Description

Technical Field

[0001] The present application belongs to the technical field of balancing vehicles, and specifically relates to a gravity balancing vehicle. Background Art

[0002] Traditional traveling equipment usually includes two-wheelers, three-wheelers and four-wheelers. Two-wheelers including motorcycles and electric bicycles are small and compact, but they are poorly sealed and are not suitable for high and low temperatures, rainy or snowy weather. Small three-wheelers or four-wheelers are easy to set up with closed compartments, and have good applicability in high and low temperatures, rainy and snowy weather, but their steering at medium and high speeds can easily cause the center of gravity of the vehicle to shift, causing the vehicle to roll over and lack safety. Widening the vehicle to lower the center of gravity will increase the size of the vehicle, affecting the vehicle's agility, limiting its applicable occasions and affecting the user experience.

[0003] In order to solve this technical problem, a balance vehicle is provided in the prior art, wherein the vehicle body and the chassis are connected by a swing device, and when the vehicle body is turned, the vehicle body swings relative to the chassis through the swing device, thereby reducing the center of gravity offset of the chassis and improving the steering stability of the balance vehicle. However, the prior art has the following problems: since the chassis is set at a lower position, the vehicle body is higher than the chassis, and the swing device is installed on the chassis, the center of gravity of the vehicle body is higher than the swing device, that is, the center of gravity of the vehicle body when the vehicle body swings is located below its center of gravity, and the vehicle body is easily affected by a small disturbance and swings around the center of gravity, thereby deviating from the original position and failing to maintain stability for a long time. Summary of the invention

[0005] The technical solution adopted in this application is:

[0006] A gravity-balancing vehicle comprises a first seat body, a second seat body and a swing mechanism connecting the first seat body and the second seat body, wherein the swing mechanism comprises a first gravity distribution rod and a second gravity distribution rod, wherein the bottom of the first gravity distribution rod is connected to the first seat body, the top of the first gravity distribution rod is provided with a first rotating member so that the first rotating member is higher than the first seat body, the bottom of the second gravity distribution rod is connected to the second seat body, the top of the second gravity distribution rod is provided with a second rotating member so that the second rotating member is higher than the second seat body, and the first seat body can swing relative to the second seat body through the rotational connection between the first rotating member and the second rotating member; and further comprises a first moving member provided at the bottom of the first seat body and a second moving member provided at the bottom of the second seat body, wherein the angle and spacing between the first moving member and the second gravity distribution rod increase synchronously with the increase of the swing amplitude of the first seat body relative to the second seat body. The gravity-balancing vehicle described in the present application also comprises the following additional technical features:

[0007] The first moving member includes a first moving wheel provided on the first base body and a second moving wheel provided on the second base body. There is one first moving wheel located in the middle of the first base body away from the second base body. There are two second moving wheels symmetrically arranged on the left and right sides of the second base body.

[0008] A first driver's seat is provided on the first seat body, and the first driver's seat and the first seat body together constitute a supporting seat, and the center of gravity of the supporting seat is located below the first rotating member. A first steering mechanism is also provided on the first seat body, and the first steering mechanism can control the steering of the first moving wheel, thereby driving the supporting seat to swing relative to the second seat body through the swing mechanism.

[0009] It also includes a second steering mechanism acting on the first movable wheel. A second driver's seat is provided on the second seat body. The second steering mechanism includes a rotating disk located in front of the second driver's seat. The rotating disk can rotate to drive the first movable wheel to rotate left and right.

[0010] The first rotating member is a rotating sleeve, the second rotating member is a rotating rod, the rotating sleeve is sleeved on the rotating rod and can rotate around the rotating rod.

[0011] The rotating rod is provided with a first limiter and a second limiter on both sides of the rotating sleeve in the length direction. The first limiter and the second limiter can stop the rotating sleeve to limit the displacement of the rotating sleeve along the length direction of the rotating rod.

[0012] The connection between the first seat body and the first gravity distribution rod is a first connection point, the connection between the first gravity distribution rod and the first rotating member is a second connection point, and the first gravity distribution rod extends in a vertical direction so that the first connection point and the second connection point are located in the same vertical plane.

[0013] The connection point between the second gravity distribution rod and the second rotating member is a third connection point, and the second connection point and the third connection point are located in the same horizontal plane.

[0014] The distance between the second connection point and the third connection point is L1, the distance between the first connection point and the second connection point is L2, and L1≤0.3L2.

[0015] It also includes a first reinforcing rod, one end of which is fixedly connected to the first gravity distribution rod, and the other end of which extends obliquely in a direction forming an angle with the first gravity distribution rod and is fixedly connected to the first seat body, and / or it also includes a second reinforcing rod, one end of which is fixedly connected to the second gravity distribution rod, and the other end of which extends in a direction forming an angle with the first gravity distribution rod and away from the second rotating member and is fixedly connected to the second seat body.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0017] 1. The gravity balance vehicle of the present application includes a first seat body, a second seat body and a swinging mechanism, and the first seat body can swing relative to the second seat body through the swinging mechanism. Therefore, when the first seat body swings relative to the second seat body, only the center of gravity of the first seat body shifts, and the center of gravity of the second seat body remains stable as a whole, so the overall center of gravity of the balance vehicle tends to be stable; the amplitude of the center of gravity shift of the balance vehicle during the swinging of the first seat body is reduced, which helps to maintain the stability of the balance vehicle; in addition, the balance vehicle of the present application also includes a first gravity distribution rod and a second gravity distribution rod, wherein the second gravity distribution rod is used to raise the height of the second rotating member, so that the second rotating member and the first rotating member that rotates therewith are located above the second seat body, so that the first gravity distribution rod can hang the first seat body below the first rotating member. On the one hand, the center of gravity of the first seat is lowered, so that the center of gravity of the first seat is shorter from the ground. The lower the center of gravity is, the higher the stability of the first seat is, and the probability of imbalance during the swing of the first seat is reduced. On the other hand, since the rotation connection point between the first rotating member and the second rotating member is the center of the swing when the first seat swings, when the first seat swings, the movement trajectory of the center of gravity shift is located below the swing point, and the direction of the gravity acceleration of the first seat during the swing is downward, so that the first seat naturally tends to the balance point below the center of the swing during the swing. In this case, the first seat has higher stability when it swings, and there is no rollover phenomenon caused by the displacement of the center of gravity of the first seat.

[0018] When the first seat body is not acted upon by an external force, it can remain stable under the support of the first movable member. When it is swung by an external force, since the swing point is located above it, the swing force along the swing trajectory direction of the first seat body will be partially offset by the gravity of the first seat body during the swinging process of the first seat body. As the swing force is gradually reduced, the swing amplitude of the first seat body will gradually decrease until it is stable. Therefore, when the first seat body is swung by an external force, the driver does not need to apply additional force to reset it. It can gradually offset the swing force and maintain stability under the action of its own gravity. On this basis, since the angle and spacing between the first movable member and the second gravity distribution rod increase synchronously with the increase in the swing amplitude of the first seat body relative to the second seat body, when the balancing car needs to be turned, the user can deflect the first seat body in the direction to be turned by pressing it down toward the side to be turned. At this time, on the one hand, the angle between the first movable member and the second gravity distribution rod increases with the deflection of the first seat body, and at the same time, the lateral distance between the contact point between the first movable member and the lower moving surface and the second gravity distribution rod gradually increases. At this time, the first seat body and the swing mechanism are regarded as a whole, and this whole is supported on the moving surface and the second seat body through the first movable member and the second gravity distribution rod. Due to the misalignment between the first movable member and the second gravity distribution rod, the lateral distance between the front and rear supporting points of the first seat body and the swing mechanism is increased, and the supporting stability of the first seat body and the swing mechanism on the second seat body and the moving surface is enhanced, thereby improving the stability of the balance vehicle when turning, and greatly reducing the probability of the balance vehicle rolling over when turning.

[0019] 2. As a preferred embodiment of the present application, there is one first moving wheel and it is located in the middle of the first seat body, and the second moving wheels are distributed on both sides of the second seat body, so that the gravity balance vehicle forms a three-point stable support structure under the joint support of the first moving wheel and the second moving wheel, which helps to improve the driving stability of the gravity balance vehicle; on this basis, the first moving wheel is arranged in the middle of the first seat body. When the first moving wheel turns, the angle between it and the ground will change, and drive the first seat body to swing, so that the turning of the balance vehicle is smoother.

[0020] 3. As a preferred embodiment of the present application, the support seat formed by the first seat body and the first driving seat provides a seat for the driver and the passenger, and the center of gravity of the support seat is located below the first rotating member, so that the support seat is suspended below the rotation connection point between the first rotating member and the second rotating member. When the support seat swings, the component of its swing force in the vertical direction will be offset by gravity. Therefore, when the balance vehicle is turning, the support seat first swings under the driving action of the first moving wheel. When the balance vehicle needs to be reset after turning, the gravity of the support seat will partially offset the swing force during its swing, so that the support seat can be reset from the deflected position after the swing to the initial position, thereby improving the driving stability.

[0021] 4. As a preferred embodiment of the present application, the first rotating member is set as a rotating sleeve and the second rotating member is set as a rotating rod, which can effectively ensure the rotation smoothness of the first rotating member and the second rotating member, thereby improving the smoothness of the swinging process of the first seat body and reducing the probability of the first seat body swinging being restricted due to the jamming of the first rotating member and the second rotating member; in addition, the gravity of the first seat body and the first gravity distribution rod is completely borne by the first rotating member and the second rotating member, and the contact area between the rotating sleeve and the rotating rod is large, so the gravity of the first seat body and the first gravity distribution rod can be evenly borne, reducing the possibility of stress concentration at the connection between the first rotating member and the second rotating member, which helps to maintain the service life of the gravity balance system; furthermore, the second rotating member is set as a rotating rod, and the relative position between the connection point with the rotating sleeve and the second seat body can be controlled by adjusting the length of the rotating rod, which is convenient for effectively adjusting the connection point according to the structural design requirements.

[0022] 5. As a preferred embodiment of the present application, since the relative rotational force between the rotating sleeve and the rotating rod is derived from the swinging of the first seat body, the swinging process of the first seat body may be affected by external force and the swinging force may be deflected, which in turn causes the rotating sleeve to be affected by the eccentric force and have a tendency to slide along the axial direction of the rotating rod; by setting the first limiter and the second limiter, the radial movement of the rotating sleeve along the rotating rod can be limited, so that the rotating sleeve is stably placed between the first limiter and the second limiter, thereby ensuring the stability of the relative position relationship between the first seat body and the second seat body. This avoids the rotating sleeve sliding away from the second seat body to escape from the rotating rod due to uneven force applied by the first seat body, or the rotating sleeve sliding toward the second seat body to cause the first seat body and the second seat body to contact and collide, which helps to maintain the operational stability of the gravity balance system.

[0023] 6. As a preferred embodiment of the present application, the first connection point and the second connection point are arranged to be located in the same vertical plane, so that when the first gravity distribution rod swings synchronously with the swing of the first seat body, the direction of its gravity acceleration and the direction of gravity are both located within the vertical plane, and the direction of the force of the first gravity distribution rod acting on the first rotating member and the second rotating member is both located within the vertical plane; the force stability of the first rotating member and the second rotating member is improved, and the two can undergo relatively stable relative rotation under the action of the force, which reduces the bearing pressure of the first rotating member and the second rotating member while providing a guarantee for the swinging stability of the first seat body.

[0024] 7. As a preferred embodiment of the present application, when the first seat body makes a swinging motion with the first connection point as the swing center, its own gravity and the swinging force generated during the swinging process will be transmitted to the second gravity distribution rod through the first rotating member and the second rotating member, and the second connection point is set to be located in the same horizontal plane as the third connection point, so that the force generated on the first connection point during the swinging process of the first seat body can be better transmitted to the second gravity distribution rod through the second connection point, thereby enabling the second seat body to play a better bearing role on the swinging mechanism and the first seat body, which helps to improve the stability of the gravity balance system.

[0060] Embodiment 1:

[0061] like Figures 1 to 8As shown, a gravity balancing vehicle comprises a first seat body 1, a second seat body 2 and a swinging mechanism connecting the first seat body 1 and the second seat body 2, the swinging mechanism comprises a first gravity distribution rod 3 and a second gravity distribution rod 4, the bottom of the first gravity distribution rod 3 is connected to the first seat body 1, the top of the first gravity distribution rod 3 is provided with a first rotating member, so that the first rotating member is higher than the first seat body 1, the bottom of the second gravity distribution rod 4 is connected to the second seat body 2, the top of the second gravity distribution rod 4 is provided with a second rotating member, so that the second rotating member is higher than the second seat body 2, and the first seat body 1 can swing relative to the second seat body 2 through the rotational connection between the first rotating member and the second rotating member; it also comprises a first moving member 7 arranged at the bottom of the first seat body 1 and a second moving member 8 arranged at the bottom of the second seat body 2, the angle and spacing between the first moving member 7 and the second gravity distribution rod 4 increase synchronously with the increase of the swing amplitude of the first seat body 1 relative to the second seat body 2.

[0062] The gravity balance vehicle of the application includes a first seat body 1, a second seat body 2 and a swinging mechanism. The first seat body 1 can swing relative to the second seat body 2 through the swinging mechanism. Therefore, when the first seat body 1 swings relative to the second seat body 2, only the center of gravity of the first seat body 1 is shifted, and the center of gravity of the second seat body 2 remains stable as a whole. Therefore, the overall center of gravity of the balance vehicle tends to be stable; the amplitude of the center of gravity shift of the balance vehicle during the swinging of the first seat body 1 is reduced, which helps to maintain the stability of the balance vehicle; in addition, the balance vehicle of the present application also includes a first gravity distribution rod 3 and a second gravity distribution rod 4, wherein the second gravity distribution rod 4 is used to raise the height of the second rotating member, so that the second rotating member and the first rotating member that rotates therewith are located above the second seat body 2, so that the first gravity distribution rod 3 can hang the first seat body 1 under the first rotating member. On the one hand, the center of gravity of the first seat body 1 is lowered, so that the center of gravity of the first seat body 1 is shorter from the ground. The lower the center of gravity is, the higher the stability of the first seat body 1 is, and the probability of imbalance during the swing of the first seat body 1 is reduced. On the other hand, since the rotation connection point between the first rotating member and the second rotating member is the center of the swing when the first seat body 1 swings, when the first seat body 1 swings, the movement trajectory of the center of gravity shift is located below the swing point, and the direction of the gravity acceleration of the first seat body 1 during the swing is downward, so that the first seat body 1 naturally tends to the balance point below the center of the swing during the swing. In this case, the first seat body 1 has a higher stability when it swings, and there is no rollover phenomenon caused by the displacement of the center of gravity of the first seat body 1.

[0063] When the first seat body 1 is not acted upon by external forces, it can remain stable under the support of the first moving member 7. When it is swung by external forces, since the swing point is located above it, the swing force along the swing trajectory of the first seat body 1 will be partially offset by the gravity of the first seat body 1 during the swinging process of the first seat body 1. As the swing force is gradually reduced, the swing amplitude of the first seat body 1 will gradually decrease until it is stable. Therefore, when the first seat body 1 is swung by external forces, the driver does not need to apply additional force to reset it. It can gradually offset the swing force and maintain stability under the action of its own gravity.

[0064] On this basis, since the angle and spacing between the first moving member 7 and the second gravity distribution rod 4 increase synchronously with the increase of the swing amplitude of the first base body 1 relative to the second base body 2, when the balance car needs to be turned, the user can deflect the first base body 1 toward the side to be turned by pressing down the first base body 1. At this time, the angle between the first moving member 7 and the second gravity distribution rod 4 increases with the deflection of the first base body 1, and the lateral distance between the contact point between the first moving member 7 and the lower moving surface and the second gravity distribution rod 4 also gradually increases. The moving surface mentioned here refers to the surface of the object where the balance car is located. For example, if the balance car is on the ground, the moving surface is the ground. At this time, the first base body 1 and the swing mechanism are regarded as a whole, and this whole is supported on the moving surface and the second base body 2 by the first moving member 7 and the second gravity distribution rod 4. Due to the misalignment between the first movable member 7 and the second gravity distribution rod 4, the lateral distance between the two front and rear support points of the first seat body 1 and the swing mechanism is increased, thereby enhancing the support stability of the first seat body 1 and the swing mechanism on the second seat body 2 and the moving surface, thereby improving the stability of the balance vehicle when turning, and greatly reducing the probability of the balance vehicle tipping over when turning. The angle and distance between the first movable member 7 and the second gravity distribution rod 4 mentioned above refer to the angle and distance between the projection of the first movable member 7 toward the second seat body 2 and the second gravity distribution rod 4. Figure 2 , Figure 3 As shown, the balance car is composed of Figure 2 In the straight state, turn in the M direction to Figure 3 When the state is , α1 and D1 refer to the angle and distance between the first moving member 7 and the second gravity distribution rod 4 when the balancing vehicle turns to the M direction; Figure 2 , Figure 4 As shown, the balance car is composed of Figure 2 The straight state in the N direction is rotated to Figure 4 , α2 and D2 refer to the angle and distance between the first moving member 7 and the second gravity distribution rod 4 when the balancing vehicle turns to the N direction.

[0065] As a preferred embodiment of the present application, Figure 2As shown, the first movable member 7 includes a first movable wheel provided on the first base body 1 and a second movable wheel provided on the second base body 2. There is one first movable wheel and it is located in the middle of the first base body 1 away from the second base body 2. There are two second movable wheels and they are symmetrically arranged on the left and right sides of the second base body 2.

[0066] There is one first moving wheel located in the middle of the first seat body 1, and the second moving wheels are distributed on both sides of the second seat body 2, so that the gravity balance vehicle forms a three-point stable support structure under the joint support of the first moving wheel and the second moving wheel, which helps to improve the driving stability of the gravity balance vehicle; on this basis, the first moving wheel is set in the middle of the first seat body 1. When the first moving wheel turns, the angle between it and the ground will change, and drive the first seat body 1 to swing, so that the turning of the balance vehicle is smoother.

[0067] This embodiment does not limit the load position of the driver, and can adopt any of the following examples:

[0068] Example 1: Figure 5 As shown, a first driver's seat 9 is provided on the first seat body 1, and the first driver's seat 9 and the first seat body 1 together constitute a supporting seat 10. The center of gravity of the supporting seat 10 is located below the first rotating member. A first steering mechanism is also provided on the first seat body 1. The first steering mechanism can control the steering of the first movable wheel, thereby driving the first seat body 1 to swing relative to the second seat body 2 through the swing mechanism.

[0069] The support seat 10 formed by the first seat body 1 and the first driving seat 9 provides a seat for the driver and the passengers, and the center of gravity of the support seat 10 is located below the first rotating member, so that the support seat 10 is suspended below the rotation connection point of the first rotating member and the second rotating member. When the support seat 10 swings, the component of its swing force in the vertical direction will be offset by gravity. Therefore, when the balancing vehicle is turning, the support seat 10 first swings under the driving action of the first moving wheel. When the balancing vehicle ends the turning and needs to be reset, the gravity of the support seat 10 will partially offset the swing force during its swing, so that the support seat 10 can be reset from the deflected position after the swing to the initial position, thereby improving the driving stability.

[0070] Example 2: If Figure 6 As shown, it also includes a second steering mechanism acting on the first moving wheel. A second driver's seat 110 is provided on the second seat body 2. The second steering mechanism includes a rotating disk located in front of the second driver's seat 110. The rotating disk can rotate to drive the first moving wheel to rotate left and right.

[0071] A second driver's seat 110 is arranged on the second seat body 2 to provide a seating position for the driver and passengers. The first seat body 1 only plays the function of swinging to drive the second seat body 2 to turn, which helps to maintain a low center of gravity of the first seat body 1. Since the center of gravity of the first seat body 1 is relatively low, during the process of swinging to drive the vehicle to turn, the center of gravity of the first seat body 1 is always located below the connection point between the first rotating part and the second rotating part, which greatly reduces the probability of the first seat body 1 being offset and rolling over, thereby greatly improving the steering stability of the balancing vehicle.

[0072] As a preferred embodiment of the present application, Figures 1 to 6 As shown, the first rotating member is a rotating sleeve 6, and the second rotating member is a rotating rod 5. The rotating sleeve 6 is sleeved on the rotating rod 5 and can rotate around the rotating rod 5. The first rotating member is set as the rotating sleeve 6, and the second rotating member is set as the rotating rod 5, which can effectively ensure the smoothness of the rotation of the first rotating member and the second rotating member, thereby improving the smoothness of the swinging process of the first seat body 1 and reducing the probability of the first seat body 1 swinging restricted due to the jamming of the first rotating member and the second rotating member; in addition, the gravity of the first seat body 1 and the first gravity distribution rod 3 is completely borne by the first rotating member and the second rotating member, and the contact area between the rotating sleeve 6 and the rotating rod 5 is large, so the gravity of the first seat body 1 and the first gravity distribution rod 3 can be evenly borne, reducing the possibility of stress concentration at the connection between the first rotating member and the second rotating member, which is helpful to maintain the service life of the gravity balance system; furthermore, the second rotating member is set as the rotating rod 5, and the relative position between the connection point with the rotating sleeve 6 and the second seat body 2 can be controlled by adjusting the length of the rotating rod 5, so that the connection point can be effectively adjusted according to the structural design requirements.

[0073] Preferably, if Figure 5 , Figure 6As shown, the rotating rod 5 is provided with a first stopper 51 and a second stopper 52 on both sides of the length direction of the rotating sleeve 6. The first stopper 51 and the second stopper 52 can stop the rotating sleeve 6 to limit the displacement of the rotating sleeve 6 along the length direction of the rotating rod 5. Since the relative rotational force between the rotating sleeve 6 and the rotating rod 5 comes from the swinging of the first seat body 1, the swinging process of the first seat body 1 may be affected by an external force and cause the swinging force to be offset, which in turn causes the rotating sleeve 6 to slide along the axial direction of the rotating rod 5 under the action of the eccentric force; by providing the first stopper 51 and the second stopper 52, the radial movement of the rotating sleeve 6 along the rotating rod 5 can be limited, so that the rotating sleeve 6 is stably placed between the first stopper 51 and the second stopper 52, thereby ensuring the stability of the relative position relationship between the first seat body 1 and the second seat body 2. This avoids the rotating sleeve 6 sliding away from the second seat body 2 to escape from the rotating rod 5 due to uneven force applied by the first seat body 1 to the rotating sleeve 6, or the rotating sleeve 6 sliding toward the second seat body 2 to cause contact and collision between the first seat body 1 and the second seat body 2, which helps to maintain the operating stability of the gravity balance system.

[0074] As a preferred embodiment of the present application, Figure 7 As shown, the connection point between the first seat body 1 and the first gravity distribution rod 3 is the first connection point 120, and the connection point between the first gravity distribution rod 3 and the first rotating member is the second connection point 130. The first gravity distribution rod 3 extends in the vertical direction so that the first connection point 120 and the second connection point 130 are located in the same vertical plane. The first connection point 120 and the second connection point 130 are set to be located in the same vertical plane, so that when the first gravity distribution rod 3 swings synchronously with the swing of the first seat body 1, its gravity acceleration direction and gravity direction are both located within the vertical plane, and the direction of the force of the first gravity distribution rod 3 on the first rotating member and the second rotating member is both located within the vertical plane; the force stability of the first rotating member and the second rotating member is improved, and the two can rotate relatively stably under the action of the force, which reduces the bearing pressure of the first rotating member and the second rotating member while providing a guarantee for the swing stability of the first seat body 1.

[0075] Preferably, if Figure 7As shown, the connection point between the second gravity distribution rod 4 and the second rotating member is the third connection point 140, and the second connection point 130 and the third connection point 140 are located in the same horizontal plane. When the first seat body 1 performs a swinging motion with the first connection point 120 as the swing center, its own gravity and the swinging force generated during the swinging process will be transmitted to the second gravity distribution rod 4 through the first rotating member and the second rotating member. The second connection point 130 is set to be located in the same horizontal plane as the third connection point 140, so that the force generated by the first seat body 1 on the first connection point 120 during the swinging process can be better transmitted to the second gravity distribution rod 4 through the second connection point 130, and then the second seat body 2 can play a better bearing role on the swing mechanism and the first seat body 1, which helps to improve the stability of the gravity balance system.

[0076] Furthermore, if Figure 7 As shown, the distance between the second connection point and the third connection point is L1, the distance between the first connection point and the second connection point is L2, and L1≤0.3L2. Since the gravity of the first seat body 1, the first gravity distribution rod 3 and the first rotating member is applied to the second rotating member and transmitted to the second gravity distribution rod 4 through the second rotating member, higher requirements are placed on the structural strength of the second gravity distribution rod 4 and the second rotating member. By setting L1≤0.3L2, the first seat body 1 has sufficient clearance with the second seat body 2 to maintain the normal swinging requirement of the first seat body 1, and the cantilever length of the second rotating member is reduced as much as possible, which helps to reduce the bearing pressure of the second gravity distribution rod 4 and improve the structural stability of the gravity balance system.

[0077] As a preferred embodiment of the present application, Figure 6 As shown, the first reinforcing rod 150 is also included, one end of which is fixedly connected to the first gravity distribution rod 3, and the other end of which extends obliquely along the angle direction with the first gravity distribution rod 3 and is fixedly connected to the first seat body 1. Since the gravity of the first seat body 1 is borne by the first moving member 7 and the first gravity distribution rod 3, by providing the first reinforcing rod 150, another transmission channel is provided for the gravity and the swing force of the swing seat, which reduces the possibility of stress concentration at the connection between the first seat body 1 and the first gravity distribution rod 3, and helps to improve the overall structural strength of the swing mechanism.

[0078] Preferably, if Figure 5As shown, the second reinforcing rod 160 is also included, one end of which is fixedly connected to the second gravity distribution rod 4, and the other end of which extends in a direction that is angled with the first gravity distribution rod 3 and away from the second rotating member and is fixedly connected to the second seat body 2. Since the gravity of the swing seat and the swing mechanism is jointly borne by the first moving member 7 and the second gravity distribution rod 4, a higher load-bearing requirement is imposed on the second gravity distribution rod 4. By providing the second reinforcing rod 160, the second reinforcing rod 160, the second gravity distribution rod 4 and the first moving member 7 jointly bear the load-bearing function of the first seat body 1 and the swing mechanism, which helps to reduce the load-bearing pressure of the second gravity distribution rod 4 and ensure the structural strength of the second gravity distribution rod 4.

[0079] The present application does not limit the number and form of the first gravity distribution rod. The number of the first gravity distribution rod and the second gravity distribution rod can be one, or the number of the first gravity distribution rod and the second gravity distribution rod can be two. Figure 1 There are multiple first gravity distribution rods 3 shown, and the multiple first gravity distribution rods 3 are arranged to converge at an angle; or there are multiple second gravity distribution rods.
