Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific implementation methods, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0054] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0055] This embodiment provides a plug-in assembly, including a pole piece 1, a clamping member 2, a connecting member 3 and a limiting member 4. Figure 1 Wherein, the electrode sheet 1 is an electrode sheet on the component requiring power supply, including a positive electrode sheet and a negative electrode sheet, which are connected to an external control component or a power supply component through the positive electrode sheet and the negative electrode sheet to form a current loop inside the component requiring power supply.

[0056] The pole piece 1 is inserted into the clamping member 2, and the two sides of the clamping member 2 are against the two sides of the pole piece 1; the two ends of the pole piece 1 are extended out of the two ends of the clamping member 2, and the two ends of the pole piece 1 extending out of the clamping member 2 are respectively connected to the power supply component and the control component (or power supply component), and the conductive function is realized through the pole piece 1. The pole piece 1 is inserted into the clamping member 2, and the clamping member 2 can form support and protection for both sides of the pole piece 1 to prevent the pole piece 1 from bending and deforming during the plug-in process, thereby causing poor contact between the pole piece 1 and the control component (or power supply component).

[0057] The connector 3 has a slot 321, the pole piece 1 is inserted into the slot 321, and the limiting member 4 is arranged on the slot 321 for abutting against the pole piece 1. The limiting member 4 limits and locks the free end of the pole piece 1 to prevent the pole piece 1 from falling out of the slot 321, thereby improving the plug-in reliability of the plug-in assembly.

[0058] It should be noted that when the plug-in assembly of the present application is used to achieve a connection between two components, the pole piece 1 and the clamping member 2 are arranged on the component requiring power supply, and the connecting member 3 and the limiting member 4 are arranged on the control component or the power supply component. When the pole piece 1 is inserted into the connecting member 3 and the limiting member 4, an electrical connection between the component requiring power supply and the control component (or power supply component) can be achieved.

[0059] It should be noted that the clamping member 2 includes at least two oppositely arranged clamping plates for abutting against the two sides of the pole piece 1. Furthermore, the clamping member 2 can be a cylindrical structure, which can not only realize the support and protection of the two sides of the pole piece 1, but also can be used to realize the circumferential protection of the pole piece 1, such as Figure 1 and Figure 5 shown.

[0060] See also Figure 2 In some embodiments of the present application, the limiting member 4 includes a plurality of limiting springs 41 arranged along the circumference of the slot 321, the limiting springs 41 can be elastically deformed, and there is a first preset distance between two relatively arranged limiting springs 41; along the length direction of the first preset distance, the first preset distance is smaller than the size of the pole piece 1. Specifically, the two relatively arranged limiting springs 41 are arranged in an inverted eight-shaped shape, and the first preset distance is the minimum distance between the two limiting springs 41. When the pole piece 1 is inserted into the slot 321, the limiting springs 41 can be squeezed, and the distance between the two relatively arranged limiting springs 41 becomes larger, and the limiting springs 41 are always pressed against the outer surface of the pole piece 1, and the pole piece 1 is clamped by the elastic force of the limiting springs 41 to prevent the pole piece 1 from coming out of the slot 321.

[0061] It should be noted that, since the pole piece 1 is a flat structure, it is preferred that the limiting spring pieces 41 are arranged on both sides of the length direction of the slot 321. At this time, the first preset distance is less than the thickness of the pole piece 1. The pole piece 1 can be abutted and limited by multiple sets of relatively arranged limiting spring pieces 41, so that the clamping between the pole piece 1 and the slot 321 is more secure. Figure 1 and Figure 2 shown.

[0062] It should be noted that in order to realize the circumferential installation of the limiting spring piece 41 in the slot 321, each limiting spring piece 41 can be fixed one by one on both sides of the slot 321 by welding or screw connection, or multiple limiting members 4 can be integrated on the same mounting frame, and then the mounting frame is connected to the edge of the slot 321. Specifically, in some embodiments of the present application, the limiting member 4 also includes an annular frame 42, and the annular frame 42 is matched with the slot 321. The middle part of the annular frame 42 has a through groove for passing the pole piece 1. The size of the through groove is set according to the size of the pole piece 1 and the size of the slot 321, so that the pole piece 1 can be smoothly inserted into the through groove and the slot 321. Multiple limiting spring pieces 41 and the annular frame 42 are an integrated structure. The limiting spring pieces 41 are connected to the edge of the through groove, and the limiting spring pieces 41 and the annular frame 42 are set at an angle, so that the limiting spring pieces 41 can be bent relative to the annular frame 42 and extend into the interior of the slot 321. Figure 2 shown.

[0063] When manufacturing the limiting member 4, the annular frame 42 and the limiting spring sheet 41 can be integrally formed by stamping and bending, and then the annular frame 42 is installed on the connecting member 3, which can reduce the difficulty of assembling multiple limiting spring sheets 41 and improve the assembly efficiency of the limiting member 4.

[0064] The present application embodiment provides a heating device, including the plug assembly in the above embodiment, and also including a heating core 5 and a controller 6, wherein the heating core 5 and the controller 6 are separable. Figure 3 and Figure 4 As shown. The heating core 5 is a component that needs to be powered, which can convert the electrical energy transmitted by the pole piece 1 into thermal energy. The controller 6 is a control component, which can be detachably connected with the heating core 5 through a plug-in component. This is conducive to the independent production of the heating core 5 and the controller 6. When the heating core 5 and the controller 6 are assembled, the electrical connection between the heating core 5 and the controller 6 is achieved through the plug-in component.

[0065] For details, please refer to Figure 4 and Figure 5 The heating core 5 includes a first shell 51, and a through hole is provided on the first shell 51 for inserting the pole piece 1, so that the pole piece 1 can extend into the first shell 51 through the through hole and be connected with the heating component 52. The clamping member 2 is provided on the first shell 51, and the clamping member 2 is a cylindrical structure, one end of the clamping member 2 is connected with the through hole, and the pole piece 1 passes through the through hole and the clamping member 2 in sequence, and can be used to connect with the controller 6.

Figure 3 shown.

[0069] Each heating component 52 is provided with two electrodes 1, which are used to serve as the positive electrode and the negative electrode of the heating component 52, so as to form a current inside the heating component 52. The plurality of electrodes 1 are provided in a one-to-one correspondence with the plurality of clamping members 2, such as Figure 5 As shown, each pole piece 1 can be protected by a clamping member 2 .

[0070] It should be noted that, in the above-mentioned embodiment, the plurality of clamping members 2 may be independent of each other, or two or more adjacent clamping members 2 may be configured as an integrated structure, such as Figure 8 Specifically, the clamping member 2 is made of insulating material, and more than two clamping members 2 can be prepared at the same time by integral injection molding or the like, which is conducive to improving the preparation efficiency of the clamping member 2. Preferably, the two clamping members 2 used to cooperate with the two pole pieces 1 of the same heating component 52 can be used as an integrated structure, which is conducive to the modular production of the clamping member 2.

[0071] In some embodiments of this application, please refer to Figure 3 , Figure 4 and Figure 5 The heating component 52 includes a heating tube 521 and heat dissipation fins 522. A plurality of heat dissipation fins 522 are sequentially arranged along the length direction of the heating tube 521 to quickly dissipate the heat generated by the heating tube 521 and improve the heat dissipation efficiency of the heating component 52. The heating tube 521 is electrically connected to the electrode 1 to generate current inside the heating tube 521 and convert electrical energy into heat energy through the heating tube 521.

[0073] In the above embodiment, in order to accurately insert the pole piece 1 into the slot 321 and the through slot of the stopper 4, the pole piece 1 needs to be guided during the plugging process. However, the pole piece 1 is a thin sheet structure and is easily squeezed and deformed during the guiding process.

[0074] To solve the above problems, in some embodiments of the present application, please refer to Figure 6 and Figure 7 The connecting member 3 includes a first connecting plate 31, and a guide groove 311 is provided on the first connecting plate 31. The projection of the guide groove 311 along the insertion direction of the pole piece 1 completely covers the periphery of the slot 321 and the stopper 4. Figure 7 When the heating core 5 is plugged into the controller 6, the pole piece 1 passes through the guide groove 311, and then the clamping member 2 is inserted into the guide groove 311. The inner wall of the guide groove 311 matches the outer wall of the clamping member 2, and can guide the clamping member 2, so that the pole piece 1 inserted in the clamping member 2 is accurately inserted into the slot 321 and abuts against the limiting spring sheet 41.

[0075] The controller 6 includes a controller housing, at least a portion of which is configured as a first connecting plate 31 , so that the pole piece 1 and the clamping member 2 can be guided by the guide groove 311 on the first connecting plate 31 when passing through the controller housing.

[0076] In some embodiments of this application, please refer to Figure 3 , Figure 4 and Figure 6 The controller housing includes a plurality of side plates sequentially arranged along the circumference of the first connecting plate 31. The plurality of side plates are connected to the first connecting plate 31 to form a mounting groove having a connecting opening. The first connecting plate 31 is arranged opposite to the connecting opening so that the first connecting plate 31 is located at the bottom of the mounting groove. A connecting end plate 511 is provided on the first housing 51 of the heating core 5. A plurality of clamping members 2 are arranged on the connecting end plate 511. The mounting groove is matched with the connecting end plate 511 to achieve concave-convex matching between the connecting end plate 511 and the mounting groove, so that the clamping member 2 can quickly achieve alignment with the guide groove 311, thereby achieving assembly positioning of the controller housing and the first housing 51, which is beneficial to improving the assembly efficiency between the controller 6 and the heating core 5.

[0077] Specifically, the controller housing includes a first side plate 611 and a third side plate 613 that are arranged opposite to each other, and also includes a second side plate 612 connected to both ends of the first side plate 611 and the third side plate 613. A mounting groove with a connecting opening is formed by enclosing the first connecting plate 31, the first side plate 611, the second side plate 612 and the third side plate 613. The pole piece 1, the clamping member 2 and the connecting end plate 511 can be inserted from the connecting opening of the mounting groove, and the clamping member 2 can extend into the guide groove 311 and be guided by the guide groove 311, so that the pole piece 1 can be inserted into the slot 321 behind the first connecting plate 31.

[0078] A plurality of first connection parts 514 are provided on the connection end plate 511, and a plurality of second connection parts 615 corresponding to the positions of the first connection parts 514 are provided on the first side plate 611. When the connection end plate 511 is inserted into the installation slot, the first connection parts 514 and the second connection parts 615 can be connected by bolts, thereby realizing a fixed connection between the first housing 51 and the controller housing. The fixed connection is a detachable connection, which facilitates the separation of the heating core 5 and the controller 6.

[0079] In the above embodiment, since the controller 6 generates heat during use, if the heat accumulates inside the controller housing, it will cause damage to the components inside the controller housing.

[0080] To solve the above problems, in some embodiments of the present application, please refer to Figure 3 and Figure 6 , at least one side panel is provided with a heat dissipation structure 614; specifically, the heat dissipation structure 614 can be a heat dissipation hole or a heat sink, but the heat dissipation efficiency of the heat dissipation hole is low, and external dust and impurities can easily enter the controller 6 through the heat dissipation hole. Therefore, in some preferred embodiments of the present application, the heat dissipation structure 614 is arranged on the first side panel 611, and the heat dissipation structure 614 includes a plurality of heat sinks, which can increase the heat dissipation area of ​​the controller housing through the heat sinks. In order to realize the utilization of the heat energy generated by the controller 6, the heat sink extends to the heat dissipation opening, which can further heat the air flowing out of the heat dissipation opening, and can increase the air temperature at the heat dissipation opening, which is conducive to realizing the waste heat utilization of the controller 6.

There is a second preset distance between the first connector plate 31 and the second connector plate 32. The second preset distance is greater than the depth of the clamping member 2 inserted into the first connector plate 31, which can avoid the bottom of the clamping member 2 from colliding with the second connector plate 32 during insertion. The slot 321 is arranged on the second connector plate 32. Preferably, there is a spacing of 1 to 5 mm between the bottom of the clamping member 2 and the upper surface of the second connector plate 32. When the pole piece 1 is inserted into the slot 321 of the second connector plate 32, the clamping member 2 is located above the second connector plate 32. In order to realize the clamping of the pole piece 1 through the limiter 4, the limiter 4 needs to be arranged on the second connector plate 32. The second connector plate 32 is provided with a positioning structure 322 for cooperating with the limiter 4, which can be used to realize the positioning and installation of the limiter 4.

[0082] In some embodiments of this application, please refer to Figure 1 and Figure 2 The positioning structure 322 includes a positioning groove, and the limiting member 4 includes a plug-in portion 43 arranged to match the positioning groove. When the plug-in portion 43 is inserted into the positioning groove, the limiting member 4 is positioned on the second connecting plate 32. The fixed connection between the limiting member 4 and the second connecting plate 32 can be achieved by welding, clamping, etc., to prevent the limiting member 4 from being pulled out by the pole piece 1 when the heating core 5 is separated from the controller 6.

[0083] It should be noted that the plug-in portion 43 and the annular frame 42 can be integrally formed by stamping, bending and other processes, which can reduce the difficulty of manufacturing the limiter 4 and facilitate the mass production of the limiter 4. Two plug-in portions 43 are provided in the diagonal area of ​​the annular frame 42, and the two plug-in portions 43 can cooperate with the second connecting plate 32 to realize the rapid positioning of the entire limiter 4, such as Figure 2 shown.

[0084] In the above embodiment, the electrical connection of the pole piece 1 can be achieved by setting a conductive element inside the slot 321, or by directly conducting current to the pole piece 1 through the limiting spring 41. In some preferred embodiments of the present application, the limiting member 4 is a conductive member, and the second connecting plate 32 is a circuit board inside the controller 6, which can simplify the setting of the conductive circuit inside the controller 6 and conveniently achieve the electrical connection between the pole piece 1 and the heating core 5.

[0085] In some embodiments of the present application, in order to facilitate the installation of internal components of the controller 6 such as circuit boards, the controller housing is a split housing. Specifically, the controller housing includes a second housing 61 and a third housing 62, wherein the second housing 61 includes a first connecting plate 31, a first side plate 611, a second side plate 612, and a third side plate 613. After components such as circuit boards are arranged inside the third housing 62, the second housing 61 is covered on the third housing 62, and a sealing layer is filled at the connection gap between the second housing 61 and the third housing 62, so that the connection between the second housing 61 and the third housing 62 can be sealed.

[0086] In order to realize the power supply control of the heating core 5 through the controller 6, the controller 6 also includes a low-voltage connector 63 and a high-voltage connection harness 64. The low-voltage connector 63 and the high-voltage connection harness 64 are both electrically connected to the circuit board (i.e., the second connection board 32), and can supply power to the controller 6 and the heating core 5 according to the control signal. Specifically, the low-voltage connector 63 and the high-voltage connection harness 64 are arranged to extend out of the third housing 62, and their positions can be arranged according to actual needs. Specifically, the position of the low-voltage connector on the third housing 62 can be adjusted and designed in terms of position and orientation based on the layout requirements, and the length of the high-voltage connection harness 64 and the position of the outlet can be adjusted and designed based on the space restrictions of the entire vehicle layout and the requirements of the entire vehicle connector.

[0087] An embodiment of the present application proposes a HVAC system, including the heating device in the above embodiment, wherein the heating core 5 and the controller 6 are separable, so as to facilitate the independent production of the heating core 5 and the controller 6, so that the heating core 5 can be manufactured together with the HVAC box in the HVAC system, and the controller housing can be adjusted according to its installation position in the HVAC system and the shape of the layout space.

[0088] In the prior art, when an air-heating electric heater is used to heat the passenger compartment, the air-heating electric heater is often assembled inside the HVAC to achieve heating of the passenger compartment. However, since the air-heating electric heater is installed on the HVAC box, and the air-heating electric heater and the HVAC are arranged together in the lower area of ​​the dashboard in the passenger compartment, the layout space of the HVAC system is relatively compact. The controller is arranged at the outer boundary of the HVAC, which will be affected by the layout space and even the shape boundary; while the heating core and controller of the existing automotive air-heating electric heater are an integral structure, which will result in the same air-heating electric heater core structure design for different models of the same platform, but the controller structure shape is different, resulting in differences in the air-heating electric heater assembly for each model, resulting in a variety of air-heating electric heating states, which is conducive to product production and management.

[0089] In order to solve the above problems, the embodiment of the present application proposes a car, which is provided with the HVAC system in the above embodiment. Since the heating core 5 and the controller 6 are separable, the heating core 5 can be designed as an independent component according to the internal space limitation of the HVAC, and supplied as a whole with the HVAC, and is not affected by the layout boundary and connection requirements of the whole vehicle. The heating core 5 can be uniformly produced and applied to different models, and produced and managed as a universal component.

[0090] The connection part of the controller housing with the whole vehicle and the shape of the housing can be adapted and adjusted based on the layout boundary and connection requirements of the whole vehicle, and only the controller 6 corresponding to each vehicle type needs to be managed separately. When adjusting the design of the controller 6, it is only necessary to ensure that the position design of the parts matching with the heating core 5, such as the installation groove, the first connecting plate 31 and the second connecting plate 32, is fixed. The adjustment design of other parts (such as the third housing 62, the low-voltage connector 63 and the high-voltage connecting harness 64, etc.) will not affect the production status of the heating core 5.

[0091] Specifically, the controller housing is also provided with a third connection portion 616 and a fourth connection portion 617 for connecting to the vehicle body, and the positions of the third connection portion 616 and the fourth connection portion 617 on the controller housing can be adjusted and designed as needed. The second housing 61 is formed by die-casting or casting of metal materials, and the heat dissipation structure 614, the third connection portion 616 and the fourth connection portion 617 are prepared by machining after die-casting. The third housing 62 is formed by sheet metal stamping, and its shape can be adjusted and designed as needed.

[0092] In some preferred embodiments of the present application, the above-mentioned car is an electric car. In the absence of an engine, the passenger compartment can be heated by a heating device installed inside the HVAC system.

[0093] The present application inserts the pole piece 1 in the plug assembly into the clamping member 2, and supports and protects the pole piece 1 through the clamping member 2, thereby preventing the pole piece 1 from bending and deforming during the plugging process, and preventing the pole piece 1 from having poor contact after plugging. A stopper 4 for abutting against the pole piece 1 is provided on the connector 3, which can improve the plugging reliability between the pole piece 1 and the slot 321 in the connector 3, and prevent the pole piece 1 from falling out of the slot 321.

[0094] The plug-in assembly of the present application is applied to a heating device, so that the heating core 5 and the controller 6 of the heating device can be separated, which is conducive to the independent production of the heating core 5 and the controller 6, and is conducive to the production and management of heating devices of different vehicle models.

[0095] The above embodiments are only preferred embodiments for fully illustrating the present application, and the protection scope of the present application is not limited thereto. Any equivalent substitution or change made by a person skilled in the art based on the present application is within the protection scope of the present application.
