Description
Technical Field
[0001] The utility model relates to the technical field of mobile power supplies, and particularly relates to a protection device for a mobile power supply. Background Art
[0002] With the rapid development of technology, portable mobile power supplies have become one of the indispensable electronic devices in modern people's daily lives, and are widely used in the charging needs of various portable electronic products such as mobile phones, tablet computers, cameras, etc. In order to meet the usage needs of users in different scenarios, especially the high power consumption situation during outdoor or long-term use, portable mobile power supplies often incorporate inverters to convert direct current into alternating current to power more types of devices. However, during the operation of the inverter, a large amount of heat is generated. If not dissipated in time, it will not only affect the device performance, but may also cause damage to internal components, and even lead to safety accidents.
[0003] Currently in the market, when solving the heat dissipation problem of the inverter for mainstream portable mobile power supplies, a passive heat dissipation method of opening a fan port on the housing and installing a fan is generally adopted. This design can indeed effectively improve the heat dissipation efficiency and ensure the stable operation of the inverter. However, the subsequent problem is that the opening of the fan port makes the mobile power supply have significant defects in terms of waterproof and dustproof. When used outdoors or in a humid environment, dust, water vapor, etc. are likely to invade the interior of the mobile power supply through the fan port, resulting in serious consequences such as circuit board short circuits and component corrosion, seriously affecting the device life and user safety.
[0004] To address the above problems, the traditional approach is to add an independent cover at the fan port, which needs to be manually opened by the user before use to allow the fan to discharge the high-temperature airflow. However, this design exposes many inconveniences in actual applications: First, users are prone to forgetting to open the cover, especially in emergency use or in a hurry, resulting in the mobile power supply operating in an overheated state, posing a safety hazard; Second, for the purpose of waterproof and dustproof, cover pieces also need to be set at the interfaces. Users need to open and close multiple cover pieces, which not only increases the operation burden but may also cause the cover pieces to be lost; Finally, the design of the independent cover piece often fails to achieve a perfect integration with the overall appearance of the mobile power supply, affecting the aesthetics.
[0005] In view of the above deficiencies of the prior art, there is a need for a device that can effectively solve the contradiction between power supply heat dissipation and waterproof and dustproof, while simplifying user operations and enhancing the user experience. Summary of the Utility Model
[0006] The utility model provides a protection device for a mobile power supply, which can automatically expose the heat dissipation port during use, improving the convenience and safety of device operation.
[0007] To solve the above technical problems, the present application provides the following technical solutions:
[0008] A protection device for a mobile power supply, including a mobile power supply body and a closed cover;
[0009] The mobile power supply body includes a top cover, a bottom shell and a circumferential panel;
[0010] The top cover is fixed on the top of the circumferential panel, and the bottom shell is fixed on the bottom of the circumferential panel; the joints between the top cover and the circumferential panel, and between the bottom shell and the circumferential panel, both protrude from the circumferential panel;
[0011] On the upper side or the lower side of the circumferential panel, there are interfaces and heat dissipation ports;
[0012] The closed cover circumferentially surrounds the circumferential panel and is slidably connected to the circumferential panel, sliding up and down along the circumferential panel. When the closed cover is located on the side where the interfaces and heat dissipation ports are located, it can cover the interfaces and heat dissipation ports.
[0013] The principle and beneficial effects of the basic solution are as follows:
[0014] In this solution, through an integrated closed cover and sliding mechanism, when not in use, the closed cover is used to block the interfaces and heat dissipation ports, providing comprehensive protection for the exposed ports of the mobile power supply, enabling the mobile power supply to have excellent waterproof and dustproof capabilities. The interfaces and heat dissipation ports are set on the same side. When in use, the heat dissipation ports and interfaces will be exposed simultaneously, avoiding the situation where the heat dissipation port is forgotten to be opened when the interface is opened, effectively solving the contradictory problem that setting a cover is likely to cause poor heat dissipation and not setting a cover is likely to cause interface contamination. It can automatically adapt to the heat dissipation requirements without additional operation by the user, ensuring the safe and stable operation of the device, and improving the convenience, safety, and user experience of device operation.
[0015] Furthermore, the circumferential panel includes a front panel, a rear panel, a left panel and a right panel; if there are interfaces on the upper side of the front panel, and there are heat dissipation ports on the upper sides of the left panel and the right panel; the heat dissipation ports and interfaces are on the same horizontal plane.
[0016] It can ensure that the closed cover can cover the heat dissipation ports and interfaces simultaneously, and also open the heat dissipation ports and interfaces simultaneously.
[0017] Furthermore, the height of the closed cover is 1 / 2 of the height of the front panel.
[0018] While ensuring that the closed cover can cover and open the heat dissipation ports and interfaces simultaneously, it increases the coverage area of the closed cover and improves the protection ability.
[0019] Furthermore, on the left and right sides of the front panel, and on the left and right sides of the rear panel, guiding grooves are longitudinally provided, and the guiding grooves extend from the top to the bottom of the front panel and the rear panel;
[0020] On the inner side of the closing cover, guide bars corresponding to the guide grooves are longitudinally arranged, and the guide bars are embedded in the guide grooves.
[0021] Make the sliding of the closing cover smoother.
[0022] Furthermore, symmetrical notches are formed on both sides of the upper part and both sides of the lower part of the guide groove; protrusions are formed on both sides of the upper part of the guide bar. When the closing cover slides upward to the maximum height, the protrusions can be embedded in the upper notches. When the closing cover slides downward to the lowest height, the protrusions can be embedded in the lower notches.
[0023] Through the cooperation of the protrusions and the notches, the opening and closing states of the closing cover are temporarily fixed.
[0024] Furthermore, magnets are fixed on the upper part and the inner side of the lower part of the rear panel; an embedding groove is formed on the inner surface of the closing cover, and iron-attracting metal is fixed in the embedding groove.
[0025] When the closing cover slides upward to the maximum height, the upper magnet can adsorb the iron-attracting metal. When the closing cover slides downward to the lowest height, the lower magnet can adsorb the iron-attracting metal.
[0026] Compared with the protrusions and the notches, using magnets for fixation can reduce the friction between the guide bar and the guide groove, and it is smoother when sliding in the intermediate state.
[0027] Furthermore, a number of anti-slip textures are provided on the outer surface of the closing cover.
[0028] It can increase the friction between the hand and the outer surface of the closing cover, facilitating the user to slide the closing cover.
[0029] Furthermore, a handle is fixed on the top of the top cover. Description of the Drawings

[0033] The following is a more detailed description through specific embodiments:
[0034] The markings in the attached drawings of the specification include: the closed cover 1, the top cover 2, the bottom shell 3, the interface 4, the heat dissipation port 5, the front panel 6, the right panel 7, the guide groove 8, the guide bar 9, the protrusion 10, and the handle 11.
[0035] Embodiment 1
[0036] As Figure 1 shown, a mobile power protection device in this embodiment includes a mobile power body and a closed cover 1;
[0037] The mobile power body includes a top cover 2, a bottom shell 3, and a circumferential panel;
[0038] The top cover 2 is fixed to the top of the circumferential panel, and the bottom shell 3 is fixed to the bottom of the circumferential panel; at the connection between the top cover 2 and the circumferential panel, and at the connection between the bottom shell 3 and the circumferential panel, both protrude from the circumferential panel; a handle 11 is fixed to the top of the top cover 2. In this embodiment, the number of handles 11 is two and they are symmetrically arranged.
[0039] As Figure 2 shown, on the upper side or the lower side of the circumferential panel, there are an interface 4 and a heat dissipation port 5;
[0040] The closed cover 1 circumferentially surrounds the circumferential panel and is slidably connected to the circumferential panel, sliding up and down along the circumferential panel. When the closed cover 1 is located on the side where the interface 4 and the heat dissipation port 5 are located, it can cover the interface 4 and the heat dissipation port 5. Through the protruding top cover 2 and bottom shell 3, the closed cover 1 is limited in the up and down direction.
[0041] Specifically, the circumferential panel includes a front panel 6, a rear panel, a left panel, and a right panel 7; on the upper side of the front panel 6, there is an interface 4 if any. In this embodiment, there is also a display window opened. On the upper sides of the left panel and the right panel 7, there are heat dissipation ports 5. In this embodiment, the heat dissipation ports 5, the interface 4, and the display window are arranged horizontally and are on the same horizontal plane.
[0042] The height of the closed cover 1 is 1 / 2 of the height of the front panel 6, and the closed cover 1 is made of an integrally formed plastic material;
[0043] On the left and right sides of the front panel 6, and on the left and right sides of the rear panel, guide grooves 8 are longitudinally provided, and the guide grooves 8 extend from the tops of the front panel 6 and the rear panel to the bottoms.
[0044] As Figure 3 shown, on the inner side of the closed cover 1, there is a guide bar 9 corresponding to the guide groove 8 longitudinally, and the guide bar 9 is embedded in the guide groove 8. In this embodiment, the guide bar 9 on the closed cover 1 is integrally formed.
[0045] On both sides of the upper part and both sides of the lower part of the guide groove 8, symmetrical notches are provided, which are circular notches in this embodiment; on both sides of the upper part of the guide bar 9, protrusions 10 are provided. When the closing cover 1 slides upward to the maximum height, the protrusions 10 can be embedded into the upper notches, and when the closing cover 1 slides downward to the lowest height, the protrusions 10 can be embedded into the lower notches.
[0046] In this solution, the closing cover 1 is designed to fit closely with the circumferential panel to cover all the interfaces 4 (such as USB-A, Type-C and other charging / output interfaces 4) and the heat dissipation openings 5. A guide bar 9 is provided on the circumferential panel and cooperates with the guide groove 8 to guide the up and down sliding of the closing cover 1.
[0047] Operation method: When the power bank is in a non-use state, slide the closing cover 1 to the highest position to completely cover all the interfaces 4 and the heat dissipation openings 5, forming a sealed environment to effectively prevent external factors such as dust and water vapor from invading.
[0048] When the user needs to charge or supply power, slide the closing cover 1 downward along the guide bar 9 to the lowest position. During this process, the heat dissipation openings 5 are exposed, and at the same time the interfaces 4 are also exposed for the user to connect and use.
[0049] The design of the closing cover 1 cleverly combines the two functions of protection and heat dissipation, and realizes the state switching by the way of up and down sliding. It effectively solves the contradiction between poor heat dissipation and pollution of the interfaces 4, automatically adapts to the heat dissipation requirements without additional operation by the user, ensures the safe and stable operation of the device, and improves the convenience, safety and use experience of the device operation.
