Referring to fig. 2 and 3, the handle 2 has a storage state for folding and an operating state for carrying, the handle 2 can be switched between the storage state and the operating state, when the handle 2 is in the storage state, the handle 2 is stored in the notch 19, at this time, the space occupancy rate of the power supply device 100 is small, the overall appearance is attractive, when the handle 2 is in the operating state, the handle 2 is located outside the notch 19, the power supply device 100 is convenient to carry, and the operation is simple.

Referring to fig. 4, in the embodiment, the handle 2 is pivotally connected to the body 1 through the rotating shaft 7, and the rotating shaft 7 is located in the body 1 and can rotate relative to the body 1, so that the handle 2 can rotate relative to the body 1. Indeed, in other embodiments, the handle may also be telescopically movable relative to the body to enable the handle to be switched between the working state and the storage state. The connection mode of the handle 2 and the body 1 is not particularly limited, and is selected according to actual needs.

Handle 2 is U type structure, makes things convenient for the operator to grip, and the U type both ends of handle 2 are respectively through pivot 7 and fuselage 1 swing joint, increases the stability of being connected between handle 2 and the fuselage 1. Two grooves 15 are formed at the top end of the machine body 1, the two grooves 15 accommodate the U-shaped two ends of the handle 2, when the handle 2 is in an accommodating state, the top end of the handle 2 is approximately parallel to the plane where the display button 42 is located, the handle 2 does not occupy extra space, the structural layout of the power supply device 100 is reasonable, and space is saved.

Referring to fig. 5 to 8, the power supply device 100 further includes a locking mechanism 6, when the handle 2 is in the storage state and/or the working state, the locking mechanism 6 fixes the handle 2 and the main body 1 relatively, in this embodiment, when the handle 2 is in the storage state and the working state, the locking mechanism 6 can fix the handle 2 and the main body 1 relatively. The body 1 is provided with a housing groove 16, and the lock mechanism 6 is housed in the housing groove 16. In this embodiment, the locking mechanisms 6 are disposed outside the rotating shaft 7, the number of the locking mechanisms 6 may be one or two, the locking mechanisms 6 may also be disposed between the handle 2 and the rotating shaft 7, and the specific number and the setting state of the locking mechanisms 6 are not specifically limited herein and may be set according to actual needs.

The locking mechanism 6 includes a first abutting member 61 fixedly connected to the rotating shaft 7 and a second abutting member 62 disposed on the machine body 1, when the handle 2 is in the storage state, the first abutting member 61 abuts against the second abutting member 62 so that the second abutting member 62 is deformed to generate a force applied to the first abutting member 61, and the force applied to the first abutting member 61 by the second abutting member 62 is directed to the machine body 1, so that the handle 2 is in a relatively stable state. When the handle 2 is in the working state, the second abutting piece 62 limits the first abutting piece 61, so that the handle 2 is in a relatively stable state, specifically, the first abutting piece 61 and the second abutting piece 62 can contact each other or a gap exists between the first abutting piece 61 and the second abutting piece 62, and the range of the gap is 0-0.5 mm. The direction toward the body 1 is from the position of the handle 2 toward the position of the battery pack 3. In this embodiment, the handle 2, the rotating shaft 7 and the first abutting member 61 are integrally formed, so as to achieve the synchronous movement of the handle 2, the rotating shaft 7 and the first abutting member 61, but this is not limited specifically, and in other embodiments, the handle, the rotating shaft and the first abutting member may also be fixedly connected.

The first abutting member 61 is a limiting block, and has a first surface 611 and a second surface 612, in this embodiment, the first surface 611 is an arc surface, and the second surface 612 is a plane. The second abutting member 62 is an elastic piece engaged with the limiting block, in this embodiment, the elastic piece is a U-shaped elastic piece, two U-shaped ends of the elastic piece are fixed on the top wall of the accommodating groove 16, and a middle end of the elastic piece abuts against, contacts or separates from the limiting block.

The first abutting piece 61 and the handle 2 are arranged on two sides of the rotating shaft 7, and when the handle 2 rotates relative to the machine body 1 and is switched between the working state and the storage state, the handle 2 drives the first abutting piece 61 to rotate around the axis of the rotating shaft 7 through the rotating shaft 7, so that the first surface 611 or the second surface 612 rotates to the lower end surface of the second abutting piece 62. When the handle 2 moves from the storage state to the working state, the second surface 612 is located at a limit position where the second abutting member 62 limits the second surface 612, the second surface 612 contacts or has a gap with the second abutting member 62, the contact area between the second surface 612 and the second abutting member 62 is small or does not contact, the second abutting member 62 basically does not generate elastic deformation, the second abutting member 62 basically has no elastic force acting on the first abutting member 61, but the second abutting member 62 abuts or is close to the first abutting member 61, so that the first abutting member 61 is limited, the rotation of the handle 2 is limited, and the handle 2 is ensured to be in a stable state.

When the handle 2 is switched from the working state to the storage state, the first abutting member 61 rotates to enable the first surface 611 to rotate to abut against the second abutting member 62 at the abutting position, because the distance from the abutting position to the rotating shaft 7 is greater than the distance from the limiting position to the rotating shaft 7, the contact area between the first surface 611 and the second abutting member 62 is larger than that between the second surface 612 and the second abutting member 62, the second abutting member 62 is elastically deformed by the abutting of the first abutting member 61, the second abutting member 62 has an elastic force acting on the first abutting member 61, the elastic force applied on the first abutting member 61 by the second abutting member 62 faces the machine body 1, that is, the elastic force can be decomposed into a centripetal force passing through the axis of the first abutting member 61 and a tangential force tangent to the first surface 611, the second abutting member 62 applies an acting force to the first abutting member 61 towards the machine body 1, and the first abutting member 61 and the handle 2 are relatively fixed, thereby ensuring the stability of the handle 2 in the stored state. Indeed, in other embodiments, the structure of the locking mechanism 6 may also be other, for example, the first abutting member 61 is an elastic sheet, and the second abutting member 62 is a limiting block, which is not limited in this respect.

To sum up, the utility model provides a power supply unit, its handle can be for the fuselage motion, and the handle has the operating condition who is used for the folding state of accomodating and is used for carrying the getting, during the use, moves operating condition with the handle, makes things convenient for carrying of power supply unit to get, and easy operation when not using, moves the handle to the state of accomodating for the occupancy in power supply unit space is little and whole pleasing to the eye.
