Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and more specifically, to a front mounting device for an electric vehicle. Background Technology

[0002] Electric vehicles are an important tool for daily travel, and hooks are installed at the front of the vehicle to hang items. Currently, many electric vehicle hooks use spring-controlled structures to achieve concealed or movable functions. These structures not only have more components and more complex assembly processes, increasing production costs, but the springs are also prone to elasticity decay after long-term use, leading to poor hook return or inability to lock, directly affecting their service life and reliability. On the other hand, the front panel of the electric vehicle, the mounting base for existing hooks, is a key structural component at the front of the vehicle. Its material selection and design directly affect the stability and durability of the hook device. Some front panel components are made of plastic, which, while lightweight, is prone to warping and deformation; while metal materials, although strong, lack cushioning performance and have corrosion resistance issues. The hook device is continuously subjected to vibration and occasional impacts during vehicle operation. If the front panel is too rigid and lacks elastic cushioning, stress concentration will occur at the connection point between the front panel and the hook, accelerating fatigue damage to the hook.

[0003] Therefore, there is a need for a highly practical, long-lasting, safe and reliable front-mounted device for electric vehicles. Utility Model Content

[0004] The problem solved by this utility model is to provide a front-mounted device for electric vehicles that has a long service life and is safe and reliable.

[0005] To solve the above problems, the present invention adopts the following technical solution: a front mounting device for an electric vehicle, the front mounting device comprising: a front enclosure made of metal material, the front enclosure having a first mounting hole; a liner sleeve disposed in the first mounting hole with one end extending out of the first mounting hole; and a hook fixed to the outside of the front enclosure and connected to the end of the liner sleeve extending out of the first mounting hole, the hook being used to carry items.

[0006] Furthermore, the other end of the liner is fixed to the base, which is located inside the front bulkhead.

[0007] Furthermore, the liner kit has a snap-fit ​​groove in the radial direction, through which the liner kit snaps into the first mounting hole.

[0008] Furthermore, the end of the liner extending out of the first mounting hole is provided with a socket, and the hook is provided with a socket hole. The socket and the socket hole cooperate to fix the hook onto the liner.

[0009] Furthermore, a fixing hole is provided at the center of the socket, and the hook is fixed in the fixing hole by bolts.

[0010] Furthermore, a T-shaped bushing is provided inside the fixing hole. The T-shaped bushing includes an abutting part and a central hole part. The abutting part extends out of the fixing hole and abuts against the sleeve hole, while the central hole part is located inside the fixing hole and abuts against the fixing hole.

[0011] Furthermore, the hook component has a snap-fit ​​part at the other end relative to the socket, and the front part has a second mounting hole. The second mounting hole cooperates with the snap-fit ​​part to fix the hook component to the front part.

[0012] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: 1. By installing a rubber connector between the front of the electric vehicle and the hook, the vibration and impact generated during vehicle operation are absorbed and buffered, avoiding direct hard friction and collision between metal parts. This fundamentally reduces wear on the connection between the front and the hook, and greatly extends the overall service life of the hook device.

[0013] 2. Firstly, the bushing and hook are initially fixed through the engagement of the socket hole, and then a double connection is formed by tightening the bolts into the fixing holes, ensuring a tight connection between the hook and the bushing and preventing loosening due to shaking under load. Secondly, the T-shaped bushing further ensures stress distribution, not only dispersing the bolt tightening force and preventing the bushing from deforming due to localized pressure, but also strengthening the stability of the bolt connection through the rigid bushing, preventing connection failure due to rubber aging after long-term use. In addition, the snap-fit ​​part of the hook engages with the second mounting hole of the front part to form an additional fixing point, distributing the load on the hook to the two mounting hole areas of the front part, reducing single-point stress concentration, and further improving the overall structure's anti-shaking ability.

Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] In this embodiment, in order to facilitate the description of the specific structure, the components are limited in terms of direction and location, such as the rear end and both sides. However, the structure itself is not limited to the directions and locations defined in this embodiment.

[0018] See Figures 1-9 See Figure 1 This is a structural schematic diagram of a front-mounted mounting device for an electric vehicle provided in an embodiment of this utility model. Combined with... Figures 2-9 Specifically, the front mounting device includes a front section 1, a liner 3, and a hook 4. The liner 3 is located in the first mounting hole 2 of the front section 1, with one end extending out of the first mounting hole 2 to connect to the hook 4. The hook 3 is fixed to the outside of the front section 1.

[0019] Since the front section 1 is made of metal, it has high structural strength, while the bushing 3 can be made of rubber, silicone, or plastic, such as natural rubber, thermoplastic polyurethane, or EPDM rubber. This solution utilizes the elasticity and damping properties of the bushing 3 to absorb and buffer vibrations and impacts generated during the load-bearing process of the hook 4 and vehicle operation. This avoids direct hard contact and friction between the hook 4 and the front section 1, especially friction between the fixing components supporting the hook 4 and the hook itself. This reduces the wear rate of the connection points and fundamentally extends the service life of the entire hook-up device.

[0020] Further, see Figure 2 and Figure 5 The other end of the liner 3 is fixed to the base 5, which is located inside the front part 1.

[0021] The base 5 is used to provide additional internal support and positioning for the liner kit 3.

[0022] Further, see Figures 2-4 The liner 3 has a snap-fit ​​groove 6 in the radial direction, and the liner 3 is snapped into the first mounting hole 2 through the snap-fit ​​groove 6.

[0023] The snap-fit ​​groove 6 engages with the edge of the first mounting hole 2 on the front enclosure 1, achieving initial fixation of the liner 3 on the front enclosure 1. Simultaneously, the design of the snap-fit ​​groove 6 allows the liner 3 to undergo controllable elastic deformation under stress. When the hook 4 carries items or a vehicle travels on bumpy roads, impacts and vibrations are transmitted to the liner 3 through the hook 4. At this time, the elasticity of the rubber material and the groove structure work together to effectively absorb and buffer this energy, avoiding rigid contact and direct friction between the metal front enclosure 1 and the hook 4, thereby significantly reducing wear and improving the device's durability.

[0024] Further, see Figure 3 and Figure 4 The lining kit 3 is provided with a socket 7 and the hook 4 is provided with a socket hole 8. The socket 7 and the socket hole 8 cooperate to fix the hook 4 onto the lining kit 3.

[0025] The hook 4 and the liner 3 are connected by engaging the socket 8 with the socket 7 of the liner 34. To further enhance the reliability of the connection, the two can be locked together by screwing the bolt 10 through the hook 4 into the fixing hole 9 of the liner 3.

[0026] Preferred, see Figures 3-6 A T-shaped bushing 11 may also be provided inside the fixing hole 9. The T-shaped bushing 11 includes an abutting part 12 and a central hole part 13. The abutting part 12 extends out of the fixing hole 9 and abuts against the sleeve hole 8, increasing the contact area. The central hole 13 is located inside the fixing hole 9 and abuts against the fixing hole 9, effectively preventing the bolt 10 from causing cutting damage to the rubber body.

[0027] For example, the bushing 3 has a through hole at its center, and the central hole 13 is a cylindrical structure set inside the through hole. The cylindrical shape is adapted to the through hole and can be configured as an interference fit. The central hole 13 and the bushing 3 are bonded together with a special adhesive. In addition, the inner surface of the cylindrical tube is threaded, so as to connect the bushing 3 and the hook 4 with bolts 10.

[0028] To illustrate again, the structure of the abutment part 12 is a flange provided on the outside of the central hole part 13, and its shape is adapted to the shape of the socket hole 8. Through the structural cooperation between the flange and the socket hole 8, the bushing part 3 will not directly contact the hook part 4, thus ensuring the service life of the entire device.

[0029] Further, see Figure 1 , Figure 8 and Figure 9 The hook part 4 has a snap-fit ​​part 14 at the other end relative to the socket 8, and the front part 1 has a second mounting hole 15 at the corresponding position.

[0030] For example, the snap-fit ​​part 14 can be a spherical protrusion or a cylindrical snap pin located at the end of the hook part 4, and the second mounting hole 15 is a circular or square snap hole integrally stamped with the front part 1. Through the interference fit or elastic snap-fit ​​between the protrusion and the snap hole, the end of the hook part 4 can be quickly fixed, effectively suppressing the lever effect sway of the hook part 4 as a cantilever beam under load.

[0031] Specifically, by placing the bushing 3 between the metal front bulkhead 1 and the hook 4, a transition from a rigid connection to an elastic connection is achieved. Utilizing the elasticity and damping properties of the rubber material, vibrations and impacts generated during vehicle operation are effectively absorbed, avoiding direct friction and wear between metal components. The snap-fit ​​fixing of the bushing 3, the engagement of the socket 7 and the socket hole 8, the tightening of the bolt 10, and the engagement of the distal snap-fit ​​part 14 and the second mounting hole 15 constitute a multi-point, multi-dimensional stable fixing system, improving the stability of the hook 4 under dynamic loads. Considering the specific usage of the hook device, when it is necessary to replace the bushing 3 due to long-term use and aging, this technical solution, through the detachable snap-fit ​​between the bushing 3 and the front bulkhead 1, and the detachable bolt 10 connection with the hook 4, reduces the difficulty of maintenance and replacement. Only the bolt 10 needs to be removed to separate the hook 4 from the bushing 3, and then the bushing 3 can be removed from the first mounting hole 2 for replacement. It is not necessary to replace the entire front bulkhead 1 or the hook 4, extending the overall service life of the hook device and reducing maintenance costs.

[0032] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
