the first guiding post 131 is fixed at the aforementioned intermediate position. The battery module 200 will not continue to rotate about the first rotation axis R1 relative to the battery holder 100 temporarily, so as to prevent the battery module 200 from falling directly on the ground.

請參閱第6B圖，接著，使用者可推動滑動件270，使滑動件270相對於本體210移動。滑動件270和凸出部113之間的干涉可被解除，電池模組200可繼續相對於電池固定座100繞第一旋轉軸R1旋轉，且第一導引柱131可從中間位置沿圓弧段261滑動至一第二位置。Please refer to FIG. 6B. Then, the user can push the sliding member 270 to move the sliding member 270 relative to the main body 210. The interference between the sliding member 270 and the protrusion 113 can be released, the battery module 200 can continue to rotate relative to the battery holder 100 around the first rotation axis R1, and the first guide post 131 can follow the arc from the middle position The segment 261 slides to a second position.

前述第二位置係位於圓弧段251和線狀段252的連接處，因此，當電池模組200欲繼續相對於電池固定座100旋轉時，應會繞一第二旋轉軸R2旋轉，其中前述第二旋轉軸R2穿過圓弧段251和線狀段252的連接處並垂直於第一導槽250。The aforementioned second position is located at the junction of the arc segment 251 and the linear segment 252. Therefore, when the battery module 200 intends to continue to rotate relative to the battery holder 100, it should rotate around a second rotation axis R2, where the aforementioned The second rotation axis R2 passes through the connection of the circular arc segment 251 and the linear segment 252 and is perpendicular to the first guide groove 250.

如第6B圖所示，當第一導引柱131位於圓弧段261的第二位置時，電池模組200的抵接部240將會接觸電動自行車B的殼體10，以阻擋電池模組200欲繼續相對於電池固定座100繞第二旋轉軸R2旋轉。藉此，電池模組200將無法繼續相對於電池固定座100旋轉，而會停留於此角度，避免電池模組200掉落的風險。最後，使用者可使第一導引柱131沿第一導槽250的線狀段252移動並離開第一導槽250，進而使電池模組200與電池固定座100分離。As shown in FIG. 6B, when the first guide post 131 is located at the second position of the arc segment 261, the abutting portion 240 of the battery module 200 will contact the housing 10 of the electric bicycle B to block the battery module 200 intends to continue to rotate relative to the battery holder 100 around the second rotation axis R2. In this way, the battery module 200 cannot continue to rotate relative to the battery holder 100, but will stay at this angle, avoiding the risk of the battery module 200 falling. Finally, the user can move the first guide post 131 along the linear section 252 of the first guide groove 250 and leave the first guide groove 250 to separate the battery module 200 from the battery holder 100.

請參閱第7圖，於前述實施例中，電池模組200之本體210內部具有至少兩個電芯組件201和複數個金屬連接組件202、203。每個電芯組件201可包括複數個電芯C，且這些電芯C可通過金屬連接組件202彼此串聯。電芯組件201之間則可透過金屬連接組件203串聯。具體而言，如第8A圖所示，金屬連接組件203可包括一第一板體204、一第二板體205、以及至少一中間板體206，其中中間板體206位於第一板體204和第二板體205之間並連接兩者。Please refer to FIG. 7. In the foregoing embodiment, the body 210 of the battery module 200 has at least two battery cell components 201 and a plurality of metal connection components 202 and 203 inside. Each battery cell assembly 201 may include a plurality of battery cells C, and the battery cells C may be connected in series with each other through the metal connection assembly 202. The battery core components 201 can be connected in series through the metal connection component 203. Specifically, as shown in FIG. 8A, the metal connection assembly 203 may include a first plate 204, a second plate 205, and at least one intermediate plate 206, wherein the intermediate plate 206 is located on the first plate 204 And the second board 205 and connect the two.

第一板體204和中間板體206之間具有一第一彎折線L1，且第二板體205和中間板體206之間具有一第二彎折線L2。中間板體206上形成有至少一刻痕L3，且刻痕L3係不平行於前述第一彎折線L1和第二彎折線L2。於本實施例中，第一彎折線L1和第二彎折線L2彼此平行，且刻痕L3垂直於第一彎折線L1和第二彎折線L2。There is a first bending line L1 between the first plate 204 and the middle plate 206, and a second bending line L2 is between the second plate 205 and the middle plate 206. At least one notch L3 is formed on the middle plate 206, and the notch L3 is not parallel to the aforementioned first bending line L1 and the second bending line L2. In this embodiment, the first bending line L1 and the second bending line L2 are parallel to each other, and the notch L3 is perpendicular to the first bending line L1 and the second bending line L2.

使用時，可將一個電芯組件201A固定於第一板體204上，並將另一個電芯組件201B固定於第二板體205上，且第一板體204和第二板體205可分別與電芯組件201A、201B中的一個電芯C電性連接。接著，使用者可使金屬連接組件203沿著第一彎折線L1和第二彎折線L2彎折，如此一來，金屬連接組件203即可變形為第7、8B圖所示之外型。When in use, one cell assembly 201A can be fixed on the first plate 204, and the other cell assembly 201B can be fixed on the second plate 205, and the first plate 204 and the second plate 205 can be separately It is electrically connected to one cell C in the cell assemblies 201A and 201B. Then, the user can bend the metal connecting component 203 along the first bending line L1 and the second bending line L2, so that the metal connecting component 203 can be deformed into the shape shown in FIGS. 7 and 8B.

由於中間板體206上具有刻痕L3，因此在金屬連接組件203彎折後中間板體206不會向外凸出，亦即中間板體206的法線方向可大致垂直於第一板體204的法線方向或第二板體205的法線方向，有利於電池模組200的小型化。Since the middle plate 206 has a notch L3, the middle plate 206 will not protrude outward after the metal connecting component 203 is bent, that is, the normal direction of the middle plate 206 can be substantially perpendicular to the first plate 204 The normal direction of the second plate 205 or the normal direction of the second plate 205 is beneficial to the miniaturization of the battery module 200.

請參閱第9圖，於本發明一些實施例中，電池模組200中的每個電芯組件201各自具有偶數個電芯C，因此位於電芯組件201一端的電芯C以金屬連接組件203連接後，另一端的電芯C亦需以一金屬連接組件203’連接。Referring to Figure 9, in some embodiments of the present invention, each cell assembly 201 in the battery module 200 has an even number of cells C, so the cell C at one end of the cell assembly 201 is connected to the assembly 203 by metal. After the connection, the cell C at the other end also needs to be connected with a metal connection component 203'.

如第9、10圖所示，金屬連接組件203’包括一第一板體204’、一第二板體205’、以及至少一中間板體206’，其中第一板體204’和第二板體205’可分別固定於電芯組件201A和電芯組件201B上，且可分別與電芯組件201A、201B中的一個電芯C電性連接。As shown in Figures 9 and 10, the metal connection component 203' includes a first plate 204', a second plate 205', and at least one intermediate plate 206', wherein the first plate 204' and the second plate 206' The board 205' can be fixed to the battery cell assembly 201A and the battery cell assembly 201B respectively, and can be electrically connected to one of the battery core assemblies 201A and 201B respectively.

中間板體206’可具有一第一段部2061’和一第二段部2062’。第一段部2061’連接第一板體204’且與第一板體204’一體成型，而第二段部2062’則連接第二板體205’且與第二板體205’一體成型。第一段部2061’上形成有一孔洞208’，而第二段部2062’上則形成有一卡勾209’。當金屬連接組件203彎折後，中間板體206’的第一段部2061’和第二段部2062’可鄰近且重疊，此時使用者即可將前述卡勾209’穿過孔洞208’，以使第一段部2061’和第二段部2062’以卡扣方式結合而形成中間板體206’，並可完成電芯組件201之間的連結(如第9圖所示)。The intermediate plate 206' may have a first section 2061' and a second section 2062'. The first section 2061' is connected to the first plate 204' and is integrally formed with the first plate 204', and the second section 2062' is connected to the second plate 205' and is integrally formed with the second plate 205'. A hole 208' is formed on the first section 2061', and a hook 209' is formed on the second section 2062'. After the metal connecting component 203 is bent, the first section 2061' and the second section 2062' of the middle plate 206' can be adjacent to and overlap each other, and the user can then pass the hook 209' through the hole 208' , So that the first segment portion 2061' and the second segment portion 2062' are combined in a snap-fit manner to form the intermediate plate body 206', and the connection between the cell assemblies 201 can be completed (as shown in FIG. 9).

請參閱第11圖，於本發明另一實施例中，電池模組200中的每個電芯組件201同樣具有偶數個電芯C，只是電芯組件201中的電芯C的排列方式相異於第9圖的電池模組200。如第11圖所示，前述金屬連接組件203’同樣可以利用來連接此種電池模組200中相鄰的電芯組件201。Referring to FIG. 11, in another embodiment of the present invention, each cell assembly 201 in the battery module 200 also has an even number of cells C, but the arrangement of the cells C in the cell assembly 201 is different The battery module 200 in FIG. 9. As shown in FIG. 11, the aforementioned metal connection component 203' can also be used to connect adjacent battery cell components 201 in such a battery module 200.
