Description
Technical Field
[0001] This utility model relates to the field of mountain bikes, and in particular to a structure that integrates a mountain bike frame and a battery compartment. Background Technology
[0002] The integrated structure of the mountain bike frame and battery compartment is an important innovative design in the field of electric mountain bikes. By integrating the battery into the frame, a balance is achieved between performance optimization and a simple appearance. The battery compartment is usually located in the downtube or center tube area of the frame, forming an integrated structure with the main frame. This design improves frame rigidity and optimizes the riding experience, such as significantly improving downhill stability and pedal clearance. As part of the frame structure, the battery compartment can also enhance torsional resistance.
[0003] Deep integration of the battery compartment may lead to complex maintenance, requiring the motor to be disassembled to remove the battery, and replacing the battery cells requires specialized tools, making the operation process very cumbersome. The enclosed structure can still easily cause the battery to overheat in extreme environments (such as long-term vehicle operation). To address this, we propose an integrated structure for the mountain bike frame and battery compartment. Utility Model Content
[0004] The main purpose of this utility model is to provide an integrated structure for the mountain bike frame and battery compartment, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The lower surface of the frame has an air inlet duct on one side of the exhaust duct, and the moisture-absorbing sponge is embedded in the upper part of the air inlet duct.

[0008] Furthermore, the battery compartment body includes a fixing frame, a pressure plate, a compartment body, and fixing bolts. The fixing frame is fitted onto the surface of the compartment body below. There are two sets of pressure plates and four sets of fixing bolts.
[0009] Furthermore, the chamber is embedded in the cavity at one side, and one side of the pressure plate is hinged to the inner surface of the cavity. The pressure plate, the fixing frame, and the frame are connected by fixing bolts.
[0010] Furthermore, the heat dissipation structure includes a mounting plate, a heat absorption plate, a mounting frame, a cooling fan, and a support frame. The mounting plate is fixedly mounted on the upper surface of the heat absorption plate, and the mounting frame is embedded in one side surface of the mounting plate.

[0011] Furthermore, the heat absorption plate is embedded inside the cavity between the exhaust duct and the inlet duct, and the temperature sensor is embedded on one side of the mounting plate below the mounting frame.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0024] Reference Figure 1-6 A mountain bike frame and battery compartment integrated structure includes a frame body 1, a battery compartment body 2 is embedded in one side of the frame body 1, a heat dissipation structure 3 is embedded in the other side of the frame body 1, and a temperature sensor 4 is embedded in one side surface of the heat dissipation structure 3.
[0025] Specifically, the battery compartment body 2 is fixed inside the frame body 1, so that it can be directly removed when replacing the battery. The heat dissipation structure 3 is located inside the frame body 1 and on one side of the battery compartment body 2 to dissipate heat inside the frame body 1. The temperature sensor 4 monitors the air temperature inside the frame body 1.
[0026] In a preferred embodiment, the frame body 1 includes a pedal 101, a cavity 102, a frame 103, an exhaust duct 104, an air inlet duct 105, a moisture-absorbing sponge 106, and a filter screen 107. The upper surface of the frame 103 has an cavity 102, and the pedal 101 is embedded in the upper part of the cavity 102. The lower surface of the frame 103 has an exhaust duct 104 on one side, and there are multiple exhaust ducts 104. The lower surface of the frame 103 has an air inlet duct 105 on one side of the exhaust duct 104, and the moisture-absorbing sponge 106 is embedded in the upper part of the air inlet duct 105. The filter screen 107 is embedded in the lower part of the air inlet duct 105.
[0027] Specifically, the interior of the frame 103 is sealed by the pedal 101. Air enters the cavity 102 through the air inlet 105 and is filtered by the filter screen 107 before entering the cavity 102. The air is then absorbed by the moisture-absorbing sponge 106 and discharged through the exhaust duct 104. The frame 103 is the frame of the mountain bike, which is covered by the pedal 101. Multiple exhaust ducts 104 are used for air discharge. Outside air enters the cavity 102 through the air inlet 105. Dust and impurities in the air are filtered by the filter screen 107. The dust on the filter screen 107 can be cleaned by an external cleaning brush. The moisture-absorbing sponge 106 is a functional sponge with high water absorption and water retention properties. It quickly absorbs and stores water or liquid through its internal porous structure, thereby reducing the air humidity inside the cavity 102. When the battery inside the battery compartment 2 generates heat during operation, it can dry the moisture-absorbing sponge 106. The interior of the frame 103 has four sets of screw holes on the lower surface.
[0028] In a preferred embodiment, the battery compartment body 2 includes a fixing frame 201, a pressure plate 202, a compartment body 203, and fixing bolts 204. The fixing frame 201 is fitted onto the surface of the compartment body 203 below. There are two sets of pressure plates 202 and four sets of fixing bolts 204.
[0029] Specifically, the battery is loaded into the compartment 203, which is fixed by the fixing frame 201 and the pressure plate 202. The compartment 203 is provided with a wire groove to facilitate the connection of wires. The fixing frame 201 is provided with holes at the four corners. The upper surface of the pressure plate 202 is provided with screw holes on both sides, and its interior is threaded.
[0030] In a preferred embodiment, the hopper 203 is embedded in the cavity 102 and located on one side. One side of the pressure plate 202 is hinged to the inner surface of the cavity 102. The pressure plate 202, the fixing frame 201 and the frame 103 are connected by fixing bolts 204.
[0031] Specifically, the compartment 203 is fixed inside the cavity 102 at one side, and the fixing bolts 204 are passed through the screw holes on the pressure plate 202, the holes on the fixing frame 201, and the screw holes on the frame 103 in sequence and tightened. Since the space for installing the fixing bolts 204 is small, it is inconvenient to disassemble and requires the use of specific tools. However, it is more convenient than disassembling the battery compartment body 2. The pressure plate 202 is hinged inside the cavity 102, thereby preventing the pressure plate 202 from separating from the frame 103.
[0032] In a preferred embodiment, the heat dissipation structure 3 includes a mounting plate 301, a heat absorption plate 302, a mounting frame 303, a cooling fan 304, and a support frame 305. The mounting plate 301 is fixedly mounted on the upper surface of the heat absorption plate 302. The mounting frame 303 is embedded in one side surface of the mounting plate 301. The support frame 305 is embedded in one side of the interior of the mounting frame 303. The cooling fan 304 is fixedly mounted on one side surface of the support frame 305.
[0033] Specifically, heat is absorbed by the heat absorption plate 302. When the cooling fan 304 is turned on, the air on one side is drawn into the interior of the mounting frame 303 by the cooling fan 304, thereby delivering the air. The cooling fan 304 is supported and fixed by the support frame 305. The model of the cooling fan 304 is CT140EX. The mounting frame 303 is located on the mounting plate 301 in the middle position. The high temperature air enters the interior of the mounting frame 303 from the side close to the support frame 305 and is discharged to the side away from the support frame 305.
[0034] In a preferred embodiment, the heat absorption plate 302 is embedded in the cavity 102 between the exhaust duct 104 and the inlet duct 105, and the temperature sensor 4 is embedded on one side of the mounting plate 301 below the mounting frame 303.
[0035] Specifically, by embedding the heat absorption plate 302 inside the cavity 102, the heat absorption plate 302 absorbs the surrounding heat, and the cooling fan 304 dissipates the heat. When the cooling fan 304 is started, it can draw in outside air through the air inlet slot 105, take away the heat on the heat absorption plate 302, and then discharge it through the air outlet slot 104. The temperature sensor 4 is model IRTP-500A, which can monitor the ambient temperature and transmit the signal to the control center, which then controls the cooling fan 304 to start.
[0036] It should be noted that during use, the heat inside the cavity 102 is absorbed by the heat absorption plate 302, and the cooling fan 304 draws in outside air through the air inlet slot 105. During the air circulation process, the heat on the heat absorption plate 302 is carried away and discharged through the exhaust slot 104. When it is necessary to replace the battery, simply open the pedal 101 to operate. When it is necessary to disassemble the battery compartment body 2, the fixing bolts 204 can be loosened with tools to remove the fixing frame 201.
[0037] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
