[0031] The following combination Figures 1 to 15 The saddle tube battery sliding contact electrode device of the present invention is further described in detail.

[0032] The saddle tube battery sliding contact electrode device comprises an electric bicycle middle tube 1 and a battery housing 2 with a built-in battery pack. The upper end of the middle tube has a notch 11, and a locking device 3 is arranged on the outer surface of the middle tube at the notch; the locking device has a tightening ring 31 and an eccentric handle 32; the battery housing has two parallel and spaced concave linear slide grooves 21, and the battery housing is movably arranged on the inner side of the middle tube in a sliding manner; a conductive slide 22 is built in along the slide groove, and an insulating slot body 23 is provided between the slide and the slide groove; the slide is respectively connected to the positive and negative electrodes of the battery pack. Electrode; the middle tube has two first through holes 12, which correspond to the opening position of the battery shell slide groove; it also has a discharge assembly 4 that is detachably arranged with the battery shell, and the discharge assembly includes two discharge plugs 41 and a base 42; the tail ends of the two discharge plugs are fixed to the base and connected in a conductive manner; when the eccentric handle is close to the middle tube, the front ends of the two discharge plugs are respectively inserted into and passed through the first through holes and then connected to the slide; when the eccentric handle is opened and away from the middle tube, the front ends of the two discharge plugs are separated from the slide.

[0033] Furthermore, the upper end of the middle tube 1 refers to the upper end of the middle tube of the electric bicycle when the electric bicycle is in a normal riding state or a parked state. Since the middle tubes in the drawings of this patent are placed horizontally or obliquely for the purpose of illustration, additional explanation is provided here.

[0034] like Figures 1 to 5 The first embodiment is shown. The locking device 3 has a pull rod 33 that passes through two lugs 310 of the tightening ring. The front end of the pull rod is connected to the hinge shaft 34 at the end of the eccentric handle. The axis of the hinge shaft is parallel to the direction of the slide slot, which refers to the linear track direction of the slide slot. The discharge assembly 4 is fixedly mounted on the inside of the eccentric handle. The tightening ring has two second through holes 311, which correspond to the positions of the two first through holes. When the eccentric handle 32 is rotated toward the center tube 1, the front ends of the two discharge plugs 41 are inserted into and pass through the second through holes 311 and the first through hole 12, and then connected to the slide 22, achieving conductive connection with the positive and negative electrodes of the battery pack 7.

[0035] like Figures 6 to 8 The second embodiment shown here features a locking device 3 with a pull rod 33 that passes through two lugs 310 of the clamping ring. Its front end is connected to a hinge 34 at the rear of the eccentric handle; the axis of the hinge is parallel to the direction of the slideway. The discharge assembly 4 is movably connected to the outside of the clamping ring 31 via a set screw 5. A spring 51 is positioned between the discharge assembly and the clamping ring, and is sleeved around the set screw.

[0036] When the eccentric handle 32 is open, the discharge assembly 4 naturally rises under the thrust of the spring 51, and the front ends of the two discharge tabs 41 separate from the slide 22. When the eccentric handle 32 is rotated toward the center tube 1, the inner side of the eccentric handle 32 presses against the outer surface of the base 42, forcing the front ends of the two discharge tabs 41 into contact with the slide 22. This establishes a conductive connection between the positive and negative electrodes of the battery pack 7. Furthermore, a protrusion 321 is provided on the inner side of the eccentric handle 32. When the eccentric handle 32 is rotated toward the center tube 1, the protrusion 321 presses against the outer surface of the base 42, achieving a more stable connection.

[0037] like Figures 9 to 11 The third embodiment is shown. An articulated shaft 35 passes through the two lugs 310 of the tightening ring, and the rear end of the eccentric handle 32 is hingedly connected to the articulated shaft 35. The axis of the articulated shaft is perpendicular to the direction of the slideway, which refers to the linear track of the slideway. The discharge assembly 4 is fixedly mounted on the inside of the eccentric handle. When the eccentric handle 32 is rotated toward the center tube 1, the front ends of the two discharge plugs 41 pass through the first through-hole 12 of the center tube and connect to the slide 22, establishing electrical connection with the positive and negative electrodes of the battery pack 7.

[0038] like Figures 12 to 14 The fourth embodiment is shown. A hinge shaft 35 passes through two lugs 310 of the tightening ring, and the tail of the eccentric handle is hingedly connected to the hinge shaft. The axis of the hinge shaft 35 is perpendicular to the direction of the slideway. The discharge assembly is movably connected to the outer side of the central tube via a set screw 5. A spring 51 is installed between the discharge assembly and the tightening ring, and the spring is mounted on the set screw.

[0039] When the eccentric handle 32 is open, the discharge assembly 4 naturally rises under the thrust of the spring 51, and the front ends of the two discharge tabs 41 separate from the slide 22. When the eccentric handle 32 is rotated toward the center tube 1, the inner side of the eccentric handle 32 presses against the outer surface of the base 42, forcing the front ends of the two discharge tabs 41 into contact with the slide 22. This establishes a conductive connection between the positive and negative electrodes of the battery pack 7. Furthermore, a protrusion 321 is provided on the inner side of the eccentric handle 32. When the eccentric handle 32 is rotated toward the center tube 1, the protrusion 321 presses against the outer surface of the base 42, achieving a more stable connection.

[0040] Furthermore, a bushing 6 is provided between the center tube 1 and the battery housing 2. The bushing has a slit on its upper portion that corresponds to the notch 11 in the center tube. The bushing also has two third through holes that correspond to the two first through holes 12 in the center tube. The bushing 6 is designed to reduce wear between the center tube 1 and the battery housing 2, allowing for smoother extraction of the battery housing 2 from the center tube 1. Furthermore, it effectively reduces vibration of the battery housing while the e-bike is in motion.

[0041] Furthermore, two contact electrodes 24 are provided at the end of the slide slot 21 of the battery housing, and the contact electrodes are respectively connected to the two slides in a conductive manner.

[0042] Furthermore, the tail ends of the two discharge plugs 41 are connected in a conductive manner, which means that a wire or a conductive sheet is built into the base 42 , and the wire or the conductive sheet connects the tail ends of the two discharge plugs 41 .

[0043] like Figure 15 As shown, the sliding plate 22 and the insulating slot 23 are both long and narrow. The insulating slot 23 covers the outer periphery of the sliding plate 22 in a wrapping manner, with a slit 231 provided only on one side of the sliding plate opening 221. The insulating slot 23 is an elastic member, such as a silicone member. The slit 231 is normally closed, effectively preventing dust, water droplets, etc. from entering and corroding the sliding plate 22. When subjected to external force, the slit 231 opens.

[0044] Furthermore, the center tube 1 is a tube with a teardrop-shaped cross-section. The cross-sectional shapes of the battery housing 2 and bushing 6 match the cross-sectional shape of the center tube 1. The inner shape of the tightening ring 31 matches and fits the outer surface of the center tube 1. The battery pack 7 is arranged in multiple layers in an alternating pattern within the center tube 1 to maximize space utilization.

[0045] Furthermore, the battery housing 2 is a seat rod, that is, one end of the battery housing is provided with a saddle connected to the electric bicycle.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
