[0032] A control module 21 is provided in the first shell 2; a containing cavity 22 is provided in the first shell 2; a heat-conducting seat 3 and a rotating shaft 4 are provided in the containing cavity 22; the heat-conducting seat 3 is fixedly provided in the containing cavity 22; a phase change cavity 31 is provided in the heat-conducting seat 3; one end of the rotating shaft 4 is rotatably provided in the containing cavity 22; the other end of the rotating shaft 4 is rotatably provided in the phase change cavity 31; phase change material is filled between the phase change cavity 31 and the other end of the rotating shaft 4; a locking arm 41 is provided in the middle of the rotating shaft 4; a heating element 32 is provided on the heat-conducting seat 3; the heating element 32 is electrically connected to the control module 21; a reset element 43 is provided between the rotating shaft 4 and the containing cavity 22.
[0033] Specifically, the electric bicycle charger with anti-theft function described in this embodiment, its control module 21 can be a single-chip microcomputer for receiving signals from the electric bicycle; its phase change material can be tin or rosin, etc. At room temperature or in the charging state, since the temperature has not reached the threshold, the phase change material is in a solid state; when the temperature exceeds the threshold, the phase change material is heated and melted to become liquid.
[0034] Specifically, when the electric bicycle is unlocked, the control module 21 can control the heating element 32 to generate heat according to the signal, and after the heat is transferred to the phase change material through the heat-conducting seat 3, the phase change material is heated and melted to become liquid. At this time, the rotating shaft 4 and the phase change cavity 31 of the heat-conducting seat 3 are flexibly connected, and the rotating shaft 4 can rotate normally, so that the locking arm 41 can be inserted into the locking piece 7;
[0035] When the power supply to the heating element 32 stops, the heating element 32 stops heating, and when it cools to a certain temperature, the phase change material solidifies into a solid state again, wherein a heat dissipation channel can be provided in the first shell 2 to accelerate the cooling of the thermal seat 3; after the phase change material solidifies into a solid state again, the rotating shaft 4 and the phase change cavity 31 of the thermal seat 3 are rigidly connected, and the rotating shaft 4 cannot rotate at this time, so that the locking arm 41 can be locked in the locking plate 7, thereby playing an anti-theft role.
[0036] In the electric bicycle charger with anti-theft function described in this embodiment, the body 11, the first and the connecting line 12 are an integrally formed structure, which further improves the anti-theft effect.
[0037] In the electric bicycle charger with anti-theft function described in this embodiment, the heating element 32 is a heating coil; the heating coil is wound outside the heat-conducting seat 3.
[0038] Specifically, the above arrangement can quickly heat the phase change material in the heat conducting seat 3 , so that the phase change material is melted by the heat and changes into a liquid state.
[0039] In the electric bicycle charger with anti-theft function described in this embodiment, a reset portion 44 is provided at one end of the rotating shaft 4; a fixed portion 45 is provided at the other end of the rotating shaft 4; the locking arm 41 is provided between the reset portion 44 and the fixed portion 45; the reset portion 44 is rotatably provided on the inner wall of the accommodating cavity 22; and the fixed portion 45 is rotatably provided in the phase change cavity 31. Specifically, the above arrangement makes the overall structure of the rotating shaft 4 stable and reliable.
[0040] In the electric bicycle charger with anti-theft function described in this embodiment, the outer wall of the fixing portion 45 is provided with a plurality of pits 46 along the circumferential direction. Specifically, through the above arrangement, the contact area between the phase change material and the fixing portion 45 in the solid state can be increased, so that the rotation shaft 4 and the phase change cavity 31 of the heat conducting seat 3 can be rigidly connected, and the rotation shaft 4 cannot be rotated.
[0041] In the electric bicycle charger with anti-theft function described in this embodiment, the reset member 43 is a torsion spring; one end of the torsion spring is arranged on the inner wall of the accommodating cavity 22; the other end of the torsion spring is arranged on the reset portion 44. Specifically, the above can facilitate the rotation of the shaft 4 and the locking arm 41 to reset, thereby locking with the locking plate 7.
[0042] In the electric bicycle charger with anti-theft function described in this embodiment, the first housing 2 is provided with a boss 5; the boss 5 is provided with a plug-in cavity 51; the plug-in cavity 51 is provided with a plug-in terminal 52; the plug-in cavity 51 is connected to the accommodating cavity 22 with a movable groove 53; the locking arm 41 passes through the movable groove 53 to form a locking block 42 in the plug-in cavity 51. In the electric bicycle charger with anti-theft function described in this embodiment, the electric bicycle charger with anti-theft function further includes a second housing 6; the second housing 6 is provided with a groove 61 that matches the boss 5; the second housing 6 is provided with a plug-in groove 62 that matches the plug-in terminal 52; the second housing 6 is provided with a locking piece 7 that matches the locking arm 41; the locking piece 7 is provided with a locking groove 71 that matches the locking block 42.
[0043] Specifically, the second housing 6 is an external socket, and through the above arrangement, the first housing 2 is connected to the second housing 6, so that the electric bicycle can be charged through the electric bicycle charger.
[0044] In the electric bicycle charger with anti-theft function described in this embodiment, the lock piece 7 is provided with a first inclined surface 72 at the top of the lock groove 71; the lock piece 7 is provided with a second inclined surface 73 at the top of the first inclined surface 72; the inclination direction of the first inclined surface 72 is opposite to the inclination direction of the second inclined surface 73. In the electric bicycle charger with anti-theft function described in this embodiment, the plug-in cavity 51 is provided with a pole needle; the second shell 6 is provided with an electrode sleeve 9 that cooperates with the pole needle; the pole needle is electrically connected to the control module 21. In the electric bicycle charger with anti-theft function described in this embodiment, the pole needle includes a contact portion 81 and a separation portion 82; the separation portion 82 is provided at the top of the contact portion 81; the radius of the separation portion 82 is smaller than the radius of the contact portion 81; after the first shell 2 and the second shell 6 are plugged in, the separation portion 82 is provided in the electrode sleeve 9.
[0045] Specifically, when the electric bicycle charger described in this embodiment is in use, when the boss 5 just contacts the groove 61, Figure 6 As shown, at this time, the contact portion 81 penetrates into the electrode sleeve 9 and contacts the electrode sleeve 9. When the electric bicycle is in the unlocked state, the control module 21 senses that the contact portion 81 is in contact with the electrode sleeve 9, thereby controlling the heating element 32 to generate heat. After the heat is transferred to the phase change material through the heat conductive seat 3, the phase change material is heated and melted to become liquid. At this time, the rotating shaft 4 and the phase change cavity 31 of the heat conductive seat 3 are flexibly connected, and the rotating shaft 4 can rotate normally.
[0046] Continue to press down the first housing 2 until the locking block 42 contacts the top of the second inclined surface 73. Continue to press down the first housing 2. Since the rotating shaft 4 and the phase change cavity 31 of the heat conducting seat 3 are flexibly connected, the locking block 42 can move downward along the second inclined surface 73 while the rotating shaft 4 rotates.
[0047] When the boss 5 is fully inserted into the groove 61, the locking block 42 moves past the bottom of the second inclined surface 73, and under the action of the torsion spring, the locking block 42 is locked in the locking groove 71, and at this time, the separation portion 82 penetrates into the electrode sleeve 9, and the radius of the separation portion 82 is small, so that the separation portion 82 is separated from the electrode sleeve 9, forming a Figure 7 The state shown; after the control module 21 senses that the separation portion 82 is separated from the electrode sleeve 9, when the power supply to the heating element 32 stops, the heating element 32 stops heating, and when it is cooled to a certain temperature, the phase change material solidifies into a solid state again, and the rotating shaft 4 and the phase change cavity 31 of the heat-conducting seat 3 are rigidly connected. At this time, the rotating shaft 4 cannot rotate, so that the locking block 42 can be locked in the locking groove 71, thereby playing an anti-theft role.
[0048] When the first housing 2 is plugged into the second housing 6 , as long as the user does not start the electric bicycle, the control module 21 will not start the heating element 32 for heating, thereby ensuring a rigid connection between the rotating shaft 4 and the phase change cavity 31 of the heat conducting seat 3 .
[0049] When it is necessary to separate the first shell 2 from the second shell 6, the electric bicycle is first started, and then the locking block 42 is moved upward. When the locking block 42 moves up to the bottom of the first inclined surface 72, the contact portion 81 re-inserts into the electrode sleeve 9 and contacts the electrode sleeve 9; after the control module 21 receives the signal, the heating element 32 is started again, so that the phase change material becomes liquid, so that the locking block 42 can move upward along the first inclined surface 72, thereby releasing the locking relationship between the locking block 42 and the locking groove 71.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
