Description

Technical Field

[0001] This application belongs to the technical field of tire pressure monitoring equipment, and more specifically, relates to a signal receiving device. Background Technology

[0002] Heavy vehicles require particular attention to axle temperature and / or tire pressure during operation. Generally, due to the longer length of heavy vehicles, meaning longer wireless signal transmission links, signals from tire pressure sensors or axle temperature sensors are difficult to transmit clearly and without loss to the receiving module in the driver's cab. Therefore, signal relay reinforcement is necessary. However, because the driving trajectories of heavy vehicles are relatively random, and the temperature in the driving area varies considerably, low temperatures may affect the normal discharge of the battery in the signal receiving equipment, thus affecting the normal operation of related detection components. Utility Model Content

[0006] A heating element electrically connected to the control module is covered on the outer periphery of the battery. The heating element is used to heat the battery to raise its temperature.

[0017] To make the technical problems, technical solutions and beneficial effects to be solved by this application clearer, the following describes this application in further detail with reference to the accompanying drawings and embodiments.

[0018] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0020] When a component is said to be "connected to" another component, it can be directly connected to the other component or indirectly connected to that other component.

[0021] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0023] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0024] Please refer to the following: Figures 1 to 3 The signal receiving device provided in the embodiments of this application will now be described.

[0025] It is understood that the signal receiving device provided in this application embodiment is applicable to heavy vehicles, such as heavy trucks, semi-trailer trucks, and buses. Specifically, it is mounted on the vehicle chassis to receive data signals from tire pressure monitoring devices in each tire or axle temperature sensors on different axles, and transmits these data signals wirelessly to a receiving module located in the driver's cab, where a display module displays the specific values.

[0026] refer to Figures 1 to 3 It is understood that the signal receiving device provided in this application embodiment includes a housing 100, with a receiving cavity A inside the housing 100. A battery 200 and a main control board 300, electrically connected to each other, are disposed in the receiving cavity A. A control module 310, a signal relay module 320, and a temperature sensor are disposed on the main control board 300. The signal relay module 320 and the battery 200 are spaced apart. The temperature sensor is used to monitor the ambient temperature in the receiving cavity A. The signal relay module 320 is used to receive data signals from different tire pressure sensors or different axle temperature sensors and transmit these data signals to the receiving module in the cockpit, thereby achieving signal enhancement and ensuring lossless signal transmission.

[0027] Among them, an electric heating element electrically connected to the control module 310 is covered on the outer periphery of the battery 200. The electric heating element is powered by the battery 200 and is used to heat the battery 200 to raise the temperature of the battery 200 so that the battery 200 is in a suitable discharge power temperature range, thereby ensuring stable discharge power.

[0028] Specifically, the control module 310 incorporates a temperature control program that controls the start and stop of the heating element based on the temperature data obtained by the temperature sensor. For example, when the temperature data obtained by the temperature sensor is lower than the temperature threshold, the main control board 300 activates the heating element to heat the battery 200 until the ambient temperature of the battery 200 returns to above the threshold.

[0029] Specifically, refer to Figure 2 and Figure 3 The length of the battery 200 in the cavity A is less than the length and width of the main control board 300, and the battery 200 and the main control board 300 are stacked in the height direction. The signal relay module 320 is located in the area of ​​the main control board 300 that is not directly opposite the battery 200 in the height direction.

[0030] By covering the battery 200 with a heating element, when the signal receiving device is in a low-temperature environment, the control module 310 can control the heating element to heat the battery 200, thereby allowing the battery 200 to heat up to a suitable discharge temperature as soon as possible to maintain the discharge power and ensure that the module can work normally. In addition, by setting a distance between the signal relay module 320 and the battery 200, the electromagnetic interference from the battery 200 to the signal relay module 320 is reduced, which is beneficial to ensuring the stable reception and transmission of signals by the signal relay module 320.

[0031] refer to Figure 1 and Figure 2 In some embodiments, the housing 100 includes a first housing 110 and a second housing 120, the first housing 110 and the second housing 120 being detachably and fixedly connected; an interface is provided on the second housing 120, and pins pass through the interface to connect to the main control board 300.

[0032] Understandably, at least one interface is required. When only one interface is set, its pins are connected to the main control board 300 to charge the battery 200. When multiple interfaces are set, their pins are also connected to the main control board 300, but some interfaces are used to connect to other vehicle communication devices for signal reading and storage.

[0033] Further reference Figure 2An indicator light 330 is provided on the main control board 300. The second housing 120 is made of a transparent material, which can be plastic. The thickness of the area 124 on the second housing 120 corresponding to the indicator light 330 is less than the thickness of other areas. By setting the second housing 120 in this way, on the one hand, no additional light-transmitting component needs to be assembled on the second housing 120, thereby avoiding the situation where the sealing effect of the light-transmitting component deteriorates due to high-frequency vibration, moisture and other factors during vehicle operation, and causing dust or water to enter the receiving cavity A; on the other hand, the molding process of the second housing 120 is simple, and no secondary processing and assembly are required, which simplifies the assembly process and ensures the processing quality.

[0034] Generally, the pins are integrated with the second housing 120 via injection molding. However, due to limitations in the injection molding process and materials, a small gap still exists between the pins and the second housing 120. With prolonged use, moisture may seep into the receiving cavity A through this small gap, affecting the normal operation of the main control board 300 and the battery 200. Based on this, refer to... Figure 2 The second housing 120 has a groove 122 on the side facing the receiving cavity A. The groove 122 corresponds to the interface, and each pin is located in the groove 122. The groove 122 is used for filling with sealant. By filling the groove 122 with sealant, the sealant can completely fill the gap, thereby reducing the number and diameter of the gaps and achieving a sealing effect.

[0035] Understandably, during assembly, after the main control board 300 is soldered to the pins, the battery 200 is connected to the main control board 300. During this process, the main control board 300 is connected to the second housing 120 as a whole. Then, the main control board 300 is inserted into the first housing 110, while the second housing 120 is fixedly connected to the first housing 110.

[0036] refer to Figures 1 to 3 Furthermore, the second housing 120 is fastened to the first housing 110 by screws. A sealing groove 111 is provided on the surface of the first housing 110 that abuts against the second housing 120, and a sealing ring 112 is fitted into the sealing groove 111. A corresponding sealing protrusion 123 is provided on the second housing 120. When the second housing 120 and the first housing 110 are fastened together, the sealing protrusion 123 is fitted into the sealing groove 111 and abuts against the sealing ring 112. Thus, the sealing effect between the first housing 110 and the second housing 120 is good.

[0037] Further reference Figure 3The first housing 110 has slots 113 on its two opposing inner sidewalls, and the main control board 300 is mounted between the two opposing slots 113; the battery 200 is disposed on one side of the slots 113. In this way, after the main control board 300 is soldered to the pins, the main control board 300 can be prevented from shaking and breaking at the connection with the pins during the process of inserting the main control board 300 into the first housing 110.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
