Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and more specifically, to a charging pile and a top-mounted charging system. Background Technology

[0002] As the number of new energy vehicles increases daily, higher demands are being placed on the quantity and ease of use of charging stations. Due to existing site limitations, the charging problem for new energy vehicles is becoming increasingly prominent. Most existing charging stations for new energy vehicles are installed vertically on the ground or mounted on walls and columns. This installation method occupies ground space, especially in small spaces such as garages and underground parking lots. The charging machines are prone to water damage, and the charging cables are easily contaminated, crushed, or even damaged or knocked down, which is not conducive to management and electrical safety. It may also cause pedestrians to have difficulty passing and trip. According to the "Technical Standard for Distributed Charging Facilities for Electric Vehicles GBT51313-2018", additional space for charging stations and waterproofing are required at the rear of the vehicle, which increases the construction cost of the garage.

[0003] Chinese patent CN202220861266.5 discloses a ceiling-mounted charging pile, which includes a housing and a mounting base on the housing for mounting different structures of mounting frames. The mounting base and the mounting frame are detachably connected. The mounting frames with different structures are used for ceiling-mounted installation at different installation positions on the main body of the building. A telescopic winding reel is provided inside the housing, and a charging cable is wound inside the telescopic winding reel. One end of the charging cable is provided with a charging gun. This solution adopts a ceiling-mounted installation design.

[0004] The problems with the aforementioned patented solutions are as follows: the charging pile mounting bracket occupies a large horizontal area on the garage ceiling, which, given the existing indoor garage ceiling includes other fire protection and lighting facilities, results in insufficient installation space; the mounting bracket and housing structure, due to their weight and large surface area, require multiple installation points and fasteners, leading to slow construction; and the dangling pull rings, cables, and charging heads lack restraints, leaving them vulnerable to accidental contact or snagging. Therefore, it is necessary to develop a charging pile that can efficiently utilize existing garage ceiling space while ensuring ease of use and installation, and achieving good economic efficiency. Utility Model Content

[0005] In view of the above-mentioned defects or improvement needs of the existing technology, this utility model provides a charging pile that can effectively utilize the installation space of the indoor ceiling during installation without occupying the ground space, and achieves convenient charging operation by combining the characteristics of flexible cable.

[0006] To achieve the above objectives, this utility model provides a charging pile, comprising a charging head and a housing electrically connected to the end of a cable, and a fixing frame, a first bracket, and a second bracket arranged sequentially from top to bottom. The fixing frame and / or the first bracket are fixed inside the housing. The cable passes downward through the fixing frame, the first bracket, and the second bracket in sequence, forming an elastic segment between the first bracket and the second bracket. The two ends of the elastic segment are a first transition segment passing through the first bracket and a second transition segment passing through the second bracket, respectively. The second transition segment is electrically connected to the charging head. The first bracket is used to convert the cable of the first transition segment from a straight state to an arc state, and the second bracket is used to convert the cable of the second transition segment from an arc state to a straight state. In the non-working state, the elastic segment and the second bracket are located inside the housing, and in the working state, a portion of the elastic segment and the second bracket extend out from inside the housing.

[0007] The working principle of this charging station is as follows: When charging a vehicle, the charging head is pulled down by hand, and the elastic section stretches to the position of the vehicle's charging port. After use, the charging head retracts into the outer shell under the elastic force of the elastic section. The transition section keeps the cable and the outer shell coaxial under the constraint of the first and second brackets. The first transition section is kept centered by the limiting effect of the first bracket, and the second transition section is kept centered by the limiting effect of the second bracket, reducing the impact and friction between the charging head and the outer shell during the extension and retraction process.

[0008] Furthermore, the first bracket includes a limiting groove, and the first transition section is limited within the limiting groove, with the axes of the first transition section and the limiting groove coinciding; the second bracket includes a spiral channel, and the second transition section is limited within the spiral channel, with the axes of the second transition section and the spiral channel coinciding; the second transition section extends from the bottom of the second bracket and connects to the charging head; the first bracket and the second bracket respectively eliminate the stress on the first transition section and the second transition section, preventing the charging head from deviating from the axis.

[0009] Furthermore, the spiral channel includes a first channel and a second channel for the passage of the second transition section. The second bracket includes a first limiting block and a second limiting block fixed along the fastening surface. The two are fixed to form the first channel and the second channel. The first channel and the second channel have the same spiral radius and outer diameter as the second transition section. The second bracket is designed to be installed by fastening the first limiting block and the second limiting block, which facilitates the combination and installation of the curved transition section cable with the second bracket. The first channel and the second channel can reduce the stress interference of the transition section on the vertical expansion and contraction of the elastic section.

[0010] Furthermore, a pin is provided at the bottom of the first limiting block, and a pin groove is provided on the second limiting block at a position corresponding to the pin. The pin is inserted into the pin groove to achieve the limiting.

[0011] Furthermore, a pin is provided at the bottom of the first limiting block, and a pin groove is provided on the second limiting block at a position corresponding to the pin. The pin is inserted into the pin groove to achieve limiting. A charging head mounting hole is provided at the bottom of the second bracket, and a buckle is provided at the bottom of the pin, which is arranged radially along the charging head mounting hole. The charging head is engaged with the charging head mounting hole through the buckle, which facilitates the assembly of the first limiting block and the second limiting block. The buckle connection method facilitates the installation of the charging head.

[0012] Furthermore, the fixing frame is provided with a spring-loaded component, which is connected to the second bracket via a pull rope to provide a stable pulling force for the second bracket and the charging head to retract into the outer shell.

[0013] Furthermore, the first bracket is provided with a first wire hole, and the second bracket is provided with a second wire hole. The pull rope passes through the first wire hole, the second wire hole, and the charging head mounting hole from top to bottom in sequence.

[0014] Furthermore, the fixing frame includes a first mounting plate and a second mounting plate arranged in parallel, which are fixedly connected by a support column. The first support column is fixed to the bottom surface of the second mounting plate. The use of the support column for fixing increases the internal storage space of the fixing frame and reduces the overall weight.

[0015] To facilitate users in removing the charging head from the casing, a pull cord is attached to the charging head.

[0016] Furthermore, according to a second aspect of this utility model, a top-mounted charging system is provided, which includes the charging pile, the charging pile being suspended on a suspension mechanism on the indoor ceiling, avoiding occupying indoor floor space, making full use of indoor ceiling space, and preventing cables from being placed on the ground and getting dusty and tripping pedestrians.

[0017] Furthermore, the suspension mechanism includes a hook fixed to the indoor ceiling and a hanging ring suspended from the hook; the cable is connected to the hanging ring via an adjusting collar. The suspension mechanism allows for adjustment of the charging pile's hanging height. The suspension method is simple and adaptable to most existing indoor parking lot ceiling installation structures.

[0018] In summary, compared with the prior art, the above-described technical solution conceived by this utility model can achieve the following beneficial effects:

[0019] (1) This utility model provides a charging system that effectively utilizes the installation space of the indoor ceiling, reduces the space occupied on the ground, and combines the characteristics of the elastic cable to achieve convenient charging operation.

[0020] (2) This utility model provides a charging pile, which uses a first bracket and a second bracket to eliminate the stress at the transition point of the elastic section of the cable, and keeps the movement path of the charging head close to the axis of the outer shell during the pulling down and retraction charging process, so as to prevent the charging head from colliding and getting stuck with the outer shell, which would lead to the problem of not being able to return to the original position. The first bracket and the second bracket, through the limiting groove and the opening, realize that the straight state of the cable and the elastic section are coaxial on the same outer diameter, ensuring that the centroid remains vertical, and there is no resistance when extending and retracting during use.

[0021] (3) This utility model provides a charging pile, which uses a simple and quick suspension mechanism to fix the entire charging pile. The suspension height of the charging pile can be adjusted according to the size of the indoor space. The hook-type installation method is convenient for efficient installation and promotion in existing underground garages and other scenarios.

[0022] (4) This utility model provides a charging pile with a spring-loaded component on the fixed frame, which can limit the return speed of the charging head and prevent it from colliding with the outer shell.

[0023] (5) This utility model provides a charging system that uses a suspension assembly to fix the charging pile, preventing the charging cable from falling to the ground, causing dirt and the risk of tripping pedestrians. This suspension method has the advantages of not being knocked down, not being soaked in water, and the cable not falling to the ground to ensure safety and surface cleanliness. In addition, the charging pile has a small overall size, does not require a special site for installation, and can be widely promoted and applied to traditional garages. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] Example 1

[0038] like Figure 1 and Figure 2As shown, the charging pile provided in this embodiment includes a circuit board and a telescopic mechanical assembly, an elastic spiral assembly and a coaxial charging head assembly connected sequentially from top to bottom. When the charging pile is not in use, all of the above assemblies are housed inside the housing 1. The upper part of the circuit board and telescopic mechanical assembly is mounted on the indoor ceiling via a suspension assembly. The suspension assembly can adjust the suspension position and suspension height of the other assemblies and the housing 1. The circuit board and telescopic mechanical assembly includes a fixing frame 2 and its internal structure. The elastic spiral assembly includes a cable 4 and its internal structure. The coaxial charging head assembly includes an axis retention structure located at the bottom of the fixing frame 2 and the top of the charging head 6 to maintain the coaxiality of the charging head 6 and the housing 1.

[0039] Specifically, the charging pile in this embodiment includes a cable 4 suspended from the indoor ceiling. The cable 4 passes downward through the fixing frame 2, the first bracket 3, and the second bracket 5 in sequence. The end of the cable 4 is electrically connected to the charging head 6. The structure through which the cable 4 passes is set inside the cylindrical outer shell 1 with openings at the top and bottom. The first bracket 3 is set at the bottom of the fixing frame 2. The section of the cable 4 between the first bracket 3 and the second bracket 5 is a spring-shaped elastic section 41, and the remaining sections are transition sections. The elastic section 41 is used to provide a rebound force after the charging head 6 is pulled down. After the user pulls the charging head 6 out of the charging vehicle, it returns to its original position and retracts into the outer shell 1 under the action of the rebound force. This can save indoor charging pile installation space and is convenient to use. The process of plugging and unplugging the charging head 6 can be completed with only one hand. In the non-working state, the elastic section 41 and the second bracket 5 are located inside the outer shell 1. In the working state, a part of the elastic section 41 and the second bracket 5 extend out from the outer shell 1.

[0040] Preferably, the charging head 6 has a pull cord hanging from it, which makes it convenient for users to pull the charging head 6 to charge new energy vehicles.

[0041] Furthermore, the section where the elastic segment 41 and the cable 4 are connected is defined as the transition segment. The transition segment includes a straight state and an arc state. The arc state gradually changes its curvature and smoothly transitions to the connecting elastic segment 41. The transition segment passes through the first bracket 3 and the second bracket 5. The section that passes through the first bracket 3 is the first transition segment, and the section that passes through the second bracket 5 is the second transition segment. The first bracket 3 and the second bracket 5 limit the transition segment to eliminate the stress that may cause the cable 4 to deviate from the central axis of the outer shell 1. The charging head 6 keeps moving along the central axis to prevent it from getting stuck at the bottom of the outer shell 1 or rubbing against the inner wall of the outer shell 1.

[0042] Furthermore, such as Figures 1-8As shown, a second limiting hole 26 is opened at the bottom of the fixing frame 2. The first bracket 3 is installed next to the second limiting hole 26 at the bottom of the fixing frame 2. After the first transition section passes through the second limiting hole 26, it gradually bends from its original straight shape to a spiral shape close to that of the elastic section 41. The first bracket 3 includes a fastening buckle 31 and a limiting groove 33. The inner surface of the limiting groove 33 is adapted to the surface of the elastic section 41, and the groove depth gradually decreases due to the pitch of the spiral, ensuring that the axis of the limiting groove 33 and the first transition section are as follows: Figure 4 The dotted line indicates the overlapping state. Multiple fasteners 31 are fastened and fixed at the opening of the limiting groove 33 in the first transition section. The fasteners 31 and the groove limit and fix the first transition section. Preferably, the fasteners 31 are fixed with bolts.

[0043] Furthermore, the second bracket 5 includes a first limiting block 51 and a second limiting block 52 fixedly installed along the fastening surface. After the two are fastened together, they form a spiral channel for the second transition section to pass through. The spiral channel is adapted to the shape of the second transition section. In order to facilitate the assembly of the second bracket 5, the spiral channel is set as a discontinuous first channel 53 and second channel 54. The above channels are all the same as the spiral radius of the second transition section and the outer diameter of the cable 4. After the second transition section passes through the first channel 53 and the second channel 54, it enters the charging head mounting hole 55 opened at the bottom of the second limiting block 52. The charging head 6 is fixed to the second bracket 5 through the charging head mounting hole 55. The second transition section of the cable 4 is electrically connected to the charging head 6 through the charging head mounting hole 55.

[0044] The working principle of the first bracket 3 and the second bracket 5 mentioned above is as follows: both are used to limit the transition section, so as to realize the smooth transition from the transition section of the cable 4 to the elastic section 41. Specifically, the first bracket 3 is used to eliminate the stress generated when the first transition section in the fixed frame 2 changes from a straight state to an elastic section 41, and the second bracket 5 is used to eliminate the stress generated when the second transition section changes from an arc state to a straight state and connects to the charging head 6. Although the shape design of the first bracket 3 and the second bracket 5 is different, the function of both is to eliminate the stress generated when the cable 4 changes from a spiral shape to a straight shape. It should be understood that the deformable structure designed using the above principle should all fall within the scope of this solution.

[0045] Furthermore, a pin 511 is provided at the bottom of the first limiting block 51, the pin 511 being perpendicular to the fastening surface. A pin groove 521 is provided on the second limiting block 52 at a position corresponding to the pin 511. Inserting the pin 511 into the pin groove 521 provides limiting, improving assembly efficiency. Preferably, for ease of assembly, the first limiting block 51 and the second limiting block 52 are fixedly connected by bolts. Furthermore, a buckle 512 is provided at the bottom of the pin 511, radially inward along the charging head mounting hole 55, for quick engagement of the charging head 6. The buckle 512 can be replaced by common fixing methods such as bolts or threaded connections.

[0047] Based on Example 1 and according to the working principles of the first support 3 and the second support 5, a modified structure 1 for both is proposed:

[0048] The spiral channel and the limiting groove 33 described in Example 1 can be replaced and applied.

[0049] Example 3

[0050] Based on Example 1, and according to the working principles of the first support 3 and the second support 5, a second modified structure for both is proposed:

[0051] The fastening buckle 31 is fixed by bolts or clips, and the fastening buckle 31 can be replaced by straps, tape, etc., to fix the transition section.

[0052] Example 4

[0053] Based on Example 1, and according to the working principles of the first support 3 and the second support 5, a third modified structure for both is proposed:

[0054] The limiting groove 33 in the first bracket 3 can be formed by splicing multiple continuous or discontinuous grooves. When using discontinuous grooves, fasteners should be designed on each groove to fix the transition section.

[0055] The first limiting block 51 and the second limiting block 52 can be connected left and right to form a spiral channel, and the two can be fixed by snap-fit ​​instead of bolts.

[0056] Example 5

[0057] Based on Embodiment 1, a spring-loaded component 25 is installed inside the fixing frame 2. A pull rope 251 is provided at the bottom of the spring-loaded component 25 to fix it to the charging head 6. During the spring-loaded process, the spring-loaded component 25 limits the spring-loaded speed of the charging head 6 to prevent it from colliding with or getting stuck in the outer shell 1. Further, a first wire hole 32 is provided at the center of the first bracket 3, and a second wire hole 513 is provided at the center of the first limiting block 51. The pull rope 251 passes through the first wire hole 32, the second wire hole 513 and the charging head mounting hole 55 from top to bottom, and is fixedly connected to the charging head 6. Both the spring-loaded component 25 and the elastic segment 41 provide spring-loaded force for the charging head 6.

[0058] Example 6

[0059] Based on embodiment 1 or 2, the fixing frame 2 includes a first mounting plate 21 and a second mounting plate 23 arranged in parallel, which are fixedly connected by a support column 22. The first bracket 3 is fixed to the bottom surface of the second mounting plate 23, and a circuit board 7 is provided inside the fixing frame 2 for controlling the circuit on and off.

[0060] Preferably, the first mounting plate 21 and the second mounting plate 23 adopt a hollow design, and the first bracket 3 and the second mounting plate 23 adopt insulating injection molded parts, which helps to reduce the overall weight of the fixing frame 2 and ensure safety.

The suspension mechanism 8 includes a hook 81 anchored or bolted to the indoor ceiling, and a fixedly connected hanging ring 82 and an adjusting collar 83. The adjusting collar 83 is detachably fixed to the cable 4, and the hanging ring 82 is fixed to the adjusting collar 83. The charging pile is fixed by suspending the hanging ring 82 to the hook 81. The adjusting collar 83 can be moved to different positions on the cable 4 to adjust the length of the hanging cable 4, so that the distance between the charging head 6 and the ground meets the relevant specifications, and it is also convenient to adjust the distance between the charging head 6 or the cable and the user according to the indoor ceiling height.

[0063] Example 8

Specifically, it is fixed to the fixing frame 2 and / or the first bracket 3 by means of bolts. There should be more than three sets of bolts and screw feet 11, and they should be evenly distributed around the axis of the outer shell 1.

[0065] Preferably, the inner diameter of the outer casing 1 can be appropriately enlarged to reduce friction between the cable 4 and the charging head 6 and its inner wall; patterns and lighting structures can be provided on the outer casing 1 to improve aesthetics and practicality. The circuit board 7 is electrically connected to an emergency stop button 9, which is located on the surface of an indoor wall or column and is used to stop the power supply in an emergency in dangerous situations.

[0066] The indoor spaces in the above embodiments 1-8 include various scenarios such as underground parking garages that provide charging functions for new energy vehicles and have ceilings.
