TECHNICAL FIELD
[0001] The utility model relates to air conditioning technical field especially is related to a sliding door drive mechanism, sliding door and air conditioner. BACKGROUND
[0002] With the demand of people for high quality life, air conditioner gradually becomes the indispensable household electrical appliances. For cabinet type air conditioner, usually design sliding door at air outlet, its main function is as follows: 1) when air conditioner is closed, sliding door removes the front of air outlet, closes air outlet, prevents cockroaches or dust and other foreign matters from entering air conditioner interior through air outlet; 2) sliding door effectively shields air outlet internal structure when closing, greatly improves appearance feeling. Based on above function description, design sliding door at air outlet is the current mainstream, and is the future development trend.
[0003] In energy saving and comfort, people put forward higher requirements to air conditioner. By increasing inlet and outlet air area, it can achieve greater improvement effect, which means that the size and weight of sliding door will be further increased, and the abnormal sound and movement stability generated thereby become problems to be solved.
[0004] In life, we often need to move some articles, when we push articles on the ground, often produce harsh sound, let people feel very uncomfortable. When pushing on relatively smooth ground, the sound will be much smaller, when the weight of articles is lighter, the sound produced will also be reduced synchronously. Conversely, when the weight of articles is heavy and the ground is relatively rough, the sound will be very large. When we use the roller to carry articles, often no sound is produced. Therefore, the size of the sound produced is related to the weight of articles, the roughness of the ground and the moving way of articles. The sound produced by rolling is far less than that produced by sliding.
[0005] As shown in Figure 1 , in order to avoid the noise of large weight sliding door when sliding, the ball is installed on the sliding block assembly, the gravity of sliding door is transmitted to the ball, drive box and finally to the ground through the sliding block assembly. When the sliding door needs to move left and right, the driving device drives the sliding block assembly to move, at this time the ball rolls on the bearing plane of the drive box. But because the gravity of sliding door is large, the ball cannot roll in actual assembly, its movement mode is sliding. In the sliding mode, in order to make the movement process not produce abnormal sound, the roughness of contact surface must be reduced, therefore the flatness requirement of sliding block assembly and drive box track surface is very high. It is difficult to achieve in actual production or needs to pay a large cost.
[0006] As shown in Figure 2 , in order to overcome the above problems, the ball is changed to the roller, which can ensure the rolling performance of itself to a certain extent under the condition of increasing the weight of sliding door. But the flatness requirement of parts is still very high, otherwise the sliding abnormal sound problem will also appear. Utility model content

[0055] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0056] like Figure 3-Figure 7The utility model provides a sliding door drive mechanism, including slider assembly 1, helical gear 2, drive box 3, wherein,
[0057] Slider assembly 1 is connected with sliding door 13 to drive sliding door 13 to move.
[0058] Helical gear 2 is rotatably arranged on slider assembly 1.
[0059] Drive box 3 is provided with sliding rail 4 to form the moving route of sliding door 13.
[0060] Helical gear 2 is rollingly connected with sliding rail 4.
[0061] The sliding door drive mechanism of the utility model changes the ball or the roller into the helical gear 2, the tooth thickness 8 of the helical gear 2 can increase with the increase of the weight of the door plate, reduces the pressure intensity, reduces the abrasion problem of the bearing track surface of the drive box 3, reduces the abnormal sound and the jamming of movement, when the weight of the sliding door 13 part increases, the contact area is increased, the abrasion problem of the track of the drive box 3 due to the high pressure is solved.
[0062] In order to make more stable when moving, ensure rolling connection, the bearing surface of sliding rail 4 is provided with the helical tooth structure 5, and the helical tooth structure 5 is compatible with the specification of helical gear 2.
[0063] The bearing track surface of drive box 3 is designed as a helical surface, which is matched with the helical gear 2, that is, the helical tooth structure 5 is engaged with the helical gear 2, to ensure that the two are rolling, and the helical tooth characteristics are transitional engagement, to make the movement more stable and solve the abnormal sound and jamming problem in the sliding process.
[0064] In order to prevent the mutual dead top of helical gear 2 and helical tooth structure 5 from causing the jamming of the movement of sliding door 13, in the embodiment, the tooth top of helical tooth structure 5 and the tooth bottom of helical gear 2 are gap assembly structures, and the fitting gap 15 can be 0.3-0.5mm.
[0065] In order to ensure that the slider assembly 1 or the track surface of drive box 3 has a large flatness, and also ensure the effective cooperation between the two teeth, and ensure that the movement mode of helical gear 2 is always rolling, in the embodiment, the helical gear 2 and the helical tooth structure 5 are tooth gap assembly interference structures.
[0066] Specifically, the interference amount of the tooth gap interference assembly is 1.3-1.5mm.
[0067] In order to further reduce the requirement for the flatness of the parts, and also reduce the abrasion between the parts, ensure the reliability and stability of the movement, the helical gear 2 and the helical tooth structure 5 are filled with silicon grease.
[0068] It should be noted that the flatness refers to placing the part on a standard marble measuring table, taking any measurement position multiple measurement points (more than 3) to establish a plane, the absolute value of the sum of the distances of multiple measurement points in each area to the plane is the flatness.
[0069] By adding silicone oil in the helical tooth gap 15, the requirement for flatness can be reduced, the qualified rate of the part is improved, the problem of high requirement for the flatness of the part, high cost due to unqualified parts in the production process is solved.
[0070] In order to effectively ensure the stability of the movement and eliminate the inherent backlash impact of the straight tooth reciprocation, the inclination angle of the helical tooth structure 5 is 20°-45°.
[0071] As a further improvement of the utility model, the bearing surface of the sliding rail 4 is provided with a checkered anti-skid structure.
[0072] As shown in Figure 3-Figure 7 The utility model provides a sliding door 13 which comprises a sliding door 13 driving mechanism, and the sliding door 13 is connected with the sliding door 13 driving mechanism through pin hole cooperation structure 14 to reciprocate under the driving of the sliding door 13 driving mechanism.
[0073] Specifically, the pin hole cooperation structure 14 comprises: a square pin provided on the sliding door 13, and a square hole provided on the sliding block assembly 1; the sliding door 13 is hung on the sliding block assembly 1; the square pin is inserted into the square hole; and then the sliding door 13 is fixed through a screw.
[0074] Further, as shown in Figure 3-7 The sliding door 13 transmits gravity to the sliding block assembly 1 through the pin hole cooperation structure 14. The helical gear 2 is installed on the sliding block assembly 1, the driving box 3 and the driving box cover 9 sandwich the sliding block assembly 1, the driving gear 10, the driving rack 11 and the stepping motor 12, so that the sliding block assembly 1 can only move in the left-right direction. The helical gear 2 cooperates with the helical tooth structure 5 on the bearing surface of the sliding rail 4 of the driving box 3; the tooth top of the helical tooth structure 5 on the driving box 3 is designed to be gap-fitted with the tooth bottom of the helical gear 2, so as to prevent the mutual dead top between the two from causing the sliding door 13 to be stuck; the fitting gap is between 0.3mm and 0.5mm. The two teeth of the helical gear 2 and the helical tooth structure 5 are fitted with an interference of between 1.3mm and 1.5mm; when the flatness of the sliding block assembly 1 or the sliding rail 4 of the driving box 3 is large, the effective cooperation between the two teeth can also be ensured, and the movement mode of the bearing helical gear 2 is always rolling. The bearing surface helical tooth structure 5 of the sliding rail 4 and the helical gear 2 can be synchronously smeared with silicone oil; when the flatness of the part is high, the silicone oil is less; when the flatness is low, the silicone oil is more; the requirement for the flatness of the part is further reduced, the wear between the parts is reduced, and the reliability and stability of the movement are ensured.
[0075] Furthermore, the tooth shape of the load-bearing surface of the sliding track 4 of the drive box 3 is designed to be helical, and the inclination angle is selected between 20°-45°. It can effectively ensure the smoothness of movement and eliminate the inherent tooth gap impact when the straight teeth move back and forth. Bearings 6 and rotating shafts 7 are provided in the helical gear 2. The rotating shaft 7 and the bearing 6 are made of iron material to ensure their strength. The helical gear 2 uses PA66 plastic with good wear resistance to reduce the sound at the point of cooperation with the helical tooth structure 5 of the drive box 3. When the gravity of the sliding door 13 increases, the tooth thickness 8 can be adjusted to increase its own strength, while increasing the contact area with the drive box 3 to prevent parts from being worn due to excessive pressure, causing movement jams and abnormal noises.
[0076] It should be noted that the helical gear matching is the most effective way to ensure that the movement mode is rolling. Of course, other methods can also be used, for example: the load-bearing surface of the sliding track 4 of the drive box 3 or the helical gear 2 is made into a tic-tac-toe ("#") texture to increase the roughness so that the helical gear 2 is in a rolling form during the movement.
[0077] The sliding door 13 of the present invention solves the abnormal problems such as abnormal movement noise and jamming caused by the increase in size and weight of the sliding door 13 by providing the helical gear 2, the helical tooth structure 5 and applying silicone grease in the meshing gap.
