[0041] Please refer to Figures 1 to 8 The present invention provides a display module 1000, comprising a watch base 1 and a display module 2. The display module 2 is provided with a display screen 21 for displaying various types of information. The display screen 21 can also be configured as a practical screen such as a touch screen. One of the watch base 1 and the display module 2 is provided with a connecting portion 3, and the other is provided with a mating portion 4. The connecting portion 3 includes a rotatable hook 31 and a pressing portion 5 that movably abuts against the hook 31. The hook 31 can be engaged or disengaged with the mating portion 4. The mating portion 4 includes a buckle 41 and a first plug-in portion 42. The watch base 1 has the buckle 41 at one end and the first plug-in portion 42 at the other end. The connecting portion 3 includes the hook 31 and a second plug-in portion 32. The display module 2 has the hook 31 at one end and the second plug-in portion 32 at the other end. The buckle 41 and the hook 31 are plugged together, and the first plug-in portion 42 and the second plug-in portion 32 are plugged together, so that the display module 2 can be detachably mounted on the watch base 1.

[0042] In the technical solution of the present invention, the table base 1 and the display module 2 of the display module 1000 are detachable. By providing a connecting part 3 on one of the display module 2 and the table base 1, and providing a matching part 4 for matching with the connecting part 3 on the other one, the display module 2 is assembled to the table base 1. At this time, the hook 31 on the connecting part 3 is engaged with the matching part 4. If the display module 2 is to be removed, the pressing part 5 is pressed to disengage the hook 31 from the matching part 4, thereby realizing the removal or replacement of the display module 2 separately. Moreover, the user only needs to press the pressing part 5 to complete the disassembly of the display module 2 and the table base 1, without the aid of professional tools. This further simplifies the installation of the display module 2 on the table base 1, greatly improving the convenience of disassembly and assembly of the display module 2.

[0043] To ensure that the display module 2 can be reliably matched with the watch base 1 when it is installed, and that they do not disengage in the non-disassembly state, the matching portion 4 includes a buckle 41 and a first plug-in portion 42. The buckle 41 is provided on the watch base 1 and is located at a relative position to the hook 31, and the hook 31 is provided on the display module 2. It should be noted that when the buckle 41 and the hook 31 are swapped, that is, a rotatable hook 31 is provided on the watch base 1, and a buckle 41 that cooperates with it is provided on the display module 2, the display module 2 and the watch base 1 can still be quickly disassembled and assembled. At this time, the pressing portion 5 used to abut against the rotatable hook 31 and drive the hook 31 is adaptively adjusted to the watch base 1. Furthermore, in one embodiment of the present invention, the mating portion 4 and the connecting portion 3 respectively include a buckle 41, a first plug-in portion 42, a hook 31, and a second plug-in portion 32, and the buckle 41 and the hook 31 are respectively located at the same end of the dial and the display module 2, and the first plug-in portion 42 and the second plug-in portion 32 are respectively located at the same end on the other side of the dial and the display module 2. Therefore, the display module 2 in this case can also be pre-positioned by plugging the second plug-in portion 32 at one end with the first plug-in portion 42 on the watch holder 1, and then the hook 31 on the display module 2 is snap-fitted with the buckle 41 on the watch holder 1 to complete the installation of the display module 2. At this time, the pre-fixation of the plug-in in this process can realize the pre-alignment of the display module 2 on the watch holder 1 to facilitate subsequent further installation, and the subsequent snap-fitting itself is also relatively simple, which is conducive to simplifying the installation of the display module on the carrier 12 to improve the convenience of disassembly and assembly of the display module.

[0044] In one embodiment of the present invention, in order to further assist the pre-positioning of the display module 2 and the meter base 1 during installation, the meter base 1 is provided with a bearing member 12. For details, please refer to Figure 2The carrier 12 is integrally formed with the main body of the watch stand 1 and is located at the bottom of the receiving groove 11, spaced below the first plugging portion 42. When the display module 2 is inserted obliquely into the receiving groove 11, the carrier 12 abuts against the lower wall of the display module 2, ensuring precise insertion of the first plugging portion 42 and the second plugging portion 32. After one end of the display module 2 is pre-aligned with the watch stand 1, to facilitate insertion of the display module 2 into the receiving groove 11 of the watch stand 1, the sidewalls of the receiving groove 11 gradually decrease in cross-sectional area from the notch to the bottom of the groove. This creates a bowl-shaped structure with a larger top and smaller bottom. This reduces the alignment requirements for the display module 2 when installed within the receiving groove 11, while also facilitating the engagement between the hook 31 on the display module 2 and the latch 41 on the watch stand 1. Furthermore, the bowl-shaped structure provides additional stability, making it less likely to loosen or shift once the display module 2 is properly installed, ensuring its stability and reliability. In addition, this design also helps to protect the display module 2, especially when it is subjected to shock or vibration, the bowl-shaped structure can provide a certain degree of buffering.

[0045] It should be noted that the first plug-in portion 42 provided on the display module 2 and the second plug-in portion 32 provided on the meter holder 1 can adopt the cooperation of a snap-in protrusion and a snap-in groove, or can adopt the cooperation of a magnetic part and a magnetic conductive part. The present invention does not limit this. In one embodiment of the present invention, one of the first plug-in portion 42 and the second plug-in portion 32 is a snap-in protrusion 421, and the other is a snap-in groove 321. When the snap-in protrusion 421 is provided on the display module 2, the meter holder 1 is provided with a snap-in groove 321 relatively; when the snap-in groove 321 is provided on the display module 2, the meter holder 1 is provided with a snap-in groove 321 relatively. Considering that the snap-in protrusion 421 and the snap-in groove 321 form a certain angle when plugged in, in order to facilitate the snap-in connection between the two, the lower edge of the snap-in protrusion 421 is chamfered to eliminate the right angle, thereby avoiding the right angle abutting against the notch of the snap-in groove 321 and making it difficult to assemble.

[0046] To install the hook 31, the display module 2 is provided with a first mounting groove 22, and a first through-hole 221 is provided at the bottom of the first mounting groove 22. The hook 31 is provided in the first mounting groove 22 and extends from the first through-hole 221 to engage with the latch 41 below the first through-hole 221. In a further embodiment, to ensure structural reliability, the display module 2 is provided with two linked hooks 31, which are respectively engaged and fixed with the two latches 41 on the watch base 1. This design can reduce the force exerted on the individual hooks 31 and latches 41, so that the latching and retaining force is evenly distributed between the two groups of hooks 31 and latches 41. Since the hook 31 is disengaged by rotation in this embodiment, a certain amount of space for movement is required. In view of this, the side of the hook 31 facing away from the latch 41 forms a downwardly inclined surface, which forms a certain angle with the inner wall of the first mounting groove 22, thereby facilitating the upward rotation of the hook 31 within the first mounting groove 22.

[0047] In this embodiment, the table base 1 is further formed with a first avoidance groove 13, which is arranged close to the buckle 41. For details, please refer to Figure 2 The design of the first avoidance groove 13 allows the hook 31 to pass smoothly during the insertion and engagement process, avoiding interference caused by direct contact, reducing resistance during assembly and potential damage to the buckle 41. This structure not only ensures a smooth engagement, but also helps protect the integrity of the buckle 41 and extend its service life. Furthermore, the presence of the avoidance groove helps improve the accuracy of the engagement, ensuring that the hook 31 and buckle 41 are accurately positioned and locked, thereby providing a more stable and secure connection. The avoidance groove design optimizes the overall performance of the engagement structure, making the engagement and disengagement processes more efficient and reliable.

[0048] This solution is to realize the rotation release by pressing. The display module 2 is provided with a second mounting groove 23. The bottom of the second mounting groove 23 is provided with a second through hole 231 communicating with the first mounting groove 22. For details, please refer to Figure 2 and Figure 4 The pressing portion 5 is movably provided in the second mounting groove 23 and extends into the abutting portion 51 toward the first mounting groove 22 through the second through hole 231. By pressing the pressing portion 5, the pressing portion 5 transmits the pressure as the movement of the abutting portion 51, causing the abutting portion 51 to move toward the side of the hook 31, thereby supporting the hook 31 and causing it to rotate around the rotating axis, thereby achieving rotational disengagement. It should be noted that the abutting portion 51 and the pressing portion 5 are an integrated structure, such as by injection molding or by CNC machine tool processing, and can be adaptively adjusted according to actual needs and the material of the product. The integrated molding process can ensure the stability and integrity of the pressing portion 5 structure, improve manufacturing efficiency and reduce costs. This design also makes the button more precise and durable during installation, while providing a better appearance texture and user experience.

[0049] The pressing portion 5 has a first position and a second position. For details, please refer to Figure 7 and Figure 8 , Figure 7 The pressing portion 5 is shown in the second position. Figure 8The figure shows that the pressing part 5 is in the first position. When the pressing part 5 is in the first position, the abutting part 51 abuts against the hook 31, and the hook 31 is engaged with the buckle 41; when the pressing part 5 is in the second position, the abutting part 51 and the hook 31 are still abutted, and the hook 31 is disengaged from the buckle 41. Therefore, the process of the user pressing the pressing part 5 is also the process of the pressing part 5 switching from the first position to the second position. In order to realize the reset of the pressing part 5, an elastic member 52 is sleeved on the abutting part 51, and the two ends of the elastic member 52 The ends of the hook 31 abut against the pressing portion 5 and the bottom wall of the second mounting groove 23 respectively. When the pressing portion 5 is in the second position, the elastic member 52 is compressed. When the user releases his hand, the elastic potential energy of the elastic member 52 is converted into kinetic energy of the pressing portion 5, thereby resetting the pressing portion 5 to the first position. At the same time, the hook 31 returns to its original position. When the display module 2 and the watch base 1 are assembled again, the lower guide surface of the hook 31 abuts against the upper guide surface of the buckle 41 to guide the hook 31 to rotate so that the hook 31 and the buckle 41 are re-engaged. In order to fix the pressing part 5, the abutting part 51 is provided with an annular groove 511. Correspondingly, a fixing ring 53 is provided inside the display module 2. The fixing ring 53 is sleeved on the annular groove 511. The outer diameter of the fixing ring 53 is larger than the inner diameter of the second through hole 231. In this way, the pressing part 5 can be limited. Furthermore, in order to realize the detachability of the pressing part 5, the fixing ring 53 is provided with a notch and an inner convexity 531. The inner convexity 531 is abutted with the abutting part 51 to achieve limitation. The fixing ring 53 can be deformed at the notch and detached from the abutting part 51, so that the pressing part 5 can be disassembled.

[0050] In order to facilitate the removal of the hook 31, the display module 2 is further provided with a mounting seat 6. For details, please refer to Figure 3 and Figure 5 , the mounting seat 6 is detachably arranged on the first mounting groove 22. It should be noted that the mounting seat 6 can be installed by screwing or fixed by clamping. The present invention does not limit this. In one embodiment of the present invention, the mounting seat 6 is fixed to the two screw holes of the notch of the first mounting groove 22 by bolts, and the hook 31 is installed on the shaft hole 62 of the mounting seat 6 through a rotating shaft. The mounting seat 6 is provided with a mounting notch 61, and the hook 31 is accommodated in the mounting notch 61. When the hook 31 needs to be disassembled, the mounting seat 6 is removed first, and the hook 31 rotatably installed on the mounting seat 6 can be conveniently disassembled and assembled.

[0051] In this embodiment, in order to realize the reset of the hook 31, a reset member 312 is provided on the side of the hook 31 facing away from the abutting portion 51. For details, please refer to Figure 3The back side of the hook 31 is provided with a receiving hole 311, which is a blind hole. Two receiving holes 311 are provided to respectively accommodate two reset members 312. The reset member 312 is preferably a spring. When the hook 31 is engaged with the buckle 41, the spring is in an extended state; when the hook 31 is disengaged from the buckle 41, the spring is in a compressed state. When the user releases the pressing part 5, the spring quickly pops open to reset the hook 31.

[0052] In one embodiment of the present application, the bottom of the receiving groove 11 is hollowed out. For details, please refer to Figure 2 and Figure 3 In this way, the lower bottom wall of the display module 2 can fit the user's wrist when the user wears it.
