[0002] In handheld power tools, the battery pack accounts for a large proportion of the overall weight, placing a significant burden on the user's upper limbs. Existing backpack-style battery packs allow users to carry the battery pack on their back like a backpack, shifting the weight of the battery pack to the user's back and alleviating upper limb fatigue. However, with the battery pack on the back, it is inconvenient for a single person to change the battery without removing the battery pack carrying mechanism.

[0053] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0054] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0055] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0056] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0057] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0058] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0059] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0060] This embodiment provides a wearable power supply device, such as Figure 1 As shown, the wearable power supply device includes wearable equipment 10, a battery pack 50, a battery pack coupling 40, and a power cord 60. The wearable equipment 10 includes a waist belt 11 for wear by a user. The battery pack coupling 40 is connected to the wearable equipment 10, and the battery pack 50 is detachably coupled to the battery pack coupling 40. The waist belt 11 ensures that the battery pack coupling 40 and the battery pack 50 are supported at least around the user's waist. The battery pack 50 has a battery power output interface for outputting electrical energy. One end of the power cord 60 is connected to the battery power output interface, and the other end is used to connect to the power device. When the battery pack 50 is low on power, it can be removed and replaced with a new one, allowing continuous use of the power device. Optionally, the power device can be a handheld power tool. By securing the waist belt 11 around the user's waist, the weight of the battery pack 50 is transferred to the waist, thereby reducing the burden on the user's upper limbs.

[0061] In this embodiment, the battery pack 50 being detachably coupled to the battery pack coupling portion 40 means that when the battery pack 50 is installed on the battery pack coupling portion 40, the battery pack coupling portion 40 mechanically supports the battery pack 50, and the battery power output interface of the battery pack 50 is connected to the power line 60. The specific structure of the battery pack 50 and the battery pack coupling portion 40 can be any of the existing technologies, and is not specifically limited here.

[0062] In some embodiments, the statement that the battery pack 50 is detachably attached to the battery pack joint 40 simply means that the battery pack joint 40 mechanically supports the battery pack 50. In this embodiment, the power cable 60 can be manually plugged into the battery pack 50 to achieve electrical connection.

[0063] To facilitate users in changing the battery pack 50 without removing the wearable equipment 10, such as Figures 1-4As shown, the wearable power supply device also includes an operating mechanism 30, which is connected to the battery pack coupling 40. The operating mechanism 30 is used to change the position of the battery pack coupling 40. Specifically, when the wearable power supply device is in working condition, the operating mechanism 30 controls at least a portion of the battery pack coupling 40 to be positioned behind the user, preventing the battery pack 50 and the battery pack coupling 40 from obstructing the user's work; when the wearable power supply device is not in working condition, the operating mechanism 30 can control at least a portion of the battery pack coupling 40 to be positioned beside or in front of the user. Thus, the user can conveniently and quickly change the battery pack 50 without removing the wearable equipment 10, resulting in simple operation and a good user experience.

[0064] In other words, the operating mechanism 30 is used to change the orientation relationship between the battery pack 50 and the battery pack joint 40. Specifically, as... Figures 2-4 As shown, when the wearable power supply device is in working condition, the battery pack 50 is located behind the battery pack joint 40, thereby preventing the battery pack 50 and the battery pack joint 40 from obstructing the user's work; when the wearable power supply device is not in working condition, the battery pack 50 is located in front of the battery pack joint 40, thereby facilitating the user to replace the battery pack 50.

[0065] It should be noted that the working state of the wearable power supply device in this embodiment does not only refer to the discharging state of the battery pack 50. As long as the battery pack connection part 40 is behind the user, it is in the working state of the wearable power supply device. As long as the battery pack connection part 40 is beside or in front of the user, it is in the non-working state of the wearable power supply device.

[0066] like Figure 1 and Figure 2 As shown, when the wearable power supply device is in operation, the battery pack joint 40 is in a state of close contact with the waist belt 11, thereby bringing the center of gravity of the battery pack 50 closer to the user, reducing the burden on the user and improving the user experience. Figure 3 and Figure 4 As shown, when the wearable power supply device is in a non-working state, that is, when at least part of the battery pack connection 40 is located to the side or in front of the user, the battery pack connection 40 is away from the waist belt 11. This not only allows the battery pack connection 40 to move the battery pack 50 closer to the user's front or side, but also leaves enough operating space to improve the convenience of replacing the battery pack 50.

[0067] In this embodiment, as Figure 1 , Figure 5 and Figure 6As shown, the wearable power supply device also includes a support base 20, which is mounted on the waist belt 11. The operating mechanism 30 is connected to the support base 20. That is, the battery pack connection portion 40 is connected to the support base 20 via the operating mechanism 30, and thus to the waist belt 11. The support base 20 facilitates the installation of the battery pack connection portion 40. In some embodiments, the support base 20 is fixedly connected to the waist belt 11. In some embodiments, the support base 20 can slide relative to the waist belt 11, allowing the user to adjust the support base 20 and the battery pack connection portion 40 to a comfortable position, and also improving the convenience of battery pack replacement for users of different body types.

[0068] Optionally, the wearable power supply device also includes a spacer 14, which is connected to the waist belt 11 and located between the support base 20 and the user, preventing direct contact between the support base 20 and the user and reducing wear and tear on the user's clothing. Optionally, the support base 20 can be directly connected to the waist belt 11, or it can be connected to the waist belt 11 by connecting to the spacer 14. Optionally, the support base 20 can be connected to the waist belt 11 or the spacer 14 by means of screw fastening or other methods.

[0069] In this embodiment, as Figures 4-6 As shown, the support base 20 includes a support body 21 and an extension arm 22. The support body 21 is connected to the waist belt 11. One end of the extension arm 22 is connected to the support body 21, and the other end extends from behind the user towards the user's side. The operating mechanism 30 is connected to the other end of the extension arm 22. By setting the extension arm 22, the operating mechanism 30 can be placed in a position easily accessible to the user, improving the convenience of operating the operating mechanism 30. The support body 21 is located as far behind the user as possible. Optionally, the support body 21 and the extension arm 22 are integrally formed and constructed as a cavity structure. This cavity structure not only reduces weight but also allows for cable routing, facilitating the connection between the power cord 60 and the battery output interface of the battery pack 50. The specific connection method is described below.

[0070] like Figures 3-5As shown, the battery pack coupling 40 includes a coupling body 41 and a rotating arm 42. The battery pack 50 is detachably coupled to the battery pack coupling 40. One end of the rotating arm 42 is connected to the coupling body 41, and the other end of the rotating arm 42 can rotate relative to the support base 20. By setting the rotating arm 42, the rotation range of the battery pack 50 is increased. Thus, when the wearable power supply device is not in operation, the battery pack 50 is closer to the user's front, improving the convenience of battery pack 50 replacement. When the wearable power supply device is in operation, the battery pack 50 is as close as possible to the user's rear. Optionally, the rotating arm 42 can be integrally formed with the shell structure of the coupling body 41, and the shell of the coupling body 41 and the rotating arm 42 are constructed as a cavity structure. This cavity structure not only reduces weight but also allows for cable routing, facilitating the connection between the power cord 60 and the battery power output interface of the battery pack 50. The specific connection method is described below.

[0071] In this embodiment, the end of the extension arm 22 away from the support body 21 forms a first pivot portion 221, and the end of the rotating arm 42 away from the connecting body 41 forms a second pivot portion 421. The first pivot portion 221 and the second pivot portion 421 are pivotally connected, and the pivot axis extends in the vertical direction or nearly vertical direction. The battery pack connecting portion 40 can rotate relative to the support base 20 around the pivot axis.

[0072] Specifically, the first pivot 221 and the second pivot 421 are vertically connected and mutually restrained in the vertical direction. The inner cavity of the first pivot 221 is connected to the inner cavity of the second pivot 421. The power line 60 is partially fixed on the support body 21, and its end passes through the inner cavity of the support body 21, the inner cavity of the extension arm 22 (including the inner cavity of the first pivot 221), and then enters the inner cavity of the rotating arm 42 (including the inner cavity of the second pivot 421) and the inner cavity of the connecting body 41, and connects with the conductive contact on the connecting body 41. When the battery pack 50 is connected to the battery pack connecting part 40, the battery power output interface of the battery pack 50 contacts the conductive contact, thereby realizing the conduction with the power line 60. By housing the power cord 60 within the support base 20 and the battery pack junction 40, the wearable power supply device is not only more aesthetically pleasing, but also prevents the portion of the power cord 60 outside the support base 20 from moving when the battery pack junction 40 is switched, thus avoiding the problem of the power cord 60 becoming tangled when replacing the battery pack 50.

[0073] In this embodiment, the operating mechanism 30 is a rotating mechanism. The operating mechanism 30 rotates the battery pack coupling part 40 to switch the position of the battery pack coupling part 40 relative to the user (located behind the user, to the side of the user, or in front of the user). In other words, the operating mechanism 30 rotates the battery pack coupling part 40 to change the orientation relationship between the battery pack 50 and the battery pack coupling part 40.

[0074] like Figure 5 and Figure 6 As shown, the operating mechanism 30 includes an operating switch 31. When at least a portion of the battery pack connection 40 is behind the user, the operating switch 31 is in a first state; when at least a portion of the battery pack connection 40 is beside or in front of the user, the operating switch 31 is in a second state. In this embodiment, the operating switch 31 can be a button. In other embodiments, the operating switch 31 may be a push-pull structure or other structure operated by the user to switch positions.

[0075] When the operating switch 31 is in the first state (such as the initial position), the operating mechanism 30 locks the positions of the support base 20 and the battery pack coupling 40, keeping the battery pack coupling 40 in a position behind the user. When the user operates the operating switch 31 to the second state (such as the pressed-down position), the operating mechanism 30 unlocks the support base 20 and the battery pack coupling 40, allowing the battery pack coupling 40 to rotate. Furthermore, while unlocking the support base 20 and the battery pack coupling 40, the operating mechanism 30 can also automatically drive the battery pack coupling 40 to rotate from a position behind the user to a position at least partially beside or in front of the user, further improving the convenience of replacing the battery pack 50. Furthermore, when the user rotates the battery pack coupling 40 back to the position behind the user, the operating mechanism 30 can automatically lock the positions of the support base 20 and the battery pack.

[0076] In some embodiments, the operation button slides vertically with the second pivot 421. The operation mechanism 30 also includes a locking member connected to the operation switch 31. The locking member has a first concave-convex structure on its circumferential surface, a second concave-convex structure on the circumferential surface of the inner cavity of the first pivot 221, and a third concave-convex structure on the circumferential surface of the inner cavity of the second pivot 421. When the battery pack connection 40 is behind the user, the third and second concave-convex structures are aligned vertically. When the operation switch 31 is in the first state, the upper and lower ends of the first concave-convex structure engage with the third and second concave-convex structures respectively, thereby locking the support 20 and the battery pack connection 40. When the operation switch 31 is pressed, the operation switch 31 causes the locking member to move downward and separate from the second pivot 421, thereby unlocking the support 20 and the battery pack connection 40. When the battery pack connection 40 rotates relative to the support 20, the third concave-convex structure and the first concave-convex structure are vertically misaligned, thus keeping the support 20 and the battery pack connection 40 in the unlocked state.

[0077] In some embodiments, the operating mechanism 30 further includes a first elastic element, one end of which is connected to a first pivot 221 and the other end to a second pivot 421. When at least part of the battery pack coupling 40 is located behind the user, the first elastic element is in a deformed state. When the locking member unlocks the support 20 and the battery pack coupling 40, the first elastic element drives the battery pack coupling 40 to move relative to the support 20, thereby causing the battery pack coupling 40 to automatically rotate to the front or side of the user. Optionally, the first elastic element can be a torsion spring.

[0078] In some embodiments, the operating mechanism 30 further includes a second elastic element configured to reset the operating switch 31 from a second state to a first state. Specifically, when the battery pack 50 is replaced and the user drives the battery pack coupling 40 to rotate behind the user, the third protrusion-contour structure on the second pivot 421 realigns with the first protrusion-contour structure on the locking member. The second elastic element drives the unlocking member upward along the pivot axis towards the second pivot 421, so that the unlocking member re-engages with the protrusion-contour structure of the second pivot 421 to re-lock the support 20 and the battery pack coupling 40.

[0079] It is understood that the above is only one possible implementation of the operating mechanism 30. In other embodiments, without departing from the inventive concept of this application, the operating structure can be any existing structure capable of locking and unlocking the support 20 and the battery pack joint 40.

[0080] like Figure 7 As shown, the wearable equipment 10 also includes a shoulder strap 12, which is connected to a waist belt 11. The cooperation between the shoulder strap 12 and the waist belt 11 prevents the battery pack 50 from slipping. In this embodiment, one end of the shoulder strap 12 is fixedly connected to the waist belt 11, while the other end can be fixed or unlocked by the user, improving overall ease of wear. In some embodiments, both ends of the shoulder strap 12 are detachably connected to the waist belt 11, allowing the user to choose whether or not to use the shoulder strap 12.

[0081] Optionally, the length of the shoulder strap 12 is adjustable, allowing the wearable power supply device to meet the needs of users with different body shapes. Optionally, the shoulder strap 12 is provided with an adjustment member 13, and the length of the shoulder strap 12 can be adjusted by adjusting the position of the adjustment member 13. Optionally, the adjustment member 13 can be a telescopic buckle.

[0082] In some embodiments, such as Figure 7 and Figure 8 As shown, part of the power cord 60 is connected to the shoulder strap 12. The shoulder strap 12 can guide the power cord 60, that is, the power cord 60 extends to the front of the user along the shoulder strap 12 to facilitate connection with electrical equipment.

[0083] In some embodiments, the power cord 60 includes a first power cord 61 and a second power cord 62, the length of which is adjustable. Therefore, when adjusting the length of the shoulder strap 12, the adjustable length of the first power cord 61 allows for adaptive adjustment of the overall length of the power cord 60, preventing it from being pulled and broken. In this embodiment, one end of the first power cord 61 is connected to the support base 20, and the other end is connected to one end of the second power cord 62, the other end of which is used to connect to the electrical device. Optionally, the first power cord 61 can be a spring cord.

[0084] like Figure 7 As shown, the first power cord 61 includes a portion connected to the adjusting member 13, which slides on the shoulder strap 12 to adjust the length of the first power cord 61. In other words, while adjusting the length of the shoulder strap 12 via the adjusting member 13, the first power cord 61 can be adjusted synchronously, improving the convenience of using the wearable power supply device. Optionally, the portion of the first power cord 61 connected to the adjusting member 13 can be a structure such as a sleeve.

[0085] In this embodiment, as Figure 1 and Figure 7 As shown, the adjusting member 13 is configured such that when the adjusting member 13 moves along the shoulder strap 12 toward the user's front, the length of the shoulder strap 12 increases, and at this time the adjusting member 13 pulls the first power cord 61 to lengthen.

[0086] In other embodiments, the adjusting member 13 can be a structure independent of the shoulder strap 12, that is, the adjusting member 13 is only used to adjust the length of the first power cord 61. In this case, the adjusting member 13 can specifically be a clip or other structure that facilitates position adjustment.

[0087] like Figure 7 As shown, the wearable power supply device also includes a fixing member 70 for detachably securing the second power cord 62 to the user's arm. The fixing member 70 guides the extension direction of the second power cord 60. When the user swings their arm to move the power device, the second power cord 62 moves synchronously with the user's arm and the power device, preventing the second power cord 62 from being pulled and becoming loose from the power device, or from drooping and severely interfering with the operation of the power device.

[0088] In this embodiment, the fastener 70 includes a mating part 71 and a limiting part 72, wherein the mating part 71 is used to fix it to the user's arm. Optionally, the mating part 71 can be a structure such as Velcro or a clip fixed to a nylon strap. The limiting part 72 is used to allow the second power cord 62 to slide against the fastener 70 with resistance, so that the position of the second power cord 62 can be adjusted as needed without unlimited free movement. Optionally, the limiting part 72 can be a sleeve structure formed by a nylon strap, through which the second power cord 62 passes.

[0089] To facilitate the fastener 70 being secured to the user's arm, the wearable power supply device also includes a mating part for the user to wear on their arm, with the fastener 70 engaging with the mating part. Optionally, the mating part can be a sleeve, strap, or other structure that can be slipped onto the user's arm, and the Velcro of the mating part 71 can be attached to the mating part.

[0090] In this embodiment, the separation force between the fixing member 70 and the mating member is greater than the weight of the electrical device. That is, the electrical device alone will not cause the fixing member 70 to detach from the user's arm, ensuring the reliability of the second power cord 62's fixation. The separation force between the fixing member 70 and the mating member is less than the total weight of the electrical device and the wearable power supply device. In the event of a dangerous situation, the user only needs to loosen the belt 11, and the fixing member 70 will automatically separate from the user's arm under the combined force of the electrical device and the wearable power supply device, improving the safety of the wearable power supply device.

[0091] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that the above embodiments do not limit this application in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this application.
