Description

Technical Field

[0001] The utility model relates to the field of anti-collision power supplies, in particular to an anti-collision type power supply. Background Art

[0002] Power supply, as an important device in life, is used in daily life and work, especially in some engineering construction or large equipment, where a large number of power supply devices are used. In order to prevent the power supply from being dented and damaged when it is hit by the outside world, causing the electronic components inside to be squeezed and collided and damaged, an anti-collision structure is generally set on the outside of the power supply shell for protection.

[0003] After searching, Chinese patent announcement number: CN219019201U discloses a power supply with anti-collision function, including an elastically deformable curved plate that can transfer a large amount of impact force when hit. At the same time, a buffer pad can avoid direct contact between the curved plate and the power supply shell, greatly improving the anti-collision ability of the power supply shell and increasing the service life of the power supply shell.

[0004] However, during actual use of the above-mentioned power supply, when a large-area curved plate and a buffer pad are set on the upper surface of the power supply shell for buffering protection, the upper surface of the power supply shell will be blocked by a large area, so that the heat generated by the electronic components inside the power supply shell during operation cannot be dissipated in time when it is transferred to the upper surface of the power supply shell, and accumulates in the gap between the power supply shell and the curved plate and the buffer pad, resulting in heat accumulation, which affects the timely heat dissipation of the power supply. Therefore, an anti-collision power supply is proposed to solve the above problem. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 2The utility model provides an embodiment: an anti-collision power supply, including a power supply shell 1, a wiring mounting plate 2 is fixedly connected to the right surface of the power supply shell 1, a wiring head is fixedly connected to the right surface of the wiring mounting plate 2, which can be used to connect to external wires, a heat dissipation port 3 is opened on the rear side of the right surface of the power supply shell 1, a protective net is fixedly connected to the right side of the heat dissipation port 3, the protective net can protect the outside of the heat dissipation port 3 to prevent impurities from entering the interior of the power supply shell 1, and a heat dissipation groove 4 is opened on the upper surface of the power supply shell 1.

[0033] Reference Figure 3-Figure 5 , a heat dissipation component is provided inside the heat dissipation groove 4, and the heat dissipation component includes a heat conducting plate 51, which is plugged into the inside of the heat dissipation groove 4. The heat conducting plate 51 can absorb the heat emitted from the electrical components inside the power supply housing 1, and the heat conducting plate 51 is embedded in the inner wall of the power supply housing 1 through the heat dissipation groove 4, so that the five surfaces of the heat conducting plate 51 except the upper surface can contact with the power supply housing 1, further enhancing the heat transfer effect, and a telescopic rod 52 is fixedly connected to the upper surface of the heat conducting plate 51. The upper surface of the telescopic rod 52 is in contact with the bottom surface of the arc-shaped elastic sheet 6, and the heat absorbed by the heat conducting plate 51 can be transferred to the arc-shaped elastic sheet 6 through the telescopic rod 52 for heat dissipation, avoiding the setting of structures such as buffer pads and arc plates, which causes the upper surface of the power supply housing 1 to be blocked by a large area, so that the heat on the upper surface of the power supply housing 1 cannot be quickly dissipated, which affects the heat dissipation of the electrical components, and the telescopic rod 52 is fixedly connected to the upper surface of the heat conducting plate 51. The inner bottom surface of the retractable rod 52 is fixedly connected with a spring 53, and the upper end of the spring 53 is fixedly connected to the inner top surface of the telescopic rod 52. An arc-shaped elastic piece 6 is provided above the heat dissipation groove 4. In the initial state, the spring 53 can support the telescopic rod 52, so that the telescopic rod 52 is in a stretched state. When the arc-shaped elastic piece 6 is pressed downward and elastically deforms to offset the buffering, it will squeeze the telescopic rod 52, causing the spring 53 to compress and generate elastic potential energy. When the squeezing force disappears, the arc-shaped elastic piece 6 recovers its deformation, and the telescopic rod 52 can be reset under the action of the elastic potential energy of the spring 53, maintaining contact with the ground of the arc-shaped elastic piece 6 to avoid obstruction to the deformation of the arc-shaped elastic piece 6. Fine slots 7 are provided on the upper surface of the arc-shaped elastic piece 6. The fine slots 7 can reduce the amount of material used, while increasing the surface area of the arc-shaped elastic piece 6, further improving the heat dissipation effect.

[0034] A fixing box 8 is provided at both the front and rear ends of the arc-shaped elastic piece 6. The bottom surface of the fixing box 8 is fixedly connected to the upper surface of the power supply housing 1. A connecting component is provided inside the fixing box 8. The connecting component includes a limit plate 81. The limit plate 81 is slidably connected to the inside of the fixing box 8. The limit plate 81 can perform linear motion in the front and rear directions inside the fixing box 8. A connecting rod 82 is hinged on the side surface of the limit plate 81 close to the arc-shaped elastic piece 6. The end of the connecting rod 82 away from the limit plate 81 passes through the fixing box 8. The end of the connecting rod 82 away from the limit plate 81 is fixedly connected to the arc-shaped elastic piece 6. The volume of the connecting rod 82 is smaller than the limit plate 81. The limit plate 81 can limit the connecting rod 82 to prevent the connecting rod 82 from escaping from the inside of the fixing box 8, causing the end of the arc-shaped elastic piece 6 to lose its limit.

[0035] When the arc-shaped elastic piece 6 is pressed downward and elastically deformed, the front and rear ends of the arc-shaped elastic piece 6 will move toward the inside of the fixed box 8, and at the same time drive the connecting rod 82 to rotate, thereby ensuring the stability of the connection with the limiting plate 81, and preventing the arc-shaped elastic piece 6 from being directly fixedly connected to the surface of the limiting plate 81. When the arc-shaped elastic piece 6 is deformed, torsional fracture occurs at the connection with the limiting plate 81, and at the same time, the limiting plate 81 can move toward the inside of the fixed box 8, thereby expanding the deformation range of the arc-shaped elastic piece 6 and further enhancing the buffering and protection effect.

[0036] Reference Figure 3-Figure 4 The fixing box 8 is provided with an air vent 9 on the side surface away from the arc-shaped elastic sheet 6. The air vent 9 runs through the fixing box 8, and the air vent 9 is used to keep the interior of the fixing box 8 connected to the outside air, so as to avoid the fixing box 8 being in a closed state. As a result, when the limit plate 81 moves inside the fixing box 8, it is necessary to overcome the pressure generated by the compressed air. The left and right inner wall surfaces of the fixing box 8 are provided with a slide groove 10. The interior of the slide groove 10 is slidably connected with a slider 11. The outer wall of the slider 11 is fixedly connected to the outer wall of the limit plate 81. The slider 11 can perform a linear movement in the forward and backward directions inside the slide groove 10. The cooperation between the slide groove 10 and the slider 11 can guide and limit the movement of the limit plate 81, so that the limit plate 81 can only perform a stable forward and backward linear movement inside the fixing box 8, avoiding the limit plate 81 from deviating and getting stuck inside the fixing box 8 and being unable to move.

[0037] Working principle: When the top of the power supply shell 1 is hit by an external object, the arc-shaped elastic sheet 6 will be squeezed, causing the arc-shaped elastic sheet 6 to undergo elastic deformation downward to generate elastic potential energy, thereby buffering and offsetting the impact force. At the same time, the front and rear ends of the arc-shaped elastic sheet 6 will drive the limit plate 81 to move inside the fixed box 8 through the connecting rod 82, thereby avoiding obstruction to the deformation of the arc-shaped elastic sheet 6. After the impact force disappears, the arc-shaped elastic sheet 6 will restore its deformation and can perform the next buffering protection, which is convenient to use. When the electrical components inside the power supply shell 1 generate heat when working and are transferred to the power supply shell 1, the heat conducting plate 51 can absorb the heat on the upper surface of the power supply shell 1 and transfer it to the arc-shaped elastic sheet 6 through the telescopic rod 52, and dissipate heat through the surface of the arc-shaped elastic sheet 6, thereby avoiding the need to set arc plates, buffer pads and other structures above the power supply shell 1 for protective treatment, resulting in the upper surface of the power supply shell 1 being blocked by a large area, thereby affecting the heat dissipation effect.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
