DETAILED DESCRIPTION

[0056] To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0057] Hypertension disease is one of the most common internal diseases at present, and there are many patients with hypertension from the elderly population to the young population, so the distribution is very wide. The patients with hypertension need to closely observe their own physical conditions, and gradually treat the disease through diet and living habits.

[0058] In order to better monitor the fluctuation of blood pressure of patients, a sphygmomanometer emerges as the times require. The sphygmomanometer is an instrument for measuring blood pressure, also known as a blood pressure meter. The existing sphygmomanometer is divided into a mercury sphygmomanometer, an electronic sphygmomanometer and a spring table type sphygmomanometer. The spring table type sphygmomanometer and the electronic sphygmomanometer are more commonly used. The electronic sphygmomanometer is more intelligent and more humanized, and therefore is more popular with users.

[0059] The panel of the sphygmomanometer usually includes a perspective area for perspective display of the content of the display screen, and other areas of the panel are non-perspective areas. In the related art, the perspective area and the non-perspective area are usually formed by two parts of different materials, and the two parts are assembled to form the panel. Since the two parts use different materials, the cost and processing time are increased, and the production efficiency is low.

[0060] In addition, when the panel needs some other appearance effect, such as gilding process treatment on the outer annular edge of the panel, since the gilding area is annular, it is difficult to ensure the stability and reliability of the gilding process.

[0061] The embodiments of the present application will be described below in conjunction with Figures 1 to 12 The embodiments of the present application will be described below in conjunction with

[0062] According to the embodiments of the present application, on the one hand, a panel assembly is provided, which includes a cover body 1 and a transparent window 2. The transparent window 2 is injection molded and integrally formed with the cover body 1 by secondary injection molding.

[0063] In the embodiment, the transparent window 2 is injection molded and integrally formed with the cover body 1 by secondary injection molding, and the cover body 1 and the transparent window 2 are formed into an integral structure in the process of injection molding the cover body 1, so that the cost and processing time can be reduced, and the production efficiency can be improved.

[0064] Specifically, in the process of processing, the transparent window 2 is first injection molded, and then the transparent window 2 is placed into a molding mold for injection molding the cover body 1 to perform secondary injection molding, and the cover body 1 and the transparent window 2 are formed into an integral structure in the process of injection molding the cover body 1, so that the cost and processing time can be reduced, and the production efficiency can be improved.

[0065] It should be noted that the transparent window 2 is a perspective area, and the cover body 1 is a non-perspective area. The panel assembly is applied to a sphygmomanometer, and the content of the display screen can be observed through the transparent window 2.

[0066] Specifically, in one embodiment, the transparent window 2 is arranged at a middle position of the cover body 1.

[0067] In one embodiment, the transparent window 2 cooperates with the molding mold for injection molding the cover body 1 through a fool-proof structure. In this embodiment, the transparent window 2 and the molding mold for injection molding the cover body 1 have a specific cooperation position by setting the fool-proof structure, so that the position of the transparent window 2 can be effectively prevented from being placed incorrectly.

[0068] Specifically, when the transparent window 2 is placed in the molding mold for injection molding the cover body 1, the fool-proof structure is used to make the transparent window 2 have a specific placement position in the molding mold, so that the position of the transparent window 2 can be effectively prevented from being placed incorrectly. In one embodiment, the fool-proof structure comprises:

[0069] a protruding plate 204 arranged at one of the transparent window and the molding mold;

[0070] a recess arranged at the other one of the transparent window and the molding mold, and the protruding plate 204 is adapted to be embedded in the recess.

[0071] In this embodiment, the transparent window and the molding mold for injection molding the cover body have a specific cooperation position by cooperation of the protruding plate and the recess, so that the position of the transparent window can be effectively prevented from being placed incorrectly.

[0072] In one embodiment, the protruding plate 204 is provided with at least two protruding plates, and the protruding plates are asymmetrically arranged, and the recess and the protruding plate 204 are one-to-one correspondingly arranged.

[0073] In this embodiment, the protruding plates are asymmetrically arranged, so that the transparent window has a specific placement position in the molding mold for injection molding the cover body, and the position of the transparent window can be effectively prevented from being placed incorrectly.

[0074] In one embodiment, as shown inFigure 7 、 Figure 8 、 Figure 9 and Figure 10 The transparent window 2 comprises the protruding plate 204 at the first edge 201, the second edge 202 and the third edge 203 in sequence, the first edge 201, the second edge 202 and the third edge 203 are respectively provided with the protruding plate 204, and the protruding plate 204 at the first edge 201 is asymmetrically arranged with the protruding plate 204 at the third edge 203. In this embodiment, by asymmetrically arranging the protruding plate 204 at the first edge 201 with the protruding plate 204 at the third edge 203, in combination with the protruding plate 204 arranged at the second edge 202, the specific placement position of the transparent window 2 in the forming mold for injection molding the cover body 1 can be ensured, and the misplacement of the transparent window 2 can be effectively prevented.

[0075] Specifically, in an embodiment, the distance between the protruding plate 204 at the first edge 201 and the second edge 202 is not equal to the distance between the protruding plate 204 at the second edge 202 and the second edge 202, so as to realize the asymmetric arrangement of the protruding plate 204 at the first edge 201 with the protruding plate 204 at the third edge 203.

[0076] More specifically, in combination with Figure 10 The distance between the protruding plate 204 at the first edge 201 and the second edge 202 is less than the distance between the protruding plate 204 at the second edge 202 and the second edge 202, so as to realize the asymmetric arrangement of the protruding plate 204 at the first edge 201 with the protruding plate 204 at the third edge 203. Of course, in an alternative embodiment, the distance between the protruding plate 204 at the first edge 201 and the second edge 202 is greater than the distance between the protruding plate 204 at the second edge 202 and the second edge 202, so as to realize the asymmetric arrangement of the protruding plate 204 at the first edge 201 with the protruding plate 204 at the third edge 203.

[0077] More specifically, continuing to refer to Figure 10 The protruding plate 204 at the first edge 201 is located at the middle position of the first edge 201, and the protruding plate 204 at the third edge 203 is farther away from the second edge 202 relative to the middle position of the third edge 203.

[0078] More specifically, continuing to refer to Figure 10 The transparent window 2 is rectangular, and the first edge 201 and the third edge 203 are parallel to each other.

[0079] Further referring to the figures, the protruding plate 204 at the second edge 202 is not located at the middle of the second edge 202, in combination with the asymmetric arrangement of the protruding plate 204 at the first edge 201 with the protruding plate 204 at the third edge 203, the specific placement position of the transparent window 2 in the forming mold for injection molding the cover body 1 can be ensured, and the misplacement of the transparent window 2 can be effectively prevented.

[0080] In an embodiment not shown in the figures, the fool-proof structure can only include a protruding plate 204 arranged at one edge of the transparent window 2, and the protruding plate 204 is not located at the middle of the edge.

[0081] In an embodiment not shown in the figures, the fool-proof structure can include protruding plates 204 arranged at two adjacent edges of the transparent window 2, for example, the protruding plates 204 arranged at the first edge and the second edge respectively, the protruding plate 204 arranged at the first edge is located at the middle of the first edge, and the protruding plate 204 arranged at the second edge is deviated from the middle of the second edge.

[0082] In an embodiment not shown in the figures, the fool-proof structure can be fool-proof marks arranged at each edge of the transparent window 2, for example, numerical marks or character marks, which prompt the user to place the transparent window 2 at the correct position.

[0083] In an embodiment, the transparent window 2 is further provided with a first positioning structure adapted to cooperate with the forming mold to position. In this embodiment, the first positioning structure is arranged to position the transparent window 2 with the forming mold, so that the position of the transparent window 2 in the forming mold is fixed, preventing the position of the transparent window 2 from moving during the secondary injection molding process, and ensuring the processing efficiency.

[0084] Specifically, when the panel assembly is processed, the transparent window 2 is first injection molded, and then the transparent window 2 is placed into the forming mold for injection forming the cover body 1 through the fool-proof structure. The fool-proof structure can ensure that the placement position of the transparent window 2 is correct, and the position of the transparent window 2 is positioned through the first positioning structure, preventing the position of the transparent window 2 from moving. Then, the secondary injection molding is performed, and the cover body 1 and the transparent window 2 are formed as an integral structure during the injection molding of the cover body 1, so as to reduce the cost and processing time, and improve the production efficiency.

[0085] Of course, when the fool-proof structure can cooperate with the forming mold to play a positioning role, the first positioning structure can be unnecessary.

[0086] In one embodiment, the first positioning structure comprises a protruding column 205 arranged on the protruding plate 204, and the protruding column 205 is provided with a positioning hole 206. The positioning protruding column 205 is adapted to cooperate with a positioning column in a forming mold. In this embodiment, by arranging the protruding column 205 on the protruding plate 204 and arranging the positioning hole 206 in the protruding column 205, the positioning hole 206 can cooperate with the positioning column in the forming mold for injection molding of the cover body 1 on one hand, so as to position the transparent window 2 in the forming mold for injection molding of the cover body 1. On the other hand, the positioning hole 206 can reduce material, so as to prevent the transparent window 2 from being non-uniform in thickness. Meanwhile, the protruding column 205 is arranged on the protruding plate 204, so that the first positioning structure does not need to be additionally processed at other positions of the transparent window 2, and the structure of the transparent window 2 is beautiful and convenient for injection molding.

[0087] Specifically, in one embodiment, as shown in Figure 7 the protruding column 205 is a cylinder, and the positioning hole 206 is a circular hole.

[0088] It should be noted that the positioning hole 206 can be a through hole or a blind hole.

[0089] In one embodiment not shown in the figure, the first positioning structure can be a positioning column arranged on the protruding plate 204, and the positioning column cooperates with a positioning hole in a forming mold for injection molding of the cover body 1, so as to position the transparent window 2 in the forming mold for injection molding of the cover body 1.

[0090] In one embodiment, each corner of the transparent window 2 is provided with a first step 207, and the cover body 1 comprises a first protruding part 101 adapted to the first step 207. In this embodiment, by arranging the first step 207 at each corner of the transparent window 2, and arranging the first protruding part 101 adapted to the first step 207 in the cover body 1, the first protruding part 101 abuts against the first step 207, and after the secondary injection is completed, each corner of the transparent window 2 is wrapped by the cover body 1 and inlaid into the cover body 1, so as to improve the structural strength of the panel assembly.

[0091] Specifically, in one embodiment, as shown in Figure 10 the transparent window 2 is rectangular, so it has four corners, and each corner is provided with the first step 207. The cover body 1 comprises four first protruding parts 101 adapted to the first step 207, and the first protruding part 101 abuts against the first step 207. After the secondary injection is completed, the four corners of the transparent window 2 are wrapped by the cover body 1 and inlaid into the cover body 1, so as to improve the structural strength of the panel assembly.

[0092] In one embodiment, each corner of the transparent window 2 is arc-shaped.

[0093] In this embodiment, since each corner of the transparent window 2 is circular, the transparent window 2 is more convenient to place into the forming mold.

[0094] In an embodiment not shown in the drawings, each corner of the transparent window 2 is a right angle.

[0095] In an embodiment, as shown in Figure 6 , Figure 11 and Figure 12 , the outer edge of the transparent window 2 is provided with a second step 208, the cover body 1 is provided with a second protruding part 102 matched with the second step 208, and the corners of the transparent window 2 are clamped between the first protruding part 101 and the second protruding part 102. In this embodiment, by providing the second step 208 on the outer edge of the transparent window 2, and providing the second protruding part 102 matched with the second step 208 on the cover body 1, the contact area between the transparent window 2 and the cover body 1 can be increased, the adhesion effect of the two parts is greatly enhanced, and the overall strength of the panel assembly is improved. By clamping the corners of the transparent window 2 between the first protruding part 101 and the second protruding part 102, the transparent window 2 is completely embedded in the cover body 1, and the first step 207 part is completely wrapped, improving the structural strength of the panel assembly.

[0096] In an embodiment, the second step 208 is annular.

[0097] Specifically, as shown in Figure 6 , the first step 207 and the second step 208 are respectively located on the upper and lower sides of the transparent window 2, and the width of the first step 207 is smaller than the width of the second step 208, and the height of the first step 207 is also smaller than the height of the second step 208.

[0098] In an embodiment, the inner side of the cover body 1 is provided with a second positioning structure 103 for cooperating with the positioning of the gilding tool 3. In this embodiment, by providing the second positioning structure 103 on the inner side of the cover body 1 for cooperating with the positioning of the gilding tool 3, the entire panel assembly can be fixed on the gilding tool 3 through the second positioning structure 103, the gilding tool 3 rotates to drive the panel assembly to rotate as a whole, and the hot-pressing gilding head 4 contacts the outer edge of the cover body 1 to perform gilding processing. The second positioning structure 103 can realize stable and reliable gilding process.

[0099] It should be noted that the inner side of the cover body 1 is provided with the second positioning structure 103, and the gilding tool 3 needs to be provided with a positioning part matched with the second positioning structure 103, so as to stably fix the cover body 1 on the gilding tool 3.

[0100] In one embodiment, the second positioning structure 103 is a stepped structure with at least two layers. In this embodiment, the stepped structure 103 increases the contact area and stress zone with the hot stamping fixture 3, making the hot stamping process more stable and reliable. Simultaneously, the stepped structure 103 does not affect the appearance of the panel assembly, resulting in a more aesthetically pleasing appearance.

[0101] Specifically, when the second positioning structure 103 is a stepped structure with at least two layers, the positioning part of the hot stamping fixture 3 is also a stepped structure with at least two layers, so as to increase the contact area and stress area between the cover body 1 and the hot stamping fixture 3, making the hot stamping process more stable and reliable.

[0102] Specifically in one embodiment, such as Figure 6 As shown, the multi-layer stepped structure is specifically a three-layer stepped structure. Correspondingly, the positioning part of the hot stamping fixture 3 is also a three-layer stepped structure, which increases the contact area and stress area between the cover body 1 and the hot stamping fixture 3, making the hot stamping process more stable and reliable.

[0103] Of course, this embodiment does not limit the specific values ​​of the multi-layered stepped structure; they can be... Figure 6 The three-tiered staircase structure shown can also be a one-tiered, two-tiered, or four-tiered staircase structure.

[0104] In one embodiment not shown in the figure, the second positioning structure 103 may be a positioning post or a positioning hole. Correspondingly, the positioning part of the hot stamping fixture 3 is a positioning hole or a positioning post.

[0105] In one embodiment, an annular boss 104 is provided on the outer peripheral wall of the cover body 1. The outer peripheral wall of the annular boss 104 forms a hot stamping position, and the annular boss 104 can prevent accidental hot stamping of non-hot stamping surfaces during hot stamping. In this embodiment, by providing an annular boss 104 on the outer peripheral wall of the cover body 1, and the outer peripheral wall of the annular boss 104 forms a hot stamping position, when the hot press head 4 contacts the outer peripheral wall of the annular boss 104, it will not contact other areas. Therefore, the annular boss 104 can prevent accidental hot stamping of non-hot stamping surfaces during hot stamping, thereby improving the product qualification rate.

[0106] Specifically in one embodiment, such as Figure 6 As shown, the outer peripheral wall of the annular boss 104 is an arc surface, and the working surface of the hot press head 4 is also an arc surface. Since the annular boss 104 protrudes outward, the working surface of the hot press head 4 will not contact the non-hot stamping surface.

[0107] According to an embodiment of the present invention, in another aspect, a process for the above-described panel assembly is also provided, comprising the following steps:

[0108] A transparent viewing window 2 is manufactured by injection molding;

[0109] The transparent window 2 is placed into a forming mold for injection molding the cover body 1 for secondary injection molding.
