Detailed Description
The invention is described in detail below with reference to the figures and the embodiments.
As shown in fig. 1 to 4, the backpack power supply apparatus 100 includes a battery pack 10, a wearing device 20, and a main body 30.
The battery pack 10 is used to output electric power. The main body 30 carries the battery pack 10. The battery pack 10 is detachably connected to the main body 30. As an alternative embodiment, the battery pack 10 may also be fixed to the main body 30 as a non-detachable portion.
The wearing apparatus 20 is connected to the main body 30. The wearing device 20 is worn by a user to bear the main body 30. The wearing equipment 20 includes a harness 21. Both ends of the back band 21 are connected to the main body 30. When the user wears the harness 21, both ends of the harness 21 apply a force to the main body 30. Specifically, the shoulder strap 21 includes an upper end connected to an upper portion of the main body 30 and a lower end connected to a lower portion of the main body 30. When the user wears the wearing equipment 20, the upper end of the harness 21 applies a force F1 to the main body 30.
The main body 30 defines up and down, front and back, and left and right when the user wears the wearing device 20, that is, when the backpack power supply apparatus 100 is used by the user in an operating state. The vertical direction is the height direction. The user's back is positioned in front of the main body 30. The battery pack 10 is coupled to the rear of the main body 30. A handle 321 is formed at the upper portion of the main body 30. The handle 321 is used for the user to carry the backpack power supply device 100.
As shown in fig. 3 and 7, a back plate face 323 is formed at the front of the main body 30. The back plate surface 323 extends in the height direction. Specifically, the back plate face 323 is planar.
The body 30 defines a plane of symmetry 301. The body 30 is at least partially symmetrical about a plane of symmetry 301. Specifically, the main body 30 is at least partially symmetrical in the left-right direction.
An angle β between a projection of a direction of the force F1 applied to the main body 30 by the upper end of the back belt 21 on the symmetry plane 301 and the height direction is not less than 30 degrees and not more than 50 degrees.
The specific direction of the force F1 applied to the main body 30 by the upper end of the harness 21 makes it possible to save labor when the user wears the harness 20, and to prevent the main body 30 from falling backward. The main body 30 is kept upright and comfortable to wear.
In the projection of the plane of symmetry 301, the center of gravity G1 of the battery pack 10 and the body 30 as a whole is located between the line 302 where the force F1 is located and the back plate plane 323. The straight line 302 where the force F1 is located passes through the point of action and is parallel to the direction of the force F1.
The position of the center of gravity G1 of the battery pack 10 and the main body 30 also makes the main body 30 less prone to toppling backwards when the user is wearing the device 20, resulting in discomfort of the user due to the main body 30 exerting a forward force F1 on the user's back.
When the user extends the length of the harness 21, the angle β between the projection of the direction of the biasing force F1 exerted by the upper end of the harness 21 on the main body 30 on the plane of symmetry 301 and the height direction becomes smaller, and the center of gravity G1 of the entire battery pack 10 and the main body 30 is closer to the straight line 302 where the biasing force F1 exerted by the upper end of the harness 21 on the main body 30 is located. The user wears the wearing device 20 more laborsavingly.
In the projection of the plane of symmetry 301, the center of gravity G2 of the battery pack 10 is located between the line 302 where the force F1 is located and the backplate surface 323. The ratio of the distance L1 from the center of gravity G1 of the entire battery pack 10 and the main body 30 to the back plate surface 323 to the dimension L2 of the entire battery pack 10 and the main body 30 in the front-rear direction is 0 or more and 0.85 or less. Further, the ratio of the distance L1 from the center of gravity G1 of the entire battery pack 10 and the main body 30 to the back plate surface 323 to the dimension L2 in the front-rear direction of the entire battery pack 10 and the main body 30 is 0 or more and 0.75 or less.
As shown in fig. 5 to 7, the wearing apparatus 20 includes a back pad 22 for contacting the back of the user. The back pad 22 is slidably connected to the main body 30 in the height direction.
The back pad 22 is capable of moving relative to the main body 30 against the back of the user as the user bends over. Has high comfort.
The back pad 22 is fixed to the back belt 21. When different lengths of the back belt 21 are used, the direction of the acting force F1 exerted by the back belt 21 on the main body 30 is different, and the height of the back pad 22 varies with the angle β of the back belt 21, so that the user can wear the back pad comfortably.
As a specific embodiment, the wearing gear 20 further includes a shoulder pad 23. The shoulder pad 23 is fixed to the back pad 22. The shoulder pad 23 at least partially overlaps the shoulder strap 21. The shoulder pad 23 is fixed to the shoulder strap 21. The shoulder pad 23 and the back pad 22 may be integrated.
As an alternative embodiment, the shoulder pad 23 is constructed integrally with the back band 21.
As another alternative embodiment, the shoulder pad 23 is secured to the back strap 21 as a separate piece. I.e. the shoulder pad 23 and the back pad 22 are not integral.
The harness 20 further includes a slider 24. The slider 24 is slidably connected to the body 30. The back pad 22 is fixed to the slider 24. The slider 24 is made of a plastic material.
The slider 24 is formed with a projection 241. The main body 30 is formed with a guide groove 322. The protrusion 241 slides in the height direction within the guide groove 322.
The battery pack 10 is slidably coupled to the main body 30. The mounting direction of the battery pack 10 is parallel to the sliding direction of the back pad 22 with respect to the main body 30. When the user wears the wearing apparatus 20, the user mounts the battery pack 10 in a downward direction, and the back pad 22 slides upward as the main body 30 moves downward due to the friction between the battery pack 10 and the main body 30 and the gravity of the battery pack 10. The relative movement of the back pad 22 and the body 30 does not cause the back pad 22 to exert a downward force F1 on the user's back for comfort. And as the body 30 moves downwards, the projection of the direction of the force F1 in the plane of symmetry 301 makes a smaller angle β with the height direction. The user wears more laborsavingly.
The slider 24 is detachably connected to the main body 30.
As shown in fig. 2, 3, and 8 to 10, the projection of the main body 30 on the symmetry plane 301 is L-shaped. The battery pack 10 is positioned in the included angle region formed by the L-shape.
Specifically, the main body 30 includes a base 31 and a guide 32. The mount 31 serves to support the main body 30 so that the main body 30 can be laid on the ground. The guide portion 32 is used to guide the guide portion 32 of the battery pack 10 sliding in the height direction with respect to the main body 30. The base 31 and the guide 32 are L-shaped.
The guide portion 32 is projected with two side stoppers 33 toward the battery pack 10. The guide portion 32 projects rearward with two side stoppers 33. The side stoppers 33 are long strips extending in the height direction. The two side stops 33 are located on both sides of the battery pack 10.
As shown in fig. 4, the battery pack 10 is provided with a battery electrical output interface 11 and a plurality of cell units. The battery cell unit is used for storing electric energy. The battery electrical output interface 11 is used to output electrical energy.
As shown in fig. 4 and 7, the main body 30 is provided with an equipment electrical input interface 34 and an equipment electrical output interface 41. The equipment electrical input interface 34 is arranged to mate with the battery electrical output interface 11. When the battery pack 10 is coupled to the main body 30, the equipment electrical input interface 34 is electrically connected to the battery electrical output interface 11. The equipment electrical output interface 41 can be electrically connected to the equipment electrical input interface 34.
The main body 30 includes a main body cabinet 37. The battery pack 10 is detachably coupled to the main body housing 37.
In one embodiment, the main body 30 further includes a cable 40, and one end of the cable 40 is connected to the main body case 37. The other end of the cable 40 is provided with a device electrical output interface 41.

The terminal housing 42 defines a length direction and a width direction. The length direction and the width direction are perpendicular to the mounting direction of the equipment electrical output interface 41. A dimension L3 of the terminal housing 42 in the longitudinal direction is larger than a dimension L4 of the terminal housing 42 in the height direction. The electrode member 43 is disposed in the terminal housing 42. The two pole elements 43 are arranged in the longitudinal direction.
The ratio of the dimension L3 of the terminal housing 42 in the longitudinal direction to the dimension L4 of the terminal housing 42 in the height direction is 1.5 or more and 4 or less. The ratio of the dimension L3 of the terminal housing 42 in the longitudinal direction to the dimension L4 of the terminal housing 42 in the height direction is 2 or more and 3 or less. The dimension of the terminal housing 42 in the width direction is 15mm to 30 mm. The dimension L3 of the terminal housing 42 in the longitudinal direction is 40mm or more and 60mm or less
As shown in fig. 11-13, the main body 30 further includes a safety switch 48. The main body case 37 includes a first housing 371 and a second housing 372. The first and second housings 371 and 372 form the accommodation chamber 38. A safety switch 48 is disposed within the receiving cavity 38.
The safety switch 48 is electrically connected between the equipment electrical output interface 41 and the equipment electrical input interface 34. The safety switch 48 has a first state that renders the equipment electrical output interface 41 and the equipment electrical input interface 34 conductive and a second state that renders the equipment electrical output interface 41 and the equipment electrical input interface 34 non-conductive. The safety switch 48 is in a second state in fig. 12. The safety switch 48 is in a first state in fig. 13.
When the battery pack 10 is coupled to the main body 30, the safety switch 48 is in the first state; an electrical connection is made between the equipment electrical output interface 41 and the equipment electrical input interface 34. When the battery pack 10 is separated from the main body 30, the safety switch 48 is in the second state; the electrical connection between the equipment electrical output interface 41 and the equipment electrical input interface 34 is broken.
When the battery pack 10 is separated from the main body 30, the safety switch 48 disconnects the electrical connection between the equipment electrical output interface 41 and the equipment electrical output interface 41. When the equipment electrical output interface 41 is connected to the tool, electrical power from a power storage device, such as a capacitor, on the tool is transferred to the equipment electrical output interface 41 but not to the equipment electrical input interface 34. Preventing a user from contacting the exposed arming electrical input interface 34 to cause an electrical shock.
The body 30 further includes a wire 35 and a magnetic ring 36. The lead 35 is disposed in the accommodation chamber 38. The magnetic ring 36 is disposed in the receiving cavity 38. The wire 35 passes through the magnetic ring 36. The wires 35 electrically connect the cable wires 40 and the equipment electrical input interface 34, thereby electrically connecting the equipment electrical input interface 34 and the equipment electrical output interface 41. The safety switch 48 is connected to the wire 35.
The body 30 also includes a contact member 45 and a biasing member 44. The contact 45 is movably connected to the main body case 37. Specifically, the contact 45 is rotatably connected to the main body housing 37. The contact 45 is for contacting the battery pack 10. The contact 45 has a first position and a second position. When the battery pack 10 is coupled to the main body 30, the battery pack 10 presses the contact member 45 against the biasing member 44 to place the contact member 45 in the first position. When the battery pack 10 is separated from the main body 30, the biasing member 44 applies a force to the contact member 45 to move the contact member 45 to the second position.
The biasing member 44 applies a force to the contact member 45 to move it from the first position to the second position, thereby separating the battery pack 10 from the main body 30. The biasing member 44 and the contact member 45 function to assist the separation of the battery pack 10 from the main body 30.
As a specific embodiment, the biasing member 44 is a spring. The spring is disposed between the main body case 37 and the contact 45. In other embodiments, the biasing member 44 may be a spring, a magnetic member, or an electromagnet.
The body 30 also includes a locking member 46. The locking member 46 is coupled with the battery pack 10 to lock the position of the battery pack 10 when the battery pack 10 is coupled with the main body 30. When the locking member 46 is separated from the battery pack 10 by a user operation, the battery pack 10 is separated from the main body 30 by the biasing member 44.
Specifically, in fig. 13, when the contact 45 is in the first position, the safety switch 48 is in the first state when the contact 45 triggers the safety switch 48. In fig. 12, the safety switch 48 is in the second state when the contact 45 is in the second position.
Specifically, the main body 30 further includes a transmission member 47. One end of the transmission member 47 is in contact with the contact member 45, and the other end is in contact with an actuating reed or an actuating contact of the safety switch 48. The transmission member 47 is movably connected to the main body casing 37. The transmission member 47 is rotatably connected to the main body casing 37. The transmission member 47 is disposed in the accommodating chamber 38. When the user mounts the battery pack 10 such that the battery pack 10 is coupled to the main body housing 37, the contact 45 is driven by the battery pack 10 to move from the second position to the first position. The contact element 45 drives the transmission element 47 in rotation, and the transmission element 47 actuates the safety switch 48, so that the equipment electrical output interface 41 and the equipment electrical input interface 34 are switched on.
When the battery pack 10 is separated from the main body casing 37, the contact 45 and the transmission member 47 are reset, and the safety switch 48 disconnects the electrical connection between the equipment electrical output interface 41 and the equipment electrical input interface 34.
