[0036] It should be noted that in the present invention, the battery cell assembly 600 is built into the rod body, so that the weight is dispersed. The traditional technology is to tie the battery to the outside of the fishing rod, which is more laborious to use and the experience is not good.

[0037] Among them, Figure 3 and Figure 4 As shown, the controller assembly 400 includes: a fixing seat 410, a controller (not shown), an elastic switch 420 and a safety switch 430.

[0040] like Figure 3 As shown, the battery assembly 600 includes a battery housing 610 and a plurality of lithium batteries 620. The lithium batteries 620 are installed in the battery housing 610.

When the battery cell assembly 600 is disassembled, the built-in disk 520 will slide and rotate along the ridge 101, thereby contacting and driving the extended trigger piece 433.

[0042] Preferably, a blocking ring 102 (such as Figure 6 As shown), the blocking ring 102 is used to prevent the inner push kit 510 from being separated from the ridge 101, that is, to limit the inner push kit 510 to slide only in the area of ​​the ridge 101.

[0043] In this embodiment, if Figure 5 and Figure 6 As shown, a plug rod 611 is provided on the cell housing 610, and a latching tooth 612 is provided at the end of the plug rod 611. A connecting sleeve 522 is provided on the built-in disk 520, and an avoidance tooth groove 523 adapted to the latching tooth 612 is provided on the end surface of the connecting sleeve 522. When the cell assembly 600 is installed, the plug rod 611 passes through the inner push kit 510 and is connected to the connecting sleeve 522 of the built-in disk 520, and after the built-in disk 520 rotates, the latching tooth 612 will be staggered with the avoidance tooth groove 523, so that the plug rod 611 is locked with the connecting sleeve 522.

[0044] Preferably, Figure 6 As shown, a negative electrode terminal 613 is provided on the battery cell shell 610, and the negative electrode of the battery 620 is connected to the negative electrode terminal 613.

[0046] In this embodiment, if Figure 1 As shown, the fishing reel assembly 300 includes: a fishing reel body 310, a handle 320 and a built-in motor (not shown in the figure), the controller assembly 400 and the battery assembly 600 are both electrically connected to the built-in motor, the built-in motor is driven and connected to the fishing reel body 310, and the handle 320 is arranged on the fishing reel body 310. Preferably, a fishing line (not shown in the figure) is wound around the fishing reel body 310, and a guide ring 210 is arranged on the telescopic rod 200, and the fishing line passes through the guide ring 210.

[0047] Next, in combination with the above structure, the main operating principle of the electric fishing rod 10 with built-in battery of the present invention is described:

[0048] Before use, the user needs to install the battery assembly 600 into the rod body 100, and the battery assembly 600 is electrically connected to the controller assembly 400 through the safety auxiliary assembly 500. At this time, the safety switch 430 should be turned to the power-off position, so that even if the elastic switch 420 is pressed, the fishing reel assembly 300 will not be started;

[0049] When in use, the user switches the safety switch 430 to the power-on position, and then during fishing, the controller can be triggered by pressing the elastic switch 420, thereby starting the fishing reel assembly 300, so that the built-in motor drives the fishing reel body 310 and the handle 320 to rotate to gather the fishing line. After releasing the elastic switch 420, the fishing reel body 310 returns to a free rotation state to achieve line release or manual hand control.

[0050] It is worth noting that in the present invention, the electric fishing rod 10 with built-in battery cells can eliminate the phenomenon of the fishing reel assembly 300 being accidentally started during the replacement of the battery cells, which is mainly achieved through the cooperation of the safety auxiliary assembly 500 and the safety switch 430. The specific working principle is as follows (refer to Figure 5 , Figure 7 and Figure 8 shown):

[0051] When installing the battery assembly 600, the user needs to push the battery housing 610 with the lithium battery 620 installed into the rod body 100. The front end of the battery housing 610 will contact and abut against the inner push kit 510, thereby pushing the inner push kit 510 to move forward together. During the movement, at the beginning, the inner push kit 510 and the built-in disk 520 are both in the area of ​​the ridge 101, and the tooth tips of the active bevel teeth 511 and the tooth tips of the passive bevel teeth 521 abut against each other (such as Figure 7As shown), and under the action of the reset elastic member 530, the built-in disk 520 always has a tendency to approach the inner push kit 510; when moving, the inner push kit 510 pushes the built-in disk 520 forward, the reset elastic member 530 is compressed, and the built-in disk 520 gradually leaves the area of ​​the ridge 101; when moving into place, the built-in disk 520 completely leaves the area of ​​the ridge 101, and the built-in disk 520 is no longer restricted by the ridge 101 (it has the conditions for rotation), and under the action of the reset elastic member 530, the tooth tip of the passive bevel tooth 521 will slide to the tooth gap depression of the active bevel tooth 511, thereby causing the built-in disk 520 to rotate an angle. At this time, the slide groove 501 of the built-in disk 520 is staggered from the ridge 101. When the user no longer pushes the battery cell housing 610, the reset elastic member 530 prompts the built-in disk 520, the inner push kit 510 and the battery cell housing 610 to retreat a short distance. At this time, the built-in disk 520 is supported by the ridge 101 and rotates again by an angle until the tooth recess of the passive bevel teeth 521 is clamped with the end of the ridge 101, and the plug-in rod 611 is clamped with the connecting sleeve 522. In this way, the installation of the battery cell assembly 600 is completed;

[0052] During the installation, the built-in disk 520 leaving the ridge 101 area will contact the extended trigger plate 433 of the safety switch 430, and under the action of the friction between the two, the rotation of the built-in disk 520 will cause the safety switch 430 to rotate. When the safety switch 430 is originally in the power-on position, the friction drives the safety switch 430 to rotate, so that the safety switch 430 switches to the power-off position; when the safety switch 430 is originally in the power-off position, because the lever 432 is already in the extreme position and has no room for movement, the friction cannot drive the safety switch 430 to rotate, that is, the safety switch 430 is still in the power-off position;

[0053] When removing the battery cell assembly 600, the user pushes the battery cell housing 610 inward again, and the battery cell housing 610 drives the inner push kit 510 to move forward together, and the tooth tips of the active bevel teeth 511 again press against the tooth tips of the passive bevel teeth 521, and the internal disk 520 is pushed again to be separated from the ridge 101. When completely separated, the tooth tips of the passive bevel teeth 521 will slide to the tooth gap recess of the active bevel teeth 511 (such as Figure 8 As shown), the built-in disk 520 is rotated by an angle for the third time. At this time, the slide groove 501 of the built-in disk 520 is aligned with the ridge 101 again, and the plug-in rod 611 is no longer clamped with the connecting sleeve 522. Therefore, when the user stops applying force, the reset elastic member 530 causes the built-in disk 520, the inner push kit 510 and the battery cell housing 610 to retreat, and the built-in disk 520 and the inner push kit 510 return to the ridge 101 area, and the battery cell housing 610 can be separated from the inner push kit 510 and drawn out from the rod body 100;

[0054] During this disassembly, the rotation direction of the built-in disk 520 is consistent with the rotation direction during the above-mentioned installation period. The rotating built-in disk 520 will cause the safety switch 430 to rotate to ensure that the safety switch 430 is in the power-off position.

[0055] That is to say, when the battery cell assembly 600 is installed or removed, the internal disk 520 will rotate, thereby prompting the safety switch 430 to be turned to the power-off position, ensuring that the safety switch 430 can be automatically switched to the power-off position. In this way, the phenomenon of the fishing reel assembly 300 being accidentally started during the replacement of the battery cell can be eliminated, thereby avoiding safety accidents caused by accidental start-up and improving safety performance.

[0056] It should be noted that during installation, the battery cell housing 610 is close to the built-in disk 520, and the latch teeth 612 and the tooth groove 522 are just opposite (the tooth groove 522 provides a clearance space), and the plug-in rod 611 can be smoothly plugged into the connecting sleeve 522; then, the built-in disk 520 rotates an angle so that the latch teeth 612 and the tooth groove 522 are staggered with each other, and the latch teeth 612 cannot be separated from the connecting sleeve 522 due to the lack of clearance space. This makes the battery cell housing 610 and the built-in disk 520 mutually clamped, so that the battery cell housing 610 cannot be withdrawn from the rod body 100 after installation, thereby ensuring the stability of the electrical connection. During disassembly, the user needs to push the battery cell housing 610 inwards first, so that the built-in disk 520 rotates, and the latch teeth 612 and the tooth groove 522 are aligned again, so that the plug-in rod 611 can be separated from the connecting sleeve 522, and the battery cell housing 610 can be withdrawn from the rod body 100.

[0057] It can be seen that compared with the prior art, the electric fishing rod 10 with built-in battery cells of the present invention has the following beneficial effects:

[0058] First, by setting a double switch to achieve safe and convenient operation, the elastic switch 420 and the safety switch 430 are interrelated. After the safety switch 430 is switched to the power-on position, it only needs to press the elastic switch 420 to trigger, and release the elastic switch 420 to stop;

[0059] Secondly, when the battery cell assembly 600 is installed or removed, the safety switch 430 can be switched to the power-off position autonomously, thereby eliminating the phenomenon of the fishing reel assembly 300 being started by mistake and improving the safety performance;

[0060] Thirdly, after installation, the battery cell housing 610 cannot be withdrawn from the rod body 100, thereby ensuring the stability of the electrical connection; and the battery cell housing 610 will not suddenly slip and break during disassembly.

[0061] In this embodiment, a detachable tail cover 110 is provided at the end of the rod body 100 (eg Figure 2As shown in FIG. 1 , the tail cover 110 is connected to the rod body 100 by threads. When the battery cell assembly 600 is installed, the battery cell assembly 600 is inserted into the rod body 100 , and the tail cover 110 is held against the end surface of the battery cell housing 610 .

[0062] Preferably, the battery cell housing 610 is provided with an escape window 615 (such as Figure 5 As shown in FIG. 6 , several lithium batteries 620 can be assembled or disassembled through the avoidance window 615. When replacing the battery cell assembly 600, the user can choose to replace the entire battery cell assembly 600 (battery cell housing 610 and multiple lithium batteries 620) as needed, or only replace some of the lithium batteries 620.

[0063] In summary, the electric fishing rod 10 with built-in batteries of the present invention can realize autonomously turning off the switch during the battery disassembly and assembly process to avoid the accidental rotation of the fishing reel assembly 300, thereby preventing accidental injuries to users and improving operational safety.

[0064] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
