[0030] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0033] When engaging in outdoor activities, people sometimes need to wear helmets for personal protection, such as racing, cycling, and hiking. During these activities, users may need to use electronic devices such as mobile phones and cameras for navigation, photography, and other simultaneous operations. In these situations, when the electronic devices cannot be held in the hand, they can be mounted and secured to the helmet's windshield. This not only frees up the hands but also keeps the electronic devices in front of the user's field of vision for easy observation and use. Therefore, there is a need to develop a connection device that can stably fix electronic devices to the windshield or install them on the windshield of a bicycle.
[0034] Referring to Figure 1, this utility model provides a novel clamping device 1 for a curved windshield 2. Electronic devices are mounted on this clamping device 1. The clamping device 1 enhances its fit with the curved windshield 2 through an inner wall with concave and convex designs, thereby indirectly and stably clamping and mounting the electronic devices onto the curved windshield 2. It should be noted that the windshield on the helmet is curved, i.e., the curved windshield 2. The clamping device 1 of this application can stably clamp and mount electronic devices onto the helmet.
[0035] Specifically, referring to Figures 1 and 2, the clamping device 1 includes a first clamping plate 10 and a second clamping plate 20 arranged opposite to each other. The first clamping plate 10 and the second clamping plate 20 can be relatively close to each other to clamp the curved windshield 2, or the first clamping plate 10 and the second clamping plate 20 can be relatively far apart to release the curved windshield 2. The inner wall of the first clamping plate 10 facing the second clamping plate 20 is provided with an outer surface adaptation wall 11 for the curved windshield 2. It should be noted that the outer surface of the curved windshield 2 is convex, and the outer surface adaptation wall 11 is attached to the outer surface of the curved windshield 2, thus the outer surface adaptation wall 11 is concave. As shown in Figure 2, the middle region of the outer surface adaptation wall 11 is provided with a recessed portion 12, and the two side edges of the outer surface adaptation wall 11 are provided with transition portions 13 whose height increases relative to the recessed portion 12. The recessed portion 12 and the transition portion 13 are connected to form a contact path adapted to the curvature of the outer surface of the curved windshield 2 (as shown in Figure 1).
[0036] Referring to Figures 1 and 3, the inner wall of the second clamping plate 20 facing the first clamping plate 10 is provided with an inner surface adaptation wall 21 for the curved windshield 2. It should be noted that the inner surface of the curved windshield 2 is concave, and since the inner surface adaptation wall 21 is attached to the inner surface of the curved windshield 2, it is convex. As shown in Figure 3, the middle region of the inner surface adaptation wall 21 has a protrusion 22, and the two side edges of the inner surface adaptation wall 21 have extensions 23 that are lower in height than the protrusion 22. The protrusion 22 and the extensions 23 are connected to form a contact path that adapts to the curvature of the inner surface of the curved windshield 2 (as shown in Figure 1).
[0037] It should be noted that when the curved windshield 2 is clamped onto the clamping device 1, the recessed portion 12 and the transition portions 13 on both sides contact the outer surface of the curved windshield 2, forming a contact path that adapts to the curvature of the outer surface of the curved windshield 2. Similarly, the protruding portion 22 and the extension portions 23 on both sides contact the inner surface of the curved windshield 2, forming a contact path that adapts to the curvature of the inner surface of the curved windshield 2. Therefore, this solution utilizes three-point positioning and the stability principle of a triangle to enhance the stability of the curved windshield 2 when clamped onto the clamping device 1.
[0038] The clamping device 1 provided in this application has two inner sidewalls that are adapted to the curvature of the inner and outer surfaces of the curved windshield 2 to form a matching contact path, which greatly improves the fit between the clamping device 1 and the curved windshield 2, thereby improving the clamping stability of the clamping device 1 on the curved windshield 2. When users are engaged in outdoor activities and wearing helmets, electronic devices can be stably mounted on the curved windshield 2 of the helmet using the clamping device 1. This not only frees up the hands but also fixes the electronic devices in front of the user's field of vision for easy observation and use at any time.
[0039] Preferably, referring to Figures 2 and 3, in one embodiment, the outer surface adapter wall 11 and the inner surface adapter wall 21 are spaced apart and parallel to each other, that is, the curvature of the recessed portion 12 and the protrusion 22 are consistent, and the curvature of the transition portion 13 and the extension portion 23 are consistent. Optionally, in a specific embodiment, the recessed portion 12 and the transition portion 13 are smoothly connected to form an arc-shaped concave surface (not shown), and the protrusion 22 and the extension portion 23 are smoothly connected to form an arc-shaped convex surface (not shown). The arc-shaped concave surface and the arc-shaped convex surface are parallel to each other and their corresponding positions have equal curvature. It should be noted that the curved windshield 2 has a certain deformation capability, and its curvature can change slightly within a certain range. The arc-shaped concave surface can seamlessly fit with the outer surface of the curved windshield 2 with different curvatures, and the arc-shaped convex surface can seamlessly fit with the inner surface of the curved windshield 2 with different curvatures, so as to enhance the fit between the curved windshield 2 and the inner wall of the clamping device 1 and further improve the clamping stability. It should be noted that, in conjunction with Figures 2 and 3, in one embodiment, the recessed portion 12 and the transition portion 13 do not need to be smoothly connected, nor do the protruding portion 22 and the extension portion 23 need to be smoothly connected. It is only necessary to satisfy that the recessed portion 12 is lower than the transition portion and the protruding portion 22 is higher than the extension portion 23 to form a contact path that adapts to the curvature of the inner and outer surfaces of the curved windshield 2.
[0040] Preferably, referring to Figures 2 and 3, in one embodiment, the transition portion 13 is symmetrically arranged relative to the recessed portion 12, and the curvature of the two transition portions 13 is consistent; the extension portion 23 is symmetrically arranged relative to the protruding portion 22, and the curvature of the two extension portions 23 is consistent. This symmetrical structural design improves the aesthetics and harmony of the entire clamping device 1, and also ensures that the clamping force on the curved windshield 2 from the clamping device 1 is balanced from left to right, thus further enhancing the clamping stability. It should be noted that in this application, the clamping device 1 is not necessarily symmetrically arranged.
[0041] Optionally, referring to Figures 4-6, in one embodiment, the clamping device 1 includes an adjusting member 30, which includes a connected knob 31 and a locking shaft 32, with the knob 31 and locking shaft 32 circumferentially limiting each other. The knob 31 is exposed on the outer side wall of the first clamping plate 10 facing away from the second clamping plate 20. The locking shaft 32 passes through the first clamping plate 10 and is threadedly connected to the second clamping plate 20. The threaded connection enables synchronous rotation and movement. Therefore, rotating the knob 31 causes the first clamping plate 10 and the second clamping plate 20 to move closer or further apart, thereby clamping or releasing the curved windshield 2 (referring to Figure 1). In another embodiment, the adjusting member 30 can be connected in reverse, that is, the knob 31 can also be exposed on the outer side wall of the second clamping plate 20 facing away from the first clamping plate 10, and the locking shaft 32 passes through the second clamping plate 20 and is threaded to the first clamping plate 10. Rotating the knob 31 can move the first clamping plate 10 and the second clamping plate 20 closer or further apart, thereby clamping or releasing the curved windshield 2 (refer to Figure 1). Here, the locking shaft 32 and the outer surface adapter wall 11 need to be spaced apart, and the locking shaft 32 and the inner surface adapter wall 21 need to be spaced apart, so that the adjusting member 30 does not affect the clamping and installation of the curved windshield 2. It should be noted that in this application, any means that can adjust the first clamping plate 10 and the second clamping plate 20 to move closer or further apart should be protected. Whether the knob 31 and the locking shaft 32 are provided or not is not limited, and the position of the threaded connection of the locking shaft 32 is not limited. For example, in other embodiments, two connected clamping blocks that can be relatively close or far apart can be hung on the outer walls of the first clamping plate 10 and the second clamping plate 20 respectively, and the user can indirectly adjust the distance between the first clamping plate 10 and the second clamping plate 20 by adjusting the distance between the two clamping blocks.
[0042] Preferably, referring again to Figures 4 and 6, in one embodiment, the adjusting member 30 includes a telescopic spring 33. The telescopic spring 33 is disposed between the first clamping plate 10 and the second clamping plate 20 and is passed through by the locking shaft 32. The telescopic spring 33 accumulates or releases elastic force along the clamping direction (the direction from the first clamping plate 10 to the second clamping plate 20). The elastic force released by the telescopic spring 33 can provide a buffering force, has a shock absorption function, and prevents the curved windshield 2 from shaking, so as to maintain the stability of the electronic equipment. It should be noted that the inclusion or exclusion of the telescopic spring 33 is not limited if buffering and shock absorption are not considered.
[0043] Preferably, referring to Figures 4, 5, and 7, in one embodiment, the clamping device 1 includes a connecting post 40 parallel to the locking shaft 32. One end of the connecting post 40 is fixedly connected to the first clamping plate 10, and the other end is movably connected to the second clamping plate 20, providing space for the first clamping plate 10 and the second clamping plate 20 to move closer or further apart. Similarly, in another embodiment, as shown in Figure 7, the connecting post 40 can be connected in reverse, that is, one end of the connecting post 40 is fixedly connected to the second clamping plate 20, and the other end is movably connected to the first clamping plate 10, also providing space for the first clamping plate 10 and the second clamping plate 20 to move closer or further apart. Here, the connecting post 40 and the outer surface adapter wall 11 need to be spaced apart, and the connecting post 40 and the inner surface adapter wall 21 need to be spaced apart, so that the adjusting member 30 does not affect the clamping and installation of the curved windshield 2. Optionally, as shown in Figure 7, the number of connecting posts 40 can be multiple (two) and symmetrically arranged relative to the locking shaft 32. It should be noted that the connecting post 40 is provided to improve the connection stability between the first clamping plate 10 and the second clamping plate 20. In other embodiments of this application, the presence or absence of the connecting post 40 is not limited, and the number of connecting posts 40 is not limited.
[0044] Optionally, referring to Figures 6-8, in one embodiment, the outer wall of the first clamping plate 10 facing away from the second clamping plate 20, or the outer wall of the second clamping plate 20 facing away from the first clamping plate 10, is provided with a fixing part 50 for mounting electronic equipment. Figure 8 illustrates that the fixing part 50 includes a cold shoe groove 51 and a threaded interface 52. The cold shoe groove 51 is located on the outer wall of the second clamping plate 20 and is used for sliding external electronic equipment; the threaded interface 52 is located on the outer side of the first clamping plate 10 and is used for threaded external electronic equipment. It should be noted that in this application, the presence or absence of the cold shoe groove 51 or the threaded interface 52, as well as their location, are not limited. Any means or methods that enable external electronic equipment connection should be included, that is, the fixing part 50 can also be an external connection method such as a dovetail structure, a quick-release plate, or a locking shaft.
[0045] Preferably, referring to Figures 4 and 6, in one embodiment, the clamping device 1 includes a first flexible pad 61 and a second flexible pad 62. The first flexible pad 61 is attached to the inner wall of the first clamping plate 10, and an outer surface adapter wall 11 is formed on the side of the first flexible pad 61 opposite to the first clamping plate 10. The second flexible pad 62 is attached to the inner wall of the second clamping plate 20, and an inner surface adapter wall 21 is formed on the side of the second flexible pad 62 opposite to the second clamping plate 20. On the one hand, the flexible pad (first flexible pad 612 or second flexible pad 62) has an anti-slip function to further enhance the clamping and installation stability of the curved windshield 2; on the other hand, the flexible pad has a certain deformation capacity. Tightening the knob 31 reduces the distance between the first clamping plate 10 and the second clamping plate 20, increases the clamping force, and the flexible layer is deformed under compression to further adapt to the curvature of the inner and outer surfaces of the curved windshield 2, increasing the contact area between the flexible pad and the curved windshield 2, thereby further enhancing the clamping and installation stability of the curved windshield 2. It should be noted that, without considering the stability of the clamping and installation of the further curved windshield 2, the setting of the flexible pad is not limited, that is, the setting of the first flexible pad 61 or the second flexible pad 62 is not limited.
[0046] In one embodiment, referring to Figures 2 and 3, the curvature of the first flexible pad 61 corresponding to the recess 12 is equal to the curvature of the second flexible pad 62 corresponding to the protrusion 22; the curvature of the first flexible pad 61 corresponding to the transition portion 13 is equal to the curvature of the second flexible pad 62 corresponding to the extension portion 23. That is, the inner sidewalls of the first flexible pad 61 and the second flexible pad 62 are spaced apart and parallel to each other. Here, the inner sidewalls of the first clamping plate 10 and the second clamping plate 20 do not need to be directly processed into concave and convex states. The inner and outer surface curvatures of the curved windshield 2 can be adapted by attaching flexible pads with concave and convex designs, thereby greatly reducing the processing cost and processing difficulty of the entire clamping device 1. Furthermore, the flexible pads are detachably attached to the inner sides of the first clamping plate 10 and the second clamping plate 20. After the clamping device 1 is detached from the flexible pads, it can be used for clamping functions, making the entire clamping device 1 multifunctional and increasing its practicality. It should be noted that the curvature of the corresponding positions on the inner sides of the first flexible pad 61 and the second flexible pad 62 does not necessarily have to be equal; it is only necessary to be able to clamp and install the adapted curved windshield 2.
[0047] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
