Detailed Implementation

[0041] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0042] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "inner", "outer" and other terms used in this utility model to indicate the orientation or positional relationship are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device and components referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0043] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0044] like Figure 1 and Figure 2As shown, this utility model embodiment provides a shell structure, including a first shell 10, the first shell 10 including a first shell surface 11 and a second shell surface 12, the first shell surface 11 and the second shell surface 12 being adjacent to each other; the first shell 10 also includes a fixing member 13 and a first connecting post 14, the fixing member 13 being disposed on the first shell surface 11 or the second shell surface 12, the fixing member 13 being used to connect the first connecting post 14, so that the first connecting post 14 is fixed to the first shell 10 by the fixing member 13; the side of the fixing member 13 facing away from the first shell surface 11 has a first preset distance L1 from the first shell surface 11, and the first connecting post 14 is disposed on the side of the fixing member 13 facing away from the first shell surface 11.

[0045] Based on the above technical solution, a fixing member 13 is provided on the first shell surface 11 or the second shell surface 12. The first shell surface 11 is used as a reference surface, the side of the fixing member 13 facing the first shell surface 11 is the bottom surface, and the side of the fixing member 13 facing away from the first shell surface 11 is the top surface. The top surface of the fixing member 13 and the first shell surface 11 have a first preset distance L1. In this embodiment, the first connecting post 14 is provided on the top surface of the fixing member 13, so that the distance between the bottom surface of the first connecting post 14 and the first shell surface 11 is the first preset distance L1. While keeping the height of the first connecting post 14 (i.e., the distance from the top surface of the first connecting post 14 to the first shell surface 11) constant, the length of the first connecting post 14 is reduced. During injection molding, the filling dimension of the first connecting post 14 in the mold is relatively short, and the temperature and pressure distribution during injection is more uniform, allowing the first connecting post 14 to solidify quickly and stably, thereby reducing the deviation of the inner hole of the first connecting post 14.

[0046] The first connecting post 14 can be used to connect with other shell surfaces of the shell structure. For example, the first connecting post 14 can connect to the connecting parts provided on another shell surface of the shell structure to fix the shell structure. The first connecting post 14 can also be used to connect components loaded on the shell structure, such as PCB boards, batteries, fans, etc., to fix the components to the shell structure.

[0047] In some embodiments, such as Figure 1 The first connecting post 14 may have an inner hole that extends axially along the first connecting post to allow other connecting parts to be inserted for connection, such as connecting posts, screws, bolts, etc. The inner hole can be threaded, interference-fitted, or snap-fitted with other connecting parts, and the inner hole can penetrate the axis of the first connecting post 14 to reach the fixing part.

[0048] In some embodiments, such as Figure 1 As shown, the second shell surface 12 surrounds the first shell surface 11 to form a receiving cavity.

[0049] Specifically, the first shell surface 11 is the bottom surface of the first shell 10, and the second shell surface 12 is the side surface of the first shell 10. The first shell surface 11 and the second shell surface 12 are integrally formed by injection molding or by 3D printing. In this embodiment, the second shell surface 12 surrounds the outer periphery of the first shell surface 11 to form a closed or semi-closed receiving cavity for placing electronic components such as circuit boards, motors, and batteries.

[0050] In some embodiments, such as Figure 1 As shown, the fixing member 13 is disposed in the receiving cavity, and the side of the fixing member 13 facing the first shell surface 11 has a second preset distance L2 from the first shell surface 11.

[0051] Specifically, the fixing member 13 has a gap with the first shell surface 11 within the receiving cavity, and the bottom surface of the fixing member 13 has a second preset distance L2 with the first shell surface 11. Therefore, the length of the fixing member 13 is the difference between the first preset distance L1 and the second preset distance L2. Compared to injection molding the first connecting post 14 onto the first shell surface 11, this embodiment provides the fixing member 13 within the receiving cavity and places the first connecting post 14 on the top surface of the fixing member 13, reducing the length of the first connecting post 14 (i.e., the first preset distance L1) to make the first connecting post 14 easier to solidify and form.

[0052] In some embodiments, such as Figure 1 As shown, the fastener 13 is located at the end of the second shell surface 12 away from the first shell surface 11, and the side of the fastener 13 facing the first shell surface 11 has a third preset distance L3 from the first shell surface 11.

[0053] Specifically, the fastener 13 is connected to the top edge (inner wall or outer wall) of the second shell surface 12. The fastener 13 and the top of the second shell surface 12 are integrally formed, or the fastener 13 is the top structure of the second shell surface 12. In this embodiment, the top of the second shell surface 12 and the first shell surface 11 have a third preset distance L3. The length of the first connecting post 14 is reduced while keeping the height of the first connecting post 14 unchanged, so that the first connecting post 14 is easier to solidify and form.

[0054] In some embodiments, such as Figure 2 As shown, the fastener 13 is connected to the second shell surface 12 within the receiving cavity, and the side of the fastener 13 facing the first shell surface 11 has a fourth preset distance L4 from the first shell surface 11.

[0055] Specifically, the fastener 13 is connected to the inner wall of the second shell surface 12, and the fastener 13 and the second shell surface 12 can be integrally formed. The bottom surface of the fastener 13 has a fourth preset distance L4 from the first shell surface 11. The first connecting post 14 and the fastener 13 are spaced apart from the first shell surface 11. The length of the first connecting post 14 is reduced while keeping the height of the first connecting post 14 unchanged, so that the first connecting post 14 is easier to solidify and form.

[0056] In some embodiments, such as Figure 2 As shown, the fastener 13 is connected to the second shell surface 12 within the receiving cavity, and the fastener 13 extends from the first shell surface 11 to the first connecting post 14.

[0057] Specifically, the fastener 13 is connected to the inner wall of the second shell surface 12, and the fastener 13 and the second shell surface 12 can be integrally formed. The bottom surface of the fastener 13 is connected to the first shell surface 11, and the top surface of the fastener 13 extends to the first connecting post 14 until it connects with the bottom surface of the first connecting post 14. The length of the first connecting post 14 is reduced while keeping the height of the first connecting post 14 unchanged, so that the first connecting post 14 is easier to solidify and form.

[0058] In some embodiments, such as Figure 1 and Figure 3 As shown, the outer wall of the first connecting column 14 is provided with a reinforcing member 15, which is used to strengthen the structural strength of the first connecting column 14.

[0059] Specifically, the reinforcing member 15 is disposed on the outer wall of the first connecting column 14, which improves the structural strength of the first connecting column 14 and prevents the first connecting column 14 from deforming or being damaged when subjected to external forces. In this embodiment, by improving the structural strength of the first connecting column 14 through the reinforcing member 15, the service life of the first connecting column 14 can be extended.

[0060] In some embodiments, such as Figure 1 As shown, the outer wall of the first connecting post 14 is provided with a plurality of reinforcing members 15, which are arranged at intervals around the center of the first connecting post 14.

[0061] Specifically, multiple reinforcing members 15 are disposed on the outer wall of the first connecting post 14. The multiple reinforcing members 15 are arranged at intervals around the center of the first connecting post 14 to improve the structural strength of the first connecting post 14. When the first housing 10 falls or is impacted, each reinforcing member 15 can disperse the impact force suffered by the first connecting post 14, thereby reducing the risk of the first connecting post 14 breaking.

[0062] In some embodiments, such as Figure 1As shown, the reinforcing member 15 extends upward from the bottom of the first connecting post 14. The height of the reinforcing member 15 is greater than or equal to one-half the height of the first connecting post 14, and the height of the reinforcing member 15 is less than or equal to two-thirds the height of the first connecting post 14.

[0063] Specifically, if the reinforcing member 15 extends too far upward from the bottom of the first connecting post 14, for example, if the reinforcing member 15 extends from the bottom to the top of the first connecting post 14, the reinforcing member 15 will affect the assembly of the first connecting post 14 with other housings. In this embodiment, based on the reinforcing member 15 being located on the outer wall of the first connecting post 14, a portion of space is reserved on the top outer wall of the first connecting post 14, so as not to affect the connection of the first connecting post 14 with other structures.

[0064] In one specific embodiment, the height of the reinforcing member 15 is equal to half the height of the first connecting post 14. The reinforcing member 15 extends upward from the bottom of the first connecting post 14 to the middle position of the first connecting post 14, and half the height of the top of the first connecting post 14 is reserved.

[0065] In some embodiments, the reinforcing members 15 are evenly distributed along the circumference of the first connecting post 14 and surround the center of the first connecting post 14. The first connecting post 14 has a uniform structural strength distribution in the circumferential direction and can withstand external force impacts from all parts of the circumferential direction.

[0066] In some embodiments, the reinforcing member 15 is disposed around a portion of the outer wall of the first connecting post 14 to locally reinforce the location of the first connecting post 14 that is susceptible to high stress or impact.

[0067] In some embodiments, the reinforcing member 15 and the first connecting post 14 are integrally formed.

[0068] Specifically, the reinforcing member 15 and the first connecting column 14 are integrally formed by injection molding, casting, forging or 3D printing to enhance the structural strength of the first connecting column 14.

[0069] In some embodiments, such as Figure 3 As shown, the housing structure also includes a second housing 20, which includes a third housing surface 21. The third housing surface 21 is connected to the first housing surface 11 or the second housing surface 12, so that the second housing 20 is connected to the first housing 10.

[0070] For example, the first shell surface 11 is the bottom surface of the first shell 10, the second shell surface 12 is the side surface of the first shell 10, the second shell surface 12 surrounds the outer periphery of the first shell surface 11 to form a receiving cavity, and the third shell surface 21 connects to the second shell surface 12 so that the second shell 20 covers the receiving cavity of the first shell 10 to protect the electronic components such as circuit boards, motors, and batteries inside the receiving cavity.

[0071] In some embodiments, such as Figure 3 As shown, the third shell surface 21 is provided with a second connecting post 22, which is used to connect the first connecting post 14 so that the second shell 20 is fixedly connected to the first shell surface 11.

[0072] Specifically, the first connecting post 14 is located on the side of the first housing 10 facing the second housing 20, and the second connecting post 22 is located on the side of the second housing 20 facing the first housing 10. When the second housing 20 covers the first housing 10, the second connecting post 22 corresponds to and connects with the first connecting post 14 to realize the assembly and fixation of the first housing 10 and the second housing 20, so that the housing structure has a sufficiently high structural strength to resist minor impacts and protect the internal electronic components.

[0073] In some embodiments, such as Figure 3 As shown, the second connecting post 22 is provided with a mounting hole 23 extending along the axial direction of the second connecting post 22, and the first connecting post 14 is partially inserted into the mounting hole 23 so that the second connecting post 22 connects to the first connecting post 14.

[0074] Specifically, after inserting the first connecting post 14 into the mounting hole 23, a fastening connector is inserted through the mounting hole 23 and the inner hole of the first connecting post 14. The mounting hole 23 and the inner hole of the first connecting post 14 can be threaded holes, and the fastening connector can be a screw. After the second connecting post 22 is connected to the first connecting post 14, a screw is inserted through the mounting hole 23 and the inner hole of the first connecting post 14 to ensure a tight fit between the second connecting post 22 and the first connecting post 14, thereby increasing the connection strength between them.

[0075] In some embodiments, the length of the first connecting post 14 is greater than 20 mm and less than 30 mm. The length of the first connecting post 14 is within this size range, allowing for rapid prototyping, reducing deviations in the inner hole, and meeting the assembly requirements of the first connecting post 14.

[0076] In one specific embodiment, the length of the first connecting post 14 is 25 mm.

[0077] In some embodiments, the side of the fastener 13 facing the first shell surface 11 has a hollow structure.

[0078] Specifically, if the bottom surface of the fastener 13 is filled with molded material between the bottom surface and the first shell surface 11, and the molded material is too thick, it can easily cause structural deformation of the fastener 13, such as displacement of the fastener 13. In this embodiment, a hollow structure is made between the bottom surface of the fastener 13 and the first shell surface 11, that is, no molded material is filled between the bottom surface of the fastener 13 and the first shell surface 11, so as to form a partially hollow structure, thereby preventing structural deformation of the fastener 13.

[0079] Secondly, this utility model provides a power supply device (not shown in the accompanying drawings), including a circuit board and a housing structure, with the circuit board disposed within the housing structure.

[0080] Specifically, the circuit board is equipped with various electronic components and connecting lines to realize the functions of the power supply equipment, including energy management, status monitoring, and protection control. In this embodiment, the circuit board is installed inside the housing structure to resist external impacts. The structural strength of the first connecting post 14 is enhanced by the reinforcing member 15, thereby enhancing the structural strength of the housing structure and protecting the internal circuit board.

[0081] For example, the power supply equipment is an emergency jump starter, a car battery, an outdoor energy storage device, a vehicle inverter, or a power tool product, etc. The power tool product includes at least one of an air pump, a blower, an electric wrench, and a dust blower.

[0082] In some embodiments, the power supply device further includes an energy storage module, which is connected within the housing structure and connected to a circuit board for storing electrical energy and supplying electrical energy to the power supply device.

[0083] For example, the energy storage module includes at least one of a rechargeable battery or a supercapacitor. The rechargeable battery has a high energy density, is capable of storing large amounts of electricity, and can withstand hundreds to thousands of charge-discharge cycles. The supercapacitor features high power density, rapid charge-discharge capability, and long cycle life.

[0084] The rechargeable batteries include at least one of sodium batteries, lithium batteries, and lead-acid batteries, and are suitable for applications requiring emergency or long-term power supply.

[0085] In some embodiments, the power supply device further includes an emergency start interface, which is located in the housing structure and is used to connect a cable to a car battery to provide power for starting the car.

[0086] Specifically, the emergency start interface is located on the outer surface of the housing structure to facilitate cable connection. The emergency start interface is connected to the energy storage module and the circuit board. When the connecting cable connects the emergency start interface to the car battery, the circuit board controls the energy storage module to provide power to the car battery.

[0087] In some embodiments, the power supply device further includes a cable for connecting to a car battery to provide power for starting the car.

[0088] Specifically, the cable is used to transfer electrical energy from the energy storage module in the power supply equipment to the car battery, thereby providing the power needed to start the car.

[0089] In some embodiments, the power supply device further includes a discharge interface disposed on the outer surface of the housing structure for connecting to the electrical equipment to supply power to the electrical equipment.

[0090] For example, the discharge interface includes at least one of an AC power socket, a DC power interface, a USB interface, a cigarette lighter interface, and a wireless charging pad.

[0091] In some embodiments, the power supply device further includes a charging interface disposed on the outer surface of the housing structure for connecting to an external power source to receive power from the external power source.

[0092] In some embodiments, the power supply device further includes a lighting device that can be used as emergency lighting to provide illumination. The lighting device includes at least one of the following: LED lamp, incandescent lamp, fluorescent lamp, magnesium lamp, xenon lamp, high-pressure pump lamp, and halogen lamp.

[0093] In some embodiments, the power supply device further includes a positive terminal and a negative terminal, which are connected to an energy storage module and are used to connect to internal vehicle devices to provide power for vehicle startup or power consumption.

[0094] Specifically, the positive and negative terminals can be directly connected to the energy storage module inside the housing structure, or indirectly connected to the energy storage module through a circuit board.
