Description

Technical Field

[0001] This utility model relates to the field of door lock technology, specifically to a split door handle panel and door handle. Background Technology

[0002] The door handle panel (also known as the door lock panel or handle) is a key component of the door lock system, directly connected to the door lock structure.

[0003] Conventional door handle panels typically consist of a base and an outer cover. The base is fastened to the door panel with fasteners, while the outer cover is attached to the base with threads or fasteners. The outer cover has a panel hole in its center, meaning that the portion of the base directly opposite the panel hole is exposed on the outer surface after the outer cover is attached. With changing interior design styles, the color of the door handle panel needs to coordinate with the overall style of the door panel, requiring electroplating of both the base and the outer cover. However, electroplating both the base and the outer cover significantly increases the cost of the door handle panel.

[0004] Chinese patent CN213980292U discloses a lock panel comprising an outer ring, an inner ring, and a sheet. The inner ring is at least partially installed within the outer ring, and the inner ring has a hole extending through its thickness. A mounting portion is formed in the area of ​​the hole on the inner ring. The sheet covers the mounting portion. The mounting portion is a mounting protrusion with a mounting groove formed on its surface. The sheet covers the mounting groove, which is formed by the recess of the mounting protrusion or by the edge of the mounting protrusion extending away from its surface. The outer ring and inner ring are connected by threads. This lock panel has a complex inner ring mounting portion and external thread structure, resulting in complex inner ring processing steps and high precision requirements. The inner thread of the outer ring also requires a complex tapping process, leading to high overall processing difficulty. Furthermore, the structure of the sheet results in a large amount of waste and low utilization rate.

[0005] In view of this, there is an urgent need to design a split door handle panel to solve the technical defects of existing door handle panels. Utility Model Content

[0006] To solve the above problems, this utility model provides a split door handle panel and door handle.

[0007] In a first aspect, this utility model provides a split door handle panel, including a base and an outer cover. The base has an inner connecting hole, and the outer cover has a through hole facing the inner connecting hole. The panel also includes an inner panel whose outer contour matches the inner contour of the through hole. The inner panel has an outer connecting hole whose inner contour matches the inner contour of the inner connecting hole. The inner wall of the outer connecting hole extends towards the inner connecting hole to form a positioning edge, the depth of which is greater than the depth of the inner connecting hole. The inner panel is fitted onto the base, with the outer connecting hole facing the inner connecting hole. The inner panel is located within the through hole. The outer periphery of the base has a positioning groove, and the inner wall of the outer cover has a positioning block. The outer cover is connected to the base through the engagement of the positioning block and the positioning groove.

[0008] The present invention is further configured such that the positioning edge is a continuous closed structure, and the outer contour of the positioning edge is adapted to the inner contour of the inner connecting hole.

[0009] The present invention is further configured such that the positioning edge is an intermittent structure, and the inner connecting hole is provided with a positioning notch at the position opposite to the positioning edge.

[0010] The present invention is further configured such that the base includes an installation edge, the installation edge is parallel or perpendicular to the inner panel, and the positioning block forms a guide slope on the side near the positioning groove.

[0011] The present invention is further configured such that when the mounting edge is parallel to the inner panel, the positioning groove is provided with a positioning protrusion in the direction close to the inner panel.

[0012] The present invention is further configured such that, when the mounting edge is perpendicular to the inner panel, the groove depth of the positioning groove is less than the thickness of the mounting edge.

[0013] The present invention is further provided with a handle positioning part on the inner wall of the base.

[0014] The present invention is further provided that the base has several fixing holes.

[0015] The present invention is further configured such that the inner connecting hole and the outer connecting hole are round holes or gourd holes; the inner panel is circular, elliptical or rounded rectangle.

[0016] In a second aspect of this utility model, a door handle is provided, including the aforementioned split door handle panel.

[0017] The installation method of this split door handle panel is as follows: Align the outer connecting hole of the inner panel with the inner connecting hole of the base, pass the positioning edge through the inner connecting hole to the back of the base, and use a tool to bend the positioning edge outward to fasten the positioning edge onto the base, so that the inner panel is stably connected to the base; install the base onto the door panel with fasteners, and then install the outer cover onto the base through a snap-fit ​​structure. This connection method enhances the structural stability between the inner panel and the base and prevents the inner panel from loosening or falling off.

[0018] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0019] This utility model door handle panel features a split design, with the inner panel separately mounted and attached to the base. This avoids the need for complex electroplating of the entire door handle panel; only the parts exposed on the outer surface and coordinated with the door panel style (the inner panel and the outer cover) are electroplated, significantly reducing electroplating costs and consequently the overall cost of the door handle panel. The split design and electroplating process of this utility model door handle panel allow for better color coordination with the overall door panel style, enhancing the aesthetics of the door lock system. The independent design of the inner panel and the outer cover also provides greater possibilities in terms of shape and style for the door handle panel.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Example 1

[0038] Combined with appendix Figure 1 To be continued Figure 3This utility model provides a split door handle panel, including a base 1 and an outer cover 2. The base 1 has an inner connecting hole 11, and the outer cover 2 has a through hole 21, which faces the inner connecting hole 11. It also includes an inner panel 3, the outer contour of which matches the inner contour of the through hole 21. The inner panel 3 has an outer connecting hole 31, the inner contour of which matches the inner contour of the inner connecting hole 11. The inner wall of the outer connecting hole 31 faces... The inner connecting hole 11 extends in the direction to form a positioning edge 32. The extension depth of the positioning edge 32 is greater than the depth of the inner connecting hole 11. The inner panel 3 is attached to the base 1. The outer connecting hole 31 is directly opposite the inner connecting hole 11. The inner panel 3 is located in the through hole 21. A positioning groove 12 is provided on the outer periphery of the base 1. A positioning block 22 is provided on the inner wall of the outer cover 2. The outer cover 2 is connected to the base 1 through the cooperation of the positioning block 22 and the positioning groove 12.

[0039] In this embodiment, the installation method of the split door handle panel is as follows: align the outer connecting hole 31 of the inner panel 3 with the inner connecting hole 11 of the base 1, pass the positioning edge 32 through the inner connecting hole 11 to the back of the base 1, and bend the positioning edge 32 outwards using a tool to fasten the positioning edge 32 onto the base 1, so that the inner panel 3 is stably connected to the base 1; then install the base 1 onto the door panel using fasteners, and finally install the outer cover 2 onto the base 1 using a snap-fit ​​structure. This connection method enhances the structural stability between the inner panel 3 and the base 1, preventing the inner panel 3 from loosening or falling off.

[0040] In this embodiment, the base 1, the outer cover 2, and the inner panel 3 are all integrally formed. When the base 1, the outer cover 2, and the inner panel 3 are assembled and installed on the door panel, only the outer cover 2 and the inner panel 3 are exposed on the outer surface. Therefore, it is only necessary to polish and electroplate the outer cover 2 and the inner panel 3.

[0041] In this embodiment, the positioning edge 32 is an intermittent structure, that is, multiple positioning edges 32 are provided along the inner wall of the outer connecting hole 31, and the inner connecting hole 11 is provided with a positioning recess 13 opposite to the positioning edge 32. The positioning recess 13 is used to make way for the positioning edge 32.

[0042] In this embodiment, the base 1 includes a mounting edge 14, which is perpendicular to the inner panel 3. The positioning block 22 forms a guide slope 23 on the side near the positioning groove 12, which facilitates the snap-fit ​​connection of the outer cover 2 to the base 1.

[0043] In this embodiment, the mounting edge 14 is obtained by stamping and folding a sheet metal, the positioning groove 12 is obtained by cutting, and the positioning block 22 is obtained by stamping on the surface of the outer cover 2.

[0044] In this embodiment, when the mounting edge 14 is perpendicular to the inner panel 3, the groove depth of the positioning groove 12 is less than the thickness of the mounting edge 14, so that when the outer cover 2 is connected to the base 1, the positioning block 22 can be directly connected to the positioning groove 12.

[0045] In this embodiment, the inner wall of the base 1 is provided with a handle positioning part 16, which is a reset connection point for handle operation.

[0046] In this embodiment, the base 1 is provided with a plurality of fixing holes 17, which are used to install the base 1 onto the door panel.

[0047] In this embodiment, the inner connecting hole 11 and the outer connecting hole 31 are round holes, wherein the positioning notch 13 on the inner connecting hole 11 is small in size and does not affect the general shape of the inner connecting hole 11; the inner panel 3 is rounded rectangular in shape.

[0048] In this embodiment, the base 1 and the outer cover 2 are generally rounded rectangles.

[0049] This utility model's door handle panel features a split design, with the inner panel 3 separately mounted and attached to the base 1. This avoids the need for complex electroplating of the entire door handle panel; only the parts exposed on the outer surface and coordinated with the door panel style (the inner panel and the outer cover) are electroplated, significantly reducing electroplating costs and consequently lowering the overall cost of the door handle panel. The split design and electroplating process of this utility model's door handle panel allow for better color coordination with the overall door panel style, enhancing the aesthetics of the door lock system. The independent design of the inner panel and the outer cover also provides greater possibilities in terms of shape and style for the door handle panel.

[0050] The inner panel 3, base 1 and outer cover 2 of this utility model door handle panel have a simplified structure, without the need for complicated tapping or forming processes. The inner panel 3 can be quickly and accurately connected to the base 1 through the positioning edge 32, and the outer cover 2 can be quickly connected to the base 1 through the snap-fit ​​structure. The connection structure of the above-mentioned components is easy to form, which reduces the processing difficulty and precision requirements. At the same time, the design of the inner panel can make full use of materials and reduce waste generation.
