Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and in particular to an integrated die-cast handlebar bracket and electric vehicle. Background Technology

[0002] Currently, the typical handlebar bracket structure for electric two-wheelers usually includes bent tubular components. Stamped parts are installed at corresponding positions on the tubular components using fasteners or welding to connect with other accessories, forming a support structure. A plastic outer shell is then added to the outside of the support structure to improve aesthetics. Existing handlebar bracket structures have the following drawbacks: First, the tubular wall thickness is relatively thin (e.g., less than 2.0mm), making it prone to bending, deformation, or even breakage during sharp turns or collisions. Second, because multiple stamped parts need to be installed on the tubular material, application concentration is likely at the joints, resulting in insufficient structural strength. Third, adding a plastic outer shell to the bracket support structure complicates assembly and reduces the proportion of metal components. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an integrated die-cast handlebar bracket and electric vehicle, aiming to improve the structural strength and ease of assembly of the handlebar.

[0004] The technical solution adopted in this utility model is as follows:

[0008] The first mounting hole is used to assemble the second pressure plate, which together with the second wire passage forms a second wire passage channel.

[0009] The third mounting hole is used to assemble the column mounting plate.

[0030] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0031] Example 1

[0032] See Figures 1 to 4 This embodiment provides an integrated die-cast handlebar bracket, including a main body 1 and a handlebar 4;

[0033] On the one hand, the main body 1 is integrally formed using an integrated molding process and is used as a functional component of the handlebar, while also being used directly as an appearance component; the main body 1 has an axisymmetric structure, with threaded holes 102 integrally formed at both ends, and the handlebar 4 has an external thread that mates with the threaded holes 102 at one end.

[0034] On the other hand, the central area on the lower side of the main body 1 is integrally molded with a mounting position, which includes:

[0035] The first mounting hole 107 and the first wire passage 106 are used to assemble the first wire pressure plate 6, which together with the first wire passage 106 forms a first wire passage channel, which can be used to pass the switch wire harness.

[0036] The second mounting hole 104 and the second cable passage 103, the first mounting hole 107 is used to assemble the second pressure plate 7, which is used to form a second cable passage with the second cable passage 103, and can be used to pass the disc brake oil line.

[0037] The third mounting hole 105 is used to assemble the column mounting plate 8.

[0038] Compared with traditional tubular structures, the main component 1 of this embodiment greatly improves functionality and aesthetics. The integrated mounting position in the central area enables support and installation functions such as wire routing and connection, enhancing the connection strength between the main component and the pressure plate and column mounting plate. This avoids problems such as weak connections and stress concentration caused by the use of stamped parts in traditional solutions.

[0039] The main body 1 is preferably configured as a triangle, trapezoid, or ellipse.

[0040] The central region is preferably trapezoidal and has a concave structure, thereby forming a protrusion 108 on the corresponding area on the upper side of the main body 1. The concave structure can maximize structural stability and increase the space for accommodating the wire harness.

[0041] As a preferred embodiment, the handle 4 is provided with a first positioning hole 3, which is used for positioning and installing the switch assembly 9. The switch assembly 9 has different structural configurations depending on the vehicle model, and mainly integrates switching units for lights, speed control, alarms, etc. The switch assembly 9 is composed of various switch units assembled into a module, and the outer side of the module is provided with a positioning post that mates with the first positioning hole 3, which facilitates positioning and installation through plug-in connection.

The positioning and installation are facilitated by plugging and connecting the two parts.

[0043] This embodiment optimizes the structural design and installation process by setting the first positioning hole 3 and the second positioning hole 2, eliminating the need for additional stamped parts to connect the switch assembly 9 and the disc brake upper pump 5.

[0044] Specifically, the handlebar 4 is tubular. When assembling the handlebar assembly using the die-cast handlebar bracket of this embodiment, a plastic handlebar glove 10 is provided on the handlebar 4 to increase friction. For ease of viewing and understanding, as... Figure 4 The glove on the right handle is hidden in the middle.

[0045] As a preferred embodiment, the main body 1 is provided with two hollow areas 101, and the two hollow areas 101 are symmetrically arranged with the center line of the main body 1 as the axis of symmetry.

[0046] The hollowed-out area design in this embodiment further reduces the weight of the handlebar bracket, meeting the requirements for lightweight design and use. It also further improves the aesthetics.

[0047] As a preferred method, the handle 4 is threaded and glued to the main body 1, that is, an adhesive layer is applied to the threaded hole or external thread, and then the threaded connection is made, which improves the stability of the connection structure and avoids the process defects of welding.

[0048] Specifically, the first mounting holes 107 are symmetrically arranged on both sides of the central region, with each side including two mounting holes spaced apart; the first wire groove 106 is located between the two spaced mounting holes.

[0049] Specifically, the second mounting holes 104 are symmetrically arranged on both sides of the central region, with one mounting hole on each side; the second wire groove 103 is located between a mounting hole and the edge of the central region.

[0050] Specifically, the third mounting hole 105 is located within the inner circle of the first mounting hole 107 and the second mounting hole 104, and includes four mounting holes distributed circumferentially.

[0051] Specifically, the integral molding process preferably adopts the die casting process, and the main body 1 is made of aluminum alloy.
