Description

Technical Field

[0001] The invention belongs to the technical field of distribution boxes, in particular to an outdoor distribution box. Background Art

[0002] Home use of new energy vehicle charging piles outdoors for a long time, the charging piles cannot avoid wind, sun and other man-made damage, which greatly reduces the service life of the charging piles. In order to ensure the safe and stable operation of the charging piles, at present, the charging piles used outdoors are equipped with distribution boxes. The distribution boxes are waterproof and dustproof, suitable for outdoor installation and use, ensuring normal operation in various harsh environments.

[0003] Before the existing distribution box for charging piles is used, the charging pile body is fixedly installed in the distribution box, and the charging line and the charging gun are stored in the distribution box. When the new energy vehicle needs to be charged, the distribution box is opened, and then the charging gun is taken out and inserted into the charging place of the new energy vehicle. The length of the charging line is generally designed to be longer in order to meet the parking distance of the vehicle. However, after the charging line is taken out of the distribution box, the excess part of the charging line will fall on the ground. On rainy days, rain mixed with dust on the ground will adhere to the charging line, making the charging line dirty, which causes trouble for the user to put the charging line into the distribution box later. Secondly, the charging line that falls on the ground is easily stepped on, causing wear of the protective layer of the charging line, thereby reducing the service life of the charging line. For this reason, the present invention provides an outdoor distribution box. Summary of the invention

[0004] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an outdoor distribution box described in the present invention comprises a support seat, a distribution box body is fixedly installed on the upper end of the support seat, a box door is arranged on one side of the distribution box body, a winding mechanism for winding up the charging line is arranged in the distribution box body, the winding mechanism comprises a winding disk, the winding disk is fixedly installed in the distribution box body, a fixed cover is fixedly installed on one side of the winding disk, a swivel shaft rotatably connected to the fixed cover, one end of the swivel shaft is fixedly connected to a winding arm, and the other end of the swivel shaft is connected to a motor, a plurality of pairs of lead wheels for guiding the charging line are rotatably installed in the winding arm, an installation groove is opened in the middle of one side of the winding disk, the motor is located in the installation groove, an annular groove is arranged on the lead wheel, and the annular groove clamps the charging line;

[0006] Since the charging cable is wound on the reel in advance, during the charging process of the new energy vehicle, the winding mechanism can release the charging cable of an appropriate length according to how far the car is parked. The charging cable will not fall to the ground due to being too long, thus preventing the charging cable from being contaminated by ground stains and stepped on, thereby increasing the service life of the charging cable.

[0007] Preferably, the winding mechanism further comprises two sets of driving wheels, which are symmetrically mounted on both sides of the winding arm, one set of driving wheels is mounted with a gear at the end thereof, a gear ring meshing with the gear, the gear ring is fixedly sleeved on the fixed cover, the charging line is located between the two sets of driving wheels, and the driving wheels are rotated to connect the charging line;

[0008] The driving wheel drives the charging cable to be transmitted in an amount equal to the amount of charging cable released by the reel, so that the charging cable is automatically transmitted out of the distribution box body. When using, you only need to hold the transmitted charging cable until the charging gun can be inserted into the charging port of the new energy vehicle, thereby ensuring that the charging cable can be smoothly released from the reel.

[0009] Preferably, a storage mechanism for storing the charging gun is provided below the winding mechanism, the storage mechanism comprises a storage box, the storage box is fixedly installed in the main body of the distribution box, a guide tube is fixedly connected to the upper end of the storage box, a movable sleeve is movably installed in the storage box, a spring is provided above the movable sleeve, a rotary tube rotatably installed in the storage box, an end plate fixedly connected to the lower end of the rotary tube, an avoidance groove is provided at the lower end of the storage box, the lower end of the storage box is fixedly connected to the avoidance groove, the lower end of the spring is fixedly connected to the movable sleeve, the upper end of the spring is fixedly connected to the inner wall of the storage box, a pin shaft is provided on the outer ring of the movable sleeve, an air avoidance groove is provided on one side of the storage box, a guide groove is provided on the rotary tube, the pin shaft passes through the air avoidance groove and goes into the guide groove, and the guide groove consists of a linear slide groove and a spiral slide groove;

[0010] The pin shaft enters into the spiral slide groove, and the pin shaft will squeeze the inner wall of the spiral slide groove, causing the rotary tube to rotate together with the end sealing plate until the end sealing plate blocks the lower end of the storage box, thereby realizing the storage of the charging gun into the storage box. During this process, the user does not need to open or close the box door again, which is more convenient and efficient for the user to put away the charging cable and charging gun.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. Since the charging cable is wound on the reel in advance, during the charging process of the new energy vehicle, the reel can release the charging cable of appropriate length according to the distance the car is parked. The charging cable will not fall on the ground due to being too long, thus preventing the charging cable from being contaminated by ground stains and stepped on, thereby increasing the service life of the charging cable.

[0013] 2. When the winding arm rotates to release the charging cable, the gear will rotate with the winding arm and roll along the gear ring. The rolling gear drives the corresponding driving wheel to rotate, and the rotating driving wheel drives the charging cable to be transmitted. The driving wheel drives the charging cable to be transmitted in an amount equal to the amount of the charging cable released by the winding reel, so that the charging cable is automatically transmitted out of the distribution box body. When using, you only need to lift the transmitted charging cable until the charging gun can be inserted into the charging port of the new energy vehicle, thereby ensuring that the charging cable can be smoothly released from the winding reel.

[0014] 3. Drive the winding arm to rotate. During the process of the winding arm winding the charging cable around the winding reel, the charging cable will pass through the storage box and the guide tube in turn and enter the winding arm until the charging gun is received directly under the storage box. At this time, the user releases the charging gun, and as the charging cable continues to be wound around the winding reel, the charging gun will be collected into the storage box, and the tail of the charging gun will squeeze the movable sleeve to make the movable sleeve move upward along the inner cavity of the storage box. At the same time, the movable sleeve drives the pin shaft to move upward along the linear slide groove. When the pin shaft moves to the intersection of the linear slide groove and the spiral slide groove, the head of the charging gun completely enters the storage box. As the pin shaft enters the spiral slide groove, the pin shaft will squeeze the inner wall of the spiral slide groove, causing the rotary tube to rotate together with the sealing end plate until the sealing end plate blocks the lower end of the storage box, thereby realizing the collection of the charging gun into the storage box. In this process, the user does not need to open or close the box door again, which is more convenient and efficient for the user to put away the charging cable and charging gun.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0025] like Figures 1 to 3 As shown, an outdoor distribution box described in an embodiment of the present invention comprises a support base 1, a distribution box body 2 is fixedly installed on the upper end of the support base 1, a box door 3 is arranged on one side of the distribution box body 2, a winding mechanism 4 for winding up the charging line 5 is arranged in the distribution box body 2, and the winding mechanism 4 comprises a winding disk 401, the winding disk 401 is fixedly installed in the distribution box body 2, a fixed cover 402 is fixedly installed on one side of the winding disk 401, a rotating shaft 403 rotatably connected to the fixed cover 402, one end of the rotating shaft 403 is fixedly connected to a winding arm 404, and the other end of the rotating shaft 403 is connected to a motor 406, and a plurality of pairs of lead wheels 405 for guiding the charging line 5 are rotatably installed in the winding arm 404, a mounting groove 4011 is opened in the middle of one side of the winding disk 401, the motor 406 is located in the mounting groove 401, and an annular groove 57 is arranged on the lead wheel 405, and the annular groove 57 engages the charging line 5.

[0026] Specifically, the support base 1 is fixedly installed on the outdoor ground. In the initial state, the charging line 5 is coiled on the winding reel 401, and the charging line 5 passes through multiple pairs of lead wheels 405 in the winding arm 404. The charging gun 6 is placed in the distribution box body 2, and the box door 3 is in a closed state. When the new energy vehicle needs to be charged, the box door 3 is opened, the user picks up the charging gun 6, and then starts the motor 406. The motor 406 drives the rotary shaft 403 to rotate together with the winding arm 404, and the lower attached Figure 3The direction indicated by the middle arrow is the rotation direction, so that the charging line 5 wound on the winding drum 401 is released, and at the same time the user drags the charging gun 6, and the charging gun 6 pulls the charging line 5, and the charging line 5 released from the winding drum 401 passes through the multiple pairs of lead wheels 405 in the winding arm 404 in turn, and the charging line 5 drives the lead wheels 405 to rotate. Under the guidance of the multiple pairs of lead wheels 405, the charging line 5 released from the winding drum 401 is transmitted out of the distribution box body 2 until the charging gun 6 can be inserted into the charging port of the new energy vehicle, and the operation of the motor 406 is paused at this time. On the contrary, when the charging cable 5 is wound up, the motor 406 drives the rotary shaft 403 together with the winding arm 404 to reverse, so that the charging cable 5 is wound on the winding drum 401. Compared with the prior art, since the charging cable 5 is wound on the winding drum 401 in advance, during the charging of the new energy vehicle, the winding mechanism 4 can release the charging cable 5 of an appropriate length according to the distance the car is parked. The charging cable 5 will not fall on the ground due to being too long, thereby preventing the charging cable 5 from being contaminated by ground stains and stepped on, thereby improving the service life of the charging cable 5.

[0027] like Figure 4 As shown, the winding mechanism 4 also includes two sets of driving wheels 407, which are symmetrically mounted on both sides of the winding arm 404, and a gear 408 is mounted on the end of one set of driving wheels 407, and a gear ring 409 meshing with the gear 408 is fixedly mounted on the fixed cover 402. The charging cable 5 is located between the two sets of driving wheels 407, and the driving wheels 407 are rotatably connected to the charging cable 5.

[0028] Specifically, during the process of releasing the charging cable 5 from the winding reel 401, the charging cable 5 needs to be manually pulled synchronously at the same time. Since the amount of manual pulling of the charging cable 5 cannot be controlled, if the pulling amount is less than the release amount of the winding reel 401, the rotating winding arm 404 will cause the charging cable 5 to become tangled, affecting the subsequent winding of the charging cable 5. If the pulling amount is greater than the release amount of the winding reel 401, the charging cable 5 will be straightened all at once, and the straightened charging cable 5 will increase the friction with the lead wheel 405, reducing the service life of the charging cable 5. Therefore, when the winding arm 404 is rotating to release the charging cable 5, the charging cable 5 will be tied to a knot. During the process, the gear 408 will rotate with the winding arm 404, and the gear 408 will roll along the gear ring 409. The rolling gear 408 drives the corresponding driving wheel 407 to rotate, and the rotating driving wheel 407 drives the charging cable 5 to be transmitted. The driving wheel 407 drives the charging cable 5 to be transmitted in an amount equal to the amount of the charging cable 5 released by the winding reel 401, so that the charging cable 5 is automatically transmitted out of the distribution box body 2. The user only needs to carry the transmitted charging cable 5 until the charging gun 6 can be inserted into the charging port of the new energy vehicle, thereby ensuring that the charging cable 5 can be smoothly released from the winding reel 401. Embodiment 2

[0029] like Figures 5 to 7As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a storage mechanism 7 for storing the charging gun 6 is provided below the winding mechanism 4, the storage mechanism 7 includes a storage box 701, the storage box 701 is fixedly installed in the distribution box body 2, a guide tube 702 is fixedly connected to the upper end of the storage box 701, a movable sleeve 703 is movably installed in the storage box 701, a spring 704 is provided above the movable sleeve 703, a rotary tube 705 is rotatably installed in the storage box 701, an end sealing plate 706 is fixedly connected to the lower end of the rotary tube 705, and the storage box An avoidance groove 201 is provided at the lower end of 701, and the lower end of the storage box 701 is fixedly connected to the avoidance groove 201, the lower end of the spring 704 is fixedly connected to the movable sleeve 703, and the upper end of the spring 704 is fixedly connected to the inner wall of the storage box 701. A pin shaft 7031 is provided on the outer ring of the movable sleeve 703, and an avoidance groove 7011 is provided on one side of the storage box 701. A guide groove 7051 is provided on the rotating tube 705, and the pin shaft 7031 passes through the avoidance groove 7011 and goes along to the guide groove 7051. The guide groove 7051 is composed of a linear slide groove 511 and a spiral slide groove 512.

[0030] Specifically, the inner wall of the movable sleeve 703 is smooth, and the inner diameter of the movable sleeve 703 is slightly larger than the outer diameter of the charging cable 5. It generally takes a certain amount of time to charge a new energy vehicle. Therefore, the user generally closes the box door 3 after inserting the charging gun 6 into the charging port of the new energy vehicle, and then leaves. After the new energy vehicle is fully charged, the box door 3 is opened, and then the charging cable 5 and the charging gun 6 are put into the distribution box body 2, and finally the box door 3 is closed. The box door 3 is opened and closed repeatedly, which makes it troublesome for the user to put away the charging cable 5 and the charging gun 6, and wastes time. When putting away the charging cable 5 and the charging gun 6, the winding arm 404 is driven to rotate. During the process of the winding arm 404 winding the charging cable 5 around the winding reel 401, the charging cable 5 will pass through the storage box 701 and the guide tube 702 in turn and enter the winding arm 404 until the charging gun 6 is received directly below the storage box 701. At this time, the user releases the charging gun 6, and as the charging cable 5 and the charging gun 6 are put into the winding reel 401, the user releases the charging gun 6. 5 continues to be wound on the winding reel 401, the charging gun 6 will be stored in the storage box 701, and the tail of the charging gun 6 will squeeze the movable sleeve 703, so that the movable sleeve 703 moves upward along the inner cavity of the storage box 701, and the movable sleeve 703 drives the pin shaft 7031 to move upward along the linear slide groove 511. When the pin shaft 7031 moves to the intersection of the linear slide groove 511 and the spiral slide groove 512, the head of the charging gun 6 completely enters the storage box 701. As the pin shaft 7031 enters the spiral slide groove 512, the pin shaft 7031 squeezes the inner wall of the spiral slide groove 512, so that the rotary tube 705 rotates together with the end sealing plate 706 until the end sealing plate 706 blocks the lower end of the storage box 701, thereby realizing the storage of the charging gun 6 in the storage box 701. In this process, the user does not need to open or close the box door 3 again, which is more convenient and efficient for the user to put away the charging cable 5 and the charging gun 6.

[0031] Working principle: Open the box door 3, the user picks up the charging gun 6, and then starts the motor 406, which drives the rotating shaft 403 and the winding arm 404 to rotate. Figure 3 The direction indicated by the middle arrow is the direction of rotation, so that the charging cable 5 wound on the winding disk 401 is released, and at the same time the user drags the charging gun 6, and the charging gun 6 pulls the charging cable 5, and the charging cable 5 released from the winding disk 401 passes through the multiple pairs of lead wheels 405 in the winding arm 404 in turn, and the charging cable 5 drives the lead wheels 405 to rotate, and under the guidance of the multiple pairs of lead wheels 405, the charging cable 5 released from the winding disk 401 is transmitted out of the distribution box body 2 until the charging gun 6 can be inserted into the charging port of the new energy vehicle, and the motor 406 is stopped at this time. On the contrary, when the charging cable 5 is wound up, the motor 406 drives the rotary shaft 403 and the winding arm 404 to reverse, so that the charging cable 5 is wound on the winding disk 401;

[0032] When the winding arm 404 rotates to release the charging line 5, the gear 408 rotates with the winding arm 404, and the gear 408 rolls along the gear ring 409. The rolling gear 408 drives the corresponding driving wheel 407 to rotate, and the rotating driving wheel 407 drives the charging line 5 to be transmitted. The driving wheel 407 drives the charging line 5 to be transmitted by an amount equal to the amount of the charging line 5 released by the winding reel 401, so that the charging line 5 is automatically transmitted out of the distribution box body 2.

[0033] When the charging cable 5 and the charging gun 6 are retracted, the winding arm 404 is driven to rotate. During the process of winding the charging cable 5 on the reel 401, the charging cable 5 will successively pass through the storage box 701 and the guide tube 702 and enter the winding arm 404 until the charging gun 6 is received directly under the storage box 701. At this time, the user releases the charging gun 6. As the charging cable 5 continues to be wound on the reel 401, the charging gun 6 will be received in the storage box 701, and the tail of the charging gun 6 will squeeze the movable sleeve 703, so that the movable sleeve 703 Move upward along the inner cavity of the storage box 701, and at the same time, the movable sleeve 703 drives the pin shaft 7031 to move upward along the linear slide groove 511. When the pin shaft 7031 moves to the intersection of the linear slide groove 511 and the spiral slide groove 512, the head of the charging gun 6 completely enters the storage box 701. As the pin shaft 7031 enters the spiral slide groove 512, the pin shaft 7031 will squeeze the inner wall of the spiral slide groove 512, causing the rotary tube 705 to rotate together with the end plate 706 until the end plate 706 blocks the lower end of the storage box 701.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
