Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a small wall-mounted charging pile. Background Technology

[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings, residential parking lots, or charging stations. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. With the rapid growth of the number of new energy vehicles, traditional large charging piles occupy a lot of space and have limited installation. There is a particular need for small wall-mounted charging piles to flexibly utilize the wall space of residential and commercial buildings, realize convenient private charging, meet users' fragmented and instant charging needs, and alleviate the pressure of insufficient public charging facilities. Therefore, there is a particular need for a small wall-mounted charging pile.

[0003] Chinese patent CN222407979U, published on January 28, 2025, discloses a small wall-mounted charging pile. It uses an arc-shaped mesh plate at the bottom to filter the exhaust air, preventing external dust from seeping into the exhaust vents or clogging them. However, while the arc-shaped mesh plate can filter dust, it lacks a convenient disassembly and cleaning design. With increased use, the accumulated dust on the mesh plate severely affects the filtration effect and ventilation efficiency, thus weakening heat dissipation. Furthermore, improper user cleaning may damage the mesh plate or affect its sealing. Additionally, relying solely on a back support for installation makes it difficult to adapt to walls of varying thicknesses or complex installation environments, lacking adjustment functionality and failing to accommodate certain special installation scenarios, thus limiting the charging pile's application range.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a small wall-mounted charging pile, including a charging shell 1, a charging cover plate 2 installed on the surface of the charging shell 1, a heat dissipation box 3 connected to the top of the charging shell 1, an air filter plate 4 installed on the surface of the heat dissipation box 3, a side hanging bracket 5 installed on the upper side of the charging shell 1, a mounting column 6 connected to the back side of the charging shell 1, a detachable component 7 provided at the bottom of the charging shell 1, and a mounting component 8 provided between the back side of the charging shell 1 and the mounting column 6;

[0024] The detachable component 7 includes an arc-shaped mesh plate 701, which is installed on the bottom side of the charging housing 1. A mounting block 702 is connected to the side of the arc-shaped mesh plate 701. A mounting groove 703 is formed on the side of the charging housing 1. Threaded holes 704 are formed on the surfaces of both the mounting block 702 and the mounting groove 703. A screw 705 is threaded onto the inner wall of the threaded hole 704. A nut 706 is connected to the outer end of the screw 705. A fixing rod 707 is connected to the inner end of the nut 706. A guide block 708 is connected to the side of the fixing rod 707. A guide rod 709 is slidably connected to the outer side of the fixing rod 707. A guide groove 710 is formed on the inner side of the guide rod 709. A return spring 711 is connected to the outer side of rod 707 and guide rod 709. A cross-shaped retaining strip 712 is connected to the outer end of both guide rod 709 and return spring 711. A retaining groove 713 is provided on the surface of mounting block 702. Through the detachable component 7, when the arc-shaped mesh plate 701 needs to be disassembled and cleaned, the operator first manually rotates nut 706, causing screw 705 to exit outward along threaded hole 704, separating screw 705 from mounting block 702 and mounting groove 703. At this time, return spring 711 is in its initial compressed state, and its elastic potential energy pushes cross-shaped retaining strip 712 outward, causing fixed rod 707 to slide synchronously with cross-shaped retaining strip 712. The guide block 708 moves along the guide rod 709 within the guide groove 710, ensuring the smooth outward movement of the cross-shaped retaining strip 712 until it completely disengages from the slot 713. After releasing the engagement between the cross-shaped retaining strip 712 and the slot 713, the connection constraint between the arc-shaped mesh plate 701 and the charging housing 1 disappears. The operator can then directly remove the arc-shaped mesh plate 701 from the bottom of the charging housing 1 for cleaning. After cleaning, the arc-shaped mesh plate 701 is reinstalled onto the bottom of the charging housing 1, aligning the mounting block 702 with the mounting groove 703 for insertion. During insertion, the inclined surface of the cross-shaped retaining strip 712 first contacts the surface of the mounting block 702, and the mounting block 702 then engages with the cross-shaped retaining strip. 712 generates an inward thrust, forcing the cross-shaped retaining strip 712 to compress the return spring 711 and retract inward. When the mounting block 702 is fully inserted into the mounting groove 703 and the groove 713 corresponds to the position of the cross-shaped retaining strip 712, the elastic force of the return spring 711 pushes the cross-shaped retaining strip 712 to pop out quickly and lock into the groove 713, achieving the initial positioning of the arc-shaped mesh plate 701. Subsequently, the operator screws the screw 705 into the threaded hole 704 to further strengthen the connection stability between the mounting block 702 and the mounting groove 703, ensuring that the arc-shaped mesh plate 701 is firmly installed at the bottom of the charging housing 1, while ensuring its sealing performance to prevent dust from seeping into the interior of the charging housing 1 from the connection.

[0025] Furthermore, two identical sets of air filter plates 4 are installed on the surface of the heat dissipation box 3, and are symmetrically distributed on the front and rear sides of the heat dissipation box 3 with respect to the central axis of the heat dissipation box 3. Through the arrangement of the air filter plates 4, the two sets of air filter plates symmetrically distributed on the front and rear sides of the heat dissipation box 3 can simultaneously draw in outside air from two directions, greatly increasing the airflow and significantly improving the heat dissipation efficiency inside the charging shell 1. The symmetrical layout makes the airflow evenly distributed inside the heat dissipation box 3, avoiding local overheating and ensuring a balanced and stable temperature field inside the charging shell 1. At the same time, the filtering effect of the air filter plates 4 can effectively intercept external dust and particles, preventing them from entering the charging shell 1 with the airflow, avoiding dust accumulation on circuit boards and other electrical components, ensuring the normal operation of the heat dissipation system and electrical components, and extending the service life of the charging pile.

[0026] Furthermore, the arc-shaped mesh plate 701 is installed on the bottom inner side of the charging housing 1 via the mounting block 702 and the mounting groove 703. The outer wall size of the mounting block 702 matches the inner wall size of the mounting groove 703. Through the setting of the mounting block 702 and the mounting groove 703, the precise fit between the mounting block 702 and the mounting groove 703 provides accurate positioning and stable support for the arc-shaped mesh plate 701, ensuring that the installation position of the arc-shaped mesh plate 701 is accurate and effectively preventing it from shifting or shaking during use. The tight size fit forms a good sealing structure, which can prevent dust and moisture from seeping into the interior of the charging housing 1 from the installation gaps, enhancing the dustproof and moisture-proof performance of the charging pile. In addition, this design simplifies the installation process of the arc-shaped mesh plate 701. The operator only needs to align the mounting block 702 with the mounting groove 703 and insert it to complete the initial positioning, which facilitates the subsequent screw fixing, improves the work efficiency of disassembly and installation, and reduces the maintenance difficulty.

[0027] Furthermore, the guide rod 709 slides on the outside of the fixed rod 707 via the guide block 708 and the guide groove 710. The size of the guide block 708 is precisely matched with the size of the guide groove 710. Through the setting of the guide block 708 and the guide groove 710, the sliding cooperation of the guide block 708 in the guide groove 710 provides precise guidance for the telescopic movement of the cross clip 712, ensuring that the cross clip 712 maintains a straight movement trajectory during the pop-up and retraction process, avoiding tilting or jamming, and ensuring that the cross clip 712 can smoothly enter or exit the slot 713. The precisely matched size makes the gap between the guide block 708 and the guide groove 710 extremely small, effectively reducing shaking and friction during the movement, improving the stability and reliability of the movement of the cross clip 712. This guide structure can also enhance the connection strength between the cross clip 712 and the fixed rod 707, making it less prone to damage in frequent telescopic operations, extending the service life of the detachable component 7, and ensuring the stability of the connection between the arc-shaped mesh plate 701 and the charging shell 1.

[0028] Furthermore, the mounting assembly 8 includes a fixing plate 801, which is fixedly connected to the back side of the charging housing 1. The fixing plate 801 has an internal telescopic groove 802, and a compression spring 803 is connected to the inner end of the telescopic groove 802. The other end of the compression spring 803 is connected to a telescopic plate 804. A limit block 805 is connected to the side of the telescopic plate 804. A limit groove 806 is formed on the inner side of the telescopic groove 802. A clamping plate 807 is connected to the outer end of the telescopic plate 804. A positioning hole 808 is formed on the surface of the clamping plate 807. The outer side of the positioning hole 808... A telescopic spring 809 is connected to the other end of the telescopic spring 809, and a pull block 810 is connected to the inner end of the pull block 810. A mounting rod 811 is connected to the inner end of the pull block 810. A fixing hole 812 is opened on the surface of the mounting column 6. When installing a small wall-mounted charging pile, the mounting column 6 is first fixed to the wall or other installation positions. Then, the mounting assembly 8 is operated to pull the pull block 810 outward. The pull block 810 drives the mounting rod 811 to move outward against the elastic force of the telescopic spring 809, so that the mounting rod 811 retracts from the positioning hole 808. At this time, the clamping plate 807 is... In the adjustable state, the charging housing 1 is then brought close to the mounting post 6, aligning the clamping plate 807 with both sides of the mounting post 6. The pull block 810 is released, the telescopic spring 809 returns to its original position, and the mounting rod 811 is pushed into the fixing hole 812 on the surface of the mounting post 6, initially fixing the clamping plate 807 to the mounting post 6. During the process of the clamping plate 807 approaching the mounting post 6, if there is a positional deviation or external force, the telescopic plate 804 can slide within the telescopic groove 802. When the clamping plate 807 is subjected to pressure in the direction of the charging housing 1, the telescopic plate 804 compresses the compression spring 803 and extends. The telescopic plate 804 moves within the groove 802, and the limiting block 805 slides within the limiting groove 806, ensuring that the telescopic plate 804 moves smoothly and does not come out. When the pressure decreases, the compression spring 803 pushes the telescopic plate 804 to reset, so that the clamping plate 807 always fits tightly against the mounting column 6. Through the synergistic action of the compression spring 803 and the telescopic spring 809, the mounting component 8 can not only realize the rapid installation and fixation of the charging pile and the mounting column 6, but also adaptively adjust its position during the installation process to ensure stable installation. At the same time, it can also buffer external vibrations and other external forces to improve the stability of the charging pile after installation.

[0029] Furthermore, multiple sets of compression springs 803 are arranged at the inner end of the telescopic groove 802, and each set of compression springs 803 is evenly distributed. Through the arrangement of compression springs 803, multiple sets of equally distributed compression springs can provide uniform and stable elastic support force for the telescopic plate 804. During installation, when the clamping plate 807 is squeezed by external force, multiple sets of compression springs are compressed synchronously, effectively dispersing the force and avoiding local stress concentration that could lead to spring damage or deformation of the telescopic plate. During use, these springs can buffer the impact force generated by the vibration of the charging pile and external collision in real time, ensuring that the clamping plate 807 and the mounting column 6 always remain in close contact, enhancing the stability of the charging pile after installation. In addition, the multi-spring structure also improves the reliability and accuracy of the telescopic plate 804's reset, enabling it to quickly and smoothly return to its original position after the force is removed, ensuring the long-term stable operation of the installation component 8.

[0030] Furthermore, the telescopic plate 804 slides inside the telescopic groove 802 via the limiting block 805 and the limiting groove 806. The outer wall size of the limiting block 805 matches the inner wall size of the limiting groove 806. Through the setting of the limiting block 805 and the limiting groove 806, the precisely matched dimensions of the two provide precise guidance for the sliding of the telescopic plate 804, effectively limiting its radial displacement and ensuring that the telescopic plate 804 can only slide smoothly along the axial direction of the telescopic groove 802, avoiding tilting, jamming or disengagement during the telescopic process. This guiding structure greatly enhances the stability and reliability of the movement of the telescopic plate 804, allowing the elastic potential energy of the compression spring 803 to be effectively transferred to the clamping plate 807, ensuring the normal functioning of the buffering and adjustment functions of the installation component 8. At the same time, the tight fit can also reduce the sliding gap, reduce noise and wear caused by vibration, extend the service life of the installation component 8, and provide a reliable guarantee for the stable installation and use of the charging pile.

[0031] Working Principle: When the small wall-mounted charging pile is put into use, all components of the entire device work together to ensure safe and efficient charging. During the installation phase, the mounting column 6 is first fixed to the wall. Pulling the pull block 810 of the mounting component 8 retracts the mounting rod 811. After adjusting the position of the clamping plate 807, the pull block is released. The telescopic spring 809 pushes the mounting rod 811 into the fixing hole 812 of the mounting column 6 to achieve initial fixation. If external force or positional deviation occurs during the installation process, the telescopic plate 804 slides in the telescopic groove 802 under the action of the compression spring 803. The limiting block 805 and the limiting groove 806 cooperate to guide and ensure that the clamping plate 807 fits tightly against the mounting column 6, completing a stable installation. During operation, the symmetrical air filter plates 4 on the surface of the heat dissipation box 3 draw in outside air from the front and rear sides, filter dust, and accelerate the air circulation inside the charging shell 1, reducing the internal temperature. To maintain the normal operating temperature of electrical components, during charging, if dust accumulation affects heat dissipation, the detachable component 7 comes into play. Rotating the nut 706 causes the screw 705 to disengage, and the return spring 711 pushes the cross-shaped retaining strip 712 out of the slot 713, allowing the arc-shaped mesh plate 701 to be removed for cleaning. After cleaning, during installation, the mounting block 702 and the mounting slot 703 are precisely positioned. The cross-shaped retaining strip 712 is compressed and then pops out to engage. Tightening the screw further reinforces the system and prevents dust and moisture from seeping in. In daily use, multiple sets of compression springs 803 continuously buffer the vibration and external force of the charging pile, while the limiting block 805 and the limiting slot 806 ensure the stable sliding of the telescopic plate 804, ensuring that the charging pile is always securely installed. All components work together to achieve efficient heat dissipation, convenient maintenance, and safe charging. This completes the usage process of a small wall-mounted charging pile.
