[0034] See also Figure 1 , Figure 2 and Figure 3 In one embodiment of the present application, a tension spring fixing seat 1 is provided, comprising a seat body 12 and an action member 13. The seat body 12 has a mounting arm 121 for sleeve-engaging the tension spring 2 along the axial direction. The mounting arm 121 is arranged in a ring around a preset axial direction, and the seat body 12 is controlled to move along the preset axial direction. The action member 13 supports the mounting arm 121, and the action member 13 is configured to provide a first action force to the mounting arm 121 to make the mounting arm 121 expand radially perpendicular to the preset axial direction during the movement of the seat body 12 along the preset axial direction.

[0035] The tension spring fixing seat 1 is connected to the tailgate or the car body during actual operation. The tension spring 2 is sleeved on the tension spring 2 mounting arm 121. The other end of the tension spring 2 is connected to the car body or the tailgate. When the tailgate is opened, the tension spring 2 is pulled, and the seat body 12 moves along the preset axial direction under the pull of the tension spring 2. During the movement of the seat body 12 along the preset axial direction, the action member 13 provides a first action force that expands radially outward to the mounting arm 121 to open the mounting arm 121, so that the overall outer diameter of the mounting arm 121 increases. When the outer diameter of the mounting arm 121 increases, the tension spring 2 sleeved on the mounting arm 121 is more tightly sleeved with the mounting arm 121, thereby preventing the tension spring 2 from falling off. When the tension spring 2 returns, it drives the seat body 12 to return to the initial position together. Compared with the prior art, by providing the action member 13 to provide the first action force to increase the outer diameter of the mounting arm 121 when the seat body 12 is pulled, the tension spring 2 can be effectively prevented from falling off the mounting arm 121, and the disassembly and assembly of the tension spring 2 is also facilitated.

[0036] It should be noted that the mounting arms 121 are arranged in a ring shape around a preset axial direction, so that the mounting arms 121 are thin-walled. At this time, the mounting arms 121 can expand radially outward under the first force. Figure 4 and Figure 5 An internal thread matching the tension spring 2 is arranged on the outer wall of the mounting arm 121 around a preset axial direction, and the tension spring 2 is connected to the internal thread of the mounting arm 121. Compared with the case where the tension spring 2 is directly connected to the outer wall of the mounting arm 121, the connection is more secure.

[0037] It can be understood that when the tailgate is closed, the tension spring 2 can generate a force under its own restoring force to move the seat body 12 along a preset axial direction, so that the seat body 12 returns to its initial position. The seat body 12 in the initial position has a loose connection between its mounting arm 121 and the tension spring 2, which facilitates the disassembly and assembly of the tension spring 2.

[0038] Preferably, the tension spring fixing seat 1 further comprises a connecting member 11, and the action member 13 is arranged on the connecting member 11. The tension spring fixing seat is connected to the vehicle through the connecting member 11. Of course, the action member can also be directly connected to the vehicle, but the on-site installation is more complicated, the installation efficiency is low, and the adaptability to the existing vehicle structure is low.

[0039] In order to realize that the action member 13 can generate the first action force when the seat body 12 moves along the preset axial direction, the action member 13 may include a position sensor and a cylinder. The cylinder is arranged on the connecting member 11 and can be extended and retracted in the radial direction. The position sensor is arranged on the connecting member 11. The mounting arm 121 is supported on the telescopic end of the cylinder. The position sensor detects the axial distance between the connecting member 11 and the seat body 12. When the position sensor detects that the seat body 12 is displaced relative to the connecting member 11 in the preset axial direction, the cylinder is linked to extend the side length to generate the first action force acting on the mounting arm 121. Of course, the scheme in the following embodiment can also be adopted to enable the action member 13 to generate the first action force.

[0040] In some embodiments, the action member 13 is configured to be compressed during the movement of the seat body 12 along the preset axial direction, and the compressed action member 13 can provide a first action force. At this time, when the seat body 12 is controlled to move along the preset axis, the action member 13 is compressed and linked to generate the first action force. In this way, there is no need to use a control device, which simplifies the cost of the tension spring fixing seat 1 and also increases the service life of the tension spring fixing seat 1.

[0041] For example, the action member 13 is an action block made of a resin, rubber or airbag that expands under pressure. The action block is arranged on the connecting member 11. The radial side of the action block supports the mounting arm 121. The axial end face of the action block abuts against the axial inner side of the seat body 12. When the seat body 12 moves along the preset axial direction, the axial inner side of the seat body 12 presses down the axial end face of the action block, so that the action block expands radially (at this time, the axial length of the action block becomes shorter and the radial length becomes longer), so that the radial side of the action block can provide a first action force to the mounting arm 121 to open the mounting arm 121. It can be understood that when the seat body 12 returns to the initial position, the pressure applied to the action block disappears, and the action block can return to the initial state (the axial length becomes longer and the radial length becomes smaller).

[0042] Specifically in the embodiment, the action member 13 includes a connecting portion 131, both ends of which are rotatably connected to the connecting member 11 and the mounting arm 121 along a direction perpendicular to the preset axial direction, and are configured to be controlled to rotate in a plane parallel to the preset axial direction, and the mounting arm 121 is supported by the connecting portion 131. The connecting portion 131 is pressed and rotated during the movement of the seat body 12 along the preset axial direction, and the rotating connecting portion 131 can provide a first action force.

[0043] During actual operation, when the seat body 12 moves along the preset axial direction, pressure is applied to the connecting portion 131 through the mounting arm 121 of the seat body 12. Since both ends of the connecting portion 131 are rotatable, as the mounting arm 121 continues to move in the preset axial direction, the two ends of the connecting portion 131 gradually become flat (located in the same radial direction). During the rotation of the connecting portion 131, a first force is generated, causing the mounting arm 121 to expand outward in the radial direction and open.

[0044] The connecting portion 131 may be a circular ring plate, the inner side of which is rotatably connected to the connecting member 11, and the outer side of which is rotatably connected to the mounting arm 121. When the seat body 12 moves along a preset axial direction, the outer side of the ring is pressed to rotate the circular ring plate and provide a first force to the mounting arm 121.

[0045] Preferably, see Figure 3 The connecting portion 131 includes a plurality of connecting rods 1311, which are arranged at intervals around a preset axial direction. Each connecting rod 1311 can rotatably connect the mounting arm 121 and the connecting member 11. Each connecting rod 1311 is synchronously compressed and rotated during the movement of the seat body 12 along the preset axial direction to provide a first force to the mounting arm 121.

[0046] In actual operation, when the seat body 122 moves along the preset axial direction, the installation arm 121 presses down each connecting rod 1311 at the same time, and each connecting rod 1311 rotates at the same time to provide multiple radial effects on the installation arm 121, so that the installation arm 121 expands radially outward.

[0047] Specifically in the embodiment, the connecting member 11 includes a connecting shaft 111 extending in the opposite direction of a preset axial direction and a shoulder 112 arranged on the connecting shaft 111, the acting member 13 also includes a skeleton 132, and the tension spring fixing seat 1 also includes an elastic member 14, the skeleton 132 is movably sleeved on the connecting shaft 111, the elastic member 14 is sleeved on the connecting shaft 111 and limited between the skeleton 132 and the shoulder 112, and the connecting rod 1311 is rotatably connected to the skeleton 132. During the movement of the seat body 12 along the preset axial direction, the elastic member 14 provides a second force that causes the skeleton 132 to move in a direction opposite to the preset axial direction.

[0048] During actual operation, when the seat body 12 moves along the preset axial direction, since the connecting rod 1311 is connected to the skeleton 132, and the skeleton 132 can move along the connecting axis 111, when the mounting arm 121 presses down the connecting rod 1311, the pressure is transmitted to the skeleton 132 through the connecting rod 1311, so that the skeleton 132 has a tendency to move along the preset axial direction. At this time, since the elastic member 14 exerts a second force opposite to the preset axial direction on the skeleton 132, the skeleton 132 does not move under the balance of pressure and the second force, and the end of the connecting rod 1311 connected to the mounting arm 121 rotates as the mounting arm 121 moves, and the two ends of the connecting rod 1311 gradually become flat (located on the same radial direction), thereby spreading the mounting arm 121.

[0049] When the seat body 12 returns to the initial position under the restoring force of the tension spring 2, the connecting rod 1311 rotates in the opposite direction, and the pressure acting on the frame 132 gradually decreases. When the pressure decreases to a certain value, the elastic member 14 returns to the initial position. It should be noted that since the seat body 12 is supported on the connecting rod 1311 through the mounting arm 121, that is, supported on the frame 132, and the frame 132 is mainly maintained in a balanced position by the pre-tightening force provided by the elastic member 14, that is, the seat body 12 is supported on the elastic member 14, and the elastic member 14 is supported on the connecting member 11, the seat body 12 and the connecting member 11 are elastically connected, so that when the tension spring 2 is stretched, the movement of the seat body 12 will not cause a rigid impact on the connecting member 11, which helps to protect the entire tension spring fixing seat 1.

[0050] Of course, in other embodiments, the feasibility of directly fixing and sleeve-connecting the frame 132 on the connecting shaft 111 without providing the shoulder 112 and the elastic member 14 is not excluded.

[0051] The connecting rod 1311 can be rotatably connected to the connecting member 11 and the mounting arm 121 via a pin. The specific method for realizing the rotatable connection of the connecting rod 1311 is not limited here.

[0052] Among them, see Figure 2 and Figure 6 When the shoulder 112 is located on the same side of the frame 132 as the preset axial direction, the elastic member 14 is a compression spring. When the seat body 12 moves along the preset axial direction, the compression spring is compressed and provides a supporting force to keep the frame 132 in a balanced position. When the shoulder 112 is located on the opposite side of the frame 132 from the preset axial direction, the elastic member 14 is a tension spring 2, and the tension spring 2 is connected to the shoulder 112. When the seat body 12 moves along the preset axial direction, the tension spring 2 is compressed and provides a pulling force to keep the frame 132 in a balanced position.

[0053] Specifically in the embodiment, see Figure 2 and Figure 6The connecting shaft 111 penetrates the seat body 12, and the connecting shaft 111 has a matching portion 1111 on the side of the seat body 12 away from the mounting arm 121. In actual operation, the matching portion 1111 is used to match with the fixing head, and the fixing head is used to install the entire tension spring fixing seat 1 on the tailgate or the car body.

[0054] The matching portion 1111 may be an external thread or an internal thread, etc. The fixing head may refer to the prior art, such as a ball head fixing head, which is not specifically limited here.

[0055] In some embodiments, see Figure 2 and Figure 6 The connecting member 11 also includes a connecting head 113 connected to one end of the connecting shaft 111 . The connecting head 113 is located on one side of the mounting arm 121 in a preset axial direction. The connecting head 113 is used to sleeve the catheter 15 .

[0056] In actual operation, the connector 113 is used to sleeve the conduit 15 , and the tension spring 2 is sleeved outside the conduit 15 . The conduit 15 can guide the extension direction of the tension spring 2 .

[0057] Further, see Figure 2 and Figure 6 A groove 1131 is arranged on the outer wall of the connector 113 arranged around the preset axial direction. At this time, when the connector 113 is sleeved with the conduit 15, the air pressure in the groove 1131 is high, so that the connector 113 is not easy to be disengaged from the conduit 15.

[0058] Further, see Figure 2 and Figure 4 The tension spring fixing seat 1 further comprises the above-mentioned conduit 15, which is sleeved on the connector 113, and the outer diameter of the conduit 15 is smaller than the outer diameter of the mounting arm 121. In this way, the tension spring 2 can be conveniently mounted on the mounting arm 121.

[0059] In some embodiments, see Figure 4 and Figure 5 The mounting arm 121 includes a plurality of cantilevers 1211, which are arranged at intervals around a preset axial direction. The cantilevers 1211 are supported on an action member 13, and the action member 13 is constructed to provide a first action force to each cantilever 1211 so that the cantilever 1211 expands radially outward perpendicular to the preset axial direction during the movement of the seat body 12 along the preset axial direction.

[0060] At this time, the cantilevers 1211 are spaced apart from each other, and each cantilever 1211 is a cantilever 1211 beam structure, so that the mounting arm 121 can be easily opened by the action member 13 .

[0061] Specifically, each cantilever 1211 is rotatably connected to a connecting rod 1311 in a one-to-one correspondence, and each rotating rod provides a force to the corresponding cantilever 1211 to make the cantilever 1211 expand radially outward when the seat body 12 moves along a preset axial direction.

[0062] Of course, in other embodiments, the mounting arm 121 may be made of a material having a certain elasticity, such as plastic, so that the mounting arm 121 can be easily expanded.

[0063] In some embodiments, see Figure 2 and Figure 6 The seat body 12 includes a seat body 122 , a mounting arm 121 disposed on the seat body 122 , and a connecting block 123 . The connecting block 123 connects the seat body 122 and the mounting arm 121 , and the action member 13 supports and connects the connecting block 123 .

[0064] At this time, the seat body 12 is supported on the action member 13 through the connection block 123. Since the connection block 123 is connected to both the seat body 122 and the mounting arm 121, the support of the seat body 12 can be made more stable.

[0065] Specifically, when the actuator 13 includes the connecting portion 131 , the connecting portion 131 is rotatably connected to the connecting block 123 .

[0066] Specifically, when the mounting arm 121 includes a plurality of cantilevers 1211 , the connecting blocks 123 include a plurality of cantilevers 1211 , one connecting block 123 correspondingly connects one cantilever 1211 and the seat body 122 , and one connecting rod 1311 correspondingly rotatably connects one connecting block 123 .

[0067] The tension spring fixing seat 1 provided in the embodiment of the present application is installed on the tailgate or the car body in actual operation. The tension spring 2 is sleeved on the tension spring 2 mounting arm 121. The other end of the tension spring 2 is connected to the car body or the tailgate. When the tailgate is opened, the tension spring 2 is pulled, and the seat body 12 moves along the preset axial direction under the pull of the tension spring 2. In the process of the seat body 12 moving along the preset axial direction, the action member 13 provides a first action force that expands radially outward to the mounting arm 121 to open the mounting arm 121, so that the overall outer diameter of the mounting arm 121 increases. When the outer diameter of the mounting arm 121 increases, the tension spring 2 sleeved on the mounting arm 121 is more tightly sleeved with the mounting arm 121, thereby preventing the tension spring 2 from falling off. Compared with the prior art, by providing the action member 13 to provide the first action force to increase the outer diameter of the mounting arm 121 when the seat body 12 is pulled, the tension spring 2 can be effectively prevented from falling off from the mounting arm 121.

[0068] In addition, an embodiment of the present application further provides a support rod, including a tension spring 2 and a tension spring fixing seat 1 as provided in any of the above embodiments, and the tension spring 2 is sleeved on the mounting arm 121. Since the support rod includes the above tension spring fixing seat 1, it includes all the beneficial effects of the above embodiments, which will not be repeated here.

[0069] Of course, the support rod may also include other components such as a top pipe, a screw rod, a motor, etc., and with reference to the prior art, no limitation or elaboration is made here.

[0070] In addition, an embodiment of the present application further provides a car, comprising a car body, a tailgate and the above-mentioned support rod, wherein the tailgate is rotatably connected to the car body, one end of the support rod is connected to the car body, and the other end of the support rod is connected to the tailgate. Since the car comprises the above-mentioned support rod, it includes all the beneficial effects of the above-mentioned embodiments, which will not be repeated here.

[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
