[0033] Considering that the soldering feet of the existing heating joints of heatable glass are large in area, the welding area is also large, and the time for melting the solder is long, which can easily destroy the stress balance of the glass plate at the welding position, reduce the strength of the glass plate at the welding position, or easily cause the glass plate to crack. The present application provides a heating joint 1 and a heatable glass assembly, which can maintain the stress balance of the glass plate at the welding position, thereby improving the strength of the glass plate at the welding position, reducing the risk of glass plate cracking, and facilitating application and promotion.

[0034] For details, please refer to the attached Figure 1 One embodiment of the present application provides a heating joint 1, which may include a welding foot 10 and a connecting structure 20. The welding foot 10 includes at least two branch structures 11, and the branch structures 11 on the welding foot 10 are symmetrically arranged about the axis 10a. The connection point between the connecting structure 20 and the welding foot 10 is located in the extension direction of the axis 10a, and the branch structures 11 located on the same side of the axis 10a are spaced to form a heat dissipation gap 10b.

[0035] The above-mentioned heating joint 1 is firstly configured into a plurality of branch structures 11 through the welding foot 10, so that the actual contact area between the welding foot 10 and the glass plate during welding can be directly reduced, and then the heat required for welding is reduced, so that the heat transferred from the welding foot 10 to the glass plate is reduced, and then the temperature difference change on the surface of the glass plate is reduced, so that the local stress change fluctuation of the glass plate at the welding position is reduced, the structural stability of the glass plate at the welding position is improved, and the risk of the glass plate cracking is reduced; at the same time, a heat dissipation gap 10b is provided between each branch structure 11, which helps to improve the heat dissipation effect during welding, reduces heat accumulation, and then can further reduce the temperature difference change on the surface of the glass plate, and improve the structural stability of the glass plate; in addition, the branch structures 11 on the welding foot 10 are symmetrically arranged about the axis 10a, so that heat can be transferred more evenly through the welding foot 10, and then during welding, the change fluctuation of the pull-off force value and the shear force value between the welding foot 10 and the glass can be reduced, thereby improving the welding effect.

[0036] Optionally, the heating joint 1 may further include a cable (not shown) and an electrical connection structure (not shown). One end of the cable is electrically connected to the welding foot 10 via the connection structure 20, and the electrical connection structure is disposed at the other end of the cable. The electrical connection structure is used for an external power source, thereby realizing the power input of the heating joint 1.

[0037] Optionally, the solder foot 10 may be provided with solder on its first surface, and the first surface is used to adhere to the glass plate during welding; in other words, the first surface is a side surface that contacts the glass plate for welding. In this way, when the solder foot 10 is heated, the solder on the first surface can be directly heated and melted, thereby improving the welding efficiency.

[0038] Optionally, in some other embodiments, the aforementioned solder can also be provided when welding is required. Specifically, the aforementioned solder can be applied to the position on the surface of the glass plate where welding is required, or applied to the first surface of the welding foot 10, or applied to the position on the surface of the glass plate where welding is required and the first surface of the welding foot 10 at the same time.

[0039] Optionally, the solder may be, but is not limited to, tin solder.

[0040] Optionally, combined Figure 5 As shown, the branch structure 11 has a width t, the width of the heat dissipation gap 10b is w, and the value range of w / t can be 0.2-4, so that the space size of the heat dissipation gap 10b can be increased while taking into account the branch structure 11 to maintain a sufficient welding area, and then the welding firmness and the stress effect on the glass plate can be taken into account, thereby improving the welding effect. For example, the value of w / t can be 0.2, 1, 1.8, 3.6 or 4.

[0041] Specifically, the arrangement of the branch structures 11 and the width of each branch structure 11 can be adjusted according to actual design requirements. It is only necessary to satisfy that the aforementioned multiple branch structures 11 are symmetrically distributed about the axis 10a and that the value range of w / t is 0.2-4. In other words, the widths of the branch structures 11 may be inconsistent.

[0042] More specifically, combined with Figures 1 to 4 As shown, Figures 1 to 4 Four embodiments of the heating joint of the present application having branch structures with different arrangements are shown respectively. The above four embodiments all meet the conditions that the multiple branch structures 11 are symmetrically distributed about the axis 10a, and the value range of w / t is 0.2-4. It can be understood that the present application also includes other embodiments of the heating joint with branch structures with different arrangements, which will not be repeated here.

[0043] Optionally, according to the above embodiments of the present application, the width t of the branch structure 11 may be in the range of 0.5 mm to 5 mm.

[0044] Optionally, according to the above embodiments of the present application, the width w of the heat dissipation gap 10b may be in the range of 1 mm to 2 mm.

[0045] Preferably, the value range of w / t is 1 to 2. For example, the value of w / t can be 1, 1.2, 1.4, 1.6, 1.8 or 2.

[0046] It should be noted that in the actual welding process, it is generally necessary to use a welding needle to press against the second surface of the welding foot 10, which is the side surface of the welding foot 10 away from the first surface, and heat the welding foot 10 to melt the solder, thereby improving the stability of welding.

[0047] Optionally, the solder foot 10 is provided with a convex portion 111 on the first surface, and the convex portion 111 is used to position the solder foot 10 when the soldering needle heats the solder foot 10, thereby improving the stability of welding. Figure 1 The viewing angle shown is the second surface of the solder foot 10 , and the protrusion 111 is arranged at the bottom of the solder foot 10 which is away from the second surface.

[0048] Specifically, during welding, the welding needle heats the weld foot 10 and also applies external force to the weld foot 10. Therefore, after the solder on the weld foot 10 melts, if no support is provided on the first surface of the weld foot 10, the weld foot 10 may be tilted relative to the surface of the welding plate due to the melting of the solder, thereby causing quality problems caused by uneven distribution of the solder after welding.

[0049] This embodiment is provided with a protrusion 111, which can support the first surface of the solder foot 10 when the solder needle heats the solder foot 10, thereby preventing the solder foot 10 from tilting relative to the surface of the welding plate due to melting of the solder, thereby improving the stability of welding.

[0050] It is worth noting that if the position of the aforementioned protrusion 111 is not set reasonably, the solder foot 10 may also be subjected to unbalanced force when subjected to external force, causing the solder foot 10 to tilt relative to the surface of the welding plate, which will then cause quality problems caused by uneven distribution of solder after welding.

[0051] In order to improve welding quality, optionally, the number of the protrusions 111 can be set to at least 2, for example, the number of the protrusions 111 can be set to 2, 3 or 4.

[0052] Optionally, combined Figure 5 As shown, each convex portion 111 is arranged at intervals along a direction passing through the midpoint of the first surface in the direction of the axis 10a and perpendicular to the direction of the axis 10a. Figure 5 As shown, the midpoint of the aforementioned first surface in the direction of the axis 10a refers to the position at 1 / 2 of the length of the weld foot 10 in the length direction extending along the axis 10a.

[0053] Or, combined Figure 6 As shown, in some other embodiments, the convex portions 111 are arranged at intervals along the axis 10a. In this way, the pressure applied by the soldering pin to the soldering foot 10 can be balanced, the problem of uneven solder distribution can be reduced, and the soldering effect can be improved.

[0054] In order to further improve the stability of the welding pin heating and welding the welding foot 10, the position of the protrusion 111 can be further limited to improve the uniformity of the heat transferred from the welding foot 10 to the glass plate after receiving the heat from the welding pin, thereby improving the welding effect.

[0055] Optionally, combined Figure 5 and Figure 6 As shown, along the arrangement direction of the protrusions 111, the solder foot 10 has a first solder edge 112 and a second solder edge 113, wherein the distance between a protrusion 111 close to the first solder edge 112 and the first solder edge 112 is equal to the distance between another protrusion 111 close to the second solder edge 113 and the second solder edge 113. This allows the force at the edge position of the solder foot 10 to be balanced during welding, further improves the balance of the pressure applied by the welding needle to the solder foot 10, reduces the problem of uneven distribution of solder, and helps to improve the welding effect.

[0056] According to the above embodiment of the present application, preferably, the distance between the first welding edge 112 and the second welding edge 113 is L, the convex portions 111 are arranged equidistantly, and the distance between the convex portions 111 is S, wherein: , n is the number of convex parts.

[0057] It should be noted that The inventor has found through experiments that using the above formula to set the position of the protrusion 111 is helpful to improve the uniformity of heat transfer from the welding pin to the welding foot 10, thereby improving the welding effect.

[0058] Optionally, the protrusion 111 may be implemented as a bump or a column but is not limited thereto.

[0059] Optionally, see Figures 1 to 4 The connection structure 20 may include an avoidance elbow 21, which has a first end and a second end opposite to each other. The first end of the avoidance elbow 21 is connected to the welding foot 10, and the second end of the avoidance elbow 21 is used to be electrically connected to the cable. In the height direction perpendicular to the plane where the welding foot 10 is located, the first end and the second end are staggered, so as to adapt to the installation environment of the heating joint 1 and prevent the cable from interfering with the glass plate.

[0060] Optionally, combined Figure 4 As shown, the connection structure 20 also includes a crimping structure 22, which is arranged at the second end and has a threading hole 22a, which is used to thread and fix the cable, thereby improving the installation stability of the cable. It is worth noting that in this embodiment, since the crimping structure 22 is arranged at the second end of the avoidance elbow 21, the crimping structure can be misaligned with the glass plate in the height direction perpendicular to the plane where the welding foot 10 is located, thereby preventing the crimping structure 22 from interfering with the glass plate and optimizing the structural layout.

[0061] Optionally, the welding foot 10, the avoidance elbow 21 and the crimping structure 22 are integrally formed, which can improve the structural strength of the heating joint 1 and improve production efficiency.

[0062] It is worth noting that the avoidance elbow 21 is in sheet shape during stamping. Furthermore, the avoidance elbow 21 can be bent so that the first end and the second end of the avoidance elbow 21 are staggered in the height direction perpendicular to the plane where the weld leg 10 is located. This process is simple and reliable, and helps to improve production efficiency.

[0063] According to another aspect of the present application, the present application further provides a heatable glass assembly, wherein the heatable glass assembly comprises the above-mentioned heating joint 1 , and the heatable glass assembly further comprises a glass plate, and the heating joint 1 is welded to the glass plate.

[0064] Specifically, the glass plate has a first plate surface and a second plate surface. The first plate surface is the plate surface of the glass plate facing the outside environment after the heatable glass assembly is installed in the vehicle. In other words, the second plate surface is the plate surface of the glass plate facing the interior space of the vehicle. The above-mentioned heating joint 1 can be welded on the second plate surface of the glass plate, and electrically connected to the power supply on the vehicle through an electrical connection structure, so that the glass plate is heated under the action of electrical conduction. More specifically, the glass plate can be, but is not limited to, further provided with a heating structure, the heating structure is electrically connected to the heating joint 1, and the heating joint 1 is used to drive the heating structure to heat the glass plate.

[0065] Optionally, the heating structure may be implemented as, but not limited to, a heating sheet or a heating wire.

[0066] The above-mentioned heatable glass assembly of the present application firstly arranges the welding foot 10 of the heating joint 1 into a plurality of branch structures 11, which can directly reduce the actual contact area between the welding foot 10 and the glass plate during welding, and then reduce the heat required for welding, so that the heat transferred from the welding foot 10 to the glass plate during welding is reduced, and then the temperature difference change on the surface of the glass plate is reduced, thus reducing the local stress change range of the glass plate at the welding position, improving the structural stability of the glass plate at the welding position, and reducing the risk of cracking; at the same time, a heat dissipation gap 10b is provided between each branch structure 11, which helps to improve the heat dissipation effect during welding, reduces heat accumulation, can further reduce the temperature difference change on the surface of the glass plate, and improves the structural stability of the glass plate; in addition, the branch structures 11 on the welding foot 10 are symmetrically arranged about the axis 10a, so that the heat can be symmetrically and evenly transferred through the welding foot 10 during welding, and then the pull-off force and shear force values ​​between the welding foot 10 and the glass can be guaranteed, thereby improving the welding effect.

[0067] The following is the welding verification of the aforementioned heatable glass assembly after the heating joint is improved by the present application. Specifically, the welding parameters of the welding processes of the conventional heating joint and the improved heating joint can be compared by welding the conventional heating joint and the improved heating joint to the glass plate. More specifically, the welding feet of the conventional heating joint and the improved heating joint can be welded under the same voltage value of 2V and welding time of 6s, and the welding temperatures of the two can be compared.

[0068] The comparison results are as follows:

[0069] The welding temperature of the welding foot of the traditional heating joint is about 142.5°C; the welding temperature of the welding foot of the heating joint after improvement in the present application is about 138°C, so the heating joint after improvement in the present application helps to reduce the welding temperature.

[0070] Furthermore, the glass sheets after welding are subjected to an impact test. Specifically, the welding points can be impacted in a simulated loading state:

[0071] Three control groups of conventional heating joints were set up, namely original welding foot 1, original welding foot 2, and original welding foot 3;

[0072] Three control groups of the heating joints of the present application were set up, namely, improved weld foot 1, improved weld foot 2, and improved weld foot 3;

[0073] Fix a weight of 400g-1200g at a height of 400mm, and then impact the front speed control group in turn. Record the impact results as follows:

[0074] When the original welding foot 1 was subjected to the impact of a 900g weight, the glass plate cracked;

[0075] When the original welding foot 2 was impacted by a 1100g weight, the glass plate cracked;

[0076] When the original welding foot 3 was subjected to the impact of a 1000g weight, the glass plate cracked;

[0077] After the improvement, the glass plate did not crack when the weld foot 1 was impacted by a 1200g weight.

[0078] After the improvement, the glass plate did not crack when the weld foot 2 was impacted by a 1200g weight.

[0079] After the improvement, the glass plate did not crack when the weld foot 3 was impacted by a 1200g heavy object.

[0080] From the above impact results, it can be seen that the welding foot of the improved heating joint of the present application can withstand the 1200g impact test, which means that the improved heating joint of the present application helps to improve the strength of the glass plate at the welding position and reduce the risk of glass plate cracking.

[0081] According to another aspect of the present application, the present application also provides a vehicle, which includes the above-mentioned heatable glass assembly.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
