Description

Technical Field

[0001] The invention relates to a tool system. Background Art

[0002] Pole saws and pole trimmers are formed by configuring extension poles on the basis of chain saws and pruning machines. Such a setting allows users to easily saw the trunks and branches of taller trees, eliminating the danger of users climbing trees for high-altitude operations, and thus is widely welcomed by users. Pole saws and pole trimmers usually place the motor at the head end, and place the power source such as the battery assembly at the handle end. In order to facilitate carrying and storage, the extension pole is usually designed to be foldable or multi-section detachable. The wire is passed through the inside of the pole body, and the electrical connection is made through an electrical connector at the plug. At the same time, according to the different needs of customers, pole saws and pole trimmers usually have a variety of voltage configurations, such as: 24V, 40V, 48V, etc. In order to reduce the design cost, production cost and storage cost of the product, pole saws and pole trimmers with different voltage configurations usually share a platform, such as: operating rod, electrical connector, etc. However, such a setting will cause the operating rod of the motor with different input voltages to be inserted into the operating rod of the battery assembly with different output voltages, thereby causing damage to the machine.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] See also Figure 1 , Figure 2 as well as Figure 3 As shown, the present invention discloses a tool system 1, including a first tool 100, a second tool 200 and a third tool 300. The first tool 100 includes a first operating mechanism 110, a first operating rod 120, a first battery assembly 130, a first handle assembly 140 and a first connector 150. The first operating mechanism 110 is used to perform the function of the first tool 100. In this embodiment, the first operating mechanism 110 is a chain saw, but in other embodiments, the first operating mechanism 110 can also be an operating mechanism that performs other functions, and the present invention is not limited to this. The first operating rod 120 includes a first rod 121 and a second rod 122 that matches the first rod 121. The first operating mechanism 110 is installed at one end of the first rod 121. A first fixing member 1211 is provided at one end of the first rod 121 away from the first operating mechanism 110. The first battery assembly 130 and the first handle assembly 140 are fixedly installed at one end of the second rod 122. A second fixing member 1221 is provided at one end of the second rod 122 away from the first battery assembly 130. The first fixing member 1211 cooperates with the second fixing member 1221 to fix the first rod 121 and the second rod 122 together, thereby forming an integral operating rod. In the present embodiment, the first fixing member 1211 is a screw sleeve provided with an internal thread, and the second fixing member 1221 is a screw rod provided with an external thread. Of course, it is understandable that the first rod 121 and the second rod 122 can be fixed together in a variety of ways, and the screw sleeve and the screw rod are only one of the embodiments. The present invention does not limit the specific structure of the first fixing member 1211 and the second fixing member 1221. In other embodiments, in order to avoid relative rotation between the first rod 121 and the second rod 122, the first rod 121 is also provided with a first anti-rotation member (not shown), and the second rod 122 is provided with a second anti-rotation member (not shown), so that the first rod 121 and the second rod 122 cannot rotate relative to each other through the cooperation of the first anti-rotation member and the second anti-rotation member.

[0024] See also Figure 1 As shown, the first battery assembly 130 is used to provide power to the first operating mechanism 110. The first handle assembly 140 is used to control the operation of the first operating mechanism 110. Figure 1 as well as Figure 5As shown, the first handle assembly 140 includes a handle shell 141, a first micro switch 142, a first trigger 143 and a first self-locking member 144. The first micro switch 142 is used to control the on and off of the electrical connection between the first battery assembly 130 and the first operating mechanism 110. The first trigger 143 is pivotally mounted on the handle shell 141 through a first pivot 1431, and includes an operating arm 1432 and a supporting arm 1433 located on both sides of the first pivot 1431. When the user presses the operating arm 1432, the first trigger 143 rotates around the first pivot 1431, so that the supporting arm 1433 supports the first micro switch 142, thereby electrically connecting the first battery assembly 130 to the first operating mechanism 110, so that the first operating mechanism 110 starts to work. In this embodiment, the first pivot 1431 is a pivot hole, but in other embodiments, the first pivot 1431 can also be a pivot. Preferably, the first handle assembly 140 also includes an elastic element 145 that cooperates with the first trigger 143. When the user presses the operating arm 1432, the elastic element 145 is elastically deformed under the action of the operating arm 1432; when the user releases the operating arm 1432, the operating arm 1432 is reset under the action of the elastic element 145. The first self-locking member 144 is pivotally mounted on the handle shell 141 through the second pivot member 1441, and includes a pressing arm 1442 and a locking arm 1443 located on both sides of the second pivot member 1441. In this embodiment, the second pivot member 1441 is a pivot hole, and in other embodiments, the second pivot member 1441 can also be a pivot. A lock button 14421 is pivotally mounted on the pressing arm 1442. A locking portion 14431 that cooperates with the abutting arm 1433 is provided at one end of the locking arm 1443 away from the second pivot member 1441. When the user rotates the lock button 14421 and makes the lock button 14421 abut against the second rod 122, the locking portion 14431 cooperates with the abutting arm 1433, so that the first trigger 143 cannot rotate around the first pivot 1431, and the first trigger 143 is in a locked state. When the user rotates the lock button 14421 and makes the lock button 14421 parallel to the second rod 122, the locking portion 14431 is out of contact with the abutting arm 1433, and the first trigger 143 can rotate around the first pivot 1431, and the first trigger 143 is in an unlocked state.

[0025] See also Figure 2 , Figure 3 as well as Figure 4As shown, the first connector 150 includes a connector module 151 installed at an end of the first rod 121 away from the first operating mechanism 110 and a connector module 2 152 installed at an end of the second rod 122 away from the first battery assembly 130. The connector module 151 includes a first insulating body 1511 and a first terminal group 1512 arranged on the first insulating body 1511. The first insulating body 1511 is provided with a first receiving groove 1513 for receiving the connector module 2 152. The first receiving groove 1513 is a non-rotationally symmetrical figure about the axis of the first rod 121, so that the docking mode of the connector module 151 and the connector module 2 152 is unique, that is, after the connector module 151 rotates around the axial direction of the first rod 121 by an angle α, it cannot be docked with the connector module 2 152. The angle α is greater than 0 degrees and less than 360 degrees. The first terminal group 1512 includes an A terminal, a B terminal and a C terminal, and A, B, and C are only used to distinguish different conductive terminals. Terminals A and B are connected to the positive and negative electrodes of the operating mechanism 110, and terminal C is idle. Although in this embodiment, the first terminal group 1512 includes only three terminals, in other embodiments, the number of terminals in the first terminal group 1512 can be set as needed.

[0026] See also Figure 2 , Figure 3 as well as Figure 4 As shown, the connector module 2 152 includes a second insulating body 1521 and a second terminal group 1522 arranged on the second insulating body 1521. The second terminal group 1522 includes an A' terminal that matches the A terminal, a B' terminal that matches the B terminal, and a C' terminal that matches the C terminal. The A' terminal and the B' terminal are connected to the positive and negative poles of the first battery assembly 130, and the C' terminal is idle. When the connector module 151 and the connector module 2 152 are connected to each other, the A terminal is electrically connected to the A' terminal, and the B terminal is electrically connected to the B' terminal, so that the first battery assembly 130 can supply power to the first operating mechanism 110.

[0027] Preferably, a first stopper 15131 is provided in the first receiving groove 1513, and a second stopper 15211 matching the first stopper 15131 is provided in the second insulating body 1521. The first stopper 15131 and the second stopper 15211 cooperate with each other so that the docking mode between the connector module 1 151 and the connector module 2 152 is unique. In this embodiment, the first stopper 15131 is a partition plate, which divides the first receiving groove 1513 into three accommodating cavities 15132 that only accommodate one terminal. The second insulating body 1521 is provided with three docking platforms 15212. The docking platform 15212 is accommodated in the accommodating cavity 15132 so that the first terminal group 1512 and the second terminal group 1522 are matched, so that the first battery assembly 130 can supply power to the first operating mechanism 110. The second stopper 15211 is a positioning groove formed by the gap between the docking platforms 15212 and matched with the partition plate.

[0028] In this embodiment, connector module 1 151 and connector module 2 152 are configured to have a non-rotationally symmetrical shape by setting the first receiving groove 1513 to a non-rotationally symmetrical shape, thereby making the docking mode between connector module 1 151 and connector module 2 152 unique. However, in other embodiments, the A, B, and C terminals may also form an isosceles triangle, and a non-equilateral triangle. Such a configuration may also make the docking mode between connector module 1 151 and connector module 2 152 unique. Alternatively, the connection lines of the A, B, and C terminals form a triangle, and the triangle is a non-rotationally symmetrical shape. Of course, it is understandable that the sizes of the A, B, and C terminals may also be configured to be inconsistent, thereby making the docking mode between connector module 1 151 and connector module 2 152 unique. In fact, there are many structures that make the docking mode between connector module 1 151 and connector module 2 152 unique, and the present invention does not limit this.

[0029] See also Figure 1As shown, the second tool 200 includes a second operating mechanism 210, a second operating rod 220, a second battery assembly 230, a second handle assembly 240 and a second connector (not shown). The second operating mechanism 210 is used to perform the function of the second tool 200. In this embodiment, the second operating mechanism 210 is also a chain saw. However, in other embodiments, the functions of the first operating mechanism 110 and the second operating mechanism 210 can also be set to be different. For example, the first tool 100 is a pole-type electric saw, and the second tool 200 is a pole-type pruning machine. The second battery assembly 230 is used to provide power to the second operating mechanism 210. The structure of the second operating rod 220 is the same as that of the first operating rod 120, including a third rod 221 and a fourth rod 222 matched with the third rod 221. The second operating mechanism 210 is provided at one end of the third rod 221, and the second battery assembly 230 and the second handle assembly 240 are provided at one end of the fourth rod 222. The structure of the second handle assembly 240 and the second connector is the same as that of the first handle assembly 140 and the first connector 150. The second connector includes a connector module 1 (not shown) disposed at an end of the third rod 221 away from the second operating mechanism 210 and a connector module 2 (not shown) disposed at an end of the fourth rod 222 away from the second battery assembly 230 .

[0030] See also Figure 1 As shown, the third tool 300 includes a third operating mechanism 310, a third operating rod 320, a third battery assembly 330, a third handle assembly 340 and a third connector (not shown). The third operating mechanism 310 is used to perform the function of the third tool 300. The third operating mechanism 310 can be the same as the first operating mechanism 110 and the second operating mechanism 210, or can be set to be different. The third battery assembly 330 is used to provide power to the third operating mechanism 310. The structure of the third operating rod 320 is the same as that of the first operating rod 120 and the second operating rod 220, including a fifth rod 321 and a sixth rod 322 matched with the fifth rod 321. The third operating mechanism 310 is provided at one end of the fifth rod 321, and the third battery assembly 330 and the third handle assembly 340 are provided at one end of the sixth rod 322. The structures of the third handle assembly 340 and the third connector are the same as those of the first handle assembly 140 and the first connector 150. The third connector includes a connector module 1 (not shown) disposed at an end of the fifth rod 321 away from the third operating mechanism 310 and a connector module 2 (not shown) disposed at an end of the sixth rod 322 away from the third battery assembly 330 .

[0031] The first tool 100, the second tool 200 and the third tool 300 are different in that: the voltage of the first battery assembly 130, the voltage of the second battery assembly 230 and the voltage of the third battery assembly 330 are different; the terminals of the first connector 150 electrically connected to the first operating mechanism 110, the terminals of the second connector electrically connected to the second operating mechanism 210 and the terminals of the third connector electrically connected to the third operating mechanism 310 are different. In this way, the first tool 100, the second tool 200 and the third tool 300 can share the same platform during production, thereby reducing the design cost, production cost and storage cost, and the electric tools of different voltages will not be powered even if they are plugged into each other, thereby avoiding the problem of damage to the electric tools due to misplugging. In this embodiment, the voltage of the first battery assembly 130 is 24V, the voltage of the second battery assembly 230 is 40V, and the voltage of the third battery assembly 330 is 48V. However, it can be understood that in other embodiments, the voltages of the first battery assembly 130, the second battery assembly 230 and the third battery assembly 330 can be set as needed. In this embodiment, the A and B terminals of the first connector 150 are electrically connected to the first operating mechanism 110, and the A' and B' terminals are electrically connected to the first battery assembly 130. The B and C terminals of the second connector are electrically connected to the second operating mechanism 210, and the B' and C' terminals are electrically connected to the second battery assembly 230. The A and C terminals of the third connector are electrically connected to the third operating mechanism 310, and the A' and C' terminals are electrically connected to the third battery assembly 330. With such a configuration, when the user inserts the first rod 121 of the first tool 100 into the second rod 222 of the second tool 200, it will be found that the first operating mechanism 110 cannot be powered on, thereby discovering the problem of mis-insertion. At the same time, since power cannot be supplied in the case of mis-insertion, the problem of damage to the power tool due to mis-insertion can be effectively avoided.

[0032] Compared to the prior art, the first tool 100, the second tool 200, and the third tool 300 of the tool system 1 of the present invention can not only share the same platform, thereby reducing design costs, production costs, and storage costs, but also power tools of different voltages will not be powered on when plugged into each other, thereby avoiding the problem of power tool damage caused by wrong plugging.

[0033] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
