Description

Technical Field

[0001] This disclosure relates to the field of razor technology, specifically to a razor head holder; this disclosure also relates to a razor. Background Technology

[0002] An electric shaver is a device that uses an electric motor to rotate the shaving head, thereby cutting human skin and hair. To achieve a comfortable and efficient shaving experience, the cutting part of an electric shaver that comes into contact with the skin needs to have flexible floating or rotating functions to closely conform to the contours of different users' skin.

[0003] In existing technologies, the rotation angle can be constrained by setting a limit block. However, the limit block often occupies a large amount of internal space in the shaver, resulting in structural complexity and increased failure rate. In addition, after long-term use, the limit block is prone to wear or loosening, which affects the accuracy and stability of rotation, reduces the lifespan of the shaver, and also causes an uncomfortable shaving experience for the user due to unstable shaver head rotation.

[0038] This disclosure provides a razor head holder and a razor, wherein the razor head holder is part of the razor. The razor head holder will be described in conjunction with the description of the specific structure and working principle of the razor below.

[0039] refer to Figure 1 The shaver disclosed herein includes a handle 200, a shaver head holder 100, and a shaver head assembly 300. The handle 200 can be configured in a shape suitable for holding, allowing the user to perform shaving operations by holding the handle 200. Specifically, a battery and a motor can be disposed within the cavity of the handle 200, with the battery supplying power to the motor, enabling the motor to provide driving power to the shaver head assembly 300.

[0040] A razor head holder 100 is disposed on a handheld portion 200. The razor head holder 100 includes a first mounting bracket 1, and a razor head assembly 300 is disposed on the first mounting bracket 1 of the razor head holder 100. Specifically, the razor head holder 100 is used to support the razor head assembly 300 on the handheld portion 200 and to transmit power from the motor to the razor head assembly 300. The first mounting bracket 1 can be configured as a bowl-shaped structure, thereby providing assembly space for the razor head assembly 300 and some parts of the razor head holder 100.

[0041] In this embodiment, the razor can be a three-blade razor. The three-blade design allows for a faster and more thorough shave, and is especially suitable for handling coarse or thick beards. (Reference) Figure 1The cutter head assembly 300 includes a symmetrically distributed first cutter head component, a second cutter head component, and a third cutter head component; the first mounting bracket 1 is provided with a symmetrically distributed first transmission component, a second transmission component, and a third transmission component. Under the action of the drive assembly, the first transmission component, the second transmission component, and the third transmission component are configured to drive the first cutter head component, the second cutter head component, and the third cutter head component to rotate, respectively.

[0042] Specifically, the shaving head assembly 300 includes a shaving head holder 304, which may have three through holes for mounting a first shaving head component, a second shaving head component, and a third shaving head component, respectively. The first, second, and third shaving head components can have identical structures, each including a foil holder 301, a blade foil assembly 302, and a foil retaining ring 303. The foil retaining ring 303 and the foil holder 301 are fixedly mounted at the through holes of the shaving head holder 304, clamping the blade foil assembly 302 within them. The blade foil assembly 302 can rotate under the action of the drive component, thereby achieving the shaving function.

[0043] like Figure 1 As shown, the shaver head holder 100 includes a gear carrier 54 installed in the chamber of the first mounting bracket 1. The gear carrier 54 has three through holes for mounting a first transmission component, a second transmission component, and a third transmission component, respectively. Below the gear carrier 54, the shaver head holder 100 also includes a drive assembly for transmission connection with a motor, specifically including a drive spindle 51, a spindle spring 52, and a spindle gear 53 transmissionally connected to the drive spindle 51. A through hole is provided at the center of the first mounting bracket 1, allowing the drive spindle 51 to pass downwards and connect to the output shaft of the motor. Under the drive of the motor, the drive spindle 51 drives the spindle gear 53 to rotate. The two ends of the spindle spring 52 abut against the drive spindle 51 and the spindle gear 53, respectively, thereby providing axial cushioning.

[0044] The first, second, and third transmission components can have completely identical structures. Each transmission component includes: a blade gear 61, a gear shaft 62, a drive shaft bracket 63, a drive shaft spring 64, and a blade drive shaft 65. The blade gear 61 is located below the gear carrier 54 and meshes with the main shaft gear 53. The gear shaft 62 extends upwards through a through hole in the gear carrier 54 and is connected to the drive shaft bracket 63 and the blade drive shaft 65. The blade drive shaft 65 is configured to be connected to the blade and foil assembly 302. During rotation, the main shaft gear 53 drives the blade and foil assembly 302 to rotate via the blade gear 61, gear shaft 62, drive shaft bracket 63, and blade drive shaft 65, thereby achieving the shaving function. The two ends of the drive shaft spring 64 abut against the drive shaft bracket 63 and the blade drive shaft 65, respectively, thereby providing axial cushioning.

[0045] In one embodiment of this disclosure, such as Figure 1 As shown, the shaver head holder 100 includes a first magnet 7, which is disposed below the gear carrier 54; correspondingly, the shaver head assembly 300 includes a second magnet 305, which is disposed above the shaver head holder 304. When the shaver is fully assembled, the first magnet 7 and the second magnet 305 attract each other, thereby achieving the adsorption and fixation of the shaver head holder 100 onto the shaver head assembly 300.

[0046] The basic structure and working principle of a shaver have been introduced above. The shaver head holder 100 can drive the shaver head assembly 300 to float and rotate relative to the handheld part 200, thereby closely conforming to the skin contours of different users. In existing conventional electric shavers, limit blocks are usually set to constrain the rotation angle, which makes the structure more complex, increases the failure rate, and after long-term use, the limit blocks are prone to wear or loosening, thereby affecting the accuracy and stability of rotation limit, reducing the service life of the shaver, and also causing users to experience an uncomfortable shaving experience due to unstable shaver head rotation. To solve this problem, this disclosure provides a new structure for the shaver head holder 100, which will be described in detail below.

[0047] refer to Figure 2 and Figure 3 The shaver head holder includes a first mounting bracket 1, a second mounting bracket 2, and a floating member 3. The second mounting bracket 2 is connected to the first mounting bracket 1, and the floating member 3 can be mounted on the handheld part 200. The first mounting bracket 1 and the second mounting bracket 2 are configured to rotate relative to the floating member 3 under external force. During shaving, the force of skin pressing against the shaver head assembly 300 causes the first mounting bracket 1 and the second mounting bracket 2 to rotate relative to the floating member 3, that is, relative to the handheld part 200. This allows for flexible and close conformation to the skin contour, reducing missed areas and improving comfort.

[0048] refer to Figure 2 For ease of description later, a first direction X1 and a second direction X2 are defined, with the first direction X1 being opposite to the second direction X2. Using the shaver head holder 100 as a reference frame, the direction of the handle 200 is the first direction X1, and the direction of the shaver head assembly 300 is the second direction X2. For a more intuitive understanding, refer to... Figure 2 The view direction is as follows: the bottom is the first direction X1, and the top is the second direction X2.

[0049] refer to Figure 3The first mounting bracket 1 has a through opening 14, and the second mounting bracket 2 is configured to enclose the first mounting bracket 1 to form a mounting space. The second mounting bracket 2 can be connected to the first mounting bracket 1 on the first direction X1 side. The floating member 3 includes a floating head 31 at least partially located in the mounting space. Specifically, the floating head 31 is located on the first direction X1 side of the first mounting bracket 1 and at least partially on the second direction X2 side of the second mounting bracket 2. (Reference) Figures 8 to 10 The floating head 31 is provided with a limiting part 32 extending in a direction away from the second mounting bracket 2 (i.e. towards the second direction X2), and the limiting part 32 is configured to extend into the through opening 14. When rotated to the limit position, the limiting part 32 is configured to abut against the inner wall of the through opening 14 to restrict the rotational freedom of the first mounting bracket 1 and the second mounting bracket 2.

[0050] This disclosure provides a reliable hard-limiting structure by providing a limiting part 32 extending into the through-hole 14 on the floating head 31. When the first mounting bracket 1 and the second mounting bracket 2 rotate relative to the floating member 3 to their limit positions, the limiting part 32 abuts against the inner wall of the through-hole 14, thereby preventing the first mounting bracket 1 from rotating further relative to the floating member 3. This effectively restricts the rotation range of the first mounting bracket 1 and the second mounting bracket 2, avoiding failure of the fit between components or structural damage due to excessive rotation. The limiting structure provided by this disclosure is simple, requiring no additional complex limiting components. While simplifying the structure, it ensures the accuracy of the limiting, making the rotation process flexible and controllable, and improving the reliability and safety of product use.

[0051] In one embodiment of this disclosure, reference is made to Figure 4 and Figure 6 The first mounting bracket 1 includes a main body 11, a mating part 12, and a connecting part 13 for connecting the main body 11 and the mating part 12. For example... Figure 5 As shown, the main body 11 has a mounting opening 111, and the connecting part 13 is configured to fix the mating part 12 in the mounting opening 111. The main body 11 forms a stable outer shell structure, thereby providing overall support, and the mating part 12 is used to form a sliding fit with the floating head 31. One end of the connecting part 13 is connected to the inner sidewall of the mounting opening 111, and the other end is connected to the outer sidewall of the mating part 12, thereby stably connecting the mating part 12 within the main body 11.

[0052] The main body 11, mating part 12, and connecting part 13 can be integrally formed or they can be designed separately, manufactured separately, and then assembled to form the first mounting bracket 1. In specific embodiments where the first mounting bracket 1 is not integrally formed, for example, in a design where the main body 11 and mating part 12 are designed separately, different materials or processes can be used for different parts. For example, the main body 11 can focus on structural strength, while the mating part 12 can focus on wear resistance, thereby optimizing performance while reducing overall cost and extending the service life of the shaver head holder 100.

[0053] refer to Figure 4 At least two connecting portions 13 are provided, and two adjacent connecting portions 13 are configured to together enclose the inner wall of the main body 11 and the outer wall of the mating portion 12 to form a through opening 14. In addition to fixing the mating portion 12 to the main body 11, the connecting portions 13 also form the through opening 14. The through opening 14 provides at least enough space for the limiting portion 32 to extend, achieving compact assembly between components, significantly improving space utilization, and avoiding a bulky overall structure. Simultaneously, the presence of the through opening 14 maintains sufficient movement clearance, ensuring that the first mounting bracket 1 and the second mounting bracket 2 can rotate flexibly relative to the floating member 3. Furthermore, the side wall 131 of the connecting portion 13 restricts the rotational freedom of the first mounting bracket 1 and the second mounting bracket 2. When rotated to the limit position, the limiting portion 32 abuts against the side wall 131 of the connecting portion 13, thereby preventing the first mounting bracket 1 from rotating further relative to the floating member 3.

[0054] In one embodiment of this disclosure, the connecting portion 13 and the through opening 14 are respectively configured to be symmetrically distributed along the circumferential direction of the mating portion 12; and / or, the limiting portion 32 is configured to be symmetrically distributed along the circumferential direction of the floating head 31. This symmetrical distribution ensures that the limiting forces in each direction are substantially uniform, preventing the first mounting bracket 1 from tilting or jamming due to uneven force during rotation, thus ensuring a smooth and stable rotation process. Furthermore, the symmetrical design can disperse the impact force during limiting, reduce wear on local components, extend the service life of the shaver head holder 100, and improve the overall stability of the structure, making the shaving process safer and more reliable.

[0055] In one specific embodiment of this disclosure, reference is made to Figure 7The connecting portion 13 and the through opening 14 are provided in even numbers, and the number of both is equal. Specifically, a first through opening 141 and a second through opening 142 are respectively provided on both sides of the connecting portion 13, wherein the size of the first through opening 141 is less than or equal to that of the second through opening 142. Specifically, the number of limiting portions 32 is half the number of through openings 14, and the limiting portions 32 are configured to extend into the first through opening 141. For example, in this embodiment, there may be six through openings 14 and six connecting portions 13, and three limiting portions 32, with the three limiting portions 32 extending into three first through openings 141 respectively.

[0056] In this embodiment, the six connecting parts 13 can be symmetrically distributed in pairs along the circumferential direction. Two adjacent connecting parts 13 are referred to as a group. A group of connecting parts 13 encloses a smaller first through-hole 141, and two groups of connecting parts 13 enclose a larger second through-hole 142. For each connecting part 13, a first through-hole 141 and a second through-hole 142 are respectively provided on its two sides. The number of limiting parts 32 is half the number of through-holes 14. The limiting parts 32 only extend into the first through-hole 141. The small size of the first through-hole 141 can play a precise limiting role. Specifically, the contact gap between the inner wall of the first through-hole 141 and the limiting part 32 is smaller, which can strictly constrain the rotation limit position of the first mounting bracket 1 and the second mounting bracket 2, avoid excessive rotation or wobble due to excessive fitting gap, ensure that the shaver head holder 100 rotates smoothly and is accurately positioned during use, and improve the stability and consistency during shaving.

[0057] It should be noted that, since the razor in this embodiment is a three-headed razor, a first mounting bracket 1 with an approximate clover shape is adopted, and the mounting opening 111 on its main body 11 is approximately circular. The layout of the six connecting parts 13 and the through openings 14 can form a finer support and spatial division in the circumferential direction, adapting to the arc-shaped contour of the first mounting bracket 1. The three limiting parts 32 are symmetrically distributed (approximately spaced 120° apart) corresponding to the three first through openings 141, thereby uniformly constraining rotation from three directions and ensuring balanced limiting force.

[0058] In another embodiment, the number of limiting parts 32 can be equal to the number of through openings 14. This equal number ensures that each limiting part 32 can correspond to a matching through opening 14 and connecting part 13, avoiding imbalance due to mismatch in the number of limiting parts. Specifically, the limiting parts 32 can be configured to correspond one-to-one with the through openings 14. Each limiting part 32 has a connecting part 13 on each opposite side in the rotation direction, and the dimension of the through opening 14 in the rotation direction corresponds to the maximum rotation angle of the first mounting bracket 1.

[0059] Alternatively, two adjacent limiting parts 32 can be configured to extend into the second through-hole 142 together, and multiple limiting parts 32 can be paired up and correspondingly extended into the symmetrically arranged second through-holes 142. As mentioned above, the second through-hole 142 is relatively large. By selecting the limiting parts 32 to extend into the larger second through-hole 142 and configuring them in pairs, the larger space can be fully utilized to achieve a more stable limiting fit, avoiding the first mounting bracket 1 from having too small a rotation angle due to space constraints.

[0060] In one embodiment of this disclosure, such as Figure 4 As shown, the first mounting bracket 1 is provided with a first arc surface 101 curved along the first direction X1, and the first arc surface 101 is the end face of the mating part 12 facing the floating head 31. Figure 8 As shown, the floating head 31 is configured to bend towards the first direction X1. The inner wall surface of the floating head 31 is designated as the first mating surface 311. The first mating surface 311 is adjacent to the first mounting bracket 1 and is configured to have the same curvature as the first arc surface 101 for sliding engagement with the first arc surface 101. Figure 11 As shown, the second mounting bracket 2 is provided with a second arc surface 201 that is curved along the first direction, such as... Figure 9 As shown, the outer wall surface of the floating head 31 is designated as the second mating surface 312. The second mating surface 312 is adjacent to the second mounting bracket 2 and is configured to have the same curvature as the second arc surface 201 so as to slide and engage with the second arc surface 201.

[0061] This disclosure achieves flexible rotation of the first mounting bracket 1 and the second mounting bracket 2 relative to the floating component 3 by setting an arc-shaped sliding fit structure between the first mounting bracket 1, the second mounting bracket 2, and the floating component 3, so that all three bend in the same direction (i.e., the first direction X1) and match their curvatures. This design breaks through the limitation of traditional shaver heads that can only float up and down within a small range, significantly increasing the range of motion of the shaver head holder 100, which can better conform to the skin contours of different users, ensuring that the head assembly 300 applies even pressure to the face during shaving and improving user comfort. The precise sliding fit between the first arc surface 101 and the first mating surface 311, and between the second arc surface 201 and the second mating surface 312, ensures the stability and smoothness of the rotation process and avoids shaking or jamming. In addition, this disclosure achieves the floating of the shaver head holder 100 without relying on springs, reducing the functional failure problem caused by the loss of spring elasticity, extending the service life of the shaver head holder 100, and enhancing the reliability of the shaver product.

[0062] Furthermore, this disclosure directly uses the inner and outer wall surfaces of the floating head 31 as the first mating surface 311 and the second mating surface 312, respectively. This eliminates the need for additional independent arc-shaped components, reducing the number of parts and assembly steps, making the overall structure of the floating component 3 more compact, reducing the possibility of assembly errors, and improving production efficiency. Regarding mating accuracy, this disclosure directly utilizes the arc surface formed by the floating head 31 itself, ensuring a more precise positional relationship between the first mating surface 311 and the second mating surface 312, avoiding arc-shaped positioning deviations, and thus guaranteeing the stability and smoothness of the sliding fit with the first arc surface 101 and the second arc surface 201.

[0063] In one specific embodiment of this disclosure, such as Figure 5 As shown, in the first direction X1, the projected area ratio of the mating part 12 and the mounting port 111 is 23%-43%. Within this ratio range, the mating part 12 can form a sufficiently large first arc surface 101 area, thereby significantly increasing the sliding contact area with the first mating surface 311 of the floating head 31, making the contact between the two more sufficient, effectively dispersing the force, avoiding excessive local wear concentration, and greatly enhancing the stability during the floating process, reducing swaying or displacement, and making the rotation of the first mounting bracket 1 relative to the floating component 3 smoother. In addition, the reasonable area ratio provides sufficient space for the mounting port 111 to form the through port 14, which facilitates the assembly of the limiting part 32 through the through port 14 and avoids structural interference.

[0064] In one embodiment of this disclosure, reference is made to Figure 3 , Figure 6 and Figure 10 The main body 11 has a slot 15 near the through opening 14. Specifically, the slot 15 can be a stepped surface structure near the through opening 14. The second mounting bracket 2 is located on the first mounting bracket 1 in the first direction X1. The second mounting bracket 2 has at least two fasteners 21 extending in the second direction X2. The fasteners 21 are configured to pass through the through opening 14 and engage with the slot 15. Specifically, the fasteners 21 can have a buckle-like structure that can stably engage with the slot 15 (stepped surface), thereby achieving a fixed connection between the first mounting bracket 1 and the second mounting bracket 2. The design of the fasteners 21 extending in the second direction X2 and passing through the through opening 14 makes full use of the space layout of the through opening 14, making the connection structure more compact and eliminating the need for additional installation space.

[0065] In one embodiment of this disclosure, the number of slots 15 is half the number of through openings 14, and the number of slots 15 is equal to the number of fasteners 21. Specifically, slots 15 may be provided only in the first through opening 141. The equal number of slots 15 and fasteners 21 ensures that each fastener 21 corresponds to a matching slot 15 and the first through opening 141, avoiding force imbalance caused by a mismatch in the number of components. Specifically, there are six through openings 14, and three slots 15 and three fasteners 21.

[0066] At least two connecting portions 13, at least two through openings 14, and at least two slots 15 are respectively configured to be symmetrically distributed along the circumferential direction of the mating portion 12; and / or, at least two fixing members 21 are configured to be symmetrically distributed along the circumferential direction of the second mounting bracket 2. The symmetrical distribution ensures that the force at each connecting point is evenly distributed along the circumferential direction, and the connection strength in each direction is basically consistent. This prevents damage due to excessive force at local connecting points or failure of fixation due to insufficient force at local connecting points, thereby improving the durability of the connection and enhancing the overall reliability of the shaver head holder 100.

[0067] In one embodiment of this disclosure, see Figure 3 and Figure 12 An elastic member 4 is disposed between the first mounting bracket 1 and the floating member 3. The first mounting bracket 1 and the second mounting bracket 2 are configured to have a vertical motion component relative to the floating member 3 under the action of an external force, and are configured to be able to return to their original position under the action of the elastic member 4. Specifically, the elastic member 4 includes an elastic pleat 42, and it may be made of elastic materials such as silicone or rubber. The elastic member 4 can provide at least a rebound force in the second direction X2. When the first mounting bracket 1 and the second mounting bracket 2 move relative to the floating member 3 in the first direction X1 under the action of an external force (it can move vertically downward or obliquely), the elastic member 4 is deformed by compression; when the external force is removed, the elastic member 4 drives the first mounting bracket 1 and the second mounting bracket 2 to return to their original position. The vertical floating function allows the shaver head holder 100 to better adapt to the ups and downs of the face, reduce local pressure during shaving, and improve the comfort of the fit. In addition, the flexible return characteristic of the elastic member 4 can buffer the impact of external forces, reduce rigid wear between components, and extend the service life of the shaver head holder 100.

[0068] In one embodiment of this disclosure, the elastic member 4 is configured to be sleeved on the second mounting bracket 2 to form a first assembly. The first assembly is configured to be sleeved on the floating member 3 so that the inner wall of the elastic member 4 mates with the floating member 3. Afterward, the fixing member 21 on the second mounting bracket 2 can be snapped into the slot 15 through the through-hole 14, thereby achieving assembly. The elastic member 4 is stably clamped between the second mounting bracket 2 and the floating member 3, ensuring uniform elastic force distribution and avoiding excessive or insufficient local elastic force due to installation misalignment. The tight fit between the elastic member 4 and the inner wall of the floating member 3 reliably transmits the reset elastic force and allows for flexible deformation with the floating motion, ensuring the smooth operation of the first mounting bracket 1 and the second mounting bracket 2 during floating and reset processes, and improving structural stability.

[0069] In one embodiment of this disclosure, reference is made to Figure 8 , Figure 9 , Figure 12 and Figure 13 The floating member 3 also includes a mounting base 33 and a positioning rib 34 for connecting the floating head 31 and the mounting base 33. The mounting base 33 is located on the first direction X1 side of the floating head 31. Specifically, the mounting base 33 can be constructed as a cylinder and is used to connect with the handheld part 200. The elastic member 4 is provided with a positioning groove 41, and the positioning rib 34 is constructed to be located within the positioning groove 41 to restrict the rotational freedom of the elastic member 4. The elastic member 4 is sleeved on the second mounting bracket 2 and can rotate relative to the floating member 3 together with the first mounting bracket 1 and the second mounting bracket 2. This disclosure achieves a flexible limiting and buffering protection function by cooperating between the positioning rib 34 of the floating member 3 and the positioning groove 41 of the elastic member 4, thereby restricting the rotational freedom of the elastic member 4.

[0070] Specifically, the structure of the positioning rib 34 embedded in the positioning groove 41 precisely constrains the circumferential rotation of the elastic member 4. The elastic member 4, made of silicone or rubber, is flexible, providing a buffering effect during the limiting process, reducing the rigid collisions of traditional hard limiting and lowering the risk of component wear. Furthermore, the integrated design of the mounting base 33 and the positioning rib 34 enhances the structural strength of the floating member 3, ensuring that the positioning rib 34 can stably withstand the limiting force of the elastic member 4, thus balancing limiting reliability with buffer protection.

[0071] In one embodiment of this disclosure, at least two positioning grooves 41 and positioning ribs 34 are provided, and the number of positioning grooves 41 and positioning ribs 34 is equal. This improves the balance between limiting and buffering, and the equal number ensures that each positioning rib 34 can correspond to a matching positioning groove 41, avoiding unilateral force due to mismatch. Specifically, four positioning grooves 41 and four positioning ribs 34 can be provided.

[0072] In one embodiment of this disclosure, at least two positioning grooves 41 are configured to be symmetrically distributed along the circumferential direction of the elastic member 4, and at least two positioning ribs 34 are configured to be symmetrically distributed along the circumferential direction of the floating member 3. For example, in the embodiment where four positioning grooves 41 and four positioning ribs 34 are respectively provided, the four positioning grooves 41 are configured to be evenly distributed along the circumferential direction of the elastic member 4, and the four positioning ribs 34 are configured to be evenly distributed along the circumferential direction of the floating member 3. The symmetrically distributed positioning grooves 41 and positioning ribs 34 make the circumferential limiting force evenly distributed, and the buffering force in each direction is basically the same, preventing the positioning ribs 34 or positioning grooves 41 from deforming due to excessive local force, while ensuring the stability of the first mounting bracket 1, the second mounting bracket 2 and the elastic member 4 during rotation relative to the floating member 3, reducing skewing or jamming, and improving the smooth experience during shaving.

[0073] In one embodiment of this disclosure, the first mounting bracket 1 and the second mounting bracket 2 can rotate at a maximum angle of 30-60° relative to the floating member 3. Specifically, the maximum angle range can be defined by the aforementioned rigid limit (the limiting part 32 cooperates with the side wall 131 of the connecting part 13) and the flexible limit (the positioning groove 41 cooperates with the positioning rib 34). The rotation range of 30-60° can avoid component failure or structural damage due to excessive rotation angle, while being sufficient to meet the needs of fitting different facial contours and ensure that the blade can flexibly fit the user's face. When rotating to near the maximum angle, the elastic member 4 can provide cushioning to reduce the impact force when the rigid limit contacts, reduce component wear, and extend service life.
