Abstract
Description
Technical Field
[0001] This utility model relates to the field of power supply technology, and in particular to a portable power supply. Background Technology
[0002] With the continuous development of technology, electrical appliances are ubiquitous in our lives, such as vacuum cleaners, air pumps, and flashlights. Currently, some electrical appliances are detachably connected to a power bank to provide power. However, this solution has some drawbacks due to unreasonable structural design. For example, because the sliding engagement size between the power bank slot and the electrical appliance's contact part is fixed, the connection between the appliance and the power source is either loose or too tight, neither of which is conducive to use. Alternatively, adding a buckle / locking device can improve the connection stability, but it increases the number of independent parts and the manufacturing cost. Therefore, it is necessary to propose a new solution to address the above problems. Utility Model Content
[0003] In view of the above, the present invention addresses the deficiencies of the prior art and its main purpose is to provide a portable power source that solves the aforementioned problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A portable power bank includes a main body with a slot on its upper surface for connecting to a power receiving part of an electrical appliance. The slot has an inlet at the front end located on the side of the main body. An electrode contact and a data transmission contact are exposed in the slot. The cross-sectional area of the rear end of the slot is smaller than that of the front end, so that the power receiving part of the electrical appliance can be tightly engaged with the rear end of the slot after being inserted into place.
[0006] As a preferred embodiment, the rear end of the slot is closed to form a stop surface, so that the electrical contact part of the appliance contacts and positions itself against the stop surface after being inserted into place.
[0007] As a preferred embodiment, the upper surface of the body is also provided with a step for clearing the opening.
[0008] As a preferred embodiment, the cross-sectional area of the card slot gradually decreases from front to back.
[0009] As a preferred embodiment, the inner side of the slot is recessed with a locking recess that cooperates with the locking switch of the electrical appliance.
[0010] As a preferred embodiment, there are two electrode contacts, which protrude from the bottom surface of the slot and are arranged sequentially along the length of the slot.
[0011] As a preferred embodiment, there are two data transmission contacts, which protrude from the bottom surface of the slot and are located on both sides of the electrode contacts.
[0012] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:
[0013] By designing the cross-sectional area of the rear end of the slot to be smaller than that of the front end, the electrical contact part of the appliance can be tightly engaged with the rear end of the slot after it is inserted. This design allows the appliance to easily fit into the front part of the slot, while the appliance and the product can be securely connected at the rear end of the slot. Moreover, no other similar clips or clamps are needed. Its simple structure is easy to manufacture, low in cost, and its detachable design makes it applicable to various electrical appliances such as vacuum cleaners, air pumps, and flashlights. It has a wide range of applications and can be reused in different appliances, reducing battery production, saving resources, and benefiting environmental protection.
[0014] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0022] 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 merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0023] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0024] Please see Figures 1 to 5 This utility model provides a portable power bank, including a body 10. The upper surface of the body 10 has a slot 11 for connecting to the power receiving part 21 of an electrical appliance 20. The slot 11 has an inlet at its front end located on the side of the body 10. An electrode contact part 12 and a data transmission contact part 13 are exposed in the slot 11. The cross-sectional area of the rear end of the slot 11 is smaller than that of the front end, ensuring a tight connection between the power receiving part 21 of the electrical appliance 20 and the rear end of the slot 11 after insertion. This design allows the electrical appliance 20 to easily insert into the front of the slot 11, while the rear end of the slot 11 securely connects the electrical appliance 20 to the power bank. Furthermore, it eliminates the need for other similar clips or clamps, resulting in a simple structure, ease of manufacturing, low cost, and reusability for different electrical appliances. This reduces battery production, saves resources, and is beneficial to environmental protection.
[0025] Furthermore, the rear end of the slot 11 is closed to form a stop surface, so that the power receiving part 21 of the electrical appliance 20 contacts and is positioned with the stop surface after being inserted into place; in addition, it should be noted that in this embodiment, the slot 11 is a T-shaped slot.
[0026] Furthermore, an clearance step 14 is formed on the upper end surface of the body 10 to facilitate the alignment and engagement of the power receiving part 21 of the electrical appliance 20 with the slot 11.
[0027] Furthermore, the cross-sectional area of the slot 11 gradually decreases from front to back.
[0028] Furthermore, the inner side of the slot 11 is recessed with a locking recess 15 that cooperates with the locking switch 24 of the electrical appliance 20. When the power receiving part 21 of the electrical appliance 20 is inserted into the slot, the locking part 241 of the locking switch 24 will pop out and lock into the locking recess 15, thereby further strengthening the connection between the electrical appliance 20 and the product. When it is necessary to remove the power receiving part 21 of the electrical appliance 20 from the slot 11, press the locking switch 24 of the electrical appliance 20 by hand to make the locking part 241 first exit the locking recess 15, and then forcefully pull the power receiving part 21 out of the slot 11.
[0029] Furthermore, there are two electrode contact portions 12, which protrude from the bottom surface of the slot 11 and are arranged sequentially along the length of the slot 11. Correspondingly, the power receiving portion 21 of the electrical appliance 20 has a first sliding groove 22 that avoids the two electrode contact portions 12, so that the power receiving portion 21 of the electrical appliance 20 can be smoothly inserted into the slot 11.
[0030] Furthermore, there are two data transmission contacts 13, which protrude from the bottom surface of the slot 11 and are located on both sides of the electrode contact 12. Correspondingly, the power receiving part 21 of the electrical appliance 20 has a second sliding groove 23 that avoids the two data transmission contacts 13, so that the power receiving part 21 of the electrical appliance 20 can be smoothly inserted into the slot 11.
[0031] Additionally, the upper end of the body 10 is provided with a top cover 16 for covering the slot 11, and the top cover 16 has protrusions to increase friction.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
