Description

Technical Field

[0001] This invention relates to the field of garden tools, and in particular to a dual-battery pack latch structure and a garden blower. Background Technology

[0002] Power tools are more environmentally friendly than engine-driven tools, leading to their widespread use. To facilitate portability, backpack blowers are now commonly used, allowing users to carry the equipment on their backs, thus reducing strain on their hands and alleviating fatigue.

[0003] Backpack blowers typically contain multiple batteries inside their housing. When in use, the housing is carried on a person's body via a carrying frame. Normally, the batteries are locked inside the housing. When charging, the batteries need to be unlocked and removed from the housing. However, the common method currently is to unlock one battery with a single press, or to unlock multiple batteries simultaneously with a single press. This method is not very flexible in terms of battery unlocking. Summary of the Invention

[0004] The purpose of at least one specific embodiment of the present invention is to overcome the defects of the prior art and provide a dual battery pack latch structure and a garden blower.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A dual-cell latch structure includes:

[0007] Battery mounting section;

[0008] The first battery pack and the second battery pack are inserted into the battery mounting section;

[0009] A latching assembly, which is mounted on a first battery pack, a second battery pack, or a battery mounting section, is capable of locking the mounting position of the first battery pack or the second battery pack on the battery mounting section;

[0010] The first unlocking component is installed on the first battery pack or battery mounting part and unlocks the locked state of the first battery pack through the latch assembly;

[0011] The second unlocking component is installed on the second battery pack or battery mounting part and unlocks the locked state of the second battery pack through the latch assembly;

[0012] When the first unlocking component is activated, the locking state of the first battery pack is unlocked independently; when the second unlocking component is activated, the locking state of the second battery pack is unlocked independently.

[0013] The first unlocking component and the second unlocking component are both located within the touchable area of ​​the human hand. A single touch action of the human hand can simultaneously activate the first unlocking component and the second unlocking component, thereby unlocking the locked state of the first battery pack and the second battery pack simultaneously.

[0014] Furthermore, the latch assembly includes:

[0015] Locking element;

[0016] The actuating element slides in conjunction with the locking element;

[0017] The first elastic element has one end in contact with the locking element and the other end in contact with the longitudinal support part inside the battery mounting part;

[0018] The second elastic member has one end in contact with the actuating member and the other end in contact with the transverse support portion inside the battery mounting portion;

[0019] When the trigger is activated, the trigger causes the locking member to be pushed out and lock the installation positions of the first battery pack and the second battery pack on the battery mounting part;

[0020] The trigger is configured as a first unlocking element and a second unlocking element.

[0021] Furthermore, the locking component includes a main body and a locking part, the main body having an insertion port, and the inner wall surface of the insertion port being an inclined surface;

[0022] The trigger includes an actuating part and an insertion part, and the side of the insertion part is provided with a pressing bevel;

[0023] When the trigger and the locking parts are engaged, the insertion part is inserted into the insertion port, and the pressing slope slides against the inner wall of the insertion port.

[0024] The sides of the first and second battery packs are provided with locking slots corresponding to the locking parts.

[0025] Furthermore, when the first battery pack and the second battery pack are inserted into the battery mounting part, the locking part extends into the locking slot to lock the mounting position of the first battery pack and the second battery pack on the battery mounting part.

[0026] When the insertion part is pressed downward, the pressing slope can press the inner wall of the insertion port, causing the locking part to exit from the locking groove, thereby unlocking the locking state of the first battery pack and the second battery pack.

[0027] Furthermore, an assist component is installed at the bottom of the battery mounting section, which is adapted to apply an upward lifting force to the first and second battery packs after they are unlocked.

[0028] Furthermore, the supporting components include:

[0029] The assist arm is hinged to the battery mounting section via a pin.

[0030] The power assist spring has one end connected to the battery mounting part and the other end connected to the end of the power assist arm.

[0031] The assist arm includes a connecting end and an assist lifting end, wherein the connecting end is connected to the assist spring, and the assist lifting end is close to the bottom of the first battery pack and the second battery pack.

[0032] Furthermore, after the first battery pack and the second battery pack are inserted into the battery mounting part, the first battery pack and the second battery pack exert pressure on the assist lifting end by their own weight, the assist arm rotates around the pin shaft, and the connecting end of the assist arm squeezes the assist spring.

[0033] Furthermore, when the first battery pack and the second battery pack are in the locked state, the locking part extends into the locking slot, and the lifting force applied by the lifting end of the assist arm to the first battery pack and the second battery pack causes the first battery pack and the second battery pack to have an upward stroke, thereby allowing the bottom of the locking slot to contact the bottom of the locking part.

[0034] Furthermore, the first battery pack and the second battery pack are provided with inclined handles, which are arranged opposite to each other and form a clearance space on the outside of the first unlocking member and the second unlocking member.

[0035] Furthermore, both the first and second battery packs are independently equipped with latching and assisting components.

[0036] The advantages of the wiring structure provided in this application compared to the prior art are as follows: when the first unlocking member of the latch structure is touched, the locking state of the first battery pack is unlocked independently; when the second unlocking member is touched, the locking state of the second battery pack is unlocked independently. Moreover, the first and second unlocking members are located within the touchable area of ​​the human hand, and a single touch action of the human hand can simultaneously touch the first and second unlocking members, thereby synchronously unlocking the locking states of the first and second battery packs. Whether the battery packs are unlocked individually or simultaneously, the unlocking can be completed with a single pressing action. After a single pressing unlocking action, one can choose to unlock a single battery pack or simultaneously unlock multiple battery packs, resulting in high flexibility in the unlocking operation.

[0037] Another technical solution adopted in this application is: providing a garden blower, comprising:

[0038] The aforementioned dual-battery pack latch structure;

[0039] The carrying frame is mounted on one side of the battery mounting section;

[0040] A blower assembly is located at the bottom of the battery mounting section. The blower assembly includes a drive motor and a fan. The first battery pack and the second battery pack are adapted to provide power to the drive motor so that the drive motor drives the fan to rotate and generate airflow through the main air duct of the blower assembly.

[0041] An air cooling channel is formed on the inner wall side of the backpack frame, with one end connected to the inner cavity of the first battery pack and the second battery pack, and the other end extending to connect to the main air duct of the blower assembly.

[0042] When the blower assembly receives power and rotates, a high-speed airflow is formed in the main air duct. The end of the air cooling channel connected to the main air duct forms a negative pressure inlet to guide the airflow from the inner cavities of the first and second battery packs into the main air duct through the air cooling channel.

[0043] Furthermore, the inner wall of the backpack extends outward to form a hollow groove. One side of the first battery pack and the second battery pack is provided with an air inlet corresponding to the hollow groove, and the other side of the first battery pack and the second battery pack is provided with an air outlet connected to the air cooling channel.

[0044] With the above technical solution, after installing the dual battery pack latch structure on the garden blower, the battery packs on the garden blower can be unlocked individually or simultaneously by pressing a single button. After pressing the button to unlock, one can choose to unlock a single battery pack or unlock multiple battery packs simultaneously, which provides high flexibility in the unlocking operation.

[0045] Furthermore, the garden blower utilizes an air cooling channel connected to the battery pack cavity and the main air duct of the blower assembly, which is set on the inner wall of the back frame. When the blower assembly is working, the high-speed airflow in the main air duct forms a negative pressure inlet at one end of the channel, which guides the airflow in the battery pack cavity into the main air duct, effectively removing the heat generated by the battery pack. This achieves efficient cooling of the battery pack, extending its service life and performance stability. Attached Figure Description

[0061] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] Example 1

[0063] Reference Figure 1 , Figure 2 , Figure 3A dual-battery pack latch structure 100 includes a battery mounting portion 10, a first battery pack 20a and a second battery pack 20b inserted into the battery mounting portion 10, and a latch assembly 30 mounted on the first battery pack 20a, the second battery pack 20b or the battery mounting portion 10. The latch assembly 30 is capable of locking the mounting positions of the first battery pack 20a and the second battery pack 20b on the battery mounting portion 10.

[0064] Furthermore, the dual battery pack latch structure 100 also includes a first unlocking member 40a, which is installed on the first battery pack 20a or the battery mounting part 10, and unlocks the locked state of the first battery pack 20a through the latch assembly 30.

[0065] The second unlocking member 40b is installed on the second battery pack 20b or the battery mounting part 10, and unlocks the locked state of the second battery pack 20b by means of the latch assembly 30.

[0066] In this embodiment, both the first unlocking member 40a and the second unlocking member 40b are installed on the battery mounting part 10. When the first unlocking member 40a is touched, the locking state of the first battery pack 20a is unlocked independently, and when the second unlocking member 40b is touched, the locking state of the second battery pack 20b is unlocked independently.

[0067] In this embodiment, the first unlocking member 40a and the second unlocking member 40b are both located within the touchable area of ​​the human hand. A touch action of the human hand can simultaneously activate the first unlocking member 40a and the second unlocking member 40b, thereby simultaneously unlocking the locked state of the first battery pack 20a and the second battery pack 20b.

[0068] The battery packs corresponding to this structure can be unlocked individually or simultaneously with two or more, all with a single press. After a press, you can choose to unlock a single battery pack or unlock multiple battery packs simultaneously, making the unlocking operation highly flexible.

[0069] The locking and unlocking process of the battery pack in this application will be described in detail below, taking into account the specific structure of the latch assembly.

[0070] Reference Figures 9 to 11The latch assembly 30 includes a locking member 301, an actuating member 302 that slides with the locking member 301, a first elastic member 303, and a second elastic member 304. One end of the first elastic member 303 abuts against the locking member 301, and the other end abuts against the longitudinal support portion 101 in the battery mounting portion 10. One end of the second elastic member 304 abuts against the actuating member 302, and the other end abuts against the transverse support portion 102 in the battery mounting portion 10. When the actuating member 302 is abutted, the actuating member 302 drives the locking member 301 to retract and unlock the mounting positions of the first battery pack 20a and the second battery pack 20b on the battery mounting portion 10.

[0071] The trigger 302 is configured as a first unlocking element 40a and a second unlocking element 40b.

[0072] Furthermore, specifically, the locking member 301 includes a main body 3011 and a locking part 3012. The main body 3011 is provided with an insertion port 3013, and the inner wall surface 3014 of the insertion port 3013 is an inclined surface. In addition, the sides of the first battery pack 20a and the second battery pack 20b are provided with locking grooves 20c corresponding to the locking part 3012.

[0073] The trigger 302 includes a trigger part 3021 and an insertion part 3022, and the side of the insertion part 3022 is provided with a pressing slope 3023;

[0074] When the trigger 302 and the locking member 301 are engaged, the insertion part 3022 is inserted into the insertion port 3013, and the pressing inclined surface 3023 slides with the inner wall surface 3014 of the insertion port 3013.

[0075] Specifically, refer to Figures 4 to 8 When the first battery pack 20a and the second battery pack 20b are inserted into the battery mounting part 10, the sides of the first battery pack 20a and the second battery pack 20b will first press the locking part 3012. After being pressed, the locking part 3012 will retract and compress the first elastic member 303. When the first battery pack 20a and the second battery pack 20b are installed in place, the locking part 3012 corresponds to the locking slot 20c. At this time, the reset first elastic member 303 pushes out the locking member 301, and the locking part 3012 extends into the locking slot 20c. At this time, the first battery pack 20a and the second battery pack 20b are locked on the battery mounting part 10.

[0076] When the first battery pack 20a and the second battery pack 20b need to be unlocked, the touch element 302 is pressed by hand. When the insertion part 3022 of the touch element 302 is pressed downward, the pressing slope 3023 can press the inner wall surface 3014 of the insertion port 3013, so that the locking part 3012 is disengaged from the locking slot 20c, and the locking state of the first battery pack 20a and the second battery pack 20b is unlocked. At this time, the first elastic element 303 is compressed.

[0077] In actual use, we found that after pressing the actuating element 302, although the locking part 3012 can retract from the locking slot 20c, after releasing the actuating element 302, the locking part 3012 will still extend into the locking slot 20c under the restoring force of the first elastic element 303. Therefore, when removing the first battery pack 20a and the second battery pack 20b, the hand needs to continue pressing the actuating element 302 without releasing it, which is inconvenient for removing the first battery pack 20a and the second battery pack 20b. Therefore, as a further improvement of this embodiment, an assistive component 50 is installed at the bottom of the battery mounting part 10. The assist component 50 is adapted to apply an upward lifting force to the unlocked first battery pack 20a and second battery pack 20b. The first battery pack 20a and second battery pack 20b will automatically spring upward, so that the locking slots 20c on the sides of the first battery pack 20a and second battery pack 20b are misaligned with the locking part 3012. After the first battery pack 20a and second battery pack 20b are unlocked, when the trigger 302 (first unlocking part 40a and second unlocking part 40b) is released by hand, the reset locking part 3012 cannot be inserted into the locking slot 20c, so that the first battery pack 20a and second battery pack 20b can be smoothly pulled out from the battery mounting part 10.

[0078] In addition, in this embodiment, the first battery pack 20a and the second battery pack 20b are provided with inclined handles 20d. The handles 20d are used to lift the first battery pack 20a and the second battery pack 20b out of the battery mounting part 10 after unlocking. The two handles 20d are arranged opposite to each other and form a clearance space on the outside of the first unlocking member 40a and the second unlocking member 40b. This clearance space makes it convenient for a person's palm to reach into the upper area of ​​the first unlocking member 40a and the second unlocking member 40b to touch the first unlocking member 40a and the second unlocking member 40b. In particular, when a person's palm needs to touch the first unlocking member 40a and the second unlocking member 40b simultaneously, the advantage of the clearance space is even more obvious.

[0079] Specifically, the assist component 50 includes an assist arm 502 that is hinged to the battery mounting part 10 via a pin 501, an assist spring 503 that is connected to the battery mounting part 10 at one end and to the assist arm 502 at the other end.

[0080] The assist arm 502 includes a connecting end 5021 and an assist lifting end 5022. The connecting end 5021 is connected to the assist spring 503, and the assist lifting end 5022 is close to the bottom of the first battery pack 20a and the second battery pack 20b.

[0081] After the first battery pack 20a and the second battery pack 20b are inserted into the battery mounting part 10, the first battery pack 20a and the second battery pack 20b exert pressure on the assist lifting end 5022 by their own weight. The assist arm 502 rotates around the pin 501, and the connecting end 5021 of the assist arm 502 compresses the assist spring 503. At this time, the first battery pack 20a and the second battery pack 20b are in a locked state, and at the same time, the assist lifting end 5022 is in a state of energy storage and compression. When battery pack 20a and battery pack 20b are locked, the locking part 3012 extends into the locking slot 20c. The lifting force applied by the lifting end 5022 to the first battery pack 20a and battery pack 20b allows the first battery pack 20a and battery pack 20b to have a slight upward stroke H, so that the bottom of the locking slot 20c is in close contact with the bottom of the locking part 3012. In this way, the first battery pack 20a and battery pack 20b will not become loose after being locked.

[0082] After the first battery pack 20a and the second battery pack 20b are unlocked, the limiting force of the locking part 3012 on the first battery pack 20a and the second battery pack 20b disappears. Under the action of the reset spring force of the assist spring 503, the assist arm 502 rotates around the pin 501. The assist lifting end 5022 applies an upward pushing force to the first battery pack 20a and the second battery pack 20b in a short time and lifts the first battery pack 20a and the second battery pack 20b upward, so that the locking groove 20c on the side of the first battery pack 20a and the second battery pack 20b is misaligned with the locking part 3012. When the first battery pack 20a and the second battery pack 20b are pulled out from the battery mounting part 10, the person can remove their hand from the trigger 302 (first unlocking part 40a and second unlocking part 40b), and the battery packs are easy to pull out.

[0083] In addition, in some embodiments, the first battery pack 20a and the second battery pack 20b are each independently equipped with a latch assembly 30 and an assist assembly 50. The first battery pack 20a and the second battery pack 20b can be locked and unlocked independently. Moreover, the first unlocking member 40a and the second unlocking member 40b are located within the touchable area of ​​the human hand. Specifically, the first unlocking member 40a and the second unlocking member 40b can be arranged adjacent to each other on the battery mounting part 10. In this way, a person's finger can press the first unlocking member 40a and the second unlocking member 40b simultaneously with a pressing action, thereby achieving the purpose of simultaneously unlocking the first battery pack 20a and the second battery pack 20b with a single pressing action.

[0084] Example 2

[0085] Reference Figure 12 , Figure 13 , Figure 14A garden blower 200 includes the dual battery pack latch structure 100 in the above embodiment, a carrying frame 210 installed on one side of the battery mounting part 10, and a blower assembly 300 provided at the bottom of the battery mounting part 10, wherein the blower assembly 300 includes a drive motor 310 and a fan 320.

[0086] The first battery pack 20a and the second battery pack 20b are used to provide power to the drive motor 310, so that the drive motor 310 drives the fan 320 to rotate and generate airflow through the main air duct 330 of the blower assembly 300.

[0087] In addition, in this embodiment, the garden blower 200 has an air cooling channel 400, which is formed on the inner wall side of the back frame 210. One end is connected to the inner cavity of the first battery pack 20a and the second battery pack 20b, and the other end extends to be connected to the main air duct 330 of the blower assembly.

[0088] When the blower assembly 300 is rotating under power, a high-speed airflow is formed in the main air duct 330. The end of the air cooling channel 400 connected to the main air duct 330 forms a negative pressure inlet 410, so as to guide the airflow in the inner cavity of the first battery pack 20a and the second battery pack 20b through the air cooling channel 400 to the main air duct 330.

[0089] Furthermore, the inner wall of the carrying frame 210 extends outward to form a hollow groove 220. One side of the first battery pack 20a and the second battery pack 20b is provided with an air inlet 420 corresponding to the hollow groove 220, and the other side of the first battery pack 20a and the second battery pack 20b is provided with an air outlet 430 communicating with the air cooling channel 400. The battery mounting part 10 is provided with a guide port 103 corresponding to the air outlet 430.

[0090] When the blower assembly 300 is rotating under power, a negative pressure is formed inside the main air duct 330. External airflow enters the inner cavity of the first battery pack 20a and the second battery pack 20b through the air inlet 420, and flows into the air cooling channel 400 through the air outlet 430 and the guide port 103 in sequence. Then, it enters the main air duct 330 through the negative pressure inlet 410 at the end of the air cooling channel 400, and is discharged from the end of the main air duct 330. During the airflow process, the airflow entering the main air duct 330 can carry away the heat in the inner cavity of the first battery pack 20a and the second battery pack 20b, and play a role in heat dissipation for the first battery pack 20a and the second battery pack 20b.

[0091] In summary, after the dual battery pack latch structure 100 is installed on the garden blower 200, the battery packs on the garden blower 200 can be unlocked by a single press action, whether unlocking one or more battery packs simultaneously. After a single press unlock action, one can choose to unlock a single battery pack or unlock multiple battery packs simultaneously, which provides high flexibility in the unlocking operation.

[0092] Furthermore, the garden blower 200 has an air cooling channel 400 connected to the battery pack cavity and the main air duct 330 of the blower assembly 300 by setting an air cooling channel 400 on the inner wall side of the back frame 210. When the blower assembly 300 is working, the high-speed airflow in the main air duct 330 forms a negative pressure inlet 410 at one end of the channel, which guides the airflow in the battery pack cavity into the main air duct 330, effectively removing the heat generated by the battery pack, achieving efficient cooling of the battery pack, and extending the service life and performance stability of the battery pack.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
