Description

Technical Field

[0001] This application relates to the field of vehicle component installation tools, and more particularly to an installation fixture for a torsion spring in a vehicle trunk. Background Technology

[0002] When installing the torsion spring from its free state onto the hinge and connecting rod of the suitcase, the operator has to bend over a large distance during the operation and needs to manually overcome the elastic force of the torsion spring, which increases the labor intensity of the operator and leads to low production efficiency. Utility Model Content

[0003] This application provides an installation fixture for a torsion spring in a vehicle trunk, which has a simple structure and is easy to operate.

[0004] To achieve the above objectives, the main technical solutions adopted in this application include:

[0005] This application provides an installation fixture for a torsion spring in a vehicle trunk, including a fixture body, a first connecting rod, and a second connecting rod. Along the extending direction of the fixture body, the first connecting rod and the second connecting rod are spaced apart from each other on the fixture body, and the first connecting rod and the second connecting rod together form a slot with the fixture body.

[0006] The installation fixture proposed in this embodiment has a first connecting rod and a second connecting rod disposed on the fixture body. The first connecting rod, the fixture body, and the second connecting rod form a retaining groove for accommodating a torsion spring and applying torque to the torsion spring. This structure is simple, lightweight, and convenient. When installing the torsion spring, the operator pre-places the installation fixture on the torsion spring, secures the torsion spring in the retaining groove, and then presses the installation fixture downwards to press the torsion spring into the sheet metal hinge, thus achieving the installation of the torsion spring. The entire operation process is simple and convenient, improving assembly efficiency.

[0007] Optionally, along the extending direction of the tooling body, the tooling body has a first end and a second end disposed opposite to each other, and the first connecting rod and the second connecting rod are spaced apart at the first end.

[0008] In the above embodiments, the first link and the second link are located at one end of the tooling body, which can reduce the size of the entire installation tooling and reduce the area occupied.

[0009] Optionally, the slot includes a first slot and a second slot, the first slot and the second slot being located on both sides of the tooling body along a first direction, the first direction being perpendicular to the extension direction of the tooling body.

[0010] In the above embodiments, the installation fixture can install torsion springs on both sides of the vehicle, thus enabling the installation of vehicle torsion springs with a single tool, which is convenient and cost-effective. Optionally, the first connecting rod includes a first part and a second part, which are respectively disposed on both sides of the fixture body along the first direction; the second connecting rod includes a third part and a fourth part, which are respectively disposed on both sides of the fixture body along the first direction, the first part and the third part are spaced apart to form a first slot, and the second part and the fourth part are spaced apart to form a second slot.

[0011] In the above embodiment, the first slot and the second slot are located on both sides of the main body of the tooling along the first direction, so that the mounting tooling can be used for torsion spring installation on the left and right sides of the vehicle.

[0012] Optionally, the axial direction of the first connecting rod is parallel to the axial direction of the second connecting rod and both are perpendicular to the extension direction of the tooling body.

[0013] In the above embodiment, the axial direction of the first link is parallel to the axial direction of the second link and is perpendicular to the extension direction of the tooling body, so that the gap of the tooling body along the first direction is uniform, which makes it convenient for the operator to apply torque to the torsion spring, reduces the chance of the tooling falling off the torsion spring during operation, and makes it easier for the operator to apply torque.

[0014] Optionally, the tooling body, the first connecting rod, and the second connecting rod are all provided with protective layers.

[0015] In the above embodiments, the protective layer on the installation fixture can reduce the damage to the vehicle body caused by operator error or when the installation fixture falls off.

[0016] Optionally, the tooling body includes a first segment and a second segment connected together. The first segment is constructed as an arc segment, and the second segment is constructed as a straight segment. The first connecting rod and the second connecting rod are located in the first segment.

[0017] In the above embodiment, the first segment of the arc provides a fulcrum for the operator to apply torque. When the operator presses and installs the tool, the arc structure forms a lever-like structure, which makes it convenient for the operator to apply force and achieves the effect of saving effort.

[0018] Optionally, the installation fixture also includes a handle connected to the end of the second segment away from the first segment.

[0019] In the above embodiment, the operator applies force to the tooling body through the handle, and then transmits the force to the torsion spring.

[0020] Optionally, the handle includes a third segment, a fourth segment, and a fifth segment connected in sequence. The third segment is connected to the second segment. The third segment, the fourth segment, and the fifth segment are all constructed as arc-shaped segments. The bending direction of the third segment and the bending direction of the fifth segment are opposite to the bending direction of the fourth segment.

[0021] In the above embodiments, the structure is more in line with the operator's usage habits and requires less effort. Furthermore, the handle can overcome the large torque of the torsion spring with less force.

[0022] Optionally, the radius of curvature of the first segment is smaller than the radius of curvature of the fourth segment.

[0023] In the above embodiment, the radius of curvature of the first segment is smaller than that of the fourth segment, which allows the entire installation fixture to be constructed as a lever structure while also making it easy for the operator to hold and apply force.

[0041] In vehicle manufacturing, common tailgate opening methods for sedans include electric, gas spring, and mechanical types. Mechanical tailgates primarily utilize a torsion spring structure. When installing the torsion spring from its free state onto the trunk hinge and its connecting rod, the operator must bend over significantly and manually overcome the spring's elasticity, increasing labor intensity and leading to low production efficiency. Furthermore, the operator has difficulty visually observing the process, resulting in a poor human-machine interface. Additionally, the considerable force exerted during operation can easily scratch the vehicle body.

[0042] In view of this, this application provides an installation fixture for a torsion spring in a vehicle trunk, which is simple in structure, lightweight and convenient, and easy to install, thereby improving assembly efficiency.

[0043] This application provides an installation fixture for a torsion spring in a vehicle trunk, referring to... Figure 1 and Figure 2 The installation fixture includes a fixture body 1, a first connecting rod 2 and a second connecting rod 3. Along the extension direction of the fixture body 1, the first connecting rod 2 and the second connecting rod 3 are spaced apart on the fixture body 1, and the first connecting rod 2 and the second connecting rod 3 together form a slot 4 with the fixture body 1.

[0044] The installation fixture proposed in this embodiment has a first connecting rod 2 and a second connecting rod 3 disposed on the fixture body 1. The first connecting rod 2, the fixture body 1, and the second connecting rod 3 form a retaining groove 4, which is used to accommodate the torsion spring and apply torque to the torsion spring. This structure is simple, lightweight, and convenient. When installing the torsion spring, the operator pre-places the installation fixture on the torsion spring, holds the torsion spring in place with the retaining groove 4, and then presses the installation fixture downwards to press the torsion spring into the sheet metal hinge, thus realizing the installation of the torsion spring. The entire operation process is simple and convenient, improving assembly efficiency.

[0045] It should be noted that the extension direction of the tooling body 1 refers to the direction in which the length of the tooling body 1 extends.

[0046] Optionally, along the extension direction of the tooling body 1, the tooling body 1 has a first end 11 and a second end 12 that are disposed opposite to each other, and the first connecting rod 2 and the second connecting rod 3 are disposed at intervals at the first end 11.

[0047] The first link 2 and the second link 3 are located at one end of the fixture body 1, which can reduce the size of the entire installation fixture and reduce the area occupied. The first link 2 and the second link 3 are located at the first end 11 of the fixture body 1, and the operator can apply torque to the second end 12 to press the torsion spring into the sheet metal hinge.

[0048] Optionally, refer to Figure 1The slot 4 includes a first slot 41 and a second slot 42. The first slot 41 and the second slot 42 are located on both sides of the tooling body 1 along the first direction X, and the first direction X is perpendicular to the extension direction of the tooling body 1.

[0049] The main body of the tooling 1 is provided with a first slot 41 and a second slot 42 on both sides along the first direction X, so that the installation tooling can be used for torsion springs on the left and right sides of the vehicle. The installation tooling can install torsion springs on the left and right sides of the vehicle, thereby realizing the installation of vehicle torsion springs with one tool, which is convenient to operate and saves costs.

[0050] Optionally, refer to Figure 1 The first connecting rod 2 includes a first part 21 and a second part 22, which are respectively disposed on both sides of the tooling body 1 along the first direction X; the second connecting rod 3 includes a third part 31 and a fourth part 32, which are respectively disposed on both sides of the tooling body 1 along the first direction X. The first part 21 and the third part 31 are spaced apart to form a first slot 41, and the second part 22 and the fourth part 32 are spaced apart to form a second slot 42.

[0051] Specifically, the middle of the first connecting rod 2 is connected to the tooling body 1, and the middle of the second connecting rod 3 is connected to the tooling body 1. The tooling body 1 has the first connecting rod 2 and the second connecting rod 3 distributed on both sides along the first direction X, thereby forming the first slot 41 and the second slot 42 on both sides of the tooling body 1.

[0052] The first slot 41 and the second slot 42 are located on both sides of the main body of the tooling along the first direction X, so that the mounting tooling can be used for torsion spring installation on the left and right sides of the vehicle.

[0053] It should be noted that the first direction X can be parallel to the axis of the first link 2 and parallel to the axis of the second link 3, as long as the first direction X is perpendicular to the extension direction of the tooling body 1.

[0054] Optionally, the axial direction of the first link 2 is parallel to the axial direction of the second link 3 and both are perpendicular to the extension direction of the tooling body 1.

[0055] The axial direction of the first connecting rod 2 is parallel to the axial direction of the second connecting rod 3, ensuring that the gap of the tooling body 1 along the first direction X-slot 4 is uniform. This facilitates the operator in applying torque to the torsion spring and reduces the risk of the tooling falling off the torsion spring during operation. The axial directions of both the first connecting rod 2 and the second connecting rod 3 are perpendicular to the extension direction of the tooling body 1, ensuring that the extension direction of the slot 4 is perpendicular to the extension direction of the tooling body 1, further facilitating the operator in applying torque.

[0056] Optionally, refer to Figure 2 The tooling body 1, the first connecting rod 2, and the second connecting rod 3 are all equipped with protective layers 5.

[0057] The protective layer 5 on the installation fixture can reduce damage to the vehicle body caused by operator error or the fixture falling off. Specifically, the protective layer 5 can be a single-sided adhesive fleece cloth, which is pasted and wrapped around the fixture body 1, the first connecting rod 2, and the second connecting rod 3.

[0058] Optionally, refer to Figure 1 The tooling body 1 includes a first section 13 and a second section 14 connected together. The first section 13 is an arc-shaped section, and the second section 14 is a straight section. The first connecting rod 2 and the second connecting rod 3 are located in the first section 13.

[0059] The first segment 13 is an arc-shaped segment. The first link 2 and the second link 3 are located in the first segment 13. When the first link 2 and the second link 3 are engaged with the torsion spring, the first segment 13 provides the operator with a fulcrum for applying torque. When the operator presses the tooling, the arc-shaped structure forms a lever-like structure, which makes it convenient for the operator to apply force. The force applied by the operator is transmitted to the torsion spring along the arc-shaped path, so that the operator can press the torsion spring to the predetermined position with relatively small force, which achieves the effect of saving effort.

[0060] Optionally, refer to Figure 1 The installation fixture also includes a handle 6, which is connected to the end of the second section 14 furthest from the first section 13. The operator applies force to the fixture body 1 through the handle 6, thereby transmitting the force to the torsion spring.

[0061] Optionally, refer to Figure 1 The handle 6 includes a third segment 61, a fourth segment 62 and a fifth segment 63 connected in sequence. The third segment 61 is connected to the second segment 14. The third segment 61, the fourth segment 62 and the fifth segment 63 are all constructed as arc segments. The bending direction of the third segment 61 and the bending direction of the fifth segment 63 are opposite to the bending direction of the fourth segment 62.

[0062] The third segment 61, the fourth segment 62, and the fifth segment 63 are all constructed as arc-shaped segments, and the bending direction of the third segment 61 and the fifth segment 63 are opposite to the bending direction of the fourth segment 62. This structure is more in line with the operator's usage habits and requires less effort. Furthermore, the handle 6 can overcome the large torque of the torsion spring with a smaller force.

[0063] For example, the bending direction of the first segment 13 is opposite to that of the bending direction of the fourth segment 62, and the handle of the installation tool extends in the opposite direction to the main body 1 of the tool, which reduces the curvature of the installation tool in one direction, making the structural design of the installation tool more in line with the operator's usage habits and making it easier for the operator to operate.

[0064] For example, refer to Figure 1The handle 6 also includes a sixth section 64, which is a straight section with an anti-slip part to facilitate gripping by the operator.

[0065] Optionally, the radius of curvature of the first segment 13 is smaller than the radius of curvature of the fourth segment 62. For example, the radius of curvature of the first segment 13 is 75 mm, and the radius of curvature of the fourth segment 62 is 173 mm.

[0066] The curvature radius of the first segment 13 is smaller than that of the fourth segment 62, which allows the entire installation fixture to be constructed as a lever structure while also making it easy for operators to hold and apply force.

[0067] When the mounting tool's slot 4 engages with the torsion spring, the first section 13 provides the operator with a fulcrum for applying torque. When the operator presses down on the mounting tool, the arc-shaped structure of the first section 13 forms a lever-like structure, making it easier for the operator to apply force. The arc-shaped structure of the fourth section 62 makes the handle 6 easier to operate, and the force applied by the operator is transmitted to the torsion spring along the arc-shaped path, allowing the operator to press the torsion spring to the predetermined position with relatively small force, achieving a labor-saving effect.

[0068] Specifically, when installing the torsion spring on the tailgate, the operator first places the installation fixture on the torsion spring, aligning it with the sheet metal hinge, ensuring that the slot 4 of the installation fixture is in full contact with the torsion spring. Then, the operator presses the installation fixture downwards using a lever principle, pressing the torsion spring into the tailgate hinge. After that, the installation fixture is removed, thus improving installation efficiency. It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.
