Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and more specifically, to a dual-pole charging pile suspension bracket. Background Technology

[0002] As an important component of new energy transportation, the installation stability of charging piles, the supporting infrastructure for electric vehicles, directly affects the user experience. When charging spaces are not adjacent to walls or pillars, traditional solutions often employ a single-pole suspension bracket structure.

[0003] For example, the charging pile adjustment frame disclosed in Chinese patent CN220129975U and the suspension bracket disclosed in CN223173971U both suffer from inherent structural defects of single-rod support: First, the single-rod structure has weak resistance to lateral forces, making it prone to continuous vibration under vehicle movement or external forces; second, existing rod connection methods mostly use sliding sleeves with bolt locking, and this rigid connection method cannot effectively absorb vibration energy, but instead amplifies the swaying amplitude. More significantly, existing brackets have obvious shortcomings in transportation and installation; the rod components are inconvenient to store and transport, and difficult to assemble quickly and accurately on-site, significantly increasing the user's installation time and costs. To address these issues, existing technologies urgently need improvement. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems mentioned in the background art above, and then to propose a double-pole charging pile suspension bracket.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A dual-pole charging pile suspension bracket includes two parallel vertical pole groups. Each vertical pole group is formed by connecting several vertical sub-tubes end to end. A connecting member is slidably fitted on each vertical pole group. A charging pile is fixedly connected to each of the two connecting members. Each vertical sub-tube includes a tube body. External threaded connecting pipes and internal threaded connecting pipes are respectively provided on both sides of the tube body. Adjacent vertical sub-tubes are connected together through external threaded connecting pipes and internal threaded connecting pipes. A positioning hole is formed on the tube body.

[0007] Furthermore, a top flange is fixedly connected to the top of the vertical rod assembly, and a bottom flange is provided at the bottom of the vertical rod assembly. The top flange is fixedly connected to the basement ceiling by expansion bolts, and the bottom flange is fixedly connected to the basement floor by expansion bolts.

[0008] Furthermore, the connecting member includes a sliding sleeve that can slide up and down along the outer wall of the vertical sub-tube. A fastening knob is threaded onto the sliding sleeve. The vertical sub-tube is provided with several positioning holes. The fastening knob can be inserted into the positioning holes to restrict the relative movement of the sliding sleeve on the vertical sub-tube.

[0009] Furthermore, a rubber layer is formed on the inner wall of the positioning hole, and the fastening knob is threaded into the positioning hole, causing the rubber layer to undergo elastic deformation.

[0010] Furthermore, a connecting plate is fixedly connected to the sliding sleeve, and the connecting plate is fixedly connected to the back of the charging pile by bolts.

[0011] Furthermore, two limiting plates are formed on the inner wall of the tube, and through holes are provided on the limiting plates. A connecting member is provided between adjacent tubes, and the connecting member includes a connecting rope. The two ends of the connecting rope pass through the through holes of the two tubes respectively to form an anti-detachment plate.

[0012] Furthermore, the connecting component includes a sliding sleeve that can slide up and down along the outer wall of the vertical sub-tube. A fixed block is formed on the outer side of the sliding sleeve, and a mounting hole is formed in the middle of the fixed block. Sliding grooves are provided on both sides of the mounting hole. A moving block is slidably fitted in the sliding groove. A plug-in plate is installed on the moving block. A flexible spring is provided between the left side of the sliding groove and the moving block. A rectangular through hole is provided on the sliding sleeve to accommodate the plug-in plate. A fastening knob is threaded into the mounting hole. A rack is fixedly connected to the outer wall of the vertical sub-tube by bolts. The rack is located at the rectangular through hole.

[0013] Furthermore, the flexible spring can drive the plug plate through the rectangular through hole and insert it into the rack.

[0014] Furthermore, when the plug plate is inserted into the rack, the end of the fastening knob abuts against the surface of the moving block.

[0015] Furthermore, the teeth of the rack are angled upwards.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This utility model enhances the resistance to lateral forces through a double-rod structure, and combines a bendable and retractable vertical sub-tube with a quick connection design, which solves the problems of poor stability and complicated installation of traditional single-rod supports.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0023] In existing technologies, electric vehicle charging station installations often face the challenge of parking spaces being far from walls or pillars. Traditional single-pole suspension brackets suffer from insufficient structural stability, making them prone to vibrations caused by external forces or the equipment's own weight, thus affecting the long-term reliability of the charging station. Existing technologies employ sliding sleeve joints with bolt locking, which are prone to loosening under dynamic loads, exacerbating the shaking and creating safety hazards after installation.

[0024] To address these issues, researchers discovered inherent limitations in the torsional and lateral force resistance of single-pole structures and attempted to improve overall stability by increasing the number of support points. Further analysis revealed that a parallel arrangement of two poles could create a symmetrical support structure, but this required resolving the issues of adjusting pole height and synchronizing the movement of connectors. Therefore, the design approach shifted to a modular pole assembly method, achieving a balance between ease of transport and installation flexibility through detachable connections.

[0025] like Figures 1-5 As shown, a dual-pole charging pile suspension bracket includes two parallel vertical pole groups 1. Each vertical pole group is formed by connecting several vertical sub-tubes 11 end to end. A connecting member is slidably fitted on each vertical pole group, and a charging pile 100 is fixedly connected to the two connecting members.

[0026] The vertical rod assembly refers to an expandable support structure formed by connecting multiple vertical sub-tubes through end threads. Specifically, it can be quickly assembled using a combination of externally and internally threaded connecting pipes, facilitating adjustment of the number of sub-tubes according to installation height requirements. The connecting component refers to a sleeve assembly that can slide along the outer wall of the vertical sub-tube. Specifically, it can be implemented using a sliding sleeve structure with a fastening knob. The knob locks in position through the engagement of the positioning hole, ensuring the charging pile remains stable after installation.

[0027] Furthermore, a top flange 13 is fixedly connected to the top of the vertical rod assembly, and a bottom flange 12 is provided at the bottom of the vertical rod assembly. The top flange is fixedly connected to the basement ceiling by expansion bolts, and the bottom flange is fixedly connected to the basement floor by expansion bolts.

[0028] The top and bottom flanges refer to the fixed bases respectively installed at both ends of the rod assembly. Specifically, they can be ring-shaped metal plate structures with bolt holes, rigidly connected to the building structure via expansion bolts to form a two-way fixed support. The top flange can be made of Q235 steel plate with a thickness of 5-8mm and a diameter of 150-200mm, used to rigidly connect the top of the support to the building structure. The bottom flange can be made of the same material and processing technology as the top flange, used to provide stable support between the bottom of the support and the ground. The expansion bolts are fasteners with expansion sleeves, specifically high-strength alloy steel bolts of M12-M16 specifications. They are anchored by radial expansion force generated after being drilled and implanted into the concrete structure.

[0029] Specifically, two vertical rod assemblies are fixed parallel to each other between the ceiling and the ground, forming a stable support frame through a rigid connection of flanges. The vertical sub-tubes are modularly expandable via threaded connections at the ends, allowing users to add or remove sub-tubes according to actual installation height requirements. After the connecting component slides along the outer wall of the vertical sub-tube to the target position, it is locked by inserting a knob into the positioning hole, thus fixing the charging pile to the symmetrical support points of the dual-rod structure. This structure utilizes a dual-rod layout to distribute the load, reducing the risk of stress concentration at a single point, while the sliding connector design allows for flexible adjustment of the charging pile height.

[0030] Compared to existing technologies, traditional single-pole supports rely on a single support point to bear the weight of the charging pile, making them prone to swaying due to torque. This solution uses a symmetrical double-pole layout to form a stable spatial support structure, significantly improving resistance to lateral forces. Simultaneously, the modular sub-tube design replaces the traditional integral pole, facilitating folding and storage during transportation and enabling rapid assembly during installation, avoiding the fitting gap issues caused by sliding joints in existing technologies.

[0031] Through the above technical solution, this application effectively solves the vibration problem caused by insufficient stability of single-pole supports. The double-pole structure enhances overall rigidity and reduces the vibration amplitude during charging pile operation. The combination design of modular sub-tubes and adjustable connectors allows the support to adapt to different floor heights while maintaining ease of installation. The bidirectional flange fixing method further improves the connection strength between the support and the building structure, preventing displacement during long-term use.

[0032] Furthermore, such as Figure 2As shown, the connecting component includes a sliding sleeve 201, which can slide up and down along the outer wall of the vertical sub-tube. A fastening knob 204 is threaded onto the sliding sleeve. In cooperation with this, the vertical sub-tube is provided with a plurality of positioning holes 205. The fastening knob can be inserted into the positioning holes to restrict the relative movement of the sliding sleeve on the vertical sub-tube.

[0033] The sliding sleeve is an annular component fitted onto the outside of the vertical sub-tube. It can be made of metal or engineering plastic, with an inner diameter slightly larger than the outer diameter of the vertical sub-tube to achieve a sliding fit. It supports the weight of the charging pile and adjusts the installation height. The fastening knob is a threaded bolt component, typically made of stainless steel. It is screwed into a threaded hole on the side wall of the sliding sleeve, forming a mechanical limit after insertion into the positioning hole. The positioning holes are through holes spaced apart along the axial direction of the vertical sub-tube. They can be evenly distributed on the surface of the vertical sub-tube, providing multiple fixing positions to accommodate different installation height requirements. The rubber layer is an elastic material layer attached to the inner wall of the positioning holes. It can be made of silicone rubber or nitrile rubber. When the fastening knob is screwed in, it undergoes elastic deformation to increase frictional resistance and prevent accidental loosening of the fastening knob.

[0034] Specifically, after the sliding sleeve is fitted onto the outer wall of the vertical sub-tube, it can slide up and down axially to the target height. The fastening knob is screwed into the threaded hole on the side wall of the sliding sleeve. When the end of the knob is aligned with the positioning hole on the vertical sub-tube, continuing to screw it in will insert the front end of the knob into the positioning hole. At this time, the rubber layer is compressed and expands radially, which not only fills the assembly gap between the knob and the positioning hole, but also generates a continuous clamping force through elastic deformation.

[0035] Compared to existing technologies, current single-rod supports use a sliding sleeve directly bolted to the rod body, which suffers from small contact area and insufficient clamping force, making the bolts prone to loosening due to vibration. This solution, by setting positioning holes with rubber layers in the vertical sub-tube, creates a three-dimensional constraint after the fastening knob is inserted. This eliminates axial sliding freedom and absorbs vibration energy through the elastic material, significantly improving the stability of the fixation.

[0036] In a more detailed design, a rubber layer is formed on the inner wall of the positioning hole, and the fastening knob is threaded into the positioning hole, causing the rubber layer to undergo elastic deformation.

[0037] The rubber layer refers to the elastic material layer covering the inner wall of the positioning hole, which can be made of vulcanized rubber or silicone, with a thickness of 0.5-2 mm. Its elastic deformation increases the contact friction with the fastening knob. Threaded insertion refers to the threaded structure on the outer surface of the fastening knob, which is inserted into the positioning hole by rotation. Standard metric threads or self-tapping threads can be used, with a thread depth of 5-15 mm. The thread engagement generates axial clamping force. Elastic deformation refers to the volume compression or radial expansion of the rubber layer under the pressure of the fastening knob. This can be achieved through the Poisson's ratio characteristic of the rubber material, with a deformation of 10%-30% of the original thickness. The rebound force generated by the deformation enhances the fixing stability.

[0038] Furthermore, a connecting plate 202 is fixedly connected to the sliding sleeve, and the connecting plate is fixedly connected to the back of the charging pile by bolts 203. The connecting plate is a rigid transition component used to bear the load of the charging pile, and can be made of stamped metal sheet. Its planar extension structure can distribute the force and increase the contact area with the sliding sleeve.

[0039] In at least one embodiment, the vertical sub-tube includes a tube body 111, with an external threaded connecting tube 112 and an internal threaded connecting tube 113 respectively provided on both sides of the tube body. Adjacent vertical sub-tubes are connected together through the external threaded connecting tube and the internal threaded connecting tube, and a positioning hole is formed on the tube body.

[0040] The externally threaded connecting pipe refers to a protruding structure with external threads located at the end of the pipe body. This can be achieved by using a metal sleeve coaxially welded to the pipe body, used to form a threaded fit with the internally threaded connecting pipe of the adjacent sub-pipe. The internally threaded connecting pipe refers to a grooved structure with internal threads located at the end of the pipe body. This can be achieved by using a metal collar nested coaxially with the pipe body, used to form a threaded fit with the externally threaded connecting pipe of the adjacent sub-pipe.

[0041] Furthermore, two limiting plates 114 are formed on the inner wall of the tube, and through holes 115 are provided on the limiting plates. A connecting member is provided between adjacent tubes, and the connecting member includes a connecting rope 117. The two ends of the connecting rope pass through the through holes of the two tubes respectively to form an anti-detachment plate 116.

[0042] The limiting plate is a plate-like structure installed on the inner wall of the tube, which can be achieved by welding or integral molding, and is used to limit the axial displacement of the connecting parts. The through hole is a through-hole that passes through the limiting plate, which can be achieved by drilling, and is used for the connecting rope to pass through to achieve a flexible connection between adjacent tubes. The anti-detachment plate is an enlarged structure formed at the end of the connecting rope, which can be achieved by thermoforming or injection molding, and is used to prevent the connecting rope from coming out of the through hole. The connecting part is a flexible connection structure composed of the connecting rope and the anti-detachment plate, which can be made of nylon rope or steel wire rope, allowing the vertical sub-tube to be bent and stored during transportation.

[0043] Specifically, the vertical sub-tubes are rigidly connected to the internally threaded connecting tubes via external threaded connectors, while maintaining overall continuity through flexible connectors. During transportation, the vertical sub-tubes can be bent and folded along the connectors, reducing packaging volume. During installation, users only need to screw the externally threaded connecting tubes of adjacent tubes into the internally threaded connecting tubes; there is no need to consider the tube order or pairing. A limiting plate constrains the movement path of the connecting rope through a through hole, while an anti-detachment plate ensures that the connecting rope remains connected to the tube body at all times.

[0044] Compared to existing technologies, current brackets, which use sliding joints and bolt locking, result in significant swaying of the components and require disassembly into multiple independent parts during transportation, increasing assembly complexity. This solution maintains the integrity of the components through flexible connectors, achieving both folding functionality for transportation and ensuring structural stability after installation through threaded connections, thus avoiding the risk of parts loss associated with traditional modular transportation.

[0045] Through the above technical solution, this application solves the problems of traditional brackets being too bulky during transportation and requiring manual matching of tubes during installation. The flexible connectors ensure that the vertical sub-tubes remain continuous and foldable during transportation, while the threaded connection structure allows for quick assembly without needing to distinguish the order of the tubes during installation, significantly reducing the user's assembly error rate and operation time.

[0046] In at least one embodiment, such as Figure 4 and Figure 5 As shown, the connecting component includes a sliding sleeve 201, which can slide up and down along the outer wall of the vertical sub-tube. A fixing block 31 is formed on the outer side of the sliding sleeve, and an installation hole 32 is formed in the middle of the fixing block. Sliding grooves 33 are provided on both sides of the installation hole. A moving block 34 is slidably fitted in the sliding groove. A plug-in plate 35 is installed on the moving block. A flexible spring 36 is provided between the left side of the sliding groove and the moving block. Correspondingly, a rectangular through hole 351 is provided on the sliding sleeve to accommodate the plug-in plate. A fastening knob 204 is threaded into the installation hole. Correspondingly, a rack 37 is fixedly connected to the outer wall of the vertical sub-tube by bolts. The rack is located at the rectangular through hole.

[0047] The flexible spring refers to a mechanical component with elastic restoring force, specifically a helical spring, used to push the insert plate to maintain its inserted position with the rack when no external force is applied. The rack is a strip-shaped component with a continuous toothed structure, specifically made of metal, and its upward-sloping tooth design creates a one-way self-locking structure. The insert plate is a plate-shaped component with a toothed meshing surface, specifically manufactured using a stamping process, and achieves positioning and locking of the sliding sleeve through meshing with the rack.

[0048] Specifically, when the fastening knob is screwed into the mounting hole, its end pushes the moving block to the left along the sliding groove, compressing the flexible spring. The connector plate moves synchronously with the moving block, inserting into the tooth gap of the rack, thus locking the sliding sleeve. When height adjustment is needed, the fastening knob is rotated in the opposite direction, the flexible spring pushes the moving block back to its original position, moving the connector plate away from the rack, thus resolving the locking of the sliding sleeve. The downward-sloping design of the rack teeth ensures that when the charging pile experiences a downward force under gravity, the meshing surface of the connector plate and the rack forms a self-locking mechanism, preventing accidental slippage.

[0049] Furthermore, the flexible spring can drive the moving plate to move away from the rack.

[0050] Furthermore, when the plug plate is inserted into the rack, the end of the fastening knob abuts against the surface of the moving block.

[0051] Furthermore, the teeth of the rack are angled downwards, so that after the plug plate is inserted into the rack, the charging pile can achieve self-locking under its own gravity.

[0052] The downward-sloping teeth of the rack refer to the downward-sloping tooth structure on the rack surface, which can be achieved by machining or stamping continuous oblique teeth on the metal strip surface. This structure allows the connector plate to engage with the rack in one direction under gravity, preventing reverse slippage. The end of the fastening knob abutting against the surface of the moving block means that after the knob is screwed into the mounting hole, its end contacts the moving block, creating pressure. This contact pressure can be controlled by adjusting the depth of the knob's insertion, thus keeping the moving block in a fixed position.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
