Abstract
Description
Technical Field
[0001] This utility model belongs to the field of smartwatch technology, specifically relating to a watch pressure-maintaining device. Background Technology
[0002] In the component assembly process of products such as smartwatches and smart bracelets, pressure holding is required after the heart rate monitoring module and the middle frame are installed on the watch back and back. However, because the heart rate monitoring module and the middle frame are installed in different positions, pressure holding needs to be performed separately. Currently, a snap-fit pressure holding box is usually used for pressure holding, but this type of pressure holding box cannot control the pressure intensity in segments at the same time. It is necessary to perform pressure holding on the heart rate monitoring module and the watch back and the middle frame and the watch back twice, which doubles the pressure holding time and increases production costs. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings and deficiencies in the existing technology and provide a watch pressure-holding device that realizes segmented pressure holding of the watch's functional modules and the middle frame on the watch case. It can perform pressure holding simultaneously, improve pressure holding efficiency, and save processing time.
[0004] This utility model is achieved through the following technical solution:
[0005] A watch pressure-holding device includes an upper pressure mold, a lower support mold, a bottom case pressure-holding movable block, a first spring assembly, a modular pressure-holding movable block, and a second spring assembly. The upper pressure mold and the lower support mold are detachably connected along a first direction and enclosed to form a closed mold. The upper pressure mold has a coaxially arranged modular receiving groove and a bottom case receiving groove sequentially formed along a direction close to the lower support mold. The modular receiving groove and the bottom case receiving groove extend along the first direction. The modular receiving groove and the bottom case receiving groove are connected, and the inner diameter of the modular receiving groove is smaller than the inner diameter of the bottom case receiving groove. The bottom case pressure-holding movable block is movably accommodated within the bottom case receiving groove. The first spring assembly is arranged along a first direction, with one end connected to the bottom shell pressure-holding movable block and the other end connected to the bottom wall of the bottom shell receiving groove. The module pressure-holding movable block is movably accommodated within the module receiving groove along the first direction. The bottom shell pressure-holding movable block has a first receiving groove that corresponds to the position of the module receiving groove and is coaxially arranged, and the module pressure-holding movable block is movably inserted through the first receiving groove and the module receiving groove. The second spring assembly is arranged along the first direction, with one end connected to the module pressure-holding movable block and the other end connected to the bottom wall of the module receiving groove.
[0006] In the watch pressure-holding device provided by this utility model, the upper pressure mold and the lower support mold are detachably connected along a first direction and enclosed to form a closed mold, thereby forming an accommodating space for accommodating a smartwatch; the upper pressure mold has a module accommodating groove and a bottom case accommodating groove arranged coaxially, which are used to accommodate the functional modules on the watch and the watch bottom case, respectively; the bottom case pressure-holding movable block can be movably accommodated in the bottom case accommodating groove along the first direction. After the watch bottom case and the middle frame are installed, they can be placed on the lower support mold. When the pressure mold and the lower support mold enclose to form a closed mold, the bottom case pressure-holding movable block and the first spring assembly are squeezed, so that the watch bottom case and the middle frame at the edge of the watch bottom case located between the bottom case pressure-holding movable block and the lower support mold are squeezed. The first spring assembly can provide pressure-holding pressure to the watch bottom case and the middle frame at the edge of the watch bottom case according to the pressure received, thereby realizing pressure holding of the watch bottom case and the middle frame, and can provide different pressures according to the different weights of the watch bottom case and the middle frame; the module pressure-holding movable block can be movably accommodated in the module accommodating groove along the first direction. After the watch case and functional module are installed in the groove, the watch case can be placed on the lower mold. Since the functional module is small, it is located between the module pressure holding block and the lower mold. As the mold and the lower mold close to form a closed mold, the bottom case pressure holding block is squeezed. The module pressure holding block, the functional module, and the second spring group are also squeezed. The second spring group can provide pressure holding pressure to the watch case and the module on the watch case according to the pressure received, thus achieving pressure holding for the watch case and the functional module. Since the functional module and the middle frame are located at different installation positions on the watch case, the required pressure holding pressure for the two installation positions is different. The first spring group and the second spring group are connected to the bottom case pressure holding block and the module pressure holding block respectively, so as to apply pressure at different installation positions on the watch case at the same time. This achieves segmented pressure holding for the watch case and the middle frame, and the watch case and the functional module, so that the pressure holding pressure at the two installation positions can be adjusted to meet the pressure holding pressure requirements of the two installation positions. The watch pressure-holding device of this utility model realizes segmented pressure holding of the watch's functional modules and the middle frame on the watch case, and can perform pressure holding simultaneously, thereby improving pressure holding efficiency and saving processing time.
[0007] Furthermore, the first spring assembly includes a plurality of first spring elements, which are symmetrically distributed around the center of the bottom shell pressure-holding movable block. The symmetrical distribution of the first spring elements helps to ensure that the bottom shell pressure-holding movable block is subjected to uniform force and provides the same pressure to the bottom shell pressure-holding movable block, so that the pressure-holding pressure is the same at all points on the bottom shell and the middle frame.
[0008] Furthermore, the second spring assembly includes a plurality of second spring members, which are symmetrically distributed around the center of the module pressure-holding movable block. The symmetrical distribution of the second spring members helps to ensure uniform force distribution on the module pressure-holding movable block and provides the same pressure, thus ensuring that the pressure-holding pressure is the same at all points on the functional module.
[0009] Furthermore, an annular middle frame limiting block is provided on the side of the lower mold facing the upper mold, and the position of the annular middle frame limiting block corresponds to the position of the bottom shell pressure-holding movable block. The annular middle frame limiting block protrudes from the side of the lower mold facing the upper mold, allowing the smartwatch to be placed on the lower mold. At this time, the annular middle frame limiting block abuts against the middle frame of the smartwatch. When the upper mold and the lower mold close to form a closed mold, the annular middle frame limiting block can limit the middle frame of the smartwatch, preventing displacement of the smartwatch during the pressure-holding process.
[0010] Furthermore, the bottom shell pressure-holding movable block has a bottom shell conforming mold on the side facing the lower mold; the bottom shell conforming mold has a second receiving groove corresponding to the first receiving groove, so that the module pressure-holding movable block can be movably inserted into the first receiving groove and the second receiving groove. The smart watch can be placed on the lower mold. When the upper mold and the lower mold are closed to form a mold, one side of the smart watch bottom shell abuts against the lower mold, and the other side abuts against the bottom shell conforming mold, so that the upper mold and the lower mold squeeze the watch bottom shell when they are closed; at this time, the smart watch's functional module abuts against the pressure-holding movable block, and can pass through the second receiving groove and enter the first receiving groove to contact the module pressure-holding movable block as the lower mold squeezes, so that the functional module is fully squeezed.
[0011] Furthermore, the module pressure-holding movable block has a module conforming mold on the side facing the lower support mold. The smartwatch can be placed on the lower support mold, and when the upper pressure mold and the lower support mold are closed to form a mold, the functional module can abut against the module conforming mold to achieve sufficient pressure holding.
[0012] Furthermore, the edge of the upper mold is provided with a first snap-fit structure, and the edge of the lower mold is provided with a second snap-fit structure corresponding to the position of the first snap-fit structure. The first snap-fit and the second snap-fit structure are engaged and connected. The engagement and connection between the upper mold and the lower mold through the first snap-fit structure and the second snap-fit structure realizes the connection between them, so as to form a mold closing mechanism and provide pressure holding pressure.
[0013] Furthermore, the upper mold facing the lower mold has a first positioning structure, and the lower mold facing the upper mold has a second positioning structure corresponding to the position of the first positioning structure. The first positioning structure and the second positioning structure are engaged and connected. Precise alignment is achieved through the cooperation of the first and second positioning structures, ensuring accurate connection between the upper and lower molds and maintaining pressure in the correct position for the smartwatch.

Figure 2-3 and Figure 7-8 The first spring assembly 7 is arranged along the first direction. One end of the first spring assembly 7 is connected to the bottom shell pressure-holding movable block 3, and the other end is connected to the bottom wall of the bottom shell receiving groove 12.
[0035] The bottom shell pressure-holding movable block 3 has a first receiving groove 31 that corresponds to the position of the module receiving groove 11 and is coaxially arranged.

[0037] In the watch pressure-maintaining device provided in this embodiment, please refer to... Figure 2 The upper mold 1 and the lower mold 2 are detachably connected along a first direction and enclosed to form a mold, thereby creating an accommodating space for the smartwatch 10; please refer to Figure 3 The upper mold 1 has a coaxially arranged module receiving groove 11 and a bottom shell receiving groove 12, which are used to receive the functional module 103 and the watch bottom shell 101 on the smartwatch 10, respectively; please refer to Figure 1-6The bottom case pressure-holding movable block 3 can be movably accommodated in the bottom case receiving groove 12 along the first direction. After the watch bottom case 101 and the middle frame 102 are installed, they can be placed on the lower support mold 2. When the mold and the lower support mold 2 are closed to form a mold, the bottom case pressure-holding movable block 3 and the first spring group 7 are squeezed, so that the watch bottom case 101 and the middle frame 102 at the edge of the watch bottom case 101 located between the bottom case pressure-holding movable block 3 and the lower support mold 2 are squeezed. The first spring group 7 can reverse the pressure on the watch bottom case 101 and the middle frame 102 at the edge of the watch bottom case 101 according to the pressure received. The middle frame 102 at the edge of the watch case 101 provides pressure holding, thereby achieving pressure holding between the watch case 101 and the middle frame 102, and can provide different pressures according to the different weights of the watch case 101 and the middle frame 102; the module pressure holding movable block 5 can be movably accommodated in the module accommodating groove 11 along the first direction. After the watch case 101 and the functional module 103 are installed, the watch case 101 can be placed on the lower support mold 2. Since the functional module 103 is small in size, at this time the functional module 103... Located between the module pressure-holding movable block 5 and the lower bearing mold 2, when the pressure mold and the lower bearing mold 2 are closed to form a mold, the bottom case pressure-holding movable block 3 is squeezed. The module pressure-holding movable block 5, the functional module 103, and the second spring group 8 are also squeezed. The second spring group 8 can provide pressure-holding pressure to the watch bottom case 101 and the functional module 103 located on the watch bottom case 101 according to the pressure received, so as to achieve pressure holding of the watch bottom case 101 and the functional module 103. Since the functional module 103 and the middle frame 102 are located at different installation positions of the watch bottom case 101, the required pressure holding pressure of the two installation positions is different. The first spring group 7 and the second spring group 8 are connected to the bottom case pressure-holding movable block 3 and the module pressure-holding movable block 5 respectively, so as to apply pressure at different installation positions of the watch bottom case 101 at the same time. This realizes segmented pressure holding of the watch bottom case 101 and the middle frame 102, and the watch bottom case 101 and the functional module 103. The pressure holding pressure of the two installation positions is adjusted to meet the pressure holding pressure requirements of the two installation positions.

Simultaneous pressure holding is possible, improving pressure holding efficiency and saving processing time. In this embodiment, the case pressure-holding movable block 3 and the module pressure-holding movable block 4 are located between the upper mold 1 and the lower mold 2, and on the lower surface of the upper mold. The case pressure-holding movable block 3 and the module pressure-holding movable block 4 are connected to the upper mold 1 via a first spring group 7 and a second spring group 8, respectively.
