Description

Technical Field

[0001] This application relates to the field of circuit devices for power supply or distribution, and more particularly to an emergency power supply. Background Technology

[0002] An emergency power supply is a portable jump starter that integrates power supply and charging functions. For example, it can help start a car when the battery is dead, the engine has stalled, or the vehicle is broken down. In addition to providing power, emergency power supplies can also achieve more functions by incorporating additional features.

[0003] Some emergency power supplies on the market are equipped with gas supply components, enabling them to not only charge but also inflate. However, the gas supply pipes of these components are easily deformed or damaged by pressure and impact, rendering them unable to supply gas properly. Utility Model Content

[0004] This application provides an emergency power supply, comprising: a housing having a receiving space; a storage assembly disposed outside the housing, the storage assembly including a cover plate and a connector, the connector being disposed between the cover plate and the housing to form a storage space between the cover plate and the housing; and a gas supply assembly including a gas supply body and a gas supply pipe communicating with the gas supply body, the gas supply body being disposed within the receiving space, and the gas supply pipe being at least partially located outside the housing and capable of being stored within the storage space.

[0005] In the technical solution of this application embodiment, because an air supply component is provided, the emergency power supply can not only supply power to vehicle batteries, but also inflate tires, expanding the applicability of the emergency power supply and helping to increase its importance and frequency of use. Since a storage component is provided on the outside of the housing, and the air supply pipe is stored within this component, the position of the air supply pipe relative to the housing is constrained, allowing it to be neatly stored on the housing surface, facilitating the storage and carrying of the emergency power supply. Because the air supply pipe is stored within the storage space between the cover and the housing, it is protected by the cover, preventing it from being squeezed, deformed, or even damaged, thus improving the reliability of the air supply component.

[0006] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

[0022] The following explanation is based on the accompanying drawings.

[0023] This application provides an emergency power supply, such as Figures 1 to 4As shown, it includes: a housing 10 having a receiving space; a storage assembly 20 disposed outside the housing 10, the storage assembly 20 including a cover plate 21 and a connector 22, the connector 22 being disposed between the cover plate 21 and the housing 10 so that a storage space is formed between the cover plate 21 and the housing 10; and an air supply assembly 30 including an air supply body 31 and an air supply pipe 32 communicating with the air supply body 31, the air supply body 31 being disposed within the receiving space, and the air supply pipe 32 being at least partially located outside the housing 10 and capable of being stored within the storage space.

[0024] The emergency power supply includes a housing 10, a storage assembly 20, and an air supply assembly 30. The air supply assembly 30 is partially housed inside the housing 10. The storage assembly 20 is located outside the housing 10 and is capable of housing the portion of the air supply assembly 30 located outside the housing 10.

[0025] The housing 10 has a receiving space for accommodating part of the gas supply assembly 30, and can also accommodate the battery 40, circuit board assembly, etc. The side of the housing 10 facing the receiving space is considered the interior of the housing 10, and the side of the housing 10 away from the receiving space is considered the exterior of the housing 10.

[0026] The air supply assembly 30 includes an air supply body 31 and an air supply pipe 32. The air supply body 31 is located inside the housing 10 and is connected to the air supply pipe 32 for supplying air to the air supply pipe 32. One end of the air supply pipe 32 is connected to the air supply body 31, and the other end of the air supply pipe 32 is located outside the housing 10. The air supply pipe 32 may be entirely located outside the housing 10, with the air supply port of the air supply body 31 located outside the housing 10 and the air supply pipe 32 connected to the air supply port. Alternatively, the air supply pipe 32 may be partially located outside the housing 10 and partially located inside the housing 10, connected to the air supply body 31. A mating head may be provided at the end of the air supply pipe 32 located outside the housing 10 for engaging and connecting the vehicle tire.

[0027] For example, the air supply unit 31 is an air pump. The inner diameter of the air pump cylinder can be selected according to actual needs, and this embodiment does not specifically limit this.

[0028] The emergency power supply also includes a bracket, which is set in the receiving space and at least abuts against the gas supply body 31 to fix the position of the gas supply body 31 relative to the housing 10.

[0029] Furthermore, a flexible pad is installed at the contact point between the gas supply unit 31 and the support to reduce vibration.

[0030] The storage assembly 20 includes a cover plate 21 and a connector 22. The cover plate 21 and the housing 10 are spaced apart. One side of the connector 22 is connected to the cover plate 21, and the other side is connected to the housing 10, thereby fixing the relative position of the cover plate 21 and the housing 10. The gap between the cover plate 21 and the housing 10 forms a storage space, into which the air supply pipe 32 can enter and be protected.

[0031] In the technical solution of this application embodiment, since an air supply component 30 is provided, the emergency power supply can not only supply power to vehicle batteries, but also inflate tires, expanding the applicability of the emergency power supply and helping to increase its importance and frequency of use. Because a storage component 20 is provided outside the housing 10, and the air supply pipe 32 is housed within the storage component 20, the position of the air supply pipe 32 relative to the housing 10 is constrained, allowing the air supply pipe 32 to be neatly housed on the surface of the housing 10, facilitating the storage and carrying of the emergency power supply. Since the air supply pipe 32 is housed within the storage space between the cover plate 21 and the housing 10, the air supply pipe 32 is protected by the cover plate 21, preventing it from being squeezed, deformed, or even damaged, thus improving the reliability of the air supply component 30.

[0032] In some embodiments, the number of connectors 22 is one, and one end of the connector 22 is connected to the cover plate 21 and is located in the central region of the cover plate 21.

[0033] A connector 22 is provided on the side of the cover plate 21 facing the housing 10. One end of the connector 22 is connected to the cover plate 21, and the other end of the connector 22 is connected to the housing 10. The connection point between the connector 22 and the cover plate 21 is located in the central area of ​​the cover plate 21. The storage space around the connector 22 can be used to store the air supply pipe 32.

[0034] In practical applications, the connector 22 may or may not have a channel 22a.

[0035] When the connector 22 has a channel 22a that passes through it, the air supply pipe 32 can be inserted through the channel 22a. In use, the air supply pipe 32 can be inserted through the channel 22a to limit its position. If the air supply pipe 32 is long, it can be directly wrapped around the periphery of the connector 22 and stored in the storage space, or part of the air supply pipe 32 can be inserted through the channel 22a and part of it can be wrapped around the periphery of the connector 22 and stored in the storage space.

[0036] When the connector 22 does not have a channel 22a, the air supply pipe 32 can be completely wrapped around the periphery of the connector 22 and stored in the storage space.

[0037] The air supply pipe 32 can be wrapped around the connector 22 located in the central area, so that most of it is located in the storage space after wrapping, thus protecting the air supply pipe 32 as much as possible.

[0038] In some embodiments, such as Figure 3 and Figure 4 As shown, there are multiple connectors 22, which are spaced apart along the extension direction of the cover plate 21.

[0039] Multiple connectors 22 may be evenly or unevenly arranged along the extension direction of the cover plate 21. The air supply pipe 32 may be serpentine or coiled and wound between the connectors 22 and limited by the connectors 22.

[0040] To enhance the stability of the connection 22 in constraining the air supply pipe 32, the connection 22 divides the storage space into a channel 22a, through which the air supply pipe 32 can pass and be limited by the wall of the channel 22a.

[0041] Optionally, the connector 22 is constructed with a channel 22a extending through itself.

[0042] Alternatively, two connectors can form a connector group, with the two connectors 22 in each connector group, together with the cover plate 21 and the housing 10, forming a channel 22a. When multiple connectors 22 are evenly arranged along the extension direction of the cover plate 21, a channel 22a can be formed between two adjacent connectors 22. Of course, along the extension direction of the cover plate 21, the connector groups can also be randomly arranged, so that the spacing between the connectors 22 is uneven.

[0043] In one specific embodiment, the connector 22 is a connecting plate located between the cover plate 21 and the housing 10. One side of the connecting plate is connected to the cover plate 21, and the other side is connected to the housing 10. The two connecting plates are spaced apart from each other, and the two connecting plates, the cover plate 21, and the housing 10 together form a channel 22a. Every two connecting plates constitute a connecting plate group, and at least two connecting plate groups are provided.

[0044] The shape of channel 22a is not specifically limited. The cross-sectional shape of channel 22a can be circular, polygonal, elliptical, irregular, etc., where irregular refers to other symmetrical or asymmetrical shapes other than those listed above.

[0045] In use, the user can thread the air supply pipe 32 through any one or more channels 22a, so that the air supply pipe 32 is coiled or snake-shaped and stored. The length of the air supply pipe 32 can be selected and set according to actual needs, and there is no specific limitation on it.

[0046] Therefore, the connector 22 restricts multiple positions of the air supply pipe 32, which helps to keep the air supply pipe 32 neat and securely stored.

[0047] In some embodiments, the cover plate 21 extends along the length of the emergency power supply.

[0048] The extension direction of the cover plate 21 may be parallel to the length direction of the emergency power supply. The cover plate 21 may be disposed on one side of the housing 10 along the thickness direction of the emergency power supply, and the connectors 22 may be spaced apart along the length direction of the emergency power supply.

[0049] Optionally, channel 22a extends along the height direction of the emergency power supply.

[0050] The length, thickness, and height of the emergency power supply are perpendicular to each other.

[0051] Therefore, the cover plate 21 can be set to be longer, so that the storage space is larger and the protection range of the air supply pipe 32 can be increased.

[0052] In some embodiments, the connector 22 may be a component that is independent of the cover plate 21 and the housing 10.

[0053] In some embodiments, the cover plate 21, the connector 22 and the housing 10 are integrally formed.

[0054] Therefore, the cover plate 21, the connector 22 and the housing 10 are firmly connected, and the production is quick.

[0055] In some embodiments, such as Figures 1 to 4 As shown, the housing 10 has a first vent 10a and a second vent 10b that communicate with the receiving space, and the first vent 10a and the second vent 10b are arranged at intervals.

[0056] Both the first vent 10a and the second vent 10b are connected to the receiving space of the housing 10, allowing external air to enter the receiving space through the first vent 10a and the second vent 10b. The first vent 10a and the second vent 10b can be respectively opened on different surfaces of the housing 10, or they can be opened separately on the same side surface of the housing 10. To ensure unobstructed airflow, the first vent 10a and the second vent 10b can be opened on the surface of the housing 10 where no receiving component is provided.

[0057] In one specific embodiment, the housing 10 has a first surface and a second surface, which are located on opposite sides of the housing 10 along the length of the emergency power supply, and the extending directions of the first and second surfaces intersect. A first vent 10a is disposed on the first surface, and a second vent 10b is disposed on the second surface. Thus, the airflow directions entering from the first vent 10a and the second vent 10b intersect, which helps to extend the airflow path within the containment space and improve the heat dissipation effect within the containment space.

[0058] Furthermore, in order to improve the heat dissipation effect within the housing space, a fan can be installed inside the housing space.

[0059] The shapes of the first vent 10a and the second vent 10b are not specifically limited and can be circular, polygonal, elliptical, irregular, etc. Among them, irregular shape refers to other symmetrical or asymmetrical shapes other than those listed above.

[0060] Therefore, the air supply unit can obtain air through the first vent 10a and the second vent 10b without the need for additional air intake components, resulting in a simple structure that saves space. Furthermore, the fact that air enters and exits from the mutually separated first vent 10a and second vent 10b helps to increase the amount of airflow entering and allows the airflow to pass through more areas of the containment space, thereby aiding in the heat dissipation of the containment space.

[0061] In some embodiments, continue reading Figures 1 to 4 The emergency power supply also includes a carrying handle 70 located on the housing 10.

[0062] The handle 70 can be securely attached to the housing 10 using fasteners. The periphery of the handle 70 can be covered with a soft rubber layer for a better grip.

[0063] This makes it easy for users to move and carry emergency power supplies.

[0064] In some embodiments, continue reading Figures 1 to 4 The handle 70 is provided with an anti-slip part 71.

[0065] The handle 70 can be constructed with raised and recessed anti-slip textures to form an anti-slip part 71. The specific shape of the anti-slip textures is not particularly limited; for example, the shape of the anti-slip textures can be wavy, dotted, straight, etc.

[0066] The specific material of the anti-slip part 71 is not limited. For example, it can be silicone or other materials that can increase friction. This embodiment does not make specific limitations on this.

[0067] Therefore, when the user holds the handheld part 70, the emergency power supply is less likely to slip from the user's hand, making the emergency power supply easier to move and carry.

[0068] In some embodiments, such as Figure 4 As shown, the emergency power supply also includes a battery 40 and a heating element. The battery 40 is used to power the gas supply assembly, and the heating element is used to heat the battery 40.

[0069] Both the battery 40 and the heating element are housed within the receiving space and are electrically connected to each other. The heating element can be positioned in contact with or near the battery 40. Furthermore, the battery 40 and / or the heating element can abut against a bracket used to secure the position of the battery 40 and / or the heating element.

[0070] For example, the heating element uses a positive temperature coefficient (PTC) material to achieve automatic temperature limiting.

[0071] Therefore, the heating element can raise the ambient temperature near the battery 40 at low temperatures, ensuring the normal operation of the battery 40.

[0072] Furthermore, the heating element has a charging interface 80 or a wire, which can be electrically connected to an external power source through the charging interface 80 or the wire, thereby raising the ambient temperature to a temperature at which the battery 40 can operate when the ambient temperature is too low and the battery 40 cannot supply power normally.

[0073] In some embodiments, such as Figures 2 to 4 As shown, the emergency power supply also includes a battery 40 and a lighting component 50. The battery 40 is connected to the lighting component 50 and is used to power the lighting component 50.

[0074] The lighting component 50 is at least partially housed within the receiving space, and a through-hole is formed in the housing 10 so that the light-emitting position of the lighting component 50 provides a light source outward through the through-hole. The battery 40 is housed within the receiving space, and the lighting component 50 is electrically connected to the battery 40.

[0075] Thus, a flashlight can provide illumination.

[0076] In some embodiments, the emergency power supply also includes a circuit board assembly housed in a receiving space and electrically connected to the battery 40.

[0077] The lighting component 50 and / or heating element can be electrically connected to the battery 40 via a circuit board.

[0078] For example, the circuit board assembly is a printed circuit board (PCBA) manufactured entirely using surface mount technology (SMT) or dual in-line package (DIP).

[0079] In some embodiments, such as Figure 3 and Figure 4 As shown, the emergency power supply also includes a charging interface 80.

[0080] The charging interface 80 is partially housed within the receiving space, with the other part exposed to the outside of the housing 10. The charging interface 80 is electrically connected to the battery 40 via a circuit board assembly and is used for electrical connection to external devices. The charging interface 80 can also be used to connect to an external power source to charge the battery 40.

[0081] Multiple charging ports 80 can be provided, and each charging port 80 can use different or the same type of connector. The charging port 80 must use at least an EC8 connector. The charging port 80 can also use USB connectors such as Type-A, Type-B, Type-C, Micro-A, and Mini-B.

[0082] Furthermore, a protective cover is provided at the charging port 80, and the protective cover is detachably connected to the housing 10.

[0083] Optionally, the emergency power supply also includes a cable. One end of the cable is electrically connected to the battery 40, and the other end has an EC8 connector for electrically connecting to external devices, such as the charging port of a vehicle battery.

[0084] In some embodiments, such as Figure 2 and Figure 4 As shown, the emergency power supply also includes a display screen 60, which is disposed in the housing 10 to at least display the operating status of the emergency power supply.

[0085] The emergency power supply also includes a display screen 60, which is embedded in the surface of the housing 10 and used to display the operating status of the emergency power supply. The display screen 60 can be electrically connected to the battery 40 to display the battery's charge level. The display screen 60 can also be electrically connected to a circuit board to display information such as the battery's charge level, the air pressure of the gas supply component 30, and the temperature of the heating element.

[0086] A button is provided on the side surface of the housing 10 where the display screen 60 is located. The button is used to start and stop the battery 40. Multiple buttons may be provided, and each button can control the start and stop of the heating element and the lighting component respectively.

[0087] In some embodiments, the emergency power supply also includes a flexible pad. The flexible pad is disposed on the side of the housing 10 away from the handle 70.

[0088] The housing 10 contacts the external support surface through a flexible pad. The flexible pad can absorb external impacts and collisions, and also prevent slipping.

[0089] In some embodiments, the display screen 60 and the storage component 20 are respectively disposed on opposite sides of the housing 10 along the length direction of the emergency power supply.

[0090] The display screen 60 and the storage assembly 20 are respectively disposed on both sides of the housing 10 along the thickness direction of the emergency power supply. The carrying handle 70 and the flexible pad can be respectively disposed on both sides of the housing 10 in a direction perpendicular to the thickness direction of the emergency power supply.

[0091] Therefore, the storage component 20 does not obstruct the display screen 60, avoiding mutual interference between the two.

[0092] The above embodiments are merely illustrative of the technical solutions of this application and are not intended to limit it.
