Description

Technical Field

[0001] This application relates to the field of charging equipment, and more particularly to a temperature monitoring structure for a charging dock. Background Technology

[0002] With the increasing popularity of electronic devices, charging docks, as key devices that provide power to electronic devices, play an indispensable role in ensuring the normal use of electronic devices. As a result, the safety and reliability of charging devices are receiving more and more attention from users and the industry. The charging dock contains terminals, which are the core interfaces for the charging dock to transmit power. When an electronic device is charging, current flows to the device through the terminals. During this process, the terminals will generate heat due to the current passing through them.

[0003] Among related technologies, the existing technical solutions for terminal temperature monitoring in the industry are relatively uniform, and thermistors are generally used to monitor the terminal temperature. By controlling the terminal temperature in real time, the safe operation of charging equipment is guaranteed, and problems such as equipment damage caused by terminal overheating are reduced.

[0004] However, in practical applications, there is a gap between the thermistor and the terminal. This gap prevents the heat generated by the terminal from being transferred to the thermistor in a timely and efficient manner, resulting in a lag in temperature detection. This reduces the efficiency of the thermistor in responding to actual temperature changes at the terminal, making it difficult to achieve real-time and accurate monitoring of the terminal temperature and posing a potential hazard to the safe operation of charging equipment. Utility Model Content

[0005] To address the aforementioned issues, this application provides a temperature monitoring structure for a charging dock.

[0006] The temperature monitoring structure for a charging dock provided in this application adopts the following technical solution: it includes a terminal and a thermistor, and also includes a metal sheet, a terminal cover and a circuit board. The thermistor is fixed on the circuit board, the terminal is fixed on the terminal cover, a heat-conducting element is provided at the upper end of the thermistor, and the metal sheet is installed on the terminal, with the metal sheet abutting against the heat-conducting element.

[0007] By adopting the above technical solution, the thermistor is fixed on the circuit board, and the terminal is fixed on the terminal cover. First, the fixed assembly of the terminal and the terminal cover ensures the stability of the terminal position. Then, the metal plate is installed on the terminal. At the same time, a heat-conducting component is set on the upper end of the thermistor, and the metal plate abuts against the heat-conducting component, thus constructing a continuous heat transfer path and filling the physical gap between the thermistor and the terminal. This allows the heat generated by the current in the terminal to be quickly and efficiently transferred through the metal plate to the heat-conducting component, and then from the heat-conducting component to the thermistor. This eliminates the lag in temperature detection, greatly improves the efficiency of the thermistor in responding to the actual temperature changes of the terminal, realizes real-time and accurate monitoring of the terminal temperature, reduces the hidden dangers of charging equipment damage or safety accidents caused by the terminal overheating not being detected in time, and ensures the safe operation of the charging equipment.

[0008] Preferably, the metal sheet includes a connecting end and an abutting end, the connecting end and the abutting end are fixedly connected, the connecting end is fixedly connected to the terminal, and the abutting end abuts against the heat-conducting component.

[0009] By adopting the above technical solution, the connection end and the terminal are stably connected, and the contact end and the heat-conducting component are tightly contacted, thus constructing a continuous and stable heat transfer bridge between the terminal and the heat-conducting component, effectively filling the physical gap between the thermal sensor and the terminal.

[0010] Preferably, the terminal cover is provided with a first receiving groove, and the abutting end is built into the first receiving groove.

[0011] By adopting the above technical solution, the terminal cover is provided with a first receiving groove and the abutting end is built into it, which can provide the metal sheet with precise installation positioning and stable receiving space, effectively limiting the displacement or shaking of the metal sheet during the assembly of the charging base and long-term use, and reducing the change in the contact state between the connecting end and the terminal, and between the abutting end and the heat-conducting component caused by the displacement of the metal sheet position.

[0012] Preferably, the abutting end is provided with a first spring piece, the first receiving groove is provided with a clearance opening, and the first spring piece is inserted into the clearance opening.

[0013] By adopting the above technical solution, during the assembly process, when the first spring is inserted into the relief opening, it will be squeezed by the edge of the relief opening and undergo elastic deformation. This elastic deformation can adapt to the insertion space of the relief opening, ensuring that the first spring can be smoothly inserted into the receiving groove. After the first spring is fully inserted, the elastic deformation of the first spring will recover. The first spring after recovery will abut against the groove wall of the first receiving groove, thereby forming a reliable limiting and fixing of the metal sheet. This allows the metal sheet to remain stable in the first receiving groove, always maintaining the abutting end in contact with the heat-conducting component, reducing the interruption or loss of the heat transfer path due to the displacement of the metal sheet.

[0014] Preferably, the terminal cover is provided with a second receiving groove, the first receiving groove is connected to the second receiving groove, and the thermal sensor is disposed in the second receiving groove.

[0015] By adopting the above technical solution, the second receiving groove not only reserves a suitable receiving space for the heat-conducting component, but also the connection between the first receiving groove and the second receiving groove can guide the contact end in the first receiving groove to contact the heat-conducting component in the second receiving groove.

[0016] Preferably, the connecting end is provided with a second spring, which is fixedly connected to the terminal.

[0017] By adopting the above technical solution, the second spring piece at the connecting end is fixedly connected to the terminal. During the process of the first spring piece being inserted into the clearance opening of the first receiving groove, the second spring piece will simultaneously undergo elastic deformation toward the side wall of the terminal. This deformation can provide a certain displacement buffer space for the metal sheet as a whole, thereby smoothly completing the insertion and engagement of the first spring piece and the clearance opening. After the abutting end is fully inserted into the clearance opening, the second spring piece will immediately restore its elastic deformation. Together with the abutting limit of the first spring piece and the groove wall of the first receiving groove, a stable snap-fit ​​connection is formed between the metal sheet and the terminal cover. The first and second spring pieces ensure that the position of the metal sheet in the terminal cover is stable for a long time, thereby ensuring the abutting engagement between the abutting end and the heat-conducting component, providing reliable structural support for efficient heat transfer and accurate monitoring of terminal temperature by the thermal sensor.

[0018] Preferably, the circuit board is provided with a first snap-fit ​​component, and the terminal cover is provided with a first snap-fit ​​hole, wherein the first snap-fit ​​component and the first snap-fit ​​hole are snap-fitted together.

[0019] By adopting the above technical solution, the first snap-fit ​​component and the first snap-fit ​​hole form a snap-fit ​​engagement, realizing a stable connection between the circuit board and the terminal cover. At the same time, it effectively limits the relative displacement between the circuit board and the terminal cover during use. Since the thermal sensor is pre-fixed on the circuit board, the position of the circuit board will be synchronously positioned during the snap-fit ​​engagement of the first snap-fit ​​component and the first snap-fit ​​hole, thereby driving the thermal sensor to accurately enter the second receiving groove of the terminal cover. This ensures that the thermal sensor always maintains contact with the heat-conducting component in the second receiving groove, further improving the accuracy and reliability of terminal temperature monitoring.

[0020] Preferably, the terminal cover is provided with a mounting groove, the terminal is provided with a mounting part, the mounting part abuts against the groove wall of the mounting groove, and the first receiving groove communicates with the mounting groove.

[0021] By adopting the above technical solution, the wall of the mounting groove abuts against the mounting part, which radially and circumferentially limits the terminal and restricts the displacement of the terminal within the terminal cover. This provides a stable reference for the positioning of the metal sheet. At the same time, the connection between the first receiving groove and the mounting groove, because the connecting end is fixedly connected to the terminal, prevents the metal sheet from moving arbitrarily after the terminal is restricted. This ensures that the abutting end of the metal sheet can be accurately aligned with the clearance opening of the first receiving groove, and ultimately ensures that the abutting end can be smoothly inserted into the clearance opening. This lays the structural foundation for the subsequent stable transfer of heat from the terminal and the accurate temperature monitoring by the thermal sensor.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By fixing the terminals and terminal covers, the terminal position is first stabilized. Then, by installing the metal sheet and the terminal, and by contacting the metal sheet with the heat-conducting component, a continuous heat transfer path is constructed, filling the physical gap between the thermistor and the terminal. This allows the heat generated by the current in the terminal to be quickly and efficiently transferred from the metal sheet to the heat-conducting component, and then from the heat-conducting component to the thermistor. This eliminates the lag in temperature detection, significantly improves the efficiency of the thermistor in responding to actual temperature changes in the terminal, and enables real-time and accurate monitoring of the terminal temperature. This reduces the risk of damage to the charging equipment or safety accidents caused by undetected overheating of the terminal, ensuring the safe operation of the charging equipment.

[0035] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0036] This application discloses a temperature monitoring structure for a charging dock. (Refer to...) Figure 1 It includes a terminal 1, a thermal sensor 2, a metal sheet 3, a terminal cover 4, and a circuit board 5. There are two terminals 1 and two metal sheets 3, with one terminal 1 and two metal sheets 3 corresponding to each other. The thermal sensor 2 is fixed on the circuit board 5, and the terminal 1 is fixed on the terminal cover 4. A heat-conducting element 7 is provided on the upper end of the thermal sensor 2. The metal sheet 3 is installed on the terminal 1 and abuts against the heat-conducting element 7.

[0037] This demonstrates that the thermal sensor 2 is fixed on the circuit board 5, and the terminal 1 is fixed on the terminal cover 4. First, the fixed assembly of the terminal 1 and the terminal cover 4 ensures the stability of the terminal 1 position. Then, the metal sheet 3 is installed on the terminal 1. At the same time, a heat-conducting component 7 is set on the upper end of the thermal sensor 2, and the metal sheet 3 abuts against the heat-conducting component 7, thus constructing a continuous heat transfer path and filling the physical gap between the thermal sensor 2 and the terminal 1. This allows the heat generated by the current in the terminal 1 to be quickly and efficiently transferred through the metal sheet 3 to the heat-conducting component 7, and then from the heat-conducting component 7 to the thermal sensor 2. This eliminates the lag in temperature monitoring, significantly improves the efficiency of the thermal sensor 2 in responding to the actual temperature changes of the terminal 1, and achieves real-time and accurate monitoring of the temperature of the terminal 1. This reduces the potential for damage to the charging equipment or safety accidents caused by the terminal 1 overheating not being detected in time, and ensures the safe operation of the charging equipment.

[0038] Reference Figure 2 and Figure 3 Specifically, the metal sheet 3 includes a connecting end 31 and an abutting end 32. The connecting end 31 and the abutting end 32 are fixedly connected to form a structure similar to an L-shaped angle steel. The connecting end 31 is provided with a second spring sheet 311. The second spring sheet 311 has elastic deformation. There are two second spring sheets 311. One end of the second spring sheet 311 is fixedly connected to the connecting end 31, and the other end of the second spring sheet 311 is fixedly connected to the side wall of the terminal 1. The shape of the second spring sheet 311 is set as a flat sheet. The abutting end 32 is provided with a first spring sheet 321. The shape of the first spring sheet 321 is set as a flat sheet. The first spring sheet 321 also has elastic deformation, and there are two first spring sheets 321. One end of the first spring sheet 321 is fixedly connected to the abutting end 32.

[0039] Reference Figure 4 Furthermore, the terminal cover 4 is provided with a first receiving groove 41, as shown in the reference. Figure 5 and Figure 6 The first receiving groove 41 is provided with a relief groove 411, and the abutting end 32 is inserted into the relief groove 411. The relief groove 411 is provided with a relief opening 412. There are two relief openings 412, and the two relief openings 412 correspond one-to-one with the two first spring pieces 321. During the assembly process, the abutting end 32 slides into the relief groove 411 so that the first spring piece 321 is inserted into the relief opening 412. When the first spring piece 321 is inserted into the relief opening 412, it is squeezed by the edge of the relief opening 412 and generates elastic deformation. This elastic deformation can adapt to the insertion space of the relief opening 412, so that the first spring piece 321 can smoothly enter the first receiving groove 41. When the first spring piece 321 is fully inserted, the elastic deformation is restored and it abuts tightly against the groove wall to form a reliable limiting fixation, so that the metal piece 3 is stably embedded in the first receiving groove 41, and the stable cooperation between the abutting end 32 and the heat-conducting component 7 is continuously guaranteed.

[0040] Meanwhile, when the abutment end 32 slides into the relief groove 411, since the second spring piece 311 is fixedly connected to the terminal 1, during the insertion process of the first spring piece 321, the second spring piece 311 will simultaneously undergo elastic deformation toward the side wall of the terminal 1, providing displacement buffer space for the metal piece 3, ensuring that the abutment end 32 slides into the relief groove 411 smoothly. After the abutment end 32 is fully inserted, the elastic deformation of the second spring piece 311 recovers, and it abuts against the groove wall of the first spring piece 321 to form a double limit, realizing the stable engagement of the metal piece 3 and the terminal cover 4.

[0041] Furthermore, the first receiving groove 41 confines the abutting end 32 within it, providing a stable receiving space for the metal sheet 3, reducing displacement or shaking of the metal sheet 3 during assembly or use, ensuring that the abutting end 32 and the heat-conducting component 7 always maintain reliable contact, and maintaining the continuity of the heat transfer path. Through the synergistic effect of the first spring 321 and the second spring 311, the position of the metal sheet 3 within the cover is maintained stably for a long time, not only ensuring the continuous and reliable contact between the abutting end 32 and the heat-conducting component 7, but also ensuring efficient heat transfer and accurate monitoring of the terminal 1 temperature by the thermistor 2, providing solid structural support for the reliable operation of the charging base.

[0042] Reference Figure 7 Meanwhile, the terminal cover 4 is provided with a mounting groove 42, and the terminal 1 is provided with a mounting part 11. The mounting part 11 abuts against the groove wall of the mounting groove 42. The first receiving groove 41 is connected to the mounting groove 42. The groove wall of the mounting groove 42 abuts against the mounting part 11 to limit the terminal 1 radially and circumferentially, restricting the displacement of the terminal 1 in the terminal cover 4, providing a stable reference for the positioning of the metal sheet 3. At the same time, the connection between the first receiving groove 41 and the mounting groove 42, because the connecting end 31 is fixedly connected to the terminal 1, prevents the metal sheet 3 from moving arbitrarily after the terminal 1 is restricted. This ensures that the abutting end 32 of the metal sheet 3 can be accurately aligned with the clearance opening 412 of the first receiving groove 41, and ultimately ensures that the abutting end 32 can be smoothly inserted and fitted with the clearance opening 412, laying a structural foundation for the subsequent stable heat transfer of the terminal 1 by the metal sheet 3 and the accurate temperature monitoring by the thermistor 2.

[0043] Reference Figure 8 and Figure 9 Furthermore, the terminal cover 4 is provided with multiple snap-fit ​​protrusions 43, each snap-fit ​​protrusion 43 is provided with a first snap-fit ​​hole 431, and the circuit board 5 is provided with multiple first snap-fit ​​pieces 51. In this embodiment, the first snap-fit ​​pieces 51 also have elastic deformation. The first snap-fit ​​pieces 51 include four first snap-fit ​​rods 511 and connectors 512. The four first snap-fit ​​rods 511 and connectors 512 are fixedly connected. The connectors 512 are fixedly connected to the circuit board 5, and the connectors 512 are generally circular in structure. The four first snap-fit ​​rods 511 are provided at the upper end of the connectors 512.

[0044] Furthermore, when the first snap-fit ​​component 51 is snapped into the first snap-fit ​​hole 431, the four first snap-fit ​​rods 511, due to their elastic deformation characteristics, will automatically converge toward the center of the connector 512 to match the entrance size of the first snap-fit ​​hole 431 and smoothly extend into the first snap-fit ​​hole 431. After the first snap-fit ​​rod 511 is fully inserted into the cavity, the end of the first snap-fit ​​rod 511 away from the connector 512 will abut against the wall of the hole in the first snap-fit ​​hole 431, thereby achieving a stable snap-fit ​​between the first snap-fit ​​component 51 and the first snap-fit ​​hole 431. Furthermore, by having multiple such first snap-fit ​​components 51 and multiple first snap-fit ​​holes 431 snap-fit ​​one by one, the connection reliability between the circuit board 5 and the terminal cover 4 is further enhanced, ultimately achieving precise and firm fixation of the two.

[0045] Meanwhile, the terminal cover 4 is provided with a second receiving groove 44, and the thermal sensor 2 is pre-fixed on the circuit board 5. When the first snap-fit ​​member 51 on the circuit board 5 and the first snap-fit ​​hole 431 of the terminal cover 4 are snapped together, the thermal sensor 2, which is positioned synchronously with the circuit board 5, will fit and be built into the second receiving groove 44 of the terminal cover 4, so as to achieve precise assembly of the thermal sensor 2 in the preset space. The second receiving groove 44 is connected to the first receiving groove 41, and the abutting end 32 is exposed in the second receiving groove 44, which can guide the abutting end 32 in the first receiving groove 41 to abut with the heat-conducting member 7 in the second receiving groove 44.

[0046] Meanwhile, the second receiving groove 44 simultaneously reserves a suitable receiving space for the heat-conducting component 7. In this embodiment, the heat-conducting component 7 is set as thermal grease. The thermal grease is in a paste-like fluid form under normal conditions and has no fixed geometric shape. It can adapt to the gap space between the thermal sensor 2 and the metal sheet 3 as it is applied and squeezed. The common colors of thermal grease are white and gray. Although the contact surface between the thermal sensor 2 and the metal sheet 3 appears flat to the naked eye, there are tiny unevennesses at the micro level. When in direct contact, a large number of air layers will easily form. The thermal grease itself has a high thermal conductivity. After being applied, it forms a solid paste that can fully fill the micro gap between the two. The heat generated by the current in the terminal 1 is first transferred to the metal sheet 3, and then quickly and evenly conducted to the thermal sensor 2 through the thermal grease.

[0047] Reference Figure 10 and Figure 11In addition, this embodiment also includes a housing 6, which is provided with a plurality of positioning grooves 61, each of which corresponds to a plurality of snap-fit ​​protrusions 43. The positioning grooves 61 and the snap-fit ​​protrusions 43 are inserted and engaged. Furthermore, the terminal cover 4 is provided with a second snap-fit ​​member 45, which includes a plurality of second snap-fit ​​rods 451. In this embodiment, there are six second snap-fit ​​rods 451, which are fixedly connected to the terminal cover 4. The six second snap-fit ​​rods 451 also have elastic deformation. The housing 6 is provided with a second snap-fit ​​hole 62, and the six second snap-fit ​​rods 451 are snap-fitted and fixed to the second snap-fit ​​hole 62. At the same time, the housing 6 is provided with two mounting holes 63, each of which corresponds to two terminals 1, and the terminals 1 are built into the mounting holes 63.

[0048] The implementation principle of a temperature monitoring structure for a charging dock in this application embodiment is as follows: First, assemble terminal 1 and terminal cover 4. Align the mounting part 11 of terminal 1 with the mounting groove 42 of terminal cover 4, so that the mounting part 11 and the groove wall of the mounting groove 42 are tightly abutted. The groove wall of the mounting groove 42 forms radial and circumferential limits on terminal 1, reducing the displacement of terminal 1 and providing a stable reference for the subsequent positioning of metal sheet 3. Next, align the abutting end 32 with the first receiving groove 41 of terminal cover 4, so that the first spring piece 321 of the abutting end 32 mates with the relief opening 412 of the first receiving groove 41. During assembly, the first spring piece 321 is squeezed by the edge of the relief opening 412 and undergoes elastic deformation, smoothly sliding into the first receiving groove 41. After being fully inserted, the deformation is restored, and it abuts and limits with the groove wall of the first receiving groove 41. At the same time, the second spring piece 311 deforms towards the side wall of terminal 1 to provide displacement buffer. After assembly, the second spring piece 311 also restores its deformation, forming a double limit with the first spring piece 321, so that the metal sheet 3 is stably embedded in the first receiving groove 41, ensuring continuous contact with the heat-conducting component 7.

[0049] Next, the terminal cover 4 is fixed to the housing 6. First, the snap-fit ​​protrusion 43 of the terminal cover 4 is aligned with the positioning groove 61 of the housing 6 to initially position the terminal cover 4 in the housing 6. At this time, the second snap-fit ​​piece 45 and the second snap-fit ​​hole 62 are aligned. Then, the second snap-fit ​​piece 45 of the terminal cover 4 is aligned with the second snap-fit ​​hole 62 of the housing 6. When the terminal cover 4 is pushed, the snap-fit ​​protrusion 43 simultaneously engages with the positioning groove 61 to achieve a stable engagement between the terminal cover 4 and the housing 6. At the same time, it is ensured that the two terminals 1 pre-fixed by the terminal cover 4 are embedded one by one into the two mounting holes 63 of the housing 6, thus completing the positioning of the terminals 1 in the housing 6.

[0050] Finally, the circuit board 5 and the terminal cover 4 are assembled. Before assembling the circuit board 5 and the terminal cover 4, the thermal sensor 2 pre-fixed on the circuit board 5 is coated with the heat-conducting component 7. The heat-conducting component 7 is evenly coated on the upper end of the thermal sensor 2 to ensure that the coating amount is suitable for the subsequent contact gap with the metal sheet 3. The first snap-fit ​​component 51 on the circuit board 5 is aligned with the first snap-fit ​​hole 431 of the terminal cover 4. When the circuit board 5 is pushed, the first snap-fit ​​rod 511 converges towards the center of the connector 512 to fit the entrance of the first snap-fit ​​hole 431. After it is fully inserted into the cavity, the snap-fit ​​part of the first snap-fit ​​component 51 abuts against the limiting part in the first snap-fit ​​hole 431 to achieve a stable engagement between the circuit board 5 and the terminal cover 4. During this process, the thermal sensor 2 pre-fixed on the circuit board 5 will be positioned synchronously with the circuit board 5 and accurately built into the second receiving groove 44 of the terminal cover 4. The second receiving groove 44 simultaneously reserves space for the heat-conducting component 7 to ensure the subsequent cooperation between the thermal sensor 2, the heat-conducting component 7 and the metal sheet 3.

[0051] The above settings ensure that the heat generated by terminal 1 can be efficiently transferred to the thermal sensor 2, enabling real-time and accurate monitoring of the temperature of terminal 1, and providing support for the safe and reliable operation of the charging dock.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
