Description

电池組件及使用该电池組件的电动工具 技术领域  Battery assembly and power tool using the same
本发明涉及一种电池组件及使用该电池组件的电动工具。  The present invention relates to a battery assembly and a power tool using the battery assembly.
背景技术 Background technique
电动工具， 诸如电钻、 摆动机、 电圆锯、 打草机等， 能够通过使用电池 组件作为电源， 以获得比有绳电动工具更好的灵活性和便携性。  Power tools, such as electric drills, oscillating machines, electric circular saws, lawn mowers, etc., can use the battery pack as a power source to achieve greater flexibility and portability than corded power tools.
电池组件本身具有一定的体积，所以当电池組件被安装至电动工具上时， 电动工具的体积会有所增加， 当使用者需要将电动工具在较小的空间中使用 时， 往往会感到不便； 电动工具也经常将电池组件收容于电动工具的把手部 分内， 当电池組件被安装至电动工具上时， 电动工具的把手体积会有所增加， 当使用者需要将电动工具在较小的空间中使用时， 也会感觉到不便； 同时， 将电池组件收容于电动工具的把手部分内时， 也容易造成把手直径的增加， 使用者在握持把手时， 同样会感觉到不便。  The battery pack itself has a certain volume, so when the battery pack is mounted on the power tool, the size of the power tool is increased, and when the user needs to use the power tool in a small space, it is often inconvenient; The power tool also often houses the battery pack in the handle portion of the power tool. When the battery pack is mounted to the power tool, the handle volume of the power tool increases, when the user needs to place the power tool in a small space. When in use, it is also inconvenient; at the same time, when the battery pack is housed in the handle portion of the power tool, the diameter of the handle is also likely to increase, and the user feels inconvenience when holding the handle.
现有的电池組件的电池单元两端对齐的设置， 将电池組件的电极端子和 电池组件的锁紧装置分别设置于电池单元的两端， 从而导致电池組件的整体 长度较长， 当电池組件安装入电动工具的把手时， 电动工具的把手也会较长， 使得电动工具的体积较大， 影响了电动工具的灵活性和便携性， 使用户的使 用体验较差。  The arrangement of the battery cells of the existing battery assembly is aligned, and the electrode terminals of the battery assembly and the locking device of the battery assembly are respectively disposed at the two ends of the battery unit, thereby causing the overall length of the battery assembly to be long, when the battery assembly is installed. When the handle of the power tool is inserted, the handle of the power tool is also long, which makes the power tool larger in size, which affects the flexibility and portability of the power tool, and the user experience is poor.
同时， 这种电池组件的外壳形状比较规则， 电池组件側壁平整， 两端为 平面且大小相同， 所以在将电池組件安装入电动工具的把手时， 不能有效地 利用把手部分内的空间， 无法将电池組件与电动工具安装的更加紧凑， 从而 导致电动工具的把手较长， 使得电动工具的体积较大， 影响了电动工具的灵 活性和便携性， 使用户的使用体验较差。  At the same time, the shape of the outer casing of the battery assembly is relatively regular, the side wall of the battery assembly is flat, the ends are flat and the same size, so when the battery assembly is mounted into the handle of the power tool, the space in the handle portion cannot be effectively utilized, and the The battery assembly and the power tool are more compactly mounted, resulting in a longer handle of the power tool, which makes the power tool larger in size, affecting the flexibility and portability of the power tool, and the user experience is poor.
同时， 这种电池组件的外壳外形对称， 用户在安装电池组件时， 无法方 便的辨认出安装方向， 容易出现误搡作， 给使用带来了不便， 甚至容易损坏 电动工具或者电池組件； 对于电动工具厂商来说， 需要在电池组件上设置特 别的防误插结构来预防用户误橾作给电动工具或者电池組件带来的伤害， 成 本较高。  At the same time, the outer shape of the battery assembly is symmetrical, and the user cannot easily recognize the installation direction when installing the battery assembly, which is prone to mistakes, which causes inconvenience to the use, and even damages the power tool or the battery assembly; For tool manufacturers, it is necessary to set a special anti-missing structure on the battery component to prevent the user from accidentally causing damage to the power tool or the battery component, and the cost is high.

The first end surface 111 protrudes from the first end surface 111 to the top surface 113 to form a second battery receiving portion 12, which is adjacent to the second end surface 112. The third battery housing portion 13 is formed by projecting in the longitudinal direction to the bottom surface 114.
电池单元 2a、 2b外形呈圆柱形， 具有沿平行于所述纵长方向的 自 身中心 线 2a'、 2b，延伸的主体， 包括平行于 自 身中心线 2a'、 2b，的側壁， 垂直于 自 身中心线 2a，、 2b'且大致呈圆形的下端面 21a、 21b 和上端面 22a、 22b; 下 端面 21a、 21b靠近底面 114, 上端面 22a、 22b分别与下端面 21a、 21b相对 设置。  The battery cells 2a, 2b have a cylindrical shape and have a body extending along the center line 2a', 2b parallel to the longitudinal direction, including a side wall parallel to the center line 2a', 2b thereof, perpendicular to the center thereof. Lines 2a, 2b' and substantially circular lower end faces 21a, 21b and upper end faces 22a, 22b; lower end faces 21a, 21b are adjacent to the bottom face 114, and upper end faces 22a, 22b are disposed opposite the lower end faces 21a, 21b, respectively.
电池单元 2a、 2b收容于外壳 1 内， 电池单元 2b在所述纵长方向上相对 于电池单元 2a具有一定的位移， 从而使得电池单元 2a的下端面 21a设置于 底面 114上， 电池单元 2b的下端面 21b设置于第二端面 112上， 此时， 电池 单元 2a位于第一端面 111 与底面 114 之间， 电池单元 2b位于第二端面 112 和顶面 113之间； 此时， 电池单元 2a的上端面 22a位于电池单元 2b的上端 面 22b和下端面 21b之间。 The battery unit 2a, 2b is housed in the outer casing 1. The battery unit 2b has a certain displacement with respect to the battery unit 2a in the longitudinal direction, so that the lower end surface 21a of the battery unit 2a is disposed on the bottom surface 114, and the battery unit 2b The lower end surface 21b is disposed on the second end surface 112, at this time, the battery The unit 2a is located between the first end surface 111 and the bottom surface 114, and the battery unit 2b is located between the second end surface 112 and the top surface 113; at this time, the upper end surface 22a of the battery unit 2a is located at the upper end surface 22b and the lower end surface 21b of the battery unit 2b. between.
第二电池收容部 12和第三电池收容部 13在第一端面 111 上的投影面积 小于第一端面 111 的面积， 在本实施方式中， 第二电池收容部 12在第一端面 111 上的投影面积约为第一端面 111 面积的一半， 第三电池收容部 13在第一 端面 111 上的投影面积约为第一端面 111 面积的一半， 第二电池收容部 12 与 第三电池收容部 13相互对称的设置，所以第二电池收容部 12在第一端面 111 上的投影与第三电池收容部 13在第一端面 111 上的投影.互补； 当然， 本领域 技术人员容易想到的是， 第二电池收容部 12和第三电池收容部 13在第一端 面 111 上的投影面积也可以是大于或小于第一端面 111 面积的一半的， 此时， 第二电池收容部 12在第一端面 111 上的投影与第三电池收容部 13在第一端 面 111 上的投影会有部分的重合或者间隔。  The projection area of the second battery housing portion 12 and the third battery housing portion 13 on the first end surface 111 is smaller than the area of the first end surface 111. In the present embodiment, the projection of the second battery housing portion 12 on the first end surface 111 The area of the first end surface 111 is about half of the area of the first end surface 111. The projected area of the third battery receiving portion 13 on the first end surface 111 is about half of the area of the first end surface 111. The second battery receiving portion 12 and the third battery receiving portion 13 are mutually Symmetrically disposed, so that the projection of the second battery receiving portion 12 on the first end surface 111 is complementary to the projection of the third battery receiving portion 13 on the first end surface 111; of course, those skilled in the art will readily recognize that the second The projected area of the battery receiving portion 12 and the third battery receiving portion 13 on the first end surface 111 may be larger or smaller than half of the area of the first end surface 111. At this time, the second battery receiving portion 12 is on the first end surface 111. The projection of the third battery housing portion 13 on the first end surface 111 may partially overlap or be spaced.
电池单元 2a、 2b 为锂离子电池单元， 具有金属锂氡化物和 /或锂离子磷 酸盐和 /或其他锂基化学成分， 例如作为阴极活性材料的可以是铉钴复合氡化 物、 锂镍复合氧化物、 锂锰复合氣化物之一或者他们的混合物或者其他金属 锂氣化物， 作为阴极活性材料的也可以是锂离子磷酸盐； 作为阳极材料的可 以是石墨碳材料； 电池单元 2a、 2b具有大约 65mm 的长度以及大约 18mm的 橫截面直径。  The battery cells 2a, 2b are lithium ion battery cells, having metal lithium telluride and / or lithium ion phosphate and / or other lithium-based chemical components, for example, as a cathode active material may be samarium cobalt composite telluride, lithium nickel composite oxidation One of the lithium manganese composite gasifications or a mixture thereof or other metal lithium vapor, as the cathode active material may also be a lithium ion phosphate; as the anode material may be a graphite carbon material; the battery cells 2a, 2b have approximately A length of 65 mm and a cross-sectional diameter of approximately 18 mm.
能够想到的是， 电池单元 2a、 2b也可以是其它任何可再充电电池单元化 学物质类型的， 例如镍-鎘 (NiCD), 镍 -金属氢化物 （NiMH)、 其它锂基化 合物质、 其它可再充电电池单元化学物质等： 电池单元 2a、 2b也可以是其它 尺寸的可再充电电池单元， 例如具有大约 65mm 的长度以及大约 26mm 的橫 截面直径等； 能够想到的是， 电池单元 2a、 2b也可以是其他类型的蓄电单元， 例如超级电容。  It is conceivable that the battery cells 2a, 2b may also be of any other rechargeable battery cell type, such as nickel-cadmium (NiCD), nickel-metal hydride (NiMH), other lithium-based compounds, others.

在本实施方式中， 电池单元 2b在所述纵长方向上相对于电池单元 2a的 位移长度约为电池单元 2a长度的三分之一， 电池单元 2a 的下端面 21a至电 池单元 2b 的上端面 22b 的距离约为电池单元 2a 长度的 1.3 倍； 本领域技术 人员 能够想到的是， 这个长度可以根据需要而进行调整，例如当第二端面 112 和底面 114之间的距离发生变化时，电池单元 2b在所述纵长方向上相对于电 池单元 2a的位移长度会发生变化， 但电池单元 2b在所述纵长方向上相对于 电池单元 2a的位移长度不会过大， 否则将使电池组件 100的长度增加， 一般 来说， 电池单元 2b在所述纵长方向上相对于电池单元 2a的位移长度不大于 电池单元 2a长度的二分之一， 所以， 电池单元 2a的下端面 21a至电池单元 2b的上端面 22b 的距离介于电池单元 2a长度的 1.3倍至 1.5倍之间。 In the present embodiment, the displacement length of the battery unit 2b with respect to the battery unit 2a in the longitudinal direction is about one third of the length of the battery unit 2a, and the lower end surface 21a of the battery unit 2a to the upper end surface of the battery unit 2b. The distance of 22b is about 1.3 times the length of the battery unit 2a; it will be appreciated by those skilled in the art that this length can be adjusted as needed, for example, when the distance between the second end face 112 and the bottom face 114 changes, the battery unit 2b varies in the longitudinal direction with respect to the displacement length of the battery unit 2a, but the battery unit 2b is opposite to the longitudinal direction The displacement length of the battery unit 2a is not excessive, otherwise the length of the battery assembly 100 will increase. Generally, the displacement length of the battery unit 2b relative to the battery unit 2a in the longitudinal direction is not greater than the length of the battery unit 2a. One-half, therefore, the distance from the lower end surface 21a of the battery unit 2a to the upper end surface 22b of the battery unit 2b is between 1.3 times and 1.5 times the length of the battery unit 2a.
电极端子 3设置于外壳 1 内， 位于电池单元 2a的上端面 22a之上， 并通 过第一端面 111 上的开孔与电动工具或者充电装置电性连接。 电极端子 3 可 以包括正、 负极端子、多个逻辑端子（图中未示出）以及安装上述端子的 PCB。  The electrode terminal 3 is disposed in the outer casing 1 and located above the upper end surface 22a of the battery unit 2a, and is electrically connected to the power tool or the charging device through the opening in the first end surface 111. The electrode terminal 3 may include positive and negative terminals, a plurality of logic terminals (not shown), and a PCB on which the above terminals are mounted.
锁紧装置 4设置于外壳 1 上， 收容于第三电池收容部 13 与第二端面 112 之间所形成的凹口部位内， 与第二端面 112 滑动连接； 锁紧装置 4 包括弹性 件 42和卡钩 41, 当使用者未按压锁紧装置 4 时， 卡钩 41 凸出于外壳 1 的侧 壁， 当使用者按压锁紧装置 4 时， 弹性件 42被压缩， 卡钩 41 缩回外壳 1 的 侧壁之下，从而实现将电池組件 100锁紧或者释放于电动工具或者充电装置。  The locking device 4 is disposed on the outer casing 1 and is received in the notch portion formed between the third battery receiving portion 13 and the second end surface 112, and is slidably connected to the second end surface 112. The locking device 4 includes an elastic member 42 and The hook 41 protrudes from the side wall of the outer casing 1 when the user does not press the locking device 4.

从人机工程学的角度来说， 人们在评估使用电池组件作为电源的手持式 电动工具的性能时，往往使用手持式电动工具的功率对重量的比率作为标准。 手持式电动工具的功率对重量的比率为手持式电动工具的最大输出功率除以 手持式电动工具的重量 （手持式电动工具的重量等于手持式电动工具本身的 重量加上电池組件的重量）。  From an ergonomic point of view, when evaluating the performance of a hand-held power tool using a battery pack as a power source, the power-to-weight ratio of the hand-held power tool is often used as a standard. The power-to-weight ratio of a hand-held power tool is the maximum output power of the hand-held power tool divided by the weight of the hand-held power tool (the weight of the hand-held power tool is equal to the weight of the hand-held power tool itself plus the weight of the battery assembly).
日 常工作中 300 瓦特的输出功率能够满足大部分工作情况下的需求， 所 以能满足 300 瓦特的输出功率的手持式电动工具中， 工具重量轻的， 具有较 佳的功率对重量的比率。 下表一示出 了本发明实施方式中手持式电动工具 30 1 以及传统的 1 2仗手持式电动工具 （诸如 PO SITEC 生产的型号为 CDT36 的 电钻）、 传统的 1 8 伏手持式电动工具 （诸如 BO SCH 生产 的型号为 GSB 1 8-2-LI的电钻） 的最大输出功率以及工具重量的数据。 In the daily work, the output power of 300 watts can meet the needs of most working conditions, so in the hand-held power tools that can meet the output power of 300 watts, the tool is light in weight and has a better ratio of power to weight. Table 1 below shows a hand-held power tool 30 1 and a conventional 12-inch hand-held power tool (such as a CDT36-type electric drill manufactured by PO SITEC) and a conventional 18-volt hand-held power tool in the embodiment of the present invention ( Models such as BO SCH are GSB 1 8-2-LI electric drill) Maximum output power and tool weight data.

在进行手持式电动工具设计中需要考虑若干参数或技术方面的特征， 例 如电机、 机壳、 减速机构等中的部件通常构造为能够承受手持式电动工具使 用的电池组件输出的最大电流， 而使用尽可能轻的材料和子系统部件， 从而 获得人机工程学的优势 （即较轻的手持式电动工具重量）， 在改变手持式电动- 工具中的电机、 机壳、 减速机构等中的部件需要承受的最大电流的情况下， 往往需要更换电机、 机壳、 减速机构等中的部件， 从而带来手持式电动工具 重量的变化。  There are a number of parameters or technical aspects that need to be considered in the design of a hand-held power tool. Components such as motors, housings, speed reduction mechanisms, etc. are typically constructed to withstand the maximum current output from the battery components used by hand-held power tools. Lightweight materials and subsystem components for ergonomic advantages (ie, lighter weight of hand-held power tools), changing the need for components in motors, housings, speed reduction mechanisms, etc. in hand-held power-tools In the case of the maximum current that is tolerated, it is often necessary to replace components in the motor, the casing, the speed reduction mechanism, etc., thereby causing a change in the weight of the hand-held power tool.
对于传统的 12 仗手持式电动工具来说， 由于日 常的工作中经常会需要 300 瓦特左右的功率输出， 所以在日 常的工作中常常会造成工具工作在大电 流情况下， 例如堵转的情况下， 传统的 12伏手持式电动工具的输出电流会在 短时间内超过 25安培， 所以相应的其电机、 机壳、 减速机构等中的部件也需 要满足能够承受电池组件的最大输出电流的条件。而本发明所提供的 1 6伏手 持式电动工具， 在输出 300 瓦特左右的功率时， 其电池组件输出电流约为 20 安培， 所以其材料与子系统部件与传统的 12伏手持式电动工具相似， 其重量 上的差別主要在于电池組件多出的电池单元的重量， 以及由于不同电池单元 和 /或电池組件的制造商存在的差別， 例如电池组件的外壳的厚度、 材质、 散 热结构的不同等等。所以本发明实施方式提供的 1 6伏手持式电动工具的重量 较传统的 12仗手持式电动工具增加了 0.2 千克。  For the traditional 12-inch hand-held power tool, because the daily work often requires about 300 watts of power output, it often causes the tool to work under high current conditions in daily work, such as blocking. The output current of the traditional 12-volt handheld power tool will exceed 25 amps in a short time, so the corresponding components in the motor, the casing, the speed reduction mechanism, etc., also need to meet the conditions of being able to withstand the maximum output current of the battery component. The 16 volt hand-held power tool provided by the present invention has a battery assembly output current of about 20 amps when outputting about 300 watts of power, so the material and subsystem components are similar to conventional 12 volt hand-held power tools. The difference in weight is mainly due to the weight of the battery unit that is extra in the battery assembly, and the difference in the manufacturer of different battery units and/or battery components, such as the thickness, material, and heat dissipation structure of the battery assembly. Wait. Therefore, the weight of the 16 volt hand-held power tool provided by the embodiment of the present invention is increased by 0.2 kg compared with the conventional 12-inch hand-held power tool.
对于传统的安装有 12 仗手持式电动工具来说， 本发明实施方式提供的 1 6 仗手持式电动工具还具有更强的单包工作能力， 下表二示出 了传统的 12 伏手持式电动工具以及本发明实施方式提供的 1 6 伏手持式电动工具在同样 列数据用于分析与 1 2伏电池组件和 1 6伏电池組件两种电池组件与化学特性 相对独立的电池组件运行时间特性。 为 了比较， 使用相同的内阻和容量特性 的电池组进行分析）：  For the conventional 12-inch hand-held power tool, the 16-inch hand-held power tool provided by the embodiment of the present invention also has a stronger single-pack working capability, and the following table 2 shows the conventional 12-volt hand-held electric device. The tool and the 16 volt hand-held power tool provided by the embodiments of the present invention are used in the same column data to analyze the runtime characteristics of the battery assembly that are relatively independent of the two battery components and the chemical characteristics of the 12 volt battery component and the 16 volt battery component. For comparison, use the same internal resistance and capacity characteristics of the battery pack for analysis):

300 25 20 0 180 对于相同的输出功率， 例如 300 瓦特输出功率时， 16仗手持式电动工具 抽取的电流约为 20安培，而 12仗手持式电动工具需抽取的电流约为 25安培， 而此时 12仗手持式电动工具往往不能正常进行工作；当手持式电动工具工作 在 200 瓦特的输出功率时， 16伏手持式电动工具抽取的电流约为 13.5 安培， 而 12伏手持式电动工具需抽取的电流约为 17安培， 16仗手持式电动工具抽 取更少的电流， 因此 16仗手持式电动工具的 I2R热损失 （热损失可以由电流 的平方乘以阻抗来表示） 小于带有 12仗手持式电动工具的热损失， 因此， 16 伏手持式电动工具相对于 12 伏手持式电动工具能够具有更长的单包工作时 间。 300 25 20 0 180 For the same output power, for example 300 watts of output power, the 16 仗 hand-held power tool draws about 20 amps, while the 12 仗 hand-held power tool draws about 25 amps. Hand-held power tools often fail to work properly; when a hand-held power tool is operated at 200 watts of output power, the 16-volt handheld power tool draws approximately 13.5 amps of current, while the 12-volt hand-held power tool requires extraction. The current is about 17 amps, and the 16-inch hand-held power tool draws less current, so the I 2 R heat loss of the 16-inch hand-held power tool (heat loss can be expressed by the square of the current multiplied by the impedance) is less than 12热The heat loss of the hand-held power tool, therefore, the 16 volt hand-held power tool can have a longer single-pack working time compared to the 12-volt hand-held power tool.
对于传统的 18伏手持式电动工具来说，虽然手持式电动工具日 常工作往 往仅需要约 300 瓦特的输出功率， 但是为了保证手持式电动工具具有能够承 受最高功率水平的能力， 所以其相应的电机、 机壳、 减速机构等中的部件也 需要具有能够承受最高功率水平的能力。所以与传统的 12仗手持式电动工具 以及本发明实施方式提供的 16伏手持式电动工具相比，其重量上的差別主要 在于下面两个方面： 第一， 电池组件的重量， 多出的电池单元的重量， 以及 由于不同电池单元和 /或电池组件的制造商存在的差別， 例如电池盒 /或电池 组件的外壳的厚度、 材质、 散热的不同等等。 第二， 手持式电动工具使用 了 能够适应更高功率水平的材料与子系统部件而带来的重量增加， 所以本发明 实施方式提供的 16伏手持式电动工具与传统的 18伏手持式电动工具相比， 重量减轻了 0.3 千克。 同样， 由于上述两个原因带来了手持式电动工具整体 体积的增大。  For traditional 18-volt handheld power tools, although handheld power tools often require only about 300 watts of output per day, in order to ensure that handheld power tools have the ability to withstand the highest power levels, their corresponding motors Components in the casing, reduction mechanism, etc. also need to be able to withstand the highest power levels. Therefore, compared with the conventional 12-inch hand-held power tool and the 16-volt hand-held power tool provided by the embodiment of the present invention, the difference in weight mainly lies in the following two aspects: First, the weight of the battery component, the extra battery The weight of the unit, as well as differences in the manufacturer of different battery cells and/or battery components, such as the thickness, material, and heat dissipation of the battery case/or battery case. Second, hand-held power tools use weights that can accommodate higher levels of power and subsystem components, so the 16 volt handheld power tool and conventional 18 volt handheld power tool are provided by embodiments of the present invention. In comparison, the weight is reduced by 0.3 kg. Also, the overall volume of the hand-held power tool is increased due to the above two reasons.
