Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and more specifically, to a contact switch assembly and a refrigerator. Background Technology

[0002] With economic development, refrigerators, as a common food preservation device, are ubiquitous in daily life. In particular, electronically controlled refrigerators are becoming increasingly popular due to their intelligent features, giving them a high degree of competitiveness in the refrigerator market.

[0003] In related technologies, an electrically controlled refrigerator includes a control board, a display board, a cabinet, and a door. The cabinet and the door are connected together by hinges to ensure the overall stability and durability of the refrigerator and to allow the door to be opened relative to the cabinet. The control board is usually located on the refrigerator cabinet, and the display board is usually located on the refrigerator door. Generally, the control board on the cabinet and the display board on the door are electrically connected by a communication line passing through the shaft hole of the hinge shaft to realize information exchange between the control board and the display board.

[0004] However, the above-mentioned wire harness connection method is time-consuming and requires excessively long wire harnesses for docking, resulting in low production line installation efficiency. When the product function is more complex, the number of wire harnesses will increase accordingly, leading to components that are too thick or wire harness terminals that are too large, making it impossible to pass through the shaft hole. This greatly limits the wire harness connection method and thus affects the performance of the electric refrigerator. Utility Model Content

[0005] The main objective of this invention is to provide a contact switch assembly and a refrigerator, aiming to solve the technical problem that the wiring harness between the control board and the display board is connected by passing through the shaft hole of the hinge shaft, which has significant limitations.

[0022] In one possible implementation, the telescopic portion further includes:

[0023] A door trim strip is installed on the refrigerator door. The door trim strip has a first fixing hole and a second wire hole. The fixing box has a second fixing hole. The first fixing hole and the second fixing hole are assembled and connected.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0042] In the description of this utility model, it should be noted that the terms "first", "second", "third", etc. are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.

[0043] In the description of this utility model, it should be noted that the terms "vertical", "horizontal", "above", "below", "upper side", "top surface" and "bottom surface" are all based on the corresponding view or the orientation in which the refrigerator is placed when it is in normal use.

[0044] Please see Figures 1-3 This utility model provides a contact switch assembly, which includes a telescopic part 2 and a base part 1.

[0045] The telescopic part 2 is installed on the refrigerator door, and the telescopic part 2 is electrically connected to the display panel via a wiring harness.

[0046] The base part 1 is disposed on the refrigerator body. The base part 1 includes a base platform 13. One side of the base platform 13 is electrically connected to the control board through a wiring harness. When the refrigerator door contacts the refrigerator body, the other side of the base platform 13 contacts the telescopic part 2, so that a passage is formed between the control board and the display board.

[0047] The telescopic part 2 and the base part 1 are matched in pairs. For example, the control board can be set on the top or back of the refrigerator body, the display board can display the refrigerator temperature or related operation function keys, and the control board can control the internal system of the refrigerator and control the display board.

[0048] The wiring harness between the refrigerator door and the refrigerator body plays a crucial role. Specifically, these wiring harnesses serve as an important bridge connecting various sensors, controllers, lighting devices on the refrigerator door, and the power and control systems inside the refrigerator body, ensuring the normal operation of all refrigerator functions.

[0049] Specifically, the refrigerator door is typically equipped with devices such as temperature sensors, defrost heaters, door open / close sensors, and LED lights. These devices need to communicate and transmit data with the control system inside the refrigerator via a wiring harness. The wiring harness contains multiple finely arranged wires, each of which undertakes a specific signal transmission or power supply task.

[0050] For example, the temperature sensor transmits the temperature information inside the refrigerator door to the control system in real time via a wiring harness. The control system then adjusts the operating status of the refrigeration system based on this information to maintain a constant temperature inside the refrigerator.

[0051] The wiring harness connected to the base platform 13 can be connected to the communication line of the refrigerator body, and the communication line of the refrigerator body can then be connected to the control board, thereby realizing the electrical connection between the base platform 13 and the control board.

[0052] When designing wiring harnesses, several technical factors need to be considered to ensure their reliability and durability. First, the harness needs to have good flexibility to accommodate the bending and stretching that occurs during frequent opening and closing of the refrigerator door. Second, the outer sheath material of the harness needs to have excellent wear resistance, oil resistance, and chemical corrosion resistance to prevent insulation damage or wire aging caused by environmental factors during long-term use. Furthermore, the arrangement and fixing method of the wiring harness also need to be carefully designed to avoid vibration or noise during refrigerator operation.

[0053] With the continuous development of smart home technology, modern refrigerators are increasingly integrating more intelligent functions. This requires the wiring harness between the refrigerator door and the refrigerator body to not only meet basic signal transmission and power supply needs, but also support high-speed data transmission and complex communication protocols. Therefore, more advanced technologies and materials need to be adopted in the design and manufacturing of the wiring harness to meet the needs of the intelligent development of refrigerators.

[0054] In summary, the wiring harness located between the refrigerator door and the refrigerator body is crucial. However, in related technologies, the wiring harness between the control board and the display board is connected by passing through the hinge shaft hole, which presents significant technical limitations.

[0055] In this embodiment, the telescopic part is disposed in the refrigerator door. During refrigerator assembly, the telescopic part is connected to the refrigerator's display panel via a wiring harness. That is, the telescopic part is connected to the display panel located on the refrigerator door via a wiring harness, but is not connected to any related components located on the refrigerator body via a wiring harness.

[0056] Similarly, the base part 1 is disposed in the refrigerator body. During refrigerator assembly, the base part 1 is connected to the control board of the refrigerator through a wiring harness. That is, the base part 1 is connected to the control board located on the refrigerator body through a wiring harness, but is not connected to the relevant components located on the refrigerator door through a wiring harness.

[0057] Based on the above description of the base part 1 and the telescopic part, it can be seen that there is no physical wiring harness connection between the base part 1 and the telescopic part. That is, the display panel and the control panel do not need to be connected by a wiring harness passing through the hinge shaft hole. However, when the refrigerator is closed, the base platform 13 of the base part 1 makes electrical contact with the contact component in the telescopic part, thereby achieving a contact-type switching effect. That is, when the refrigerator door is in contact with the refrigerator body, the base part 1 is in contact with the telescopic part, so that a passage is formed between the control panel and the display panel.

[0058] In this way, by independently setting the base part 1 and the telescopic part 2, the display panel and the control panel do not need to be connected by a wire harness passing through the hinge shaft hole. This makes the wire harness connection method more time-saving, eliminates the need to reserve excessively long wire harnesses, facilitates docking, and improves the efficiency of production line installation. Even when the product function is more complex, it is not easily limited by the increase in the number of wire harnesses, thereby improving the performance and market competitiveness of the corresponding refrigerator.

[0059] Based on the above design, this embodiment allows the control board and the display board to form a passage by having the other side of the base 13 contact the telescopic part 2. This eliminates the need for a wire harness passing through the hinge shaft hole to connect the display board and the control board, thereby reducing the limitations on the wire harness setup between the display board and the control board and improving the performance of the corresponding refrigerator.

[0060] In some embodiments, see Figures 3-6 The base portion 1 also includes a pre-embedded box 11 and a base body 12.

[0061] The embedded box 11 is installed on the refrigerator body. The embedded box 11 has a first opening 111 on the side near the telescopic part 2 and a first wire hole 112 on the side away from the telescopic part 2. The wire harness that is electrically connected to the base platform 13 passes through the first wire hole 112 and is electrically connected to the control board.

[0062] The base body 12 is disposed in the pre-embedded box 11, and the side of the base body 12 near the telescopic part 2 is connected to the base platform 13 through the first opening 111.

[0063] The base body 12 and the base platform 13 are used to form a passage with the telescopic part 2. If the base body 12 and the base platform 13 are directly installed in the refrigerator body, the wiring may be affected by unnecessary factors. Therefore, this embodiment also provides the embedded box 11 to house the base body 12 and the base platform 13, thereby completing the storage of the base body 12 and the base platform 13 and making it easier to install the base body 12 and the base platform 13.

[0064] A portion of the base body 12 extends into the first opening 111 and is in contact with the base platform 13. The base body 12 can increase the stability of the base platform 13. The base platform 13 has good conductivity and is moisture-proof and corrosion-resistant. In this way, not only can the electrical connection between the base platform 13 and the control board and the telescopic part 2 be improved, but the service life of the base platform 13 can also be improved.

[0065] In some embodiments, please refer again Figures 3-6 The base part 1 also includes a box beam 14, which is disposed on the refrigerator body and has a plurality of first mounting holes 141.

[0066] The pre-embedded box 11 includes a plurality of first claws 113, each of which corresponds to a plurality of first mounting holes 141, and the first claws 113 engage with the first mounting holes 141.

[0067] The box beam 14 can be fixedly connected to the refrigerator body. The embedded box 11 is set on the box beam 14. Specifically, the embedded box 11 can be set on the box beam 14 by engaging the first claw 113 with the first mounting hole 141. This makes it easier to connect the embedded box 11 and the box beam 14.

[0068] The multiple first claws 113 correspond one-to-one with the multiple first mounting holes 141, and the first claws 113 engage with the corresponding first mounting holes 141, which can improve the stability of the connection between the embedded box 11 and the box beam 14.

[0069] In some embodiments, please refer again Figures 3-6 The pre-embedded box 11 also includes a second claw 115 and a clamping body 114 arranged opposite to each other. The box beam 14 is also provided with a snap-fit ​​protrusion 142, which is clamped between the second claw 115 and the clamping body 114.

[0070] By engaging the snap-fit ​​protrusion 142 with the second snap-fit ​​claw 115 and the clamping body 114, the stability of the connection between the embedded box 11 and the box beam 14 can be further improved.

[0071] Optionally, the second claw 115 and the clamping body 114 can be configured in multiple sets, and the snap-fit ​​protrusions 142 can be configured in multiple sets. The multiple sets of the second claw 115 and the clamping body 114 correspond one-to-one with the multiple snap-fit ​​protrusions 142, and each set of the second claw 115 and the clamping body 114 snaps into the corresponding snap-fit ​​protrusion 142. In this way, the stability of the connection between the embedded box 11 and the box beam 14 can be further improved.

[0072] In some embodiments, see Figure 3 , Figure 4 and Figure 7 The telescopic part 2 includes a fixed box 21, a telescopic column 22, and a fixed block 23.

[0073] The fixing box 21 is installed on the refrigerator door, and the fixing box 21 has a second opening 211 on the side near the base part 1.

[0074] The telescopic column 22 is disposed inside the fixed box 21. When the refrigerator door is in contact with the refrigerator body, part of the telescopic column 22 passes through the second opening 211 and makes electrical contact with the base platform 13.

[0075] The fixing block 23 is disposed inside the fixing box 21. The side of the fixing block 23 near the base part 1 is in contact with the telescopic column 22. The side of the fixing block 23 away from the base part 1 is provided with a wire harness hole 231. The wire harness disposed on the wire harness hole 231 is electrically connected to the display panel.

[0076] In this embodiment, the wiring harness connected to the fixing block 23 can be connected to the communication line of the refrigerator door, and the communication line of the refrigerator door can be connected to the display panel, thereby realizing the electrical connection between the fixing block 23 and the display panel.

[0077] The telescopic column 22 and the fixing block 23 can be placed inside the fixing box 21 to store the telescopic column 22 and the fixing block 23, thereby making it easier to set up the telescopic column 22 and the fixing block 23.

[0078] Both the telescopic column 22 and the fixing block 23 are benign conductors, dustproof and corrosion-resistant, and maintain permanent elasticity. When the refrigerator door contacts the refrigerator body, part of the telescopic column 22 passes through the second opening 211 and makes electrical contact with the base platform 13. The wiring harness connecting the control board and the base platform 13 is connected to the wiring harness connecting the fixing block 23 and the display board, thereby connecting the display board and the control board. A "contact switch" is formed between the base platform 13 and the telescopic column 22. In this way, the display board and the control board do not need to be connected through the wiring harness passing through the hinge shaft hole to make the display board and the control board mutually conductive.

[0079] Optionally, there are multiple telescopic columns 22 and multiple base platforms 13, with each telescopic column 22 corresponding to one of the multiple base platforms 13. The center lines of the telescopic columns 22 and the base platforms 13 are aligned, thereby ensuring better contact between the telescopic columns 22 and the base platforms 13.

[0080] In some embodiments, please refer again Figure 4 The telescopic column 22 is equipped with a compression spring 25. When the refrigerator door contacts the refrigerator body, the compression spring 25 is in a compressed state.

[0081] When the refrigerator door contacts the refrigerator body, the base platform 13 contacts the telescopic column 22, the display panel and the control panel are in a connected state, and the compression spring 25 is in a compressed state; when the refrigerator door does not contact the refrigerator body, the display panel and the control panel are in a disconnected state, the base platform 13 and the telescopic column 22 do not contact, and the compression spring 25 is usually in an uncompressed state.

[0082] In some embodiments, see Figure 4 and Figure 8 The telescopic column 22 includes a spherical surface 221 on the side near the base platform 13, and the base platform 13 includes a contact platform 131 on the side near the telescopic column 22. When the refrigerator door contacts the refrigerator body, the spherical surface 221 makes electrical contact with the contact platform 131.

[0083] That is, the part of the telescopic column 22 near the base platform 13 is a cylindrical sphere, and the part of the telescopic column 22 away from the base platform 13 is a cylinder.

[0084] When the refrigerator door comes into contact with the refrigerator body, the spherical surface 221 and the contact platform 131 abut against each other, making it easier to achieve communication between the base platform 13 and the telescopic column 22, and further making it easier to achieve communication between the display panel and the control panel, and ultimately making it easier to achieve communication between the refrigerator body and the refrigerator door.

[0085] In some embodiments, see Figure 4 and Figure 9 The telescopic part 2 also includes a door trim strip 24, which is installed on the refrigerator door. The door trim strip 24 has a first fixing hole 241 and a second wire hole 242. The fixing box 21 has a second fixing hole 212. The first fixing hole 241 and the second fixing hole 212 are assembled and connected. The wire harness connected to the fixing block 23 passes through the second wire hole 242 and is electrically connected to the display panel.

[0086] The door trim 24 can be fixedly connected to the refrigerator door. The first fixing hole 241 and the second fixing hole 212 are assembled and connected. For example, the second fixing hole 212 has an outward protrusion. The first fixing hole 241 and the protrusion of the second fixing hole 212 are assembled and connected to each other, so that the connection between the fixing box 21 and the door trim 24 can be realized. The second wire hole 242 is provided on the door trim 24, which makes it easier for the wire harness connected to the fixing block 23 to pass through the second wire hole 242 and be electrically connected to the display panel.

[0087] In some embodiments, please refer again Figure 4 The length of the telescopic column 22 extending out of the fixed box 21 is greater than the distance between the refrigerator door and the refrigerator body when the refrigerator is closed.

[0088] In this embodiment, because the length of the telescopic column 22 extending out of the fixing box 21 is greater than the distance between the refrigerator door and the refrigerator body when the refrigerator is closed, the telescopic column 22 and the base platform 13 can abut against each other when the refrigerator door and the refrigerator body are in contact, thereby realizing the connection between the display panel and the control panel.

[0089] In summary, there is no physical wiring harness connection between the base portion 1 and the telescopic portion 2 in this application. That is, the display panel and the control panel do not need to be connected by a wiring harness passing through the hinge shaft hole. However, when the refrigerator is closed, the base platform 13 of the base portion 1 makes electrical contact with the contact component in the telescopic portion, thereby achieving a contact-type switching effect. That is, when the refrigerator door contacts the refrigerator body, the base portion 1 contacts the telescopic portion 2, so that a passage is formed between the control panel and the display panel.

[0090] Thus, by independently setting the base part 1 and the telescopic part, the display panel and the control panel do not need to be connected by a wire harness passing through the hinge shaft hole. This makes the wire harness connection more time-saving, eliminates the need for excessively long wire harnesses, facilitates docking, and increases production line installation efficiency. The communication connection between the control panel and the display panel is automatically realized through the opening and closing of the refrigerator door. Even when the product function is more complex, it is not easily limited by the increase in the number of wire harnesses. The component structure is simple, and the overall installation process is also simpler, thereby improving the performance and market competitiveness of the corresponding refrigerator.

[0091] In some embodiments, please refer again Figures 1-4 The present invention also provides a refrigerator, wherein the refrigerator 3 includes the contact switch assembly described in this application.

[0092] The switch assembly includes a telescopic part 2 and a base part 1. The telescopic part 2 is disposed on the refrigerator door and is electrically connected to the display panel via a wiring harness. The base part 1 is disposed on the refrigerator body and includes a base platform 13. One side of the base platform 13 is electrically connected to the control board via a wiring harness. When the refrigerator door contacts the refrigerator body, the other side of the base platform 13 contacts the telescopic part 2, thereby forming a passage between the control board and the display panel.

[0093] Since the refrigerator 3 includes the contact switch assembly described in this application, by independently setting the base part 1 and the telescopic part in the refrigerator 3, the display panel and the control panel do not need to be connected by a wire harness passing through the hinge shaft hole. This makes the wire harness connection method more time-saving, eliminates the need to reserve excessively long wire harnesses, facilitates docking, and improves production line installation efficiency. The communication connection between the control panel and the display panel is automatically realized through the opening and closing of the refrigerator door. Even when the product function is more complex, it is not easily limited by the increase in the number of wire harnesses, thereby improving the performance and market competitiveness of the refrigerator 3.

[0094] The above are merely various embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
