Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle body spraying and relates to a hood limiting bracket. Background Art

[0002] During the pre-treatment electrophoretic process, the car body enters and exits the pre-treatment electrophoretic tank at an angle or vertically, and then humps or flips over. This causes the hood (hinge) to have a certain free opening and closing angle and position changes. In addition, the circulating flow of the tank liquid in the pre-treatment electrophoretic tank brings a large impact force. In order to prevent damage to the car body and the hood itself due to the movement of the hood, the hood is usually opened at a certain angle and fixed in a limited position.

[0003] Prior art typically uses a rigid stopper to secure the hood. The upper end is locked to the hood inner panel via a latch, while the lower end is locked to the radiator crossbar. Because the hood is subject to impact, buoyancy, and gravity during the pre-treatment electrophoresis process, controlling and securing the hood opening in this manner can easily cause the hood to deform, impacting vehicle quality.

[0004] In order to solve the above problems, a hood limiting bracket is needed, which can effectively buffer the impact, buoyancy and gravity exerted on the hood during the pre-treatment electrophoresis process, so as to improve the quality of the entire vehicle. Utility Model Content

[0005] In view of this, the utility model provides a hood limit bracket, which can effectively buffer the impact, buoyancy, gravity and other forces exerted on the hood during the pre-treatment electrophoresis process by setting a buffer connection section with elastic force, effectively preventing the front hood from being pulled and deformed due to force after being fixed, and effectively improving the quality of the entire vehicle.

[0006] The utility model discloses a cover limiting bracket, comprising an upper limiting bracket, a lower limiting bracket and a buffer connecting section. The buffer connecting section has elastic force, and the upper limiting bracket and the lower limiting bracket are connected through the buffer connecting section.

[0007] Furthermore, the elastic force of the buffer connection section at least includes an axial elastic component along the axial direction of the buffer connection section and a radial elastic component along the radial direction of the buffer connection section.

[0008] Furthermore, the middle portion of the buffer connection section is in a spiral structure, both ends of the buffer connection section extend radially outward, and the upper limit bracket and the lower limit bracket are respectively installed at the two ends of the buffer connection section.

[0009] Furthermore, the upper limit bracket includes an upper sleeve, an upper connecting rod and an upper clamping portion, the upper connecting rod has a fixed end and a limiting end, and at least two upper connecting rods are provided symmetrically, the fixed ends of the two upper connecting rods are fixed to the upper sleeve, and the limiting ends of the two upper connecting rods are away from each other, so that the upper limit bracket as a whole has a "V"-shaped structure;

[0010] The number of the upper clamping parts is set to two in a one-to-one correspondence with the upper connecting rods, and the two upper clamping parts are respectively fixed to the limiting ends of the two upper connecting rods.

[0011] Furthermore, the lower limit bracket includes a lower sleeve and a lower plug-in rod, the lower plug-in rod has a first plug-in section and a second plug-in section that are perpendicular to each other, and the first plug-in section of the lower plug-in rod is coaxially fixed to the lower sleeve, so that the lower limit bracket as a whole has an "L"-shaped structure.

[0012] Furthermore, the upper clamping portion is in a "U"-shaped structure, and is arranged with its central axis perpendicular to the central axis of the buffer connecting section, and the "U"-shaped openings of the two upper clamping portions are arranged in opposite directions.

[0013] Furthermore, the upper limit bracket is installed on one end of the buffer connection section through the upper sleeve, and the lower limit bracket is installed on the other end of the buffer connection section through the lower sleeve.

The large diameter end of the lower connecting section is connected to the axial end of the lower sleeve, and the first connecting section of the lower connecting rod is connected to the small diameter end of the lower connecting section.

[0015] Furthermore, the lower sleeve, the lower connecting section and the lower connecting rod are integrally formed.

[0017] Beneficial effects of the utility model:

[0018] The utility model discloses a hood limiting bracket, which can effectively buffer the impact, buoyancy, gravity and other forces exerted on the hood during the pre-treatment electrophoresis process by providing a buffer connecting section with elastic force, effectively avoiding the front hood from being pulled and deformed due to the force after being fixed, and effectively improving the quality of the entire vehicle.

[0024] It should be noted that, in the description of this specification, the terms "upper," "lower," "top," "bottom," "inner," "outer," "axial," "radial," "circumferential," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on the present invention. Unless otherwise specified, in this embodiment, "outer" refers to a direction away from itself, which is readily understood by those skilled in the art and will not be elaborated upon here.

[0025] like Figure 1-2As shown, the utility model discloses a hood limiting bracket, comprising an upper limiting bracket 2, a lower limiting bracket 3 and a buffer connecting section 1, wherein the buffer connecting section 1 has an elastic force, and the upper limiting bracket 2 and the lower limiting bracket 3 are connected through the buffer connecting section 1. In this embodiment, the elastic force of the buffer connecting section 1 at least includes an axial elastic component along the axial direction of the buffer connecting section 1 and a radial elastic component along the radial direction of the buffer connecting section 1. As shown in the figure, the buffer connecting section 1 in this embodiment is buffered by elastic force. When the front hood is subjected to force, no matter which direction the force is, it can be compensated and buffered by the axial elastic component along the axial direction of the buffer connecting section 1 and the radial elastic component along the radial direction of the buffer connecting section 1, so as to avoid deformation caused by the pulling of the front hood under force. The provision of elastic force of the buffer connection section 1 can be achieved at least through two aspects: material and structure. In terms of material, for example, rubber material can be used as the manufacturing material. In this embodiment, it is achieved through structural design. The middle part of the buffer connection section 1 of this embodiment is a spiral structure, that is, a spring-like structure is formed in the middle part of the buffer connection section 1. This structure can not only provide axial elastic force and radial elastic force, but also has multiple free displacements, which can effectively compensate for the slight displacement caused by the force during the pre-treatment electrophoresis process of the machine cover, and avoid it from being pulled and deformed; the two ends of the buffer connection section 1 extend radially outward, and the upper limit bracket 2 and the lower limit bracket 3 are respectively installed at the two ends of the buffer connection section 1. The bracket of the utility model not only provides support and fixation for the front machine cover, but also effectively avoids product deformation and improves product quality control.

[0026] like Figure 1 and Figure 3As shown, in this embodiment, the upper limit bracket 2 includes an upper sleeve 201, an upper connecting rod 202 and an upper clamping portion 203. The upper connecting rod 202 has a fixed end and a limiting end. The upper connecting rod 202 is provided in at least two symmetrical portions. The fixed ends of the two upper connecting rods 202 are fixed to the upper sleeve 201, and the limiting ends of the two upper connecting rods 202 are away from each other, so that the upper limit bracket 2 has a "V"-shaped structure as a whole. The number of the upper clamping portions 203 is set to two, corresponding to the number of the upper connecting rods 202. The two upper clamping portions 203 are respectively fixed to the limiting ends of the two upper connecting rods 202. In this embodiment, the upper clamping portion 203 has a "U"-shaped structure. The upper clamping portion 203 is provided in a manner such that the central axis is perpendicular to the central axial direction of the buffer connecting section 1, and the "U"-shaped openings of the two upper clamping portions 203 are provided in opposite directions. As shown in the figure, the upper clamping portion 203 in this embodiment is a horizontal "U"-shaped structure with an opening. The openings of the two upper clamping portions 203 are opposite and both face radially outward along the buffer connecting section 1, that is, horizontally outward in this embodiment. The upper connecting rod 202 is made of a material with a certain elastic deformation ability, such as steel. During use, the staff squeezes the limiting ends of the two upper connecting rods 202 to deform them closer to each other, and then respectively inserts the two upper clamping portions 203 into the holes of the covered inner plate and then releases them, so that the two upper clamping portions 203 move away from each other as the two upper connecting rods 202 rebound, and are then firmly clamped in the machine cover. The limiting ends of the upper connecting rod 202 in this embodiment are bent multiple times to form the upper clamping portion 203. This method makes the upper clamping portion 203 and the upper connecting rod 202 more integrated and the connection more secure.

[0027] like Figure 1 and Figure 4As shown, in this embodiment, the lower limit bracket 3 includes a lower sleeve 301 and a lower plug rod. The lower plug rod has a first plug section 303 and a second plug section 304 that are perpendicular to each other. The first plug section 303 of the lower plug rod is coaxially fixed to the lower sleeve 301, so that the lower limit bracket 3 has an "L"-shaped structure as a whole. In this embodiment, the lower sleeve 301 is provided with a lower connecting section 302. The lower connecting section 302 is a trumpet-shaped structure with a large diameter end and a small diameter end. The large diameter end of the lower connecting section 302 is connected to the axial end of the lower sleeve 301, and the first plug section 303 of the lower plug rod is connected to the small diameter end of the lower connecting section 302. As shown in the figure, the lower plug-in rod is an "L"-shaped rod, which is connected to the lower sleeve 301 through a trumpet-shaped lower connecting section 302. When in use, the second plug-in section 304 is plugged into the hole in the body sheet metal, such as the hole on the water tank crossbeam of the body, and then rotated 90° so that the second plug-in section 304 changes from vertical to horizontal, thus realizing the installation of the lower limit bracket 3 on the body, which is simple and efficient. The lower connecting end is set to be trumpet-shaped, and its variable diameter structure enables the entire lower limit bracket 3 to have a certain buffer displacement space in the axial direction of the elastic buffer section, further avoiding the front hood from being pulled and deformed. In this embodiment, the lower sleeve 301, the lower connecting section 302 and the lower plug-in rod are also integrally formed.

[0028] In this embodiment, the upper limit bracket 2 is mounted on one end of the buffer connection section 1 via the upper sleeve 201, and the lower limit bracket 3 is mounted on the other end of the buffer connection section 1 via the lower sleeve 301. As shown in the figure, both the upper sleeve 201 and the lower sleeve 301 are hollow, sleeve-like structures with axial openings. When in use, they can be directly plugged into the extensions at both ends of the buffer connection section 1, making operation convenient.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
