Description

Technical Field

[0001] The present invention relates to the field of circuit protection, and more particularly to a battery vehicle charger. Background Art

[0002] Chargers can be divided into industrial frequency chargers and high frequency chargers according to the design circuit operating frequency. Industrial frequency chargers are designed based on traditional analog circuit principles, and the internal power components of the chargers are relatively large. Generally, there is a small amount of noise when the charger is running under a large load.

[0003] The Chinese patent with the authorization announcement number (CN205407300U) discloses an electric vehicle charger. The outer shells of electric vehicle chargers on the market are all rectangular plastic boxes. Because there is no fixing method, they are placed on the pedals or on the ground at will when charging. Since the input and output wires of the charger are not very long, the wires will be pulled, resulting in poor contact when plugging in, and the input and output wires will be broken. In addition, the charger is placed on the ground, which is inevitably exposed to dust and rain! Damage to the charger.

[0004] Although the above patent solves the problem of pulling by facilitating the fixation of the charger when charging the electric vehicle and avoiding the poor contact caused by pulling the wires during charging, the wires on both sides are fixed and relatively long, making storage more troublesome. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide an electric vehicle charger, which limits the cable by a driving block to prevent it from moving forward again, and prevents excessive pulling that causes the cable to be pulled and broken, thereby providing better protection for the cable. The contact position between the cable and the heavy block at the pulling point is protected by a rubber sleeve to prevent the cable from being excessively bent and damaged. A cavity for accommodating the cable is reserved inside the charger casing, so that the cable can reach the inside of the charger casing, making it more convenient to store the cable and avoiding the cable being exposed to the outside and easily damaged.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A battery vehicle charger comprises a charger shell, wherein a protection mechanism is arranged inside the charger shell, a rainproof mechanism is arranged on the right side of the protection mechanism, the rainproof mechanism comprises a weight block fixedly connected to the inside of the charger shell, and a rubber sleeve is fixedly connected to the right side of the weight block;

[0008] The protection mechanism includes a mounting frame fixedly connected to the inside of the charger housing, a circular ring fixedly connected to the outer surface of the mounting frame, a second circular disk movably connected to the inside of the circular ring, a cable fixedly connected to the right side of the second circular disk, a left end of the cable passes through the second circular disk and extends to the inside of the charger housing, the surface of the cable extends to form a driving block, and the end of the driving block away from the weight block is spirally wound on the surface of the cable.

[0009] Furthermore, a return torsion spring is welded between the second disk and the ring, a limiting plate is fixedly connected to the right side of the mounting frame, a second circular hole is opened at the inner top of the limiting plate, the limiting plate fits against the right side of the cable, and the right end of the cable passes through the second circular hole and extends to the outside of the charger casing.

[0010] The inner axial section of the limiting plate is in a grid shape, the back side of the second disc is connected to the inner side of the mounting frame by rotation, and the reset torsion spring is in a naturally stretched state.

[0011] Furthermore, a second limiting rod is fixedly connected to the inner bottom of the charger housing, and the top of the second limiting rod extends to form a limiting disk. The right end of the cable passes through the limiting disk and extends to the outside of the weight block.

[0012] Furthermore, the left side of the weight block is rotatably connected to a first disc, a first vent hole is provided inside the weight block, and a second vent hole annularly offset from the first vent hole is provided inside the first disc.

[0013] Furthermore, the right side of the first disc extends to form an extension block, an arc-shaped groove is opened inside the weight block at a position corresponding to the extension block, the extension block is slidably connected to the inside of the arc-shaped groove, a spring is welded inside the arc-shaped groove, and the spring is in a naturally extended state.

[0014] Furthermore, the left side of the first disc extends to form a first limiting rod, the left side of the first limiting rod extends to form a driving disc, and the cable passes through the driving disc.

[0015] Furthermore, the weight block is slidably connected to the inside with a first sealing block, the first vent hole and the first sealing block are staggered, a movable groove is provided inside the weight block at a position corresponding to the first sealing block, the first sealing block is fixedly connected to the inside with an extrusion block, the extrusion block is fixedly connected to the contact surface of the weight block, and the inside of the extrusion block is hollow.

[0016] Furthermore, a second sealing block is slidably connected inside the first disc, the second sealing block and the second vent hole are arranged alternately, and the axial cross-section shape and size of the first sealing block and the second vent hole are the same.

[0017] Furthermore, a plurality of discharge troughs are provided inside the first disc, and a plurality of first circular holes communicating with the second vent holes are provided at the bottom of the discharge troughs.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. This solution uses a driving block to limit the cable to prevent it from moving forward again, and prevents excessive pulling that may cause the cable to be pulled and broken, thereby providing better protection for the cable. The rubber sleeve is used to protect the contact position between the cable and the heavy block at the pulling point to prevent the cable from being excessively bent and damaged. A cavity for accommodating the cable is left inside the charger casing, allowing the cable to reach the inside of the charger casing, making it more convenient to store the cable and preventing the cable from being exposed to the outside and easily damaged.

[0020] 2. In this solution, after the cable is loosened, the cable rotates along with the second disc due to the rotation of the reset torsion spring driving the second disc, and the second disc and the limiting plate clamp the cable between them, so that the cable rotates into a threaded shape, making it easier to pull out the cable again after storage, avoiding the cables from being mixed and bundled together inside the charger casing, making it difficult to pull out the cables, and making it more convenient to store the cables.

[0021] 3. This solution ensures that there is a certain distance between the limiting disk and the weight block, and the limiting disk blocks the cable from moving again to prevent the cable from being pulled too hard, causing the cable to be pulled out again and causing damage to the device. It is difficult to protect the cable again through the limiting disk at the bend of the drive block.

[0022] 4. In this solution, the extension block rotates the first disc to the original position, so that the first vent hole and the second vent hole are staggered, thereby preventing external dust and water from reaching the inside of the charger casing, and better protecting the circuit in the device. Since the position of the limiting disk is fixed, the cable can be prevented from being entangled in the charger casing due to the torsional force. The weight block is relatively heavy, causing the center of gravity of the charger casing to be close to one side of the weight block. When the device falls, one side of the weight block faces downward, and there is no circuit component on the side of the charger casing close to the weight block, which better protects the device and prevents it from being damaged by falling.

[0023] 5. In this solution, the first sealing block is inserted into the inside of the second vent due to the elasticity of the extrusion block, and the second sealing block is also inserted into the inside of the first vent, so that the closure between the weight block and the first disc is tighter, preventing water from reaching the inside of the charger housing through the gap between the weight block and the first disc due to rain, causing circuit damage.

[0024] 6. This solution adds silica gel desiccant inside the discharge trough to absorb the water vapor that reaches the inside of the discharge trough through the first circular hole, preventing the water vapor from reaching the inside of the charger housing through the weight block and the first disc after sealing, causing corrosion of the circuit board. The silica gel desiccant can be dried and reused, and the heat generated when the device is working can also dry the silica gel desiccant, which is more convenient to use and has a better waterproof effect.

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0036] Embodiment 1:

[0037] See also Figures 1 to 4 A battery vehicle charger comprises a charger housing 1, wherein a protective mechanism 4 is arranged inside the charger housing 1, and a rainproof mechanism 2 is arranged on the right side of the protective mechanism 4, wherein the rainproof mechanism 2 comprises a weight block 21 fixedly connected to the inside of the charger housing 1; the protective mechanism 4 comprises a mounting frame 41 fixedly connected to the inside of the charger housing 1, a circular ring 44 is fixedly connected to the outer surface of the mounting frame 41, a second circular disc 46 is movably connected inside the circular ring 44, a cable 42 is fixedly connected to the right side of the second circular disc 46, a left end of the cable 42 passes through the second circular disc 46 and extends to the inside of the charger housing 1, a surface of the cable 42 extends to form a driving block 421, and an end of the driving block 421 away from the weight block 21 is spirally wound on the surface of the cable 42.

[0038] To store the cable 42, it is only necessary to squeeze the cable 42 to move the cable 42 to one side of the mounting frame 41. A cavity for accommodating the cable 42 is reserved inside the charger housing 1, so that the cable 42 can reach the inside of the charger housing 1, making it more convenient to store the cable 42 and avoiding the cable 42 being exposed to the outside. Not only is it troublesome to store, but the cable 42 exposed to the outside is also easily damaged. The cable 42 needs to be connected to the circuit. After the damaged cable 42 is connected to the circuit, the consequences of the accident are more dangerous. When the cable 42 is needed, it is only necessary to pull the weight block 21. The cable 42 on the right side allows the cable 42 to reach the position of the weight block 21 with the driving block 421. After the bend in the driving block 421 reaches the left side of the weight block 21, the bend cannot pass through the weight block 21, and is restricted by the driving block 421 to prevent the cable 42 from moving forward again, thereby preventing excessive pulling that causes the cable 42 to be pulled and broken. The protection effect of the cable 42 is better, and the contact position between the cable 42 and the weight block 21 at the pulling point is protected by the rubber sleeve 3 to prevent the cable 42 from excessive bending that causes damage to the cable 42.

[0039] like Figures 2 to 3As shown, a reset torsion spring 45 is welded between the second disk 46 and the ring 44, a limiting plate 43 is fixedly connected to the right side of the mounting frame 41, a second circular hole 431 is opened on the inner top of the limiting plate 43, the limiting plate 43 fits the right side of the cable 42, the right end of the cable 42 passes through the second circular hole 431 and extends to the outside of the charger housing 1, the internal axial section of the limiting plate 43 is grid-shaped, the back side of the second disk 46 is connected to the inner side of the mounting frame 41 by rotation, and the reset torsion spring 45 is in a naturally stretched state.

[0040] By pulling the cable 42, the cable 42 passes through the second circular hole 431 and then passes through the weight block 21 to the tail, and while the cable 42 moves, the driving block 421 passes through the second disc 46, and the driving block 421 with a threaded tail guides the second disc 46 to rotate the second disc 46, and a return torsion spring 45 is connected between the second disc 46 and the ring 44, so that the second disc 46 rotates and drives the return torsion spring 45 to move, and the ring 44 is connected to the mounting frame 41, so that the second disc 46 rotates more stably, and the cable 42 moves. 42 is sandwiched between the second disc 46 and the limiting plate 43, so that the rotation of the second disc 46 is more stable. After the cable 42 is released, the cable 42 rotates along with the second disc 46 driven by the return torsion spring 45, and the second disc 46 and the limiting plate 43 sandwich the cable 42 therebetween, so that the cable 42 rotates into a threaded shape, making it easier to pull out the cable 42 after storage, avoiding the cables 42 from being mixed and bundled together inside the charger housing 1, making it difficult to pull out the cables 42, and making it more convenient to store the cables 42.

[0041] like Figure 4 As shown, a second limiting rod 26 is fixedly connected to the inner bottom of the charger housing 1, and the top of the second limiting rod 26 extends to form a limiting plate 24. The right end of the cable 42 passes through the limiting plate 24 and extends to the outside of the weight block 21.

[0042] The driving block 421 first passes through the limiting disk 24, and then passes through the weight block 21 again, so that the bending part of the driving block 421 first passes through the limiting disk 24 before reaching the weight block 21. There is still a certain distance between the limiting disk 24 and the weight block 21, and the limiting disk 24 blocks the cable 42 from moving again to prevent the cable 42 from being pulled too hard, causing the cable 42 to be pulled out again and causing damage to the device. It is difficult to protect the cable 42 again through the limiting disk 24 at the bending part of the driving block 421.

[0043] like Figures 4 to 6As shown, the left side of the weight block 21 is rotatably connected to the first disk 22, the inside of the weight block 21 is provided with a first vent hole 211, the inside of the first disk 22 is provided with a second vent hole 222 annularly offset with the first vent hole 211, the right side of the first disk 22 is extended to form an extension block 221, the inside of the weight block 21 is provided with an arc groove 213 at a position corresponding to the extension block 221, the extension block 221 is slidably connected to the inside of the arc groove 213, the inside of the arc groove 213 is welded with a spring 5, and the spring 5 is in a naturally stretched state, the left side of the first disk 22 is extended to form a first limiting rod 25, the left side of the first limiting rod 25 is extended to form a driving disk 23, and the cable 42 passes through the driving disk 23.

[0044] When the battery vehicle is to be charged through the device, the cable 42 needs to be pulled so that the bending part of the surface of the cable 42 first passes through the driving disk 23, and the driving disk 23 is connected to the first disk 22 through the first limiting rod 25, and the driving disk 23 is driven to rotate by the inclined surface of the driving block 421, so that the driving disk 23 rotates with the first limiting rod 25, and the first disk 22 is rotatably connected to the weight block 21, so that the first limiting rod 25 rotates with the first disk 22, and the rotation of the first disk 22 rotates the second vent 222 inside the first disk 22, so that the second vent 222 coincides with the first vent 211 inside the weight block 21, so that the heat inside the device can be transferred out, and the rotation of the first disk 22 drives the extension block 221 to rotate inside the arc groove 213, so that the extension block 221 squeezes the spring 5, and when the device is to be stored, it is stored inside the charger housing 1 through the cable 42, so that the cable 42 moves with the driving block 421, and the driving block 421 is moved from the inside of the driving disk 23 The first disc 22 is moved away from the extension block 221, and the extension block 221 moves inside the arc groove 213. The extension block 221 rotates to the original position with the first disc 22, and the first disc 22 returns to the original position with the first limiting rod 25, so that the first vent 211 and the second vent 222 are staggered to prevent external dust and water from reaching the interior of the charger housing 1, and the circuit protection effect in the device is better. The driving block 421 on the surface of the cable 42 passes through the limiting disk 24 and the driving disk 23. Since the position of the limiting disk 24 is fixed, the cable 42 can be prevented from being entangled in the charger housing 1 due to the torsional force. It is more troublesome to untangle the cable 42 in the charger housing 1. The weight block 21 is relatively heavy, resulting in the center of gravity of the charger housing 1 being close to one side of the weight block 21. When the device falls, the side of the weight block 21 is downward, and there is no circuit component on the side of the charger housing 1 close to the weight block 21, which has a better protection effect on the device and prevents it from falling and being damaged.

[0045] like Figure 7As shown, the weight block 21 is internally slidably connected with a first sealing block 212, the first vent hole 211 and the first sealing block 212 are staggered, a movable groove 214 is provided inside the weight block 21 at a position corresponding to the first sealing block 212, the first sealing block 212 is internally fixedly connected with an extrusion block 2121, the extrusion block 2121 is fixedly connected to the contact surface of the weight block 21, the interior of the extrusion block 2121 is hollowed out, the first disc 22 is internally slidably connected with a second sealing block 223, the second sealing block 223 and the second vent hole 222 are staggered, and the axial cross-section shape and size of the first sealing block 212 and the second vent hole 222 are the same.

[0046] By rotating the first disc 22, the first vent 211 and the second vent 222 are staggered, and the first sealing block 212 is squeezed while rotating, so that the squeezing block 2121 is squeezed and deformed, and the first sealing block 212 retracts into the inside of the movable groove 214, so that one side of the charger housing 1 is closed, so that the second vent 222 reaches the position of the first sealing block 212, and the first sealing block 212 is elastically stuck in the inside of the second vent 222 due to the squeezing block 2121, and the second sealing block 223 is also stuck in the inside of the first vent 211, so that the closure between the weight block 21 and the first disc 22 is tighter, preventing water from reaching the inside of the charger housing 1 through the gap between the weight block 21 and the first disc 22 due to rain outside, causing circuit damage.

[0047] like Figure 8 As shown, a plurality of discharge grooves 224 are provided inside the first disc 22 , and a plurality of first circular holes 225 communicating with the second vent holes 222 are provided at the bottom of the discharge grooves 224 .

[0048] By adding silica gel desiccant inside the discharge trough 224, water vapor can reach the inside of the discharge trough 224 through the first circular hole 225, and the water vapor is adsorbed by the silica gel desiccant to prevent the water vapor from reaching the inside of the charger housing 1 again through the weight block 21 and the first disc 22 after sealing, causing circuit board corrosion. The silica gel desiccant can be dried and reused, and the heat generated when the device is working can also dry the silica gel desiccant, which is more convenient to use and has a better waterproof effect.

[0049] Instructions for use: by pulling the cable 42, the cable 42 rotates with the second disc 46, thereby driving the reset torsion spring 45 to deform, so that after the cable 42 is released, the reset torsion spring 45 drives the cable 42 to wind again, and moves with the driving block 421 during the pulling process, and the limiting disk 24 is pressed against the bending part of the driving block 421 to prevent the cable 42 from being pulled again, and the driving disk 23 is driven to rotate with the first disc 22 through the rotation of the driving block 421. When the cable 42 is pulled to charge, the second vent 222 in the first disc 22 overlaps with the first vent 211 for heat dissipation, while in other cases the second vent 222 is staggered with the first vent 211 to prevent foreign matter from entering, and silica gel desiccant is added to the inside of the discharge trough 224 to absorb the water vapor that reaches the inside of the discharge trough 224 through the first circular hole 225, and the silica gel desiccant is dried by the heat generated during the heat dissipation, and is reused.

[0050] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
