Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a stabilizer bar. In addition, the utility model also relates to a vehicle. Background Art

[0002] As vehicles become increasingly intelligent, the use of smart electric accessories is becoming increasingly widespread. As a key opening and closing component in electric tailgate systems, gas spring stabilizers are widely used in these systems. Gradually replacing traditional manual tailgate opening and closing systems, stabilizers assist electric actuators in opening and closing tailgates, providing a positive user experience and effectively meeting user needs.

[0003] Currently, most stabilizer bars on the market use a gas spring as the connecting component between the upper and lower ball-and-socket connectors, with a gas spring positioned between the upper and lower sockets. Because the gas spring contains high-pressure gas, its pressure fluctuates significantly under high and low temperature conditions, which in turn changes the force applied to the stabilizer bar and affects its effectiveness. For example, at low temperatures, the gas in the gas spring contracts, reducing the supporting force and potentially causing the tailgate to drop. At high temperatures, the gas in the gas spring expands, increasing the force and potentially causing the tailgate to open and rise.

[0004] At the same time, the gas spring contains sealing rubber, which forms an interference fit with the piston rod. This creates significant resistance during expansion and contraction, and is prone to friction noise. Furthermore, the gas spring itself is complex in its manufacturing process, making it difficult to manufacture and relatively expensive. Furthermore, because the outer sleeve and connector of the balance bar are not completely sealed, water, such as rainwater, can enter the balance bar and become difficult to drain. Prolonged internal water accumulation can affect the performance and service life of the balance bar. Utility Model Content

[0048] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0049] Example 1

[0050] This embodiment relates to a balancing rod, which facilitates the smooth discharge of accumulated water entering the balancing rod; an exemplary structure thereof is as follows Figure 1 、 Figure 2 and Figure 3 shown.

[0051] Generally speaking, the balance pole comprises a first connecting base 1, a second connecting base 7, a retractable connecting rod unit connected between the first and second connecting bases 1 and 7, and a first sleeve 2 and a second sleeve 6 respectively inserted into the first and second connecting bases 1 and 7. The first and second sleeves 2 and 6 are relatively movably connected together, the connecting rod unit is located within the inner cavity formed by the first and second sleeves 2 and 6, and a compressed spring 3 is disposed between the first and second sleeves 2 and 6. Furthermore, a drainage channel is provided between the first connecting base 1 and the first sleeve 2, connecting the outer environment to the inner cavity.

[0052] It should be noted that the stabilizer bar of the present invention is primarily used to provide elastic support between two relatively moving components. It is most commonly installed between a vehicle's tailgate and body, with the first connecting base 1 being used to connect to the tailgate, and the second connecting base 7 being used to connect to the body. Of course, the stabilizer bar of the present invention is not limited to use on vehicle tailgates.

[0053] Based on the above-mentioned overall design concept, the technical solution of the present invention can adopt a variety of different specific implementation structures, forms or configuration sequences. For example, the above-mentioned first sleeve 2 and second sleeve 6 are connected in a sleeve manner, and the two can slide relative to each other in the axial direction. The first sleeve 2 can be sleeved on the outside of the second sleeve 6, or the second sleeve 6 can be sleeved on the outside of the first sleeve 2; the specific setting order and installation method of the first connecting seat 1, the first sleeve 2, the second sleeve 6, the second connecting seat 7 and the connecting rod unit can also be flexibly adjusted. For the parts required for the implementation of the overall solution but not involved in the above-mentioned overall setting, reasonable and flexible design can be made by referring to the mature setting means in the field, the actual situation during implementation, etc. The specific implementation scheme described below in this embodiment is only a better one of the many schemes that can be formed by the above-mentioned various combinations and variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many schemes that can be formed by the above-mentioned various specific forms and variations, as well as the specific implementation scheme of this embodiment, are all within the scope of protection of the present invention.

[0054] Specifically, if Figures 4 to 9 As shown, the first connecting base 1 of this embodiment is provided with a first inserting post 102, which is plugged into the first sleeve 2. The top of the first inserting post 102 is provided with a first threaded hole 105 for connecting the connecting rod unit; the end of the connecting rod 4 described below is threaded into the first threaded hole 105.

[0055] Meanwhile, the second connection base 7 is provided with a second plug-in post 703, which is plugged into the second sleeve 6. The top of the second plug-in post 703 is provided with a second threaded hole 702 for connecting the connecting rod unit. The external thread 802 at the end of the sliding sleeve 8 described below is threadedly connected to the second threaded hole 702.

[0056] By providing a first insertion post 102 on the first connecting seat 1 and a second insertion post 703 on the second connecting seat 7, the first sleeve 2 and the second sleeve 6 are respectively inserted and matched, thereby conveniently assembling the first sleeve 2, the second sleeve 6, the first connecting seat 1 and the second connecting seat 7. The first sleeve 2 and the second sleeve 6 are pressed against the corresponding connecting seats by the spring 3. The connecting rod unit and the connecting seat are connected by a screw connection, which has the characteristics of reliable connection performance and convenient assembly operation.

[0057] Of course, the first connecting base 1 has a first ball socket 101 at the other end of the first connecting base 1, opposite to the end where the first threaded hole 105 is provided. This first ball socket 101 can be hinged to the ball hinge structure on the vehicle's tailgate. Similarly, the second connecting base 7 has a second ball socket 701 at the other end of the second connecting base 7, opposite to the end where the second insertion post 703 is provided. This second ball socket 701 can be hinged to the ball hinge structure on the vehicle body.

[0058] Regarding the arrangement of the drainage channel, there are of course a variety of different structural solutions to choose from. In this embodiment, Figure 7 and Figure 8 As shown, a drainage groove 104 is provided at the top edge of the first plug-in column 102, a drainage groove 103 is provided on the side wall of the first plug-in column 102, and a drainage hole 203 is provided on the first sleeve 2. The drainage groove 104, drainage groove 103, and drainage hole 203 are sequentially connected to form a drainage channel. Obviously, the end of the first sleeve 2 that is used for plugging and mating with the first plug-in column 102 can be referred to as the plug-in tube 204. The drainage hole 203 should be provided on the plug-in tube 204 and correspond to the drainage groove 103 on the side wall of the first plug-in column 102. The specific number of the drainage grooves 104, drainage grooves 103, and drainage holes 203 can be flexibly selected; preferably, multiple drainage channels can be evenly spaced along the circumference of the first sleeve 2. It should be noted that the use of multiple groove structures to form a drainage channel can avoid the situation where direct holes in the first connector 1 or the first sleeve 2 would cause direct leakage of spring grease.

[0059] A leakage groove 104 is set on the top of the first plug-in column 102 of the first connecting seat 1, and a drainage groove 103 is set on the side wall of the first plug-in column 102 accordingly. At the same time, a drainage hole 203 is opened on the end side wall of the first sleeve 2 corresponding to the drainage groove 103. After the assembly of the balance bar is completed, a drainage channel that reliably conducts to the outside world can be formed. When the tailgate of the car is closed, the first connecting seat 1 is located at the bottom of the entire balance bar. If there is water in the inner cavity, it can be conveniently discharged to the outside of the balance bar through the drainage channel at the bottom.

[0060] In order to provide a suitable point of force for the action of the spring 3 on the first sleeve 2 and the second sleeve 6, there are of course a variety of structural solutions. Figure 5 As shown, a first stopper 202 is formed on the inner wall of one end of the first sleeve 2, which is used to insert into the first connecting seat 1. This first stopper 202 is located at the junction of the aforementioned insertion tube 204 and the main body of the first sleeve 2. The first stopper 202 abuts and connects with the top of the first insertion post 102. A spring 3 is located within the inner cavity and sleeved onto the exterior of the connecting rod unit. The end of the spring 3 closest to the first connecting seat 1 abuts against the side of the first stopper 202 facing away from the first insertion post 102.

[0061] By providing a first limiting boss 202 on the inner wall of the end of the first sleeve 2, the two sides of the first limiting boss 202 can respectively abut and cooperate with the first insertion column 102 and the spring 3, thereby limiting the first connecting seat 1 and the spring 3. The spring 3 is disposed within the inner cavities of the first sleeve 2 and the second sleeve 6, which not only facilitates the elastic support of the spring 3 between the first sleeve 2 and the second sleeve 6, but also effectively achieves a concealed arrangement of the spring 3, providing good protection for the spring 3 through the first sleeve 2 and the second sleeve 6.

[0062] like Figure 10 and Figure 11 As shown, a second limiting boss 601 is formed on the inner wall of the middle part of the second sleeve 6 of this embodiment, and a through hole 602 for the connecting rod unit to pass through is formed at the second limiting boss 601, and one end of the spring 3 close to the second connecting seat 7 acts on the second limiting boss 601.

[0063] A second limiting boss 601 is provided in the middle of the second sleeve 6 to form an abutment limit for the other end of the spring 3, providing a well-positioned point of force for the spring 3's elastic support on the second sleeve 6. A through-hole 602 reserved in the second limiting boss 601 not only allows the connecting rod unit to pass through, but also radially limits the connecting rod unit, allowing it to smoothly complete its telescopic movement within the inner cavity. Furthermore, to enhance the structural stability of the second limiting boss 601, multiple reinforcing ribs 603 can be provided between the second limiting boss 601 and the inner wall of the second sleeve 6, providing a more stable abutment point for the spring 3.

[0064] In addition, in the balance bar of this embodiment, a spring limiting tube 5 is also provided. Figure 12 、 Figure 13 Combined with Figure 2 As shown, a spring stop tube 5 is disposed within the inner cavity between the second stop boss 601 and the first stop boss 202, and is sleeved onto the exterior of the connecting rod unit. The aforementioned spring 3 is sleeved onto the exterior of the spring stop tube 5. The end of the spring stop tube 5, which is located near the second stop boss 601, is provided with an end flange 501. This end flange 501 abuts against the second stop boss 601, and the end of the spring 3, which is located near the second connecting seat 7, abuts against this end flange 501.

[0065] As can be seen, a spring stopper 5 is configured for the spring 3. The tube body 502 of the spring stopper 5 can form a support and limit for the spring 3 inside the spring 3, thereby confining the spring 3 between the spring stopper 5 and the inner wall of the inner cavity for expansion and contraction, preventing the spring 3 from twisting and deforming during compression, thereby ensuring that the balance bar has more stable elastic support performance. An end flange 501 is provided at the end of the spring stopper 5, which can be pressed against the second stopper boss 601 of the second sleeve 6 by the spring 3, so that the spring stopper 5 moves synchronously with the second sleeve 6, preventing the spring stopper 5 from moving arbitrarily within the inner cavity.

[0066] Based on the above arrangement, preferably, the second sleeve 6 can be sleeved onto the exterior of the first sleeve 2, and first sliding ribs 201 can be provided on the outer wall of the first sleeve 2 to slidably engage with the second sleeve 6. Second sliding ribs 503 can also be provided on the inner wall of the spring stop tube 5 to slidably engage with the connecting rod unit. Providing sliding ribs on the first sleeve 2 and the spring stop tube 5 reduces the contact area between the relatively moving walls, thereby lowering friction between the relatively sliding components and facilitating smoother extension and retraction of the balance bar.

[0067] As for the specific arrangement of the connecting rod unit, there are of course a variety of different structural solutions to choose from; for example, the structure of the gas spring can still be used. However, in this embodiment, Figure 2 、 Figure 3 and Figure 12 As shown, the connecting rod unit of this embodiment includes a sliding sleeve 8 connected to the second connecting seat 7, a limiting sliding sleeve 9 slidably disposed in a sliding cavity 80 within the sliding sleeve 8, and a connecting rod 4 with its ends respectively connected to the first connecting seat 1 and the limiting sliding sleeve 9. The other end of the sliding sleeve 8, opposite to the end connected to the second connecting seat 7, is provided with a retaining protrusion 800 for retaining the limiting sliding sleeve 9 in the sliding cavity 80.

[0068] The connecting rod unit utilizes a sliding sleeve 8, connecting rod 4, and a limiting sleeve 9, resulting in a simple structure and easy assembly. While maintaining excellent telescopic performance, it also creates a secure connection between the first and second connecting seats 1, 7, and limits the maximum extension length of the balance bar. A retaining protrusion 800 is extruded into the wall of the sliding sleeve 8, facilitating its integrated molding and effectively confining the limiting sleeve 9 within the sliding cavity 80, preventing the connecting rod 4 from completely dislodging.

[0069] At the same time, a plurality of vent holes 801 can be provided on the sliding sleeve 8 on the side of the retaining protrusion 800 near the first connecting seat 1. By providing the vent holes 801 on the wall of the sliding sleeve 8, when the limiting sleeve 9 slides in the sliding cavity 80, the gas in and out of the sliding cavity 80 from the retaining protrusion 800 can be more conveniently connected to the inner cavity of the first sleeve 2 through the vent holes 801, and then connected to the outside world through the drainage channel; thus, the occurrence of air suffocation inside the balance bar is prevented, and the influence of changes in the external temperature on the elastic support performance of the balance bar is avoided. Moreover, when water enters the sliding cavity 80, the accumulated water in the sliding cavity 80 can be easily discharged to the outside world through the gap between the retaining protrusion 800 and the connecting rod 4, the vent holes 801, the inner cavity, and the drainage channel.

[0070] To sum up, the balance bar of this embodiment forms an elastic support for the tailgate by hingedly connecting the first connecting seat 1 to the tailgate of the car and hingedly connecting the second connecting seat 7 to the car body; based on the plug-in fit between the first connecting seat 1 and the first sleeve 2, and the second sleeve 6 and the second connecting seat 7, a drainage channel is set between the first connecting seat 1 and the first sleeve 2. When water abnormally enters the inner cavity of the first sleeve 2 and the second sleeve 6 to form accumulated water, the accumulated water can be discharged to the outside of the balance bar through the drainage channel, thereby improving the performance stability and durability of the balance bar.

[0071] Example 2

[0072] This embodiment relates to a vehicle, the tailgate of which adopts the balance bar provided in the first embodiment.

[0073] If a vehicle is equipped with a tailgate, especially an electric tailgate, a balance bar must be provided between the door body and the vehicle body to assist the electric actuator in opening and closing the tailgate.

[0074] With the balancing bar of the present invention, the first connecting seat 1 is used to connect to the tailgate of the car, and the second connecting seat 7 is used to connect to the car body. The entire balancing bar can assist the electric actuator to form a good elastic support for the tailgate.

[0075] The spring 3, located within the inner cavity enclosed by the first and second sleeves 2 and 6, is in a compressed state, with its ends applying elastic support forces to the first and second sleeves 2 and 6, respectively, thereby tightly abutting the first sleeve 2 against the first connection seat 1, and the second sleeve 6 against the second connection seat 7. By providing a drainage channel between the first connection seat 1 and the first sleeve 2, if water accidentally enters the balance pole, the accumulated water can be drained to the outside of the balance pole through the drainage channel.

[0076] Moreover, the balance bar of the present invention has a simple overall structure, fewer parts, is easy to assemble, and has reliable performance; it has certain cost advantages.

[0077] At the same time, the limiting sleeve 9 can be slidably set in the sliding cavity 80, and there is no need to use an interference sealing structure between the limiting sleeve 9 and the inner wall of the sliding cavity 80, that is, the sliding cavities 80 on both sides of the limiting sleeve 9 can conduct gas, which can avoid the influence of the external temperature on the performance of the balance bar due to air holding in the sliding cavity 80.

[0078] The above description is merely a preferred embodiment of the present invention. The detailed configuration explanations, specific structural configuration examples, and assembly connection descriptions are provided for the purpose of providing sufficient disclosure to enable those skilled in the art to better implement the present invention. They are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
