Description

Technical Field

[0001] This utility model relates to the field of door handle technology, and in particular to a split-type door handle. Background Technology

[0002] Door handles are indispensable door accessories, serving both decorative and functional purposes. Normally, door handles don't need to be purchased separately, as most doors sold on the market come with them. Door handles are used very frequently. One-piece door handles are typically made of cast zinc alloy, but this type is expensive. To save on manufacturing costs, door handles are designed as separate units, with two stamped shells welded together to form a complete handle. However, the weld joints need to be polished smooth, which complicates the manufacturing process. To reduce manufacturing steps, screws are used to connect and fix the two shells together.

[0003] However, existing split door handles still have the following problems: they are connected by screws, and the control of tightening torque is crucial. Too little torque will cause loosening, while too much torque will cause the edge of the threaded hole to be recessed, and may also cause deformation or even damage to the panel or the door handle body. The main problem is that there is no supporting structure between the panel and the door handle body. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a split door handle. This utility model supports the panel and the door handle body through a support member, effectively preventing the threaded hole edge from being recessed or damaged due to improper torque during screw connection.

[0005] The technical solution adopted by this utility model is as follows: A split door handle includes a door handle body and a panel. At least one support member is provided between the panel and the door handle body. The door handle body has an installation cavity for the support member to extend into. The panel is connected to the door handle body by fasteners. Each support member has a threaded hole for the fastener to thread into. When the panel is installed on the door handle body, the support member is abutted between the door handle body and the panel. The panel or the door handle body also has an installation hole corresponding to the threaded hole.

[0006] When the panel is installed on the door handle body, the panel is embedded in the mounting cavity.

[0007] The total thickness of the panel and support is the same as the depth of the mounting cavity.

[0008] The support is mounted on the panel, and the mounting hole is formed on the door handle body.

[0009] The support is mounted on the door handle body, and the mounting hole is located on the panel.

[0010] Both the panel and the door handle body are provided with mounting holes, and the threaded holes penetrate the support member.

[0011] The support component is welded to the panel or integrally formed.

[0012] The support member is provided with a boss at the connection between it and the panel.

[0013] The mounting hole has an annular recess at its edge.

[0014] The outer peripheral wall of the panel extends to have a support surface that fits against the inner wall of the mounting cavity.

[0015] The beneficial effects of this utility model are as follows: By setting at least one support member between the door handle body and the panel, and providing threaded holes for fasteners to engage, the support member bears the main force during panel assembly and disassembly, preventing the door handle body or panel from directly bearing tightening torque or impact force. This effectively prevents the threaded hole edge from being recessed or damaged due to improper torque during screw connection. The support member not only provides mechanical support but also ensures a flat contact between the panel and the door handle body, avoiding shaking or abnormal noise caused by loose connection. Furthermore, the door handle body and panel adopt a hollow structure of shell and cover plate, reducing the weight and material consumption of the door handle, making it easier to use and reducing manufacturing costs.

[0021] like Figures 1 to 5 As shown, this is an embodiment of the present invention, a split door handle, including a door handle body 1 and a panel 2. At least one support member 3 is provided between the panel 2 and the door handle body 1. The door handle body 1 has an installation cavity 4 for the support member 3 to extend into. The panel 2 is connected to the door handle body 1 by fasteners. Each support member 3 has a threaded hole 5 for the fastener to thread into. When the panel 2 is installed on the door handle body 1, the support member 3 is abutted between the door handle body 1 and the panel 2. The panel 2 or the door handle body 1 also has an installation hole 6 corresponding to the threaded hole 5.

[0022] The beneficial effects of this design are as follows: By providing at least one support member abutting between the door handle body and the panel, and having a threaded hole on the support member for fastener thread engagement, the support member bears the main force during panel assembly and disassembly, preventing the door handle body or panel from directly bearing tightening torque or impact force. This effectively prevents the threaded hole edge from being recessed or damaged due to improper torque during screw connections. The support member not only provides mechanical support but also ensures flat contact between the panel and the door handle body, avoiding shaking or abnormal noise caused by loose connections. Furthermore, the door handle body and panel adopt a hollow structure of shell and cover plate, reducing the weight and material consumption of the door handle, making it easier to use and lowering manufacturing costs. The support member can be a circular sleeve shape or a prismatic shape with a central opening. This embodiment uses a circular sleeve shape support member, i.e., a bushing with internal threads, which is readily available on the market, easy to process, and inexpensive, thus reducing overall production costs. The fasteners are screws that are readily available in existing technology. The inner wall of the mounting hole is not threaded. As long as the end diameter of the screw is larger than the inner diameter of the mounting hole, the end of the screw can form a stop and limit fit with the mounting hole, thus fixing the door handle body and the panel together.

[0023] In a further configuration, when the panel 2 is installed on the door handle body 1, the panel 2 is embedded in the mounting cavity 4.

[0024] The benefits of this design are as follows: the panel is embedded into the door handle body, reducing gaps, making the panel less likely to fall off or be damaged, and preventing fingers from being pinched during use.

[0025] Furthermore, the total thickness of the panel 2 and the support 3 is the same as the depth of the mounting cavity 4.

[0026] The benefits of this design are as follows: the end face of the panel is coplanar with the end face of the door handle body, further reducing gaps, improving flatness, and increasing aesthetics.

[0027] Further, the support member 3 is disposed on the panel 2, and the mounting hole 6 is formed on the door handle body 1.

[0028] The support member 3 is mounted on the door handle body 1, and the mounting hole 6 is opened on the panel 2.

[0029] Both the panel 2 and the door handle body 1 are provided with mounting holes 6, and the threaded hole 5 passes through the support member 3.

[0030] The advantages of this design are as follows: the support component can be assembled in three different modular ways. The first method involves fixing one end of the support component to the panel and creating a threaded hole at the other end. A corresponding mounting hole is made on the door handle, and a screw is screwed into the threaded hole from the mounting hole side of the door handle. This method allows for the replacement of the support component along with the panel, ensuring the accuracy of the relative positions of the panel and support component, guaranteeing the precision of the connection and the stability of the overall structure, and preventing loosening due to misalignment. The second method involves fixing one end of the support component to the door handle body and creating a threaded hole at the other end. A corresponding mounting hole is made on the panel. This method allows for the replacement of the panel alone; sometimes, only scratches on the panel require replacement, saving maintenance costs. The third method involves a separate structure for the door handle body, support component, and panel. Screws are used to install and fix all three components simultaneously. After the screws pass through, nuts can be used for further fixation. All three components can be replaced individually, offering greater flexibility and better economic benefits.

[0031] Further configuration: the support member 3 is welded to the panel 2 or integrally formed.

[0032] The benefits of this design are as follows: one-piece molding eliminates the need for subsequent welding processes, resulting in higher efficiency; while welding achieves a strong bond between dissimilar materials. Both methods reduce potential points of failure in the production process, improve product consistency and reliability, and help further reduce overall manufacturing costs.

[0033] Furthermore, a boss 9 is provided at the connection between the support member 3 and the panel 2.

[0034] The beneficial effects of this design are as follows: the boss forms a locally thickened and reinforced area, which greatly increases the structural strength, effectively resists the bending moment and stress concentration caused by screw tightening and external impact, prevents the risk of cracking or breaking at the root of the support due to fatigue, and improves the overall durability of the product.

[0035] Furthermore, the mounting hole 6 has an annular recess 7 at its edge.

[0036] The benefits of this design are as follows: the edge of the mounting hole is pre-treated with a ring-shaped recess, which provides stronger structural strength and can prevent larger areas of the door handle body from being dented or damaged. It can also hide the end of the screw, preventing the screw from being uncomfortable to the touch, resulting in a better user experience.

[0037] Furthermore, the outer peripheral wall of the panel 2 extends to have a support surface 8 that fits against the inner wall of the mounting cavity 4.

[0038] The advantages of this design are as follows: the supporting surface provides a larger contact area between the panel and the door handle body, preventing panel tilting and ensuring a more secure installation. Another embodiment uses a panel without a supporting surface, which has the advantages of simple processing and cost-effectiveness.

[0039] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
