They can quickly and accurately measure human body temperature. Compared with traditional mercury glass thermometers, they have the advantages of convenient reading, short measurement time, high measurement accuracy, memory function, and beeping prompts. In particular, electronic thermometers do not contain mercury and are harmless to the human body and the surrounding environment, making them especially suitable for use in homes, hospitals, and other places.
[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Utility Model Content
[0004] The inventors discovered that the basic structure of an electronic thermometer includes a temperature sensor, a measuring rod, a display screen, a switch, buttons, and a battery cover. To secure the battery cover, it is typically fastened to a separate component using screws. To facilitate the assembly of the internal components, an end cap is attached to the thermometer's tail. However, this method requires two components for assembly, resulting in higher component costs and longer assembly time.
[0005] To address at least one of the aforementioned problems or other similar issues, embodiments of this application provide an electronic product that incorporates a screw-locking structure in the end cap, ensuring the end cap can be fixed within the housing. This structure reduces one component, shortens assembly time, lowers assembly defect rate, and consequently reduces costs.
[0006] According to a first aspect of the present application, an electronic product is provided, including a housing, an end cap fixed to one end of the housing, and a side cap fixed to the side of the housing. The end cap has a fixing portion, and the side cap is fixed to the fixing portion of the end cap by a fixing member.
[0007] In some embodiments, a first hole is provided on the side of the fixing portion facing the side cover; a second hole is provided on the side cover; the fixing member extends through the second hole to the first hole, so that the side cover is fixed to the end cover.
[0008] In some embodiments, the end cap further has an end portion and a connecting portion connecting the fixing portion and the end portion, wherein when the end cap is inserted into the housing, the connecting portion deforms, causing the fixing portion to be fitted into the housing.
[0009] In some embodiments, the fixing part has a protrusion around the first hole on the side facing the side cover. When the end cover is inserted into the housing, the protrusion engages with the housing, thereby fixing the end cover to the housing.
[0010] In some embodiments, the front end of the protrusion is arc-shaped to facilitate the insertion of the end cap; the rear end of the protrusion is straight, and after the end cap is inserted into the housing, the rear end of the protrusion engages with the housing to provide a limiting function.
[0011] In some embodiments, the end cap has a guide portion extending along the extension direction of the housing, which guides the insertion of the end cap along the inner wall of the housing when the end cap is inserted into the housing.
[0012] In some embodiments, the end of the guide portion is provided with a claw portion, which limits and / or fixes the components inside the housing.
[0013] In some embodiments, at least one corner of the end of the claw is a chamfered structure, which serves as a guide to prevent interference with internal components when the end cap is inserted into the housing.
[0014] In some embodiments, the guide portion has a protrusion on its side. When the end cap is inserted into the housing, the protrusion is embedded in a recess on the inner wall of the housing, serving as a pre-fixing and limiting function.
[0015] In some embodiments, the end cap has a groove that is arranged around the entire circle, and a sealing ring is disposed in the groove. When the end cap is inserted into the housing, the sealing ring abuts against the inner wall of the housing to achieve a sealing effect.
[0016] In some embodiments, a third hole is provided on the side of the end cap to prevent deformation after the product is formed.
[0017] In some embodiments, the electronic product is an electronic thermometer, the end cap is the cap or tail cap of the electronic thermometer, and the side cover is the battery cover of the electronic thermometer.
[0018] One of the beneficial effects of the embodiments of this application is that by designing a screw-locking structure in the end cap of an electronic product (such as an electronic thermometer) while ensuring that the end cap can be fixed in the housing, a part can be reduced, assembly time can be shortened, assembly defect rate can be reduced, and thus cost can be reduced.

[0040] The embodiments of this application will now be described with reference to the accompanying drawings.
[0041] This application provides an electronic product. This electronic product can be an electronic thermometer, but this application is not limited to this. The electronic product can also be other electronic products with a casing, end caps, and side caps, and where there is a need to secure the side caps, such as various remote controls, etc. The following description uses an electronic thermometer as an example to illustrate the electronic product of this application.
[0042] Figure 1 This is a schematic diagram of an electronic thermometer according to an embodiment of this application, showing the condition of one side surface of the electronic thermometer; Figure 2 This is another schematic diagram of an electronic thermometer according to an embodiment of this application, showing the condition of the other side surface of the electronic thermometer.
[0043] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the electronic thermometer 10 includes a housing 11, an end cap 12, and a side cap 13. The end cap 12, for example, is the tail cap or end cap of the electronic thermometer, located at the end opposite to the end where the temperature-sensing head (i.e., probe) S of the electronic thermometer 10 is located; the side cap 13, for example, is the battery cover of the electronic thermometer 10. Furthermore, as... Figure 1 As shown, the electronic thermometer 10 also has a display screen 14, buttons 15, etc. This application does not limit the setting position and implementation method of these features; for details, please refer to relevant technologies.
[0044] Figure 3 This is a schematic diagram of end cap 12. Figure 4 This is a schematic diagram of the side cover 13. Figure 5 This is a schematic diagram of the outer casing 11. Figure 6 This is a cross-sectional view of a portion of the assembled electronic thermometer 10.
[0045] In the embodiments of this application, such as Figure 3 and Figure 6 As shown, the end cap 12 has a fixing part 121, and the side cap 13 is fixed by a fastener S (see Figure 12). Figure 2 The fixing part 121 is fixed to the end cap 12. Thus, by designing a structure on the end cap 12 of the electronic thermometer to fix it to the side cap 13, the number of parts is reduced, the assembly time is shortened, the assembly defect rate is reduced, and the cost is reduced compared to fixing the side cap to a separate part inside the housing.
[0046] In this embodiment, the method of fixing the side cover 13 to the fixing part 121 is not limited. In some possible implementations, such as Figure 3 , Figure 4 and Figure 6As shown, the fixing part 121 has a first hole H1 on the side facing the side cover 13, and the side cover 13 has a second hole H2. The fixing member S extends through the second hole H2 to the first hole H1, so that the side cover 13 is fixed to the end cover 12.
[0047] In the above implementation, the fastener S is, for example, a screw. That is, the side cover 13 is fixed to the end cover 12 by means of thread. Thus, the side cover 13 can be fixed with a simple structure. Since the side cover 13 is fixed to the end cover 12 instead of being a separate part set inside the housing 11, the number of parts is reduced and the installation steps are simplified.
[0048] The above are just examples, and this application is not limited to them. The fastener S can also be other structures, such as a snap-fit component. The fixing part 121 on the end cover 12 is a component that cooperates with the snap-fit component. Thus, the side cover 13 can be fixed to the end cover 12 by snap-fit.
[0049] In some embodiments, such as Figure 3 and Figure 6 As shown, after assembly, the fixing part 121 on the end cap 12 is located inside the outer casing 11. Thus, the side cover 13 can be fixed to the end cap 12 inside the outer casing 11 by the fixing member S. This is not only simple to implement, but also does not occupy the external space of the electronic thermometer 10. This application is not limited to this; the fixing part 121 can also be located outside the outer casing 11, as long as it can be fixed to the end cap 12 by the fixing member S.
[0050] In some embodiments, such as Figure 3 and Figure 6 As shown, the end cap 12 also has an end portion 122 and a connecting portion 123 that connects the fixing portion 121 and the end portion 122. The thickness of the connecting portion 123 (i.e., Figure 6 The length in the Y direction shown is less than the thickness of the fixing part 121. Therefore, when the end cap 12 is inserted into the housing 11, the connecting part 123 can deform so that the fixing part 121 is assembled into the housing 11.
[0051] This application does not impose any restrictions on the placement of the connecting part 123. Figure 6 The connecting portion 123 is shown on the side of the fixing portion 121 away from the side cover 13 (i.e., the fixing portion 121). Figure 6 In the case where the upper side is shown, the connecting part 123 can also be located on the side of the fixing part 121 near the side cover 13 (that is, on the side of the fixing part 121). Figure 6 It is provided on the lower side as shown, or at a position near the middle of the fixing part 121 (i.e., the fixing part 121). Figure 6 (The middle position in the Y direction shown) is set, etc.
[0052] This application specifies the length of the connecting portion 123 (i.e.) Figure 6 The length in the X direction shown is not limited, and the design is based on the principle that the end cap 12 does not interfere with the internal components (such as the circuit board and the parts installed on the circuit board) of the electronic thermometer 10. This application is not limited to this, and the connection part 123 can also be designed based on other design principles.
[0053] In some embodiments, such as Figure 3 and Figure 6 As shown, the fixing part 121 faces the side cover 13 on the side ( Figure 6 The lower side of the fixing part 121 shown has a protrusion 124 surrounding the first hole H1, such as Figure 5 and Figure 6 As shown, the outer casing 11 is provided with a mounting hole H3 that matches the shape of the protrusion 124. When the end cap 12 is inserted into the inner casing 11, that is, after assembly, the protrusion 124 engages with the outer casing 11, for example, by engaging with the mounting hole H3 provided on the outer casing 11. Thus, the end cap 12 can be fixed to the outer casing 11.
[0054] In the above embodiments, such as Figure 3 and Figure 5 As shown, the front end L1 of protrusion 124 (i.e., the insertion end) Figure 3 The right side shown is arc-shaped, which facilitates the insertion of the end cap 12. The rear end L2 of the protrusion 124 (that is, the other end opposite to the insertion end, such as...) Figure 3 The left side shown is straight. After the end cap 12 is inserted into the housing 22, that is, after assembly, the rear end L2 of the protrusion 124 engages with the housing 11, for example, with the rear side of the mounting hole H3 provided on the housing 11. Figure 5 As shown on the left), this serves as a limit.
[0055] In some embodiments, such as Figure 3 and Figure 6 As shown, the end cap 12 has an extension direction along the housing 11 ( Figure 6 The guide portion 125, which extends in the left-right direction (as shown), guides the insertion of the end cap 12 along the inner wall of the housing 11 when the end cap 12 is inserted into the housing 11, that is, during assembly.
[0056] exist Figure 3 and Figure 6 In the example, the guide portion 125 is configured to form an opening along the circumference of the electronic thermometer 10. The position of this opening is used to house the aforementioned fixing portion 121 for fixing to the side cover 13. This application is not limited to this; the guide portion 125 may not be arranged along the aforementioned circumference, but may be arranged in a manner that extends from the end 122 of the end cover 12 in multiple ways, as long as it can be used to guide the insertion of the end cover 12.
[0057] In some embodiments, such as Figure 3 and Figure 6 As shown, the guide portion 125 has a claw portion 126 at its end. The claw portion 126 is used to limit and / or fix components inside the housing 11. For example, components of the electronic thermometer 10 inside the housing 11 can be fixed to the claw portion 126, or the claw portion 126 can limit the components of the electronic thermometer 10 inside the housing 11 to prevent them from moving out of their predetermined positions. The above is just an example. The claw portion 126 is provided to achieve further effects. Whether to provide it, how to provide it, and the number of claw portions, etc., depends on the number and arrangement of components inside the housing 11, as well as other requirements.
[0058] In some embodiments, such as Figure 3 and Figure 6 As shown, at least one corner of the end of the claw 126 is a beveled structure, that is, at least one corner of the end of the claw 126 is a chamfer C. This can further guide the end cap 12 when it is inserted into the housing 11, and prevent the end cap 12 from interfering with the components inside the housing 11 and getting stuck.
[0059] In some embodiments, such as Figure 3 As shown, the side of the guide portion 125 is also provided with a protrusion 127. When the end cap 12 is inserted into the housing 11, the protrusion 127 is embedded in the recess (not shown in the figure) provided on the inner wall of the housing 6, thereby playing a role in pre-fixing and limiting.
[0060] In some embodiments, such as Figure 3 and Figure 6 As shown, the end cap 122 has a groove 128 with a recessed groove, and a sealing ring is disposed in the groove 128. When the end cap 12 is inserted into the housing 11, the sealing ring abuts against the inner wall of the housing 11 and plays a sealing role.
[0061] In some embodiments, such as Figure 3 and Figure 6 As shown, a third hole H4 is provided on the side of the end 122 of the end cap 12. By providing the third hole H4, deformation of the electronic thermometer 10 after molding can be prevented, thus ensuring the yield rate. This application does not limit the location, depth, etc. of the third hole H4.
[0062] In this embodiment, the end cap 12 is integrally formed, and the material of the end cap 12 is not limited. This facilitates implementation and saves time and cost.
[0063] Figure 7 This is another schematic diagram of the side cover 13, showing the structure of the side cover 13 facing the interior of the housing 11.
[0064] In some embodiments, such as Figure 6 and Figure 7 As shown, a mounting part 131 for fixing to the outer casing 11 is provided on the side of the side cover 13 facing the inside of the outer casing 11. This application does not limit the fixing method. Figure 7 Taking the mounting part 131 as an example, which is a plate-shaped structure mounted on the outer shell 11.
[0065] In some embodiments, such as Figure 6 and Figure 7 As shown, a support portion 132 is also provided on the side of the side cover 13 facing the interior of the outer casing 11, which abuts against the components inside the outer casing 11. Figure 7 Taking the support portion 132 as an example, which is roughly rectangular, this application does not limit its shape. Figure 7 In the example, a full-circumference recessed area is also provided along the circumference of the support portion 132. A sealing ring can be installed in this recessed area, thereby playing a sealing role, preventing water and other foreign objects from entering the interior of the electronic thermometer 10, ensuring that the product performance is not affected, and improving the product life.
[0066] In some embodiments, such as Figure 6 and Figure 7 As shown, a rib 133 is also provided inside the support portion 132. The rib 133 can abut against the electronic components inside the housing 11, providing support and also increasing the strength of the side cover 13.
[0067] The above description only covers the structure of the electronic thermometer 10 relevant to this application. Other structures of the electronic thermometer 10, such as... Figure 1 The working principles of the button 15, display screen 14, and electronic thermometer 10 shown can be found in relevant technologies and will not be elaborated here.
[0068] According to the above embodiments, by designing a structure on the end cap 12 of the electronic thermometer 10 to fix the side cap 13, the number of parts is reduced, the assembly time is shortened, the assembly defect rate is reduced, and the cost is reduced compared to fixing the side cap 13 to a separate part inside the housing 11.
